Description

Technical Field

[0001] This utility model relates to the field of switch and electrical appliance technology, specifically to a novel wall switch. Background Technology

[0002] In existing technologies, the switch panel of a wall switch is usually rotatably connected to the panel frame, which in turn needs to be fixed to the switch box with screws and other connectors. The overall assembly needs to be completed in multiple steps, including assembling the switch panel and the panel frame, and then locking the panel frame to the switch box. This not only involves a large number of parts, but also makes the processing and assembly process cumbersome, which is not conducive to cost reduction and efficiency improvement on the production side, and also brings inconvenience to terminal installation and maintenance. Utility Model Content

[0003] In view of this, the present invention provides a novel wall switch.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A novel wall switch includes a switch box, a switch panel, and a panel frame. The panel frame is mounted on the switch box, and the switch box protrudes toward the switch panel to form a panel connecting arm. The panel connecting arm passes through the panel frame and is rotatably connected to the switch panel. The panel connecting arm and the panel frame are snap-fitted together.

[0006] Preferably, a panel rotating groove is formed on the panel connecting arm, and a panel rotating end is provided on the side end face of the switch panel near the switch box corresponding to the panel rotating groove. The panel rotating end extends into the panel rotating groove and is rotatably connected to the panel connecting arm.

[0007] Preferably, the panel rotation groove has a guide groove, a transition groove, and a rotating groove. The guide groove has an inverted trapezoidal cross-sectional shape. The transition groove is located between the guide groove and the rotating groove. The maximum width of the guide groove is greater than the width of the transition groove, and the width of the transition groove is less than the diameter of the rotating groove. The rotating end of the panel first enters the guide groove and then is engaged with the rotating groove through the transition groove to complete the assembly.

[0008] Preferably, deformation grooves are formed on both sides of the panel connecting arm near the panel rotating groove. The deformation grooves divide the panel connecting arm so that the position of the panel connecting arm near the panel rotating groove forms a connecting segment. The panel rotating groove is formed on the connecting segment. After the rotating end of the panel extends into the panel rotating groove, the two sides of the connecting segment undergo elastic deformation in the direction of the corresponding deformation groove.

[0009] Preferably, the panel connecting arm has a snap-fit ​​groove, the panel frame has a connecting hole, the panel connecting arm passes through the connecting hole and is rotatably connected to the switch panel, and the wall of the connecting hole protrudes to form a snap-fit ​​end corresponding to the snap-fit ​​groove, the snap-fit ​​end extends into the snap-fit ​​groove and is snap-fit ​​connected to the panel connecting arm.

[0010] Preferably, the panel frame also has mounting holes, and the wall of the mounting holes extends partially toward the switch box to form a limiting part.

[0011] Preferably, the panel frame has a reinforcing connecting part and a main body part. The reinforcing connecting part is located at the center of the main body part. A connecting groove is formed on the reinforcing connecting part. The panel connecting arm passes through the corresponding connecting groove and is rotatably connected to the switch panel. The reinforcing connecting part protrudes on both sides near the main body part to form reinforcing blocks that are in contact with the main body part.

[0012] The beneficial effects of this utility model are as follows: By directly protruding a panel connecting arm onto the switch box, the assembly of the switch box, panel frame, and switch panel can be achieved without the need for additional independent connecting fasteners. This simplifies the overall component structure of the switch, reduces the processing and assembly steps, and eliminates the need for screw fastening through the snap-fit ​​connection between the panel connecting arm and the panel frame, making the assembly of the entire switch more convenient. The snap-fit ​​connection also ensures the stability of the connection between the panel frame and the switch box, preventing loosening and detachment, effectively improving the structural reliability of the assembled wall switch. Compared to the existing technology where the switch panel and panel frame are rotated together, this design places the rotating connection between the switch box and the switch panel, distributing the connection structure originally concentrated at the panel frame. This avoids overly complex local structures in the panel frame, reduces the processing difficulty of the panel frame, and allows for more even stress distribution among the components, further optimizing the overall structural stability of the wall switch and extending its service life.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] This utility model provides the following technical solution:

