[0002] The sensor turntable bearing seat is a large and extra-large bearing seat with a special structure that can accept comprehensive loads. It has the characteristics of compact structure, sensitive rotation, and easy installation and maintenance. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is what is often called the bearing seat. Installing a bearing seat weight sensor on the bearing seat can generally detect the bearing capacity of the bearing seat to avoid damage to the bearing seat due to excessive bearing force.

[0003] The connector on the tension sensor is usually installed by multiple screws, which is troublesome to install in the holes, resulting in low assembly efficiency of the tension sensor. Therefore, we designed a seat-type sensor, in which the terminal head is installed in a tensioning manner, which is simple and quick to install and improves the assembly efficiency of the sensor.

[0011] 1. The beneficial effects of the utility model are as follows: the utility model covers the surface of the connector body with a rubber pad, then inserts the bottom of the connector body into the top of the sensor body, and then operates the threaded column to rotate. Due to the thread, the wedge-shaped stopper moves toward the inner cavity of the rectangular cavity. The inclined surface of the wedge-shaped stopper contacts the inner wall of the rectangular cavity, causing the connector body to move downward, thereby achieving tensioning fixation. No alignment holes are required for installation, and the terminal head can be installed in a tensioning manner. The installation is simple and quick, thereby improving the efficiency of sensor assembly.

[0012] 2. The utility model can limit the wedge-shaped stop block by setting the wedge-shaped stop block to fit with the inner wall of the installation cavity, preventing the wedge-shaped stop block from rotating due to the rotation of the threaded column, thereby improving the stability of the movement of the wedge-shaped stop block.

[0013] 3. The utility model uses a rubber pad and a rubber sleeve cover in combination. When the joint body moves downward, the rubber pad will be squeezed and deformed, providing a buffer when the joint body is tensioned downward, ensuring that the joint body will not break when moving downward. The rubber sleeve cover can cover the joint body when it is not in use and protect the inside of the joint body.

[0014] 4. The utility model provides a plastic buckle. After the bearing is installed in the inner cavity of the built-in ring, the plastic buckle is inserted into the inner cavity of the annular groove, which can limit the bearing and prevent the bearing from being separated from the inner cavity of the built-in ring.

The top of the wedge-shaped stop block 74 fits with the inner wall of the installation cavity 4. The wedge-shaped stop block 74 can be limited by the arrangement of the wedge-shaped stop block 74 fitting with the inner wall of the installation cavity 4 to prevent the wedge-shaped stop block 74 from rotating due to the rotation of the threaded column 73, thereby improving the stability of the movement of the wedge-shaped stop block 74.
