Description

Technical Field

[0001] The present invention is related to a torsion structure, and in particular to a torsion structure in which the limiting group rotates on the second body to a non-limiting position or a limiting position, so that the third body is in a non-limiting state or a limiting state relative to the second body, so as to control whether the third body has a torsion jump effect relative to the second body. The torsion structure has two different operating effects and is operationally expandable. Background Art

[0002] As previously known, the common torque structure is also a patent case assigned by me, such as US patent case number: US8863624B2, Taiwan patent case application number: 103215530, certificate number: M492808, patent name: torque wrench with locking device, the patent case structure is: a torque wrench with a locking device, which includes: a hollow main rod body 10; a tool part 20; an adjustment handle 30; a torque adjustment elastic member 40; a clutch element 50; and a locking device 60, which In the figure, when in the locked position, the positioning bead 65 is pushed by the push surface 612 and can be pressed against the positioning groove 13 to limit the rotation of the adjustment handle 30 relative to the main rod body 10. When in the unlocked position, the C-shaped buckle 63 is engaged with the annular groove 614, so that the positioning bead 65 can move between the accommodating groove 611 and the positioning groove 13, so that the adjustment handle 30 can rotate relative to the main rod body 10, and the locking ring 61 can make a sound when adjusting and switching between the locked position and the unlocked position. This is the structure.

[0003] However, the disadvantages of this common torque wrench with locking device are:

[0004] Please supplement with the communiqué Figure 3 As shown, when the locking device 60 is located in the locking position, the adjustment handle 30 rotates about its own axis to drive the main rod body 10 and the tool piece 20, so that when the main rod body 10 and the tool piece 20 rotate about themselves as the axis, the clutch element 50 makes the tool piece 20 have a torque jump effect relative to the main rod body 10, but the torque wrench structure is not provided with any control structure to limit the effect of the clutch element 50, so that the torque wrench structure only has a torque effect, and its expandability is insufficient.

[0070] In another embodiment of the present invention, the present invention lists that the first body 10 rotates and shifts relative to the second body 20 to adjust the torque, and there is another structure in which the first body 10 and the second body 20 are fixed to each other, and the rear end of the first body 10 is provided with an adjustment structure to adjust the torque. There are many basic structures of the torque structure that cannot be described in detail one by one. Therefore, as long as the first limiting member 81 and the second limiting member 82 are provided between the second body 20 and the third body 60, they should all fall within the protection scope of the present invention.

[0071] The advantages of the torsion structure of the present invention are:

[0072] 1. The limiting group 80 can be rotated on the second body 20 to a non-limiting position or a limiting position, so that the third body 60 is in a non-limiting state or a limiting state relative to the second body 20, so as to control whether the third body 60 has a torque jump effect relative to the second body 20. The limiting group 80 is located at the non-limiting position, and the torque structure has a torque wrench effect. When the limiting group 80 is located at the limiting position, the third body 60 is limited by the limiting group 80, and the top portion 65 cannot swing and displace. The third body 60 does not have a torque jump effect relative to the second body 20, and the torque structure can be operated as a general wrench structure. The torque structure has two different effects and is operationally expandable.

[0073] 2. The limiting group 80 can be rotated on the second body 20 to a non-limiting position or a limiting position, so that the third body 60 is in a non-limiting state or a limiting state relative to the second body 20, so as to control whether the third body 60 has a torsional release effect relative to the second body 20, and has expandability.

[0074] 3. The first limiting member 81 can rotate on the second body 20 so that the second limiting member 82 is aligned with the second limiting portion 811 or the third limiting portion 812, so that the second limiting member 82 is not stuck or is stuck at the first limiting portion 64, so that the third body 60 is in a non-restrictive or restrictive state relative to the second body 20. The torque structure is a torque wrench structure or a general wrench structure for operation.

[0075] 4. The limiting group 80 can be rotated on the second body 20 to a non-restricted position or a restricted position, so that the third body 60 is in a non-restricted state or a restricted state relative to the second body 20. The first limiting member 81 is rotated on the second body 20 so that the second limiting portion 811 and the third limiting portion 812 are respectively aligned with the limiting groove 23, so that the second limiting member 82 is against the second limiting portion 811 or the third limiting portion 812, so that the second limiting member 82 is not stuck or is stuck at the first limiting portion 64.

[0076] 5. The positioning bead 83 is accommodated in the first groove 24 and the first through hole 814. When the first limiting member 81 rotates on the second body 20, the positioning bead 83 rolls on the first groove 24. The first through hole 814 can be aligned with the first positioning portion 241 or the second positioning portion 242. The positioning bead 83 is positioned and accommodated in the first positioning portion 241 or the second positioning portion 242, so that the first limiting member 81 is positioned in the non-restricted position or the restricted position. The positioning bead 83 has the function of positioning the first limiting member 81.

