Abstract

The utility model relates to a pistol bolt or lock device. A jack which can be deflecting is arranged inside the bolt, which can be stretched to withstand a rack and pulled back to be separate from the rack through the seesaw of a sleeve, so that the bolt can be in lock or unlock state. This bolt is in rigid locking state before the warhead is separated from the muzzle, afterwards the bolt is unlocked. Such a bolt has sufficient supporting strength and only need smaller locking and unlocking strength. The gas guiding automatism and the manual drive i.e. the single hand loading two working methods are suitable to be adopted in the use of the pistol with the bolt. Thereby the firing circulation can be completed. The former is suitable for man stoppers with higher work reliability and shooting accuracy, while the latter is suitable for the first bullet loading and the excluding of duds, which is in favour to quick firing responses.

Description

A kind of rifle bolt device that is fit to manual (one hand loads) and the automatic pistol of gas operated

The utility model belongs to a kind of rifle bolt (machine) constructional device of pistol, and it is the improvement to the conventional pistol bolt structure.For characteristics of the present utility model can be described, the state-of-art of present traditional automatic pistol need be described at first.

Since the automatic pistol one Bo Chate pistol of first practicality in 1893 came out, the automated manner of automatic pistol did not have heavily variation basically, promptly mainly contained short back seat formula automated manner of gun barrel and blowback automated manner.Both common ground are: rely on powder gases to act on cartridge case base, make automatic machine obtain energy and finish automatic circulation.Difference is: the former rifle bolt drives sleeve and gun barrel retreats jointly, is fit to the pistol cartridge of the big power of emission; The latter's rifle bolt only drives sleeve backwards, and gun barrel is fixed, and is fit to the pistol cartridge of the little power of emission.Its common defects is that rifle bolt is motion in the shooting overall process, and this can be influential to fire accuracy; In order to absorb energy of back seat, the quality of rifle bolt is bigger in addition, and the kick of generation is also bigger.

There is a deficiency for a long time in automatic pistol, and first exactly bullet loads and discharges the misfire bullet needs bimanualness, and this is to closely or even be very disadvantageous in aspectant fight.The beginning of this century, in the pistol of the free gunlock automated manner that uses low power bullet, the pistol (as homemade 77 more novel formula pistols) that can singlehanded load appearred.But because the kicker rigidity of blowback pistol is bigger, so this type of pistol exists one hand load effort and the little deficiency of power, so application is wideless.

The purpose of this utility model provides a kind of rifle bolt device, makes automatic pistol can adopt widely used gas operated automated manner in other variety of gun, and has the one hand labour-saving performance of loading.

The purpose of this utility model is achieved in that rifle bolt is made up of rifle bolt body, jack and firing pin body.Parts with matching have sleeve, gun platform and trigger.It is characterized in that: rifle bolt is positioned at the rear portion of sleeve, can be driven by sleeve to seesaw, and sleeve is to be to support to seesaw with the gun platform, and trigger can drive the sleeve motion.Jack in rifle bolt is positioned at its underpart, and can make yaw motion, and jack is deflection down, may be stuck in the locking that realizes rifle bolt in the locking step of gun platform; Jack is toward upper deflecting, and the locking step that can break away from gun platform is realized unblanking of rifle bolt.The yawing moment that can control jack within the specific limits that seesaws of sleeve is realized opening/locking of rifle bolt, promptly when shooting rifle bolt before bullet does not fly away from muzzle be to be blocking, after having only pressure after bullet flies away from muzzle and in the bore to be reduced to safe degree, rifle bolt is unblanked.

Accompanying drawing has reflected embodiment of the present utility model, is described as follows:

Fig. 1 is a pistol structure full figure, and Fig. 2 is opening/the locking schematic diagram of rifle bolt, and Fig. 3 is the state diagram of rifle bolt back seat each parts when putting in place.

Parts title explanation among the figure:

1. breach 8. rifle bolts 9. firing pin bodies 10. jack tail end boss 11. hammers 12. triggers 13. trigger posts 14. sleeve pipes 15 of kicker 2. sleeves 3. shell throwing-out windows 4. cartridge chambers 5. jack 6. latches 7. firing pin bodies. the locking step 16. magazine springs 17. shell case tail end grooves 18. rifle bolt front ends of gun platform draw the shell tongue

Below in conjunction with accompanying drawing present embodiment is described further:

In conjunction with Fig. 1.In cartridge chamber this moment [4] a misfire bullet (I bullet) is arranged, the position of trigger [12] is preceding.

