Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, and for explaining only the invention, and is not considered as limiting the invention.
As shown in Figure 1 to Figure 2, a kind of full buffer low-angle that the present invention describes stretches buffer, including cylinder shell 1 and piston
Bar 12, the opening of cylinder shell 1 are sequentially installed with plastics front cover 11, third sealing ring 10 and plastic spacer 9, wherein third sealing
Y-type seal ring can be used in circle 10, and the top jag position of the y-type seal ring presses plastic spacer 9, when plastic spacer 9 is pressurized
When, y-type seal ring is applied with better buffer function power to plastic spacer 9.12 one end of piston rod sequentially pass through plastics front cover 11,
It third sealing ring 10 and plastic spacer 9 and extends in cylinder shell 1,12 one end piston rod head 1201 of piston rod, piston rod head
1201 are equipped with meson 6 and piston 8, and return piston 3 is equipped in middle cylinder shell 1, and return piston 3 can separate in 1 inner cavity of cylinder shell
Vacuum chamber 13 and damping cavity 5 out are placed with damping oil in damping cavity 5, are equipped with reset spring 2, reset spring 2 one in vacuum chamber 13
End peaks on return piston 3, and 2 other end of reset spring peaks on 1 inner cavity of cylinder shell.
This structure is combined by reset spring 2 and return piston 3, can be implemented in compression a small range using reset spring 2
Small range buffering effect；Cooperate piston 8 in 13 switching position of damping cavity, enables damping oil to implement to buffer on a large scale to piston 8, most
Make small range and a wide range of combination buffering method eventually, can implement to be compressed to any position and stretch have buffering effect, solve previous
It can not full buffer disadvantage.
As shown in Figure 1, in the full state that pulls out: piston rod head 1201 is equipped with meson 6 and piston 8, and the drawing of piston rod 12 is arrived
To right end, piston 8 is peaked on plastic spacer 9, is placed with damping oil in damping cavity 5, which, which is located at meson 6 and resets, lives
Between plug 3；At this point, return piston 3 is located at the middle position in cylinder shell 1, reset spring 2 is in open configuration, and limits
3 position of return piston processed, vacuum chamber 13 are in vacuum state.
As shown in Fig. 2, being in compressive state and having buffering effect: piston rod 12 is shifted to right end, 8 squeezed air-damping chamber of piston
Damping oil in 5, damping oil buffer piston 8, and damping oil, in extrusion process, damping oil enters the right side of damping cavity 5
At side, piston 8 will continue to mobile and be in contact with return piston 3, and piston 8 and return piston 3 shift at right end together, reset
Spring 2 is squeezed, and is squeezed at this time using reset spring 2 and is implemented low-angle buffering effect, the low-angle buffering course
It the technical problems such as can not buffer to solve to be in one section of small distance between door body and furniture.
When door body little Xu is opened, it is in one section of small distance position, which pushes return piston 3 to right end
Displacement drives piston rod 12 to be moved at right end, at this point, piston rod 12 again right shift when, the damping positioned at the right side of damping cavity 5
Oil comes back to origin-location when being squeezed, and waiting buffers next time, and piston rod 12 is now in full pull-out state.
Wherein damping oil pressure is more than the inner wall pressure of the squeeze cylinder shell 1 of the second sealing ring 7, and damping oil pressure is flowed into from gap
At the left or right side along damping cavity 5.Damping oil when switching position, implements wide-angle buffer effect in damping cavity 5.
Plastics front cover 11, third sealing ring 10 and plastic spacer 9 are fixed on the opening of cylinder shell 1, and implement seal shape
State can stop piston 8 and piston rod 12 to be detached from cylinder shell 1.
As depicted in figs. 1 and 2, the outer surface of return piston 3 of the present invention is equipped with installation groove 401, installation groove 401
First sealing ring 4 is installed, the first sealing ring 4 can be allowed to be fixed in installation groove 401, makes the first sealing ring 4 will not be careless
It is detached from；The outer surface of first sealing ring 4 peaks at 1 internal chamber wall of cylinder shell, implements vacuum effectiveness, avoids damping oil from entering true
In cavity 13, damping oil effect is kept.In addition, 3 surface of institute's rheme piston is equipped with spill arc position 402, piston rod 12, which is in, to be squeezed
Under state, piston rod head 1201 is placed at spill arc position 402, can accommodate piston rod head 1201, further allow return piston 3 and be situated between
Sub 6 phases are close to implement the transmitting of power.The piston 8 is equipped with the second sealing ring 7, and the outer surface of the second sealing ring 7 peaks in cylinder shell 1
At cavity wall, leakage effect is prevented；The reset spring 2 is under squeezed state, outer surface and the 1 inner wall phase of cylinder shell of reset spring 2
It does not collide mutually, plays preferable buffering effect.
Upper is only presently preferred embodiments of the present invention, is not intended to limit the invention, all in spirit and original of the invention
Made any modification, equivalent replacement or improvement etc., should all be included in the protection scope of the present invention within then.
