[0018] Example

[0019] Please refer to Figure 1-Figure 2 The present invention proposes a locking valve TPMS installation structure and an assembly method thereof, comprising a valve core 1 and a pressure sensor 2. A tube body 3 is coaxially arranged at the air outlet end of the valve core 1. An annular groove 31 with a diameter smaller than the outer diameter of the tube body 3 is arranged on the outer side surface of the tube body 3. The pressure sensor 2 is provided with a ring buckle 21 which is sleeved over the tube body 3. A buckle 5 is installed on the annular groove 31 and the ring buckle 21 is restricted between the annular groove 31 and the valve core 1. In this scheme, the ring buckle 21 is arranged on the side of the pressure sensor 2, and the buckle 5 is a C-shaped buckle 5. When the ring buckle 21 is sleeved on the tube body 3, the buckle 5 is fixed corresponding to the annular groove 31, and the ring buckle 21 can be restricted between the end of the valve core 1 and the annular groove 31, and the ring buckle 21 can be restricted from falling off on the tube body 3, thereby achieving a quick fixing effect.

[0020] In a specific embodiment, refer to Figure 1 , Figure 2 The tube body 3 is radially provided with a locking hole 32 that penetrates into the tube body 3, and the side of the ring buckle 21 is provided with a hole 211 that penetrates radially. The ring buckle 21 is sleeved through the tube body 3 to align the hole 211 with the locking hole 32 and is inserted and locked by the lock buckle 4. In this solution, the entire sensor may rotate relative to the tube body 3. When the hole 211 and the locking hole 32 correspond to each other, the lock buckle 4 is clamped to lock the ring buckle 21 and the tube body 3. At this time, the ring buckle 21 will not rotate relative to the tube body 3, and can also limit the ring buckle 21 from sliding relative to the tube body 3.

[0021] In a specific embodiment, refer to Figure 1 , Figure 2The lock buckle 4 includes a connecting piece 41 and a locking piece 42, one end of the locking piece 42 is connected to one side of the connecting piece 41, and one end of the connecting piece 41 is hinged to one end of the buckle 5, and the connecting piece 41 can be flipped relative to the buckle 5; in this scheme, the lock buckle 4 is separated into a connecting piece 41 and a locking piece 42, wherein the locking piece 42 is used to lock the hole 211 and the locking hole 32, and can limit the rotation of the ring buckle 21 relative to the tube body 3, but the entire assembly may fall off with the rotation of the tire, so the locking piece 42 is connected to the buckle 5 through the connecting piece 41, which can limit the locking piece 42 from being separated from the hole 211 and the locking hole 32, thereby limiting the ring buckle 21, and further, the length of the ring buckle 21 is equal to or slightly less than the minimum distance between the locking piece 42 and the buckle 5, which can better limit the space for the ring buckle 21 to slide on the tube body 3 and improve stability.

[0022] In a specific embodiment, refer to Figure 1 , Figure 2 A barb 421 is provided at one end of the locking piece 42 away from the connecting piece 41. The locking piece 42 is inserted into the locking hole 32 so that the barb 421 is located in the tube body 3 and locked. The flip angle between the connecting piece 41 and the buckle 5 is 90 degrees. In this solution, in order to further enhance the stability of the locking piece 42 in the locking hole 32, when the locking piece 42 is inserted into the locking hole 32, the barb 421 can be hooked with the inner wall of the tube body 3, which can further reduce the locking piece 42 from being separated from the locking hole 32 and improve the stability.

[0023] Please refer to Figure 1-Figure 2 , an assembly method of a lock-type valve TPMS mounting structure, which is installed through the lock-type valve TPMS mounting structure, including the following steps: first, the ring buckle 21 of the pressure sensor 2 is sleeved with the tube body 3; then the pressure sensor 2 is rotated to align the lock hole 32 with the hole 211; then the lock piece 42 is inserted into the lock hole 32 from the hole 211, and the barb 421 is hung on the inner wall of the tube body 3; then the buckle 5 is turned over relative to the connecting piece 41 and is clamped and limited with the ring groove 31.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
