Description

Torsion structure

The present invention is related to a torsion structure, in particular, in a torsion structure, the collar is sleeved on the second body, the collar has a larger inner diameter relative to the second body, and the first bead system is hidden In the collar, when the first bead is disposed between the abutment group and the collar, the first bead can have a larger outer diameter, and the abutment group is displaced in the third receiving groove It can be more effective in rolling friction.

According to our previous knowledge, the conventional torque structure, such as US Patent No. 5,503,043, the structure of the patent is: a torque wrench 10, the torque wrench 10 includes a grip 20 and an acting end 10, the grip 20 is a rod-shaped body for holding and rotating, the acting end 10 has a torsion release function, the acting end 10 is pivoted to the grip 20, and the acting end 10 is partially accommodated in In the handle 20, one end of the acting end 10 is provided with a driving portion 12, and the driving portion 12 is protruding out of the handle 20, and the acting end 10 is provided with a first receiving groove 17 in which the first containing The groove 17 is in the shape of a round groove;

An elastic element 24 is inserted through the handle 20 and the first accommodating groove 17, one end of the elastic element 24 is elastically pressed into the handle 20, and the handle 20 can act against the The end 10 is rotated and displaced to adjust the compression degree of the elastic element 24 to adjust the torque value of the torque wrench 10;

A trip element 25, the trip element 25 is accommodated in the first container 17, the The elastic element 24 elastically abuts between the handle 20 and the tripping element 25. The tripping element 25 can be displaced in the first accommodating groove 17, so that the acting end 10 has a torsion tripping effect. Each of the two sides of the element 25 is provided with a containing hole, the containing hole is aligned with the inner peripheral surface of the first containing groove 17, and the containing hole is in the shape of a groove;

Two beads 30, the bead 30 is accommodated in the cavity of the jumper element 25, the bead 30 is slightly protruded outside the cavity, and one end of the bead 30 abuts against the first cavity The inner peripheral surface of the groove 17 makes the trip element 25 have a rolling friction effect relative to the acting end 10 when it is displaced in the first receiving groove 17.

But the shortcomings of this conventional torsion structure are:

1. As shown in Figures 1 and 2 of the bulletin, the bead 30 is accommodated in the cavity of the trip element 25, and one end of the bead 30 abuts in the first cavity 17 On the peripheral surface, limited by the inner diameter of the first receiving groove 17 and the outer diameter of the trip element 25, the bead 30 cannot be too large, and the bead 30 can be accommodated in the trip element 25 and The rolling friction effect of the beads 30 between the first receiving grooves 17 is poor.

2. The number of the beads 30 is only two, and each bead 30 and the first container 17 are in a point contact structure.

3. The bead 30 should be combined with the trip element 25 and then be accommodated in the first container 17, and as shown in FIG. 1, the bead 30 and the trip element 25 are assembled in the first container. The inside of the container 17 has to slide for a certain distance, but sometimes the bead 30 will disengage from the jumping element 25 during the sliding, and the bead 30 will fall into the first container 17, and the bead 30 and the trip element 25 are more troublesome when they have to be taken out and then put back into the combination.

In view of the lack of the above-mentioned conventional structure, the inventor has spent many years engaged in related industries With its manufacturing, production and design experience, a product with a torque structure that can solve the drawbacks of conventional use is finally available.

In the conventional torsion structure, limited by the inner diameter of the first pocket and the outer diameter of the trip element, the bead cannot be too large, and the bead can be accommodated in the trip element and the first container. Between the grooves, the ball has a poor rolling friction effect. The collar is sleeved on the second body, the collar has a larger inner diameter relative to the second body, the first bead system is hidden in the collar, and the first bead is provided on the abutment group When it is between the ring and the collar, the first bead can have a larger outer diameter, and when the abutting group is displaced in the third receiving groove, the rolling friction effect can be more effective.

A torsion structure includes: a first body group; a second body group, the second body group has the function of torsion, the second body group includes a second body, a driving head, a Abutting group, a plurality of first beads and a set of rings; the second system is provided with a third receiving groove and a plurality of bead receiving grooves; the driving head is pivotally arranged with the second body; the abutting group is containing Set in the third receiving tank, the abutting assembly includes a first abutting member; the plurality of first bead systems are accommodated in the bead-containing tank, and one end of the first bead abuts against the first abutting member The collar is sleeved on the second body, the collar is provided with a fourth receiving groove, the other end of each first ball is attached to the fourth receiving groove, that is, each first The bead system abuts between the abutting member and the fourth container.

The collar is sleeved on the second body, the collar has a larger inner diameter relative to the second body, and the first bead system can protrude outside the bead receiving groove. Concealed in the collar, when the first bead is arranged between the abutting group and the collar, the first bead can have a larger outer diameter, and the abutting group is in the third receiving groove It has more rolling friction effect when it is internally displaced.
