Description

Technical Field

[0001] This utility model relates to the field of dining table technology, specifically to a dining table with an adjustable seat. Background Technology

[0002] Dining chairs and dining tables are combined to form a dining chair and table combination. The two together can provide people with a certain dining environment and are mostly used in indoor environments.

[0003] A prior art dining table, such as the invention patent document with authorization publication number "CN222264715U" and patent name "A Canteen Dining Table Storage Box," discloses a dining table including a dining table and a storage box. Multiple seats are fixedly connected to the side of the dining table via longitudinal beams, and the seats are spaced apart. The storage box is detachably connected to the longitudinal beams between the spaced sections via a connecting device. Preferably, the longitudinal beams are made of iron, and the connecting device has a slot in which a bar magnet is fitted. The bar magnet is retractable and fitted into the slot.

[0004] The positions of the dining table and chairs in the aforementioned patent documents are relatively fixed, and users cannot adjust the distance between the chairs and the table according to their own needs. This may result in users being too far away or too close to the table when sitting, reducing the user's experience. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by proposing a dining table with an adjustable seat. This addresses the technical problem mentioned in the background art, where the positions of the dining table and chairs are relatively fixed, preventing users from adjusting the distance between the chair and the table according to their needs. This could result in users being too far or too close to the table, thus reducing their user experience.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: it includes a support frame, a dining board on the top of the support frame, a plurality of hollow support rods fixed on the side wall of the support frame, a connecting rod slidably provided in each of the plurality of support rods, a seat plate for sitting fixed on the plurality of connecting rods, an adjustment component for adjusting the position of the connecting rod in the support rod in each support rod, and a limiting component for limiting the rotation of the adjustment component on each support rod.

[0007] Working principle: When the user needs to adjust the seat position, they operate the adjustment components associated with each support rod. Once the adjustment components are driven, their power is transmitted to the connecting rods that are slidably installed inside the hollow support rods. The connecting rods move linearly within the cavity of the support rods, thereby changing their length extending into or out of the support rods. After the seat is adjusted to the desired position by the movement of the connecting rods, the user operates the limiting components associated with each support rod. These limiting components act on the adjustment components, preventing them from continuing to rotate or move, thereby locking the relative position between the connecting rods and the support rods. Under the action of the limiting components, the positions of the connecting rods and the seat fixed to them are fixed, ensuring stability during riding.

[0008] Compared with the prior art, the present invention has the following beneficial effects: By combining the adjustment and restraint components, users can flexibly adjust the distance between the seat and the dining table according to their body shape, comfort needs, or the specific scenario of using the dining table. The adjustment mechanism is directly set on the side wall of the support frame, making the seat and the dining table a whole. Compared with independently set dining chairs, this saves space and avoids the cluttered layout caused by moving the chairs separately. Attached Figure Description

[0011] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0012] Example: like Figure 1 and Figure 2 and Figure 5As shown, a dining table with an adjustable seat includes a support frame 1. A tabletop 2 is mounted on the top of the support frame 1. Two hollow support columns 17 are fixed to the top of the support frame 1, and two connecting columns 18 are fixed to the bottom of the tabletop 2. The two connecting columns 18 are slidably disposed within the two support columns 17. Several through holes 19 are formed along the length of each of the two connecting columns 18. Bolts 20 are slidably inserted into each of the two support columns 17. Each bolt 20 can slide through one of the through holes 19 on the two connecting columns 18 and extend outward from the support column 17. Nuts 21 are screwed to the ends of both bolts 20. When the height of the serving board 2 needs to be adjusted, the user first loosens the nuts 21 on the two side support columns 17, and pulls the serving board 2 up or down. The serving board 2 slides in the hollow support column 17 at the top of the support frame 1 through the connecting column 18 at the bottom. When the serving board 2 moves to the ideal height and a certain through hole 19 on the connecting column 18 is aligned with the bolt 20 hole on the support column 17, the bolt 20 is passed through the through hole 19, and then the nut 21 is tightened at the protruding end of the bolt 20. Through the radial tension of the bolt 20 and the axial locking force of the nut 21, the connecting column 18 and the support column 17 are firmly fixed together, thereby completing the height adjustment and locking of the serving board 2.

