Description

Technical Field

[0001] This utility model relates to the field of time delay switch technology, specifically a time delay switch for building lighting. Background Technology

[0002] The time delay switch is a new type of automatic time delay electronic switch developed to save power resources. It is energy-saving and convenient, and is mainly used in stairwells, bathrooms and other places. In the field of electrical installation, the installation of existing time delay switches generally adopts the traditional mechanical fixing structure, that is, the switch body is fastened to the inside of the wall box by matching bolts to ensure the structural stability during use.

[0003] When a time-delay switch needs maintenance due to internal component failure or poor wiring contact, the operator must first use a screwdriver to loosen and remove the fixing bolts one by one, and then carefully separate the switch body from the wiring terminals inside the junction box before conducting circuit testing or switch repair work. After the maintenance is completed, the bolt holes of the switch body and the junction box must be aligned again and the bolts tightened to restore the installation state. This maintenance method, which relies on repeated disassembly and reassembly of bolts, not only makes the single maintenance operation process cumbersome and time-consuming, but also significantly slows down the overall maintenance progress and affects work efficiency, especially in the case of batch maintenance of buildings or emergency maintenance of power failures. Furthermore, frequent tightening of bolts can easily cause secondary problems such as stripped bolt threads and damage to the internal threads of the junction box. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a delay switch for building lighting to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a delay switch for building lighting, comprising a switch body, a snap-fit ​​frame on the back of the switch body, snap-fit ​​openings on the upper side and lower side of one side of the snap-fit ​​frame, mounting grooves on the top and bottom of the switch body, and a pressing block connected to the inner side of the mounting groove by a spring, and a hook fixed on the back of the pressing block, and a shell cover on the outer surface of the switch body.

[0006] Furthermore, a connector is provided in the middle of the back of the switch body, a wiring hole is provided on the back of the connector, and a wire clamping bolt extending into the wiring hole is passed through the top of the connector.

[0007] By adopting the above technical solution, the wire can be inserted through the wiring hole on the back of the connector, and then the wire clamping bolt that goes through the wiring hole at the top is tightened to secure the wire with the mechanical compression of the bolt.

[0008] Furthermore, the inner side of the snap-fit ​​frame is provided with a recessed hole.

[0009] By adopting the above technical solution, the recessed hole provides a suitable space for the bolt head of the fixing snap-fit ​​frame and the junction box, so that the bolt head can be completely recessed into the hole after tightening, avoiding the formation of a protrusion on the inside of the snap-fit ​​frame, eliminating the interference of the protruding bolt head on the snap-fit ​​process of the switch body, and ensuring that the switch body can be accurately aligned and tightly fitted to the snap-fit ​​frame.

[0010] Furthermore, the cover is detachably connected to the switch body, and the inner wall of the cover is provided with a rubber layer.

[0011] By adopting the above technical solution, the disassembly and assembly of the cover and the switch body allows the cover to be quickly removed without additional tools during maintenance. The rubber layer increases the tightness of the cover's fit with the switch body during installation, preventing the cover from loosening and falling off. It also isolates external dust and moisture from entering, further protecting the internal components of the switch body.

[0012] Furthermore, friction textures are fixed on both sides of the shell cover.

[0013] By adopting the above technical solution, the friction texture increases the friction between the hand and the cover, making it easier for workers to apply force when disassembling and assembling the cover, and avoiding inconvenience caused by hand slippage.

[0014] Furthermore, the switch body is adapted to the snap-fit ​​frame, one side of the snap hook is sloped, and the snap hook is adapted to the snap-fit ​​opening.

[0015] By adopting the above technical solution, the switch body and the snap-fit ​​frame are compatible, which allows the switch body and the snap-fit ​​frame to be installed tightly. The inclined guide effect of the snap hook allows the snap hook to slide into the slot automatically when the switch body is snapped in, without the need for deliberate alignment, which greatly reduces the assembly difficulty. At the same time, the compatibility design can also ensure that the snap-fit ​​is tight and does not loosen after snapping, and the snap hook can be smoothly disengaged when disassembling, further enhancing the practicality and stability of quick installation and disassembly.

[0016] Furthermore, a touch button is provided in the middle of the outer surface of the switch body.

[0017] By adopting the above technical solution, staff can trigger the switch's delay control function for the lamps by touching the touch button.

[0018] Furthermore, sliding grooves are provided on both sides of the mounting groove, and sliders are fixed on both sides of the pressing block, with the pressing block slidingly engaging with the sliding grooves via the sliders.

[0019] By adopting the above technical solution, the slider and the groove provide precise guidance for the movement of the pressing block, ensuring that the pressing block is stably displaced only along the direction of the groove when it is under force, and avoiding deviation and jamming.

