Description

Recoil vibration device for toy gun

technical field

The invention refers to a recoil vibration device for a toy gun, especially a recoil vibration device for a toy gun that can adjust the size of the recoil vibration and can be adjusted to no recoil vibration. the

Background technique

By the way, toy guns (especially commonly known as BB guns) have created products with recoil vibration in order to achieve the realism of real guns as much as possible. However, due to their imperfect structural design, they have certain shortcomings. the

As shown in Figure 1, it is an embodiment diagram of the recoil vibration device a' of the existing toy gun, which mainly refers to that the recoil vibration device is arranged on the piston 10 moving axis of the piston cylinder device b', and on the piston 10 The rear of the recoil vibrating device a' has a housing 20, a weight 30, a recoil spring 40 and a rear wall 50, the housing 20 is connected to the rear of the casing c' on the rear side of the piston cylinder device b', and the weight 30 1. The recoil spring 40 is arranged inside the housing 20, the recoil spring 40 is arranged between the heavy body 30 and the rear wall 50, the rear wall 50 is integrally arranged on the rear side of the housing 20, and the piston 10 rear of the piston cylinder device b' There is a piston spring 101, and one end of the piston spring 101 is accommodated inside the piston 10, and the other end is against the inner wall of the casing c', and a rod-shaped connecting part 60 is used to pass through the casing c', and is assembled on the piston Between 10 and 30 for heavy body. The toy gun is equipped with a transmission unit d', a pull unit e', and a bullet push unit f' under the piston cylinder device b'. When implementing, pull the pull unit e' to drive the transmission unit d', the piston cylinder device b', the bullet pushing unit f' to shoot the bullet, when the pull unit e' is pulled to link the transmission unit d', the piston 10 moves the connecting part 60 in the backward direction (as shown in Figure 2), and passes through the connecting The part 60 moves backward so that the weight 30 presses the recoil spring 40 backward, and when the compression limit of the recoil spring 40 is exceeded, it rebounds forward, while the piston 10 moves forward to eject the bullet (see also FIG. 1 ), and Simultaneously, the heavy body 30 also moves forward to generate a reaction force to cause recoil vibration. the

As can be seen from the above, the rear wall 50 is integrally arranged on the rear side of the housing 20, so if the internal parts of the housing 20 are damaged, they cannot be opened and replaced from the rear wall 50, which is inconvenient. It is determined by the weight of the heavy body 30, the elastic restoring force of the recoil spring 40 and the piston spring 101, but because the weight of the heavy body 30 is fixed, the elastic restoring force of the recoil spring 40 and the piston spring 101 is also fixed in principle , Therefore, it must have the generation of recoil force, and the recoil force size is fixed and can't be adjusted, certainly, also may cause the elastic fatigue of recoil spring 40 and piston spring 101 to reduce along with using for a long time. But in fact, the shooting accuracy of guns with recoil vibration is often worse than those without recoil vibration. This is an unavoidable thing. Therefore, for consumers who require high shooting accuracy, it has Guns with recoil shocks are not suitable. the

Furthermore, because a rod-shaped connecting portion 60 is assembled between the piston 10 and the heavy body 30 of the above-mentioned prior art, and the front end of the connecting portion 60 is hit by the inner wall of the piston 10 when the piston 10 moves backward, even the heavy body 30 The forward momentum will also cause the front end of the connecting portion 60 to collide with the inner wall of the piston 10, so that the structure of the inner wall of the piston 10 will be damaged after repeated implementation, thereby reducing its service life. Therefore, there is a need for improvement. the

Contents of the invention

For above-mentioned shortcoming, the object of the present invention is to make the rear wall change into detachable assembly on the rear side of the housing, and set the adjusting rod at the rear wall, which can adjust the size of the recoil vibration, and can be used by Adjusting to abut against the rear side of the heavy body forward not only enables easy maintenance operations, but also can be adjusted to have no recoil vibration, or can be adjusted in size when there is recoil vibration, which can improve the existing deficiencies . In addition, if the front end of the heavy body can be directly connected by the piston spring, the existing connecting part can be avoided, and the structure damage caused by the repeated impact of the inside of the piston on the existing connecting part can be avoided, so as to eliminate the above-mentioned existing defects. the

Therefore, the technical scheme of the present invention is that the recoil vibrating device is arranged on the rear of the piston cylinder device of the toy gun, and it has a housing, a weight, a recoil spring and a rear wall, and the housing is connected to the rear side of the piston cylinder device. There is a heavy body and a recoil spring inside the casing, and the recoil spring is arranged between the heavy body and the rear wall, and there is a piston spring behind the piston of the piston cylinder device, and the rear wall is detachably engaged On the rear side of the housing, an adjustment rod is set to penetrate the rear wall from the rear of the rear wall. The adjustment rod can be screwed in and out, and the front end of the adjustment rod can be screwed in to abut against the rear end of the heavy body. If the rear wall is provided with a screw hole, and the adjusting rod is provided with an external thread and penetrates the screw hole, after the adjusting rod penetrates the rear wall, the recoil spring is penetrated. In this way, when the front end of the adjusting rod is screwed in to abut against the rear end of the heavy body, there will be no recoil vibration effect at this time, and when the front end of the adjusting rod is rotated backward to move the front end away from the rear end of the heavy body, the front end of the adjusting rod will The distance between the rear end of the heavy body determines the size of the recoil vibration, that is, the distance is large, the recoil vibration is large, and the distance is small, and the recoil vibration is small.

In addition, the front end of the heavy body can directly abut against the rear end of the piston spring; wherein, the front end of the heavy body is provided with a socket portion, and the rear end of the piston spring is joined to the socket portion; and the heavy body is integrated with a heavy body body, The three parts of the extension part and the socket part, that is, the heavy body includes three parts in one body: the heavy body body, the extension part and the socket part, and the extension part is arranged between the heavy body body and the socket part, and the extension part, the sleeve part The connecting part passes through the casing on the rear side of the piston cylinder unit. In this structure, when the piston moves backward, the piston spring directly presses the heavy body backward to replace the existing connecting part, thereby preventing the piston from being damaged due to collision. Moreover, the volume and weight of the heavy body can be larger than the existing ones. Therefore, its recoil vibration effect can be improved. the

Therefore, the present invention provides a recoil vibrating device for a toy gun, which can be disassembled and provided with an adjustment rod through the rear wall, so that the elastic restoring force of the recoil spring and the piston spring can be adjusted, thereby adjusting the recoil force. And it can be beneficial to the maintenance of components, and can be adjusted to the effect of no recoil vibration, so as to cope with the use of different consumers. the

The present invention also provides a recoil vibration device for a toy gun. The front end of the heavy body of the recoil vibration device is directly connected to the piston spring on the rear side of the piston, which avoids the need to set the connecting part of the existing device and eliminates the internal pressure of the piston. Repeated collisions cause structural damage, thereby increasing its service life. the
