AI Technical Summary

Technical Problem

The installation structure of the existing explosion-proof switch is complex, making it difficult to achieve overall pull-out inspection and replacement of the movement. The positioning accuracy of the double-guiding support structure is low, resulting in increased manufacturing difficulty, complex assembly, high cost and unstable quality.

Method used

The single-sliding track movement installation structure is adopted, and by setting sliding components and stops in the explosion-proof housing, the stable installation and convenient maintenance of the electrical movement and the explosion-proof housing are achieved.

Benefits of technology

The installation structure is simplified, the positioning accuracy requirements are reduced, the convenience of assembly and inspection is improved, the cost is reduced, and the quality and quality stability of the product are enhanced.

Abstract

The utility model belongs to the technical field of mining explosion-proof electric appliances, and particularly relates to a single slide rail machine core mounting structure for an explosion-proof switch, which comprises an explosion-proof shell, an explosion-proof front door group is arranged on the right side of the explosion-proof shell, and a supporting plate is arranged in the explosion-proof shell. A sliding assembly capable of enabling the supporting plate to move is arranged between the explosion-proof shell and the supporting plate, the right / left side of the sliding assembly is provided with a front check block, the left / right side of the sliding assembly is provided with a rear check block, the top of the supporting plate is fixedly provided with an electric appliance mounting plate, and the right side of the electric appliance mounting plate is fixedly provided with an electric appliance machine core; the utility model effectively solves the problems that the existing mounting structure is complicated in structure, high in required positioning accuracy and complicated in assembly and inspection; and the problems that the cost is increased, the matching between the machine core and the guide rails is loose, the pull-out and push-in resistances are large and non-uniform, and the product quality is difficult to improve due to the processing of non-standard double guide rails with large transverse frame quantity are solved.
