It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0039] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0040] See appendix Figure 1 - Appendix Figure 11This embodiment discloses a bed sheet fastener, which includes: a protective body 1 and a fastening assembly 2; the protective body 1 includes a base plate 10 and a side plate 11 disposed on the base plate 10, and the side plate 11 is provided with a first external connecting part 111 and a second external connecting part 112; the fastening assembly 2 includes a linkage member 20 and a first plate 21 and a second plate 22 disposed opposite to each other; the first plate 21 is provided with a first connecting part 211 that can be connected to the first external connecting part 111, and the second plate 22 is provided with a second connecting part 222 that can be connected to the second external connecting part 112; the linkage member 20 has a first pivoting part 201 and a second pivoting part. 202, the first pivot 201 is connected to the first plate 21, the second pivot 202 is connected to the second plate 22, and the linkage 20 has a first position and a second position; when the linkage 20 is in the first position, the distance between the first connecting part 211 and the second connecting part 222 is the largest, and the fixing component 2 is separated from the armor body 1; when the linkage 20 is in the second position, the distance between the first connecting part 211 and the second connecting part 222 is the smallest, and the first connecting part 211 is connected to the first external part 111, the second connecting part 222 is connected to the second external part 112, and the fixing component 2 is fixed on the armor body 1.

[0041] Specifically, the side panels 11 are vertically fixed to the base plate 10, forming an L-shaped structure. This allows them to be placed anywhere on the mattress, with the mattress pressing down on the base plate 10, and the side panels 11 fitting against the sides of the mattress. In this embodiment, two side panels 11 can be used, adjacent and perpendicular, thus forming a semi-open, enclosed structure for the protective body 1. In this case, the protective body 1 is mainly used at the four corners of the mattress, with the mattress pressing down on the base plate 10, and the two side panels 11 fitting against two adjacent sides of the mattress. To enhance the stability of the base plate 10 under the mattress, anti-slip textures 100 can be provided on the upper and lower surfaces of the base plate 10, thereby increasing the stability between the base plate 10 and the mattress / base plate 10. The friction between the 0 and the bed board improves the stability of the protective armor body 1 during use; the first external part 111 and the second external part 112 are two connecting structures on the side plate 11 that are far apart from each other. For example, two protrusions can be set on the outer side surface of the side plate 11. In this embodiment, in order to reduce the space occupied by the bed sheet fastener and make the bed sheet fastener thinner, the first external part 111 and the second external part 112 are set as two opposite edges on the side plate 11. Specifically, two opposite edges on the top and bottom of the side plate 11 or two opposite sides on the left and right of the side plate 11 can be selected. In this embodiment, two opposite edges on the top and bottom are preferred in order to achieve a stable clamping effect on multiple positions of the bed sheet.

[0042] To secure the sheet to the mattress, this embodiment includes a detachable fixing component 2. Specifically, before the sheet is laid on the mattress, the protective armor 1 is positioned at a designated location on the mattress. Then, the sheet is laid on the mattress, covering the protective armor 1. At this point, the fixing component 2 is installed on the side panel 11 through the sheet, thus achieving a secure clamping effect on the sheet. Specifically, this embodiment uses a linkage 20 to connect the opposing first plate 21 and second plate 22. The linkage 20 can be a four-bar linkage, a crank-slider mechanism, a parallelogram frame, or other similar mechanisms. As described later in this embodiment, the irregular connecting rod 203a structure allows the first plate 21 to move relative to the second plate 22. Specifically, the first connecting portion 211 on the first plate 21 can move away from or closer to the second connecting portion 222. The maximum distance between the first connecting portion 211 and the second connecting portion 222 is greater than the distance between the first outer portion 111 and the second outer portion 112. In other words, the maximum distance between the first connecting portion 211 and the second connecting portion 222 is greater than the distance between the upper and lower edges of the side plate 11, facilitating the installation of the fixing component 2 on the side plate 11. The minimum distance between the connecting part 211 and the second connecting part 222 is less than or equal to the distance between the first external part 111 and the second external part 112, so as to facilitate the stable assembly of the fixing component 2 onto the side plate 11; by pulling the first plate 21, the linkage 20 can be driven to swing, thereby making the linkage 20 in the first position or the second position respectively. Before use, the fixing component 2 is in a state of being separated from the armor body 1. First, by pulling the first plate 21, the linkage 20 is made to be in the first position, and then the second connecting part 222 on the second plate 22 is connected to the second connecting part 222. The first plate 21 is connected to the second plate 22, and then the first connecting part 211 on the first plate 21 is pulled to move the linkage 20 to the second position. At this time, the first connecting part 211 on the first plate 21 will be connected to the first external connecting part 111. Finally, the first connecting part 211 and the second connecting part 222 are used together to fix the first plate 21 and the second plate 22 to the side plate 11. In actual operation, the user can complete the operation with one hand. The first plate 21 and the second plate 22 are stably connected to the side plate 11 by their own structure. No other tools are needed. The overall structure is simple, the installation method is simple, and the installation is stable.

