Detailed ways

The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings , so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

As shown in Figure 1 , the foldable integrated student desk and chair of the present invention mainly consists of two parts, a folding table and a folding chair. The folding table part mainly includes a desktop 1, a desktop support frame 2, a lead screw 3, a nut with a bearing seat 4, a linear bearing seat 5, a No. I K-type connecting rod 6, a No. II K-type connecting rod 7, and a base with a slide rail Frame 8, base support frame 9, connecting rod 10, short rod 11, next longest rod 12 and long rod 13. Among them, the desktop 1 and the desktop support frame 2 are hinged by bolts to form a desktop assembly; the bearing seat nut 4 and the linear bearing seat 5 are installed on the No. I K-type connecting rod 6 and the connecting rod 10 respectively, and form a lead screw with the lead screw 3 Nut sub-assemblies; short rod 11, sub-long rod 12 and long rod 13 have 4 pairs in total, each two pairs are connected by bolts on both sides to form a folding adjustment mechanism assembly; base frame 8 with slide rail and base support frame 9 The base assembly is formed by hinged bolts; the tabletop assembly and the base assembly are connected through the folding adjustment mechanism assembly, thereby forming the folding table body.

Wherein, the folding chair part mainly includes a seat surface 14 , No. I folding chair supporting elbow 15 , No. II folding chair supporting elbow 16 , folding chair placement frame 17 and wear-resistant sponge 18 . Wherein, the chair surface 14 is hinged with the No. I folding chair support elbow 15, the No. I folding chair support elbow 15 is hinged with the II folding chair support elbow 16, and the II No. folding chair support elbow 16 is hinged with the No. II folding chair support elbow 15. The folding chair placement frame 17 is hinged; the No. I folding chair support elbow 15 and the No. II folding chair support elbow 16 are all coated with wear-resistant sponge 18 . As shown in the partially cut-away part of Figure 1 , a groove is dug below the chair surface 14, which can be used to place No. II folding chair support elbow 16 when the folding chair is unfolded, so as to fix the position of the folding chair.

As shown in FIG. 2 , the desktop assembly mainly includes a desktop 1 and a desktop support frame 2 . The front end of the desktop 1 is provided with bayonet slots, and the rear end is provided with bolt placement holes. The desktop 1 and the desktop support frame 2 are assembled and fixed together through bayonet slots and hinge connections; several reinforcing ribs 22 are formed under the desktop 1, The two outer sides are provided with outer chute 20, and the two inner sides of desktop support frame 2 are provided with inner chute 21. After the desktop 1 and desktop support frame 2 are fixedly connected, the chute forms a slide rail, and the cylindrical pin 19 can slide in the slide rail. The short rod 11 and the second-long rod 12 are hinged by cylindrical pins 19, and the long rod 13 is hinged with the desktop 1 and the desktop support frame 2, so that the desktop assembly can be connected with the folding adjustment mechanism assembly.

As shown in FIG. 3 , the desktop support frame 2 and the base support frame 9 are removed . The folding adjustment mechanism assembly mainly includes a short rod 11 , a second long rod 12 and a long rod 13 . The aforementioned rods are hinged by bolts, and each pair of short rods 11, pair of medium rods 12 and pair of long rods 13 constitute a group of parallelogram variation mechanisms. Both the desktop 1 and the base frame 8 with slide rails are provided with an outer chute 20, and one end of the short rod 11 and the second long rod 12 is connected together by a cylindrical pin 19 to move in the chute. One end of the two long rods 13 is hinged to the desktop 1 and the base frame 8 with slide rails through bolts. The driving form of the folding adjustment mechanism assembly is manual, driven by the screw nut sub-assembly shown in Figure 1 , which can not only realize the complete folding of the folding adjustment mechanism, but also realize the adjustment to different working heights.

As shown in Figure 4 , the base part includes a base frame 8 with slide rails and a base support frame 9. Offer the outside chute 20, offer the inside chute 21 on the base support frame 9, the slide rail that aforementioned chute forms is connected with the cylindrical pin 19 of folding lifting part. The inner side of the base frame 8 with slide rails has a groove, and the folding chair placement frame 17 and the inner groove of the base frame 8 with slide rails transitionally cooperate to form a mobile pair, which is used to store and hide the fully folded folding chair shown in the figure .

When in use, first place the fully folded table and chair on the flat ground, pull out the folding chair placement frame 17 to a suitable position, and lift the chair surface 14 upwards until the No. Fix the folding chair position. Then lift the desktop part to a certain height, and turn the lead screw 3 at the same time, the nut 4 with bearing seat moves relative to the lead screw 3, and the lead screw rotates in the linear bearing seat 5 without moving, so the nut 4 with bearing seat and the linear bearing seat 5 moves relatively, thereby driving the parallelogram bar system hinged to it to deform freely. Adjust the table to a suitable height. Due to the self-locking effect of the nut and screw pair, the height of the table and chair can be locked at any position. When folding, the chair is completely folded and stored in the belly of the table, and then the screw 3 is turned in the opposite direction to completely fold the table. As shown in Figure 6 , it is a view from all directions of the foldable integrated student desk and chair completely folded and stored.
