Description

Technical Field

[0001] The utility model relates to the technical field of torque wrenches. More specifically, the utility model relates to a digital display torque wrench with a self - contained scanning and recognition function. Background Art

[0002] Torque wrenches are generally divided into two categories: electric torque wrenches and manual torque wrenches. When tightening threaded fasteners such as screws, bolts, and nuts, it is necessary to control the applied torque to ensure that the thread is tightened and not damaged due to excessive torque. Therefore, a torque wrench is usually required for operation. When the existing digital display torque wrench is in use, the upper limit of the torque value is set according to the force value information of the fastener. When the torque value applied by the wrench reaches the set value, it means that the force application operation needs to be stopped. However, due to the lack of protective functional components, the digital display device on the wrench is still exposed when not in use, resulting in easy damage to the digital display device due to external force collision and pressure during the carrying process of the wrench, affecting the normal service life of the digital display torque wrench. Based on this, the utility model designs a digital display torque wrench with a self - contained scanning and recognition function to solve the above problems. Summary of the Utility Model

A silica gel cushion block 601 is fixedly installed on the cover 6. When being externally bumped during the carrying process, the cover 6 and the silica gel cushion block 601 can produce a buffering and compressive protection effect on the digital display device 5. Two insertion blocks 602 are symmetrically and fixedly installed on the cover 6 outside the silica gel cushion block 601. A positive magnetic sheet 603 is fixedly installed on the end face of the insertion block 602. Limit grooves 9 adapted to the insertion blocks 602 are opened in both the upper notch 7 and the lower notch 8, so that the insertion blocks 602 can be inserted into the limit grooves 9. A negative magnetic sheet 901 is fixedly installed in the limit grooves 9. By the mutual contact and adsorption of the positive magnetic sheet 603 and the negative magnetic sheet 901, the cover 6 can be positioned on the upper notch 7 or the lower notch 8.

[0023] Among them, as Figure 3 and Figure 4 shown, a lifting convex block 604 is fixedly connected to the side of the cover 6. Avoidance openings 701 are opened on the sides of both the upper notch 7 and the lower notch 8. The lifting convex block 604 is adapted to the avoidance openings 701, so that the avoidance openings 701 can effectively avoid the lifting convex block 604.

[0028] The working principle of the present utility model:

[0029] During use, the lifting lug 604 is used to pull out the cover 6 on the upper slot 7, and then the insertion block 602 is inserted into the limit groove 9 on the lower slot 8. By using the mutual contact and adsorption of the positive magnetic sheet 603 and the negative magnetic sheet 901, the cover 6 can be positioned on the lower slot 8, so as to facilitate the storage and placement of the cover 6. The torque value is set on the control panel 502 according to the force value information of the fastener. By rotating the fastener with the wrench head 2, the torque sensor 3 can monitor the applied torque value in real time, and the digital display screen 501 digitally displays the applied torque value until the applied torque value reaches the set value, and then the force application operation can be stopped. After use, the lifting lug 604 is used to pull out the cover 6 on the lower slot 8, and then the insertion block 602 is inserted into the limit groove 9 on the upper slot 7, so that the cover 6 effectively seals the upper slot 7. By using the mutual contact and adsorption of the positive magnetic sheet 603 and the negative magnetic sheet 901, the cover 6 is positioned on the upper slot 7. When being bumped by an external force during the carrying process, the cover 6 and the silica gel pad 601 can produce a buffer and anti-compression protection effect on the digital display device 5, thereby preventing the digital display device 5 from being easily damaged by an external force during the carrying process of the wrench.
