Application method and principle: being gone downstairs using perambulator of the present invention, as shown in figure 4, retaining pin A 510 is not before going downstairs
Dynamic, i.e. pin A 510 is applied on outer cylinder 501, and extracting pin B 511 restores spring C 506 automatically by compressive state to natural shape
State, while pushing telescopic rod 502 to extend by the reseting elasticity of spring C 506, i.e., the flexible formula shake device 5 that subtracts extends, flexible to subtract formula
It shakes device 5 and extends rear support at lower halfpace, and then play real-time supporting role, avoid car body 1 vacantly, push baby
Under vehicle when halfpace, perambulator is absorbed in the impact force that vertical direction generates by spring C 506, plays the work of buffering and damping
With so that process of going downstairs is very steady, safe and reliable；It is gone upstairs using perambulator of the present invention, as shown in figure 5, before going downstairs
Pin A 510 and pin B 511 is extracted, restores spring B 505 to nature automatically by elongation state, while by spring B 505
Reseting elasticity pull telescopic rod 502 shrink, and due to the elongation of spring B 505 be less than spring C 506 decrement, make
It obtains telescopic rod 502 to shorten, i.e., the flexible formula shake device 5 that subtracts shortens, and stretching to subtract after formula shake device 5 shortens conveniently is supported on higher ladder
At platform, so convenient upper halfpace, while real-time supporting role is played, when pushing halfpace on perambulator, perambulator is in vertical direction
The impact force of generation is absorbed by spring B 505 and spring C 506, plays the role of buffering and damping, so that process of going upstairs
It is very steady, safe and reliable；It is walked on level road using perambulator of the present invention, as shown in Figure 1, when pin A 510 and pin B 511 is same
When being applied on outer cylinder 501, spring B 505 and spring C 506 are limited at inactive state, are unable to free extension, i.e.,
The flexible formula shake device 5 that subtracts is in stationary state；When pin A 510 is applied on outer cylinder 501, B 511 is sold in extraction, then spring C 506
Restored automatically by compressive state to nature, so that the flexible formula shake device 5 that subtracts is in flexible state, spring C 506 can be passed through
Buffering and damping, this process, which should be noted that, should slightly appear on the stage at 1 rear portion of car body in order to which perambulator holding level moves ahead.
In use process, the mutual cooperation of fastener and spring A 504 can either play the role of limit, and not influence telescopic rod 502
It is flexible, while telescopic rod 502 can be prevented excessively flexible.When restoring pin A 510 and pin B 511, it is only necessary to push car body, i.e.,
Pin A 510 and pin B 511 can be penetrated corresponding position.Further, it is also possible to gone upstairs by hauling perambulator, during this, stretch
Reduction formula shakes device 5 under the effect of elasticity in elongation and the cycle alternation state shortened.
