It is mainly composed of an incoming line cabinet, an outgoing line cabinet, a capacitor cabinet, a metering cabinet, a busbar interconnection cabinet, and other parts. It can realize the functions of receiving, distributing, converting, controlling, protecting, and monitoring electrical energy. The low-voltage cabinet is equipped with control components such as PLCs, and programming devices such as computers and programmers are often used. In addition, during factory testing, on-site debugging, and daily maintenance, a support platform is usually required to place the above-mentioned equipment, that is, a bracket with a tray is required. However, the tray brackets for low-voltage cabinets currently on the market, in order to adapt to the use of different heights, mostly adopt a liftable setting to support the equipment at different heights. However, most of the current tray brackets are driven by structures such as screws and cylinders, and the installation space on the cabinet is large, occupying the usable space of the low-voltage cabinet. Therefore, the inventor proposed a low-voltage cabinet tray bracket. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] This specific embodiment is a low-voltage cabinet tray bracket, and its structural diagram is as follows Figure 1 As shown, it includes a cabinet door 1, a supporting mechanism 3 and a limiting mechanism 2. The cabinet door 1 is provided with a receiving groove 4, and the receiving groove 4 is distributed in two groups at intervals. The supporting mechanism 3 is arranged in the receiving groove 4.
[0024] Reference Figure 2 The carrying mechanism 3 includes a carrying plate 5 and a rotating shaft 6. A connecting hole 7 is opened inside the carrying plate 5. The rotating shaft 6 passes through the connecting hole 7. The carrying plate 5 is fixedly connected to the rotating shaft 6. The two ends of the rotating shaft 6 are respectively rotated to connect the inner wall of the accommodating groove 4; a limiting mechanism 2 is fixed on the inner side wall of the accommodating groove 4, and the limiting mechanism 2 limits and fixes the rotating shaft 6.
[0025] Reference Figure 3 、 Figure 4The limiting mechanism 2 includes a fixed rod 12, a limiting plug rod 9, and a pull rod 13. A limiting hole 8 is provided on the outer wall of the rotating shaft 6, and the limiting plug rod 9 is adapted to be plugged into the limiting hole 8. The fixed rod 12 is fixedly fitted with the inner wall of the accommodating groove 4, and a sliding cavity 17 is vertically provided inside the fixed rod 12. The limiting plug rod 9 is inserted from the top of the sliding cavity 17, and one end that slides in is fixedly connected to a connecting ring 11. The bottom end face of the connecting ring 11 is fixedly connected to a spring 10, which is arranged vertically, and the other end is fixedly connected to a fixing ring 15. The connecting ring 11 and the fixing ring 15 are coaxially distributed, and the fixing ring 15 is fixedly connected to the inner wall of the sliding cavity 17. A through hole 16 is provided in the middle of the fixing ring 15, and a pull rod 13 is movably passed through the through hole 16. The top of the pull rod 13 is fixedly connected to the connecting ring 11, and the spring 10 is sleeved on the outside of the screw. A pull ring 14 is fixedly connected to the bottom of the pull rod 13 , and the pull ring 14 is located below and outside the fixed rod 12 .
[0026] Working principle: When in use, the cabinet door 1 is hinged to the low-voltage cabinet. When the load-bearing plate 5 is needed to support the equipment, the load-bearing plate 5 of the corresponding height is turned out of the receiving slot 4. The load-bearing plate 5 rotates ninety degrees and changes from the storage state to the unfolded state. The load-bearing plate 5 drives the rotating shaft 6 to rotate synchronously. There is a limiting hole 8 on the outer wall of the rotating shaft 6. The unfolded limiting hole 8 rotates downward and corresponds to the limiting mechanism 2. When the limiting hole 8 corresponds to the limiting plug 9, the spring 10 pushes the connecting ring 11 up. The spring 10 uses the fixing ring 15 as the support point, and the connecting ring 11 drives the limiting plug 9 to move up. The limiting plug 9 pops out and inserts into the limiting hole 8 correspondingly, and then the rotating shaft 6 is fixed. The supporting plate 5 can also be fixed after being unfolded, so that computers, programmers and other equipment can be placed. The supporting plate 5 in the corresponding position can be unfolded according to the use requirements. The supporting plate 5 is embedded and cooperates with the cabinet door 1. It takes up little space and will not affect the internal space of the low-voltage cabinet. When the supporting plate 5 is used, pull the pull ring 14, and the pull ring 14 moves down. The pull ring 14 pulls the connecting ring 11 through the pull rod 13. The connecting ring 11 is forced to move downward, and the spring 10 is compressed. The connecting ring 11 approaches the fixed ring 15, and then the limiting rod 9 above the connecting ring 11 is forced to leave the limiting hole 8, and the rotating shaft 6 can be rotated to put the supporting plate 5 into the accommodating groove 4. Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
