[0002] A wall switch is an electrical switch installed on a wall for use. It is used to connect and disconnect circuits to control lighting. The connection and disconnection of the circuit is achieved by a button on the switch. For example, in the patent with the announcement number "CN219842919U" and the name of "A Smart Wall Switch", the bracket is installed together with the back shell, and the power supply PCBA is installed in the back shell along the mounting rod, so that the clamping block is clamped in the groove, the wire is extended into the wire feed groove along the axial direction of the support tube, and the bolt is tightened so that the end of the bolt presses the end of the wire against the bottom wall of the wire feed groove, the top clamping ring is rotated so that the end of the top clamping ring coincides with the end of the bottom clamping ring, and the top clamping ring and the bottom clamping ring are tightly clamped with the wire through the fixing piece, thereby further tightening the wire, reducing the tendency of the wire to separate from the bolt, and making the wire and the bolt better connected. Then the bracket and the back shell are installed in the dark box. However, the above structure still has the following problems in actual use:

[0003] In the above structure, the bracket and the rear shell are fixed with bolts. Usually, during maintenance, it is only necessary to remove the bolts connecting the bracket and the rear shell, and then take down the bracket for disassembly and maintenance. Usually, maintenance personnel need to use tools to assist in disassembly. However, this disassembly method is not only cumbersome, but also time-consuming and labor-intensive, which is not conducive to maintenance by maintenance personnel.

[0004] Therefore, we proposed a quick-release assembled wall switch that can solve the above problems well. Utility Model Content

[0005] The purpose of the present utility model is to provide a quick-release assembled wall switch to solve the problem raised in the above-mentioned background technology that maintenance personnel are usually required to use tools to assist in disassembly in the current market. However, such disassembly method is not only cumbersome, but also time-consuming and labor-intensive, which is not conducive to maintenance personnel's inspection.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a quick-release assembled wall switch, comprising a housing and a front cover embedded in the upper end surface of the housing for fixing a switch button;

[0007] It also includes: a limit block is fixed on the outer side of the front cover, and the limit block fits with the shell. At the same time, an insertion rod is fixed on the lower end surface of the front cover, and a disassembly and assembly mechanism is provided at the lower end of the insertion rod, and the disassembly and assembly effect is achieved by sliding the pressure rod.

[0008] Preferably, the disassembly and assembly mechanism includes a fixing plate and a pressure rod, the fixing plate is fixed to the inner wall of the shell, and the pressure rod is arranged inside the insertion rod, and the upper end of the pressure rod extends out of the front cover.

[0009] Preferably, four groups of the insertion rods are provided, and all four groups of insertion rods are plugged into the fixing plates.

[0010] Preferably, the pressure rod is elastically slidably connected to the insertion rod via a return spring, and both ends of the return spring are fixed to the pressure rod and the insertion rod respectively.

[0011] Preferably, the lower end of the pressure rod is rotatably connected to one end of the connecting rod, and the other end of the connecting rod is rotatably connected to the inner side of the block. At the same time, the outer end of the block extends out the insertion rod and forms a sliding connection with the insertion rod, and the lower side surface of the outer end of the block is arranged in an inclined structure.

[0012] Preferably, a protective cover is provided on the upper end surface of the shell, and the protective cover is rotatably connected to the shell through a connecting block.

[0013] Preferably, a torsion spring is provided on the outer side of the connecting block, and when the protective cover is parallel, the torsion spring is in a force storage state, and a clip plate is fixed to the front lower end face of the protective cover, and the clip plate is clipped with the outer shell, and the clip plate is made of elastic rebound recovery plastic.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the quick-disassembly assembled wall switch is not only convenient for maintenance personnel to inspect its internal structure, but also the disassembly process is simple and convenient, and can be disassembled without the use of tools, thereby greatly improving the maintenance efficiency of workers. In addition, the protective cover is provided to protect the front cover and the upper surface of the switch, thereby avoiding accidental touch, and also playing a role of dust and water resistance. The specific contents are as follows:

[0015] (1) By moving the connecting rod upward, the connecting rod drives the block connected to the other end to slide toward the inside of the plug rod, so that the block is no longer limited. At this time, the plug rod can be taken out of the fixed plate. At this time, the front cover can be taken off as a whole, which makes it easier for maintenance personnel to inspect the inside. The disassembly process is simple and convenient, and can be disassembled without the help of tools, thereby greatly improving the maintenance work efficiency of workers;

[0016] (2) The elastic force of the reset spring drives the pressure rod to reset downward, and at the same time, the pressure rod is reset and the block is reset together through the connecting rod, so that the block slides out of the insertion rod. At this time, the insertion rod can be limited so that the insertion rod cannot be pulled out of the fixing plate, thereby completing the installation and fixing of the front cover;

[0017] Furthermore, after the repair is completed, it is only necessary to place the front cover on the outer shell again, and the limit block can limit the front cover so that the front cover can fit well with the outer shell. At the same time, the front cover will also drive the insertion rod to be plugged into the fixing plate.

