For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0021] Please refer to Figs. 1-4 The copper sheet self-firing mechanism in the embodiment of the present application mainly comprises a shell 1, a connecting thread 2, an air cavity 3, a push head 4, a steel ball 5, an O-ring 6, a reset spring 7, a movement inner cavity 8, a gas passage 9, a bottom end mounting cavity 10, a sealing ring 11 and a linkage head 12 and the like.

[0022] The shell 1 is the main part of the whole mechanism, and the movement inner cavity 8 is formed in the inside of the shell 1 for accommodating other moving parts. The connecting thread 2 is formed on the bottom end outer wall of the shell 1, which is convenient for connecting with other equipment or gas cylinder. A rubber ring is further arranged on the inner wall at the top end of the connecting thread 2, which is used to enhance the sealing property of the connection.

[0023] The connecting thread 2 is located at the bottom end of the shell 1, which is used to connect the copper sheet self-firing mechanism with the gas cylinder or other equipment together, so as to ensure that the mechanism can work normally.

[0024] Air cavity 3: open in the shell 1 located in the top of the movement inner cavity 8 outer wall, with gas channel 9 through connection. When the mechanism is triggered, the gas will enter the air cavity 9 into the gas channel 3, thereby pushing the push head 4 to move.

[0025] Push head 4: located in the top of the movement inner cavity 8 inner wall, its outer wall is fixedly connected with sealing ring 11, for ensuring that the push head 4 does not leak in the movement process. The bottom of push head 4 is provided with a bottom mounting cavity 10 for installing reset spring 7.

[0026] Steel ball 5: uniformly arranged between linkage head 12 and push head 4, when push head 4 is moved by gas pressure, it will squeeze steel ball 5, and make it move to the direction of linkage head 12.

[0027] O ring 6: fixedly connected to the outer wall of linkage head 12, for enhancing the sealing between linkage head 12 and shell 1, preventing gas leakage.

[0028] Reset spring 7: fixedly connected in the bottom mounting cavity 10, its bottom is fixedly connected with linkage head 12. When push head 4 is moved by gas pressure, reset spring 7 will push linkage head 12 and push head 4 to reset.

[0029] Movement inner cavity 8: is the main movement space inside the mechanism, for accommodating push head 4, linkage head 12 and other components, and allowing them to reciprocate.

[0030] Gas channel 9: open in the shell 1, through connection with air cavity 3. When the mechanism is triggered, the gas will enter the air cavity 3 through the gas channel 9, thereby pushing the push head 4 to move.

[0031] Bottom mounting cavity 10: open in the bottom of push head 4, for installing reset spring 7, and allowing reset spring 7 to stretch and contract.

[0032] Sealing ring 11: fixedly connected to the outer wall of push head 4, for enhancing the sealing between push head 4 and shell 1, preventing gas leakage.

[0033] Linkage head 12: located below push head 4, its top side wall is in contact with the bottom of push head 4. The top of linkage head 12 is also provided with a bearing platform for bearing steel ball 5. When push head 4 is moved by gas pressure, it will squeeze steel ball 5, and make it move to the direction of linkage head 12, thereby driving linkage head 12 to move.

[0034] The working principle of the utility model is:

[0035] Initial state: In the initial state of the copper-free self-firing mechanism, the push head 4 is located at the top of the movement inner cavity 8, the return spring 7 is in a compressed state, the linkage head 12 is located below the push head 4, and the steel balls 5 are evenly distributed between the linkage head 12 and the push head 4. At this time, the gas cavity 3 and the gas passage 9 are in a closed state, and no gas enters.

[0036] Triggering process: When external force (such as impact or pressure) acts on the mechanism, gas will enter the gas cavity 3 through the gas passage 9. As the gas continues to enter, the pressure in the gas cavity 3 gradually increases, thereby pushing the push head 4 to move downward. In the process of moving the push head 4, it will squeeze the steel balls 5 to move in the direction of the linkage head 12. At the same time, the return spring 7 also begins to gradually stretch.

[0037] Firing process: When the push head 4 moves to a certain position, it will trigger the firing mechanism of the mechanism. At this time, the steel balls 5 will completely fall into the carrying platform of the linkage head 12, thereby driving the linkage head 12 to move quickly. The movement of the linkage head 12 will further push other components (such as the gas release device in the gas cylinder) to work, realizing the blasting effect of the gas cylinder.

[0038] Resetting process: After the firing is completed, the return spring 7 will begin to contract, pushing the linkage head 12 and the push head 4 to reset to the initial state. At this time, the gas cavity 3 and the gas passage 9 are again in a closed state, waiting for the next triggering.

[0039] In summary, the copper-free self-firing mechanism adopts a more concise and reliable mechanical structure, abandoning the traditional copper sheet design. This makes the replacement and disassembly process of the product more simple and convenient, greatly reducing the operation difficulty and time cost of the user. At the same time, since it does not need to rely on the compression and fracture of the copper sheet to realize blasting, the mechanism has higher reliability and safety in assembly and use.
