Description

Technical Field

[0001] This utility model relates to the technical field of table legs with automatic retraction and protection, specifically a folding table with automatic retraction and protection of table legs. Background Technology

[0002] Folding tables can be unfolded or folded as needed, achieving multiple uses. For example, a folding table can be stored away when not in use and unfolded as a workbench, dining table, or study table when needed, meeting different usage needs. The folding design makes the table easy to fold when not in use, making it convenient to move and store. It is especially suitable for families or offices that need to frequently change the furniture layout. Folding tables are usually designed with simplicity and a stylish appearance, which can be integrated into various home styles and enhance the overall aesthetics of the home.

[0003] A folding table, as disclosed in patent application CN211242114U, includes a tabletop and folding legs at one end of the tabletop. The other end of the tabletop is equipped with rollers, and a slide rail matching the rollers is mounted on a flat support. The flat support has an opening for storing the tabletop. When the tabletop is open, the rollers are located at the ends of the slide rails, supporting the tabletop together with the legs. When the tabletop is folded up, it moves along the slide rails via the rollers and folds into the opening of the flat support. The tabletop and the flat support together form a flat surface, and the legs are folded and stored within the opening of the flat support.

[0004] Although it achieves the goal of fixing the tabletop and legs to the flat support, it can prevent the folded tabletop from slipping off after being hit, thus improving the stability and safety of the table. Preventing the tabletop from slipping off can also reduce the wear and tear on the folding table's lifespan, improve the storage capacity of the folding table, and increase the space utilization efficiency of the folding table.

[0005] However, the existing tables with automatic leg retraction protection are not conducive to convenient multi-stage rotation and leg retraction during use. They are not easy to retract and unfold, and the height of the table is not easy to adjust. This greatly affects the space occupied by the table and the convenience of folding the legs.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] Please see Figure 1-7 This utility model provides an embodiment of a folding table with automatically retractable and protected legs, comprising a tabletop 1 and a disc 2. The disc 2 is disposed on the outside of the tabletop 1, and a U-shaped frame 3 is installed at the bottom of the tabletop 1. A lifting frame 9 is disposed on the outside of the U-shaped frame 3 below the disc 2. Two sets of connecting blocks 4 are symmetrically installed at the bottom of the tabletop 1 outside the U-shaped frame 3. A first shaft 20 is movably installed on the side wall of each connecting block 4. Table legs 5 are disposed on the outside of each connecting block 4. The table legs 5 are connected to the connecting blocks 4 through the first shaft 20. A second shaft 21 is movably installed on the side of each table leg 5 away from the connecting block 4. The outer side of the thigh 5 is provided with a table leg 6, which is connected to the thigh 5 via a second shaft 21. The inner side of the table leg 6 away from the thigh 5 is movably mounted with a third shaft 22. The outer side of the table leg 6 is provided with a foot 7, which is connected to the table leg 6 via the third shaft 22. One end of the first shaft 20, the second shaft 21, and the third shaft 22 is equipped with a worm gear 25. The connecting block 4 on one side of the worm gear 25, the outer wall of the thigh 5, and the table leg 6 are respectively equipped with a servo motor 23. The output end of the servo motor 23 is equipped with a worm 24, which meshes with the worm gear 25.

[0028] When automatic table leg retraction is required, multiple servo motors 23 are activated. The servo motors 23 drive the worm gear 24 to rotate. Under the meshing of the worm gear 24 and the worm wheel 25, the worm wheel 25 is driven to rotate. With the support of the connecting block 4, one set of worm wheels 25 drives the first shaft 20, the table leg 5, the table calf 6, and the machine foot 7 to rotate around the first shaft 20. With the support of the table leg 5, another set of worm wheels 25 drives the second shaft 21, the table calf 6, and the machine foot 7 to rotate around the second shaft 21. With the support of the table calf 6, another set of worm wheels 25 drives the third shaft 22 and the machine foot 7 to rotate around the third shaft 22. With the cooperation of multiple sets of rotations, the table legs can be automatically retracted. The same method facilitates the unfolding of the table legs. The height of the tabletop 1 can be easily adjusted by the range of the unfolded table legs. This realizes the convenient multi-level rotation cooperation for table leg retraction, which facilitates the convenient retraction and unfolding of the table legs, makes it easy to adjust the height of the table, reduces the space occupied by the table, and improves the convenience of table leg folding.

