Description

Technical Field

[0001] This utility model relates to the field of photoelectric speed sensor technology, and in particular to a photoelectric speed sensor. Background Technology

[0002] Photoelectric speed sensors can measure various physical quantities such as velocity, acceleration, and displacement. They offer advantages such as non-contact operation, a wide speed measurement range, high accuracy, high resolution, high reliability, and strong anti-interference capabilities, making them widely applicable.

[0003] Traditional photoelectric speed sensors are used by drilling mounting holes in the sensor and securing it with screws. However, once installed, the sensor's detection position cannot be adjusted. If the detection angle needs to be adjusted later, the sensor must be removed and new holes drilled, which is quite cumbersome.

[0004] Therefore, a photoelectric speed sensor is provided to solve the problems mentioned above. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] Reference Figure 1-3 A photoelectric speed sensor includes a sensor body 1, and further includes: a mounting base 2, on which a limiting seat 201 is fixedly connected, and the limiting seat 201 has annularly spaced grooves; a gear seat 102, fixedly connected to the bottom of the sensor body 1, the gear seat 102 matching the grooves of the limiting seat 201; and a mounting ring 3, threadedly connected to the limiting seat 201, the mounting ring 3 being used to fix the gear seat 102 within the limiting seat 201. A connecting rod 101 is fixedly connected to the bottom of the sensor body 1, the gear seat 102 is fixedly connected to the connecting rod 101, a shock-absorbing pad 202 is provided at the bottom of the mounting base 2, and multiple sets of holes are provided on the mounting base 2, with mounting bolts 203 connected to the holes.

[0025] When using this device, first drill a hole at the installation location. After drilling, place the mounting base 2 on it and put the shock-absorbing pad 202 on top. Then fix it with the mounting bolt 203. After fixing, insert the gear seat 102 on the sensor body 1 into the limiting seat 201. After selecting a suitable detection angle, rotate the mounting ring 3 to limit the gear seat 102. Then power on the device to perform the detection.

[0026] If angle adjustment is required, simply rotate the mounting ring 3 in the opposite direction to move it away from the limit seat 201, and pull the gear seat 102 upward. Then, readjust the angle as needed and insert it into the limit seat 201. Finally, rotate the mounting ring 3 again to fix the gear seat 102.

[0027] Example 2

[0028] Reference Figure 1-3 A photoelectric speed sensor, basically the same as in Embodiment 1, but further: the mounting ring 3 is provided with anti-slip texture, and a rubber pad 301 for reducing the shaking of the gear seat 102 is provided inside the mounting ring 3.
