Push-pull tube structure of gun bolt tightener

Abstract

The invention discloses a push-pull pipe structure of a gun type bolt tightening device. A front end pipe opening of a push-pull pipe is an opening, and a notch A is formed in the upper side of the rear end of the side wall of the push-pull pipe. The lower portion of the side wall of the rear end of the push-pull pipe is upwards provided with an operation vertical plate. A push-pull rod is arranged in the push-pull pipe in a penetration manner. The outer wall of the push-pull rod is matched with the inner wall of the push-pull pipe. The rear end of the push-pull rod is located in the notch A,and the front end of the push-pull rod forwards stretches out of the front end pipe opening of the push-pull pipe. The front end of the push-pull rod is provided with a limiting baffle matched with the push-pull pipe in outer diameter. A protruding block A is upwards fixed to the upper portion of the rear end face of the push-pull rod, and a drag hook located on one side of the push-pull rod is arranged on the front end face of the push-pull rod. It can be known from the above structure that the push-pull pipe structure of the gun type bolt tightening device achieves rapid replacement of a bolt tightening device unit, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of a bolt tightener, in particular to a push-pull tube structure of a gun-type bolt tightener. Background technique [0002] Bolts (commonly known as screws): mechanical parts, cylindrical threaded fasteners with nuts. 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, so the bolt connection is a detachable connection. [0003] Bolts have various head shapes: cylindrical head, countersunk head, countersunk head, spherical cylindrical head, pan head, half round head, hexagonal head. Corresponding to different head shapes of bolts, different bolt tightening tools need to be used, including flat-blade screwdrivers (commonly known as screwdrivers), Phillips screwdrivers, ring wren...

AI Technical Summary

Problems solved by technology

[0004] However, in the process of actually disassembling a certain product or equipment, different bolts will be encountered, so it is necessary to equip the corresponding bolt tightening tools, which makes it inconvenient for the operator to carry, and the bolt tightening tools need to be replaced at any time during use, resulting in low work efficiency
