[0012] A further preferred technical solution of the present invention is that a plurality of anti-slip teeth are provided on the inner side surface of the second side plate for clamping and cooperating with the two clamping pieces.

[0013] A further preferred technical solution of the present invention is: one end of the rotating connecting piece is connected to the middle part of the control part so that the control part extends from the front and rear sides of the rotating connecting piece, the width of the control part is greater than the width of the clearance hole, and the protrusion is arranged on the rotating connecting piece close to the control part. When the protrusion and the edge of the clearance hole are in a snap-fit ​​state, the control part is located on the outside of the first side panel for hand control.

[0014] A further preferred technical solution of the present invention is: a first clamping surface is formed at the edge of the clearance hole close to one side of the connecting plate, the first clamping surface is inclined from the inner side of the first side plate toward the clearance hole, and a second clamping surface is provided on the raised portion to engage with the first clamping surface.

In this clamping state, the rotating connecting piece is arranged horizontally as a whole, so that the rotating connecting piece has a large elastic force in the longitudinal direction of the first side plate, which is conducive to the protrusion and the edge of the clearance hole to remain in a stable clamping state, and when the quilt is pulled toward the entrance side by force, the quilt acts on the clamping piece to make the rotating connecting piece have a movement tendency to rotate in the clamping direction, thereby avoiding the protrusion and the edge of the clearance hole from being disengaged when the quilt is pulled toward the entrance side.

[0018] In addition, when the two clamping edges cooperate with the second side plate to clamp the quilt stuffed in the space, the two clamping pieces increase the contact area with the quilt, and can clamp it tighter. The free end of one clamping piece is bent toward the side of the connecting plate, and the free end of the other clamping piece is bent toward the side of the inlet. When an external force pulls the quilt toward the side of the inlet, the clamping piece with the free end bent toward the side of the connecting plate will play a role similar to a barb to limit the quilt from moving outward. Similarly, when an external force pulls the quilt toward the side of the connecting plate, the clamping piece with the free end bent toward the side of the inlet will play a role similar to a barb to limit the quilt from moving inward, thereby making the quilt clamped The held quilt is not easy to move relative to the fixer, so as to achieve a more stable clamping effect. When the elastic clamping piece presses down on the quilt for clamping, the clamping piece will be elastically deformed upward under the squeeze, so that it can adapt to quilts of different thicknesses for clamping and fixing, and the two clamping pieces are supported between the rotating connecting piece and the second side plate in a state of being expanded to both sides. The elastic restoring force of the two clamping pieces acts on the middle part of the rotating connecting piece at the same time, so that the two ends of the rotating connecting piece are stretched to both sides, so that the protrusion is clamped more tightly with the edge of the give way hole, and the two expanded clamping pieces can provide more stable support for the rotating connecting piece.

[0032] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0033] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0034] Figures 1-11 As shown, the bed sheet and quilt fastener includes a main body 1 and a clamping member. The clamping member is rotatably connected to the main body 1 and rotates relative to the main body 1 to clamp or release the quilt 24 inserted into the main body 1.

[0035] Figure 7 、 Figure 8As shown, the main body 1 includes a first side panel 2 and a second side panel 4 arranged opposite to each other, and a connecting plate 3 connected between one end of the first side panel 2 and the second side panel 4. A space 10 for accommodating a quilt 24 is formed between the first side panel 2 and the second side panel 4. An entrance 11 for inserting the quilt 24 into the space 10 is formed between the first side panel 2 and the end of the second side panel 4 away from the connecting plate 3. A clearance hole 7 for the clamping member to rotate through is provided on the first side panel 2.

[0036] Preferably, the first side plate 2, the second side plate 4 and the connecting plate 3 constituting the main body 1 are integrally injection-molded by plastic, and the main body 1 is U-shaped.

[0037] The side where the connecting plate 3 is located is defined as the rear side, the side where the inlet 11 is located is defined as the front side, the side where the first side plate 2 is located is defined as the top side, and the side where the second side plate 4 is located is defined as the bottom side.

[0038] Figure 9 、 Figure 10 As shown, the clamping member includes an elastic and arc-shaped rotating connecting piece 8, a control part 6, and two elastic and arc-shaped clamping pieces 9. One end of the rotating connecting piece 8 is rotatably connected to the end of the first side plate 2 away from the connecting plate 3, and the control part 6 is connected to the other end of the rotating connecting piece 8. A protrusion 16 is provided on the rotating connecting piece 8. The rotating connecting piece 8 can be elastically deformed by external force. One end of the two clamping pieces 9 is connected to the middle part of the rotating connecting piece 8, and the other ends of the two clamping pieces 9 are bent in opposite directions.

