Technical Field
[0001] The present application relates to the technical field of tables and chairs, and in particular to a table and chair that is convenient for lying down. Background Art
[0002] Scientific research shows that good sleep is essential for adolescent brain development, bone growth, physical and mental health, and improving learning efficiency. A nap at noon plays an important role in students' growth and development and afternoon learning. For a long time, the basic structure of desks and chairs used by students in school has not changed much, except for some changes in material, partial appearance, and layout of drawers. Overall, they are still composed of desks and chairs or stools.
[0003] For many years, students have been resting while sitting on chairs or stools, with their arms and heads resting on the desks. Their arms and faces are put under pressure, and their shoulder and neck muscles become stiff due to being in an uncomfortable posture for a long time, which is not conducive to blood circulation. After a nap, their legs, feet, arms and other parts often become numb or even sore.
[0004] Although there are some functional desks and chairs on the market that are suitable for students to lie down and rest, they take up a lot of space and are complicated to operate. In addition, the desks and chairs are separated, which makes the stability low during school breaks. Therefore, there is an urgent need for a desk and chair that meets the requirements of students, which is an urgent problem to be solved. Summary of the invention
[0005] In order to better meet the requirements of students for tables and chairs, the present application provides a table and chair that is convenient for lying down.
[0006] The present application provides a table and chair that is convenient for lying down, which adopts the following technical solution: A table and chair for lying down, comprising a table and a chair, wherein the chair comprises: The bottom frame is placed on the ground for support; A seat plate, arranged on the bottom frame; The adjustment plate is slidably arranged on the bottom frame. In the initial state, the adjustment plate is located below the seat board and is stored inside the bottom frame. When rest is needed, the adjustment plate slides to the outside of the seat board and the upper surface is flush with the upper surface of the seat board and cooperates with the seat board for lying down; the adjustment plate extends under the table and is connected to the table through a connecting component; A backrest, rotatably mounted on the bottom frame and used to support the back and head; The positioning component is used for supporting and positioning the backrest.
[0007] By adopting the above technical solution, when you need to rest, move the adjustment plate to the outside of the seat plate, move the chair to move the adjustment plate under the table and connect it to the table through the connecting component, then unlock the positioning component to adjust the backrest angle, and after the adjustment is completed, the positioning component locks the backrest angle, so you can lie on the backrest, coordinates and adjustment plate to rest, making the rest process more comfortable. At the same time, the adjustment plate extends under the table, so that students can extend their legs under the table when they rest, thereby greatly reducing the space occupied during rest and meeting students' requirements for tables and chairs.
[0008] The adjusting plate and the table are connected to each other through a connecting component, so the table and the bottom frame jointly support the adjusting plate, thereby improving the stability of the adjusting plate. At the same time, the chair and the table are connected together. Because the table is placed with other items such as books, the weight of these items plus the weight of the table itself makes the table more stable, and when multiple tables are leaning against each other, the stability of the table can be further improved. Therefore, by connecting the table and the chair, the stability of students during rest is greatly improved, which can further meet the students' requirements for tables and chairs.
[0009] After the rest is completed, the backrest angle is adjusted to the original angle, the bottom frame is moved to drive the adjustment plate to disengage from the connecting assembly, and then the adjustment plate is moved to the bottom of the seat plate and located on the inner side of the bottom frame. Therefore, the whole process is simple and easy to operate, and the adjustment plate will not affect the use of tables and chairs during study, thereby further meeting the students' requirements for tables and chairs; and because books and other items are placed on the desktop, the structure does not need to use the desktop during rest, reducing the probability of using the desktop and moving items on the desktop, making the tables and chairs very convenient to use, further meeting the students' requirements for tables and chairs.
[0010] Optionally, two connecting components are provided and are located on both sides of the adjustment plate, and the connecting components include: A connecting rod, the bottom of which is rotatably arranged on the table via a rotating shaft and the top of which is inclined upward; A connecting block is arranged on the table, and the connecting rod is positioned against the connecting block under the action of gravity; The supporting plates are arranged on the top of the connecting rod, and the two supporting plates are pressed against the opposite side walls and the lower surface of the adjusting plate for positioning.
