Description

Technical Field

[0001] The utility model relates to the technical field of tire technology, in particular to a tire pressure monitoring cap. Background Art

[0002] The Tire Pressure Monitoring Cap is a tool for measuring tire pressure in vehicles. It quickly confirms proper tire pressure, ensuring the safety of you, your family, and your friends. It provides a timely reminder to check tire pressure. If the transparent window is green, the vehicle is drivable. If it is yellow-green, the tires should be inflated to ensure normal operation. If it is yellow, red, or green, the tires should be checked immediately for safety. The existing tire pressure detection cap has the problem of air leakage, so the tire pressure monitoring cap disclosed in the Chinese utility model patent with authorization announcement number CN212267162U appeared. Although the protective cover can effectively seal the tire gas in the protective cover, thereby solving this safety hazard and effectively ensuring driving safety, the outer shell is sealed and fixed with a connecting cover, and the upper end of the connecting cover is sealed and installed with a protective cover. It can be seen that a connecting cover is needed, and a first through hole is also required to be opened at the upper end of the connecting cover. This will greatly increase the production cost, which is not conducive to mass production and will limit the promotion and application of large areas. It is necessary to make improvements to this phenomenon. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples. However, it should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0032] Example 1: See Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A tire pressure monitoring cap includes a main body 1 and a transparent protective cap 2 arranged on the main body 1, a blind hole 3 is formed between the main body 1 and the transparent protective cap 2, and a valve core top core 4 is arranged inside the main body 1 to slide axially along the main body 1, the valve core top core 4 divides the blind hole 3 into an inner chamber 31 and an outer chamber 32, a first pressure indicating block 5 and a second pressure indicating block 6 are arranged in the inner chamber 31, a reset member 7 is arranged between the first pressure indicating block 5 and the second pressure indicating block 6, the valve core top core 4 moves toward the first pressure indicating block 5 to cause the first pressure indicating block 5 to compress the reset member 7, thereby achieving the desired effect. The first pressure indicating block 5 gradually covers the second pressure indicating block 6, which is convenient for the user to see the first pressure indicating block 5 or the second pressure indicating block 6 through the transparent protective cap 2 to judge whether it is normal, and it is more convenient for the user to directly observe that under normal circumstances, the reset member 7 is in the initial state. When in use, the tire pressure monitoring cap is screwed and installed to the tire valve core. The valve core top core 4 is supported and moved toward the side of the first pressure indicating block 5. The reset member 7 is gradually compressed. Under the action of air pressure, the first pressure indicating block 5 gradually covers the second pressure indicating block 6. This can be judged as normal. When the reset member 7 is reset, the second pressure indicating block 6 will be exposed, indicating a leak.

[0033] Example 2: It can be explained based on Example 1, as shown in Figure 1 、 Figure 3 and Figure 5As shown, the first pressure indicating block 5 includes a bowl body 51 that is clearance-fitted with the inner chamber 31. A seat body 52 is provided on one end face of the bowl body 51. The seat body 52 contacts the valve core top core 4. The contact between the valve core top core 4 and the seat body 52 pushes the first pressure indicating block 5 to move to one side. Figure 7 As shown, in order to improve the sealing performance of the inner chamber 31 and better promote the movement of the first pressure indicating block 5, a sealing gasket 8 is sleeved on the seat body 52. ​​One end surface of the sealing gasket 8 contacts the valve core top core 4, and the other end surface of the sealing gasket 8 contacts the bowl body 51. This arrangement is more conducive to promoting the movement of the first pressure indicating block 5. To further explain, the outer wall of the bowl body 51 is displayed in green, which is convenient for users to directly observe.

[0034] Example 3: It can be explained based on Example 2, such as Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, the second pressure indicating block 6 and the groove in the bowl body 51 are clearance-matched, which is conducive to the first pressure indicating block 5 gradually covering the second pressure indicating block 6, and the outer wall of the second pressure indicating block 6 is displayed in red. Under normal circumstances, the reset member 7 is fully compressed. Under the action of air pressure, the first pressure indicating block 5 covers the second pressure indicating block 6, that is, the observation display is green, which is normal. The reset member 7 is elastically opened, and the second pressure indicating block 6 is exposed, that is, the observation display is red. The red color shows up, which means that the leakage is very serious. Further explanation, as Figure 6 As shown, the outer wall of the second pressure indicating block 6 displays a yellow area 61 and a red area 62. Under normal circumstances, the reset member 7 is fully compressed. Under the action of air pressure, the first pressure indicating block 5 covers the second pressure indicating block 6, that is, the observation display is green, indicating a normal state. The reset member 7 elastically opens, exposing the second pressure indicating block 6, that is, the observation display is the yellow area 61, which is in a low pressure (low pressure warning) state, and the immediate observation display is the red area 62, which is in a serious air leakage (low tire pressure) state.

[0035] Example 4: This can be explained based on Example 1, Example 2, or Example 3. Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, the valve core top core 4 includes a core body 41 that is provided with a clearance fit within the outer chamber 32. A protrusion 42 is provided on the core body 41. This arrangement is reasonable and facilitates implementation. Furthermore, a sealing ring 9 is provided on the protrusion 42. This arrangement improves the sealing effect and facilitates the movement of the valve core top core 4.

[0036] Example 5: This can be explained based on Example 1, Example 2, Example 3, or Example 4. Figure 1 and Figure 5 As shown, the reset member 7 is a spring, which is widely available and is more conducive to the automatic rebound of the first pressure indicating block 5 .

[0037] Example 6: It can be described on the basis of Example 1 or Example 2 or Example 3 or Example 4, the main body 1 and the transparent protective cap 2 are fixedly connected by threads or snap-fitting, which is convenient for disassembly and installation.

[0038] The standard parts used in this application document can all be purchased from the market, and the specific connection methods of each part adopt conventional means such as mature bolts and rivets in the existing technology, which will not be described in detail here.

[0039] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of the present utility model. Therefore, based on the innovative concept of the present utility model, changes and modifications to the embodiments described herein, or equivalent structural or process transformations made using the contents of the present utility model specification and drawings, and direct or indirect application of the above technical solutions to other related technical fields are all included in the scope of protection of the present utility model patent.
