The hollow parts inside the first lifting rod 311, the third lifting rod 313 and the second lifting rod 312 are communicated to form a threading channel. The wire 900 may be threaded from the mounting plate 600 through the threading channel to the circular hole of the turntable assembly 200 and clamped by the wire clamp 220 to provide power to the item 800 displayed on the hollow turntable 210. Thus, after the middle idle rotary disc 210 rotates, the wires 900 cannot be wound, the wiring is convenient, and the power consumption requirement of the articles 800 on the hollow rotary disc 210 can be met.
The lifting and rotating platform 10 provided in the present embodiment works as follows:
when the driving member 100 is actuated and the locking member is in the first state, the second lifting rod 312 is fixedly connected to the turntable assembly 200, so that the rotation of the turntable assembly 200 is limited, i.e., the rotation of the second lifting rod 312 is limited. The second lift lever 312 cannot rotate but moves only in the axial direction of the third lift lever 313. When the third sleeve holder 433 abuts against the second stopper 442, the movement of the second lifting rod 312 is also limited, and the second lifting rod 312 cannot move nor rotate. At this time, the rotation of the third lifting rod 313 is limited, the rotation resistance of the third lifting rod 313 is greater than the force of the screw-fit of the third lifting rod 313 and the first lifting rod 311, the third lifting rod 313 and the first lifting rod 311 start to rotate relatively, the third lifting rod 313 moves along the axial direction of the first lifting rod 311 until the second sleeve fixing seat 432 abuts against the first stopper 441, and at this time, the third lifting rod 313 cannot rotate nor move. The lifting assembly 300 completes the lifting. At this time, the locking member is switched to the second state, the rotation of the turntable assembly 200 is no longer limited, and the power of the driving member 100 is transmitted through the first lifting rod 311, the third lifting rod 313 and the second lifting rod 312 to drive the turntable assembly 200 to rotate. In other words, when the driving member 100 is actuated, if the locking member is in the first state, the lifting assembly 300 is lifted, and the turntable assembly 200 is not rotated. When the driving member 100 is actuated, if the locking member is in the second state, the lifting assembly 300 is not lifted, and the turntable assembly 200 rotates.
It should be noted that the locking member may be switched without lifting the lifting assembly 300 to the limit position, or when the lifting assembly 300 reaches a predetermined height, that is, the locking member may be switched, and at this time, the first lifting rod 311, the third lifting rod 313 and the second lifting rod 312 are connected into a whole by screw threads, which may be regarded as a single screw transmission, so as to start the rotation of the turntable assembly 200.
In this embodiment, the locking member includes a retractable guide 420 and a locking pin 410 engaged with the guide 420, and the locking pin 410 can limit the rotation of the turntable assembly 200. When the driving member 100 drives the first lifting rod 311 to rotate, if the locking member is in the first state, the guide member 420 extends and contracts, and the locking pin 410 moves up and down along with the turntable assembly 200. In an alternative embodiment, the locking member includes a guide 420 and a locking pin 410 slidably engaged with the guide 420, the guide 420 being fixed relative to the ground. The locking pin 410 can move in the ascending and descending direction of the turntable assembly 200, and the rotation of the locking pin 410 in the circumferential direction of the turntable assembly 200 is restricted by the guide 420. For example, a large sleeve is sleeved on the outer circumference of the lifting assembly 300, and the plurality of lifting rods 310 are covered in the large sleeve. The locking pin 410 is slidably connected to the large sleeve in a direction parallel to the lifting direction of the lifting rod 310. The second lifting rod 312 is provided with a plurality of locking holes, the locking pin 410 is selectively matched with the locking holes to limit the rotation of the second lifting rod 312, and the second lifting rod 312 is fixedly connected or detachably connected with the turntable assembly 200, so that the rotation of the turntable assembly 200 is limited. When the driving member 100 is actuated and the locking member is in the first state, the turntable assembly 200 is lifted by the lifting assembly 300, and the locking pin 410 slides on the large sleeve to maintain the locked state of the turntable assembly 200.
