Abstract

The invention provides an elastic sealing element, which comprises a body made of elastic materials, wherein the body consists of a supporting part and a compression part which are integrally formed, the bottom of the supporting part is a plane, the compression part is a bulge extending out from the top of the supporting part, and at least one wing part is convexly and outwards arranged on the supporting part on at least one side surface of the body. The invention has simple structural design, the compression amount of the sealing element is fully ensured by the compression part arranged on the supporting part, so line seams can not be generated on combining surfaces between connecting elements, the plane at the bottom of the supporting part has the effect that the sealing element can stably sit at the bottom of a sealing groove when being assembled, further, the outwards projected wing part on the supporting part can ensure that the sealing element can be clamped in the sealing groove, the sealing effect of the sealing element is good, and in addition, the assembly is very convenient.

Description

technical field

[0001] The invention relates to the technical field of sealing, in particular to the design of an elastic sealing member structure. Background technique

[0002] Seals are components used to prevent fluid or solid particles from leaking from adjacent joint surfaces and external impurities such as dust, sand, moisture, etc. from intruding into the interior of the equipment.

[0003] Lamps used for lighting, especially those installed outdoors, have strict requirements on sealing due to the environment in which they are used, and appropriate measures must be taken to prevent dust, moisture or water from entering the lamps. However, an O-shaped sealing ring is used as a seal between the front cover and the housing of the existing lamp products. Its cross section is oval, and the compression is between 20% and 40%. Large, but when the compression amount of the O-shaped sealing ring is not enough, there will be a problem that the compression amount meets the requ...

Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] see Figure 5 , Image 6 , the present invention provides an embodiment structure of the application of the sealing member disposed between the lamp housing 2 and the front cover 3 .

[0021] see Figure 1-Figure 6 , the seal includes a body 1, which can be made of elastic rubber or soft rubber material, the body 1 is composed of a support portion 11 and a compression portion 12, the two are integrally formed to facilitate processing and reduce material costs; The width of the support part 11 is adapted to the width of the seal groove on the front cover 3, and its bottom 111 is a plane, w...