[0039] Figure 1-Figure 3 As shown, the protrusion 16 can be clamped on the edge of the clearance hole 7 near the connecting plate 3 by elastic deformation and rotation of the rotating connecting piece 8 to form a limit. When the protrusion 16 and the edge of the clearance hole 7 are in a clamping fit, the middle portion of the rotating connecting piece 8 bends and protrudes toward the second side plate 4. The two clamping pieces 9 are located between the rotating connecting piece 8 and the second side plate 4. The free end of the clamping piece 9 located on the inner side is bent toward the side of the connecting plate 3, and the free end of the clamping piece 9 located on the outer side is bent toward the side of the inlet 11. A clamping opening is formed between the clamping piece 9 and the second side plate 4 for clamping the quilt 24 inserted into the space 10. The free end is the end of the clamping piece 9 away from the rotating connecting piece 8.

[0040] Figure 1-Figure 3 、 Figure 11As shown, when the edge of the quilt 24 needs to be clamped and fixed, the edge of the quilt 24 is inserted into the space 10 inside the main body 1 from the entrance 11, and the control part 6 is moved toward the side of the rotation point of the rotating connecting piece 8 to make the rotating connecting piece 8 elastically deformed, and then the rotating connecting piece 8 is rotated downward. The rotating connecting piece 8 drives the protrusion 16 and the two clamping pieces 9 to rotate downward. The two clamping pieces 9 gradually approach the second side plate 4 during the downward rotation process until the protrusion 16 rotates downward to the position below the clearance hole 7. Release the hand that pulls the control part 6, and the rotating connecting piece 8 elastically resets so that the protrusion 16 is stuck on the edge of the clearance hole 7 close to the connecting plate 3 to form a limit. At this time, the clamping opening formed between the two clamping pieces 9 and the second side plate 4 clamps and fixes the quilt 24 inserted into the space 10.

[0041] Figure 5 、 Figure 6 As shown, when it is necessary to remove the edge of the quilt 24 clamped by the fixer, the control part 6 is pushed toward the side of the rotation point of the rotating connecting piece 8 to make the rotating connecting piece elastically deform. At this time, the protrusion 16 and the edge of the side of the clearance hole 7 close to the connecting plate 3 are misaligned and disengaged. Then the rotating connecting piece 8 is rotated upward. The rotating connecting piece 8 drives the protrusion 16 and the two clamping pieces 9 to rotate upward. During the upward rotation process, the two clamping pieces 9 gradually move away from the second side plate 4, so that the clamping mouth opens and the clamped quilt 24 is released until the protrusion 16 rotates to the position above the clearance hole 7, completing the unlocking. At this time, the quilt 24 can be separated from the main body 1 from the entrance 11.

[0042] This patent forms a clamp on the quilt 24 by rotating one end of the arc-shaped rotating connecting piece 8 to the end of the first side panel 2 away from the connecting plate 3, and the protrusion 16 on the rotating connecting piece 8 is engaged with the edge of the side of the clearance hole 7 close to the connecting plate 3. In this clamping state, the rotating connecting piece 8 is arranged horizontally as a whole, so that the rotating connecting piece 8 has a large elastic force in the longitudinal direction of the first side panel 2, which is conducive to the protrusion 16 and the edge of the clearance hole 7 to remain in a stable clamping state, and when the quilt 24 is pulled toward the side of the entrance 11 by force, the quilt 24 acts on the clamping piece 9 to make the rotating connecting piece 8 have a movement tendency to rotate in the clamping direction, thereby avoiding the protrusion 16 and the edge of the clearance hole 7 from being disengaged when the quilt 24 is pulled toward the side of the entrance 11.

[0043] Figure 3As shown, in addition, when the two clamping pieces 9 cooperate with the second side plate 4 to clamp the quilt 24 stuffed into the space 10, the two clamping pieces 9 increase the contact area with the quilt 24, and can be clamped tighter. The free end of one clamping piece 9 is bent toward the side of the connecting plate 3, and the free end of the other clamping piece 9 is bent toward the side of the inlet 11. When an external force pulls the quilt 24 toward the side of the inlet 11, the clamping piece 9 with the free end bent toward the side of the connecting plate 3 will have a barb-like effect to limit the outward movement of the quilt 24. Similarly, when an external force pulls the quilt 24 toward the side of the connecting plate 3, the clamping piece 9 with the free end bent toward the side of the inlet 11 will have a barb-like effect to limit the inward movement of the quilt 24, thereby making it difficult for the clamped quilt 24 to move relative to the fixer, so as to achieve a more stable clamping effect.

[0044] Furthermore, when the elastic clamping pieces 9 press down on the quilt 24 to clamp it, they deform upward under pressure, allowing them to clamp and secure quilts 24 of varying thicknesses. Furthermore, the two clamping pieces 9 are supported between the rotating connecting piece 8 and the second side panel 4 in a state of being extended to the sides. The elastic restoring force of the two clamping pieces 9 simultaneously acts on the middle of the rotating connecting piece 8, causing both ends of the rotating connecting piece 8 to expand to the sides, tightening the protrusion 16 against the edge of the clearance hole 7. The two extended clamping pieces 9 provide more stable support for the rotating connecting piece 8.

