DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-10 This application is described in further detail.

[0029] An embodiment of the present application provides a drawer cabinet.

[0030] refer to Figure 1 The drawer cabinet includes a cabinet body 1 and a heat dissipation mesh plate 7. The side walls on both sides of the cabinet body 1 are provided with openings. The heat dissipation mesh plate 7 is fixedly connected to the inner wall of the opening of the cabinet body 1. The heat dissipation mesh plate 7 can connect the interior of the cabinet body 1 with the outside world, which is convenient for heat dissipation, thereby improving the heat dissipation performance.

[0031] refer to Figure 2 and Figure 3 A support assembly 2 and a drawer 3 are provided in the cabinet 1. The support assembly 2 includes a support plate 21, a support roller 22 and an abutment plate 23. The support plate 21 is fixedly connected to the inner wall of the cabinet 1, the support plate 21 is horizontally arranged, and the support roller 22 is rotatably connected to the top side of the support plate 21.

When the drawer 3 slides on the support plate 21, the abutment plate 23 drives the support roller 22 to rotate, which can make the drawer 3 slide more smoothly.

[0032] refer to Figure 4 and Figure 5 , a partition device 4 is arranged in the cabinet 1, and the partition device 4 includes a receiving roller 41, a fireproof coil 42, a reset member 45 and a mounting block 46. The mounting block 46 is fixedly connected to the inner wall of the cabinet 1, and the axis of the receiving roller 41 is fixedly connected with a rotating shaft, and the receiving roller 41 is rotatably connected to the mounting block 46 through the rotating shaft. The fireproof coil 42 is made of fireproof material, and the fireproof coil 42 is wound on the receiving roller 41. In this embodiment, the reset member 45 specifically adopts a coil spring, and the reset member 45 is sleeved on the rotating shaft of the receiving roller 41, and the two ends of the reset member 45 are respectively connected to the mounting block 46 and the rotating shaft of the receiving roller 41. When the receiving roller 41 rotates, the reset member 45 undergoes elastic deformation, and the reset member 45 can reset the receiving roller 41, so that the fireproof coil 42 is rewound on the receiving roller 41.

[0033] refer to Figure 4 and Figure 6 The partition device 4 further includes a connecting strip 43, which includes a clamping plate 431 and a connecting member 432. For one connecting strip 43, two clamping plates 431 are provided, and the end of the fireproof coiled material 42 is located between the two clamping plates 431. In this embodiment, the connecting member 432 is specifically a screw, which passes through the two clamping plates 431 and the fireproof coiled material 42, and the two clamping plates 431 are fixedly connected by the connecting member 432, so that the two clamping plates 431 clamp the fireproof coiled material 42.

[0034] refer to Figure 4 and Figure 6 , the partition device 4 also includes a moving assembly 44, and the moving assembly 44 includes a guide rail 441, a slider 442 and a moving drive source 443. The guide rail 441 is fixedly connected to the inner wall of the cabinet 1, and the guide rail 441 is horizontally arranged, and the guide rail 441 is located between adjacent drawers 3. The slider 442 is slidably connected to the guide rail 441, and the clamping plate 431 is fixedly connected to the slider 442. In this embodiment, the moving drive source 443 specifically adopts a linear motor, and the moving drive source 443 drives the slider 442 to slide along the guide rail 441, so that the connecting strip 43 moves along the guide rail 441, thereby driving the accommodating roller 41 to unwind the fireproof coil 42, so that the fireproof coil 42 is unfolded between adjacent drawers 3. After the fireproof coil 42 is unfolded, the positive projection of the fireproof coil 42 covers the positive projection of the drawer 3, so that the adjacent drawers 3 can be partitioned, reducing the impact of the drawer 3 on other drawers 3 caused by the fire.

[0035] refer to Figure 7 and Figure 8 A clamping assembly 5 is provided on the support plate 21, and the clamping assembly 5 includes a clamping frame 51 and a clamping driving source 52. In this embodiment, the clamping driving source 52 is specifically an electric push rod, the body of the clamping driving source 52 is fixedly connected to the support plate 21, the moving end of the clamping driving source 52 is fixedly connected to the clamping frame 51, and the clamping driving source 52 can drive the clamping frame 51 to move up and down.

[0036] refer to Figure 3 and Figure 7 A compression groove 31 is provided on the top side of the drawer 3, and the compression frame 51 fits with the compression groove 31. After the fireproof coil 42 is unfolded, the compression driving source 52 drives the compression frame 51 to move, and the compression frame 51 drives the fireproof coil 42 to move into the compression groove 31, thereby covering the top side of the drawer 3, so that the drawer 3 forms a closed space, reducing the air from entering the drawer 3, thereby reducing the spread of fire. In this embodiment, the drawer 3 is provided with multiple groups, and the partition device 4 and the compression assembly 5 are correspondingly provided with multiple groups. When a fire occurs, multiple fireproof coils 42 can be unfolded at the same time, thereby reducing the impact of the drawer 3 on other drawers 3.

[0037] refer to Fig. 9 and Fig.10A sensor 6 is provided in the cabinet 1. The sensor 6 includes a smoke sensor 61 and a temperature sensor 62. The smoke sensor 61 and the temperature sensor 62 are both fixedly connected to the inner top wall of the cabinet 1. The temperature sensor 62 can detect the temperature in the cabinet 1, and the smoke sensor 61 can detect whether smoke appears in the cabinet 1. According to the detection of the smoke sensor 61 and the temperature sensor 62, it can be determined whether a fire occurs in the cabinet 1. The sensor 6 is electrically connected to the moving drive source 443 and the pressing drive source 52 respectively. When the sensor 6 detects a fire, it first controls the starting of the moving drive source 443, and then controls the starting of the pressing drive source 52, so that the fireproof coil 42 covers the drawer 3.

[0038] The implementation principle of a drawer cabinet in the embodiment of the present application is as follows: when there is no fire, the mobile driving source 443 moves the fireproof coil 42, and the reset member 45 resets the accommodating roller 41, so that the fireproof coil 42 is stored on the accommodating roller 41. At this time, the fireproof coil 42 moves out from between adjacent drawers 3, which is conducive to the heat dissipation of the drawer 3. When a fire occurs, the mobile driving source 443 moves the fireproof coil 42 between adjacent drawers 3, and the pressing driving source 52 drives the pressing frame 51 to move downward. The pressing frame 51 presses the fireproof coil 42 against the top side of the drawer 3, so that the fireproof coil 42 covers the top side of the drawer 3, reduces the air entering the drawer 3, and thus slows down the spread of the fire.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
