Description

Torque wrench

The present invention relates to a torque wrench, in particular, a wrench tool of a mechanical torque measuring mechanism, and the torque wrench is designed to have a dodge space for preventing scale wear.

According to the technical field of mechanical assembly, bolts and nuts are used to lock various components, which is a relatively well-known fixing method. However, because each person's feeling of strength is not the same, and some special combinations are not as tight as possible, so there is a torque wrench to ask the market, so that every screw lock operation, even in different people Under the operation, the same torque requirement can also be achieved; the wrench is designed such that the front end of the handle has a head that can be inserted with the screw, thereby applying a torque to the handle to generate a torque to drive the head to screw the screw into the object. In the body, the threaded portion of the screw and the locked object generate a gripping force to fix the two objects to each other. However, when the user operates the wrench, the subjective force can only be exerted by the usual operation experience. Those who are familiar with this operation will use different force, which will naturally affect the fixed strength and produce unpredictable results. Therefore, some operators have designed a torque wrench that can preset the torque value and has a warning function; among them, the torque One type of wrench is a purely mechanical design. When the user applies a force close to the preset torque value, the torque wrench will generate a swinging feel to remind the user.

In general, mechanical torque wrenches have a rotating handle that can be rotated relative to the main body of the wrench. The displacement is adjusted to adjust the internal spring pressure to control the number of pounds of torque, and the main system of the wrench is formed with a pair of torsion pounds, and the displacement alignment is interpreted by the rotation of the handle; however, the traditional mechanical torque wrench is After long-term use, the scale on the main body of the wrench is easily peeled off due to the friction of the rotating handle, which affects the user's interpretation.

In view of this, the creator has been engaged in the development of related industries for many years, and has in-depth discussions on the problems faced by the existing mechanical torque wrenches, and actively seeks solutions. After long-term efforts and research, he has finally succeeded in creating. A wrench tool of a mechanical torque measuring mechanism is provided, and the torque wrench is designed to have a dodging space for preventing scale wear.

The present invention relates to a wrench tool for a mechanical torque measuring mechanism, and the torque wrench is designed to have a dodge space for preventing scale wear.

In order to achieve the above-mentioned creative purpose, the "torque wrench" of the present invention comprises a main body of a wrench and a rotating handle; the end of the main body of the wrench is a working head, and the other end is sleeved with a rotating handle, and the inside of the wrench body is provided with a The torsion bounce mechanism, the rotation handle is rotated relative to the main body of the wrench, and the set pounds of the torsion bounce mechanism is controlled, and the end of the rotation handle and the wrench body is defined as a pair of end edges, and the wrench body is compared The end edge displacement range is formed with a concave section, and the wrench body is formed with a torsion graduation of the fluorescent material in the concave section.

In this way, through the rotation of the rotating handle relative to the main body of the wrench, the rotating body is displaced relative to the main body of the wrench to compress or release the torsion bounce mechanism, thereby setting the torque warning value, and the opposite end edge of the rotating handle is located on the torsion scale according to the displacement effect. The position allows the operator to easily interpret the currently set warning torque value, and the torque scale is formed in the concave section, which can effectively avoid the situation that the torque scale is rubbed by the rotating handle.

The rotating handle is formed near the edge of the edge to form a scale with a fluorescent material.

It can be seen from the above-mentioned creations that the "torque wrench" of the present invention has a torque for setting the torsion force of the torsion bounce mechanism, so that the operator can accurately reach the preset torque requirement when performing each lock operation; The torsion graduation is formed in the concave section of the wrench body, which can effectively avoid the situation that the torsion scale is rubbed by the rotating handle; therefore, the novel can be said to be a practical and progressive creation, which is quite worthy of promotion by the industry. And publicized to the public.

The third figure is a partial enlarged schematic view of the torque wrench after the adjustment of the handle.

The present invention relates to a wrench tool for a mechanical torque measuring mechanism, and the torque wrench is designed to have a dodging space for preventing scale wear. Please refer to the first to third figures, the new "torque wrench" includes There is a handle body 1 and a handle 2; the end of the wrench body 1 is a working head 11, the working head 11 is a ratchet wrench head, and the other end is sleeved with the rotating handle 2, and the wrench body 1 is internally provided with a a torque bounce mechanism (not shown), the rotary handle 2 is rotationally displaced relative to the wrench body 1, and the set pounds of the torsion bounce mechanism is controlled, and the end of the rotary handle 2 overlapping with the wrench body 1 is defined as a comparison The end edge 21, the wrench body 1 is formed with a concave section 12 in the displacement range of the opposite end edge 21, and the wrench body 1 is The concave section 12 is formed with a torsion graduation 13 of a fluorescent material.

Thus, the rotation of the shank 2 relative to the wrench body 1 is performed by the rotation of the shank 2 relative to the wrench body 1 to compress or release the torsion bounce mechanism, thereby setting the torque warning value, and the opposite end edge 21 of the shank 2 is displaced. The influence is on the position of the torsion scale 13 so that the operator can easily interpret the currently set warning torque value, and the torsion scale 13 is formed in the concave section 12, which can effectively avoid the situation that the torsion scale 13 is rubbed by the rotating handle 2. .

Further, the rotary handle 2 is formed near the end edge 21 to form a ratio of the fluorescent material to the scale 22; the alignment scale 22 and the torsion scale 13 have alignment adjustment characteristics, so that the operator can be more precise. Control the torque value.

In the embodiment, the concave section 12 is represented in a more obvious manner, and does not limit the depth of the concave section 12 in practical application, that is, it is formed into a depth of only 1 mm by precision machining, and only needs to conform to the creation. As a dodge of wear and tear, it is the protection of this new type.

It can be seen from the above-mentioned creations that the "torque wrench" of the present invention has a torque for setting the torsion force of the torsion bounce mechanism, so that the operator can accurately reach the preset torque requirement when performing each lock operation; The torsion graduation is formed in the concave section of the wrench body, which is more effective in preventing the torque scale from being rubbed by the rotating handle.

The above list is only for explaining the preferred embodiment of the novel creation, and it is not intended to impose any form restrictions on the creation, so that all the creations in the same creative spirit are related to the creation of the novel. Any modification or change, which is otherwise achievable and has the same effect, should still be included in the scope of this new creative intent.

In summary, the "torque wrench" of the new creation is indeed practical in terms of structural design and practical use, and the disclosed structure is also unprecedented. Innovative structure, so its "novelty" should be undoubtedly considered, and this new creation can be more effective than the conventional structure, so it is also "progressive", which fully complies with the provisions of the new patent application of the Chinese Patent Law. Therefore, in accordance with the law, the company has filed a patent application with the bureau, and urged the bureau to grant the patent right in the case as soon as possible.
