Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Reference Figures 1-2 A low-voltage incoming line cabinet support frame is mainly composed of a cabinet base 1. Four support legs 2 are welded to the bottom of the cabinet base 1 to ensure the stability of the entire frame. A fixing plate 3 is bolted to one side of the top of the cabinet base 1 for initial fixation of a portion of the low-voltage incoming line cabinet. The cabinet base 1 has an internal rotating shaft that rotatably connects to an adjusting rod 4. One end of the adjusting rod 4 is welded to a driven wheel 5. Rotating wheels 6 are also rotatably connected to the sides of the support legs 2 via rotating shafts. A gear belt 7 is arranged around the driven wheel 5 and the rotating wheel 6. A slide rail is designed on the surface of the adjusting rod 4, and a sliding seat 9 is slidably connected to the adjusting rod 4 via the slide rail. A movable frame plate 10 is bolted to the top of the sliding seat 9. When it is necessary to adjust the distance between the movable frame plate 10 and the fixing plate 3, simply rotate the adjusting rod 4. This rotates the rotating wheel 6 via the gear belt 7, thereby adjusting the height of the support leg 2. Simultaneously, the sliding seat 9 slides on the adjusting rod 4, adjusting the position of the movable frame plate 10. This design allows the low-voltage incoming cabinet to flexibly adjust the clamping position according to actual needs, avoiding shaking during use and improving the stability and effectiveness of use.

[0023] Inside the cabinet base 1, two sets of wheel grooves 101 and rod grooves 102 are symmetrically formed. The driven wheel 5 is located on the inner wall of the wheel groove 101, ensuring that the driven wheel 5 does not deviate from the predetermined path when rotating. The design of the wheel groove 101 also increases the stability of the driven wheel 5's rotation. The adjusting rod 4 is located on the inner wall of the rod groove 102, which guides and supports the adjusting rod 4, making its rotation more stable. This design enhances the stability and reliability of the driven wheel 5 and the adjusting rod 4 during operation, and improves the service life of the entire support frame.

[0024] The bottom of the support leg 2 is welded with a support base 201, which increases the support area and improves the stability of the chassis. A strip groove 202 is formed on the support base 201, which is designed to facilitate the firm fixation of the support chassis on the ground by bolts or other fixing members, preventing displacement or shaking during use. This design makes the support chassis more convenient and quick to install, and also improves the safety of use.

[0025] The side of the movable rack plate 10 away from the sliding seat 9 is welded with a limiting seat 11, which is internally designed with a sliding rail, and the limiting rod 12 is slidably connected with the limiting seat 11 through the sliding rail. The two ends of the limiting rod 12 are fixed on the cabinet base 1 by bolts, and by adjusting the position of the limiting rod 12 in the limiting seat 11, the movement range of the movable rack plate 10 can be further limited, and the stability of the entire support chassis can be improved. This design makes the movable rack plate 10 more stable and reliable during use, avoiding the problem of affecting the use effect due to shaking.

[0026] The side of the movable rack plate 10 is uniformly welded with three heat dissipation nets 1001, which are made of metal material and have good heat dissipation performance. The design of the heat dissipation net 1001 helps to dissipate the heat generated by the low-voltage incoming line cabinet during work in time, avoids the occurrence of overheating phenomenon, and prolongs the service life of the low-voltage incoming line cabinet. This design improves the heat dissipation performance of the low-voltage incoming line cabinet, and also increases the practicality of the entire support chassis.

[0027] The side of the fixed plate 3 and the movable rack plate 10 is respectively provided with a bolt slot 8, and the shape and size of the bolt slot 8 are matched with the mounting hole of the low-voltage incoming line cabinet. When installing the low-voltage incoming line cabinet, only the bolt needs to be screwed into the bolt slot 8 through the mounting hole. This design simplifies the installation process of the low-voltage incoming line cabinet, improves the installation efficiency and accuracy, and also facilitates the subsequent maintenance and replacement work.

[0028] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
