Description

Torsion structure

The present invention is related to a torsion structure, in particular, in a torsion structure, the control member controls the locking member to be displaceable or non-displaceable in the first accommodating groove, so that the locking part is engaged with the ratchet part or can be When the phase is disengaged, only the control part is exposed to the outside, which reduces the change of the locked state due to external force collision.

According to what I have previously known, the conventional torsion structure, such as US Patent No. 4290329, has the following structure:

A rod body 10, the rod body 10 is a square rod shape, the rod body 10 is provided with an accommodating space 11, the accommodating space 11 is in the shape of a square groove, the rod body 10 is provided with a first pivot The first pivotal portion is in communication with the accommodating space 11, the first pivotal portion penetrates the accommodating space 11, and the axis of the first pivotal portion is connected to the accommodating space 11 The axis is perpendicular to each other, the first pivotal portion is in the shape of a circular groove penetrating through it, the rod body 10 is provided with a first set of portions, and the first set of portions communicates with the accommodating space 11 The first set of setting portion is arranged near the first pivoting portion, the first pivoting portion is set between the opening of the accommodating space 11 and the first set of setting portion, and the first set of setting Department is round hole shape;

A body set 20, the body 20 is accommodated in the accommodating space 11, the body 20 is partially exposed out of the rod body 10, and one end of the body set 20 is provided with a driving head 13, the driving head 13 is protruding outside the rod body 10, the other end of the body set 20 is provided with a first body 18 and a second The first body 18 and the second body 19 are parallel to each other. The first body 18 and the second body 19 are accommodated in the accommodating space 11, and the first body 18 and the second body 19 are parallel to each other. A trip unit 23 is provided between the ends of the body 19, and the trip unit 23 can be used for the torque tripping effect when the driving head 13 is rotated to a set torque value. The end of the first body 18 is A first threaded portion is provided, the first threaded portion is aligned with the first pivotal portion of the rod body 10, the first threaded portion penetrates the first body 18, and the first threaded portion penetrates Circular groove shape, the first threaded portion is in the shape of an internal thread;

A torque adjustment group 40, the torque adjustment group 40 is penetrated at the first pivot portion of the rod body 10 and the first thread portion of the first body 18, and one end of the torque adjustment group 40 is provided with an actuator Part 43, the actuating part 43 protrudes out of the rod body 10 for rotation, and rotating the actuating part 43 drives the torsion adjustment group 40 to rotate at the first pivot part and the first threaded part to adjust Torque value

An elastic piece 55, the elastic piece 55 is accommodated in the accommodating space 11, one end of the elastic piece 55 is provided with a second assembly portion 57, the second assembly portion 57 is assembled on the second assembly of the rod body 10 At a set of parts, the second assembly part 57 is slightly protruding outside the rod body 10, the second assembly part 57 is U-shaped, and the other end of the elastic sheet 55 is provided with a set part 58. The sleeve 58 is sleeved on the torque adjustment group 40;

A restricting member 51 is pivoted at the second assembly portion 57. One end of the restricting member 51 is provided with a restricting portion 56. The restricting portion 56 is in the shape of a groove. With inner ring teeth, the restricting portion 56 can be capped and clamped on the actuating portion 43 to restrict the actuating portion 43 from being unable to rotate. The torque adjustment group 40 is restricted by the restricting member 51 and cannot be rotated. The restriction The member 51 can be rotated by an angle with the second assembly portion 57 as the axis, so that the restricting portion 56 is relative to the actuating portion 43 It is in an open or closed shape, so that the torque adjustment group 40 is in an unrestricted shape, which can adjust the torque or a restricted shape, but cannot adjust the torque.

However, the lack of this conventional patent structure lies in:

1. The restricting member 51 can rotate the second assembly portion 57 as an axis to make the restricting portion 56 open or close relative to the actuating portion 43, so that the torque adjustment assembly 40 is in an unrestricted shape or However, the restricting member 51 is arranged on the outside of the rod body 10, that is, regardless of whether the restricting portion 56 is opened or closed relative to the actuating portion 43, it may collide with the restricting member 51 during operation. As a result of lack of operation, when the restricting portion 56 is in a closed shape with respect to the actuating portion 43, if the restricting portion 56 is accidentally disengaged from the actuating portion 43, it is easy to rotate to the actuating portion 43 to change the torque When the restricting portion 56 is open relative to the actuating portion 43, the restricting member 51 is protrudingly provided on the rod body 10.

2. As shown in Figure 2, the restricting member 51 is set on the side of the rod body 10, the right-hand operator holds the rod body 10 with the right hand, and the restricting member 51 faces the operator. The left hand of the operator is convenient to actuate the restricting member 51, but the left-handed operator holds the rod body 10 with his left hand, and the restricting member 51 is not facing the operator, the right hand of the operator must move over the rod body 10 The restricting member 51 is difficult for a left-handed operator to actuate the restricting member 51, and the restricting member 51 is installed on the side of the rod body 10 to have this defect.

In view of the above-mentioned shortcomings of the conventional structure, the present inventor has finally produced a product with a torsion structure that can solve the drawbacks of the conventional structure through years of experience in manufacturing, production and design in related industries.

In the conventional torque structure, it is easy to rotate to the actuating part to change the torque setting value. In the torsion structure of the present invention, the control element controls the locking element to be displaceable or non-displaceable in the first accommodating groove, so that the locking part engages with the ratchet part or can be disengaged, and the control element is only The control part is exposed to the outside to reduce the change of the locked state due to external force collision.
