Example 1

A linkage lifting structure of a disk in the middle of a desk is mainly used for driving the lifting of a central original disk desktop in the middle of the desk. The table comprises a support frame connected to a table frame, and the support frame can be connected with a table body so as to be installed on the table. The support frame comprises a bottom plate 23, two opposite sides of the upper top surface of the bottom plate 23 are respectively provided with a side plate 21, and the side plates 21 are fixedly connected to the bottom plate 23. Install slide rail 22 on the side that is close to another curb plate 21 of every curb plate 21, two slide rails 22 install respectively between two curb plates 21 and connect on the medial surface that corresponds curb plate 21 promptly, every slide rail 22 all can slide along slide rail 22's length direction on corresponding curb plate 21 under the exogenic action, and the slide rail 22 accessible linkage elevation structure that removes drives the disc concatenation desktop and stretches out the table body and with main desktop parallel and level or shrink nearly in the table body. A wedge block 27 is mounted on the slide rail 22, and the wedge block 27 is movable along the length direction of the slide rail 22 together with the slide rail 22. A mounting base 32 is arranged above the bottom plate 23, and a central disc table top 33 can be directly or indirectly mounted on the mounting base 32; the mounting base 32 is suspended above the bottom plate 23, and the mounting base 32 can move in a direction perpendicular to the bottom plate 23 under the action of external force, so that the central disc table top 33 can be lifted. In order to realize the lifting of the installation base 32, lateral connecting plates 29 are fixedly connected to the two sides of the installation base 32 at positions corresponding to the side plates 21, and the inclined surfaces of the lateral connecting plates 29 abut against the wedge blocks 27. When the wedge 27 moves along the slide rail 22, the moving wedge 27 will drive the lateral connection plate 29 to move up and down (i.e. move in a direction perpendicular to the bottom plate 23) due to the overlapping effect of the wedge 27 and the inclined surface of the lateral connection plate 29.

The lower portion of the disk mounting assembly 31 is located within the recessed mounting region 36.

In addition, in order to effectively control the slide rail to drive the wedge block 27 to move, the mounting base 32 can only lift up and down, and prevent the mounting base 32 from moving along with the wedge block 27, therefore, the guide post guide sleeve 30 can be arranged at the bottom of the mounting base 32, a guide through hole is arranged on the side plate 21 corresponding to the guide post guide sleeve 30, and the guide post guide sleeve 30 passes through the guide through hole and can move along the axial direction of the guide post guide sleeve 30. Under the action of the guide post guide sleeve 30 and the guide through hole, the movable wedge block 27 can enable the mounting base 32 to move along the axial direction of the guide post guide sleeve 30, and lifting of the mounting base 32 and the central disc tabletop 33 is achieved.

The working principle is as follows: when the lifting platform is used, the motor drives the driving gear 25 to rotate, so that the disc gear 24 is driven to rotate, the two driving rods 11 simultaneously extend outwards, the two sliding frames 20 are forced to be pushed outwards, in the process, the driving rods 11 rotate around the sliding frames 20, when the driving rods 11 are to be extended to the maximum position, the driving columns 10 act on the guide plates 3, the driving rods 11 drive the guide plates 3 to transversely move until the driven columns 8 pass through inclined holes of the driven rod guide holes 4, the driven rod guide holes 4 limit the linear displacement of the driven columns 8, so that the driven rods 7 are driven to slide on the base 12, the driven rods 7 slide to drive the supporting rods 15 to move, so that the connecting rods 14 are supported, the upper ends of the connecting rods 14 rotatably ascend, so that the lifting platform 13 is driven to ascend to the preset position, the driving rods 11 continue to rotate for a certain angle after extending to the longest distance, and the driving rods 11 drive the sliding frames 20 to inwards approach to be attached to the main table plate on the supporting frame to complete deformation, in the process, the driven column 8 is arranged at the lower end of the driven rod guide hole 4 and does not move linearly, so that the height of the lifting platform 13 is kept unchanged; when the sliding frame needs to be retracted, the disc gear 24 rotates reversely, the driving rod 11 drives the two sliding plates to move outwards at the same time, after the driving rod 11 bypasses an angle perpendicular to the sliding frame 20, the guide plate 3 is stressed to translate, the driven plate is driven to slide reversely on the base 12, the supporting rod is driven to move, the connecting rod 14 rotates and descends, the lifting platform 13 descends until the lifting platform is kept unchanged, the driving rod 11 continues to rotate along with the disc gear 24, the sliding frame 20 is stressed to contract inwards synchronously, and the two sliding frames are driven to retract to a preset position.
