[0002] In order to adjust the sitting posture of children to prevent hunchback and myopia, existing study tables and chairs are usually provided with a lifting mechanism, and the sitting posture of children is adjusted by lifting and lowering the lifting mechanism;

[0003] The most commonly used and lowest-cost lifting structure is usually a sleeve type. The height is adjusted by passing a screw through two sleeves and fixing the connection position between the sleeves. At the same time, in order to adjust the height between the sleeves, a sufficient gap is usually left between the two sleeves. Although this is convenient for adjusting the height, during normal use of tables and chairs, the sleeves may move left and right, causing the tables and chairs to twist, affecting the stability of the tables and chairs.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example

[0029] See also Figure 1 and Figure 2The utility model provides a technical solution: a ball slide frame, including a shell 1, a mounting groove 15 for mounting a rolling element 2 is opened in the shell 1, symmetrically distributed grooves 16 are arranged on both sides of the shell 1, the grooves 16 are connected to the mounting grooves 15, and a partition 3 is arranged on the bottom of the two grooves 16, and the partition 3 divides the mounting groove 15 into two upper and lower areas, and also includes a plurality of rolling elements 2 arranged in the mounting groove 15, the rolling elements 2 are distributed in a ring shape around the partition 3, and the partition 3 guides the rolling of the rolling elements 2, and the rolling elements 2 are spheres or cylinders, which reduces the two support tubes 6 and The friction between the sleeves 5 makes the two slide more smoothly. The top surface of the rolling element 2 is higher than the upper end surface of the shell 1. Multiple ball slide racks are fixed on each inner wall of the sleeve 5. The rolling element 2 is pressed against the inner wall of the sleeve 5 to fill the gap between the sleeve 5 and the support tube 6, avoiding the sleeve 5 and the support tube 6 from moving during sliding, thereby improving its stability during the lifting process. At the same time, the connection strength between the sleeve 5 and the support tube 6 is enhanced, avoiding the sleeve 5 from moving on the outside of the support tube 6, improving the stability of the tables and chairs when in use, and preventing movement.

[0030] like Figure 2 and 3 As shown, a pad 4 is also fastened on the partition 3. The two ends of the pad 4 are in the shape of barbs, which are fastened to the two ends of the bottom of the partition 3. The pad 4 increases the height of the rolling element 2 on the partition 3, and the specifications of the pad 4 can be selected in different thicknesses according to needs. Pads 4 of different thicknesses can increase the height of the rolling element 2, so that the top surface of the rolling element 2 just rests on the inner wall of the sleeve 5, thereby improving the application range of the ball slide frame, and can support sleeves 5 of different specifications.

[0031] like Figure 3 As shown, the partition 3 is U-shaped, and both end surfaces of the partition 3 are connected with flanges 31, and the flanges 31 are located on the outer sides of the upper ends of the two side surfaces of the partition 3. The outer surfaces of the two side surfaces of the upper end of the shell 1 are connected with folded edges 14. The flanges 31 and the folded edges 14 are at the same height and have the same width, and are both used to press on the support tube 6 to position the installation height of the shell 1 to prevent the shell 1 from sinking into the support tube 6 as a whole.

[0032] The shell 1 includes a symmetrical left shell 11 and a right shell 12. The left shell 11 includes a side plate 111 and a connecting plate 112 formed on the edge of the side plate 111. An opening is opened at the upper end of the connecting plate 112 to allow the rolling element 2 to protrude from the shell 1 and abut against the sleeve 5. The mounting groove 15 is formed by the connecting plate 112 around the side plate 111. The two ends of the mounting groove 15 are arc-shaped, and the two ends of the arc can guide the rolling element 2. The mounting groove 15 is used to install the rolling element 2. The rolling element 2 is annular and distributed in sequence along the elliptical mounting groove 15. A connecting portion 113 that is mutually plugged with the right shell 12 is formed on the connecting plate 112. The connecting portion 113 is a plug-in column or a plug-in hole, which enhances the connection strength between the left shell 11 and the right shell 12.

[0033] like Figure 4 As shown, spring pieces 13 are formed on both side surfaces of the left shell 11 and the right shell 12 and extend outward. The spring pieces 13 are formed on the outside of the connecting plate 112. The spring pieces 13 are used to clamp the shell 1 in the support tube 6. The spring pieces 13 are squeezed and deformed when the shell 1 is installed, which facilitates the insertion of the spring pieces 13 in the support tube 6. After insertion, the spring pieces 13 will reset and open. The volume of the spring pieces 13 is larger than the volume of the socket, so the shell 1 is clamped in the support tube 6 to prevent the shell 1 from slipping.

[0034] The top surface of the spring sheet 13 is lower than the upper end surface of the shell 1. The distance between the spring sheet 13 and the top surface of the shell 1 is equal to the wall thickness of the support tube 6. The support tube 6 is clamped between the spring sheet 13 and the upper end surface of the shell 1 through the spring sheet 13 to completely fix the shell 1 and prevent the ball slide frame from being offset as a whole.

[0035] like Figure 5 As shown, the utility model also provides a technical solution: the slide system of the ball slide frame includes a support tube 6, a sleeve 5 and the above-mentioned ball slide frame, the sleeve 5 is sleeved on the outside of the support tube 6, the ball slide frame is installed on the surface of the support tube 6, and the top surface of the ball slide frame is against the inner wall of the sleeve 5. The ball slide frame enhances the supporting force between the support tube 6 and the sleeve 5, prevents the sleeve 5 and the support tube 6 from moving and twisting, and improves the stability during the lifting process and the use process.

[0036] like Figure 6 and 7 As shown, a mounting hole 61 for embedding the ball slide frame is opened on the support tube 6, and the mounting hole 61 includes a rectangular hole, and spring clip insertion holes 62 are opened on both sides of the rectangular hole. The spring clip insertion holes 62 are opened on the sides of the rectangular hole. The spring clip insertion holes 62 are convenient for squeezing the spring clip 13 and inserting the shell 1 into the support tube 6 to complete the installation of the shell 1.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
