Before a fire occurs inside the distribution cabinet, the telescopic airbag expands and opens the electric telescopic rod, thereby blocking the ventilation slot with the flame-retardant plate. This isolates the inside of the distribution cabinet from oxygen. As the flame-retardant plate moves, the locking plate locks the L-shaped limiting plate, preventing the distribution cabinet door from being opened.

When the flame-retardant plate moves downwards, the pushing column will hit the connecting block, thereby causing the entire connecting plate and U-shaped clamping plate to detach from the main body of the distribution cabinet. This prevents the rollers from being jammed and unable to move in the event of a fire. Attached Figure Description

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0027] Example 1
[0028] like Figs. 1-5 As shown, this embodiment proposes a low-voltage distribution cabinet with a high flame retardant structure, including a distribution cabinet body 1, a distribution cabinet door 2 on the side of the distribution cabinet body 1, a distribution cabinet handle 3 on the side of the distribution cabinet door 2, and a ventilation slot 4 on the side of the distribution cabinet body 1.
[0029] The main body 1 of the power distribution cabinet is provided with a flame-retardant structure 5, which includes a support plate 51. The support plate 51 is fixedly connected to the side of the main body 1 of the power distribution cabinet. An electric telescopic rod 52 is provided at the bottom of the support plate 51. A flame-retardant plate 53 is fixedly connected to the telescopic end of the electric telescopic rod 52. A telescopic airbag 55 is fixedly passed through the side of the main body 1 of the power distribution cabinet. A fixing plate 56 is fixedly connected to the bottom of the support plate 51. An electric telescopic rod switch 57 is provided on the side of the fixing plate 56.
[0030] The flame-retardant plate 53 has a first magnetic block 54 inside, and the inner wall of the main body 1 of the power distribution cabinet has a second magnetic block 58. The second magnetic block 58 is fixedly connected to the side of the card plate 59, and the side of the power distribution cabinet door 2 is fixedly connected to the L-shaped limit plate 510. The design of the flame-retardant plate 53 can block the entire ventilation slot 4 and effectively isolate the fire source.
[0031] The side of the first magnetic block 54 is magnetically connected to the side of the second magnetic block 58. The number of the side of the first magnetic block 54 and the second magnetic block 58 are set to two sets, and they are symmetrical to each other along the vertical central axis of the main body of the distribution cabinet 1. The design of the side of the first magnetic block 54 and the second magnetic block 58 is to move the card plate 59 through the flame retardant plate 53.
[0032] The electric telescopic pole switch 57 is located on the side of the telescopic airbag 55, and the control end of the electric telescopic pole switch 57 is located on the movement trajectory of the telescopic end of the telescopic airbag 55. The design of the telescopic airbag 55 can automatically open the electric telescopic pole switch 57 when the temperature inside the distribution cabinet is too high.
[0033] The L-shaped limit plate 510 is located directly below the card plate 59, and the interior of the L-shaped limit plate 510 is located on the bottom displacement trajectory of the card plate 59. The design of the L-shaped limit plate 510 and the card plate 59 is to lock the distribution cabinet door 2.
[0034] In this embodiment, in the initial stage of a fire inside the main body 1 of the distribution cabinet, the high temperature will cause the telescopic airbag 55 to expand. At this time, the telescopic airbag 55 will push against the electric telescopic rod switch 57, thereby activating the electric telescopic rod 52. After the electric telescopic rod 52 is activated, it will move the flame-retardant plate 53 downward. The flame-retardant plate 53 moves downward until it blocks the entire ventilation slot 4. This can prevent oxygen from outside the distribution cabinet from entering the main body 1 of the distribution cabinet, thus preventing the fire from developing further. During the downward movement of the flame-retardant plate 53, the first magnetic block 54 inside the flame-retardant plate 53 will move the second magnetic block 58 downward. This will also move the locking plate 59. When the flame-retardant plate 53 is in place, the locking plate 59 will lock inside the L-shaped limiting plate 510 on the distribution cabinet door 2. This can lock the distribution cabinet door 2 tightly to prevent it from being opened and causing other losses.
[0035] Example 2
[0036] like Figs. 1-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes a low-voltage distribution cabinet with a high flame retardant structure. The main body 1 of the distribution cabinet is provided with a movable structure 6. The movable structure 6 includes a fixed base 67. The bottom of the fixed base 67 is fixedly connected to the bottom of the main body 1 of the distribution cabinet. A rotating shaft 68 is fixedly passed through the inside of the fixed base 67. A roller 69 is rotatably connected to the circumference of the rotating shaft 68. The design of the movable structure 6 can facilitate the movement of the main body 1 of the distribution cabinet.
[0037] The bottom of the main body 1 of the power distribution cabinet is provided with a sliding groove 61. A sliding block 62 is slidably connected inside the sliding groove 61. A connecting plate 63 is fixedly connected to the top of the sliding block 62. A U-shaped card plate 66 is fixedly connected to the side of the connecting plate 63. The design of the connecting plate 63 is to connect the U-shaped card plate 66.
[0038] A connecting block 64 is fixedly connected to the side of the connecting plate 63, and a U-shaped handle 65 is fixedly connected to the side of the connecting plate 63. A push column 610 is fixedly connected to the bottom of the flame-retardant plate 53. The U-shaped handle 65 is designed to move the connecting plate 63 more easily.
[0039] The roller 69 is located on the side of the U-shaped plate 66, and the circumferential surface of the roller 69 is located on the displacement trajectory inside the slot of the U-shaped plate 66. The design of the U-shaped plate 66 can hold the roller 69 in place and prevent it from rolling.
[0040] The connecting block 64 is located directly below the push post 610, and the top of the connecting block 64 is located on the displacement trajectory of the bottom of the push post 610. The push post 610 is designed to push the connecting block 64 away, preventing it from locking the roller 69 in an emergency.
[0041] In this embodiment, when using the power distribution cabinet, if it is necessary to move the entire power distribution cabinet body 1, it can be pushed by the bottom roller 69 to quickly move the power distribution cabinet body 1. After moving to the appropriate position, the connecting plate 63 can be pushed inward by the U-shaped handle 65, so that the sliding block 62 slides the connecting plate 63 into the sliding groove 61, thereby locking the roller 69 in the groove of the U-shaped clamping plate 66. In this way, the power distribution cabinet body 1 will no longer move. In the event of a fire, as the flame-retardant plate 53 moves downward, it will bring the pushing column 610 to hit the connecting block 64. After the connecting block 64 is hit by the impact force, the sliding block 62 will disengage from the sliding groove 61, thereby moving the U-shaped clamping plate 66 on the connecting plate 63 away from the roller 69, preventing the roller 69 from being locked by the U-shaped clamping plate 66 in dangerous situations.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
