Description

The present invention claims the priority of the Chinese patent application filed on May 25, 2009 by the Chinese Patent Office, the application number is 200920157571.0, and the invention is entitled "a two-track louver curtain", the entire contents thereof This is incorporated herein by reference. Technical field

Field of the Invention This invention relates to the field of blinds, mobile grilles or other safety shut-off devices, and more particularly to a two-track louver blind. Background technique

The venetian blind is a common door and curtain structure. The biggest feature is that each blade can rotate around the axis to adjust the angle of entering the light, so that the natural light in the room is varied. The existing venetian blinds are available in both non-moving and mobile versions: each of the former blades can rotate around its axis of rotation but cannot slide, which makes the fences fill the entire door and window, which not only affects the line of sight, but also reduces the maximum penetration. The amount of curtain light, thereby limiting its range of use; the latter's blades are both rotatable and slidable, and have become mainstream products in the market due to better overcoming the drawbacks of non-mobile louver blinds.

At present, the mobile louver curtain has several main forms such as a multi-track structure, a single-track structure, and a double-track structure, which are respectively reviewed below.

One of them is a multi-track structure. Each blade is installed in a track groove and can slide along the corresponding track groove, and all the blades are stacked when moving to one side; since the adjacent two blades are fixed on the connected sliding block group, the sliding box body is hooked to the blade There is no relative rotation, so that the blade cannot rotate when sliding. Since each blade must be individually equipped with a track groove, the installation space is increased and the production cost is increased.

The second is a monorail structure. A plurality of blade sets are mounted in a track, and the blades are slid in the track by a plurality of pulleys, which can drive the finite width blades to open and close; because the rotating shaft is mounted on the blades, the blade turning angle can be adjusted through the rotating shaft. The problem is that the steering angle of the blade needs to be adjusted with the shaft and the blade width is greatly limited. If the blade width is wider, for example, more than 15 cm, the blade will not meet the assembly requirements, which limits the application of the louver.

The third is a two-track structure. The blades are staggered on the two rails by a joint sliding block so that each blade can rotate while sliding. The defect is that the structure of the connected sliding box group is more complicated. The production cost is increased; at the same time, the blade angle cannot be adjusted after the venetian blind is fully opened, so that the shading effect can only be adjusted and the light transmission effect cannot be adjusted, so that the application of the venetian blind is greatly restricted. Summary of the invention

In view of the above, the present invention provides a two-track louver curtain, each of which is slidable and rotatable, and the louver curtain can be adjusted to fully adjust the blade angle. The structure is simple and can be applied to blades of a relatively large width.

In order to solve the above technical problem, the louver according to the present invention has the technical proposal that: the louver curtain comprises a plurality of blade assemblies and two rails, the blade assembly comprises blades; each blade assembly connects two sliding box assemblies, Two slide box assemblies are respectively mounted on one track; two of the slide box assemblies are rotatable relative to the blades, and at least one of the slide box assemblies is slidable relative to the blades.

Preferably, a transmission belt is provided in series with all the sliding box assemblies; when the driving belt rotates, the two sliding box assemblies are driven to slide in opposite directions along the rail.

Preferably, the belt is a bead chain; the end of the rail is provided with a bead chain supporting the bead chain.

Preferably, each track is provided with a sliding slot; the sliding box assembly comprises a sliding box body and a sliding box guiding wheel, and the sliding box guiding wheel is installed in the sliding slot to support the sliding box body.

Preferably, each of the sliding box assemblies includes a sliding box side wheel mounted on the sliding box body, and the sliding box side wheels are rotatable along a side wall of the sliding slot.

Preferably, the two rails are connected double rails, and the front cap and the rear end are respectively mounted with a front cap assembly and a rear cap assembly to prevent the sliding box assembly from slipping out.

Preferably, each of the blade assemblies comprises:

a movable tab and a blade mounted on the movable tab;

Two activity hooks, one of which is fixed to the movable tab and the other is slidably coupled to the movable tab.

Preferably, each of said blade assemblies includes a blade screw that secures the blade to said movable tab.

Preferably, a blade handling device is provided, the blade handling device being closest to the end of the track The position of the slide box assembly is connected to control the sliding and/or rotation of the blade.

Compared with the prior art, the present invention drives the blades to slide in the track through a plurality of sliding box assemblies to realize the opening or closing of the blades; meanwhile, the staggered sliding of the sliding box assembly in the track can drive the blades to rotate, so that the blades are rotated. The steering angle is consistent; this enables the blade angle to be adjusted after the venetian blind is fully opened, that is, the shading effect and the light transmission effect can be conveniently adjusted; since the sliding box group can slide relative to the blade, the assembly requirement of the larger width blade can be satisfied. In the present invention, the single-slider assembly is relatively easy to design and does not require accessories such as a blade shaft; this not only facilitates simplification of the structure, but also contributes to a reduction in production cost.
