Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of rolling curtains, and in particular relates to a telescopic rolling curtain. Background Art
[0002] During the use of ordinary retractable roller blinds, if the size of the retractable roller blinds does not match the window frame, for example, the size of the retractable roller blinds is smaller than the window frame, the roller blinds will hit the glass curtain wall or glass window when they are retracted or released or when there is wind. On the other hand, the window frame is tilted from the horizontal plane, and the roller blinds will remain vertically drooping under the action of gravity. When the roller blinds are rolled up or released, they are more likely to hit the glass curtain wall or glass window.
[0003] Special-shaped window frames refer to windows whose frame shape is not a common rectangle, but has a special shape and design. This kind of window frame is usually used in special buildings or design projects, and it can bring unique aesthetic effects and functional characteristics compared to rectangular or square window frames. The shape and design of special-shaped window frames can be customized according to specific needs and architectural styles, such as round, fan-shaped, triangular, diamond, trapezoidal and polygonal. These shapes can bring different light and visual effects, creating a unique atmosphere and sense of space. Rectangular window frames are generally used with rectangular glass. The main disadvantage of rectangular window frames is that the shape and lines of rectangular window frames are relatively simple, which is easy to appear monotonous and lacks personality and diversified design. In order to make the window frame and the glass used with it more design-oriented, the rectangular window frame can be tilted with the horizontal plane, the window frame can be designed into a special-shaped window frame with a special shape, or the special-shaped window frame can be further tilted with the horizontal plane.

DETAILED DESCRIPTION
[0026] In order to facilitate the understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the relevant drawings.
[0027] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to another element and integrated therewith, or there may be an intermediate element at the same time. The terms "installed", "one end", "the other end" and similar expressions used herein are for illustrative purposes only.
[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used in the specification herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0029] Please refer to Figure 1-Figure 8The utility model provides a telescopic rolling curtain, which includes a rolling curtain body 102 and a rolling-up and unwinding mechanism 101 connected to the rolling curtain body 102. The rolling-up and unwinding mechanism 101 rolls up or releases the rolling curtain body 102 along a first direction, and the rolling curtain body 102 gradually widens along the rolling direction. Side slide rails 300 are arranged on both sides of the rolling curtain body 102 along a second direction. A telescopic connection component 200 is connected to the narrower end of the rolling curtain body 102. The telescopic connection component 200 is arranged along the second direction, and the two ends of the telescopic connection component 200 are respectively slidably connected to the side slide rails 300 on both sides; when the rolling curtain body 102 is rolled up or released, the telescopic connection component 200 is driven to move along the first direction, and the telescopic connection component 200 is extended or shortened along the second direction, so that its length is adapted to the distance between the side slide rails 300 on both sides, and the two ends of the telescopic connection component 200 always remain connected to the side slide rails 300 on both sides.
[0030] The telescopic roller blind provided by the utility model has side slide rails 300 arranged on both sides of the roller blind body 102 along the second direction, and a telescopic connection assembly 200 is connected to the narrower end of the roller blind body 102, and the two ends of the telescopic connection assembly 200 are respectively slidably connected to the side slide rails 300 on both sides; when the roller blind body 102 is rolled up or released, the telescopic connection assembly 200 is driven to move along the first direction, and the telescopic connection assembly 200 is extended or shortened along the second direction, so that its length is adapted to the distance between the side slide rails 300 on both sides, and the two ends of the telescopic connection assembly 200 are always connected to the side slide rails 300 on both sides, that is, the roller blind body 102 is always in the side slide rails 300 when rolled up or released, so that the problem of "the roller blind will hit the glass curtain wall or glass window during use" can be well solved. Secondly, the roller blind body 102 and the side slide rails 300 on both sides are gradually widened along the rolling direction, and the utility model also has the advantages of special-shaped window frame design.
