Description

Hollow shutter

Technical Field

The invention belongs to the technical field of built-in sun-shading hollow glass products, and particularly relates to a blind window.

Background

Hollow blinds are popular in the market because of their good thermal and acoustic insulation properties. In the prior art, the control mechanism is usually arranged at the left side edge part or the right side edge part of the window glass along the height direction of the shutter window. The arrangement mode is mainly that the size of the window in the height direction is obviously larger than that of the window in the length direction, and the vertical arrangement mode can enable the stroke range of the upward or downward movement of the control mechanism to be enough to meet the requirement of driving the integral lifting or descending of the blind.

The above-mentioned control mechanism means a device which is realized by a blind turnover control mechanism, a blind lifting control mechanism and a manual operation control mechanism and can control the lifting of the blind and the turnover of the blind.

However, the existing hollow blinds may in some cases present the following situations:

the height of the window is relatively small while the length of the window is relatively large, i.e. the dimension in the length direction of the window is significantly larger than the dimension in the height direction of the window. If the control mechanism is vertically arranged at the left side edge part or the right side edge part of the window body, the moving stroke of the control mechanism is limited due to the limitation of the structural size of the window body, and the requirement of the stroke range for driving the integral lifting or descending of the blind cannot be met.

Advantageous effects

The control mechanism is arranged at the top of the hollow shutter, so that the control mechanism can horizontally and transversely move at the top of the hollow shutter, and the lifting and turning of the shutter can be regulated and controlled. The inner manipulator is matched with the corner device and the lifting and overturning transmission device which are arranged at the top of the shutter, so that the transmission parts of the shutter can be concentrated at the top of the window body, and the transmission device is not required to be arranged at the bottom of the hollow shutter. Therefore, the invention can directly arrange only a thin frame at the bottom of the hollow shutter, thereby enlarging the light transmission area of the hollow shutter. The guide rail of the external controller which is arranged at the top of the hollow shutter and is used for being manually operated by a user can be specifically arranged above the handle, and the opening of the guide rail faces downwards according to the transmission relation of the manual external controller. Therefore, the track of the manual outer manipulator is arranged at the top of the window body, and the opening of the guide rail faces downwards, so that dust accumulation in the opening of the track is avoided, and the handle can be kept to slide smoothly in the track.

The invention redesigns the lifting component and the overturning component of the hollow built-in shutter, and changes the transmission relationship between the shutter internal controller and the component for controlling the lifting and overturning of the shutter. The invention can control the lifting and turning of the blind by the transverse movement of the handle through the inner manipulator transversely and horizontally moving at the top of the hollow blind by arranging the transmission mechanisms which are not interfered with each other in parallel in the same component. The invention can place the control mechanism in the frame at the top of the window body. Therefore, the present invention can improve the height restriction of the blind when the elevation and the turnover of the blind are controlled in the lateral direction.

Furthermore, by turning the lifting assembly and the turning assembly of the invention by 90 degrees, the invention can further change the operation mode of the manipulator in the top frame of the window body from horizontal and transverse to longitudinal to control the lifting and turning of the blind. Because the transmission of the lifting traction rope and the overturning traction rope does not depend on gravity, the conversion only needs to place the control handle in the side frame. Therefore, the control system has high flexibility and can be suitable for different application scenes.

The lifting rope wheel and the overturning rope wheel are arranged side by utilizing the corner device, the overturning slide block for fixing the overturning rope is arranged outside the transmission pulley in a sliding manner by utilizing the lifting overturning transmission device, and the lifting traction rope is supported by utilizing the rotating pulley. Therefore, in the process that the inner manipulator moves left and right, when the resistance of the inner manipulator to the overturning hauling rope does not exceed the damping range of the friction control piece, the overturning hauling rope is fixed by limiting the rotation of the overturning hauling rope fixing roller through damping, the overturning hauling rope horizontally rotates along the front and back direction to drive the overturning ladder rope to move, and the louver curtain overturning is realized by utilizing the relative displacement of the front side and the back side of the overturning ladder rope; and when the resistance of the inner manipulator to the overturning hauling rope exceeds the damping range of the friction control piece, the lifting hauling rope is pulled upwards or descended through the left and right movement of the inner manipulator, so that the lifting of the blind is controlled.

Additional features and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.