[0029] The U-shaped frame 3 is symmetrically equipped with first electric push rods 8 inside, and the output ends of the first electric push rods 8 are all connected to the lifting frame 9.

[0030] A support frame 10 is installed at the bottom of the lifting frame 9. A second electric push rod 11 is installed on the side wall of the support frame 10. A rack 12 is installed at the output end of the second electric push rod 11. A guide rail 15 is installed on the side wall of the rack 12. An L-shaped plate 13 is installed on the side of the bottom of the lifting frame 9 away from the support frame 10.

[0031] A slider 14 is installed on the side wall of the L-shaped plate 13. The slider 14 is slidably connected to the guide rail 15. A rotating shaft 17 is movably installed at the center of the inside of the lifting frame 9. The rotating shaft 17 extends through the lifting frame 9 to the outside of the lifting frame 9. The rotating shaft 17 is connected to the disc 2. A gear 16 is fitted on the surface of the rotating shaft 17 at the bottom of the lifting frame 9.

[0032] The rack 12 meshes with the gear 16. The top of the lifting frame 9 is equipped with four sets of equally spaced support seats 18. Rollers 19 are movably installed inside the support seats 18. The rollers 19 are slidably connected to the disc 2.

[0033] When the disc 2 is at the same height as the tabletop 1, it facilitates the use of the table on a flat surface. When it is necessary to raise the disc 2, the first electric push rod 8 is activated. Supported by the U-shaped frame 3, the first electric push rod 8 drives the lifting frame 9 to rise. The lifting frame 9, through the rotating shaft 17, drives the disc 2 to rise, so that the disc 2 leaves the surface of the tabletop 1. When it is necessary to rotate the disc 2, the second electric push rod 11 is activated. Supported by the support frame 10, the second electric push rod 11 drives the rack 12 to move. The rack 12 drives the guide rail 15 to move synchronously. Supported by the L-shaped plate 13 and the slider 14, and with the sliding cooperation between the slider 14 and the guide rail 15, the rack 12 drives the gear 16 to rotate. The gear 16 drives the rotating shaft 17 and the disc 2 to rotate, facilitating the circular rotation of items on the surface of the disc 2. This allows for convenient adjustment of the table's flatness, facilitates the lifting and rotating of items at the center of the table, and improves the table's visibility and practicality.

[0034] Working principle: When automatic table leg retraction is required, servo motor 23 drives worm gear 24 to rotate. The meshing of worm gear 24 and worm wheel 25 drives worm wheel 25 to rotate. Supported by connecting block 4, one set of worm wheels 25 drives the first shaft 20, table leg 5, table lower leg 6, and machine foot 7 to rotate around the first shaft 20. Supported by table leg 5, another set of worm wheels 25 drives the second shaft 21, table lower leg 6, and machine foot 7 to rotate around the second shaft 21. Supported by table lower leg 6, another set of worm wheels 25 drives the third shaft 22, and machine foot 7 to rotate around the third shaft 22. This multi-set rotation facilitates automatic table leg retraction and, in the same way, facilitates table leg unfolding. The height of the tabletop 1 can be easily adjusted by extending the table legs. When the disc 2 and the tabletop 1 are at the same height, the table can be used flat. When the disc 2 needs to be raised, the first electric push rod 8 drives the lifting frame 9 to rise. The lifting frame 9 drives the disc 2 to rise through the rotating shaft 17, so that the disc 2 leaves the surface of the tabletop 1. When the disc 2 needs to be rotated, the second electric push rod 11 drives the rack 12 to move. The rack 12 drives the guide rail 15 to move synchronously. The rack 12 drives the gear 16 to rotate. The gear 16 drives the rotating shaft 17 and the disc 2 to rotate, so that items on the surface of the disc 2 can rotate in a circular motion, thus completing the use of the table with automatic leg retraction and protection.
