DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1

[0031] The present invention provides a multifunctional desk and chair for sitting or lying, comprising a desk body 1 and a chair body 4. A translation device 2 for adjusting the horizontal position of the desk body 1 is arranged at the bottom of the desk body 1, and a rotating mechanism 3 for adjusting the backrest angle is arranged on the outer side of the chair body 4. A soft plastic protective cover 21 in the translation device 2 is slidably connected to both sides of the bottom of the desk body 1.

[0032] A base rod 21 and an outer rod 22 are sequentially arranged inside the soft plastic protective cover 21 , and a pull rod 23 is slidably connected to the outer sides of the base rod 21 and the outer rod 22 .

[0033] The soft plastic protective cover 21 can play a protective role, and the cooperation of the base rod 21 and the outer rod 22 can realize the forward and backward pushing and sliding operations.

[0034] It is used to adjust the position of the desk body 1 horizontally so as to adapt to the space inside the classroom, so that the front and rear desks will not touch each other, thus maximizing the use of space, and it can also be adjusted according to the use and needs of students;

[0035] Among them, the first adjustable bracket 9 is bolted on both sides of the bottom of the desk body 1, and the leg rest 10 is rotatably connected to the center of the inner side of the first adjustable bracket 9. The leg rest 10 is used to support the legs, and learning materials can also be placed inside it. In addition, the leg rest 10 and the first adjustable bracket 9 are rotatably connected through a damping shaft to prevent them from rotating freely and randomly. They cannot rotate freely without applying external force. At the same time, the first adjustable bracket 9 can adjust the upper and lower heights, and the arbitrary adjustment operation can be achieved by installing and removing bolts.

[0036] The state shown in the figure is the state after adjustment;

[0037] In addition, magnetic positioning beads are provided, which facilitate magnetic positioning when no forward and backward adjustment is required, thereby realizing auxiliary positioning operation;

[0038] The interior of the desk body 1 can be convenient for placing study materials and books, while the leg rest 10 can also place books and study materials.

[0039] Based on the above, it is mainly used in schools, which is convenient for students to study, and can be quickly unfolded and positioned, so that students can lie down and rest during lunch break, ensuring the quality of students' naps during lunch break. It can not only ensure the physical and mental health of students, but also effectively improve learning efficiency through good rest.

[0040] Preferably, the rotating mechanism 3 includes a supporting component, a displacement component and a connecting component. The supporting component is arranged on the outside of the chair body 4, the displacement component is arranged inside the supporting component, and the connecting component is arranged on the outside of the displacement component.

[0041] like Figure 5 As shown, the connection seat 31 in the support assembly is fixedly installed on the outside of the chair body 4, and a second spring 32 is welded inside the connection seat 31. The connection seat 31 is used to connect the internal and external components, and the second spring 32 plays the role of elastic connection.

[0042] like Figure 5 As shown, the tooth plate 33 in the displacement assembly is welded to the outer end of the second spring 32, and a connecting block 34 is fixedly installed on one side of the tooth plate 33. The connecting block 34 and the connecting seat 31 are through-type slidingly connected. The tooth plate 33 can achieve the function of auxiliary clamping, and the connecting block 34 can achieve the stability of lateral movement to avoid rotation caused by large rotational force.

[0043] like Figure 5 As shown, the groove plate 35 in the connecting assembly rotates inside the connecting seat 31, the tooth plate 33 is clamped with the groove plate 35, the outer end of the connecting seat 31 is rotatably connected with the bearing seat 36, and a pressing rod 37 is fixedly installed in the middle of the clamping surface of the tooth plate 33, and the bearing seat 36 and the tooth plate 33 are fixedly installed. The groove plate 35 is mainly used to adapt to the tooth plate 33, so as to facilitate the locking operation when it is not rotating. The bearing seat 36 is used to support and connect the back plate 7, and the setting of the pressing rod 37 is convenient for controlling whether the tooth plate 33 and the groove plate 35 are clamped and engaged.

[0044] As shown in the figure, the back plate 7 is in a vertical state. When it needs to be adjusted:

[0045] It is necessary to press the pressing rod 37 first, and then the pressing rod 37 pushes the tooth plate 33 to move. At this time, the tooth plate 33 will be out of the clamping state between the groove plate 35, and at the same time, the second spring 32 will be squeezed, causing the second spring 32 to be compressed. In addition, the tooth plate 33 will also drive the connecting block 34 to move until the connecting block 34 is located inside the adapter hole and slides;

[0046] Since the back plate 7 is fixedly mounted on the bearing seat 36, and the other side of the back plate 7 is rotatably connected to the chair body 4, the connectivity of the back plate 7 is ensured;

[0047] At this time, the rotation adjustment can be carried out by directly rotating the back plate 7. At this time, the back plate 7 will drive the parts connected to it and its bottom will also drive the bearing seat 36 to rotate. When the bearing seat 36 rotates, it will drive the groove plate 35 to rotate until it stops rotating after rotating to the required position. At this time, the pushing force applied to the pressing rod 37 is released, and the elastic push of the second spring 32 causes the tooth plate 33 and the groove plate 35 to be engaged to complete the adjustment of the angle after rotation.

[0048] Among them, the bearing seat 36 is sleeved on the outside of the pressing rod 37, and an adaptation hole is opened on the outside of the chair body 4. The connecting block 34 is located inside the adaptation hole. The opening of the adaptation hole facilitates the adaptation of the connecting block 34, so that the connecting block 34 can move stably horizontally.

[0049] The bottom of the chair body 4 is bolted with a second adjustable bracket 8 , and the top of the bearing seat 36 is fixedly mounted with a backboard 7 . The second adjustable bracket 8 is used to adjust the height position of the chair body 4 .

[0050] In addition, a mounting plate 5 is bolted to the back of the back panel 7, and a headrest 6 is bolted to the back of the mounting plate 5. The mounting plate 5 and the back panel 7 are bolted together, so when they are connected, the height position can be adjusted as needed, and the headrest 6 can be wrapped with cotton or memory foam so that the head and neck can be supported when lying flat, thereby improving the rest comfort.

[0051] In addition, the interior of the leg rest 10 is hollow, and the interior of the desk body 1 is hollow. Both are hollow and can hold corresponding or appropriate learning materials and textbooks as needed.

[0052] Based on the above, the first adjustable bracket 9 and the second adjustable bracket 8 can be divided into a bottom bracket and a moving rod, and both are composed of a bottom bracket and a moving rod. Since the bottom bracket is sleeved on the outside of the moving rod, when height adjustment is required, the bolts connecting the bottom bracket and the moving rod need to be released, and then the desk body 1 can be directly pulled upward to achieve the advantages and effects of height adjustment. After adjustment, the bolts are passed through the bottom bracket and the moving rod to complete the support of the moving rod and the top desk body 1, and the bottom bracket and the moving rod can be locked by the bolts;

[0053] Based on the above;

[0054] The method of adjusting the height position of the desk body 1 is not limited to the above-mentioned method;
