Moreover, the terms first, second, etc. are only used to distinguish a plurality of components or structures having the same or similar structure, and do not denote any particular limitation on the arrangement order or connection relationship.

Referring to fig. 1 to 8, in one aspect, a sheet fixing device 100 is provided, which includes a sheet fixing member 1 and an elastic band connecting structure 2. The bed sheet fixing piece 1 comprises a bottom buckle 3 and a pressing buckle 4, wherein the bottom buckle 3 is integrally in a round cover shape, and a clamping hole a is formed in the round end face of the bottom buckle; of course, in other embodiments, the shape of the bottom buckle 3 is not limited thereto, and may be square as a whole, and one end thereof is provided with a clamping hole a, which is not particularly limited herein. One end of the press buckle 4 is provided with a clamping convex 41, and the other end is provided with a first connecting part; the clamping holes a and the clamping protrusions 41 are clamped and matched to clamp a bed sheet (not shown in the figure). One end of the elastic belt connecting structure 2 is provided with an elastic belt connecting hole h, and the other end of the elastic belt connecting structure is provided with a second connecting part which is detachably connected with the first connecting part; the elastic band connection hole h is used for connection of an end portion of an elastic band (not shown in the drawing) and the elastic band connection structure 2.

In this way, the sheet fixing device 100 is clamped and matched by the bottom buckle 3 with the clamping hole a and the press buckle 4 with the clamping protrusion 41, so that the sheet fixing device can be positioned at any position on the periphery of the sheet, and the sheet is conveniently and stably positioned relative to a mattress (not shown in the figure). Specifically, the sheet fixing device 100 is used in the following steps:

Firstly, fixing at least two sheet fixing devices 100 at two opposite or adjacent sheet peripheral positions of a sheet respectively through sheet fixing pieces 1, specifically, positioning a bottom buckle 3 and a pressing buckle 4 at two sides of the same position of the sheet respectively, and pressing the bottom buckle 3 and the pressing buckle 4, so that the sheet is clamped and positioned by the pressing bottom buckle 3 and the pressing buckle 4; secondly, the elastic belt of the elastic belt connecting structure 2 with the elastic belt is wound around the bottom of the mattress and is connected with the corresponding bed sheet fixing piece 1 in an assembling way, so that the bed sheet can be fixed on the mattress.

Because the sheet fixing device 100 is clamped and matched by the bottom buckle 3 with the clamping hole a and the press buckle 4 with the clamping convex 41, compared with the prior art, the sheet fixing device is used for fixing the sheet by the clamp with the anti-slip claw, and the sheet is not easy to damage when the sheet is stretched and fixed; in addition, the bed sheet fixing device 100 is detachably connected with the bed sheet fixing piece 1 through the elastic belt connecting structure 2, so that the elastic belt and the bed sheet fixing piece 1 can be quickly disassembled and assembled, and the bed sheet fixing device 100 can conveniently fix the bed sheet.

In order to achieve the detachable connection between the bed sheet fixing member 1 and the elastic belt connecting structure 2, optionally, referring to fig. 4, 6 and 8, in this embodiment, the first connecting portion is a hook 44 formed by extending and bending from the press buckle 4; the second connecting portion includes a bayonet i into which the hook 44 can be hung, and a latch 21 disposed in the bayonet i for elastically abutting against the hook 44. Specifically, the side section of the hook 44 is in an L shape, the end section of the hook 44 is semicircular, and a semicircular clamping hole d is arranged at the position of the press buckle 4 corresponding to the semicircular end of the hook 44; the thickness of the latch 21 gradually decreases from the fixed end to the free end. Thus, when the elastic belt connecting structure 2 is hung in the hook 44, the latch 21 can generate certain elastic deformation and abut against the lower end face of the extending end of the hook 44, so as to prevent abnormal separation of the elastic belt connecting structure 2 and the bed sheet fixing piece 1. When the elastic band connecting structure 2 and the bed sheet fixing piece 1 are required to be separated, the bayonet i can be separated from the hook 44 only by outwards snapping the elastic band connecting structure 2 to enable the hook 44 to generate certain elastic deformation. Of course, in other embodiments, the first connecting portion may be a threaded hole with internal threads, and the second connecting portion may be a stud with external threads, so that the elastic band connecting structure 2 and the bed sheet fixing member 1 are detachably connected through threaded connection; of course, the elastic band connecting structure 2 and the bed sheet fixing member 1 may be detachably connected by using a snap fit, which is not particularly limited herein.

