Specific implementation mode

[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1, as Figures 1-4 shown, the present invention provides a single-sector torque calibration lever, including a single-sector lever 1. A connecting square head 2 is arranged on the outer surface wall of the single-sector lever 1. A placing groove 4 is opened on the outer surface wall of the single-sector lever 1. A connecting block 5 is fixedly installed on the inner wall of the placing groove 4. A steel belt 6 is fixedly installed on the outer surface wall of the connecting block 5. One end of the outer wall of the steel belt 6 is fixedly installed with a connecting screw sleeve 7. A placing mechanism 8 is arranged inside the connecting screw sleeve 7.

[0023] The overall effect achieved by the entire Embodiment 1 is that the connecting screw sleeve 7 can quickly connect the placing mechanism 8 and the steel belt 6, improving the stability of the placing mechanism 8 and preventing the placing mechanism 8 from falling off the steel belt 6. Then, the piece to be calibrated, verified or calibrated is connected through the connecting square head 2. The placing mechanism 8 can place the force value weight 804 and can fix the force value weight 804 at the same time, preventing the force value weight 804 from falling off and affecting the calibration.

[0024] Embodiment 2, as Figures 1-4As shown in the figure, the placement mechanism 8 includes a connecting rod 801. At the top end of the connecting rod 801, a connecting screw 808 is fixedly installed. At the bottom end of the connecting rod 801, a tray 803 is fixedly installed. On the surface of the tray 803, a force value weight 804 is arranged. A thread groove 802 is formed on the outer wall of the connecting rod 801, and a thread sleeve 805 is threadedly connected to the inner wall of the thread groove 802. At the bottom end of the thread sleeve 805, a pressing plate 806 is fixedly installed. On the outer wall of the thread sleeve 805, two rotating rods 807 are fixedly installed. A balance rod 9 is fixedly installed on the outer wall of the single-sector lever 1. At one end of the outer wall of the balance rod 9, a balance weight 10 is threadedly connected. A circular groove 3 is formed on the outer wall of the single-sector lever 1, and the connecting screw 808 is threadedly connected to the thread groove 802.

[0025] The overall effect of the entire Embodiment 2 is that in order to prevent the force value weight 804 from falling off the tray 803, the rotating rod 807 can be rotated. The rotating rod 807 drives the thread sleeve 805 to rotate in the thread groove 802 on the connecting rod 801. During the rotation of the thread sleeve 805, the pressing plate 806 is driven to move downward until the pressing plate 806 contacts the force value weight 804, applying a certain pressure to the force value weight 804 to fix the force value weight 804 on the tray 803, thereby reducing the probability of the force value weight 804 falling on the tray 803.

[0026] Working principle: A circular groove 3 is formed on the single-sector lever 1, which can reduce the weight of the single-sector lever 1. The balance weight 10 is threadedly connected to one end of the outer wall of the balance rod 9. Through the connecting screw 808 and the connecting nut 7, the placement mechanism 8 and the steel belt 6 can be quickly threadedly connected, improving the stability of the placement mechanism 8 and preventing the placement mechanism 8 from falling off the steel belt 6. Then, the piece to be calibrated, verified or calibrated is connected through the connecting square head 2. After the device is connected, it is adjusted to balance through the connecting square head 2 and the balance weight 10. According to the magnitude of the torque value to be calibrated, verified or calibrated, the force value weights 804 are added in sequence. Then, the standard torque value is calculated based on the weight of the added force value weights 804 and the effective force arm length of the single-sector lever 1. At this time, the torque value to be measured is compared with the standard torque value. At the same time, in order to prevent the force value weight 804 from falling off the tray 803, the rotating rod 807 can be rotated. The rotating rod 807 drives the thread sleeve 805 to rotate in the thread groove 802 on the connecting rod 801. During the rotation of the thread sleeve 805, the pressing plate 806 is driven to move downward until the pressing plate 806 contacts the force value weight 804, applying a certain pressure to the force value weight 804 to fix the force value weight 804 on the tray 803, thereby reducing the probability of the force value weight 804 falling on the tray 803.

[0027] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the relevant art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still fall within the protection scope of the technical solution of the present utility model.
