[0002] Urban rail transit is an important component of urban public transportation systems, playing a vital role in public transportation. It features large capacity, high speed, high safety, convenient travel, low carbon emissions, environmental friendliness, and land conservation.
[0003] With the continuous development of urban rail transit technology, subway trains are becoming increasingly sophisticated, and their functions are becoming more comprehensive. At the same time, the number of electrical components on subway trains is also constantly increasing. As the control cabinet integrates most of the electrical components for the onboard equipment, the increased number of electrical components on its door panel and the optimization of its anti-fall structure have become key parameters in the design and manufacturing of the control cabinet.
[0004] Therefore, there is a need in the prior art for an electrical control cabinet for rail transit with a sliding limit structure that can prevent the door panel from falling while increasing the number of electrical components on the control cabinet door panel. Utility Model Content
[0005] The purpose of this invention is to provide an electrical control cabinet for rail transit with a sliding door limiting structure. This structure holds the opened cabinet door in place, preventing it from falling or deforming. This sliding limiting structure has the advantages of simple structure and low manufacturing cost.
[0006] An electrical control cabinet for rail transit with a sliding limit structure for the cabinet door includes an electrical control cabinet body, a cabinet door is hinged to the electrical control cabinet body, and a rotating component is provided at the lower part of the opening side of the cabinet door. The rotating component cooperates with the sliding limit structure located next to the electrical control cabinet to hold the cabinet door open and prevent the cabinet door from sinking and deforming.
[0007] Furthermore, the rotating component is a bearing, which is fixedly connected to the cabinet door via a shaft.
[0008] Furthermore, the sliding limiting structure is fixedly connected to the ground next to the electrical control cabinet body or fixedly connected to the electrical control cabinet body through a frame.
[0009] Furthermore, the sliding limiting structure includes a locking stop and at least one guide frame fixedly connected to the locking stop, wherein the locking stop is a hollow strip-shaped tube with a rectangular cross-section; the guide frame has an inverted L-shaped structure and has a guiding part and a holding part.
[0010] Furthermore, the guide part is a guide with a beveled top that is fixedly connected to the inverted L-shaped structure, or a chamfer set on the outside of the right angle of the inverted L-shaped structure.
[0011] Furthermore, a rubber layer is applied to the support portion.
[0012] Furthermore, the number of guide frames corresponds to the number of cabinet doors of the electrical control cabinet.
[0013] Furthermore, a receiving hole adapted to the rotating component is provided on one side of the locking stop.
[0014] Furthermore, the locking stop cooperates with at least one door lock installed on the cabinet door to limit the position of the cabinet door after it is opened.
[0015] Furthermore, a receiving hole adapted to the rotating component is provided on one side of the locking stop.
[0016] Furthermore, the locking stop cooperates with at least one door lock installed on the cabinet door to limit the position of the cabinet door after it is opened.
[0017] This utility model can bring the following beneficial effects:
[0018] The present invention, which adopts the above structure, is simple in structure, low in cost, and easy to install, making it suitable for retrofitting existing electrical control cabinets for rail transit. The door panel opens and closes smoothly, avoiding difficulties in opening and closing the door panel due to its own weight and preventing damage to the hinges. It is convenient for customers to use and has low maintenance costs. Attached Figure Description

[0023] like Figure 1 and Figure 2As shown, an electrical control cabinet for rail transit with a sliding limit structure for the cabinet door includes an electrical control cabinet body. A cabinet door 1 is hinged to the electrical control cabinet body. A rotating part 2 is provided at the lower part of the opening side of the cabinet door 1. The rotating part 2 cooperates with the sliding limit structure 3 located on the side of the electrical control cabinet. After the cabinet door 1 is opened, the cabinet door 1 is held up to prevent the cabinet door 1 from sinking and deforming.
[0024] Among them, the rotating component 2 is a bearing, which is fixedly connected to the cabinet door 1 via a shaft;
[0025] Among them, the sliding limit structure 3 can be fixed to the ground next to the electrical control cabinet body, or it can be like... Figure 3 The structure shown is fixedly connected to the electrical control cabinet body via frame 5. Specifically, the sliding limit structure 3 includes a locking stop 31 and at least one guide frame 32 fixedly connected to the locking stop 31. The locking stop 31 is a hollow strip-shaped tube with a rectangular cross-section. The guide frame 32 has an inverted L-shaped structure and has a guiding part 321 and a holding part 322.
[0026] The guide section 321 can be Figure 2 The guide member shown is a door frame-like structure with a beveled top, which is fixedly connected to the inverted L-shaped structure. Alternatively, it can be a chamfered structure (not shown in the figure) provided on the right-angled outside of the inverted L-shaped structure. Under the guidance of the guide 321, the rotating member 2 can smoothly enter the holding part 322. In order to reduce the wear between the rotating member 2 and the holding part 322, a rubber layer is also applied to the holding part 322 in this embodiment.
[0027] It should be noted that the number of guide frames 32 corresponds to the number of cabinet doors 1 of the electrical control cabinet, that is, all cabinet doors 1 can be held up by a sliding limit structure 3;
[0028] In this embodiment, a receiving hole 311 adapted to the rotating member 2 is provided on one side of the locking stop 31. The receiving hole 311 can partially accommodate the rotating member 2. The advantage of this arrangement is that the length of the holding part 322 can be shortened.
[0029] In this embodiment, the lock stop 31 cooperates with at least one door lock 4 provided on the cabinet door 1. The door lock 4 specifically includes a rotating shaft, a toggle switch provided at one end of the rotating shaft, and a stop plate provided at the other end of the rotating shaft. The rotating shaft can be rotated by the toggle switch to complete the contact or disengagement between the stop plate and the lock stop 31, so as to limit the position of the cabinet door 1 when the operator opens the cabinet door 1 to install electrical components.
[0030] The above description is only a preferred embodiment of the present utility model. Any equivalent substitutions and modifications made by those skilled in the art without departing from the guidance of the present utility model shall be deemed to fall within the protection scope of the present utility model.
