[0002] A tension sensor is a device used to measure and monitor tension (the magnitude of force). Tension sensors are usually designed to measure tensile force, that is, the force in one direction, but some designs can also be used to measure compressive force or torque. Tension sensors can be applied in various occasions, including industrial production, scientific research, medical monitoring and other fields. According to specific application scenarios and requirements, tension sensors can have different designs and structures. For example, some tension sensors are designed to be miniaturized for easy integration into portable devices, while some are designed to be highly accurate and suitable for scientific research and high-end engineering systems.
[0003] Existing tension sensors are widely used, but existing tension sensors are usually designed to measure tensile force, that is, the force in one direction, and cannot measure the tension of a rope during movement. Moreover, existing tension sensors have no protection measures and cannot protect the components inside the tension sensor. Therefore, a parallel beam roller type tension sensor is proposed for the above problems. Content of the Utility Model
[0004] The purpose of the utility model is to provide a parallel beam roller type tension sensor to solve the problems that existing tension sensors cannot measure the tension of a rope during movement and existing tension sensors have no protection measures in the above background technique.

[0006] A parallel beam roller type tension sensor includes symmetrically arranged outer shells. At the bottom end inside the outer shell, a vertically arranged displacement sensor is fixedly connected. One side of the displacement sensor is fixedly connected with a wire. A return spring is arranged outside the input rod of the displacement sensor. The top end of the input rod of the displacement sensor is fixedly connected with a connecting plate. One end of the connecting plate is fixedly connected with a first bearing. The side of the first bearing away from the connecting plate is fixedly connected with a tension roller. A limiting component is arranged on one side of the tension roller. Parallel beams fixedly connected with the upper and lower ends of the outer shell are symmetrically arranged at the upper and lower ends of the outer shell.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] 1. In the present utility model, by arranging the housing, displacement sensor, wire, return spring, connecting plate, first bearing and tension roller, the tension when the rope moves can be measured. When measurement is required, the rope is placed on the outer side of the tension roller. When the moving rope is stressed, the tension roller inside the bearing rotates and descends, and the displacement sensor converts the displacement amount of the tension roller into a physical quantity of force. After the measurement is completed, the rope is taken out, and the return spring resets to drive the tension roller to reset, and thus the measurement of the rope tension can be completed.

First, the limiting assembly is installed. The threaded cylinder is placed above the circular hole and the first bolt is screwed into the inner side of the threaded cylinder, and thus the installation of the limiting assembly can be completed. When the rope moves, the limiting wheel inside the second bearing rotates in the wheel groove following the tension roller, thereby preventing the rope from detaching from the device and causing the measurement to fail.
[0014] 3. In the present utility model, by arranging the parallel beam, engaging groove, through hole, engaging block, threaded groove, second bolt and protection plate, the components inside the device can be protected. After the device is used up, the engaging block on the protection plate is inserted into the inner side of the engaging groove, and the second bolt is inserted into the inner side of the through hole and screwed into the inner side of the threaded groove, and thus the installation of the protection plate can be completed, and the protection plate can protect the components inside the device.

[0025] The wire 3 penetrates through the outer shell 1 and is fixedly connected to the outer shell 1. The bottom end of the return spring 4 is fixedly connected to the top end of the displacement sensor 2, and the top end of the return spring 4 is fixedly connected to the bottom end of the connecting plate 5. The return spring 4 can drive the tension roller 7 to reset after the measurement. Symmetrically arranged engaging grooves 10 are formed on the front and rear sides of the parallel beam 9. A through hole 11 is formed on the side of the parallel beam 9 away from the outer shell 1. An engaging block 12 is engaged and connected inside the engaging groove 10. A threaded groove 13 is formed inside the engaging block 12. A second bolt 14 screwed with the threaded groove 13 is arranged inside the through hole 11. On the side of the engaging block 12 away from the parallel beam 9, a protective plate 15 is fixedly connected. The protective plate 15 can protect the components inside the device. The limiting component 8 includes symmetrically arranged wheel grooves 801 formed on the outer side of the tension roller 7. A circular hole 802 penetrating the connecting plate 5 from top to bottom is formed inside the connecting plate 5. Above the circular hole 802, a threaded cylinder 803 is provided. A first bolt 804 screwed with the threaded cylinder 803 is arranged inside the circular hole 802. At the top end of the threaded cylinder 803, a connecting frame 805 is fixedly connected. At both ends of the connecting frame 805 away from the threaded cylinder 803, symmetrically arranged second bearings 806 fixedly connected to the connecting frame 805 are provided. On the side of the second bearing 806 away from the connecting frame 805, a limiting wheel 807 is fixedly connected. A horizontally arranged connecting rod 808 is fixedly connected between the two limiting wheels 807. The limiting component 8 can prevent the rope from disengaging from the device and causing measurement failure.
