Description

Technical Field

[0001] The utility model relates to the technical field of distribution cabinets, in particular to a draw - out type high - low voltage distribution cabinet. Background Technique

[0002] As the name implies, high - low voltage distribution cabinets are power distribution equipment used for power distribution, control, metering, and connecting cables in the power supply system. Generally, high - voltage switch cabinets are used in power supply bureaus and substations. Then, after stepping down the voltage through a transformer, the low - voltage side is led out to the low - voltage distribution cabinet, and the low - voltage distribution cabinet is then connected to each power - consuming distribution board, control box, and switch box. Inside, it is a power distribution device that assembles some switches, circuit breakers, fuses, buttons, indicator lights, meters, wires, and other protection devices to meet the design function requirements.

[0003] Usually, some electronic components inside high - low voltage distribution cabinets are directly fixedly installed on the internal mounting panel. When repairing a certain component, it is necessary to disassemble it and then perform the repair, which is rather troublesome. The internal repair space is small, time - consuming and laborious. Therefore, it does not meet the existing requirements. For this reason, we propose a draw - out type high - low voltage distribution cabinet. Content of the Utility Model

[0020] 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.

[0021] Example 1

[0022] See also Figures 1-4, A draw - out type high - and - low - voltage switchgear cabinet, including a high - and - low - voltage switchgear cabinet body 1 and a cabinet door 2 hinged on the high - and - low - voltage switchgear cabinet body 1. A plurality of mounting panels 6 are fixedly installed on the inner cavity side wall of the high - and - low - voltage switchgear cabinet body 1. A rectangular frame 3 is slidably arranged between the plurality of mounting panels 6. Electronic components 4 are arranged on the rectangular frame 3. A moving component 5 for allowing the rectangular frame 3 to move is arranged between the inner cavity side wall of the high - and - low - voltage switchgear cabinet body 1 and the corresponding rectangular frame 3.

[0023] The moving component 5 includes a connecting cylinder 51 fixedly installed on the inner cavity side wall of the high - and - low - voltage switchgear cabinet body 1 and a movable sleeve 52 fixedly installed on the side wall of the rectangular frame 3. The movable sleeve 52 is slidably arranged on the connecting cylinder 51. Two limiting columns 57 are slidably arranged on the movable sleeve 52. Two limiting holes 58 are opened on the side wall of the connecting cylinder 51. The limiting columns 57 are inserted into the limiting holes 58. A resisting panel 59 is slidably arranged on the inner cavity side wall of the connecting cylinder 51. A first spring 501 is fixedly connected between the resisting panel 59 and the inner cavity side wall of the connecting cylinder 51. With the cooperation of the first spring 501 and the resisting panel 59, when the rectangular frame 3 is not limited, the resisting panel 59 can push the movable sleeve 52 and the rectangular frame 3.

[0024] A connecting rod 53 is slidably arranged on the rectangular frame 3. The connecting rod 53 is inserted into the movable sleeve 52. A hinge rod 56 is hingedly arranged between the connecting rod 53 and the limiting column 57.

[0025] A connecting panel 54 is fixedly installed on the inner cavity side wall of the movable sleeve 52. The connecting rod 53 is slidably arranged on the connecting panel 54. Through the arrangement of the connecting panel 54, the connecting rod 53 can slide stably.

[0026] A second spring 55 is sleeved on the connecting rod 53. The two ends of the second spring 55 are respectively fixedly connected with the side wall of the connecting panel 54 and the axial side wall of the connecting rod 53. In the initial state, the second spring 55 is in a compressed state.

[0027] A limiting component 7 is arranged between the rectangular frame 3 and the connecting rod 53;

[0028] The limiting component 7 includes a limiting panel 71 fixedly installed at one end of the connecting rod 53 and a threaded column 72 threaded on the limiting panel 71. The threaded column 72 is threaded on the rectangular frame 3. Through the arrangement of the threaded column 72, the connecting rod 53 can be limited on the rectangular frame 3.

[0029] In this embodiment, after the electronic components 4 on the rectangular frame 3 are installed, the rectangular frame 3 is pushed, so that the movable sleeve 52 on the rectangular frame 3 slides along the connecting cylinder 51. At this time, the movable sleeve 52 pushes the abutting panel 59 to slide along the inner cavity side wall of the connecting cylinder 51, and the connecting cylinder 51 compresses the first spring 501 until the limiting column 57 on the movable sleeve 52 is displaced to a position corresponding to the limiting hole 58. At this time, the threaded column 72 is rotated to separate the threaded column 72 from the rectangular frame 3. At this time, the connecting rod 53 is subjected to the elastic force of the second spring 55, and it will slide along the connecting panel 54 close to one end of the limiting column 57. Through the arrangement of the hinge rod 56, the connecting rod 53 will squeeze the limiting column 57, and the limiting column 57 will slide along the limiting hole 58, so as to limit the rectangular frame 3 and the high and low voltage power distribution cabinet body 1.

[0030] When the electronic components 4 on the rectangular frame 3 need to be repaired, the threaded column 72 is rotated to separate the threaded column 72 from the rectangular frame 3. At this time, the connecting rod 53 is pulled. The connecting rod 53 pulls the limiting column 57 through the hinge rod 56, so that the limiting column 57 is separated from the limiting hole 58. At this time, through the arrangement of the first spring 501 and the abutting panel 59, the movable sleeve 52 can quickly return to its initial position. At this time, the rectangular frame 3 and the high and low voltage power distribution cabinet body 1 are released from the limit, and the rectangular frame 3 can be pulled to slide along the mounting panel 6, so that the electronic components 4 can be repaired without being disassembled, which saves time and effort, is simple to operate and convenient to use.
