[0002] Curtains are decorative items used to block windows. General curtains are composed of curtain fabrics, curtain ropes, curtain tracks, curtain accessories, etc. The main functions of curtains include blocking sunlight, reducing indoor temperature, protecting privacy, etc. In addition, curtains can also enhance the beauty and artistic sense of the room. However, the current curtains cannot block rain and cannot meet people's needs. Summary of the Invention

[0003] Based on this, it is necessary to provide a liftable and retractable curtain to solve at least one of the above technical problems.

[0004] A liftable and retractable curtain includes a support frame, a telescopic mechanism and a lifting mechanism. The support frame is installed on the window, the telescopic mechanism is installed above the support frame, and the lifting mechanism is installed below the support frame. The telescopic mechanism includes a rotating component and two telescopic components.

The plurality of sliding rings are all sleeved and slidably sleeved on the middle part of the support rod, and the sliding section is located on one side of the plurality of sliding rings adjacent to the middle part of the support rod. The upper ends of the plurality of connecting rods are respectively hinged to the corresponding sliding rings. The plurality of hinge columns are hinged to the lower ends of two adjacent connecting rods. The fixed ring is fixedly sleeved on the end of the support rod and is hinged to the upper end of the adjacent connecting rod. Among them, the sliding ring adjacent to the center of the support rod is fixedly connected to the sliding section.

[0011] In one embodiment, the louver assembly includes two telescopic louver members. The two telescopic louver members are respectively located at both ends of the support rod, and the tops of the two telescopic louver members are respectively fixedly connected to a plurality of hinge columns.

[0012] In one embodiment, each telescopic louver member includes a plurality of fixed louvers with a trapezoidal side view and a plurality of stretched louvers with a trapezoidal side view. The tops of the plurality of fixed louvers are respectively fixedly connected to a plurality of hinge columns. The plurality of stretched louvers are slidably inserted into the bottoms of the plurality of fixed louvers, and the thickness of the plurality of stretched louvers gradually decreases in the direction towards the bottom.

[0013] In one embodiment, the plurality of fixed louvers include a first louver, a second louver, a third louver and a fourth louver. Slide rails are installed on the side walls of the first louver, the second louver, the third louver and the fourth louver. The first louver is located below the support rod, and one end of the first louver facing the center of the support rod is fixedly connected to the adjacent hinge column. The second louver is slidably inserted into the slide rail of the first louver, and one end of the second louver facing the center of the support rod is fixedly connected to the adjacent hinge column. The third louver is slidably inserted into the slide rail of the second louver, and one end of the third louver facing the center of the support rod is fixedly connected to the adjacent hinge column. The fourth louver is slidably inserted into the slide rail of the third louver. A flexible L-shaped connecting column is installed on the side wall of the fourth louver. One end of the connecting column is fixedly connected to one side of the fourth louver adjacent to the support rod, and the other end is fixedly connected to the sliding section.

[0014] In one embodiment, the water storage and drainage assembly includes two water storage parts, which are respectively installed under the two fourth shutters, each water storage part includes a water storage tank, a water diversion part and a plug, the top of the water storage part is hinged to the bottom plate of the fourth shutter, and a plurality of water outlet holes are opened on the side wall of the bottom of the water storage part away from the support rod, the water diversion part is located on the side of the water storage tank away from the support rod, the plug is inserted on the side wall of the water storage part adjacent to the support rod, the water diversion part includes an L-shaped connecting rod, an inclined rod, a rotating rod and a water diversion plate, one end of the connecting rod is fixedly connected to the end wall of the water storage part, one end of the inclined rod is fixedly connected to the side wall of the water storage part away from the support rod, the two ends of the rotating rod are respectively rotatably inserted into the other end of the connecting rod and the other end of the inclined rod, the water diversion plate is located on the side of the water storage tank away from the support rod, and the rotating rod is fixedly penetrated into the water diversion plate.

