[0064] Referring to Figures 1-14, this embodiment provides a mattress cover fixing structure. This mattress cover fixing structure is used to fix the mattress cover 1 on the mattress and form a tight fit to avoid wrinkles and displacement. The flat and fixed mattress cover 1 makes the bed surface look neater and more orderly, improving the overall aesthetics of the bedroom.

[0065] The mattress consists of an elastic module 3, a padding layer 2, and a fitted sheet 1. The elastic module 3 is composed of several spring units 31 spliced ​​together. The padding layer 2 is laid flat on top of the elastic module 3, and the fitted sheet 1 is laid flat on top of the padding layer 2. The spring unit 31 is a spring pocket structure with built-in springs. A waist loop buckle 32 is provided at the waist of the spring unit 31, which refers to the middle position of the spring unit 31. The waist loop buckle 32 constitutes a third connecting member for the splicing of adjacent spring units 31. The waist loop buckle 32 has a snap-fit ​​connection between two pairs of waist loop buckles 32, and the snap-fit ​​connection is a detachable structure.

[0066] The fixing structure between the elastic module 3, the padding layer 2, and the fitted sheet 1 is as follows: the elastic module 3 is composed of several spring units 31, and a waist ring buckle 32 is provided at the waist of the spring unit 31. The waist ring buckle 32 serves as the connecting structure of the elastic module 3. A first connector is provided on the edge of the padding layer 2, and a ring strap 11 is provided on the edge of the fitted sheet 1. The first connector is used to pass through the ring strap 11 and form a buckle connection with the waist ring buckle 32. The padding layer 2 is fixed to the elastic module 3 by the first connector, and the fitted sheet 1 is fixed to the padding layer 2 by the ring strap 11. The connection between the first connector, the ring strap 11, and the third connector constitutes the fitted sheet fixing structure. The padding layer 2 is fixed to the fitted sheet 1 by the first connector.

[0067] The first embodiment is shown in Figures 1-6.

[0068] Several loops 11 are arranged around the circumference of the fitted sheet 1. The mattress padding layer 2 has several first connectors arranged according to the length and width of the mattress. The positions of these first connectors correspond to the positions of the waist loop buckles 32 on the outer periphery of several spring units 31 of the elastic module 3. Each first connector includes a pull strap 21 and a first fastener 22. A locking member 33 is provided on the waist loop buckle 32. The locking member 33 and the first fastener 22 are connected by a snap-fit ​​structure. The pull strap 21 passes through the loop 11 and is fastened to the locking member 33 by the first fastener 2, thereby fixing the loop 11. It should be noted that a second fastener is provided on the waist loop buckle 32. The second fastener can also be fastened to the locking member 33, connecting the waist loop buckles 32 on adjacent spring units 31 together.

[0069] The loops 11 around the fitted sheet 1 are designed to accurately correspond to the pull straps 21 on the mattress layer 2, achieving precise fixation and preventing the fitted sheet 1 from sliding or shifting during use. Through the cooperation of the loops 11 and pull straps 21, the fitted sheet 1 and the mattress layer 2 remain flat, effectively avoiding wrinkles and creases caused by uneven pulling, and keeping the bed surface clean and beautiful.

[0070] The design of the waist ring buckle 32 of the elastic module, together with the first connector, makes the disassembly and replacement of the fitted sheet 1 simple and quick. Users can easily replace the fitted sheet 1, which is convenient for cleaning and maintenance.

[0071] As shown in Figure 4, the pull strap 21 is fixed to the lower edge of the padding layer 2, and the loop strap 11 passes through the pull strap 21 and hangs at the fixed position between the pull strap 21 and the padding layer 2. The pull strap 21 is fastened to the locking piece 33 of the waist ring buckle 32 by the first buckle 22 provided on it. The pull strap 21 pulls the loop strap 11, thereby flattening the fitted sheet 1, so that the fitted sheet 1 is tight and flat on the padding layer 2.

[0072] The locking member 33 includes a plug-in portion 34 and an elastic protrusion 35 disposed on the upper end of the plug-in portion 34. The first fastener 22 includes a socket 23 and a button 24 disposed on the upper end of the socket 23. The socket 23 is provided with a latch 25 at the position of the button 24. When the socket 23 is inserted into the plug-in portion 34 in the insertion direction, the elastic protrusion 35 springs up and locks onto the latch 25, forming a latch connection. When it is necessary to release the latch connection, simply press down the button 24. The button 24 actuates the elastic protrusion 35 to press down and disengage from the latch 25, and the socket 23 can be pulled outward.

