Description

TECHNICAL FIELD

[0001] The utility model relates to a louver technology, concretely is a hollow glass louver with built-in power-assisted lifting. BACKGROUND

[0002] It is known that in the field of modern building decoration and lighting shading, hollow glass is widely used due to its good heat insulation and sound insulation performance. To further improve its functionality, installing a louver in the middle of the hollow glass has become a common choice. This hollow glass louver, with magnets installed on both sides of the glass, pulls the louver curtain through magnetic interaction to achieve the opening and closing operation of the louver. This method is relatively convenient to operate and meets the needs of users for indoor lighting adjustment and privacy protection to some extent.

[0003] The existing hollow glass louver technology relies on magnets for pulling. Due to the limited magnetism of the magnets, when the number of louver blades is small, the pulling operation is relatively easy. However, as the number of blades increases, the overall weight of the louver curtain increases, and the gravity to be overcome also significantly rises. At this time, the magnetism of the magnets is not enough to provide sufficient pulling force, making it difficult to pull the louver curtain, and the operation experience is greatly discounted. If the magnetism of the magnets is increased, it may also increase the cost and interfere with surrounding electronic devices. SUMMARY

[0004] The utility model aims to provide a hollow glass louver with built-in power-assisted lifting to solve the above-mentioned deficiencies in the prior art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: including: a frame; further comprising:

[0006] A pulley seat is installed at one end of the inner bottom of the frame and rotates the winding wheel inside;

[0007] A fixed pulley is installed at the top of the frame and penetrates the louver pulling rope on the surface;

[0008] A switching structure is installed on one end surface of the winding wheel connected to the pulley seat, dividing the rotation track of the winding wheel into two parts. When a small number of blades are stacked, no assistance is provided to the louver pulling rope. When the number of blades increases, assistance is provided to the louver pulling rope.

[0009] As a further description of the above-mentioned technical scheme: one end of the pulley seat is rotatably installed with a winding wheel through a bearing, and the surface of the winding wheel is provided with a rope groove adapted to the number of louver pulling ropes.

[0010] As a further description of the above technical scheme: the switching structure comprises: a fixed box fixedly installed at the other end of the pulley seat, a spring reel is installed in the fixed box, one end of the spring reel is fixedly connected with a rod sleeve bottom end, the rod sleeve is slidably connected in a spiral groove, the spiral groove is opened at one side end face of the fixed box close to the winding reel, a plug rod is slidably connected in the spiral groove, a sliding rod is arranged at the bottom end of the plug rod, the sliding rod is slidably connected in a sliding groove, and the sliding groove is opened at the other end face of the winding reel.

[0011] As a further description of the above technical scheme: the spiral groove is opened in a mosquito coil shape, and the spiral groove spirally expands outward in a counterclockwise direction, and the rod sleeve is arranged at the middle position of the spiral groove.

[0012] As a further description of the above technical scheme: the louver pulling rope is discharged downward through the fixed pulley and wound on the surface of the winding reel, and the winding reel is provided with a clamping structure on one side to fix the position of the louver pulling rope.

[0013] As a further description of the above technical scheme: the clamping structure comprises: a clamping groove opened at both ends of the pulley seat, and a clamping rod slidably connected in the clamping groove, and the clamping rod is arranged on one side of the winding reel.

[0014] As a further description of the above technical scheme: one end of the louver pulling rope is inserted into a plurality of groups of blades, a magnetic strip is fixedly connected to the middle position of the other end of the louver pulling rope, and a rotating rod is arranged on the side opposite to the louver pulling rope of the frame.

[0015] In the above technical scheme, the hollow glass louver provided with the built-in power-assisted lifting has the following beneficial effects:

[0016] 1. Automatically adapt to power-assisted demand: the winding reel rotating track is divided into two parts by the switching structure, which can automatically adjust the power assistance according to the number of stacked blades. When there are few blades, no additional power assistance is needed, and the louver pulling rope can be easily pulled; when the number of blades increases, the power assistance for the louver pulling rope is automatically increased, which is convenient for users to operate and avoids the problem of difficulty in pulling due to the increase of the number of blades.

[0017] 2. Synergy of power assistance and winding: during the process of lowering the louver, the plug rod and the rod sleeve drive the spring reel to be rewound, and the gravity of multiple blades can also provide power assistance for the winding of the spring reel, realizing the synergy of power assistance and winding, improving the use efficiency of the device, and facilitating the provision of power assistance again next time.

[0038] In use, the louver window is installed in the middle cavity of the double-layer hollow glass, and the louver window is opened and closed by pulling the magnetic strip 16. When the louver window needs to be pulled upward to open, the magnetic strip 16 installed outside the glass and the magnetic strip 16 connected to the middle part of the louver pull rope 3 of the louver window are pulled by magnetic force. During the downward pulling of the louver pull rope 3, the upper end of the louver pull rope 3 contacts the fixed pulley 17, and the lower end of the louver pull rope 3 is wound on the winding wheel 16 with the rotating function. The winding wheel 6 is driven to rotate counterclockwise by contacting the winding wheel 6 in the pulley seat 2. At this time, the louver pull rope 3 moves downward, and the counterclockwise movement of the winding wheel 6 can be divided into two parts:

[0039] The first part, the pull of the blind pull rope 3 pulls the blind up and folds, a small amount of leaf 4 is stacked up and pulled, so the gravity of the leaf 4 is small, the blind pull rope 3 can be easily pulled, and the insertion rod 11 slidingly installed on one end surface of the winding wheel 6 slides in the spiral groove 13, the insertion rod 11 is slidingly connected in the sliding groove 14 through the sliding rod 15, so as to adapt to the change of the position of the insertion rod 11 in the spiral groove 13 during movement, and the insertion rod 11 independently slides in the spiral groove 13 from the center point to the outer ring;
