One end and realize flexible folding and unfolding.It should be appreciated that turn to bending when tensioning occurs for flexible element, such as walked by being horizontally orientated to switch to vertical
Xiang Shi, bending place are correspondingly arranged the drive being anchored on straight-arm 0110, ensure the stabilization of flexible driving.
Wherein, flexible driving relation, it is a kind of common machine driving, generally by two or more drives 0133 with scratching
Property part 0140 form, motion and power are transmitted between drive 0133 by flexible element 0140.According to the class of flexible element 0140
Type, flexible driving mainly have V belt translation, Chain conveyer and rope drive, drive 0133 respectively belt wheel, sprocket wheel and rope sheave, flexible element
0140 is respectively transmission belt, driving-chain and transmission rope.Wherein, the first fixed wheel 0131, the second fixed wheel 0132 belong to driving wheel 0133
In drive 0133.In an exemplary embodiment, flexible element 0140 is steel wire rope, has preferable structural strength.
Wherein, the directional spreding that the first fixed wheel 0131 and the second fixed wheel 0132 move along a straight line is on motion 0120.
In other words, the first fixed wheel 0131 is parallel with the direction to move along a straight line with the mandrel line of the second fixed wheel 0132.Meanwhile first fixed wheel
0131 and second fixed wheel 0132 be respectively provided with rotation ability.In an exemplary embodiment, the first fixed wheel 0131 and second is fixed
The equal keep level in axial direction of wheel 0132, and do not relatively moved between the first fixed wheel 0131 and the second fixed wheel 0132.
Wherein, driving wheel 0133 is used for the horizontal drag force for connecting weight and receiving user's input.Driving wheel 0133 is only by scratching
Property part 0140 and be connected respectively with the first fixed wheel 0131, the second fixed wheel 0132, in driving wheel 0133 and/or the Gravitative Loads of weight
Under, flexible element 0140 keeps being tensioned and being pressed in the upper surface of the first fixed wheel 0131 and the second fixed wheel 0132 naturally.In flexibility
During the folding and unfolding of part 0140, relative position of the driving wheel 0133 respectively with the first fixed wheel 0131, the second fixed wheel 0132 changes,
The vertical of driving wheel 0133 is lifted, realizes the lifting and decline of driving wheel 0133 and weight.In an exemplary embodiment, driving wheel
0133 is connected with hook 0160, for hanging up weight.
It should be appreciated that the flexible element between the first fixed wheel 0131 and driving wheel 0133, the fixed wheel 0132 of driving wheel 0133 and second
0140 keeps vertical tensioning.Flexible element 0140 is tensioned to the first fixed wheel 0131 close to the side of the second fixed wheel 0132, the second fixed wheel
