Description

Torque tool

This creative department is about a torsion tool.

Press, the torque tool is available for setting the torque value, so that it can select the appropriate torque setting value according to the assembly and disassembly process of various components. The conventional torque tool is equipped with a working part, a jumper, a pusher and An elastic piece, the tripping piece is clamped between the working part and the abutting piece, and the elastic piece is pushed against the abutting piece to provide a tripping torque value, when the working part is locked When the torsion force is greater than the tripping torque value, the tripping piece will trip off the abutting piece.

However, when the elastic member of the conventional torsion tool is pressed against the abutting member, because the elastic member is imperfectly pressed against the abutting member with a normal stress, the elastic member cannot effectively linearly change when it is compressed and deformed under a force. , Resulting in the inaccuracy of the torque tool, and there are shortcomings that need to be improved.

Therefore, it is necessary to provide a novel and progressive torque tool to solve the above-mentioned problems.

The main purpose of this creation is to provide a torsion tool, the elastic part of the torsion tool is smoothly pressed against the abutting part with a positive stress, so that the elastic part is effectively linearly changed when it is compressed and deformed under a force, so as to increase the torsion force. The accuracy of the tool.

In order to achieve the above purpose, this creation provides a torque tool, which includes a body, a working part, a clutch mechanism and a torque adjustment component.

One end of the clamping member 41 abuts against the elastic member 42, and the other end is provided with a first protrusion 411 and the first protrusion 411 abuts At one end of the abutting member 32 facing the elastic member 42, the elastic member 42 provides a predetermined torque value.

For example, when the head 21 undergoes a locking operation and receives a force, the working rod 22 is driven by the head 21 to swing relative to the body 1, when the force of the head 21 is greater than the preset torque value At this time, the jumper 31 is pushed by the working rod 22 and jumps off with the pusher 32, and the elastic member 42 is pushed by the pusher 32 and is slightly compressed. It is worth mentioning that, since the clamping member 41 of the present creation is provided with the first protrusion 411 and the first protrusion 411 abuts against the abutment member 32, the abutment member 32 can be formed with a single point. The way of contact is against the clamping member 41, and the clamping member 41 can transmit the normal stress to the elastic member 42 in a straight line, so that the elastic member 42 can be smoothly compressed along the linear direction without occurrence Bending, twisting, etc., so that the elastic member 42 can be compressed in a linear state, so as to have a more accurate preset torque value.

Specifically, the working rod 22 is pivotally connected to the body 1 around a first direction L1, the body 1 extends along a second direction L2, the second direction L2 is transverse to the first direction L1, and the first abutting tip 221 and the second abutting top 321 respectively clamp the two ends of the jumper 31 along the second direction L2.

Wherein, the jumper 31 is a rectangular block, the rectangular block extends along the first direction L1, and the rectangular block is provided with four side walls 311. The first abutting top 221 is provided with a first concave arc surface 222, the second abutting top 321 is provided with a second concave arc surface 322, and the two opposite side walls 311 of the rectangular block respectively abut against the first concave arc surface 222 With the second concave arc surface 322, the two side walls 311 are not completely attached to the first concave arc surface 222 and the second concave arc surface 322, so as to make it easier to trip. In other embodiments, the trip The member 31 may also be a ball or other structure.

Furthermore, the elastic member 42 is a coil spring. The elastic member 42 is cut in a plane toward one end of the clamping member 41 and is provided with a cutting end 421, and the cutting end 421 abuts against the clamping member 41 so as to make the The elastic member 42 springs against the clamping member 41 in a linear direction.

In addition, the clamping member 41 has a second protrusion 412 protruding toward one end of the elastic member 42, and the second protrusion 412 extends into the coil spring. In detail, the clamping member 41 includes a plate 413 and a ball 414 that combine to form the first protrusion 411 and the second protrusion 412, and the cutting end 421 abuts against the plate 414. 413 does not abut against the ball 414 to prevent the elastic member 42 from being pushed by the ball 414 to deflect.

It should be noted that the sphere 414 is punched on the plate 413 from the plate 413 toward one side of the abutting member 32, and a part of the plate 413 is transformed into a convex arc section 415 and covered on the sphere 414. In part, when the first convex portion 411 abuts against the abutting member 32, the ball 414 is supported by the convex arc section 415 and will not be displaced or even separated from the plate 413.

The distance by which the first protrusion 411 protrudes from the plate 413 along the first direction L1 defines a first distance D1, and the distance by which the second protrusion 412 protrudes from the plate 413 along the first direction L1 defines A second distance D2. The ratio of the first distance D1 to the second distance D2 is between 1:1 and 1:8, which is 1:5 in this embodiment. The first distance D1 is smaller than the second distance D1. The distance D2 enables the first protrusion 411 to abut against the abutting member 32 more stably.

In summary, the torsion tool of this creation, because the clamping piece of this creation is provided with the first convex portion and the first convex portion abuts against the abutting piece, the abutting piece can be contacted with a single point The method is against the clamping member, the clamping member can transmit the normal stress to the elastic member in a straight line, so that the elastic member can be smoothly compressed in the linear direction without bending, twisting, etc. Therefore, the elastic member can be compressed in a linear state to have a more accurate preset torque value.
