Description

A kind of sniper rifle Gunlock structure

Technical field

The utility model belongs to sniper rifle technical field, is related to a kind of sniper rifle Gunlock structure.

Background technology

Gunlock is the important component of sniper rifle, and gunlock, which is mainly pushed away, to be sprung into thorax, locking cartridge chamber, fires bullet, deposit By powder pressure, draw the function such as shell and ejection.But traditional sniper rifle gunlock has following problem：First, it is traditional Sniper rifle is during open locking, and firing pin tail is directly slided on gunlock helicoid, and firing pin is sliding contact, friction with gunlock Power is larger, and causing open and close to be locked, power is larger, and the aiming position destruction to sniper is larger, influences pointing accuracy；Second, it is traditional Sniper rifle is single ejector structure, it is impossible to ensure enough ejection power, ejector and the contact area at bullet bottom are small, pressure Greatly, to the scraping at bullet bottom than more serious, and coppering phenomenon is than more serious；3rd, traditional sniper rifle gunlock is smooth cylindrical Shape, dust storm is larger or zero degrees celsius below temperature environment under in use, gunlock is present by the hidden danger of the grains of sand or ice slag clamping stagnation, Influence shooting reliability.

Utility model content

The purpose of this utility model is exactly that there is provided a kind of smooth sniper rifle gunlock of open locking in order to solve the above problems Structure.

The utility model can be achieved through the following technical solutions：A kind of sniper rifle Gunlock structure, including body, the machine Internal portion is provided with centre bore, and the front portion of the centre bore of the body is provided with head, and the front end of the head is provided with locking tooth, Firing pin body, firing pin tail, striker spring and gunlock tail are installed in the endoporus of head and the body formation, it is characterised in that：Institute State firing pin tail provided with locking roller with body to coordinate, form roller locking.

Preferably, the front end of the head is provided with two parallel ejectors.

Preferably, the body it is cylindrical on be provided with spiral sediment ejection trough.

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

First, the utility model coordinates on firing pin tail provided with locking roller with body, forms roller locking, becomes firing pin Sliding contact between tail and body reduces frictional force to be in rolling contact so that open and close lock power reduces, and then ensure that rifle The fluency of machine open locking action, improves aiming, fire accuracy；

Second, the utility model holds the double ejector structures of setting before the handpiece, it is ensured that enough ejection strength, reduces Scraping and coppering phenomenon of the ejector to bullet bottom；

3rd, the utility model body it is cylindrical on be provided with spiral sediment ejection trough, with sand discharge and antifreeze function of freezing to death.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the sectional view of the line A-A along along Fig. 1.

Reference

1 is body, and 2 be head, and 21 be locking tooth, and 3 be firing pin body, and 4 be firing pin tail, and 5 be striker spring, and 6 be gunlock tail, 7 It is ejector for locking roller, 8,9 be spiral sediment ejection trough.

Embodiment

Embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.

In the present embodiment, the orientation or position of the instruction such as term " on " " under " " left side " " right side " " preceding " " rear " " upper end " " lower end " It is, based on orientation shown in the drawings or position relationship, to be for only for ease of description, rather than indicate or imply meaning to put relation Device or element must have specific orientation, with specific azimuth configuration or operation, therefore it is not intended that new to this practicality The limitation of type.

Referring to Fig. 1-Fig. 2, a kind of embodiment of sniper rifle Gunlock structure, including body 1, the inside of body 1 are provided with Centre bore, the front portion of the centre bore of the body 1 is provided with head 2, and the front end of the head 2 is provided with locking tooth 21, described Firing pin body 3, firing pin tail 4, striker spring 5 and gunlock tail 6, the firing pin tail 4 are installed in head 2 and the endoporus of the formation of body 1 Coordinate provided with locking roller 7 with body 1, form roller locking.The sliding contact become between firing pin tail 4 and body 1 is rolling Dynamic contact, reduces frictional force so that open and close lock power reduces, and then ensure that the fluency of gunlock open locking action, improves Aiming, fire accuracy.

The front end of the head 2 is provided with two parallel ejectors 8.Enough ejection strength is ensure that, ejection is reduced The scraping at very 8 pairs bullet bottoms and coppering phenomenon.

The body 1 it is cylindrical on be provided with spiral sediment ejection trough 9.With sand discharge and antifreeze function of freezing to death.

It should be noted that above example only to illustrate the technical solution of the utility model and unrestricted, this area It is to be appreciated by one skilled in the art that can be modified to the technical solution of the utility model or equivalent substitution, without de- From the objective and scope of technical solutions of the utility model, it all should cover among right of the present utility model.
