During the detection process of the proximity switch, they are inevitably affected by bumps and collisions. Due to the lack of protective structures, the proximity switch is easily damaged, which can cause the proximity switch to malfunction and fail, thereby affecting its normal operation and accurate detection.
[0004] Therefore, we provide a proximity switch device with anti-collision protection. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The proximity switch device with anti-collision protection, through the setting of the movable ring and the fixed seat, when the front side of the proximity switch is hit, the hit object will directly contact the movable ring, and the moment the hit occurs, it will squeeze the movable ring to slide toward the fixed seat. At this time, the spring will be compressed and deformed to absorb part of the impact force. During the collision, the hit object cannot contact the proximity switch at all times due to the protection of the movable ring, which effectively protects the front side of the proximity switch from being damaged. Such an anti-collision protection device can extend the service life of the proximity switch and ensure its normal operation, and it can continue to work even when it is hit by external impact.

DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1-5 As shown, the utility model provides an embodiment: a proximity switch device with anti-collision protection, comprising a proximity switch 1, a fixed seat 3 and a movable ring 4, the outer side of the proximity switch 1 is fixedly installed with a fixed ring 2, the outer side of the fixed ring 2 is threadedly installed with the fixed seat 3, the front side of the fixed seat 3 is slidably installed with the movable ring 4, and the outer side of the movable ring 4 is elastically installed with an arc pad 5.
[0024] Furthermore, an external threaded buckle 21 is provided on the outer side of the fixing ring 2, and an internal threaded buckle 31 is provided on the inner side of the fixing seat 3, and the external threaded buckle 21 and the internal threaded buckle 31 are threadedly connected. When the fixing seat 3 is damaged, the fixing seat 3 can be manually rotated to disengage the threaded fit between the external threaded buckle 21 and the internal threaded buckle 31, thereby removing the fixing seat 3.
[0025] Furthermore, guide grooves 32 are provided around the fixing seat 3 to provide a sliding path for the guide block 41. Slide grooves 33 are provided on both sides of the guide groove 32 to provide a sliding path for the pulley 42. A spring limit pin 34 is welded to the top of the guide groove 32.
[0026] Furthermore, a guide block 41 is welded on the inner side of the movable ring 4 , and the guide block 41 is slidably installed inside the guide groove 32 . When the movable ring 4 is hit, the movable ring 4 will drive the guide block 41 to slide inside the guide groove 32 .
[0027] Furthermore, pulleys 42 are installed on both sides of the guide block 41 through short axis rotation, and the pulleys 42 are slidably installed inside the slide groove 33. When the guide block 41 slides, it will drive the pulley 42 to slide inside the slide groove 33. The rotation of the pulley 42 will make the guide block 41 move more smoothly.
[0028] Furthermore, a spring limit pin 2 43 is welded on the side of the guide block 41 away from the movable ring 4, a spring 1 44 is sleeved on the outer side of the spring limit pin 2 43, and the other end of the spring 1 44 is sleeved on the outer side of the spring limit pin 1 34, and the spring 1 44 abuts between the guide groove 32 and the guide block 41. When colliding with the movable ring 4, the guide block 41 slides to compress the spring 1 44. When the collision force disappears, the spring 1 44 recovers its deformation, thereby resetting the movable ring 4. During the compression process of the spring 1 44, the spring limit pin 2 43 abuts against the spring limit pin 1 34, thereby preventing the spring 1 44 from continuing to be compressed, thereby effectively protecting the compression value of the spring 1 44.
[0029] Furthermore, spring limit pins 3 45 are welded around the outer side of the movable ring 4, and spring limit pins 4 51 are welded on the inner side of the arc pad 5. A spring 2 52 is sleeved on the outer side of the spring limit pin 41, and the other end of the spring 2 52 is sleeved on the outer side of the spring limit pin 3 45, and the spring 2 52 abuts between the movable ring 4 and the arc pad 5. When the proximity switch 1 is subjected to collision from top to bottom, left to right, the spring 2 52 is compressed and deformed, and at the same time, it will absorb some impact force. Through the mutual cooperation between the arc pad 5 and the spring 2 52, the proximity switch 1 can be effectively protected around.
[0030] Working principle: First, a proximity switch device with anti-collision protection is moved to the working position. In the first step, when the proximity switch 1 is working, the fixed seat 3 and the movable ring 4 are installed at the front end of the proximity switch 1 to continuously protect the proximity switch 1. In the second step, when the proximity switch 1 is hit by the front end, the movable ring 4 will drive the guide block 41 to slide inside the guide groove 32. At this time, the spring 1 44 is compressed. While compressing and deforming, the spring 1 44 will absorb a little impact force. When the spring limit pin 1 34 abuts against the spring limit pin 2 43, the guide block 41 will be free. The front end of the fixing seat 3 still exceeds the front end position of the proximity switch 1, which effectively protects the front end of the proximity switch 1. In the third step, when the proximity switch 1 is hit by the top, bottom, left, and right collisions, it will directly contact the arc pad 5 and compress the arc pad 5. At the same time, the spring 2 52 is compressed and deformed. While compressing and deforming, the spring 2 52 absorbs a little impact force. Through the cooperation between the arc pad 5 and the spring 2 52, the proximity switch 1 can be effectively protected all around. In this way, the use process of a proximity switch device with anti-collision protection is completed.
