Shutter built in hollow glass

Abstract

The invention discloses a shutter built in hollow glass. The shutter comprises a frame body with a shutter blind cavity in the middle, a shutter blind arranged in the shutter blind cavity of the framebody and a lifting control mechanism used for driving the shutter blind to ascend and descend; the shutter blind comprises a plurality of blades and a traction rope for driving the blades to lift; the lifting control mechanism comprises a traction rope roller and a drawing follower which are correspondingly arranged on the frame body; the drawing follower comprises a base and a balancing weight,a magnetic attraction structure is arranged on the lower portion of the base in the height direction, the balancing weight is arranged on the base, and the balancing weight is located above the magnetic attraction structure in the height direction of the base; the base is further provided with a traction rope connecting structure; and one end of the traction rope bypasses the traction rope rollerto be connected with the traction rope connecting structure. The shutter has the characteristics of good stability, convenience in operation and wide application range. Furthermore, the shutter has abetter limiting effect, and the situation that the traction rope is wound can be avoided.

Description

technical field [0001] The invention relates to the technical field of sunshade hollow glass products, in particular to a hollow glass built-in shutter. Background technique [0002] The built-in shutters of insulating glass refer to the shutters that can be raised and lowered as needed in two pieces of glass (inner glass and outer glass, also known as front glass and rear glass) that are arranged in a face-to-face state and seal the surrounding edges. The windows that belong to the category of sunshade hollow glass products are composed of curtains. There are two types of control for hollow glass built-in blinds: one is single handle control; the other is double handle control. Raising and lowering of venetian blinds. Double-handle control means that two inner manipulators and two outer manipulators respectively control the flipping of the venetian blinds and the lifting of the venetian blinds. [0003] In the prior art, the lifting of the venetian blind is controlled by...

Problems solved by technology

Since the counterweight is added under the magnetic iron traction inner slider, it not only saves lifting effort, but also can open the large size and heavy weight without increasing the number of original magnetic iron pieces or increasing the volume of the magnetic iron. However, the inner manipulator of this structure still has the following problems: the counterweight is set under the magnetic iron traction inner slider, and this design has the disadvantage of being easy to shake and resulting in poor stability; in addition, the counterweight is in the Under the magnetic iron traction inner slider, the magnetic iron traction inner slider cannot be pulled down to the bottom of the blinds. Since the outer manipulator needs to be used in conjunction with the magnetic iron traction inner slider, the placement position of the outer manipulator on the inner glass Higher, when the installation position of the blinds is too high, taller users are required to operate the external controller, which limits the use of shorter users, especially not suitable for children, and has the disadvantages of troublesome operation and narrow application range ; In addition, the traction rope of the inner manipulator of this structure is easy to be entangled
