Abstract
Description
Technical Field
[0001] This utility model relates to the field of photoelectric switch protection, and more specifically, to a photoelectric switch protection mechanism. Background Technology
[0002] A photoelectric switch, also known as a photoelectric sensor, is short for photoelectric proximity switch. Patent publication number CN221499139U discloses a photoelectric switch protection mechanism, including a housing. A horizontal plate is placed on the top of the housing, and sliding rods are fixedly connected to both ends of the bottom of the horizontal plate. The bottom of each sliding rod extends into the interior of the housing and is fixedly connected to a pressure plate. The sliding rods are slidably connected to the housing. A spring is fitted on the outer side of each sliding rod, between the top of the pressure plate and the top of the inner wall of the housing. The bottom of each pressure plate has an arc-shaped structure. Four springs are fixedly connected to the bottom of the inner wall of the housing, and a limit plate is fixedly connected between the tops of the four springs. The top of the limit plate has an arc-shaped structure that cooperates with the pressure plate. This photoelectric switch protection mechanism ensures that the photoelectric switch is pressed firmly without being damaged, and protects the photoelectric switch through the housing, thus extending the lifespan of the photoelectric switch and benefiting practical applications and operation.
[0003] In existing technologies, although stretchable pressure plates can be used to clamp and fix photoelectric switches, in actual use, the distance between the two pressure plates cannot be adjusted. This means that the photoelectric switch clamping process can only accommodate a limited range of switch sizes, reducing the overall applicability of the protective mechanism and thus decreasing the overall practicality of the device.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0032] Example 1:
[0033] Please see Figure 1-6 A photoelectric switch protection mechanism includes a housing 1. A spring 2 is fixedly connected to the bottom surface inside the housing 1. A limit plate 3 is fixedly connected to the top of the spring 2. A fixing block 4 is fixedly installed on the top surface outside the housing 1. A clamping assembly 6 is rotatably installed inside the fixing block 4. A sliding groove 101 is opened in the middle of the top surface of the housing 1. A dustproof cloth 102 is fixedly connected inside the sliding groove 101. Sliding grooves 103 are opened on both the left and right sides of the sliding groove 101 on the top surface inside the housing 1. A pressure assembly 5 is slidably installed inside the sliding groove 103. A filter screen 7 is fixedly installed on the top surface of the housing 1.
[0034] It should be noted that the housing 1, spring 2 and limiting plate 3 in this application are all the same components in the prior art documents. The main structure and function of the left and right ends of the housing 1 are the same as those in the prior art documents. Therefore, the prior art will not be described in detail in this application.
[0035] Specifically, by adapting the dustproof cloth 102 and the sliding groove 101, and by utilizing the extensibility of the dustproof cloth 102 itself to change the state of the sliding rod 601, the sliding groove 101 can be effectively shielded and protected during this process, ensuring the normal use of the filter screen 7.
[0036] The pressurizing assembly 5 includes a sliding collar 501, with a sliding strip 502 fixedly installed at its top end and a spring 503 fixedly installed at its bottom. The shape of the sliding strip 502 matches the shape of the sliding groove 103. A square groove is formed inside the sliding collar 501. The clamping assembly 6 includes a straight rod 601, with a pressure plate 602 fixedly installed at its bottom end. The shape of the straight rod 601 matches the shape of the square groove. A lifting groove 603 is formed on the surface of the straight rod 601. An I-shaped threaded tube 604 is slidably installed inside the lifting groove 603, and a double-threaded screw 605 is threaded inside the I-shaped threaded tube 604. The double-threaded screw 605 has a rotating ring 606 integrally formed in the middle. The top surface of the pressure plate 602 and the bottom end of the second spring 503 are fixedly connected to each other. Both sides of the straight rod 601 are fixedly connected to the dustproof cloth 102 at the corresponding positions. The rotating ring 606 is rotatably installed inside the fixed block 4. The left and right sides of the middle section of the I-shaped threaded tube 604 are fixedly installed with protrusions 609. The protrusions 609 are slidably installed inside the lifting groove 603. There are two straight rods 601. The top ends of the two straight rods 601 are respectively fixedly installed with right angle tie rod 1 607 and right angle tie rod 2 608. The two ends of the right angle tie rod 1 607 and right angle tie rod 2 608 that are close to each other are movably sleeved together.
[0037] Specifically, the sliding strip 502, sliding within the sliding groove 103, effectively limits the height and horizontal position of the pressurizing assembly 5, ensuring it can adapt to changes in the position of the straight rod 601 while applying pressure to the pressure plate 602, guaranteeing its clamping effect. Secondly, the fixing block 4 limits the rotation of the swivel ring 606, thus ensuring the in-situ rotation of the double-threaded screw 605. Similarly, the protrusion 609 limits the vertical sliding of the I-shaped threaded tube 604, preventing it from moving. The rotation prevents rotational deviation as the double-threaded screw 605 rotates, ensuring its transmission effect. Furthermore, the I-shaped structure of the I-shaped threaded tube 604 allows it to move in conjunction with the double-threaded screw 605, driving the straight rod 601 to move as a whole. Finally, the interlocking of right-angle tie rod 1 607 and right-angle tie rod 2 608 allows operators to simultaneously control the two straight rods 601 to pull up without affecting their relative positional movement, thus improving the overall ease of operation of the device.
[0038] The working principle of this utility model is as follows: The appropriate position of the pressure plate 602 is selected and adjusted according to the actual specifications of the photoelectric switch. First, the rotating ring 606 drives the double-threaded screw 605 to rotate. Then, in conjunction with the I-shaped threaded tube 604, the straight rod 601 moves relative to each other until the positions of the two pressure plates 602 are suitable for clamping the photoelectric switch. During this process, the right-angle pull rod 607 and the right-angle pull rod 608 move and fit together to adjust their positions. The sliding strip 502 slides inside the sliding groove 103 until it stops at the appropriate position. The dustproof cloth 102 also contracts and expands accordingly as the position of the straight rod 601 changes. Finally, the operator pulls the right-angle pull rod 607 upwards, causing the right-angle pull rod 607 and the right-angle pull rod 608 to move the straight rod 601 upwards. The pressure plate 602 compresses the spring 503, placing the photoelectric switch on top of the limiting plate 3 and then releasing it. The spring 503 then causes the pressure plate 602 to press down, fixing the photoelectric switch in place.
[0039] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
