Technical Field

[0001] This utility model relates to the field of furniture, and more specifically, to a modular table and chair set. Background Technology

[0002] Existing tables include supporting legs and a tabletop, while chairs include a backrest, a seat, and supporting legs. Most existing tables and chairs adopt a separate design for the table and chair. Although some tables and chairs adopt an integrated design for the tabletop and chair, the tabletop cannot be adjusted in distance or height on the chair, making the use of the tabletop on the chair relatively limited.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a modular table and chair.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a combined table and chair, including a seat, a rotating rod rotatably connected to the bottom surface of the seat and extending from the side of the seat, a telescopic rod slidably connected to the length of the rotating rod, a tabletop provided at the end of the telescopic rod detached from the rotating rod, a second telescopic rod rotatably connected to the tabletop, a limit ring fixedly connected to the end face of the second telescopic rod, a limit hook fixedly connected to the outer wall of the first telescopic rod for hooking the limit ring, a receiving groove for accommodating the rotating rod being opened on the bottom surface of the seat, the depth of the receiving groove being greater than the thickness of the rotating rod, and when the rotating rod rotates toward the bottom surface of the seat, both the first telescopic rod and the tabletop are located below the seat.

[0006] The present invention is further configured such that: the telescopic rod two includes a sleeve two and a connecting rod two; the sleeve two is rotatably connected to the end face of the table; the limiting ring is fixedly connected to the end face of the connecting rod two near the telescopic rod one; the outer wall of the sleeve two is provided with a threaded groove, and one end of the adjusting bolt passes through the threaded groove and abuts against the outer peripheral wall of the connecting rod two.

[0007] The present invention is further configured such that: the end of the telescopic rod near the rotating rod is provided with an opening for the rotating rod to pass through, and a positioning member is provided between the telescopic rod and the rotating rod for fixing the two together.

[0008] The present invention is further configured such that: the positioning element is a bolt, and the telescopic rod has a threaded hole for the bolt to pass through, and one end of the bolt passes through the threaded hole and abuts against the outer peripheral wall of the rotating rod.

[0009] The present invention is further configured such that: the telescopic rod includes a sleeve and a connecting rod arranged coaxially; the limiting hook is fixedly connected to the outer wall of the sleeve; one end of the connecting rod is fixedly connected to the table; the opening is opened on the sleeve; and the end of the sleeve away from the rotating rod is provided with a positioning element for fixing the connecting rod.

[0010] The present invention is further configured such that: the second positioning element is a second bolt, and the end of the first sleeve away from the rotating rod is provided with a second threaded hole for the second bolt to pass through, and one end of the second bolt passes through the second threaded hole and abuts against the outer peripheral wall of the first connecting rod.

[0011] The present invention is further provided with a fixing component for fixing the rotating rod on the bottom surface of the chair seat.

[0012] The present invention is further configured such that: the fixing component includes a first pin seat and a second pin seat fixedly connected to one side of the receiving groove, and a first plug and a second plug fixedly connected to the other side of the receiving groove. A first plug seat is slidably connected to a first plug rod for embedding into the first plug, and a second plug seat is slidably connected to a second plug rod for embedding into the second plug.

[0013] In summary, this utility model has the following beneficial effects: When the user rotates the rotating rod to the side of the chair seat, it drives the telescopic rod and the table. When both the telescopic rod and the table are rotated to the side of the chair seat, the axial direction of the table and the axial direction of the chair seat are relatively parallel, and the rotating rod, the telescopic rod, and the table are all in the extended state. At this time, the telescopic rod can be slidably adjusted on the rotating rod according to the user's usage habits, thereby changing the horizontal distance between the table and the chair seat. Similarly, the user can also adjust the relative height of the table to the chair seat by extending and retracting the telescopic rod, thus allowing the user to adjust the height of the table from the chair seat according to their usage habits. The height of the tabletop can be adjusted to be level or adjusted to the height of the chair seat. The rotating rod rotates from the side of the chair seat to prevent the rotating rod from contacting the user's legs when sitting on the chair, and to prevent the tabletop from being inconvenient to rotate out. When the rotating rod rotates towards the bottom of the chair seat, the first telescopic rod and the tabletop are both located under the chair seat, so as not to increase the area occupied by the table and chair. When the rotating rod rotates out from the side of the chair seat, the second telescopic rod is rotated first, and then the second telescopic rod is extended and adjusted until the limit hook catches the limit ring. At this time, the first telescopic rod, the second telescopic rod and the tabletop form a triangle, so that the second telescopic rod is used to support the tabletop, improving the stability of the tabletop when in use.

