Description

Technical Field

[0001] This utility model relates to the technical field of low-voltage switchgear equipment, and in particular to a low-voltage withdrawable switchgear with good protection. Background Technology

[0002] Low-voltage switchgear typically consists of components such as circuit breakers, contactors, relays, instruments, control buttons, and indicator lights. Existing low-voltage switchgear, for ease of installation and production, primarily uses rectangular cabinet structures. During use, it is placed directly on the workshop floor, relying on its own weight for stability. However, when the top drawer of a drawer-type switchgear is opened, improper operation due to the angle of force applied could cause the switchgear to tilt and collapse, leading to loose wiring or even fire hazards, threatening production and personal safety.

[0003] Publication (Announcement) No. CN221900447U discloses a safety-type protective low-voltage switchgear, including a switchgear cabinet. The switchgear cabinet is a rectangular box structure with several pull-out cabinets evenly arranged from top to bottom on the switchgear cabinet. A pair of parallel support columns are provided on the top of the switchgear cabinet. A pair of sliding grooves are provided on the pair of support columns. This utility model relates to the field of low-voltage switchgear technology. This safety-type protective low-voltage switchgear addresses the problem of easy tilting when pulling out pull-out switchgear by setting up a quick-release snap-fit ​​structure, which effectively prevents the low-voltage switchgear from tilting due to outward pulling force, thus preventing safety hazards. It also allows for quick installation of the switchgear as needed, and can be quickly unlocked and moved in case of a dangerous situation where the switchgear is threatened. It has good deployment flexibility. The quick-release snap-fit ​​structure on the top can also effectively provide installation space for side-by-side arrangement of switchgear.

[0004] While the above solution can avoid the problem of easy tilting when the switch cabinet is pulled out, the cabinet locking structure requires gear transmission components, telescopic rods, adjusting bolts and other structural components. The equipment safety locking structure is complex and costly to manufacture. In addition, the fixed position of the fixing components that cooperate with the locking structure is generally not very effective. Therefore, we propose a low-voltage withdrawable switch cabinet with good protection. Utility Model Content

[0005] The main purpose of this utility model is to provide a low-voltage withdrawable switchgear with good protection. By setting up assembly units and limiting components, it solves the problems of complex and costly manufacturing of equipment safety locking structures, and the general applicability of fixing components that are used in conjunction with locking structures.

[0006] To solve the above technical problems, the present utility model is achieved through the following technical solutions: A low-voltage draw-out switchgear with good protection includes a switchgear body and a drawer movably arranged on the switchgear body, and further includes: an assembly unit and a limiting component arranged on the switchgear body;

The bidirectional screw rod is movably embedded and installed on one side surface of the assembly box. There are two bearing plates in total, which respectively correspond to and cooperate with the symmetrically arranged positive and negative two sections of threads on the bidirectional screw rod. The bearing plate is in a "convex" shape. The two plug-in plates are respectively fixedly arranged on the opposite two side surfaces of the two bearing plates. The plug-in plate penetrates through the activity through groove and the limiting through groove.

The double-acting screw is held and rotated in both directions outside the assembly box. The two supporting plates, which are threaded to the double-acting screw and are also "U"-shaped, can move relative to each other inside the assembly box under the force. The two plug-in plates can be adjusted by the support plates. After the two plug-in plates are pulled apart and moved out of the assembly box through the movable through slot, they can be inserted into the limiting through slot on the supporting frame plate. The main body of the switch cabinet and the assembly box are then safely limited on the limiting frame plate. After the two plug-in plates are moved back into the assembly box, the main body of the switch cabinet and the assembly box can be detached from the limiting component.
