Description

Technical Field

[0001] This utility model relates to the field of photoelectric switch technology, specifically to a photoelectric switch assembly. Background Technology

[0002] A photoelectric switch, short for photoelectric proximity switch, detects the presence or absence of an object by utilizing its ability to block or reflect light. A synchronous circuit activates the circuit, allowing detection of the object's presence. The object is not limited to metal; any object that reflects light (or blocks light) can be detected. The photoelectric switch converts the input current into a light signal at the transmitter, which is then emitted. The receiver then detects the target object based on the intensity or presence of the received light.

[0003] Once the existing photoelectric switch body is fixed, it is inconvenient to disassemble and assemble. At the same time, once the photoelectric switch body is fixed, the scanning distance of the photoelectric switch cannot be adjusted, which affects the scanning effect. Utility Model Content

[0004] The purpose of this invention is to provide a photoelectric switch assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photoelectric switch assembly, comprising a base plate, a movable plate, a clamping plate, a clamping block, and a photoelectric switch body. A supporting guard plate is provided at the top of the base plate. Sliding grooves are respectively provided on the side walls of the supporting guard plate. The movable plate is slidably disposed within the sliding grooves. A slot is opened on the movable plate, and a pressing block is slidably disposed within the slot. A spring assembly is provided between the pressing block and the inner wall of the slot. The clamping plate is disposed above the pressing block. The clamping block is fixedly disposed above the clamping plate. The two clamping blocks are arranged opposite each other. An arcuate groove is provided on the clamping block. The photoelectric switch body is disposed between the two arcuate grooves. A protective cylinder is sleeved on the outer wall of the photoelectric switch body. A wire harness plate is fixedly disposed on the upper surface of the supporting guard plate. A connecting line is connected to the tail of the photoelectric switch body.

[0006] As a preferred embodiment, the photoelectric switch body has multiple sets of locking strips equidistantly arranged on its outer wall, the protective cylinder has a placement groove inside, and the placement groove has multiple sets of locking slots equidistantly arranged on its inner wall, the locking slots cooperating with the locking strips.

[0007] As a preferred embodiment, the protective cylinder is provided with heat dissipation grooves, which are connected to the placement circular groove.

[0008] As a preferred embodiment, a dustproof mesh is provided inside the heat dissipation groove.

[0009] As a preferred embodiment, the cable tray has multiple cable tray holes linearly formed, and the cable tray holes are the same size as the connecting lines.

[0010] As can be seen from the technical solution provided by this utility model above, the photoelectric switch assembly provided by this utility model has the following beneficial effects: In this invention, when fixing the photoelectric switch body, a protective sleeve is placed on the outer wall of the photoelectric switch body. The position of the squeezing blocks is manually adjusted so that the squeezing blocks are far apart, squeezing the spring assembly. Then, the protective sleeve is placed between the two clamping blocks. The force applied to the squeezing blocks is released, allowing the spring assembly to return to its original position. The clamping blocks clamp and fix the protective sleeve, thus fixing the photoelectric switch body. The wiring harness is then used to fix the connecting lines, increasing the fixing effect of the photoelectric switch body. When disassembling, the above operation is repeated to squeeze the spring assembly, and the two clamping blocks are far apart, thus disassembling the photoelectric switch body and facilitating the disassembly and replacement of the photoelectric switch body. In this utility model, by setting sliding grooves on both sides of the support plate, the moving plate can move back and forth in the sliding grooves. After the clamping block fixes the photoelectric switch body, the moving plate moves in the sliding grooves to adjust the scanning distance of the photoelectric switch body and ensure the scanning effect of the photoelectric switch. In this invention, a protective sleeve is fitted over the photoelectric switch body. When clamping and fixing the photoelectric switch body, the photoelectric switch body is placed inside the protective sleeve, and then the clamping block clamps and fixes the protective sleeve. This not only fixes the photoelectric switch body but also prevents the clamping block from directly contacting the photoelectric switch body, thus protecting the photoelectric switch body.

[0017] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0018] like Figure 1-5As shown, this utility model embodiment provides a photoelectric switch assembly, including a base plate 1, a movable plate 2, a clamping plate 3, a clamping block 4, and a photoelectric switch body 5. The top of the base plate 1 is provided with a support guard plate 11, and sliding grooves 12 are respectively provided on the two side walls of the support guard plate 11. The movable plate 2 is slidably disposed in the sliding grooves 12. The movable plate 2 has a slot 21, and a pressing block 22 is slidably disposed in the slot 21. A spring assembly 23 is disposed between the pressing block 22 and the inner wall of the slot 21. The clamping plate 3 is disposed above the pressing block 22. The clamping block 4 is fixedly disposed above the clamping plate 3. The two clamping blocks 4 are disposed opposite each other. The clamping block 4 is provided with an arc groove 41. The photoelectric switch body 5 is disposed between the two arc grooves 41. A protective cylinder 6 is sleeved on the outer wall of the photoelectric switch body 5. A wire harness plate 7 is fixedly disposed on the upper surface of the support guard plate 11. A connecting line 8 is connected to the tail of the photoelectric switch body 5.

