Description

Hollow glass built-in shutter

Technical Field

The invention relates to the technical field of sun-shading hollow glass products, in particular to a hollow glass built-in shutter.

Background

A hollow glass built-in blind is a window belonging to the field of a hollow glass product for sunshade, which is configured by arranging blinds capable of being lifted as required in two pieces of glass (inner glass and outer glass, which may be referred to as front glass and rear glass) which are arranged in a state of facing each other and which close the peripheral edge portions. The hollow glass built-in shutter has two control modes: one is single handle operation; the second mode is double-handle control, and the single-handle control means that the turnover of the blind pieces of the blind and the lifting of the blind are realized by the cooperation of an outer controller and an inner controller. The double-handle control means that two inner manipulators and two outer manipulators respectively control the turnover of the blind pieces of the blind and the lifting of the blind.

In the prior art, the lifting of the blind is controlled by an inner manipulator and an outer manipulator, wherein the inner manipulator comprises a magnetic iron traction inner sliding block, the upper end part of the inner manipulator is connected with a traction rope, and the lower end of the magnetic iron traction inner sliding block is fixedly provided with a balancing weight. After the balancing weight is additionally arranged below the magnetic iron traction inner sliding block, labor is saved, and a large-size shutter curtain with large size and heavy weight can be opened on the premise of not increasing the number of blocks of the original magnetic iron or increasing the volume of the magnetic iron; however, the inner manipulator of this structure has the following problems: the counterweight block is arranged below the magnetic iron traction inner sliding block, so that the design has the defect of poor stability caused by easy shaking; in addition, the counterweight block is arranged below the magnetic iron traction inner sliding block, so that the magnetic iron traction inner sliding block cannot be pulled down to the bottom of the shutter, the outer manipulator needs to be matched with the magnetic iron traction inner sliding block for use, the placement position of the outer manipulator on the inner glass is higher, when the installation position of the shutter is too high, a user with a higher height is required to operate the outer manipulator, the use of a user with a shorter height is limited, and the counterweight block is particularly not suitable for children to use and has the defects of troublesome operation and narrow application range; in addition, the traction rope of the inner manipulator with the structure is easy to wind.
