[0047] The following will be combined with the appendix Figure 1 To be continued Figure 4 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0048] Please see Figure 3-4 This utility model embodiment provides a multifunctional adjustable dining chair, including:

[0049] The dining chair 1 consists of a seat 11 and a backrest 12. The seat 11 and the backrest 12 are rotatably coupled and used as a mounting carrier for the backrest assembly 2, adjustment assembly 3, footrest assembly 4, headrest assembly 5 and lifting assembly 6.

[0050] Adjustment component 3 is used for multi-angle flipping operation of backrest panel 12;

[0051] Adjustment component 3 includes:

[0052] The first rotating shaft 31 is rotatably connected to both sides of the seat plate 11, and the two first rotating shafts 31 are fixedly connected to the two ends of the rotating shaft of the backrest plate 12.

[0053] The second rotating shaft 32 is rotatably engaged with both sides of the dining chair 1, and the second rotating shaft 32 is located on one side of the first rotating shaft 31;

[0054] Stainless steel gears 33 are respectively installed on the shaft ends of the first rotating shaft 31 and the second rotating shaft 32, and the two stainless steel gears 33 are meshed and connected.

[0055] L-shaped plates 34 are installed on both sides of the base plate 11, and the L-shaped plates 34 are located above the stainless steel gear 33.

[0056] The bevel gears 35 are respectively installed on the shaft end of the second rotating shaft 32 and the bottom end of the L-shaped plate 34, and the two bevel gears 35 are meshed and connected.

[0057] Turntable 36 is mounted on the top of the rotating shaft set on L-shaped plate 34;

[0058] Insert rod 37, which slides in conjunction with turntable 36;

[0059] Slots 38 are equidistantly provided on the top of the outer side of the L-shaped plate 34, and multiple slots 38 cooperate with each other and inserts 37;

[0060] The slide 311 is formed at the bottom of the seat plate 11;

[0061] baffle 312, baffle 312 is slidably engaged with slide groove 311;

[0062] The limiting groove 39 is formed at the top of the inner wall of the slide groove 311;

[0063] The limiting block 310 slides with the limiting groove 39, and the bottom of the limiting block 310 is fixedly connected to the top of the baffle 312.

[0064] In practical application, when long hours of work are required, the turntable 36 is manually rotated to rotate the shaft on the L-shaped plate 34. This rotates the two bevel gears 35 on the shaft and the second shaft 32, respectively, which in turn rotates the two stainless steel gears 33 on the second shaft 32 and the first shaft 31. This causes the backrest 12 on the seat plate 11 to rotate from a 90-degree position to a position between 100 and 120 degrees. Then, the insert rod 37 is inserted into the slot 38 on the L-shaped plate 34 to lock the backrest 12 in its current position. When a lunch break is needed, the same operation is performed, and the backrest 12 on the seat plate 11 is rotated again until it is level with the seat plate 11.

[0065] This embodiment, by setting the adjustment component 3, facilitates multi-angle flipping of the backrest 12 on the seat 11, further making it suitable for staff in multiple scenarios, solving the problem of the single application scenario, improving the staff's experience, and further improving the practicality of the equipment, which is beneficial to actual application and operation.

[0066] In one embodiment, when the backrest 12 and the seat 11 are level, the weight of the seat 11 is greater than that of the backrest 12, so that the center of gravity of the dining chair 1 is on the seat 11, preventing the staff from leaning back and falling over when lying down, thus improving the stability of the equipment.

[0067] Please see Figure 4 In a preferred embodiment of this utility model, the back-attaching component 2 includes:

[0068] The first external thread rod 21 is threadedly engaged with the backrest plate 12.

[0069] The arc-shaped soft rubber plate 22 is rotatably engaged with the first external threaded rod 21;

[0070] The auxiliary rods 23 are all installed on the inner side of the arc-shaped soft rubber plate 22, and both auxiliary rods 23 are slidably engaged with the backrest plate 12.

[0071] In practical application, when it is necessary to adjust the support for the waist, the first external thread rod 21 is manually rotated, and the two auxiliary rods 23 are used to move the arc-shaped soft rubber plate 22, thereby improving the fit between the backrest 12 and the waist.

[0072] This embodiment provides back support component 2 to facilitate lumbar support for workers and further improves the fit between the backrest 12 and the waist.

[0073] Please see Figure 4 In a preferred embodiment of this utility model, the foot mounting component 4 includes:

[0074] Storage slot 41 is located on the side of seat plate 11 away from backrest plate 12;

[0075] The cavity 42 is located on one side of the inner wall of the storage slot 41;

[0076] Slide 43, slides into cavity 42;

[0077] Footrest 44 is slidably engaged with storage slot 41 and fixedly installed with slide plate 43.

[0078] In practical application, the footrest 44 is first manually pulled out from the inside of the storage slot 41, which drives the slide plate 43 to slide from the inside of the cavity 42 into the storage slot 41, so that the staff can place their feet flat on the footrest 44 when they rest.

[0079] This embodiment provides a footrest assembly 4, which allows workers to rest their feet on the footrest board 44 within the footrest assembly 4.

[0080] Please see Figure 4 In a preferred embodiment of this utility model, the headrest assembly 5 includes:

[0081] Elastic bandage 52;

[0082] The soft rubber pillow 51 is bound to the backrest 12 by elastic bandage 52.

[0083] In practical application, when staff need to use the dining chair 1, the soft rubber pillow 51 is slid up and down on the backrest 12 to adjust to a suitable position, and then the position of the soft rubber pillow 51 is fixed with the help of the elastic bandage 52 to protect the staff's head.

[0084] This embodiment provides a headrest assembly 5 to protect the worker's head and prevent it from hitting the backrest 12.

[0085] Please see Figure 4 In a preferred embodiment of this utility model, the lifting assembly 6 includes:

[0086] The internal thread grooves 61 are all opened on the four legs at the bottom of the base plate 11;

[0087] The second external thread rod 62 is threaded into the internal thread groove 61.

[0088] The anti-wear round pads 63 are all installed at the bottom end of the second external thread rod 62.

[0089] In practical application, according to the body proportions of each worker, the second external threaded rod 62 is manually rotated to drive the anti-wear round pad 63 to rotate, and at the same time, the internal threaded grooves 61 in the four support legs at the bottom of the dining chair 1 are raised, further driving the dining chair 1 to be raised and adjusted.

[0090] This embodiment uses a lifting component 6 to facilitate the adjustment of the height of the dining chair 1, making it more convenient for staff of different heights to use.

[0091] Based on the explanations and teachings in the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and any modifications and alterations to this utility model should also fall within the protection scope of the claims of this utility model.
