Description

Technical Field

[0001] The present application relates to the field of curtains, and in particular to a flame-retardant curtain end cover. Background Art

[0002] At present, roller curtains are a commonly used shading device and are widely used in various indoor shading occasions. Their basic structure includes a roller tube and a curtain body. The curtain body is retracted and extended by the rotation of the roller tube, and the roller tube is positioned and supported by the end caps at both ends.

[0003] Regarding the above-mentioned related technologies, there are still defects: when using end covers to connect the reel or guide rails, bolts are usually used for fixed connection. However, when bolts are used for installation, if the reel needs to be repaired or replaced during the connection process, the reel needs to be disassembled and assembled with the end cover as a whole, which is cumbersome and inconvenient to use. Utility Model Content

[0004] In order to facilitate the installation of the end cover and simplify the disassembly and installation steps, the present application provides a flame-retardant curtain end cover.

[0005] The flame-retardant curtain end cap provided in this application adopts the following technical solution:

[0006] A flame-retardant curtain end cover includes a guide rail and a roller, on which sunshade fabric is rolled up. The guide rail and the roller are connected by an end cover. The end cover includes a fixing part and a matching kit. The matching kit is sleeved on the guide rail or the roller, and the fixing part is provided with a matching cavity for inserting the end of the matching kit. The end of the matching kit inserted into the fixing part is connected to a spring and an elastic bridge block. The elastic bridge block can be deformed toward the direction of the matching kit, and the fixing part is provided with a through hole for the elastic bridge block to pass through.

[0007] Optionally, the mating kit includes an upper end piece, one end of which is provided with an upper end cavity for the guide rail end to be embedded, and the spring and the elastic bridge block are fixedly connected to the end of the upper end piece away from the upper end cavity; a polygonal release piece is slidably connected to the fixed piece, and when the polygonal release piece is located above the through hole, the elastic bridge block rebounds back into the mating cavity.

[0008] Optionally, the mating kit also includes a lower end piece, which is provided with a lower end cavity for inserting the rolling roller, and the spring and the elastic bridge block are fixedly connected to the end of the lower end piece away from the lower end cavity; a circular ejection piece is also slidably connected to the fixed piece, and when the circular ejection piece is located above the through hole, the elastic bridge block rebounds back into the mating cavity.

[0009] Optionally, a connecting block is provided at one end of the fixing part away from the mating kit, the fixing part is arranged in parallel and fixedly connected to the connecting block, and one end of the connecting block is connected to the upper end part and the lower end part, and the magnetic part can be magnetically connected to the upper end part or the lower end part.

[0010] Optionally, the circular ejection piece is in close contact with the outer side surface of the lower end piece, and the polygonal ejection piece is in close contact with the outer side surface of the upper end piece; the end of the fixing piece away from the connecting block is fixedly connected to the limiting block, and the limiting block protrudes toward the outer wall of the fixing piece.

[0011] Optionally, the circular ejection piece and the polygonal ejection piece are both provided with a plurality of anti-slip grooves.

[0012] Optionally, a threaded hole is passed through the connection block, a suction cup is fixedly connected to the opening of the threaded hole, and a screw is threadedly connected to the inner thread of the threaded hole.

[0013] Optionally, the surface of the end cover is coated with an inorganic phosphorus layer.

[0014] To sum up, the beneficial technical effect of the present application is that when it is necessary to connect the end cover member with the guide rail and the rolling roller, it is only necessary to move the guide rail toward the upper end member and insert it into the upper end cavity. At this time, the elastic bridge block will automatically be inserted into the through hole, thereby achieving a relatively fixed connection between the guide rail and the end cover member; if the rolling roller is moved toward the lower end member and inserted into the lower end cavity, the elastic bridge block will automatically be inserted into the through hole, thereby achieving a relatively fixed connection between the rolling roller and the end cover member.

[0015] If the end cover needs to be separated from the guide rail or the rolling roller, it is only necessary to pull the circular or polygonal separation piece to retract the spring and the elastic bridge block into the matching cavity. Finally, the user can pull the guide rail or the rolling roller to separate them. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-6 This application is described in further detail.

[0024] The embodiment of the present application discloses a flame retardant curtain end cap. Figure 1 A flame-retardant curtain end cap includes a guide rail 1 and a roller 2. The roller 2 is loaded with sunshade fabric. When the curtain is used, the user pulls the curtain, causing the roller 2 to rotate and release the curtain to block sunlight. End caps 3 are mounted on both sides of the roller 2 and the guide rail 1, securing the roller 2 and the guide rail 1 relative to each other.

