Description

Technical Field

[0001] The present application relates to the field of furniture, and in particular to a dining table with a turntable. Background Art

[0002] At present, in order to facilitate diners to conveniently eat food on the dining table, a dining table turntable is installed on the dining table. When in use, food is placed on the dining table turntable, and the food is moved by rotating the dining table turntable relative to the dining table, so that diners can eat conveniently.

[0003] However, the existing built-in dining table turntable is almost embedded in the dining table top, so the gap between the dining table turntable and the dining table top is small. If an object enters between the two, it is difficult to take it out.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there is a defect that it is difficult to take out the items between the dining table turntable and the dining table top. Summary of the invention

[0005] In order to facilitate taking out items between the turntable and the tabletop, the present application provides a dining table with a turntable, which adopts the following technical solution:

[0006] A dining table with a turntable comprises a tabletop and a turntable, wherein a rotating shaft is rotatably connected inside the tabletop, a screw is provided at the lower end of the turntable, and the screw is threadedly connected to the rotating shaft, and a brake assembly for braking the rotating shaft is installed on the lower end surface of the tabletop; when the brake assembly brakes the rotating shaft, the resistance that needs to be overcome when the rotating shaft rotates relative to the tabletop is greater than the resistance that needs to be overcome when the screw rotates relative to the rotating shaft; when the brake assembly does not brake the rotating shaft, the resistance that needs to be overcome when the rotating shaft rotates relative to the tabletop is less than the resistance that needs to be overcome when the screw rotates relative to the rotating shaft.

[0007] By adopting the above technical solution, during daily use, the brake assembly does not brake the shaft. At this time, the resistance that needs to be overcome when the shaft rotates relative to the table is less than the resistance that needs to be overcome when the screw rotates relative to the shaft. When the turntable rotates, the shaft rotates relative to the table, and the height of the turntable relative to the table remains unchanged, so that the turntable can be used normally. If it is necessary to take out items between the turntable and the table, the brake assembly can be used to brake the shaft. At this time, the resistance that needs to be overcome when the shaft rotates relative to the table is greater than the resistance that needs to be overcome when the screw rotates relative to the shaft. When the turntable rotates, the shaft does not move relative to the table, and the turntable rotates relative to the shaft. At this time, under the action of the screw, the turntable rotates and rises and falls, thereby changing the size of the gap between the turntable and the table, which is convenient for taking out items or daily cleaning.

[0008] At the same time, according to the actual practical needs of the user, the turntable can be adjusted to a certain height and then the brake assembly can be released. At this time, the resistance that the shaft needs to overcome when rotating relative to the table is smaller than the resistance that the screw needs to overcome when rotating relative to the shaft. When the turntable rotates, the shaft rotates relative to the table, and the height of the turntable relative to the table remains unchanged, so that the turntable can be used normally. In this way, the dining table can be suitable for users with different needs.

[0009] Preferably, the outer fixed sleeve of the rotating shaft is provided with a rotating shaft sleeve, and the brake assembly includes a brake pad; the brake assembly brakes the rotating shaft by pressing the brake pad against the rotating shaft sleeve.

[0010] By adopting the above technical solution, the part of the rotating shaft that needs to be braked is thickened by the rotating shaft sleeve, thereby preventing the probability of the rotating shaft being deformed due to braking by the brake pad.

[0011] Preferably, the brake assembly also includes a brake line and a tension spring, the brake pad is slidably connected to the table top, one end of the brake line is fixedly connected to the brake pad, the brake line is used to drive the brake pad close to the rotating shaft sleeve, one end of the tension spring is connected to the brake pad and the other end is connected to the table top, and the tension spring is used to drive the brake pad to return to a state away from the rotating shaft sleeve.

[0012] By adopting the above technical solution, when the rotating shaft needs to be braked, the brake line drives the brake pad to move relative to the rotating shaft until it is pressed against the rotating shaft, thereby increasing the resistance that the rotating shaft needs to overcome when rotating relative to the table. When braking is not needed, the brake line is released, and the brake pad is reset to a position that does not contact the rotating shaft under the action of the tension spring, thereby reducing the resistance that the rotating shaft needs to overcome when rotating relative to the table.

[0013] Preferably, the brake pad is arc-shaped, one end of the brake pad is rotatably connected to the tabletop, and the brake line is fixedly connected to the free end of the brake pad.

[0014] By adopting the above technical solution, the brake pad can be more stably approached and away from the rotating shaft.

[0015] Preferably, a receiving groove is provided on the table top, and the rotating shaft is rotatably connected to the receiving groove via a bearing group.

[0016] By adopting the above technical solution, the rotating shaft can smoothly rotate relative to the desktop.

[0017] Preferably, the bearing group includes a large bearing and a small bearing, and the large bearing and the small bearing are respectively located at two ends of the rotating shaft.

