Description
Technical Field
The utility model relates to an explosion-proof lamp technical field especially relates to an explosion-proof lamp shade's solid fixed ring.
Background
Explosion-proof lamp shade is dust or gaseous contact in the electric arc in the lamp body and the exterior space when mainly used to avoid the illumination, produces the condition of explosion, and in order to solve this problem, explosion-proof lamp shade's seal and locking structure are important, and in order to ensure that the lamp shade leakproofness is strong and make things convenient for workman's equipment, it is very necessary to design a solid fixed ring.
Disclosure of Invention
The utility model aims to solve the technical problem that a solid fixed ring of explosion-proof lamp shade is provided, have simple structure, simple to operate, sealed effectual, characteristics such as easy location.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a solid fixed ring of explosion-proof lamp shade, including solid fixed ring body, the annular conical surface and spliced pole breach, solid fixed ring body up end edge evenly arranged round spliced pole breach, arranged the spliced pole structure that has the screw hole in the spliced pole breach, solid fixed ring body up end inner circle department arranged the annular conical surface of round inner circle slope down.
The lower end face of the fixing ring body is provided with a circle of positioning ring grooves.
The inner ring of the positioning ring groove and the inner ring of the lower end face of the fixing ring body are provided with a circle of positioning conical surface, and a plurality of positioning bulges are uniformly arranged on the positioning conical surface.
The positioning bulges are of parallelogram cylinder structures, and equidistant spaces are reserved between the adjacent positioning bulges.
Has the advantages that: the utility model relates to a solid fixed ring of explosion-proof lamp shade, concrete beneficial effect as follows:
(1) by arranging the annular conical surface, when the fixing ring is conveniently butted with the lamp cover, the cover body is attached to the fixing ring, and the cover body is positioned;
(2) the sealing ring is conveniently arranged by arranging the positioning ring groove, so that the lamp body is sealed after being butted with the fixing ring, and the electric arc leakage is avoided;
(3) the lamp body and the fixing ring are positioned and assembled by arranging the positioning protrusions, and the deviation is avoided when the fixing ring is locked.
Drawings
Fig. 1 is a front view of the present invention;
fig. 2 is a structural view of the upper end surface of the fixing ring body according to the present invention;
fig. 3 is a structural view of the lower end surface of the fixing ring body of the present invention.
The figure is as follows: 1. the fixing ring comprises a fixing ring body, 2, an annular conical surface, 3, a connecting column notch, 4, a connecting column structure, 5, a positioning ring groove, 6, a positioning conical surface, 7 and a positioning bulge.
Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
The utility model discloses an embodiment relates to a solid fixed ring of explosion-proof lamp shade, as shown in fig. 1-3, including solid fixed ring body 1, the annular conical surface 2 and spliced pole breach 3, solid fixed ring body 1 up end edge evenly arranged round spliced pole breach 3, arranged spliced pole structure 4 that has the screw hole in the spliced pole breach 3, solid fixed ring body 1 up end inner circle department arranged the annular conical surface 2 of round inner circle slope down.
The lower end face of the fixing ring body 1 is provided with a circle of positioning ring grooves 5.
A circle of positioning conical surface 6 is arranged between the inner ring of the positioning ring groove 5 and the inner ring of the lower end face of the fixing ring body 1, and a plurality of positioning bulges 7 are uniformly arranged on the positioning conical surface 6.
The positioning bulges 7 are of parallelogram cylinder structures, and equidistant spaces are reserved between the adjacent positioning bulges 7.
When solid fixed ring and lamp shade and lamp body equipment are fixed, at first install the sealing washer in solid fixed ring body 1 lower extreme terminal surface's positioning ring groove 5, later with solid fixed ring body 1 lock joint on the lamp body, fix a position through location arch 7, and realize solid fixed ring body 1 and the butt joint of lamp body through spliced pole structure 4 and screw, later carry out the equipment of explosion-proof lamp structure, after the completion, paste the lid at the toroidal cone 2, make the lid seal the explosion-proof lamp, this solid fixed ring can play convenient equipment, strengthen the effect of sealed effect.