[0011] By adopting the above technical solution, after the adjustment plate is moved to the outside of the seat plate, the bottom frame is moved to drive the adjustment plate close to the two support plates, so that the two support plates are pressed against the opposite side walls and the lower surface of the adjustment plate for positioning, thereby supporting the adjustment plate and connecting the table and chairs to each other. When students are resting, the force on the chair is also transmitted to the table for force distribution. At the same time, the connecting block can form a supporting effect on the connecting rod, thereby improving the supporting effect on the adjustment plate, thereby further meeting the students' requirements for tables and chairs.
[0012] At the same time, the top of the connecting rod is tilted upward, that is, the tops of the two connecting rods are close to each other, so that the distance between the tops of the two connecting rods is smaller than the distance between the bottoms of the two connecting rods, thereby reducing the probability of students colliding with the connecting rods when learning to use tables and chairs, improving the comfort of the tables and chairs during use, and meeting the students' requirements for tables and chairs.
[0013] Optionally, the positioning component includes: A slider, which slides up and down and is arranged on the bottom frame; A positioning rod, both ends of which are rotatably connected to the slider and the backrest; The positioning screw is threadedly connected to the sliding block and enables the sliding block to press against the bottom frame for positioning.
[0014] By adopting the above technical scheme, the positioning screw is turned to loosen the slider and the bottom frame, and the backrest is rotated to adjust the angle. The rotation of the backrest drives the positioning rod to rotate and drives the slider to move up and down. After the backrest is adjusted, the positioning screw is turned to position the slider, thereby positioning the backrest, which improves the convenience during adjustment. In addition, the backrest relies on the positioning rod, the slider and the rotation connection point with the bottom frame to divide the force during use, thereby improving the stability of the backrest when in use. After the backrest is subjected to force, the positioning rod generates force on the slider, but the force generates forces in both horizontal and vertical directions. The horizontal force will increase the friction between the slider and the bottom frame, thereby further improving the stability of the backrest when in use, and further being able to meet students' requirements for seats.
[0015] Optionally, the backrest is provided with a support mechanism for supporting the head, and the support mechanism includes: A support block is rotatably arranged on the side wall of the backrest top and abuts against the backrest top or the side wall for positioning; The headrest is slidably arranged on the support block by means of a sliding block. When the support block abuts against the top of the backrest, the headrest is pushed so that the sliding block is inserted and installed on the top of the backrest for positioning; The limiting assembly is arranged on the support block and the backrest and is used for positioning the support block when it abuts against the side wall of the backrest.
[0016] By adopting the above technical solution, students' heads will not come into contact with the backrest when using the desk and chair, so that when resting, it is difficult for the head to be supported by the backrest, which reduces the comfort during use.
[0017] When the desk and chair are normally used, the support block rests against the surface of the backrest that is away from contact with people, and the limit assembly positions it; when a rest is needed, the limit assembly is unlocked, and then the headrest is turned to drive the support block to rest against the top of the backrest, and the headrest is pushed to drive the sliding block to be plugged and installed on the backrest, so that the head can be supported by the headrest when resting, thereby greatly improving the comfort during use, and further being able to meet the students' requirements for seats.
[0018] Optionally, the limiting component includes: The magnet and the iron sheet are respectively arranged on the support block and the side wall of the backrest. When the support block is against the side wall of the backrest, the magnet and the iron sheet are attracted to each other for positioning.
[0019] By adopting the above technical solution, the headrest can be positioned by magnets and iron sheets. The weight of the headrest is relatively small. Therefore, this structure is simple and stable, easy to operate, and can better meet the requirements of students for tables and chairs.
[0020] Optionally, the table comprises: A support frame is placed on the ground; A mobile frame is vertically slidably arranged on the supporting frame; The elastic component is arranged on the mobile frame and is inserted and installed on the supporting frame under the action of elastic force for positioning; A tabletop is disposed on top of the supporting frame; The drawer is arranged on the lower surface of the desktop and is used for placing items.
[0021] By adopting the above technical solution, the position of the desktop can be adjusted through the elastic component, multiple height adjustments can be achieved, and the drawers can facilitate the placement of books and other items, thereby better meeting students' requirements for tables and chairs.
[0022] Optionally, the support frame is provided with a force component for supporting the lower surface of the drawer, and the force component includes: A force distribution block is vertically slidably arranged on the support frame and is threadedly connected with a positioning screw that presses against the support frame for positioning; The force dividing rod has a bottom portion arranged on the force dividing block and a top portion inclined upwardly supported on the lower surface of the drawer to support the force dividing.
