Detailed implementation mode

[0029] This detailed implementation mode is an electric combined locker telescopic dining table, and its structural schematic diagram is as Figure 1-6 shown. The telescopic dining table includes the main body 1 of the dining table; a support platform 2 is provided on the top of the main body 1 of the dining table, extension boards 3 are provided on both sides of the support platform 2, and a rotating table 4 is rotatably connected to the top of the support platform 2. An extension unit is provided at the bottom of the support platform 2 on the top of the main body 1 of the dining table, and a storage box 5 is provided at the bottom of the main body 1 of the dining table. A storage cavity 6 is opened inside the storage box 5. Support frames 7 are provided on both sides of the main body 1 of the dining table and at the bottom of the two groups of extension boards 3. Two groups of seats 8 are provided inside the support frames 7. When the main body 1 of the dining table is in use, through the cooperation of the storage box 5 and the storage cavity 6, the main body 1 of the dining table can have a storage function. When the meals are placed on the main body 1 of the dining table, the meals are placed on the top of the rotating table 4. The rotating table 4 extends into the support platform 2 and is fixedly connected to the driving end of a driving motor. Through the driving motor, the rotating table 4 is driven to rotate, so that the meals on its top can be displaced, thereby facilitating the picking up of the meals.

[0030] The extension unit is composed of an extension component 9 and a guiding component 10. The extension component 9 is used to drive the two groups of extension boards 3 to perform extension processing, and the guiding component 10 is used for the guiding processing of the extension boards 3.

[0031] Among them, in this embodiment, the extension component 9 is composed of a connecting frame 11, a rotating block 12, a rotating rod 13, a moving block 14, a compression spring 15 and a moving rod 16. The connecting frame 11 is located on the top of the main body 1 of the dining table and at the bottom of the support platform 2. The rotating block 12 is rotatably connected inside the connecting frame 11. Two groups of rotating rods 13 are respectively rotatably connected to both ends of the rotating block 12. The moving block 14 is located at the end of the rotating rod 13 away from the rotating block 12. The compression spring 15 is located at the end of the moving block 14 away from the rotating rod 13. Two groups of moving rods 16 are respectively slidably connected to both ends of the connecting frame 11. When it is necessary to perform extension processing on the extension board 3, the extension board 3 can be extended through the extension component 9.

[0032] Secondly, in this embodiment, a receiving groove 17 is formed inside the connecting frame 11 and outside the compression spring 15. The internal structure size of the receiving groove 17 corresponds to the external structure size of the moving block 14. The moving block 14 is connected to the compression spring 15 through the receiving groove 17, and the connecting frame 11 is connected to the compression spring 15 through the receiving groove 17. Connecting the compression spring 15 to the receiving groove 17 enables the compression spring 15 to be connected to the connecting frame 11. When the compression spring 15 drives the moving block 14 to displace, the stability of its displacement can be increased. The moving block 14 is slidably connected to the receiving groove 17, so that the moving block 14 can be slidably connected to the connecting frame 11. When the moving block 14 displaces, the stability of its displacement can be increased through the receiving groove 17. When the expansion plate 3 needs to be expanded, the compression spring 15 drives the moving block 14 to displace, so that the rotating rod 13 can displace;

[0033] In addition, in this embodiment, one end of the moving rod 16 away from the connecting frame 11 is fixedly connected to the expansion plate 3. A sliding block 18 is provided at one end of the expansion plate 3 close to the support table 2. Sliding grooves 19 are formed at both ends of the support table 2 close to the two expansion plates 3. The internal structure size of the sliding groove 19 corresponds to the external structure size of the sliding block 18. The expansion plate 3 is connected to the sliding groove 19 through the sliding block 18. The sliding block 18 is slidably connected to the sliding groove 19, so that the expansion plate 3 can be slidably connected to the support table 2. When the expansion plate 3 displaces, the stability of its displacement can be increased through the sliding connection between the sliding block 18 and the sliding groove 19, preventing deviation;

[0034] Furthermore, in this embodiment, the guiding component 10 is composed of a fixed frame 20, a guiding rod 21, a meshing groove 22, a first gear 23, a connecting rod 24 and a second gear 25. The two fixed frames 20 are respectively located at both ends of the connecting frame 11. The guiding rod 21 is slidably connected inside the fixed frame 20. Multiple meshing grooves 22 are formed on the outer side of the guiding rod 21. The first gear 23 is rotatably connected inside the fixed frame 20 and outside the meshing groove 22. The connecting rod 24 is fixedly connected to the inside of the first gear 23. The second gear 25 is fixedly connected to one end of the connecting rod 24 away from the first gear 23. When the expansion plate 3 displaces, the guiding component 10 can guide the expansion plate 3, thereby increasing the stability of the displacement of the expansion plate 3 and preventing deviation;

