Description

Technical Field

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

[0002] A photoelectric switch is a type of sensor that converts changes in light intensity between the transmitter and receiver into changes in current for detection. A photoelectric switch is short for photoelectric proximity switch; it utilizes the blocking or reflection of a light beam by the object being detected, with a synchronous circuit activating the circuit to detect the object's presence. The object is not limited to metal; any object that can reflect light or make a connection can be detected.

[0003] The prior art, disclosed in CN216158046U, provides a photoelectric switch that is easy to disassemble, relating to the field of photoelectric switch disassembly technology. It addresses the current problem that photoelectric switches cannot be disassembled during use, leading to the inability to promptly replace aging or damaged internal electronic components, increasing operating costs, and the difficulty in detaching the device from the bracket during installation. The proposed solution includes a photoelectric switch body, one end of which is connected to a first fixing component, which is a spring-adjustable structure. The photoelectric switch body is movably connected to a bracket via the first fixing component, and a second fixing component is provided at the end of the photoelectric switch body. This device not only facilitates the disassembly of the photoelectric switch itself for maintenance of its internal electronic components, reducing operating costs, but also facilitates the disassembly and installation of the photoelectric switch from the bracket, improving the device's practicality.

[0004] In the aforementioned patent, the first spring is compressed by pressing the pressing block, which in turn moves the limiting block out of the third limiting hole and removes the connecting cover, thereby facilitating the disassembly of the photoelectric switch from the bracket. However, this method of disassembling the photoelectric switch requires the photoelectric switch to be installed in the annular connecting block and connecting rod before disassembly, and then it needs to be combined with the corresponding structure on the bracket to achieve the purpose of easy disassembly. Therefore, the overall assembly process of the easy-to-disassemble photoelectric switch is relatively cumbersome, reducing the overall practicality of the easy-to-disassemble photoelectric switch. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a photoelectric switch that is easy to disassemble, thus solving the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a detachable photoelectric switch includes a mounting assembly, a locking assembly fixedly mounted on the mounting assembly, and a switch body detachably mounted within the locking assembly. The switch body includes an outer cylinder with threads on its outer surface. The locking assembly includes an outer wall, a lower locking member fixedly mounted at the bottom center of the outer wall, and a lower thread on the top of the lower locking member. A lower pressing assembly is fixedly mounted on the top of the outer wall, and the lower pressing assembly includes a top assembly movable within the outer wall. The top assembly includes an upper locking member with an upper thread on its bottom. The lower and upper locking members clamp and fix the switch body, and both the lower and upper threads are adapted to the thread. This adaptation of the lower and upper threads to the thread allows the switch body to be more securely fixed within the locking assembly, improving the detachable photoelectric switch's installation stability.

[0007] Furthermore, the downward pressing assembly also includes a fixing plate fixedly mounted on the outer wall. Multiple telescopic shafts for support are fixedly mounted on the end of the fixing plate near the top assembly. A spring column is fixedly mounted at the center of the end of the fixing plate near the top assembly. The telescopic shafts are located on both sides of the spring column. The ends of the spring columns away from the fixing plate are fixedly mounted on the top assembly, and the ends of the telescopic shafts away from the fixing plate are also fixedly mounted on the top assembly. The fact that the ends of the spring columns away from the fixing plate are fixedly mounted on the top assembly ensures that the elastic force of the spring columns constantly acts on the top assembly, causing the top assembly to move downwards continuously. This improves the integrity of the internal structure of the easily disassembled photoelectric switch.

[0008] Furthermore, slide rails are fixedly installed on both sides of the inner side of the outer wall, and sliding grooves are formed on both sides of the locking member. The sliding grooves are adapted to the slide rails, and the locking member moves at the upper limit of the slide rails through the sliding grooves. The locking member's movement at the upper limit of the slide rails through the sliding grooves improves the accuracy of the internal structure movement of the easily disassembled photoelectric switch.

[0009] Furthermore, the mounting assembly includes a mounting plate fixedly mounted below the locking assembly, the mounting plate having multiple mounting holes, which are used with bolts to fix the mounting plate to the wall.

[0010] Furthermore, a connecting wire is fixedly installed at the end of the outer cylinder away from the thread. This connecting wire is used for electrical connection between the switch body and external electronic devices. A mounting cylinder is fixedly installed at the end of the outer cylinder away from the connecting wire, and a mounting head is detachably mounted on the mounting cylinder. The detachable mounting head on the mounting cylinder improves the ease of disassembly of the switch body itself.

[0011] Furthermore, the mounting head has a threaded groove on its outer side, and the mounting cylinder has a threaded groove on its inner side. The mounting head is threadedly connected to the mounting cylinder, and a sensing head is fixedly mounted on the end of the mounting head away from the mounting cylinder.

[0012] Furthermore, both the lower locking member and the upper locking member have an arc-shaped plate at one end that contacts the switch body. This arc-shaped plate design allows the switch body to be more securely fixed within the locking assembly, improving the stability of the photoelectric switch installation and enhancing its ease of disassembly. Beneficial effects

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention uses a locking assembly to clamp the switch body inside, and the lower and upper locking parts clamping the switch body are threaded together. The threads on the switch body itself make the switch body more securely fixed between the lower and upper locking parts. The top assembly, which can move up and down via a spring post, makes it easier for users to assemble and disassemble the switch body without the need to install any other structure on the switch body, thus improving the practicality of the easily disassembled photoelectric switch.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0023] Example

