Description

Technical Field

[0001] This utility model relates to the field of garbage bin tray technology, specifically a garbage bin tray structure for a washroom in a rail vehicle. Background Technology

[0002] With the rapid development of rail transit, passengers' demands for travel experience are increasing. The cleanliness, hygiene, aesthetics, and ease of maintenance of the vehicle's interior environment have become important indicators for measuring vehicle quality. As an essential public health facility within the carriage, the rationality of the design of the trash can directly affects the hygiene of the carriage environment and the maintenance efficiency of the crew. In existing technology, rail vehicle trash cans typically have a tray inside. Its main function is to support and secure the container inside for holding trash bags. When the trash bags break and leak, it is convenient for cleaning staff to directly remove the container for cleaning, preventing the accumulation of pollutants. However, existing trash can tray structures still have some problems: during use, it is difficult to effectively secure internal containers of different sizes. The containers inevitably move during vehicle operation, which can cause collisions between the container and the tray structure, generating noise and negatively impacting the passenger environment. Furthermore, the movement of the container can cause the trash inside the bags to move synchronously, potentially increasing the risk of the trash bags breaking. Utility Model Content

[0003] The purpose of this utility model is to provide a trash can holder structure for the washroom of a rail vehicle, in order to solve the following problems of the trash can holder structure mentioned in the background art: During the use of trash can holders on the market, it is difficult to effectively fix the internal boxes of different sizes. During the operation of the vehicle, the boxes will inevitably move, which will cause the boxes and the holder structure to collide, thereby generating noise and having an adverse impact on the riding environment. In addition, the movement of the boxes will cause the garbage in the internal garbage bags to move synchronously, which may increase the risk of the garbage bags breaking.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a trash can holder structure for a washroom in a rail vehicle, comprising:

[0005] The frame also includes: a support cover fixedly connected to the bottom of the frame, a garbage bin shell placed inside the support cover, horizontal loading platforms slidably extending through both sides of the top of the frame, and a transmission mechanism movably installed on the inner wall of the loading platform. The transmission mechanism includes a rotating block, both ends of the rotating shaft of the rotating block being rotatably embedded in the inner wall of the loading platform. Symmetrically distributed pressure heads are slidably inserted into the side wall of the loading platform, with the ends of the pressure heads facing the inner side of the frame.

[0006] Preferably, a horizontal guide rail is fixedly installed on the outer wall of the housing. The middle part of the drive frame is slidably sleeved on the side of the guide rail away from the housing, and a handle is provided on the top of the drive frame. A one-way rack is fixedly embedded in the mounting groove at the top of the guide rail, and a limiting tooth is fitted on the teeth of the one-way rack to form a one-way limiting structure. The top of the limiting tooth is fitted into the inner side of the drive frame, and the upper end face of the limiting tooth and the top of the inner wall of the drive frame are elastically connected by a spring. A control rod is fixedly connected to the top of the limiting tooth, and the control rod is slidably installed through the upper part of the drive frame, so that the control rod can drive the limiting tooth to move.