[0077] 6. The elastic body 84 is in the shape of an elastic ring and is accommodated in the second groove 813. The elastic body 84 presses against the positioning bead 83 so that the positioning bead 83 is hidden in the first limiting member 81. The elastic body 84 provides elastic resistance when the positioning bead 83 rolls on the first groove 24.

[0078] 7. The control group 80 only includes the first limiting member 81, the two second limiting members 82, at least one positioning bead 83 and the elastic body 84. The control group 80 has a simple structure and can be in a non-limiting shape or a limiting shape and has a positioning function.

[0079] 8. When the first limiting member 81 is rotated to the non-restrictive position on the second body 20, the second limiting portion 811 is aligned with the limiting groove 23, the second limiting member 82 protrudes and abuts against the second limiting portion 811, the first limiting portion 64 is not restricted by the second limiting member 82, and the third body 60 is not restricted by the limiting group 80. The third body 60 is in a non-restrictive state relative to the second body 20, the first through hole 814 is aligned with the first positioning portion 241, and the positioning bead 83 is positioned and accommodated in the first positioning portion 241, so that the first limiting member 81 is positioned in the non-restrictive position, and has the effect of torque escape.

[0080] 9. When the first limiting member 81 is rotated to the limiting position on the second body 20, the third limiting portion 812 is aligned with the limiting groove 23, and the second limiting member 82 is pressed by the third limiting portion 812 and abuts against the first limiting portion 64, so that the third body 60 is restricted by the limiting group 80. The third body 60 is in a limiting shape relative to the second body 20, and the first through hole 814 is aligned with the second positioning portion 242. The positioning bead 83 is positioned and accommodated in the second positioning portion 242, so that the first limiting member 81 is positioned at the limiting position, and the third body 60 does not have a torque jump effect relative to the second body 20.

[0081] 10. When the control collar 31 is in the unlocked position, the first body 10 can rotate relative to the second body 20, so that the positioning member 34 can be displaced on the second body 20 and positioned at any positioning groove 25. When the positioning member 34 moves from one positioning groove 25 to the next positioning groove 25, the positioning member 34 is pushed by the outer peripheral surface of the second body 20 to open the second ring body 35. When the positioning member 34 is aligned with the next positioning groove 25 again, the positioning member 34 is received by the elastic restoring force of the second ring body 35 and is accommodated in the next positioning groove 25 again, a sound of entering the positioning groove 25 is generated. When the positioning member 34 is accommodated between each positioning groove 25 again, a positioning prompt sound is generated to understand the rotation state of the adjustment torque value of the adjustment member 50. It can also be known that the positioning member 34 has been accommodated in one positioning groove 25. If the torque structure has been adjusted to the required torque value, the control collar 31 can be conveniently returned to the locked position.

[0082] 11. When the positioning member 34 is accommodated in the positioning groove 25 again, it is the elastic restoring force of the second ring body 35. The positioning member 34 is accommodated with the limitation of the elastic restoring force of the second ring body 35. The displacement path of the positioning member 34 is carried out according to the arc surface of the positioning groove 25. Therefore, the sound of the positioning member 34 being accommodated again is more reliable. When the positioning member 34 is displaced, it is limited by the second ring body 35 and the sound can also be smoother.

[0083] 12. The positioning slot 25 is hidden in the first body 10, so the positioning member 34 can be known to be accommodated in the positioning slot 25 of the required torque value by the sound, which is more practical to judge by the sound during operation.

[0084] 13. When the control collar 31 moves on the first body 10 in the opposite direction of the second body 20 to the unlocked position, the second elastic member 32 is pressed by the second abutting edge 312 and becomes compressed, and the first ring body 33 expands outward and presses against the second conical groove 316, so that the control collar 31 is positioned in the unlocked position. The hand does not need to push the control collar 31 all the time, and the hand can rotate the first body 10 conveniently. When the first ring body 33 expands outward and presses against the second conical groove 316, the first ring body 33 expands outward and makes a sound, and the control collar 31 can also be determined to be in the unlocked position based on the sound of the first ring body 33.

[0085] 14. When the first body 10 rotates relative to the second body 20, there is a sound. When the control ring 31 is in the unlocked position, there is also a sound. Both torque adjustment actions produce a sound prompt.

[0086] Therefore, the torsion structure of the present invention has industrial applicability, novelty and advancement, and can truly meet the application requirements for invention patents and can be applied for in accordance with the law.