[0018] By adopting the above technical solution, the coaxiality of the turntable during rotation is ensured through the large and small bearing design and the upper and lower bearing design. At the same time, the up and down fluctuations during rotation are reduced, thereby reducing the problem of table surface scratches.

[0019] Preferably, the desktop includes a functional frame and a table top installed on the functional frame, the table top is provided with a circular groove for embedding a turntable, the screw is threadedly connected to the functional frame, a positioning shaft is coaxially fixed on the upper end of the screw, a positioning groove is provided on the turntable, the positioning shaft is inserted into the positioning groove and has an interference fit with the positioning groove.

[0020] By adopting the above technical solution, the axial positioning function is realized through the cooperation of the positioning groove and the positioning shaft, so that the gaps between the desktop and the turntable are uniform at various locations, and the turntable is made as stable as possible when rotating.

[0021] Preferably, a first adjusting screw is rotatably connected to the functional frame, and the first adjusting screw passes through the functional frame and is threadedly connected to the table top. At least two first adjusting screws are provided along the circumference of the table top.

[0022] By adopting the above technical solution, the distance between the table top and the functional frame can be adjusted by screwing each first adjusting screw, so that the entire upper end surface of the table top can be located at the same height as much as possible and tend to be completely flat.

[0023] Preferably, at least two first adjusting screws are provided along the radial direction of the rotating disk.

[0024] By adopting the above technical solution, the table top has more connection points, so that the table top can be installed on the functional frame more stably.

[0025] Preferably, a positioning pin is threadedly connected to the functional frame, and the positioning pin passes through the functional frame and abuts against the table top.

[0026] By adopting the above technical solution, the positioning pin cooperates with the first adjusting screw, the first adjusting screw drives the table top to move toward the functional frame, and the positioning pin drives the table top to move away from the functional frame, so that the table top is limited up and down and stably installed on the functional frame.

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1-8 This application is described in further detail.

[0042] The present application embodiment discloses a dining table with a turntable. Figure 1 and Figure 2 The dining table includes a tabletop 1, a turntable 2 and a support column 3. The tabletop 1 includes a function frame 4 and a tabletop 5 mounted on the function frame 4. The tabletop 5 is provided with a circular groove 6 for embedding the turntable 2. The turntable 2 is embedded in the circular groove 6 and rotatably connected to the function frame 4. The support column 3 is fixedly connected to the lower end surface of the function frame 4 and is used to support the function frame 4.

[0043] When in use, the dishes can be placed on the turntable 2, the tableware can be placed on the table board 5, and then the turntable 2 can be rotated relative to the table board 5 until the desired dishes are in front of the user.

[0044] Reference Figure 3 In order to make the upper end surface of the table top 5 as flat as possible, the functional frame 4 is in a cross shape. Figure 2 and Figure 4 The function frame 4 is rotatably connected with a first adjusting screw 7, which passes through the function frame 4 and is threadedly connected to the table board 5. Four first adjusting screws 7 are arranged along the circumference of the table board 5. Two first adjusting screws 7 are arranged along the radial direction of the turntable 2. That is, two first adjusting screws 7 are arranged at each end of the function frame 4. Figure 3 and Figure 4 The function frame 4 is threadedly connected with a positioning nail 8, which passes through the function frame 4 and abuts against the table board 5. Four positioning nails 8 are arranged along the circumference of the table board 5. Three positioning nails 8 are arranged along the radial direction of the turntable 2. That is, three positioning nails 8 are arranged at each end of the function frame 4.

[0045] By screwing the first adjusting screws 7, the distance between the table top 5 and the functional frame 4 can be adjusted, so that the entire upper end surface of the table top 5 is at the same height as much as possible and tends to be completely flat. The positioning nails 8 can support the table top 5, so that the table top 5 is limited in position both up and down and stably installed on the functional frame 4.

[0046] Reference Figure 2 and Figure 5 The turntable 2 includes a mounting portion 10 and a rotating table 11, and the mounting portion 10 is rotatably connected to the functional frame 4. The mounting portion 10 is rotatably connected to a second adjusting screw 9, which passes through the mounting portion 10 and is threadedly connected to the rotating table 11. Four second adjusting screws 9 are provided along the circumference of the rotating table 11. By screwing each second adjusting screw 9, the distance between the mounting portion 10 and the rotating table 11 is adjusted, so that the entire upper end surface of the rotating table 11 is at the same height as much as possible and tends to be completely flat.

