Description

Torsion structure

The present invention is related to a torsion structure, especially a torsion structure in which a fine adjustment function is provided between the fifth screw part and the first screw part to fine-tune the position of the first body, and the third screw part is connected to the The third body, the first screw element and the second screw element have fine-tuning functions to fine-tune the position of the adjustment group. The fine-tuning functions at the two places have their own fine-tuning purposes and have their own functions.

According to our previous knowledge, the conventional torque structure, such as US patent case number: US8245606, Taiwan patent certificate number: M374933, patent name: torque wrench structure that can be accurately set, easy to read and prevent accidental touch to ensure torque value, the The structure of the patent case is: a torque wrench structure that can be accurately set, easy to read, and prevents accidental touch to ensure the torque value. It extends into the front section of the casing, the middle section of the pulling body is pivoted at the head end of the casing, and the rear section of the casing is provided with a jumping mechanism, a torque display tube, a screw hole seat and a handle in sequence, and a torque adjustment mechanism is arranged in the handle. The knocking part of the pulling body and the pushing member of the jumping mechanism are pivotally connected to the two ends of the link piece, the pushing member is sleeved with the shaft holder and the spring thimble, and then the pogo pin is sleeved on one end of the compression spring to compress the The other end of the spring is provided with a spring washer, and the spring washer is provided with a steel ball. The steel ball is in contact with the end face of the screw rod of the torque adjustment mechanism. The screw is screwed in or out by the runner of the torque adjustment mechanism, and the compression spring is squeezed or loosened to adjust the compression. The elastic force of the spring is set to a predetermined torsion force, which is characterized in that the pusher of the jumping mechanism is on the same side as the knocking part Two rolling elements are pivoted at the position of the casing, and the two rolling elements are used to roll on the inner wall of the casing, so that the pushing element can slide straightly.

However, the conventional torque wrench structure that can be accurately set, easy to read, and prevent accidental touches to ensure the torque value is lacking in:

1. As shown in Figure 4, Figure 5 and Figure 17 of the Taiwan Gazette, the figure numbers in the US case and the Taiwan case are slightly different, the joint part 45 is in the shape of a hexagonal head, and the joint hole 46 is in the shape of a twelve Slot-shaped, the coupling hole 46 is fitted with the coupling portion 45, so that the runner 42 drives the screw 41 to rotate. This is the principle of adjusting the torque, but the torque wrench structure needs to be adjusted in two places when it leaves the factory. Adjustment, that is, the alignment on the scale and the zeroing of the compression spring 36, and the alignment of the two places with each other, only the rotation of the screw 41 by the runner 42 is only convenient to zero the compression spring 36, but it is difficult to make the scale also There is only one adjustment structure for alignment, the alignment of the scale and the zeroing of the compression spring 36, and there are two difficulties in the adjustment.

2. The joint portion 45 has twelve angles that can be fitted with the joint hole 46. However, when the compression spring 36 leaves the factory, each compression spring 36 cannot be fixed, and the compression value of each compression spring 36 is omitted. There is an error. After the compression spring 36 is assembled in the sleeve 20, the screw 41 needs to be rotated at this time, so that the compression degree of the compression spring 36 is slightly different, so that each compression spring 36 is close to the standard value, but After the screw 41 is rotated, the angle of the coupling part 45 and the coupling hole 46 is wrong, and the coupling part 45 and the coupling hole 46 cannot be fitted together. However, after the screw 41 is rotated, the compression degree of the compression spring 36 also changes, that is, the lack of both is caused. There are only twelve angles between the coupling portion 45 and the coupling hole 46 that can be fitted together. Insufficient.

In view of the lack of the above-mentioned conventional structure, the present inventor has been engaged in related industries for many years With the experience in manufacturing, production and design, finally a product with torsion structure that can solve the conventional drawbacks came out.

In the conventional torque wrench structure that can be accurately set, easy to read, and prevent accidental touches to ensure the torque value, there is a dilemma in the adjustment of the adjustment structure in which the scale alignment and the compression spring must be zeroed and only one place is required. In the torsion structure of the present invention, there is a fine adjustment function between the fifth screw part and the first screw part to fine-tune the position of the first body, the third screw part is connected to the third body and the first screw part. There is a fine-tuning function between the combination piece and the second screw-joint piece to fine-tune the position of the adjustment group. The fine-tuning functions of the two places have their own fine-tuning purposes and have their own functions.

The invention relates to a torsion structure, which comprises: a first main body is provided with a first accommodating groove and a first screwing part; a second main body is provided with a driving part; an elastic element; an adjustment group system A third screwing part is provided; a third body assembly includes a second seat body, a third body, a first screwing part and a second screwing part; the second seat system is provided with a fifth screw The joint part is screwed with the first screw joint part, the second seat system is provided with a first tooth part; the third body system is provided with a first sleeve part, a second tooth part, a third contact surface, a first accommodating groove, a fourth contact surface and a through-hole groove, the second tooth portion is engaged with the first tooth portion; the first screw element is screwed with the third screw portion; The second screw part is screwed with the third screw part.

The fifth screwing part is screwed inside the first screwing part and is displaced to the positioning position, that is, there is a fine adjustment effect between the first body and the third body set, The first body has the function of fine-tuning alignment. There is a fine adjustment function between the third screw part, the third body, the first screw element and the second screw element, and the adjustment group has a fine adjustment function to adjust the torque value of the elastic element. There is a fine adjustment function between the fifth screwing part and the first screwing part to fine-tune the position of the first body, the third screwing part and the third body, the first screwing part and the second screw There is a fine-tuning function between the combined parts to fine-tune the position of the adjustment group. The third body group has two fine-tuning functions, and the two fine-tuning functions have their own fine-tuning purposes and have their own functions.
