Description

Technical Field

[0001] The utility model relates to the technical field of displacement sensors, in particular to a reflective displacement sensor. Background Art

[0002] A reflective displacement sensor is a sensor that uses optical principles to measure the position or displacement of an object. It determines the position of an object by measuring the changes in light reflected from the target object.

[0003] However, existing reflective displacement sensors are usually fixed on a base. This fixed installation method limits the sensor's ability to adjust its position after installation. This means that once the installation is complete, the sensor's position and angle cannot be further fine-tuned, which may affect the measurement accuracy. In actual use, if the sensor fails to perfectly align with the target object, or the initial position is not ideal due to installation errors, it will directly affect the accuracy of the measurement results. Utility Model Content

[0007] The technical effect of adopting the above further solution is that the limit block can be pressed down to slide downward on the outer surface of the support rod.

[0008] As a preferred implementation, the other end of the return spring is fixedly mounted on the top outer surface of the flange, and a second crank is movably embedded on the inner top side of the fixed structure.

[0010] As a preferred embodiment, a forward-rotating screw rod is fixedly mounted on the bottom of the second crank handle, and a reverse-rotating screw rod is fixedly mounted on the bottom of the forward-rotating screw rod.

[0011] The technical effect of adopting the above further solution is: the forward-rotating screw rod is transmitted to the reverse-rotating screw rod.

[0012] As a preferred embodiment, the outer surface of the bottom of the reversing screw rod is movably embedded in the bottom side of the inner wall of the fixed structure, and a second sliding groove is opened on the right side inside the fixed structure.

[0013] The technical effect of adopting the above further solution is that the second sliding block can be made to slide in a relative direction through the second sliding groove.

[0014] As a preferred embodiment, second sliding blocks are slidably connected to both sides of the inner surface of the second sliding groove, and one of the second sliding blocks is threadedly connected to the outer surface of the forward-rotating screw rod.

[0015] The technical effect of adopting the above further solution is that the forward screw rod and the reverse screw rod can drive the second slider to move when they rotate.

[0016] As a preferred implementation, another of the second sliding blocks is threadedly connected to the outer surface of the reversing screw, and a clamping plate is fixedly installed on the right side of the two second sliding blocks.

[0017] The technical effect of adopting the above further solution is that the clamping plate can be driven to move synchronously by the second slider.

[0018] As a preferred implementation, rubber pads are fixedly mounted on opposite sides of the two clamping plates, and the inner sides of the two rubber pads are movably connected to the displacement sensor body.

[0019] The technical effect of adopting the above further solution is that the rubber pad can fit the outer surface of the displacement sensor body to clamp and fix it.

[0020] Compared with the prior art, the advantages and positive effects of the utility model are:

[0021] 1.

When in use, the utility model can realize the rapid disassembly and installation of the displacement sensor body through structures such as the forward-rotating screw and the reverse-rotating screw. The simplified installation and disassembly process reduces the complexity of the operation, allowing the user to complete the task more easily and significantly improving work efficiency.
