Torque wrench anti-off mechanism

The present invention relates to a torque wrench anti-drop mechanism, and more particularly to a situation in which the internal mechanism of the torque wrench is prevented from being broken due to falling or improper operation.

According to Taiwan, Taiwan is an industrial technology kingdom. From manufacturing, processing to maintenance, all of them are technologically advanced and well-made. Therefore, industrial products are deeply loved by countries all over the world, from automobile manufacturing to electronic processing, which bring abundant benefits to the country. The most commonly used equipment in the industry for many operations is hand tools. Although some of the highly technical and hazardous environments have been replaced by machines, the basic processing and maintenance must be completed with the aid of hand tools. Therefore, all countries in the industry are not only developing simpler, more user-friendly and cheaper manufacturing tool structures, in which wrenches are used frequently.

The wrench is designed such that a front end of the handle has a head that can be engaged with the screw, thereby applying a torque to the handle to generate a torque to drive the head to screw the screw into the object, so that the threaded portion of the screw is locked The object creates a gripping force to fix the two objects to each other. However, when the user operates the wrench, the subjective force can only be exerted by the usual operation experience. If the person is not familiar with the operation, the force will be applied. Differently, it also affects the fixed strength and produces unpredictable results. Therefore, some operators have designed a torque wrench that can preset the torque value and has a warning function.

The common torque wrench structure (as shown in FIG. 5) on the market includes: a handle 4 having a screw 41 and a spring 42 mounted on the screw 41, and the screw 41 is at the upper end. An actuating member 43, a resisting member 44 and a tripping member 45 are provided, and the spring 42 is pushed by the spring 42 to push the resisting member 44 by the tripping member between the actuating member 43 and the resisting member 44. 45 increases or decreases its pressure and produces varying degrees of torsion during use.

However, in the above-mentioned conventional, due to the conventional torque wrench structure, the adjustment of the handle 4 can drive the screw 41 to rotate in the handle 4, so that the spring 42 is adjusted to have a different degree of tightness. By increasing or decreasing the pressure of the tripping member 45 between the actuating member 43 and the resisting member 44, different degrees of torque prompting action are generated during use, and the torque wrench may be improperly used or dropped from a height when in use. However, the internal tripping member 45 is displaced and its torque prompting function is unsuccessful, which causes the torque wrench to be replaced or repaired, which is a major drawback, and needs to be improved.

The present invention provides a torque wrench anti-off mechanism, comprising: a grip, the whole is in a tubular hollow state, the outer edge of the grip defines a grip area, and the interior defines a receiving space, and a resisting bolt is arranged at the bottom of the receiving space; a set of adjusting members disposed at the resisting bolt; a joint portion is disposed at the receiving space of the grip; and an actuating portion is provided with a guiding rod The grip accommodates the space and is combined with the joint a pivoting state; and a pulling body disposed at an upper end of the guiding rod; wherein the coupling portion has a resisting member disposed at an upper end of the resisting bolt of the gripping space of the gripper and The adjusting member of the holding space of the grip is in a resisting state, and the resisting member has a positioning area at the upper end thereof; and a retaining member is disposed at the upper end of the resisting member, the retaining member has a through-the-hole a perforation of the upper and lower sides; a tripping member is in a resisting state at a positioning area of the resisting member of the joint portion, and is disposed at a perforation of the retaining member of the joint portion, and the tripping member is integral The hole is smaller than the through hole of the retaining member to present a reserved space; and the actuating member is disposed at the lower end of the guiding rod of the actuating portion, and has a positioning area and is in a state of resisting the jumping piece.

Wherein the jumper of the joint portion is represented by any one of a geometric shape of a cylindrical shape or a polygonal prism shape; wherein a positioning area of the resisting member of the joint portion cooperates with a positioning area of the actuating member of the joint portion, and In the form of the jump piece of the joint portion, the shape of the geometric shape of the cylindrical or polygonal column is presented; wherein the piercing of the joint of the joint portion is matched with the jump piece of the joint portion. The form is represented by any one of a geometric shape of a cylindrical shape or a polygonal column shape; wherein the resisting member is assembled at the resisting bolt in a combination or in a bonding manner to make the adjusting member Restricted to the resisting bolt; wherein the actuating member is disposed at a lower end of the guiding rod in a combination or in a bonding manner; wherein the resisting bolt of the grip adjusts the tightness of the adjusting member Degree to change different torques; Wherein the grip and the actuating part are matched with the locking component by screwing or by the pin type with any of the C-shaped buckles; wherein the moving part is selected by a combination wrench or fixed Any of the wrenches is presented; wherein the actuation system of the actuator is selected by any of a ratchet wrench or a general wrench having a changeable direction.

The main purpose of this creation is to provide a situation in which the internal mechanism of the torque wrench is prevented from being broken due to dropping or improper operation.

The function of the torque wrench anti-off mechanism of the present invention is that the creation system comprises: a grip, which has a tubular hollow shape as a whole, and a grip region is defined at the outer edge of the grip, and the inside defines a capacity. a space is provided, and a resisting bolt is arranged at the bottom of the receiving space; a set of adjusting members disposed at the resisting bolt; a joint portion is disposed at the receiving space of the grip; and an actuating portion has a guiding rod is disposed at the receiving space of the grip and is in a pivotal state with the joint portion; and a pulling body is disposed at the upper end of the guiding rod; wherein the joint portion has a a resisting member is disposed at an upper end of the resisting bolt of the gripping space of the grip and is in a state of resisting the adjusting member of the receiving space of the grip, and the resisting member has a positioning area at the upper end thereof; The detachment member has a through hole penetrating the upper and lower sides; a detaching member is disposed at a positioning area of the abutting member of the joint portion, and is set Provided at a perforation of the joint of the joint portion, and the jumper is small overall The perforation of the retaining member presenting a reserved space; and an actuator member, based group provided at the lower end of the guide rod of the actuation portion, the system having a location area, And the boycott is in a state of resistance. Therefore, when the creation is inadvertently slipped or improperly operated during use, the tripping member of the joint portion is disengaged from the resisting member and the actuating member of the joint portion, and the retaining portion of the joint portion is removed. The tripping member is restricted to the perforation reserved space inside the retaining member of the joint portion, and the internal mechanism of the torque wrench is prevented from losing its utility.
