Mounting device for preventing screw from being lost or staggered during machine repair or automobile repair

Abstract

A device for preventing a screw from being lost or staggered during machine repair or automobile repair relates to a device for preventing the screw from being lost during equipment disassembly, a U-shaped rod of a clamp spring is positioned on the outer surface of a connecting block (11) formed between two shallow grooves (13) of an insertion rod (12), two inner bulges (19) of the clamp spring are respectively clamped in two recesses (14), and two long rods (10) are respectively hidden in two side notches of a groove (3). The two outwards-bent hooks (1) are respectively exposed at the front part of the groove (3); the two outer bulges (2) are respectively positioned on the outer side wall of the unthreaded hole of the structural member, and the two outer bent hooks (1) are respectively hooked on the inner side wall of the unthreaded hole of the structural member after being inserted into the unthreaded hole of the structural member; the rear end of the insertion rod (12) is connected to the block body (5), and the block body (5) is further provided with an unloading bolt containing screw hole (7). The block body is provided with a screw rod capable of being connected with a screw hole or an insertion rod clamping spring of an unthreaded hole, in-situ fixing or recognition is achieved, and the screw is further prevented from being lost or installed in a staggered mode.

Description

【Technical field】 [0001] The invention relates to an anti-lost device for screws when equipment is removed, in particular to a device for preventing loss or dislocation of screws during machine repair or auto repair. 【Background technique】 [0002] In the process of machine repair, the connection between structural parts is mainly obtained by screws, nuts or individual screws. Most of the joints of the two structural parts are provided with two light holes corresponding to each other. The connection at this time is through Screws and nuts; or one of the two structural parts has a light hole and the other corresponding hole is a screw hole, and the two structural parts are connected by screws; because there are many equipment parts, the number of screws and nuts to be removed is very large. If there are many years of experience Technicians can install all the removed screws and nuts one by one through experience, but some novice or inexperienced technicians will leave some sc...

[0002] In the process of machine repair, the connection between structural parts is mainly obtained by screws, nuts or individual screws. Most of the joints of the two structural parts are provided with two light holes corresponding to each other. The connection at this time is through Screws and nuts; or one of the two structural parts has a light hole and the other corresponding hole is a screw hole, and the two structural parts are connected by screws; because there are many equipment parts, the number of screws and nuts to be removed is very large. If there are many years of experience Technicians can install all the removed screws and nuts one by one through experience, but some novice or inexperienced technicians will leave some screws and nuts after the equipment is installed, and they can’t figure out where the screws and nuts are not installed. , causing the installation to fail, and had to be installed again; there are also some equipment installations that are limited by cost, and some important parts use screws with special pitches, the same outer diameter and the same model, but different pitches or materials. The proper function cannot be fully exerted, and some low-quality screws are installed in these parts, resulting in a decrease in the quality of the equipment; in order to prevent the screws from being installed incorrectly, many technicians with extremely high memory have become high salaries in the machine repair industry and the object of competition for enterprises