In conjunction with Fig. 2, pull back trigger, can drive sleeve [2] and retreat.The latch of sleeve [6] drives earlier firing pin body [9] slow astern segment distance (latch moves on to the b point by a point of rifle bolt), and this segment distance is the free travel of sleeve, and rifle bolt [8] is in the locking shape always, to guarantee the bullet muzzle that flies out.When the breach [7] of firing pin body retreated the boss [10] that aligns jack [5] tail end, its boss can put in breach, thereby made the tail end of jack be subjected to the promotion of following magazine spring [16] and deflection has realized unblanking of rifle bolt.After a while, thus the latch of sleeve run into b point in the rifle bolt and drive rifle bolt and retreat jointly, rifle bolt extracts the misfire bullet out by a pair of shell tongue [18] that draws of its head.In the sleeve backwards process, also finish compression kicker [1] and overwhelm the action of hammer [11].

In conjunction with Fig. 3, when sleeve backwards puts in place, the bullet (II bullet) that always pushed down by rifle bolt is freed, under the promotion of magazine spring, worked the also positive alignment cartridge chamber that puts in place by item, the groove of its shell case tail end [17] stretches into into drawing in the shell tongue of rifle bolt, and the misfire bullet then is subjected to rushing to summit of bullet of below and shell throwing-out window [3] by the sleeve top is ejected.

Opposite with said process, after sleeve backwards puts in place, under the promotion of its kicker, answer forward into, in advancing again, the latch in the sleeve drives rifle bolt and advances again jointly and push away to spring into thorax, and when the front end of rifle bolt withstood the tail end of gun barrel, rifle bolt advanced and puts in place.At this moment the firing pin body continues to be subjected to the promotion of sleeve latch, the inclined-plane of its breach acts on mutually with the inclined-plane of jack tail end boss, make jack deflection (opposite with the direction of arrow shown in Figure 2), its tail end withstands in the locking step of gun platform [15], has realized the locking of rifle bolt.Afterwards, sleeve drives the firing pin body and covers remaining free travel (moving on to a point by the b point).At this moment, the firing pin body has been pushed down the boss of jack tail end to prevent unblanking of rifle bolt, and its head is near the fire in a stove before fuel is added of bullet.On the other hand, the plate machine is fastened by open hammer, is parked in the rear and is hitting state (shown in Fig. 1 dotted portion), pulls plate machine releasable hammer percussion bullet once more.This rifle bolt can be used the gas operated automated manner and promote, be after bullet is pulled the trigger, the gas promotion bullet disengaging shell case that gun propellant combustion produces HTHP moves along gun barrel, when bullet passes through the gas port of gun barrel, can derive gases at high pressure and act on sleeve, make sleeve backwards, to repeat said process.

Therefore, withdrawing from loading again of first bullet filling and misfire bullet finished with manual operation, and later shooting cyclic process is finished automatically.In addition, if the reliable locking of rifle bolt, promptly firing pin body breach inclined-plane is not depressed jack tail end boss, at this moment, and the several times of the overhang of firing pin body head when the distance of bullet primers surpasses hammer strike firing pin.Can prevent that bullet from cocking off, make rifle bolt have the function of insurance not in place.

The utility model compared with prior art has the following advantages:

1. aspect automatic: the closedown mode of rifle bolt is rigid locking in this device, and utilizes the mode that seesaws of sleeve to come real Opening/locking of existing rifle bolt adopts the pistol of this rifle bolt just can use the automated manner of gas operated. This automated manner extensively should Be used on the automatic weapon of long barrel, its advantage is automatic machine (moving components such as sleeve, rifle bolt) course of work reliability height, Be fit to the bullet of the big power of emission under the lighter front dike of action mass, emission element (gun barrel and rifle bolt) does not fly at bullet It is static going out before the muzzle, so fire accuracy is higher. This is conducive to improve reliability, accuracy and the portability that pistol uses.

2. aspect manual: for the gas operated automated manner, (this is because the rifle bolt of back two kinds of automated manners is in motion in the overall process of emission to the rigidity of the kicker of automatic machine than short back seat formula of traditional gun barrel and blowback little, its kicker also will play the function that postpones the automatic machine back seat, therefore general rigidity is bigger), the strength of pulling pistol sleeve is less like this, therefore adopt the pistol of this rifle bolt also to be fit to use manually the mode of operation of (one hand loads) the fail to explode bullet and loading again of loading of bullet and eliminating of run initially, to bring into play closely rapid-action ability of pistol.Be with a rotating sleeve pipe [14] in addition on plate column [13], when finger spurs trigger backward, can slide with the rotation of sleeve pipe in the joint of finger, can continuous conversion use the force, is convenient to finger and can use power.
