DETAILED DESCRIPTION

[0026] Based on this, in order to improve the problem that the key panel of the switch in the related art is easy to be mistaken, the embodiments of the present application provide the following solutions.

[0027] The following will be described in detail. Figures 1 to 8 The utility model is further described in detail.

[0028] The embodiment discloses a kind of anti-misoperation wall switch: a kind of anti-misoperation wall switch includes shell 1, three installation slots 11 are opened in shell 1, a group of switch mechanisms are arranged in installation slot 11 inside, and switch mechanism includes press shell 21, control assembly, locking assembly and recovery assembly, rotating shaft 212 is fixedly arranged on the side of press shell 21, rotating shaft 212 is rotatably connected with shell 1, two first through holes 211 are symmetrically opened in the top of press shell 21, locking assembly and recovery assembly are symmetrically provided with two groups, locking assembly includes button 41, adjusting block 42 and latch 43, button 41 is slidably connected inside first through hole 211, the section of adjusting block 42 is upper narrow lower wide isosceles trapezoidal, adjusting block 42 is fixedly connected at the bottom of button 41 on the top, sliding groove 421 is opened in adjusting block 42, U-shaped groove 213 is opened in the side of press shell 21, latch 43 is a pipe structure with one end closed, the closed end of latch 43 is abutted with the side of adjusting block 42 and slidably connected inside sliding groove 421, plug groove 432 and arc surface are opened in the other end of latch 43 and slidably connected with press shell 21 through U-shaped groove 213, the end of latch 43 away from adjusting block 42 is abutted with the part of shell 1 at the edge of installation slot 11 through arc surface, first spring 431 is arranged in latch 43, one end of first spring 431 is abutted with press shell 21, the other end of first spring 431 is abutted with latch 43 inside, recovery assembly is used to make button 41 and adjusting block 42 descend and then automatically return to original position, control assembly is used to switch the power-on state of switch when press shell rotates.

[0029] Recovery assembly includes two spring columns 51 and second spring 52, spring column 51 is fixedly connected on the inner surface of press shell 21 and the bottom of adjusting block 42 respectively, second spring 52 is sleeved on two spring columns 51 at two ends, one end of second spring 52 is abutted with press shell 21, the other end of second spring 52 is abutted with the bottom of adjusting block 42.

[0030] From the above, the wall switch anti-misoperation provided by the embodiment of the application can prevent the switch from being misoperated. When the switch is at rest, the third spring 342 continuously applies upward pressure to the adjusting block 42, so that the button 41 is tightly attached to the pressing shell 1, the first spring 431 applies pressure to the plug 43 to make it close to the adjusting block 42, and one end of the plug 43 is tightly pressed against the inclined surface of the adjusting block 42. At this time, the end of the pressing shell 21 that is away from the adjusting block 42 is in abutment with the arc surface and the part of the shell 1 located at the edge of the mounting groove 11. Since the third spring 342 keeps the position of the adjusting block 42 unchanged, the adjusting block 42 prevents the plug 43 from moving towards the inside of the pressing shell 21, so that the end of the pressing shell 21 cannot be pressed back into the mounting groove 11, and the pressing shell 21 is locked. When it is needed to turn on or off a switch, the button 41 located at the end of the pressing shell 21 that is away from the adjusting block 42 is pressed, and the button 41 drives the adjusting block 42 to move downwards. Since the adjusting block 42 has the cross-sectional shape of an isosceles trapezoid with the upper part being narrow and the lower part being wide, when the adjusting block 42 moves downwards, the end of the plug 43 in contact with the adjusting block 42 slides in the sliding groove 421, and the plug 43 slides towards the adjusting block 42 under the action of the first spring 431. The part of the plug 43 located outside the pressing shell 21 is gradually retracted into the pressing shell 21, so as to be separated from the shell 1 and release the locking of the pressing shell 21. Then, the button 41 is continuously pressed, and the button 41 applies pressure to the end of the pressing shell 21 that is away from the adjusting block 42 through the adjusting block 42 and the third spring 342, so that the end of the pressing shell 21 rotates around the rotating shaft 212. The end of the pressing shell 21 gradually enters the inside of the mounting groove 11 until it cannot move any more. The pressing shell 21 will switch the power-on state of the switch through the control assembly in the rotating process. At this time, the end of the pressing shell 21 that is retracted moves to the outside of the mounting groove 11, the third spring 342 located at the end applies upward pressure to the adjusting block 42 to make it move upwards, and the adjusting block 42 moves upwards to push the plug 43 to move towards the outside of the pressing shell 21 through the inclined surface of the adjusting block 42 and finally lock the pressing shell 21, so as to complete the turning on or off of the switch. Since only the button 41 is pressed and a certain pressure is continuously applied to make the pressing shell 21 rotate, if the user misoperates the pressing shell 21, the misoperated pressing shell 21 cannot be rotated, so as to avoid changing the on-off state of the misoperated pressing shell 21 and prevent the switch from being misoperated.

