Description

Technical Field

[0001] This utility model relates to the field of photoelectric sensor control board technology, and in particular to a photoelectric sensor control board that is easy to install. Background Technology

[0002] A photoelectric sensor is a device that converts light signals into electrical signals. Its working principle is based on the photoelectric effect. The photoelectric effect refers to the phenomenon where electrons in a substance absorb the energy of photons and produce a corresponding electrical effect when light shines on it. The photoelectric effect is usually classified into three categories based on the different phenomena observed: external photoelectric effect, internal photoelectric effect, and photovoltaic effect. The photoelectric sensor control board is the control component of the photoelectric sensor.

[0003] However, in the existing technology, the photoelectric sensor control board is usually a circuit board. During use, a protective shell is usually added to protect it to improve its service life. When installing these shells containing photoelectric sensor control boards, multiple sets of screws are generally used to fix them. The method of fixing with multiple sets of screws is relatively troublesome during installation and disassembly. It is necessary to match the screws and screw holes one by one or disassemble them one by one, which takes a lot of time and brings certain troubles to installation and disassembly, and has certain limitations. Therefore, we propose a photoelectric sensor control board that is easy to install. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the existing technology, when installing these housings equipped with photoelectric sensor control boards, multiple sets of screws are generally used to fix them. The method of fixing with multiple sets of screws is relatively troublesome during installation and disassembly. It is necessary to match the screws and screw holes one by one or disassemble them one by one, which takes a lot of time and brings certain troubles to installation and disassembly. Therefore, this utility model proposes a photoelectric sensor control board that is easy to install.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a photoelectric sensor control board that is easy to install, comprising a lower housing and a fixing frame. The lower housing is snapped into the upper end of the fixing frame. Insert rods are fixedly installed at the lower ends of both ends of the lower housing. A slot is formed at the lower end of the insert rod. A limiting hole is formed in the middle of one side of the insert rod. Slots are formed on both sides of the middle of the upper end of the fixing frame. Slide grooves are formed at both ends of the fixing frame. The slots and slide grooves are connected. The insert rod is slidably snapped into the middle of the slot. A slide rod is slidably snapped into the middle of the slide groove. A spring is fixedly installed at one end of the slide rod. One end of the spring is fixedly connected to one end of the slide groove. A limiting groove is formed on one side of the upper end of the middle of the slide groove. A slider is fixedly installed above the end of the slide rod near the spring. A limiting rod is fixedly installed on one side of the upper end of the slider. The slider is inserted into the middle of the limiting hole. A pressing block is fixedly installed at the other end of the slide rod.

[0006] Preferably, the slide bar is located in the middle of the slot, and the slider abuts against both sides of the limiting slot.

[0007] Preferably, limit blocks are fixedly installed above and below the pressing block, and the limit blocks abut against the surface fixing frame.

[0008] Preferably, a control board body is fixedly installed in the middle of the lower housing, and multiple line interfaces are evenly fixedly installed at one end of the lower housing.

[0009] Preferably, a cover plate is snapped onto the upper end of the lower housing, and screw holes are provided at the four corners of the lower housing and the cover plate, with screws threaded into the center of the screw holes.

[0010] Preferably, fixing plates are fixedly installed at the bottom of both ends of the fixing frame.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, when fixing the lower and upper housings containing the control board body, first fix the fixing bracket, then align the two insert rods at the bottom of the lower housing with the slots and insert them. At this time, due to the presence of the limiting rod, the insert rods cannot touch the bottom. The user can press the pressing block inward. During the process, the spring will contract and drive the sliding rod to move in the direction of spring compression. At this time, the insert rod can touch the bottom. Release the limiting of the pressing block to reset the spring and drive the sliding rod and the limiting rod to reset. After the limiting rod is reset, it will be stuck in the limiting hole opened by the insert rod, thereby limiting the lower housing and completing the installation. When disassembling, press the two pressing blocks inward to release the limiting rod from limiting the insert rod and remove the lower housing. Through the design of the quick-release structure, the installation and disassembly of the lower housing and cover plate containing the control board body are simplified.

[0013] 2. In this utility model, during the pressing and releasing of the limiting pressing block, the slider will abut against both ends of the limiting groove, thereby limiting the position of the sliding rod and the limiting rod. This makes it easier for installers to judge whether the travel of the sliding rod is sufficient when pressing the pressing block, and has higher practicality.

[0014] 3. In this utility model, the limiting blocks set above and below the pressing block can limit the pressing block and prevent the pressing block from being completely submerged in the groove when it is squeezed. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as Figure 1-4 As shown, this utility model provides an easy-to-install photoelectric sensor control board, including a lower housing 1 and a fixing frame 16. The lower housing 1 is snapped into the upper end of the fixing frame 16. Insert rods 2 are fixedly installed at the lower ends of both ends of the lower housing 1. The lower end of the insert rod 2 has a slot 21. A limit hole 22 is opened in the middle of one side of the insert rod 2. Slots 23 are opened on both sides of the middle of the upper end of the fixing frame 16. Slide grooves 24 are opened at both ends of the fixing frame 16. The slots 23 and slide grooves 24 are connected. The insert rod 2 slides and locks. A slide rod 26 is slidably engaged in the middle of the slot 23 and the middle of the slide groove 24. A spring 27 is fixedly installed at one end of the slide rod 26. One end of the spring 27 is fixedly connected to one end of the slide groove 24. A limit groove 25 is opened on one side of the upper part of the middle of the slide groove 24. A slider 29 is fixedly installed above the end of the slide rod 26 near the spring 27. A limit rod 30 is fixedly installed on one side of the upper end of the slider 29. The slider 29 is inserted into the middle of the limit hole 22. A pressing block 28 is fixedly installed at the other end of the slide rod 26.

