Abstract
The invention discloses a bolt protecting cover comprising a cover body. The cover body is a circular sleeve of which [the] upper part is sealed; the top part of the cover body is provided with an irregular opening groove, one end of a lower opening of the cover body is provided with a fixed connecting base; the fixed connecting base is provided with an outside thread, the inner edge of the opening of the cover body is provided with a corresponding inner thread and in threaded connection with the fixed connecting base; a hole is formed in the center of the fixed connecting base, a screw of the bolt can pass through the hole and fix the fixed connecting base through the nut. The protecting cover can relatively isolate the screw and the nut from the working environment and avoid the pollution of the working environment on the screw and the nut for fastening the bolt, so that the protecting cover plays a good protecting role; and the top part of the cover body is provided with an irregular opening groove to prevent thefts.
Description
Technical field:
The present invention relates to a kind of clamping bolt protective housing.
Background technique:
