Referring to fig. 1 to 3, the operating principle of the mechanism for facilitating the lifting backboard assembly of the present embodiment is as follows:
when the backboard of this embodiment needs to move downwards, the telescopic end of the lower part of the electric push rod extends downwards, the first circular shaft 5 is pushed to swing clockwise, the first sliding shaft sleeve 4 moves towards the top end of the first circular shaft 5, the second sliding shaft sleeve 41 pushes the second circular shaft 7 to swing anticlockwise around the hinge point at the top end, and correspondingly, the third sliding shaft sleeve 42 swings along the vertical central circular shaft 8 through the first circular shaft 5 and the second circular shaft 7, so that the backboard frame 101 moves downwards relative to the mounting frame 2 because the third sliding shaft sleeve 42 is fixedly connected with the backboard frame 101. Because the damping spring 9 is sleeved on the outer peripheral surface of the bottom of the vertical central circular shaft 8, in the process that the third sliding shaft sleeve 42 moves downwards along the outer peripheral surface of the vertical central circular shaft 8, the third sliding shaft sleeve 42 gradually abuts against the top of the damping spring 9 and gradually compresses the damping spring 9, so that the third sliding shaft sleeve 42 slowly moves downwards, namely the backboard 1 slowly moves downwards.
When the backboard 1 of the present embodiment moves downwards to a certain position and the backboard 1 needs to move upwards, the retractable end of the lower portion of the electric push rod 3 is retracted inwards, so as to pull the first circular shaft 5 to swing in the counterclockwise direction, the first sliding shaft sleeve 4 slides towards the lower portion of the first circular shaft 5, meanwhile, the second sliding shaft sleeve 41 pushes the second circular shaft 7 to swing in the clockwise direction, and accordingly, the third sliding shaft sleeve 42 moves upwards along the outer periphery of the vertical central circular shaft 8. When the third sliding sleeve 42 is slid to the topmost position of the vertical central circular shaft 8, the backboard 1 is moved to the topmost position.
The above only is the preferred embodiment of the present invention, not so limiting the patent scope of the present invention, all under the concept of the present invention, the equivalent structure transformation made by the contents of the specification and the drawings is utilized, or the direct/indirect application is included in other related technical fields in the patent protection scope of the present invention.
