Description

A kind of pistol structure

Technical field

The utility model relates to the field that manufactures and designs of weapon, a kind of novel structure of pistol specifically.

Background technology

Existing pistol mostly is a tube-in-tube structure, be that gun barrel is in the sleeve the inside, unblank when powder gases causes during emission kick promotes the sleeve back seat and extract empty-cartridge-case out, each percussion makes the friction repeatedly of gun barrel and sleeve, cause the heavy wear of gun barrel and sleeve, influenced fire accuracy and service life greatly.

Summary of the invention

The utility model is for solving gun barrel and tube-in-tube structure pistol, and the shooting problem that accuracy is poor, service life is low designs a kind of built-in gunlock, and gun barrel is fixed on upper casing pistol structure by screw thread.

The technical solution of the utility model is, a kind of pistol structure, comprise shell, gun barrel, sleeve, magazine, trigger, its special character is, vertical magazine is housed in the enclosure, and gunlock is equipped with in the top of magazine, horizontal firing pin is housed in the gunlock, firing pin is peripherally equipped with striker spring, and the rear side of firing pin is equipped with hammer, hammer is connect by hammer pin and shell, and running fire sear, mainspring are housed on the hammer pin; Upper casing is housed above the gunlock, and bore is left in the front side of firing pin, and the front end of upper casing is equipped with gun barrel, gun barrel be peripherally equipped with the sleeve spring, the sleeve spring be peripherally equipped with sleeve; The downside of gun barrel leaves the air guide chamber, leave the gas port that communicates between gun barrel front end and the air guide chamber, the locking tenon is equipped with at the end opening place of gas port, horizontal gunlock kicker is equipped with at the rear portion of air guide chamber, the front end of gunlock kicker is equipped with round end spike locking push rod, the locking push rod touches mutually with the posterior angle of locking tenon, and the posterior angle of locking tenon becomes chamfering; The lower rear of air guide chamber is equipped with trigger, and trigger and hammer driving lever are integral shape, and hammer driving lever postposition cooperates connection with hammer.

During use, earlier hand-held shell installs magazine, the machine drawing sleeve that pulls back the shell upper forepart is unblanked, promote to move behind the gunlock, bullet moves in magazine, and gunlock promotes first bullet and enters bore after loosing one's grip under the effect of gunlock kicker, locks under the effect of locking tenon, simultaneously, machine drawing sleeve return under the effect of sleeve spring.Aim at target to be shot then, detain trigger and promote to move behind the hammer driving lever and overwhelm and discharge hammer, firing pin is knocked in hammer resilience under the effect of mainspring, and firing pin front end bump primer outburst bullet penetrates; When the capable gun barrel front end of bullet, the gas port of powder gases by the gun barrel front end presses down the locking tenon of gunlock and unblanks, simultaneously, gunlock moves and extracts out empty-cartridge-case after under the reaction of gun barrel rear portion powder gases, the locking tenon is by the chamfering of posterior angle and cooperating of locking push rod round end, move second bullet of promotion behind the promotion gunlock kicker and load, gunlock is finished locking under the effect of locking push rod.

The running fire function is on the basis of single-shot, and with the rearmost end of trigger button, trigger promotes to move behind the spring leaf, with the running fire pull bar to pusher, the running fire pull bar blocks the running fire sear when hammer is overwhelmed by gunlock, and when gunlock return during near terminal point, gunlock pulling running fire pull bar discharges hammer and finishes running fire.

The utility model adopts built-in hammer, and hammer and firing pin be kept closed, can be because of falling or accidental impact causes and cocks off.

Technique effect of the present utility model is, adopts above-mentioned technical scheme, can realize a kind ofly not only can improving the service life and the accuracy of fire, and because number of components is few, simple in structure can reducing production costs, the pistol that mounting or dismounting are convenient, safe and reliable.

Description of drawings

Fig. 1 is a structural front view of the present utility model, and the accompanying drawing that makes an abstract.

Fig. 2 is a right side view of the present utility model.
