Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, specifically a low-voltage switchgear that is easy to maintain. Background Technology

[0002] A switchgear is an electrical device. External lines first enter the main control switch inside the cabinet, and then enter the branch control switches. Each branch is set according to its needs, such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. Some also have high-voltage and low-voltage switchgear, and have high-voltage busbars, such as power plants. Some also have underfrequency load shedding to protect the main equipment.

[0003] Currently, when repairing switch cabinets, the pull-out cabinets need to be moved to a table for maintenance. This not only requires moving the pull-out cabinets a long distance but also affects the maintenance progress. Utility Model Content

[0004] The purpose of this utility model is to provide a low-voltage switchgear that is easy to maintain, in order to solve the problem mentioned in the background art that the current switchgear requires the pull-out cabinet to be placed on a table for maintenance, which not only requires moving the pull-out cabinet a long distance, but also affects the maintenance progress.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-voltage switchgear that is easy to maintain, comprising a switchgear and a pull-out cabinet, wherein the pull-out cabinet is provided inside the switchgear, and the low-voltage switchgear that is easy to maintain further comprises: a support member slidably disposed on the front surface of the switchgear; and a limiting member slidably disposed at the bottom end of the support member; wherein the support member is used to support the pull-out cabinet, and the limiting member is used to limit the support member.

[0006] Preferably, the front surface of the switch cabinet is provided with slide rails on the left and right sides, and limit holes are provided in the slide rails.

[0007] Preferably, in order to support and fix the pull-out cabinet, the front surface of the switch cabinet is provided with a support member;

[0008] The pull plate drives the slide rod forward. The slide rod's forward movement causes the slide groove to move inward through the inclined groove on its back. The slide groove causes the first limiting rod to move inward. The inward movement of the first limiting rod releases the limitation on the first slider. Then, the first slider moves upward, causing the support plate to move upward. When the support plate moves to the appropriate position, it is rotated upward. The support rod limits the support plate through the support plate. Then, the pull-out cabinet is pulled forward to the top of the support plate for maintenance.

[0009] Preferably, a first spring is provided inside the groove and the first slider.

[0010] Preferably, the bottom end of the slide bar is provided with a sloping groove.

[0011] Preferably, in order to limit and fix the supporting member, a limiting member is provided at the bottom end of the supporting member;

[0012] The support block drives one end of the support rod to move upward, and the other end of the support rod drives the second slider to move upward. When the second slider moves to the appropriate position, the insertion rod is released, and the spring on the outer wall of the insertion rod drives the insertion rod to move backward to reset. The insertion rod drives the pressing block to move backward, and the pressing block moves backward, causing the pressure block to move left and right. The pressure block drives the second limiting rod to move left and right, and the second limiting rod moves left and right to limit the second slider. The second slider limits the support rod, and the support rod limits the support plate through the support plate.

[0013] Preferably, the outer wall of the insertion rod is provided with a second spring.

[0014] Preferably, a third spring is provided inside the pressure block.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This easy-to-maintain low-voltage switchgear achieves the limiting and fixing of the first slider through the cooperation of the sliding rod, pull plate, slider and first limiting rod, thereby limiting and fixing the support plate; through the cooperation of the insertion rod, pressing block, pressure block and second limiting rod, the limiting and fixing of the second slider is achieved; through the cooperation of the second slider and support rod, the support block is supported and limited, thereby supporting and limiting the other end of the support plate. Through the cooperation of the above components, it is convenient for maintenance personnel to maintain the pull-out cabinet. Attached Figure Description

[0029] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0030] When the easily maintainable low-voltage switchgear needs maintenance, the user first moves the pull plate 303 in the support member 3 forward. The pull plate 303 drives the slide rod 302 forward. The slide rod 302 moves forward and drives the slide groove 305 inward through the inclined groove on the back of the slide rod 302. The slide groove 305 drives the first limiting rod 304 inward. The inward movement of the first limiting rod 304 releases the limitation on the first slider 301. Then, the first slider 301 is moved upward. The first slider 301 drives the support plate 306 upward. When the support plate 306 moves to the appropriate position, the support plate 306 is rotated upward. Then, the user pulls the insertion rod 402 in the limiting member 4 forward. The insertion rod 402 drives the pressing block 403 forward. The forward movement of the pressing block 403 releases the limitation on the pressure block 405. The third spring inside the pressure block 405 drives the pressure block 405 inward. The pressure block 405 then moves the second limiting rod 404 inward. The second limiting rod 404 moves inward to release the limitation on the second slider 401. The support plate 306 drives the support block 407 to rotate upward. The support block 407 drives one end of the support rod 406 to move upward. The other end of the support rod 406 drives the second slider 401 to move upward. When the second slider 401 moves to the appropriate position, the insertion rod 402 is released. The second spring on the outer wall of the insertion rod 402 drives the insertion rod 402 to move backward to reset. The insertion rod 402 drives the pressing block 403 to move backward. The pressing block 403 moves backward to drive the pressing block 405 to move left and right. The pressing block 405 drives the second limiting rod 404 to move left and right. The left and right movement of the second limiting rod 404 limits the second slider 401. The second slider 401 limits the support rod 406. The support rod 406 limits the support plate 306 through the support plate 407. Then, the drawer cabinet 2 is pulled forward to move forward to the top of the support plate 306 for maintenance.
