Method for firmly fixing connection buckles connecting shoe sole with shoe vamp to inner side edge of shoe sole

Abstract

The invention relates to connection buckles, and provides connection buckles used for connecting a shoe sole with a shoe vamp. The connection buckles are reasonable in structure, and capable of detachably connecting the shoe sole with the shoe vamp, being firmly connected with the surface of the shoe sole and being prevented from being pulled and dropping in the walking process. The connection buckles are arranged on the two sides in the shoe sole in an injection molding mode. The upper surfaces of the connection buckles are provided with open grooves, a connecting clamping buckle is arranged above the side, far away from each open groove, of the corresponding connection buckle, clamping blocks are arranged at the positions, above the two sides in the open grooves, of the connection buckles, the bottom faces of the connection buckles are evenly provided with connecting rods capable of being pressed into the surface of the shoe sole, the free ends of the connecting rods are provided with connecting clamping blocks, and the bottoms of the connecting clamping blocks are provided with tip protrusions, wherein the connecting clamping blocks can be conveniently pressed into the shoe sole during injection molding through the tip protrusions.

Description

technical field [0001] The invention relates to a shoemaking process, in particular to a method for fastening a connecting buckle connecting a shoe sole and a shoe upper to the inner edge of the shoe sole. Background technique [0002] Known shoes are mainly composed of soles and uppers located on the top of the soles. Most of them are made according to traditional techniques and styles. The uppers and soles are fixedly connected, and the uppers cannot be freely replaced according to actual needs. A pair of shoes There can only be one style, it is not targeted, and it cannot bring new ideas to people, especially for children, who need to be involved in various basic knowledge in childhood, exercise children's cognitive and hands-on ability, and identify problems in various things , most of the known shoes can only be used for wearing, and cannot make children interested in their own shoes, and cannot meet the needs of children's cognition. Moreover, when any part of the sol...

Problems solved by technology

But it has following defect in use: 1, each fixed hinge is cemented around the inboard of sole top, because the material of fixed hinge (hard material) and sole (EVA) is different, fixed hinge is bonded on sole surface Unreliable, easy to be pulled and dropped during walking, affecting the use effect and comfort

2. The midsole is only flexibly connected to the sole through rivets and fixing holes, and the lock is not strong, which affects the comfort of use

This invention increases the connection strength between the connecting buckle and the sole by changing the shape of the connecting buckle. During manufacture, each connecting buckle can be directly pressed into the lower part of both sides of the sole through the mold when the bottom line of the sole is hydraulically pressed, and the connecting block at the bottom of the connecting buckle It can be pressed into the inside of the sole through the mold and combined with the sole, so that the connecting buckle can be fixed on the surface of the sole. The top protrusion on the connecting block can facilitate the connecting block to be pressed into the inside of the sole. It is very convenient to press into the sole and fix it on the sole. However, the applicant found that during use, because the materials of the connecting buckle and the sole are different, the connecting buckle is made of hard material, while the sole is made of soft material. Still can’t really be integrated, the connecting buckle still can’t be fixed on the inner side of the sole surface, and it’s still easy to be pulled and dropped during walking, which affects the use effect and comfort, and the market response is not good.
