Abstract

The utility model provides an automatic close sequence controller for door leaves, which matches with an automatic apparatus for close door to use, mainly comprising a bracket, a reciprocating pin, a swinging rod, a spring, etc. When closing the door, the swinging rod bunts the door leaf which is not supposed to be closed firstly. Until the door leaf which is supposed to be closed firstly is closed in position to bunt the reciprocating pin, making the reciprocating pin move afterwards, a stop dog arranged on the reciprocating pin is released and contacts the inner end of the swinging rod. Thereby, the second door leaf is closed in position. The utility model can be universally applied to hotels, restaurants, and apartments.

Description

Automatic close sequencing controller for double-acting hinged door leaves

The utility model relates to a kind of and the automatic closing sequence controller of the matching used door leaf of splitting in pairs of door check.

Nowadays, the hotel of air conditioner facility, the unlatching of the hinged door leaf in the restaurant are generally all controlled by door check, in order to strengthen the sealing of door leaf, two fan doors often are designed to the Yishanmen edge on the doorframe limit that closes up the place and are " " shape or " " tee section, another fan doorjamb is " " shape or " " tee section, so that two limits intermesh, thus the inside and outside circulation of air of isolating chamber effectively.Obviously, can produce a new problem, at closing time promptly at this point, the correct priority closing sequence of only guaranteed two fan doors can guarantee that the doorframe limit of two fan doors is meshed well, and door leaf closes up closely, otherwise fail two doorframe limits of good engagement and can cause obvious slit at the place of closing up, influence its sealing.So the closing sequence of control door leaf seems particularly important, and does not still have this control device at present.

The purpose of this utility model just provides a kind of and the supporting use of door check is closed the controller of usefulness to control two fan door automatic sequences.

To achieve these goals, hinged door leaf of the present utility model cuts out automatically and comprises along the control device: a support, and it is fixed on doorway arch and two commissure opposite positions in use; One reciprocating member is installed on the described support versatilely, but along continuous straight runs is perpendicular to sliding before and after the frame of doorway; One fork, it stretches into inner end in the described support and is connected in one rotationally and is fixed on the pivot pin of support, and its overhanging end that stretches out described support can be swung in horizontal plane around described pivot pin; The overhanging end that makes described fork at the elastic component and that one on the described support is drawn forward described reciprocating member all the time by after the elastic component of swing forward; A side that is positioned at fork on the described reciprocating member is provided with a block; The position of described pivot pin should make when initial position (i.e. door standard-sized sheet), and described block just props up the inner end of described fork and stops fork to be swung backward, and holding by one of door leaf of described reciprocating member stretched out described support; On described support, be provided with a stopping means, in order to closing, block described fork unlikely position of crossing it under described elastic component pulling force during right door leaf standard-sized sheet perpendicular to the doorway frame when the left-hand door fan near one of door leaf side.

When adopting the supporting use of automatic closing sequence controller of door leaf that such scheme makes and door check, it is installed in the doorframe top, fork can withstand the door leaf that should not at first close when two fan doors closed up, treat that the door leaf that must at first cut out cuts out and put in place, this door leaf promotes to move behind the reciprocal pin contacting of the block disengaging that makes on this pin and fork fixed end, fork swing allows closes the door leaf that is obstructed and closes and put in place, controls the closing sequence of two fan doors thus, has guaranteed closely to close up after two fan doors are closed.

In order to deepen understanding to the utility model purpose and structure, below just in conjunction with the accompanying drawings an embodiment of the present utility model is done a detailed description.

Fig. 1 is the positive view of the utility model one embodiment.

Fig. 2 is the sectional view of the utility model one embodiment.

Fig. 3 is the work schematic diagram that the utility model one embodiment is installed in the doorway arch when using.

Referring to Fig. 1 and Fig. 2, the automatic closing sequence controller of the utility model door leaf mainly comprises support 9, back and forth sells 1, fork 2, extension spring 5,6 etc.Support 9 utilizes rivet by a base plate 10, a top board 13 and the header board 11 with identical " Jiong " tee section and a back plate 12 and forms.Central part at header board 11 and back plate 12 has two relative round tube holes respectively.Be provided with isolated one spacing shoulder block 14 and on the interlude of described reciprocal pin 1 mutually towards the inside frustum of a cone block 3 that closes up of shoulder block direction, two ends then are cylindrical.This pin is threaded onto the two through hole of forward and backward plate movably with two ends in advance and is folded in the support 9 when assembling.Described reciprocal pin 1 vicinity that is positioned on support 9 is provided with a fixing circular shaft pin 4.Other has fork 2 to be folded between top board 13 and the base plate 10, and the one end is sleeved on the described pivot pin 4 movably by a through hole, and the protruding support 9 of its other end can rotate around pivot pin 4.The position of described pivot pin 4 should set make when described block 3 at initial position, can rely on the contacting of inner end of block 3 and fork 2 when promptly back and forth the spacing shoulder block 14 on the pin 1 is near support header board 11, stop the overhanging end of fork 2 to be swung backward, and pushed inwards when disengaging with fork 2 when reciprocal pin 1, fork 2 overhanging ends can rearward freely swing.Smooth in order to guarantee that door leaf contacts with the overhanging end of fork 2, but the roller 8 of rotation is housed on the overhanging end of described fork 2; For reciprocal pin 1 after moving and the fork 2 after the swing are resetted forward, impose on one by spring on the block 3 on the reciprocal pin 1 and on fork 2 inner ends respectively and will back and forth sell forward and draw, fork 2 is remained the elastic pulling force of swinging before the clockwise direction.As shown in Figure 1, extension spring 5 is housed, between rivet 18 and the fork 2 extension spring 6 is housed at rivet 15 with between back and forth selling 1.In order to close, make described fork 2 unlikely position of crossing it under described extension spring 6 pulling force, seamed edge 20 formations one stopping means of close the described fork 2 on the header board on the described support during right door leaf standard-sized sheet perpendicular to the doorway frame when left-hand door fan.

Fig. 3 shows the operating principle that door leaf cuts out the front and back present embodiment, wherein 19,20 is two door leafs, the 21st, doorframe top, access, automatically the fork 2 in the closing sequence controller stretches out the fastening position at door leaf 20 automatically after door leaf is opened, 1 fastening position of stretching of described reciprocal pin at door leaf 19, controller is the initial position state, fork 2 can not be swung, the two fan doors that the door check operation is opened close up, if door leaf 20 at first cuts out, running into fork 2 is obstructed to close and puts in place, withstanding described reciprocal pin 1 after having only the door leaf of allowing 19 at first to close moves it backward, force this back and forth the block 3 on the pin 1 break away from and the contacting of fork 2 inner ends, at this moment door leaf 20 overhanging end that promotes forks 2 is swung and is finished closing motion.