[0020] In summary, the present invention has the following main advantages: This utility model features a pressing block, a spring, a hook, a latch, a locking frame, and a cover. During initial installation, the operator only needs to fix the locking frame to the junction box with bolts, then directly insert the switch body into the inside of the locking frame. The hook will automatically engage with the latch, quickly completing the installation and fixing of the switch body. The cover is then placed on the switch body. The subsequently installed cover not only effectively protects the pressing block from accidental activation or the intrusion of external dust and impurities, but also improves the overall neatness of the appearance. When maintenance is required, the operator does not need to use screwdrivers or other tools; they only need to remove the cover first, and then... When pressure is applied to the upper and lower sets of pressing blocks, the pressing blocks are displaced after overcoming the spring force, which can drive the hook to quickly disengage from the bayonet. Then, the switch body can be removed from the snap-fit ​​frame. The entire disassembly process is simple and quick, greatly simplifying the cumbersome steps of traditional bolt disassembly and assembly, effectively improving the efficiency of maintenance work. It is especially suitable for batch switch maintenance or emergency fault handling scenarios. At the same time, it can also avoid secondary problems such as bolt stripping and junction box thread damage caused by repeated tightening of bolts, reducing the difficulty and cost of subsequent maintenance, and taking into account installation stability, use safety and maintenance convenience.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] Example 1: A time-delay switch for building lighting, such as Figures 1-6 As shown, the switch body 1 includes a snap-fit ​​frame 3 on its back. Snap-fit ​​slots 10 are provided on the upper and lower sides of one side of the snap-fit ​​frame 3. Mounting grooves 7 are provided on the top and bottom of the switch body 1. A pressing block 8 is connected to the inner side of the mounting groove 7 via a spring 13, and a hook 9 is fixed to the back of the pressing block 8. A cover 2 is provided on the outer surface of the switch body 1. The cover 2 is detachably mounted from the switch body 1. A rubber layer 6 is provided on the inner wall of the cover 2. The detachable mounting allows the cover 2 to be quickly removed without additional tools during maintenance. The rubber layer 6 increases the tightness of the cover 2's fit with the switch body 1 during installation, preventing the cover 2 from loosening and falling off. It also isolates external dust and moisture, further protecting the internal components of the switch body 1. Friction textures 5 are fixed on both sides of the cover 2. These friction textures increase the friction between the hand and the cover 2, making it easier for workers to apply force when installing or removing the cover 2 and preventing slippage.

[0026] See Figure 2 and Figure 5 In the above embodiment, a connector 4 is provided in the middle of the back of the switch body 1. A wiring hole 16 is provided on the back of the connector 4. A wire clamping bolt 17 extending into the wiring hole 16 is passed through the top of the connector 4. The wire can be inserted through the wiring hole 16 on the back of the connector 4. The wire is then firmly fixed by tightening the wire clamping bolt 17 that extends into the wiring hole 16.

[0027] See Figures 2-3 In the above embodiment, the inner side of the snap-fit ​​frame 3 is provided with a recessed hole 15. The recessed hole 15 provides a suitable space for the bolt head of the snap-fit ​​frame 3 and the dark box to be fitted and accommodated, so that the bolt head can be completely recessed into the hole after tightening, avoiding the formation of a protrusion on the inner side of the snap-fit ​​frame 3, eliminating the interference of the protruding bolt head on the snap-fit ​​process of the switch body 1, and ensuring that the switch body 1 can be accurately aligned and tightly fitted to the snap-fit ​​frame 3.

[0028] See Figure 2 , Figure 3 , Figure 5 and Figure 6In the above embodiment, the switch body 1 is adapted to the snap-fit ​​frame 3, one side of the snap hook 9 is sloping, and the snap hook 9 is adapted to the snap-fit ​​slot 10. The adaptation of the switch body 1 and the snap-fit ​​frame 3 enables the switch body 1 and the snap-fit ​​frame 3 to be installed tightly. With the guiding effect of the sloping surface of the snap hook 9, the snap hook 9 can automatically slide into the snap-fit ​​slot 10 when the switch body 1 is snapped in, without the need for deliberate alignment, which greatly reduces the assembly difficulty. At the same time, the adaptation design can also ensure that the snap-fit ​​is tight and does not loosen after snapping, and the snap hook 9 can be smoothly disengaged when disassembling, further enhancing the practicality and stability of quick installation and disassembly.

[0029] See Figure 1 and Figure 5 In the above embodiment, a touch button 14 is provided in the middle of the outer surface of the switch body 1. The touch button 14 is electrically connected to the internal circuit of the terminal 4. The operator triggers the switch to control the lamp delay function by touching the touch button 14. (Touch delay switch is a mature existing technology. The technical solution of this application does not involve its internal working principle. Its circuit and working principle will not be described in detail here.)

[0030] Example 2: To make the displacement of the pressing block more stable and less prone to deviation, Example 2 is an improvement on Example 1. (See attached document.) Figure 2 , Figure 5 and Figure 6 The mounting groove 7 has sliding grooves 11 on both sides, and the pressing block 8 has sliders 12 fixed on both sides. The pressing block 8 slides with the sliding grooves 11 through the sliders 12. The sliders 12 and the sliding grooves 11 provide precise guidance for the movement of the pressing block 8, ensuring that the pressing block 8 is stably displaced only along the direction of the sliding grooves 11 when it is under force, and avoiding deviation and jamming.

[0031] The implementation principle of this utility model is as follows: During initial installation, the operator only needs to fix the snap-fit ​​frame 3 to the junction box with bolts, and then fix the power-carrying wire to the connector 4. Then, the operator directly snaps the switch body 1 into the inside of the snap-fit ​​frame 3. At this time, the snap hook 9 will automatically snap into the slot 10, quickly completing the installation and fixing of the switch body 1. Then, the cover 2 is put on the switch body 1. The subsequently installed cover 2 can not only effectively protect the pressing block 8, preventing accidental contact or the intrusion of external dust and impurities; when the extension switch needs maintenance, the operator only needs to remove the cover 2 first, and then apply pressure to the upper and lower sets of pressing blocks 8 at the same time. After the pressing block 8 is subjected to force, it overcomes the elastic force of the spring 13 and moves, which can drive the snap hook 9 to quickly disengage from the slot 10. Then, the switch body 1 can be removed from the snap-fit ​​frame 3 for maintenance.