[0019] To facilitate rapid installation and disassembly of the photoelectric switch body 5, two clamping blocks 4 are used. Each clamping block 4 has an arc groove 41 for clamping and fixing the photoelectric switch body 5. A slot 21 is provided on the moving plate 2, within which a pressing block 22 slides. A spring assembly 23 is positioned between the pressing block 22 and the inner wall of the slot 21. A clamping plate 3 is positioned above the pressing block 22, and the clamping blocks 4 are fixedly positioned above the clamping plate 3. During clamping, the photoelectric switch body 5 is placed inside a protective cylinder 6. The protective cylinder 6 prevents direct contact between the photoelectric switch body 5 and the clamping blocks 4, thus preventing damage to the photoelectric switch body 5 during clamping. The position of the pressing blocks 22 is manually adjusted to move them away from each other, pressing the spring assembly 23. Then, the protective cylinder 6 is placed between the two clamping blocks 4, and the pressure is released. The force applied by block 22 causes spring assembly 23 to return to its original position, clamping block 4 clamps and fixes protective cylinder 6, thereby fixing photoelectric switch body 5. Then, the wiring plate 7 is used to fix the connecting line 8 of photoelectric switch body 5, increasing the fixing effect of photoelectric switch body 5. When disassembling, the above operation is repeated to squeeze spring assembly 23, so that the two clamping blocks 4 are far apart, realizing the disassembly of photoelectric switch body 5, which facilitates the disassembly and replacement of photoelectric switch body 5. In order to adjust the scanning distance of photoelectric switch body 5 after fixing, sliding grooves 12 are set on both sides of the support guard plate 11. The moving plate 2 can move back and forth in the sliding grooves 12. After the clamping block 4 fixes photoelectric switch body 5, the moving plate 2 moves in the sliding grooves 12 to adjust the scanning distance of photoelectric switch body 5, ensuring the scanning effect of photoelectric switch.

[0020] like Figure 5As shown, multiple sets of retaining strips 51 are equidistantly arranged on the outer wall of the photoelectric switch body 5, and a placement circular groove 63 is provided inside the protective cylinder 6. Multiple sets of retaining slots 64 are equidistantly arranged on the inner wall of the placement circular groove 63, and the retaining slots 64 cooperate with the retaining strips 51. To ensure that the photoelectric switch body 5 can be installed inside the protective cylinder 6, multiple retaining strips 51 are equidistantly arranged on the outer wall of the photoelectric switch body 5 and on the inner wall of the placement circular groove 63 of the protective cylinder 6. When installing the photoelectric switch body 5 inside the protective cylinder 6, the photoelectric switch body 5 is placed into the placement circular groove 63, so that the retaining strips 51 on the outer wall of the photoelectric switch body 5 are installed into the retaining slots 54 on the inner wall of the placement circular groove 63, thus achieving convenient and quick installation and fixation.

[0021] like Figure 5 As shown, the protective cylinder 6 has a heat dissipation groove 61, which is connected to the placement groove 63. In order to prevent insufficient heat dissipation of the photoelectric switch body 5 inside the protective cylinder 6 due to poor air circulation, which would affect the use of the photoelectric switch body 5, the heat dissipation groove 61 is provided on the protective cylinder to dissipate heat from the photoelectric switch body 5.

[0022] like Figure 5 As shown, a dustproof mesh 62 is provided inside the heat dissipation groove 61. In order to prevent dust from entering the placement groove 63 through the heat dissipation groove 61, a dustproof mesh 62 is provided inside the heat dissipation groove 61 to prevent dust from entering the placement groove 63.

[0023] like Figure 1 As shown, the cable tray 7 has multiple cable tray holes 71 linearly formed on it, and the cable tray holes 71 are the same size as the connecting lines 8. By linearly forming a cable tray hole 71 on the cable tray 7, when the moving plate 2 moves back and forth in the sliding groove 12 to adjust the scanning distance of the photoelectric switch body 5, different positions of the cable tray hole 71 can be selected to fix the connecting lines 8, ensuring that the cable tray 7 can fix the connecting lines 8 no matter how the photoelectric switch 5 moves.

[0024] The working principle of this embodiment is as follows: During the clamping process of the photoelectric switch body 5, the photoelectric switch body 5 is placed in the placement groove 63 inside the protective cylinder 6, so that the retaining strip 51 on the outer wall of the photoelectric switch body 5 engages in the retaining groove 64 on the inner wall of the placement groove 63, so that the photoelectric switch body 5 is installed in the protective cylinder 6. The position of the pressing block 22 is manually adjusted so that the pressing blocks 22 are far apart, and the spring assembly 23 is pressed. Then, the protective cylinder 6 is placed between the two clamping blocks 4. The force applied to the pressing block 22 is released, so that the spring assembly 23 returns to its original position. The clamping blocks 4 clamp and fix the protective cylinder 6, thereby achieving the fixation of the photoelectric switch body 5. Then, the wires on the wire harness plate 7 are used to fix the photoelectric switch body 5. Hole 71 secures the connecting line 8 of the photoelectric switch body 5, enhancing the securing effect of the photoelectric switch body 5. When disassembling, the above operation is repeated to squeeze the spring assembly 23, causing the two clamping blocks 4 to move away from each other, thus enabling the disassembly of the photoelectric switch body 5 and facilitating its replacement. To adjust the scanning distance of the fixed photoelectric switch body 5, sliding grooves 12 are provided on both sides of the support plate 11. The moving plate 2 can move back and forth within the sliding grooves 12. After the clamping blocks 4 secure the photoelectric switch body 5, the moving plate 2 moves within the sliding grooves 12 to adjust the scanning distance of the photoelectric switch body 5, ensuring the scanning effect of the photoelectric switch.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