[0043] In summary, this embodiment achieves stable clamping of the bed sheet by connecting the detachable fixing component 2 to the side plate 11. A linkage component 20 with dual rotation centers is used to connect the first plate 21 and the second plate 22 respectively. By manipulating the first plate 21, the linkage component 20 is positioned in a first position, facilitating the installation of the fixing component 2 on the side plate 11. By manipulating the second plate 22, the linkage component 20 can be moved from the first position to the second position, achieving stable assembly of the fixing component 2 on the side plate 11. The overall structure is simple, and the installation method is easy to operate.

[0044] See appendix Figure 4 Appendix Figure 7 and attached Figure 8 The first connecting part 211 is a first L-shaped buckle plate 211a, and the second connecting part 222 is a second L-shaped buckle plate 222a. The openings of the first L-shaped buckle plate 211a and the second L-shaped buckle plate 222a face each other. Specifically, in this embodiment, the first external connecting part 111 and the second external connecting part 112 are two opposite edges of the side plate 11. In order to achieve the fastening and clamping function of the edges, in this embodiment, the first connecting part 211 is set as the first L-shaped buckle plate 211a, and the second connecting part 222 is set as the second L-shaped buckle plate 222a. Figure 4 The L-shaped slot arrangement shown allows the bottom walls of the first L-shaped buckle plate 211a and the second L-shaped buckle plate 222a to clamp the side plate 11 when the first connecting part 211 and the second connecting part 222 are at their minimum distance. In addition, in this embodiment, the first plate 21 and the second plate 22 are arranged opposite to each other, so that when the linkage member 20 is in the first position, the distance between the first plate 21 and the second plate 22 is large. When the linkage member 20 changes from the first position to the second position, the distance between the first plate 21 and the second plate 22 gradually decreases until the linkage member 20 is in the second position, at which point the first plate 21 is attached to the second plate 22. At this time, the side walls of the first L-shaped buckle plate 211a and the second L-shaped buckle plate 222a are fastened to the side of the side plate 11, thereby improving the stability of the first plate 21 and the second plate 22 on the side plate 11.

[0045] like Figure 3 The bottom ends of the side panel 11 are provided with T-shaped protrusions 110, and the bottom plate 10 is provided with T-shaped slots 101 that connect with the T-shaped protrusions 110. In use, the T-shaped protrusions 110 at the bottom of the side panel 11 are fitted into the T-shaped slots 101 on the bottom plate 10, so that the side panel 11 is stably installed on the bottom plate 10. The detachable method helps the sheet fastener to reduce packaging and transportation costs. In addition, the two T-shaped protrusions 110 are distributed at both ends of the bottom of the side panel 11, so that there is a gap between the bottom edge of the side panel 11 and the bottom plate 10, which facilitates the second L-shaped buckle 222a to be fastened to the edge of the side panel 11 at this point.

[0046] To make the sheet fastener thinner, the second plate 22 has a receiving groove 220. When the linkage 20 is in the second position, the first plate 21 is located in the receiving groove 220, and the first L-shaped fastener 211a and the second L-shaped fastener 222a are symmetrical. The second plate 22 has a handle 223 at the end of the receiving groove 220 away from the second L-shaped fastener 222a. Specifically, the area of ​​the first plate 21 is about half the area of ​​the second plate 22, and the length and width of the first plate 21 are smaller than the receiving groove 220. The length and width dimensions of the groove 220 allow the first plate 21 to be embedded in the receiving groove 220 of the second plate 22. This allows the first plate 21 to be hidden inside the second plate 22 after the sheet fastener clamps and fixes the sheet, resulting in a more aesthetically pleasing and simple overall appearance. Furthermore, the sum of the thicknesses of the second plate 22 and the side plate 11 is the thickness occupied by the sheet fastener on the side of the mattress. In other words, the sheet fastener occupies less space, making the bed look simple and beautiful after the sheet is fixed using this sheet fastener.

