Specific implementation mode:
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
As shown in Figs. 1-3, the utility model one kind does not fall terraced balancing device, including the left ladder 1 that upper end is hinged
With right ladder 2, left connecting rod 3, right connecting rod 4, supporting rod 5 and balancing trolley 6, the balancing trolley 6 is located at left ladder 1 and right ladder
Middle part between frame 2, balancing trolley 6 constitute sliding pair with ground；The supporting rod 5 includes that diameter is sequentially increased from top to bottom
One body of rod 501 and second body of rod 502, second body of rod, 502 lower end and the middle part of balancing trolley 6 connect firmly, first body of rod
Sliding sleeve is equipped with a sliding block 7 on 501, sliding block 7 and first body of rod 501 composition sliding pair, the sliding block 7 and second body of rod 502
The adjustable spring 8 in first body of rod of socket, 501 outside is equipped between top surface can be reduced in motion process by the way that adjustable spring 8 is arranged
Impact force, improve the stressing conditions of integrated model；The top of first body of rod 501 is additionally provided with to limit sliding block 7
The locating part of position；The left connecting rod 3 and right connecting rod 4 are located at homonymy, the outboard end of left connecting rod 3 and right connecting rod 4 respectively with left ladder 1
It is hinged with right ladder 2, left connecting rod 3 and the inner end of right connecting rod 4 are hinged with sliding block 7.
In the present embodiment, the balancing trolley 6 includes vehicle frame 601, and the left and right both ends of the vehicle frame 601 are equipped with respectively
The front and rear ends of one longitudinally disposed support shaft, the support shaft are connected separately with wheel 602.
In the present embodiment, the lower end and the middle part of vehicle frame 601 of second body of rod 502 connect firmly.
In the present embodiment, the sliding block 7 is fixed with a longitudinally disposed articulated shaft close to left connecting rod 3 and 4 side of right connecting rod
701, the articulated shaft 701 is hinged with the inner end of left connecting rod 3 and the inner end of right connecting rod 4.
In the present embodiment, the upper end outer wall of first body of rod 501 is provided with external screw thread；The locating part is stop nut
9, the stop nut 9 is matched with the external screw thread, is convenient to mount and dismount.By the way that locating part is arranged, the mobile model of sliding block can be limited
It encloses, to limit the included angle between left connecting rod 3 and right connecting rod 4, ensures that the included angle of ladder is consistently greater than 20 degree, make ladder
Son will not topple over, and ensure the safety of user.
Specific implementation process：As shown in figure 4, initial time, user gives the impact force of left ladder 1 one to the left, makes a left side
Ladder 1 is rotated counterclockwise around the supporting point o of itself and bottom surface, and right ladder is driven to be moved downward with 2 left connecting rods 3.Further, Zuo Lian
Bar 3 is rotated clockwise around the revolute pair of itself and left ladder 1, and right connecting rod 4 is rotated counterclockwise around the revolute pair of itself and right ladder 2,
With under effect while right connecting rod 4, band movable slider 7 moves down left connecting rod 3 along first body of rod 501.Further, sliding block 7
Adjustable spring 8 is compressed, left ladder 1 and the angle of right ladder 2 taper at this time, the top surface of adjustable spring 8 and second body of rod 502
Moving down for sliding block 7 is limited jointly, ensures that the left ladder 1 of this process and the minimum value of the angle of right ladder 2 are more than 20 degree.With
Sliding block 7 to continue to move down, the elastic force of adjustable spring 8 gradually increases, when its elastic force numerical value and impact force reach balance, left ladder
Closed action is completed in the 6 equal stop motion of 1 frame, right ladder 2 and balancing trolley, and the angle of ladder is by 30 degree of original changes at this time
At 20 degree.
Further, user gradually moves to right its center of gravity, at this time right ladder 2 by ground support force and stiction
More than left ladder 1, when the stiction that left ladder 1 is subject to is sufficiently small, the adjustable spring 8 that compresses at this time push sliding block 7 along
First body of rod 501 moves up, and pushes left ladder 1 to move downward by left connecting rod 3, completes expansion action.The folder of ladder at this time
Angle becomes 30 degree by 20 degree, from fig. 4, it can be seen that ladder has moved downward a distance, specially OO ', completes a fortune
The dynamic period.
The above is only the preferred embodiment of the present invention, it is all done according to present utility model application the scope of the claims it is equal
Deng variation and modification, it should all belong to the covering scope of the utility model.
