[0025] A retractable small table in a subway driver's cab, such as Figures 1 to 4 As shown, it includes a loading plate 1, and a rotating shaft 2 is symmetrically arranged at both ends of the loading plate. The rotating shaft on each side is rotatably mounted on a fixed seat 3, and a locking mechanism 4 is arranged on one fixed seat, and a hook 5 is arranged on the fixed seat on the other side; two storage barrels 6 are arranged on the upper side of the loading plate, and the upper end of the storage barrel is open 7, and the lower end is provided with a connecting portion 8, and a support plate 9 is arranged in the storage barrel, and a plurality of through holes 10 are arranged on the support plate, and the open end is fixed to the loading plate, and a liquid storage box 11 is detachably installed on the connecting portion; the locking mechanism includes a bracket 12 installed on the upper side of the fixed seat, and an adjustment component is arranged on the bracket, and a fixed plate 13 is arranged on the loading plate, and a limit hole is arranged on the fixed plate corresponding to the adjustment component. When a water cup or other items are placed in the storage barrel, even if liquid is spilled, the liquid will flow into the liquid storage box along the through holes of the support plate, and will not cause pollution in the upper space of the support plate of the storage barrel.

[0026] The adjustment assembly includes a nut 14 fixed to the bracket and an adjustment rod 15 screwed on the nut, and a plug 16 is provided on the side of the adjustment rod facing the carrier. When the carrier is laid flat, the adjustment rod can be screwed to insert the adjustment rod plug into the limit hole of the fixed plate, so that the carrier is in a horizontal state and the stability is guaranteed. When the carrier needs to be stored, the adjustment rod only needs to be screwed to withdraw the plug from the limit hole of the fixed plate, and the carrier can be flipped to make the carrier stand upright, reducing the space occupied. At this time, in order to ensure the stability of the carrier in the stored state, the adjustment rod can be screwed to extend the adjustment rod to the side of the carrier and abut against the lower surface of the carrier, that is, when the carrier is in the upright state, the front end of the adjustment rod blocks the side wall of the carrier to ensure that the carrier will not flip back to the original position (horizontal position). Through the locking mechanism, the carrier can be switched between the use state and the storage state. The carrier has good stability and will not shake violently when the train is running.

[0027] The adjustment rod adopts a screw with a full thread structure. In order to facilitate the screwing of the adjustment rod, an operating handle 17 is provided at the end of the adjustment rod different from the plug. A connecting section 18 is provided at the upper end of the liquid storage box, and the connecting section is threadedly connected to the connecting part. As an example, the outer wall of the connecting section is provided with an external thread structure, and the inner wall of the connecting part is provided with an internal thread structure matching the external thread structure. Anti-slip textures can be provided on the outer wall of the liquid storage box to facilitate the installation and disassembly of the liquid storage box and the pouring of the liquid accumulated inside.

[0028] The invention has a simple structure. The loading plate, storage tube and hook are all made of stainless steel, which is clean and tidy and easy to clean. When in use, the loading plate can be laid flat, and items such as water cups and walkie-talkies can be placed in the storage tube. The support plate can effectively play a supporting role, and the support plate divides the lower and upper parts of the storage tube into two spaces. The spilled liquid will flow through the through holes of the support plate to the liquid storage box. The space above the support plate remains clean. The hook can be used to hook items such as crew bags. When the small table is not needed, the loading plate can be locked upright. This design effectively improves the aesthetics and practicality of the open driver's cab, and the small table structure can be kept stable in both the use state and the storage state.