[0018] Furthermore, the lower end surface of the fixing plate is provided with an inclined structure, so that it can automatically slide into the insertion rod when it is subjected to force, so that the insertion rod can continue to be inserted into the fixing plate. When the insertion rod drives the card block to move completely below the fixing plate, the card block is no longer under pressure.

[0019] A protective cover is provided on the top of the shell, which protects the front cover and the switches on the upper surface to avoid accidental touch, and also plays a role in dust and water prevention. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1-6 , the utility model provides the following technical solutions:

[0029] Embodiment 1: In order to solve the problem in the prior art that maintenance personnel usually need to use tools to assist in disassembly, but such disassembly method is not only cumbersome, but also time-consuming and labor-intensive, and is not conducive to maintenance personnel's inspection, the following scheme is disclosed, including a shell 1 and a front cover 2 embedded in the upper end surface of the shell 1 for fixing the switch button; it also includes: a limiting block 3 is fixed on the outer side of the front cover 2, and the limiting block 3 fits with the shell 1, and at the same time, a plug rod 8 is fixed on the lower end surface of the front cover 2, and a disassembly mechanism is provided at the lower end of the plug rod 8, and the disassembly effect is achieved by sliding the pressure rod 10. The disassembly mechanism includes a fixing plate 9 and a pressure rod 10, the fixing plate 9 is fixed to the inner wall of the shell 1, and the pressure rod 10 is arranged inside the plug rod 8, and the upper end of the pressure rod 10 extends out of the front cover 2, and four groups of plug rods 8 are provided, and the four groups of plug rods 8 are all plugged into the fixing plate 9.

[0030] First, when the wall switch needs to be repaired and replaced, it is only necessary to pull the pressure rod 10 upward, and through the pressure rod 10 upward, the pressure rod 10 drives one end of the connecting rod 12 upward together, and through the connecting rod 12 upward, the connecting rod 12 drives the other end of the rotating connected block 13 to slide toward the inside of the plug rod 8, so that the block 13 is no longer limited. At this time, the plug rod 8 can be taken out from the fixing plate 9, and the front cover 2 can be taken down as a whole, which is convenient for maintenance personnel to inspect the interior. The disassembly process is simple and convenient, and can be disassembled without the assistance of tools, thereby greatly improving the work efficiency of workers' maintenance.

[0031] Example 2: A new technical solution is added on the basis of Example 1 to facilitate the installation and fixation of the front cover 2. For details, refer to Figure 4-Figure 6 The pressure rod 10 is elastically slidingly connected to the insertion rod 8 through the return spring 11, and the two ends of the return spring 11 are respectively fixed to the pressure rod 10 and the insertion rod 8. The lower end of the pressure rod 10 is rotatably connected to one end of the connecting rod 12, and the other end of the connecting rod 12 is rotatably connected to the inner side of the block 13. At the same time, the outer end of the block 13 extends out of the insertion rod 8 and forms a sliding connection with the insertion rod 8, and the lower side surface of the outer end of the block 13 is arranged in an inclined structure.

[0032] When the cam 13 is fully moved to the bottom of the fixing plate 9, the block 13 is no longer under pressure, and the elastic force of the return spring 11 can be used to drive the pressure rod 10 to return downward, thereby causing the pressure rod 10 to be reset and the block 13 to be reset together with the connecting rod 12, thereby causing the block 13 to slide out of the cam 8, and the cam 8 can be limited so that the cam 8 cannot be pulled out of the fixing plate 9, thereby completing the installation and fixation of the front cover 2.

[0033] Example 3: The existing wall switch has no protective effect, so it is easy to be affected by external forces during use, resulting in accidental touch. At the same time, dust and water are easily splashed onto the switch, thereby affecting the safety and life of the switch. Therefore, the following solution is disclosed to protect the front cover 2 and the upper surface of the switch, thereby avoiding accidental touch, and also playing a role in dust and water resistance. For details, refer to Figure 1-Figure 3 A protective cover 4 is provided on the upper end surface of the shell 1, and the protective cover 4 is rotatably connected to the shell 1 through a connecting block 6. A torsion spring 7 is sleeved on the outer side of the connecting block 6, and when the protective cover 4 is parallel, the torsion spring 7 is in a stored force state, and a clamping plate 5 is fixed to the lower end surface of the front side of the protective cover 4, and the clamping plate 5 is clamped with the shell 1, and the clamping plate 5 is made of elastic rebound recovery plastic.

[0034] At the same time, a protective cover 4 is provided above the shell 1. Through the setting of the protective cover 4, the front cover 2 and the switch on the upper surface are protected to avoid accidental touch, and it can also play a role in dust and water prevention. The protective cover 4 is rotatably connected to the shell 1 through the connecting block 6, and a torsion spring 7 is provided on the outside of the connecting block 6. Through the setting of the torsion spring 7, the torsion force of the torsion spring 7 can drive the protective cover 4 to rotate automatically, and then when the clamping plate 5 is released from the limit, the protective cover 4 can automatically pop open, which is convenient for the user to use.
