Description

Technical Field

[0001] This utility model relates to the field of rubber sealing ring technology, specifically a one-way fixed waterproof rubber sealing ring. Background Technology

[0002] Headlights play a vital role in vehicle operation, providing illumination for the driver in low-light conditions. A headlight consists of a housing, inside which is the headlight body and a reflector located on the outside of the headlight body. Typically, the housing is directly connected and fixed to the headlight body via an adjustable fixing structure. However, this structure is not well-sealed, often resulting in water leakage. Water vapor can accumulate inside the headlight, leading to water ingress, and the headlight also has poor shock resistance.

[0003] Therefore, sealing is particularly important in the structure of car lights. During the assembly process, a sealing ring is usually used between the housing and the lamp body to achieve a waterproof effect. However, since the housing is mostly connected by screws, water can easily enter through the unavoidable gaps in the screw holes during long-term use, making it impossible to achieve a complete seal. Utility Model Content

[0004] The purpose of this invention is to provide a one-way fixed waterproof rubber sealing ring to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The present invention provides a one-way fixed waterproof rubber sealing ring, comprising a sealing ring, a fixing ring, and a waterproof ring. The sealing ring is provided with multiple sealing lips, the fixing ring is provided with multiple positioning holes, and the waterproof ring is provided with a waterproof pad corresponding to each positioning hole on the side near the fixing ring.

[0007] Furthermore, the sealing ring and the fixing ring have a T-shaped cross-section, the end of the sealing ring and the fixing ring have an R-angle, and the thickness of the sealing ring is greater than the thickness of the fixing ring.

[0008] Furthermore, the fixing ring has a first sealing surface and a second sealing surface, and the second sealing surface and the waterproof ring have a fan-shaped angle, the fan-shaped angle being less than 45 degrees.

[0009] Furthermore, the plurality of positioning holes are arranged at equal intervals with the fixing ring as the center, and the positioning holes are provided with anti-slip inner rings.

[0010] Furthermore, the outer diameter of the waterproof pad is consistent with the inner diameter of the positioning hole.

[0011] Furthermore, the waterproof ring is cone-shaped, and its end is connected to the fixing ring.

[0012] Beneficial effects: A one-way fixed waterproof rubber sealing ring adopts an integrated structure of sealing ring, fixing ring and waterproof ring to achieve a comprehensive sealing effect on the hole of the vehicle lamp body. It avoids the problem of corrosion in the gap of the locking screw hole due to inadequate waterproofing, which can cause the sealing ring to crack and affect the sealing effect, or cause the sealing ring and the rusted part of the locking screw to react chemically and stick together and be difficult to disassemble. It effectively ensures the sealing performance and extends the service life of the sealing ring. Attached Figure Description

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] Example

[0020] like Figure 1-3 As shown, a one-way fixed waterproof rubber sealing ring includes a sealing ring 1, a fixing ring 2 and a waterproof ring 3. The sealing ring 1 is provided with multiple sealing lips 4, the fixing ring 2 is provided with multiple positioning holes 5, and the waterproof ring 3 is provided with a waterproof pad 6 on the side near the fixing ring 2 that corresponds one-to-one with the positioning holes 5.

[0021] The sealing ring 1 and the fixing ring 2 have a T-shaped cross-section. The end of the sealing ring 1 and the fixing ring 2 have an R-angle. The thickness of the sealing ring 1 is greater than that of the fixing ring 1. The sealing ring 1 is partially inserted into the mounting hole of the vehicle lamp body, while the fixing ring 2 protrudes from the edge of the mounting hole of the vehicle lamp body. The fixing ring 2 has a first sealing surface 21 and a second sealing surface 22. The first sealing surface 21 is tightly fitted with the end face of the mounting hole of the vehicle lamp body, and the second sealing surface 22 is tightly fitted with the waterproof ring 3. There is a fan-shaped angle 7 between the second sealing surface 22 and the waterproof ring 3. The angle 7 is less than 45 degrees. After installation, the waterproof ring 3 is flush with the fixing ring 2 by compression, eliminating the fan-shaped angle 7.

[0022] Multiple positioning holes 5 are arranged at equal intervals with the fixing ring 2 as the center. The positioning holes 5 are equipped with anti-slip inner rings 8. After the sealing ring 1 is installed in place, it is screwed into the multiple positioning holes 5 with locking screws to fix the sealing ring as a whole. The outer diameter of the waterproof gasket 6 is the same as the inner diameter of the positioning hole 5. The waterproof ring 3 is conical in shape. The end of the waterproof ring 3 is connected to the fixing ring 2. After the fixing ring 2 is fixed with locking screws, the headlight body and the headlight housing are assembled together. The headlight housing presses the waterproof ring 3 against the fixing ring 2, so that the waterproof gasket 6 fits tightly against the positioning hole 5 to achieve a seal.

[0023] In this utility model, a fixing ring 2 is used to fix and install the vehicle lamp body, and a waterproof ring 3 is used to protect the mounting hole, so as to achieve a complete sealing effect on the mounting hole. This prevents the locking screw from rusting due to inadequate waterproofing, which could cause the sealing ring to crack and affect the sealing effect, or cause the sealing ring and the rusted part of the locking screw to react chemically and stick together, making them difficult to disassemble and affecting the service life of the sealing ring.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
