Description

Technical Field

[0001] The present invention relates to a torsion structure, and more particularly to a torsion structure in which the first body has a relatively large volume and a relatively long length, and has better rotational force when the first body is rotated to adjust the torsion. The palm directly holds and rotates the first body, and the first body is more ergonomic. Background Art

[0002] As previously known, a common torsion structure, such as U.S. Patent No. US8371194B2, Taiwan, China Patent Application No. 099124931, Certificate No. I372097, Patent Name: Torque Measuring Mechanism of a Wrench. The structure of this patent case is as follows: A torque measuring mechanism of a wrench includes: a wrench 10, including a head 12; a handle 13 for holding; a pipe fitting 11, with a long hole 14 provided on the pipe body, one end of which is connected to the handle 13, and the other end is connected to the head 12 through a torque output structure 20; a torque adjusting device 30, including an adjusting knob 31 assembled on the handle 13; a pin 32 installed between the pipe fitting 11 and the handle 13, which can move in the long hole 14 in response to the rotation of the adjusting knob 31; a torque measuring mechanism 50 installed on the wrench 10, including: a measuring cylinder 60 sleeved outside the pipe fitting 11, having a spiral track 61 recessed in the inner wall of the measuring cylinder 60, and the track wall surface contacts the pin 32; several scales displayed on the outer surface of the measuring cylinder 60; a fixing ring 70 installed on the pipe fitting 11, which cooperates with the handle 13 to limit the measuring cylinder 60 to rotate outside the pipe fitting 11 but not displace along the pipe length direction; a sleeve 80 limited outside the measuring cylinder 60, having a window 51 provided at the position of the sleeve 80 facing the scale 54. This is its structure.

[0003] However, the disadvantage of this common torque measuring mechanism of a wrench is that:

[0004] 1. Please refer to the Figure 1 As shown in the Taiwan Gazette of China, the torsion is adjusted by rotating the adjusting knob 31 in terms of structure. However, the size of the adjusting knob 31 is not large, and the adjusting knob 31 can only be held and rotated by the thumb and index finger. That is, it is not easy to exert force on the adjusting knob 31 to adjust the torsion. Especially when the torsion is larger, the elastic element 21 is more compressed, and the greater the force to rotate the adjusting knob 31, the more difficult it is to rotate the adjusting knob 31.

[0005] 2. The adjustment knob 31 is located at the outermost end. Structurally, the fine-tuning window 56 is located near the end, while the other scale 54 is located in the middle. There is a handle 13 between the fine-tuning window 56 and the scale 54, and the handle 13 has a certain length. To determine the torque value, one needs to look at both the fine-tuning window 56 and the scale 54 simultaneously. Since the fine-tuning window 56 and the scale 54 are separated at two places, it is relatively difficult to view the fine-tuning window 56 and the scale 54 simultaneously, and the structure where the fine-tuning window 56 and the scale 54 are separated at two places is not a user-friendly structure.

[0006] 3. Please supplement with the Figure 2 of the Taiwan Gazette of China. The spiral track 61 should be provided on the inner peripheral surface of the measuring cylinder 60. Structurally, the spiral track 61 cannot be made by injection molding. If the spiral track 61 is made by a working mother machine such as lathe machining or milling machining, it is not easy to process the spiral track 61. Moreover, the spiral track 61 is designed to make the distance that the pin 32 moves equal to one full rotation of the ring body 63. Since pi is an irrational number, there will be an error between the distance that the pin 32 moves and the distance of one full rotation of the ring body 63.

[0007] In view of the above-mentioned disadvantages of the conventional structure, the inventor, with years of experience in manufacturing, production, and design in related industries, has finally developed a product with a torque structure that can solve common drawbacks.

[0100] Please refer to Figure 22 as shown in Figure 22 the three-dimensional combination view of some components of the second embodiment of the present invention. The driving portion 21 has a ratchet wrench structure, a socket wrench structure, or an open-end wrench structure with a four-corner head.

[0101] Please refer to Figure 23 as shown inFigure 23 FIG. Figure 23 is a three-dimensional combined view of some components of the third embodiment of the present invention. The driving part 21 is another torque wrench structure, and the internal ratchet device can be disengaged from the first elastic element 28.

