BB bomb toy gun barrel structure

This creation is related to the barrel structure of a BB bomb toy gun, especially one that allows the BB to improve its flight stability and range after shooting.

According to FIG. 1 , a conventional BB toy shooting device 1 mainly includes a BB projectile 11 , a moving device 12 and a barrel 13 .

When the BB bomb 2 is to be fired, the BB projectile 2 will be advanced into the rifle 121 of the cutting device 12 and form abutting position with the tangential cross yoke 122, and then the BB projectile 11 outputs a high pressure gas. The BB projectile 2 is pushed to the direction of the barrel 13 by the high-pressure gas, and the BB pin 2 is pushed to the initial stage, and the round cut point of the dome above the BB bouncer 2 is subjected to the shearing cross-bar 122 of the cutting device 12. Pressed, at this time, the BB bomb 2 forms a moment, so that the BB bomb 2 can obtain a self-rotating rotary cutting action power, and the auto-rotation action causes the BB bomb 2 to be shot out of the barrel 13 Eliminate the resistance of the air in the atmosphere, and thus achieve the effect of increasing the range of the BB bomb 2 range.

However, as shown in FIG. 2, the particle diameter of the BB bomb 2 is slightly smaller than the inner diameter of the barrel 13, so that the BB bomb 2 and the inner wall of the barrel 13 still have some slight space, so the BB bomb 2 is launched. And after the cutting of the shearing device 122 by the cutting device 12, when the BB bomb 2 advances in the barrel 13, it will collide with the inner wall of the barrel 13 several times, thus, On the one hand, it will offset and reduce the force of the BB bomb 2 to shoot forward, on the one hand, it will affect the stability of the BB bomb 2; therefore, after the BB bomb 2 shoots the barrel 13, the BB bomb 2 will be shortened. Its range distance will also easily lose the accuracy of its shooting point due to poor stability.

To this end, how to make a BB bomb 2 can increase its range distance and improve its stability during flight is a problem that the relevant industry needs to overcome.

This creation is to overcome the shortcomings of the poor BB range and poor stability during flight when the BB bullet gun is fired.

To this end, the creation provides a barrel structure of a BB bomb toy gun. The barrel structure of the BB bomb toy gun of the present invention comprises a barrel, the barrel is a hollow tube body, and has a filling end and a striking end, and the filling end has a first pipe, and The attacking end has a second pipe, and the first pipe and the second pipe are in communication with each other, and the inner diameter of the second pipe is larger than the inner diameter of the first pipe.

The application technology of the creation and the application effect of the creation is that the second pipeline in the barrel is larger than the first pipeline, so that the BB bomb can be launched and the second pipeline enters the second pipeline, so that the BB bomb The number of collisions and the frequency of the collision generated in the second pipeline are reduced, so that the energy loss of the forward flight of the BB bomb caused by the collision can be reduced, and the stability of the flight of the BB bomb can be improved; on the other hand, there will be more in the second pipeline. More high-pressure gas quickly ran to the front of the BB, which in turn produced a white nucleus physical phenomenon that helped the BB's range performance.

In order to let your review committee know more about the structure of the case and its possible effects, please follow the illustrations as follows: First, please refer to Figure 3, this is a barrel of a BB bomb toy gun. The structure includes a barrel 3, which is a hollow tube body, and has a filling end 31 and a striking end 32. The filling end 31 has a first duct 311, and the striking end 32 has a second pipe 321 , the first pipe 311 and the second pipe 321 are connected The shape of the second pipe 321 is larger than the inner diameter of the first pipe 311.

As shown in FIG. 4, in the implementation of the present invention, the filling end 31 of the barrel 3 is provided with a BB elastic cutting device 4, and the BB elastic cutting device 4 has at least one pressing member 41, and the pressing member 41 And protruding into the first pipe 311 of the filling end 31; another, a BB projectile 5 is disposed at the filling end 31 of the barrel 3, and passes through the BB projectile 5 to make a BB bomb 6 is fed into the filling end 31 of the barrel 3 and further fed into the BB elastic cutting device 4 in the filling end 31 for preliminary positioning; subsequently, the BB projectile 5 can be operated to generate high pressure gas, In turn, the BB bomb 6 is pushed instantaneously, and the BB bomb 6 is fired and moved to the front of the barrel 3, and the BB bomb 6 will be forced through the BB elastic cutting device 4; and the BB bomb 6 is passed through the BB elastic cutting device 4 When the member 41 is pressed, the pressing of the pressing member 41 will exert a force on the BB projectile 6, so that the BB projectile 6 forms a self-upward rotation, when the BB bomb 6 is self-filling the end 31 When the flight in the pipeline 311 is advanced, the gap between the BB bomb 6 and the first conduit 311 is still small, so most of the high pressure gas remains after the BB bomb 6; As shown, when the BB projectile 6 continues to advance into the second conduit 321 of the striker end 32, the inner diameter of the second conduit 321 is larger than the inner diameter of the first conduit 311, in other words, the wall of the second conduit 321 The gap with the BB projectile 6 will be enlarged, and the gap between the pipe wall of the second pipe 321 and the BB projectile 6 is enlarged, so that the BB projectile 6 is below the same displacement linear distance in the first pipe 311 and the second pipe 321, The number of collisions of the BB projectile 6 in the second pipe 321 will be smaller than that in the first pipe 311, and the frequency of the collision will also be reduced. Thus, the BB projectile 6 can be reduced in the process of the displacement of the second pipe 321 The energy loss caused by the collision, and the stability of the flight of the BB bomb 6 is improved; further, as shown in Fig. 6, since the gap between the wall of the second pipe 321 and the BB bomb 6 is enlarged, the second pipe is In 321 there will be more high-pressure gas quickly running to the front of the BB bomb 6, so that the atmosphere in the space ahead of the BB bomb 6 will be affected by the high-pressure gas passing through it, and the pressure in the space ahead of the BB bomb 6 will Being quickly and effectively reduced, which in turn produces a nucleus physics phenomenon, which contributes to the forward position of the BB bomb 6 The flight is shifted so that the BB 6 is completely off the barrel 3 and has a better range performance.

The function of the present invention is that the second duct 321 of the attack end 32 of the present barrel 3 is larger than the first duct 311 of the filling end 31, so that the BB bomb 6 can be made by the first duct 31. 1 After entering the second pipe 321, the number and frequency of collisions of the BB bomb 6 are reduced, and the energy loss of the forward flight of the BB bomb 6 caused by the collision can be reduced, and more high-pressure gas is run to the front of the BB bomb 6 In turn, the white nucleus physical phenomenon is generated, which helps the stability and range performance of the flight after the BB bomb 6 is fired.