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6This application will be further described in detail below. A photoelectric switch that is easy to disassemble includes a mounting assembly 1. A locking assembly 3 is fixedly mounted on the mounting assembly 1. A switch body 2 is detachably mounted inside the locking assembly 3. The switch body 2 includes an outer cylinder 23 with threads 22 on its outer surface. The locking assembly 3 includes an outer wall 35. A lower locking member 31 is fixedly mounted at the bottom center of the outer wall 35. A lower thread 32 is formed on the top of the lower locking member 31. A lower pressing assembly 34 is fixedly mounted on the top of the outer wall 35. The lower pressing assembly 34 includes a top assembly 344 that moves within the outer wall 35. The top assembly 344 includes an upper locking member 3442. The bottom of component 3442 has an upper thread 3441. The lower locking member 31 and the upper locking member 3442 are used to clamp and fix the switch body 2. The lower thread 32 and the upper thread 3441 are both adapted to the thread 22. The pressing assembly 34 also includes a fixing plate 341 fixedly installed on the outer wall 35. Multiple telescopic shafts 342 for support are fixedly installed on one end of the fixing plate 341 near the top assembly 344. A spring column 343 is fixedly installed at the center of the end of the fixing plate 341 near the top assembly 344. The telescopic shafts 342 are located on both sides of the spring column 343, and the spring column 343 is away from the fixing plate 344. One end of 41 is fixedly installed on the top component 344, and the end of the telescopic shaft 342 away from the fixed plate 341 is fixedly installed on the top component 344. Slide rails 33 are fixedly installed on both sides of the inner wall 35. The upper locking member 3442 has sliding grooves 3443 on both sides, which are adapted to the slide rails 33. The upper locking member 3442 moves at its upper limit on the slide rails 33 via the sliding grooves 3443. The mounting component 1 includes a mounting plate 11 fixedly installed below the locking component 3. Multiple mounting holes 12 are provided on the mounting plate 11, which, in conjunction with bolts, are used to fix the mounting plate 11 to the wall. A connecting line 21 is fixedly installed at the end of the outer cylinder 23 away from the thread 22. The connecting line 21 is used for electrical connection between the switch body 2 and external electronic devices. An installation cylinder 24 is fixedly installed at the end of the outer cylinder 23 away from the connecting line 21. An installation head 25 is detachably installed on the installation cylinder 24. A threaded groove is opened on the outer side of the installation head 25 and a threaded groove is opened on the inner side of the installation cylinder 24. The installation head 25 is threadedly connected to the installation cylinder 24. A sensing head 26 is fixedly installed at the end of the installation head 25 away from the installation cylinder 24. The ends of the lower locking member 31 and the upper locking member 3442 that contact the switch body 2 are both curved plates.

[0025] Since the lower locking member 31 and the upper locking member 3442 are both curved plates that contact the switch body 2, and the lower locking member 31 and the upper locking member 3442 can fit completely against the switch body 2 when they contact the outside of the switch body 2, and since the lower thread 32 and the upper thread 3441 are both compatible with the thread 22 on the outer cylinder 23, when the switch body 2 is located inside the locking assembly 3, the user only needs to slightly rotate the switch body 2 to firmly fix the easily detachable photoelectric switch between the lower locking member 31 and the upper locking member 3442.

[0026] Since the size of the slide rail 33 is the same as the size of the slide groove 3443, when the spring column 343 moves downward with the upper locking member 3442, the upper locking member 3442 will move in a limited position on the slide rail 33 on the outer wall 35 through the slide groove 3443, so that the lower locking member 31 and the upper locking member 3442 can be aligned at all times and apply a downward squeezing force to the switch body 2.

[0027] Since the spring column 343 is fixedly installed between the fixed plate 341 and the top component 344, when the user moves the top component 344 upward, the spring column 343 will retract. At this time, the gap between the lower locking member 31 and the upper locking member 3442 will increase, and the user can place the switch body 2 between the lower locking member 31 and the upper locking member 3442. Then, the user only needs to release his hand to squeeze the switch body 2 by the rebound force of the spring column 343.

[0028] Once the switch body 2 is installed, the user can fix the easily disassembled photoelectric switch onto a wall or other panel by using bolts and mounting holes 12, thus improving the ease of installation of the easily disassembled photoelectric switch.

[0029] The switch body 2 is based on the photoelectric effect to detect and control objects. When light from a light source shines on a photosensitive element, the photosensitive element generates an electrical signal. The photoelectric switch utilizes this principle, combining a light source and a photosensitive element to achieve functions such as object proximity, distance measurement, and counting. The photoelectric switch consists of three parts: a transmitter, a receiver, and a detection circuit. The transmitter emits a light beam towards the target, typically from a light-emitting diode or laser diode. The sensing head 26 serves as the receiver. Since the mounting cylinder 24 and the mounting head 25 are threadedly connected, the user can easily detach the mounting head 25 from the mounting cylinder 24 by simply rotating it.

[0030] The working principle of this utility model is explained below: Unless otherwise specified, all the internal mechanical structures of the easily disassembled photoelectric switch are fixed by threads. In order to make the technical features more intuitive to observe, the bolt connections are appropriately hidden in the figure. Before using the easily disassembled photoelectric switch, when the user needs to install the switch body 2, the user only needs to grasp the protruding plates at both ends of the top component 344 and lift it upwards, causing the spring column 343 to retract. At this time, the user can place the switch body 2 between the lower locking member 31 and the upper locking member 3442. Then, by releasing the user, the spring column 343 will spring back, thus fixing the switch body 2 between the lower locking member 31 and the upper locking member 3442. At this time, the user needs to rotate the switch body 2 so that the thread 22 on the switch body 2 is threadedly connected with the upper thread 3441 on the upper locking member 3442 and the lower thread 32 on the lower locking member 31. At this time, the switch body 2 can be firmly fixed between the lower locking member 31 and the upper locking member 3442. Through the cooperation of the above structure, the user can more easily disassemble and assemble the switch body without adding any structure to the switch body 2, thus improving the practicality of the easily disassembled photoelectric switch.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
