Description

TECHNICAL FIELD

[0001] The utility model relates to hollow glass built-in shutter technical field especially relates to a three glass two cavity shutter slide control subassembly with relay magnet. BACKGROUND

[0002] Hollow glass built-in shutter as a kind of building energy-saving product, by integrating the louver curtain in the glass cavity, it has the functions of shading and heat preservation. Among them, three glass two cavity structure can effectively reduce the heat exchange between louver and outdoor environment due to the addition of outdoor independent cavity, and the energy-saving advantage is remarkable. In the prior art, louver control mainly adopts magnetic coupling transmission mechanism, that is, the magnetic force coupling is formed between the handle magnet arranged on the outer side of glass and the driving magnet of internal louver controller, to realize non-contact transmission. However, the structure has the following technical bottlenecks:

[0003] Firstly, the traditional transmission mechanism needs to ensure that the handle magnet, the intermediate transmission magnet and the internal controller magnet are synchronously coupled between the multiple layers of glass. Affected by the glass layer spacing tolerance (±0.5mm) and the magnetic assembly precision, the multi-stage magnet is difficult to keep the spacing constant in the whole stroke movement. Especially in the application of temperature difference deformation or large size glass (>3m 2 ), the magnet spacing is easy to deviate by millimeter, which causes the magnetic attraction to drop sharply and causes the magnet to fall off. After the magnet falls off, it needs to be reset by disassembling the whole window, which has high maintenance cost.

[0004] Secondly, the existing magnetic transmission assembly mostly adopts rigid connection structure, which cannot compensate the relative displacement caused by the glass flexural deformation. When the window body is affected by wind load or installation stress, the misplacement probability of magnet is significantly increased, which causes transmission failure. Statistical data shows that the annual average failure rate of traditional structure in high-rise building application is more than 12%. In addition, the lifting rope of internal controller is easy to be tangled and disordered in repeated winding, which further increases the risk of transmission mechanism jamming.

[0005] For the above problems, although there are improvement schemes to try to optimize the magnet arrangement or add auxiliary positioning parts, but they all do not break through the inherent design logic of multi-stage magnet linkage transmission, and cannot fundamentally solve the core defects of poor magnet stability and difficult reset. Therefore, it is urgent to develop a new type of transmission mechanism which has self-adaptability, can maintain the stability of magnetic force transmission and is easy to maintain UTILITY MODEL CONTENTS

[0006] The technical object of the utility model is to provide a three glass two cavity shutter slide control subassembly with relay magnet, to solve the problems of magnet spacing instability, falling reset difficulty and rope winding risk caused by multi-stage magnet linkage tolerance accumulation in traditional hollow glass built-in shutter.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] A sliding control assembly for a triple-glazed, two-cavity louvered blind with a relay magnet, comprising:

[0031] External control slider 1, such as Figure 1 As shown: An external magnetic groove 101 with a built-in magnet is provided in the center of the glass adsorption surface, and pulleys are installed in the symmetrically arranged external pulley grooves 102. The external slider 1 is located on the outside of the window and serves as a handle for controlling the raising, lowering, and rotating of the blinds.

[0032] Internal control slider assembly, such as Figure 2 As shown: It consists of an inner control slide frame 2 and an internal control slider 3. The adsorption surface of the internal control slider 3 is provided with an inner control magnetic groove 301 and an inner control pulley groove 302 that are symmetrically arranged on the upper and lower sides. A magnet is installed in the inner control magnetic groove 301 and a pulley is installed in the inner control pulley groove 302. An inner control limit block 4 is provided at the top of the inner control slide frame 2 to restrict the upward movement of the inner control slider 3.

[0033] like Figures 3-5 As shown: The relay sliding assembly includes a relay slide frame 5, a first relay slider 6, and a second relay slider 7. The first relay slider 6 is attracted to the external control slider 1; the second relay slider 7 is attracted to the internal control slider 3.

[0034] The first relay slider 6 and the external control slider 1 have a first relay magnetic groove 601 and a first relay pulley groove 602 symmetrically arranged on their adsorption surfaces. The second relay slider 7 and the internal control slider 3 have a second relay magnetic groove 701 and a second relay pulley groove 702 arranged on their adsorption surfaces. Magnets are installed in both the first relay magnetic groove 601 and the second relay magnetic groove 701; pulleys are installed in both the first relay pulley groove 602 and the second relay pulley groove 702.

[0035] The top and bottom surfaces of the first and second relay sliders are respectively provided with docking grooves 603 and 703.

[0036] Two sliders are inserted into the docking slots 603 and 703 through the waist-shaped connecting piece 8 and fixed by the positioning pin 9. The relay slide frame 5 is provided with a guide slide 501 along its length direction. The front and back of the first relay slider 6 are symmetrically provided with a first guide slide rail 604. The front and back of the second relay slider 7 are symmetrically provided with a second guide slide rail 704. The first guide slide rail 604 and the second guide slide rail 704 are both placed in the guide slide 501, and the guide slide 501 and the two guide slide rails 604 and 704 form a sliding pair.

[0037] The length of the waist-shaped hole of the waist-shaped hole connecting piece 8 is greater than the minimum distance between the positioning pins at both ends, so that the two intermediate sliders can be finely adjusted in both directions along the glass plane; the guide slide 501 and the guide slide rails 604 and 704 adopt a clearance fit to ensure the accuracy of linear motion.

[0038] like Figure 6 As shown, the working principle is as follows:

[0039] When the external control slider 1 moves along the outer surface of the glass:

[0040] Hierarchical magnetic force transmission: The external control slider 1 attracts and drives the first relay slider 6, and the second relay magnet 7 simultaneously attracts the internal control slider 3, forming a three-level non-contact magnetic force transmission chain of external control-relay-internal control.

[0041] Flexible displacement compensation: When the window is subjected to a small deformation by an external force, the waist-shaped hole connecting piece 8 allows the first relay slider 6 and the second relay slider 7 to produce relative displacement, avoiding misalignment and decoupling of the magnet due to rigid connection.

[0042] Anti-tangling control: such as Figure 5 As shown, the guide groove 501 provides linear constraint on the guide rails 604 and 704, ensuring that the transmission rope is always smoothly wound and released along the preset path.

[0043] Decoupling reset: If the magnets detach, the operator pushes the outer control slider 1 to the upper limit position, and the inner control limit block 4 prevents the inner control slider 3 from moving upward, so that the inner and outer magnets automatically regain adsorption and alignment.