[0031] Furthermore, the rectangular window frame is tilted with the horizontal plane, the window frame is designed into a special-shaped window frame, or the special-shaped window frame is further tilted with the horizontal plane. Such a design, combined with the rectangular curtain, is prone to curtain light leakage or aggravates the situation of the roller shutter hitting the glass curtain wall and glass window. Specifically, it is embodied in: 1. The design and operation of the ordinary electric roller shutter mechanism is based on the conventional square structure of the window frame. In this structure, the roller shutter can be easily raised and lowered vertically, but when the shape of the window frame changes, the roller shutter mechanism may not be able to move smoothly on the track, which may easily cause the roller shutter to hit the inclined window frame glass or the special-shaped window frame glass. 2. Conventional window frames and conventional roller shutters can be easily raised and lowered vertically and can completely cover the window opening; however, when the window frame structure becomes a special-shaped structure, the roller shutter mechanism may not be able to adapt to this shape, resulting in an unblocked triangular area after closing. The utility model can well solve the above-mentioned problems of "curtain light leakage or hitting the glass curtain wall and glass window".
[0032] Please refer to Figure 1-Figure 8 In a preferred embodiment, the telescopic connection assembly 200 includes a pulley 201, an outer telescopic rod 202 and an inner telescopic rod 203.

The free ends of the outer telescopic rod 202 and the inner telescopic rod 203 are respectively connected to the pulley 201. The free ends of the outer telescopic rod 202 and the inner telescopic rod 203 refer to the end of the outer telescopic rod 202 away from the sleeve and the end of the inner telescopic rod 203 away from the sleeve, respectively. Figure 2 For reference, they are the left end of the outer telescopic rod 202 and the right end of the inner telescopic rod 203 respectively; the inner side of the side slide rail 300 is respectively provided with a wheel body sliding groove 301 with an opening facing inward, and the opening facing inward means that the opening faces the curtain body in the middle, and the wheel body sliding groove 301 is arranged along the axial direction of the side slide rail 300. When the rolling curtain body 102 is rolled up or released, the wheel body of the pulley 201 is always slidably connected in the corresponding wheel body sliding groove 301. The pulley 201 is arranged to reduce friction and improve the performance of the telescopic rolling curtain. Of course, in some embodiments, the telescopic connection assembly 200 can use two telescopic slide rails, telescopic rods with elastic structures or other existing technologies when realizing telescopic movement; the pulley 201 can also use a slider slidably connected in the wheel body sliding groove 301 or a sliding sleeve slidably sleeved on the outer periphery of the side slide rail 300 in some embodiments. The above arrangement facilitates the overall assembly of the telescopic connection assembly 200, the assembly of the pulley 201, the outer telescopic rod 202 and the inner telescopic rod 203.
[0033] Please refer to Figure 6-Figure 7 In a preferred embodiment, the outer telescopic rod 202 is provided with a rod telescopic channel 204 for the inner telescopic rod 203 to be telescopically connected. The rod telescopic channel 204 penetrates the outer telescopic rod 202 in the axial direction. The outer rod cover 205 is detachably installed at the openings at both ends of the rod telescopic channel 204 of the outer telescopic rod 202. The outer rod cover 205 at the free end of the outer telescopic rod 202 is detachably connected to the corresponding pulley 201. The outer rod cover 205 at the sleeve end is also provided with an inner rod avoidance hole for the inner telescopic rod 203 to telescopically move in the rod telescopic channel 204; the free end of the inner telescopic rod 203 is detachably connected to the corresponding pulley 201. Further, two outer rod covers 205 and two inner rod covers 206 are respectively fixed to the left and right ends of the outer telescopic rod 202 and the left and right ends of the inner telescopic rod 203 by screws, and the outer telescopic rod 202 and the inner telescopic rod 203 are respectively provided with threaded holes that match the screws. Of course, the cover and the telescopic rod can also be matched by a snap connection or a cover connection.
[0034] In a preferred embodiment, the sleeve end and the free end of the inner telescopic rod 203 are both detachably mounted with an inner rod cover 206, and the inner rod cover 206 at the free end of the inner telescopic rod 203 is detachably connected to the corresponding pulley 201; the inner rod avoidance hole limits the inner rod cover 206 at the sleeve end of the inner telescopic rod 203 to move outward and / or the total length of the outer telescopic rod 202 and the inner telescopic rod 203 is greater than the distance at the wider interval of the side slide rail 300. Through the above arrangement, it is ensured that the inner telescopic rod 203 and the outer telescopic rod 202 are always connected during the process of rolling up or releasing the roller shutter body 102.
