Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to an adjustable electric 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 electrical energy 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] A Chinese patent publication (publication number: CN217823868U) discloses a height-adjustable low-voltage electrical distribution cabinet, which includes a distribution cabinet body and a base, wherein a hinge is rotatably provided on one side of the distribution cabinet body facing the back, a side plate is fixedly provided on the hinge close to the distribution cabinet body, the side plate is rotatably fitted with the inner surface of the distribution cabinet body, a fixing assembly is fixedly provided on the upper surface of the distribution cabinet body, and a lifting assembly is fixedly provided between the lower surface of the distribution cabinet body and the base;

[0004] Although the height of the electrical distribution cabinet can be adjusted, there will be a certain gap between the base and the distribution cabinet after the adjustment. At this time, moisture and dust will enter the inner cavity of the base, and moisture and dust will affect the service life of the motor. Utility Model Content

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and do not limit the protection scope of the utility model.

[0023] It should be noted that when an element is referred to as being "fixed to", "disposed on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. Further, when an element is considered to be "fixedly connected to" another element, the two may be fixed in a detachable connection manner or in a non-detachable connection manner, such as socketing, snap-on, one-piece fixation, welding, etc., which can be achieved in the prior art and will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0026] Combined with Figure 1 and 2 An adjustable electrical distribution cabinet of the present embodiment includes a distribution cabinet 1, a box body 2 is provided at the bottom of the distribution cabinet 1, the distribution cabinet 1 is arranged directly above the box body 2, a lifting structure for adjusting the upper and lower heights of the distribution cabinet 1 is provided in the box body 2, the distribution cabinet 1 moves up and down relative to the box body 2 under the control of the lifting structure to adjust the height, a flexible protective cover 3 is connected between the distribution cabinet 1 and the box body 2, the flexible protective cover 3 is arranged around the distribution cabinet 1 and the box body 2, the upper end of the flexible protective cover 3 is sealed connected to the distribution cabinet 1, and the lower end of the flexible protective cover 3 is sealed connected to the box body 2.

[0027] When the height of the distribution cabinet 1 changes, the flexible protective cover 3 can adaptively adjust its shape and always seal the gap between the distribution cabinet 1 and the box body 2 to prevent moisture and dust from entering the inner cavity of the box body 1 and affecting the service life of the inner cavity parts of the box body 2.

[0028] As a preferred solution of the present utility model, the flexible protective cover 3 is a folding structure similar to an accordion protective cover.

[0029] As a preferred embodiment of the utility model, the lifting structure includes a threaded rod 4, a threaded sleeve 5 and a driving mechanism. The threaded rod 4 is arranged at the center of the box body 1 and is rotatably connected to the box body 2. The threaded sleeve 5 is fixedly connected to the bottom center of the distribution cabinet 1. The threaded sleeve 5 is threadedly sleeved on the threaded rod 4. The driving mechanism is used to control the rotation of the threaded rod 4. When the driving mechanism controls the rotation of the threaded rod 4, the threaded rod 4 drives the threaded sleeve 5 to move up and down, thereby driving the distribution cabinet 1 to move up and down to achieve the purpose of height adjustment.

[0030] As a preferred solution of the utility model, the driving mechanism includes a rotating shaft 6, one end of which is arranged close to the threaded rod 4, and the threaded rod 4 and the rotating shaft 6 are matched through a bevel gear set 10. The rotating shaft 6 is manually controlled to rotate to drive the distribution cabinet to adjust the height. Compared with electric drive, the operation is simpler and the cost is low. The height of the distribution cabinet can also be adjusted without electricity.

[0031] As a preferred embodiment of the present invention, the other end of the rotating shaft 6 extends to the outer surface of the box body 2, the outer end of the rotating shaft 6 does not protrude from the outer surface of the box body 2, and a control groove 7 is provided on the end face of the rotating shaft 6. The control groove 7 is a special-shaped groove, such as a rhombus, hexagon, etc. Only when a specific tool matching the special-shaped groove is inserted into the special-shaped groove can the rotating shaft 6 be controlled to rotate, thereby preventing the rotating shaft 6 from being illegally rotated by people.

[0032] As a preferred solution of the utility model, since the length of the rotating shaft 6 is relatively long, in order to improve the bending resistance of the rotating shaft 6, a support ring 8 is sleeved on the middle part of the rotating shaft 6, and the rotating shaft 6 is rotatably connected to the support ring 8, and the support ring 8 is fixedly connected to the box body 2. Multiple support rings 8 can be arranged simultaneously along the length direction of the rotating shaft 6.

[0033] As a preferred solution of the utility model, the lifting structure also includes a telescopic rod 9 for connecting the distribution cabinet 1 and the box body 2. The telescopic rod 9 is staggered with the lifting structure. The telescopic direction of the telescopic rod 9 is parallel to the axis of the threaded rod 4, mainly to limit the rotation of the distribution cabinet 1.

[0034] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
