The waterproof protection component 22 is disposed on the outer wall of the rear end of the waterproof assembly component 21.
[0020] The waterproof assembly component 21 includes: a mating sealing joint 212, a sealing waterproof groove 213, a detonator core mating placement groove 211, a first mounting threaded sleeve 214, a sealing waterproof sleeve 216, an assembly positioning threaded sleeve 217, a signal line connector 219, a connecting lead 210, and a threaded assembly groove 218. The threaded assembly groove 218 is formed at both ends inside the assembly positioning threaded sleeve 217. The front end of the assembly positioning threaded sleeve 217 is installed at the rear end of the sealing waterproof sleeve 216. The front end of the sealing waterproof sleeve 216 is mated inside the sealing waterproof groove 213. The sealing waterproof groove 213 is formed inside the rear end of the mating sealing joint 212. The inner wall of the mating sealing joint 212 is installed on the outer wall of the rear end of the detonator housing 1. The detonator core mating placement groove 211 is formed inside the rear end of the detonator housing 1. The front end of the first mounting threaded sleeve 214 is installed at the rear end of the mating sealing joint 212. The front end of the connecting lead 210 is installed at the rear end of the signal line connector 219. The threaded assembly groove 218 is detachably installed on the outer wall of the first mounting threaded sleeve 214.
[0021] The waterproof protection component 22 includes: a rear limiting baffle 222, a sliding block 223, a second mounting threaded sleeve 224, an outer waterproof protective telescopic cover 221, and a front limiting block 225. The rear end of the front limiting block 225 is mounted on the outer wall of the front end of the sliding block 223. The front end of the rear limiting baffle 222 is mounted on the outer wall of the rear end of the sliding block 223. The inner wall of the rear limiting baffle 222 is mounted on the outer wall of the rear end of the signal line connector 219 and the outer wall of the front end of the connecting lead wire 210. The second mounting threaded sleeve 224 has a sliding groove inside and is movably mounted on the outer wall of the sliding block 223. The rear end of the outer waterproof protective telescopic cover 221 is rotatably mounted on the front end of the rear limiting baffle 222. The front end of the outer waterproof protective telescopic cover 221 is rotatably mounted on the outer wall of the rear end of the assembly positioning threaded sleeve 217. The inner wall of the assembly positioning threaded sleeve 217 is detachably mounted on the outer wall of the second mounting threaded sleeve 224. The size of the second mounting threaded sleeve 224 is compatible with the size of the first mounting threaded sleeve 214.
[0022] The specific implementation method is as follows: When using this utility model, the connecting lead 210 needs to be connected to the detonator core docking groove 211 through the sealing waterproof sleeve 216 set at the front end. After the detonator core docking groove 211 is connected, the front and rear ends of the second mounting threaded sleeve 224 and the first mounting threaded sleeve 214 are docked. After the second mounting threaded sleeve 224 and the first mounting threaded sleeve 214 are docked, the assembly positioning threaded sleeve 217 is rotated. The assembly positioning threaded sleeve 217 rotates forward to connect and position the second mounting threaded sleeve 224 and the first mounting threaded sleeve 214. When the assembly positioning threaded sleeve 217 rotates forward, the sealing waterproof sleeve 216 set at its front end moves into the groove. The sealing process is carried out inside the sealing waterproof groove 213. After the sealing waterproof groove 213 and the sealing waterproof sleeve 216 are sealed and connected, the initial waterproofing work is completed. When the assembly positioning threaded sleeve 217 rotates and moves forward, its rear end rotatably installed outer waterproof protective telescopic cover 221 rotates and extends to provide waterproof protection for the outer wall of the rear end of the waterproof assembly component 21. This device achieves the stability of the rear end installation and connection of the detonator shell 1 by rotating the sealing waterproof assembly work, avoiding the problem of unstable contact that may occur when the detonator shell 1 is used after the connection is completed, which would affect the use of the detonator shell 1. This component greatly improves the stability of the entire device in use and installation, and further improves the waterproof performance of the entire device.
[0023] The working principle of this utility model is as follows: When using this utility model, the connecting lead 210 needs to be connected to the detonator core docking groove 211 through the sealing waterproof sleeve 216 at the front end. After the detonator core docking groove 211 is connected, the second mounting threaded sleeve 224 and the first mounting threaded sleeve 214 are docked at their front and rear ends. After the second mounting threaded sleeve 224 and the first mounting threaded sleeve 214 are docked, the assembly positioning threaded sleeve 217 is rotated and moved forward to connect the second mounting threaded sleeve 224 and the first mounting threaded sleeve 214. 14. When the assembly positioning threaded sleeve 217 rotates forward, the sealing waterproof sleeve 216 at its front end moves into the sealing waterproof groove 213 to perform sealing work. When the sealing waterproof groove 213 and the sealing waterproof sleeve 216 complete the sealing docking, the initial waterproofing work is completed. When the assembly positioning threaded sleeve 217 rotates forward, the outer waterproof protective telescopic cover 221 that can be rotatably installed at its rear end rotates and extends to perform waterproof protection work on the outer wall of the rear end of the waterproof assembly component 21. This device achieves the stability of the installation docking of the rear end of the detonator shell 1 by rotating the sealing waterproof assembly work.
