[0002] An electric control cabinet is a device used for centralized control, power distribution and protection of various electrical equipment. It assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in an enclosed or semi-enclosed metal cabinet or panel to meet the requirements of the normal operation of the power system, facilitate maintenance, and ensure the safety of personnel and surrounding equipment. A contact box is an insulating bushing used to install static contacts and provide electrical insulation isolation between grounding components such as mounting plates and busbars. It is widely used in various trolley-type electric control cabinets.
[0003] In the existing electric control cabinet, there is a contact box, and static contacts are arranged in the contact box and are used in cooperation with the moving contacts on the trolley circuit breaker. When the moving contacts on the trolley circuit breaker are separated from the static contacts in the contact box, it is necessary to isolate the static contacts to prevent electric power construction personnel from accidentally touching the static contacts during construction in the electric control cabinet. Since the existing movable door plate for isolating static contacts is controlled by a connecting rod structure and uses the friction between the movable door plate and the sleeve rod and partial supporting force of the connecting structure to maintain static state, the movable door plate without a stable fixing structure may suddenly fall during use, which may cause electric power construction personnel to accidentally touch the static contacts. Therefore, we provide a movable door plate on a contact box of an electric control cabinet. Summary of the Utility Model

[0027] In this embodiment, by setting the trap door body 13, after the static contact on the contact box is separated from the moving contact on the trolley circuit breaker, the static contact on the contact box can be isolated, preventing electric power construction personnel from getting an electric shock due to accidental contact with the static contact. By setting the fixing mechanism 2, the trap door body 13 can be firmly fixed, so that the trap door body 13 will not suddenly fall when isolating the static contact. In addition, an arc surface 16 is formed on the latch 14, enabling the latch 14 to squeeze and adjust the bevel block 21. A slot 17 is formed on the latch 14, allowing the bevel block 21 to be snap-connected to the latch 14, making the trap door body 13 more stable. By setting the adjusting block 26, the position of the trap door body 13 can be changed when actually needed, enabling the static contact on the contact box to cooperate with the moving contact on the trolley circuit breaker.
[0028] Embodiment 2
[0029] As Figures 1 - 5 As shown in the figure, a connecting block 25 is fixedly connected to the outer surface of the round block 22. The connecting block 25 penetrates through the interior of the first mounting rod 11 and is slidably connected to the first mounting rod 11. One end of the connecting block 25 away from the round block 22 is fixedly connected to an adjusting block 26. One end of a spring 23 is fixedly connected to the outer surface of the round block 22, and the other end of the spring 23 is fixedly connected to the inner wall of the first mounting rod 11. A slider 15 is provided at one end of the trap door body 13 away from the latch 14. The slider 15 is fixedly connected to the trap door body 13 and penetrates through the interior of the second mounting rod 12. The slider 15 is slidably connected to the second mounting rod 12. Bolts 18 penetrate through the interiors of both the first mounting rod 11 and the second mounting rod 12, and the bolts 18 are slidably connected to both the first mounting rod 11 and the second mounting rod 12.
[0030] In this embodiment, by setting the spring 23, under the action of the spring 23, the snap connection between the bevel block 21 and the latch 14 can be made tighter. At the same time, the spring 23 can be compressed to generate elastic force. Then, under the action of the elastic force of the spring 23, the bevel block 21 can automatically reset after being squeezed and adjusted and directly snap-connect to the latch 14, improving the convenience of fixing the position of the trap door body 13. At the same time, a limiting block 24 is provided, and the limiting block 24 is placed in a limiting groove formed inside the first mounting rod 11, and thus can cooperate with the connecting block 25 and the adjusting block 26 to guide the movement of the round block 22 so that it will not be affected by the spring 23 during sliding.
[0031] Working principle:
[0032] As Figures 1 - 5As shown in the figure, when the utility model is in use, it can be firmly connected to the electric control cabinet through the bolt 18, so that the movable door panel body 13 can be placed at an appropriate position inside the electric control cabinet. When the static contact on the contact box is separated from the dynamic contact on the trolley circuit breaker, the movable door panel body 13 can be slid upward. At this time, when the movable door panel body 13 is slid upward, the movable door panel body 13 will drive the clamping block 14 to slide inside the first mounting rod 11 and drive the slider 15 to slide inside the second mounting rod 12. At this time, as the movable door panel body 13 continuously rises, the clamping block 14 will contact the bevel block 21 and squeeze the bevel block 21 by using the arc surface 16, so that the bevel block 21 slides into the first mounting rod 11. At the same time, the bevel block 21 will compress the spring 23 by using the round block 22, so that the spring 23 generates elastic force. When the position of the movable door panel body 13 is appropriate and the static contact on the contact box can be completely isolated, the clamping block 14 will stop sliding, and the elastic force of the spring 23 will be released. The elastic force of the spring 23 will act on the round block 22 and the bevel block 21. At this time, the round block 22 will drive the bevel block 21 to reset under the guidance of the limiting block 24 and make the bevel block 21 tightly engaged in the card slot 17 opened on the clamping block 14. At this time, the movable door panel body 13 is in a stable state, and the electric power construction personnel will not accidentally touch the static contact on the contact box. If it is necessary to reset the movable door panel body 13, the adjusting block 26 can be used to drive the connecting block 25 to slide. Then, the connecting block 25 will drive the bevel block 21 to slide by using the round block 22, so that the clamping connection between the bevel block 21 and the clamping block 14 is released. At this time, the movable door panel body 13 will automatically fall and will not affect the cooperation between the static contact on the contact box and the dynamic contact on the trolley circuit breaker.
[0033] The above is only a preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
