DETAILED DESCRIPTION

[0026] The present invention will be further described in detail below with reference to the accompanying drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper", "lower", "bottom" and "top" used in the following description refer to directions in the accompanying drawings, and the terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0027] The present invention discloses an anti-electric shock switch, such as Figure 1 and Figure 2 As shown, it includes a switch base 1, a paddle 2 and a protective cover 3. The switch base 1 can be electrically connected to the circuit of an external device in an operably manner. The top surface of the switch base 1 is convex, and a groove 11 is provided on the convex top surface of the switch base 1. A switch handle 12 that can control the circuit connection between the switch base 1 and the external device to be disconnected or closed is arranged on the inner side wall of the groove 11. One end of the paddle 2 can be inserted into the groove 11, and a clamping portion 21 is arranged on the end of the paddle 2 that can be inserted into the groove 11. The clamping portion 21 can be clamped on the switch handle 12 to drive the switch handle 12 to rotate to achieve typical disconnection or closure. The protective cover 3 is hinged on the side wall of the top surface of the switch base 1 by a hinge, and the protective cover 3 can be arranged on the top surface of the switch base 1.

[0028] When the switch needs to be turned on and off, the protective cover 3 is opened, the engaging portion 21 of the paddle 2 is inserted into the groove 11 and clamped on the switch handle 12, and the switch handle 12 is driven to rotate by swinging the paddle 2 to realize the disconnection or closing of the circuit connecting the switch seat 1 and the external device. After the paddle 2 is used, the paddle 2 is pulled out to prevent others from using it. After the paddle 2 is pulled out, the protective cover 3 is closed to protect the switch handle 12, thereby reducing the possibility of danger caused by the switch handle 12 being accidentally touched.

[0029] like Figure 1 and Figure 2As shown, the switch seat 1 is fixed with a first magnetic sheet 14 on the outer wall near the top surface, and the protective cover 3 is fixed with a second magnetic sheet 32 ​​on the outer wall near the bottom surface that matches the position of the first magnetic sheet 14. The top surface of the first magnetic sheet 14 can contact the bottom surface of the second magnetic sheet 32, and the end surfaces of the first magnetic sheet 14 and the second magnetic sheet 32 ​​that are in contact with each other have opposite magnetic properties.

[0030] When the protective cover 3 is placed on the top surface of the switch base 1, the first magnetic sheet 14 and the second magnetic sheet 32 ​​are in contact and attracted to each other under the action of magnetic force, so that the protective cover 3 has good stability after being placed on the switch base 1, reducing the possibility of the protective cover 3 being accidentally opened.

[0031] like Figure 1 and Figure 3 As shown, an annular sealing groove 31 is provided on the bottom surface of the protective cover 3, and the sealing groove 31 is semi-cylindrical. A protrusion 13 that can cooperate with the inner wall of the sealing groove 31 is fixedly connected to the top surface of the switch seat 1. The protrusion 13 is annular and semi-cylindrical and surrounds the outside of the groove 11. The outer circumferential surface of the protrusion 13 is fixedly connected to a sealing sheet 131 that can fit tightly against the inner wall of the sealing groove 31.

[0032] When the protective cover 3 is covered on the top surface of the switch base 1, the protrusion 13 is inserted into the sealing groove 31 on the bottom surface of the protective cover 3, and the sealing sheet 131 will be in close contact with the inner wall of the sealing groove 31, so that the inside of the protective cover 3 has good air tightness, reducing the possibility of water vapor from the external environment entering the protective cover 3 in a humid environment and affecting the switch.

[0033] like Figure 1 and Figure 4 As shown, the top surface of the switch seat 1 is fixedly connected to a vent pipe 4 through a support rod. The vent pipe 4 is arranged in a ring shape. A plurality of air nozzles 41 connected to the inside of the vent pipe 4 are fixedly connected to the outer wall of the vent pipe 4. The plurality of air nozzles 41 are arranged obliquely downward toward the top surface of the sealing sheet 131. A pair of blowing mechanisms 5 respectively located outside the two sides of the groove 11 are also arranged on the top surface of the switch seat 1. The blowing mechanism 5 can blow air into the vent pipe 4 when the protective cover 3 is opened.