[0023] The specific setup and function of this embodiment will be described in detail below. When fixing the lower housing 1 and upper housing 11, which contain the control board body 14, the fixing bracket 16 is fixed first. Then, the two insert rods 2 at the bottom of the lower housing 1 are aligned with the slots 23 and inserted. At this time, due to the presence of the limiting rod 30, the insert rods 2 cannot reach the bottom. The user can press the pressing block 28 inward. During this process, the spring 27 will contract, thereby causing the sliding rod 26 to move in the direction where the spring 27 is compressed. This causes the slider 29 and the upper limiting rod 30 to move inward. At this time, the insertion... When rod 2 touches the bottom, releasing the limit on the pressing block 28 resets the spring 27 and drives the sliding rod 26 and the limiting rod 30 to reset. After the limiting rod 30 resets, it will be stuck in the limiting hole 22 opened in the insertion rod 2, thereby limiting the lower housing 1 and completing the installation. When disassembling, pressing the two pressing blocks 28 inwards will release the limiting rod 30 from limiting the insertion rod 2, and the lower housing 1 can be removed. Through the design of the quick-release structure, the installation and disassembly of the lower housing 1 and the cover plate 11 containing the control board body 14 are simplified, and the practicality is improved.

[0024] Example 2, as Figure 1 , Figure 2 and Figure 3 As shown, the slide bar 26 is located in the middle of the slot 21, the slider 29 abuts against both sides of the limiting slot 25, the pressing block 28 is fixedly installed above and below the limiting block 31, the limiting block 31 abuts against the surface fixing bracket 16, the control board body 14 is fixedly installed in the middle of the lower housing 1, a plurality of line interfaces 15 are evenly fixedly installed at one end of the lower housing 1, the upper end of the lower housing 1 is snapped with a cover plate 11, the lower housing 1 and the cover plate 11 are provided with screw holes 12 at the four corners, the screw holes 12 are threaded with screws 13 in the middle, and the fixing plates 17 are fixedly installed at the lower ends of both ends of the fixing bracket 16.

[0025] The overall effect of this embodiment is that the control board body 14 is installed in the middle of the lower housing 1 and the cover plate 11 at the factory, and is equipped with a fixing bracket 16 for protection. The user can connect the wires according to the line interface 15. When fixing the lower housing 1 and the upper housing 11, which contain the control board body 14, first fix the fixing bracket 16, and then insert the two plug rods 2 below the lower housing 1 into the slots 23. At this time, due to the presence of the limiting rod 30, the plug rods 2 cannot reach the bottom. The user can press the pressing block 28 inward. During the process, the spring 27 will contract, thereby driving the slide rod 26 to move in the direction of the spring 27 compression, and then causing the slider 29 and the upper limiting rod 30 to move inward. At this time, the plug rods 2 can reach the bottom. Then release the limiting of the pressing block 28 to reset the spring 27 and drive the slide rod 26 and the limiting rod 30 to reset. After resetting, 30 will be stuck in the limiting hole 22 opened in the insertion rod 2, thereby limiting the lower housing 1, and the installation can be completed. When disassembling, press the two pressing blocks 28 inward to make the limiting rod 30 release the limiting of the insertion rod 2, and the lower housing 1 can be removed. Through the design of the quick-release structure, the installation and disassembly of the lower housing 1 and the cover plate 11 with the control board body 14 are simplified, and the practicality is improved. During the pressing and releasing of the limiting pressing block 28, the slider 29 will abut against the two ends of the limiting groove 25, thereby limiting the position of the sliding rod 26 and the limiting rod 30. This makes it easier for the installer to judge whether the stroke of the sliding rod 26 is sufficient when pressing the pressing block 28, and the practicality is improved. The limiting blocks 31 set above and below the pressing block 28 can limit the pressing block 28 and prevent the pressing block 28 from being completely submerged in the sliding groove 24 when it is pressed.

[0026] The usage and working principle of this device are as follows: The control board body 14 is installed in the middle of the lower housing 1 and the cover plate 11 at the factory, and is equipped with a fixing bracket 16 for protection. The user can connect the wires according to the wiring interface 15. When fixing the lower housing 1 and the upper housing 11, which contain the control board body 14, first fix the fixing bracket 16, and then insert the two plug rods 2 at the bottom of the lower housing 1 into the slots 23. At this time, due to the presence of the limiting rod 30, the plug rods 2 cannot reach the bottom. The user can press the pressing block 28 inward. During the process, the spring 27 will contract, thereby driving the slide rod 26 to be compressed towards the spring 27. The movement of the slider 29 and the upper limit rod 30 inward causes the insertion rod 2 to touch the bottom. Then, the limit on the pressing block 28 is released, causing the spring 27 to reset and drive the sliding rod 26 and the limit rod 30 to reset. After the limit rod 30 is reset, it will be stuck in the limit hole 22 opened in the insertion rod 2, thereby limiting the lower housing 1, and the installation can be completed. When disassembling, the two pressing blocks 28 are pressed inward to release the limit rod 30 from limiting the insertion rod 2, and the lower housing 1 can be removed. Through the design of the quick-release structure, the installation and disassembly of the lower housing 1 and the cover plate 11 containing the control board body 14 are simplified, and the practicality is improved.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
