Abstract
The utility model discloses a Roman curtain brake controller which comprises a shaft core rotationally arranged in a cylindrical shell. A guide groove is formed around the surface of the shaft core; a square-hole channel is arranged on the groove in an inclined way; a positioning groove is axially formed on the inner wall of the cylindrical shell; a ball is arranged on the positioning groove; and the ball is also matched with the guide groove. As the curved guide groove and the square-hole channel are arranged on the shaft core, the ball can move in the guide groove and can be stopped in the square-hole channel. When the rotating Roman curtain brake controller is required to be stopped, the shaft core can rotate in negative direction for less than half turn and then rotate in positive direction to ensure that the ball gets to a blind end of the square-hole channel, and then the self-locking function can be realized; and if the shaft core requiring rotating in positive direction continuously, the shaft core is required to rotate in negative direction for less than half turn to ensure that the ball gets into the guide groove again, and then the controller can continuously slide downward. The controller has the advantage of simple structure, is convenient to operate, operates flexibly, and has low cost and wide applicable scope.
Description
Technical field
The utility model relates to a kind of system head controller, particularly a kind of roman shade brake monitor.
Background technology
Chinese patent literature CN201507228U discloses a kind of curtain system brake system on June 16th, 2010, comprise the system head main body, mandrel is extended at described system head main body middle part, described mandrel is set with metal axle sleeve outward, outside metal axle sleeve, be set with torsion spring, have the actuator movable set outside torsion spring, torsion spring to be locked and release.This complex structure, stuck phenomenon appears in cost height easily, causes the curtain can not lifting.
The utility model content
The purpose of this utility model aim to provide a kind of simple and reasonable, easy and simple to handle, operation is smooth and easy, also can realize stopping or the roman shade brake monitor of the function of self-locking, to overcome weak point of the prior art.
By a kind of roman shade brake monitor of this purpose design, comprise and rotate the axle core that is arranged in the cylinder cover, its architectural feature is that a wicking surface is surrounded with direction recess, groove tilts and is provided with back-shaped ditch; The cylinder cover inwall axially is provided with locating slot, and locating slot is provided with ball, and ball also cooperates with direction recess.
Described direction recess is provided with one or more, is the curved shape that height rises and falls; At least be provided with a back-shaped ditch on every direction recess, back-shaped ditch is provided with a cecum and more than one openend, and openend is communicated with the direction recess of one or more.
Described axle core center is provided with the power transmission shaft core, and stretch out outside the cylinder cover at power transmission shaft core two ends, and be connected with driving mechanism with shade rollerl blind shaft respectively.Described axle core is the cover tubular, and the center is provided with the power transmission shaft core; Be connected with reinforcing rib between power transmission shaft outer core and the axle in-core wall.
Described cylinder cover open-top, an end of bottom respective shaft core power transmission shaft core is provided with trepanning; Cylinder cover opens wide the place and also is provided with end cap, and the other end of the corresponding power transmission shaft core of end cap is provided with centre bore.Described end cap is connected, is threaded or ultrasonic bonding by buckle with cylinder cover.
Described driving mechanism is rope/pelletron driving mechanism, perhaps motor-driven mechanism.
Designed crooked direction recess and back-shaped ditch on the axle core of the present utility model, ball can move in direction recess and stop at back-shaped ditch place.When the roman shade brake monitor can just change the cecum that makes ball enter into back-shaped ditch to axle core counter-rotating small semicircle again when rotation needs to stop, just can realize self-locking; If think to allow again its continue just to change, must allow its small semicircle that reverses again make ball from newly entering the direction recess, controller just continues toward lower slider.It is simple and reasonable, easy and simple to handle, operation is smooth and easy, cost is low, applied widely.
