Introduce the structure of utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the sectional view of utility model.
Fig. 2 is the sectional view of Fig. 1 along the A-A line.
Fig. 3 is the part drawing of foundation slab.
With reference to accompanying drawing, the short gripper shoe 4 and fagging 7 one ends of drawing money on credit are hinged on the beam 3 with short pin 5 respectively.The other end 6 is hinged on the backing plate 8 by having strong market potential, and foundation frame 1 also is fixed together with backing plate 8 simultaneously.Short pin 5 and 6 the two ends of having strong market potential all be riveting on beam 3 and foundation frame 1, can not go here and there.Beam 3, short gripper shoe 4, draw money on credit fagging 7 and quadric chain of backing plate 8 compositions.One side of quadric chain, promptly backing plate 8 is fixed on the foundation frame 1.Foundation frame 1 is a troughing plate that have two semicircle flat boards 13.Quadric chain places in the groove of foundation frame 1.Two semicircle dull and stereotyped 13 usefulness screws 12 of foundation frame 1 are installed on the installing plate 2 that is fixed in advance in door and the doorframe cavity.One side relative with backing plate 8 of quadric chain, promptly beam 3 is welded together from the groove the inside with the beam 3 of another quadric chain.The linkage placement that is centrosymmetric is fused by beam 3 on such two, is installed in respectively on door and the doorframe, forms a hinge.Two beams 3 also method of available die casting are made one.
Riveting has a hair(-)pin 9 on the fagging 7 of drawing money on credit.Having strong market potential on hair(-)pin 9 and the short gripper shoe 4 is installed with compression spring 10 between 6.Compression spring 10 is placed in the cover 11.Can slide with the change in length of compression spring 10 between two parts of cover.The two ends of cover are fluted, block hair(-)pin 9 and have strong market potential 6.
The quadric chain of supposing the left side is installed on the doorframe, and the quadric chain on the right is installed on the door.When pushing, power passes on the beam 3 trend that makes it to be moved to the left by the short gripper shoe 4 on the right and the fagging 7 of drawing money on credit.But the backing plate 8 on the left side has propped up the fagging 7 of drawing money on credit.Beam can not move.The backing plate 8 on the right is subjected to the effect of anticlockwise moment of torsion, by rotation counterclockwise.Short gripper shoe 4 up to the right is run into backing plate 8, and door reaches extreme position, stops operating.The fagging 7 of drawing money on credit on the right need overcome the elastic force of compression spring 8 around 6 rotations of having strong market potential in this rotation process.When door soon forwarded extreme position to, hair(-)pin 9 forwarded on the line at two centers of 6 of having strong market potential.Before this position, elastic force makes the fagging 7 of drawing money on credit around having strong market potential 6 by rotation counterclockwise, even door is to the direction rotation of closing.This position one mistake, elastic force make the fagging 7 of drawing money on credit around 6 rotations in the direction of the clock of having strong market potential, even door continues to open.At this moment, short gripper shoe 4 is propped up and can not rotate forward again by backing plate 8, and compression spring 10 makes the door can not be free to revolution again, thereby door can remain on extreme position.At closing time, sliding door and apply the power of pushing doorframe to it.The power of pushing doorframe to forces beam 3 to keep motionless.The backing plate 8 on the right is subjected to clockwise torsional interaction to the commentaries on classics of circling round.Have strong market potential behind the line of centres at 6 center when hair(-)pin 9 has turned over two, the elastic force of compression spring 10 is closed door automatically.When the fagging 7 of drawing money on credit was run into backing plate 8, door was closed fully.Because the action of inertia door continues rotation forward, this moment, beam 3 was inactive with respect to door, and beam 3 drives the short gripper shoe 4 on the left side and the fagging 7 of drawing money on credit rotates.Thereby play cushioning effect.During sliding door, power passes on the beam 3 by the short gripper shoe 4 on the right and the fagging 7 of drawing money on credit, and the trend that makes it to move right keeps relative motionless position with door.The quadric chain on the left side is opened, and compression spring 10 also plays a part same.Push at closing time, and apply the power of pushing doorframe to it.Like this, Men Jike also can inwardly open to external-open, and compression spring 10 can make door remain on the state of closing and reach the limit, and Men Zaiwei reaches and can close automatically before the extreme position.The floor spring that can replace the aluminium alloy door fully.
If two quadric chains are placed axisymmetricly, the beam 3 same block plates of the two are made, and other parts are constant.Then two quadric chains can be opened at synchronization, and Men Nengxiang is one-sided to be reached to a greater extent.
Only need under one-sided situation about opening at door, can replace a quadric chain with foundation slab 14.Beam 3 is welded on the foundation slab 14, or with the method for die casting both is made of one.Foundation slab 14 is fixed on the installing plate 2.Other parts are constant.The structure of utility model is simpler like this.
For the hinge of opening to bilateral, on semicircle dull and stereotyped 13 of foundation frame 1, open a slotted hole 16.The corresponding site of installing plate 2 is also opened a same slotted hole.Pass from the slotted hole 16 of two foundation frames 1 and installing plate 2 with a safety rope 15.Safety rope 15 is one section seizing wire.Again at safety rope 15 two ends with the soldering baffle plate 17 of burn-oning.Like this, safety rope 15 can guarantee that two quadric chains can only have one and open fully in synchronization.At closing time, only need to pull or push, and needn't apply the power of pushing doorframe to.
