DETAILED DESCRIPTION

[0025] This specific embodiment is an elevator control cabinet maintenance box, and its structural diagram is as follows Figure 1-Figure 7 As shown, it includes a box body 1, a top cover 2 is assembled on the top of the box body 1, a control button and a socket are provided on the top cover 2, a wiring terminal 3 is provided near the top surface of the inner cavity of the box body 1, two screws 5 are rotatably connected to the bottom surface of the inner cavity of the box body 1, two screw sleeves 4 are fixedly connected to the top surface of the wiring terminal 3, the screws 5 are threadedly connected to the screw sleeves 4, a transmission assembly is provided at the bottom end of the screw 5, a protective cover 13 is movably connected to the top surface of the upper cover 2, and one end of the protective cover 13 is opened to prevent the protective cover 13 from getting stuck when the protective cover 13 is pushed open.

[0026] like Figure 3 and Figure 7 As shown, the transmission assembly includes a worm gear 6 fixedly connected to the side wall of the screw 5. The worm gear 6 is located below the terminal 3. A worm 7 is rotatably connected to the inner wall of the box body 1. The worm 7 meshes with the worm gear 6. One end of the worm 7 passes through the box body 1 and is fixedly connected to a rotating block 8. By setting up the transmission assembly, the rotating block 8 can be used to drive the worm gear 6 to rotate, so that the worm 7 drives the two screws 5 to rotate synchronously, achieving the effect of raising and lowering the terminal 3.

[0027] like Figure 7 As shown, two limit plates 9 are fixedly connected to the side walls of the terminal block 3, and two limit rods 10 are fixedly connected to the bottom surface of the inner cavity of the box body 1. The limit rods 10 pass through the limit plates 9 and are movably connected to them. This can limit the position of the terminal block 3, ensuring that the terminal block 3 is in a vertical lifting state, improving its stability and smoothness.

[0028] like Figure 3 As shown, the top end surface of the screw rod 5 is equipped with a positioning plate 11, which is connected to the screw rod 5 by bolts. When the terminal block 3 needs to be removed, the positioning plate 11 is removed, and the terminal block 3 can be removed for replacement or maintenance.

[0029] like Figure 4-Figure 6 As shown, two card boxes 12 are symmetrically fixedly connected to the top surface of the upper cover 2, and two card blocks 14 are fixedly connected to the side wall of the protective cover 13, and the card boxes 12 are adapted to the card blocks 14.

[0030] The side walls of the card block 14 are fixedly connected to the first magnetic block 16 , and the side walls of the card box 12 are fixedly connected to the second magnetic block 15 . The first magnetic block 16 is adapted to the second magnetic block 15 .

[0031] Specifically, the protective cover 13 can be limited by using the card block 14 and the card box 12, and the end face of one end of the card box 12 is a closed structure to prevent the card block 14 from detaching from the card box 12, effectively improving its practicality, and in conjunction with the first magnetic block 16 and the second magnetic block 15, the protective cover 13 can be supported and positioned.

[0032] Working principle: When it is necessary to connect or maintain the terminal 3, first use a wrench to rotate the rotating block 8 to drive the worm 7 to rotate, and the worm 7 engages with the worm wheel 6 to drive the screw 5 to rotate. The screw 5 drives the terminal 3 to rise to a suitable height through the screw sleeve 4, which is convenient for the staff to connect or maintain the terminal 3. After the wiring or maintenance is completed, the rotating block 8 is reversed to drive the terminal 3 to descend. When maintenance operations need to be performed through the control button on the upper cover 2, the protective cover 13 is directly pushed to the appropriate position, so that the first magnetic block 15 and the second magnetic block 16 are attracted, and then the control operation is performed to effectively achieve the protective effect.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
