Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of heretofore described pneumatic mechanism；
Fig. 3 is the top view of heretofore described outer box internal structure.
Detailed description of the invention
The invention will be further described with detailed description of the invention below in conjunction with the accompanying drawings.
With reference to Fig. 1, the pneumatically spring of pressure adjustable of the present invention, the pneumatically spring of pressure adjustable, including outer box
1, panel 5, inner shell 2, rotating shaft 6 and cam 62.Described inner shell 2 is arranged in outer box 1 inner chamber, its surrounding outer wall and outer box 1 inwall
Between be respectively equipped with set screw 4, as shown in Figure 3.Described panel 5 is fixed on the end face of inner shell 2.The bottom of described rotating shaft 6
Be arranged on the base plate of inner shell 2 by pressure bearing 64, the top of described rotating shaft 6 be provided with connecting pin 61, connecting pin 61 to
On run through panel 5；Being provided with gland 22 on the end face of described inner shell 2, described rotating shaft 6 is connected with gland 22 by bearing 63.
Described inner shell 2 is provided with and is driven by rotating shaft 6, and can by the cam 62 being arranged in rotating shaft 6 react on turn
The pneumatic mechanism 3 of axle 6.
With reference to Fig. 2, described pneumatic mechanism 3 includes cylinder 30, the fairlead 35 being fixed on cylinder 30 front end, is fixed on cylinder
The rear closure 39 of 30 tail ends, it is arranged on the piston apparatus of cylinder 30 front portion and is arranged on the regulator at cylinder 30 rear portion.
Described piston apparatus includes that piston rod 32 and secondary piston 37, described piston rod 32 run through fairlead 35, and its tail end is stretched
Entering in cylinder 30, described secondary piston 37 is fixed on the tail end of piston rod 32.Described regulator includes regulator bolts 31 He
Back piston 38, described regulator bolts 31 Screw assembly is in rear closure 39, and its inner extend in cylinder 30, described back piston 38
It is fixed on the inner of regulator bolts 31；Cavity between described secondary piston 37 and back piston 38 is air cavity 34, fills in air cavity 34
There is compressed gas.
Described cam 62 entirety is ellipsoidal structures, and the sidewall corresponding to the two ends of its long diameter is respectively equipped with arc
High point groove, the sidewall corresponding to the two ends of its short diameter is respectively equipped with the low spot groove of arc, described low spot groove deep
Degree is more than the degree of depth of high point groove.The center of described cam 62 is vertically fixed in rotating shaft 6；On the front end of described piston rod 32 admittedly
Surely driving head 33, the front end face of described driving head 33 is had to be provided with the arc that can match respectively with high point groove, low spot groove
Convex surface.
When installing and using, pneumatically spring of the present invention is embedded in below glass door body, and by connecting pin 61 with
Glass door body is connected.Glass door body is under closing door state, and one of them low spot groove of cam 62 is stuck in the arc of driving head 33
On shape convex surface.During enabling, need firmly outwards push or inwardly pull, make door body around the axle center half-twist of connecting pin 61, in
Being that rotating shaft 6 synchronizes axle center half-twist with connecting pin 61, cam 62 rotates with rotating shaft 6, and the arc convex of driving head 33 departs from low
Point groove, piston rod 32 retraction in cylinder 30；When cam 62 rotates 90 ° with rotating shaft 6, the arc convex of driving head 33 snaps in
In one of them high point groove of cam 62, door body is positioned at door opening state；Owing to the degree of depth of high point groove is shallower, work as door opener
When walking out doorway or enter in door, exerting a force door body opposite direction a little with hands, it is high that the arc convex of driving head 33 just can be made to depart from
Point groove, piston rod 32 return action, protruding from cylinder 30, thus promote cam 62 to rotate backward, and then by rotating shaft 6
Drive door body rotates, and when cam 62 rotates backward 90 °, the arc convex of driving head 33 snaps in again the low spot groove of cam 62,
Door body is in pass door state, and owing to the degree of depth of low spot groove is relatively deep, unless door body is applied enough power, door body will not be opened automatically
Open.
On described cylinder 30 inwall, the position corresponding with secondary piston 37 stroke is provided with axial damping slot 30a, described
The cross section of damping slot 30a is triangular in shape, and its degree of depth is incremented by from front to back.Secondary piston 37 traveling forward or backward in cylinder 30
During, compressed gas is known from experience by damping slot 30a flowing between cavity on front side of air cavity 34 and secondary piston 37, and damping slot 30a
The triangular structure that the degree of depth is incremented by from front to back so that piston rod 32 in return action, outwardly directed process from cylinder 30
In, secondary piston 37 runs, during this, along with secondary piston 37 front from damping slot 30a rear portion to the anterior of damping slot 30a
30a is more and more shallow for damping slot, and flow of the compressed gas dynamic resistance increases, and then the process making door body be automatically switched off is by the slowest.
For the ease of regulating the pressure in air cavity 34 by operation regulator bolts 31, the afterbody shell wall of inner shell 2 is pacified
Dress tail plug 21.When needing to carry out pressure regulation, unload lower tail plug 21, rotate regulator bolts 31.If the pressure that need to increase in air cavity 34,
Rotating regulator bolts 31 makes it promote back piston 38 to move to secondary piston 37, reduces distance therebetween；If air cavity need to be reduced
Pressure in 34, rotates backward regulator bolts 31 so that it is pull back piston 38 to move to the direction away from secondary piston 37, increases two
Distance between person.
In order to strengthen the sealing property of pneumatic mechanism 3, piston rod 32 is fixed with oil sealing base 36, described oil sealing base
36 front sides being positioned at secondary piston 37, equipped with oil sealing on oil sealing base 36.Additionally, distinguish on described secondary piston 37 and back piston 38
It is cased with O.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