[0047] See appendix Figure 10 The rotation axis of the first pivot part 201 of the linkage 20 is parallel to the rotation axis of the second pivot part 202. Specifically, in this embodiment, the first pivot part 201 and the second pivot part 202 are two rotation axes with parallel rotation axes, and the two rotation axes are spaced apart from each other. This allows the distance between the first plate 21 and the second plate 22, and the distance between the first connecting part 211 and the second connecting part 222, to undergo a movement process that changes from large to small and from small to large, thereby fastening the first plate 21 and the second plate 22 to the side plate 1. 1. This completes the fixation of the bed sheet. In this embodiment, the first pivot 201 can be set as the first rotating rod 201a, and the second pivot 202 can be the second rotating rod 202a set at both ends of the first rotating rod 201a. The first rotating rod 201a and the second rotating rod 202a are spaced apart from each other and connected by a connecting rod 203a. In this embodiment, for ease of processing, the linkage 20 is a one-piece metal rod structure. The linkage 20 is processed into the shape shown in the figure through a bending process. Figure 9 The "convex" rod-shaped part shown has a first rotating rod 201a in the middle for hinged connection with the first plate 21, and second rotating rods 202a at both ends for hinged connection with the second plate 22. The linkage 20 has a simple overall structure design. The dual rotation centers allow the first plate 21 to move up and down and back and forth relative to the second plate 22, thereby enabling the first plate 21 and the second plate 22 to be installed on the side plate 11 to complete the pressing and fixing of the bed sheet.

[0048] like Figure 9The first plate 21 has a connecting boss 212, and the connecting boss 212 has a pivot groove 212a. The first rotating rod 201a is rotatably installed in the pivot groove 212a. Specifically, the connecting boss 212 has a strip-shaped structure, and the pivot groove 212a extends along the length of the connecting boss 212, increasing the contact area between the first connecting rod 203a and the connecting boss 212 and improving rotational stability. In addition, the pivot groove 212a adopts an irregular groove structure, with a circular groove at the bottom to facilitate the rotation of the first rotating rod 201a, and a straight groove with an opening width smaller than the diameter of the circular groove to facilitate the first rotating rod 201a to be assembled into the circular groove. It should be noted that the connecting boss 212 in this embodiment is made of plastic. The first rotating rod 201a can be deformed under pressure, thereby installing the first rotating rod 201a in the pivot groove 212a of the connecting boss 212. In order to prevent the first connecting rod 203a from disengaging from the pivot groove 212a during the movement of the linkage 20, the fixing assembly 2 also includes multiple limiting pins 23. The multiple limiting pins 23 are all inserted into the connecting boss 212, and the limiting pins 23 are distributed at the opening of the pivot groove 212a. The multiple limiting pins 23 play a role in limiting the position of the first rotating rod 201a, thereby improving the stability of the overall structure.

[0049] like Figure 6 The second plate 22 is provided with a connecting protrusion 221 that connects to the second rotating rod 202a. The connecting protrusion 221 is provided with a through hole, and the second rotating rod 202a is rotatably installed in the through hole. Specifically, the connecting protrusion 221 is set in the receiving groove 220 of the second plate 22, and the height of the connecting protrusion 221 is less than or equal to the depth of the receiving groove 220, so that when the first plate 21 and the second plate 22 are attached to the side plate 11, the connecting protrusion 221 will not cause interference. In order to allow the first plate 21 to be placed in the receiving groove 220 and to be attached to the bottom wall of the receiving groove 220, this embodiment also provides a clearance hole 213 on the first plate 21 corresponding to the connecting protrusion 221. When the linkage 20 is in the second position, the connecting protrusion 221 is placed in the clearance hole 213, thereby making the overall structure more compact and the sheet fastener thinner.
