A first translation plate 16 is provided on the top wall of each of the two second connecting plates 15. Two first triangular plates 22 are installed on the top wall of each of the two first translation plates 16. Multiple anti-slip strips 26 are fixedly installed at equal intervals on the side wall of the two second connecting plates 15 that are close to each other. The second connecting device includes two first connecting plates 14, which are located on the side of the two second connecting plates 15 that are close to each other. A second triangular plate 29 is provided above each of the two first connecting plates 14. Multiple anti-slip strips 26 are also fixedly installed at equal intervals on the side wall of the two first connecting plates 14 that are far from each other. A driving block 13 is provided on the top wall of the cover plate 11. A first abutment plate 31 and a second abutment plate 32 are fixedly installed on the two sides of the driving block 13. The first abutment plate 31 is located below the second abutment plate 32. A driving box 12 is fixedly installed on the top wall of the cover plate 11.

[0020] It is worth noting that the enclosure 10 and its specific usage have already been disclosed in the anti-accidental contact closed power supply box (202422105169.5), and will not be repeated here. The two magnets 24 have opposite positive and negative poles, so they can attract each other.

[0021] In practical use, the first connecting device can limit the cover plate 11 on the box 10 by the two second connecting plates 15 approaching each other and mating with the left and right side walls of the box 10. The second connecting device can limit the cover plate 11 on the box 10 by the two first connecting plates 14 moving away from each other and mating with the left and right side walls of the cavity of the box 10. The up and down movement of the driving block 13 can quickly move the first and second connecting plates 15, allowing the user to quickly connect the cover plate 11 to the box 10 or detach the cover plate 11 from the box 10.

[0022] In summary, by setting up the first connecting device and the second connecting device, the first connecting plate 14 and the second connecting plate 15 can be moved by the up and down movement of the drive block 13 to connect the cover plate 11 to the box body 10, or to quickly detach the cover plate 11 from the box body 10, which can effectively save time and effort for the staff.

[0023] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a translation groove 18 is provided on the top wall of the cavity of the cover plate 11, a limiting groove 19 is provided on the top wall of the translation groove 18, and a first through hole 20 is provided on the top wall of the cover plate 11. The first through hole 20 and the limiting groove 19 are interconnected.

[0024] A second translation plate 23 is fixedly installed on the top wall of the second connecting plate 15. A first translation plate 16 is fixedly installed on the top wall of the second translation plate 23. The first translation plate 16 is movably installed in the cavity of the limiting groove 19. The second translation plate 23 is movably installed in the cavity of the translation groove 18. The first triangular plate 22 extends out of the first through hole 20.

[0025] A magnet 24 is fixedly installed on the side wall of each of the two second translation plates 23 that are close to each other, and a connection hole 25 is opened on the top wall of the first translation plate 16 and the second translation plate 23.

[0026] In practical use, when the two magnets 24 approach each other through magnetic force, they can drive the two second translation plates 23 to move towards each other. The movement of the second translation plates 23 can drive the second connecting plate 15 to move. The movement of the second connecting plate 15 can cooperate with the anti-slip strip 26 to clamp the left and right side walls of the box 10, thereby connecting the cover plate 11 to the box 10. When the first triangular plate 22 is forced to move away from each other, it can drive the two first translation plates 16 to move away from each other. The movement of the first translation plates 16 can drive the second connecting plate 15 to move, thereby disengaging the second connecting plate 15 from the box 10. The limiting groove 19 can limit the first translation plate 16. The connection between the limiting groove 19 and the first translation plate 16 allows the second connecting plate 15 to move in parallel. The translation groove 18 can limit the second translation plate 23.

[0027] In summary, by setting up the housing 10, cover plate 11, second connecting plate 15, first translation plate 16, translation groove 18, limiting groove 19, first triangular plate 22, second translation plate 23, magnet 24, connecting hole 25 and anti-slip strip 26, the second connecting plate 15 can be connected to the housing 10 by the operation of the two magnets 24, and then the cover plate 11 can be connected to the housing 10. The cover plate 11 can be detached from the housing 10 by the operation of the first triangular plate 22.

