Description

Technical Field

[0001] The utility model relates to a portable table with a flippable table top, in particular to a pneumatic flippable table top and a portable table. Background Art

[0002] Current portable tables usually include a base, a telescopic bracket, a fixed shaft, and a table top. The lower end of the telescopic bracket is fixed to the base, and the upper end is fixedly connected to the fixed shaft. The lower surface of the table top is fixedly mounted on the fixed shaft via a lockable latch. The latch passes through the fixed shaft, and the outer side is fixed to the table top by bolts. When in use, the table top is flipped around the fixed shaft as the rotating axis. At this time, the latch fixedly connected to the table top rotates around the fixed shaft, and then the latch is tightened to fix the table top. However, when the items placed on the table top are heavy, the friction between the latch and the fixed shaft is too small, which will cause the table top to continue to tilt, and the locking effect is usually not achieved. At the same time, when the table top is placed flat, if the weight on the left and right sides of the fixed shaft is unbalanced, the friction between the latch and the fixed shaft is too small, which will also cause the table top to tilt, and then the items on the table top will slide off. Therefore, how to effectively improve the effect and efficiency of the table top flipping is a problem that needs to be considered. Utility Model Content

[0018] like Figure 1As shown, the pneumatic flip table top includes a table top body 1, a fixing frame 2, a gas spring 9 and a hinge. The fixing frame 2 is connected to the table top body 1 through a hinge. The fixing frame 2 is provided with an extension end 6 downward, and the extension end 6 is connected to the piston rod of the gas spring 9 through a rotating shaft 11. The other end of the piston rod is connected to the cylinder of the gas spring 9. The other end of the cylinder of the gas spring 9 is provided with a control handle 10. The control handle 10 is fixedly connected to the table top body 1. The hinge and the gas spring 9 are located on the left and right sides of the fixing frame 2. When the gas spring 9 and the table top body 1 rotate through the rotating shaft 11, the table top body 1 rotates relative to the fixing frame 2 through the hinge.

[0019] Combine Figure 2 As shown, the table top body 1 is rectangular. In other embodiments, a circular or other shape may also be used. A cup holder or other components may be provided on the upper surface, which serves as a movable plate of the table top. The table top also includes a fixed plate (not shown in the figure) arranged in parallel with the table top body 1. The lower surface of the fixed plate is fixedly connected to the fixing frame 2 by bolts to keep it stationary. When there is one fixed plate, it is located on the front or rear side of the table top body 1. When two fixed plates are provided, they are located on the front and rear sides of the table top body 1, so that the table top body 1 is located between the two fixed plates.

[0020] The fixing frame 2 is fixedly connected to the table board body 1 by bolts and is installed on the lower surface of the table board body 1. The fixing frame 2 can be connected to the base through the telescopic bracket 3. The fixing frame 2 is provided with at least one support frame, one of which is fixedly connected to the table board body 1 through a gas spring and a hinge. In this embodiment, one end of the fixing frame 2 is connected to the telescopic bracket 3, and the other end is provided with two parallel support frames, namely a first support frame 4 and a second support frame 5. The left and right sides of the first support frame 4 are fixedly connected to the gas spring 9 and the lower surface of the table board body 1 through hinges, respectively. Furthermore, the end of the first support frame 4 is provided with an extension end 6 downwardly, and the lower part of the extension end 6 is connected to the piston rod of the gas spring 9 through a rotating shaft 11.

The hinges are provided in two groups, namely the first hinge 7 and the second hinge 8. One end of the hinge is fixedly connected to the first support frame 4 by bolts, and the other end is fixedly connected to the lower surface of the table board body 1 by bolts. The extension end 6 is also a rectangular structure, the upper end is connected to the first support frame 4, and the lower end is provided with a through hole. The piston rod of the gas spring 9 is also provided with a through hole, and the two through holes pass through the rotating shaft 11. The two ends of the rotating shaft 11 are fixed by bolts to prevent the rotating shaft 11 from detaching from the gas spring 9 and the extension end 6. The gas spring 9 can rotate through the rotating shaft 11.

[0022] The first support frame 4 and the second support frame 5 are both provided with bolt holes for fixing to the hinges, and both ends are provided with extension ends 6. The table top body 1 is also provided with bolt holes for fixing to the hinges on both sides of the two support frames. In this way, any support frame can be selected for installation.

A valve is provided at the other end of the cylinder, and the valve is controlled by a control handle 10. Pulling the control handle 10 opens the valve, thereby adjusting the length of the piston rod extending into the cylinder. The control handle 10 is fixed to the lower surface of the table board body 1 by a bolt 12. The control handle 10 can extend to the outside of the table board body 1, and the direction of pulling the valve is upward, so that when the user adjusts the flip angle of the table board body 1, the user can press the palm of the hand on the upper surface of the table board body 1 and pull the control handle 10 upward with the fingers to flip the table board body 1. When the table board body 1 is flipped into place, the user releases the finger pulling the control handle 10, and the adjustment is completed.

The upper end of the upper bracket 14 is fixedly connected to the fixing frame 2 via bolts, and the lower end extends into the lower bracket 15. The side of the lower bracket 15 is provided with an opening, and a fastening bolt 13 is provided in the opening. By tightening the fastening bolt 13, the position where the upper bracket 14 extends into the lower bracket 15 can be limited, thereby achieving the length adjustment of the telescopic bracket 3.

[0025] The bottom of the lower bracket 15 is fixedly connected to the base 16 by bolts. Furthermore, the telescopic bracket 3 can adopt a gas spring structure, and the control handle of the telescopic bracket 3 can be installed on the lower surface of the table body 1 near one side of the telescopic bracket 3.

[0026] Furthermore, based on the present invention, the pneumatic flip table top and portable table can also be replaced by an electric push rod. For example, the gas spring 9 adopts an electric push rod, and the telescopic bracket 3 adopts an electric push rod.

[0027] The pneumatically flippable tabletop and portable table, through the design of the gas spring structure, can easily flip the tabletop and effectively prevent the tabletop from rotating after flipping. Combined with the hinge design, the maximum angle to which the tabletop can flip can be controlled. Furthermore, the design of the fixing frame ensures that the tabletop is more stable when laid flat. The utility model has a simple structure, flexible operation, convenient use, and is convenient and durable.