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0019] A type of modular table and chairs, such as Figure 1 , Figure 2 and Figure 3 As shown, the chair includes a seat 1. A rotating rod 2, extending from the side of the seat 1, is rotatably connected to the bottom surface of the seat 1. A telescopic rod 1 is slidably connected along the length of the rotating rod 2. A table 3 is provided at the end of the telescopic rod 1 away from the rotating rod 2. A telescopic rod 2 is rotatably connected to the table 3. A limit ring 16 is welded to the end face of the telescopic rod 2. A limit hook 17 for hooking the limit ring 16 is welded to the outer wall of the telescopic rod 1. When the rotating rod 2 rotates towards the bottom surface of the seat 1, the telescopic rod 1 and the table 3 are both located below the seat 1, used to store the telescopic rod 1 and the table 3, and the table 3 does not contact the ground. When the user rotates the rotating rod 2 towards the side of the seat 1, it drives the telescopic rod 1 and the table 3, causing the rotating rod 2 to rotate 3 degrees. When both the telescopic rod 1 and the table 3 are rotated to the side of the seat 1, the axis of the table 3 is relatively parallel to the axis of the seat 1, and the rotating rod 2, the telescopic rod 1, and the table 3 are all in the extended state. At this time, the telescopic rod 1 can be rotated according to the user's usage habits. The sliding adjustment of lever 2 changes the horizontal distance between tabletop 3 and seat 1. Similarly, the user can adjust the relative height between tabletop 3 and seat 1 by extending and retracting telescopic lever 1. This allows the user to adjust the horizontal distance or height between tabletop 3 and seat 1 according to their usage habits. The rotation of lever 2 from the side of seat 1 prevents the lever 2 from contacting the user's legs when sitting on seat 1. When lever 2 rotates towards the bottom of seat 1, telescopic lever 1 and tabletop 3 are both located below seat 1, thus not increasing the area occupied by the table and chair. When lever 2 rotates out from the side of seat 1, telescopic lever 2 is rotated first, and then telescopic lever 2 is extended and retracted until limit hook 17 hooks limit ring 16. At this time, telescopic lever 1, telescopic lever 2 and tabletop 3 form a triangle, allowing telescopic lever 2 to support tabletop 3 and improve the stability of tabletop 3 during use.

[0020] like Figure 1 and Figure 2 As shown, the telescopic rod 2 includes a sleeve 2 18 and a connecting rod 2 19. The sleeve 2 18 is rotatably connected to the end face of the table 3. The limiting ring 16 is welded to the end face of the connecting rod 2 19 near the telescopic rod 1. The outer wall of the sleeve 2 18 has a threaded groove, and one end of the adjusting bolt passes through the threaded groove and abuts against the outer peripheral wall of the connecting rod 2 19. When the rotating rod 2 rotates to the side of the chair seat 1, the sleeve 2 18 is rotated first, and then the connecting rod 2 19 is slid in the sleeve 2 18 towards the telescopic rod 1 until the limiting hook 17 hooks the limiting ring 16. At this time, the bolt passes through the outer wall of the sleeve 2 18, so that the bolt abuts against the outer wall of the connecting rod 2 19. At this time, the telescopic rod 1, the telescopic rod 2, and the table 3 form a triangle, which improves the stability of the table 3 during use.

