Description

Easy to assemble torque wrench

The present invention relates to an easily assembled torque wrench, and more particularly to an innovative structural type revealer having a magnetic member.

Pressing, the torque wrench uses the spring force of the coil spring to generate the torque, so that the user can adjust the compression amount of the coil spring by adjusting the mechanism, and then adjust the torque wrench to the required torque value.

Generally speaking, the torque wrench is designed to have a tripping component. When the torque is greater than the pressure set by the coil spring, the tripping component will be disengaged and an audible sound will be given to the user; as shown in Fig. 9, generally The two ends of the tripping member 91 of the torque wrench 90 are respectively abutted against the concave portion of the bottom surface of the end of the rod body 92 and the concave portion of the abutting member 93. In this assembly, the tripping member 91 is usually placed first. The recess of the bottom surface of the end of the rod 92 is assembled into a tube 94 together with the rod 92.

However, since the size of the trip member is small and is assembled after being placed in the recess of the rod body, it is easy to fall due to shaking of the user's hand, which is rather inconvenient to assemble and relatively increases the assembly time.

Therefore, in view of the problems existing in the above-mentioned conventional torque wrench structure, how to develop an innovative structure that is more ideal and practical, and the users are looking forward to it, and the relevant operators must make efforts to develop the breakthrough goal and direction; Therefore, the creator has been engaged in the manufacturing development and design experience of related products for many years, and specifically aims at the above objectives.  After the design and careful evaluation, the original creation is practical.  

The main purpose of this creation is to provide a torque wrench that is easy to assemble. The technical problem to be solved is to make an innovative breakthrough in how to develop a new type of torque wrench structure that is more ideal and practical.

Based on the foregoing objective, the present invention provides a torque wrench that is easy to assemble, and includes: a tubular body having a working head at a front end thereof and a grip at a rear end, the working head extending to the rear end a rod body, and a bottom surface of the rod body is recessed with a first recess; an abutting member is disposed in the tube body and located at a rear end of the rod body, and the abutting member has a direction toward the rod body a front end surface of the rod body, wherein the front end surface is recessed with a second recess; a tripping member is disposed between the rod body and the abutting member, and the two ends of the tripping member respectively abut against the first portion a concave portion and the second concave portion; a magnetic member is disposed on the first concave portion of the rod body and one of the jumping members, and the magnetic member magnetically attracts the jumping member by its magnetic attraction force In the rod body; a coil spring is disposed in the tube body; an adjustment mechanism is disposed in the tube body and located at a rear end of the tube body for adjusting the compression amount of the coil spring; The coil spring is disposed between the abutting member and the adjusting mechanism.

With this innovative and unique design, this creation can be compared with the prior art, and the jumper has the advantages of being easy to fall off and practical progress in assembly.

Please refer to Figures 1, 2, 3, and 4 for a preferred embodiment of the torque wrench that is easy to assemble. However, these embodiments are for illustrative purposes only and are not limited by this structure. .

The easy-to-assemble torque wrench comprises: a tubular body 10 having a working head 11 at its front end and a grip 12 at the rear end, the working head 11 extending to a rear end of the rod 13 and The bottom surface of the rod body 13 is recessed with a first recessed portion 14; an abutting member 20 is disposed in the tube body 10 at the rear end of the rod body 13, and the abutting member 20 has a The front end surface 21 of the rod body 13 is recessed with a second recess 22; a tripping member 30 is disposed between the rod body 13 and the abutting member 20, and the tripping member The two ends are respectively abutted in the first recessed portion 14 and the second recessed portion 22; a magnetic member 40 is attached to the tripping member 30, and the magnetic attracting member 40 is caused by its magnetic attraction force. The tripping member 30 is magnetically positioned on the rod body 13; a coil spring 51 is disposed in the tube body 10; an adjusting mechanism 52 is disposed in the tube body 10 and located in the tube body 10 a rear end for adjusting a compression amount of the coil spring 51; further, the coil spring 51 is disposed at the end  Between the connector 20 and the adjustment mechanism 52.  

In more detail, the rod body 13 and the tripping member 30 are magnetically conductive metals (such as ferrous metals) that are magnetically attracted, and the magnetic member 40 is a magnet.

In this example, the tube body 10 is a circular-diameter tube, and the tripping member 30 is recessed toward one end of the first recess portion 14 to define a cylindrical first group of holes 31. The magnetic member 40 is a cylinder. And being disposed in the first set of holes 31, and the top surface of the magnetic member 40 is flush with the end surface of the tripping member 30, so that the tripping member 30 is magnetically positioned in the first recess of the rod body 13. 14 in.

As shown in Figures 5 and 6, it is a second embodiment of the present invention, wherein the tubular body 10 is an equal diameter circular tube, and the bottom surface of the first concave portion 14 of the rod body 13 is recessed with a cylindrical shape. The second set of holes 15 is formed in the second set hole 15 and the top surface of the magnetic member 40 is flush with the bottom surface of the first recess 14 to make the jump. The member 30 is magnetically positioned in the first recess 14 of the shaft 13.

Therefore, the magnetic attraction force of the magnetic member 40 is used to position the tripping member 30 in the first concave portion 14 of the rod body 13, which can solve the disadvantage that the tripping member 30 is easy to fall during the assembly process, and is effective. Improve assembly efficiency.

Of course, the magnetic component 40, the first set of holes 31 and the second set of holes 15 are assembled, and in addition to the combination of the cylindrical shapes, other shapes can be designed.

As shown in Figures 7 and 8, it is a third embodiment of the present invention, wherein the front portion of the tubular body 10 is a flat tubular body, and the rear portion is an equal diameter circular tube, and the jumping member 30 abuts against the first The first end of the recessed portion 14 is recessed in a cylindrical shape. The magnetic member 40 is cylindrical and disposed in the first set of holes 31, and the top surface of the magnetic member 40 is The end face of the trip member 30 is flush (that is, the design of the magnetic member 40 is the same as in FIG. 3). Of course, the front portion is a flat tube body 10, and the magnetic member 40 can also be designed to be disposed on the first recess portion 14 of the rod body 13, so that the trip unit 30 is magnetically attracted to the first portion. In the recess 14 (that is, the design of the magnetic member 40 is the same as that of the fifth embodiment, the bottom surface of the first recess 14 of the rod 13 is provided with a cylindrical second group of holes 15, and the magnetic member 40 is The cylinder is disposed in the second set of holes 15).

In more detail, the present embodiment is characterized in that when the tripping member 30 needs to be replaced due to the adjustment of the corrected torque value, the magnetic head can be simultaneously positioned in the first recessed portion 14 by simply disassembling the working head 11. The unloading member 30 is taken out, and the magnetic attraction is utilized at the time of assembly to achieve the advantage of being difficult to fall off, and the disadvantage that the assembly process of the prior art is easy to fall is solved.

In addition, in each of the above embodiments, the first recessed portion 14 and the second recessed portion 22 are square holes, and the tripping member 30 is a square block corresponding to the square hole; of course, in practice, the shape thereof It can also be designed according to the needs of users.
