Description

Blind control device and hollow glass built-in shutter

Technical Field

The invention relates to the field of hollow shutters, in particular to a shutter control device and a hollow glass built-in shutter.

Background

Hollow blinds are preferred in the market for their good thermal and acoustic insulation properties, but in case of failure of the operating mechanism of the blind inside the hollow sealed structure, the glazing can only be opened for repair by destructive means. Due to the high maintenance costs, high demands are made on the reliability of the blind actuation mechanism inside the hollow blind.

The louver curtain commonly used in the prior art mainly drives the louver blades to rotate through rope connection, and the light transmission or shading effect is realized through the oblique rotation of the blades by a certain angle. The common curtain sheet turning process of the existing hollow shutter is as follows: the outer manipulator is magnetically attracted with the inner manipulator which is positioned between the front glass and the rear glass and is in sliding fit with the longitudinal frame strip cavity, when a user stirs the outer manipulator, the user drives the inner manipulator, the inner manipulator drives the curtain sheet overturning traction rope, the curtain sheet overturning traction rope drives the overturning wheel, the overturning wheel drives the curtain sheet overturning shaft which is fixedly inserted with the curtain sheet overturning shaft, the curtain sheet overturning shaft drives the overturning device which is fixedly inserted with the curtain sheet overturning shaft, and because the two ends of the overturning device are rotatably supported on the overturning device fixing seat arranged on the upper transverse frame strip and the upper end of the ladder rope of the venetian blind is fixed with the overturning device, when the curtain sheet overturning shaft rotates clockwise or anticlockwise by a required angle, the overturning device drives the overturning device to correspondingly rotate by the required angle, so that the curtain sheet overturns inwards or outwards by the ladder rope. The curtain sheet overturning shaft and the overturning wheel in the prior art are connected in a mode that the curtain sheet overturning shaft and the overturning wheel penetrate through a corner seat or a traction rope transition guide device and then are fixedly inserted into the overturning wheel facing one side of the longitudinal frame strip, so that the other end of the curtain sheet overturning shaft is in a suspended state, abnormal vibration can be inevitably generated in the action process of the curtain sheet overturning and traction rope, the overturning wheel and the vibration of the curtain sheet overturning shaft can influence the overall rotating stability of the curtain sheet overturning shaft, the rotation of the turner can not be synchronous with the curtain sheet overturning shaft in serious conditions, and finally the effect of the curtain sheet overturning driven by the ladder rope is influenced. In addition, the turner forms a limiting block, and the limiting block is matched with the limiting foot to play a role in limiting the clockwise or anticlockwise rotation of the turner. This kind makes turner stall by the stopper to make curtain piece trip shaft stop, the structural design that the turnover wheel is also in the stall state simultaneously says from the theory and considers from conventional technical angle and does not have technical problem, and in case the stopper suffers the hindrance of spacing foot, the turnover rope is curtain piece upset haulage rope promptly and can not drive the turnover wheel, but can expose following two kinds of defects in the in-service use process: firstly, the limit block extending on the turner has impact condition at the moment of contacting with the limit foot, which is unfavorable corresponding to the stable motion of the ladder rope driven by the turner, and the limit block can be damaged by collision; secondly, even the turner is in the not rotatable state, if continue to drag the curtain piece upset haulage rope, then also be in quiescent condition because of the upset wheel, the damage can appear and even cracked condition to the race of upset wheel promptly the grooving also can suffer contusion of different degrees.

The lifting of the blind commonly used in the prior art is realized by winding and unwinding a lifting traction rope of the blind, one end of the lifting traction rope of the blind is fixed with a bottom strip of the blind, and the other end of the lifting traction rope of the blind sequentially passes through a traction rope hole on a curtain sheet, a rope hole on an upper cross frame strip and a rope hole on a fixed seat of a turner from bottom to top, then continuously passes through a traction rope transition guide seat and a lifting traction rope transition wheel arranged in the traction rope transition guide seat, then is downwards wound on a sliding wheel on an inner manipulator for subsequent operation, and then is upwards returned to the traction rope transition guide seat and is fixed with the traction rope transition guide seat. The above-mentioned lifting traction rope transition wheel is made of a cylindrical body with a very small diameter, and is supported on the wall body of the traction rope transition guide seat by means of a fixed pin, so that the transition wheel is not freely rotated, resulting in troublesome operation and also reducing the service life of the blind lifting traction rope.

In view of the foregoing, there is a need for reasonable improvements, and the solutions described below are made in this context.