[0025] Reference Figures 2 to 5 The end cap 3 includes a fixing member 4 and a mating member 5. The mating member 5 can be mounted on the roller shutter roller 2 or the guide rail 1. The mating member 5 is then connected to the end cap 3 to achieve a relatively fixed connection between the roller shutter roller 2 and the guide rail 1. The outer surface of the end cap 3 is also coated with an inorganic phosphorus layer. The inorganic phosphorus flame retardant has a highly effective flame retardant effect, which can effectively prevent the spread of flames and the generation of smoke.

[0026] Reference Figures 2 to 5 The mating kit 5 includes an upper end piece 10, which is used to connect the guide rail 1. The upper end piece 10 is provided with an upper end cavity 11. One end of the guide rail 1 is inserted into the upper end cavity 11, and the inner wall of the upper end cavity 11 is in close contact with the guide rail 1. A spring 7 and an elastic bridge block 8 are also installed at the end of the upper end piece 10 away from the upper end cavity 11. Both ends of the elastic bridge block 8 are fixedly connected to the upper end piece 10, and the spring 7 is located between the elastic bridge blocks 8 and is used to fix the elastic bridge block 8 to the upper end piece 10.

[0027] A mating cavity 6 for inserting the end of the upper end piece 10 is provided at one end of the fixing piece 4 facing the upper end piece 10. At the same time, a plurality of through holes 9 connected to the mating cavity 6 are provided on the fixing piece 4. The number of the through holes 9 is the same as the number of the elastic bridge blocks 8 and is arranged corresponding to the elastic bridge blocks 8.

[0028] After the user inserts the upper end piece 10 into the through hole 9, the spring 7 and the elastic bridge block 8 will also enter the through hole 9 at the same time. Since the opening shape of the matching cavity 6 for inserting the upper end piece 10 is consistent with the shape of the upper end piece 10, after the upper end piece 10 is inserted into the through hole 9, the spring 7 and the elastic bridge block 8 will automatically align with the corresponding through hole 9, and the elastic bridge block 8 will pass through the matching cavity 6 and the through hole 9 under the action of the spring 7, thereby realizing a relatively fixed connection between the guide rail 1 and the end cover 3.

[0029] Reference Figures 2 to 5 The mating kit 5 also includes a lower end piece 13, which is used to connect the rolling roller 2. The lower end piece 13 defines a lower end cavity 14. One end of the rolling roller 2 is inserted into the lower end cavity 14, and the inner wall of the lower end cavity 14 is in close contact with the rolling roller 2. A spring 7 and an elastic bridge block 8 are mounted on the end of the lower end piece 13 away from the lower end cavity 14. Both ends of the elastic bridge block 8 are fixedly connected to the lower end piece 13. The spring 7 is located between the elastic bridge blocks 8 and is used to securely connect the elastic bridge block 8 to the lower end piece 13.

[0030] A mating cavity 6 for inserting the end of the lower end piece 13 is provided at one end of the fixing piece 4 facing the lower end piece 13. At the same time, a plurality of through holes 9 connected to the mating cavity 6 are provided on the fixing piece 4. The number of the through holes 9 is the same as the number of the elastic bridge blocks 8 and is arranged corresponding to the elastic bridge blocks 8.

[0031] After the user inserts the lower end piece 13 into the through hole 9, the spring 7 and the elastic bridge block 8 will also enter the through hole 9 at the same time. Since the opening shape of the matching cavity 6 for inserting the lower end piece 13 is consistent with the shape of the lower end piece 13 and is circular, after the lower end piece 13 is inserted into the through hole 9, the spring 7 and the elastic bridge block 8 will automatically align with the corresponding through hole 9, and the elastic bridge block 8 will pass through the matching cavity 6 and the through hole 9 under the action of the spring 7, thereby realizing a relatively fixed connection between the rolling roller 2 and the end cover 3.

[0032] Reference Figures 2 to 5 The fixing members 4 for connecting the guide rail 1 and the roller blind roller 2 are kept perpendicular to each other, and a connecting block 17 is provided on the side of the two fixing members 4 away from the matching kit 5, and the fixing members 4 are fixedly connected to the connecting block 17.