[0035] Please refer to Figure 1 , Figure 6 and Figure 7 In a preferred embodiment, the outer telescopic rod 202 is axially provided with a curtain body plug-in groove 208, and the narrower end of the curtain body of the rolling curtain body 102 is connected with a connector 207 that matches the curtain body plug-in groove 208. The connector 207 is axially plugged into the curtain body plug-in groove 208 by the outer telescopic rod 202, and is generally inserted into the openings at the left and right ends of the curtain body plug-in groove 208. A curtain body avoidance opening is provided on the side of the curtain body plug-in groove 208 close to the rolling curtain body 102. The curtain body avoidance opening is used for the rolling curtain body 102 to extend into the curtain body plug-in groove 208, and the rolling curtain body 102 is led out of the curtain body plug-in groove 208 through the avoidance opening, and the curtain body avoidance opening limits the movement of the connector 207 along the winding direction. The plug-in component 207 can be set to a cylindrical shape, and the cross section of the curtain body plug-in groove 208 is also similarly circular. The diameter of the plug-in component 207 is smaller than the cross-sectional diameter of the curtain body plug-in groove 208 and larger than the curtain body avoidance opening width.
[0036] Please refer to Figure 6-Figure 7 At least one of the outer telescopic rod 202 and the inner telescopic rod 203 is provided with a counterweight groove 209, and the counterweight groove 209 is used to accommodate a counterweight block 210. The counterweight block 210 can keep the roller shutter body 102 taut and drooping through its total amount to maintain beauty. At the same time, the counterweight block 210 can also be made of low-cost materials to reduce the overall cost of the telescopic roller shutter.
[0037] Please refer to Figure 6-Figure 8In a preferred embodiment, a wheel body sliding groove 301 is axially arranged in the side sliding rail 300, and pulleys 201 are respectively arranged at both ends of the telescopic connection assembly 200 along the second direction. One end of the pulley 201 is slidably connected to the wheel body sliding groove 301, and the other end is hinged to the telescopic connection assembly 200, so that the angle between the pulley 201 and the telescopic connection assembly 200 matches the angle between the telescopic connection assembly 200 and the side sliding rail 300, so as to ensure that the pulley 201 runs more smoothly between the guide rails on both sides. The pulley 201 is hinged to the telescopic connection assembly 200 to ensure that the pulley 201 can make a cone-like rotation around the hinge point. When the pulley 201 is installed in the two side slide rails 300, its inclination angle can be adapted; for example, when the side slide rails 300 and the telescopic connection assembly 200 are vertically arranged, the pulley 201 remains vertical to the telescopic connection assembly 200 during installation and use. If the side slide rails 300 and the telescopic connection assembly 200 are 135°, the angle between the pulley 201 and the telescopic connection assembly 200 is 135°. The above angle refers to the angle located in the roller shutter body 102.
[0038] In a preferred embodiment, the wheel body sliding groove 301 is also provided with a side sliding opening 302, and the wheel body sliding groove 301 and the side sliding opening 302 both penetrate through both ends of the side sliding rail 300 along the first direction; one end of the wheel body of the pulley 201 is slidably connected in the wheel body sliding groove 301, and the other end passes through the side sliding opening 302 to be connected with the telescopic connection component 200, and the inner wall of the side sliding opening 302 is located on both sides of the telescopic connection component 200 and is provided with anti-noise rubber strips 304, when the telescopic connection component 200 moves along the first direction, the anti-noise rubber strips 304 are used to prevent the telescopic connection component 200 from contacting the inner wall of the side sliding opening 302, and the telescopic connection component 200 avoids contacting with metal devices such as the side sliding rail 300 to produce a large noise. Furthermore, the side slide rail 300 is provided with installation openings at the upper and lower ends thereof which are connected to the wheel body sliding groove 301 and are used to install one end of the wheel body of the pulley 201 into the wheel body sliding groove 301 ; the installation opening at the lower end is also provided with a slide rail cover 303 which matches therewith.
