Description

Technical Field

[0001] The utility model relates to a high-speed train, in particular to a plug-type sliding door cover plate of the high-speed train. Background Art

[0002] The high-speed train door cover is installed next to the train's sliding door, between the vehicle floor and the flat roof, and is mainly used to cover the door mechanism of the sliding door.

[0003] When inspecting the door mechanism components of the existing plug-type sliding door cover plate structure, the entire door cover plate must be removed for inspection or maintenance, which results in complicated disassembly and assembly, a large workload for maintenance, low efficiency, and high labor costs. In addition, repeated disassembly and assembly causes the assembly gap between the plug-type sliding door cover plate and the wall to become larger and uneven, affecting the firmness and appearance. Summary of the invention

[0004] In order to solve the above problems, the utility model provides a high-speed train door cover plate with an integrated inspection door, which can be inspected without removing the door cover plate as a whole.

[0005] The high-speed train door cover plate with integrated inspection door described in the utility model comprises a cover plate body, an inspection door, a hinge, a clamping lock and a lock tongue clamping plate; a plurality of hinges are arranged at intervals along the height direction between the cover plate body and the inspection door, and the two ends of the hinges are respectively fixed on the inspection door and the cover plate body; a plurality of clamping locks are arranged at intervals along the height direction near the cover plate body on the inspection door, and a plurality of lock tongue clamping plates are correspondingly arranged on the cover plate body at the same height as the clamping locks; the lock tongue clamping plate extends out of the cover plate body, and the lock tongue of the clamping lock is located on the inner side of the lock tongue clamping plate after being extended.

[0006] Furthermore, there are three locking tongue pressure plates and three hinges.

[0007] Furthermore, the three hinges are located at both ends and the upper middle portion of the cover plate body and the inspection door, and the compression lock is located between the hinges.

[0008] Furthermore, the compression lock is a compression lock controlled by four-corner keys.

[0009] Furthermore, the inspection door is an irregular polygonal door body.

[0010] The high-speed train door cover plate with integrated maintenance door described in the utility model can be opened or closed by rotating the compression lock with a four-corner key, and then the maintenance door can be opened or closed to facilitate maintenance work. There is no need to remove the entire cover plate, which reduces the disassembly and installation time, greatly improves the maintenance efficiency, and also reduces the maintenance labor cost. At the same time, it also avoids the unsightly or unreliable problems such as increased assembly gap due to repeated installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Combine the following Figures 1 to 3 The high-speed train door cover plate of the integrated inspection door of the utility model is described in detail.

[0017] like Figures 1 to 3 As shown, the high-speed train door cover plate with integrated inspection door of the utility model comprises a cover plate body 1, an inspection door 2, a hinge 3, a clamping lock 4, and a lock tongue pressure plate 5.

[0018] Among them, the inspection door 2 is an irregular polygonal door body.

[0019] The cover plate body 1 and the inspection door 2 are provided with three hinges 3 at intervals along the height direction, and the two ends of the hinges 3 are respectively fixed on the inspection door 1 and the cover plate body 2; the three hinges 3 are located at the two ends and the upper middle part of the cover plate body 1 and the inspection door 2.

[0020] The inspection door 2 is provided with three compression locks at intervals near the cover plate body 1 along the height direction. The compression lock 4 is located between the hinges 3 and is controlled by four-corner keys.

[0021] Correspondingly, a plurality of lock tongue pressing plates 5 are arranged on the cover plate body 1 at the same height as the compression lock 3 ; the lock tongue pressing plates 5 extend out of the cover plate body 1 , and the lock tongue of the compression lock 3 is located inside the lock tongue pressing plates 5 after being extended.

[0022] The high-speed train door cover plate with integrated maintenance door described in the utility model can be opened or closed by rotating the compression lock with a four-corner key, and then the maintenance door can be opened or closed to facilitate maintenance work. There is no need to remove the entire cover plate, which reduces the disassembly and installation time, greatly improves the maintenance efficiency, and also reduces the maintenance labor cost. At the same time, it also avoids the unsightly or unreliable problems such as increased assembly gap due to repeated installation.

[0023] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
