[0001] This utility model relates to a waterproof structure for LED lamps, belonging to the field of lighting technology. Background Technology

[0002] The basic structure of an LED is an electroluminescent semiconductor chip, which is fixed to a support with silver or white glue. Then, silver or gold wires are used to connect the chip and the circuit board. Finally, the chip is sealed with epoxy resin to protect the internal core wires. LED streetlights are streetlights made with LED light sources. They have unique advantages such as high efficiency, safety, energy saving, environmental protection, long life, fast response speed, and high color rendering index, and are of great significance to energy saving in urban lighting.

[0003] However, LED streetlights will be damaged if left outdoors for a long time. When repairing LED streetlights, the screws on the LED streetlights need to be removed, which results in a long repair time.

[0004] This utility model proposes a new solution to the above problems. Utility Model Content

[0005] The main purpose of this utility model is to solve the problem that the maintenance of LED streetlights requires the removal of screws, which leads to long maintenance time, and provides a waterproof structure for LED lighting fixtures.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A waterproof structure for an LED lamp includes a housing, a sealing plate, and a connecting mechanism disposed on the housing. The connecting mechanism includes a mounting plate, a connecting tube fixedly connected to the lower surface of the mounting plate, a connecting rod slidably connected to the inner wall of the connecting tube, a limit plate fixedly connected to one end of the connecting rod, the inner wall of the connecting tube slidably connected to the limit plate, and a spring disposed inside the connecting tube and below the limit plate.

[0008] Preferably, one end of the connecting rod is rotatably connected to a fixing plate, and an insert plate is fixedly connected to the surface of the fixing plate.

[0009] Preferably, the lower surface of the sealing plate has a slot, and the inner wall of the slot is inserted into the insert plate.

[0010] Preferably, an anti-slip pad is fixedly connected to the upper surface of the insert plate, and the shape of the anti-slip pad is adapted to the slot.

[0011] Preferably, a sealing gasket is fixedly connected to the upper surface of the sealing plate, and an elastic gasket is fixedly connected to the surface of the sealing gasket.

[0012] Preferably, a sealing groove is formed on the upper surface of the outer shell, and the inner wall of the sealing groove is inserted into the elastic pad.

[0013] Preferably, an LED light panel is embedded on the lower surface of the sealing plate, and a protective film is pasted on the lower surface of the LED light panel.

[0014] Preferably, the upper surface of the outer casing is provided with equally spaced heat dissipation grooves, and heat dissipation fins are fixedly connected to the inner wall of the heat dissipation grooves.

[0015] Preferably, a heat dissipation rod is fixedly connected to the inner wall of the heat dissipation groove, and the heat dissipation rod is located inside the heat dissipation fin.

[0016] Preferably, a motherboard is fixedly connected to the inner bottom wall of the housing, and a humidity sensor is fixedly connected to the inner bottom wall of the housing.

[0017] The beneficial technical effects of this utility model are as follows: Pulling the fixing plate downward causes the insert plate to move the connecting rod downward, which in turn causes the connecting rod to slide with the connecting pipe, and the connecting pipe to slide with the limiting plate. This further compresses the spring to generate elastic force. Then, the insert plate is rotated to displace the insert plate from the slot. The sealing plate is then pulled out to expose the interior of the outer shell for inspection. After inspection, the sealing plate is reset, and the insert plate is rotated to align with the slot. The insert plate is then released, and under the action of the spring force, the connecting rod moves upward through the limiting plate, causing the insert plate to insert into the slot and fix the sealing plate. No screws need to be removed during the inspection process, resulting in fast inspection speed. Attached Figure Description

