Description
Technical field
It the utility model is related to rolling screen door technical field, more particularly to a kind of rolling screen door auxiliary brake.
Background technology
Electric rolling door is used widely in places such as StoreFront, garage, markets, and electric rolling door is usually by door roller
Spool is driven to rotate by chain-drive mechanism, the reel outside spool is rotated with spool, and drive is wrapped on reel
Door curtain guide rail of the door curtain along door opening both sides slide up and down to carry out switch gate.After use after a while, Chain conveyer
The driving chain of mechanism can fatigue wear, it is elongated fluff, often produce de- chain, serious meeting chain rupture, once occur de- chain or
Chain rupture, door curtain will down fall in the presence of self gravitation, door curtain can not only be damaged, also in the presence of serious potential safety hazard.
Utility model content
The utility model overcomes the deficiencies in the prior art, there is provided a kind of de- chain or chain rupture to occur in driving chain
In the case of, the rolling screen door auxiliary brake that prevents door curtain from down falling.
The utility model is achieved through the following technical solutions：
A kind of rolling screen door auxiliary brake, including supporting plate, spool and reel；The supporting plate is divided into above door opening
On the wall of both sides, spool both ends and supporting plate rotation connection, drum sheath are fixedly connected outside spool with spool；Also include getting rid of
Ball extension spring, get rid of ball, ratchet, sleeve pipe, guide rod, ratchet, ratchet baffle plate, guide rod spring, trigger board and connecting rod；It is described to get rid of ball extension spring
One end connects spool, and ball is got rid of in other end connection；The ratchet is fixedly arranged on spool；Described sleeve pipe is above ratchet side with propping up
Frame plate is fixedly connected, and guide rod is through in sleeve pipe and is slidably connected with it, and ratchet is in the sleeve pipe of lower end of the guide rod, the pawl point of the ratchet
Above the ratchet of ratchet；Described ratchet baffle plate one end is laterally pierced into casing part and is connected with cannula slide, and the other end is located at
Jacket exterior；The guide rod spring housing is located in sleeve pipe outside guide rod, its one end ejection sleeve upper end, the downward ejection spine of the other end
Pawl makes the pawl point of ratchet be pressed on ratchet baffle plate；The trigger board is laterally located at getting rid of above ball, and its one end and supporting plate are hinged, separately
One end and one end of connecting rod are hinged, and one end that the other end and ratchet baffle plate of the connecting rod are located at jacket exterior is hinged.
When door curtain normally declines, reel and spool normal rotation, due to the effect of centrifugal force, get rid of ball and outwards throw away, but
Because now reel and spool rotating speed are relatively low, get rid of ball and hit less than trigger board；When de- chain or chain rupture occur for driving chain, door curtain is fast
Speed is fallen, and reel and spool rotating speed improve rapidly, is got rid of ball and is overcome the pulling force for getting rid of ball extension spring outwards to throw away, strikes trigger board, is touched
Hair plate is pulled out ratchet baffle plate by connecting rod out of sleeve pipe, and ratchet moves downward in the presence of guide rod spring, its pawl point ejection
In the ratchet root of ratchet, pawl wheel is prevented, so as to prevent spool turns, prevents door curtain from continuing down to fall.
Further, it is described get rid of ball extension spring and get rid of ball be equipped with it is multiple, and along spool even circumferential set.It can strengthen getting rid of ball pair
The impact effects of trigger board.
The beneficial effects of the utility model are：When de- chain occurs for driving chain or chain rupture causes door curtain quickly to fall, lead to
Cross get rid of ball overcome get rid of ball extension spring pulling force hit trigger board, ratchet ejection is prevented spool and reel on the ratchet of ratchet
It is rotated further, so as to prevent door curtain from continuing down to fall.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 A-A sectional views.
Fig. 3 is Fig. 1 B-B sectional views.
Embodiment
As shown in Figures 1 to 3, embodiment of the present utility model, a kind of rolling screen door auxiliary brake, including supporting plate 1, volume
Axle 2 and reel 3；The supporting plate 1 is divided into above door opening on the wall of both sides, and the both ends of spool 2 and supporting plate 1 are rotatablely connected,
Reel 3 is enclosed on the outside of spool 2 and is fixedly connected with spool 2；Also include getting rid of ball extension spring 4, getting rid of ball 5, ratchet 6, sleeve pipe 7, guide rod 8, spine
Pawl 9, ratchet baffle plate 10, guide rod spring 11, trigger board 12 and connecting rod 13；One end connection spool 2 for getting rid of ball extension spring 4, it is another
Ball 5 is got rid of in end connection；The ratchet 6 is fixedly arranged on spool 2；Described sleeve pipe 7 is fixed above the side of ratchet 6 with supporting plate 1 to be connected
Connect, guide rod 8 is through in sleeve pipe 7 and is slidably connected with it, and in the sleeve pipe 7 of the lower end of guide rod 8, the pawl point of the ratchet 9 is located at ratchet 9
The top of ratchet 14 of ratchet 6；Described one end of ratchet baffle plate 10 is laterally pierced into the bottom of sleeve pipe 7 and is slidably connected with sleeve pipe 7, other end position
Outside sleeve pipe 7；The guide rod spring 11 is enclosed on outside guide rod 8 in sleeve pipe 7, the upper end of its one end ejection sleeve pipe 7, the other end to
Lower ejection ratchet 9 makes the pawl point of ratchet 9 be pressed on ratchet baffle plate 10；The trigger board 12, which is laterally located at, gets rid of the top of ball 5, its one end
Be hinged with supporting plate 1, one end of the other end and connecting rod 13 is hinged, and the other end and ratchet baffle plate 10 of the connecting rod 13 are located at sleeve pipe
One end outside 7 is hinged.
When door curtain normally declines, reel 3 and the normal rotation of spool 2, due to the effect of centrifugal force, get rid of ball 5 and outwards throw away,
But because now reel 3 and the rotating speed of spool 2 are relatively low, get rid of ball 5 and hit less than trigger board 12；When de- chain or chain rupture occur for driving chain
When, door curtain quickly falls, and reel 3 and the rotating speed of spool 2 improve rapidly, get rid of ball 5 and overcome the pulling force for getting rid of ball extension spring 4 outwards to throw away, hit
Trigger board 12 is hit, trigger board 12 is by the pull-out out of sleeve pipe 7 by ratchet baffle plate 10 of connecting rod 13, and ratchet 9 is in guide rod spring 11
Being moved downward under effect, its pawl point ejection prevents ratchet 6 from rotating in the root of ratchet 14 of ratchet 6, so as to prevent reel 3 from rotating,
Prevent door curtain from continuing down to fall.
In the present embodiment, it is described get rid of ball extension spring 4 and get rid of ball 5 be equipped with 4, and set along the even circumferential of spool 2.It can strengthen
Get rid of impact effects of the ball 5 to trigger board 12.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
