Description

Leg guard plate formed by integrally molding and foaming

Technical Field

The utility model belongs to the technical field of sports goods, especially, relate to a leg guard board of integrated into one piece molding foaming.

Background

At present, in leg guard plates on the market, impact-resistant plastic plates (pp plastic plates, TPU, POM, PMMA, ABS, PA, styrene-butadiene rubber plastic plates and other plastic plates) or carbon fiber plates and foam buffer layers (pre-prepared foam buffer layers comprise EVA, XPE, PE, TPE and the like) in the carbon fiber plates are bonded together through double faced adhesive tapes and glue, or the two parts are sewn together through sewing. And adopt glue etc. to paint leg guard board, in process of production, glue smell is big, contains formaldehyde, and the workman is harmful to respiratory track, eyes, skin when laminating, and it is poor that the customer receives the product smelly customer experience simultaneously, and is not environmental protection, and along with the increase of time and frequency of use in the use, the viscous force weakens, drops easily. In the use process of the leg guard plate, the sewing thread is easy to break along with the increase of the use time and the use frequency. In the production process of the plastic board and the buffer layer, the buffer layer needs to be prepared in advance, and then the buffer layer is fixed on the plastic board in a glue adhesion or sewing mode, so that the production efficiency is low. In addition, the pre-prepared foam buffer layer needs to be cut into a required shape according to the shape of the leg guard plate, and a lot of foam buffer layer corner waste materials are generated in the cutting process.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the above-mentioned technical problem that exists among the prior art, provide a fashioned leg guard of integrated into one piece molding foaming, can improve the connection effect and the joint strength between fixed bed and the cotton buffer layer of bubble, be difficult for droing, production efficiency is high simultaneously, practices thrift manufacturing cost, environmental protection more.

In order to solve the technical problem, the utility model discloses a following technical scheme:

an integrally molded and foamed leg guard plate, which is characterized in that: the foam plastic board comprises a fixing layer and a foam buffer layer, wherein the fixing layer and the foam buffer layer are integrally molded and foamed. Through the integrated into one piece foaming shaping, can make do not need glue or sewing to realize the fixed connection between the two between fixed bed and the cotton buffer layer of bubble, fixed effectual, production is convenient, improves production efficiency, and need not tailor the cotton buffer layer of bubble, and it is very few to produce the corner waste material, practices thrift manufacturing cost.

Further, the fixed layer is an arc-shaped fixed plate. Curved fixed plate structure can be convenient for laminate the shank, improves the protective effect of leg guard board, facilitates the use.

Furthermore, the fixing plate is made of plastic or carbon fiber. The fixed plate made of the plastic material is convenient to produce and manufacture, low in cost, high in impact strength of the carbon fiber plate and better in protectiveness, and meanwhile, after the plastic or the carbon fiber material and the polyurethane are molded in a foaming mode, the adhesion fixing effect is good, and the plastic or the carbon fiber material and the polyurethane are not prone to falling off. The plastic material comprises PA, TPU, POM, PMMA, ABS, pp plastic plates, styrene-butadiene rubber plastic plates and other plastic plates.

Furthermore, the material of the foam buffer layer is polyurethane. Compared with the traditional method of preparing a plastic plate and a foam buffer layer in advance and then fixing the plastic plate and the foam buffer layer together, the foam buffer layer foaming-molded foam buffer layer has the advantages that the production efficiency is higher, waste is reduced, and the foam buffer layer and a fixed layer have better adhesion effect and are firmer and difficult to separate.

Furthermore, the foam buffer layer is provided with a ventilating groove, and the ventilating groove can play a role in ventilating and radiating, so that the overall comfort of the leg guard plate is improved.

Further, the foam buffer layer comprises a thin-wall area and a thick-wall area, the thickness of the thick-wall area is larger than that of the thin-wall area, the foam buffer layer is integrally formed through foaming, and the thin-wall area and the thick-wall area with different thicknesses can be manufactured according to the shape of a die according to the use requirement, so that the buffer effect is better during use.

The utility model discloses owing to adopted above-mentioned technical scheme, following beneficial effect has:

the utility model discloses a with fixed bed and the cotton buffer layer integrated into one piece foaming shaping of bubble, can make fixed bed and foaming layer adhesion effect better, need not tailor the cotton buffer layer of bubble in process of production, only produce less leftover bits when the product deburring. The utility model discloses can improve the connection effect and the joint strength between fixed bed and the cotton buffer layer of bubble, be difficult for droing, production efficiency is high simultaneously, practices thrift manufacturing cost.
