Description

  The present invention relates to a toy gun structure, and more particularly to a recoil transmission structure disposed inside a toy gun.

  Toy guns (also called BB bullets) are widely loved by people. A conventional toy gun has members such as a transmission unit, a trigger unit, and a bullet pushing unit arranged inside the toy, and has only a function of firing a small bullet, and lacks realism and realism. In order to pursue a realistic feeling similar to that of a real gun, the manufacturer generates a reaction force at the moment the bullet is fired, and a recoil generation structure that creates the effect of recoil shock (blowback reaction) is placed inside the gun. did.

  In the conventional recoil generating structure, members such as a piston, a piston spring, a guide rod, a weight, and a recoil spring are generally mounted in the internal space of the toy gun case. The recoil spring is disposed between the weight and the rear wall located in the shoulder rest of the toy gun case. The guide rod penetrates the case stopper and is interposed between the piston and the weight. In all conventional recoil generating structures, the guide rod and the weight are connected and interlocked.

The conventional toy gun recoil generating structure has the following problems (1) to (3).
(1) When the interlocking rhythms of the reciprocating motions of the piston and the weight do not match (for example, when the weight moves forward and the piston moves backward), the substantial connection between the guide rod and the weight causes the gear set and The piston may be damaged.
(2) The shooting sound is not loud and clear.
(3) Although it is necessary to dispose the stopper plate inside the shoulder pad and stop the weight pushed out before, there is a risk that the parts may be damaged. Further, since the stopper plate is arranged, the weight cannot move in the maximum stroke.

A first object of the present invention is to provide a recoil transmission structure for a toy gun that solves the conventional problems.
A second object of the present invention is to provide a recoil transmission structure for a toy gun having an extendable guide rod.
A third object of the present invention is to provide a toy gun recoil transmission structure in which a guide rod and a weight are separated.

In order to solve the above-mentioned problems, the present invention provides a toy gun having a piston, a weight, and a recoil spring arranged on one axis so as to obtain a recoil shock with a weight that moves by a reciprocating motion of the piston at the time of bullet firing. A recoil transmission structure having a hollow portion and interlocking with the reciprocating motion of the piston, a transmission rod disposed in the hollow portion of the transmission rod, and one end abutting against the buffer rod spring And a buffer rod that is slidable in the hollow portion and capable of retracting the weight at the other end.

The toy gun recoil transmission structure of the present invention has the following effects (1) to (6).
(1) When the interlocking rhythm of the reciprocating motion of the piston and weight does not match, the buffer rod spring in the telescopic guide rod absorbs part of the kinetic energy coming from the weight, and the front end of the buffer rod directly hits the piston and is damaged. Can be prevented.
(2) Since the telescopic guide rod and the weight are not substantially connected but separated, the kinetic energy of the recoil shock can be skillfully transmitted, and the untransmitted motion can be partially absorbed.
(3) When the telescopic guide rod hits the weight, a clear metal collision sound is generated, and a very favorable real feeling is born. In addition, the collision sound generated when the weight moves forward and hits the tail end of the barrel metal (ie, the stopper of the case) is large and clear.
(4) In the conventional structure, it is necessary to stop the weight to be pushed forward by the stopper plate disposed in the shoulder pad portion. However, this may damage the parts. However, the present invention does not require a stopper plate and has a simple structure. Also, when the weight moves forward, the weight hits the tail end of the barrel metal and stops, so it can move at the maximum stroke.
(5) The telescopic guide rod has a two or more-stage member structure, and since the buffer rod spring is disposed inside, it has a preferable buffer function and can maintain an appropriate distance between the piston and the weight. it can.
(6) In the conventional structure, there is a risk that the gear set and the piston may be damaged when the piston moves in the reverse direction and backward, but the telescopic guide rod of the present invention has a buffering function. Such a problem does not occur.
