Word groove 21.
Sprocket drive spindle 3 and rack gear are set in door closer housing 2, and the two ends of gear shaft 3 pass through on long-armed
Two through holes stretch out door closer housing 2, and gear shaft 3 stretches out one end of door closer housing 2 and is connected with pole 1, by pole 1
Rotate, band movable gear shaft 3 is rotated.
Rack gear includes tooth bar 4,5, at least two times resistance lead columns 7 of main lead column and returns the resistance quantity of lead column 7
Identical direction transaxle 8；Wherein, tooth bar 4 is meshed with gear shaft 3, is done by the forward or reverse band carry-over bar 4 of gear shaft 3
Move repeatedly, the one end along its length of tooth bar 3 is fixedly connected with one end of main lead column 5, and the other end of main lead column 5 stretches out
Door closer housing 2, is provided with main spring 9 in main lead column, and one end of main spring 9 holds out against tooth bar 4, and the other end holds out against door closer shell
Body 2, main spring 9 is compressed when tooth bar 4 is moved to the direction of main spring 9, and main spring 9 is by compress energy storage；Tooth bar 4 is along its length
The other end be fixedly connected with guide pad 6, each return resistance lead column 7 one end be fixedly connected with guide pad 6 respectively, in each time
Resistance spring 10 is arranged with back in resistance lead column 7.
Guide wheel 12, the bottom of guide pad 6 are connected with by guide wheel shaft 11 respectively in the both sides of the bottom of guide pad 6 and the both sides at top
The guide wheel 12 of portion both sides is rolled along the bottom surface of door closer housing 2, to support tooth bar 4 for linear motion, is reduced and door closer shell
The friction of body 2, the guide wheel 12 of the top both sides of guide pad 6 along door closer housing 2 two arm rolls long, can be inclined for tooth bar 4
Heart stress provides the effect of righting and support.
Preferably, tooth bar 4, main lead column 5, guide pad 6 and time resistance lead column 7 are structure as a whole, and constitute a special knot
The tooth bar of structure.

Cross recess 21 plays a part of spacing direction transaxle 8, whenever direction transaxle 8 is rotated by 90 °, direction transaxle 8
On pin 83 can just be stuck in cross recess 21, can be driven back when direction transaxle 8 rotates resistance spring 10 rotate, so as to adjust
Return the rigidity of resistance spring 10.
When tooth bar 4 is moved to the direction for returning resistance spring 10, compression and back resistance spring 10 returns resistance spring 10 by compress energy storage,
And main spring 9 gradually releases energy, original state is returned to.
In a specific embodiment of the present utility model, the quantity for returning resistance spring 10 is three, and three are returned resistance spring
10 stiffness coefficient ratio is 1:2:4, each time rigidity of resistance spring 10 is adjusted by direction transaxle 8, it is possible to achieve return resistance
The integral rigidity of spring 10 has the combination of eight kinds of 0-7, so as to adjust the elastic energy storage after door is open, makes its energy for Gong closing the door
Amount is just right, reduces impact, noise, and simple to operate.
It is of course possible to size and quality according to door, the quantity of resistance spring 10 is increased or decreased back, so that returning resistance spring
There are 10 integral rigidity different combination changes to adapt to actual demand.
The above is described in detail the automatic door closer structure of the adjustable rigidity elastic energy storage of the utility model offer,
Below to can adjust the operation principle explanation of the door check of rigidity elastic energy storage.
During enabling, when external force is acted on, pole 1 is with the rotate counterclockwise of movable gear shaft 3, the band of gear shaft 3
Carry-over bar 4 is moved to the direction of main lead column 5, and now, main spring 9 hinders lead column 7 in direction by compress energy storage, returning for tooth bar 4
Moved in the guiding column sleeve 81 of transaxle 8.
During closing the door, after external force is cancelled, main spring 9 release storage elastic potential energy so that promote tooth bar 4 to
The direction movement of resistance lead column 7 is returned, while band movable gear shaft 3 turns clockwise, during tooth bar 4 is moved, main spring 9
Elastic force is gradually reduced, and the elastic force for returning resistance spring 10 gradually increases, and door first accelerates to slow down afterwards during closing, due to each contact
The frictional force that face causes is identical with the Impact direction for returning resistance spring 10, and the speed of final door is zero, and this moment, total frictional force can be anti-
To, for balancing back the elastic force produced by resistance spring 10, make a concerted effort to be zero, make that door is static to get off.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any one skilled in the art can readily occur in change in the technical scope that the utility model is disclosed
Or replace, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should be described with power
The protection domain that profit is required is defined.