[0045] Preferably, the two clamping pieces 9 are arranged in an eight-shaped shape.

[0046] In addition, the second side plate 4 is provided with a plurality of anti-slip teeth 5 on the inner side surface for clamping with the two clamping pieces 9 to achieve a better clamping effect when clamping and fixing the quilt 24, making the clamped quilt 24 more stable and not easy to slide relative to the fixer.

[0047] The first side panel 2 includes a main body 15 and a first curved plate 12. One end of the main body 15 is connected to the connecting plate 3, and one end of the first curved plate 12 is connected to the other end of the main body 15 away from the connecting plate 3. The first curved plate 12 gradually bends toward the second side panel 4 from the end connected to the main body 15 to the other end. One end of the rotating connecting piece 8 is rotatably connected to the inner side of the first curved plate 12. One end of the rotating connecting piece 8 is rotatably connected to the inner side of the first curved plate 12. When the protrusion 16 on the rotating connecting piece 8 engages with the edge of the clearance hole 7 near the connecting plate 3, the support provided by the first curved plate 12 on the end of the rotating connecting piece 8 provides better support strength, thereby ensuring the lateral elastic force of the rotating connector during engagement, thereby making the engagement state more stable.

[0048] Figure 8 、 Figure 9As shown, connecting shafts 14 are fixed on both sides of the end of the rotating connecting piece 8, and two elastic buckle bodies 13 corresponding to the two connecting shafts 14 are fixed on the inner wall of the first arc-shaped plate 12. An axial hole 22 for installing the connecting shaft 14 is formed inside the elastic buckle body 13, and an insertion port 23 for inserting the connecting shaft 14 into the axial hole 22 is provided on one side of the elastic buckle body 13. The width of the insertion port 23 is smaller than the diameter of the connecting shaft 14. The elastic buckle body 13 has elastic edges 21 located on both sides of the insertion port 23 and elastically deformable under force. The elastic edge 21 is elastically deformed by external force, thereby expanding the width of the insertion port 23, so that the connecting shaft 14 can be installed in the axial hole 22 or pulled out from the axial hole 22.

[0049] The main board body 15 is an arc-shaped plate body whose middle part is bent toward the second side plate 4. The end of the clearance hole 7 close to the connecting plate 3 is arranged in the middle of the main board body 15 or on the side of the middle of the main board body 15 close to the connecting plate 3, and the end of the clearance hole 7 away from the connecting plate 3 is arranged at the connection between the first arc plate 12 and the main board body 15, so that the part of the main board body 15 behind the clearance hole 7 gradually bends downward from one end of the connecting plate 3 to one end of the edge of the clearance hole 7. This downward-bending structure enables the protrusion 16 to better support the protrusion 16 when it is stuck on the edge of the side of the clearance hole 7 close to the connecting plate 3, and can guide the protrusion 16 during the downward rotation of the rotating connecting piece 8, guiding the protrusion 16 into the clearance hole 7, which is convenient for user operation.

[0050] Preferably, the first side panel 2 is S-shaped.

[0051] Figure 4 、 Figure 10 As shown, one end of the rotating connecting piece 8 is connected to the middle of the control part 6, so that the control part 6 extends from the front and rear sides of the rotating connecting piece 8. The width of the control part 6 is greater than the width of the clearance hole 7. The protrusion 16 is arranged on the rotating connecting piece 8 near the control part 6. When the protrusion 16 and the edge of the clearance hole 7 are in a snap-fit ​​state, the control part 6 is located on the outside of the first side panel 2 for hand control.

[0052] Figure 3 As shown, a first clamping surface 19 is formed at the lower edge of the clearance hole 7 near the connecting plate 3. The first clamping surface 19 is inclined from the inner side of the first side plate 2 toward the clearance hole 7. The protrusion 16 is provided with a second clamping surface 20 that is engaged with the first clamping surface 19. When the protrusion 16 is rotated to the lower side of the clearance hole 7, the first clamping surface 19 and the second clamping surface 20 are engaged face to face.

[0053] An arc surface 18 is connected between the outer side surface of the first side plate 2 and the first engaging surface 19 . The arc surface 18 can guide the protrusion 16 to the bottom of the first engaging surface 19 to engage when the rotating connecting piece 8 drives the protrusion 16 to rotate downward.

[0054] In addition, the second side plate 4 has an upwardly tilted portion 17 at one end away from the connecting plate 3 . The tilted portion 17 and the edge of the first arc-shaped plate 12 form the inlet 11 .

[0055] This patent is also applicable to the clamping of bed sheets and quilt covers, as well as the sealing of packaging.

[0056] The above describes the sheet and quilt holder provided by the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The above examples are intended only to facilitate understanding of the present invention and its core concept. It should be noted that those skilled in the art may, without departing from the principles of the present invention, make various improvements and modifications to the present invention, and such improvements and modifications fall within the scope of protection of the claims of the present invention.
