Description
Technical field
The utility model relates to spring arts, more particularly to a kind of New Buffering spring.
Background technique
Currently, most of buffer springs are the spiral compressed spring of steel, this kind of spring is with using time mistake
Long to will appear restoring force reduction, spring is also easily because corrosion causes its effect to be deteriorated, to influence its using effect；It is many at present
Gas spring is also used as buffer spring, but gas spring in the prior art only has first-level buffer mostly, that is, passes through piston rod
It is realized with the effect that is enclosed in the indoor closed gas of closed chamber, the poor universality of this kind of spring can not be different to pressure
Situation makes different feedbacks.
Summary of the invention
The utility model is directed to the problems of the prior art, provides a kind of New Buffering spring.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals:
A kind of New Buffering spring comprising hollow spring housing, spring housing inside are equipped with buffer gear, buffer
Structure includes the positive stop lug boss of the piston rod through spring housing and the annular along the setting of spring housing inner sidewall, and positive stop lug boss is located at
The middle part of spring housing, piston rod is passed through from the through-hole that positive stop lug boss surrounds and it is tightly connected with positive stop lug boss with by spring
Shell is divided into two closed chambers, and blind hole is arranged at intervals on the side wall of positive stop lug boss, and portable pillar is provided in blind hole, living
Dynamic column and blind hole side wall are tightly connected, and one end and the piston rod of portable pillar fit closely, the other end of portable pillar to blind via bottom
Space in be compressed air.
Preferably, piston rod includes connecting rod and the plunger that is fixed in connecting rod, plunger is located at through hole, connecting rod
It is reached outside spring housing by the bottom of spring housing.
Preferably, the top of spring housing is equipped with attachment base, attachment base with connecting rod with external structure for connecting.
Preferably, through-hole and plunger are truncated cone-shaped, the section radius of the two is gradually increased from top to bottom.
Preferably, portable pillar is arc surface close to one end end of plunger and its surface is equipped with elastic sealing gasket.
The utility model has significant technical effect: provided by the utility model due to using above technical scheme
Buffer spring provides two-stage buffering, gas of the first-level buffer in the spring housing as caused by the movement of piston in upper and lower two side cavities
Volume change provides, and level 2 buffering is supplied by the confined air air lift in portable pillar compression blind hole, and when stress is smaller, level 2 buffering is made
With the intracorporal two chambers up and down of spring case are connected state at this time, and when stress is larger, portable pillar is pressed into blind hole, spring
Two chambers are closed up and down for shell, and first-level buffer acts at this time.
Detailed description of the invention
Fig. 1-Fig. 3 is the structural schematic diagram under the different compressive states of the utility model.
The toponym that each number designation is referred in attached drawing is as follows: 1-spring housing, 21-connecting rods, 22-plungers,
3-positive stop lug boss, 31-blind holes, 4-portable pillars, 5-attachment bases.
Specific embodiment
The utility model is described in further detail with embodiment with reference to the accompanying drawing.
Embodiment
A kind of New Buffering spring, as shown in Fig. 1-Fig. 3 comprising hollow spring housing 1 is set inside spring housing 1
There is buffer gear, buffer gear includes the limit of the piston rod through spring housing 1 and the annular along the setting of 1 inner sidewall of spring housing
Position boss 3, positive stop lug boss 3 are located at the middle part of spring housing 1, piston rod passed through from the through-hole that positive stop lug boss 3 surrounds and its with
Positive stop lug boss 3 is tightly connected so that spring housing 1 is divided into two closed chambers, is spaced setting on the side wall of positive stop lug boss 3
There is blind hole 31, portable pillar 4 is provided in blind hole 31, portable pillar 4 and 31 side wall of blind hole are tightly connected, one end of portable pillar 4 and work
Stopper rod fits closely, and is compressed air in the other end to the space of 31 bottom of blind hole of portable pillar 4.
Piston rod includes connecting rod 21 and the plunger 22 that is fixed in connecting rod 21, and plunger 22 is located at through hole, connecting rod
21 are reached outside spring housing 1 by the bottom of spring housing 1.The top of spring housing 1 is equipped with attachment base 5, and attachment base 5 is used for
It is connect with connecting rod 21 with external structure.Through-hole and plunger 22 are truncated cone-shaped, and the section radius of the two gradually increases from top to bottom
Greatly.When the side wall of through-hole is arranged one layer of elastic sealing gasket plunger 22 is divided spring housing 1 for upper and lower Liang Ge airtight chamber, column
Fill in 22 elasticity of compression gaskets continue up with meet pressure it is larger when buffering.
In short, the above is only the preferred embodiment of the present invention, it is all according to present utility model application the scope of the patents institute
The equivalent changes and modifications of work should all belong to the covering scope of the utility model patent.
