Piston-linked nozzle feed mechanism

Abstract

To provide a mechanism for stably feeding BB bullets by eliminating a tappet plate in feeding BB bullets of an electric airsoft gun with a built-in tappet plate. [Solution] This device has adhesive members 5 and 6 between the piston 1 and the nozzle 2, which link their movements; a stopper 4 is provided to restrict the movement of the nozzle, forcibly separating the piston head 3 and the nozzle 2; and members 7 and 8 with repulsive forces are used to advance the nozzle 2, thereby feeding the bullet.

Description

[Technical field]

[0001] This invention relates to a feeding mechanism for an electric airsoft gun with a built-in tappet plate. [Background technology]

[0002] Conventional bullet feed mechanisms use the rotation of a gear to move the nozzle back and forth via a tappet plate to feed bullets, or use air pressure to move the nozzle back and forth without the tappet plate. [Prior art documents] [Patent documents]

[0003] [Patent documents] Patent No. 2517539 Summary of the Invention [Problem to be solved by the invention]

[0004] The feeding method via the tappet plate may cause unstable operation depending on the operating conditions unless the shape of the tappet plate is optimized. Therefore, optimization of the shape of the tappet plate is necessary. Optimization of the shape of the tappet plate requires advanced knowledge and experience, and there is no general shape. On the other hand, in the method of feeding by moving the nozzle back and forth using air pressure, the compressed air in the cylinder cannot be fully utilized, so the initial velocity of the BB bullets may decrease. This invention is intended to solve the above-mentioned disadvantages. [Means for solving the problem]

[0005] The problem is solved by a mechanism that has an adhesive member between the piston and the nozzle, which links the movement of the piston and the nozzle, provides a stopper to restrict the movement of the nozzle, forcibly separates the piston head and the nozzle, and feeds the bullets by moving the nozzle forward with a member that has a repulsive force. Effect of the Invention

[0006] As mentioned above, the elimination of the tappet plate allows the electric airsoft gun to operate stably regardless of the operating conditions. In addition, compared to the method of feeding bullets by moving the nozzle back and forth using air pressure, the nozzle is moved back and forth via a member with adhesive and repulsive forces, so there is no loss of compressed air in the cylinder and it is possible to reduce the decrease in bullet speed.

[0008] The piston and the nozzle are members that have an attractive force. The cylinder head is a member that has a repulsive force. The stopper is connected to the nozzle. The movement of the nozzle is restricted by the stopper. The position of the nozzle is determined by the attractive and repulsive forces. EXAMPLES

[0009] An embodiment will now be described with reference to the accompanying drawings. 1 is the piston and contains magnet a (5), 2 is the nozzle and contains magnet b (6), 3 is the cylinder head and contains magnet c (7) and magnet d (8), and these are attached to the electric airsoft gun mechanism. 4 is the stopper that is connected to the nozzle.

[0010] The operation of the above configuration will be explained below. Figure 1 shows the state when the piston is in its most forward position (when firing a BB bullet). At this time, magnet a and magnet b are attracted to each other, and magnet c and magnet d are at their most distant positions. Figure 2 shows the state when the piston is retracting (halfway). At this time, magnets a and b are attracted to each other, and the nozzle retracts as the piston retracts. Figure 3 shows the state when the piston is retracting (when the stopper is activated). At this time, the retraction of the nozzle is stopped by the stopper. Figure 4 shows the state when the piston is retracting (when the nozzle is advancing). At this time, magnets a and b are separated by the stopper, so there is no attractive force. Also, the nozzle advances due to the repulsive force between magnets c and d. Returning to Figure 1, the series of operations is completed. [Explanation of symbols]
