Digital torque wrench with lighting device

The present invention relates to a digital torque wrench with a lighting device, in particular, a torque wrench with a multi-color lighting device at the near working end to achieve illumination and multi-color torque warning applications.

Press, the wrench tool uses the principle of lever to pull the screw-solid workpiece to achieve the effect of tightening or loosening. It is necessary to assemble and combine the components of various industries by the screw firmware. The general industrial products need to use each due to structural differences. Screws are assembled and fixed with different torsion forces, such as heavy industry such as aviation, shipbuilding and cars. Their components can be assembled with considerable strength to achieve a solid structure, withstand the impact of air pressure and power, while precision industries such as In electronic machinery, its components cannot be assembled with excessive torque to ensure its precise operation. However, no matter what kind of industrial products, less than one point of torque or more than one point of torque when combined with a screw is likely to cause a structure. The screw is ineffective or damaged, and the wrench tool is the key to controlling the torque.

Please refer to the "Digital Torque Wrench" patent of the Republic of China Patent Application No. 096200361, which is a conventional digital torque wrench comprising a tool head having a head with a screw-locking element at one end and the other end. Having a joint section, the side of the joint section is flat and a bridge strain gauge is arranged, and the outer side of the joint section is provided with a pipe body, and the pipe body forms an opening in the outer side wall of the pipe through the inner space of the pipe; To display numerical data; a digital control device, The signal detected by the bridge strain gauge is received, and the data is transmitted to the display for display.

The above-mentioned creation is a digital digital torque wrench that senses the torque value through the degree of deformation generated by the bridge strain gauge during the operation of the torque wrench, and then the actual torque value generated during the turning operation is Digital display; however, the digital torque wrench used does not have a lighting device and a light prompting system. When the operator is working in a dimly lit workplace, it is quite inconvenient to operate the lighting device separately; in addition, the conventional digital torque wrench only provides the torque value. The display does not actively alert the torque value to the desired value.

In view of this, the creator has been engaged in the development of related industries for many years, and has in-depth discussions on the problems faced by the existing digital torque wrenches, and actively seeks solutions. After long-term research and development, he has finally succeeded in creating The utility model relates to a digital torque wrench with a lighting device, which is a torque wrench with multi-color lighting device near the working end, so as to achieve illumination and multi-color torque warning application.

The present invention relates to a digital torque wrench with a lighting device, which is a torque wrench with a multi-color lighting device at the near working end to achieve illumination and multi-color torque warning applications.

In order to achieve the foregoing creative purpose, the digital torque wrench with the illumination device comprises a main body working rod member and a grip rod member, the main working rod member has a wrench head at one end and the other end portion is assembled with the grip rod member. a shaft section, the rod body is provided with at least one strain gauge on the side, the handle rod member has an inner space for inserting the shaft body portion, and a display screen is disposed on one side of the handle rod member And the digital unit of the operation interface, the strain gauge and the digital order The electrical connection is provided on the other side of the handle member, and the illumination device is electrically connected to the digital unit, and the digital unit is provided with a lighting control module with simple illumination control. And a warning control module for detecting the color of the illumination by detecting the torque value; thus, the illumination unit can be activated separately through the digital unit, and the illumination device can be switched through the warning control module to make different torque values measured according to the strain gauge. As a multi-color warning.

The handle member is provided with a rear plug member at the rear end, and the rear plug member has an inner tube which is inserted into the inner space and presents the loop sleeve portion.

The illuminating device is disposed at an end of the grip bar member near the wrench head, and the illuminating device has a lighting direction that is correct for the working direction of the wrench head.

It can be seen from the above-mentioned creations that the "digital torque wrench with lighting device" has a lighting device, which can facilitate the operator to make up the insufficient light through the lighting device when working in a dim workplace, so as to facilitate the operation. The lighting device can also be synchronized with the measured torque data to prompt the operator to apply the torque value of the operation in a changing color or flashing manner. Therefore, the novel can be said to be a practical and progressive creation. It is worthy of promotion by the industry and publicity to the public.

This creation is about a digital torque wrench with a lighting device, which is a torque wrench with multi-color lighting device at the near working end to achieve illumination and multi-color torque warning applications. Please refer to the first to fourth figures. As shown, the present invention "digital torque wrench with illumination device" includes a main body working rod member 1 and a grip rod member 2; the main working rod member 1 has a wrench head 11 at one end and a grip member at the other end. 2 sets of the shaft portion 12, the shaft portion 12 is provided with at least one strain gauge 13 on the side, the handle rod member 2 has an inner space 21 for inserting the shaft portion 12 into the assembled body, and the handle portion A digital unit 22 having a display screen and an operation interface is disposed on one side of the rod member 2, and the strain gauge 13 is electrically connected to the digital unit 22, and the other side of the handle member 2 is provided with a multi-color lighting effect. The illuminating device 3 is electrically connected to the digital unit 22, wherein the digital unit 22 has a lighting control module with simple illumination control, and an alarm control module for detecting the color of the illumination by detecting the torque value; Single through the digital unit 22 The lighting device 3 is activated, and the lighting device 3 can also be switched through the warning control module to make the multi-color warning according to the different torque values measured by the strain gauge 13, for example, the lighting device 3 is not reached when the preset torque value is reached.
