Description

A kind of firearms with flexible gunlock

Technical field

The utility model relates to firearms accessory technical fields, and in particular to a kind of firearms with flexible gunlock.

Background technique

In the structure of the single-shots firearms such as shotgun, sniping gun, shotgun, principle transmitter structure of the gunlock as firearms Occupy biggish volume in firearms structure, in the prior art in order to guarantee the normal use of gunlock, in addition to needing on firearms Certain telescopic slide space must also be reserved for gunlock outside the installation space of reserved gunlock, just can guarantee by pulling rifle bolt real The functions such as existing bullets loading, thus cause the full rifle of firearms longer, firearms weight is larger, thereby reduces the balance of firearms Property.

The Chinese utility model patent of Publication No. CN206531426U disclosed one kind on September 29th, 2017 and snipes step Rifle Gunlock structure, including body, the internal body are equipped with centre bore, and the front of the centre bore of the body is equipped with head, The front end of the head is provided with locking tooth, is equipped with firing pin body, firing pin tail, firing pin in the inner hole that the head and body are formed Spring and gunlock tail, the firing pin tail is equipped with locking roller and body cooperates, and forms roller locking.Become firing pin tail and body Between sliding contact be to be in rolling contact, reduce frictional force, so that open and close lock power reduces, and then ensure that gunlock open locking The fluency of movement improves aiming, fire accuracy.

Summary of the invention

Too long, the complete biggish defect of rifle weight for the full rifle length of firearms existing in the prior art, the utility model are public A kind of telescopic gunlock has been opened, the length of firearms can be effectively shortened using the utility model, full rifle weight is reduced, to improve The tactical qualities of firearms.

The utility model is achieved through the following technical solutions above-mentioned purpose:

A kind of firearms with telescopic gunlock, including gun body are provided with casing in the gun body, it is characterised in that: institute It states sliding in casing and is provided with head set, sliding is provided with head set in the handpiece body, is provided with firing pin on the handpiece body Chamber, the firing pin is intracavitary to be provided with firing pin, and one end of the firing pin chamber is by end cap seal, and against having between end cap and firing pin Striker spring；Stop screw is provided in the casing, the end cap and head, which are put on, is provided with mutually matched thrust surface.

Cushion is provided on the breech face of the casing.

Compared with prior art, the utility model has the following beneficial effects:

1, the gun body of the utility model is internally provided with flexible gunslinging, and the flexible gunlock includes head set and handpiece body, The handpiece body is slideably positioned in head set, and the firing pin chamber for placing firing pin is provided on handpiece body, the firing pin chamber One end is provided with striker spring by end cap seal between end cap and firing pin, after the completion of shooting, handpiece body exists the utility model It is retracted under the action of recoil in head set, and then head set is driven to move to the breech face of casing, with prior art phase Than monoblock type gunlock to be separated into head set and the handpiece body for mutually sliding and being placed on together, and pass through the flexible of handpiece body Shorten the installation length of gunlock, to substantially reduce the outer dimension of gunlock, and then reaches and shorten whole rifle length, reduce firearms The purpose of weight.

2, the utility model is provided with cushion on the breech face of casing, reduces the impact between head set and casing Power can either improve stationarity of the firearms in shooting, while reducing impact and causing to firearms to reduce the recoil of firearms Damage, extend gun all parts service life.

Specific embodiment

The utility model will be described further by specific embodiment below:

Embodiment 1

Most preferred embodiment of the present embodiment as the utility model, it discloses a kind of firearms with telescopic gunlock, Specific structure is as shown in Figure 1 to Figure 3, including gun body 1, casing 2 is provided in the gun body 1, sliding is provided in the casing 2 Head set 3, the head, which covers in 3, is provided with stepped hole, and the small head end of the stepped hole slidably connects handpiece body 4, the machine It is provided with firing pin chamber 5 on head body 4, the both ends of firing pin chamber 5 are open, and one end is sealed by end cap 7, outside the other end and firing pin 6 Shape is adapted, and firing pin 6 is slideably positioned in handpiece body 4；The end cap 7 is adapted with the stub end of stepped hole, and and ladder Hole stub end is slidably matched；Striker spring 8 is provided in the firing pin chamber 5, the both ends of the striker spring 8 are born against in firing pin 6 Rear end face and end cap 7 on；The front end of the handpiece body 4 is provided with the card slot for being clamped bullet, and card slot and firing pin chamber 5 connect It is logical；It is provided with the stop screw 9 for covering 3 movement positions for limiting head on the casing 2, is gone back on the breech face of the casing 2 It is provided with cushion 11.

The course of work of the utility model is as follows: as shown in Figure 1, firing pin is rapidly inserted into front end under the action of striker spring Card slot in, and the fire in a stove before fuel is added for hitting bullet completes transmitting, rotates the lock state of rifle bolt contact handpiece body at this time, then pulls back Rifle bolt, and then handpiece body sliding in head covers is driven, drive head set to slide backward by handpiece body, in handpiece body and head Set slides backward and the ejection of head set and completion shell case when being in contact for end face, while completing under the action of cartridge clip inner spring Next hair bullet loads；

As shown in Fig. 2, being pulled to bottom in rifle bolt, and rifle bolt is pushed further along after completing upper bullet, at this time handpiece body phase front Movement, the card slot of handpiece body front end blocks bullet, and bullet is pushed to travel forward, and handpiece body passes through phase between end cap and head set The thrust surface mutually cooperated drives head set to travel forward, and head set is limited screw when moving to above cartridge clip stops to stop fortune It is dynamic, while head set pushes down the bullet in cartridge clip；And handpiece body then enters locked position of coupler, then completes machine by rotation gunlock The locking of head body.

Compared with the gunlock for being driven manual gun, monoblock type gunlock is separated by flexible gunlock described in the utility model Mutually sliding is placed on the set of head together and handpiece body, reduces the shape ruler of gunlock with the contraction of handpiece body by head set It is very little, to reduce space reserved for installation gunlock in gun, and then reach and shorten whole rifle length, reduces gun weight, mentions The purpose of high gun tactical qualities.
