The gear adjustingopening positioning groove 3 may be integrally formed at the bottom of thetable board 1, or may be first disposed on a fixing member, and then the fixing member is fixedly connected to the bottom of thetable board 1, where the fixing member may be a plate-shaped fixing member or a strip-shaped fixing member integrally formed with a plurality of gear adjustingopening positioning grooves 3, in this embodiment, 2 identical strip-shaped fixing members 6 are taken as an example, but not limited to the structure shown in the figure, or may be more than 3 strip-shaped fixing members, or may be one or more plate-shaped fixing members, where the 2 strip-shaped fixing members 6 in this embodiment are not particularly limited, and are axisymmetrically fixed at the bottom of thetable board 1, and 3 gear adjustingopening positioning grooves 3 are shown on the strip-shaped fixing member 6 in the figure, but not limited to the number of gears, and the number of gears can be adjusted according to the design requirement, that is, and the number of gears adjustingopening positioning grooves 3 can be designed according to the number of the required gears. Moreover, the gear adjustingopening positioning groove 3 is preferably an opening kidney-shaped groove so as to facilitate adjusting operation, the opening 3-1 of the opening kidney-shaped groove faces downwards, and the inner diameter of the opening 3-1 is matched with the outer diameter of thetransverse rod 5 so as to ensure that thetransverse rod 5 can be smoothly clamped into the gear adjusting openingpositioning groove 3 through the opening 3-1.

In this embodiment, the two ends of thetransverse rod 5 are respectively sleeved with thepositioning stop blocks 7, and thepositioning stop blocks 7 can be attached to and blocked on the outer side surface of the gear adjustingopening positioning groove 3, so as to avoid the influence on the stability of the folding table caused by the displacement of thetransverse rod 5 in the gear adjustingopening positioning groove 3.

In this embodiment, the two support arms 4-1 of the U-shapedconnector 4 are fixedly provided with the U-shapedconnector limiting baffle 8, the free end of the U-shapedconnector limiting baffle 8 can overlap with the support rod 2-11b of the leg frame with shorter length formed on the corresponding side, and as a preferred scheme, the support rod 2-11b on at least one side is provided with therotatable lock catch 9 for locking the U-shapedconnector limiting baffle 8, and therotatable lock catch 9 is pressed on the U-shapedconnector limiting baffle 8 to play a role in locking the U-shapedconnector limiting baffle 8, so that the two support arms 4-1 of theU-shaped connector 4 and the support rod 2-11b of the leg frame with shorter length are located on the same plane, so that the folding table has better stability.

Because thetransverse rod 5 is required to be separated from the gear adjustingopening positioning groove 3 when the folding table is folded, in order to enable thetransverse rod 5 to be well positioned when the folding table is folded, the bottom of thetable plate 1 is fixedly provided with thelimiting bars 10 for limiting the storage of thetransverse rod 5, and the problem of displacement of thetransverse rod 5 after the folding can be solved by enabling thetransverse rod 5 to be positioned in thelimiting bars 10, so that the stability of the folding table when the folding table is folded can be well ensured, and the folding table is very beneficial to packaging, carrying and storing.

The specific operation of the folding table for realizing the height adjustment is as follows:

firstly, therotatable lock catch 9 is unlocked to limit thebaffle 8 of the U-shaped connecting piece, then thetransverse rod 5 is clamped in the most far end gear adjustingopening positioning groove 3a far away from the support leg frame 2-1a with longer length, and then therotatable lock catch 9 is locked to limit thebaffle 8 of the U-shaped connecting piece, as shown in figure 4, the opening angle between the two groups of support leg frames 2-1 forming thecrossed support leg 2 is in the maximum state, so that the height of the folding table is at the lowest height;

in the same way, if thetransverse rod 5 is clamped in thepositioning groove 3b of the nearest gear adjusting opening near the leg frame 2-1a with longer length, as shown in fig. 5, the opening angle between the two groups of leg frames 2-1 forming thecrossed legs 2 is in the minimum state, so the height of the folding table is at the highest height;

in addition, by adopting the operation and adjustment principle, theopening positioning groove 3 can be adjusted in the required gear by adjusting thetransverse rod 5 so as to change the opening angle between the two groups of support leg frames 2-1, thereby realizing the adjustment requirements of different heights of the folding table.

The folding table disclosed by the utility model is particularly operated as follows:

when the folding table needs to be folded, therotatable lock catch 9 is firstly enabled to unlock the limitingbaffle 8 of the U-shaped connecting piece, then thetransverse rod 5 is enabled to be separated from the gear adjustingopening positioning groove 3, thetransverse rod 5 is enabled to be positioned in thelimiting column 10 at the forefront end of the strip-shaped fixing piece 6, then theU-shaped connecting piece 4 is enabled to reversely overturn to be in parallel contact with the bottom of thetable board 1, and finally the two groups of leg frames 2-1 forming thecrossed legs 2 are enabled to be folded towards the far end direction of the strip-shaped fixing piece 6 to be in parallel contact with the bottom of thetable board 1, and the folding table is only needed, as shown in fig. 6 and 7.

As can be seen from the above: the folding table convenient to package and capable of adjusting the height provided by the utility model not only realizes folding and height-adjustable functions through ingenious structural design, but also has the advantages of simple structure, simplicity and convenience in operation, good stability and the like, and particularly, the two groups of support leg frames can be folded in parallel in the same direction, and the folding table has the advantages of small package volume, easiness in package and boxing and the like, so that the boxing amount and the transportation convenience are obviously improved, the packaging and transportation cost is obviously reduced, and the damage of the support leg frames in transportation is avoided; therefore, compared with the prior art, the utility model has the advantages of remarkable practical value and wide application range.
