It is used to measure and correct the torque and torque settings of various electric screwdrivers, pneumatic screwdrivers, torque screwdrivers, and torque wrenches. It is suitable for various products such as shafts, bearings, and bottle caps that require torque measurement and comes with specialized clamps and fixtures.

[0003] Utility model CN216621597U discloses a calibration device for a torque tester, comprising a supporting base plate, a supporting frame, a lifting device, a clamping device, a fixed base, and a tester fixing device. The supporting frame is mounted on the supporting base plate, the lifting device is mounted on the supporting frame and on the supporting base plate, the clamping device is mounted on the lifting device, the fixed base is mounted on the supporting base plate, and the tester fixing device is mounted on the fixed base. The lifting device includes a guide rod, a slider, a connecting rod, a pressure sensor, a hydraulic cylinder, and ball bearings. The clamping device includes a supporting block, a clamping handle, a spiral guide disc, a partition, a guide groove, a connecting rod, and a clamping rod. The tester fixing device includes a sliding groove, a fixing screw, a slider, a fixing handle, and a fixing block. This utility model belongs to the technical field of torque tester calibration devices, specifically a simple and practical calibration device for a torque tester that is adjustable to adapt to different torque meters.

[0004] Existing torque tester calibration devices only have a calibration function. If a calibration device fails the test and cannot be powered on, it is not possible to quickly troubleshoot whether the problem exists. This results in the problem of calibrating first instead of powering on for testing. Therefore, those skilled in the art have provided a torque tester calibration device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a calibration device for a torque tester to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a calibration device for a torque tester, comprising an insulating base, two legs symmetrically fixedly connected to the bottom of the insulating base, a calibration device body disposed on the top of the insulating base, a plurality of control buttons disposed on the top of the calibration device body, two detection heads electrically connected to one side of the calibration device body, a first conductive block and a second conductive block symmetrically disposed on the top of the insulating base, an indicator light fixedly connected to the top of the insulating base, the second conductive block and the indicator light being electrically connected, a battery fixedly connected to the bottom of the insulating base, the battery being electrically connected to the first conductive block, a charging interface provided on one side of the battery, and a switch disposed on the bottom of the battery.

[0007] As a further embodiment of this utility model: the top of the insulating base has two rectangular holes symmetrically opened, and a clamping block is slidably connected through each of the two rectangular holes; the bottom of the insulating base has two connecting plates symmetrically fixedly connected, and a tension spring is fixedly connected between each of the two connecting plates and the two clamping blocks.

[0008] As a further improvement of this utility model: multiple anti-slip protrusions are fixedly connected to the opposite sides of the two clamping blocks, and handles are fixedly connected to the opposite sides of the two clamping blocks.

[0009] As a further embodiment of this utility model: one of the legs has a through hole on one side, and the battery is located between the two legs.

[0010] As a further improvement of this invention: the calibration device body is electrically connected to the battery, and the indicator light is located on one side of the second conductive block.

[0011] As a further embodiment of this utility model: an insulating plate is fixedly connected to the top of the insulating base, and the insulating plate is located between the first conductive block and the second conductive block.

[0012] As a further improvement of this utility model: the clamping block is T-shaped, and the bottom sides of the clamping block are attached to the top of the insulating base.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The torque tester can be placed on an insulating board. When the torque tester is placed on the insulating board, the two clamping blocks are squeezed apart to the sides. The two clamping blocks are pulled closer together by the tension of two tension springs, thus keeping them in a state of constant contact with both sides of the torque tester. If power-on testing is required, the wire to be tested inside the torque tester can be pulled out. At this time, the two wires need to be in contact with the first conductive block and the second conductive block respectively. Then, press the switch to start the battery to power the first conductive block. The current in the first conductive block will be conducted to the torque tester through the wire. At the same time, the current in the other wire will also be conducted through the second conductive block. The current in the second conductive block will power the indicator light and light it up, thus determining whether the torque tester can be powered.

