Description

An internal control limiting device for a hollow louver Technical Field

[0001] This utility model belongs to the field of hollow louver technology, specifically relating to an internal control limiting device for hollow louvers. Background Technology

[0002] Manually operated hollow venetian blinds are a common window structure, mainly consisting of a window frame, outer glass, inner glass, blinds, inner controller, outer controller, and internal wiring harness. The inner and outer controllers are magnetically connected. As is well known, the outer controller is placed on the surface of the inner glass and protrudes from it, connecting to the inner controller. During transportation, to facilitate stacking and ensure safety, the outer controller is often removed beforehand and reinstalled upon arrival. However, in actual transport, it has been found that the inner controller, without the control of the outer controller, bounces within the window frame with the bumps of the transport vehicle. This not only impacts the window frame, causing deformation, but also may entangle the wiring harness. Since the inner controller is inside the window frame, it cannot be controlled when the outer and inner glass are closed and sealed. Therefore, the industry urgently needs a structure that can limit the movement of the inner controller while effectively preventing it from hindering its movement.

[0003] In view of the above, it is necessary to design an internal controller limiting device for a hollow louver that is simple in structure, low in cost, and capable of fixing the internal controller when it is detached from the control of the external controller. To this end, the applicant has made a beneficial design, and the technical solution described below arose from this background. Summary of the Invention

[0004] The purpose of this invention is to provide an inner control limiting device for hollow louvers, which helps to improve the limiting device so that the inner control can be fixed and limited within the window frame, and the sliding of the inner control can be unaffected after it is released from the limit. This is beneficial to improving transportation efficiency and avoiding louver malfunctions caused by bumps.

[0005] The present invention accomplishes its objective as follows: An internal control limiting device for a hollow venetian blind includes a window frame, a venetian blind that moves vertically within the window frame, an inner glass panel attached to the front side of the window frame, an outer glass panel attached to the rear side of the window frame, and an internal control unit located within the window frame and on one side of the venetian blind. The internal control unit is connected to the venetian blind via a pair of lifting ropes. The key feature is that the side of the internal control unit closest to the window frame has a hook, and a limiting mechanism is installed on the window frame corresponding to the hook position. The hook can be detachably hooked onto the limiting mechanism. The limiting mechanism includes an anti-hooking slider to prevent the hook from re-hooking onto the limiting mechanism after detachment.

A left warm frame is fixedly fastened to the inner part of the left frame strip by a snap fastener. A right warm frame is fixedly fastened to the inner part of the right frame strip by a snap fastener. The Venetian blind is positioned between the left and right warm frame frames. A pair of flip seats are provided inside the warm frame. The flip seats are connected by a rotating shaft. The Venetian blind is driven to flip by a pair of ladder ropes connected to the corresponding flip seats. The inner controller and the limiting mechanism are located inside the left or right warm frame. The upper end of the inner controller forms an inner control lifting rope wheel. A lifting guide wheel is provided on an upper corner piece above the inner controller. One end of the lifting rope is connected to the Venetian blind, and the other end passes through the flip seat, the lifting guide wheel and the inner control lifting rope wheel in sequence before being fixed upward to the corresponding upper corner piece.

[0007] In another specific embodiment of this utility model, an inner control roller is provided at the upper and lower ends of the inner control on the side facing the inner glass, and a set of magnets is fixed along the length direction at the position between the two inner control rollers on the side facing the inner glass.

[0008] In another specific embodiment of this utility model, the hook has a hook seat, and the upper end of the hook seat has a pair of hook feet that are snapped together with the internal controller.

[0009] In another specific embodiment of this utility model, the limiting mechanism further includes a limiting seat, which is fixedly installed on the window frame by fasteners. A sliding cavity is formed in the middle of the limiting seat and on the side close to the window frame. A latch is formed in the middle of the limiting seat and on the side facing the hook, which communicates with the sliding cavity. The anti-hook slider is disposed in the sliding cavity and can slide up and down. One end of the anti-hook slider protrudes from the latch and forms an anti-hook slider boss. An anti-hook slider inclined surface is formed on the upper and lower sides of the boss. A hook guide inclined surface is formed on the hook that cooperates with the anti-hook slider inclined surface.

[0010] In another specific embodiment of this utility model, a slide cavity guide bar is formed on each of the two side walls of the slide cavity along the length direction, and an anti-hooking slider guide groove is formed on each side of the anti-hooking slider to cooperate with the slide cavity guide bar.

[0011] The present invention, by adopting the above-mentioned structure, has the following advantages: First, because a limiting mechanism is set inside the window frame and a hook is set on the inner controller, the inner controller can be effectively fixed during the transportation of the louver, thereby avoiding malfunction of the inner controller caused by transportation bumps; Second, because an anti-hook slider is adopted to guide the hook out and prevent the hook from hooking into the limiting mechanism again, workers can quickly make the inner controller contact the limiting mechanism from the outside and prevent the limiting mechanism from obstructing the movement of the inner controller.