[0013] like Figure 1 and Figure 3 As shown, several hollow support rods 3 are fixed on the side wall of the support frame 1. Connecting rods 4 are slidably installed inside each of the support rods 3. Seats 5 for sitting are fixed on each of the connecting rods 4. Each support rod 3 has an adjustment component for adjusting the position of the connecting rod 4 within the support rod 3. The adjustment component includes a first rotating shaft 6, a first gear 7, and a rack 8. The first rotating shaft 6 is rotatably installed inside the support rod 3. The first gear 7 is fixed on the first rotating shaft 6. The rack 8 is fixed on the connecting rod 4 and meshes with the first gear 7. By rotating the fixed rod 14 in the limiting component, the user ultimately transmits power to the first rotating shaft 6 in the adjustment component. The rotation of the first rotating shaft 6 drives the first gear 7 on it to rotate synchronously. Since the first gear 7 meshes with the rack 8 fixed on the connecting rod 4, the rotational motion of the gear is converted into the linear motion of the rack 8. The linear motion of the connecting rod 4 drives the seat 5 fixed to it to move forward or backward together, thereby realizing the adjustment of the position of the seat 5.

[0014] like Figure 1 and Figure 4As shown, each of the support rods 3 is provided with a limiting component for restricting the rotation of the adjustment assembly. The limiting component includes a second rotating shaft 9, two second gears 10, a worm gear 11, and a worm 12. The second rotating shaft 9 is rotatably disposed inside the support rod 3 and one end slides through the support rod 3 and extends outward. The two second gears 10 are respectively fixed on the first rotating shaft 6 and the second rotating shaft 9, and the two second gears 10 mesh with each other. The worm gear 11 is fixed on the second rotating shaft 9 and located outside the support rod 3. The worm 12 is rotatably disposed on the support rod 3 and meshes with the worm gear 11. A disk 13 is fixedly disposed at the end of the worm 12. A fixing rod 14 is fixedly disposed on the disk 13. Several insertion interfaces 15 are opened on the circumference of the disk 13. A insertion rod 16 slides through the support rod 3, and the end of the insertion rod 16 can abut against one of the insertion interfaces 15 on the disk 13.

[0015] like Figure 1 and Figure 4 As shown, the user rotates the fixed rod 14, causing the disc 13 and the worm gear 12 to rotate together. The worm gear 12 drives the worm wheel 11, which meshes with it, to rotate. The rotation of the worm wheel 11 transmits the motion to the first rotating shaft 6 through the second rotating shaft 9 and a pair of meshing second gears 10 on it, thereby driving the aforementioned adjustment components to work. When the fixed rod 14 stops rotating, thanks to the reverse self-locking characteristics of the worm wheel 11 and the worm gear 12, the entire transmission system will be automatically locked, and the position of the seat plate 5 will be initially fixed and will not retract under pressure. After adjustment, the plug rod 16 is pushed into the corresponding plug interface 15 on the disc 13, thereby achieving mechanical locking.

[0016] Working principle: When the user needs to adjust the front and rear position of the seat plate 5, the worm gear 12 and the disc 13 can be rotated by the fixed rod 14. The worm gear 12 drives the worm wheel 11. The power is transmitted to the first rotating shaft 6 through the second rotating shaft 9 and a pair of meshing second gears 10, causing the first gear 7 on it to rotate. The first gear 7 meshes with the rack 8 fixed on the connecting rod 4, thereby converting the rotational motion into linear motion, driving the connecting rod 4 to slide in the support rod 3, and finally driving the seat plate 5 to extend or retract. After the adjustment is in place, the worm wheel 11 and worm gear 12 mechanism achieves initial locking by using its reverse self-locking characteristic. At this time, the plug rod 16 is pushed into the corresponding plug interface 15 on the disc 13 to achieve double mechanical locking. At the same time, the height of the dining plate 2 can also be adjusted independently. After the user loosens the nut 21, the user can pull the dining plate 2 so that the connecting post 18 at the bottom slides in the support post 17 to the required height. Then, the bolt 20 passes through the corresponding through hole 19 on the connecting post 18 and the nut 21 is tightened to complete the fixing of the dining plate 2.

[0017] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
