Abstract

An improved steel head shoes punch fixed structure comprises a shoe body, a steel head and a sole, wherein the front of the shoe body is a covering part, and the rear is a wearing inlet, the bottom of the shoe body is an upper joint, and around the upper joint is provided with a plurality of holes; around the steel head is provided with a plurality of holes; the top of the sole is the lower joint, and around the lower joint is provided with a plurality of salient points in corresponding to the upper joint of the shoe body and the holes on the steel head; when in combination, the steel head is arranged inside the covering part of the shoe body and the holes of both are aligned, and then put into a mould and form the sole through injection molding; in the meantime, the lower joint of the sole is coupled with the corresponding upper joint of the shoe body, the plurality of the salient points around the lower joint of the sole are crowded together into the front covering part of the shoe body, and the holes of the steel head and the holes of the rear upper joint make the steel head, the shoe body and the sole fixed.

Description

The steel toe footwear perforation fixed structure of improvement

Technical field

The utility model relates to a kind of steel toe footwear perforation fixed structure of improvement, especially refer to a kind of fixed structure that steel toe is incorporated into footwear body and sole the place ahead, when sole is made with shoot mode, salient point around the sole can be got into and be positioned over the perforation around the footwear body in the mould, at this moment, steel toe can combine with footwear body and sole easily and fast, and then the tight ness rating after increasing steel toe and footwear body, sole combining.

Background technology

With regard at present known steel toe footwear perforation fixed structure, (as shown in Figure 4), include a footwear body 4, a steel toe 5 and a sole 6; Wherein, these footwear body 4 the place aheads are covering portion 41, and the bottom is last joint mouth 42; Be equipped with several holes 51 on this steel toe 5; This sole 6 is with shoot mode shaping making, and these sole 6 tops are to engage mouth down, can form the periphery of this sole 6 at the periphery of this time joint mouth.

When implementing according to above-mentioned member combination, at first this steel toe 5 is placed in the covering portion 41 of this footwear body 4, pass the hole 51 that ring is established on this steel toe 5 with suture 7 again, allow this steel toe 5 be incorporated in the covering portion 41 of this footwear body 4, last this sole 6 of again injection molding being produced, be connected to going up of this footwear body 4 with the following joint muzzle of this sole 6 and engage outside mouthfuls 42, and fix each other with sticker, the footwear body 4 the place ahead covering portions 41 after allowing this steel toe 5 be positioned at this footwear body 4 and sole 6 combines promptly implement and finish.

By the known as can be known steel toe footwear perforation of above narration fixed structure in the use, it mainly is to pass the hole that ring is established on the steel toe by a suture, and steel toe is incorporated in the covering portion in footwear body the place ahead.Though the mode of sewing up with suture can be fixed on steel toe in the covering portion in footwear body the place ahead, after suture has used of a specified duration, can produce the situation of moth erosion, fracture, so the shortcoming that exists steel toe in the covering portion of footwear body the place ahead, to come off or separate.

In addition, though sole adopts direct plastics injection molding, but owing to engage a mouth peripheral region on following joints of footwear body mouthful and the sole, do not prevent the structure Design of coming unstuck, just fix each other merely, so shoes are once after having used of a specified duration, just be easy to generate the situation of coming unstuck that the footwear body separates with sole with sticker, thereby cause sole to damage easily because of the rainy day is soaked, and have influence on the quality and the life-span of footwear.

Summary of the invention

The present utility model people because the shortcoming that above-mentioned known steel toe footwear perforation fixed structure exists when reality is used be engaged in this cause experience for many years according to the individual, and study intensively, the steel toe footwear of the designing a kind of brand-new improvement fixed structure of boring a hole.

Main purpose of the present utility model, be to provide a kind of steel toe footwear perforation improved fixed structure, it is used to improve after known suture used of a specified duration, can produce the situation of moth erosion, fracture, thus the shortcoming that causes steel toe in the covering portion of footwear body the place ahead, to come off or separate.

Secondary objective of the present utility model, be to provide a kind of steel toe footwear perforation fixed structure of improvement, it is used to improve known footwear body and is not easy to generate the footwear body separates the situation of coming unstuck with sole shortcoming because preventing to come unstuck structure Design with sole after long-term the use.

For achieving the above object, the utility model comprises a footwear body, a steel toe and a sole; Wherein, this footwear body the place ahead is a covering portion, and the rear is for dressing mouthful, and this shoe bottom is last joints mouthful, described go up to engage mouthful be equipped with several perforation on every side; Be equipped with several perforation around this steel toe; The top of this sole engages mouth under being, is provided with around the described mouth of joint down on above-mentioned these footwear bodies of several correspondences and engages the salient point of boring a hole on mouth and this steel toe; During combination, at first allow this steel toe place in the covering portion of this footwear body, and allow perforation each other align, then be placed in the mould, again with injecting glue injection molding sole, simultaneously, the following joint mouth of this sole, can be engaged in and engage outside the mouth on this corresponding footwear body, this sole engages mouthful several salient points that form down on every side, and can get into the perforation that on the perforation of this footwear body the place ahead covering portion and this steel toe and rear, engages mouthful, steel toe and footwear body and sole are fixed, with the steel toe footwear that form the complete improvement fixed structure of boring a hole.

Therefore, the utility model has following improvement in design:

The utility model since footwear body following engage mouthful with sole on engages mouthful periphery be respectively equipped with bore a hole and salient point prevent the structural design of coming unstuck, so by following joint mouthful place's salient point of the formed sole of injection molding mode can get into really, closely around footwear body the place ahead covering portion that is incorporated into, the steel toe with set perforation around the footwear body rear in, make steel toe, footwear body and sole all can firmly combine.

2. because the utility model need be as the mode of commonly using with suture next covering portion and steel toe in conjunction with footwear body the place ahead, and use sticker in conjunction with the upper and lower mouth that engages of footwear body with sole, so can not produce suture because of long duration and produce the situation of moth erosion, fracture, and shoes take place because of having used for a long time that sticker is insecure the situation of coming unstuck that the footwear body separates with sole to occur.

3. because the utility model is with the combination of injection molding mode, steel toe and footwear body and sole are combined, so on the making flow process of whole steel toe footwear, can save the time of many making compared with the mode of the usefulness suture of commonly using the steel toe footwear.
