[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a drawer-type power distribution cabinet which is convenient for installing electrical components. Background Art

[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box), which is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. Among them, the functional unit of the drawer-type distribution cabinet is separated from the busbar or cable by a grounded metal plate or a functional board made of plastic, forming three areas of the busbar, functional unit and cable. There are also isolation measures between each functional unit. The drawer-type switch cabinet has high reliability, safety and interchangeability. It is a relatively advanced distribution cabinet. They are suitable for industrial and mining enterprises and high-rise buildings that require high power supply reliability as a centralized control distribution center.

[0003] Existing drawer-type power distribution cabinets need to be frequently pulled out during use to facilitate the installation of electrical components. However, sufficient length of wires must be reserved for pulling out to ensure that telecommunications will not restrict the movement of the drawer, thereby ensuring the stability of the wires. However, the wires are messy inside, and it is not easy to dissipate heat when the electrical components are concentrated in one place.

[0004] As disclosed in Chinese patent CN216489314U, a drawer-type distribution cabinet is provided, which includes a cabinet body; support legs fixed to the outer surface of the cabinet body for supporting the cabinet body; an installation portion arranged inside the cabinet body; and a heat dissipation portion fixed inside the cabinet body for dissipating heat from the cabinet body. The drawer-type distribution cabinet provided by the utility model can facilitate the installation of electrical components, and compared with ordinary distribution cabinets, the distribution cabinet provided by the utility model has the advantages of being able to automatically adjust the position of the electrical components when pulling them out, and being able to facilitate the heat dissipation of the electrical components, etc., which is used to solve the problem in the prior art that when installing electrical components in the drawer-type distribution cabinet, sufficient length of wires need to be reserved for pulling them out, so as to ensure that telecommunications will not restrict the movement of the drawer, but the wires are messy inside, and the electrical components are concentrated in one place and are not easy to dissipate heat.

[0005] However, when the power distribution cabinet is in a drawer, since the wires need to be connected to the internal components, a certain length of wires will be reserved when the drawer is pulled out, which makes the wires easy to become messy and easy to fold and damage. If the components move inside the drawer, the connection of the components may become unstable, causing inconvenience in use.

[0006] For this reason, we urgently need to provide a drawer-type power distribution cabinet that is convenient for installing electrical components. Utility Model Content

DETAILED DESCRIPTION

[0027] 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.

[0028] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0029] Embodiment 1:

[0030] A drawer-type power distribution cabinet for convenient installation of electrical components comprises a power distribution cabinet 1, wherein the power distribution cabinet 1 has a cabinet structure on its surface, a drawer-type structure is installed inside the cabinet structure, and a movable buffer structure is arranged at the bottom of the cabinet structure.

[0031] The drawer-type structure includes a pull-out unit and a cable management unit. The cable management unit includes a winding wheel 305, torsion springs 306 are connected to the left and right sides of the winding wheel 305, a blocking block 307 is connected to the end of the torsion spring 306 away from the winding wheel 305, a connecting frame 308 is connected to the outer surface of the blocking block 307, and a cable clamp 309 is connected to the end of the connecting frame 308 away from the blocking block 307. The pull-out unit includes a drawer 301, a push-pull handle 302 is fixedly installed in the middle of the front of the drawer 301, a slide groove is opened in the middle of the left and right sides of the drawer 301, a guide slide rod 303 is slidably connected inside the slide groove, and a connecting rod 304 is fixedly installed in the middle of the drawer 301 near the back.

[0032] The outer surface of the connecting rod 304 is rotatably connected to the inside of the winding wheel 305 , the inside of the blocking block 307 is fixedly connected to the outer surface of the connecting rod 304 , and the guide slide rod 303 is fixedly installed on the left and right sides of the inside of the power distribution cabinet 1 .

[0033] By setting up the drawer-type structure, the drawer 301 can be pulled to drive the internal connecting rod 304 of the drawer 301 to move synchronously. Since one end of the wire connected to the component is clamped and fixed by the wire clamp 309, the winding wheel 305 can be rotated when the drawer 301 is pulled to release the excess wire, so that the drawer 301 can be pulled out to connect, install and maintain the components. When the winding wheel 305 rotates, the torsion spring 306 generates a torque, and when the drawer 301 is pushed back, the torsion spring 306 can restore its deformation, thereby driving the winding wheel 305 to rotate to wind the wire, and the wire will not be scattered.

