Description

a socket wrench

technical field

The utility model relates to a tool, in particular to a socket wrench.

Background technique

At present, the commonly used disassembly and assembly tools are mainly wrenches and sockets, and additional auxiliary tools are added for operation. For example, when disassembling the oxygen sensor on the exhaust manifold of the automobile engine, an open-end wrench is generally used. Due to the relatively small space between the engine exhaust manifold and the radiator, the rotation angle of the open-end wrench is limited. When offset, the open-end wrench may not be inserted in, and the oxygen sensor is installed on the exhaust manifold of the engine. The temperature of the heat shield on the exhaust manifold exceeds 500°C, so the open-end wrench cannot be too close to the exhaust manifold to prevent workers from Being scalded, blocked by the heat shield, when using an open-end wrench to disassemble the oxygen sensor, the contact surface between the open-end wrench and the nut is small, and it is difficult to pull out the nut, resulting in a waste of time. Since the open-end wrench cannot be too close to the exhaust manifold and the contact surface between the open-end wrench and the nut is small, when the open-end wrench is used for assembly, the nut may not be tightened in place.

Most of the traditional sleeves are provided with a positioning hole at one end and a driving seat at the other end. If a traditional sleeve tool is used to disassemble the oxygen sensor on the exhaust pipe of the automobile engine, the wire harness connector on the oxygen sensor will not be able to pass through the sleeve, and is limited by the small diameter of the neck of the traditional sleeve. The surface cannot reach the removal surface of the oxygen sensor, and due to the limitation of the space between the engine exhaust manifold and the radiator, the end of the sleeve cannot be equipped with a post, and the operation is laborious.

Contents of the invention

The utility model provides a socket wrench suitable for disassembling and assembling the oxygen sensor on the exhaust manifold of the automobile engine, so that it can be easily used in the narrow high-temperature space between the exhaust manifold of the automobile engine and the radiator. Connect the nut and disassemble the oxygen sensor.

In order to achieve the above object, the utility model takes the following design scheme:

A socket wrench, comprising a sleeve and a handle connected to the sleeve, the sleeve has a cylinder, the cylinder has a hole through the cylinder, and the side of the cylinder is provided with an opening, The opening penetrates the cylindrical body up and down, and the opening and the hole form a communication structure. The handle is arranged on the side of the barrel, and can be replaced according to the characteristics of the working space to adapt to the working environment.

Preferably, one end of the sleeve is a sleeve end, the inner hole of the sleeve end is a hexagonal hole, the other end of the sleeve is a reaming end, and the diameter of the inner hole of the reaming end is larger than the neck diameter of the oxygen sensor, ensuring It passes through the neck of the oxygen sensor smoothly, and the wire harness will not interfere with the cylinder when the sleeve turns the nut. The diameter of the inner hole at the reaming end of the sleeve is larger than that of the sleeve end, and the inner The hole is concentric with the bore at the sleeve end.

Preferably, the length ratio of the reaming end to the sleeve end is 1-3. This increases the contact area between the sleeve and the disassembly surface of the sensor, making disassembly more convenient.

Preferably, the width of the opening of the sleeve is suitable for the wire harness of the oxygen sensor to pass through, and is smaller than the diameter of the inner hole at the end of the sleeve.

Preferably, the middle part of the handle is bent, and the front and rear parts form two parts with a height difference between the upper and lower parts. More preferably, the front and rear parts formed by bending the middle part of the handle are parallel. In this way, during the process of replacing the engine oxygen sensor, the worker can stay away from the exhaust manifold and perform disassembly work to avoid being scalded.

The socket wrench provided by the utility model can be multi-directionally socketed with nut disassembly and assembly parts through the opening on the cylinder body of the socket, and the force arm is increased through the handle, which is convenient to hold and apply force, and can make the worker replace the engine oxygen During the process of disassembling and installing the sensor, keep away from the exhaust manifold to avoid being scalded. The socket wrench of the utility model can be used for the disassembly and assembly work of machines and equipment which are complex, limited in space and unsuitable for people to approach. By using the utility model, the disassembly and assembly speed of workers can be increased, and the labor intensity of workers can be reduced.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figures 1-4, a socket wrench of the present invention includes a socket 1 and a handle 4, and the cylinder 11 of the sleeve 1 has a hole 12 through the cylinder 11; the side of the cylinder 11 is provided with a An opening 13 with an appropriate width, the opening 13 penetrates the cylinder body 11 up and down, and the opening 13 forms a communication structure with the hole 12 .

One end of the sleeve 1 is the sleeve end 111, and the inner hole of the sleeve end 111 is a hexagonal hole, which is suitable for the nut on the oxygen sensor. The other end of the sleeve 1 is the reaming end 112, and the inner hole of the reaming end 112 is The diameter is greater than the diameter of the neck 5 of the oxygen sensor to ensure that it passes through the neck 5 of the oxygen sensor smoothly, and the wire harness 6 will not interfere with the cylinder 11 when the sleeve 1 turns the nut. The diameter of the inner hole of the reaming end 112 It is larger than the diameter of the inner hole of the sleeve end 111 , and the inner hole of the reaming end 112 is coaxial with the inner hole of the sleeve end 111 . The length ratio of the reaming end 112 to the sleeve end 111 is 2, which increases the contact area between the sleeve 1 and the dismounting surface of the oxygen sensor, making disassembly more convenient.

The handle 4 is located on the side of the cylinder body 11 and can be replaced according to the characteristics of its working space to adapt to its working environment. The middle part of the handle 4 is bent, and the front and rear parts form two parts with a height difference between the upper and lower parts. The front and rear parts formed after the handle 4 is bent are parallel, so that workers can stay away from the exhaust manifold for disassembly and assembly during the process of replacing the engine oxygen sensor. Work to avoid being scalded.

As shown in Figure 4, this embodiment uses the opening 13 of the sleeve 1 and the hole 12 of the sleeve 1 to form a communication structure on the side of the cylinder 11. The width of the opening 13 is greater than the width of the wire harness 6 of the oxygen sensor, so that the oxygen The wire harness 6 of the sensor can pass through the opening 13 of the sleeve conveniently, so that the inner hole of the sleeve end 111 can be conveniently socketed with the nut of the oxygen sensor. Using the handle 4, the worker can directly pull the handle 4, which is convenient to hold Apply force, away from the exhaust manifold, convenient for workers who disassemble and install the oxygen sensor.
