Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined with Figures 1-5 This invention describes the anti-loosening fixing structure of a tire pressure monitoring sensor.

[0020] In one embodiment, a tire pressure monitoring sensor anti-loosening fixing structure includes: a tire body 100, with a valve stem 101 disposed inside the tire body 100; and a tire pressure sensor body 200, which is threadedly connected to the outer end of the valve stem 101. like Figure 2 , Figure 3, Figure 4 and Figure 5 As shown, the reinforcement mechanism 300 is disposed outside the valve stem 101 and is used to reinforce the tire pressure sensor body 200 installed at the end of the valve stem 101. The reinforcement mechanism 300 includes a fixing ring 304, which is fastened to the outside of the valve stem 101 by bolts. The tire pressure sensor body 200 is provided with a mounting block 301 on the side wall facing the valve stem 101. The side wall of the mounting block 301 is provided with two sets of inserts 302 with the center of the mounting block 301 as the axis. The inserts 302 are inserted into the slots 305 opened on the side wall of the fixing ring 304. The outer arc surfaces at the upper and lower ends of the fixing ring 304 are provided with auxiliary positioning components 307 for positioning the inserts 302 inserted into the slots 305. In this embodiment, during use, the retaining ring 304 is first placed on the end of the valve stem 101 near the wheel hub, and then the tire pressure sensor body 200 is tightened onto the valve stem 101. The position of the slot 305 provided on the side wall of the retaining ring 304 is adjusted so that the retaining ring 304 is placed on the outside of the insert block 302. Then, the retaining ring 304 is firmly clamped onto the outer arc surface of the valve stem 101 by bolts. Then, the auxiliary positioning component 307 is used to vertically reinforce the insert block 302 inserted into the slot 305 to prevent the tire pressure sensor body 200 from loosening. like Figure 3 , Figure 4 and Figure 5 As shown, the auxiliary positioning component 307 includes a fixed frame 306 and a movable plate 310. The fixed frame 306 is respectively disposed on the outer arc surface of the upper and lower ends of the fixed ring 304. The movable plate 310 is movably disposed inside the fixed frame 306. The movable plate 310 is provided with an insert strip 309 for positioning the insert block 302 on the inner wall of the fixed ring 304. The outer arc surface of the fixed ring 304 is provided with a storage hole 308. The outer arc surface of the insert block 302 is provided with a groove 303. The insert strip 309 passes through the storage hole 308 and is inserted into the groove 303 on the outer arc surface of the insert block 302 inside the slot 305. A return spring 311 is provided on the surface of the movable plate 310 facing the inner top surface of the fixed frame 306. The top end of the return spring 311 is fixedly connected to the inner top surface of the fixed frame 306. A tightening bolt 312 is threaded through the top end of the fixed frame 306. The bottom end of the tightening bolt 312 is in close contact with the surface of the movable plate 310. The insert 309 is stored inside the storage hole 308 under the action of the return spring 311, and the bottom end of the insert 309 is slidably connected to the surface of the insert block 302. In this embodiment, under normal conditions, the elastic force of the return spring 311 pulls the movable plate 310 so that the insert 309 on the inner wall of the movable plate 310 is placed inside the storage hole 308. The bottom end of the insert 309 is located inside the storage hole 308. When it is necessary to tighten the plug 302, the user uses a tool to screw the tightening bolt 312 clockwise. Its bottom end presses down on the movable plate 310. The movable plate 310 overcomes the elastic force of the return spring 311 and moves downward, thereby driving the insert 309 to pass through the storage hole 308 and insert into the groove 303 of the plug 302, thereby positioning the plug 302 so that it cannot be pulled out of the slot 305. During disassembly, simply unscrew the top bolt 312 in the reverse direction. Under the restoring force of the return spring 311, the movable plate 310 drives the insert 309 to be pulled out from the inside of the groove 303. Loosen the bolt of the fastening ring 304, and the insert 302 can be pulled out from the inside of the slot 305. like Figure 5 As shown, an anti-slip ring 313 is provided on the inner wall of the fixed ring 304 that contacts the outer arc surface of the valve 101. The anti-slip ring 313 is made of nitrile rubber. An abutment is provided at the bottom end of the tightening bolt 312 that contacts the surface of the movable plate 310. The abutment is made of soft rubber. In this embodiment, the anti-slip ring 313 is made of nitrile rubber. Nitrile rubber has excellent oil resistance, good elastic recovery and high coefficient of friction, which can provide huge static friction while protecting the surface of the metal valve 101 from scratches. Secondly, a soft rubber contact head is provided at the bottom of the tightening bolt 312. When the tightening bolt 312 is tightened, it can provide flexible contact pressure to avoid causing metal indentations on the surface of the movable plate 310. When the car is moving, the rubber contact head provides a certain damping effect to prevent the tightening bolt 312 from loosening spontaneously due to micro-vibration, thereby further improving the stability of the tightening bolt 312.

[0021] Working principle: Before use, first place the retaining ring 304 on the end of the valve stem 101 near the wheel hub, then screw the tire pressure sensor body 200 into the end of the valve stem 101. After the tire pressure sensor body 200 is installed, rotate the retaining ring 304 to align the slot 305 on the side wall of the retaining ring 304 with the insertion block 302 on the side wall of the mounting block 301 on the side wall of the tire pressure sensor body 200. Then, place the retaining ring 304 over the insertion block 302, and insert the insertion block 302 into the mounting block 302. After entering the interior of the groove 305, the worker first uses bolts to fix the retaining ring 304 to the outside of the valve stem 101, and then uses tools to tighten the tightening bolt 312, so that the bottom end of the tightening bolt 312 presses against the movable plate 310. The insert 309 at the bottom end of the movable plate 310 passes through the receiving hole 308 and is inserted into the groove 303 opened on the surface of the insert 302, thereby positioning the insert 302 and thus preventing the tire pressure sensor body 200 installed at the end of the valve stem 101 from loosening and reinforcing it.
