Description

Technical Field

[0001] This utility model relates to the technical field of TPMS valve stems for automobile tires, and more specifically to a quick-connect fixed-angle valve stem. Background Technology

[0002] A TPMS (Tire Pressure Monitoring System) is a system that uses tire pressure sensors and monitoring units with wireless radio frequency communication to monitor tire pressure in real time. To achieve real-time monitoring, each tire is equipped with a TPMS transmitter, which monitors the tire pressure and temperature and transmits this data to a TPMS receiver inside the vehicle. To ensure the TPMS transmitters are securely mounted and will not fall off under various harsh driving conditions, they are typically mounted on the tire rim and fixed to the valve stem.

[0003] Most existing fixed-angle TPMS valves require two-stage installation. The first stage involves assembling the valve stem, gasket, and shim. The second stage requires assembling the transmitter, adjusting it according to the rim angle, and tightening it with screws. This assembly process is cumbersome and requires both screws and a torque wrench. Utility Model Content

[0024] 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 in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] See Figure 1 , Figure 4 A quick-connect fixed-angle valve includes a valve stem base 1, a valve stem 2, a spring 3, a locking block 4, and a transmitter housing 5. The locking block 4 is fixedly connected to one end of the valve stem 2 facing the transmitter housing 5, and the valve stem base 1 is fixedly connected to the other end of the valve stem 2 away from the transmitter housing 5. The diameter of the valve stem base 1 is larger than the diameter of the valve stem 2. The valve stem base 1 provides a support surface for one end of the spring 3. A spring 3 is provided on the outer side of the valve stem 2 between the valve stem base 1 and the locking block 4. A locking hole 8 adapted to the locking block 4 is provided on the transmitter housing 5. The locking block 4 can pass through the locking hole 8 and rotate so that the valve stem 2 or the valve stem base 1 is connected and fastened to the transmitter housing 5. In this embodiment, the valve stem 2 is connected to other structures of the valve through the valve stem base 1, and the transmitter housing 5 and the transmitter are an integral structure.

[0026] Locking block 4 can pass through lock hole 8 and rotate, so that the bottom of lock hole 8 limits the misaligned locking block 4. The spring force of spring 3 can make the mouth rod 2 connected and fastened to the transmitter housing 5 without the need for additional screws and special torque wrenches for connection and locking, which is convenient for disassembly and assembly.

[0027] See Figure 4 The transmitter housing 5 has a mounting groove 6 that matches the nozzle rod 2. The locking hole 8 passes through the mounting groove 6. The size of the mounting groove 6 matches the size of the nozzle rod 2, so that the nozzle rod 2 can extend into the mounting groove 6. In this embodiment, the size of the mounting groove 6 is slightly larger than the size of the nozzle rod 2, and the size of the locking block 4 is smaller than the size of the mounting groove 6, so that the locking block 4 can extend into the mounting groove 6 together with the nozzle rod 2. The size of the locking hole 8 matches the size of the locking block 4.

[0028] See Figure 2 , Figure 5 In this embodiment, a boss is fixedly connected to the transmitter housing 5, and multiple reinforcing ribs are provided at the connection end between the boss and the transmitter housing 5. The mounting groove 6 is opened on the boss, and the locking hole 8 passes through the boss.

[0029] To improve the stability of the lock block 4 after rotation, the bottom inner wall of the lock hole 8 has a certain thickness for the opening of the groove 7. The bottom outer wall of the lock hole 8 is provided with a groove 7 that matches the lock block 4. In this embodiment, the groove 7 is opened on the bottom outer wall of the mounting groove 6. The groove 7 and the lock hole 8 are offset. The angle between the groove 7 and the lock hole 8 is 60 degrees. Of course, it can also be other angles such as 15 degrees, 30 degrees, 45 degrees, etc.

[0030] See Figure 3 , Figure 4 If the locking block 4 is a triangular prism, then the locking hole 8 is a triangular hole. Of course, the locking block 4 can also be other shapes, such as a cuboid. The locking block 4 has plum blossom-shaped protrusions around its circumference. Correspondingly, the locking hole 8 is set as a rectangular hole and a plum blossom hole that matches the plum blossom-shaped protrusions.

[0031] How to use:

[0032] After the nozzle rod 2 is aligned with the locking hole 8 of the transmitter housing 5, it is inserted into the transmitter housing 5. The nozzle rod 2 is rotated 60 degrees, and the locking block 4 of the nozzle rod 2 is misaligned with the locking hole 8 of the transmitter housing 5, locking the transmitter housing 5, i.e., the transmitter. At this time, the spring 3 is axially compressed. One end of the spring 3 is pressed against the bottom end face of the nozzle rod base 1, and the other end is pressed against the top end face of the mounting groove 6 inside the transmitter housing 5. The transmitter housing 5 is subjected to the axial force of the spring 3 to fix the transmitter housing 5, nozzle rod 2, nozzle rod base 1. The groove 7 locks the locking block 4 and nozzle rod 2, so that the nozzle rod 2 cannot be moved radially or circumferentially, and the nozzle rod 2 is completely locked.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
