In the figure: 1. 1-1 part of a silica gel ring body, 1-11 parts of a conical surface, 1-111 parts of a sealing bulge, 1-2 parts of a concave surface, 1-3 parts of a clamping groove, 1-4 parts of an annular gap, 1-5 parts of a bottom edge, 2 parts of an elastic cavity, 2 parts of a lampshade, 2-1 parts of an annular clamping edge, 3 parts of a lamp shell, 3-1 parts of a mounting groove, 3-11 parts of a bayonet, 4 parts of a gland.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic drawings, which illustrate the basic structure of the invention only in a schematic way, and thus show only the components that are relevant to the invention, and the directions and references (e.g., upper, lower, left, right, etc.) may be used only to help describe the features in the drawings. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the claimed subject matter is defined only by the appended claims and equivalents thereof.

Example 1

As shown in fig. 1, the silica gel ring for the street lamp comprises a silica gel ring body 1, wherein the outer peripheral surface of the silica gel ring body 1 is a conical surface 1-1, the conical surface 1-1 inclines outwards from top to bottom, a clamping groove 1-2 for clamping an annular clamping edge 2-1 of a lampshade 2 in the street lamp is arranged in the silica gel ring body 1 along the axial direction, an annular gap 1-3 communicated with the clamping groove 1-2 is arranged at the bottom end of the inner peripheral surface of the silica gel ring body 1, and a bottom edge 1-4 is formed at the bottom end of the silica gel ring body 1.

The outer peripheral surface of the silica gel ring body 1 extends upwards along the axial direction thereof to form an annular sealing bulge 1-11; when the silica gel ring body 1 is pressed, the annular sealing bulges 1-11 can enable the silica gel ring body 1 to be better extruded towards the direction of the clamping groove 1-2, so that the sealing performance between the silica gel ring and the lampshade 2 is improved, the contact area between the silica gel ring and the lamp shell 3 is also increased, and the sealing performance between the silica gel ring and the lamp shell 3 is also improved.

The upper surface of the sealing bulge 1-11 is a concave surface 1-111 which is concave downwards; the provision of the depressed surfaces 1-111 improves the sealing area and thus improves the sealing performance.

An elastic cavity 1-5 is arranged in the silica gel ring body 1; the elastic cavity 1-5 can be easily deformed when the silica gel ring body 1 is pressed.

As shown in fig. 2 and 3, when the silicone rubber ring for street lamps of this embodiment is used, firstly, the annular clamping edge 2-1 at the edge of the lamp shade 2 is embedded into the clamping groove 1-2 of the silicone rubber ring body 1 from the annular notch 1-3 of the silicone rubber ring body 1, then the silicone rubber ring is placed into the mounting groove 3-1 of the lamp housing 3, the annular sealing protrusion 1-11 of the silicone rubber ring body 1 is abutted against the bayonet 3-11 at the inner wall of the mounting groove 3-1, then the gland 4 is fixed on the lamp housing 3 through the bolt assembly, the silicone rubber ring body 1 is compressed between the gland 4 and the lamp housing 3, the upper surface of the gland 4 is in contact with the bottom surface of the silicone rubber ring body 1 and the bottom surface of the bottom edge 1-4, and the bottom edge 1-4 is also firmly attached to the lower surface of the lamp shade 2 to form sealing; when the silica gel ring is pressed by the pressing cover 4, the conical surface 1-1 of the silica gel ring body 1 can enable the silica gel ring to be extruded inwards better, so that the clamping groove 1-2 of the silica gel ring body 1 firmly clamps the annular clamping edge 2-1 on the inner lampshade 2, the silica gel ring can be firmly attached to the mounting groove 3-1 of the lamp housing 3 and the annular clamping edge 2-1 of the lampshade 2, and a larger sealing area can be reserved between the silica gel ring and the lamp housing 3 and the lampshade 2, and the sealing performance is effectively improved, and the sealing performance is more stable and reliable.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
