For reference, the description of the present invention has been described with reference to the arrangement state of the configuration shown in FIG. For example, in FIG. 4, the downward direction becomes the downward direction and the upward direction becomes the upward direction. However, the box wrench according to an embodiment of the present invention may be arranged in various directions as necessary.

The box wrench 100 according to an embodiment of the present invention (hereinafter referred to as 'the present box wrench 100') relates to a box wrench 100 usable in two units. The box wrench 100 is mainly used in two units of bolts or nuts used in the test equipment, but the scope of application is not limited thereto and may be variously applied as necessary in addition to the test equipment. Hereinafter, the configuration in relation to the present box wrench 100 will be examined.

This box wrench 100 includes a body portion (1).

1, 2 and 4, the body portion 1 forms a coupling groove 11 on the upper surface to be coupled to the handle 3 to be described later. The coupling groove 11 has the same central axis as the central axis of the body portion 1 so that the torque of the handle 3 is correctly transmitted. In addition, the coupling groove 11 may be formed in a size corresponding to the coupling portion of the handle (3). By way of example, when the coupling groove 11 and the handle 3 are not securely coupled, the transmission of the correct torque is not made, which may lead to a large accident when combining or disassembling the structure of the precise structure.

For reference, referring to FIG. 1, the handle 3 may be coupled to the coupling groove 11 of the body portion 1 and may have a mechanical structure to transmit torque. By way of example, the handle 3 may be formed to transmit power only in one direction of the left or right side according to the set direction using the mechanical gear and the spring structure therein. This allows the operator to deliver the correct torque without the need for great force.

In addition, the present box wrench 100 includes an insertion groove 13.

Insertion groove portion 13 is formed by applying the specifications of the bolt so that the bolt head or nut is inserted. For example, the bolt applied to the insertion groove 13 refers to a hexagonal bolt having a hexagonal head shape, and can be largely standardized into two types. One is the metric bolt specification and the other is the inch bolt specification. Metric bolts are in millimeters (mm) and are distinguished by prefixing the outer diameter value with the letter M. On the other hand, the inch bolt is a unit (inch) and distinguished by displaying the outer diameter value in fractions. As such, the metric bolt and the inch bolt cannot have the same size because they have different units, and the outer diameter of the bolt and the size of the bolt head are formed differently. Therefore, tools with metric bolt specifications are used for bolts and nuts to which the metric bolt standard is applied, and only tools with inch bolt specifications can be used for bolts and nuts to which the inch bolt specification is applied.

2 to 4, the insertion groove 13 is formed by recessing in the upper direction from the lower surface of the body portion 1. In this case, the insertion groove 13 includes a first insertion groove 131 to which the standard of the metric bolt is applied, and a second insertion groove 133 to which the standard of the inch bolt is applied.

More specifically, the body portion 1 has the same central axis as the central axis of the body portion 1, the first insertion groove 131 to which the standard of the metric bolt is applied to each rotate so as to have an angle difference with respect to the central axis And a second insertion groove 133 to which the size of the inch bolt is applied. here, The angle difference may be arranged so as to be spaced apart from each other so that the corner of the inner surface of the first insertion groove 131 and the corner of the inner surface of the second insertion groove 133 do not overlap each other when the body portion 1 is viewed from the bottom surface.

For example, the first insertion groove 131 and the second insertion groove 133 may be formed by rotating at an angle of 15 degrees in different directions, respectively.

In addition, the first insertion groove 131 and the second insertion groove 133 may be formed to have a size corresponding to each other.

The corresponding size may be a size in which the size of the metric bolt applied to the first insertion groove 131 and the size of the inch bolt applied to the second insertion groove 133 are close to each other. For example, when the size of the metric bolt inserted into the first insertion groove 131 is M6 (6 mm), the size of the inch bolt inserted into the second insertion groove 133 may be 1/4 inch (6.35 mm) close to 6 mm. May be). Also, when the size of the metric bolt inserted into the second insertion groove 133 is M10 (10 mm), the size of the inch bolt inserted into the second insertion groove 133 may be 3/8 inch. This prevents the length of the other corner from becoming too short if the size of either the first insertion groove 131 or the second insertion groove 133 is too large, so that the bolt or nut can be disassembled or assembled efficiently. To be able.

Referring to FIG. 4, the first insertion groove 131 and the second insertion groove 133 may be formed at different depths to distinguish the unit specifications. More specifically, when the bolt head is inserted into any one of the first insertion groove 131 or the second insertion groove 133 having different depths, the operator may change the current bolt according to the depth of the bolt head inserted into the insertion groove. The unit size of the insertion groove in which the head is inserted can be measured. In this case, the depths of the first insertion groove 131 and the second insertion groove 133 may be changed as necessary.

3, the dimensions of the metric bolt and the inch bolt inserted into the first insertion groove 131 and the second insertion groove 133 may be marked on the bottom surface of the body part 1. More specifically, the dimension of the metric bolt may be marked on one corner of the regular hexagon representing the first insertion groove 131, and the dimension of the inch bolt may be marked on one corner of the regular hexagon representing the second insertion groove 133. Through this, the user can see the dimensions displayed on the lower surface of the body portion 1 to check the bolts or nuts according to the dimensions can be eliminated the inconvenience of having to check the dimensions separately. In addition, it is possible to prevent the use of bolts and nuts of similar dimensions to prevent damage to the inner surface of the insertion groove (13).

Thus, according to the present invention, by having one box wrench 100 that can be applied to two units, it is possible to reduce the number of tools provided in half can have an economic effect of saving the tool purchase cost. In addition, it is possible to shorten the preparation and cleaning time of the work, and do not have to replace the box wrench 100 according to the unit, thereby improving work progress speed and work efficiency.

While the present invention has been particularly shown and described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And all changes and modifications to the scope of the invention.
