[0026] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:
[0027] See also Figure 1-8The utility model provides an embodiment: an adjustable plastic table, including a table 10, a left bracket 13 and a right bracket 14, a connecting assembly 20 is arranged at the intersection of the support rods of the left bracket 13 and the right bracket 14, the bottom of the support rods of the left bracket 13 and the right bracket 14 are fixedly connected with a bottom rod 17, the surface of the bottom rod 17 is provided with a rubber sleeve, the bottom of the table 10 is provided with an intermediate cavity 11, the left bracket 13 and the cross bar at the top of the right bracket 14 are rotatably provided with a set 15, the set The upper half of the component 15 is slidably connected in the middle cavity 11, so that the left bracket 13 and the right bracket 14 can be rotated. At the same time, the component 15 slides in the middle cavity 11, so that the height of the desktop can be adjusted. As for the connecting component 20, it includes a connecting sleeve 22 fixedly installed on the support rod of the right bracket 14, and a hollow column 21 is fixed through the support rod of the left bracket 13. The hollow column 21 extends through the inner cavity of the connecting sleeve 22 and is rotatably connected to the connecting sleeve 22. A sliding column 24 is horizontally and transversely slidably connected in the hollow column 21. The sliding column 24 is fixedly connected to a toothed plate 26 at the end face of one side close to the connecting sleeve 22. The toothed plate 26 is evenly distributed with no less than four rectangular teeth 27. A corresponding number of slots 28 are evenly distributed on the outer end face of the connecting sleeve 22. The rectangular teeth 27 are embedded in the slots 28. When the height of the tabletop needs to be adjusted, the sliding columns 24 on both sides are first pushed inward to move the toothed plate 26 toward the center of the table. At the same time, the rectangular latch tooth 27 is disengaged from the latch groove 28, and the slide column 24 is rotated to make the rectangular latch tooth 27 abut against the outer edge end of the connecting sleeve 22. At this time, the left bracket 13 and the right bracket 14 are rotated to adjust the angle, and then the height of the desktop can be adjusted to a certain extent. After adjustment, the slide column 24 is rotated again and pulled back at the same time, so that the rectangular latch tooth 27 is embedded in the latch groove 28 to form a limit fixation, which can effectively ensure the stability and strength of the table and is very convenient to use.

The connecting sleeve 23 and the connecting sleeve 22 are in contact with each other, so that the left bracket 13 and the right bracket 14 support rods are isolated to a certain extent, but the strength of the support connection will not be affected.
[0030] In addition, in one embodiment, for some tables 10 that do not need to be completely disassembled and stored, in this embodiment, embedded grooves 12 are respectively provided on the front and rear side walls of the above-mentioned intermediate cavity 11, and protrusions 16 are respectively provided on both sides of the upper half of each of the kits 15. The protrusions 16 are respectively slidably embedded in the corresponding embedded grooves 12, which can not only ensure sliding during adjustment, but also limit the position between the table 10 and the kit 15.
[0031] During specific implementation, when it is necessary to adjust the height of the table top, first press the pressure cover 25 and push the slide column 24 inward, so that the tooth plate 26 moves toward the center of the table, and at the same time, the rectangular tooth 27 is disengaged from the slot 28, and then the pressure cover 25 is rotated so that the rectangular tooth 27 abuts against the outer edge end of the connecting sleeve 22. At this time, the left bracket 13 and the right bracket 14 are rotated to adjust the angle, and then the height of the table top can be adjusted to a certain extent. After adjustment, the slide column 24 is rotated and pulled back at the same time, so that the rectangular tooth 27 is embedded in the slot 28 to form a limit fixation, which can effectively ensure the stability and strength of the table and is very convenient to use.
