Attached drawing to be used is briefly described.Obviously, described attached drawing is a part of the embodiment of the utility model, rather than complete
Portion's embodiment, those skilled in the art without creative efforts, can also be obtained according to these attached drawings it
His design scheme and attached drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The technique effect of the design of the utility model, concrete structure and generation is carried out below with reference to embodiment and attached drawing
It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field
The other embodiment that art personnel are obtained without creative efforts belongs to the model of the utility model protection
It encloses.In addition, all connection/connection relations being previously mentioned in text, not singly refer to component and directly connect, and referring to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, to form more preferably coupling structure.
Referring to Fig.1, wooden louvres brake system comprising head seat 1, sprocket wheel 2, planetary gear deceleration device, driven pivoted arm 6,
Unilateral bearing 9, metal axle sleeve 10, torsional spring 7 and spring base 8, the planetary gear deceleration device include main body 3, several planetary gears 4
With planetary wheel carrier 5, the unilateral bearing 9 is sleeved on metal axle sleeve 10, and the metal axle sleeve 10 is sleeved on the axis of driven pivoted arm 6
On body, the rear portion of the planetary wheel carrier 5 is provided with the first protrusion 50, and the front of the driven pivoted arm 6 is provided with the second protrusion 60,
The first installation gap is formed between first protrusion 50 and the second protrusion 60, the torsional spring 7 is sleeved on the outer surface of unilateral bearing 9
Afterwards, two straight-arms of torsional spring 7 are mounted in the first installation gap.Certainly, the utility model further includes the accessories such as bead 11.
It is further used as preferred embodiment, the metal axle sleeve 10 is mounted on driven pivoted arm 6 by trip bolt
On axis body.
It is further used as preferred embodiment, the reduction ratio of the planetary gear deceleration device is 1:6.
It is further used as preferred embodiment, the quantity of the planetary gear 4 is 3, and 3 planetary gears 4 are distributed on planet
On wheel carrier 5.
It is further used as preferred embodiment, first protrusion 50 and the second protrusion 60 are arc convex.
It is further used as preferred embodiment, the hexagonal hole for connection is disposed on the axis body of the driven pivoted arm 6.
Mandrel of the metal axle sleeve 10 as unilateral bearing 9 forms the operative minor of unilateral bearing 9, utilizes the original of unilateral bearing 9
Reason realizes the brake system of the larger torque of this system, while covering a upper torsional spring 7 in the outside of one-way shaft, organizes COST system
Complete brake system.First protrusion 50 of planetary wheel carrier 5 acts on two straight-arms of torsional spring 7, towards unlocking direction on act on, can
It is rotated with left and right push the spring, and the second protrusion 60 of driven pivoted arm 6 acts on two straight-arms of torsional spring 7, towards the side of locking
To, the rotation of driven pivoted arm 6 is unable to the rotation of driving spring, to be connect with six square shafts by the hexagonal hole on driven pivoted arm 6,
The winder of locking or drive system, and realize the lifting or stopping of wooden louvres blade.
The utility model passes through 1:6 planetary gear deceleration device slows down, and completes labor-saving effect, makes heavy wooden louvres
Lifting becomes light, unilateral bearing 9, rectangular locked towards one, can the larger torque of load-bearing, and another it is rectangular then can be with
Free movement, almost non-resistance, passes through pulling bead 11, band movable sprocket 2, startup planetary gear deceleration device, to drive planet
Wheel carrier 5, and planetary wheel carrier 5 is rotated to unlocking direction pushing button, being further driven to driven pivoted arm 6 rotates, at this time unilateral bearing 9
It in locking state, cannot rotate, realize the rising of blind, once it stops operating, in the feelings of wooden louvres blade dead weight
Under condition, driving brake system in opposite direction, at this time unilateral bearing 9 be operated on the direction of locking, generate high torque, will
Wooden louvres blade is located in some height；If we think that opposite direction pulls bead 11, band movable sprocket 2 to drive planet
Deceleration device is taken turns, to drive planetary wheel carrier 5, and planetary wheel carrier 5 pushes torsional spring 7 to rotate to unlocking direction, at this time unilateral bearing 9
It is operated in unlocked state, driven pivoted arm 6 is easily driven to rotate, the blade of wooden louvres system is begun to decline, and once stops exerting oneself,
In the case of wooden louvres blade dead weight, driving brake system in opposite direction, at this time unilateral bearing 9 be operated in locking
Direction on, generate high torque, the blade of blind is located in some height.
It is to be illustrated to the better embodiment of the utility model, but the invention is not limited to institute above
Embodiment is stated, those skilled in the art can also make various be equal without departing from the spirit of the present invention
Modification or replacement, these equivalent modifications or replacement are all contained in the application claim limited range.
