Problems solved by technology

Although this chute bolt can solve the fastening problem of the workpiece in the interlayer space, it is inconvenient to install and disassemble the bolt. When the bolt rod is pulled back and forth, the baffle plate is easy to break away from the bolt rod and cannot be reused; and for some For a workpiece with a relatively narrow interlayer space, the baffle cannot pass through the workpiece completely during fastening, so it cannot be used; in addition, a hole larger than the diameter of the bolt rod needs to be drilled on the workpiece in advance, which is very inconvenient to operate. convenient

Abstract

The invention discloses a bolt which comprises a screw rod, a nut, a push rod and a stop block; a guide hole coaxial with the screw rod is formed in the center of the screw rod; the push rod is arranged in the guide hole in a threaded connection manner, and the top end of the push rod, which is inserted in the guide hole, is tapered; a through groove is formed in the circumference of the screw rod in the direction perpendicular to the center line of the guide hole; and the stop block is positioned in the through groove and can side in the through groove. The bolt adopting the scheme and provided by the invention is applicable to fastening of various workpieces in sandwich space, and is very simple in operation; and only a hole with the diameter same as that of the screw rod is required to be drilled, so that the application range of the bolt is expanded, and the fastening strength of the workpieces is improved.

Description

technical field [0001] The invention relates to a fastener, in particular to a bolt, and belongs to the technical field of fastening parts. Background technique [0002] Bolts are composed of screws and nuts. When fixing a workpiece, the screw is passed through the workpiece and then tightened by the nut. However, for some workpieces that cannot be turned over or in the interlayer space, they can only be connected and fastened on the front of the workpiece, and the existing bolts cannot be used. For this reason, the Chinese patent No. is ZL 200920174809.0, a utility model patent named "chute bolt", which discloses a chute bolt. A chute is arranged on the bolt shank, and a baffle is placed in the chute. A hole larger than the diameter of the bolt shaft is drilled on the workpiece. After passing the screw rod and the baffle plate through the hole together, the screw rod is pulled to make the baffle plate stand up, and the workpiece is fixed. Although this chute bolt can solv...