In order to enable the bottom buckle 3 and the press buckle 4 to clamp the sheet, optionally, referring to fig. 3, 6 and 7, in this embodiment, the clamping hole a and/or the clamping protrusion 41 have elasticity, so that the clamping hole a and the clamping protrusion 41 are elastically clamped and matched to clamp the sheet. Specifically, the locking protrusion 41 includes a cylindrical connecting post 42 extending outwards from the press buckle 4, and a truncated cone-shaped locking crown 43 connected with the connecting post 42; in order to smoothly clamp the clamping crown 43 into the clamping hole a, the connecting edges of the upper end face and the side face of the clamping crown 43 are rounded, and a plurality of first cutting grooves b communicated with the clamping hole a are uniformly arranged at intervals around the clamping hole a by the bottom buckle 3. Therefore, the clamping hole a can be elastically expanded and restored to the original size, namely, when the clamping crown 43 extrudes the edge of the clamping hole a, the circular end face plates surrounding the clamping hole a are separated into a plurality of discontinuous plates through the first cutting groove b, so that the clamping crown 43 can be elastically deformed to the other side better under the extrusion of the clamping crown 43, and after the clamping crown 43 passes through the clamping hole a, the plates surrounding the clamping hole a can be restored to the original size to clamp the clamping crown 43. Preferably, the bottom buckle 3 is provided with a plurality of arc waist-shaped holes c at equal intervals around the clamping hole a; the first cutting groove b is positioned between two adjacent arc waist-shaped holes c; thus, the elastic expansion of the clip hole a can be better realized. Of course, alternatively, referring to fig. 3, 4, 6 and 7, in the present embodiment, the inside of the locking protrusion 41 is provided with a cylindrical hole e, and the periphery of the locking crown 43 is uniformly provided with a plurality of second slots f. Thus, the catching convex 41 can be made elastic. That is, when the clamping hole a is pressed, the clamping protrusion 41 can be elastically deformed inwards to pass through the clamping hole a, and after passing through the clamping hole a, the clamping protrusion is restored to the original size under the action of elastic restoring force. Further, the bottom buckle 3 and the press buckle 4 are made of a material with certain elasticity, such as elastomer plastic.

Optionally, referring to fig. 4, in this embodiment, an annular boss 45 is formed at an end of the press buckle 4 facing away from the clip protrusion 41, and the press buckle 4 further includes a circular decorative cover 47 covering the annular boss 45. Further, in order to improve the closing stability of the circular decorative cover 47 and the annular boss 45, a plurality of engaging protrusions 46 are uniformly arranged at intervals on the top surface of the annular boss 45, and a plurality of engaging grooves (not shown in the figure) which are matched with the engaging protrusions 46 are correspondingly formed on the inner surface of the circular decorative cover 47.

In order to increase the utilization rate of the sheet fixing device 100, after the elastic belt connecting structure 2 is lost, the sheet fixing device 100 is still used to fix the sheet, optionally, referring to fig. 4, in this embodiment, a bandage connecting hole g is provided at an end of the press buckle 4 away from the clip protrusion 41. In this way, even if the elastic band connecting structure 2 is not used, the fixation of the sheet can be achieved by connecting the bandage (not shown in the drawing) or the elastic band through the bandage connecting hole g.

Another aspect of the present embodiment provides a sheet holder comprising at least two sheet fixing devices 100 as described above, and an elastic band coupled to the elastic band coupling hole h. Since the sheet holder has all the structures and connection relationships of the sheet holder 100, it has all the advantages of the sheet holder 100, which are not described in detail herein.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application, and not for limiting the same; although the application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the corresponding technical solutions.
