DETAILED DESCRIPTION
[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.
[0028] Please refer to Figures 1-8 The utility model provides an embodiment:
[0029] (1) lower sheath main body and upper sheath main body:
[0030] The lower sheath main body 1 and the upper sheath main body 2 form the sponge mattress placing cavity 14 inside together, for placing the sponge mattress. The two sides and the front end between the lower sheath main body 1 and the upper sheath main body 2 are provided with the three-side slot 3 together, the first half zipper 4 is fixed on the upper end of the lower sheath main body 1 along the lower end of the three-side slot 3 and is stitched, the second half zipper 5 is fixed on the lower end of the upper sheath main body 2 along the upper end of the three-side slot 3 and is stitched, the first half zipper 4 and the second half zipper 5 are engaged by the zipper head 6 and are pulled, the quick opening and closing of the sheath are realized. The user can easily put the mattress into or take out the sheath, and the efficiency of cleaning and replacement is greatly improved.
[0031] (2) Internal limiting unit:
[0032] The internal limiting unit 16 is integrally formed and includes a first edge limiting assembly 17, a second edge limiting assembly 18, a third edge limiting assembly 19, and a fourth edge limiting assembly 20. The first edge limiting assembly 17, the second edge limiting assembly 18, the third edge limiting assembly 19, and the fourth edge limiting assembly 20 are located at the four corners inside the sponge mattress placement cavity 14. The first edge limiting assembly 17 and the second edge limiting assembly 18 are structurally symmetrical, and the third edge limiting assembly 19 and the fourth edge limiting assembly 20 are structurally symmetrical. The first edge limiting assembly 17 and the second edge limiting assembly 18 are equidistantly arranged with the third edge limiting assembly 19 and the fourth edge limiting assembly 20 from top to bottom, and the first edge limiting assembly 17 and the third edge limiting assembly 19 are equidistantly arranged with the second edge limiting assembly 18 and the fourth edge limiting assembly 20 from top to bottom. These limiting assemblies are fixed inside the lower sheath body 1 and the upper sheath body 2 by silk threads, effectively preventing the mattress from sliding. The design of the limiting assemblies makes the mattress more stable during use, avoiding noise and discomfort caused by sliding.
[0033] The first edge limiting assembly 17 and the second edge limiting assembly 18 include a first corner limiting piece 21 and a second corner limiting piece 22 connected by an intermediate connecting piece 23. The first corner limiting piece 21 is located at the two corners of the upper end of the upper sheath body 2, used to block the two corners of the upper end of the mattress. The third edge limiting assembly 19 and the fourth edge limiting assembly 20 include a second corner limiting piece 22 and an intermediate connecting piece 23, and the second corner limiting piece 22 is integrally connected to the lower end of the intermediate connecting piece 23. The second corner limiting piece 22 is located at the four corners of the lower end of the lower sheath body 1, used to block the four corners of the lower end of the mattress. The design of the corner limiting piece further enhances the limiting effect of the mattress, ensuring the stability of the mattress in the sheath.
[0034] (3) Height adjustment structure:
[0035] The first stitched skirt 7 is stitched and fixed at the lower end of the outer periphery of the upper sheath body 2, the third half zipper 8 is stitched and fixed at the lower end of the first stitched skirt 7, and the first plastic inner head 11 is fixed at one end of the third half zipper 8; the second stitched skirt 9 is stitched and fixed at the middle of the outer periphery of the lower sheath body 1, the fourth half zipper 10 is stitched and fixed at the upper end of the second stitched skirt 9, and the second plastic inner head 12 is fixed at the other end of the fourth half zipper 10 corresponding to the first plastic inner head 11 in the vertical direction; the other ends of the third half zipper 8 and the fourth half zipper 10 are jointly stitched and fixed with the limiting edge 13, which is mainly to avoid the zipper puller from being pulled too far and causing tooth loss. When the height of the mattress is relatively small, the first plastic inner head 11 and the second plastic inner head 12 can be passed through the through hole of the zipper puller, so that the third half zipper 8 and the fourth half zipper 10 are closed, thereby reducing the height of the sheath to match the height of the mattress. This height adjustment structure makes the sheath applicable to mattresses of different heights, improving the versatility and practicality of the sheath.
[0036] (4) Lower silica gel limiting point:
[0037] The lower silica gel limiting point 15 is arrayed and fixed at the lower end of the inner periphery of the lower sheath body 1, which is used for preliminarily preventing the sponge mattress from slipping and enhances the anti-slip effect of the mattress, thereby ensuring the stability of the mattress in the sheath.
[0038] Working principle: the first half zipper 4 and the second half zipper 5 are opened by the zipper puller 6, the upper sheath body 2 is pulled apart by the three-edge slot 3, the first edge limiting assembly 17 and the second edge limiting assembly 18 are stretched and deformed by the rotation of the middle connecting piece 23, the lower sheath body 1 and the upper sheath body 2 are separated by three edges, the sponge mattress is placed in the exposed sponge mattress placing cavity 14, and the lower silica gel limiting point 15 preliminarily prevents the sponge mattress from slipping; the sponge mattress is clamped at the four corner positions of the lower end by the second corner limiting piece 22 of the first edge limiting assembly 17, the second edge limiting assembly 18, the third edge limiting assembly 19 and the fourth edge limiting assembly 20, and the first connecting piece 24 and the second connecting piece 25 are located at the lower end positions of the four sides of the sponge mattress.
[0039] The upper sheath body 2 is turned back to the upper end of the sponge mattress, the first edge limiting assembly 17 and the second edge limiting assembly 18 are stretched and deformed vertically by the rotation of the middle connecting piece 23, and the first corner limiting piece 21 of the first edge limiting assembly 17 and the second edge limiting assembly 18 is clamped at the upper two corner positions of the rear end of the sponge mattress; the first half zipper 4 and the second half zipper 5 are pulled up by the zipper puller 6.
[0040] When the height of the sponge mattress is small, the height of the sheath is large, the middle connecting piece 23 on the first edge limiting assembly 17 and the second edge limiting assembly 18 has no vertical stretching deformation space, after the first half zipper 4 and the second half zipper 5 are closed, the through hole of the zipper puller passes through the first plastic inner head 11 and the second plastic inner head 12, so that the third half zipper 8 and the fourth half zipper 10 are closed, the first stitched skirt 7 and the second stitched skirt 9 are connected, and the height of the whole sheath is reduced to match the height of the sponge mattress.
[0041] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.
