Description

Torsion structure

The present invention is related to a torsion structure, in particular, in a torsion structure, the plurality of first locking elements are inserted through the first slot, and the plurality of first locking elements bear the rotational force of the first body, the The first locking member has a plurality of systems that can evenly distribute all the rotational forces and have a longer life.

According to our previous knowledge, the conventional torque wrench structure, such as Taiwan patent application number: 096217159, certificate number: M333999, patent name: adjustable torque wrench structure (1), the structure of the patent case is: an adjustable torque wrench The structure (1) includes: 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 The space 11 is relatively stopped at the stop 16, and the outer edge of one end of the main rod 10 is radially provided with a positioning pin 12; a guide 20 and a guide block 25, the guide 20 is accommodated in the main In the accommodating space 11 of the rod 10, one end of the guide member 20 is formed with a top end 22 for blocking the elastic body 14, and the guide member 20 contains a guide groove 21 for accommodating a guide block 25. 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 is 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 coupling hole 23, and the other end of the guide member 20 is provided with a plurality of fixing grooves 24; a rod sleeve 30 , Linkage 33 and adjustment part 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 33, the linkage 33 is provided with a coupling part 362, and the coupling portion 362 is provided with a fixed adjustment portion 34, the adjustment portion 34 is formed with a threaded section 35 that is screwed to the guide block 25, and a coupling section 36 is formed adjacent to the external threaded section 35, wherein the coupling section 36 A coupling hole 23 pivoted to the guide member 20 is provided, the other end of the linkage member 33 is provided with a pin hole 38, the other end of the adjustment portion 34 is provided with a limiting portion 37, and the outer edge of the limiting portion 37 is provided with an external thread; 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 internal thread that is relatively screwed to the limiting portion 37 of the linkage 33, The fixing pin 54 is corresponding to the pin hole 38 of the link member 33 and the fixing pin 54 is relatively blocked by the knob 51. The front end of the fixing pin 54 is convexly set in the fixing groove 24 of the guide member 20, so that The rod cover 30 is locked and cannot be given a rotating function state.

However, the lack of this conventional torsion structure is that when you want to lock the adjustment function of the rod sleeve 30, you need to turn the knob 51 first to make the limit hole 52 spiral forward relative to the limit portion 37, so that The washer 53 of the adjusting part 34 presses the two fixing pins 54 forward, so that the two fixing pins 54 are embedded in the fixing groove 24, and the guide member 20 is limited in the radial direction by the guide block 25 and cannot rotate , And restrict the linkage 33 and the rod sleeve 30 from rotating, but the guide 20 needs to be milled with the guide groove 21 and drilled with a plurality of fixed grooves 24. The guide 20 has a larger cost.

In view of the above-mentioned shortcomings of the conventional structure, the inventors have used years of experience in manufacturing, production and design in related industries to finally have a product with a torque structure that can solve the drawbacks of the conventional structure.

In the conventional torsion structure, the guide part needs to be milled The guide groove is provided and the drill is provided with a plurality of fixed grooves, and the guide member has a relatively high cost. In the torsion structure of the present invention, the plurality of first locking members are inserted through the first through slot, the plurality of first locking members bear the rotational force of the first body, and the first locking members are in a plurality of systems. All the rotational force can be distributed equally.