[0022] As attached Figure 1-5 As shown, this utility model discloses a novel wall switch, including a switch box 1, a switch panel 2, and a panel frame 3. The panel frame 3 is disposed on the switch box 1, and the switch box 1 protrudes towards the switch panel 2 to form a panel connecting arm 4. The panel connecting arm 4 passes through the panel frame 3 and is rotatably connected to the switch panel 2. The panel connecting arm 4 and the panel frame 3 are connected by a snap-fit ​​connection. Specifically, in this design, by directly protruding the panel connecting arm 4 on the switch box 1, the assembly of the switch box 1, panel frame 3, and switch panel 2 can be achieved without the need for additional independent connecting fasteners. This simplifies the overall component structure of the switch, reduces the processing and assembly steps of the components, and eliminates the need for screw fastening through the snap-fit ​​connection between the panel connecting arm 4 and the panel frame 3, making the assembly of the entire switch more convenient. At the same time, the snap-fit ​​connection structure also ensures the stability of the connection between the panel frame 3 and the switch box 1, preventing loosening and detachment, effectively improving the structural reliability of the assembled novel wall switch. Compared to the existing technology where the switch panel 2 and the panel frame 3 are rotatably connected, this design sets the rotatable connection structure between the switch box 1 and the switch panel 2, dispersing the connection structure that was originally concentrated at the panel frame 3. This avoids the local structure of the panel frame 3 becoming too complex, reduces the processing difficulty of the panel frame 3, and also allows the force between each component to be more even, further optimizing the overall structural stability of the wall switch and extending the service life of the switch.

[0023] Furthermore, a panel rotating groove 5 is formed on the panel connecting arm 4, and a panel rotating end 6 is provided on the side end face of the switch panel 2 near the switch box 1 corresponding to the panel rotating groove 5. The panel rotating end 6 extends into the panel rotating groove 5 and is rotatably connected to the panel connecting arm 4. Specifically, in this embodiment, the panel rotating end 6 is set on the switch panel 2 instead of the panel connecting arm 4, and the panel connecting arm 4 is provided with a corresponding and suitable panel rotating groove 5. Compared with the prior art where the rotating groove structure is usually set on the switch panel 2, the dimensional accuracy requirements of the rotating structure can be transferred to the panel connecting arm 4 of the switch box 1, reducing the processing accuracy requirements of the switch panel 2. As a load-bearing support component, the switch box 1 itself has a higher redundancy in processing accuracy, making it easier to control the finished product qualification rate, reduce the scrap rate in the production process, and control the overall production cost. At the same time, this rotating fit structure is very simple to assemble; simply align the panel rotating end 6 with the panel rotating groove 5 and insert it to complete the pre-installation of the rotating structure, further improving the overall assembly efficiency.

[0024] Furthermore, the panel rotating groove 5 has a guide groove 7, a transition groove 8, and a rotating groove 9. The guide groove 7 has an inverted trapezoidal cross-sectional shape. The transition groove 8 is located between the guide groove 7 and the rotating groove 9. The maximum width of the guide groove 7 is greater than the width of the transition groove 8, and the width of the transition groove 8 is less than the diameter of the rotating groove 9. The rotating end 6 of the panel first enters the guide groove 7 and then is engaged with the rotating groove 9 through the transition groove 8 to complete the assembly. Specifically, in this embodiment, the inverted trapezoidal guide groove 7 has a larger opening, which facilitates the quick alignment and insertion of the rotating end 6 of the panel. Preliminary insertion can be completed without precise alignment, further reducing the alignment difficulty of the assembly. After the rotating end 6 of the panel slides into the guide groove 7, it passes through the narrower transition groove 8. At this time, the transition groove 8 guides and retracts the rotating end 6 of the panel, allowing it to smoothly enter the larger diameter rotating groove 9. After entering the rotating groove 9, the narrower transition groove 8 limits the rotating end 6 of the panel, preventing it from easily coming out of the rotating groove 9 and ensuring the stability of the rotating connection. At the same time, the rotating end 6 of the panel can rotate smoothly within the circular rotating groove 9 without any jamming or sticking. This simplifies the assembly process and ensures the reliability of the rotating structure.

