Abstract

The utility model relates to a firing and rammer mechanism for non-case ammunition. The utility model is characterized in that a piston (or a valve) is arranged in the mechanism for the impact of ammunition gas when the ammunition is fired; a rear seat (an opening) drives an ammunition returning hook of caseless ammunition which is clamped and held in the process of chambering to free from the ammunition according to the magnitude and the possessing condition of impact force so that the ammunition returning hook is fired. When the ammunition is misfired and the impact force is not enough, the ammunition returning hook still clamps and holds the ammunition, and a rear pull mechanism withdraws from a bore of the ammunition returning hook.

Description

The percussion discharging mechanism of caseless ammunition

The utility model belongs to a kind of percussion discharging mechanism that is applied to caseless ammunition.

Though the caseless ammunition misfire of the Shi Yonging difficulty that extracts now is through improving as DRP 2152181F41d-11 number, as if the gunpowder fractional combustion or crackedly still can't extract.

The purpose of this utility model is to provide a kind of percussion discharging mechanism of caseless ammunition, to solve above-mentioned difficulties.

The purpose of this utility model is achieved in that the annular firing pin in the mechanism is fixed on an end of the hook tube that extracts with screw thread, the slide block of piston is in chute, the retaining nail stops slide block, shank is by two shank openings of piston, there are the decorative pearl on top of an official cap and decorative pearl on top of an official cap spring in the both sides of shank opening, the piston spring is blocked by the back-up ring that is fixed in the hook tube that extracts with two drift bolts, back-up ring reaches up and down, and two roller grooves are fixed in the hook tube that extracts, the shank axle passes the axis hole of shank, two ends are against in the groove of the wheelbase roller in the up-down rollers groove, the extract hook and the neck of hook is one, is screwed on shank, and piston central bore axis zone opening has the firing pin path.

The utility model has the advantages that whether to determine whether to free ammunition according to the emission of caseless ammunition.

Below in conjunction with drawings and Examples the utility model is elaborated.

Fig. 1 is the structural representation of first embodiment of percussion discharging mechanism of caseless ammunition.

Fig. 2 is the structural representation of second embodiment of percussion discharging mechanism of caseless ammunition.

1. 4. liang of drift bolt 5. annular firing pin 6. screw threads 7. of hook tube 2. chutes 3. retaining nail hook 8. shanks 9. shank axles 10. axis holes 11. necks of hook 12. screws 13. pistons 14. shank openings 15. slide blocks 16. piston springs 17. decorative pearls on top of an official cap 18. decorative pearl on top of an official cap springs 19. firing pin paths 20. back-up rings 21. wheelbase rollers 22. grooves 23. roller grooves that extract that extract among Fig. 1

In-house annular firing pin 5 usefulness screw threads 6 are fixed on an end of the hook tube 1 that extracts among Fig. 1, the slide block 15 of piston 13 is in chute 2, retaining nail 3 stops slide block 15, shank 8 is by two shank openings 14 of piston 13, there are the decorative pearl on top of an official cap 17 and decorative pearl on top of an official cap spring 18 in the both sides of shank opening 14, the back-up ring 20 that piston spring 16 is fixed on two drift bolts 4 in the hook tube 1 that extracts blocks, back-up ring 20 reaches up and down, and two roller grooves 23 are fixed in the hook tube 1 that extracts, shank axle 9 passes the axis hole 10 of shank 8, two ends are against in the groove 22 of the wheelbase roller 21 in the up-down rollers groove 23, the hook 7 that extracts is one with the neck of hook 11, is fixed on the shank 8 with screw 12, and the regional opening of piston 13 central bore axis has firing pin path 19.

The 1. hook tube 2. annular firing pin 3. screw threads 4. valve frames 5. hook 6. valves 7. door-hinges 8. screws 9. valve springs 10. firing pin paths that extract that extract among Fig. 2

In-house annular firing pin 2 is fixed on the hook tube 1 that extracts through screw thread 3 among Fig. 2, valve frame 4 usefulness screws 8 are fixed on the hook tube 1 that extracts, sealing serves as the axle switch with door-hinge 7, and the hook 5 that extracts is fixed the position beyond the valve 6 on it, door-hinge 7 is fixed on the valve frame 4, have valve spring 9 fixing with door-hinge 7 on the door-hinge 7, two valves 6 have firing pin path 10 with thorax axis juncture area.

Gunlock drives the hook tube preshoot of extracting of this mechanism during use, pushing away caseless ammunition loads, in-house extracting is hooked under the effect of multiple spring power card and embraces caseless ammunition, firing pin percussion primer simultaneously, get angry the back powder gases with enough energy impact piston recoil or valve opening, by mechanical connection the hook pine of extracting is opened, free caseless ammunition, make its emission.Piston or valve set back by piston spring or valve spring force after breaking away from the powder gases effect.When caseless ammunition was misfire, piston or valve were failure to actuate, and the hook that extracts still blocks embraces ammunition, for extracting.