[0073] The second embodiment is shown in Figures 7-10.

[0074] A fitted sheet 1 with a edging is provided, the length of which is adapted to the thickness of the mattress layer 2, and is a short edging 12. After being laid on the mattress layer 2, it can cover the sides of the mattress layer 2.

[0075] The loop 11 is placed on the inside of the short edge 12, and is sewn onto the inside of the short edge 12 with a strip of fabric, leaving an opening for the pull strap 21 to pass through. As shown in Figure 8, the pull strap 21 is fixed to the lower edge of the padding layer 2, and the loop 11 is placed on the lower edge of the short edge 12. The pull strap 21 passes through the loop 11 and fixes the loop 11 to the lower edge of the padding layer 2, so that the edge of the fitted sheet 1 will not flip up when in use, and the fitted sheet 1 and the edge are better secured.

[0076] The third embodiment is shown in Figures 11-14.

[0077] A fitted sheet 1 with a rim is provided. The length of the rim is adapted to the thickness of the mattress layer 2 and can cover the elastic module 3. The coverage length extends to the waist ring buckle 32 of the elastic module 3, forming a long rim 13. After the fitted sheet 1 is laid on the mattress layer 2, the long rim 13 can cover the connection between the first connector and the waist ring buckle 32, making the mattress more aesthetically pleasing when in use.

[0078] The loop 11 is placed on the inside of the short edge 12, and is sewn onto the inside of the short edge 12 with a strip of fabric, leaving an opening for the pull strap 21 to pass through. As shown in Figure 8, the pull strap 21 is fixed to the lower edge of the padding layer 2, and the loop 11 is placed on the long edge 13 at the position corresponding to the lower edge of the padding layer 2. The pull strap 21 passes through the loop 11 and fixes the loop 11 to the lower edge of the padding layer 2, so that the edge of the fitted sheet 1 can fit against the periphery of the padding layer 2 when in use, thus better securing the fitted sheet 1 to the edge.

[0079] The fourth embodiment is shown in Figures 15-21.

[0080] This embodiment provides a mattress cover fixing structure. Unlike the previous three embodiments, the spring units 31 in this embodiment are no longer connected to each other by a third connector. Instead, the spring units 31 are arrayed and connected to the base plate 36 to form an elastic module.

[0081] Specifically, the bottom of the spring unit 31 is fixed to the base plate 36 to form an elastic module 3, and the padding layer 2 is laid flat on the elastic module 3; the padding layer 2 includes a first connector, which is used to fix the padding layer 2 to the elastic module 3; the fitted sheet 1 is provided with a ring strap 11 along its edge, which is used to fix the fitted sheet 1 to the padding layer 2; the first connector passes through the ring strap 11 and forms a detachable connection with the base plate 36.

[0082] Specifically, in order to connect the first connector and the base plate 36, the base plate 36 includes a hook 361, and the first connector includes a pull strap 21; the pull strap 21 is hooked to the hook 361 to fix the padding layer 2 to the elastic module 3; the fitted sheet 1 is fixed through the loop strap 11.

[0083] In this embodiment, the fitted sheet 1 includes a circumferential edging 14, which is a continuous, one-piece edging. The edging 14 adopts a short edging design.

[0084] The fifth embodiment is shown in Figures 22-26.

[0085] In this embodiment, in order to connect the first connector and the base plate 36, the base plate 36 includes a socket 361, and the first connector includes a plug block 26.

[0086] The insert 26 passes through the ring band 11 and is inserted through the insertion hole 361 to fix the soft pad layer 2 to the elastic module 3;

[0087] The ring 11 is attached to the insert 26 and the fitted sheet 1 is fixed by the insert 26.

[0088] The difference between this embodiment and the fourth embodiment is that the edging is composed of multiple spaced-apart edgings 15, with a clearance space between adjacent edgings 15; the clearance space can reduce the wrinkles caused by the downward folding of the edgings 15, improving comfort and aesthetics.

[0089] In use, first assemble the base plate 36 and the spring unit 31 to form the elastic module 3, then lay the soft padding layer 2 on the elastic module 3, lay the fitted sheet 1 on top of the soft padding layer 2, and let the edge 15 hang down on the side of the soft padding layer 2. When inserting the plug 26 and the insertion hole 361, first put the loop 11 of the fitted sheet 1 on the plug 26 to form a hanging connection, and then insert the plug 26 one by one into the insertion hole 361 of the base plate 36 to complete the hanging of the fitted sheet 1.