[0034] When the drawer 301 is pulled, the drawer 301 slides on the guide slide rod 303, so that the connecting rod 304 inside the drawer 301 will move accordingly, and the connecting rod 304 will drive the winding wheel 305 to move at the same time when moving. Since the outer surface of the winding wheel 305 is wound with wires, and one end of the wires is clamped and fixed by the wire clamp 309 inside the drawer 301, when the winding wheel 305 is displaced, the remaining wires will pull the winding wheel 305 to rotate, and the remaining wires will be released while rotating. At the same time, when the winding wheel 305 rotates, the torsion spring 306 will be deformed. After the installation or maintenance of the components inside the drawer 301 is completed, when the drawer 301 is pushed back, the restoring deformation force of the torsion spring 306 can be used to drive the winding wheel 305 to rotate in the opposite direction to the above, and the released wires can be recovered while rotating, so that they can be rewound around the outer surface of the winding wheel 305, and the wires will not be scattered.

[0035] Embodiment 2:

[0036] On the basis of the first embodiment, the mobile buffer structure includes a slide cylinder 201, a slide column 202 is slidably connected to the bottom end of the slide cylinder 201, a spring 203 is fixedly connected to the bottom end of the slide cylinder 201, a connecting plate 204 is fixedly installed at the bottom end of the slide column 202, and a universal wheel 205 is installed on the bottom surface of the connecting plate 204. The top of the slide cylinder 201 is sealed and fixedly connected to the bottom surface of the power distribution cabinet 1, and the end of the spring 203 away from the slide cylinder 201 is fixedly connected to the top surface of the connecting plate 204.

[0037] The cabinet structure includes a cabinet door 101, a door handle 102 is installed at the bottom of the middle of the front of the cabinet door 101, guide sliders 103 are fixedly connected to the left and right sides of the top of the back of the cabinet door 101, and the outer surface of the guide slider 103 is slidably connected to the guide rail 104, and a fan 105 is arranged on the top of the cabinet door 101, and a ceiling 106 is arranged on the top of the fan 105. The fan 105 is installed inside the rectangular through hole opened in the middle of the top surface of the power distribution cabinet 1, the bottom end of the ceiling 106 is fixedly connected to the top surface of the power distribution cabinet 1, and two guide rails 104 are respectively installed on the top of the left and right sides of the inside of the power distribution cabinet 1.

[0038] By setting up the mobile buffer structure and the cabinet structure, and utilizing the installation of the fan 105 and the ceiling 106, the interior of the cabinet can be insulated while the fan 105 can be utilized to effectively dissipate the heat inside the power distribution cabinet 1. At the same time, by utilizing the installation of the cabinet door 101, the guide slider 103, and the guide rail 104, the cabinet door 202 can be pushed and placed horizontally on the top of the interior of the power distribution cabinet 1 after being opened, thereby not hindering the pulling and drawing of the drawer 301 and the operation of the staff. The mobile buffer structure can facilitate movement when the cabinet is moved, and the installation of the slide 201, the slide column 202, and the spring 203 can achieve a buffering and shock-absorbing effect during the movement.

[0039] When it is necessary to pull out or draw the drawer 301, the door handle 102 can be pulled to rotate the cabinet door 101 along the guide slide 103, thereby rotating to a horizontal state, and then the cabinet door 101 is pushed to be inserted into the gap between the top of the interior of the distribution cabinet 1 and the guide rail 104. The cabinet door 101 can be placed by utilizing the contact between the cabinet door 101 and the top of the interior of the distribution cabinet 1 to facilitate the staff to operate in the cabinet. By turning on the fan 105, the air flow can be effectively utilized to dissipate the heat generated by the components inside the distribution cabinet 1, so as to ensure the safety of the components inside the distribution cabinet 1 during use.