[0031] In some embodiments, please refer to Figures 4 to 7The control assembly comprises a first connecting plate 31, a second connecting plate 32, a V-shaped connecting plate 33 and a transmission assembly. The first connecting plate 31 and the second connecting plate 32 are fixedly arranged on the inner surface of the shell 1. The bottom of the first connecting plate 31 and the second connecting plate 32 is further provided with a wiring assembly for connecting with external lines. The bending part of the V-shaped connecting plate 33 is hingedly connected to the top of the first connecting plate 31. One side of the V-shaped connecting plate 33 abuts against the first connecting plate 31 and the second connecting plate 32. The transmission assembly is used to convert the power generated when the pressing shell 21 rotates into the power for rotating the V-shaped connecting plate 33.

[0032] The transmission assembly comprises a spring barrel 341, a third spring 342 and a transmission pin 343. The bottom of the pressing shell 21 is provided with a second through hole 214. One end of the spring barrel 341 is fixedly connected to the inner surface of the shell 1. The other end of the spring barrel 341 passes through the second through hole 214. One end of the transmission pin 343 is slidably connected to the inside of the spring barrel 341. The other end of the transmission pin 343 is semicircular and abuts against one side of the V-shaped connecting plate 33. The third spring 342 is arranged in the spring barrel 341 and located between the pressing shell 21 and the transmission pin 343.

[0033] In this way, when installing the switch, the worker can electrically connect the live wire and the neutral wire of the electrical appliance with the first connecting plate 31 and the second connecting plate 32 through the two sets of wiring assemblies respectively. In the initial state, one side of the V-shaped connecting plate 33 is connected with the first connecting plate 31 and the second connecting plate 32. At this time, the circuit is in the on state. When it is needed to disconnect the circuit, the pressing shell 21 is rotated to another position according to the above steps. During the rotation of the pressing shell 21 around the rotating shaft 212, the third spring 342 and the transmission pin 343 are driven to rotate by the spring barrel 341. The semicircular end of the transmission pin 343 slides on the V-shaped connecting plate 33. The transmission pin 343 can slide in the spring barrel 341 to adapt to the change of the straight-line distance from the opening of the spring barrel 341 to the V-shaped connecting plate 33. The third spring 342 makes the semicircular end of the transmission pin 343 continuously adhere to the V-shaped connecting plate 33. After the transmission pin 343 passes through the bending part of the V-shaped connecting plate 33, the transmission pin 343 applies pressure to the other side of the V-shaped connecting plate 33. The rotation of the V-shaped connecting plate 33 makes the side in contact with the second connecting plate 32 rise, so that the connection between the first connecting plate 31 and the second connecting plate 32 is disconnected. At this time, the circuit is in the off state. After the pressing shell 21 is rotated to another position and locked, the transmission pin 343 is rotated to a position symmetrical to the initial position, so as to complete the change of the on-off state of the switch.

[0034] Optionally, in some embodiments, please refer to Figures 2 to 4The wiring assembly comprises a supporting cylinder 61 and a wire pressing bolt 62, the bottom of the supporting cylinder 61 is closed, the top of the supporting cylinder 61 penetrates through the bottom of the shell 1 and is fixedly connected to the bottom of the first connecting plate 31, one end of the wire pressing bolt 62 penetrates through the bottom of the supporting cylinder 61 and is threadedly connected with the supporting cylinder 61, and two opposite sides of the supporting cylinder 61 are provided with wire penetrating holes 611.

[0035] In this way, when connecting the live wire with the first connecting plate 31, the worker can pass the exposed end of the live wire through the wire penetrating hole 611 and place it between the wire pressing bolt 62 and the first connecting plate 31, then screw the wire pressing bolt 62, the wire pressing bolt 62 moves to the inside of the supporting cylinder 61 and presses the core of the live wire on the first connecting plate 31, thereby completing the connection of the live wire with the first connecting plate 31, and the same operation can be performed on the zero line and the second connecting plate 32.

[0036] Optionally, referring to Figure 1 The top of each of the buttons 41 is embedded with a fluorescent plate 7.

[0037] In this way, the fluorescent plate 7 can emit fluorescence at night and indicate the positions of the switch and the buttons 41 to the user, so that the user can use the switch in the absence of illumination.

[0038] The above only describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
