Description
Technical field
The utility model relates to fire fighting device technical fields more particularly to a kind of rolling screen door can folding and unfolding guide rail.
Background technique
Market, hotel in some large sizes are isolated for fire prevention or other needs through common rolling screen door, every
From position it is often very wide, up to tens meters even rice up to a hundred, in order to which beauty etc. needs, these places are not provided with mountable volume
The column of curtain door guide rail is currently used for the rolling screen door of isolation other than having the place of wall to use fixed guide rail, in no column
Place slided up and down for roller shutter using flexible guide rail, when closing rolling screen door, driving structure first puts down flexible guide rail, then drives volume
Cylinder drives the roller shutter being wrapped on reel to put down roller shutter along flexible guide rail slide downward, then first packs up volume when opening rolling screen door
Curtain packs up flexible guide rail again.But flexible guide rail rigidity is inadequate, and rolling screen door often generates shaking, folding and unfolding guide rail time after closing
It is longer.
Utility model content
The utility model overcomes the deficiencies in the prior art, provide a kind of rolling screen door can folding and unfolding guide rail, can rapid folding and unfolding,
Rolling screen door will not generate shaking after closing.
The utility model is achieved through the following technical solutions：
A kind of rolling screen door can folding and unfolding guide rail, the guide rail slided up and down including bracket, for roller shutter, hydraulic cylinder, oil pressure oil pump,
Locking device and controller；The guide rail includes rigidly fixing rail and rigid movable rail, and cross section is I-shaped；It is described
Retaining rail is set to the top of guide rail, is fixedly connected with bracket, and the top of the retaining rail is tilted towards reel directional smoothing；The activity
Rail is set to guide rail lower part, and the lower end of the upper end and retaining rail is hinged；The cylinder barrel end of the hydraulic cylinder and bracket are hinged,
The head of the piston rod of hydraulic cylinder and the upper outside of active rail are hinged；The hydraulic oil pump is connected hydraulic by hydraulic oil pipe
Oil cylinder, the hydraulic oil pump and controller electrical connection；It is corresponding in its rear lower end straight down that the locking device is set to active rail
Subsurface, the locking device and controller electrical connection.
Further, the locking device is electromagnetic locking device.
The utility model has the beneficial effects that：Guide rail is divided into retaining rail and active rail, liquid is driven using hydraulic oil pump
Compressing cylinder drives active rail rotation, active rail is first put down when closing rolling screen door, then active rail locking is made activity with locking device
Rail cannot shake；After rolling screen door fully opens, first locking device is unlocked, hydraulic cylinder drives active rail rotation to pack up again
Active rail.Active rail folding and unfolding is rapid, and rolling screen door will not generate shaking after closing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is that the active rail of the utility model is in the structural schematic diagram of collapsed state.
Fig. 4 is the A-A cross-sectional view of Fig. 1.
Fig. 5 is the circuit connection diagram of the utility model.
Specific embodiment
As shown in Fig. 1~5, the embodiments of the present invention, a kind of rolling screen door can folding and unfolding guide rail, including bracket 1, for roller shutter
Guide rail 2, hydraulic cylinder 3, oil pressure oil pump 4, electromagnetic locking device 5 and the controller 6 slided up and down；The guide rail 2 includes rigidity
Retaining rail 7 and rigid movable rail 8, cross section are I-shaped；The retaining rail 7 is set to the top of guide rail 2, with bracket 1
It is fixedly connected, the top of the retaining rail 7 is tilted towards reel directional smoothing；The active rail 8 be set to 2 lower part of guide rail, the upper end and
The lower end of retaining rail 7 is hinged；9 end of cylinder barrel of the hydraulic cylinder 3 and bracket 1 are hinged, the piston rod 10 of hydraulic cylinder 3
Head and active rail 8 upper outside it is hinged；The hydraulic oil pump 4 connects hydraulic cylinder 3 by hydraulic oil pipe 11, this is hydraulic
Oil pump 4 and controller 6 are electrically connected；The electromagnetic locking device 5 is set to active rail 8 in the rear corresponding ground in its lower end straight down
Under, the electromagnetic locking device 5 and controller 6 are electrically connected.
Working principle：As shown in figure 3, active rail 8 is in horizontal collapsed state when rolling screen door is in the open state.
When closing rolling screen door, controller 6 drives hydraulic oil pump 4 to work, and hydraulic oil pump 4 drives hydraulic cylinder 3 to eject piston rod 10, piston
Bar 10 pushes active rail 8 to be rotated downward to be vertical state around the hinged place 12 of active rail 8 and retaining rail 7, and later, controller 6 drives
Dynamic electromagnetic locking device 5 works, and prevents active rail 8 from shaking the locking of active rail 8, roller shutter can be closed along 2 slide downward of guide rail
Closed-book curtain door；When opening rolling screen door, after roller shutter is fully opened along 2 upward sliding of guide rail, controller 6 drives electromagnetic locking device
5 unlocks, then hydraulic oil pump 4 is driven to work, so that the piston rod 10 of hydraulic cylinder 3 is bounced back and active rail 8 is driven to be rotated up until water
Movement is packed up in level state, completion.Since the cross section of active rail 8 is in the shape of an " I ", the left and right sides can be used as guide groove for volume
Curtain slides up and down, and after multiple the present embodiment are set side by side, rolling screen door can be connected in flakes, plays buffer action.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, any change or replacement expected without creative work be should be covered within the scope of the utility model.
Therefore, the protection scope of the utility model should be determined by the scope of protection defined in the claims.
