Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of proximity switches, and in particular relates to a proximity switch with an anti-collision structure. Background Art
[0002] A proximity switch is a non-contact electronic position detection device. When an object (such as a metal target) enters its sensing area and reaches a predetermined action distance, the switch can detect the approach of the object and trigger the corresponding action without direct mechanical contact with the moving parts.
[0003] Some proximity switches, especially those with plastic shells, may fail due to physical damage when encountering strong impact or shock. For example, if used in the anti-collision system of heavy machinery such as overhead cranes and cranes, the proximity switch may be damaged if it is accidentally hit, and then lose the anti-collision warning or stop function. Therefore, we hope to design a proximity switch with a new structure to solve this problem. Utility Model Content

A guide rod 310 is welded to the left front side, left rear side, left lower side and left upper side of the anti-collision ring 320 , respectively. An elastic net 340 is welded inside the anti-collision ring 320 .
[0028] See also Figure 1 to Figure 2 A protective tail 130 is provided at the left end of the sheath body 110. The protective tail 130 is a rubber frustum structure. A wiring channel is provided in the middle of the protective tail 130. The inner end of the wiring channel is connected to the inside of the left end of the sheath body 110.
[0029] A switch wire is installed at the left end of the proximity switch body 200, and the switch wire passes through the protective tail 130 through the wiring channel. The left end of the proximity switch body 200 abuts against the right surface of the abutment plate 120, and the outer wall of the abutment plate 120 is slidably connected to the inside of the sheath body 110. By setting the protective cover 100, the proximity switch body 200 located inside the protective cover 100 can avoid direct hard contact between the foreign objects and the proximity switch body 200 when foreign objects approach, thereby protecting the proximity switch.
[0030] A telescopic hole 111 is respectively opened to the left at the right front side, the right rear side, the right upper side and the right lower side of the sheath body 110 , and a spring 2 330 is fixed inside each telescopic hole 111 .
[0031] As the first embodiment of the utility model, by providing a protective cover 100, in actual use, when a foreign object approaches the proximity switch body 200, since the proximity switch is placed inside the protective cover 100, the foreign object will make mechanical contact with the protective cover 100, and the protective cover 100 can prevent the foreign object from directly making hard contact with the proximity switch body 200, thereby protecting the proximity switch.

[0033] One end of each guide rod 310 installed in the telescopic hole 111 is fixedly connected to the outer end of a spring 2 330.
