Description

Technical Field

[0001] The utility model relates to the technical field of cable-pulling sensors, and more specifically, to a cable-pulling sensor structure with adjustable installation position. Background Art

[0002] A cable-pulling sensor, also known as a cable-pulling displacement sensor, is a sensor used to precisely measure the tension control device of an object. It determines the magnitude of the force exerted on the object by fixing and connecting the cable on the object to the sensor and measuring the expansion and contraction of the cable. The working principle of this sensor is based on a retractable spring or elastic material, which includes a rope connected to the object to be measured. When the object to be measured is subjected to an external force, the rope generates tension and transmits this tension to the spring or elastic material. By measuring the degree of deformation of the spring or material, the magnitude of the external force applied to the object to be measured can be known;

One technical effect of the present invention is that it has a reasonable design, a wide application range, is very convenient to use, and moreover, has a small volume and low cost. The inventor found the following problems in the process of implementing the present utility model:

[0004] During the use of the existing cable-pulling sensor assembly, when installing the cable-pulling sensor, due to the complex environment of its installation position, the assembly process of the cable-pulling sensor is often cumbersome, resulting in difficult installation of the cable-pulling sensor. At the same time, when using the cable-pulling sensor, the wire pulled out by the cable head often deflects, resulting in wear between the wire and the wire outlet area, and thus damage to the wire;

[0005] Therefore, a cable-pulling sensor structure with adjustable installation position is proposed for the above problems. Summary of the Utility Model

[0006] In order to overcome the above-mentioned defects of the prior art, the present utility model provides a rope-pulling type sensor structure with adjustable installation position to solve the problems raised in the above-mentioned background art.

[0007] To achieve the above object, the present utility model provides the following technical solution: A rope-pulling type sensor structure with adjustable installation position, comprising a sealed shield body, a wire outlet assembly and an installation base, characterized in that: A housing is installed above the inner wall of the sealed shield body through bolts, and a rotary coding module is installed above the sealed shield body, and the wire outlet assembly is arranged on the side of the housing away from the sealed shield body, and an installation piece is installed below the sealed shield body, and the installation base is arranged below the installation piece.

Then, the adjusting bracket is fixed to the limit ball again, so that the wire and the outlet pipe are parallel to each other, thus facilitating the connection of the wire.

At the same time, when assembling the first fixing bracket 7 and the second fixing bracket 8, the angles between the first fixing bracket 7 and the second fixing bracket 8 in the mounting base 6 are adjusted according to the position of the equipment, and then the mounting blocks 9 in the mounting base 6 are connected to the mounting holes 901 by bolts to complete the fixation of the mounting base 6.