[0015] The controller of the present invention can control the forward and reverse rotation of the operating motor, thereby realizing the telescoping of the shutter. When the controller controls the operating motor to reverse, the vertical runner rotates counterclockwise, and the pulling rope follows the rotation of the vertical runner. The pulling rope pulls the two clamping block members towards both ends of the support rod. The sliding ring moves towards the end of the support rod following the clamping block members under the extrusion of the sliding section of the clamping block members. At the same time, the sliding ring extrudes the connecting rod to contract. Thus, the fourth shutter will be inserted into the slide rail of the third shutter, and so on, until the second shutter is inserted into the slide rail of the first shutter, completing the telescoping of the shutter. Then the controller controls the operating motor to rotate forward to close the shutter. By setting up a water storage tank, when it is raining and the window is not closed, the water storage tank will collect rainwater. When the rainwater is collected to a certain extent, the water storage member will pull the stretched shutter downward to close the stretched shutter. Since the support rod is made of flexible material and the whole support rod bends downward, the bending degree gradually increases along the direction towards the middle of the support rod. As the downward bending degree of the support rod becomes larger, the clamping block members and the sliding ring move slowly towards the middle of the support rod, thereby horizontally opening the shutter, enabling the shutter assembly to cover the window, and enabling the shutter assembly to act as a window for rain shielding. At the same time, when the water level inside the water storage tank is high and the pressure becomes large, the water flow discharged from the water outlet hole becomes larger and flows to the upper end of the water diversion plate. Then the upper end of the water diversion plate flips towards the side away from the water storage tank. Under the action of the water diversion plate, the water flows to the wall, on the one hand, for dissipating heat from the wall, and on the other hand, preventing the flowing water from dripping directly, thus preventing the rainwater from splashing and dripping on pedestrians. When the water storage tank is full of rainwater, the side away from the fourth shutter will flip downward, enabling the water in the water storage tank to be discharged faster. At the same time, when the water storage tank is full of rainwater, it will pull the stretched shutter downward, causing at least one end of the telescopic shutter member adjacent to the support rod to tilt downward, enabling the rainwater dripping on the stretched shutter to gather in the water storage tank and flow out of the water storage tank. At the same time, it enables the clamping block members to close faster towards the center of the support rod, thereby enabling the telescopic assembly to close faster and preventing rainwater from entering the room. The structure of the present invention is ingenious and can shield rain when the window is not closed during rain, not only having a sunshading effect but also being able to shield rain.

Among them, the sliding ring 280 adjacent to the center of the support rod 11 is fixedly connected to the sliding section 272.

[0030] As Figure 1 shown, the shutter assembly 31 includes two telescopic shutter members 33. The two telescopic shutter members 33 are respectively located at both ends of the support rod 11, and the tops of the two telescopic shutter members 33 are respectively fixedly connected to the plurality of hinge columns 282.

[0031] As Figure 1 shown, each telescopic shutter member 33 includes a plurality of fixed shutters 34 with a trapezoidal side view and a plurality of stretching shutters 35 with a trapezoidal side view.

The plurality of stretching shutters 35 are slidably inserted into the bottoms of the plurality of fixed shutters 34, and the thickness of the plurality of stretching shutters 35 gradually decreases in the direction towards the bottom.

[0032] As Figure 1As shown, the plurality of fixed shutters 34 include a first shutter 340, a second shutter 341, a third shutter 342 and a fourth shutter 343, and the side walls of the first shutter 340, the second shutter 341, the third shutter 342 and the fourth shutter 343 are all installed with slide rails (not shown in the figure), the first shutter 340 is located below the support rod 11, and one end of the first shutter 340 facing the center of the support rod 11 is fixedly connected to the adjacent hinge column 282, the second shutter 341 is slidably inserted on the slide rail of the first shutter 340, and the second shutter 341 One end facing the center of the support rod 11 is fixedly connected to the adjacent hinged column 282, the third shutter 342 is slidably inserted on the sliding rail of the second shutter 341, the end of the third shutter 342 facing the center of the support rod 11 is fixedly connected to the adjacent hinged column 282, the fourth shutter 343 is slidably inserted on the sliding rail of the third shutter 342, and a flexible L-shaped connecting column 344 is installed on the side wall of the fourth shutter 343, one end of the connecting column 344 is fixedly connected to one side of the fourth shutter 343 adjacent to the support rod 11, and the other end is fixedly connected to the sliding section 272.

