Description

Technical Field

[0001] The utility model belongs to the technical field of power distribution cabinets, and in particular relates to a low-voltage power distribution cabinet. Background Art

[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box). It is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] The Chinese patent application number in the prior art is CN210898475U, which discloses a plugging device for the incoming line side of a distribution cabinet. The device includes a bent pipe with one end mounted on the elbow on the incoming line side of the distribution cabinet, a gasket inserted into the inner cavity of the other end of the bent pipe and mounted on the cable, and fasteners for fixing the two ends of the bent pipe; the bent pipe is provided with a first expansion joint running through the entire bent pipe in the busbar direction, and the gasket is provided with a second expansion joint running through the entire gasket in the busbar direction; the bent pipe and the gasket are made of flexible material.

[0004] The existing power distribution cabinet inlet has weak protection against animals entering the distribution cabinet, and only relies on bent pipes for protection. If the diameter of the wire is smaller than the bent pipe, the protection will be greatly reduced. It can only be used for wires of specified thickness and the scope of application is also small. For this reason, we propose a low-voltage power distribution cabinet. Utility Model Content

[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

[0025] See also Figure 1-Figure 4 , the technical solution provided by this embodiment is as follows:

[0026] A low-voltage power distribution cabinet comprises a cabinet body 1, a mounting plate 2 is fixedly connected to the side of the cabinet body 1, a wire inlet 5 is opened on the side of the mounting plate 2, a shell 3 and a positive slide rail 6 are fixedly connected to the side of the mounting plate 2, the wire inlet 5 and the positive slide rail 6 are located in the shell 3, a retraction mechanism is arranged between the wire inlet 5 and the positive slide rail 6, the retraction mechanism comprises a turntable 4 and a plurality of concentric plates 7, the turntable 4 is rotatably connected in the shell 3, a plurality of slide grooves 8 are opened on the side of the turntable 4, the plurality of concentric plates 7 are located between the turntable 4 and the positive slide rail 6, a first slider 9 and a second slider 10 are fixedly connected to the two sides of the concentric plate 7 respectively, the first slider 9 is slidably connected in the corresponding slide groove 8, and the second slider 10 is slidably connected in the corresponding positive slide rail 6.

[0027] In a specific embodiment of the present utility model, the mounting plate 2 is installed at the inlet or outlet of the cabinet 1. During installation, the line enters the cabinet 1 from the inlet port 5. However, different cables have different thicknesses. In order to ensure that the line can enter, the traditional inlet port 5 is usually designed with a larger diameter to leave enough free space. However, it is easy for small animals to enter the interior of the cabinet 1 from the inlet port 5, which may cause damage to the equipment and affect normal use. In this scheme, a shell 3, a turntable 4, a positive slide rail 6 and a concentric plate 7 are designed around the inlet port 5. The concentric plate 7 is limited between the positive slide rail 6 and the turntable 4. When in use, the turntable 4 is rotated to drive the concentric plates 7 to move synchronously, so that the concentric plates 7 expand or contract synchronously. The space between the concentric plates 7 can be flexibly adjusted. The cable passes through the concentric plates 7, so that the size of the inlet space can be flexibly adjusted according to the thickness of the cable. The concentric plates 7 can fit around the cables, greatly reducing the remaining space, thereby preventing small animals from entering and improving safety.

[0028] Specifically, a paddle 11 is fixedly connected to the edge of the turntable 4 , an outer groove 301 is formed on the circumferential surface of the housing 3 , and the paddle 11 is slidably connected in the outer groove 301 .

[0029] In a specific embodiment of the utility model, the paddle 11 extends through the outer groove 301 to the outside of the housing 3 , and the dial 4 can be rotated by turning the paddle 11 . The structure is simple and easy to operate, and it is convenient for staff to use.

[0030] Specifically, the side of the mounting plate 2 is fixedly connected with an arc-shaped slide rail 13 , the surface of the arc-shaped slide rail 13 is slidably connected with a slide sleeve 12 , the slide sleeve 12 is fixed to the side of the paddle 11 , and the surface of the arc-shaped slide rail 13 is sleeved with a spring 14 .

[0031] In a specific embodiment of the utility model, the sliding sleeve 12 moves with the paddle 11. When the concentric plates 7 expand, the sliding sleeve 12 moves in the direction of the spring 14. The spring 14 is compressed. After the paddle 11 is released, the paddle 11 can be pushed by the spring 14, so that the multiple concentric plates 7 shrink synchronously and fit around the cable, providing automation of the mechanical system.

[0032] Specifically, the positive slide rail 6 is a regular polygon, and the number of the concentric plates 7 is the same as the number of sides of the positive slide rail 6 .

[0033] In a specific embodiment of the present utility model, the preferred positive slide rail 6 is a regular hexagonal structure, and six concentric plates 7 are provided, which can be made of plastic material with low cost and easy assembly.

[0034] Specifically, the housing 3 and the turntable 4 are both provided with a circular groove having the same diameter as the line inlet 5 .

[0035] In a specific embodiment of the utility model, the cable needs to pass through the housing 3, the turntable 4 and the cable inlet 5 during installation, which is easy to do if the diameters are the same, thus reducing obstruction.

[0036] Working principle: When in use, the turntable 4 is rotated to drive the concentric plates 7 to move synchronously, so that the concentric plates 7 can be expanded or contracted synchronously. The space between the concentric plates 7 can be flexibly adjusted. The cable passes through the concentric plates 7, so that the size of the incoming line space can be flexibly adjusted according to the thickness of the cable. The concentric plates 7 can fit around the cable, greatly reducing the remaining space, thereby preventing small animals from entering and improving safety.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
