[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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] Example 1

[0025] like Figure 1 - Figure 4As shown, the utility model provides a technical solution: a low-voltage withdrawable switch cabinet, comprising: an adjusting mechanism 1, an inner wall of the adjusting mechanism 1 is provided with a heat dissipation mechanism 2, the adjusting mechanism 1 comprises a cabinet body 11, a side panel 12 is provided inside the cabinet body 11, the inside of the cabinet body 11 is fixedly connected to the bottom end of the side panel 12, a movable shaft 13 is provided inside the side panel 12, the inside of the side panel 12 is movably connected to the outside of the movable shaft 13, a hollow plate 14 is provided at the middle end of the movable shaft 13, the middle end of the movable shaft 13 is fixedly connected to one end of the hollow plate 14, a movable arm 110 is provided inside the hollow plate 14, the inside of the hollow plate 14 is slidably connected to the outside of the movable plate, a linear groove 111 is provided inside the movable plate, a slide groove 113 is provided inside the cabinet body 11, and the inner surface of the slide groove 113 is slidably connected to both sides of the drawer 112 The bottom of the drawer 112 is movably connected with the top of the movable arm 110, a gear 15 is provided at one end of the movable shaft 13, one end of the movable shaft 13 is fixedly connected to one side of the gear 15, a toothed plate 16 is provided on the outer side of the gear 15, the outer side of the gear 15 is meshed with the top of the toothed plate 16, a fixed plate 18 is provided at the bottom of the toothed plate 16, the bottom of the toothed plate 16 is fixedly connected to the top of the fixed plate 18, a telescopic rod 19 is provided on one side of the fixed plate 18, one side of the fixed plate 18 is fixedly connected to one end of the telescopic rod 19, the other end of the telescopic rod 19 is fixedly connected to one side of the inner wall of the cabinet 11, a slide groove 114 is provided on the inner wall of the cabinet 11, a slide groove 114 is provided on the inner surface of the slide groove 114, a slide rail 17 is provided, the inner surface of the slide groove 114 is slidably connected to one end of the slide rail 17, and one side of the slide rail 17 is fixedly connected to one side of the toothed plate 16.

[0026] In this embodiment, when the drawer 112 needs to be extended outward from the cabinet 11, the telescopic rod 19 is activated to extend it. During the extension process, the toothed plate 16 will be moved laterally, and will continuously mesh with the gear 15 during this process. When the gear 15 is powered by the meshing force, the movable shaft 13 will rotate, and the movable arm 110 in the hollow plate 14 will rotate in the same manner. As the drawer 112 rotates, it will gradually extend out of the cabinet 11. In order to completely move the drawer 112 out of the cabinet 11, a linear groove 111 is designed in the movable arm 110. During the extension process, the movable arm 110 will change its position due to the extension of the drawer 112, so that it can follow the extension of the drawer 112 as much as possible and maintain a relative position, thereby ensuring that the drawer 112 remains stable during the extension process, which is convenient for users to use. In this way, the drawer 112 is prevented from getting stuck or shaking due to poor friction or instability.

[0027] This mechanical opening and closing mode can effectively prevent the drawer 112 from moving disorderly or opening accidentally in the cabinet 11. Due to the design of the telescopic rod 19, the gear 15, the tooth plate 16 and the linear groove 111, the drawer 112 can only be smoothly pushed and pulled under the correct operation mode, and the drawer 112 will not move randomly in the cabinet 11 due to other reasons, thereby improving the safety and stability of the drawer 112. Therefore, the user can safely open and close the drawer 112 under normal use, ensuring the safety of the internal components of the drawer 112.

[0028] Example 2

[0029] like Figure 1 - Figure 4 As shown, the heat dissipation mechanism 2 includes a closing plate 21, a drawer 112 is arranged on the outer side of the closing plate 21, the outer side of the closing plate 21 is slidingly connected to the inside of the drawer 112, a ventilation plate 22 is arranged on the inner wall of the drawer 112, the inner wall of the drawer 112 is fixedly connected to the outer side of the ventilation plate 22, a drying box 23 is arranged on the inner side of the drawer 112, and the inner side of the drawer 112 is fixedly connected to one side of the drying box 23.

[0030] In this embodiment, by designing a drying box 23 on both sides of the inner wall of the drawer 112, the drying box 23 can delay the aging process of the components during the use of the switch cabinet, reduce corrosion and damage caused by excessive humidity, and thus extend the service life of the components. In addition, if heat dissipation is required, the closing plate 21 can be pushed to both sides in the drawer 112 to expose the ventilation plate 22, and the drawer 112 can be directly ventilated and heat dissipated. This design can help the components in the drawer 112 to dissipate heat, improve the working efficiency and stability of the components, and also help to keep the temperature of the components within a safe range. If not needed, the two closing plates 21 can be fitted again, and can be adjusted as needed.

[0031] Working principle:

[0032] like Figure 1 - Figure 4As shown, when the new type is used, according to the needs of the user, the telescopic rod 19 is activated to extend it. During the extension process, the tooth plate 16 will be moved laterally, and will continuously mesh with the gear 15 during the process. When the gear 15 is powered by the meshing, the movable shaft 13 will rotate, and the movable arm 110 in the hollow plate 14 will rotate in the same way. As the drawer 112 rotates, it will gradually extend out of the cabinet body 11. In order to completely move the drawer 112 out of the cabinet body 11, a linear groove 111 is designed in the movable arm 110. During the extension process, the movable arm 110 will change its position due to the extension of the drawer 112, so that it can follow the extension of the drawer 112 as much as possible and maintain a relative position, thereby ensuring that the drawer 112 remains stable during the extension process, which is convenient for users to use.

[0033] By designing the drying box 23 on both sides of the inner wall of the drawer 112, the drying box 23 can delay the aging process of the components during the use of the switch cabinet, reduce corrosion and damage caused by excessive humidity, and thus extend the service life of the components. In addition, if heat dissipation is required, the closing plate 21 can be pushed to both sides in the drawer 112 to expose the ventilation plate 22, and the drawer 112 can be directly ventilated and cooled. This design can help the components in the drawer 112 to dissipate heat, improve the working efficiency and stability of the components, and also help to keep the temperature of the components within a safe range.
