Description
Technical field
Utility model is related to photovoltaic industry filming equipment, and in particular to a kind of four-bar mechanism fire door for high temperature dispersing furnace
Structure.
Background technology
Tubular type plasma enhanced chemical vapor deposition method（PECVD）And High temperature diffusion furnace apparatus is present photovoltaic industry
One of capital equipment of filming equipment.With the development in market, client is increasing to the capacity requirements of equipment.Due to workshop height
The limitation of degree, the whole height of equipment are restricted, therefore the increase of production capacity mainly increases reative cell.Reative cell internal diameter by
The 305mm of beginning increases to 380mm, is further added by 405mm, 450mm till now.Therefore, in the certain situation of factory building height
Under must reduce the distance between reative cell and reative cell.The distance between reative cell is reduced there are many problems, wherein one
The problem of a main is exactly that two neighboring fire door is avoided to there is interference when rotating.
Utility model content
The purpose of the utility model is to overcome the problems of the above-mentioned prior art to propose a kind of four-bar mechanism door structure.
The technical solution adopted in the utility model is：
A kind of four-bar mechanism door structure, including：One is fixed on the cylinder in rack, the piston of the cylinder and one or four bars
Mechanism connects, and drives the opening and closing of fire door, and the four-bar mechanism includes the fixed plate being arranged in rack, fixed plate with
One end of first connecting rod and second connecting rod is hinged, and the other end of first connecting rod and second connecting rod is hinged with a swing rod.
One end of the swing rod is hinged with second connecting rod, and middle part and the first connecting rod of swing rod are hinged, the other end of swing rod with
Fire door is fixedly connected.
The piston of the cylinder and the middle part of second connecting rod are hinged.
The utility model substitutes bent plate using four-bar mechanism, changes traditional fire door using bent plate shaft as the movement rail in the center of circle
Mark reduces entire fire door mechanism moving radius, not only stable movement, but also saved space.
Description of the drawings
The utility model is described in detail with reference to specific embodiments and the drawings, wherein：
Fig. 1 is the schematic diagram of existing bent plate door structure；
Fig. 2 is the structure diagram of the utility model four-bar mechanism fire door.
Specific embodiment
Fig. 1 is the schematic diagram of the PECVD bent plate fire doors mechanism of existing 405mm internal diameters.The rotating manner of fire door 2 uses cylinder
Control, the piston 3 of cylinder 12 and the middle part of a bent plate 13 are hinged, and one end of the bent plate is hinged with a fixed plate 4, form a rotation
Shaft 1, the other end of the bent plate are fixedly connected with fire door 2.The piston 3 of cylinder pulls bent plate and the fire door 2 being fixed on bent plate
It is moved around rotation axis 1, R1 is movement locus of the fire door under the effect of bent plate fire door mechanism.Outside existing 405mm internal diameters PECVD fire doors
Footpath size is 435mm, and two neighboring fire door minimum range is d1 when pipe is away from 610mm, is 10mm through measuring d1, if pipe is away from becoming smaller
Two neighboring fire door will have interference in the case that fire door increases, it is impossible to work normally.
Fig. 2 be the utility model proposes four-bar mechanism door structure, including the cylinder 12 being hinged in rack, cylinder
Piston 3 is connected with a four-bar mechanism.Four-bar mechanism includes being arranged on fixed plate 4 in rack, fixed plate 4 and first connecting rod 6 and
One end of second connecting rod 7 is hinged, and the other end of first connecting rod 6 and second connecting rod 7 is hinged with swing rod 5, one end of swing rod 5 and stove
Door 2 is fixedly connected.As shown in Fig. 2, first connecting rod 6 hingedly forms first rotating shaft 8, second connecting rod 7 and fixed plate 4 with fixed plate 4
The second shaft of hinged formation 9, first connecting rod 6 and swing rod 5 hingedly form the 3rd shaft 10, and second connecting rod 7 and swing rod 5 are hinged shape
Into the 4th shaft 11.In the embodiment, the piston 3 of cylinder and the middle part of second connecting rod 7 are hinged.When fire door moves, first turn
The position of 8 and second shaft 9 of axis is integrally fixed at motionless in fixed plate, the location following gas of the 3rd shaft 10 and the 4th shaft 11
The active force movement of cylinder.So change traditional fire door using bent plate shaft as the movement locus in the center of circle, make entire fire door mechanism kinematic
Radius reduces, and has saved space.
One end of swing rod 5 is hinged with second connecting rod 7, and the middle part of swing rod 5 and first connecting rod 6 are hinged, the other end of swing rod 5 with
Fire door 2 connects.Second connecting rod 7 and fire door 2 are connected to the both ends of swing rod, when the 4th shaft 11 is compared with the distance between fixed plate
During more than the distance between the 3rd shaft 10 and fixed plate, then swing rod is now in inclined state, and fire door is in the effect of swing rod
Under away from the distance between fixed plate closer to can greatly reduce the scope of activities of fire door.R2 in Fig. 2 is fire door four
The lower movement locus of linkage effect, at this time in the fire door using outer diameter 485mm, pipe is away from for 610mm, two neighboring fire door minimum
Distance is d2, is 29mm through measuring d2, in the case where fire door outer diameter increases pipe away from reduction, it will be apparent that increase adjacent fire door
Between spacing, interference will not be generated.
The utility model utilizes the stability of four-bar mechanism movement, need not set other hinge joints on fire door again,
And there is no interference between two neighboring fire door,.
Only to illustrate the design of the utility model, those of ordinary skill in the art's above specific embodiment exist
Various deformation and variation can be made under the design of the utility model, these are deformed and variation is included in the guarantor of the utility model
Within the scope of shield.
