Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1~4 schematically show a kind of chair leg angle adjustment machine of embodiment according to the present utility model
Structure.
As depicted in figs. 1 and 2, the chair leg angle-adjusting mechanism, including fixed frame 1, shrinking connecting-rod holder 2, leg
Support plate 3 and driving mechanism 4.One end of shrinking connecting-rod holder 2 is fixedly connected with thigh support board 3, shrinking connecting-rod holder 2 it is another
One end is provided with power rail 21 and hinge bar 22.Power rail 21 is connected with fixed frame 1, and hinge bar 22 is cut with scissors with 1 phase of fixed frame
It connects, driving mechanism 4 is matched with power rail 21.
In the present embodiment, shrinking connecting-rod holder 2 is two, is set up separately in the both sides of fixed frame 1.Shrinking connecting-rod holder 2 is more
Grade connecting rod.Shrinking connecting-rod holder 2 is hingedly formed by plurality of rods, wherein including just power rail 21 and hinge bar 22.
The chair leg angle-adjusting mechanism of present embodiment further includes guide rod 5, and fixed frame 1 is provided with the first guide groove
11, power rail 21 is provided with the second guide groove 23, and guide rod 5 passes through the first guide groove 11 and the second guide groove 23, power rail 21
End and fixed frame 1 it is hinged.The both ends of guide rod 5 are corresponding with two shrinking connecting-rod holders 2 respectively.
When shrinking connecting-rod holder 2 is driven, guide rod 5 moves in the first guide groove 11 and the second guide groove 23, and two lead
Guide and limit effect has been moved to guide rod 5 to slot, and then restriction effect is risen to the stretching motion of shrinking connecting-rod holder 2.
