[0018] Combined with appendix Figures 1 to 4 As shown, this embodiment discloses a flattenable and foldable table and chair, including a table module 1 and a chair module 2 located on the side of the table module 1. The chair module 2 includes a first chair part 201 and a second chair part 202. The first chair part 201 and the second chair part 202 include a chair support part 21 and a seat 22. The chair support part 21 includes a first support part 211 and a second support part 212. The seat 22 is fixed to the first support part 211. The table module 1 includes a table support part 11 and a tabletop 12. Either the second support part 212 or the table support part 11 can be telescopically moved within the other part, thereby changing the height of the table module 1. The first support part 211 is hinged to the bottom of the seat 22, and the table support part 11 is hinged to the bottom of the tabletop 12. In this embodiment, the table module 1 includes four table support parts 11, and the first chair part 201 or the second chair part 202 includes two chair support parts 21. Hinges are fitted under the seat 22 and the tabletop 12.

[0019] In conjunction with the above, the first chair portion 201 and the second chair portion 202 also include a connecting portion 213, which is used to connect the first support portion 211 and the second support portion 212. In this embodiment, the connecting portion 213, the first support portion 211, and the second support portion 212 adopt an integral molding structure. In other embodiments, the connecting portion 213, the first support portion 211, and the second support portion 212 may also adopt a separate molding structure, such as a splicing structure or an embedded connection structure.

[0020] In conjunction with the above, the first chair part 201 and the second chair part 202 may adopt the same structure or different structures. In this embodiment, the first chair part 201 and the second chair part 202 adopt the same structure, and the first chair part 201 and the second chair part 202 are respectively arranged on opposite sides of the table module 1. The table support part 11 is provided with a telescopic cavity, and the second support part 212 can move in the telescopic cavity. When the table module 1 is extended to a set height, the folding table and chair are in the unfolded state. When the height of the tabletop 12 is the same as or slightly higher than the height of the chair surface 22, the folding table and chair are in the flat state. In other embodiments, the table support part 11 can also telescopically move inside the second support part 212.

[0021] In conjunction with the above, the system also includes a diagonal bracing assembly 3. The diagonal bracing assembly 3 includes a main connecting rod 31 and several side connecting arms 32. One end of the main connecting rod 31 is hinged to the center of the tabletop 12, and the other end is hinged to one end of a side connecting arm 32. The other end of each side connecting arm 32 is hinged to either the table support 11 or the second support 212. Preferably, in this embodiment, a mounting beam with a hinged seat is provided below the tabletop 12, and the end of the main connecting rod 31 is fitted with the hinged seat of the mounting beam. There are two side connecting arms 32, respectively located on both sides of the main connecting rod 31 and extending outwards, forming a "Y"-shaped structure with the diagonal bracing assembly 3. The other end of each side connecting arm 32 is hinged to the table support 11. In other embodiments, the other end of the side connecting arm 32 may also be hinged to the second support 212.

[0022] In conjunction with the above installation structure, the diagonal brace assembly 3 also includes a first locking part 33. The first locking part 33 can move along the main connecting rod 31. When the first locking part 33 moves to the hinge point between the main connecting rod 31 and the side connecting arm 32, the first locking part 33 and the side connecting arm 32 form a limiting lock, so that when the folding table and chair are in the unfolded or flattened state, the chair support part 21 can remain perpendicular to the ground, preventing the chair support part 21 from suddenly swinging inward to fold. Preferably, in this embodiment, the first locking part 33 is a sliding sleeve structure sleeved on the main connecting rod 31.

[0023] In conjunction with the above, it also includes a second locking part 13. After the height of the table support part 11 is adjusted, the second locking part 13 is used to fix the table support part 11 and the second support part 212, so that the height of the table module 1 remains fixed.

[0024] In this embodiment, based on the above installation structure, the second locking part 13 includes a knob 131 and a locking rod 132. Both the second support part 212 and the table support part 11 are provided with locking holes. Rotating the knob 131 allows the locking rod 132 to pass through the locking holes and fix the table support part 11 and the second support part 212. In one embodiment, the second support part 212 and the table support part 11 may be provided with multiple spaced-apart locking holes, allowing the table module 1 to be fixed at different heights, thereby meeting the user's need to freely adjust the table height. In other embodiments, other common locking structures in the prior art can also be used.

[0025] Based on the above installation structure, the usage process of this utility model is as follows: When it is necessary to fold the folding table and chair, first release the second locking part 13 from fixing the table support part 11 and the second support part 212, then adjust the height of the table module 1 downwards to make the folding table and chair flat, then move the first locking part 33 from the hinge point of the main connecting rod 31 and the secondary connecting arm 32 to any position in the middle of the main connecting rod 31, release the limiting lock on the secondary connecting arm 32, and finally swing the chair support part 21 inwards to realize the folding of the folding table and chair.

[0026] Similarly, by reversing the steps described above, the folding table and chair can be unfolded.

[0027] This utility model has a simple structure, is convenient to fold, occupies little space after folding, and can flatten tables and chairs for transportation, reducing production and transportation costs. When unfolded, it has good structural stability and is sturdy and durable.

[0028] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
