Description
Technical field
This utility model relates to a kind of brake gear, particularly relates to a kind of door roller brake gear with anti-drop function.
Background technology
Rolling screen door is used widely in places such as StoreFront, garage, markets, door roller be used for rolling screen door lifting and under
Fall.Being furnished with brake system in door roller, existing brake system is normally only used for the stopping in rolling screen door lifting process and can not prevent
Pendant, once door roller brake system breaks down, and rolling screen door can be caused quickly to fall, and not only can damage rolling screen door, there is also very
Big potential safety hazard.
Utility model content
This utility model overcomes the deficiencies in the prior art, it is provided that one can prevent rolling screen door from surprisingly quickly falling, tying
The simple brake gear of structure.
This utility model is achieved through the following technical solutions:
The anti-fall brake gear of door roller, including brake disc, the one side of described brake disc is provided with brake block, sets in the middle of brake disc
There is connecting shaft hole, in axis hole, be provided with keyway；The another side of described brake disc is provided with brake assemblies, and described brake assemblies includes getting rid of
Block, friction plate, sleeve and extension spring；The described block that gets rid of is located at the distal shaft side of brake disc, be can move freely, get rid of the paraxial side of block be provided with to
The prominent bar that brake disc axis direction stretches out；Described friction plate is located at the distal shaft side getting rid of block；Described sleeve is enclosed within the outside of prominent bar, and
Brake disc is fixing to be connected, and prominent bar can in sleeve slidably；The fixing connection in one end of described extension spring and the bottom of prominent bar, another
End and the fixing connection of brake disc.Owing to sleeve is fixed on brake disc, and getting rid of block and being fixed on and get rid of block of connection fixed by prominent bar
On friction plate can only make radial motion on brake disc.
Further, described brake assemblies is provided with many groups, and is uniformly distributed circumferentially on brake disc.
Further, described brake assemblies is provided with 3 groups.
During work, being installed on by brake gear in door roller on motor shaft, in the normal lifting process of rolling screen door, door roller turns
Speed is relatively low, and brake gear rotating speed is relatively low, gets rid of block and draws under the effect of extension spring, is now arranged on the friction plate and volume getting rid of on block
There is gap in door machine inner walls, friction plate does not play braking action；When rolling screen door surprisingly quickly drops, brake gear high-speed rotary
Turn, get rid of block under the influence of centrifugal force, overcome the pulling force of extension spring outwards to throw away, be now arranged on the friction plate and rolling door getting rid of on block
Machine inner walls is in close contact and produces frictional force, stops door roller to rotate, thus prevents rolling screen door from quickly dropping.
The beneficial effects of the utility model are: arrange on brake disc and get rid of block, friction plate, sleeve and extension spring, can be at roller shutter
Stop door roller high speed rotating during the unexpected quickly tenesmus of door, can effectively prevent rolling screen door from quickly falling, and whole apparatus structure
Simply.
Accompanying drawing explanation
Fig. 1 is the structural representation of the anti-fall brake gear of this utility model door roller.
Fig. 2 is the scheme of installation of the anti-fall brake gear of this utility model door roller.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, thus protection domain of the present utility model is made apparent clearly
Define.
As shown in Figure 1 and Figure 2, the anti-fall brake gear of this utility model door roller, including brake disc 1, described brake disc 1
One side is provided with in the middle of brake block (being not drawn in figure), brake disc 1 and is provided with connecting shaft hole 2, is provided with keyway 3 in axis hole 2；Described brake
The another side of dish 1 is provided with brake assemblies, and described brake assemblies includes getting rid of block 4, friction plate 5, sleeve 6 and extension spring 7；Described get rid of block 4
Being located at the distal shaft side of brake disc 1, can move freely, the paraxial side getting rid of block 4 is provided with the prominent bar 8 stretched out to brake disc 1 axis direction；
Described friction plate 5 is located at the distal shaft side getting rid of block 4；Described sleeve 6 is enclosed within the outside of prominent bar 8, and the fixing connection of brake disc 1, prominent bar 8
Can in sleeve 6 slidably；The fixing connection in one end of described extension spring 7 and the bottom of prominent bar 8, the other end and brake disc 1 are fixed
Connect.Owing to sleeve 6 is fixed on brake disc 1, and getting rid of block 4 and being fixed on the friction plate 5 got rid of on block of connection fixed by prominent bar 8
Radial motion can only be made on brake disc 1.
For strengthening braking effect, described brake assemblies is provided with 3 groups, and is uniformly distributed circumferentially on brake disc 1.
During work, brake gear is installed in door roller on motor shaft 9, in the normal lifting process of rolling screen door, door roller
Rotating speed is relatively low, and brake gear rotating speed is relatively low, gets rid of block 4 and draws under the effect of extension spring 7, is now arranged on the friction got rid of on block 4
There is gap in sheet 5 and door roller housing 10 inwall, friction plate 5 does not play braking action；When rolling screen door surprisingly quickly drops, brake
Device high speed rotating, gets rid of block 4 under the influence of centrifugal force, overcomes the pulling force of extension spring 7 outwards to throw away, is now arranged on and gets rid of on block 4
Friction plate 5 and door roller housing 10 inwall be in close contact and produce frictional force, stop door roller to rotate, thus prevent rolling screen door fast
Speed tenesmus.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model does not limit to
In this, any change expected without creative work or replacement, all should contain within protection domain of the present utility model.
Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims are limited.
