Description

Technical Field

[0001] The utility model relates to the technical field of switch protection, in particular to a photoelectric switch protection device. Background Art

[0002] A switching power supply is also called a switching power supply or a switching converter, while a photoelectric switch (photoelectric sensor) is the abbreviation of a photoelectric proximity switch. It uses the obstruction or reflection of the light beam by the object being detected to connect the circuit by a synchronous loop, thereby detecting the presence or absence of an object. Objects are not limited to metals, and all objects that can reflect light (or block light) can be detected.

[0003] Photoelectric switches on the market generally do not have a protective structure, and are easily damaged by bumps during use. For example, the Chinese utility model patent CN216435710U discloses a protective device for a photoelectric switch, which wraps the photoelectric switch body with a bottom plate and a cover to prevent the photoelectric switch body from being damaged by collisions or dust accumulation during use and affecting the use effect. During the installation process, the first screw is adjusted, and the first screw interacts with the first threaded hole on the bottom plate and drives the lifting plate and the movable plate to move up and down, thereby adjusting the installation height of the photoelectric switch body. Then, the second screw is adjusted, and the second screw interacts with the second threaded hole on the movable plate and drives the movable plate and the fixed plate to move left and right, thereby adjusting the left and right distance of the photoelectric switch body, achieving a simple and convenient protection and multi-directional adjustment effect.

[0004] Existing protective devices for photoelectric switches do not have a good fixing function. For example, the above-mentioned patent can provide a cover and protection for the photoelectric switch. However, in actual use, when the photoelectric switch needs to be repaired, the disassembly method is relatively complicated and requires the use of external tools to achieve disassembly, which has certain limitations.

[0028] When in use, the round-headed rod 24 on the shell 1 21 is pulled outward, and then the bottom plate 11 is inserted between the two shells 1 21, and the round-headed rod 24 is released. The rear end of the round-headed rod 24 is inserted into the bottom plate 11 through the resilience of the spring 1 25 to complete the installation of the bottom plate 11, and then the round-headed rod 24 on the shell 2 22 is pulled outward, and the protective cover 13 is inserted between the two shells 22, and the round-headed rod 24 is released. The resilience of the spring 1 25 allows the round-headed rod 24 to be inserted into the protective cover 13 to complete the installation of the protective cover 13. At this time, the protective cover 13 covers and protects the photoelectric switch body 12. When the protective cover 13 needs to be removed, the round-headed rod 24 on the shell 2 22 is directly pulled outward, and then the protective cover 13 is pushed to realize the removal of the protective cover 13. When disassembling, pull the round-headed rod 24 on the shell 1 21 outward, and then push the bottom plate 11 out from between the two shells 21 to achieve the disassembly of the bottom plate 11.