[0033] A polygonal release member 12 is also mounted on the fixing member 4, which is connected to the guide rail 1. The polygonal release member 12 is in close contact with the outer wall of the fixing member 4 and can slide on the fixing member 4. Before the polygonal release member 12 slides above the through-hole 9, the spring 7 and part of the elastic bridge block 8 are located outside the fixing member 4. To separate the guide rail 1 from the end cover 3, the user only needs to move the polygonal release member 12 above the through-hole 9. The elastic bridge block 8 and spring 7 are compressed toward the fixing member 4 under the pressure of the polygonal release member 12. At this time, the user only needs to pull the fixing member 4 away from the guide rail 1 to separate the fixing member 4 from the guide rail 1.

[0034] A circular release piece 15 is also mounted on the fixing member 4, which is connected to the rolling roller 2. The circular release piece 15 is in close contact with the outer wall of the fixing member 4 and can slide on the fixing member 4. When the circular release piece 15 has not slid above the through-hole 9, the spring 7 and part of the elastic bridge block 8 are located outside the fixing member 4. When the user needs to separate the rolling roller 2 and the end cover 3, they only need to move the circular release piece 15 above the through-hole 9. The elastic bridge block 8 and spring 7 are compressed toward the fixing member 4 under the pressure of the polygonal release piece 12. At this time, the user only needs to pull the fixing member 4 away from the rolling roller 2 to separate the fixing member 4 from the rolling roller 2.

[0035] Reference Figures 2 to 5 A plurality of anti-slip grooves 19 are also provided on the outer surfaces of the circular ejection piece 15 and the polygonal ejection piece 12. Since the user will encounter resistance from the spring 7 and the elastic bridge-shaped piece when pushing the circular ejection piece 15 and the polygonal ejection piece 12, the anti-slip grooves 19 can increase the friction force of the user on the circular ejection piece 15 and the polygonal ejection piece 12, making it easier to push the circular ejection piece 15 and the polygonal ejection piece 12.

[0036] Reference Figures 2 to 5 The mating kit 5 further includes a connecting block 17, which is fixedly connected to the fixing member 4. A magnetic member 18 is also fixedly bonded to the side of the connecting block 17 facing the fixing member 4. The magnetic member 18 can be magnetically connected to the shape-shaped release member and the polygonal release member 12. After the fixing member 4 and the mating kit 5 are combined, the connection between the guide rail 1 and the rolling roller 2 and the end cover member 3 is ensured. In order to prevent the shape-shaped release member and the polygonal release member 12 from shaking freely on the fixing member 4, the user can connect the shape-shaped release member and the polygonal release member 12 through the magnetic member 18.

[0037] A limiting block 16 is fixedly connected to the end of the fixing member 4 away from the connecting block 17, and the limiting block 16 protrudes toward the outer wall of the fixing member 4. Since the circular release member 15 and the polygonal release member 12 are both tightly attached to the fixing member 4, the presence of the limiting block 16 prevents the circular release member 15 and the polygonal release member 12 from detaching from the fixing member 4.

[0038] Reference Figure 6 The connecting block 17 also has a threaded hole 21 extending therethrough. A suction cup 20 is fixedly connected to the opening of the threaded hole 21, and a screw 22 is threadedly connected to the inner thread of the threaded hole 21. When the curtain needs to be installed, after the guide rail 1, the curtain roller 2, and the end cover 3 have been assembled and connected, the guide rail 1 can be glued to the cavity wall, and the user can also connect the end cover 3 to the cavity wall using the suction cup 20. Finally, the guide rail 1, the curtain roller 2, and the end cover 3 are further fixed together using bolts.

[0039] The embodiment of the present application discloses an implementation principle of a flame-retardant curtain end cover: when it is necessary to connect the end cover member 3 with the guide rail 1 and the rolling roller 2, it is only necessary to move the guide rail 1 toward the upper end member 10 and insert it into the upper end cavity 11. At this time, the elastic bridge block 8 will automatically be inserted into the through hole 9, thereby playing a relatively fixed connection between the guide rail 1 and the end cover member 3; if the rolling roller 2 is moved toward the lower end member 13 and inserted into the lower end cavity 14, the elastic bridge block 8 will automatically be inserted into the through hole 9, thereby playing a relatively fixed connection between the rolling roller 2 and the end cover member 3.

[0040] If it is necessary to separate the end cover 3 from the guide rail 1 or the rolling roller 2, it is only necessary to pull the circular separation piece or the polygonal separation piece to retract the spring 7 and the elastic bridge block 8 into the matching cavity 6. Finally, the user can pull the guide rail 1 or the rolling roller 2 to separate them.

[0041] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
