Abstract
The present invention relates to a kind of anti-fall brake disc of door roller and brake base, including brake disc and brake base, brake disc is equipped with bow arm, bend arm and be equipped with ratchet, brake base is also equipped with ratchet, forms ratchet mechanism, it quickly falls to can effectively prevent rolling screen door, and whole device is simple in structure.
Description
Technical field
The present invention relates to door roller technical field more particularly to a kind of anti-fall brake discs of door roller and brake base.
Background technology
Rolling screen door is used widely in places such as StoreFront, garage, markets, door roller be used for rolling screen door promotion and under
Drop.Be furnished with brake system in door roller, the stopping that existing brake system is normally only used in rolling screen door lifting process and cannot prevent
Pendant, once door roller brake system breaks down, can cause rolling screen door quickly to be fallen, can not only damage rolling screen door, there is also very
Big security risk.
Chinese Patent Application No. 201520769556.7 discloses a kind of anti-fall door roller brake disc, including disk body, the disk
The one side of body is equipped with friction plate, and connecting shaft hole is equipped among disk body, keyway is equipped in axis hole；It is characterized in that：The disk body is another
Distal shaft side on one side set there are two it is symmetrically arranged it is anti-fall get rid of hoof, the anti-fall hoof that gets rid of is arc-shaped, and one end and disk body activity connect
It connects, the other end is connected with each other by tension spring；It is equipped with brake pad at the top of the anti-fall arc for getting rid of hoof.Although can effectively prevent roller shutter
Door falls, but rolling screen door falls speed when declining, and the anti-fall hoof that gets rid of inwardly closes up return under the action of tension spring, and rolling screen door can also be after
Continuous to fall down, so there is also certain hidden danger, especially some large-scale rolling screen door, hidden danger are bigger.
Invention content
The present invention overcomes the deficiencies in the prior art, provide it is a kind of can prevent rolling screen door from surprisingly quickly falling, structure letter
Single anti-fall brake disc of door roller and brake base.
The present invention is achieved by the following technical solutions：A kind of anti-fall brake disc of door roller and brake base, including stop
Hull and brake base, the brake disc include disk body, and the one side of disk body is equipped with friction plate, connecting shaft hole is equipped among disk body,
Keyway is equipped in axis hole；The distal shaft side of the disk body another side is set there are two symmetrically arranged anti-fall bow arm, the anti-fall bow arm
Arched, one end is flexibly connected by fixed pin with brake disc, and the other end is connected with each other by tension spring；The anti-fall bow arm rest
The outside of nearly tension spring one end is equipped with ratchet A, the ratchet A in distribution counterclockwise；The brake base bottom is equipped with round fixed
Seat, fixed seat center are equipped with motor axis hole, and a cylindrical portion is additionally provided in fixed seat, and inside forms a cavity and brakes for placing
Disk, cylindrical portion inner edge are equipped with multigroup ratchet B, and the ratchet B is in distribution clockwise.
Further, the fixed seat edge also Circle-Array shows multiple mounting holes.
When work, brake disc is installed in door roller on motor shaft, in the normal lifting process of rolling screen door, door roller rotating speed
Relatively low, brake disk rotating speed is relatively low, and anti-fall bow arm closes up under the action of tension spring, and the ratchet A on anti-fall bow arm is arranged at this time
There are gaps with the ratchet B on brake base, do not play braking action；When the unexpected quickly tenesmus of rolling screen door, brake disc high speed is revolved
Turn, anti-fall bow arm under the influence of centrifugal force, overcomes the pulling force of tension spring to throw away outward, and the ratchet on anti-fall bow arm is arranged at this time
The ratchet B of A and brake base mutually tightly engages generation brake force, prevents door roller from rotating, under preventing rolling screen door quick
Pendant.
The beneficial effects of the invention are as follows：On brake disc and anti-fall bow arm, tension spring and ratchet are set on pedestal, it can be in roller shutter
Door roller high speed rotation is prevented when door surprisingly quickly drops, and be can effectively prevent rolling screen door and is quickly fallen, and whole device structure
Simply, performance is stablized.
Description of the drawings
Fig. 1 is the structural schematic diagram of brake disc of the present invention.
Fig. 2 is the structural schematic diagram of brake base of the present invention.
Fig. 3 is vertical view of the present invention.
Specific implementation mode
The preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
A kind of anti-fall brake disc of door roller as shown in FIG. 1 to FIG. 3 and brake base, including brake disc 1 and brake base 2,
The brake disc 1 includes disk body 3, and the one side of disk body 3 is equipped with friction plate 4, connecting shaft hole 5 is equipped among disk body 3, is equipped in axis hole
Keyway 6；The distal shaft side of 3 another side of the disk body is set there are two symmetrically arranged anti-fall bow arm 7, and the anti-fall bow arm 7 is arched,
One end is flexibly connected by fixed pin 8 with disk body 3, and the other end is connected with each other by tension spring 9；The anti-fall bow arm 7 is close to drawing
The outside of 9 one end of spring is equipped with ratchet A10, the ratchet A10 in distribution counterclockwise；2 bottom of the brake base is equipped with round solid
Reservation 11,11 center of fixed seat are equipped with motor axis hole（It is not identified in figure）, a cylindrical portion 12, internal shape are additionally provided in fixed seat 11
It is equipped with multigroup ratchet B13 for placing brake disc 1,12 inner edge of cylindrical portion at a cavity, the ratchet B13 is in distribution clockwise.
11 edge of the fixed seat also Circle-Array shows multiple mounting holes 14.
When work, brake base 2 is fixed on door roller, brake disc 1 is installed in door roller on motor shaft 15, roller shutter
In the normal lifting process of door, door roller rotating speed is relatively low, and brake disk rotating speed is relatively low, and anti-fall bow arm 7 closes under the action of tension spring 9
Hold together, be arranged at this time it is anti-fall bow arm 7 on ratchet A10 and brake base 2 on ratchet B13 there are gaps, do not play braking action；
When the unexpected quickly tenesmus of rolling screen door, 1 high speed rotation of brake disc, anti-fall bow arm 7 under the influence of centrifugal force, overcomes tension spring 9
Pulling force is thrown away outward, and the ratchet B13 that ratchet A10 and brake base 2 on anti-fall bow arm 7 are arranged at this time mutually tightly engages production
Raw brake force, prevents door roller from rotating, to prevent rolling screen door from quickly dropping.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.Therefore, of the invention
Protection domain should be determined by the scope of protection defined in the claims.
