Embodiment 1
[0025] like Figure 1-6 A pneumatic ballistic shock wave therapy instrument with impact head buffer structure shown includes a handle shell 1, a projectile body 2, an impact head 3 and a shell front cover 4, and the shell front cover 4 is arranged at the front end of the handle shell 1, The impact head 3 is arranged in the shell front cover 4, the projectile body 3 is arranged in the trajectory of the handle shell 1, and is driven by compressed air to impact the impact head 3, and the impact head 3 is provided with a buffer structure, The buffer structure includes a buffer collar 5 and at least two first O-rings 6, the buffer collar 5 is sleeved on the impact head 3, and the buffer collar 5 is provided around the circumferential direction of the impact head 3 There are at least two first annular grooves 51 , and each first O-ring 6 is sleeved on each first annular groove 51 .
[0026] The motion process of present embodiment 1 is, as figure 1 As shown, the first step: the bu...
Embodiment 2
[0030] Further, such as figure 1 , figure 2 As shown, it also includes an adapter ring 7, the front cover of the shell 4 is connected to the front end of the handle shell 1 through the adapter ring 7, and one end of the buffer collar 5 is interference-fitted with the inside of the adapter ring 7, so that The other end of the buffer collar 5 is in interference fit with the inside of the shell front cover 4 .
[0031] Adopting the above technical solution further prevents the impact head 3 from rushing out of the shell front cover 4 due to inertia after being impacted by the bullet body 2 .
[0032] Further, such as Figure 3-5 As shown, the number of the first annular grooves 51 is two, and the two first annular grooves 51 are parallel to each other.
[0033] With this technical solution, the buffer collar 5 is divided into three-stage buffer structures because it has two first buffer grooves 51 parallel to each other. , to reduce the loss of shock wave energy transfer pro...
Embodiment 3
[0041] On the basis of Embodiment 1, the compressed air storage mechanism can also be improved. like figure 1 As shown, the handle housing 1 is also provided with a buffer air chamber 9 for storing compressed air, and the buffer air chamber 9 includes a first air chamber 91 and a second air chamber 92, and the first air chamber 91 and the second air chamber The chambers 92 communicate with each other through vent holes.
[0042] The use of two-stage buffer air chambers makes the storage capacity of compressed air more sufficient, and also makes the pressure of compressed air more stable.
