Description

Torque wrench with torque value

This creation relates to a "torque wrench with a torque value for display", especially for a torque wrench. When the torque adjustment mechanism is adjusted, the change of the torque is transmitted to the display numerical device, and the value of the torque value is displayed.

Press, the torque wrench can adjust and set the torque value. When the torque value is exceeded, it will make a sound, or generate a idling, so that the user can clearly know that the preset torque value has been exceeded, and no longer apply force. The utility model can relatively protect the locking component and the torque wrench from being damaged by the force applied, and can surely tighten the locking component. In general, most of the torque wrenches are driven by a rotating control member to rotate the screw provided inside the outer handle, and then axially displaced by the slider screwed with the screw in the outer handle when the slider is in different positions. That is, the spring can be subjected to different degrees of compression, thereby achieving the effect of adjusting the value of the torque. However, there are two ways for the conventional torque wrench to display the magnitude of the torque: (1) The numerical scale of the torque value is indicated on the grip of the torque wrench, and the disadvantage is that the outer circumference of the grip is not large, only It can mark some linear scales and large torque values along the outer circumference, so that the torque value display is not accurate and rough; (2) The conventional torque wrench has a digital electronic torque display device, although its torque value The display is precise enough, but the disadvantage is that the operator will inadvertently discard after using the conventional torque wrench. Since the torque display device is made of electronic parts and is more precise, it often suffers from falling or vibrating. Large and prone to damage, and often used for a long time, often need to replace the battery, otherwise the torque value can not be displayed and can not be used.

Therefore, in the current business competition, how to combine the torque display function and device that is both precise and difficult to damage, and to develop and improve the above-mentioned common shortcomings, it is the goal of the relevant industry to develop and research. In view of this, the creator has developed and designed the idea of thinking and creation, and has developed and designed it through many years of research and trials, and many revisions and improvements.

How to develop a torsion display function and device that is both precise and difficult to damage, can accurately display the change of the torque value of the torque wrench, and can resist falling and not easily damaged, and can not affect the normal use of the torque wrench. It is the problem that the creator wants to improve.

The purpose of the present invention is to provide a torque wrench with a display torque value, which comprises: a torque wrench having a hollow outer handle, one end of the outer handle is inserted into a tool head body, and the other end is provided with a torque The adjusting mechanism is inserted forward and connected to the tool head body, and the other end of the torque adjusting mechanism is combined with a control component; a display numerical device is disposed on the torque wrench and connected to the control component The display value device includes a housing and a plurality of digital wheels, a spindle and a plurality of transmission gears disposed in the housing, wherein the spindle extends through the plurality of transmission gears, and the plurality of transmission gears are rotatably located One or more of the plurality of digital wheels are adjacent to each other and are respectively engaged with the plurality of digital wheels, and the plurality of digital wheels are sequentially driven into position by the plurality of transmission gears.

The effect of this creation is that (1) the internal parts of the display numerical device are mechanical parts, and the plurality of digital wheels are sequentially driven to carry the position, and the numerical value of the adjusted torque value is displayed in a precise digital manner; Since the internal parts of the numerical device are mechanically typed parts, they are more resistant to falling and shocking, and are not easily damaged, and have no trouble of replacing the battery for a long time.
