Abstract
Description
Technical Field
[0001] This utility model belongs to the field of thermal insulation curtain technology, and specifically relates to a thermal insulation curtain device for cold regions. Background Technology
[0002] Existing standard curtains primarily focus on decoration and light blocking, often leaving significant gaps between them and the window frame or wall after installation. In cold regions, cold air enters through these gaps and then through the curtains, making it difficult to maintain a stable indoor temperature.
[0003] For cold regions, tracks are installed on both sides of the window frame, and the end of the curtain's counterweight rod is inserted into the track. At the same time, a soft brush is installed in the track to seal the gap between the curtain and the track, thereby improving the curtain's sealing performance.
[0004] For cold regions, the above-mentioned curtains still cannot provide effective insulation:
[0005] 1. Although a lint brush can fill the gap between the curtain and the track, gaps between the lint brushes are unavoidable, so cold air can still pass through the gaps in the lint.
[0006] 2. As the curtains move up and down repeatedly, the brush rubs against the curtains repeatedly. On the one hand, the pile is easy to fall off, which weakens the sealing performance. On the other hand, it is easy to cause the curtains to wear and tear.
[0007] Based on this, we propose a heat-insulating curtain device for cold regions. Utility Model Content
[0008] The purpose of this utility model is to provide a heat-insulating curtain device for cold regions, aiming to solve the problems existing in the prior art mentioned above.
[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0010] A heat-insulating curtain device for cold regions includes a roller blind box with a curtain roller inside for winding the curtain. A counterweight rod is located at the bottom outer side of the roller blind box. Two sets of track frames are arranged parallel to each other on both sides of the roller blind box, with a base at the bottom of each track frame. The roller blind box, track frames, and bases form a rectangular frame structure. The track frames have a U-shaped groove structure. Both ends of the counterweight rod pass through the track frames. The base has an opening for the counterweight rod to pass through. A first pressure plate is vertically arranged inside the track frame. A first sliding rod is located on one side of the first pressure plate and slides vertically through the side wall of the track frame. A second pressure plate is located at the opening of the base. A second sliding rod is located on one side of the second pressure plate and slides vertically through one side wall of the base. Both the first and second pressure plates are used to press the curtain down. Both the track frames and the base have locking mechanisms for fixing the first and second sliding rods respectively. The curtain is a high-reflectivity curtain.
[0011] Furthermore, the locking mechanism includes a fixed sleeve, an elastic sleeve, and a locking member. The elastic sleeve is embedded in the fixed sleeve and has a connecting portion for connecting to the fixed sleeve. Two sets of arc-shaped elastic plates are spaced apart on the connecting portion. The ends of the arc-shaped elastic plates have a first conical surface. The distance between the two arc-shaped elastic plates gradually increases in the direction away from the connecting portion. The end of the fixed sleeve has an internal thread, and the locking member has an external thread that mates with the thread of the fixed sleeve. The end of the external thread of the locking member has a second conical surface. The second conical surface is used to mate with the first conical surface to close the two arc-shaped elastic plates to fix the first slide rod or the second slide rod.
[0012] Furthermore, a first support plate is provided vertically on one side wall of the track frame and is perpendicularly connected to the inner wall of the track frame. A second support plate is provided horizontally on one side wall of the base and is perpendicularly connected to it. Rubber strips are provided on the outer sides of both the first and second support plates. The curtain abuts against the rubber strips to increase the sealing performance.
[0013] Furthermore, the first support plate extends into the base, and pulleys are respectively provided on both sides of the counterweight rod. The diameter of the pulleys is larger than that of the counterweight rod, and the pulleys slide in cooperation with the rubber strip.
[0014] Furthermore, the roller blind box is equipped with a stepper motor, the curtain roller is equipped with a first helical gear, the output shaft of the stepper motor passes through the roller blind box, and its end is equipped with a second helical gear, the first helical gear meshing with the second helical gear.
[0015] Furthermore, the high-reflectivity curtain is made of aluminized polyester fiber fabric.
[0016] Compared with the shortcomings and deficiencies of existing technologies, this utility model has the following beneficial effects:
[0017] 1. The curtain in this utility model adopts a high-reflectivity curtain to improve the heat insulation capacity of the curtain itself. A first pressure plate is set in the track frame, and the first sliding rod drives the first pressure plate to press the curtain. The position of the first sliding rod is fixed by a locking mechanism. Similarly, a second pressure plate is set at the opening of the base, and the second sliding rod drives the second pressure plate to press the curtain. The position of the second sliding rod is fixed by a locking mechanism. By pressing the sides and bottom of the curtain with the first and second pressure plates, the gap between the curtain and the track frame and the opening of the base is greatly reduced, thereby effectively blocking cold air to achieve the effect of indoor heat preservation.