[0033] like Figure 1 and Figure 3 As shown, the water storage and drainage assembly 32 includes two water storage parts 320, and the two water storage parts 320 are respectively installed under the two fourth shutters 343. Each water storage part 320 includes a water storage tank 321, a water guide part 322 and a plug. The top of the water storage part 320 is hinged to the bottom plate of the fourth shutter 343. A plurality of water outlet holes 324 are opened on the side wall of the bottom of the water storage part 320 away from the support rod 11. The water guide part 322 is located on the side of the water storage tank 321 away from the support rod 11, and the plug is inserted into the side wall of the water storage part 320 adjacent to the support rod 11. On the top, the water diversion member 322 includes an L-shaped connecting rod 325, a tilting rod 326, a rotating rod 327 and a water diversion plate 328, one end of the connecting rod 325 is fixedly connected to the end wall of the water storage member 320, one end of the tilting rod 326 is fixedly connected to the side wall of the water storage member 320 away from the support rod 11, and the two ends of the rotating rod 327 are rotatably inserted into the other end of the connecting rod 325 and the other end of the tilting rod 326 respectively, the water diversion plate 328 is located on the side of the water storage tank 321 away from the support rod 11, and the rotating rod 327 is fixedly penetrated into the water diversion plate 328.

[0034] During installation: The support frame 10 is installed on the window, the telescopic mechanism 20 is installed above the support frame 10, the lifting mechanism 30 is installed below the support frame 10, the rotating assembly 21 is installed above the support frame 10, both telescopic assemblies 22 are installed on the rotating assembly 21, the water storage and drainage assembly 32 is installed below the shutter assembly 31, the support rod 11 is installed above one side of the window, the horizontal runner 23 is installed above one of the fixing blocks 12, the two parallel runners 24 are respectively installed on both sides of the other fixing block 12, both clamping block members 27 are fixedly installed on the pulling rope 26, both telescopic members 28 are respectively installed at both ends of the support rod 11, and both water storage members 320 are respectively installed below the two fourth shutters 343.

[0035] During use: 1. There is also a controller provided outside the liftable and telescopic curtain. The controller is electrically connected to the operating motor. The controller can control the forward and reverse rotation of the operating motor. When the controller controls the operating motor to reverse, the vertical runner 25 rotates counterclockwise, and the pulling rope 26 follows the rotation of the vertical runner 25, thereby driving the horizontal runner 23 and the two parallel runners 24 to rotate. Among them, the rotation directions of the two parallel runners 24 are opposite. The pulling rope 26 moves, thereby pulling the two clamping block members 27 towards both ends of the support rod 11. The sliding ring 280 moves towards the end of the support rod 11 following the clamping block member 27 under the extrusion of the sliding section 272 of the clamping block member 27. At the same time, the sliding ring 280 squeezes the connecting rod 281 to contract. Furthermore, the fourth shutter 343 will be inserted into the slide rail of the third shutter 342, and so on, until the second shutter 341 is inserted into the slide rail of the first shutter 340, completing the telescoping of the shutters. When the controller controls the operating motor to rotate forward, the vertical runner 25 rotates clockwise, driving the pulling rope 26 to move, pulling the two clamping block members 27 towards the center of the support rod 11, and then closing the shutters, completing the closing of the shutters.

[0036] 2. When it is raining and the window is not closed, the water storage tank 321 of the water storage member 320 will collect rainwater. When the rainwater is collected to a certain extent, the water storage member 320 will pull the stretchable shutter 35 downward, thereby closing the stretchable shutter 35. Also, since the support rod 11 is made of a flexible material and the whole support rod 11 bends downward, the degree of its bending gradually increases along the direction towards the middle of the support rod 11. The downward bending degree of the support rod 11 becomes larger, thereby causing the clamping block member 27 and the sliding ring 280 to slowly move towards the middle of the support rod 11, and then horizontally opening the shutters, that is, the second shutter 341, the third shutter 342, and the fourth shutter 343 are opened, so that the shutter assembly 31 can cover the window, and then the shutter assembly 31 can be used as a window for rain shielding operations.

