DETAILED DESCRIPTION OF THE EMBODIMENT

[0028] The technical solutions in the embodiments of the present disclosure will be described clearly and completely in combination with the drawings. Apparently, the described embodiments are only part of the embodiments of the present disclosure, not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary skilled person in the art without making creative labour belong to the protection scope of the present disclosure.

Embodiment 1

[0029] As shown in FIG. 1-FIG. 6, an integrated plastic shell roller skate includes a shoe inner sleeve 1, a plastic shoe shell 2, and a shoe rack assembly. The shoe rack assembly is fixedly installed on the bottom of the plastic shoe shell 2. The shoe inner sleeve 1 is one-step formed in the inner mold, and the plastic shoe shell 2 is one-step formed at the outer side of the shoe inner sleeve 1 through the shoe shell mold, so that the plastic shoe shell 2 and the shoe inner sleeve 1 are formed as a whole. The manufacturing process is as follows: the shoe inner sleeve 1 is put on the inner mold cavity of the shoe shell mold after the forming of the shoe inner sleeve 1 is completed; the plastic shoe shell 2 is one-step formed on the outer side of the shoe inner sleeve 1 by the injection molding of the shoe shell mold, so that the inner surface of the plastic shoe shell 2 and the outer surface of the shoe inner sleeve 1 are closely combined and integrated into one body.

[0030] The shoe inner sleeve 1 is formed into the shape and size of the shoe inner sleeve 1 by one-step pressing in the inner sleeve mold with a cut-piece composite material, including an inner layer, an intermediate layer and an outer layer, and the intermediate layer is made of EVA material.

[0031] The shoe inner sleeve 1 is provided with a positioning structure matched with the inner mold cavity of the shoe shell mold, the positioning structure is an eyelet of the shoe inner sleeve 1, and the shoe shell mold is provided with a small cylinder correspondingly, and the eyelet is sleeved and hung on the small cylinder. Convex and concave parts of the shoe inner sleeve 1 covered from the rear end of the ankle heel part to the front end of the instep are matched with the inner mold cavity of the shoe shell mold to form an inverted buckle. Here, the shoe inner sleeve 1 has a certain elasticity, and the matching design of the eyelet and the shoe shell mold for anti-displacement can effectively ensure that the shoe inner sleeve is not displaced. In addition, the matching inverted buckle clamps the shoe inner sleeve 1 on the inner mold cavity of the shoe shell mold, preventing the shoe inner sleeve from sliding out and loosening.

[0032] The outer side of the shoe edge part of the shoe inner sleeve 1 is made of hard EVA material, and the inner foot sticking part is made of soft EVA material. The shoe inner sleeve 1 is pressed once in the inner sleeve cold pressing die after pre-heating. The inner layer of the shoe inner sleeve 1 is made of microfiber material.

[0033] The upper part of the shoe inner sleeve 1 is provided with a fastening structure, and the fastening structure is provided with an eyelet set for wearing shoelaces, or a fixed Velcro kit. The outer side of the plastic shoe shell 2 is further provided with a leather material with a zipper at the position of the shoe tongue mouth.

[0034] The outer layer of the shoe inner sleeve 1 includes the reinforcing structure 3 hot pressed at the parts connected with the fastening structure and the plastic shoe shell 2, respectively. The reinforcing structure 3 is PU or long fiber material arranged outside the shoe inner sleeve 1.

[0035] The shoe rack component is a roller slide frame 4 and a roller set 5 mounted on roller slide frame, and the roller set 5 includes a plurality of rollers. By using the plastic shoe shell produced by the shoe shell mold with the same size and changing the detachable inserts at the sole position of the plastic shoe mold, the different styles of skates with different base piece and different positions are realized, so as to realize multiple styles in one mold. Namely, the integrated plastic shell ice skates can be produced, and the integrated plastic shell roller skates can also be produced.

[0036] The outer side of the plastic shoe shell 2 is pasted with a leather.

Embodiment 2

[0037] As shown in FIG. 7-FIG. 8, this embodiment is different from embodiment 1 in that it is an integrated plastic shoe shell ice skate, and the shoe rack component is the ice skate blade rack and the ice skate blade 6 installed on it. The bottom of the plastic shoe shell can be assembled into various styles of integrated ice skate shoes by installing different types of the ice skate blade 6 and changing the installation position and method.

[0038] Although the embodiments of the present disclosure have been shown and described, it can be understood to those skilled in the art that a variety of changes, modifications, substitutions and variants can be made to these embodiments without departing from the principle and spirit of the present disclosure, and the scope of the present disclosure is defined by the appended claims and their equivalents.
