A locking and sealing structure and a lamp with the locking and sealing structure

Abstract

The present invention provides a locking and sealing structure, which is used to lock the seal between the first part and the second part. Both the first part and the second part are in the shape of a truncated cone. The seal is arranged between the large ends of the second part, and the first part and the second part are fixed by a fixing device; the locking and sealing structure includes a sealing member arranged on the first part A locking assembly near the periphery of the small end and a notch provided at the large end of the second component, the locking assembly includes a rotatable union bolt and a threaded joint with the union bolt A union nut is connected, the notch cooperates with the union bolt to be screwed into or out of the notch, and the union nut is used to tighten or loosen the union bolt in the notch. The invention also provides a lamp with the locking and sealing structure. The locking and sealing structure of the present invention has the advantages of convenient maintenance, simple operation and reliable sealing.

Description

Technical field [0001] The invention relates to a lighting device, in particular to a locking and sealing structure and a lamp with the locking and sealing structure. Background technique [0002] Lamps such as floodlights used on cranes such as ports and docks, including main reflector assembly and secondary reflector assembly, are sealed by installing seals between them, and the seals are fixed and locked to ensure that the seals can be effective Seal the above-mentioned primary and secondary reflector components. The locking and sealing structure used to fix and lock the seals in the existing lamps is relatively complicated, and the assembly and subsequent maintenance are not convenient. When the light source is replaced, it is not easy to disassemble the main reflector assembly and the auxiliary reflector assembly. It is convenient for maintenance and long-term use of lamps. It can be seen that the locking and sealing structure of the lamp in the prior art is relatively com...
