Description

Torsion structure This invention relates to a torsion structure. A first body and a second body are assembled together, and the assembly length between the first and second body assemblies remains constant, providing sufficient length for gripping. An actuating adjustment assembly can drive a locking assembly to rotate and linearly displace within the second body assembly, allowing the locking assembly to directly or indirectly adjust the compression degree of the elastic element assembly to adjust the torque. As we previously know, the commonly used torsion structure, such as Taiwan Patent Application No. 109144829, patent certificate No. I748804, is similar to US Patent 11203101B1, a torsion structure. This patented structure includes: a first body assembly; and a second body assembly, the second body assembly having the function of torsion release. The second body assembly is assembled, pivotally mounted, or fixedly mounted with the first body assembly, and the first body assembly may shift or not shift relative to the second body assembly. The displacement, the second body assembly includes a second body, a driving head, a top abutment assembly, a plurality of first beads, a set of rings and a plurality of second rings; the second body assembly is assembled, pivotally assembled or fixedly assembled with the first body assembly, the second body assembly is partially housed within the first body assembly, the second body assembly is provided with a third receiving groove, the second body is provided with a plurality of receiving bead grooves, each receiving bead groove is in communication with the third receiving groove, the second body assembly is provided with two second ring grooves, and the plurality of receiving bead grooves are provided between the two second ring grooves; The drive head is pivotally mounted to the second body, and is located at the other end opening of the third receiving groove. The drive head protrudes from the second body and is located away from the first body assembly. The abutment assembly is received within the third receiving groove and includes a first abutment member. The plurality of first beads are received in the bead receiving grooves, each bead receiving groove receiving at least one first bead, one end of which abuts against the first abutment member. The collar is sleeved on the second body, and a fourth receiving groove is provided inside the collar. The second body is provided with a plurality of bead-receiving grooves hidden within the fourth receiving groove, which passes through the collar and is circular in shape. The other end of each first bead abuts against the fourth receiving groove, i.e., each first bead abuts against the top abutment and the fourth receiving groove. The second ring system is fitted into the second ring groove, slightly protruding from the second ring groove, and abuts against the end of the collar, so that the collar system is restricted by the two second rings and cannot be detached from the second body. The second ring system is circular in shape. However, the deficiency of this conventional torsion structure lies in: 1. The second body assembly has the function of torque jump-off. The second body assembly is pivotally connected to the first body assembly. When the first body assembly rotates and rotates relative to the second body assembly, the length of the connection structure between the first body assembly and the second body assembly will become shorter. When the first body assembly and the second body assembly reach the shortest combination structure length due to torque adjustment, the maximum torque value will be achieved. The overall length is relatively short, which is not conducive to rotating with large torque. 2. The rotational displacement of the first body assembly relative to the second body assembly causes the locking assembly to move. The locking assembly presses against the elastic element assembly to adjust the torque. However, there is no structural design between the first body assembly, the second body assembly, and the locking assembly that allows for fine adjustment of the elastic element assembly. The torque can only be adjusted by rotating the first body assembly relative to the second body assembly. The user must continuously adjust back and forth to achieve the desired optimal torque value. 3. As shown in Figure 12, when the first body group rotates relative to the second body group, the first body group is provided with a first mark arranged in a ring, and the second body group is provided with a second mark arranged in a straight line. It is necessary to directly observe the relative position of the first mark and the second mark at the middle of the torsion structure to determine the torque value of the torsion structure. This method of observing the torque value by alignment is rather troublesome. In view of the shortcomings of conventional torsion structures, the inventor, with many years of experience in manufacturing, production, development and design in related industries, has finally developed a torsion structure product that can solve the drawbacks of conventional structures. In conventional torsion structures, the length of the assembly between the first and second body groups is shortened. The maximum torque value is achieved when the shortest possible assembly length is reached by adjusting the torque. However, the overall short length is unfavorable for generating large torques. In this invention's torsion structure, the first and second body groups are assembled, and the assembly length between them remains unchanged, providing the user with sufficient length for gripping. Actuating the adjustment group causes the locking group to rotate and linearly displace within the second body group, allowing the locking group to directly or indirectly adjust the compression of the elastic element group to adjust the torque. This invention relates to a torsion structure, comprising: a first body assembly including a first body; the first body assembly having a first receiving groove, a space, and a notch; a second body assembly having a torsion release function; an elastic member assembly housed in the third receiving groove, the second body assembly also having a torsion release function; a locking assembly partially housed in the third receiving groove, one end of the locking assembly directly or indirectly abutting against the elastic member assembly, the locking assembly being rotatable within the second body assembly and its total length adjustable to directly or indirectly adjust the compression degree of the elastic member assembly; a display meter housed within the space; and an adjustment assembly operable to a locked or unlocked state to control the rotation or non-rotation of the locking component, wherein when the adjustment assembly is in an unlocked state relative to the second body assembly, the adjustment assembly drives the locking assembly to operate. The first body and the second body are assembled in a fixed structure, and the assembly length between the first body assembly and the second body assembly remains unchanged, providing sufficient length for the user to grip the torque-bearing structure. Actuating the adjustment assembly causes the locking assembly to rotate and linearly displace within the second body assembly, allowing the locking assembly to directly or indirectly adjust the compression of the elastic element assembly to adjust the torque. Actuating the adjustment member disengages the first limiting member from the first limiting portion, making the adjustment member rotatable. Rotating the adjustment assembly causes the second limiting member to rotate, displacing the second screw to adjust the compression of the elastic element assembly to adjust the torque. In the first position, the first limiting member is positioned between the first limiting portion and the third limiting portion, and the adjustment member is locked and cannot rotate due to the constraints of the first limiting member and the second body. When the adjustment member moves to the second position, the first limiting member disengages from the first limiting portion, causing the locking member to rotate.

