Description

Technical Field

[0001] The utility model relates to a magnetic synchronizer, in particular to a magnetic synchronizer suitable for a three-glass two-cavity blind. Background Art

[0002] Currently, triple-glazed, dual-chamber windows with built-in Venetian blinds require the ability to raise and lower the blinds and adjust their angles. Traditionally, mechanical transmission has been employed, resulting in low efficiency, high wear, and a short service life.

[0003] Although the existing magnetic transmission device solves some of the problems, in the three-glass two-cavity structure, since the glass cavities on both sides are far apart, the magnetic adsorption force between the driving motor and the driven end is insufficient, and the driving force cannot be effectively transmitted. Utility Model Content

[0004] The purpose of the utility model is to provide a magnetic synchronizer with a simple structure, low manufacturing cost, long service life and easy maintenance, which is particularly suitable for three-glass two-cavity built-in blinds glass windows. By installing a magnetic synchronizer in the middle cavity, the driving force of the driving motor is effectively transmitted to the driven end, thereby realizing the synchronous operation of the blinds.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A magnetic synchronizer suitable for triple-glazed, two-chamber blinds comprises a housing, an inner cavity of the housing being provided with a bearing column, a bearing, a turntable shaft cylinder and a magnetic turntable being mounted on the bearing column; a center hole being provided in the center of the magnetic turntable, two turntable shaft cylinders being symmetrically mounted in the center holes on both sides of the magnetic turntable; and two bearings being symmetrically mounted in the turntable shaft cylinders on both sides.

[0007] According to a further preferred technical solution, the shell is composed of two half shells that are interlocked together, and both half shells are provided with matching plug posts and post holes.

[0008] According to a further preferred technical solution, the housing is made of plastic.

[0009] According to a further preferred technical solution, the bearings and the turntable shaft are both made of magnetically adsorbable iron material, so that the two symmetrical bearings and the bearing seats can attract each other and be firmly fixed on the magnetic turntable.

[0010] According to a further preferred technical solution, the magnetic turntable is in the shape of a circular ring.

[0011] A further preferred technical solution is that the turntable shaft cylinder includes a cylinder body portion and a cylinder body limiting ring portion, the cylinder body portion is a hollow cylindrical design, and a bearing mounting groove is provided inside it for installing bearings; the cylinder body limiting ring portion is fixed on the outer ring edge of one end of the cylinder body portion, and is a ring-shaped protruding structure.

[0012] The beneficial effects of the utility model are:

[0013] This new magnetic synchronizer features a simple structure, low manufacturing cost, easy installation, and a long service life. Its magnetic transmission eliminates mechanical wear and provides efficient and stable transmission. It is particularly suitable for triple-pane, dual-chamber windows with built-in Venetian blinds, effectively transmitting the driving force of the drive motor to the driven end, achieving synchronized operation of the blinds.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] The utility model provides a magnetic synchronizer suitable for three-glass two-cavity blinds, such as Figure 1 and 2 The magnetic synchronizer comprises a housing 1, within which a bearing column 2 is positioned. A bearing 3, a turntable shaft cylinder 4, and a magnetic turntable 5 are mounted in sequence on the bearing column 2. The magnetic turntable 5 has a central hole 51, and two turntable shaft cylinders 4 are symmetrically mounted within the central holes 51 on either side of the magnetic turntable 5, ensuring a secure connection between the turntable shaft cylinders 4 and the magnetic turntable 5.

[0021] like Figure 2 As shown, the housing 1 consists of two interlocking halves, each equipped with matching pins 11 and holes 12 for easy assembly and disassembly. To reduce overall weight and cost, the housing 1 is made of plastic. The bearings 3 and the turntable shaft 4 are both made of magnetic materials (such as iron). These materials generate a strong attraction with the magnetic turntable 5, thereby enhancing the connection strength between the components.

[0022] like Figure 3 As shown, the structure of the turntable shaft cylinder 4 is relatively special, including a barrel portion 41 and a barrel portion limiting ring portion 42. The barrel portion 41 is a hollow cylindrical design, and a bearing mounting groove is provided inside it for mounting the bearing 3. The barrel portion limiting ring portion 42 is fixed on the outer ring edge of one end of the barrel portion 41 and is an annular protruding structure. The function of the barrel portion limiting ring portion 42 is to limit the axial movement of the barrel portion 41 and, by increasing the adsorption area with the magnetic turntable 5, enable the turntable shaft cylinder 4 and the magnetic turntable 5 to be firmly combined, ensuring that they remain synchronized during rotation.

[0023] like Figure 4 As shown, the magnetic turntable 5 has a circular ring structure, which is conducive to uniform distribution of the magnetic field and improved transmission efficiency. The barrel portion 41 of the turntable shaft cylinder 4 is designed to enable it to be stably mounted on the bearing column 2 and maintain good contact with the magnetic turntable 5 through the barrel limit ring portion 42, thereby ensuring synchronous rotation.

[0024] Working principle:

[0025] When the drive motor is activated, its driving force is transmitted to the magnetic turntable 5 via magnetic force, which in turn drives the turntable shaft 4 and bearing 3 to rotate synchronously. Because the turntable shaft 4 is tightly connected to the bearing 3, this rotational motion is transmitted through the bearing column 2, ultimately achieving synchronous operation of the Venetian blinds. The retaining ring 42 of the turntable shaft 4 not only increases the surface area for the magnetic turntable 5 but also acts as a fixed anchor, ensuring stability during transmission.

[0026] This magnetic transmission method avoids mechanical wear. The evenly distributed magnetic force and strong adsorption ensure smooth and efficient transmission, making it particularly suitable for triple-glazed, dual-chamber windows with built-in Venetian blinds. By simplifying the structure and using appropriate materials, this design reduces manufacturing costs and extends service life. Furthermore, it is easy to install and maintain, making it highly practical.

[0027] It should be noted that, in this document, terms such as "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
