Description

Torque wrench structure

The invention relates to a torque wrench structure, in particular to a torque wrench structure in operation, when the control collar is hit, the control collar is subjected to a force in the opposite direction to the driving part, and the driving part is in the opposite direction. The force system cannot move the control collar to the non-locking position, which is more secure.

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. In the non-locking position, the compression spring 62 is compressed due to the displacement of the locking ring 61, so that the C-shaped buckle 63 is engaged with the ring groove. 614, the locking ring 61 is positioned in a non-locking position, but the torque wrench structure is displaced to the part being rotated when rotating, and the locking ring 61 is easy to knock when the torque wrench structure is displaced. To other objects, when the lock ring 61 is bumped, the force of the bump is the direction of the lock ring 61 toward the adjustment handle 30, that is, when the lock ring 61 is bumped, the lock will make the lock The fixing ring 61 is automatically shifted to the non-locking position, and the adjusting grip 30 of the torque wrench structure can have a function of adjusting torque without safety.

2. The positioning bead 65 is not pushed by the abutting surface 612 and corresponds to the inclined surface 616, so that the positioning bead 65 can move between the receiving groove 611 and the positioning groove 13, and the adjusting grip 30 is Can be rotated relative to the main lever body 10, but when the adjustment grip 30 is rotated relative to the main lever body 10 to adjust the torque value, the adjustment grip 30 is not provided with any prompt sound when rotating To understand the current state of the torque value of the torque wrench, it is not convenient to control the system.

3. 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 problem to be solved by the invention: In the conventional torque wrench structure, when the torque wrench structure is displaced, the locking ring is easy to bump into other objects, and the force of the collision is the locking ring to the Adjusting the direction of the grip and automatically shifting it to the non-locking position is not safe. In the torque wrench structure of the present invention, when the torque wrench structure is in operation, when the control collar is bumped, the control collar is subjected to a force in the opposite direction to the driving part, and the force in the opposite direction to the driving part cannot make the The control collar moves to the non-locking position, and the movement of the control collar toward the driving part is more secure.

Technical means for solving the problem: The present invention relates to a torque wrench structure, which includes: a first system is provided with a receiving groove, a first through groove and a first ring groove; a second system is provided with a drive And a plurality of positioning grooves; a control collar is sequentially provided with the first peripheral surface, the first tapered groove, the second peripheral surface, and the second tapered groove; a first ring system is sleeved on the first At the first ring groove of a body, the first ring system is hidden inside the control collar, and the first ring system is slightly outwardly elastic; a positioning member is accommodated at the first through groove, and the positioning The pieces are hidden inside the control collar.

Contrast the effect of the prior art: the control collar is moved to the unlocking position on the first body toward the driving part, that is, the control collar is moved toward the driving part, and the torque wrench structure is operating At this time, the torque wrench structure shifts the driving part toward the workpiece, and sometimes causes the control collar to bump into other objects during the shift. When the control collar is bumped, the control collar is subject to The force in the opposite direction to the driving part cannot force the control collar to move to the unlocked position, and it is safer to move the control collar toward the driving part. When the control collar is moved to the non-locking position on the first body toward the driving portion, the elastic element is compressed by the first abutment edge, and the first ring system is stretched outward and top. Abutting the second tapered groove, the control collar is positioned in the non-locking position, and the hand does not need to be pushed against the control collar at all times. When the first ring is stretched outside and abuts against the second tapered groove, the first ring The outer ring of the ring will have a sound, and the control loop is determined to be in the non-locking position according to the sound of the first ring body.
