Description

Technical Field

[0001] The utility model relates to the technical field of high and low voltage switch cabinets, in particular to a switch cabinet with a locking structure. Background Art

[0002] High and low voltage switchgear is widely used in power systems. It is one of the important equipment to ensure the safe and stable operation of power systems. High and low voltage switchgear consists of main components such as cabinet and circuit breaker, and has multiple functions such as control, protection, monitoring and measurement. In modern power systems, high and low voltage switchgear plays a vital role in ensuring the safe and stable operation of power systems.

[0003] At present, in the prior art, a Chinese patent with announcement number CN207925938U discloses a high and low voltage switch cabinet, which is provided with a cabinet top through the top of the high and low voltage switch cabinet. The cabinet top adopts an isosceles triangle design, which has a certain sliding effect, prevents objects from pressing on the box body, and can also prevent the accumulation of rain and snow. However, in actual use, the high and low voltage switch cabinet lacks a door lock locking device, so anyone can easily open the high and low voltage switch cabinet, which increases the risk of electric shock or misoperation of the operator. At the same time, this also makes it possible for other personnel to contact the equipment in the cabinet, thereby causing equipment damage or personal injury. In view of this, we propose a switch cabinet with a locking structure. Utility Model Content

[0006] A connecting rod, the handle portion of the door lock is fixedly connected with the connecting rod, and the connecting rod passes through the outer wall of the high-voltage cabinet door;

[0007] A rotating convex plate is fixedly connected to one end of the connecting rod away from the door lock handle portion.

[0008] Preferably, a sliding groove is provided on the surface of the rotating convex plate, and two groups of the sliding grooves are provided. The arc-shaped setting of the sliding groove facilitates the subsequent expansion, contraction and locking operations.

[0009] Preferably, a sliding column is slidably connected in the sliding groove, and a telescopic positioning plate is fixedly connected to the outer wall of the sliding column. The sliding column slides along the sliding groove to drive the telescopic positioning plate to stretch.

[0010] Preferably, two groups of the sliding columns and telescopic positioning plates are provided, and the two groups move towards each other to drive the switch cabinet body to realize the locking function.

[0011] Preferably, the telescopic positioning plate is slidably connected in a square groove opened in the mounting shell, and the square groove is symmetrical with the center of the rotating convex plate. The setting of the square groove prevents the sliding column from driving the telescopic positioning plate to perform rotational and stretching movement, so that the telescopic positioning plate performs linear reciprocating movement in the square groove.

[0012] Preferably, the mounting shell is fixedly connected to the inner wall of the switch cabinet body, and the connecting rod passes through the outer wall of the mounting shell and is fixedly connected to the rotating convex plate. On the one hand, the mounting shell protects the movable extension and retraction of the telescopic positioning plate, and on the other hand, increases the friction with the rotating convex plate to prevent rotation deviation.

[0013] The utility model provides a switch cabinet with a locking structure. It has the following beneficial effects:

[0014] (1) The switch cabinet with a locking structure is provided with a rotating locking device. By rotating the handle part of the door lock, after rotating 90 degrees, the connecting rod drives the rotating convex plate to rotate, and the sliding column in the sliding groove slides along the arc-shaped surface of the sliding groove, driving the extension movement of the telescopic positioning plate. The square groove on the mounting shell allows the telescopic positioning plate to perform linear reciprocating movement in the square groove. After the telescopic positioning plate is unfolded, it is locked with the switch cabinet body, which can ensure the normal operation of the high and low voltage switch cabinets and the safety of operators, thereby improving the safety and practicality of the high and low voltage switch cabinets.

[0015] (2) The switch cabinet with a locking structure is provided with a mounting shell. The mounting shell protects the telescopic positioning plate from moving and retracting, and increases the friction with the rotating convex plate to prevent rotation deviation.
