Description

Technical Field

[0001] The utility model relates to the technical field of foam insoles, in particular to a polyurethane foam insole. Background Art

[0002] Polyurethane foam insoles are a high-quality insole material with good softness and compression resistance. They can effectively relieve the impact on the soles of the feet when walking and provide a comfortable wearing experience. In addition, polyurethane foam has good breathability, which helps keep the feet dry and reduces the generation of odor. Its lightness also makes the insole easy to clean and replace. It is widely used in various types of shoes, especially in environments where people stand or walk for a long time.

[0003] Existing polyurethane foam insoles are made of polyurethane foam, and when the insoles are used for a long time, they are prone to become deflated and flattened due to long-term stepping on. The deflated and flattened insoles will lose a certain cushioning effect, thereby reducing the comfort of the user and making it inconvenient to wear the polyurethane foam insoles for a long time. For this reason, we propose a polyurethane foam insole. Utility Model Content

[0004] The utility model aims to provide a polyurethane foam insole to solve the problem of the insole becoming deflated and flattened due to long-term stepping on, as mentioned in the background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a polyurethane foam insole, comprising:

[0006] A body, wherein a Velcro is provided on the top of the body, and a groove is provided on the side wall of the body;

[0007] Cover sheet 1, the cover sheet 1 is matched with the top of the body, the cover sheet 1 is provided with breathable gauze inside, a patch is provided on one side wall of the cover sheet, the top of the body is matched with cover sheet 2, the top of the body is embedded with a foam sheet, and the top of the foam sheet is embedded with a plurality of airbag strips;

[0008] The cloth strip is arranged on the top of the main body, the side wall of the cloth strip is provided with a plastic strip, the bottom of the plastic strip is provided with a support piece, and the bottom of the support piece is provided with a plastic piece.

[0009] Preferably, the patch fits inside the groove.

[0010] Preferably, the plastic part is embedded in the top of the body.

[0011] Preferably, both ends of the plastic strip are fixed to the body.

[0012] Preferably, the plastic strip has an arc-shaped structure.

[0013] Preferably, a plurality of deformation grooves are formed on the outer side of the support member.

[0014] Preferably, the cloth strip is fitted to the top of the support member.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. In the present utility model, a first cover sheet and a second cover sheet are arranged on the top of the main body. The first cover sheet and the second cover sheet are attached to the main body by using magic tape and are pasted by using patches. When the foam insole is flattened after being stepped on for a long time, the first cover sheet and the second cover sheet can be torn off to take out the foam sheet for replacement, so that the flattened foam sheet can be replaced, the service life of the polyurethane foam insole is prolonged, and the structure is simple and the replacement operation of the foam sheet is relatively convenient.

[0017] 2. In the present utility model, a plastic strip arched upward is arranged on the top of the main body. When the polyurethane foam insole is used, the arched plastic strip and the support member can be used to support the arch of the foot, which can help disperse the foot pressure, provide additional support and improve the comfort of the polyurethane foam insole during use.
