Description

Technical Field

[0001] The utility model belongs to the technical field of folding tables, and more specifically, relates to a folding table and dining table that can be lifted and flipped Background Art

[0002] In transportation, due to space limitations, there are certain requirements for the occupied space of auxiliary tools. Therefore, foldable structures are mostly used in the passenger compartments of passenger transportation vehicles to improve space utilization. Among them, the dining table board, as a commonly used auxiliary device, can be used for meals, office work, etc. The folding of this device can greatly improve the space utilization rate of the carriage

[0003] CN202310177332.6, a lifting and folding table board for automobiles, discloses a support seat, a table board, and a liftable table board base. A transmission screw and a drive motor for driving the transmission screw are provided on the support seat. The table board base is matched with the transmission screw, and the table board is arranged on the table board base through a foldable and unfoldable flipping structure. Although this lifting and folding table board can be lifted and folded up, and the required layout space is small, in the passenger compartment of a rail train, the dining table needs to meet the use of multiple people, the length and volume of the dining table are large, and it is difficult for the motor drive to quickly and stably lift and flip the table board. The existing circuit layout in the passenger compartment of rail transit is difficult to transform, and even unable to meet the motor drive of the table board, which limits the application of the folding table board. In addition, as an auxiliary tool frequently used in the rail passenger compartment, the table board is prone to failure, and once the motor-driven dining table board fails, there are problems such as difficult maintenance and high maintenance costs Summary of the Utility Model

[0004] The utility model provides a folding table and dining table that can be lifted and flipped to overcome the problems of insufficient safety and stability, inconvenient maintenance, and limited application of the existing electrically driven folding table board

[0005] The utility model is realized through the following technical solutions

[0006] A folding table that can be lifted and flipped includes a mounting seat, a guide rail, a slider, a tension device, a rotating shaft, a locking mechanism, and a panel; the guide rail is vertically arranged on the mounting seat, a slider matching with the guide rail is arranged on the guide rail, one end of the panel is connected to the slider through the rotating shaft, the tension device is connected to the panel and provides an upward acting force for the panel, and the locking mechanism is arranged between the mounting seat and the panel. By setting a lifting structure and a flipping structure, when in use, the panel is first vertically lifted from the mounting seat, and the tension device assists in lifting the panel to reduce the force, and then it is horizontally flipped to complete the unfolding of the table board. It can not only be folded to improve space utilization rate, but also be quickly unfolded to provide stable support. The lifting device can also prevent the panel from falling rapidly during recovery, making the recovery process of the dining table stable and safe

[0007] Furthermore, a limit support mechanism for horizontally placing the panel is provided on the mounting base to ensure the horizontal position of the panel during flipping and further improve the support strength after the panel is flipped.

[0008] Furthermore, the tension device includes a tensioner, a cable, and a roller. One end of the cable is connected to the tensioner, and the other end of the cable bypasses the roller and is connected to the panel.

[0009] Furthermore, the roller is installed at the position where the panel rotates horizontally.

[0010] Furthermore, the locking mechanism includes a locking rod provided on the mounting base and a locking hole provided on the side surface of the panel and matching with the locking rod.

[0011] Furthermore, an elastic member is provided between the ejector rod and the mounting base to push the locking rod into the locking hole to complete the locking.

[0012] Furthermore, a sliding groove is provided on the side surface of the panel, and the locking rod moves on the sliding groove as the panel rises or falls, which can further restrict the vertical lifting and falling of the panel.

[0013] Furthermore, a handle is provided on the panel, and the handle is connected to an ejector rod for ejecting the locking rod, and the panel is unlocked through the handle.

[0014] Furthermore, a damping sleeve is also provided on the rotating shaft to provide a damping torque during the flipping of the panel, so that the panel can flip slowly to ensure safety.

[0015] A dining table includes the above-mentioned folding table with lifting and flipping function.

[0016] Compared with the prior art, the beneficial effects are as follows:

[0017] The present utility model provides a folding table with lifting and flipping function, which uses a mounting base with a tension device as the lifting mechanism to complete the rising and falling of the panel in the vertical direction, and then flips through the rotating shaft to fix the horizontal position. The tension device of the present utility model can provide an upward pulling force during the lifting process to assist the user in lifting the panel upward; conversely, the upward pulling force during the panel recovery can prevent the panel from falling rapidly, making the panel recovery process stable and safe. At the same time, installing a damping sleeve on the rotating shaft can ensure the slow and free falling of the panel. The structure of the present utility model is simple, uses a mechanical structure to complete the folding of the table board, is convenient for maintenance, has high safety, and greatly improves the space utilization rate.
