Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, and in particular to a protective cover for a tire temperature and pressure sensor. Background Technology
[0002] Tire failure is a major cause of sudden traffic accidents during high-speed driving, with abnormal tire pressure and temperature being the primary reasons for tire blowouts. Tire Pressure Monitoring Systems (TPMS) are mainly used to automatically monitor tire pressure and temperature in real time, issuing alarms when the tires are in an unsafe condition to remind the driver to take timely measures to ensure driving safety.
[0003] While external tire temperature and pressure sensors are easier to replace than internal ones, they still require removal of the sensor and locking nut each time the tire is inflated, making the process time-consuming. Utility Model Content
[0004] The purpose of this utility model is to provide a protective cover for a tire temperature and pressure sensor in order to solve the above-mentioned problems.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A protective sleeve for a tire temperature and pressure sensor includes a tire temperature and pressure sensor housing and a valve stem connector. The tire temperature and pressure sensor housing and the valve stem connector are fixedly connected together. The end of the valve stem connector away from the tire temperature and pressure sensor housing is connected to the tire valve stem. The lower end of the tire valve stem has a groove. A tapered backing member with a smaller upper part and a larger lower part is integrally connected to the upper part of the groove. A tapered backing member with a larger upper part and a smaller lower part is threadedly connected to the lower part of the groove. The lower end of the valve stem connector is slidably connected to a tenon that can be engaged in the groove. The end of the tenon away from the groove is fixedly connected to one end of a guide rod. The other end of the guide rod passes through the valve stem connector and is fixedly connected to a limiting block. A return spring is sleeved on the guide rod. One end of the return spring is fixedly connected to the tenon, and the other end of the return spring is fixedly connected to the valve stem connector.
[0007] As a further description of the above technical solution:
[0008] The lower end of the tire valve is provided with a cylindrical sealing section, and the upper end of the valve connector is a sealing connecting cylinder. The inner diameter of the sealing connecting cylinder is 1 mm larger than that of the cylindrical sealing section, and a sealing ring is installed on the inner wall of the sealing connecting cylinder.
[0009] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0010] The gas nozzle connector of this utility model has a quick-release structure. When the temperature and pressure monitoring device needs to be removed, simply rotate the conical return member to press the locking tenon back, and then pull out the gas nozzle connector to achieve quick removal of the temperature and pressure monitoring device. The quick-release structure of this protective sleeve improves the convenience of using the external temperature and pressure monitoring device. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0017] Example 1:
[0018] like Figure 1-4As shown, a protective sleeve for a tire temperature and pressure sensor includes a tire temperature and pressure detector housing 10 and a valve stem connector 2. The tire temperature and pressure detector housing 10 and the valve stem connector 2 are fixedly connected together. The end of the valve stem connector 2 away from the tire temperature and pressure detector housing 10 is connected to a tire valve 1. The lower end of the tire valve 1 has a groove. The upper part of the groove is integrally connected to a tapered return member 3 that is smaller at the top and larger at the bottom. The lower part of the groove is threadedly connected to a tapered return aid member 4 that is larger at the top and smaller at the bottom. The lower end of the valve stem connector 2 is slidably connected to a tenon 5 that can be engaged in the groove. The end of the tenon 5 away from the groove is fixedly connected to one end of a guide rod 7. The other end of the guide rod 7 passes through the valve stem connector 2 and is fixedly connected to a limiting block 8. A return spring 6 is sleeved on the guide rod 7. One end of the return spring 6 is fixedly connected to the tenon 5, and the other end of the return spring 6 is fixedly connected to the valve stem connector 2. When installing the tire temperature and pressure detector, first rotate the conical return member 4 downwards to the bottom of the slot, and then push the valve connector 2 onto the tire valve 1. At this time, the latch 5 pops out under the action of the return spring 6 and locks into the slot of the tire valve 1. When removing the tire temperature and pressure detector, first rotate the conical return member 4 upwards to the bottom of the slot. The conical return member 4 presses the latch 5 back, and then pull out the valve connector 2 to achieve quick removal of the temperature and pressure monitoring device.
[0019] As a further description of the above technical solution:
[0020] The lower end of the tire valve 1 is provided with a cylindrical sealing section, and the upper end of the valve connector 2 is sealed with a connecting cylinder. The inner diameter of the sealing connecting cylinder is 1 mm larger than that of the cylindrical sealing section. The inner wall of the sealing connecting cylinder is equipped with sealing rings 9, and the number of sealing rings 9 is not less than 3. Multiple sealing rings 9 are used to ensure the airtightness between the valve connector 2 and the tire valve 1.
[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
