Description

A wrench connecter

The present invention relates to a wrench connecting rod, and more particularly, to a wrench connecting rod used when a bolt or a nut is connected to a wrench when tightening or loosening.

In general, a wrench is a tool used for tightening or loosening a bolt or a nut. The wrench is usually formed with a rectangular or hexagonal groove and has a socket portion into which a bolt head or a nut is inserted. And an operating portion.

When a bolt or nut is loosened by using such a wrench and the bolt or nut is located in a narrow space such as a vehicle interior, a wrench is used because the bolt or nut can not be tightened or unscrewed by a conventional wrench alone. In such a wrench connecting rod, a fitting protrusion is formed at one end to be fitted into the axial groove of the rear surface of the socket portion, and at the other end, a fitting groove is formed in which the rotary shaft of the rotary actuating portion is inserted.

On the other hand, bolts and nuts are tightly tightened, which may require greater force when loosened. In such a case, conventionally, a bolt or nut is loosened more easily by using a rotating shaft having a larger diameter. In this case, an adapter having a groove with a larger diameter is inserted in the fitting groove of the wrench connecting rod.

However, when the adapter is used as described above, the loss of force is greater than when a single tool is used. In other words, since the force is not transmitted directly due to the frictional force generated on the connection portion of the adapter and the wrench connecting rod, in case of the manual wrench, the operator has to apply a large force to unscrew the bolt and nut. there is a problem. In addition, since a large force is concentrated on the connection portion, the fitting groove of the connection block is worn out, so that the adapter and the wrench connecting block are damaged and can not be used.

Korean Registered Utility Model No. 20-0357030

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a bolt or nut for a bolt or a nut, which is capable of using a larger diameter rotary shaft without a separate adapter It is possible to reduce the loss of power by using a single tool while reducing the cost of purchasing the adapter, thereby providing an impact on the bolt or nut with less power and less power consumption, thereby providing a wrench connector that can be released more easily .

According to a feature of the present invention, a socket portion 2 having an insertion groove in which a bolt head or a nut is inserted is formed on the front surface and a shaft groove 2 is formed on the rear surface, And a rotary operation part (3) which is fitted in the socket part (1) and which rotates the socket part (1) so that the socket part (1) tightens or loosens the bolt head or the nut. 3, the wrench connecting rod 10 includes a rod-like body 11 and a pair of wedge-shaped bodies 11 integrally provided at one end of the body 11, And a fitting groove 13 which is integrally formed at the other end of the body 11 and into which the rotary shaft 4 of the rotary operation part 3 of the wrench is inserted Wherein an inner diameter (R2) of the fitting groove (13) is formed to be larger than an outer diameter (R1) of the fitting protrusion (12).

As described above, according to the present invention, the wrench connecting rod 10 mounted between the socket portion 1 and the rotary actuating portion 3 of the wrench is inserted into the outer diameter of the fitting protrusion 12 formed integrally with one end of the body 11 It is possible to increase the inner diameter R2 of the fitting groove 13 formed integrally with the other end of the body 11 with respect to the rotary operation portion 3 having the rotary shaft 4 having a larger diameter without using the adapter Can be directly mounted on the fitting groove 13 of the wrench connecting rod 10.

Accordingly, when a large force is required to unscrew a bolt or a nut, durability is improved because the number of parts is reduced and a large force is applied to a connection part between the adapter and the wrench connecting part, thereby eliminating the problem of wearing. In addition, considering the loss of transmitted force as the number of parts connected to each other is increased, the loss of force is reduced compared with the use of the adapter, so that the operator can easily release the bolt or nut with less force. Power consumption is reduced and efficiency is improved.

1 is a perspective view showing an embodiment of a wrench connecting rod according to the present invention.
Fig. 2 is a view showing the state of use

The objects, features and advantages of the present invention will become more apparent from the following detailed description. Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

1 and 2 are views showing a wrench connecting rod according to a preferred embodiment of the present invention. As shown in the drawing, the wrench connecting rod 10 according to one embodiment of the present invention is mounted between the socket portion 1 of the wrench and the rotary actuating portion 3 for unscrewing a bolt or nut located in a narrow space or the like, The body 11, the fitting protrusion 12 and the fitting groove 13 are integrally formed. At this time, although the rotary operation unit 30 is a manual operation mode in which the operator directly rotates the rotary shaft 4, the rotary operation unit 30 may be an automatic mode in which the rotary shaft 4 is automatically rotated by the motor.

The body 11 is formed in a rod shape, and has various sizes, that is, various diameters and lengths in consideration of the position of the bolt or the object to which the nut is tightened. At this time, the body 11 has the same diameter from one end to the other end, and the other end has an enlarged portion 11a whose diameter is expanded.

The fitting protrusion 12 is integrally provided at one end of the body 11 and is coupled to the socket portion 1 to transmit the rotational force of the body 11 to the socket portion 1 as it is. At this time, the socket portion 1 is formed in a cylindrical shape, and an unillustrated insertion groove into which a bolt head or a nut is inserted is formed on the front surface, and a shaft groove 2 is formed on the rear surface of the socket portion 1 to which the rotary shaft 4 of the rotary operation portion 3 is coupled do. The rotary operation portion 3 can be both of a type in which an operator manually rotates and a type in which the rotary is automatically rotated by a motor. The end face of the fitting protrusion 12 has a shape corresponding to the end face of the shaft groove 2 on the rear face of the socket portion 1. In the illustrated embodiment, the fitting protrusion 12 has a square cross section.

The fitting groove 13 is integrally formed at the other end of the body 11 and is engaged with the rotation axis 4 of the rotation operating portion 3. [ The fitting groove 13 is recessed in the end surface of the body 11 expansion portion 11a and has a cross section corresponding to the cross section of the rotation shaft 4. [ In the illustrated embodiment, it is illustrated that the cross-section of the fitting groove 13 is square, and the square fitting projections 12 and the diagonal lines are formed perpendicular to each other.

The wrench connecting rod 10 according to an embodiment of the present invention is used when the bolt or nut can not be loosened when the socket portion 1 is directly connected to the rotary actuating portion 3. [ That is, when the bolt or nut is located in a narrow place such as inside the vehicle or inside the machine, the socket portion 1 is separated from the rotary operation portion 3 by using the wrench connecting rod 10. Accordingly, the bolt or nut located in the narrow space can easily be tightened or loosened due to the body 11 having a long length of the wrench connecting rod 10.

At this time, the inner diameter R2 of the fitting groove 13 is formed to be larger than the outer diameter R1 of the fitting protrusion 12 as shown in FIG. The inner diameter R2 of each of the square fitting grooves 13 and the outer diameter R1 of each of the fitting protrusions 12 is a length of one side of the square. Figure 2 shows the inner diameter R2 of the fitting groove 13, Are shown together in the same ratio to compare the outer diameter (R1) of the outer ring (12).

This makes it possible to use a rotary shaft 4 having a diameter slightly larger than the diameter of the rotary shaft 4 to be directly connected to the socket portion 1 so that it is larger than the force required for bolt or nut size If force is required, the bolt or nut can be impacted and released more easily. In addition, the number of parts is reduced and the loss of force is reduced compared with the case of using a conventional adapter, so that the bolt or nut can be easily released with less power or less power consumption.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.