[0018] 2. The track frame and base are respectively equipped with a first support plate and a second support plate. The first support plate and the second support plate are respectively equipped with rubber strips. The counterweight rod is equipped with pulleys. The pulleys and rubber strips slide together to prevent the counterweight rod from contacting and rubbing against the rubber strips. At the same time, the probability of the curtain contacting and rubbing against the rubber strips is reduced, which can effectively reduce the wear caused by the curtain rising and falling. When the first pressure plate and the second pressure plate press the curtain tightly, the sides and bottom of the curtain abut against the rubber strips, which further improves the sealing performance of the curtain and helps to improve the heat preservation effect of the room.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0032] Example 1
[0033] Reference Figure 1 This embodiment provides a heat-insulating curtain device for cold regions, including a roller blind box 10, a track frame 20, and a base 30. The track frames 20 are arranged parallel to each other on both sides of the window frame. The roller blind box 10 is located at the top of the two track frames 20, and the base 30 is located at the bottom of the two track frames 20. The roller blind box 10, the track frame 20, and the base 30 form a rectangular frame structure. The curtain 40 moves up and down within the frame to realize the unfolding and rolling of the curtain 40.
[0034] Reference Figure 11 The roller blind box 10 is equipped with a curtain roller 12, which is horizontally positioned inside the roller blind box 10. The two ends of the curtain roller 12 are rotatably connected to the inner walls on both sides of the roller blind box 10. The curtain 40 is wound around the curtain roller 12. The curtain 40 is a high-reflectivity curtain, specifically made of aluminized polyester fiber fabric. The aluminized polyester fiber fabric is made by specially treating polyester fibers and coating them with an aluminum film. It combines the durability of polyester fibers with the high reflectivity of aluminum film, and has good heat insulation and light reflection capabilities. At the same time, it is relatively soft and easy to process and install.
[0035] The bottom of the roller blind box 10, located below the curtain roller 12, has a groove. The length of the groove is slightly greater than the width of the curtain 40, and the curtain 40 passes through the groove. (Refer to...) Figure 1 The curtain 40 is equipped with a counterweight rod 41 at the bottom. The counterweight rod 41 is set in a horizontal direction and is located on the outside of the bottom of the roller blind box 10.
[0036] Reference Figure 11 A first helical gear 13 is provided on the curtain roller 12 on one side of the curtain 40. A stepper motor 11 is provided on the outside of the roller blind box 10. The output shaft of the stepper motor 11 passes into the roller blind box 10, and a second helical gear 14 is provided at its end. The second helical gear 14 meshes with the first helical gear 13 for transmission. The stepper motor 11 drives the curtain roller 12 to rotate through the meshing of the first helical gear 13 and the second helical gear 14, thereby realizing the raising and lowering function of the curtain 40.
[0037] Reference Figure 2 and Figure 3 The two side track frames 20 have the same structure, both being U-shaped grooves. The grooves of the two side track frames 20 face each other, and the two ends of the counterweight rod 41 are inserted into the two side track frames 20 respectively, with a gap between the end of the counterweight rod 41 and the inner wall of the track frame 20. The curtain 40 does not contact the track frame 20 during the raising and lowering process, reducing wear and tear between the track frame 20 and the curtain 40 during long-term use.
[0038] Reference Figure 2 The track frame 20 is provided with a first pressure plate 22, which is arranged along the length of the track frame 20 (see reference). Figure 3 One side of the first pressure plate 22 faces the curtain 40, and the other side is provided with a first sliding rod 21. The first sliding rod 21 passes vertically through the side wall of the track frame 20. The track frame 20 is provided with a locking mechanism 50, which is used to fix the position of the first sliding rod 21. At least two first sliding rods 21 are arranged at intervals on the first pressure plate 22.
[0039] Reference Figure 6 and Figure 7The locking mechanism 50 includes a fixed sleeve 51, an elastic sleeve 52, and a locking element 53. The fixed sleeve 51 is vertically inserted through the side wall of the track frame 20. The elastic sleeve 52 is embedded in the fixed sleeve 51. The elastic sleeve 52 includes a connecting part 521, on which two sets of spaced arc-shaped elastic plates 522 are provided. Along the direction away from the connecting part 521, the distance between the elastic plates 522 gradually increases. The ends of the elastic plates 522 have a first conical surface 5221. The connecting part 521 is connected to the fixed sleeve 51, and the first sliding rod 21 passes through the fixed sleeve 51. The fixed sleeve 51 and the elastic sleeve 52 pass through the space between the two arc-shaped elastic plates 522. The fixed sleeve 51 has an internal thread 511 at the outer opening. The locking member 53 has an external thread 531. The external thread 531 of the locking member 53 is threadedly engaged with the internal thread 511 of the fixed sleeve 51. The locking member 53 has a second conical surface 532 at the end of the external thread 531. The second conical surface 532 contacts the first conical surface 5221 and closes the two first conical surfaces 5221 until they abut against the first slide rod 21 to lock and fix the first slide rod 21.
[0040] Reference Figure 2 and Figure 5 The base 30 has an internal cavity with an opening at the top. A counterweight rod 41 enters the cavity through this opening. Along the length of the base 30, a second sliding rod 31 is inserted through one of the side walls, sliding perpendicularly to it. A second pressure plate 32 is located at the end of each sliding rod 31, parallel to the inner wall of the base 30. The base 30 is equipped with a locking mechanism 50 to fix the position of the second sliding rods 31. At least two second sliding rods 31 are spaced apart on the second pressure plate 32.
