Description

Torsion structure

The present invention is related to a torsion structure, especially a torsion structure, under the action of the elasticity of the first washer, the second body and the locking part are pushed away from each other, so that the fixing part is pressed against the first On the surface and the second surface, the gap between the second body and the locking member can be eliminated, so that the torsion structure has the dual effects of easy assembly and gap elimination, and has the best of both worlds.

According to our previous knowledge, the conventional torsion structure, such as U.S. Patent No.: US6463834B2, the structure of this patent is: a torque wrench 10, and this torque wrench 10 is composed of:

A first body 20, one end of the first body 20 is provided with a driving part 21 in the shape of a square head;

A second body 30, the second body 30 is pivoted with the first body 20, the first body 20 is partly accommodated at one end of the second body 30, and the driving part 21 is protruded from the first body Outside the two main bodies 30, the second main body 30 is in the shape of a hollow round rod, and the outer peripheral surface of the other end of the second main body 30 is provided with a plurality of positioning parts 33, and the plurality of positioning parts 33 are connected with the first main body 20. Far away from each other, the plurality of positioning parts 33 are arranged in a ring shape with the axis of the second body 30, each positioning part 33 is in the shape of a concave arc groove, and the second body 30 is provided with two fixing parts 34, Each fixing portion 34 is in the shape of a circular perforation;

An elastic member 50, the elastic member 50 is accommodated in the second body 30, the elastic member 50 is bounced between the first body 20 and the second body 30, so that the first body 20 has a torsion spring The effect of getting rid of;

A fixing base 74, the fixing base 74 is fixed with the second body 30 and hidden in the second body 30;

A plurality of fixing parts 75, the fixing parts 75 are located at the fixing part 34 and the fixing seat 74, so that the fixing seat 74 is fixed with the second body 30, and the fixing parts 75 are in the shape of a round tip or a bead body shape.

But the lack of this customary torsion structure is:

1. The plurality of fixing parts 75 are assembled on the fixing part 34 and the fixing seat 74. The fixing parts 75 commonly used in the industry are in the shape of pins or beads. If the fixing parts 75 are pins as shown in Figure 2 Body shape, the fixing part 75 needs to be assembled on the fixing part 34 and the fixing seat 74 by external force, that is, the three are in a tight fit structure, and there is no relative tolerance between the second body 30 and the fixing seat 74 , the rotation and adjustment torque of the screw rod 70 will be more reliable, which is its advantage, but the external force assembly such as the oil pressure assembly of the fixing member 75 is to use other machines, which is more labor-intensive and it is necessary to purchase the machine. Its shortcoming, if this fixing member 75 is bead body shape, the hole of this fixing part 34 and this fixing seat 74 can be slightly larger than this fixing member 75 outer diameter, promptly is loose fitting between the three, and this fixing member 75 is It is an advantage that it is directly placed in the hole of the fixing part 34 and the fixing seat 74 without using external force to assemble, but there will be a tolerance after the second body 30 and the fixing seat 74 are assembled. When 70 rotates, there will be a lack of tolerance in the adjustment torque, and another lack will occur. This fixing member 75 uses the tip body or the pearl body and there are respective lacks, and there is no way to have the best of both worlds.

2. The screw rod 70 and the fixing base 74 are combined and then accommodated in the second body 30, the fixing The second body 30 and the fixing seat 74 are easily connected to the third body 60 by pressing the two fixing parts 75 at the same time. Assembling, it is more troublesome to need second-hand and use when assembling, if there are three fixing parts 75, it is more troublesome to assemble the fixing parts 75.

In view of the lack of the above-mentioned conventional structure, the inventor has been engaged in the manufacture, production and design of related industries for many years, and finally a product with a torsion structure that can solve the conventional disadvantages comes out.

In the conventional torsion structure, the tip body or the bead body of the fixing part has its own shortcomings, and it is impossible to have the best of both worlds. In the torsion structure of the present invention, under the elastic action of the first washer, the second body and the locking piece are pushed apart so that the fixing piece is pressed against the first surface and the second surface, so that The gap is eliminated between the second body and the locking member, so that the torsion structure has the dual functions of easy assembly and gap elimination, and has the best of both worlds.

The present invention relates to a torsion structure, which includes: a first body part is provided with an accommodating groove; a second body part is provided with a driving part, a plurality of first fixing parts and a first end surface; an elastic member; a The locking group includes a locking piece, a plurality of fixing pieces and a first washer; the locking piece is provided with a first pivot, a plurality of second fixing parts and a second end surface; the fixing piece is assembled on the first fixing part and the second fixing part, so that the locking part is combined with the second body; the first washer is fitted on the locking part, the first washer is elastic, and the first washer is elastic between the first end surface and the second end surface, so that the second The body and the locking part push against each other, and the first washer can reduce the gap between the locking part and the second body.

The first fixing part, the second fixing part and the fixing part are in a loose fitting structure, so the plurality of fixing parts can be conveniently assembled, and the first washer is resilient against the first end surface and the second Between the end faces, under the action of the elasticity of the first washer, the second body and the locking part are pushed away from each other, so that the fixing part is pressed against the first face and the second face, so that the second The gap between the main body and the locking part is eliminated. Under the elastic action of the first washer, the torsion structure has the dual functions of easy assembly and gap elimination, and has the best of both worlds.
