Protective cover

Abstract

The invention relates to a protective cover. The protective cover comprises a protective cover body and a protective cover connecting piece. The protective cover body comprises two protective cover sub-bodies. Each protective cover sub-body comprises two mating parts and a first rectangular groove. The two protective cover sub-bodies are fixed together through the mating parts so as to be bucked together, and thus an annular protrusion is formed. The protective cover connecting piece comprises two protective cover connecting sub-pieces. Each protective cover connecting sub-piece is provided with a second rectangular groove. The two protective cover connecting sub-pieces are inserted into the protective cover body, and fasteners are inserted into the first rectangular grooves and the second rectangular grooves so that the length of the protective cover can be adjusted in the length direction. The length dimension of the protective cover is adjusted in the length direction through the connecting piece, the protective cover is fixed through the fasteners, and the height dimension of the protective cover is adjusted in the height direction through a sliding block type support so that the number of protective covers of a series of products can be greatly reduced, the complexity of the products is reduced, the production efficiency is improved, and the product cost is reduced accordingly.

Description

technical field [0001] The invention relates to a protective cover, in particular to a protective cover which is installed on mechanical equipment and can be adjusted in the length direction and the height direction. Background technique [0002] The guard is a protective device installed on the mechanical equipment to protect the personal safety of the operator. At present, various shields are widely used in various fields of industry. However, the shape and geometric dimensions of the current shields are basically fixed. For some cases (such as non-serialized products), a fixed shape and geometry of the shield is reasonable. However, for serialized products, such as centrifugal pumps driven by prime movers (the pump shaft of the water pump and the drive shaft of the prime mover are connected together so that the power output by the prime mover is transmitted to the pump shaft of the water pump), different The water pump pump head (the central height of the pump shaft an...

AI Technical Summary

Problems solved by technology

For serialized products similar to centrifugal water pumps, many kinds of guards are required to meet the requirements of different lengths and / or heights, which increases the variety of materials and increases the complexity of production management and product management.

In order to reduce investment (such as mold cost, cost of accessories required for processing, etc.) Manufacture the shield according to the longest size, and cut it into shields of different lengths according to the needs in actual production; but this will cause waste of materials and increase assembly time, reducing production efficiency

The current technical solution for metal material shields is to divide the shield into two parts; design short-circuit parts of different lengths to adjust the size in the length direction; however, due to the large number of short-connects, it also causes a decrease in production costs and product management costs Increase
