Abstract

The invention discloses a bolt, which includes a bolt head and a screw rod. The bolt head includes a fixing part integrated with the screw rod, and a rotating part separate from the screw rod. The fixing part and the rotating part are semi-cylindrical, and the cross sections of the fixing part and the rotating part are fitted together; The fixed part and the rotating part are provided with communication holes, and a pin shaft passes through the communication hole to hinge the rotating part and the fixed part, so that the rotating part can rotate around the pin shaft; the distance between the connecting hole and the end of the rotating part near the screw is greater than that of the rotating part The distance between the connecting hole and the other end of the rotating part is greater than the diameter of the screw; the bolt provided by the present invention has a rotating part that can rotate under the action of gravity, by adjusting the rotating part to be inserted into the screw hole parallel to the screw rod, and then Then rotate the rotating part by 90° to clamp the inner wall of the plate to be fastened, and then cooperate with the nut to realize the fastening and quick disassembly functions of the plate in a narrow and closed space.

Description

technical field [0001] The present application relates to the technical field of mechanical manufacturing engineering, in particular to a bolt and a bolt assembly. Background technique [0002] A bolt is a cylindrical threaded fastener with a nut. The bolt consists of two parts, the head and the screw rod, which need to be used in conjunction with the nut to fasten and connect two parts with through holes. Usually when using bolts, it is necessary to tighten the bolt head at one end of the screw rod and the matching nut at the other end on both sides of the fastened object at the same time to achieve a good fastening effect; but in some special application scenarios, such as belts The internal operating space of the fastening object is very narrow, or when the internal space is closed, manpower or tools cannot enter the internal space, and the nuts or bolt heads cannot be tightened on both sides at the same time, and only one can be tightened, resulting in bolted connection...
