Description

Technical Field

[0001] The utility model relates to the technical field of firearm auxiliary equipment, in particular to an anti-jamming mechanism for a cartridge presser. Background Technique

[0002] Loading cartridges into a magazine is usually done manually, which is slow, inefficient, laborious, and difficult. Therefore, using a magazine cartridge presser can improve efficiency and reduce the difficulty of cartridge pressing. In the prior art, the commonly fielded cartridge presser in the military is a plate-type cartridge presser with an integrally formed design for easy carrying. The unsealed bullets are poured into the ammunition reserve slot, then the bullets are arranged neatly and placed into the loading chute, and finally the bullets are pressed into the magazine through a bullet pushing slider. However, in the prior art, the bullet pushing slider must apply force evenly along the direction of the loading chute. If the force application direction is incorrect or the pressing force is too strong, it is easy to cause the bullet pushing slider to jam. Therefore, we have developed an anti-jamming mechanism for a cartridge presser. Content of the Utility Model

[0003] The purpose of the utility model is to provide an anti-jamming mechanism for a cartridge presser, which can prevent the bullet pushing slider from jamming caused by incorrect force application direction or excessive pressing force, and improve the usability and reliability of the cartridge presser when in use, so as to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution:

[0005] An anti-jamming mechanism for a cartridge presser, comprising a cartridge pressing plate and a bullet pushing slider. A ammunition reserve slot is provided at the upper end of the cartridge pressing plate, and a magazine slot is provided at one side of the ammunition reserve slot at the upper end of the cartridge pressing plate. The ammunition reserve slot and the magazine slot are connected and communicated through a loading chute. Bottom-fire grooves and bullet-head grooves are respectively provided on the two side walls of the loading chute. The bullet pushing slider is slidably arranged in the loading chute, and both sides of the bullet pushing slider are respectively slidably connected with the bottom-fire groove and the bullet-head groove. A support block is fixedly provided in the middle of the upper end of the bullet pushing slider, and the upper end of the support block extends outside the loading chute.

[0006] Preferably, a push plate is fixedly provided at the upper end of the support block, and the push plate is perpendicular to the support block.

[0007] Preferably, two first spherical grooves are respectively opened on both sides of the push plate. First ball bearings are slidably arranged in the first spherical grooves, and the first ball bearings are slidably connected with the side wall of the loading chute.

[0008] Preferably, second spherical grooves are respectively opened at the four corners of the bottom of the bullet pushing slider. Second ball bearings are slidably arranged in the second spherical grooves, and the second ball bearings are slidably connected with the bottom wall of the loading chute.

[0009] Preferably, the cross-section of the bullet-head groove is set to be V-shaped.

[0010] Preferably, a lifting groove is provided on one side of the elastic pressing disc.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] For the anti-jamming mechanism of the ammunition press, through the provided ammunition slot, ammunition pushing slider, ammunition loading chute, magazine slot, elastic pressing disc, lifting groove, push plate, support block, second ball, first ball, primer groove, and bullet head groove, the push plate is pushed. The push plate pushes the ammunition pushing slider through the support block. The second ball at the bottom of the ammunition pushing slider reduces the friction at the bottom of the ammunition pushing slider, preventing the ammunition pushing slider from jamming due to excessive pressing force. The first ball on the side of the support block can prevent the ammunition pushing slider from jamming due to uneven force application not along the direction of the ammunition loading chute. The present utility model can prevent the ammunition pushing slider from jamming caused by incorrect force application direction or excessive pressing force, improving the ease of use and reliability of the ammunition press during use.
