Description

Improved tire pressure detector fixed structure

The present invention relates to an improved tire pressure detector fixing structure, which is intended to make it easier for users to fix the tire pressure detector on the wheel rim.

Tire pressure is an important value for whether a vehicle can drive safely, and with the advancement of technology, the methods for detecting tire pressure have also improved a lot. Before going on the road, tire pressure could only be measured wheel by wheel manually, and now various methods are used to measure tire pressure. The electronic equipment automatically measures and transmits it to the monitoring screen for display, which is much more convenient, including electronic tire pressure detectors.

There are quite a few types of tire pressure detectors, and the more mainstream form is the style that includes a valve. Although this style has more steps in installation, it has the advantage of stable installation. For example, Taiwan patent The "improvement of the fixed structure of the tire pressure detector" presented in No. M555942, the general installation process requires operating the positioning piece to install the valve on the rim, and then operating the locking bolt to fix the angle of the body. The tire pressure detector is firmly fixed on the rim. However, because its body needs to be as close as possible to the corresponding surface of the rim, in order to make the data detection more accurate, it also makes the body located in the groove of the rim. Inside, the space for operating screws is greatly reduced, making installation inconvenient.

In view of this, it is necessary to simplify the installation steps of the tire pressure detector in the aforementioned form.

In order to improve the problems of conventional products, the present invention makes structural innovations to the fixing auxiliary ring, and utilizes the feature that its wide section and narrow section can respectively abut against the limiting convex wall and the extended convex portion. When the present invention is installed on By operating the locking piece when the rim is on the rim, the wide section and the narrow section can be pressed against the limiting convex wall and the extension convex part respectively, thereby fixing the air nozzle to the rim and the installation angle of the fixed body at the same time. Compared with Xinzhi's product eliminates the need to tighten the bolts, thus simplifying the installation process.

In order to achieve the above objectives and effects, the present invention provides an improved tire pressure detector fixed structure, which includes: a main body with a positioning groove on one side, and two limiting protruding walls respectively located on the two side walls corresponding to the positioning groove. A limiting groove is formed between the two limiting convex walls; an air nozzle includes a pipe body, and two sides of one end of the pipe body respectively have an extending convex part, and each extending convex part is located in the positioning groove and cannot pass through the positioning groove. a limiting groove, the pipe body partially penetrates the limiting groove; a fixed auxiliary ring, which includes a connected wide section and a narrow section, the narrow section is movable through the limiting groove, and the narrow section is movable against Relying on each extending convex portion, the wide section movablely abuts each limiting convex wall, the tube body part passes through the fixing auxiliary ring; an airtight ring, the tube body part passes through the airtight ring; and a locking piece , which is arranged on the pipe body, and the airtight ring is located between the fixing auxiliary ring and the locking member.

In order to understand the implementation of the present invention in more detail, please also view it with the figures. As shown in the first to third figures, the present invention is an improved fixed structure of a tire pressure detector, which includes: a main body 1, There is a positioning groove 11 on one side, and two limiting protruding walls 111 are respectively located on the two side walls corresponding to the positioning groove 11. A limiting groove 1112 is formed between the two limiting protruding walls 111; an air nozzle 2 includes a tube. The body 21 has an extending protrusion 22 on both sides of one end of the tube body 21. Each extending protrusion 22 is located in the positioning groove 11 and cannot pass through the limiting groove 1112. The tube body 21 is partially penetrated in the limiting groove. 1112; A fixed auxiliary ring 3, which includes a connected wide section 31 and a narrow section 32. The narrow section 32 is movable through the limiting groove 1112, and the narrow section 32 is movable against each extending protrusion 22. , the wide section 31 moves against each limiting convex wall 111, the tube body 21 partially penetrates the fixed auxiliary ring 3; an airtight ring 4, the tube body 21 partially penetrates the airtight ring 4; and a lock The fastener 5 is provided on the tube body 21 , and the airtight ring 4 is located between the fixing auxiliary ring 3 and the fastener 5 .

Continuing with the above content, the embodiments of the present invention are further described in detail. When the locking member 5 of the present invention is not locked, the main body 1 can pivot relative to the air nozzle 2 to adjust the angle. The steps of installing the present invention on the wheel rim 100 are as follows. As shown in Figures 4 and 5, after inserting the air nozzle 2 into the corresponding position, the installation of the present invention can be completed by simply locking the locking member 5. The principle is that the airtight ring 4 of the present invention is locked after the locking member 5 is locked. , the airtight ring 4 will clamp the rim 100 with the fastener 5 to position the air nozzle 2 on the rim 100. In addition, its wide section 31 and narrow section 32 can be used to resist the limiting convex wall 111 and the extending convex portion respectively. 22 (see Figures 3 to 3A for details), when the fastener 5 is locked, the airtight ring 4 will press against the fixing auxiliary ring 3, so that the wide section 31 and the narrow section 32 of the fixing auxiliary ring 3 press against each other respectively. It resists the limiting convex wall 111 and the extending convex portion 22. In this way, each extending convex portion 22 will clamp the corresponding limiting convex wall 111 with the wide section 31. In addition, the narrow section 32 penetrating into the limiting groove 1112 is The pressing force of each extending protrusion 22 will make it impossible for the main body 1 to pivot relative to the air nozzle 2 to fix its angle. From this, it can be seen that during the installation process of the present invention, it is only necessary to lock the fastener 5, and the locking member 5 can be locked at the same time. The installation angle of the valve 2 being fixed on the wheel rim 100 and the fixing body 1 does not require bolts to fix the angle after the valve is fixed as in conventional products, which is novel and progressive.

As shown in the sixth figure, the wide section 31 and the narrow section 32 of the fixed auxiliary ring 3 have anti-slip grooves 33 on the side facing the main body 1. In this embodiment, the anti-slip grooves 33 are in the form of protrusions. In fact, the design can be changed according to the needs. Its structural advantage is that the wide section 31 and the narrow section 32 of the fixed auxiliary ring 3 are more stable when pressed against the corresponding parts.

As shown in the seventh figure, the part where the two limiting protruding walls 111 and the wide section 31 are movable against each other has at least one plane 1111. This embodiment takes a plurality of planes 1111 as an example. This structure has the advantage of The design of the flat surface 1111 can increase the contact area between the limiting convex wall 111 and the wide section 31 to improve the stability of the contact.

As shown in the third figure, the extending protrusions 22 move against the narrow section 32 to form an arc shape.

As shown in Figure 9, each of the extending protrusions 22 moves against the narrow section 32 (see the third figure for how the extending protrusions 22 move against the narrow section 32), showing a vertebra-like appearance.

As shown in the eighth figure, the main body 1 has a wheel-catching side 12. The two limiting protruding walls 111 are away from one end of the wheel-catching side 12 (the place circled by A in the figure). 12 is thicker. The advantage of this structure is that it can prevent the valve 2 and the narrow section 32 from being separated from the opening of the limiting groove 1112.

As shown in Figure 8A, one end of the limiting groove 1112 adjacent to the wheel side 12 is arc-shaped. Since the narrow section 32 will penetrate into the limiting groove 1112, one end of the limiting groove 1112 can be arc-shaped. It is more consistent with the appearance of the narrow section 32.
