[0002] During each inspection process of the protection device in the power system, there are multiple protection devices in a distribution panel, and each protection device has different functions. When individually inspecting one of the protection devices in the panel, it is necessary to conduct switching-on and switching-off experiments on the configured control power supply air switch, protection power supply air switch, and device power supply air switch. However, when switching the air switch on and off, it is easy to accidentally switch off the air switches of other adjacent protection devices, leading to unnecessary accidents.

[0003] The existing Chinese patent with the application number 202223500724.1 proposed an anti-misoperation device for switching-on and switching-off switches. It includes a protective shell, the protective shell is in a shape of a capital "J", a through hole is provided in the middle of the upper end face, a cover plate is provided at the through hole, and the upper end of the cover plate is rotatably connected to the upper end face of the protective shell, enabling the cover plate to block or disengage from the through hole. Magnetic blocks are provided on the lower end faces of the two ends of the protective shell. Both the protective shell and the cover plate are made of transparent organic glass. When inspecting the protection device in the panel, the utility model protects the power supply air switches of other protection devices, avoiding the occurrence of accidentally switching on and off the air switches.

It is only installed on the device by magnetic adsorption, which is not stable enough and is easily affected by the outside world, resulting in falling or offset, with insufficient stability. At the same time, when the staff needs to operate the switch for switching-on and switching-off, the cover plate will come into contact with the staff's hand under the influence of its own weight, thereby affecting the staff's hand operation, which is rather inconvenient. Content of the Utility Model

[0020] 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.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: including a housing component 1 and an opening and closing component 2, the housing component 1 includes an isolation housing 101, a through-type operating cavity 104 is provided on the front of the isolation housing 101, a vertical groove is provided on the front of the two side surfaces of the operating cavity 104, and an anti-mistaken touch sealing plate 106 is movably inserted in the two vertical grooves;

[0022] The opening and closing assembly 2 comprises a vertical shaft 201, a spring 202 is sleeved on the top of the shaft body of the vertical shaft 201, a top plate 203 is fixedly installed on the top of the vertical shaft 201, a vertical rod 204 is fixedly installed on the bottom front of the top plate 203, an operating frame 205 is fixedly installed on the bottom end of the vertical rod 204, an operating opening is opened on the front of the operating frame 205, a roller 206 is rotatably installed at the bottom of the operating opening, a sleeve rotating seat 207 is fixedly sleeved on the bottom of the shaft body of the vertical shaft 201, both sides of the sleeve rotating seat 207 are rotatably connected to a transmission rod 208, and the other ends of the two transmission rods 208 are rotatably installed with a connecting rotating seat 209;

[0023] The two connecting rotating seats 209 correspond to the two anti-accidental touch sealing plates 106 one by one, and the front side of the connecting rotating seat 209 is fixedly connected to the middle part of the back side of the anti-accidental touch sealing plate 106 .

[0024] In this embodiment, a docking plate 102 is fixedly installed at the rear edges of the top and bottom surfaces of the isolation shell 101, and a hanging block 103 is fixedly installed on the back of the two docking plates 102. By inserting the hanging block 103 into the hanging groove, the device can be quickly and conveniently installed on the equipment. It is not only convenient to install, but also relatively stable after installation.

[0025] A magnetic patch 107 is fixedly installed on the opposite surfaces of the two anti-accidental-touch sealing plates 106, and the opposite surfaces of the two magnetic patches 107 are arranged to attract each other with opposite poles. Under the adsorption effect of the two magnetic patches 107, the two anti-accidental-touch sealing plates 106 will merge together, thereby automatically covering the opening and closing switch positions of the power equipment to prevent misoperation, which is more practical.

[0026] A circular opening is provided in the middle of the front end of the top of the isolation shell 101 , and the vertical shaft 201 is movably inserted in the circular opening. The top end of the spring 202 is fixedly connected to the bottom surface of the top plate 203 , and the bottom end of the spring 202 is fixedly connected to the top surface of the isolation shell 101 .

[0027] A transparent plate 105 is fixedly mounted on the top of the front of the operating chamber 104. The transparent plate 105 is made of acrylic material, which can provide protection without affecting the staff's observation of the opening and closing switches in the device.

[0028] When in use, align the hanging block 103 fixedly installed on the back of the docking plate 102 with the pre-set hanging groove on the surface of the device, and then insert the hanging block 103 into the hanging groove to quickly and conveniently install the device on the device. It is not only convenient to install, but also relatively stable after installation. Moreover, when the device needs to be disassembled later, it only needs to be manually lifted diagonally upwards to conveniently remove the device.

[0029] At the same time, the device can be used to cover the opening and closing switch positions of the power equipment to prevent misoperation, and the device will not affect the staff's use of the opening and closing switches while avoiding misoperation. Specifically, when it is necessary to perform opening and closing operations, the staff can insert their hands into the operating openings on the front of the operating frame 205. After insertion, the operating frame 205 is driven down by the hand, and the descent of the operating frame 205 can drive the vertical rod 204 to descend. The descent of the vertical rod 204 can drive the top plate 203 to descend, and the descent of the top plate 203 can drive the vertical shaft 201 to descend and compress the rear surface of the bottom of the top plate 203. The spring 202 is arranged on the vertical shaft 201, and the descent of the vertical shaft 201 will drive the sleeve rotating seat 207 fixed at its bottom end to descend. Since both sides of the sleeve rotating seat 207 are rotatably connected with a transmission rod 208, and the other ends of the two transmission rods 208 are connected to the back of an anti-accidental touch sealing plate 106 through a connecting rotating seat 209, as the sleeve rotating seat 207 descends, the distance between the bottom ends of the transmission rods 208 will increase, thereby causing the two anti-accidental touch sealing plates 106 to move to both sides and separate. After separation, the staff can easily reach into the operating chamber 104 to operate the opening and closing switches.

[0030] When the hand is inserted, the roller 206 will facilitate the movement of the staff's hand, making the movement of the staff's hand smoother. After the operation is completed, after the hand is retracted from the operation frame 205, under the action of the spring 202, the top plate 203 will rise, thereby driving the vertical axis 201 to rise, and the rising of the vertical axis 201 will drive the sleeve rotating seat 207 to rise. After the sleeve rotating seat 207 rises, it will drive the two anti-mistaken touch sealing plates 106 to approach each other. After they are close to a certain distance, under the adsorption action of the two magnetic stickers 107, the two anti-mistaken touch sealing plates 106 will merge together, so that the opening and closing switch positions of the power equipment can be automatically covered to prevent misoperation, which is more practical.

[0031] To sum up, the device for preventing misoperation of the opening and closing switch can quickly and conveniently install the device on the device by aligning the hanging block 103 fixedly installed on the back of the docking plate 102 with the hanging groove preset on the surface of the equipment, and then inserting the hanging block 103 into the hanging groove. It is not only convenient to install, but also relatively stable after installation. Moreover, when the device needs to be disassembled later, it only needs to be manually lifted diagonally upward to conveniently remove the device. At the same time, the device can be used to cover the opening and closing switch position of the power equipment to prevent misoperation. While avoiding misoperation, the device will not affect the use of the opening and closing switch by the staff, and is more practical.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
