Description

Technical Field

[0001] The invention relates to a power distribution cabinet with hidden wheels and a use method thereof, belonging to the technical field of power distribution cabinets. Background Art

[0002] The distribution cabinet is the final equipment of the power distribution system. It is a cabinet used for centralized installation of various control, protection and display devices. Whether in residential electricity use, factory electricity use, or power transmission, the application of distribution cabinets is very extensive. At present, the distribution cabinet is installed on the ground with mounting feet and screws, but in some special occasions, a movable distribution cabinet is required.

[0003] The existing movable distribution cabinet is simply equipped with universal wheels at the bottom of the cabinet. After being moved to a designated position, the universal wheel structure is unstable and prone to failure due to long-term load.

[0004] In order to solve the above problems, the present invention proposes a distribution cabinet with hidden wheels, which can slide down when moving and retract when not in use. Compared with the existing technology, it can ensure the stable support and easy movement of the distribution cabinet. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a distribution cabinet with hidden wheels and a method of use.

[0006] To achieve the above-mentioned object, the present invention adopts the following technical solution: a power distribution cabinet with hidden wheels, comprising a power distribution cabinet body, a bottom bearing plate provided at the bottom of the power distribution cabinet body, a support frame fixedly connected to the bottom of the bottom bearing plate, and a lifting platform insertion port provided on the side of the support frame;

[0007] A wheel mounting opening is provided at the bottom of the bottom bearing plate and located on the inner side of the supporting frame, and a hidden wheel structure is provided on the inner side of the wheel mounting opening.

[0008] As a further description of the above technical solution:

[0009] The hidden wheel structure includes an installation box, the interior of the installation box is fixedly connected to a support frame, the support frame is L-shaped, and the inner part of the installation box is divided into a support area and a cavity area, the bottom and side of the support frame are provided with a first slide, the side of the first slide is provided with a sliding member, the side of the sliding member is fixedly connected to a sliding rod, and the sliding rod is located inside the first slide, and the bottom of the sliding member is provided with a caster.

[0010] As a further description of the above technical solution:

[0011] A second slide is provided on the inner side wall of the installation box and is located below the first slide. A rotating rod is movably connected to the side of the sliding member, and the rotating rod is located inside the second slide.

[0012] As a further description of the above technical solution:

[0013] The right end of the second slide is provided with an oblique opening, and the inner side wall of the wheel mounting opening is fixedly connected with a safety support plate.

[0014] As a further description of the above technical solution:

[0015] The support frame is composed of two groups of frame frames, and multiple groups of reinforcement frames are arranged between the support frame and the bottom bearing plate.

[0016] As a further description of the above technical solution:

[0017] An anti-collision plate is provided on the side of the bottom bearing plate, and the anti-collision plate is made of a stainless steel metal shell.

[0018] As a further description of the above technical solution:

[0019] A frame-shaped clamping plate is fixedly connected to the side surface of the anti-collision plate, and the frame-shaped clamping plate is slidably connected to the side surface of the bottom bearing plate.

[0020] A method for using a power distribution cabinet with hidden wheels, the method comprising the following steps:

[0021] When it is necessary to move, the lifting device is inserted into the insertion port of the lifting platform to lift the bottom load plate so that the bottom end of the support frame is suspended in the air. At this time, the sliding member and the caster are manually slid down along the first slide, and then slid horizontally to the bottom of the support frame. At the same time, the movable rotating rod also slides into the second slide. At this time, the lifting device is removed;

[0022] When the movement is completed, the hidden wheel structure is retracted into the cavity area of ​​the inner part of the installation box, so that the support frame supports the distribution cabinet.

[0023] The present invention has the following beneficial effects:

[0024] 1) Compared with the existing technology, this distribution cabinet with hidden wheels has a support frame structure installed at the bottom of the bottom load-bearing plate, and the bottom is in direct contact with the ground to support the distribution cabinet. When it needs to be moved, the distribution cabinet can be moved by the hidden wheel structure. It is very convenient to use and can avoid the long-term load of the wheels and the reduction of service life.

[0025] 2) By providing the first slide structure, the sliding member can slide along the first slide, so that the caster can be retracted into the interior of the installation box or extended from the interior of the installation box for use, which is very convenient.

[0026] 3) By providing a second slide structure, when the sliding member and the caster slide to the use position (when they need to bear the gravity of the entire distribution cabinet), the rotating rod on the side of the sliding member slides into the interior of the second slide, which can greatly increase the connection strength between the sliding member and the slide rail and increase the service life of the caster structure.

[0027] 4) By providing an oblique opening at the right end of the second slide, the rotating rod can slide into the interior of the second slide easily. The safety support plate provided can also prevent the rotating rod from falling and affecting the use of the caster. The safety support plate is provided with a detachable connection, which can facilitate the installation of the sliding part.

[0028] 5) The two sets of frame frames are set opposite to each other, but not aligned in the middle, forming the lifting platform insertion holes on both sides. The lifting platform insertion holes make it easy to insert the lifting device under the bottom load-bearing plate, lift the distribution cabinet a little, and slide the hidden wheel structure down. The reinforcement frame can increase the connection strength between the support frame and the bottom load-bearing plate.

[0029] 6) Due to the design structure requiring the side of the bottom load-bearing plate to protrude partially, the function of the anti-collision plate is to prevent people or other devices from hitting the side of the bottom load-bearing plate.

[0030] 7) The frame-type card plate structure can facilitate the installation, removal and replacement of the anti-collision plate. BRIEF DESCRIPTION OF THE DRAWINGS
