[0028] Example 1
[0029] Reference Figures 1 to 3 This is the first embodiment of the present invention, which provides a break-resistant built-in ignition needle, comprising:
[0030] An electrode needle 100 is fixedly connected to an insulating layer 101 on its outer surface, and a spring 103 is provided on the outer surface of the insulating layer 101.
[0031] The outer shell mechanism 200 is disposed on the outer surface of the electrode needle 100 to protect the electrode needle 100. The outer shell mechanism 200 is provided with a protective shell 201 and a ceramic protective layer 204. An auxiliary adjustment component 203 is disposed on the outer surface of the protective shell 201, and the electrode needle 100 is disposed inside the ceramic protective layer 204.
[0032] Specifically, the insulating layer 101 can reduce the direct contact between the spring 103 and the electrode needle 100, and the insulating layer 101 does not completely cover the electrode needle 100, leaving its upper end exposed, thus maintaining the effectiveness of the electrode needle 100.
[0033] When in use, the ignition needle is installed in a suitable position using the auxiliary adjustment component 203. When the device is impacted, the auxiliary adjustment component 203, the ceramic protective layer 204, and the protective shell 201 will form multiple protections. If the impact force is high, the electrode needle 100 will slide downward. After the impact force leaves, the spring 103 will push the electrode needle 100 back to its original position.
[0034] Example 2
[0035] Reference Figures 2 to 3 This is the second embodiment of the present invention. Unlike the previous embodiment, the two ends of the spring 103 are respectively fixedly connected to a first fixing ring 102 and a second fixing ring 104. The inside of the first fixing ring 102 is fixedly connected to the upper part of the outer surface of the insulating layer 101, and the outer surface of the second fixing ring 104 is fixedly connected to the lower part of the inner wall of the ceramic protective layer 204.
[0036] Specifically, the first fixing ring 102 and the second fixing ring 104 can compress the spring 103 when the electrode needle 100 moves downward, and at the same time, the thrust of the spring 103 can be transmitted to the electrode needle 100.
[0037] The electrode needle 100 has a connecting needle 105 fixedly connected to its lower end. The connecting needle 105 is used for power connection and extends outside the protective shell 201. Both ends of the ceramic protective layer 204 are fixedly connected to sealing heads 205. The upper end of the electrode needle 100 passes through the sealing head 205, and the lower end of the sealing head 205 is fixedly connected to a corrugated sleeve 206. The sealing heads 205 are fixedly connected to both ends of the protective shell 201. The corrugated sleeve 206 is located on the outer surface of the connecting needle 105, and a fixing nut 207 is rotatably connected to its lower end. The outer surface of the protective shell 201 has a threaded groove 202. The protective shell 201 is made of high-temperature and corrosion-resistant material and is hollow. The outer surface of the ceramic protective layer 204 is fixedly connected to the interior of the protective shell 201.
[0038] Specifically, before use, the connecting wire is connected to the connecting pin 105 and fixed with the fixing nut 207. The corrugated sleeve 206 is telescopic and made of high temperature and corrosion resistant material. When the electrode pin 100 moves downward, the corrugated sleeve 206 can extend accordingly to keep the connection safe.
[0039] Furthermore, the auxiliary adjustment component 203 includes a threaded sleeve 2031. The interior of the threaded sleeve 2031 is threadedly connected to the upper part of the outer surface of the protective shell 201 via a threaded groove 202. An adjusting nut 2032 is provided at the lower end of the threaded sleeve 2031, and the adjusting nut 2032 is threadedly connected to the lower part of the outer surface of the protective shell 201 via the threaded groove 202. Clamping plates 2033 are fixedly connected to the opposite ends of both the threaded sleeve 2031 and the adjusting nut 2032. Both the threaded sleeve 2031 and the adjusting nut 2032 are hexagonal in shape.
[0040] Specifically, the threaded sleeve 2031 and the adjusting nut 2032 can both be disassembled separately through the threaded groove 202. During installation, the height position of the threaded sleeve 2031 can be selected, and the adjusting nut 2032 can be rotated to bring them closer together to fix the device in the installation position. Thus, the electrode needle 100 can be adjusted in height for easy installation on different equipment.
[0041] During use, the device is first placed in the installation position. Then, the position of the threaded sleeve 2031 on the protective shell 201 is adjusted according to the equipment. Then, the adjusting nut 2032 is rotated to move it closer to the threaded sleeve 2031. The device can then be fixed by the clamping plate 2033. When the device is subjected to lateral impact, the threaded sleeve 2031, the ceramic protective layer 204 and the protective shell 201 will form multiple protections to reduce the impact force on the electrode needle 100. If the impact force is high, the electrode needle 100 will slide downward. Then, the electrode needle 100 will drive the first fixing ring 102 to compress the spring 103. After the impact force leaves, the spring 103 will push the first fixing ring 102 to push the electrode needle 100 back to its original position, thus achieving the protection effect of preventing the ignition needle from breaking.
[0042] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.
[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
