Description

Torque wrench structure

The present invention relates to a torque wrench structure, and in particular, a positioning member of a torque wrench structure is subject to the elastic restoring force of the second ring body and is then accommodated in the next positioning slot, and a sound entering the positioning slot will occur. That is, the re-accommodation between the positioning member and each positioning slot will generate a prompt sound for understanding the rotation state of adjusting the torque value, and it can also be known that the positioning member has been accommodated in one of the positioning slots.

According to my previous knowledge, the conventional torque wrench structure is also a patent case that I have been assigned, such as US patent case number: US8863624B2, Taiwan patent case application number: 103215530, certificate number: M492808, patent name: with locking device The torque wrench structure of this patent is: a torque wrench with a locking device, which includes: a hollow main rod body 10; a tool member 20; a torque adjusting elastic member 40; a clutch assembly 50; and a The locking device 60 is disposed on the outer periphery of the second end 12 of the main rod body 10 and generates relative axial movement along the main rod body 10 between a locked position and an unlocked position, wherein The locking device 60 includes a metal locking ring 61, a compression spring 62, a metal C-shaped buckle 63, and at least one metal positioning bead 65.

However, the lack of the conventional torque wrench structure lies in:

1. Please supplement Figures 6 to 8 of the U.S. Gazette. When you want to adjust the torque value, move the locking ring 61 in the direction of the adjusting handle 30 to make the locking device 60 slide. To unlocked position In the above, the compression spring 62 is compressed due to the displacement of the locking ring 61, and the C-shaped buckle 63 is engaged with the ring groove 614 to position the locking ring 61 in a non-locking position. The positioning beads 65 are It is not pushed by the pushing surface 612 and corresponds to the inclined surface 616, so that the positioning beads 65 can move between the receiving groove 611 and the positioning groove 13, and the adjusting grip 30 can be opposite to the main rod body 10. Rotate, but when the adjustment grip 30 is rotated relative to the main rod body 10 to adjust the torque value, the adjustment grip 30 is not provided with any prompt sound when it is rotated for the purpose of understanding the torque wrench The current torque value state is not convenient to control the system.

2. The positioning groove 13 is hidden in the adjusting handle 30. When the adjusting handle 30 rotates, the positioning bead 65 may not be aligned with one of the positioning grooves 13. Displacement of the locking ring 61 cannot make the The positioning beads 65 are accommodated in the positioning groove 13, and the locking ring 61 cannot be returned to the locked position, which is inconvenient during operation.

In view of the lack of the conventional structure mentioned above, the inventor has, through years of experience in manufacturing, production, and design in related industries, finally came up with a product that can solve the disadvantages of the conventional torque wrench structure.

The adjusting grip of the conventional torque wrench is not provided with any prompt sound when rotating, for understanding the current state of the torque value of the torque wrench, and the control is not convenient. The positioning member of the torque wrench structure of the present invention is subject to the elastic restoring force of the second ring body and is then accommodated in the next positioning slot, a sound that enters the positioning slot, that is, the positioning member and each positioning A reminder sound will be generated after the re-adaptation between the grooves, so as to understand the rotation state of the torque adjustment value of the first body, and it can be known that the positioning member is already accommodated in one of the positions. groove.

When the control collar is in the non-locking position, the first system can rotate relative to the second body, so that the positioning member can be displaced on the second body and positioned at any positioning slot. When moving from one positioning slot to the next positioning slot, the positioning member is pushed by the outer peripheral surface of the second body to open the second ring body. When the positioning member is aligned with the next positioning slot, the positioning member The positioning member is subject to the elastic restoring force of the second ring body, and when it is accommodated in the next positioning slot, the sound of entering the positioning slot will occur. The re-setting between the positioning member and each positioning slot will generate a prompt. Sound for understanding the rotation state of the first body for adjusting the torque value, and it can also be known that the positioning member is already accommodated in a positioning groove, if the torque wrench structure is adjusted to the required torque value, it is convenient Return the control collar to the locked position.
