Abstract

The invention discloses a bolt which comprises a bolt head and a screw rod. The bolt head comprises a fixed part integrated with the screw rod and a rotating part separated from the screw rod, the fixed part and the rotating part are semi-cylindrical, and the cross sections of the fixed part and the rotating part are attached; the fixed part and the rotating part are provided with communication holes, and a pin shaft penetrates through the communication holes to hinge the rotating part and the fixed part so as to enable the rotating part to rotate around the pin shaft; and the distance betweenthe communication holes and the end, close to the screw rod, of the rotating part is greater than half the length of the rotating part, and the distance between the communication holes and the otherend of the rotating part is greater than the diameter of the screw rod. The bolt is provided with the rotating part capable of rotating under the action of gravity, the rotating part is adjusted to beparallel to the screw rod to be inserted into a screw hole, then the rotating part is rotated by 90 degrees to clamp the inner side plate wall of a plate to be fastened, and the bolt is matched witha nut, so that plate fastening and quick disassembling functions in a narrow and closed space can be realized.

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...