[0023] By adopting the above technical solution, the force component rod is used to support and position the lower surface of the drawer, so that the suspended part of the drawer can be supported and positioned, reducing the probability of deformation of the drawer, and turning the positioning screw can also move the force component block and the force component rod, so that the drawer can continue to be supported after the drawer position is adjusted, thereby improving the adaptability of the structure and meeting the students' requirements for tables and chairs.
[0024] Optionally, the support frame is provided with a fixing assembly for fixing the support plate and the adjustment plate to be separated, and the fixing assembly includes: A moving rod is slidably arranged on the supporting frame along the axis of the rotating shaft; A limiting piece is arranged on the moving rod and abuts against the bottom frame and is used to prevent the moving rod from being separated from the bottom frame; a bearing block is arranged on the connecting rod; When the support plate is separated from the adjustment plate, the connecting rod is pushed upward and the bearing block is pressed against the force component rod for positioning, and the moving rod is pressed against the side wall of the connecting rod for positioning and limiting. After the moving rod is pulled to separate from the connecting rod, the connecting rod is pressed against the connecting block under the action of gravity for positioning.
[0025] By adopting the above technical solution, when you need to take a break, pull the moving rod to disengage from the connecting rod, and the connecting rod drives the pallet to move under the action of gravity, so that the connecting rod abuts against the connecting block for positioning, and then the adjustment plate can be placed on the two pallets for support and positioning; after the break is completed, the adjustment plate is disengaged from the two pallets, and the connecting rod is pushed to drive the bearing block to press against the force-dividing rod for positioning, and the moving rod is pushed close to the connecting rod, so that the moving rod abuts against the connecting rod for positioning, thereby making the distance between the two connecting rods larger, reducing the probability of collision with the connecting rod and the pallet when using the tables and chairs, further meeting the students' requirements for tables and chairs; and the bearing block can support and divide the force on the force-dividing rod, thereby further improving the supporting effect on the drawer, further meeting the students' requirements for tables and chairs.
[0026] Optionally, the connecting block is slidably mounted on the supporting frame in a direction close to or away from the connecting rod, a thrust screw for pushing the connecting block to move is threadedly connected to the supporting frame, and a supporting block is arranged on the connecting rod; When the adjustment plate is separated from the support plate, the thrust screw pushes the connecting rod to rotate upward and causes the support block to rest against the force component rod for positioning; or, when the adjustment plate needs to be supported, the thrust screw rotates and causes the connecting rod to rest against the connecting block for positioning under the action of gravity.
[0027] By adopting the above technical solution, after the adjustment plate is separated from the support plate, the thrust screw is turned to push the connecting block to move, and the movement of the connecting block pushes the connecting rod and the support block close to the force-dividing rod, so that the support block is pressed against the force-dividing rod for support and positioning, and the connecting rod and the support plate can also be positioned at the same time; when a rest is needed, the thrust screw is turned to move back, and the connecting rod pushes the connecting block back to its original position under the action of gravity, thereby facilitating the support and positioning of the adjustment plate, improving the convenience during operation, and further meeting the students' requirements for tables and chairs; and the drawer can continue to be supported and positioned after the position of the drawer is adjusted, further improving the comfort of the tables and chairs, and further meeting the students' requirements for tables and chairs.
[0028] Optionally, a placement frame is provided at the bottom of the support frame, which can be used to place objects or feet and prevent the feet from extending to the front row of chairs.
[0029] By adopting the above technical solution, the placement frame can support the students' feet or place objects, and the placement frame can also prevent the feet from extending to the front row of chairs and affecting other students, thereby better meeting the students' requirements for tables and chairs.

The bottom frame 41 is placed on the ground for support, and the seat plate 42 is fixedly mounted on the upper surface of the bottom frame 41. The seat plate 42 is used to support the buttocks.
[0041] Reference Figure 1-Figure 5 Two slideways 6 are provided on the opposite side walls of the bottom frame 41 and below the seat plate 42. The slideway 6 includes a moving section 1 61, a moving section 2 62 and a connecting section 63. The moving section 1 61 and the moving section 2 62 are parallel to each other, and the moving section 2 62 is located above the moving section 1 61 and on the side of the moving section 1 61 close to the table 2. The connecting section 63 is located between the moving section 1 61 and the moving section 2 62 and is connected to one end of the moving section 1 61 and the moving section 2 62 close to each other.
