ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a paintball gun conveniently assembled, particularly to one having a through hole formed in a back of a grip, communicated with a chamber of the grip; a set bolt provided with at least one engagement groove disposed thereon and capable of being extended into the through hole with an inner end protruded into the chamber and pressed against one wall surface of a magnetic-attraction plate; a setscrew hole formed in one sidewall surface of the grip and communicated with the through hole for being screwed with a setscrew, by which the set bolt designed to have different length for being assembled with a gun body of different style can be extended into the through hole to push the magnetic-attraction plate, and then screwed with the setscrew tightly to keep the set bolt in a fixed position so that a push rod of the magnetic-attraction plate can push a lower end of a locking member to adjust the displacement height of an upper end of the locking member to be fitted with different types of gun bodies, thus a single grip is suited for being conveniently and quickly assembled with a gun body of different style.
2. Description of the Prior Art
A known conventional paintball gun, as shown in
FIG. 1
, mainly includes a grip
1
and a gun body
2
. A recess
10
is disposed inside the grip
1
and provided with a circuit board
11
and an electromagnet
12
therein. A chamber
13
disposed above the recess
10
and communicated with the recess
10
is provided with an electromagnetic valve
14
therein. A magnetic-attraction plate
15
disposed at one side of the electromagnetic valve
14
has a push rod
150
extended through the electromagnetic valve
14
and protruded from the other side of the electromagnetic valve
14
. A locking member
16
pivoted on an upper portion of the grip
1
has an upper end whose bottom is urged upward by a spring
17
disposed below and a lower end pushed against by an outer end of the push rod
150
. A trigger
18
disposed in front of the grip
1
has an actuator
19
located in back of the trigger
18
. The grip
1
is fixed beneath the gun body
2
. The gun body
2
has a slide way
20
disposed at a bottom of the gun body
2
for accommodating the upper end of the locking member
16
, an air chamber
21
provided with a recoil rod
22
therein. A locking groove
23
is formed at a bottom of the recoil rod
22
for firmly engaging the locking member
16
. A firing chamber
24
located above the air chamber
21
has a pull rod
25
disposed at a rear of the firing chamber
24
and provided with a linking rod
26
connected with the recoil rod
22
, by which a pull of the pull rod
25
will make the recoil rod
22
moved accordingly.
However, the known conventional paintball gun has the locking member
16
of the grip
1
with a fixed height in its engaging position hard to be make any adjustment, which is only suited for being combined with one specific gun body
2
. In case of being combined with a different gun body
2
, a fitted grip
1
is required and thus greatly increases the production cost.
SUMMARY OF THE INVENTION
The main purpose of the invention is to offer a paintball gun capable of being assembled conveniently and quickly.
The main feature of the invention is to provide a paintball gun conveniently assembled having a through hole formed in a back of a grip and communicated with a chamber of the grip; a set bolt provided with at least one engagement groove disposed thereon and capable of being extended into the through hole with an inner end protruded into the chamber and pressed against a wall surface of a magnetic-attraction plate; a setscrew hole formed in one sidewall surface of the grip and communicated with the through hole for being screwed with a setscrew.
