Abstract

The utility model discloses an automatic door closing device utilizing revolving deblocking, which is the improvement to the existing automatic door closing device. The door closer or the spring hinge designed with the automatic door closing device utilizing revolving deblocking (the door closer or the spring hinge is just additionally provided with a plurality of tiny parts, the dimension of the door closer or the spring hinge is not change elementarily) can make the door leaf stabilize in a plurality of required angles after being opened. The door leaf can close automatically so long as the users slowly push the door backwards a certain angle when the users need to regain the automatic door closing. An angle opened (usually smaller than 90 DEG) is smaller than the certain angle if no needing to position.

Description

Automatic door closing device utilizing revolving deblocking

The present invention relates to a kind of door engine that utilizes the backhaul release, belong to the architectural hardware class.

Some building door, as: shop, office etc., often adopt spring hinge or door closer to realize automatic door-closing.But in some occasion, as: there is the people frequently to come in and go out, carry object, labeled door etc. in short-term.Require door leaf location when unlatching 90 is spent, in case need, applying a very little strength door leaf again can automatic door-closing, accomplish that this point generally is to prick first-class setting up behind the door foot-operated door system or door, this not only increases building cost, and often to apply a littler strength be difficult to accomplish.Utilize located for the door engine of backhaul release not see as yet so far.

The invention provides a kind of automatic door closing device that utilizes the backhaul release, be designed with when the door closer of this device or spring hinge can make door leaf be opened to 90 degree (or designing other angle) and can rest on the enable possition, as long as need to apply at closing time a very little strength, just but door leaf autoshutdown.As not locating, as long as each the unlatching less than certain angle (generally being designed to less than 90 degree).

Invention is achieved in that when door leaf is opened to certain angle the rotating force of closing the door on the door engine is pinned by this device.When needs recover automatically at closing time, need only door is slightly pushed away the pass certain angle, the locking power of this device promptly is disengaged.

Because the present invention only sets up the function that can locate after a small amount of other part just can make it have unlatching at existing door engine, thereby has saved Men Zhatou, obstacle etc.Reduced construction costs, the location of setting up in addition is part in addition, does not change the physical dimension of some existing automatic door closing device, is convenient to improve existing product.

Embodiment one, Fig. 1 are that this device of reaction is applied in the schematic diagram on the hydraulic pressure door closer.Between the drive link of door closer and axle, set up a cover STATEMENT OF FEDERALLY SPONSORED, drive link and axle are not directly linked, and by the STATEMENT OF FEDERALLY SPONSORED transmission, STATEMENT OF FEDERALLY SPONSORED is formed by two, last slice 1. with the fixing sheet down of axle 2. with drive link fixing last slice 1. have recess 3. and end the top platform 4. descend sheet 2. have dog 5. conciliate boss 6. up and down sheet pass through dog 5. with the mutual transmission of recess interlock 3., but dog 5. than recess 3. undersized make underdrive that certain idle running amount be arranged, 2. sheet rotated under drive link drove when door leaf is opened, 5. interlock is 3. rotated sheet with recess by dog, thus this master of mandrel compression spring, passive rotation makes the last slice top platform that ends 1. gone up 4. 6. stagger with the following sheet boss of separating 2. under the influence of idle running amount.When fan page was opened to design angle (generally deciding 95 degree), 7. the shell fragment that 4. upper slice only top platform is fixed on the housing withstood, and door leaf just stops not return closing.Need at closing time the door leaf page or leaf to be pushed away the pass certain angle.This push away sheet under the rotation direction that the pass just in time changed linkage piece 2. separating in the idle running amount when revolution boss 6. do with under soon shell fragment 7. back down.This moment, former compressed spring began to release energy, thereby door leaf pushes to cut out.

Embodiment two, Fig. 2 are that this device of reaction is applied in the schematic diagram on the two-tube spring hinge.Spring hinge set up a pair of sour jujube pin 1. with cam 2. the sour jujube pin 1. be fixed on half sleeve and 3. go up, 2. cam is fixed on second half sleeve by certain angle and 4. goes up.Driving half when door leaf is opened tucks inside the sleeve when 4. rotating, by pin 6. spring base 5. make tube 8. inner spring 9. button turn to, 1. fall into sour jujube cotter way (11) spring this moment rotating force 8. in spring effect 10. and lived by the sour jujube lock when reaching 90 degree (also can design other angle) sour jujubes pins.Door leaf is auto-closing not.When needs at closing time, close the cam that 4. certain angle half sleeve go up and 2. push up back the sour jujube pin as long as push away, door leaf can recover to close the door automatically function again under spring effect 9. at this moment.Owing to sour jujube cotter way (11) be ramped shaped thus the sour jujube pin 1. can along with half sleeve 4. rotate fall into any one or slip over continuously several sour jujube cotter ways (11) thus can make door leaf stable in several different open degree, yet release is still the same---push away the pass certain angle.

Claims

1, a kind of door engine that utilizes the backhaul release, it by the interlock sheet, end top platform, release boss, dog, recess or sour jujube pin, cam, spring, sour jujube cotter way and hydraulic pressure door closer, spring hinge etc. and partly form.It is characterized in that: transmission rod and the axle of door closer are separated by the dog that arranges on two linkage pieces, recess interlock dog being slightly less than recess, so leave certain idle running amount during positive and negative transmission, with it during to forward rotation, the solution boss that ends on top platform and another linkage piece on the linkage piece staggers, and so only the top shell fragment can fall kayser and live linkage piece; Linkage piece can be in the idle running amount will be ended the top shell fragment by the slope of separating boss and be pushed open during counter-rotating.

2, it is characterized in that by claim 1, described device: pinned by a sour jujube pin card by the convolution of the spring of button or compression or reaction force one.When needing retracting spring power, utilize the idle running double-linked cam of backhaul that the sour jujube pin is pushed open.Thereby the active force that circles round of retracting spring.
