Description

Technical Field

[0001] This utility model relates to the field of bedding technology, specifically to a duvet cover with a combination of anti-runaway positioning buckles. Background Technology

[0002] In daily life, duvet covers are a common bedding item used to wrap quilts, and their comfort and practicality have always been the focus of consumers. Currently, traditional duvet covers on the market generally have a significant defect: the quilt is prone to shifting inside the duvet cover, especially during sleep at night or during daily use. The quilt will move and pile up inside the duvet cover, causing the four corners of the duvet cover to be empty and the middle part to become thinner. This not only affects the neatness and appearance of the bed, but also reduces the warmth retention effect, and may even affect the quality of sleep due to local overheating or overcooling.

[0003] To address this issue, some improvements have emerged in existing technologies. Some products use a method of sewing a fixing rope inside the duvet cover to tie the four corners of the duvet tightly. However, this method is cumbersome, and the duvet cover needs to be re-tied every time it is removed and washed. In addition, the rope is prone to tangling and knotting, resulting in a poor user experience.

[0004] Some products use Velcro on duvet covers and quilts for fastening, but the adhesive strength of Velcro weakens after long-term use, reducing its securing effect. In addition, the burrs of Velcro can easily snag on the quilt fabric, causing damage.

[0005] Furthermore, some positioning buckle structures are complex in design, inconvenient to install and disassemble, and cannot adapt to quilts of different thicknesses and materials, thus limiting their practicality. Therefore, developing a quilt cover with a simple structure, good fixing effect, convenient use, and no damage to the quilt core that prevents the quilt from shifting is of significant practical importance.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-3 This utility model provides a technical solution: a duvet cover with anti-running positioning buckles, including a duvet core 1 and a duvet cover 10 covering the duvet core 1. The outer side of the duvet cover 10 is provided with a U-shaped positioning buckle 2 for anti-running operation of the duvet core 1. The U-shaped positioning buckle 2 is provided with an inner fixing groove 20 with an opening, so that the duvet core 1 and the duvet cover 10 can be embedded therein. A protruding post 23 is rotatably connected to the top plate of the U-shaped positioning buckle 2. A vertically arranged stud 25 is fixedly installed at the bottom end of the protruding post 23. A threaded sleeve 26 is threadedly connected to the stud 25. An anti-slip rubber pressing pad 261 is fixedly installed at the bottom end of the threaded sleeve 26. The anti-slip rubber pressing pad 261 presses the duvet core 1 and the duvet cover 10 tightly on the bottom plate of the U-shaped positioning buckle 2, effectively preventing the duvet core 1 from sliding and shifting inside the duvet cover 10.

[0030] In this embodiment, the cross-section of the U-shaped positioning buckle 2 is U-shaped, and each corner of the U-shaped positioning buckle 2 is provided with an arc-shaped corner 21, which makes the originally sharp corner of the U-shaped positioning buckle 2 rounded. During use, whether it comes into contact with the human body or a quilt, it can effectively avoid scratches or wear caused by sharp corners, thus improving the safety and comfort of use.

[0031] like Figure 2 As shown, the top plate of the U-shaped positioning buckle 2 is provided with a through hole 22, and the protruding post 23 is located in the through hole 22 and is rotatably connected to the through hole 22, so that the protruding post 23 can be smoothly installed on the top plate of the U-shaped positioning buckle 2 and achieve rotatable connection, providing a basis for the rotation adjustment of the stud 25 and the threaded sleeve 26, and ensuring that the entire positioning buckle structure can normally perform the function of pressing and fixing.

[0032] like Figure 2 As shown, an annular groove 221 is provided on the wall of the through hole 22, and a protruding ring 24 is fixedly installed on the annular side of the protruding post 23. The protruding ring 24 is located in the annular groove 221 and is rotatably connected to the annular groove 221. The outer diameter of the protruding ring 24 is larger than the outer diameter of the protruding post 23. The size of the protruding ring 24 is adapted to the size of the annular groove 221, so that when the protruding post 23 rotates in the through hole 22, the protruding ring 24 can rotate synchronously in the annular groove 221. This restricts the axial movement of the protruding post 23 during rotation, enhances the stability of the protruding post 23 during rotation, avoids wobbling and deviation, and ensures that the threaded sleeve 26 can be stably adjusted.

[0033] like Figure 2 As shown, two symmetrical guide rods 28 are fixedly installed on the bottom surface of the top plate of the U-shaped positioning buckle 2. Two symmetrical guide grooves 29 are provided inside the threaded sleeve 26. The guide rods 28 are located in the guide grooves 29 and are slidably connected to the guide grooves 29. This allows the guide rods 28 to slide in the guide grooves 29 during the up and down movement of the threaded sleeve 26, providing precise motion guidance for the threaded sleeve 26. This effectively prevents the threaded sleeve 26 from tilting or jamming when moving vertically, and allows the threaded sleeve 26 to drive the anti-slip rubber pressure pad 261 to perform pressing and releasing operations more smoothly.

[0034] like Figure 3 As shown, a key groove 231 is provided on the top surface of the protrusion 23. The protrusion 23 is rotated by the corresponding key 27. Compared with direct operation by hand, the rotation of the threaded sleeve 26 is not only less labor-intensive, but also allows for more precise control of the number of rotations of the threaded sleeve 26. This enables precise control of the pressure of the anti-slip rubber pressing pad 261, facilitating adjustment according to the different thicknesses of the quilt core 1 and quilt cover 10.

[0035] like Figure 3As shown, the key 27 includes a cross-shaped locking block 271 that engages with the key slot 231. A handle 272 is fixedly mounted on the top surface of the cross-shaped locking block 271. Anti-slip stripes 273 are provided on the side of the handle 272. The cross-shaped locking block 271 can be tightly engaged with the key slot 231, providing sufficient torque to drive the protrusion 23 to rotate. The handle 272 is convenient for users to hold and operate, and the anti-slip stripes 273 increase the friction between the hand and the handle 272, making it less likely to slip when turning the key 27, thus improving the convenience and stability of operation.

[0036] When using the anti-runaway quilt positioning buckle combination of this utility model, first insert the quilt core 1 into the quilt cover 10, smooth it out, align the opening of the inner fixing groove 20 on the U-shaped positioning buckle 2 with the corners of the quilt cover 10 and the quilt core 1, and insert the corners into the inner fixing groove 20.

[0037] Take out key 27, insert cross-shaped locking block 271 into key slot 231 on top surface of protrusion 23, hold handle 272 and turn key 27 clockwise to rotate protrusion 23. The stud 25 at the bottom of protrusion 23 will rotate accordingly. Due to the sliding fit between guide rod 28 and guide groove 29, threaded sleeve 26 moves downward along stud 25, causing anti-slip rubber pressing pad 261 to gradually press down, pressing quilt cover 10 and quilt core 1 tightly onto the bottom plate of U-shaped positioning buckle 2.

[0038] When disassembly is required, insert key 27 into key slot 231 and turn counterclockwise. The threaded sleeve 26 will cause the anti-slip rubber pressure pad 261 to rise, releasing the pressure on the duvet cover 10 and duvet core 1. The duvet core 1 can then be easily removed from the duvet cover 10. Throughout the entire use, the arc corner 21 of the U-shaped positioning buckle 2 can effectively prevent scratches to the human body or the duvet. The cooperation between the annular groove 221 and the convex ring 24 ensures that the convex post 23 rotates stably, thereby ensuring that the positioning buckle firmly fixes the duvet core 1.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
