Description

Technical Field

[0001] This utility model belongs to the field of switch equipment technology and relates to a structure for enhancing drawer stability. Background Technology

[0002] In existing switchgear, drawers used to support electrical components such as circuit breakers are mostly box-type structures constructed from metal partitions made of zinc, steel, and other metal materials. These structures have a certain capacity and load-bearing capacity. However, the connection strength between the partitions in the spliced ​​structure is limited, and the overall strength of the drawer is also limited. In particular, the increased partition area in large-sized drawer structures further weakens the strength. However, the components inside the drawers in existing switchgear have a large combined weight and an uneven center of gravity, which puts a heavy load on the drawers. This makes existing partition-type drawers prone to deformation and loosening of the connection structure. Some manufacturers have solved the strength problem by thickening the partitions, but this has also added the problems of excessive drawer weight and high cost. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a structure that enhances the stability of drawers.

[0031] This embodiment provides a structure to enhance drawer stability, as shown in the reference. Figure 1 It includes a frame structure consisting of drawer side panels, drawer front panel 2, drawer bottom panel and support.

[0032] Reference Figure 2 and Figure 3The drawer side panels include a left side panel 12 and a right side panel 11, which are respectively located on the left and right sides of the drawer front panel 2. The left side panel 12 and the right side panel 11 are fixedly connected to the drawer front panel 2 and the drawer bottom panel. Both the left side panel 12 and the right side panel 11 are provided with heat dissipation mesh holes for effective heat dissipation of electrical components inside the drawer.

[0033] The bracket is used to connect with the left side panel 12 and the right side panel 11, providing lateral support between the left side panel 12 and the right side panel 11. One or more brackets can be provided, and they can be set at any set position such as the front end, rear end, top end, and bottom end of the drawer frame. They can provide adaptive multi-point support in combination with the internal layout of the drawer, fully ensuring the overall strength of the drawer frame structure.

[0034] Preferred, refer to Figure 4 and Figure 5 The bracket has a straight strip structure, and its two ends in the straight direction are bent to form connecting ends 32 for contacting and connecting with the left side plate 12 and the right side plate 11. Preferably, the connecting ends 32 are bent at a 90-degree angle relative to the bracket. When the bracket is installed, the two connecting ends 32 at both ends of the bracket form surface-to-surface contact with the left side plate 12 and the right side plate 11 respectively, improving the support strength.