Detailed Implementation

[0025] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0026] like Figures 1-6 As shown, this embodiment provides a waterproof structure for an LED lamp, including a housing 1, a sealing plate 2, and a connecting mechanism disposed on the housing 1. The connecting mechanism includes a mounting plate 3, a connecting pipe 4 fixedly connected to the lower surface of the mounting plate 3, a connecting rod 5 slidably connected to the inner wall of the connecting pipe 4, a limiting plate 6 fixedly connected to one end of the connecting rod 5, the inner wall of the connecting pipe 4 slidably connected to the limiting plate 6, a spring 7 disposed inside the connecting pipe 4 and below the limiting plate 6, a fixing plate 8 rotatably connected to one end of the connecting rod 5, an insert plate 9 fixedly connected to the surface of the fixing plate 8, a slot 10 formed on the lower surface of the sealing plate 2, the inner wall of the slot 10 being inserted into the insert plate 9, and an anti-slip pad 11 fixedly connected to the upper surface of the insert plate 9, the anti-slip pad 11 enhancing the anti-slip capability of the insert plate 9. The shape of 11 is adapted to the slot 10. Pulling the fixing plate 8 downward causes the insert plate 9 to move the connecting rod 5 downward, which in turn causes the connecting rod 5 to slide with the connecting tube 4, and the connecting tube 4 to slide with the limiting plate 6. This further compresses the spring 7 to generate elastic force. Then, the insert plate 9 is rotated to make the insert plate 9 and the slot 10 misaligned. Then, the sealing plate 2 is pulled out to expose the inside of the outer shell 1 for inspection. After the inspection is completed, the sealing plate 2 is reset, and then the insert plate 9 is rotated to align the insert plate 9 with the slot 10. Then, the insert plate 9 is released. Under the action of the elastic force of the spring 7, the connecting rod 5 is moved upward through the limiting plate 6, so that the insert plate 9 is inserted into the slot 10 and the sealing plate 2 is fixed. No screws need to be removed during the inspection process, and the inspection speed is fast.

[0027] In this embodiment, as Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, a sealing gasket 12 is fixedly connected to the upper surface of the sealing plate 2, and an elastic gasket 13 is fixedly connected to the surface of the sealing gasket 12. A sealing groove 14 is provided on the upper surface of the outer shell 1. The inner wall of the sealing groove 14 is inserted into the elastic gasket 13. When installing the sealing plate 2, the elastic gasket 13 is inserted into the sealing groove 14, and then the sealing plate 2 is fixed by the connecting mechanism. Under the elastic force of the spring 7, the sealing gasket 12 and the elastic gasket 13 undergo elastic deformation, thereby improving the sealing performance at the connection between the sealing plate 2 and the outer shell 1.

[0028] In this embodiment, as Figure 1 As shown, the upper surface of the outer casing 1 is provided with equally spaced heat dissipation grooves 15. Heat dissipation fins 16 are fixedly connected to the inner wall of the heat dissipation grooves 15, and heat dissipation rods 17 are fixedly connected to the inner wall of the heat dissipation grooves 15. The heat dissipation rods 17 are located inside the heat dissipation fins 16. The outer casing 1 dissipates heat through the heat dissipation grooves 15. The heat dissipation fins 16 and heat dissipation rods 17 increase the contact area between the outer casing 1 and the air, thereby improving the heat dissipation effect of the outer casing 1.

[0029] In this embodiment, as Figure 1 and Figure 6 As shown, an LED light board 20 is embedded on the lower surface of the sealing plate 2. A protective film is pasted on the lower surface of the LED light board 20 to protect the LED light board 20 and prevent the surface of the LED light board 20 from being scratched. A main board 19 is fixedly connected to the inner bottom wall of the outer shell 1. A humidity sensor 18 is fixedly connected to the inner bottom wall of the outer shell 1 to detect the humidity inside the outer shell 1.

[0030] In this embodiment, as Figures 1-6 As shown in the figure, the working principle of the waterproof structure for LED lamps provided in this embodiment is as follows:

[0031] When installing the sealing plate 2, the elastic pad 13 is inserted into the sealing groove 14, and then the sealing plate 2 is fixed by the connecting mechanism. The insert plate 9 is pulled down, causing the connecting rod 5 and the connecting pipe 4 to slide, and the connecting pipe 4 and the limiting plate 6 to slide, further compressing the spring 7 to generate elastic force. Then the insert plate 9 is rotated so that the insert plate 9 is aligned with the slot 10. Then the insert plate 9 is released. Under the action of the elastic force of the spring 7, the connecting rod 5 is moved upward by the limiting plate 6, so that the insert plate 9 is inserted into the slot 10, and the sealing plate 2 is fixed.

[0032] When the sealing plate 2 is opened, the fixing plate 8 is pulled down, causing the insert plate 9 to move the connecting rod 5 downward, which in turn causes the connecting rod 5 to slide with the connecting pipe 4, and the connecting pipe 4 to slide with the limiting plate 6, further compressing the spring 7 to generate elastic force. Then, the insert plate 9 is rotated so that the insert plate 9 is misaligned with the slot 10. Then, the sealing plate 2 is pulled out to expose the inside of the outer shell 1, and the internal mechanism of the outer shell 1 is inspected.

[0033] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
