Description

Technical Field

[0001] The utility model relates to the field of tension sensors, in particular to a tension sensor with a protective device. Background Art

[0002] A force sensor is a device used to measure the pulling force or tension applied to an object. They are widely used in industries such as industry, construction, aerospace, and automotive. Force sensors are typically based on strain gauge technology, which measures the tiny deformation of a material under load to calculate the applied force.

[0003] The plate-ring type tension sensors in existing tension sensors may be exposed to harsh environments during use, and may fall, which may cause damage to these components. Since the plate-ring type tension sensors do not have a protective structure, they may cause wear or failure, thereby affecting their function and accuracy, and greatly reducing the service life of the plate-ring type tension sensors.

A protrusion 7 is fixedly connected to one side of the sealing plate 4, and one end of the protrusion 7 is tightly fitted with one side of the protective cover 8.

[0025] After the sensor body 1 is placed inside the shell 2, the sealing plate 4 is fixedly placed at the opening of the shell 2, and the opening of the shell 2 is closed to prevent the sensor body 1 from falling out of the shell 2. At the same time, the first buffer pad 3 and the second buffer pad 5 are fitted together with the outer surface of the sensor body 1. When a fall occurs, the first buffer pad 3 and the second buffer pad 5 can prevent the sensor body 1 from colliding with the shell 2, and can also buffer the impact force generated during the fall, preventing the sensor body 1 from being subjected to a large impact force. At the same time, a protective cover 8 is provided at the connection port to protect it, avoiding bending of the connection end. At the same time, the groove 6 makes it easy to put the shell 2 on the sensor body 1, and the protrusion 7 closes the groove 6, greatly increasing the protective effect of the pulling device, thereby adding a certain protective structure to the device, avoiding damage due to falling, and preventing it from wearing or malfunctioning, so that its function and accuracy are not affected, thereby greatly improving the service life of the plate ring type tension sensor.

[0026] In this embodiment, a positioning assembly is provided on one side of the sealing plate 4, and the positioning assembly is used to fix the position of the sealing plate 4 on the outer shell 2. The positioning assembly includes an installation cavity 9 opened on both sides of the sealing plate 4, and the installation cavity 9 is fixedly connected to a spring 10. One end of the spring 10 is fixedly connected to a positioning rod 11. A positioning hole 12 is opened on the outer shell 2, and one end of the positioning rod 11 extends into the positioning hole 12.

[0027] When the sealing plate 4 is placed at the opening of the housing 2, the spring 10 in the mounting cavity 9 pushes one end of the positioning rod 11 into the positioning hole 12, thereby preliminarily fixing the sealing plate 4 on the housing 2 and closing the opening of the housing 2 to prevent the sensor body 1 from falling out of the housing 2.

[0036] It should be noted that the utility model is a tension sensor with a protective device. After the sensor body 1 is placed inside the shell 2, the sealing plate 4 is fixedly placed at the opening of the shell 2, and the opening of the shell 2 is closed to prevent the sensor body 1 from falling from the shell 2. At the same time, the first buffer pad 3 and the second buffer pad 5 are fitted together with the outer surface of the sensor body 1. When a fall occurs, the first buffer pad 3 and the second buffer pad 5 can prevent the sensor body 1 from colliding with the shell 2, and can also buffer the impact force generated during the fall, preventing the sensor body 1 from being subjected to a large impact force. At the same time, a protective cover 8 is provided at the connection port to protect it, preventing the connection end from bending.
