DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] As shown in Figures 1, 2 and 3, a panel switch includes: a base 1, a middle plate 3, a rotor 7 and a metal panel 11. The middle plate 3 is snap-connected to the base 1, and the middle plate 3 is riveted to the metal bracket 5. The material of the metal bracket 5 is preferably stainless steel, and can also be other metal materials. The outer frame of the metal bracket 5 is snap-connected to the decorative frame 6, the rotor 7 is snap-connected to the pressure plate 8, the pressure plate 8 is snap-connected to the middle plate 3, and the metal panel 11 is snap-connected to the right side of the metal bracket 5. The snap-on design is adopted between each component, and the assembly can be completed by pressing and buckling. The assembly is simple and convenient, and the structural stability is better. It should be noted that the base 1, the middle plate 3, the decorative frame 6, the pressure plate 8 and the rotor 7 are preferably made of plastic, which has the advantage of being light and has better anti-rust and anti-corrosion properties.

[0034] As shown in Figure 7, a metal contact 2 is installed inside the base 1, and the metal contact 2 is preferably made of copper. The metal contact 2 is arranged to be a seesaw structure, wherein a neutral wire fixing component, a ground wire fixing component and a live neutral wire fixing component are installed inside the base. The neutral wire fixing component, the ground wire fixing component and the live neutral wire fixing component are preferably made of copper. One end of the metal contact 2 is fixedly connected to the live wire fixing component, and the other end of the metal contact 2 is movably connected to the live neutral wire fixing component. The specific structure can be referred to the prior art and will not be repeated here.

[0035] As shown in FIG9 , a center hole is provided at the axis position of the rotor 7, one end of the ejector spring 9 is inserted into the center hole, the other end of the ejector spring 9 is connected to the ejector 10, and the ejector 10 is slidably connected to the metal contact 2. By moving one end of the rotor 7 up and down by the lever 21, the other end of the rotor 7 drives the ejector 10 to press different positions of the metal contact 2, thereby realizing the opening and closing of the panel switch control circuit.

[0036] Two cylindrical protrusions 13 are symmetrically arranged on both sides of the rotor 7 , and a fixing frame 12 is arranged on the right side of the pressure plate 8 . When the two cylindrical protrusions 13 are connected to the fixing frame 12 , it is ensured that the rotor 7 can freely rotate at a certain angle relative to the pressure plate 8 .

[0037] In addition, a limit extension plate is integrally provided on the rotor, which can limit the rotation angle of the rotor 7. When the lever 21 is moved up and down, the two ends of the limit extension plate will first contact the surface of the pressure plate 8. At this time, the rotor 7 will no longer continue to rotate, preventing the ejector pin 10 from detaching from the metal contact piece 2, thereby effectively ensuring the stable cooperation between the ejector pin 10 and the metal contact piece 2.

[0038] As shown in FIG10 , a lever 21 is sleeved on one end of the rotor 7. The lever 21 is inserted through the side of the middle plate 3 and has a certain movable space. One end of the rotor 7 is designed to be prismatic, wherein a docking groove is provided on the end face of one end of the lever 21. One end of the rotor 7 is connected by clamping through the docking groove, that is, the lever 21 is sleeved on one end of the rotor 7.

[0039] It should be noted that, according to actual application conditions, one of square, Y-shaped, wavy and straight shapes is selected as the shape of the lever 21. Among them, the square and straight-shaped levers 21 are suitable for moving up and down, while the Y-shaped and wavy levers 21 are suitable for pressing.

[0040] As shown in Figures 4 and 6, the metal bracket 5 is connected to the middle plate 3 by riveting, and the outer frame of the metal bracket 5 is snap-connected to the decorative frame 6. The metal panel 11 is snap-connected to the right side of the metal bracket 5, and the metal snap 22 can be fixed to the right side of the metal bracket 5 by riveting and spot welding. The metal snap 22 is symmetrically arranged on the inner side of the metal panel 11, wherein the side facing the metal bracket 5 is the inner side of the metal panel 11, and a plurality of snap holes 14 are symmetrically arranged on the side of the metal bracket 5, and the snap holes 14 penetrate the metal bracket 5. Through the corresponding cooperation between the metal snap 22 and the snap holes 14, the two ends of the metal snap 22 enter the snap holes 14 and are locked on the right side of the metal bracket 5.

[0041] Among them, the metal buckle 22 is C-shaped, and the C-shaped opening faces the metal bracket 5. The metal buckle 22 is preferably a C-shaped elastic steel sheet. The two ends of the metal buckle 22 are arranged in a wavy shape, that is, the inner sides of the two ends of the metal buckle 22 form limiting protrusions 23, and the outer sides of the two ends of the metal buckle 22 are groove-shaped. When the two ends of the metal buckle 22 are connected to the card hole 14, the two ends of the metal buckle 22 will gradually move away from each other, that is, the two ends of the metal buckle 22 will be stretched outward until the two ends of the metal buckle 22 enter the card hole 14, and then the metal buckle 22 returns to its initial state, and the two ends of the metal buckle 22 are close to each other, and the limiting protrusion 23 locks the metal buckle 22. The card hole 14 is connected by the limiting protrusion 23 to achieve a stable connection between the metal panel 11 and the metal bracket 5.