[0025] Furthermore, deformation grooves 10 are formed on both sides of the panel connecting arm 4 near the panel rotating groove 5. The deformation grooves 10 divide the panel connecting arm 4 so that the position of the panel connecting arm 4 near the panel rotating groove 5 forms a connecting section 11. The panel rotating groove 5 is formed on the connecting section 11. After the panel rotating end 6 extends into the panel rotating groove 5, the two sides of the connecting section 11 undergo elastic deformation in the direction of the corresponding deformation groove 10. Specifically, in this embodiment, after the deformation groove 10 is opened, the connecting section 11 has a space for elastic deformation. When the panel rotating end 6 is squeezed from the transition groove 8 into the rotating groove 9, the two sides of the connecting section 11 can open slightly along the direction of the deformation groove 10 to avoid it, so that the larger panel rotating end 6 can pass smoothly through the transition groove 8 and enter the rotating groove 9. After the panel rotating end 6 is fully inserted, the connecting section 11 quickly resets itself due to its own elasticity. No additional operation is required to complete the snap-fit, which will not affect the normal rotation of the panel rotating end 6 in the rotating groove 9. This further reduces the assembly difficulty. At the same time, the elastic deformation design can also allow the connecting section 11 to maintain a certain squeezing force on the panel rotating end 6, reduce the gap of rotational fit, and avoid the problem of shaking and loosening of the switch panel 2 after long-term use, further improving the structural stability.

[0026] Furthermore, a latching groove 12 is provided on the panel connecting arm 4, and a connecting hole 13 is provided on the panel frame 3. The panel connecting arm 4 passes through the connecting hole 13 and is rotatably connected to the switch panel 2. A latching end 14 protrudes from the wall of the connecting hole 13 corresponding to the latching groove 12, and the latching end 14 extends into the latching groove 12 and latches with the panel connecting arm 4. Specifically, in this embodiment, after the panel connecting arm 4 passes through the connecting hole 13 of the panel frame 3, the latching end 14 directly latches into the corresponding latching groove 12 to complete the fixation between the panel frame 3 and the switch box 1. No additional fasteners such as screws are needed. During assembly, only pressing the panel frame 3 is required to complete the latching lock. The operation threshold is low, and ordinary users can complete the installation themselves without the need for professional construction personnel. At the same time, the structural fitting precision requirements of the latching connection are low, and problems such as stripped screws and incomplete locking will not occur. The assembly fault tolerance rate is higher, which can effectively improve the production efficiency of batch assembly. It is also convenient to disassemble the panel frame 3 when repairing switch failures, without causing irreversible structural damage to the switch components.

[0027] Furthermore, the panel frame 3 also has mounting holes 15, and a portion of the wall of the mounting hole 15 extends toward the switch box 1 to form a limiting part 16. Specifically, in this embodiment, the limiting part can axially limit the fixing screws that extend into the mounting hole. During the process of fixing the entire switch to the preset wall box, the limiting part can prevent the screws from tilting or shifting after installation, ensuring that the entire switch is more upright and securely fixed on the wall box.

[0028] Furthermore, the panel frame 3 has a reinforcing connecting part 17 and a main body part 18. The reinforcing connecting part 17 is located at the center of the main body part 18, and a connecting groove 19 is formed on the reinforcing connecting part 17. The panel connecting arm 4 passes through the corresponding connecting groove 20 and is rotatably connected to the switch panel 2. The reinforcing connecting part 17 protrudes on both sides near the main body part 18 to form reinforcing blocks 21 that connect with the main body part 18. Specifically, in this embodiment, the core connecting structure of the switch box is concentrated on the central reinforcing connecting part. Combined with the reinforcing blocks protruding on both sides, the structural strength of the central area of ​​the panel frame can be effectively improved. This avoids the problem of deformation and cracking in the central area of ​​the panel frame after long-term repeated stress caused by the rotation of the switch panel, further extending the service life of the panel frame. At the same time, the centralized reinforcing structure does not require thickening of the entire panel frame. While ensuring structural strength, the overall material usage of the panel frame is controlled, and no additional production costs are increased.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
