A paintball gun with a pressure gauge device includes a rear
cap, a pressure gauge, and a canopy. The rear cap has a first end
and a second end. The rear cap has a compartment at the first end
adapted to accommodate the pressure gauge. The second end of the
rear cap has a piston block. The piston block has an air passage
interconnecting with an air passage of the pressure gauge. The
canopy is fixed to the rear cap which is then secured to a rear end
of a barrel in the paintball gun. A triggering block is provided in
the barrel. The triggering block engages with the rear cap. This
design can obtain the air pressure within the paintball gun so that
the user may apply air pressure to the paintball gun when

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a paintball gun with a
pressure gauge device, and more particularly to a pressure gauge
mounted behind a triggering block in a barrel of the paintball gun
so that the user may constantly understand the air pressure in the
paintball gun to supply air when necessary.
[0003] 2. Description of the Prior Art
[0004] Air pressure is a major part for a paintball gun to shoot a
paint bullet. In order to know the air pressure in the paintball
gun, a conventional paintball gun only measures the air pressure of
an air cylinder. Another conventional paintball gun is to mount a
pressure gauge to the handle or the front of the paintball gun, and
then is sealed with glue to prevent leakage. However, the mounting
of the pressure gauge may hinder the user to grasp the handle, and
is unable to mount or dismount quickly.
[0005] A later design was delivered as shown in FIG. 6, which
comprises a fixing tube A, a switch rod B, a pushing rod C, a
swivel tube D, and a pressure gauge E. The fixing tube A is
connected to a barrel. The barrel is provided with an air passage F
and a one-way valve G at one side of the barrel. The fixing tube A
interconnects with the air passage F. The pushing rod C is located
in the fixing tube A and corresponds in position to the one-way
valve G. The switch rod B is mourned to the fixing tube A and
engages with the pushing rod C to push the one-way valve G to
interconnect with the air passage F. The swivel tube D is connected
with the pressure gauge E and fits onto the fixing tube A. The
swivel tube D and the fixing tube A are interconnected with each
other. The pressure gauge E is adapted to measure the air pressure
in the air passage F.
[0006] Although this design has solved the above-mentioned
problems, it still has some shortcomings such as:
[0007] 1. The air pressure device has to be purchased separately,
which increases the cost.
[0008] 2. The pressure gauge bulges out of the paintball gun, which
may interrupt the user.
[0009] 3. The pressure gauge is far away from the user, which is
not easy to read.
SUMMARY OF THE INVENTION
[0010] According to the present invention, there is provided a
paintball gun with a pressure gauge device comprising: [0011] a
rear cap having a first end and a second end, said first end being
formed with a compartment, said second end being provided with a
piston block, a first air sealing ring being provided on said
piston block, a second air sealing ring being provided on said rear
cap, a first air passage being formed between said first air
sealing ring and said second air sealing ring; [0012] a pressure
gauge accommodated in said compartment of said rear cap and
comprising a guiding rod, two sealing rings being provided on said
guiding rod, a second air passage being formed between said two
sealing rings, said second air passage interconnecting with said
first air passage; and [0013] a barrel comprising a triggering
block therein, said barrel having a rear end to connect with said
rear cap, said triggering block engaging with said rear cap, said
triggering block having a third air passage at a rear end thereof,
said third air passage interconnecting with said first air
passage.
[0014] Preferably, said rear cap further comprises a canopy, said
canopy being fixed to said rear cap.
[0015] Preferably, an air room is formed between said triggering
block and said barrel, said air room interconnecting with said
third air passage of said triggering block.
[0016] Preferably, a buffering ring is provided on said rear cap
for sealing with said triggering block.
[0017] Preferably, said pressure gauge has an engaging groove for
connection of a lid.
[0018] Preferably, said lid has a first through hole.
[0019] Preferably, said canopy has a second through hole
corresponding to said first through hole of said lid of said
pressure gauge.
[0020] Preferably, said canopy is in a taper shape.
[0021] It is the primary object of the present invention to provide
a paintball gun with a pressure gauge device, which is easy to read
the air pressure in the paintball gun.
[0022] It is another object of the present invention to provide a
paintball gun with a pressure gauge device, which provides a
pressure gauge installed on the paintball gun directly without any
other requirement for reading the air pressure in the paintball
gun.
[0023] It is a further object of the present invention to provide a
paintball gun with a pressure gauge device, which is located at the
rear of the paintball gun to facilitate the user to read the air
pressure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0030] As shown in FIGS. 1 and 2, a preferred embodiment of the
present invention comprises a rear cap 1, a pressure gauge 2, a
canopy 3, a barrel 4 and a triggering block 5.
[0031] The rear cap 1 has a first end and a second end. The first
end is formed with a compartment 11 adapted to receive the pressure
gauge 2. The second end is provided with a piston block 12. A first
air sealing ring 121 is provided on the piston block 12. A second
air sealing ring 14 is provided on the rear cap 1. A first air
passage 13 is formed between the first air sealing ring 121 and the
second air sealing ring 14, as shown in FIG. 3. The rear cap 1
further comprises a buffering ring 15 corresponding to the
triggering block 5 to buffer the back fire of the triggering block
5. A first threaded section 16 and a second threaded section 17 are
provided on the rear cap 1. The first threaded section 16 is for
the connection of the barrel 4, while the second threaded section 7
is for the connection of the canopy 3.
[0032] The pressure gauge 2 has a first end and a second end. A
guiding rod 21 is provided at the first end of the pressure gauge
2. Two sealing rings 22 are provided on the guiding rod 21. A
second air passage 23 is formed between the two sealing rings 22.
The pressure gauge 2 is formed with an engaging groove 24 around an
inner edge of the second end of the pressure gauge 2 for a lid 25
to be secured threat. The lid 25 has a first through hole 251 at a
center portion of the lid 25.
[0033] The canopy 3 is in a taper shape and has a threaded hole 32
corresponding to the second threaded section 17 of the rear cap 1
for connection purpose. The canopy 3 further has a second through
hole 31 at a center portion of the canopy 3, corresponding to the
first through hole 251 of the lid 25 of the pressure gauge 2.
[0034] The barrel 4 is formed with a third threaded section 41 at a
rear end thereof adapted to connect with the rear cap 1. The
triggering block 5 is located in the barrel 4. The triggering block
5 engages with the rear cp 1. An air room 42 is formed between the
barrel 4 and the triggering block 5.
[0035] The triggering block 5 has a third air passage 51 at a rear
end thereof. The third air passage 51 interconnects with the first
air passage 13 of the rear cap 1.
[0036] To assemble the present invention, as shown in FIGS. 2 and
3, the guiding rod 21 of the pressure gauge 2 is inserted into the
compartment 11 of the rear cap 1. The canopy 3 is screwed to the
second thread section 17. The rear cap 1 is connected to the rear
end of the barrel 4. The triggering block 5 in the barrel 4 engages
with the rear cap 1. The second air passage 23 of the pressure
gauge 2, the first air passage 13 of the rear cap 1, the third air
passage 51 of the triggering block 5, and the air room 42 formed
between the barrel 4 and the triggering block 5 are
interconnected.
[0037] To turn the pressure gauge 2 towards a different direction,
as shown in FIGS. 4 and 5, a tool is inserted through the second
through hole 31 of the canopy 3 and the first through hole 251 of
the lid 25 to turn the pressure gauge 2 in a desired direction.
[0038] Furthermore, the canopy 3 may be welded or glued to the rear
cap 1 after screwed together with the second threaded section 17 of
the rear cap 1, so that when it is necessary to disassemble the
present invention, the canopy 3 will be rotated to loosen the rear
cap 1 at the same time.
