Description

Torsion structure

The present invention is related to a torsion structure, especially in a torsion structure, when the locking group is in the locking position, the first positioning member has the function of positioning, and when the locking group is in the non-locking position, the first positioning The element has a sound, and the first positioning element has two different functions when the first positioning element is in the locking position or the non-locking position, and has a double function.

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 fixing 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 adjustable torque wrench structure that can emit a prompt sound when rotating, so as to know the current torque value state of the torque wrench structure. In the torsion structure of the present invention, when the locking group is in the locking position, the first positioning member has the function of positioning, and when the locking group is in the non-locking position, the first positioning member has a sound, and the first positioning member has a sound. When the device is in the locked position or the unlocked position, it has two different functions and has a double function.

Technical means for solving the problem: a torsion structure, which includes: a first main body with a first accommodating groove; a second main body; an elastic element; a first fixing group; an adjustment group; a second fixing group The set includes a second fixed seat; the second fixed seat is provided with a plurality of locking grooves; a handle is provided with a second accommodating groove; a positioning ring is provided with a plurality of positioning grooves, a first ring groove and a Conical groove; a locking group is assembled with the adjusting group and the positioning ring, the locking group can be actuated to a locking position and an unlocking position, when the locking group is in the unlocking position, the locking The group system drives the adjusting group to rotate to adjust the length of the elastic element and adjust the torque value. When the locking group is actuated to the locking position, the locking group and the adjusting group cannot rotate and the torque value is fixed.

Compared with the effect of the prior art: when the locking group is in the unlocked position, the first When the positioning piece is accommodated in each positioning slot, a sound will be produced, and a prompt sound will be produced between the first positioning piece and each positioning slot. When the torsion structure has been adjusted to the required torque value, the first locking member is pushed, and when the first locking member is displaced to the opposite position between the elastic receiving groove and the conical groove, the first positioning member is subjected to the The elastic restoring force of the elastic body pushes against the conical groove, and the locking group is positioned at the locking position due to the first positioning member. When the locking group is in the locking position, the first positioning member has the effect of positioning. When the locking group is in the non-locking position, the first positioning member has a sound, and the first positioning member is in the locking position or non-locking position. There are two different functions when locking the position, which has a double function.

In order to make the committee members and those skilled in the art fully understand the effect of the present invention, the structure and composition of the present invention are explained in the following in conjunction with the drawings and drawing numbers, but the following descriptions are only used to explain the implementation of the present invention For example, it is not intended to limit the present invention in any form, and any modification and change made under the spirit of the present invention should still belong to the protection scope of the present invention.
