Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-7 As shown, an explosion-proof, fireproof and flame-retardant low-voltage distribution cabinet comprises: a box body 1, a cabinet body 3, an explosion-proof mechanism 4, a flame-retardant mechanism 5 and a fire-proof mechanism 6. The box body 1 is rotatably connected with two door bodies 2. A cabinet body 3 is arranged on the inner side of the box body 1. An explosion-proof mechanism 4 is arranged on the side of the cabinet body 3. The flame-retardant mechanism 5 is symmetrically arranged on the inner side of the box body 1. Ventilation slots 7 are symmetrically opened on the side of the box body 1. A fire-retardant mechanism 6 is slidably arranged on the side of the box body 1 than on the inner side. When the device is in use, ventilation and moisture-proofing are carried out through the ventilation slots 7 during daily use. When the box body 1 is subjected to severe impact, the cabinet body 3 is buffered and protected by the explosion-proof mechanism 4. When the inside of the box body 1 burns, the inside of the box body 1 is isolated from the outside by the flame-retardant mechanism 5, so that the inside of the box body 1 cannot be supplied with oxygen, which is convenient for preventing the fire from continuing to burn. When the outside of the box body 1 burns, it is isolated from the outside for protection by the fire-retardant mechanism 6 on the side of the box body 1.

[0025] The explosion-proof mechanism 4 includes a first connecting plate 41, a first shell 42, a first slider 43 and a first spring column 44. The rear end side wall of the cabinet 3 is connected to the first connecting plate 41. Two first connecting plates 41 are provided. The first shell 42 is symmetrically arranged between the two first connecting plates 41. The first shell 42 is slidably connected to the first slider 43. The first spring column 44 is arranged inside the first shell 42. Circular holes are opened at equal angles on the side of the first slider 43.

The second shells 46 are slidably connected to the second slider 47, and circular holes are opened at equal angles on the sides of the second slider 47. A second spring column 48 is arranged inside the second shell 46, and the second spring column 48 is connected to the second slider 47. The second slider 47 is connected to another second connecting plate 45. When the device is in use, when the box 1 is impacted, the first connecting plate 41 and the second connecting plate 45 on the side of the cabinet 3 are used to protect the impact, and the first shell 42 is slidably connected to the first slider 43 to buffer the impact force, and the first spring column 44 is used to buffer the impact force, and the second shell 46 is slidably connected to the second slider 47 to buffer the impact force, and the second spring column 48 is used to provide auxiliary buffering, and the circular holes opened on the sides of the first slider 43 and the second slider 47 facilitate the sliding of the first slider 43 and the second slider 47, thereby improving the sliding elasticity of the first slider 43 and the second slider 47.

[0027] Two driving motors 51 are symmetrically arranged at the upper end of the box body 1. The output shaft of the driving motor 51 is connected to a threaded rod 52. The threaded rod 52 is rotatably arranged inside the box body 1. Two sliding rods 53 are symmetrically arranged on the side of the threaded rod 52. The side of the threaded rod 52 is threadedly connected to a connecting rod 54, and the connecting rod 54 is slidably connected to the sliding rod 53.

[0028] The flame retardant mechanism 5 includes a first rotating rod 55, a first torsion spring 56 and a fire blanket 57. The first rotating rod 55 is embedded in the inner wall of the box body 1, and a first torsion spring 56 is arranged on the side of the first rotating rod 55. A fire blanket 57 is wound around the side of the first rotating rod 55, and the fire blanket 57 is connected to the connecting rod 54. When the device is in use and combustion occurs inside the device, the temperature monitor arranged at the upper end of the box body 1 is triggered, and the temperature monitor triggers the drive motor 51 to drive the threaded rod 52 to rotate. At the same time, the threaded rod 52 rotates and drives the connecting rod 54 to slide and descend on the side of the sliding rod 53. During the descent of the connecting rod 54, the fire blanket 57 is driven to descend, thereby blocking the ventilation slot 7, isolating external oxygen from entering the box body 1, and performing flame retardancy on the inside of the box body 1.

[0029] The fire prevention mechanism 6 includes a slide groove 61, a baffle 62, a third shell 63, a piston column 64, a second rotating rod 65 and a second torsion spring 66. Slide grooves 61 are provided on both sides of the box body 1. The baffle 62 is slidably connected to the inner side of the slide groove 61. The third shell 63 is symmetrically arranged on the inner side of the slide groove 61. The third shell 63 is slidably connected to the piston column 64. The second rotating rod 65 is rotatably connected to both sides of the slide groove 61. A second torsion spring 66 is arranged on the side of the second rotating rod 65.

[0030] A block 67 is connected to the side of the second rotating rod 65, and a fourth housing 68 is symmetrically arranged on the side of the block 67. The fourth housing 68 is slidably connected to the third slider 69. A third spring column 610 is arranged inside the fourth housing 68. The third spring column 610 is connected to the third slider 69. The third slider 69 is connected to a limit block 612 on the side. A protrusion 611 is connected to the side of the second rotating rod 65. When the device is in use, when combustion occurs outside the box body 1, the internal pressure of the third housing 63 increases due to the temperature of the combustion, thereby pushing the piston column 64 to rise. During the rising process of the piston column 64, the protrusion 611 on the side of the block 67 is pushed, so that the block 67 rotates on the side of the second rotating rod 65, and at the same time squeezes the third slider 69, so that the third slider 69 slides inside the fourth housing 68, squeezes the third spring column 610, and makes the limit block 612 rotate, loses the limit on the baffle 62, and the baffle 62 descends to block the ventilation slot 7, thereby preventing fire from the outside.

[0031] When the utility model is in use, ventilation and moisture prevention are carried out through the ventilation slots 7 during daily use;

[0032] When the box body 1 is impacted, the first connecting plate 41 and the second connecting plate 45 on the side of the cabinet body 3 are used to protect the impact, and the first housing 42 is slidably connected to the first slider 43 to buffer the impact force, and the first spring column 44 is used for buffering, and the second housing 46 is slidably connected to the second slider 47 to buffer the impact force, and the second spring column 48 is used for auxiliary buffering, and the circular holes opened on the sides of the first slider 43 and the second slider 47 facilitate the sliding of the first slider 43 and the second slider 47, thereby improving the sliding elasticity of the first slider 43 and the second slider 47;

[0033] When combustion occurs inside the device, the temperature monitor provided at the upper end of the box body 1 is triggered, and the temperature monitor triggers the driving motor 51 to drive the threaded rod 52 to rotate. At the same time, the threaded rod 52 rotates to drive the connecting rod 54 to slide down on the side of the sliding rod 53. During the descent of the connecting rod 54, the fire blanket 57 is driven to descend, and the ventilation slot 7 is blocked to prevent external oxygen from entering the box body 1, so that the inside of the box body 1 is flame-retardant.

[0034] When combustion occurs outside the box body 1, the internal pressure of the third shell 63 increases due to the combustion temperature, thereby pushing the piston column 64 to rise. During the rising process, the piston column 64 pushes the protrusion 611 on the side of the block 67, causing the block 67 to rotate on the side of the second rotating rod 65. At the same time, the third slider 69 is squeezed to slide inside the fourth shell 68, and the third spring column 610 is squeezed to cause the limit block 612 to rotate, losing the limit on the baffle 62. The baffle 62 descends to block the ventilation slot 7 to prevent fire from the outside.

[0035] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
