Description

Technical Field

[0001] The utility model belongs to the technical field of sensors, and particularly relates to a linear displacement sensor convenient for assembly. Background Art

[0002] A displacement sensor, also known as a linear sensor, is a linear device belonging to metal induction. The function of the sensor is to convert various measured physical quantities into electric quantities. During the production process, the measurement of displacement is generally divided into two types: measuring the physical size and mechanical displacement. Specifically, when in use, the induction sheet is fixedly installed on the device to be measured, and the movement distance of the device to be measured is measured by sensing the movement of the induction sheet through the induction coil. Then, it is connected to the control system through the PCB to accurately control the movement distance of the device to be measured.

[0003] When the existing linear displacement sensor is installed on the corresponding fixed component, it is generally directly fixedly connected by bolts. This method of assembly is not convenient for positioning, and when the bolts are loose, relative movement or rotation will occur between the linear displacement sensor and the fixed component, thus affecting the measurement accuracy of the linear displacement sensor. For this reason, we propose a linear displacement sensor convenient for assembly. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1 - 3 , the present invention provides a technical solution: a linear displacement sensor convenient for assembly, including a mounting bracket 1 and a sensor body 2. The surface of the mounting bracket 1 is provided with mounting holes 14. Both sides of the mounting bracket 1 are provided with fixing plates 3. The surface of the fixing plates 3 is provided with fixing holes 4. Both sides of the sensor body 2 are provided with connecting rods 5. The bottom of the connecting rod 5 is provided with a plug pin 6. The plug pin 6 is arranged inside the mounting hole 14. Inside the plug pin 6 is provided with a fixing shaft 7. The surface of the fixing shaft 7 is provided with a limiting block 8. The top of the limiting block 8 is provided with a spring 9. The surface of the fixing shaft 7 is provided with a slider 10. Both sides below the plug pin 6 are provided with receiving holes 11. Both sides of the slider 10 are provided with limiting rods 12. The surface of the fixing shaft 7 is provided with a sliding rod 13.

[0019] Specifically, the surface of the mounting bracket 1 is fixedly provided with mounting holes 14. Both sides of the mounting bracket 1 are fixedly connected with fixing plates 3. The surface of the fixing plates 3 is fixedly provided with fixing holes 4. Both sides of the sensor body 2 are fixedly connected with connecting rods 5. The bottom of the connecting rod 5 is fixedly penetrated and connected with a plug pin 6. One side of the surface of the plug pin 6 is fixedly provided with a thread ring 15. The surface of the thread ring 15 is threadedly connected with a nut 16. The inner bottom of the plug pin 6 is fixedly installed with a fixing shaft 7. The surface of the fixing shaft 7 is fixedly sleeved with a limiting block 8. The top of the limiting block 8 is fixedly connected with a spring 9. The spring 9 is sleeved on the surface of the fixing shaft 7. The surface of the fixing shaft 7 is slidably connected with a slider 10. The bottom of the slider 10 and the top end of the spring 9 are fixedly connected. Both sides below the plug pin 6 are fixedly provided with receiving holes 11. Both sides of the slider 10 are rotatably connected with limiting rods 12. The limiting rods 12 are arranged inside the receiving holes 11. The surface of the fixing shaft 7 is slidably connected with a sliding rod 13. The top end of the sliding rod 13 extends above the plug pin 6.

[0020] In this embodiment, by means of the provided fixing plate 3 and fixing holes 4, the mounting bracket 1 can be fixedly installed on one side of the connecting piece by using screws. Then, the pins 6 on both sides of the sensor body 2 are aligned with the mounting holes 14, and the sliding rod 13 is pressed downward. The sliding rod 13 will drive the slider 10 on the surface of the fixed shaft 7 to slide towards the limiting block 8. While the slider 10 drives the spring 9 to compress, it will also drive the limiting rods 12 on both sides of itself to retract into the receiving holes 11. At this time, the pins 6 are inserted into the mounting holes 14. When the upper part of the receiving hole 11 moves downwards beyond the bottom of the mounting bracket 1, the pressing on the sliding rod 13 is released, and the spring 9 will drive the slider 10 and the limiting rods 12 to reset, causing the limiting rods 12 to extend outwards on both sides. As Figure 2 shown, the sensor body 2 drives the pins 6 to rise, so that the top ends of the limiting rods 12 firmly abut against the bottom of the mounting bracket 1. Then, the nut 16 is rotated downward so that the bottom of the nut 16 firmly abuts against the top surface of the mounting bracket 1, thus completing the installation of the sensor body 2.
