Description

Technical Field

[0001] The utility model relates to the field of heat-conducting gaskets, and specifically to a heat-conducting gasket that is convenient for installation and positioning. Background Technique

[0002] In the manufacture of lamps, the application of heat-conducting gaskets is crucial. It is responsible for conducting and dissipating the high temperature generated by the lamps during operation to ensure the stable operation of the lamps and extend their service life. Most traditional heat-conducting gasket installation methods rely on screws or adhesives for fixation, but these methods have many inconveniences in actual applications. For example, the screw fixation method is not only cumbersome to operate, but also prone to the displacement of the heat-conducting gasket due to screw loosening, affecting the heat dissipation effect; while the adhesive fixation method may fail due to the aging or peeling of the adhesive.

[0003] In view of the above problems, there is an urgent need in the current market for a heat-conducting gasket that is convenient for installation and positioning and has a good fixation effect. This kind of heat-conducting gasket needs to be able to easily connect with the lamp aluminum substrate and the clamping piece, and does not require too many tool aids during the installation process. At the same time, it also needs to have good heat dissipation performance to ensure the stable operation of the lamp. Content of the Utility Model

[0004] The purpose of the utility model is to provide a heat-conducting gasket that is convenient for installation and positioning to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A heat-conducting gasket that is convenient for installation and positioning, including a heat-conducting silica gel gasket, which is clamped between the lamp aluminum substrate and the clamping piece. A silica gel cover is integrally formed on the outer ring surface of the heat-conducting silica gel gasket, and the silica gel cover is sleeved on the heat-conducting silica gel gasket. A side groove is opened on the outer ring surface of the heat-conducting silica gel gasket.

[0006] Preferably, a first reserved hole is opened on the surface of the lamp aluminum substrate, a second reserved hole is opened on the surface of the heat-conducting silica gel gasket, and a third reserved hole is opened on the surface of the clamping piece. The first reserved hole, the second reserved hole, and the third reserved hole are penetrated by a bolt. After the bolt is tightened, the heat-conducting silica gel gasket is clamped between the lamp aluminum substrate and the clamping piece.

[0007] Preferably, both the heat-conducting silica gel gasket and the clamping piece are circular plates. The outer diameter of the clamping piece is smaller than the outer diameter of the heat-conducting silica gel gasket, and the inner diameter of the clamping piece is equal to the inner diameter of the heat-conducting silica gel gasket.

[0008] Preferably, a silica gel plug ring is integrally formed on the inner wall of the second reserved hole. The outer diameter of the silica gel plug ring is equal to the aperture of the first reserved hole. After the heat-conducting silica gel gasket is attached to the lamp aluminum substrate, the silica gel plug ring is inserted into the first reserved hole. When the bolt penetrates the first reserved hole and the second reserved hole, the silica gel plug ring is clamped between the bolt and the first reserved hole and the second reserved hole and generates elastic deformation.

[0009] Preferably, the silica gel cover is in a ring-shaped plate structure, and the inner ring diameter of the silica gel cover is equal to the diameter of the lamp aluminum substrate body.

[0010] Preferably, the side groove is a ring-shaped groove, and the inner ring diameter of the side groove is larger than the outer ring diameter of the clamping piece.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0022] In order to clearly and completely describe the purpose and technical solution of the present utility model and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present utility model.

[0023] Please refer to Figures 1-8 , the present utility model provides a technical solution: a heat-conducting gasket that is convenient for installation and positioning, including a heat-conducting silicone gasket 1, the heat-conducting silicone gasket 1 is clamped between the lamp aluminum substrate 2 and the clamping piece 3. Both the heat-conducting silicone gasket 1 and the clamping piece 3 are circular plates. The outer diameter of the clamping piece 3 is smaller than the outer diameter of the heat-conducting silicone gasket 1, and the inner diameter of the clamping piece 3 is equal to the inner diameter of the heat-conducting silicone gasket 1. A first reserved hole 4 is provided on the surface of the lamp aluminum substrate 2, a second reserved hole 5 is provided on the surface of the heat-conducting silicone gasket 1, and a third reserved hole 6 is provided on the surface of the clamping piece 3. The first reserved hole 4, the second reserved hole 5, and the third reserved hole 6 are penetrated by a bolt 8. After the bolt 8 is tightened, the heat-conducting silicone gasket 1 is clamped between the lamp aluminum substrate 2 and the clamping piece 3; the heat-conducting silicone gasket 1 is installed between the lamp aluminum substrate 2 and the clamping piece 3 through the bolt 8. After the heat-conducting silicone gasket 1 adsorbs the high temperature generated during the operation of the lamp aluminum substrate 2, it dissipates externally. After the heat-conducting silicone gasket 1, the lamp aluminum substrate 2, and the clamping piece 3 are connected, they are inserted into the lamp heat dissipation housing for fixation.

[0024] A silicone plug ring 7 is integrally formed on the inner wall of the second reserved hole 5. The outer diameter of the silicone plug ring 7 is equal to the aperture of the first reserved hole 4. After the heat-conducting silicone gasket 1 adheres to the lamp aluminum substrate 2, the silicone plug ring 7 is inserted into the first reserved hole 4. When the bolt 8 penetrates the first reserved hole 4 and the second reserved hole 5, the silicone plug ring 7 is clamped between the bolt 8 and the first reserved hole 4 and the second reserved hole 5 and undergoes elastic deformation; the reason for adding the silicone plug ring 7 is that when the heat-conducting silicone gasket 1 adheres to the lamp aluminum substrate 2, the silicone plug ring 7 is inserted into the first reserved hole 4 to realize the installation and positioning of the heat-conducting silicone gasket 1 on one side of the lamp aluminum substrate 2. And when the bolt 8 penetrates the first reserved hole 4, the second reserved hole 5, and the third reserved hole 6 to fix the heat-conducting silicone gasket 1, the lamp aluminum substrate 2, and the clamping piece 3, the silicone plug ring 7 is clamped between the bolt 8 and the first reserved hole 4 and the second reserved hole 5 to prevent the bolt 8 from loosening.

[0025] The outer ring surface of the heat-conducting silicone gasket 1 is integrally formed with a silicone cover 9. The silicone cover 9 is sleeved on the heat-conducting silicone gasket 1. The silicone cover 9 is in a ring-shaped plate structure. The inner ring diameter of the silicone cover 9 is equal to the plate diameter of the lamp aluminum substrate 2. An edge groove 10 is formed on the outer ring surface of the heat-conducting silicone gasket 1. The edge groove 10 is a ring-shaped groove. The inner ring diameter of the edge groove 10 is larger than the outer ring diameter of the clamping piece 3. The silicone cover 9 is sleeved on the outside of the heat-conducting silicone gasket 1, but the silicone cover 9 does not completely wrap the side wall of the heat-conducting silicone gasket 1. After the silicone cover 9 adsorbs the heat of the heat-conducting silicone gasket 1, the heat is dissipated outward. The reason for forming the edge groove 10 is to increase the heat dissipation area of the heat-conducting silicone gasket 1.