[0102] In another embodiment of the present invention, the first groove 513 is a circular hole shape identical to the second receiving hole 423, and the fourth receiving groove 617 is a circular groove shape with the same diameter as the third receiving groove 611.

[0103] In another embodiment of the present invention, when the control collar 82 is displaced and rotated to the locking position, the first recess 821 is not aligned with the first through groove 711. The first positioning member 72 is pressed against by the inner peripheral surface of the control collar 82 and is clamped at the first through groove 711 and the positioning groove 313, and the first body 10 is thus restricted from rotating by the first positioning member 72, the second locking member 71, and the first locking group 30.

[0104] The advantages of the torque structure of the present invention are as follows:

[0105] 1. The first body 10 has a relatively large volume and length. When rotating the first body 10 to adjust the torque, it has a better rotational force, and the palm can directly hold and rotate the first body 10, which is more ergonomic.

[0106] 2. The first display table 12 and the display group 50 are located at the middle position of the torque structure, and the first display table 12 and the display group 50 are close to each other. When the user holds the first body 10 and rotates to adjust the torque value of the torque structure, the user can more directly view the first display table 12 and the display group 50.

[0107] 3. One end of the first body 10 is provided with the first display table 12. The first display table 12 includes a plurality of scales and is arranged in an interval circular arrangement. The display member 51 is provided with the second display table 511. The second display table 511 includes a plurality of scales arranged in an interval linear arrangement. When the first body 10 drives the adjustment group 40 to actuate, the first display table 12 rotates relative to the third body 61 at the fourth receiving groove 617 to display the torque value. The display member 51 is driven by the adjustment group 40 and linearly displaces within the third body 61. The second display table 511 displaces relative to the first through slot 613 to display the compression degree of the first elastic element 28 to display the torque value. The scales of the first display table 12 and the second display table 511 are respectively arranged in an interval circular arrangement and an interval linear arrangement, which reduces the production cost during manufacturing.

[0108] 4. The second cover 63 displays the value of the first display table 12 aligned with the second through slot 615 to display the torque value. One scale of the second display table 511 is aligned with the indicating portion 621 to display the torque value.

[0109] 5. On one side inside the third accommodation groove 611, there is a sliding groove 612. The display member 51 can slide in the sliding groove 612, and the display member 51 can linearly slide along the sliding groove 612 within the range of the first guide groove 22.

[0110] 6. When the first convex portion 512 is displaced at the first guide groove 22, a relatively large fitting volume can be formed between the display member 51 and the first guide groove 22, and it is less likely for the display member 51 to deviate when linearly displaced.

[0111] 7. The first groove 513 is in the shape of a long hole groove. When the display member 51 and the adjustment group 40 are assembled, the display member 51 can have a space for slightly adjusting its position to solve the uncertain value of the elastic force of the first elastic element 28.

[0112] 8. The first locking member 31 is in the shape of a single element. The first locking member 31 has the advantage of low processing cost, or the first locking member 31 can be directly formed by an injection molding process and then drill the second fixing portion 312.

[0113] 9. The second elastic element 83 is a spring structure. After displacing the third locking group 80 away from the first body 10, the second elastic element 83 can make the third locking group 80 abut against the first body 10.

[0114] 10. If the second fitting portion 91 and the first fitting portion 414 cannot be fitted together, the third body 90 can be slightly rotated by a very small angle, and the adjusting member 41 can be fitted with the second fitting portion 91.

[0115] 11. Please supplement with Figure 12 As shown, the adjustment group 40 is restricted by the first locking group 30, so the adjustment group 40 does not protrude out of the first locking group 30. The fourth body 90 is restricted by the second locking group 70 and does not protrude out. The first body 10 is pivotally arranged on the second body 20 under the restriction of the second locking group 70 and the fourth body 90.

[0116] 12. Please supplement with Figure 12 and Figure 15 Compare, there is no relative displacement between the first body 10, the second body 20 and the third body group 60. That is, regardless of whether the torque value of the torque structure is large or small, the overall length of the torque structure is the same and will not change due to the compression degree of the first elastic element 28.

[0117] 13. When the third locking group 80 rotates to the non-locking position on the first body 10, the third locking group 80 does not restrict the second locking group 70 and the first locking group 30. Rotate the first body 10 so that the first body 10 rotates relative to the second body 20, the first locking group 30, and the third body group 60.
