Description

Technical Field

[0001] The utility model relates to the technical field of inductive proximity switches, in particular to an inductive proximity switch. Background Art

[0002] Among all types of switches, there is a component that has the ability to "sense" objects approaching it - the displacement sensor. The displacement sensor uses its sensitive characteristics to approaching objects to control the switch on or off. This is the proximity switch. When in a special usage environment, the moving parts on the machine cannot be directly connected to an ordinary switch to control the switch on or off.

[0003] The China Patent Network discloses an inductive proximity switch with the publication number CN221900856U. Although it adopts an adjustable structure, when the proximity switch is installed in different environments, the proximity switch can be fixed first, and then the handle is turned to drive the shaft to rotate, so that the connecting wire can be extended and adjusted from the lower through-hole. After adjusting to the appropriate length, the handle is fixed to prevent the shaft from rotating, and the connecting plate on the storage box is fixed to the load-bearing object near the power supply by bolts, and then the plug is connected to the power supply, which effectively achieves the effect of freely adjusting the wiring length according to the on-site use environment and the distance to the proximity object to achieve the optimal use length. However, when in use, the connecting wire of this patent is frequently softly wound on the shaft. After long-term use, the connecting wire may be entangled and locked, thereby affecting the overall work efficiency.

[0004] To this end, an inductive proximity switch is proposed. Utility Model Content

[0036] See also Figure 1 、 3-5. The utility model provides a technical solution: an inductive proximity switch, wherein a first baffle 11 and a second baffle 12 are provided at opposite ends of an upper plate 1 and a lower plate 2, and a first fixing component and a second fixing component are provided at ends of the upper plate 1 and the lower plate 2 away from each other, respectively.

[0038] Working principle:

[0039] By changing the overall structural design, two spring-shaped first wires 6 and second wires 8 are used. The first wires 6 and second wires 8 are designed independently of each other. On the one hand, due to their independent arrangement, the first wires 6 and second wires 8 do not affect each other when working, thereby preventing entanglement and locking. On the other hand, the first wires 6 and second wires 8 themselves have telescopic properties, and when telescoping, they telescope vertically. Compared with the traditional winding method, they will not cause entanglement and locking. In summary, compared with the existing method, the present invention will not cause entanglement and locking during long-term use, thereby improving the overall work efficiency.

[0040] By pulling the first pull plate 17, the first pull plate 17 will drive the first connecting rod 16 to move. At this time, the first compression spring 18 will perform a corresponding stretching movement. After one end of the first connecting rod 16 is disengaged from the first clamping hole 15, the first baffle 11 can be disassembled. Similarly, by pulling the second pull plate 22, the second pull plate 22 will drive the second connecting rod 21 to move. At this time, the second compression spring 23 will perform a corresponding stretching movement.
