Abstract

The invention relates to a pump type shotgun lock catch, which comprises a lock catch, wherein a stretching arm is arranged on the lock catch; and an inclined surface which is pressed against an inclined surface on the lower part of the front end of a bolt frame is arranged on the stretching arm. The pump type shotgun lock catch is simple in structure, reasonable in design, reliable in mechanism motion and high in processing manufacturability. Requirements for the mechanism motion are met, two parts namely an in-place safety mechanism and an in-place safety spring are eliminated, the machining process of assembly spring grooves and limiting parts for the in-place safety mechanism and the in-place safety spring on a trigger seat is eliminated, the machining procedures of the parts are reduced, and labor cost and tool cost for parts processing are reduced.

Description

Pump type Shotgun snap close
Technical field
The present invention relates to a kind of application pump type Shotgun locker, particularly relate to and a kind ofly stop the snap close that next bullet delivers from godown after can discharging bullet a to conveyer.
Background technology
At present, known pump type Shotgun be adopt bilateral resistance bullet device alternately, the stopping and discharging of ordered control bullet, or adopt one-sided resistance bullet device, discharge bullet a to conveyer and stop next ejection storehouse with common completion of the insurance that puts in place.Its mode that adopts is to overwhelm through in the process of gunlock recoil, pulling the trigger hammer in the transmitter module that mainspring is compressed when realizing being furious action, thereby the insurance that puts in place is resetted under the insurance spring power effect that puts in place, realizes thereby free its extruding to snap close.
Summary of the invention
The objective of the invention is to overcome the weak point that exists in the above-mentioned technology; Provide a kind of simple in structure, reasonable in design; Mechanism action is more reliable, and control discharges a bullet and stops that simultaneously next bullet delivers from godown and realizes hole capital after selling all securities on-hook purpose pump type Shotgun snap close from magazine.
In order to achieve the above object, the technical scheme that the present invention adopts is: comprise snap close, on snap close, be provided with cantilever arm, cantilever arm is provided with the inclined-plane that the inclined-plane with breech housing front end bottom is abutted against each other.
Advantage of the present invention is:
Simple in structure, reasonable in design, mechanism action is more reliable, and processing technology is good.When satisfying the mechanism action requirement; The one, simplify and fallen put in place the insurance and these two parts of insurance spring that put in place; The 2nd, cancelled the processing at put in place on the percussion support insurance and put in place two part assembling spring grooves of insurance spring and spacing position; Reduce the manufacturing procedure of this part, reduced the cost of labor and the cost of charp tool of part processing.
Description of drawings
Fig. 1 is a buckle structure sketch map of the present invention;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is a breech housing structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described in further detail.
Can be known by Fig. 1-Fig. 3, the present invention includes snap close 1, on snap close 1, be provided with cantilever arm 2, cantilever arm 2 is provided with the inclined-plane 3 that the inclined-plane 7 with breech housing 6 front end bottoms is abutted against each other.
The present invention is when to be pulled the trigger, and snap close cantilever arm 2 is pushed in breech housing 6 sides, and snap close head 8 retainings stop bullet to deliver from godown at the magazine mouth at this moment.After the bullet percussion, breech housing 6 is the recoil under the effect of powder gases, when the recoil certain distance in the bore; Slip in the process that cooperates inclined-plane 7 through cooperating inclined-plane 3 at cantilever arm 2, snap close 1 is under the effect of snap close spring 5 power, and snap close 1 completion is around the spinning movement of snap close axle 4; Its head 8 leaves the magazine mouth, and the restriction at the bottom of the bullet bullet that delivers from godown is treated in releasing, and bullet delivers from godown under the promotion of magazine spring; The bullet extruding snap close side in the process of delivering from godown, snap close spring 5 is compressed again, and snap close is around 4 rotations of snap close axle; Its head 8 goes to the magazine mouth again, blocks next bullet and delivers from godown.
The present invention cancels put in place the insurance and these two the useless parts that lose function of insurance spring that put in place in the percussion trigger mechanism; Rely on breech housing reciprocating action directly to the control of snap close action, realized discharging bullet a to conveyer and stopped the deliver from godown basic change of this mechanism action implementation of next bullet.