[0034] When the protective cover 3 is opened to control the opening and closing of the switch, the blowing mechanism 5 blows air into the ventilation pipe 4. The gas in the ventilation pipe 4 is ejected through the air nozzle 41 and blown onto the surface of the sealing sheet 131, thereby cleaning the sealing sheet 131 and causing dust and impurities adhering to the sealing sheet 131 to fall off, thereby reducing the possibility that impurities adhering to the sealing sheet 131 will affect the air tightness of the protective cover 3.

[0035] like Figure 1 and Figure 4As shown, the blowing mechanism 5 includes a shell 51, a pressure plate 52, an airbag 53 and a telescopic assembly 54. The shell 51 is fixedly connected to the top surface of the switch base 1, and a clearance opening 511 is opened on the top surface of the shell 51. The pressure plate 52 is vertically slidably connected to the inner wall of the shell 51. The airbag 53 is arranged inside the shell 51. The airbag 53 is located on one side of the pressure plate 52 close to the hinged portion of the protective cover 3 and the switch base 1. A connecting pipe 531 connected to the airbag 53 is fixedly connected to the airbag 53. The end of the connecting pipe away from the airbag 53 passes through the shell 51 and is fixedly connected to the side wall of the ventilation pipe 4 to communicate with the ventilation pipe 4. The telescopic assembly 54 is obliquely arranged on the top of the shell 51. One end of the telescopic assembly 54 passes through the clearance opening 511 and is hinged to the top surface of the pressure plate 52, and the other end is hinged to the inner wall of the protective cover 3.

[0036] When the protective cover 3 is opened, the telescopic component 54 drives the pressure plate 52 to squeeze the airbag 53. After the airbag 53 is pressurized, the internal gas enters the ventilation pipe 4 through the connecting pipe 531 and is sprayed out by the air nozzle 41 to clean the surface of the sealing sheet 131 by blowing. When the protective cover 3 is closed, the telescopic component 54 drives the slide plate 543 to slide away from the airbag 53, and the airbag 53 returns air, so that the sealing sheet 131 can be cleaned by blowing again when the protective cover 3 is opened next time.

[0037] like Figure 1 , Figure 4 and Figure 5 As shown, the telescopic assembly 54 includes a sleeve 541, a slide plate 543 and a slide rod 542. The sleeve 541 is tilted and arranged on the top of the shell 51. The end of the sleeve 541 close to the pressure plate 52 passes through the clearance opening 511 and is hinged on the top surface of the pressure plate 52. The slide plate 543 is coaxially connected to the inner wall of the sleeve 541. One end of the slide rod 542 is fixed to the end surface of the slide plate 543. The other end of the slide rod 542 extends to the outside of the sleeve 541 and is hinged on the inner wall of the protective cover 3. The slide rod 542 is slidably matched with the sleeve 541. The sleeve 541, the slide plate 543 and the slide rod 542 are coaxially arranged.

[0038] During the opening process of the protective cover 3, the slide bar 542 drives the slide bar 542 to gradually extend from the sleeve 541 and drives the slide plate 543 to slide along the inner wall of the sleeve 541. When the slide plate 543 moves to the end of the stroke, the slide bar 542 drives the sleeve 541 to pull the pressure plate 52 to move, so as to prompt the pressure plate 52 to squeeze the airbag 53 to spray. During the closing process of the protective cover 3, the sleeve 541, the slide bar 542 and the slide plate 543 are reset, and the airbag 53 returns to air, so that the airbag 53 can spray when it is squeezed next time.

[0039] like Figure 1 and Figure 6As shown, a lighting assembly 6 is arranged on the inner wall of the protective cover 3, and the lighting assembly 6 includes a lamp body 61, a power supply 62, a connecting plate 63, a first contact 65, a second contact 66 and an insulating partition 67. The lamp body 61 is mounted on the inner wall of the protective cover 3, the power supply 62 is mounted on the inner wall of the protective cover 3, the power supply 62 is electrically connected to the lamp body 61 through a first wire, the connecting plate 63 is fixedly connected to the inner wall of the protective cover 3, the first contact 65 is mounted on the side wall of the connecting plate 63 through a spring 64, the first contact 65 is electrically connected to the lamp body 61 through a second wire, the second contact 66 is fixedly connected to the inner wall of the protective cover 3, and the second contact 66 is located at the first contact 65 is on the side away from the connecting plate 63, the second contact 66 is electrically connected to the power supply 62 through the third wire, the second contact 66 can contact and cooperate with the first contact 65 to conduct the circuit, the insulating partition 67 is vertically fixed on the top surface of the switch base 1, and the insulating partition 67 can be inserted into the middle position between the first contact 65 and the second contact 66 after the protective cover 3 is closed to disconnect the circuit, and the connecting plate 63 is fixed with a guide sleeve 68 arranged along the expansion and contraction direction of the spring 64 on the side wall connected to the spring 64, and a guide column 69 with one end extending to the outside of the guide sleeve 68 is slidably connected to the inner wall of the guide sleeve 68, and the end of the guide column 69 away from the connecting plate 63 is connected to the side wall of the first contact 65.

