Description

Technical Field

[0001] The utility model relates to the technical field of hollow louver windows, and particularly relates to an ultra-short internal control slider applicable to short-stroke hollow louver windows. Background Art

[0002] A hollow louver window is a building window structure integrating light shading and aesthetics, and its core control component is an internal control slider. The internal control slider is usually installed inside the side frame of the window body, and drives the curtain pull rope by sliding up and down, so as to realize the flipping and lifting of the louver curtain. The slider is located between the interlayers of two glass covers and is adsorbed by an external magnetic handle, which is convenient for users to perform operation control outside.

[0003] In the design of traditional hollow louver windows, the length of the internal control slider is relatively long to ensure sufficient sliding stroke to smoothly complete the lifting and flipping control of the louver curtain. However, in some windows with smaller sizes, due to limited space in the window body, the sliding stroke of the internal control slider is restricted, resulting in the inability to fully lift and lower the louver curtain. This limitation directly affects the user experience and makes it impossible to effectively control the louver curtain in a limited space.

[0004] To meet the use requirements of small-sized window bodies, the market urgently needs an internal control slider that can adapt to short strokes. This slider not only needs to complete the lifting and lowering operations of the louver curtain within a limited sliding stroke, but also needs to maintain a small structure, complete functions, and be easy to install and operate. Therefore, it has important practical value to design an ultra-short internal control slider applicable to short-stroke window bodies. Summary of the Utility Model

[0005] The technical objective of the utility model is to provide an ultra-short internal control slider applicable to short-stroke hollow louver windows, which can not only complete the lifting and lowering operations of the louver curtain within a limited sliding stroke, but also maintain a small structure, complete functions, and be easy to install and operate.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0007] An ultra-short internal control slider applicable to short-stroke hollow louver windows includes a slider body. The slider body is designed with an inner and outer double-layer cavity structure. A magnetic block cavity and two roller cavities are arranged on its outer layer, and a magnetic block and rollers are respectively installed therein; a movable pulley cavity and a spring cavity are arranged on its inner layer, and a movable pulley and a spring are respectively installed therein; the magnetic block cavity is arranged between the two roller cavities; the movable pulley cavity is arranged above the spring cavity; two top wire outlets are arranged on the top surface of the movable pulley cavity; and a bottom wire outlet is arranged on the bottom surface of the spring cavity.

[0008] According to a further preferred technical solution, a wire winding hook is provided on the outer layer of the bottom surface of the slider body, and the hook opening corresponds to the bottom wire outlet. The design of the wire winding hook enables the slider body to be placed horizontally in the slide groove after winding, otherwise the bottom of the slider body will be tilted.

[0009] According to a further preferred technical solution, openings are provided on both sides of the movable pulley cavity to facilitate the installation of the movable pulley.

[0010] According to a further preferred technical solution, the opening width of the bottom wire outlet is smaller than the diameter of the spring, thereby playing the role of a limit spring.

[0011] According to a further preferred technical solution, a tie hole is provided between the two top wire outlets for fixing one end of the lifting rope.

[0012] According to a further preferred technical solution, a wire avoidance opening is provided on the top surface of the pulley cavity above the magnetic block cavity. After the lifting rope is fixed in the wire tie hole, it passes through the wire avoidance opening.

[0013] A further preferred technical solution is that a magnet insertion opening is provided on one side of the magnet cavity, and the edge of the opening of the magnet cavity extends inwardly, so that the length and width of the edge of the opening are smaller than the magnet cavity, thereby confining the magnet in the magnet cavity to prevent overflow.

[0014] The beneficial effects of the utility model are:

[0015] The following is a description of the technical advantages of the ultra-short internal control slider:

[0016] 1. Small size, suitable for short-stroke windows: The ultra-short internal control slider adopts a compact double-layer cavity structure design, which reduces the overall length of the slider body and is very suitable for small-sized hollow blinds, especially for windows with short strokes. This design can realize the lifting and lowering control of the blinds in a limited space, effectively solving the technical problem that the traditional internal control slider cannot be fully lifted and lowered in short-stroke windows.

[0017] 2. Efficient rope transmission control: The upper and lower layers of the slider body are respectively equipped with rollers, movable pulleys and spring cavities. The reasonable layout ensures the smooth operation of the rope transmission. The design of the top and bottom wire outlets of the movable pulley enables the rope to efficiently transmit power to achieve the lifting and flipping operations of the blinds. The design of the winding hook further ensures the smooth operation of the slider body in the slide slot to prevent tilting or instability.