[0042] The adjusting plate 43 is located between the two slides 6 and two adjusting blocks 431 sliding on the slides 6 are fixedly installed on the opposite side walls, so that the adjusting plate 43 slides on the bottom frame 41 and approaches or moves away from the table 2; when the adjusting block 431 is slidably installed on the moving section 1 61 and moves to the end of the moving section 1 61 away from the table 2, the adjusting plate 43 is in a horizontal state and is located below the seat plate 42 and on the inner side of the bottom frame 41; when the adjusting plate 43 moves and drives the adjusting block 431 to move to the connecting section 63, the adjusting plate 43 moves to the outside of the seat plate 42 and is located on the side of the seat plate 42 close to the table 2, and when the adjusting block 431 moves to the end of the moving section 2 62 close to the table 2, the upper surface of the adjusting plate 43 is flush with the upper surface of the seat plate 42.
[0043] When the adjustment plate 43 moves, it first moves horizontally so that the adjustment plate 43 moves to the outside of the seat plate 42, then moves upward obliquely, and then moves horizontally so that the upper surfaces of the adjustment plate 43 and the seat plate 42 are flush, so that the student can lie on the seat plate 42 and the adjustment plate 43 to rest. After resting, the adjustment plate 43 moves back so that the adjustment plate 43 moves to a horizontal state and moves to the bottom of the seat plate 42 and the inside of the bottom frame 41, so as to store the adjustment plate 43.
[0044] After the adjustment plate 43 moves to the outside of the seat plate 42 and the upper surfaces of the two are flush, the end of the adjustment plate 43 away from the seat plate 42 is connected to the table 2 through the connecting component 7, and the moving chair 4 can move the adjustment plate 43 to the bottom of the table 2, that is, between the bottom of the drawer 24 and the support frame 21. There are two connecting components 7 and they are located on both sides of the adjustment plate 43; the connecting component 7 includes a connecting rod 71, a connecting block 72 and a supporting plate 73. The side wall on the opposite side of the support frame 21 and the bottom of the support frame 21 are fixedly installed with a mounting block 12. The bottom of the connecting rod 71 is rotatably installed on the mounting block 12 by a rotating shaft 74, the rotating shaft 74 is in a horizontal state, and the top of the connecting rod 71 is tilted upward. The distance between the tops of the two connecting rods 71 is smaller than the distance between the bottoms, so that the two connecting rods 71 extend close to the adjustment plate 43.
[0045] The connecting block 72 is installed on the side wall of the mounting block 12, and the connecting block 72 is located on the side of the rotating shaft 74 away from the supporting frame 21, and the support plate 73 is fixedly installed on the top of the connecting rod 71. When the two connecting rods 71 are respectively against the top of the two connecting blocks 72 for positioning, the moving adjustment plate 43 is extended to the bottom of the table 2 and between the two support plates 73, so that the two support plates 73 are respectively against the opposite side walls and the lower surface of the adjustment plate 43 for support and positioning; therefore, the connecting component 7 connects the chair 4 and the table 2 to each other, and when students use the table and chairs in normal times, they move between the two connecting components 7, and the distance between the tops of the two connecting rods 71 is small but located above the legs, so that the two connecting components 7 are not easy to interfere with the students' use.
[0046] The chair 4 also includes a backrest 44 and a positioning assembly 5. A vertically upward mounting rod 13 is fixedly installed on the upper surface of the bottom frame 41. Vertically upward guardrails 14 are fixedly installed on the upper surface of the bottom frame 41 and on both sides of the seat 42. The guardrails 14 are used to prevent students from falling from the seat 42, thereby reducing the probability of falling during use, especially during rest; the two mounting rods 13 are located on the side of the guardrail 14 away from the table 2 and on the side of the bottom frame 41 away from the table 2; the bottom of the backrest 44 is rotatably installed on the mounting rod 13, and the top of the backrest 44 is arranged to be inclined upward away from the table 2. The rotation of the backrest 44 makes the top of the backrest 44 approach or move away from the table 2.
[0047] The positioning assembly 5 is used to position the angle of the backrest 44. Two positioning assemblies 5 are provided and are located on two mounting rods 13. The positioning assembly 5 includes a slider 51, a positioning rod 52 and a positioning screw 53. Vertical movable grooves 15 are opened on the opposite side walls of the two mounting rods 13, and vertical sliding holes 16 connected to the movable grooves 15 are opened on the opposite side walls of the two mounting rods 13; the slider 51 is vertically slidably installed on the movable groove 15, and one end of the positioning rod 52 is rotatably installed on the side wall of the backrest 44 and the other end is rotatably installed on the slider 51.
