Description

Technical Field

[0001] This utility model relates to the field of home furnishing technology, specifically a retractable bed sheet that can be adapted to different bed types. Background Technology

[0002] Bed sheets are an indispensable household item in people's daily lives, used to lay on mattresses to keep them clean and improve sleep comfort. However, most bed sheets on the market are of fixed sizes and can only fit specific bed types.

[0003] Based on the above, the inventors have discovered the following problems: Different families have significantly different bed types, and their lengths vary. When people change their beds or need to use sheets on different bed types, existing fixed-size sheets are difficult to fit, often requiring the purchase of new sheets of the appropriate size. This not only increases the user's financial cost but may also lead to an excessive number of unused sheets, resulting in resource waste. Furthermore, even for the same bed type, mattresses from different brands may vary in thickness. Existing sheets typically use a simple wrapping design at the edges, which is difficult to securely hold onto thicker mattresses, making them prone to slipping or shifting during use, thus affecting the user experience.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a retractable bed sheet that can be adapted to different bed types, in order to achieve a more practical value. Utility Model Content

A bed sheet body is fixedly connected to the outer side of the take-up roller. One end of the bed sheet body is connected to the pressure plate. An adjustment mechanism for rotating the rotating shaft is provided inside one of the retainers. The adjustment mechanism includes an adjustment shaft. Both ends of the adjustment shaft are rotatably connected to the inner sides of one of the retainers. One end of the adjustment shaft passes through the outer side of one of the retainers. A worm gear is fitted on the outer side of the adjustment shaft. A worm wheel is fitted on the outer side of one end of the rotating shaft. The worm wheel and the worm gear mesh.

[0008] Furthermore, a rocker arm is fixedly mounted on one end of the adjusting shaft, and a crank handle is rotatably connected to the bottom side of the rocker arm.

[0009] The beneficial effect of adopting the above-mentioned further solution is that by adjusting the handle and crank at one end of the shaft, it is convenient to manually rotate the adjusting shaft to achieve convenient adjustment of the length of the bed sheet body, which is labor-saving and flexible.

[0010] Furthermore, a handle cover is fitted onto the outer side of the crank handle, and the outer side of the handle cover has several anti-slip grooves. The beneficial effect of adopting the above-mentioned further solution is that, through the handle cover and anti-slip grooves on the outer side of the crank handle, the friction between the hand and the crank handle is increased, achieving an anti-slip effect when gripping, and improving the stability and comfort of operation.

[0011] Furthermore, the four corners of the pressure plate are all rounded.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the rounded shape of the four corners of the pressure plate avoids damage caused by sharp edges and corners, thus achieving safety protection during use and improving product safety.

[0013] Furthermore, a plurality of first reinforcing ribs are installed at the top of the pressure plate, and the plurality of first reinforcing ribs are distributed at equal intervals.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the structural strength and load-bearing capacity of the pressure plate are enhanced by several first reinforcing ribs at the top of the pressure plate, thereby improving the stability of the pressure plate and extending its service life.

[0015] Furthermore, a plurality of second reinforcing ribs are installed on the inner side of the pressure frame, and the plurality of second reinforcing ribs are distributed at equal intervals.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the structural rigidity of the pressure frame is improved by the presence of several second reinforcing ribs on the inner side of the pressure frame, thus preventing deformation of the pressure frame and achieving a stable pressing effect on the bed sheet body.

[0017] Furthermore, the pressure frame is L-shaped.

[0018] The beneficial effect of adopting the above-mentioned further solution is that, through the "L"-shaped pressure frame, it can better fit the edge of the bed frame, effectively fix the end of the bed sheet body, and ensure that the bed sheet is flat and does not slip when in use.

The rotating shaft is adjusted through the meshing transmission of the adjusting shaft, worm gear, and worm wheel in the adjusting mechanism, thereby controlling the unfolding and retracting of the bed sheet body by the winding roller. The pressure frame presses one end of the bed sheet body to ensure the flatness of the unfolded bed sheet. The crank handle and crank arm at one end of the adjusting shaft allow for convenient manual rotation of the adjusting shaft, enabling easy adjustment of the unfolded and retracted length of the bed sheet body. The operation is effortless and flexible. The handle sleeve and anti-slip groove on the outside of the crank arm increase the friction between the hand and the crank arm, achieving an anti-slip effect when gripping. This invention improves operational stability and comfort. The rounded corners of the pressure plate prevent sharp edges from causing damage, ensuring safety during use and enhancing product safety. Several first reinforcing ribs at the top of the pressure plate enhance its structural strength and load-bearing capacity, improving stability and extending service life. Several second reinforcing ribs on the inner side of the pressure frame increase its structural rigidity, preventing deformation and ensuring stable compression of the bed sheet. The "L"-shaped pressure frame better conforms to the bed frame edges, effectively fixing the ends of the bed sheet and ensuring it remains flat and doesn't slip during use. This invention effectively adapts to different bed sizes, has high versatility, and possesses significant practical value. Attached Figure Description
