Specific implementation mode
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, below in conjunction with the accompanying drawings and specific real
Applying mode, the present invention is described in further detail.
Fig. 1 show one embodiment of the invention push-pull rod component be installed in car body frame side view.Fig. 2 is shown
Push-pull rod component is installed in the front view of the frame of car body.
Car body includes front baffle and afterframe.Fig. 1 and frame shown in Fig. 2 120 can be car body front baffle or
Afterframe.It is " preceding " and " rear " respectively for car body direction of advance, it is not specially limited.When the push-pull rod group of the present invention
When part is installed in front baffle, which can for example be advanced by pulling；It, should when the push-pull rod component is installed in afterframe
Pushing and pulling vehicle can for example be advanced by pushing.
In conjunction with shown in Fig. 1, which includes U-frame 122 and the cross bar 121 through the U-shaped bottom frame 122 opening.
Push-pull rod component 110 includes fixed linkage 111, sliding linkage 112, the mechanical lock on sliding linkage
113 and the buffer spring mechanism 114 mounted in fixed 111 lower end of linkage.The push-pull rod component 110 is by being arranged in cross bar
Buckle 121a on 121 and the buffer spring mechanism 114 being arranged in the lower central of U-frame 122 are maintained on frame 120.
Fig. 3 and Fig. 4 show one embodiment of the invention push-pull rod component be installed in car body frame perspective view, and
Enlarged diagram at A, the buffering spring component 114 proposed for illustrating the embodiment of the present invention.
As shown in Figure 3 and Figure 4, buffer spring mechanism 114 include the first swivel 114a, the second swivel 114b and
Holddown spring 114c.First swivel 114a is fixedly connected on fixed linkage 111, and the second swivel 114b is fixedly connected
In the lower part of U-frame 122, such as can be fixedly connected by adapter 122a that is fixed or being integrally formed on U-frame 122
In the lower part of U-frame 122.Holddown spring 114c is for compressing the first swivel 114a and the second swivel 114b, when the
When one swivel 114a is relative to the second swivel 114b rotations, the elastic force that holddown spring 114c applies becomes larger so that the
One swivel 114a needs the resistance overcome to become larger in rotation, until can not be further continued for overturning.Therefore, buffer spring mechanism
114 can be such that push-pull rod component 110 does not fall out on the ground, to protect the part on push-pull rod component 110 not damage.Simultaneously
The cleaning for also facilitating push-pull rod component 110, eliminate leads to user repeatedly because needing again to reset push-pull rod component 110
The trouble bent over.
If not having the buffer spring mechanism of lower section, when the buckle 121a on push-pull rod component 110 and cross bar 121 is detached from
It later,, may be around due to the dead weight of push-pull rod component 110 after user mistakenly releases push-pull rod component 110
The structure that lower section is connect with U-frame is fallen.Since the dead weight of push-pull rod component 110 is larger, the part on push-pull rod component 110 can
It can damage, eliminate the burden picked up again after falling.
In state shown in Fig. 1, push-pull rod component 110 is detached from from the buckle 121a on cross bar 121, shown in Fig. 2
In state, push-pull rod component 110 is fixed on the buckle 121a of cross bar 121.In the state of Fig. 2, the cunning of push-pull rod component 110
Lever mechanism 112 is connected in buckle 121a.That is outsides of the buckle 121a for the inside dimension and sliding linkage 112 of fixing
Size fit so that buckle 121a can fix sliding linkage 112, and can allow user that will slide linkage 112 from card
It is detached from button 121a.
The push-pull rod component 110 is scalable and is automatically locked, to adapt to requirement of the vehicle operating status to handle length.When
When vehicle is in running order, the length of push-pull rod component 110 is for example long at 80 to 90 centimeters, when vehicle is in folded state,
The length of push-pull rod component 110 is for example at 50 to 60 centimeters.The elongation and shortening of push-pull rod component 110 are by fixed linkage
111, fixed bar assembly 112 and mechanical lock 113 are realized.Fixed linkage 111 forms accommodating space 111a, slides linkage
112 can slide in the accommodating space 111a that fixed linkage 111 is formed, sliding linkage 112 and 111 weight of fixed linkage
The length of the part of conjunction more short then push-pull rod component 110 is longer.It is extended relative to fixed linkage 111 in sliding linkage 112
Extreme position when, this position can be locked using mechanical lock 113.Mechanical lock 113 is, for example, semi automatic machine lock, tool
It is, for example, upper fixing element, the second fixing piece 113b to have the first fixing piece 113a and the second fixing piece 113b, the first fixing piece 113a
For example, descend fixing piece.First fixing piece 113a is arranged on the top of fixed linkage 111, and the second fixing piece 113b is arranged in cunning
The bottom end of lever mechanism 112 is provided on first fixing piece 113a on lock 1131a, the second fixing piece 113b and is provided with lock tongue
1131b latches 1131a and lock tongue 1131b cooperations, is locked when push-pull rod component 110 is in stretch position.
The present invention also proposes a kind of push-and-pull vehicle, including above-mentioned push-pull rod component 110 and frame 120.Fig. 5 is the present invention one
The perspective view of the push-and-pull vehicle of embodiment, is shown front baffle 20 and afterframe 30, the push-pull rod component (Fig. 5 is not shown)
Can be installed on front baffle 20 or afterframe 30, i.e., the frame 120 in Fig. 1 to Fig. 4 can be Fig. 5 in front baffle 20 or after
Frame 30, does not repeat herein.
It can be seen from the above, a kind of push-pull rod component of proposition of the embodiment of the present invention and push-and-pull vehicle, the buffering elastic of push-pull rod component
Spring mechanism can be such that push-pull rod component does not fall out on the ground, to protect the part on push-pull rod component not damage.Simultaneously also
The cleaning for facilitating push-pull rod component is eliminated because needing push-pull rod component resetting the fiber crops for causing user to bend over repeatedly again
It is tired.
Push-pull rod component to the present invention and push-and-pull vehicle above, are described in detail, specific case used herein
Principle and implementation of the present invention are described, and the explanation of above example is only intended to help to understand original of the invention
Reason and core concept；Meanwhile for those of ordinary skill in the art, according to the thought of the present invention, in specific implementation mode and
There will be changes in application range, in conclusion the content of the present specification should not be construed as limiting the invention.
