[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up a reinforcement mechanism, after installation, the C-shaped buckle can be inserted into the two slots. Under the action of the two trapezoidal blocks, the connecting shaft and the second slider will apply tension to the first spring through the first slider, causing it to undergo elastic deformation and generate elastic force. Under the action of this elastic force, the second slider and the second slot will be tightened. Under the action of the C-shaped buckle, the tension generated during tightening will be converted into the extrusion force between the two sealing gaskets, thereby achieving a seal.

[0016] 2. By setting up an anti-fall-off mechanism, when the C-shaped buckle is inserted into slot one, the trapezoidal block will apply pressure to slider three, causing it to slide into slot four, thereby applying pressure to spring two, causing it to undergo elastic deformation and generate elastic force. When the C-shaped buckle is fully inserted into slot one, the elastic force will cause slider three to lock into slot three, thus locking the C-shaped buckle under the action of slider three. This can fix the reinforcement device, preventing it from falling off during use, enhancing the stability of the structure, and ensuring that the device maintains a good working condition during use.

A U-shaped buckle 203 is slidably connected to the inner walls of the two slots 201. Two trapezoidal blocks 204 are fixedly connected to the side of the U-shaped buckle 203 near the base 1. Sliding sliders 205 are slidably connected to the inner walls of the two slots 201, and the two trapezoidal blocks 204 are respectively compatible with the two sliding sliders 205. Several slots 206 are provided on the inner walls of the two slots 201 that are close to each other. Sliding blocks 207 are slidably connected to the slots 206. Connecting shafts 208 are fixedly connected to the upper sliding blocks 207 near the protector 101 and the lower sliding blocks 207 near the base 1. Springs 209 are sleeved on the outer walls of the connecting shafts 208. The springs 209 are fixedly connected to the sliding blocks 207 on the side close to them and to the inner walls of the slots 206 on the side away from them. By setting up a reinforcement mechanism, the device can be reinforced to prevent loosening and gaps from appearing as the device is used over time, thus ensuring that the nitrogen in the device does not interact with the air.

[0028] The anti-detachment mechanism 3 includes a groove 301 formed on the U-shaped buckle 203. A groove 4 302 is formed on the inner wall of the groove 201 away from the sealing gasket 202. A slider 303 is slidably connected to the inner wall of the groove 4 302. A spring telescopic rod 304 is fixedly connected to the inner wall of the groove 4 302 away from the sealing gasket 202. The side of the spring telescopic rod 304 near the slider 303 is fixedly connected to the slider 303. A spring 2 305 is sleeved on the outer wall of the spring telescopic rod 304. The side of the spring 2 305 away from the slider 303 is fixedly connected to the inner wall of the groove 4 302.

[0029] A specific application of this embodiment is as follows: First, move each component of the device to its corresponding position. Then, move the protector 101 onto the base 1. The protector 101 is an E97 product manufactured by Ningbo Youxin Electric Co., Ltd., which uses the action characteristics of a bimetallic strip as its working principle. Next, insert the bolt 102 into the protector 101 and fit the two sealing washers 202 together. The sealing washers 202 are made of fluororubber. Then, put the nut 103 onto the bolt 102 to fix the device. The bolt 102 and nut 103 are M5×8 and conform to GB / T41-2000. After installation, insert the C-shaped buckle 203 into the two slots 201. Under the action of the two trapezoidal blocks 204, and under the action of the connecting shaft 208 and the second slider 207, the spring 209 is pulled through the slider 205. The force causes the spring 205 to undergo elastic deformation and generate elastic force. Under the action of this elastic force, the slider 207 and the slot 206 are tightened. Under the action of the C-shaped buckle 203, the tension generated during tightening is converted into the compressive force between the two sealing gaskets 202, thereby achieving a seal. When the C-shaped buckle 203 is inserted into the slot 1 201, the trapezoidal block 204 applies pressure to the slider 303, causing it to slide into the slot 4 302, thereby applying pressure to the spring 2 305, causing it to undergo elastic deformation and generate elastic force. When the C-shaped buckle 203 is fully inserted into the slot 1 201, the elastic force causes the slider 303 to be locked into the slot 3 301, thereby locking the C-shaped buckle 203 under the action of the slider 303. After all this is completed, the oxygen in the device can be extracted and nitrogen injected through the inflation valve on the protector 101.