[0021] like Figure 1 As shown, the telescopic rod 1 has a through-hole 4 at the end near the rotating rod 2 to accommodate the rotating rod 2, and a positioning element 5, which is a bolt, is provided at the end near the rotating rod 2 to fix the two together. The telescopic rod 1 has a threaded hole for the bolt to pass through. One end of the bolt passes through the threaded hole and abuts against the outer peripheral wall of the rotating rod 2. First, the rotating rod 2 is rotated to the side of the chair seat 1 so that both the telescopic rod 1 and the chair seat 1 are in the extended state. At this time, the telescopic rod 1 slides on the outer peripheral wall of the rotating rod 2 through the through-hole 4. When the telescopic rod 1 slides towards the chair seat 1, it shortens the horizontal distance between the table 3 and the chair seat 1. When the telescopic rod 1 slides away from the chair seat 1, it increases the horizontal distance between the table 3 and the chair seat 1. When the telescopic rod 1 slides to the position desired by the user, the bolt passes through the threaded hole, so that one end of the bolt abuts against the outer peripheral wall of the rotating rod 2 to achieve sliding fixation of the telescopic rod 1. Moreover, the bolt can be used to fix the telescopic rod 1 at any sliding distance.

[0022] like Figure 1 and Figure 2As shown, the telescopic rod includes a sleeve 6 and a connecting rod 7 coaxially arranged. A limiting hook 17 is welded to the outer wall of the sleeve 6. One end of the connecting rod 7 is welded to the table 3. A through-hole 4 is opened on the sleeve 6. The end of the sleeve 6 away from the rotating rod 2 is provided with a positioning element 2 8 for fixing the connecting rod 7. The positioning element 2 8 is a bolt 2. The end of the sleeve 6 away from the rotating rod 2 is provided with a threaded hole 2 for the bolt 2 to pass through. One end of the bolt 2 passes through the threaded hole 2 and abuts against the outer peripheral wall of the connecting rod 7. When the rotating rod 1 is rotated to the side, the table 3 is in the unfolded state. At this time, the user can lower the height of the table 3 to the seat 1 by holding the connecting rod 7 and sliding it closer to the rotating rod 2 according to their own usage habits. When the connecting rod 7 slides to the desired length, the bolt 2 passes through the threaded hole 2, so that the end of the bolt 2 close to the connecting rod 7 abuts against the outer peripheral wall of the connecting rod 7 to achieve telescopic fixation of the connecting rod 7.

[0023] like Figure 1 and Figure 3 As shown, the bottom surface of the chair seat 1 has a receiving groove 9 for accommodating the rotating rod 2. The depth of the receiving groove 9 is greater than the thickness of the rotating rod 2. The bottom surface of the chair seat 1 has a fixing assembly for fixing the rotating rod 2. The fixing assembly includes a first pin seat 10 and a second pin seat 13, which are respectively fixed to one side of the receiving groove 9 by screws, and a first plug 11 and a second plug 14, which are fixed to the other side of the receiving groove 9 by screws. A first plug rod 12 for embedding into the first plug rod 11 is slidably connected to the first pin seat 10, and a second plug rod 15 for embedding into the second plug rod 14 is slidably connected to the second pin seat 13. When the rotating rod 2 is accommodated in the receiving groove 9, and the first telescopic rod and the table 3 are both located on the chair seat 1... When the rod is in the lower position, slide the first insertion rod 12 into the first plug 11. At this time, the outer wall of the first insertion rod 12 is in contact with the inner wall of the first plug 11, and the outer wall of the rotating rod 2 is pressed against the outer wall of the first insertion rod 12, so that the rotating rod 2 can be stably accommodated in the receiving groove 9. When it is necessary to rotate the rotating rod 2 out, first slide the first insertion rod 12 to disengage it from the first plug 11, and after rotating the rotating rod 2 out from the side of the seat 1, slide the second insertion rod 15 into the second plug 14. At this time, the outer wall of the second insertion rod 15 is in contact with the inner wall of the second plug 14, and the outer wall of the rotating rod 2 is pressed against the outer wall of the second insertion rod 15, which can improve the stability of the rotating rod 2 when it rotates to the side of the seat 1.
