Detachable bolt

Abstract

The invention provides a detachable bolt. The detachable bolt comprises an end cap, a rod core, a screw barrel and a limiting piece. The end cap is provided with a limiting groove, and the end cap isprovided with a receiving groove at the bottom of the limiting groove. The rod core is fixedly connected with the end cap. The screw barrel comprises an upper rod part, a middle rod part and a lower rod part. The screw barrel is provided with a screw joint through groove, and the rod core is inserted into the screw joint through groove and is in threaded connection with the upper rod part, the middle rod part and the lower rod part. The upper rod part is inserted into the receiving groove and is connected with the end cap. The limiting piece is provided with a connecting port, the middle rod part is inserted into the connecting port, and the limiting piece is in sliding connection with the middle rod part. The connecting port is a prismatic opening, and the middle rod part is of a prismatic structure. The receiving groove is a prismatic groove, and the limiting piece is of a prismatic sheet structure. The limiting piece is inserted into the receiving groove. A clamping groove is formedin the receiving groove of the end cap, the limiting piece is provided with a clamping block, and the clamping block is inserted into the clamping groove and connected with the end cap in a clampingmanner. The detachable bolt achieves the detachable assembly performance, is broadened in adaptation range and achieves effective pertinence.

Description

technical field [0001] The invention relates to the technical field of bolts, in particular to a detachable bolt. Background technique [0002] A bolt is a mechanical part, usually a cylindrical threaded fastener used with a nut. That is, a type of fastener consisting of a head and a screw (a cylinder with external threads), which needs to be matched with a nut to fasten two parts with through holes. This connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated. [0003] However, the current bolts are all integrally formed, and the head (end cap) of the bolt and the screw rod cannot be separated, so that the head (end cap) or the screw rod of the bolt cannot be replaced separately. It makes it impossible for different finished products to be converted by replacing parts, which reduces the reusability of products, and leads to a large stock of finished products in the warehouse, which is not conducive to reducing inve...
