[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0023] Please refer to Figure 1-6 , the present utility model provides a technical solution: a telescopic and expandable conference table, including a base 1, a support frame 2 is fixedly connected to the upper end of the base 1, sliding grooves 4 are opened on the upper end surfaces of both sides of the support frame 2, a tabletop 3 is slidably connected to the upper end of the support frame 2, the tabletops 3 are symmetrically arranged, a bidirectional driving mechanism is arranged in the sliding groove 4, the bidirectional driving mechanism includes a rack 6, the end of the rack 6 is fixedly connected to the lower end of the tabletop 3, a gear 5 is rotatably connected to the middle position of the sliding groove 4, the gear 5 is meshed with the rack 6, the racks 6 at the lower ends of the two tabletops 3 are arranged in a staggered manner, an expansion mechanism is arranged in the base 1, the expansion mechanism is matched with the support frame 2 and is also matched with the tabletop 3; adjust the distance between the tabletops 3 according to the number of people in the meeting. When there are many people in the meeting, pull the tabletops 3 to both sides. When pulling, drive the rack 6 to move outward. When the rack 6 moves outward, drive the gear 5 to rotate. The gear 5 drives the inner staggered rack 6 to move outward. Thus, the two end tabletops 3 can move outward simultaneously, and the moving distances are symmetrically equal. Then take out the expansion mechanism and place it on the support frame 2, and then push the tabletops 3 inward to clamp the expansion mechanism. Push the tabletops 3 to lift the expansion mechanism and increase the distance between the tabletops 3, thereby increasing the overall length.
[0024] As Figure 4 shown, the expansion mechanism includes: expansion plates 11, the expansion plates 11 are symmetrically arranged, and the lower end portions of the expansion plates 11 are hinged, a limiting plate 12 is fixedly connected to the lower end of the expansion plate 11, the limiting plate 12 is arranged outside the support frame 2, the two expansion plates 11 are connected by a hinge. After the expansion plates 11 are rotated and unfolded, the limiting plate 12 is buckled downward outside the support frame 2, and the expansion plates 11 can be fixed by the clamping and pushing of the tabletop 3.
[0025] As Figure 2 and Figure 6 shown, a guiding groove 8 is opened in the middle of the base 1, a guiding plate 9 is fixedly connected to the lower end of the tabletop 3, the guiding plate 9 is slidably arranged in the guiding groove 8, and the guiding groove 8 is arranged in an inverted T shape. The guiding plate 9 at the lower end of the tabletop 3 slides in the guiding groove, and the limitation of the guiding groove 8 and the guiding plate 9 can make the tabletop 3 move outward more stably and avoid the loosening of the tabletop 3.
[0026] As Figure 3 andFigure 4 As shown, a plug block 14 is fixedly connected to the side of one table board 3, and a slot 13 is formed in the side of the other table board 3. The slot 13 is arranged to be in mating plug connection with the plug block 14. A slot 13 is also formed in one side of the extension board 11, and a plug block 14 is fixedly connected to the other side. When the table board 3 abuts against the extension board 11, the slot 13 and the plug block 14 are plugged together to achieve a stable connection between the extension board 11 and the table board 3. Moreover, when the two table boards 3 are combined, they can also be plugged together through the slot 13 and the plug block 14 to achieve a stable connection effect.
[0027] As Figure 5 shown, placing frames 10 are fixedly connected to both inner ends of the base 1, and the extension board 11 is placed in the placing frames 10. The placing frames 10 are arranged as strip-shaped frames. After the extension board 11 is folded, it is placed into the frames, so that there is space to take out the extension board 11 when taking the extension board 11, which is convenient for the operator to operate.
[0028] As Figure 2 shown, a stop block 7 is fixedly connected to the end of the rack 6. By the limitation of the stop block 7, the table board 3 is prevented from being pulled outwards too much, and the rack 6 is prevented from being disengaged from the gear 5, thereby making the movement of the table board 3 more stable and firm.
[0029] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to make equivalent embodiments with equivalent changes within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
