Description

Technical Field

[0001] The utility model relates to the technical field of installation of electrical components of electric cabinets, in particular to an installation mechanism for electrical components of low-voltage distribution cabinets. Background Art

[0002] High and low voltage distribution cabinets are distribution equipment used for power distribution, control, metering and cable connection in power supply systems. Generally, power supply bureaus and substations use high voltage switch cabinets, which are then stepped down by transformers and led to low voltage distribution cabinets. The low voltage distribution cabinets are then led to the distribution boards, control boxes and switch boxes of various power users. The equipment in the cabinets is a distribution device that is assembled into one by some switches, circuit breakers, fuses, buttons, indicator lights, meters, wires and other protective devices to meet the design functional requirements.

[0003] However, in the existing technology, the high and low voltage distribution cabinets in the existing technology are generally customized according to the electrical equipment, and the electrical component mounting structure in the distribution cabinet is fixed to the inside of the distribution cabinet by welding or screws, so that the electrical components are not convenient to remove from the distribution cabinet after installation and maintenance. At the same time, different types of electrical components need to be installed in the existing distribution cabinet, but the electrical component mounting plates in the existing distribution cabinet are relatively simple, which results in that only one type of electrical components can be installed in the distribution cabinet.

[0004] Therefore, we need a mounting mechanism for electrical components of a low-voltage distribution cabinet, which solves the installation problem of electrical components of the existing low-voltage distribution cabinet and can also realize the installation of electrical components of different models in the distribution cabinet. Utility Model Content

[0005] The purpose of the present invention is to provide an installation mechanism for electrical components of a low-voltage distribution cabinet to solve the installation problem of electrical components of the existing low-voltage distribution cabinet raised in the above background technology, and also to realize the installation of electrical components of different models in the distribution cabinet.

[0006] To achieve the above object, the present utility model provides the following technical solutions: An installation mechanism for electrical components of a low-voltage power distribution cabinet, including an installation plate. A guide block is fixedly connected to the surface of the side plate of the installation plate, and the surface of the guide block is movably connected to the surface of a guide groove. The guide groove is opened on the inner surface of the side plate of the low-voltage power distribution cabinet body. A limiting card slot is opened on the side surface of the installation plate, and the surface of the limiting card slot is fitted with the surface of a rack.

A through hole is opened inside the limiting card frame, and the end of a rotating pin is fixedly connected to the surface of the through hole. The surface of the rotating pin is rotatably connected to the inside of a locking card plate. The tooth hook end of the locking card plate is clamped with the tooth of the rack. The end of a spring is fixedly connected to the inner surface of the locking card plate, and the other end of the spring abuts against the outer surface of the limiting card frame.

[0007] Preferably, the limiting card slot completely penetrates through the top surface of the installation plate, and the width dimension of the limiting card slot is equal to the width dimension of the rack.

[0008] Preferably, the limiting card frame is arranged in a "C" shape, and the inner surface width dimension of the limiting card frame is equal to the width dimension of the rack.

[0009] Preferably, a groove is opened on the top surface of the installation plate, the end of a positioning rod is fixedly connected to the surface of the groove, the surface of the positioning rod is rotatably connected to the inside of a folding plate, an installation bolt hole is opened on the surface of the folding plate, and a buckle groove is opened at the end of the folding plate.

[0010] Preferably, a limiting card hole is opened on the side surface of the folding plate, a support plate is inserted into the surface of the limiting card hole, the bottom end of the support plate abuts against the top surface of the installation plate, and the cross section of the support plate is arranged in an "L" shape.

[0011] Preferably, the installation bolt hole completely penetrates through the surface of the folding plate, the installation bolt holes are provided in several numbers, and several installation bolt holes are equally spaced on the surface of the folding plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are: by movably connecting the surface of the guide block to the surface of the guide groove, and fixing the surface of the guide block to the end face of the mounting plate, the mounting plate is guided to move up and down inside the low-voltage distribution cabinet body, so that the position of the mounting plate inside the low-voltage distribution cabinet body can be adjusted according to the size of different electrical components, and bolt holes are opened on the top surface of the mounting plate, so that the electrical components can be conveniently fixed on the top surface of the mounting plate through the bolt holes. When the tooth hook end of the rotating pin engages the teeth of the rack, the mounting plate is firmly installed at a height inside the low-voltage distribution cabinet body. When other types of electrical components need to be installed, the folding plate can be flipped and folded out from the surface of the groove. By opening mounting bolt holes on the surface of the folding plate, other types of electrical components can be conveniently positioned and installed through the folding plate. This further solves the installation problem of electrical components in existing low-voltage distribution cabinets, and also enables different types of electrical components to be installed in the distribution cabinet.
