Description

Socket head device of socket wrench

Technical Field

The utility model belongs to the technical field of the spanner, concretely relates to box end device of box end wrench.

Background

The nut dismounting tools commonly used in the aircraft manufacturing industry at present are mainly open-end wrenches and socket wrenches. The open end wrench is generally used for dismounting the relay in the airplane tray box, but the open end wrench cannot be used due to the fact that finished parts are more in the tray box and the space is narrow; although box spanner is applicable to the bolt or the nut of dismantling the very narrow and small or sunken very depths in position, nevertheless because of the overhead nut buckle of its hexagonal cover section of thick bamboo be whole circle structure, when the installation nut of needs dismouting relay, if the nut does not have the construction space by one side of relay shell, then causes current sleeve can't use.

Disclosure of Invention

The invention aims to: the sleeve head device of the socket wrench is used for dismounting and fixing a nut when no construction space exists on one side.

The technical scheme is as follows:

a socket head assembly for a socket wrench, comprising: the sleeve head 1 is provided with a sleeve head,

the sleeve head 1 is provided with a barrel, one end of the sleeve head 1 is of a side opening type inner wrench structure, the side face of the sleeve head is of an opening structure, the inner wrench structure used for meshing rotation is arranged inside the sleeve head, and the other end of the sleeve head 1 is provided with a notch 3.

The inner wrench structure is an inner hexagonal hole, an inner square hole, an inner quincuncial hole or an inner threaded hole structure.

The side opening of the side opening type inner wrench structure is positioned at the radial 1/3-1// 2 diameter.

The side-open type inner wrench is a blind hole with a depth of 1-4 cm

The side-opening type inner wrench is characterized in that the blind holes are made of hard metal materials, and the wall thickness of the blind holes is 1-3 mm.

The inside of the notch 3 is a square blind hole.

The middle part of the sleeve head 1 is provided with a step.

Has the beneficial effects that:

compared with the prior art, the utility model has the advantages that: the utility model discloses a cover barrel head is U type structure, and it not only can be used for dismantling the very narrow and small or sunken very dark bolt or nut in position, has solved the dismouting difficulty problem when nut one side does not have the construction space moreover, has reduced the work degree of difficulty, has improved production efficiency.

Detailed Description

In order to further understand the features and technical contents of the present invention, the following embodiments of the present invention are further described with reference to the accompanying drawings.

As shown in fig. 1, 2 and 3, the sleeve head device of the socket wrench comprises a sleeve head 1, wherein the sleeve head 1 is provided with a cylinder body, a U-shaped opening 2 is arranged on one side surface of the cylinder body, the depth of a blind hole in the U-shaped opening 2 is 2 cm, and the blind hole can accommodate longer screws. The blind hole in the U-shaped opening 2 is hexagonal or U-shaped and is matched with a nut. The U-shaped opening 2 is downward, and a notch 3 for arranging a power-assisted handle is arranged above the sleeve head 1. The notch 3 can be a square blind hole or other blind hole shapes which can be matched with the power-assisted handle. If the size difference of the matched objects of the U-shaped opening 2 and the notch 3 is large, the middle part of the sleeve head 1 can also be provided with a step, so that the radiuses of the U-shaped opening 2 and the notch 3 are different.

The operation process is as follows:

when a nut without a construction space on one side is installed, the sleeve is sleeved on a matched power-assisted handle (matched with a long connecting rod, a short connecting rod or a universal joint according to the construction space), then the U-shaped opening 2 is sleeved on the installation nut, the matched handle is held by a left hand to keep the sleeve and the nut coaxial, and a screw driver is used by a right hand to disassemble and assemble the screw.