[0042] In addition, a plurality of first positioning holes are symmetrically arranged on the side of the metal bracket 5, and a plurality of second positioning holes are symmetrically arranged on the side of the middle plate. Each first positioning hole is coaxially matched with a second positioning hole. The first positioning hole and the second positioning hole are used to pass screws to fix the panel switch as a whole on the wall.

[0043] In one embodiment of the utility model, a grounding terminal 16 is riveted on the left side of the metal bracket 5, and the grounding terminal 16 is externally connected to a ground wire. The grounding terminal 16 on the metal bracket 5 is used to ground the panel switch to prevent leakage and protect the electrical safety of the entire metal panel 11. The metal bracket 5 ensures that the panel will not be deformed due to the unevenness of the wall, thereby maintaining the beauty and durability of the entire metal panel 11.

[0044] In one embodiment of the utility model, several groups of clamping frames 18 are symmetrically arranged on the left side of the middle plate 3, and several clamping protrusions 17 are symmetrically arranged on both sides of the base 1. The side surfaces of the clamping protrusions 17 are designed to be sloped, which facilitates the docking of the clamping protrusions 17 with the clamping frames 18. Each clamping protrusion 17 is connected to a corresponding clamping frame 18 to ensure that the four clamping corners of the base 1 are stably clamped on one side of the middle plate 3.

[0045] Specifically, when the lever 21 is pressed downward, the other end of the rotor 7 tilts upward, that is, the ejector pin 10 presses the upper part of the metal contact 2, the upper part of the seesaw contacts the other metal contact 2, and the panel switch is energized; when the lever 21 is pushed upward, the upper part of the seesaw contacts the other metal contact 2, and the panel switch is no longer energized.

[0046] As shown in Figures 5 and 8, two limiting holes 20 are symmetrically set on the left side of the middle plate 3, and two limiting pins 19 are symmetrically set on the right side of the pressure plate 8. Each limiting pin 19 is connected to a corresponding limiting hole 20 to ensure that the pressure plate 8 can be stably snap-connected to the middle plate 3, assisting the snap-connection between the middle plate 3 and the pressure plate 8, and making the assembly process smoother.

[0047] It should be noted that the limit pin 19 can be selected to be formed by a combination of two separate semi-cylindrical structures, and the overall diameter of the limit pin 19 is larger than the inner diameter of the limit hole 20, so as to ensure that after the limit pin 19 enters the limit hole 20, the limit pin 19 will have a certain external supporting force on the inner wall of the limit hole 20, forming a certain clamping effect, making it difficult for the two to separate.

[0048] Specifically, when the lever 21 is pressed downward, the other end of the rotor 7 tilts upward, that is, the ejector pin 10 presses the upper part of the metal contact 2, the upper part of the seesaw contacts the other metal contact 2, and the panel switch is energized; when the lever 21 is pushed upward, the upper part of the seesaw contacts the other metal contact 2, and the panel switch is no longer energized.

[0049] In one embodiment of the utility model, a through assembly hole 4 is provided in the middle portion of the middle plate 3, and a through hole 15 is opened in the middle portion of the metal panel 11. The through hole 15 and the assembly hole 4 are both adapted to the lever 21. When the lever 21 is moved back and forth, the movement of the rotor 7 is not affected. The rotor 7 is designed to be square. The square rotor 7 can be used for both the lever 21 switch and the button switch, and can fix the direction of the lever 21 and the button so that they will not be displaced during use.

[0050] Among them, the design of the overall switch panel in the utility model has achieved an overall thickness of 3.5mm, which is the thinnest design in the switch industry. When installed on the wall, it has an ultra-thin visual effect and avoids the possibility of human body bumping into the switch panel during use to the greatest extent.

[0051] When assembling the utility model, the metal contact piece 2 is placed in the base 1, the rotor 7 is rotatably connected with the pressure plate 8, the pressure plate 8 is snap-connected to the middle plate 3, one end of the rotor 7 passes through the assembly hole 4, the ejector pin 10 and the ejector spring 9 are placed in the center hole together, the pressure plate 8 and the base 1 are snap-connected, at this time, the snap-connecting frame 18 and the snap-connecting protrusion 17 are snap-connected with each other, the ejector pin 10 slides and contacts the metal contact piece 2, the outer frame of the metal bracket 5 is snap-connected to the decorative frame 6, wherein the middle plate 3 is connected to the metal bracket 5 by a riveting process, the metal panel 11 is connected to the metal bracket 5 by a metal snap 22, the lever 21 is sleeved and installed on the rotor 7, and the panel switch assembly is completed.

[0052] In summary, the various components in the utility model are designed with a snap-on design. Compared with the traditional screw locking structure, the structure is more solid, and there is no problem of screws loosening due to aging and rusting, causing leakage. This effectively solves the safety hazard of leakage of traditional switch panels after long-term use.

[0053] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0054] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the utility model.
