Description
Technical field
The utility model is related to rolling screen door, specifically refers to a kind of spool brake gear.
Background technology
Rolling screen door is cascaded with the door piece of multi-joint activity, in fixed slideway, using door top spool in
Door above and below heart rotation.Larger in some houses, bank or market door opening, the place side of playing of ground door body is installed in inconvenience
Just, fast opening is acted on.In order that rolling screen door can be operated at the uniform velocity, brake gear, traditional brake are provided with rolling screen door
Device brake failure after rotating shaft is out of order, causes rolling screen door to fall down rapidly, causes potential safety hazard；Therefore, for above-mentioned
The solution for the problem of existing is research purpose of the present utility model.
Utility model content
In view of the above-mentioned problems of the prior art, the utility model is to provide a kind of spool brake gear, Neng Gouyou
Effect solves the problem of above-mentioned prior art is present.
The technical solution of the utility model is：In being fixed with a kind of spool brake gear, including rotating shaft, the rotating shaft
Outer shroud is provided with the outside of ring, the inner ring, and outer shroud is arranged in frame, the inner ring presses circular array close to the edge of rotating shaft
Row are provided with three draw ring arrangement grooves；The draw ring arrangement bottom land end is connected with draw ring, the draw ring not with draw ring arrangement bottom land
One end of end Joint is connected with sliding block；The edge that the outer shroud is close to frame is provided with three spring assemblies by annular array
Groove；Three spring assembly grooves are correspondingly arranged with the draw ring arrangement groove, and compression spring is fixed with spring assembly groove, described
One end affixed with spring assembly groove is not connected with brake block to compression spring；The brake block and the opposed side of compression spring
It is provided with a positioning wedged block.
Advantage of the present utility model：A kind of spool brake gear, when rotating shaft is out of order, inner ring can be operated rapidly, from
The heart is acted on under Action of Gravity Field, and draw ring is stretched out, and the sliding block of draw ring one end can be made to get to positioning wedged block；Positioning wedged block is struck off
Afterwards, compression spring extends, and just the brake block of compression spring end blocks rotating shaft；So as to serve rapid braking action, make door
Do not continue to fall down, improve rolling screen door security.The utility model is simple in construction, is adapted to be widely popularized.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
For the ease of it will be appreciated by those skilled in the art that existing make embodiment combination accompanying drawing into one to structure of the present utility model
Step is described in detail：
With reference to Fig. 1, a kind of spool brake gear, including rotating shaft 1 is fixed with outside inner ring 2, the inner ring 2 in the rotating shaft 1
Side is provided with outer shroud 3, and outer shroud 3 is arranged on frame（It is not drawn into）On, the inner ring 2 presses circular array close to the edge of rotating shaft 1
Row are provided with three draw ring arrangement grooves 21；The bottom of draw ring arrangement groove 21 is connected with draw ring 4, and the draw ring 4 is not filled with draw ring
The one end for putting the bottom Joint of groove 21 is connected with sliding block 5；The edge that the outer shroud 3 is close to frame is provided with three by annular array
Individual spring assembly groove 31；Three spring assembly grooves 31 are correspondingly arranged with the draw ring arrangement groove 21, in spring assembly groove 31
Compression spring 6 is fixed with, one end affixed with spring assembly groove is not connected with brake block 7 to the compression spring 6；The brake block
7 are provided with a positioning wedged block 8 with the opposed side of compression spring 6.
A kind of spool brake gear, when rotating shaft 1 is out of order, inner ring 2 can be operated rapidly, in centrifugal action and Action of Gravity Field
Under, draw ring 4 is stretched out, and the sliding block 5 of the one end of draw ring 4 can be made to get to positioning wedged block 8；After positioning wedged block 8 is struck off, bullet is compressed
Spring 6 extends, and just the brake block 7 of the end of compression spring 6 blocks rotating shaft 1；So as to serve rapid braking action, door is set not continue
Fall down, improve rolling screen door security.The utility model is simple in construction, is adapted to be widely popularized.
The foregoing is only preferred embodiment of the present utility model, it is all according to present utility model application the scope of the claims done it is equal
Deng change and modification, it should all belong to covering scope of the present utility model.
