Description

Technical Field

[0001] This utility model relates to a novel tea table for high-speed trains, belonging to the technical field of high-speed train equipment. Background Technology

[0002] With my country's rapid economic development, the high-speed rail industry has ushered in a new leapfrog development, and people's willingness to travel by high-speed rail is gradually increasing. Seats are the direct interface between passengers and high-speed trains; therefore, end tables need to be installed on the walls at both ends of the carriage and fixed to the end walls.

[0003] Currently, the tea tables at the ends of high-speed trains have the following problems: their load-bearing capacity is limited, and they automatically unload after reaching a certain load, causing damage to passengers' belongings and leading to frequent complaints. Furthermore, their load-bearing capacity changes with use, often resulting in rework and repairs. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of tea table for high-speed trains, which has a large load-bearing capacity and does not require overload protection, thus solving the above-mentioned problems in the background art.

[0005] The technical solution of this utility model is:

[0006] A novel tea table for high-speed trains includes a tea tabletop, a connecting rod, a support plate, a first rotating shaft, a second rotating shaft, a third rotating shaft, a fourth rotating shaft, a mounting base, and a pressure plate. The mounting base and the pressure plate are respectively fixed to the wall panel, with the mounting base located above the pressure plate. One end of the tea tabletop is connected to the mounting base via the fourth rotating shaft, and the other end of the tea tabletop is connected to the upper part of the support plate via the second rotating shaft. The lower end of the support plate overlaps the pressure plate. One end of the connecting rod is connected to the mounting base via the first rotating shaft, and the other end of the connecting rod is connected to the support plate via the third rotating shaft.

[0007] Furthermore, the surface at the lower end of the support plate that contacts the pressure plate is an arc-shaped surface.

[0008] Furthermore, the lower end of the support plate is provided with a locking mechanism that cooperates with the tea tabletop.

[0009] Furthermore, the locking mechanism includes a locking ball, a spring, and a slot. The lower end of the support plate is provided with a columnar groove that cooperates with the locking ball and the spring. The spring and the locking ball are disposed in the columnar groove at the lower end of the support plate. The slot is disposed on the tea table and cooperates with the locking ball.

[0010] Furthermore, the tea tabletop, support plate, and wall panel form a right-angled triangle.

[0011] With this utility model, when the tea table is in a horizontal state, the lower end of the support plate is in contact with the pressure plate, and the tea table, support plate and wall panel form a right triangle; when the tea table is in a vertical state, the connecting rod and support plate are in contact with the tea table, triggering the locking mechanism to lock automatically.

[0012] The advantages of this utility model are: easy installation, simple and reliable structure, and large load-bearing capacity. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] See attached document Figure 1-8A novel tea table for high-speed trains includes a tea tabletop 1, a connecting rod 2, a support plate 3, a first rotating shaft 4, a second rotating shaft 5, a third rotating shaft 6, a fourth rotating shaft 7, a mounting base 8, and a pressure plate 9. The mounting base 8 and the pressure plate 9 are respectively fixed to the wall panel, with the mounting base 8 located above the pressure plate 9. One end of the tea tabletop 1 is connected to the mounting base 8 via the fourth rotating shaft 7, and the other end of the tea tabletop 1 is connected to the upper end of the support plate 3 via the second rotating shaft 5. The lower end of the support plate 3 overlaps the pressure plate 9. One end of the connecting rod 2 is connected to the mounting base 8 via the first rotating shaft 4, and the other end of the connecting rod 2 is connected to the support plate 3 via the third rotating shaft 6.

[0025] In this embodiment, refer to the appendix Figure 1-9 This new type of high-speed train tea table includes a tea tabletop 1, a connecting rod 2, a support plate 3, a first rotating shaft 4, a second rotating shaft 5, a third rotating shaft 6, a fourth rotating shaft 7, a mounting base 8, a pressure plate 9, and a locking mechanism, wherein:

[0026] The lower end of the support plate 3 has an arc-shaped surface that contacts the pressure plate 9. A columnar groove is provided on the support plate 3 near the arc-shaped surface. The locking mechanism includes a locking ball 10, a spring 11, and a slot 12. The spring 11 and the locking ball 10 are set in the columnar groove of the support plate 3, and the slot 12 is set on the tea table 1. The slot 12 cooperates with the locking ball 10.

[0027] When the locking bead 10 is subjected to a certain amount of force, it retracts into its cylindrical groove. When the force is released, it pops out under the action of the internal spring 11. When the tea table is folded up, the locking bead 10 collides with the edge of the tea tabletop 1 and retracts into its cylindrical groove. Once in position, the locking bead 10 extends out and enters the slot 12 of the tea tabletop 1 to lock. To open, when a certain amount of force is applied, the locking bead 10 retracts into its cylindrical groove, and the tea tabletop 1 can be opened.
