Description

Technical Field

[0001] The invention relates to the technical field of sunshade hollow glass products, and in particular to a hollow glass built-in blind. Background Art

[0002] Insulating glass built-in blinds refer to windows that are set in a face-to-face state and sealed on all sides. They are made of two glasses (inner glass and outer glass, also called front glass and rear glass) that are sealed on all sides and have blinds that can be raised and lowered as needed. They belong to the category of sunshade insulating glass products. There are two types of control methods for insulating glass built-in blinds: one is single-handle control; the other is double-handle control. Single-handle control means that the blinds are turned over and raised and lowered by the cooperation of an external controller and an internal controller. Double-handle control means that the blinds are turned over and raised and lowered by two internal controllers and two external controllers respectively.

[0003] In the prior art, the lifting of the venetian blind is controlled by an inner controller and an outer controller, wherein the inner controller includes a magnetic iron traction inner slider, the upper end of which is connected to a traction rope, and a counterweight is fixed to the lower end of the magnetic iron traction inner slider. Since a counterweight block is added below the inner slider pulled by the magnetic iron, not only is lifting less labor-intensive, but large-sized and heavy venetian blinds with large size and heavy weight can be opened without increasing the number of original magnetic iron blocks or increasing the volume of the magnetic iron. However, the inner operator of this structure still has the following problems: the counterweight block is arranged below the inner slider pulled by the magnetic iron, and such a design has the disadvantage of easy shaking and poor stability. In addition, the counterweight block is below the inner slider pulled by the magnetic iron, so that the inner slider pulled by the magnetic iron cannot be pulled down to the bottom of the blind. Since the outer operator needs to be used in conjunction with the inner slider pulled by the magnetic iron, the outer operator is placed at a higher position on the inner glass. When the installation position of the blind is too high, a user with a taller height is required to operate the outer operator, which limits the use of users with a shorter height, especially it is not suitable for children, and has the disadvantages of inconvenient operation and a narrow scope of application. In addition, the traction rope of the inner operator of this structure is easy to be entangled. Summary of the invention

During use, when the operator, i.e., the user, moves the aforementioned external retracting operator upward or downward, since the external retracting operator and the retracting follower are magnetically attracted together, when the external retracting operator moves upward or downward, it drives the retracting follower to move upward or downward accordingly, so that the traction rope is retracted or released. Specifically, the traction rope is retracted, and the blind is raised upward. At this time, the base of the retracting follower is in a low position, so that the magnetic structure can be pulled down to the bottom of the blind. On the contrary, when the blind in the rising state is to be lowered (also called closed), then just move the external retracting operator upward. At this time, because the bottom strip of the blind is at the bottom, that is, in the groove with the privacy frame, and the retracting follower is at the top, the top of the retracting follower contacts the limiter.
