Abstract

A tool for quick disassembly and assembly of nuts, including a sleeve connecting rod and a sleeve head, both of which are hollow structures, one end of the sleeve connecting rod is a square notch, and the other end is a square opening , the port at one end of the sleeve head is a square mouth, which is adapted to the square notch at one end of the sleeve connecting rod, and the other end of the sleeve head is a six-tooth bayonet, which is used to fix the six facets of the nut. The six-tooth bayonet of the barrel head has multiple standard sizes, which can be matched with common nuts to complete the disassembly and assembly of various types of nuts. The utility model effectively solves the problems of damaged nuts, scratches on hands, etc., which occur when the length bolts in the traditional narrow depth space and the locking nuts of the vibration probe are disassembled and assembled. At the same time, it solves the problem that the traditional socket wrench with a long vibration signal transmission cable inside cannot disassemble and assemble the nut due to the existence of the signal transmission cable. The whole device is also disassembled into small parts, which are relatively easy to use and store, and the device is simple to manufacture, low in cost and strong in practicability.

Description

A tool for quick disassembly and assembly of nuts

technical field

The utility model relates to a tool, in particular to a nut of a length bolt and a device for disassembling and assembling the nut of a vibrating probe.

Background technique

When overhauling large-scale equipment such as fans, it is necessary to complete the disassembly and assembly of the following two types of nuts: one is the bolts and matching nuts in a narrow depth space. After the bolts are inserted, the nuts cannot be touched, and the nuts cannot be disassembled. The other is the fixed lock nut of the vibration probe. Since the long vibration signal transmission cable is worn inside the fixed lock nut, the traditional socket wrench cannot disassemble the nut due to the existence of the vibration signal transmission cable. For the disassembly and assembly of the above two kinds of nuts, the traditional method is to extend the needle-nose pliers into the narrow space where the nut is located, clamp the jaws on the two facets of the nut, and pull the needle-nose pliers to disassemble. This method of disassembly and assembly is very easy to damage the nut, and it is difficult to disassemble and assemble, the fastening is not reliable, and the arm is very easy to be damaged, so there is a large potential safety hazard.

Utility model content

The technical problem to be solved by this utility model is to provide a tool for quick disassembly and assembly of nuts in view of the shortcomings in the prior art. The fixed lock nut, so as to achieve the purpose of fast and safe disassembly and assembly of the nut.

Adopt following technical scheme for solving the technical problem of the present utility model:

A tool for quick disassembly and assembly of nuts, including a sleeve connecting rod and a sleeve head, both of which are hollow structures, one end port of the sleeve connecting rod is a square notch, and the other end The port is a square port, and the port at one end of the sleeve head is a square port, which is adapted to the square notch at one end of the sleeve connecting rod, and the other end of the sleeve head is a six-tooth bayonet for fixing the nut Six facets, the six-tooth bayonet of the sleeve head has multiple standard sizes, which can be matched with common nuts to complete the disassembly and assembly of various types of nuts.

One end of the square opening of the sleeve connecting rod is provided with a handle through hole.

There are several sleeve connecting rods, which are socketed with each other through square openings and square notches at both ends of the sleeve connecting rods.

The utility model innovatively designs a tool for quick disassembly and assembly of nuts, which effectively avoids and solves the damaged nuts and scratches that occur when the length bolts in the traditional narrow depth space and the fixed locking nuts of the vibration probe are disassembled. hand and other issues. At the same time, it solves the problem that the traditional socket wrench cannot disassemble the nut due to the existence of the vibration signal transmission cable because of the long vibration signal transmission cable inside. The whole device is also disassembled into small parts, which are relatively easy to use and store, and the device is simple to manufacture, low in cost and strong in practicability.

detailed description

Below in conjunction with accompanying drawing, the utility model is described in detail:

As shown in Figure 1 and Figure 2, a tool for quick disassembly and assembly of nuts includes a sleeve connecting rod 1 and a sleeve head 2, both of which are hollow structures, and the sleeve connecting rod 1. The port at one end is a square notch, and the port at the other end is a square notch. There are several sleeve connecting rods 1, which are socketed with each other through the square notch and the square notch at both ends of the sleeve connecting rod 1. One end of the square opening of the sleeve connecting rod 1 is provided with a handle perforation 7 . The port at one end of the sleeve head 2 is a square opening, which is adapted to the square notch at one end of the sleeve connecting rod 1, and the other end of the sleeve head 2 is a six-tooth bayonet, which is used to fix the six facets 6 of the nut. The six-toothed bayonet sockets of the socket head 2 have multiple standard sizes, which can be matched with commonly used nuts to complete the disassembly and assembly of various types of nuts.

The utility model is composed of a sleeve connecting rod 1 and a sleeve head 2. In actual use, first pass the signal transmission cable through the hollow structure of the sleeve head 2 and the sleeve connecting rod 1 in turn (if there is no signal transmission cable when it is removed or installed nut, this step is omitted), then connect the square opening 4 of the sleeve connecting rod 1 with the square notch 3 of the sleeve head 2, and then connect the six toothed bayonets 5 of the sleeve head 2 with the nut The six facets 6 are fully engaged. Due to the narrow space for disassembly and assembly, several sleeve connecting rods 1 can be selected for socketing according to the actual situation on site, and a screwdriver or steel pliers of appropriate length can be inserted into the handle perforation 7, and the handle perforation 7 can be rotated. Use the inserted screwdriver or steel pliers to disassemble the nut.

By using a simple tool for disassembling and assembling nuts, the disassembly and assembly of length bolts and vibration probe locking nuts in narrow depth spaces can be safely and quickly completed, reducing labor intensity and effectively improving production efficiency.