[0018] 3. Convenient magnetic operation: The magnetic block cavity on the upper layer of the slider body is located between the two roller cavities. The magnetic block is adsorbed to the slider through the external magnetic handle. The user can easily operate the internal control slider through the external handle, and the control experience is simple and smooth.

[0019] 4. Easy installation and maintenance: The opening design on both sides of the movable pulley cavity makes the installation and maintenance of the movable pulley more convenient, reduces the complexity of disassembly and assembly, and improves the usability of the product. At the same time, the limit design of the bottom wire outlet ensures the stability of the spring and the pull rope, avoiding failures caused by pulling force or spring displacement.

[0020] 5. Design to prevent component spillage: The magnetic block cavity is provided with a limit structure, and the edge of the cavity opening extends inward, enabling the magnetic block to be safely fixed in the magnetic block cavity, avoiding the risk of magnetic block spillage during use, and further enhancing the durability and safety of the product.

[0021] 6. Strong stability and prevention of pull rope entanglement: The wire avoidance opening design on the top surface of the pulley cavity allows the lifting pull rope to pass through this opening during operation, avoiding the entanglement or jamming of the pull rope in the slider cavity, and improving the smoothness and stability of the operation.

[0022] With these technical advantages, this ultra-short internal control slider not only meets the control requirements of short-stroke blinds but also features a small size, convenient operation, simple installation, and strong stability, significantly improving the practicality of the product and the user experience.

Detailed Embodiments

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Specific embodiments:

[0029] Embodiment 1:

[0030] An ultra-short internal control slider applicable to short-stroke hollow blinds, asFigures 1 to 3 As shown in the figure, it includes a slider body 1, which is designed with a double-layer cavity structure inside and outside. The double-layer cavity is used to accommodate key components such as magnetic blocks, rollers, movable pulleys, and springs respectively, so as to realize the lifting and flipping control of the shutter.

[0031] Specifically, on the outer layer of the slider body 1, there are:

[0032] A magnetic block cavity 3, which is used to accommodate a magnetic block (not shown) and is located between two roller cavities 2;

[0033] Two roller cavities 2, in which rollers (not shown) are respectively installed. The rollers can enable the slider to slide smoothly during the installation process.

[0034] On the inner layer of the slider body 1, there are:

[0035] A movable pulley cavity 4, in which a movable pulley (not shown) is installed, used to control the sliding of the pulling rope and the flipping of the shutter curtain. There are two top wire outlets 5 on the top surface of the movable pulley cavity, which are convenient for the pulling rope to pass through the top wire outlets and guide the sliding.

[0036] A spring cavity 6, in which a spring (not shown) is installed. The spring is used to provide tension to ensure that the slider is in a stable state during the lifting process of the shutter curtain. There is a bottom wire outlet 7 on the bottom surface of the spring cavity, and the pulling rope can be led out from the bottom wire outlet and connected to the shutter curtain.

[0037] To ensure the stability of the slider body, a winding hook 8 is provided at the outer position of the bottom surface of the slider body 1, and its hook mouth corresponds to the bottom wire outlet. The winding hook can effectively wind and fix the pulling rope on the slider body and keep it horizontal in the chute, preventing the slider body from tilting due to uneven pulling force.

[0038] To further optimize this design, there are openings on both sides of the movable pulley cavity 4. Such a design is convenient for the installation and disassembly of the movable pulley, making maintenance more convenient. The opening width of the bottom wire outlet 7 is smaller than the diameter of the spring. This design can effectively limit the spring and prevent the spring from shifting due to the traction of the pulling rope, ensuring the stability of the internal structure of the slider during operation.

[0039] In specific applications, one end of the pulling rope is connected to the movable pulley cavity through the top wire outlet 5. There is also a tying hole 9 between the top wire outlets of the movable pulley cavity, which is used to fix one end of the lifting pulling rope, so that the pulling rope is fixed inside the slider and prevent it from loosening during operation.

[0040] In addition, to avoid the pulling rope from being wound or blocked, a wire avoiding port 10 is also provided on the top surface of the pulley cavity. After the pulling rope passes through the wire avoiding port, it can continue to perform smooth lifting operations, thus avoiding the interference problem between the pulling rope and the slider structure during operation.

[0041] To prevent the magnetic block from coming out, a magnetic block insertion port 11 is provided on one side of the magnetic block cavity 3. The edge of the cavity opening of the magnetic block cavity extends inward, so that the length and width of the cavity opening are smaller than the overall size of the magnetic block cavity. Such a design ensures that the magnetic block can be firmly fixed in the cavity, avoiding functional failure caused by the overflow of the magnetic block during use.
