DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a temperature sensor for coal mines with a protective structure, comprising an outer shell 1, an anti-collision plate 2 is slidably connected inside the outer shell 1, a slide rod 3 is slidably connected inside the anti-collision plate 2, one end of the slide rod 3 is fixedly connected to the outer wall of the outer shell 1, and the other end of the slide rod 3 is fixedly connected to a stopper 4, a buffer spring 5 is sleeved on the outer wall of the slide rod 3, one end of the buffer spring 5 is fixedly connected to the outer wall of the outer shell 1, and the other end of the buffer spring 5 is fixedly connected to the inner wall of the anti-collision plate 2, the outer wall of the outer shell 1 is fixedly connected to a fixed block 6, and the fixed block 6 is slidably connected to a spring sheet 7, The outer wall of the spring sheet 7 is fixedly connected with a telescopic rod 1 8, and the outer wall of the telescopic rod 1 8 is sleeved with a buffer spring 2 9, one end of the buffer spring 2 9 is fixedly connected to the outer wall of the spring sheet 7, and the other end of the buffer spring 2 9 is fixedly connected to the outer wall of the outer shell 1, one end of the spring sheet 7 is fixedly connected with a telescopic rod 2 10, and the outer wall of the telescopic rod 2 10 is provided with a buffer assembly, and the buffer assembly includes a buffer spring 3 11, and the outer wall of the buffer spring 3 11 is sleeved on the outer wall of the telescopic rod 2 10, one end of the buffer spring 3 11 is fixedly connected to one end of the spring sheet 7, and the other end of the buffer spring 3 11 is fixedly connected to the inner wall of the fixed block 6;
[0026] Specifically, when external pressure acts on the temperature sensor housing 1, the legs of the anti-collision plate 2 will be displaced in the internal space of the housing 1, and at the same time act on the buffer spring 1 5 and the spring sheet 7 to apply pressure. The buffer spring 1 5, when subjected to external force, will shrink along the outer wall of the slide rod 3, which can effectively absorb and disperse the external force, thereby playing a role in buffering the external impact force. At the same time, the stopper 4 at one end of the slide rod 3 plays a key role, effectively preventing the anti-collision plate 2 from falling off when subjected to external force, thereby increasing the stability of the entire structure. On the other hand, when the spring sheet 7 is subjected to pressure, it will deform, causing its two ends to move in the internal space of the fixed block 6, exerting additional pressure on the buffer spring 2 9 and the buffer spring 3 11, and shrinking them accordingly. The thrust generated by the buffer spring 2 9 and the buffer spring 3 11 during the shrinkage process, together with the shrinkage force of the buffer spring 1 5, forms a multiple buffer, further enhancing the buffering effect of the external force, thereby effectively protecting the housing 1 from damage, effectively protecting the temperature sensor housing 1 from damage by external pressure, and improving its stability and service life.
[0027] Reference Figure 1 , Figure 4 and Figure 5 The bottom of the outer shell 1 is fixedly connected with a mounting plate 12, the interior of the mounting plate 12 is fixedly connected with a positioning sleeve 13, the interior of the positioning sleeve 13 is fixedly connected with a bearing 14, the interior of the bearing 14 is fixedly connected with a screw 15, the outer wall of the screw 15 is rotatably connected to the interior of the positioning sleeve 13, one end of the screw 15 is fixedly connected with a handle 16, the outer wall of the screw 15 is threadedly connected with a slider 17, the outer wall of the slider 17 is slidably connected to the inner wall of the positioning sleeve 13, the interior of the positioning sleeve 13 is slidably connected with a clamping block 18, the bottom of the positioning sleeve 13 is fixedly connected with a limiting block 19, the outer wall of the clamping block 18 is fixedly connected with a telescopic shaft 20, one end of the telescopic shaft 20 is fixedly connected to the interior of the limiting block 19, the outer wall of the telescopic shaft 20 is sleeved with a telescopic spring 21, one end of the telescopic spring 21 is fixedly connected to the outer wall of the clamping block 18, and the telescopic spring 21 is fixedly connected to the interior of the limiting block 19;
[0028] Specifically, when the driving handle 16 starts to work, its rotating action will drive the screw 15 to rotate smoothly in the positioning sleeve 13 under the support of the bearing 14. The rotation of the screw 15 further pushes the slider 17 to slide accurately inside the positioning sleeve 13. The protruding block on the outer wall of the slider 17 fits with the inside of the positioning sleeve 13 to ensure that the slider 17 can move stably and smoothly along the outer wall of the screw 15. As the slider 17 moves, its displacement directly acts on the block 18, so that it can slide smoothly between the positioning sleeve 13 and the mounting piece, thereby achieving a stable installation of the temperature sensor. The installation process of the temperature sensor becomes simple and efficient, and the overall work efficiency is improved. When the temperature sensor needs to be disassembled or reinstalled, the block 18 can be easily moved by rotating the handle 16 in the opposite direction. At this time, the elastic force of the telescopic spring 21 will play a key role, which will pull the block 18 back into the positioning sleeve 13, making the entire disassembly process easy and convenient.
[0029] Working principle: when the temperature sensor for coal mines is needed, when the outer shell 1 of the temperature sensor is subjected to external pressure, the legs of the anti-collision plate 2 will move inside the outer shell 1, which will exert pressure on the buffer spring 1 5 and the spring sheet 7. After being subjected to pressure, the buffer spring 1 5 will shrink along the outer wall of the slide bar 3, thereby playing a role in buffering the external force. At the same time, the stopper 4 at one end of the slide bar 3 can effectively prevent the anti-collision plate 2 from falling off. In addition, when the spring sheet 7 is subjected to pressure, it will deform, and its two ends will move inside the fixed block 6, exerting pressure on the buffer spring 2 9 and the buffer spring 3 11, causing them to shrink as well. The thrust generated when the buffer spring 2 9 and the buffer spring 3 11 shrinks, together with the buffer spring 1 5, further strengthens the buffering effect against external force, thereby protecting the outer shell 1 from damage.
[0030] In addition, by driving the handle 16, the screw 15 is driven to rotate in the positioning sleeve 13 under the support of the bearing 14, thereby pushing the slider 17 to slide in the positioning sleeve 13, and the raised block on the outer wall of the slider 17 interacts with the inner wall of the positioning sleeve 13 to ensure that the slider 17 can move smoothly along the outer wall of the screw 15. The displacement of the slider 17 further acts on the block 18 to make it slide between the positioning sleeve 13 and the mounting part, thereby achieving a stable installation of the temperature sensor. Subsequently, by rotating the handle 16 in the opposite direction, the block 18 is pulled back into the positioning sleeve 13 by the elastic force of the telescopic spring 21, which simplifies the assembly and disassembly process of the temperature sensor and improves the operating efficiency.