[0048] The positioning screw 53 passes through the sliding hole 16 and is threadedly connected to the slider 51. When the slider 51 moves on the moving groove 15, the positioning screw 53 moves on the sliding hole 16. A knob that is easy to rotate is fixedly installed on the positioning screw 53. The knob presses on the mounting rod 13 and makes the slider 51 press on the moving groove 15, thereby positioning the backrest 44; when the backrest 44 needs to be adjusted, the two knobs are turned to disengage from the mounting rod 13, and the knob is pushed to drive the slider 51 to move. The movement of the slider 51 drives the positioning rod 52 to rotate, and the rotation of the positioning rod 52 drives the backrest 44 to rotate, or the backrest 44 is driven to rotate, or the backrest 44 and the knob are driven at the same time, thereby adjusting the angle of the backrest 44. After the adjustment is completed, the knob is turned to lock it.
[0049] A support mechanism 8 for supporting the head is provided at the top of the backrest 44, and the support mechanism 8 includes a support block 81, a headrest 82 and a limit assembly 83. The support block 81 is rotatably installed on the top side wall of the backrest 44 through a rotating column, and the support block 81 can abut against the top of the backrest 44 or the side wall away from the side in contact with the back after rotation. The support block 81 is slidably installed with a sliding block along a direction parallel to the contact surface between the backrest 44 and the back; when the support block 81 abuts against the top of the backrest 44, the sliding block can be inserted and installed on the top of the backrest 44 for positioning, and the top of the sliding block extends above the support block 81; the headrest 82 is fixedly installed on the top of the support block 81, so as to support the head.
[0050] After resting, pull the headrest 82 to make the sliding block disengage from the top of the backrest 44, and then rotate the headrest 82 to make the support block 81 abut against the side wall of the backrest 44. At this time, the limit assembly 83 is used to position the support block 81 and the headrest 82. The limit assembly 83 includes a magnet 84 and an iron sheet 85. The magnet 84 and the iron sheet 85 are respectively clamped and fixed on the support block 81 and the side wall of the backrest 44. When the support block 81 abuts against the backrest 44, the magnet 84 and the iron sheet 85 are attracted to each other and are used to position the support block 81 and the headrest 82.
[0051] The working principle of the embodiment of the present application is as follows: When it is necessary to rest, the adjustment plate 43 is moved to the outside of the seat plate 42 and flush with the seat plate 42, and the chair 4 is moved so that the adjustment plate 43 is supported on the two supporting plates 73 for positioning, and the knob is turned away from the mounting rod 13 to adjust the angle of the backrest 44. After the adjustment is completed, the knob is turned to press against the mounting rod 13 to position the backrest 44, and the support block 81 is rotated to abut against the backrest 44, and the headrest 82 is pushed to drive the sliding block to be inserted and installed on the backrest 44 for positioning. Therefore, the student can lie on the backrest 44, the seat plate 42 and the adjustment plate 43 with the head supported on the headrest 82 for rest, and the adjustment plate 43 extends to the bottom of the table 2, thereby reducing the space occupied by the table and chair, and also allows the legs and other parts of the student to extend under the table 2 when resting, thereby greatly reducing the space occupied during rest, meeting the student's requirements for tables and chairs, and at the same time, when resting, the chair 4 and the table 2 are connected to each other, so that the stability during rest is higher, thereby further meeting the requirements for tables and chairs.
[0052] After the rest is completed, the backrest 44 is rotated upward so that the backrest 44 can be used for normal study, and then the headrest 82 is pulled to disengage the sliding block from the backrest 44, and the support block 81 is rotated to abut against the backrest 44 and positioned by mutual adsorption of the magnet 84 and the iron sheet 85; the chair 4 is moved to disengage the adjustment plate 43 from the support plate 73, and then the adjustment plate 43 is pushed and placed under the seat plate 42 and on the inner side of the bottom frame 41, so that the chair 4 can be used for study, and the adjustment plate 43 will not cause interference during use, which improves the convenience of using the desk and chair and further meets the students' requirements for the desk and chair. Example
[0053] Reference Figure 5 , Figure 6 and Figure 7The difference between this embodiment and embodiment 1 is that a fixing component 9 is provided on the support frame 21 for fixing the support plate 73 after it is separated from the adjustment plate 43, and two fixing components 9 are provided and are respectively located on two mounting blocks 12; a bearing block 94 is fixedly installed on the side wall of the connecting rod 71 close to the force distribution rod 32. When the adjustment plate 43 is separated from the support plate 73, the connecting rod 71 is rotated to drive the bearing block 94 to press against the force distribution rod 32, and the fixing component 9 is used to position the connecting rod 71.
