Description

Torsion structure

The present invention relates to a torsion structure, especially in a torsion structure, when the positioning member moves from one positioning groove to the next positioning groove, the positioning member is re-accommodated in each position by the elastic restoring force of the elastic body. A sound will be emitted when a positioning slot is made, and a prompt sound will be generated between the positioning piece and each positioning slot.

According to our previous knowledge, the conventional torque structure, such as Taiwan Patent Application No.: 096217159, Certificate No.: M333999, Patent Name: Adjustable Torque Wrench Structure (1), the patent case structure is: an adjustable torque wrench Structure (1), comprising: a main rod 10 and an elastic body 14, an accommodating space 11 is formed inside the main rod 10, and a stop 16 is provided at the end of the accommodating space 11, so that the elastic body 14 is accommodated in the accommodating space 11 The space 11 is opposite to the blocking portion 16, and the outer edge of one end of the main rod 10 is radially provided with a positioning pin 12; a guide member 20 and a guide block 25, the guide member 20 is accommodated in the main rod 10 In the accommodating space 11 of the rod 10, one end of the guide member 20 is formed with a top stop 22 for blocking the elastic body 14, and the guide member 20 is internally provided with a guide groove 21 for accommodating a guide block for guiding and sliding. 25, wherein the radial position of the outer edge of the guide block 25 is provided with a positioning hole 27 corresponding to the positioning pin 12 of the main rod 10, so that the positioning pin 12 of the main rod 10 can be guided and inserted into the positioning hole 27 of the guide block 25 to achieve mutual positioning. , and the center of the guide block 25 is provided with an internal thread section 26, the other end of the guide member 20 is provided with a combination hole 23, and the other end surface of the guide member 20 is provided with a plurality of fixing grooves 24; a rod sleeve 30 , a linkage member 33 and an adjustment portion 34. One end of the rod sleeve 30 is rotatably covered on the main rod 10, and the other end is relatively fixed with a linkage member 33. The linkage member 33 is provided with a joint portion. 362, and the joint portion 362 provides a fixed adjustment portion 34, the adjustment portion 34 is formed with an outer thread segment 35 that is just screwed to the guide block 25, and a combination segment 36 is formed adjacent to the outer thread segment 35, wherein the combination segment 36 The coupling hole 23 is provided for pivoting on the guide member 20, the other end of the link member 33 is provided with a pin hole 38, and the other end of the adjusting portion 34 is provided with a limiting portion 37, and the outer edge of the limiting portion 37 is provided with an external thread; a The limiting device 50 includes a knob 51 and a fixing pin 54, wherein the knob 51 is provided with a limiting hole 52, and the limiting hole 52 is formed with an inner thread which is relatively screwed to the limiting portion 37 of the link member 33, The fixing pin 54 is correspondingly disposed in the pin hole 38 of the linking member 33, and the fixing pin 54 is relatively blocked against the knob 51, so that the front end of the fixing pin 54 is convexly set in the fixing groove 24 of the guiding member 20, so that The rod cover 30 is locked so that the functional state of rotation cannot be given.

However, the lack of this conventional adjustable torque wrench structure (1) lies in:

1. To adjust the torque value of the torque wrench, rotate and displace the knob 51 to disengage the fixing pin 54 from the fixing groove 24. The rod sleeve 30 and the link 33 are not limited by the guide. The moving member 20 and the guide block 25 rotate the rod sleeve 30, the rod sleeve 30 and the limiting member 40 are integrally linked with the linking member 33 to rotate, and the linking member 33 drives the guide member 20 to push against the The elastic body 14 is used to adjust the length of the elastic body 14 to adjust the torque, but the torque wrench structure does not have any structure that can emit a prompt sound when rotating, so as to know the current torque value of the torque wrench structure, control The above is not convenient.

2. To lock the rotary adjustment function of the rod cover 30, the knob 51 should be rotated first, so that the limiting hole 52 spirals forward relative to the limiting portion 37, so that the washer 53 passing through the adjusting portion 34 is screwed forward. The two fixing pins 54 are forced to move forward, so that the two fixing pins 54 are inserted into the fixing groove 24, the guide member 20 is radially restricted by the guide block 25 and cannot rotate, and the linking member 33, The rod sleeve 30 also cannot be rotated, but the guide member 20 needs to be milled with the guide groove 21 and drilled with a plurality of fixed grooves 24. The guide member 20 has a relatively large diameter. big cost.

In view of the above-mentioned shortcomings of the conventional structure, the inventor of the present invention has finally developed a product with a torsion structure that can solve the drawbacks of the conventional structure with years of experience in manufacturing, production and design in related industries.

The problem to be solved by the invention: There is no structure in the conventional torque wrench structure that can emit a prompt sound when rotating, so as to know the current torque value of the torque wrench structure, and it is not convenient to operate.

The parts abut against or disengage from each other; there is a rotating piece, which is assembled with the handle and the plurality of locking pieces, the rotating piece is half-protruded outside the handle, and one end of the rotating piece is fixed There is a fourth screwing part, the fourth screwing part is screwed with the third screwing part, the fourth screwing part can be helically displaced in the third screwing part, the fourth screwing part is In the shape of an external thread, the rotating part is provided with a second abutting part, and the other end of each locking part is abutted on the second abutting part, when the fourth screwing part is screwed inside the third screwing part and During displacement, the rotating member restricts or does not restrict the locking member, so that the locking member abuts against or disengages from the first abutting portion to be in a locked state or an unlocked state, and the second abutting portion is set at the The fourth screw One end of the joint; the rotating member is rotated and displaced, and the locking member is driven by the rotating member to move in the direction of the opening of the second accommodating groove synchronously in the first through slot and the first through hole, so that the locking member is Abutting against the first abutting portion, the handle is restricted by the second fixing group and the locking member and cannot rotate, and the torsion structure is in a locked state and cannot adjust the torque; rotating the rotating member makes the first The four screwing parts are screwed in the opposite direction of the opening of the second accommodating groove in the third screwing part, the locking part is not restricted by the rotating part, and the locking part can be disengaged from the first abutting part , the handle and the locking piece are not limited by the second fixing group and can be rotated on the first body, and the torsion structure is in an unlocked state and can adjust the torsion force. The torsion structure according to claim 1, wherein the positioning member is in the shape of a metal ball, and the elastic system is a spring structure. The torsion structure according to claim 1, wherein the driving part is in the shape of a hexagonal slot or a square head, and the handle rotates with its own axis to drive the first body and the second body, so that the When the second basic system rotates with itself as the axis, the second basic system has the effect of torsion escape.
