Embodiment Construction

[0020] 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.

[0021] see Figure 1-Figure 6 , the present invention provides a fixed radial seal, which is arranged between the upper shell 1 and the lower shell 2 that are matched and connected to each other, see Figure 5 , the upper casing 1 and the lower casing 2 are fixedly connected by threaded connection, and the end surface of the lower casing 2 in contact with the upper casing 1 is provided with a groove (not marked in the figure), so that the lower casing 2 The upper end forms a lower end surface 21 and an inner surface 22; at the same time, an upper end surface 11 and an outer surface 12 are provided...

Abstract

The invention discloses a fixed radial sealing piece. The fixed radial sealing piece is arranged between an upper shell and a lower shell which are correspondingly matched and connected with each other, comprises a body made of a flexible material, and is characterized in that: at least one first groove capable of tolerating the body to be deformed by force in the axial direction is formed on the body; and the section of the first groove can be a concave arc, a triangle, a trapezoid, a wooden club, a square or a rectangle. By using the structural design of the sealing piece of the invention, relatively large axial deformation can be tolerated, so that relatively large clearance fit between the upper shell and the lower shell is not needed, assembly is convenient, meanwhile, the machining precision of the fitting surfaces of the upper and lower shells can be reduced, and the machining cost can be saved; and the abrasive damage of the sealing piece in the rotational locking process of the upper and lower shells is relatively small, so that sealing reliability is further improved.

Description

technical field [0001] The invention relates to the technical field of sealing, in particular to a design of a radial seal structure at the thread joint between parts of a lamp housing. Background technique [0002] Existing lampholders generally have a lampholder housing consisting of fixed housing parts and a threaded sleeve joint which in turn consists of a threaded ring, a spacer ring for the lampholder closure and a seal for the tube or lamp , two housing parts enclose an inner cavity, which is provided with a connecting device for the contact of the fluorescent lamp, and in addition, a sealing ring is arranged in the inner cavity to prevent foreign impurities from entering. With the continuous development and progress of lighting technology, lighting fixtures, especially lamps with higher protection levels, have strict requirements on sealing. Appropriate measures must be taken to prevent dust, moisture or water from entering the lamp holder, especially The electrical...