[0040] When the protective cover 3 is in a closed state, the insulating partition 67 is inserted between the first contact 65 and the second contact 66, the circuit formed by the power supply 62, the lamp body 61, the first contact 65 and the second contact 66 is in a disconnected state, and the lamp body 61 is not lit; when the protective cover 3 is gradually opened, the insulating partition 67 gradually moves away from the position between the first contact 65 and the second contact 66, and the first contact 65 moves to contact with the second contact 66 under the elastic force of the spring 64, and the circuit formed by the power supply 62, the lamp body 61, the first contact 65 and the second contact 66 is connected, and the lamp body 61 is lit, so that when the protective cover 3 is opened, the lamp body 61 automatically illuminates the top surface of the switch seat 1, which is convenient for the staff to control the switch opening and closing in an environment with insufficient light. After the protective cover 3 is closed, the lamp body 61 automatically turns off to save energy.

[0041] Working principle: when the protective cover 3 is covered on the switch base 1, the second magnetic sheet 32 ​​on the side wall of the protective cover 3 contacts the first magnetic sheet 14 on the switch base 1, and the first magnetic sheet 14 and the second magnetic sheet 32 ​​attract each other under the action of magnetic force, so that the protective cover 3 is not easy to be opened at will. The switch handle 12 on the switch base 1 is protected by the covered protective cover 3, reducing the possibility of the switch handle 12 being accidentally touched. When the switch needs to be turned on and off, the protective cover 3 is opened, and the engaging portion 21 of the paddle 2 is inserted into the groove 11 and clamped on the switch handle 12. The switch handle 12 is driven to rotate by swinging the paddle 2 to realize the disconnection or closing of the circuit connecting the switch base 1 and the external device. After the paddle 2 is used, the paddle 2 is pulled out to prevent others from using it, effectively reducing the possibility of the switch handle 12 being accidentally touched and causing danger; When the protective cover 3 is in a closed state, the protrusion 13 will be inserted into the sealing groove 31, and the sealing sheet 131 arranged on the outer surface of the protrusion 13 will be in close contact with the inner wall of the sealing groove 31, so that the interior of the protective cover 3 has good air tightness and the possibility of water vapor entering the interior of the protective cover 3 is reduced. When the protective cover 3 is opened, the protective cover 3 drives the pressing plate 52 to move toward the direction close to the airbag 53 and squeeze the airbag 53 through the cooperation of the sliding rod 542, the sliding plate 543 and the sleeve 541. After the airbag 53 is compressed, the internal gas of the airbag 53 enters the ventilation pipe 4 through the connecting pipe 531 and is ejected through the air nozzle 41 to spray and clean the sealing sheet 131. When the protective cover 3 is closed, the protective cover 3 drives the sliding rod 542, the sliding plate 543 and the sleeve 541 to reset, and the airbag 53 returns air, so that the sealing sheet 131 is sprayed and cleaned once each time the protective cover 3 is opened; When the protective cover 3 is covered on the switch base 1, the insulating partition 67 is inserted in the middle position between the first contact 65 and the second contact 66. At this time, the circuit composed of the power supply 62, the lamp body 61, the first contact 65 and the second contact 66 is in a disconnected state, and the lamp body 61 is not lit; when the protective cover 3 is opened, the insulating partition 67 is moved away from the middle position between the first contact 65 and the second contact 66, and the first contact 65 contacts the second contact 66 under the elastic force of the spring 64, and the circuit composed of the lamp body 61, the power supply 62, the first contact 65 and the second contact 66 is turned on, and the lamp body 61 lights up for illumination, so as to illuminate the switch handle 12 under insufficient light conditions, so as to facilitate the staff to open and close the switch.
