Description

Technical Field

[0001] This utility model relates to the field of LED street light technology, specifically to a sealing device for LED street light body that prevents rainwater leakage. Background Technology

[0002] With continuous innovation in LED technology, LEDs will replace traditional light sources and become more widespread. LED products can be more widely used in street lighting products. Therefore, the demand for waterproof structures for LED street lights, especially smart LED street lights in cities, is increasing. When using existing LED street lights, rainwater or moisture can enter through the connection between the lamp cover and the housing, affecting the internal components. Existing technologies also have the problem that moisture can easily enter through the openings in the posts.

[0003] In response, Chinese patent application number CN202320944047.8 discloses a waterproof structure for LED streetlights, including a light box containing an LED light panel assembly. The light box has a wire-passing hole on its wall, and a wire sleeve assembly is installed in the hole. The wire sleeve assembly includes a wire sleeve, a cap, and a sealing tube. The inner end of the wire sleeve is threaded into the wire-passing hole, and the sealing tube is inserted into the outer end of the wire sleeve. The sealing tube includes a tapered section with a larger inner end and a smaller outer end, and several slits are provided on the outer wall of the tapered section. The cap is fitted onto the tapered section, and the inner wall of the cap is a conical surface matching the outer wall of the tapered section. The cap is threaded onto the wire sleeve so that when the cap rotates, it compresses the tapered section, pressing the wires inside the tapered section tightly. Compared to existing technologies, this utility model's waterproof structure for LED streetlights improves the waterproof performance and safety of LED streetlights.

[0004] The device uses a cap that can be screwed onto the outside of a tapered tube section, causing the tapered tube section to deform and lock onto the outside of the wire, thus ensuring a seal between the wire and the wire sleeve assembly. However, the tapered tube section has slits, which create gaps on its surface. As a result, when the wire is attached, there is a gap between the tapered tube section and the wire, allowing water to enter the lamp body through the gap, causing the device to become damp and damaged.

[0005] Therefore, in order to solve the above problems, a sealing device for LED street light body that prevents rainwater leakage is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a sealing device for LED street light body that prevents rainwater leakage, in order to solve the problem mentioned in the background art where the device uses a cap that can be screwed onto the outside of a tapered tube section, causing the tapered tube section to deform and lock onto the outside of the wire to ensure the sealing between the wire and the wire sleeve assembly. However, the tapered tube section has slits, which create gaps on the surface of the tapered tube section. Consequently, when the wire is attached, there is a gap between the tapered tube section and the wire, through which water can enter the lamp body, causing the device to become damp and damaged.