[0054] The fixing assembly 9 includes a moving rod 91 and a limiting piece 92. The moving rod 91 is slidably arranged on the mounting block 12 along the axis direction of the rotating shaft 74. The moving rod 91 is located on the side of the rotating shaft 74 away from the supporting bottom frame 41. When the bearing block 94 presses against the force-dividing rod 32, the moving rod 91 is positioned against the side wall of the connecting rod 71 away from the supporting bottom frame 41, thereby further reducing the probability of collision between the body parts and the connecting rod 71, the support plate 73 and other structures; the limiting piece 92 is fixedly installed on one end of the moving rod 91, and the limiting piece 92 is positioned against the mounting block 12, and at this time, the limiting piece 92 is located between the connecting rod 71 and the mounting block 12, and the connecting rod 71 can rotate freely.
[0055] The working principle of the embodiment of the present application is as follows: When the adjustment plate 43 is disengaged from the support plate 73 and no support is needed, the connecting rod 71 is rotated upward so that the bearing block 94 is pressed against the force-dividing rod 32, and then the moving rod 91 is pushed close to the connecting rod 71, and the moving rod 91 is positioned against the connecting rod 71, so that the force-dividing rod 32 can be supported and divided. Therefore, the two connecting rods 71 can be moved away from each other without interfering with the students' normal use, and at the same time, the force-dividing rod 32 can be supported and divided, thereby further improving the supporting effect on the drawer 24.
[0056] When the adjustment plate 43 needs to be supported, the moving rod 91 is pulled to drive the limiting plate 92 to abut against the mounting block 12, so that the moving rod 91 is disengaged from the connecting rod 71 and the limiting plate 92 is located between the connecting rod 71 and the mounting block 12, so that the connecting rod 71 can rotate downward under the action of gravity of the support plate 73 until the connecting rod 71 abuts against the connecting block 72 for positioning, thereby further reducing the probability of students colliding with the connecting rod 71 and the support plate 73 during study, and further being able to meet students' requirements for desks and chairs. Example
[0057] Reference Figure 1 , Figure 2 , Figure 8The difference between this embodiment and embodiment 1 is that a guide rail 17 is fixedly installed on the side wall of the mounting block 12, and a connecting block 72 is horizontally slidably installed on the guide rail 17, and the connecting block 72 is close to or away from the connecting rod 71; when the connecting block 72 abuts against the end of the guide rail 17 away from the connecting rod 71, the connecting rod 71 abuts against the connecting block 72 to position the adjustment plate 43; a thrust screw 18 is threadedly connected to the end of the guide rail 17 away from the connecting rod 71.
[0058] The block body 75 is fixedly installed on the side wall of the connecting rod 71 near the force dividing rod 32. When the adjustment plate 43 is disengaged from the support plate 73, the thrust screw 18 is turned to push the connecting block 72 close to the force dividing rod 32. The connecting rod 71 drives the block body 75 to approach and abut against the lower surface of the force dividing rod 32 for positioning, thereby supporting and dividing the force of the force dividing rod 32. Therefore, the two connecting rods 71 can be kept away from each other without interfering with the students' normal use. At the same time, the force dividing rod 32 can be supported and divided, thereby further improving the supporting effect on the drawer 24. Moreover, the change in the position of the thrust screw 18 makes it possible to support the drawer 24 even after the drawer 24 is vertically adjusted. Therefore, the students' requirements for tables and chairs can be further met.
[0059] The working principle of the embodiment of the present application is as follows: When the adjustment plate 43 is disengaged from the support plate 73, the thrust screw 18 is turned to push the connecting block 72 to move so that the block 75 is against the force distribution rod 32 for positioning, thereby supporting the force distribution rod 32, thereby reducing the probability of the connecting rod 71 and the support plate 73 interfering with the students' normal use, and further improving the supporting effect on the drawer 24; at the same time, when support is needed, the thrust screw 18 is turned away from the connecting block 72, and the connecting rod 71 pushes the connecting block 72 to press against one end of the guide rail 17 under the action of gravity, so that the adjustment plate 43 can be placed on the two support plates 73 for support and positioning, so as to further meet the students' requirements for tables and chairs.
[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
