Utility model content
The purpose of this utility model is to provide a kind of buffer spring of multiple spring relays.
What the purpose of this utility model was realized in：A kind of buffer spring, it is characterised in that：Including arranged on exterior the
One spring and middle second spring and the 3rd internal spring, further include the resilient sleeve for wrapping up each spring, further include and be arranged on
The first exterior cup dolly, further includes arranged on the second middle cup dolly, further includes arranged on inner most 3rd circular base
Seat, further includes and is arranged at the supercentral center-pole of each cup dolly, further include and be arranged at the first cup dolly center of lower end
Guide rod, first cup dolly and the first spring are closely coupled, and second cup dolly and second spring are closely coupled, institute
State the 3rd cup dolly and the 3rd spring is closely coupled, the center-pole tip portion is guide sleeve.
Compared with prior art, the beneficial effects of the utility model are：Since second spring and the 3rd spring be not with
Base is directly connected to, and the power of application is buffered and diminished in the form of relay；Since the top of center-pole and guide rod is provided with rubber
Pad, power is able to be disperseed to absorb when collision；Due to being provided with guide sleeve and the component of guide rod form, bullet in the inside of spring
Spring will not be distorted the phenomenon of deformation and disalignment during compression.
As the preferred solution of the utility model, the second spring is arranged on the first spring inner, and the 3rd spring is set
Inside second spring.
As the further preferred scheme of the utility model, the second spring and the 3rd spring upper end are justified with second respectively
Shape base and the 3rd cup dolly are closely coupled, while are not connected with being arranged on the first cup dolly of the first lower spring end.
As the further preferred scheme of the utility model, it is straight that the second cup dolly diameter is less than the first cup dolly
Footpath is simultaneously disposed below, and the 3rd cup dolly diameter is less than the second cup dolly diameter and is disposed below, described first
Spring, second spring, the 3rd spring and the first cup dolly, the second cup dolly, the 3rd cup dolly are on the same axis simultaneously
It is arranged in order.
As the further preferred scheme of the utility model, the center-pole tip portion is guide sleeve form, the guide rod
Stretch into guide sleeve, the guide rod and guide sleeve simultaneously can mutually be slidably matched in same axis.
As the further preferred scheme of the utility model, the guide sleeve bottom and guide rod top are all provided with rubber pad.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Wherein, 1 first spring, 2 second springs, 3 the 3rd springs, 4 first cup dollies, 5 second cup dollies, 6 the 3rd
Cup dolly, 7 center-poles, 8 rubber pads, 9 resilient sleeves, 10 guide sleeves, 11 guide rods.
Embodiment
As shown in Figure 1, a kind of buffer spring, including arranged on the first exterior spring 1 and middle second spring 2 and inside
The 3rd spring 3, further include the resilient sleeve 9 for wrapping up each spring, further include arranged on the first exterior cup dolly 4, further include
Arranged on the second middle cup dolly 5, further include arranged on inner most 3rd cup dolly 6, further include and be arranged at each circular base
The supercentral center-pole 7 of seat, further includes the guide rod 11 being arranged at 4 center of the first cup dolly of lower end, first circular base
Seat 4 is connected with the first spring close 1, and second cup dolly 5 and second spring 2 are closely coupled, the 3rd cup dolly 6
Closely coupled with the 3rd spring 3,7 tip portion of center-pole is guide sleeve 10.
Above-mentioned second spring 2 is arranged on inside the first spring 1, and the 3rd spring 3 is arranged on inside second spring 2.
Above-mentioned second spring 2 and 3 upper end of the 3rd spring respectively with 6 close phase of the second cup dolly 5 and the 3rd cup dolly
Even, while it is not connected with being arranged on the first cup dolly 4 of 1 lower end of the first spring.
Above-mentioned second cup dolly, 5 diameter is less than 4 diameter of the first cup dolly and is disposed below, the 3rd cup dolly 6
Diameter is less than 5 diameter of the second cup dolly and is disposed below, and the first spring 1, second spring 2, the 3rd spring 3 and first are circular
Base 4, the second cup dolly 5, the 3rd cup dolly 6 on the same axis and are arranged in order.
Above-mentioned 7 tip portion of center-pole is guide sleeve 10, and the guide rod 11 is stretched into guide sleeve 10, and guide rod 11 and guide sleeve 10 are same
One axis simultaneously can mutually be slidably matched.
Above-mentioned 10 bottom of guide sleeve and 11 top of guide rod are all provided with rubber pad 8.
The operation principle of the utility model is described below, and when receiving power application, the first spring 1 is compressed, when first
When spring pressure 1 is reduced to certain distance, second spring 2 touches the first cup dolly of lower end 4, and at the same time second spring 2 starts
Compression, while after compressing a distance, the 3rd spring 3 touches the first cup dolly of lower end 4, and is compressed, last guide rod
11 with guide sleeve 10 slide relatively, collide between the rubber pad 8 of 10 bottom of rubber pad 8 and guide sleeve on 11 top of guide rod,
