Description

Technical Field

[0001] The present invention relates to the technical field of firearms, and particularly to a bidirectional magazine coupler for connecting the bottom of a magazine. Background Art

[0002] Conventional firearm magazines all exist in the form of a single magazine. With the needs of daily training and the development of war, firearm magazine couplers are used more and more widely in daily training and war.

[0003] At present, the commonly used magazine couplers in the firearm field all connect the magazines in the same direction and in a left-right parallel connection manner. A relatively simple way is to directly wrap two magazines together with tape, and the magazine couplers developed by professional manufacturers often use a mechanical structure locking form to achieve the left-right parallel connection of the magazines.

[0004] Since conventional firearm magazines are generally long strip-shaped, the left-right parallel connection will increase the size in the width direction of the magazine, which has a certain impact on carrying and operation. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a bidirectional magazine coupler for connecting the bottom of a magazine, which can realize the rapid connection of matching magazines, is used for the function expansion of the magazine, and is convenient to use.

[0006] The purpose of the present invention is achieved as follows:

[0007] A bidirectional magazine coupler for connecting the bottom of a magazine includes a coupler skeleton in the shape of a plate. Two mushroom head positioning pins are respectively arranged at the two thin-walled ends of the coupler skeleton, and coupler shells are formed on the two plate surfaces of the coupler skeleton.

[0008] The matching magazine has a magazine bottom cover, a spring support seat, and a spring. The magazine bottom cover is symmetrically (centrally symmetrically) provided with mounting and dismounting grooves. The mounting and dismounting grooves have a connected connection position and a dismounting position. The two mushroom head positioning pins can extend into the corresponding mounting and dismounting grooves and change positions by rotation. When the mushroom head positioning pins are in the connection position, the heads of the mushroom head positioning pins are axially positioned in the mounting and dismounting grooves (that is, the diameter of the head of the mushroom head positioning pin is greater than the diameter of the mounting and dismounting grooves at this position, and the head of the mushroom head positioning pin extends into the mounting and dismounting grooves and is stuck). When the mushroom head positioning pins are in the dismounting position, the heads of the mushroom head positioning pins can withdraw from the dismounting position (that is, the diameter of the head of the mushroom head positioning pin is less than or equal to the diameter of the mounting and dismounting grooves at this position). When the heads of the mushroom head positioning pins extend into the magazine bottom cover, the spring support seat compresses the spring and moves along the inside of the magazine body to make way.

[0009] On the support spring seat, cylindrical pits are respectively provided corresponding to the two mushroom head locating pins. When the mushroom head locating pins are in the connection position, under the action of the support spring, the cylindrical pits accommodate the heads of the mushroom head locating pins and limit the position (preventing the matching magazine from rotating and changing position), so that the mushroom head locating pins cannot withdraw from the cylindrical pits.

[0010] Preferably, the mushroom head locating pins are fixedly connected to the coupler skeleton by inserting locking pins.

[0011] Preferably, the head of the mushroom head locating pin is a cylinder, and its end face is provided with a chamfer to facilitate the insertion into the bottom cover of the magazine.

[0012] Preferably, the coupler housing is made of plastic material and is injection molded on the coupler skeleton.

[0013] Preferably, the coupler housing is provided with anti-slip grooves, and the anti-slip grooves correspond to the outer shape of the matching magazine.

[0014] Preferably, when connected in the forward direction, the installation directions of the two matching magazines corresponding to the coupler are the same, and at this time, the bullet directions in the two magazines are consistent. When connected in the reverse direction, the installation directions of the two matching magazines corresponding to the coupler are opposite, and at this time, the bullet directions in the two magazines are opposite.

[0015] Preferably, it further includes a disassembly tool. The disassembly tool is provided with an insertion head. The insertion head is provided with a guiding conical surface. On both sides of the tail end of the matching magazine, there are jacks. The insertion head is used to insert into the jacks, and the insertion head can lift the support spring seat through the surface, so that the mushroom head locating pins withdraw from the cylindrical pits.

[0016] Due to the adoption of the above technical solutions, the present invention is more applicable to the bottom connection of short magazines of civilian firearms. The length after connection is still less than that of conventional firearm magazines. It is no different from conventional magazines in terms of carrying and operation, and even improves the installation convenience of short magazines of civilian firearms. At the same time, it is more beneficial to the holding of the magazine bin position of the firearm. The present invention can also be extended to the bottom connection of military firearm magazines, and it is more suitable for the use of short magazines with about 5 rounds. To meet the connection of short magazines, it not only satisfies the connection and use of magazines, improves the efficiency of changing magazines, shortens the training and combat time, but also saves the number of magazines carried. At the same time, it also extends the holding position of the magazine bin of short magazine firearms, making the holding more comfortable. The present invention also has the following beneficial effects:

[0017] 1. The present invention innovatively adopts the method of bottom connection of magazines to realize the connection and use of two magazines.

[0018] 2. The connection method of the present invention is simple, easy to understand and convenient to operate.

[0019] 3. The present invention can realize two-way connection (forward connection, reverse connection), providing multiple implementation ways for users to change magazines.

[0020] 4. The product of the present invention has a simple structure and few parts. Both the connector skeleton and the connector housing can be manufactured by die molding, which is more suitable for mass production and has a low cost. BRIEF DESCRIPTION OF THE DRAWINGS
