DETAILED DESCRIPTION

[0029] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0030] like Figure 1-Figure 9 As shown, the nursing equipment back cushion with good air permeability provided by this embodiment includes a base plate 1, a sponge 2 and a fabric 3. A tensioning wire 4 is horizontally arranged on the inner side of the fabric 3, and an annular groove 5 for accommodating the tensioning wire 4 is arranged on the base plate 1. The tensioning wire 4 is pressed downward and fixed in the annular groove 5 of the base plate 1, so that the sponge 2 and the fabric 3 present a groove structure. When assembling, the sponge 2 is first placed on the base plate 1, and then the fabric 3 is placed on the sponge 2, and then the tensioning wire 4 is pressed downward, and then the tensioning wire 4 is fixed around the back of the base plate 1, and finally the fabric 3 is sewed on the back of the base plate 1 so that the fabric 3 wraps the base plate 1 and the sponge 2.

[0031] In this embodiment, if Figure 1 As shown, two tensioning wires 4 are provided, and the two tensioning wires 4 are evenly distributed along the length direction of the fabric 3, so that the backrest cushion as a whole presents two groove structures, which has a better ventilation effect.

[0032] In this embodiment, if Figure 3 As shown, the front side of the bottom plate 1 is provided with expansion grooves 6 on both sides of the annular groove 5 to provide additional space for the sponge 2 and the fabric 3 squeezed by the tensioning wire 4, so that when the groove is formed, the accumulation of materials will not cause discomfort or affect the appearance.

[0033] In this embodiment, if Figure 5As shown, a fixing groove 7 is provided on the back of the base plate 1, and both sides of the fixing groove 7 are connected with the annular groove 5. A fixing component 8 is provided in the fixing groove 7. Both ends of the tension wire 4 will pass through the annular groove 5 and flow into the fixing groove 7, and be fixed by the fixing component 8 in the fixing groove 7.

[0034] In this embodiment, if Figure 8 and Fig. 9 As shown, the fixing assembly 8 includes a fixing plate 801, fixing holes 802 are arranged on both sides of the fixing plate 801, bolts 803 are arranged in the fixing holes 802, and threaded holes 9 are arranged on the fixing groove 7. The positions of the threaded holes 9 and the fixing holes 802 correspond one to one. The two ends of the tension wire 4 are inserted into the bottom of the fixing plate 801, and then the bolts 803 are tightened to make the fixing plate 801 tightly pressed against the tension wire 4.

[0035] In this embodiment, if Figure 5 As shown, two fixing plates 801 are provided, and the two fixing plates 801 are spaced apart along the length direction of the fixing groove 7 to ensure the fixing effect.

[0036] In this embodiment, if Figure 7 As shown, a tensioning wire groove 10 is provided on the inner side of the fabric 3 for the tensioning wire 4 to pass through, thereby ensuring that the tensioning wire 4 is accurately positioned on the fabric 3 and facilitating the formation of a neat groove structure.

[0037] In this embodiment, if Figure 1 As shown, a plurality of first air holes 11 and a second air hole 12 corresponding to each other are respectively provided on the base plate 1 and the sponge 2. The plurality of first air holes 11 and the second air holes 12 are respectively evenly distributed on the base plate 1 and the sponge 2, providing ventilation channels for the backrest, facilitating air circulation, and significantly improving the air permeability of the backrest.

[0038] In this embodiment, if Figure 1 and Figure 3 As shown, a circular fixing plate 13 is arranged in the first air vent 11 on the bottom plate 1, a spring 14 is arranged on the circular fixing plate 13, and a circular supporting pad 15 is arranged on the spring 14. The spring 14 and the circular supporting pad 15 provide supporting force to prevent the air vent from being sunken and causing discomfort during use. During the design, the circular supporting pad 15 is slightly protruded from the sponge 2, which can also provide a certain massage effect.

[0039] In summary, in this embodiment, the backrest pad of this embodiment is provided with a tension wire 4 on the inner side of the fabric 3. By pressing the tension wire 4 downward, the backrest pad presents a groove structure as a whole, which increases the space for air circulation and effectively improves the air permeability of the backrest pad. The groove structure allows air to flow freely between the user's back and the backrest pad, which helps to reduce the accumulation of heat and moisture, thereby providing a drier and more comfortable use experience; the provided base plate 1 and sponge 2 greatly improve the air circulation through the first air vent 11 and the second air vent 12, and the comfort of the backrest pad is ensured by the spring 14 and the circular support pad 15. The tension wire 4 is accommodated by the annular groove 5, and the squeezed sponge 2 and fabric 3 are accommodated by the expansion groove 6, ensuring that the overall appearance of the backrest pad is neat and tidy after assembly, without any extra protruding parts. This not only enhances the aesthetics of the product, but also improves the safety of use and avoids possible hooking and damage risks.

[0040] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