[0047] Reference Figure 3 and Figure 6 In order to facilitate the cleaning between the turntable 2 and the table top 5, the turntable 2 can move in the vertical direction relative to the table top 1. Specifically, a screw 12 is provided at the lower end of the mounting portion 10. A positioning shaft 13 is coaxially fixedly provided at the upper end of the screw 12. The mounting portion 10 is provided with a positioning groove 14. The positioning shaft 13 is inserted into the positioning groove 14 and is interference fit with the positioning groove 14. Thus, the mounting portion 10 is fixedly connected to the screw 12. The screw 12 is externally threaded with a rotating shaft 24. A receiving groove 25 is provided on the functional frame 4, and the rotating shaft 24 is rotatably connected to the receiving groove 25 through a bearing group 15. The bearing group 15 includes a large bearing 16 and a small bearing 17. The large bearing 16 is installed at the upper end of the rotating shaft 24, and the small bearing 17 is installed at the lower end of the rotating shaft 24. The outer fixed sleeve of the rotating shaft 24 is provided with a rotating shaft sleeve 18, and a fastening bolt 19 is threadedly connected to the rotating shaft sleeve 18, and the fastening bolt 19 is pressed against the outer wall of the rotating shaft 24, so that the rotating shaft sleeve 18 is fixedly installed on the rotating shaft 24. A brake assembly 20 is installed on the functional frame 4, and the brake assembly 20 increases the resistance that needs to be overcome when the rotating shaft 24 rotates by pressing against the rotating shaft sleeve 18.

[0048] In daily use, the brake assembly 20 does not brake the shaft 24. At this time, the resistance that the shaft 24 needs to overcome when rotating relative to the functional frame 4 is smaller than the resistance that the screw 12 needs to overcome when rotating relative to the shaft 24. When the turntable 2 rotates, the shaft 24 rotates relative to the table 1, and the height of the turntable 2 relative to the table 1 remains unchanged, so that the turntable 2 can be used normally.

[0049] If it is necessary to take out the items between the turntable 2 and the table top 1, the brake assembly 20 can be used to brake the shaft 24. At this time, the resistance that the shaft 24 needs to overcome when rotating relative to the table top 1 is greater than the resistance that the screw 12 needs to overcome when rotating relative to the shaft 24. When the turntable 2 rotates, the shaft 24 does not move relative to the table top 1, and the turntable 2 rotates relative to the shaft 24. At this time, under the action of the screw 12, the turntable 2 rotates and rises, thereby changing the size of the gap between the turntable 2 and the table top 1. Figure 7 As shown, it is convenient for taking out items or daily cleaning.

[0050] Reference Figure 3 and Figure 8 The brake assembly 20 includes a brake pad 21, a brake line 22 and a tension spring 23. The brake pad 21 is in an arc shape, one end of the brake pad 21 is rotatably connected to the functional frame 4, and the other end is fixedly connected to the brake line 22. The brake line 22 is fixedly installed on the functional frame 4. The brake line 22 is used to drive the brake pad 21 to approach the rotating shaft sleeve 18. One end of the tension spring 23 is connected to the brake pad 21 and the other end is connected to the functional frame 4. The tension spring 23 is used to drive the brake pad 21 to return to a state away from the rotating shaft sleeve 18.

[0051] When the rotating shaft 24 needs to be braked, the brake line 22 drives the brake pad 21 to rotate relative to the functional frame 4 until it abuts against the rotating shaft sleeve 18, thereby increasing the resistance that the rotating shaft 24 needs to overcome to rotate relative to the table 1. When braking is not needed, the brake line 22 is released, and the brake pad 21 is reset to a position where it does not contact the rotating shaft sleeve 18 under the action of the tension spring 23, thereby reducing the resistance that the rotating shaft 24 needs to overcome to rotate relative to the functional frame 4.

[0052] The implementation principle of the dining table with a turntable 2 in the embodiment of the present application is:

[0053] 1. The brake assembly 20 is used to change the resistance that the rotating shaft 24 needs to overcome when rotating relative to the functional frame 4, so that the dining table can be switched between two states;

[0054] 2. In state 1, the resistance that the rotating shaft 24 needs to overcome when rotating relative to the functional frame 4 is smaller than the resistance that the screw 12 needs to overcome when rotating relative to the rotating shaft 24. When the turntable 2 rotates, the rotating shaft 24 rotates relative to the desktop 1, and the height of the turntable 2 relative to the desktop 1 remains unchanged, so that the turntable 2 can be used normally;

[0055] 3. In state 2, the resistance that the rotating shaft 24 needs to overcome when rotating relative to the functional frame 4 is greater than the resistance that the screw 12 needs to overcome when rotating relative to the rotating shaft 24. When the turntable 2 rotates, the rotating shaft 24 does not move relative to the desktop 1, and the turntable 2 rotates relative to the rotating shaft 24. At this time, under the action of the screw 12, the turntable 2 rotates and rises and falls, thereby changing the size of the gap between the turntable 2 and the desktop 1, which is convenient for taking out items or daily cleaning;

[0056] 4. The first adjusting screw 7 and the second adjusting screw 9 can be used to keep the upper end surface of the table top 5 and the upper end surface of the rotating table top 11 as flat as possible;

[0057] 5. The bearing assembly 15 can reduce the up and down fluctuation of the turntable 2 when it rotates relative to the table 1, so that the turntable 2 can rotate more stably.

[0058] 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.
