Description

It is a kind of from skinning saddle

Technical field

The utility model belongs to bicycle art, more particularly, to one kind from skinning saddle.

Background technology

At present, existing bicycle saddle on the market typically adds PU polyurethane foamings to add leather and people using plastics drain pan The production technology of the operating type of work envelope, this technique need a large amount of artificial time length for carrying out envelope work, not only needing, And workload is big, such a saddle mode of production is not easy production and complex process, while strict to mould tool technological requirement, not only Production cost is higher, and yields is relatively low.Need to be improved this production technology, to reduce production cost.

The content of the invention

Problem to be solved in the utility model is to provide one kind from skinning saddle, is related to bicycle saddle, is adapted to voluntarily Car saddle uses, and for saddle cushion using being integrally formed from skinning technology mode, process is simple, easy for installation.

In order to solve the above technical problems, the technical solution adopted in the utility model is：It is a kind of from skinning saddle, including saddle Main body, saddle main body include drain pan and cushion layer, and cushion layer and drain pan are by from skinning injection moulding integrated molding, the lower surface of drain pan Screwed hole is equipped with, and drain pan rear end screwed hole is symmetrical set.

Further, in addition to screw, screw are located on drain pan by screwed hole.

Further, side of the drain pan away from cushion layer is provided with circular groove, circular groove and screwed hole concentric.

Further, cushion layer upper surface is provided with anti-skidding Argyle.

The utility model has the advantages and positive effects of：Due to using above-mentioned technical proposal, using to plastics drain pan Sealing, prevents plastics drain pan material leakage, increases edge strength, toward mold cavity within injection molding technique, can so reduce Manual work, from type and wear-resisting is formed, service life can extend foam surface than common process；External form can arbitrarily make, Do not influenceed by manual work；Glue shell edge can strengthen edge strength and attractive in appearance from skinning；Reduce the cleaning of manual work, energy Enough it is rapidly completed assembling.

Embodiment

The utility model is described further with specific embodiment below in conjunction with the accompanying drawings.

As illustrated in fig. 1 and 2, the utility model is related to a kind of from skinning saddle, including saddle main body, saddle main body installation Sat in bicycle on bow, wherein, saddle main body includes drain pan 2 and cushion layer 1, and cushion layer 1 is with drain pan 2 by being molded one from skinning It is body formed, i.e. saddle main body does not have leather to wrap up cushion surface, and cushion layer 1 is directly used from the direct integrated through injection molding of skinning technique Shaping, simplifies technique, improves production efficiency.

Skinned foam plastics, it does surfacing without other plastics, by foaming component in foaming and molding, once Property form table material and foam core material, that is, polyurethane component is once formed to the foam plastic with solid epidermis using special process Material products.Because skinned foam carries the extexine of high intensity, so total physical and mechanical properties of its product substantially exceeds The conventional polyurethanes foaming properties of equal densities., only need to be compared with low-density from skinning system conversely, under the premise of identical physical property is required Product.So, under the premise of guaranteeing the quality, reach saving dosage, reduce the purpose of goods cost.

So should be directly to be molded by polyurethane from the cushion layer 1 of skinning saddle, and the injection molding technology is using above-mentioned From skinning technology, it is integrally formed, drain pan 2 is molded using PP materials using traditional injection moulding mode, and the drain pan 2 after shaping is placed on On the mould of saddle, and the junction of drain pan 2 and mould is sealed with sealing strip, prevent material leakage and add cushion layer 1 edge strength, it will be injected into from skinning material in mold cavity carry out injection molding afterwards, last cushion layer 1 is referred to as with drain pan 2 One, and have drain pan 2 as support, it can cause this that there is very strong intensity from skinning saddle, the weight of user can be supported Amount.Due to using above-mentioned from skinning technology, then should from the shape of skinning saddle can designed, designed according to demand, will not be by saddle The limitation of shape, this is different from the making of traditional saddle.

Saddle in the present embodiment is shaped as traditional triangle, beloid, drain pan 2 at wider position, by Screwed hole 4 is arranged with the right position of nearly rear end, and a screwed hole 5 is provided with the narrower front end position of drain pan 2.

Meanwhile should also include screw from skinning saddle, by screwed hole 4 on drain pan 2, the head of screw is located at screw Before carrying out cushion layer 1 and being molded, screw is set through screwed hole 4 close to the inboard of the side of cushion layer 1, i.e. drain pan 2 for drain pan 2 In on drain pan 2, the head of screw is directly accommodated enter in cushion layer 1 when carrying out cushion layer 1 and being molded so that cushion layer 1, drain pan 2 and screw have a style of one's own.In addition, in side of the drain pan 2 away from cushion layer 1, i.e. the exposed side outside of drain pan 2 is provided with circle Groove 3, the circular groove 3 are set with the concentric of screwed hole 4, and the circular groove 3 is used to set damping spring, and damping spring is entered Row location and installation.Meanwhile on the front end drain pan 2 from skinning saddle, screwed hole 5 also is provided with, used for screwing in screw.The rotation It is fixedly mounted as the screw of screwed hole 4 and screwed hole 5 is used to be connected with saddle beam with this and bicycle saddle tube.

In order that user's more safety and comfort when riding, it is preferred that be provided with anti-skidding rhombus in the upper surface of cushion layer 1 Decorative pattern, so it is designed to so that saddle more wear-resisting antiskid.

Should from skinning saddle use from skinning technique be molded when the step of it is as follows：

The first step：The mould of saddle is designed according to demand；

Second step：Injection forms glue shell, and sealing strip is used at the glue shell edge, can so prevent from note from skinning material Material leakage during modeling, increase edge strength；

3rd step：Kiss-coating shell, by glue shell be positioned over cushion layer injection when mould on, and to specific mold cavity within Waxed, so can surface is smooth and the easy demoulding when cushion layer is stripped, and by sealing strip in glue shell and mould Sealed between tool；

4th step：By high pressure toward inject in mold cavity molten condition from skinning material, Guan Mo；

5th step：Finished product is taken, and edge is cleared up.

After so, the exposed part of glue shell turns into drain pan 2, and the part being connected with mould from skinning material with being molded It is molded as one, turns into cushion layer 1.

The utility model has the advantages and positive effects of：Due to using above-mentioned technical proposal, using to plastics drain pan Sealing, prevents plastics drain pan material leakage, increases edge strength, toward mold cavity within injection molding technique, can so reduce Manual work, from type and wear-resisting is formed, service life can extend foam surface than common process；External form can arbitrarily make, Do not influenceed by manual work；Glue shell edge can strengthen edge strength and attractive in appearance from skinning；Reduce the cleaning of manual work, energy Enough it is rapidly completed assembling.

One embodiment of the present utility model is described in detail above, but the content is only of the present utility model Preferred embodiment, it is impossible to be considered as being used to limit practical range of the present utility model.It is all to be made according to present utility model application scope Equivalent change with improve etc., all should still belong within patent covering scope of the present utility model.
