Description

The present invention relates to torque structures.

Conventional torque structures (eg, "Wrench Torque Measuring Mechanism" of US Pat. Nos. 5,300,000 and 5,000,000) include a wrench. The wrench includes a head, a gripping handle, a tube member, a torque adjuster, and a torque measuring mechanism. The tube member has an elongated hole formed in the tube body, a handle connected to one end, and a head connected to the other end via a torque output structure. The torque adjustment device includes an adjustment knob attached to the handle and a pin mounted between the tube member and the handle and movable within the elongated bore in response to rotation of the adjustment knob. A torque measuring mechanism is attached to the wrench and includes a surveying sleeve, a retaining ring and a collar. The surveying sleeve includes a helical track that is fitted to the outside of the pipe member and recessed into the inner wall of the surveying sleeve so that the track wall surface is in contact with the pin, and a plurality of scales displayed on the outer surface of the surveying sleeve. . A locking ring is attached to the tube member and in combination with the handle restricts the survey sleeve from rotating outside the tube member and from being displaced in the longitudinal direction of the tube. A collar is positionally constrained on the outside of the survey sleeve and has a window facing the scale.

However, the conventional wrench torque measuring mechanism has the following drawbacks (1) to (3).
(1) As shown in FIG. 1 of Patent Document 2, the torque can be adjusted by rotating the adjustment knob due to its structure. Since it is turned by pinching, it is not easy to apply force to adjust the torque with the adjustment knob. Especially when the torque is large, the pressure received by the elastic member increases, and the force to rotate the adjustment knob must be increased. Instead, it became more difficult to turn the adjustment knob.
(2) The adjustment knob is located at the extreme end, structurally, the micro window is located near the end, and the scale is located in the middle. A handle separates the microwindow and the scale. The handle has a constant length. The magnitude of the torque had to be viewed at the same time through the micro-window and the scale, which was not easy to see at the same time because the micro-window and the scale were at different locations apart from each other. Such separate locations of the microwindow and the scale were not ergonomically favorable.
(3) As shown in FIG. 2 of Patent Document 2, the spiral track is provided on the inner peripheral surface of the surveying sleeve, and the structure of the spiral track could not be manufactured by injection molding. In addition, when the spiral track is manufactured by a machine tool such as a lathe or a milling machine, it is not easy to machine the spiral track. , there was an error between the distance the pin traveled and the distance the ring made one revolution.