[0041] The locking mechanism 50 on the track frame 20 has the same structure and function as the locking mechanism 50 on the base 30. Both are used to fix the position of the slide rod. On the base 30, the fixing sleeve 51 of the locking mechanism 50 is vertically sleeved on the side wall of the base 30. The second slide rod 31 passes through the fixing sleeve 51 and the elastic sleeve 52. The locking member 53 is threadedly engaged with the fixing sleeve 51 to lock and fix the second slide rod 31.
[0042] The working process of this embodiment is as follows:
[0043] Curtains open 40 degrees (curtains close 40 degrees)
[0044] First, the stepper motor 11 drives the first helical gear 13 to rotate. The first helical gear 13 meshes with the second helical gear 14, thereby driving the curtain roller 12 to rotate. In conjunction with the counterweight rod 41, the curtain moves downward along the two side track frames 20. The counterweight rod 41 passes through the top opening of the base 30 and enters the base 30.
[0045] Then, on the two side track frames 20, push the first sliding rod 21 so that the first pressure plate 22 causes the curtain 40 to abut against the inner wall of the track frame 20 (see reference). Figure 4 Rotate the locking member 53 so that the second conical surface 532 of the locking member 53 contacts the first conical surface 5221 of the elastic sleeve 52, and gradually close the first conical surfaces 5221 on both sides so that the arc-shaped elastic plates 522 on both sides of the elastic sleeve 52 clamp and fix the first slide rod 21, thereby limiting and fixing the first pressure plate 22.
[0046] Next, push the second sliding rod 31 on the base 30, causing the second pressure plate 32 to bring the curtain 40 into contact with the inner wall of the base 30. Then, lock the locking mechanism 50 (the operation is the same as that of the locking mechanism 50 on the track frame 20, and will not be described again). This achieves the pressing of the sides and bottom edges of the curtain 40, improving the sealing of the sides and bottom edges of the curtain 40, which helps to block cold air from entering the room along the window gaps. Combined with the heat insulation properties of the high-reflectivity curtain material, it helps to improve the indoor heat preservation effect and improve the thermal performance of the window.
[0047] Curtains rolled up to 40 degrees (curtains opened to 40 degrees)
[0048] First, the locking member 53 is rotated in the opposite direction, causing the first conical surface 5221 to gradually separate from the second conical surface 532. The arc-shaped elastic plates 522 on both sides of the elastic sleeve 52 lose their limit and separate from the slide rod, that is, the locking mechanism 50 on the track frame 20 and the base 30 respectively releases the locking limit of the first slide rod 21 and the second slide rod 31.
[0049] Then, start the stepper motor 11 to drive the curtain roller 12 to roll up the curtain 40, so that the counterweight rod 41 rises to the bottom of the roller blind box 10.
[0050] It should be noted that the stepper motor 11 is existing technology. Its specific specifications and power can be selected according to the actual size of the window, curtain 40 and curtain roller 12. The stepper motor 11 has a self-locking function, which can keep the position of the curtain 40 fixed for a long time. The stepper motor 11 can be powered by an indoor socket.
[0051] Example 2
[0052] Example 2 is a further improvement based on Example 1.
[0053] Reference Figure 8 This embodiment provides a heat-insulating curtain device for cold regions. A first support plate 23 is provided vertically on one side wall of the track frame 20. A rubber strip 60 is provided on the side of the first support plate 23 away from the inner wall of the track frame 20 to which it is connected. The distance between the side of the first support plate 23 where the rubber strip 60 is provided and the side of the first support plate 23 connected to the track frame 20 is 5mm-10mm, preferably 5mm.
[0054] Reference Figure 10A second support plate 33 is provided with an opening on the base 30 in the horizontal direction. A rubber strip 60 is provided on the side edge of the second support plate 33 away from the inner wall of the base 30 to which it is connected. The second support plate 33 is located between the extension lines of the first support plates 23 on both sides.
[0055] Reference Figure 9 The first support plate 23 extends into the base 30. Pulleys 42 are provided on both sides of the counterweight rod 41, and the pulleys 42 slide in contact with the rubber strips 60 on both sides. The diameter of the pulleys 42 is slightly larger than that of the counterweight rod 41.
[0056] The working process of this embodiment follows that of Embodiment 1, and the specific process is as follows:
[0057] During the raising or lowering of the curtain 40, the pulley 42 slides along the rubber strip 60 inside the track frame 20. During long-term use, this helps to prevent the counterweight rod 41 from repeatedly rubbing against the rubber strip 60, which would cause wear and tear on the surface of the curtain 40 covering the counterweight rod 41.
[0058] When the counterweight rod 41 moves into the base 30, the first pressure plate 22 in the track frame 20 presses the two sides of the curtain 40, and the curtain 40 abuts against the rubber strip 60. At the same time, the second pressure plate 32 presses the lower part of the curtain 40, and the curtain 40 abuts against the rubber strip 60, which helps to further improve the sealing effect of the curtain 40.
[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
