[0022] The utility model is further described in detail below:

[0023] like Figures 1 to 5 As shown, the utility model provides a multifunctional table and chair combination, including an adjustable table board 1 and a seat 2, a lifting bracket 3 and a storage drawer 5 are fixedly installed at the bottom of the adjustable table board 1, and the storage drawer 5 is arranged on the inner side of the lifting bracket 3. The adjustable table board 1 includes a main table board 11, and a mounting groove 12 and a receiving slide groove 13 are opened inside the main table board 11, and the receiving slide groove 13 is arranged on the left and right sides of the mounting groove 12, a rotating rod 14 is rotatably installed inside the mounting groove 12, and a threaded rod 15 is rotatably installed inside the receiving slide groove 13, and a meshing bevel gear 16 is fixedly installed on the inner end of the threaded rod 15 and the outer side of the rotating rod 14, and a hand wheel 17 located outside the main table board 11 is fixedly connected to the front end of the rotating rod 14, and a sliding block 18 is threadedly connected to the outer side of the threaded rod 15, and an extended table board 19 clamped above the receiving slide groove 13 is fixedly installed on the top of the sliding block 18, and a through hole 110 corresponding to the extended table board 19 is opened on the left and right sides of the main table board 11.

[0024] The extended table panel 19 is installed in the receiving slide grooves 13 on both sides of the main table panel 11, and the installation groove 12 is driven to rotate by operating the hand wheel 17 to cooperate with the bevel gear 16 to drive the threaded rods 15 on both sides to rotate, so that the sliding block 18 drives the extended table panel 19 to slide outward, and the extended table panel 19 slides outward along the through opening 110, so as to expand the size of the desktop for use, facilitate adjustment, and improve flexibility. At the same time, by setting a lifting bracket 3, the length of the lifting bracket 3 can be adjusted by operating the lifting bracket 3, and the height of the support of the adjustable table panel 1 can be linearly adjusted by controlling the lifting bracket 3, so as to facilitate flexible adjustment according to children of different heights.

[0025] like Figure 4As shown, the lifting bracket 3 includes a support frame 31, a rotating rod 32 is rotatably installed on the upper part of the support frame 31, threaded rods 33 are rotatably installed on the left and right sides of the support frame 31, meshing bevel gears 34 are fixedly installed on the top of the threaded rod 33 and the left and right sides of the outside of the rotating rod 32, the external thread of the threaded rod 33 is connected to a lifting seat 36, the bottom of the lifting seat 36 is fixedly connected to two supporting legs 37 that penetrate the bottom of the support frame 31, and the bottom of the two supporting legs 37 is fixedly connected to table feet 38.

[0026] By rotating the hand wheel 2 35 located on the side of the support frame 31, the rotating rod 2 32 located on the upper part of the support frame 31 can be driven to rotate, and the rotation of the rotating rod 2 32 can drive the bevel gears 2 34 at both ends to rotate, and the bevel gears 2 34 are used to drive the threaded rod 2 33 on the left and right parts of the support frame 31 to rotate synchronously, and the rotation of the threaded rod 2 33 drives the lifting seat 36 to slide up and down along the inside of the support frame 31, and the lifting seat 36 drives the support legs 37 to slide up and down to provide support for the adjustable table board 1, and the height of the lifting seat 36 in the support frame 31 is adjusted to drive the support frame 31 and the adjustable table board 1 on top of it to be raised and lowered to adjust the height, so as to cooperate with the seat 2 to be adjusted according to the height of different children.

[0027] like Figure 3 As shown, the outer side of the extended table top 19 is movably engaged with the inner side of the through opening 110 .

[0028] The extended table top 19 is movably engaged with the inner side of the through opening 110 so that the extended table top 19 can slide along the through opening 110 to ensure stability.

[0029] like Figure 3 As shown, a dustproof strip 111 located outside the extended table top 19 is fixedly installed on the inner side of the through opening 110 .

[0030] The dustproof strip 111 is arranged in a "U" shape, and the dustproof strip 111 is a dustproof velvet strip.

[0031] The dustproof strip 111 arranged on the inner side of the through opening 110 is a U-shaped dustproof velvet strip. When the extended table board 19 is received into the receiving chute 13 , the dustproof strip 111 blocks the dust on the receiving chute 13 from entering the receiving chute 13 .

[0032] like Figure 2 As shown, the threaded rod 15 is vertically arranged with respect to the receiving slide groove 13 , and the bevel gear 16 is arranged on the inner side of the mounting groove 12 .

[0033] Through the vertically arranged threaded rod 15 and the receiving slide groove 13, the bevel gear 16 located inside the mounting groove 12 is used for transmission, thereby driving the threaded rods 15 on both sides to rotate synchronously, so as to drive the extended table panels 19 on both sides to extend and retract.

[0034] like Figure 4 As shown, the length of the support leg 37 is greater than the length of the support frame 31 , and the support leg 37 is located before and after the threaded rod 2 33 and connected to the bottom of the lifting seat 36 .

[0035] By arranging the support legs 37 at the front and rear parts of the threaded rod 33 and making the length of the support legs 37 greater than the support frame 31, the height of the table top 1 can be adjusted by adjusting the length of the support frame 31 output by the support legs 37, thereby improving the applicability.

[0036] like Figure 4 As shown, a reinforcing cross bar 4 is fixedly connected to the lower inner side of the support leg 37 .

[0037] The lateral support provided by the reinforcing crossbars 4 between the support legs 37 ensures stability.

[0038] The following is a detailed description of the working principle of the multifunctional table and chair combination.

[0039] like Figures 1 to 5 As shown, by rotating the hand wheel 2 35 located on the side of the support frame 31, the rotating rod 2 32 located on the upper part of the support frame 31 can be driven to rotate, and the rotation of the rotating rod 2 32 drives the bevel gears 2 34 at both ends to rotate, and the bevel gears 2 34 drive the threaded rods 2 33 on the left and right parts of the support frame 31 to rotate synchronously, and the rotation of the threaded rods 2 33 drives the lifting seat 36 to slide up and down along the inside of the support frame 31, and the lifting seat 36 drives the support legs 37 to slide up and down to provide support for the adjustable table board 1, and the height of the lifting seat 36 in the support frame 31 is adjusted to drive the support frame 31 and the adjustable table board 1 on top thereof to be raised and lowered to adjust the height, so as to cooperate with the seat 2 to be adjusted according to the height of different children. During use, the hand wheel 17 located in front of the main table panel 11 can be rotated to drive the rotating rod 14 located in the installation groove 12 to rotate. The rotation of the rotating rod 14 drives the bevel gear 16 outside the rotating rod 14 to rotate. The bevel gear 16 provided at the inner end of the threaded rod 15 and meshing with the bevel gear 16 outside the rotating rod 14 drives the threaded rod 15 located on both sides of the rotating rod 14 to rotate. The rotation of the threaded rod 15 drives the sliding block 18 connected to its external thread to rotate and move outward along the receiving slide groove 13. The sliding block 18 drives the extended table panel 19 to move outward so that the extended table panel 19 extends from the side of the receiving slide groove 13 to expand the size of the desktop for use.

[0040] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
