[0024] Reference Figures 1 to 4The interlocking and anti-misoperation device for a primary and secondary fusion ring network box shown in the figure comprises a box body 1 and a pair of box doors 10. The box doors 10 are hinged to one end of the box body 1. The box body 1 and the box doors 10 can be used to isolate and protect the electrical appliances inside the ring network box to prevent the danger of touching the bottom. It also comprises an interlocking component 2 and a pair of anti-mistaken touch components 3. The anti-mistaken touch component 3 is installed on the box body 1. The anti-mistaken touch component 3 is used to prevent the box door 10 from opening when the interlocking component 2 is unlocked. The interlocking component 2 comprises a shell 20, a pair of buttons 21, a pair of sliders 22, a pair of plug blocks 23, a pair of round rods 24 and a pair of reset springs 25. The top of the shell 20 is fixedly connected to the top wall of the box body 1. A groove 100 is provided on the top of the opposite side of the two box doors 10. The inner wall of the groove 100 is fitted with the shell body 20. A slot 101 is provided on the inner wall of the groove 100. The slot 101 is plugged with the plug block 23. The plug block 23 passes through the side wall of the shell 20 and is inserted into the plug block 23. It is slidably connected, the bottom of the plug block 23 is fixedly connected to the top of the round rod 24, a guide groove 220 is provided on the top of the slider 22, the guide groove 220 is slidably connected to the round rod 24, the slider 22 can be horizontally slidably installed in the shell 20, one end of the slider 22 is fixedly connected to the button 21, the button 21 passes through the side wall of the shell 20 and is slidably connected thereto, the two buttons 21 are both semicircular and fit each other, by providing a pair of buttons 21 and arranging them in a fit with each other, one of the buttons 21 can be pressed separately to open a box door 10 separately, and it is also convenient to press the two buttons 21 at the same time to open the two box doors 10 at the same time, and the operation is flexible and changeable. The return spring 25 is installed on the housing 20, and the return spring 25 is used to provide a horizontal thrust to the button 21; when the door 10 is pushed to close, the door 10 and the plug 23 collide with each other, pushing the plug 23 to slide into the housing 20. After the door 10 is fitted with the box body 1, the thrust provided by the return spring 25 pushes the slider 22 to slide horizontally in the housing 20, pushing the button 21 out of the housing 20, and the round rod 24 moves along the guide groove 220 on the slider 22, driving the plug 23 to insert into the slot 101, which can fix the door 10 and play a locking role. When the button 21 is located in the housing 20, the plug 23 is separated from the slot 101; at this time, the interlocking assembly 2 is in the unlocked state, and the door 10 can be opened by pulling the handle on the door 10. When one end of the button 21 protrudes from the housing 20, one side of the plug 23 is located in the slot 101 and conflicts with its inner wall. At this time, the interlocking assembly 2 is in a locked state, which can prevent the door 10 from being accidentally opened.

[0025] Two anti-accidental touch components 3 are symmetrically distributed on both sides of the box body 1. The anti-accidental touch components 3 include a pair of U-shaped fixing plates 30 and a pair of tension springs 31. One of the U-shaped fixing plates 30 is fixedly connected to the inner wall of one side of the box body 1, and the other U-shaped fixing plate 30 is fixedly connected to one of the box doors 10. The two ends of the tension spring 31 are respectively fixedly connected to the inner walls of the two U-shaped fixing plates 30. When an accidental touch occurs, when the button 21 is pushed into the housing 20, the interlocking component 2 is in an unlocked state. At this time, since the tension spring 31 is always in a stretched state, its rebound tendency provides a horizontal tension acting on the box door 10, so that the box door 10 and the box body 1 are in a closed state, avoiding the risk of electric shock caused by the opening of the box door 10 when an accidental touch occurs.

[0026] The housing 20 has a cavity 200 formed inside, the cavity 200 is slidably connected to the slider 22, one end of the return spring 25 is fixedly connected to the inner wall of the cavity 200, and the other end of the return spring 25 is fixedly connected to the slider 22. When the insert block 23 is pushed into the housing 20, the return spring 25 is compressed as the slider 22 moves, and after the door 10 is closed, the return spring 25 rebounds, providing a thrust to push the slider 22, and the slider 22 slides back to its original position in the cavity 200, thereby inserting the insert block 23 into the slot 101.

[0027] The interlocking assembly 2 further includes a pair of L-shaped rods 26 and a pair of plug rods 27. The two L-shaped rods 26 are symmetrically distributed on both sides of the box body 1. A slide groove 102 and a circular groove 103 are provided on one side of the box door 10. The slide groove 102 is slidably connected to one side of the L-shaped rod 26. The plug rod 27 passes through the L-shaped rod 26 and plugs into the circular groove 103. When the box door 10 needs to remain in a normally open state, the handle on the box door 10 is pulled to open the box door 10 and rotated 90 degrees. Then, the plug rod 27 is pulled out to one side to disengage it from the circular groove 103. The L-shaped rod 26 slides down along the slide groove 102. At this time, one side of its bottom contacts the box door 10 and one end contacts the box body 1, which can prevent the box door 10 from closing automatically. When the box door 10 needs to be closed, it only needs to move the L-shaped rod 26 and insert the plug rod 27 back into the circular groove 103 to prevent the L-shaped rod 26 from falling.

[0028] The anti-accidental touch assembly 3 also includes a pair of fixed blocks 32 and a cover plate 33. The fixed block 32 is fixedly connected to one end of the housing 20. The top two sides of the cover plate 33 are rotatably connected to the two fixed blocks 32. One end of the cover plate 33 is in contact with the housing 20, and the inner wall of the cover plate 33 is in contact with the button 21. When the cover plate 33 is in a horizontal state, the button 21 is exposed, which is convenient for pressing. When the cover plate 33 is in a vertical state, the button 21 is located inside the cover plate 33. At this time, the button 21 can be protected by the cover plate 33 to further prevent accidental touches.

[0029] The anti-mis-touch assembly 3 also includes a pair of spring dampers 34, which are symmetrically distributed on both sides of the housing 20. A pair of fixing grooves 201 are provided at one end of the housing 20. One end of the spring damper 34 is fixedly connected to the inner wall of the fixing groove 201, and the telescopic end of the spring damper 34 is in contact with the top of one end of the door 10. When the door 10 is closed, the tension spring 31 contracts to drive the door 10 to rotate, which does not require manual pushing and is relatively labor-saving. When the door 10 contacts the spring damper 34, the spring damper 34 contracts to absorb the impact force of the door 10, which can avoid damage caused by collision.