[0037] 3. When the water storage tank 321 starts to drain water through the water outlet hole 324, due to the relatively low water level and small pressure inside the water storage tank 321, the water flow discharged from the water outlet hole 324 is not sufficient to cause the diversion plate 328 to flip. Under the guidance of the diversion plate 328, it flows vertically downward. When the shutter assembly 31 can cover the window, the water level inside the water storage tank 321 is high and the pressure increases. The water flow discharged from the water outlet hole 324 becomes larger and flows to the upper end of the diversion plate 328, thereby causing the upper end of the diversion plate 328 to flip away from the water storage tank 321. Under the action of the diversion plate 328, the water flow flows onto the wall, on the one hand, for dissipating heat from the wall, and on the other hand, preventing the flowing water from dripping directly, thereby preventing rainwater from splashing and dripping on pedestrians. When the water storage tank 321 is full of rainwater, the side away from the fourth shutter 343 will flip downward, so that the water in the water storage tank 321 can be discharged faster. At the same time, when the water storage tank 321 is full of rainwater, it will pull down the telescopic shutter 35. At least one end of the telescopic shutter member 33 adjacent to the support rod 11 is inclined downward, so that the rainwater dripping onto the telescopic shutter 35 can be collected into the water storage tank 321 and flow out from the water storage tank 321. At the same time, the latch member 27 can be closed faster toward the center of the support rod 11, so that the telescopic assembly 22 can be closed faster to prevent rainwater from entering the room. Between the plurality of telescopic shutters 35 and the plurality of fixed shutters 34, a tension spring (not shown in the figure) is provided between two adjacent telescopic shutters 35 for restoring the telescopic shutter 35.

[0038] Beneficial effects: The controller of the present invention can control the forward and reverse rotation of the operating motor, thereby realizing the telescoping of the shutter. When the controller controls the operating motor to reverse, the vertical runner 25 rotates counterclockwise, and the pulling rope 26 follows the rotation of the vertical runner 25. The pulling rope 26 pulls the two clamping members 27 towards both ends of the support rod 11. The sliding ring 280 moves towards the end of the support rod 11 following the clamping member 27 under the extrusion of the sliding section 272 of the clamping member 27. At the same time, the sliding ring 280 extrudes the connecting rod 281 to contract, and thus the fourth shutter 343 will be inserted into the slide rail of the third shutter 342, and so on, until the second shutter 341 is inserted into the slide rail of the first shutter 340, completing the telescoping of the shutter. The controller controls the operating motor to rotate forward to close the shutter. By providing the water storage tank 321, when it is raining and the window is not closed, the water storage tank 321 will collect rainwater. When the rainwater is collected to a certain extent, the water storage member 320 will pull the stretchable shutter 35 downward to close the stretchable shutter 35. Since the support rod 11 is made of a flexible material and the whole support rod 11 bends downward, the bending degree increases gradually along the direction towards the middle of the support rod 11. As the downward bending degree of the support rod 11 becomes larger, the clamping member 27 and the sliding ring 280 move slowly towards the middle of the support rod 11, thereby horizontally opening the shutter, enabling the shutter assembly 31 to cover the window, and enabling the shutter assembly 31 to act as a window for rain shielding. At the same time, when the water level inside the water storage tank 321 is high and the pressure becomes large, the water flow discharged from the water outlet hole 324 becomes larger and flows to the upper end of the water diversion plate 328. As a result, the upper end of the water diversion plate 328 flips towards the side away from the water storage tank 321. Under the action of the water diversion plate 328, the water flows onto the wall, on the one hand, for dissipating heat from the wall, and on the other hand, preventing the flowing water from dripping directly, thereby preventing the rainwater from splashing and dripping on pedestrians. When the water storage tank 321 is full of rainwater, the side away from the fourth shutter 343 will flip downward, enabling the water in the water storage tank 321 to be discharged faster. At the same time, when the water storage tank 321 is full of rainwater, it will pull the stretchable shutter 35 downward, and at least one end of the telescopic shutter member 33 adjacent to the support rod 11 will incline downward, enabling the rainwater dripping onto the stretchable shutter 35 to converge into the water storage tank 321 and flow out from the water storage tank 321. At the same time, it enables the clamping member 27 to close faster towards the center of the support rod 11, thereby enabling the telescopic assembly 22 to close faster and preventing rainwater from entering the room. The structure of the present invention is ingenious and can shield rain when the window is not closed during rain, not only having a sunshade function but also being able to shield rain.