[0028] like Figure 7 and Figure 8 As shown, a connecting block 27 is fixedly installed on the top wall of the first connecting plate 14. The connecting block 27 extends out of the connecting hole 25. A base plate 30 is fixedly installed on the top wall of the connecting block 27. A second triangular plate 29 is fixedly installed on the top wall of the base plate 30. A spring 28 is installed between the side wall of the two second triangular plates 29 that are far apart from each other and the left and right side walls inside the cavity of the drive box 12.

[0029] The second abutment 32 corresponds to the position of the first triangular plate 22, the first abutment 31 corresponds to the position of the second triangular plate 29, a second through hole 21 is provided on the bottom wall of the drive box 12, the drive block 13 is movably installed in the cavity of the second through hole 21, and the lower left and right side walls of the drive block 13 abut against the two magnets 24.

[0030] A fixing plate 33 is fixedly installed on both the front and rear side walls of the drive block 13. An electric cylinder 35 is fixedly installed on the top wall of the housing 10. The movable end of the electric cylinder 35 is fixedly connected to the bottom wall of the front fixing plate 33. A limiting post 34 is also fixedly installed on the top wall of the housing 10. The limiting post 34 passes through the rear fixing plate 33 and is movably connected to the rear fixing plate 33. The electric cylinder 35 is electrically connected to the power supply and switch.

[0031] In practical use, when the movable end of the electric cylinder 35 moves upward, it can drive the front fixed plate 33 to move upward. The movement of the front fixed plate 33 can drive the drive block 13 to move upward. The connection between the rear fixed plate 33 and the limiting post 34 allows the drive block 13 to move smoothly. The movement of the drive block 13 can disengage from the two magnets 24, causing the two magnets 24 to approach each other through magnetic force. When the drive block 13 moves upward, it can also drive the first abutment plate 31 to move upward. The movement of the first abutment plate 31 can push the two second triangular plates 29 to move away from each other through the inclined wall of the second triangular plate 29. The movement of the second triangular plates 29 can drive the base plate 30 to move. The movement of the base plate 30 can drive the connecting block 27 to move. The movement of the connecting block 27 can drive the first connecting plate 14 to move. The movement of the first connecting plate 14 can drive the anti-slip strip 2... The first connecting plate 14 is connected to the inner wall of the cavity of the housing 10 by moving the 6th section. The anti-slip strip 26 increases the friction and prevents the second connecting plate 15 and the first connecting plate 14 from detaching from the housing 10. When the drive block 13 moves downward, it can drive the first abutment 31 to move downward, so that the first abutment 31 loses the pushing force on the second triangular plate 29. Then the spring 28 can push the second triangular plate 29 to reset through its force, thereby driving the first connecting plate 14 to reset. The downward movement of the drive block 13 can also drive the second abutment 32 to move downward. The movement of the second abutment 32 can cooperate with the inclined wall of the first triangular plate 22 to push the two first triangular plates 22 to move away from each other, thereby detaching the second connecting plate 15 from the housing 10. The second through hole 21 can limit the drive block 13, and the side cavity 36 can limit the second connecting plate 15.

[0032] In summary, by setting up a drive box 12, a drive block 13, a first connecting plate 14, a first through hole 20, a second through hole 21, a connecting block 27, a spring 28, a second triangular plate 29, a base plate 30, a first abutment plate 31, a second abutment plate 32, a fixing plate 33, a limiting post 34, an electric cylinder 35, and a side cavity 36, the operation of the electric cylinder 35 can drive the drive block 13 to move up and down, thereby driving the first connecting plate 14 and the second connecting plate 15 to move. The up and down movement of the drive block 13 can quickly connect or disconnect the cover plate 11 from the box body 10, which is convenient to use and has a simple structure.