[0015] This utility model is simple to use. Two wires can be pulled out from the torque tester to contact the first conductive block and the second conductive block respectively for power-on detection. The contacts of the two detection heads can contact the detection port of the torque tester for calibration. The two clamping blocks can clamp and fix the torque tester by bringing the two clamping blocks close to each other through two tension springs. Attached Figure Description

[0022] Please see Figures 1-4In this embodiment of the present invention, a calibration device for a torque tester includes an insulating base 1. Two support legs 2 are symmetrically fixedly connected to the bottom of the insulating base 1. A calibration device body 15 is provided on the top of the insulating base 1. Multiple control buttons 14 are provided on the top of the calibration device body 15. Two detection heads 13 are electrically connected to one side of the calibration device body 15. A first conductive block 3 and a second conductive block 9 are symmetrically arranged on the top of the insulating base 1. An indicator light 7 is fixedly connected to the top of the insulating base 1. The second conductive block 9 and the indicator light 7 are electrically connected. A storage battery 16 is fixedly connected to the bottom of the insulating base 1. The storage battery 16 is electrically connected to the first conductive block 3. A charging interface 12 is provided on one side of the storage battery 16. A switch 4 is provided at the bottom of the storage battery 16.

[0023] In this embodiment, two rectangular holes 6 are symmetrically opened on the top of the insulating base 1, and clamping blocks 8 are slidably connected through each of the two rectangular holes 6. Two connecting plates 18 are symmetrically fixedly connected to the bottom of the insulating base 1, and tension springs 17 are fixedly connected between the two connecting plates 18 and the two clamping blocks 8. The torque tester can be placed on the insulating plate 10. When the torque tester is placed on the insulating plate 10, it will press the two clamping blocks 8 to the sides to move away from each other. The two clamping blocks 8 will move closer to each other through the tension of the two tension springs 17, so as to keep them always in contact with the sides of the torque tester for clamping.

[0024] In this embodiment, multiple anti-slip protrusions 11 are fixedly connected to the opposite side of the two clamping blocks 8, and handles are fixedly connected to the opposite side of the two clamping blocks 8.

[0025] In this embodiment, a through hole 5 is provided on one side of one of the support legs 2, and the battery 16 is located between the two support legs 2.

[0026] In this embodiment, the calibration device body 15 and the storage battery 16 are electrically connected. The indicator light 7 is located on one side of the second conductive block 9. When power is required for testing, the wire to be tested in the torque tester can be pulled out. At this time, two wires need to be in contact with the first conductive block 3 and the second conductive block 9 respectively. Then, the switch 4 is pressed to start the storage battery 16 to supply power to the first conductive block 3. The current in the first conductive block 3 will be conducted to the torque tester through the wire. At this time, the wire on the other side will also be conducted with current through the second conductive block 9. The current in the second conductive block 9 will supply power to the indicator light 7 and light it up.

[0027] In this embodiment, an insulating plate 10 is fixedly connected to the top of the insulating base 1, and the insulating plate 10 is located between the first conductive block 3 and the second conductive block 9.

[0028] In this embodiment, the clamping block 8 is T-shaped, and the bottom sides of the clamping block 8 are attached to the top of the insulating base 1.

[0029] The working principle of this utility model is as follows: The torque tester can be placed on the insulating plate 10. When the torque tester is placed on the insulating plate 10, it will press the two clamping blocks 8 to the sides to move away from each other. The two clamping blocks 8 will move closer to each other through the tension of the two tension springs 17, thus maintaining a state of clamping against both sides of the torque tester. If power-on testing is required, the wire to be tested inside the torque tester can be pulled out. At this time, the two wires need to contact the first conductive block 3 and the second conductive block 9 respectively. Then, the switch 4 is pressed to start the battery 16 to supply power to the first conductive block 3. The current in block 3 will be conducted to the torque tester through the wire. At the same time, the current in the other wire will also be conducted through the second conductive block 9. The current in the second conductive block 9 will power the indicator light 7 and light it up, thereby determining whether the torque tester can be powered on. The insulating plate 10 is used to support the torque tester to prevent current conduction. The two detection heads 13 on the calibration device body 15 on one side can contact the detection port of the torque tester to perform calibration work. The battery 16 can also power the calibration device body 15. The through hole 5 can be used to run the wire and connect to the first conductive block 3.
