Galianconism, it is long-armed at two offer through hole respectively on relative position and a galianconism, be provided with ten on another galianconism
Word groove 21.
Sprocket drive spindle 3 and rack gear be set in the door closer housing 2, and the both ends of gear shaft 3 are by long-armed
Two through holes stretch out door closer housing 2, and one end of the stretching door closer of gear shaft 3 housing 2 is connected with pole 1, passes through pole 1
Rotate, band movable gear shaft 3 rotates.
Rack gear includes 5, at least two times rack 4, main lead resistance leads 7, with returning the resistance quantity of lead 7
Identical direction transaxle 8；Wherein, rack 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 of rack 3 along its length is fixedly connected with one end of main lead 5, and the other end of main lead 5 stretches out
Door closer housing 2, main spring 9 is provided with main lead, one end of main spring 9 holds out against rack 4, and the other end holds out against door closer shell
Body 2, main spring 9 is compressed when rack 4 moves to the direction of main spring 9, main spring 9 is by compress energy storage；Rack 4 is along its length
The other end be fixedly connected with guide pad 6, each one end for returning resistance lead 7 is fixedly connected with guide pad 6 respectively, at each time
Resistance spring 10 is arranged with back on resistance lead 7.
Guide wheel 12, the bottom of guide pad 6 are connected with by guide wheel shaft 11 respectively in the both sides at the both sides of the bottom of guide pad 6 and top
Bottom surface of the guide wheel 12 of portion both sides along door closer housing 2 rolls, and to support rack 4 for linear motion, reduces and door closer shell
The friction of body 2, the two long arm rolls of the guide wheels 12 of the top both sides of guide pad 6 along door closer housing 2, can be that rack 4 is inclined
Heart stress provides the effect of righting and support.
Preferably, rack 4, main lead 5, guide pad 6 and time resistance lead 7 are structure as a whole, and form a special knot
The rack of structure.
Each direction transaxle 8 includes guiding column sleeve 81 and transaxle 82 with bottom, transaxle 82 and lead
The bottom of set 81 is fixedly connected, and the other end for returning resistance lead 7 is inserted in the inside for being oriented to column sleeve 81, the diameter of transaxle 83
Less than the internal diameter of guiding column sleeve 81, it is therefore intended that, when returning resistance 10 stress of spring, time resistance spring 10 moves into guiding column sleeve 81,
The bottom for being oriented to column sleeve 81 plays a part of supporting back resistance spring 10, so as to limit back the movement of resistance spring 10.In transaxle 82
On be stuck in inserted with pin 83, pin 83 in the cross recess 21 of door closer housing 2, the quantity of cross recess 21 is identical with the quantity of pin 83,
Door closer housing 2 is stretched out in one end that transaxle 82 is not connected with being oriented to column sleeve 81.
Preferably, pin 83 is inserted on transaxle 82 close to the position for being oriented to column sleeve 81.
Preferably, it is oriented to column sleeve 81 and transaxle 82 is structure as a whole, forms direction transaxle 8.
Cross recess 21 plays a part of spacing direction transaxle 8, whenever direction transaxle 8 is rotated by 90 °, direction transaxle 8
On the can of pin 83 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 rack 4 moves to the direction for returning resistance spring 10, compression and back resistance spring 10, resistance spring 10 is returned by compress energy storage,
And main spring 9 gradually releases energy, original state is returned to.
In the specific embodiment of the present invention, the quantity for returning resistance spring 10 is three, and three are returned resistance spring 10
Stiffness coefficient ratio is 1:2:4, the rigidity of each time resistance spring 10 is adjusted by direction transaxle 8, it is possible to achieve return resistance spring
10 integral rigidity has eight kinds of 0-7 combination, so as to adjust the elastic energy storage after door is open, makes it proper for the energy closed the door
To benefit, impact, noise are reduced, and it is simple to operate.
It is of course possible to the size and quality according to door, the quantity of resistance spring 10 is increased or decreased back, so that returning resistance spring
10 integral rigidity has different combination changes, to adapt to actual demand.
The automatic door closer structure of adjustable rigidity elastic energy storage provided by the invention is described in detail in the above, below
To the operation principle explanation for the door check that can adjust rigidity elastic energy storage.
During enabling, when external force acts on, pole 1 is with the rotate counterclockwise of movable gear shaft 3, the band of gear shaft 3
The direction of carry-over bar 4 to main lead 5 is moved, and now, main spring 9 returns resistance lead 7 in direction by compress energy storage, rack 4
Moved in the guiding column sleeve 81 of transaxle 8.
During shutdown, after external force is cancelled, main spring 9 release storage elastic potential energy, so as to promote rack 4 to
The direction movement of resistance lead 7 is returned, while is turned clockwise with movable gear shaft 3, during rack 4 moves, 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
Frictional force caused by face 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 balance back resistance spring 10 caused by elastic force, make a concerted effort to be zero, make door is static to get off.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, should all be contained
Cover within protection scope of the present invention.Therefore, protection scope of the present invention described should be defined by scope of the claims.
