Problems solved by technology

Sealing rings are divided into solid sealing rings and hollow sealing rings. Solid sealing rings are difficult to fit into the sealing groove due to difficulty in deformation. Compared with the solid sealing ring, there is a hollow hole in the center of the cross section. The hollow hole makes the sealing ring have a certain deformation space, so it is easier to fit into the sealing groove, but the hollow sealing ring is less subject to the shell pressure. Under the negative pressure inside the lamp and the washing of external water, it is easy to be distorted and deformed, which will affect the sealing effect

Embodiment Construction

[0020] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0021] refer to figure 1 , The lamp sealing ring 2 of the present invention is made of soft material, which includes: a ring-shaped body 21 and a plurality of barbs 22 arranged on the ring-shaped body. A square through hole 23 is dug out in the center of the ring-shaped body 21, so that the ring-shaped body 21 is a hollow square. For the convenience of sealing ring 2 assembly, the four corners of the square ring-shaped body 21 are also provided with circular arcs. Chamfer. Obviously, in other embodiments, the ring-shaped body 21 is not limited to a hollow square, and its shape can be changed according to actual needs, such as: circular ring, elliptical ring or other irregular shapes.

[0022] refer to figure 2 , the center of the section of the ring-shaped bo...

Abstract

Provided are a sealing ring of a lamp and the lamp. The sealing ring comprises a ring-shaped body provided with a through hole at the center and a plurality of inverted hooks arranged on the ring-shaped body. A hollow hole is arranged at the center of a cross section of the ring-shaped body and penetrates the whole ring-shaped body to form a closed cavity, and the cavity is full of gas. The outer surface of the ring-shaped body is formed by enclosing two end faces and two side faces, two end faces are parallel, two side faces are connected between the two end faces, the plurality of inverted hooks are distributed in pairs, one of each pair of inverted hooks is arranged on the periphery of the inner side face of the ring-shaped body for one circle in a protruding and surrounding mode, and the other of each pair of inverted hooks is arranged on the periphery of the outer side face of the ring-shaped body for one circle in a protruding and surrounding mode. The width of the ring-shaped body is gradually reduced from one end face to the other end face, and the size of the inverted hooks on the same side face gradually increases along the arrangement direction from the wide end face to the narrow end face. The sealing ring of the lamp is simple in assembly and good in sealing effect, and the service life of the lamp is prolonged.

Description

technical field [0001] The invention relates to a sealing structure, in particular to a sealing ring applied on the end face of a lamp. Background technique [0002] The luminaire includes a luminaire shell and a light bulb, an optical component and a circuit component in the shell. In order to facilitate replacement of the light bulb and maintenance, the luminaire shell is usually composed of two parts, namely the front shell and the rear shell. The two parts are connected by a hinged structure and passed through Snap closure. Generally, the sealing performance of the sealing ring is directly related to the service life of the lamp. In order to improve the sealing performance of the lamp and achieve the effect of waterproof and anti-corrosion, it is necessary to seal the end faces of the front shell and the rear shell. A common practice is to use a sealing ring to seal the contacting end faces of the front shell and the rear shell. Sealing rings are divided into solid sea...