[0035] Furthermore, in this embodiment, the internal structure size of the engagement groove 22 is designed to correspond to the external structure size of the first gear 23. The first gear 23 is connected to the guide rod 21 through the engagement groove 22. Inside the fixed frame 20 and outside the guide rod 21, there is a fixed plate 26. The guide rod 21 is slidably connected to the fixed plate 26, and a limit block 27 is provided at one end of the guide rod 21 away from the engagement groove 22. When the guide rod 21 is displaced to a specified position, the guide rod 21 can be limited by the cooperation of the limit block 27 and the fixed plate 26 to prevent the guide rod 21 from shifting, which may affect the overall use. The extension plate 3 is connected to the fixed frame 20 through the guide rod 21. The first gear 23 is engaged with the engagement groove 22, so that the first gear 23 can be connected to the guide rod 21. When the guide rod 21 is displaced, the first gear 23 can guide it, and the connecting rod 24 is limited by the second gear 25, so that the connecting rod 24 limits the first gear 23. Thus, the first gear 23 can limit the guide rod 21 through the engagement groove 22 to prevent the guide rod 21 from moving, which may affect the storage of the extension plate 3;

[0036] Furthermore, in this embodiment, a limit rod 28 is rotatably connected to one end of the fixed frame 20 close to the second gear 25. A third gear 29 is fixedly connected to the outside of the limit rod 28. The third gear 29 is engaged with the second gear 25. One end of the limit rod 28 away from the third gear 29 extends outside the fixed frame 20 and is fixedly connected to a limit gear 30. A clamping block 31 is provided outside the limit gear 30. The clamping block 31 is rotatably connected to the fixed frame 20, and the external structure size of the clamping block 31 is designed to correspond to the internal structure size of the limit gear 30. The outside of the clamping block 31 is in contact with the inside of the limit gear 30, so that the clamping block 31 can limit the limit gear 30. Thus, the limit gear 30 can limit the connection of the limit rod 28 and limit the third gear 29. Cooperating with the engaged second gear 25, the connecting rod 24 can be limited;

[0037] Furthermore, in this embodiment, a clamping rod 32 is provided at one end of the clamping block 31 away from the limit gear 30. The clamping rod 32 is rotatably connected to the fixed frame 20, and the clamping rod 32 is connected to the fixed frame 20 through a torsion spring. By connecting the clamping rod 32 with the torsion spring, the torsion spring can limit the clamping rod 32, so that the clamping rod 32 can limit the connection of the clamping block 31 and limit the clamping block 31 inside the limit gear 30;

[0038] Furthermore, in this embodiment, a fixing groove 33 is provided at the bottom of the seat 8. Fixing blocks 34 are provided at both ends of the support frame 7 close to the two groups of seats 8. The external structure size of the fixing block 34 corresponds to the internal structure size of the fixing groove 33. The seat 8 is connected through the fixing groove 33 and the fixing block 34. Connecting the fixing groove 33 and the fixing block 34 enables the seat 8 to be connected with the fixing block 34 in a limiting manner, so that the seat 8 can be stored inside the support frame 7 and can be conveniently used when the seat 8 is needed.

[0039] When using the device of this technical solution, when the table body 1 is in use, through the cooperation of the storage box 5 and the storage cavity 6, the table body 1 can have a storage function. When the meals are placed on the table body 1, the meals are placed on the top of the rotating table 4. The rotating table 4 extends into the support table 2 and is fixedly connected to the driving end of the driving motor. Through the driving motor, the rotating table 4 is driven to rotate, so that the meals on its top can be displaced, thus facilitating the picking up of the meals. When the table body 1 needs to be expanded, the clamping block 31 is pressed to displace it out of the internal position of the limiting gear 30, so that the limiting gear 30 can rotate, and thus the limiting rod 28, the third gear 29, the second gear 25, the connecting rod 24 and the first gear 23 rotate. Therefore, the guide rod 21 can be displaced to guide the expansion plate 3. The moving block 14 is displaced by the compression spring 15, so that the rotating rod 13 can be displaced, driving the expansion plate 3 to be displaced. With the cooperation of the sliding block 18 and the sliding groove 19, the expansion plate 3 can be expanded. When the expansion plate 3 needs to be stored, the expansion plate 3 is displaced, and the sliding block 18 is displaced to the inner side of the sliding groove 19, so that the guide rod 21 can be reset. The clamping rod 32 can be limited by the torsion spring, so that the clamping rod 32 can limit the clamping block 31 in a connecting manner, and the clamping block 31 is limited inside the limiting gear 30, so that the limiting gear 30 can limit the limiting rod 28. The third gear 29 is limited by the limiting rod 28, so that the third gear 29 can limit the second gear 25, and thus the connecting rod 24 can be limited to limit the first gear 23. With the cooperation of the meshing groove 22 to limit the guide rod 21, the expansion plate 3 can be limited and stored inside the support table 2 to prevent the expansion plate 3 from shifting and affecting the use of the table body 1. Compared with the existing telescopic table, the present invention can improve the overall practicability of the telescopic table through the design.

[0040] The above embodiments are the preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of this technical solution is within the protection scope of the present invention.
