Embodiment Construction

[0015] A sealing structure for a high-clean lamp, comprising a housing 1, a lampshade 2 covered on the housing 1, and a sealing ring 4 that acts as a seal between the housing 1 and the lampshade 2, the sealing ring adopts a cross section of Trident structure. A protruding annular groove 6 is provided on the inner side of the housing 1 corresponding to the lampshade 2 , the sealing ring 4 is put into the annular groove 6 at one end, and the two side forks of the three-pronged part extend out of the annular groove 6 . The sealing ring 4 is a strip of sealing rubber made of anti-aging foamed silica gel.

[0016] A gap can also be set on the annular groove 6, and the sealing ring 4 can adopt the form of a sealing strip, and two ends of the sealing ring strip are drawn from the gap. When the sealing ring 4 is installed, one end of the sealing ring 4 can be passed through the gap, and then the sealing ring 4 is placed along the annular groove 6, and the end of the sealing ring 4 is...

Abstract

The invention discloses a sealing structure of a high-cleaning lamp, which comprises a shell, a lampshade and a sealing ring, wherein the lampshade covers the shell, and the sealing ring is arranged between the shell and the lampshade and used for sealing. The sealing structure is characterized in that the shell is provided with an annular groove; the sealing ring adopts section with a trident-shaped structure; a single head of the sealing ring is placed inside the annular groove of the sealing ring; two forks of the trident part extend out of the annular groove; and a bolt is utilized to lock the shell and the lampshade for sealing. The sealing structure has the advantages of good tightness, simple structure and long service life, and can be widely applied to various high-cleaning places, such as laboratories, sterilization rooms, high-cleaning workshops and the like.

Description

technical field [0001] The invention relates to a sealing structure, in particular to a sealing structure of a high-clean lamp. Background technique [0002] The existing sealing structure of clean lights, such as dust-proof clean lights suitable for high-clean occasions, waterproof lights suitable for underwater, etc., all adopt sealing ring structures, but traditional sealing rings are all single-layer structures, and if they are used for a long time , once it ages, it loses its sealing effect. In addition, a relatively complicated internal structure is adopted to ensure sealing. For example, Chinese application number 200680008228.9 discloses a lamp with a shading device, and others have at least one light-emitting mechanism arranged inside a lamp tube, wherein the lamp tube is fixed within a fixed part of a lamp socket, and the lamp has a shade. This structure has a good sealing effect, but the structure is relatively complicated and the cost is high. Contents of the...