When the adjusting assembly 60 is rotated, the second limiting member 63 drives the locking member 41 to rotate, so that when the second screw 43 is displaced, the compression degree of the elastic member assembly 30 is adjusted to adjust the torque. 4. When the adjusting member 61 is in the first position, the first limiting member 62 is disposed between the first limiting part 212 and the third limiting part 612. The adjusting member 61 is restricted by the first limiting member 62 and the second body 21 and is locked and cannot rotate. When the adjusting member 61 is moved to the second position, the first limiting member 62 is disengaged from the first limiting part 212. The adjusting member 61 is no longer restricted by the first limiting member 62 and the second body 21 and is in a rotatable state. The adjusting group 60 is in an unlocked state. The adjusting group 601 rotates to drive the locking member 41 to rotate. 5. Whether the adjusting member 61 is in the locked or unlocked state, the second limiting member 63 is assembled between the fourth limiting part 614 and the second limiting part 412.

The second bead 64 and the third elastic element 65 are restricted by the locking member 41 and do not come out of the second through hole 616. 8. As shown in Figure 20, a tool extends through the third through hole 72, the third threaded part 411, the fifth threaded part 422, and the non-circular groove. The tool can rotate the second screw 43 to adjust the position of the second screw 43 relative to the first screw 42 to fine-tune the total length of the elastic element assembly 30. The first elastic element 33 and the second elastic element 34 are slightly different in each batch. Fine-tuning the position of the second screw 43 allows for more precise fine-tuning. 9. The plurality of ring bodies 45 can roll smoothly between the third ring groove 413 and the first ring groove 2141, so that the locking member 41 can reduce frictional resistance and make linear displacement smoother when rotating in the third receiving groove 211. 10.

In the first position, the first limiting member is positioned between the first and third limiting portions, and the adjusting member is locked and unable to rotate due to the constraint of the first limiting member and the second body. When the adjusting member moves to the second position, the first limiting member disengages from the first limiting portion, and the adjusting member is no longer constrained by the first limiting member and the second body, becoming rotatable. The adjusting assembly is then unlocked. In the locked and unlocked states, the second limiting member is a long rod-shaped member, longer than the first limiting member. Whether locked or unlocked, the second limiting member is always positioned between the fourth limiting part and the second limiting part. When the adjusting member is unlocked, its rotation causes the adjusting member and the second limiting member to rotate together with the locking member. The second bead and the third elastic element are housed within the second through hole. The second bead is positioned in one of the fourth annular grooves by the elastic force of the third elastic element. The second bead and the third elastic element have the function of positioning the adjusting member assembly. The second bead and the third elastic element are restricted by the locking member and do not dislodge from the second through hole. The torsion structure as described in claim 13, wherein, A second coupling is provided, which is housed in the fifth receiving groove. The second coupling is assembled with the locking member. Due to the restriction of the second coupling, the adjusting assembly cannot disengage from the locking assembly. One end of the second coupling is provided with an eighth threaded portion, which is threaded with the third threaded portion. A third through hole is provided at the axis of the second coupling. The third through hole communicates with the third threaded portion, the fifth threaded portion, and the seventh threaded portion. A tool can be inserted through the third through hole so that the tool can rotate the second screw to adjust the position of the second screw relative to the first screw, thereby fine-tuning the total length of the elastic member assembly. The torsion structure as described in claim 11, wherein, Two third couplings are provided. The two third couplings are inserted into the two first limiting grooves and respectively assembled at the two second limiting grooves. The two third couplings are used to assemble the first body group and the second body group together. The first body group and the second body group are fixed together. The third couplings also close the second limiting grooves so that the plurality of ring bodies do not come out.
