2, easy to use, and can keep the monnolithic case of door attractive in appearance.
Description of drawings
Fig. 1 is the structure chart of concealed sequencer;
Fig. 2 is that concealed sequencer is installed in the instance graph (doorframe is local to be disconnected) on the doorframe.
The specific embodiment
Describe structure of the present invention in detail below in conjunction with accompanying drawing:
Fig. 1 is a kind of concealed sequencer of the present invention that has, and major part has one to press tongue 1, a torsion spring 2, to press tongue seat 3, a wire rope 4, two screw rods 5, four nuts 6, steel wire cover 7, one back-up ring 8, a block 9, a stage clip 10, a tooth bar seat 11, a rack member 12.
One end of described pressure tongue 1 is oblique tongue, presses tongue 1 to be connected in by screw and presses tongue seat 3 lower ends, and can rotate around tie point A.At the non-oblique tongue end of pressing tongue 1 two through hole is arranged, wire rope 4 is by wherein and be fixedly connected on and press tongue 1.
Described torsion spring 2 is walked around tie point A, and an end is fixed in presses tongue seat 3, one ends to act on pressure tongue 1.When oblique tongue end is subjected to the pressure of door leaf, press tongue 1 to overcome the power of torsion spring 2 and tongue seat 3 is pressed in retraction, after ineffective power, under torsion spring 2 reset force effects, press tongue 1 just to stretch out and press tongue seat 3, (stretching out state) returns to normal.
Described pressure tongue seat 3 is a cuboid, at an end of pressing tongue seat 3 square groove is arranged, and is convenient to press tongue 1 to pack into.Press tongue seat 3 that a through hole is arranged, wire rope 4 is by wherein also moving.
Described wire rope 4 one ends are connected in presses tongue 1, and the other end is connected in rack member 12 ends.During use, wire rope 12 is in tensioned state.
Described two screw rods 5 and four nuts 6 are divided equally into two groups, and one group is used to press tongue 1 exit, and one group is used for rack member 12 exits, and screw rod 5 has a through hole along center line, make wire rope 4 can pass through wherein also can move.Two nuts 6 and a screw rod 5 are used, and can be fixedly connected on certain parts, on the hinge seat as this figure demonstration.
Described steel wire cover 7 is a hollow sleeve, and wire rope 4 can be by wherein also moving, and closely be inserted in respectively in two cored screws 5 at steel wire cover two ends.
Described tooth bar seat 11 is a cuboid, and a through hole is arranged in the centre, and a through hole part is a square hole, and a part is a circular hole, and rack member 12 can move in tooth bar seat 11.
Described rack member 12 is made of tooth bar 121, cuboid 122, cylinder 123 3 parts, and the parts that tooth bar 121 is applied to it according to the controlled system of tooth tilted direction are only along the tooth diagonal crossing, and can not counter motion.Be inserted in stage clip 10 on the cylinder 123, an end of stage clip 10 acts on cuboid 122, and the other end acts on block 9, and block 9 is fixedly connected on the tooth bar seat 11.End at cylinder 122 snaps in back-up ring 8, guarantees that rack member 12 does not eject tooth bar seat 11.
Working method:
One, press tongue retraction process:
As Fig. 1: apply a directed force F (this power F is greater than torsion spring torsion) to pressing tongue 1, press tongue 1 to turn an angle and retraction is pressed in the tongue seat 3 around tie point A, torsion spring 2 reverses certain angle, and torsion increases.Power F acts on rack member 12 by wire rope 4, and it is moved a certain distance along force direction, i.e. rack member 12 certain distance that moves up, and stage clip 10 is in compressive state.So just formed a sequencing: promptly under the effect of F power, press tongue 1 first retraction, thereafter the rack member 12 certain distance (being part retraction tooth bar seat 11) that moves up.
Two, press tongue to stretch out process:
As Fig. 1: will act on and press the power F of tongue 1 to cancel, and under torsion spring 2 reset force effects, press tongue 1 around tie point A backward rotation certain angle and stretch out and press tongue seat 3, (stretching out state) returns to normal.Ineffective power F and under stage clip 10 reset force effects rack member 12 move down certain distance, (stretching out state) returns to normal.So also formed a sequencing: losing under the effect of F power, pressing tongue 1 to stretch out earlier, rack member 12 moves down certain distance (promptly part is stretched out tooth bar seat 11) thereafter.
Three, the example that is installed on the doorframe illustrates:
As Fig. 2, upper end doorframe 13, left and right hinge seat 14,21, left and right hinge 15,20, left and right rectangular doorframe 16,19, left-hand door fan 17, right door leaf 18 are the conventional components on the door.Just hinge seat 14 and hinge seat 21 lengthenings are convenient to tooth bar seat 11 and pressure tongue seat 3 are respectively charged into.
To press tongue seat 3 to pack in the right hinge seat 21, be in the top of hinge 19, and be lower than the top of right hinge 20 when pressing tongue 1 normality (stretching out state), fixedly connected with right rectangular doorframe 19 with screw, screw rod 5 passes the through hole of hinge seat 21, and cooperates clamping with two nuts 6.Steel wire cover 7 passes from upper end doorframe 13.
Equally, with the tooth bar seat 11 left hinge seat 14 of packing into, be in the top of left hinge 15, and be lower than the top of left hinge 15 during rack member 12 normalities (stretching out state), fixedly connected with left rectangular doorframe 16 with screw, another screw rod 5 passes the through hole of hinge seat 14, and cooperates clamping with two nuts 6.
Like this, this concealed sequencer just is fixedly mounted on the doorframe, and is hidden in the doorframe.
Below just explanation this concealed sequencer how to realize that left-hand door fan 17 and right door leaf 18 are in closed condition simultaneously, promptly close earlier by door leaf 18, left-hand door is closed after fanning 17.Otherwise right door leaf 18 is opened, and left-hand door fan 17 just can not be closed.
1, right door leaf 18 process of closing earlier, closing behind the left-hand door fan 17:
As Fig. 2, right door leaf 18 to cut out, right hinge 20 sways, and runs into and presses tongue 1, promptly to pressing tongue 1 to apply a directed force F.Referring to pressing tongue retraction process: under the effect of F power, press tongue 1 retraction, thereafter the rack member 12 certain distance (being part retraction tooth bar seat 11) that moves up, left side hinge 15 does not interfere with rack member 12, left-hand door fan 17 just can be closed, and has so just realized that right door leaf 18 cuts out earlier, left-hand door is closed after fanning 17.
2, right door leaf 18 is opened, left-hand door fan 17 processes that can not close:
As Fig. 2, right door leaf 18 is opened, promptly act on and press the power F of tongue 1 to cancel, referring to pressing tongue to stretch out process: losing under the effect of F power, pressing tongue 1 to stretch out, rack member 12 moves down certain distance (promptly part is stretched out tooth bar seat 11) thereafter.Left side hinge 15 snaps in the rack member 12, and can only move along the oblique direction of tooth, and therefore, left-hand door fan 17 can only be opened along the equal angle of tooth tilted direction, and oppositely (closing direction) motion.When so just having guaranteed that right door leaf 18 does not cut out, left-hand door fan 17 can only be opened and can not close.
Certainly, this sequencer also can be installed in student side's (under situation of lower end doorframe), and its mounting means is identical with working method.
