Description

Technical Field

[0001] This utility model discloses a waterproof rubber sealing ring structure and its application structure, belonging to the field of sealing ring technology. Background Technology

[0002] Sealing rings are widely used in various industries as common mechanical parts. Among them, waterproof sealing rings for lighting fixtures are used to install electrical wires. For lighting fixtures that are constantly exposed to humid environments, the waterproof performance of the sealing ring is crucial to the performance of the fixture. In the prior art, such as the utility model with publication number CN208720182U, a sealing ring structure is disclosed, including an outer ring with a sealing ring at its center. An electrical wire passes through the sealing ring and fits tightly against the outer wall of the wire. The outer edge of the outer ring has a first and second annular flange, and an annular groove is formed between the first and second flanges. A fixing plate is inserted into the groove. During implementation, dust and debris may enter the sealing ring as the wire passes through it, reducing the sealing performance of the sealing ring. Utility Model Content

[0003] In view of the above-mentioned shortcomings in the prior art, the present invention provides a waterproof rubber sealing ring structure and its application structure to solve the problems in the background art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A waterproof rubber sealing ring structure and its application structure include an outer ring, a sealing ring is provided at the center of the outer ring, an electric wire is sleeved on the inner wall of the sealing ring and is tightly attached to the outer wall of the electric wire; the outer edge of the outer ring is provided with a first flange and a second flange in an annular shape, and an annular groove is formed between the first flange and the second flange, and a fixing plate is inserted into the groove. Furthermore, the inlet end of the outer side of the sealing ring is provided with an annular dust removal component, the dust removal component includes an annular mounting seat, the annular mounting seat is connected to the annular groove two on the inner side of the outer ring, and the inner wall of the annular mounting seat is provided with two rows of bristles; the outer side of the outer ring is provided with an annular groove three, and the annular groove three is snapped together with the flow guide dust collection cover.

[0005] Furthermore, the bottom end of the second groove is provided with four limiting posts arranged in a ring, and the mounting base is provided with limiting holes corresponding to the limiting posts.

[0006] Furthermore, the brush bristles include upper bristles and lower bristles. The top of the upper bristles touches the wire and forms an angle of 15° with the inner wall of the mounting base. The lower bristles touch the wire and are set perpendicular to the inner wall of the mounting base.

[0007] Furthermore, the bottom end of the flow-guiding dust collection hood is provided with an inward buckle, the top of the flow-guiding dust collection hood is provided with a boss, the right side of the boss is provided with a dust collection chamber, and the right side of the dust collection chamber is provided with an inclined plate perpendicular to the bristles, which guides the dust on the bristles to fall into the dust collection chamber; the bottom surface of the boss abuts against the top surface of the mounting base, restricting the vertical displacement of the mounting base.

[0008] Furthermore, a wave-shaped buffer block is provided at the connection between the first flange and the second flange. There are a total of six buffer blocks distributed in a ring. The elastic deformation of the buffer block absorbs radial stress and avoids fatigue cracking.

[0009] Furthermore, the lower surface of the first flange is provided with hemispherical protrusions, a total of six protrusions distributed in a ring, and the protrusions abut against the fixing plate.

[0010] Furthermore, the outer ring and the sealing ring are integrally formed and are made of rubber.

[0011] Compared with the prior art, this utility model has the following advantages: The interlaced bristles of the annular dust removal component, combined with the flow-guiding dust collection hood, effectively clean and collect dust from the surface of the wires, preventing dust from entering the contact area between the sealing ring and the wires. Combined with the dust collection bin, this significantly improves the dustproof capability of the sealing ring and reduces the risk of seal failure due to dust accumulation. The corrugated buffer block absorbs the deformation energy generated by the sealing structure during implementation, thus preventing rubber cracking due to fatigue from affecting the sealing performance.

[0012] The modular design, achieved through the snap-fit ​​connection of the annular dust removal components and the flow-guiding dust collection hood, allows for disassembly and reuse after use, reducing production costs. Attached Figure Description
