Description

Detachable expands shoes ware

Technical Field

The utility model belongs to the technical field of shoe nursing tools, and particularly relates to a detachable shoe expander which is used for expanding the space in a finished shoe.

Background

The shoes are foot clothes with decorative and sanitary functions which are worn for protecting feet from being hurt by hard objects such as ribs, spines and the like, and are convenient for walking, protecting against cold and preventing freezing. With the progress of society, the requirements of people on physical life are higher and higher, various styles of shoes made of materials such as cloth, silk or leather are diversified, except a few shoes customized according to specific foot types of people, most of shoes worn by people in daily life are finished shoes made by shoe factories according to the existing shoe tree models, and the finished shoes bought by people only have the code number matching and cannot meet the wearing comfort.

The shoes are different from one another, the foot types of people are more various, and the shoes of the same series are manufactured according to a certain mould, so that a part of the produced shoes are not fit with feet, which can cause the problems of foot grinding, foot squeezing, foot clamping and even change of the original foot types of people, and the problems are particularly prominent in the wearing process of high-heeled shoes; in addition, the discomfort of the shoes inevitably causes frequent exchange or purchase of the shoes, which wastes a lot of time and money and is not economical from the social point of view, and thus, the shoe expander for expanding the space in the finished shoes is produced.

For people with wider feet, the width of the inside of the shoe can be properly widened through the shoe expander; for people with high arch height, the height of the vamp can be properly increased through the shoe expander; for the shoes which are easy to grind heels, the heels of the shoes can be slightly turned outwards by the shoe expander, or the width of the heels is widened, so that the uncomfortable feeling of the feet is reduced.

In the mainstream shoe expanding device in the prior art, for example: patent CN2015207475923 discloses an adjustable shoe expander; patent CN2015207333797 discloses a shoe expander; patent CN2016210840471 discloses a multifunctional shoe expander. The technical scheme of the shoe expander disclosed above achieves the purpose of expanding the space in the finished shoe to a certain extent, but still has some defects, such as:

(1) the shoe types adapted by the existing shoe expanding device are limited;

(2) the existing shoe expander needs to be used according to the corresponding shoe size, and has poor universality;

(3) expansion on demand is difficult to achieve; such as: when expanding the inner width of the shoe, the width or length of the heel of the shoe has to be expanded at the same time; if the user only needs to expand the left width and the right width of the shoe, and the shoe expander simultaneously pushes against the heel, the shoe expander has to be stressed and expanded, and the shaped shoe can be loosened to different degrees;

(4) the front end of each shoe expander is fixed in size and can only expand towards two sides, if the height inside the shoe is required to be increased, the shoe expanders need to be pushed into the shoe with great force, the internal structure of the shoe can be damaged, and the shoe can be even scrapped;

(5) for some pointed leather shoes or pointed shoes, the existing expander cannot meet the requirement of heightening the vamp and cannot meet the requirement of users with higher foot shapes;

(6) the existing shoe expanding devices cannot be suitable for high-upper shoes and boot boots.
