Abstract
A kind of expanded polypropylene structure with wear-resistant fixing hole, including the structural body made of expanded polypropylene material are the utility model is related to, the structural body is provided with least one fixing hole, and the circumferential hole wall of the fixing hole is provided with one layer of plastic protective layer.Expanded polypropylene structure in the utility model by beneficial to EPP materials it is softer and moulding material it is harder the characteristics of, a moulding is embedded at its mounting hole, the intensity of EPP fixing holes can be improved.Moulding insertion EPP products inner structure effectively avoids the soft easily rupturable phenomenon of EPP materials.And simple in construction, easy to implement, operation implementation face is smaller, and guarantee is easy for installation when assembling, elasticity is moderate, it is ensured that assembling quality, is mainly used in driver's tool box and the mounting hole position of vehicle body fixation.
Description
Technical field
It the utility model is related to auto parts and components field, and in particular to a kind of expanded polypropylene with wear-resistant fixing hole
Structure.
Background technology
Expanded polypropylene（EPP）Product is commonly used for the front/rear bumper buffer stopper of automobile, pedal filling block and driver's tool
Box.Because its cost is more cheap and weight is more light, have been widely used in automobile industry.And future automobile lightweight and
In low priceization development, can more it be applied.
But individually EPP components are during long-term use, the fixed hole seat combined with vehicle body is as usage time is grown
Easily produce rupture, come off.So that the defects of EPP components can not be fixed effectively with vehicle body again, and later maintenance cost is high.
Above mentioned problem, have to be solved.
Utility model content
The technical problems to be solved in the utility model is：It is proposed a kind of expanded polypropylene knot with wear-resistant fixing hole
Structure.
The utility model is to solve the technical scheme that above-mentioned technical problem proposes to be：A kind of hair with wear-resistant fixing hole
Foaming polypropylene structure, including the structural body made of expanded polypropylene material, the structural body are provided with least one solid
Determine hole, the circumferential hole wall of the fixing hole is provided with one layer of plastic protective layer.
Further, the plastic protective layer is endoporus made of PP materials, and the PP materials endoporus is embedded at described solid
Determine in hole.
Further, the PP materials endoporus is prefabricated component, and the structural body is to be placed into shaping in the prefabricated component
Into the mould, injection molding is made again after in mould.
Further, connecting rod is provided between the PP materials endoporus, the connecting rod is together with the PP materials endoporus
It is embedded into together in the structural body.
The beneficial effects of the utility model are：
Expanded polypropylene structure in the utility model passes through beneficial to the softer spy harder and moulding material of EPP materials
Point, a moulding is embedded at its mounting hole, the intensity of EPP fixing holes can be improved.Moulding insertion EPP product inner structures have
Effect avoids the soft easily rupturable phenomenon of EPP materials.And simple in construction, easy to implement, operation implementation face is smaller, ensures assembling
When it is easy for installation, elasticity is moderate, it is ensured that assembling quality, be mainly used in the installation hole portion that driver's tool box and vehicle body are fixed
Position.
Brief description of the drawings
The expanded polypropylene structure of the present utility model with wear-resistant fixing hole is made furtherly below in conjunction with the accompanying drawings
It is bright.
Fig. 1 is the structural representation of the expanded polypropylene structure with wear-resistant fixing hole in the utility model.
Fig. 2 is the A-A of the expanded polypropylene structure with wear-resistant fixing hole in Fig. 1 to cut-away view；
Fig. 3 is the connection structure diagram between endoporus.
Embodiment
According to Fig. 1, there is the expanded polypropylene structure of wear-resistant fixing hole in the utility model, including it is poly- by foaming
Structural body 1 made of propylene material, the structural body 1 are provided with least one fixing hole.
One layer of plastic protective layer is provided with the circumferential hole wall of the fixing hole.The plastic protective layer is PP（Thermoplastic
Property resin）Endoporus 2 made of material, the PP materials endoporus 2 are embedded in the fixing hole.
It can be used as preferably：The PP materials endoporus 2 is prefabricated component, and the structural body 1 is in the prefabricated component
Into the mould, injection molding is made again after being placed into mould.
To avoid causing the displacement in hole in routine use, connecting rod, the company are provided between the PP materials endoporus 2
Extension bar is embedded into the structural body 1 of the expanded polypropylene together with the PP materials endoporus 2.
The shape of PP endoporus is not limited to the cylinder in Fig. 3, can be other any required shapes.
It is of the present utility model to be not limited to above-described embodiment, the technical scheme of above-mentioned each embodiment of the present utility model that
This can form new technical scheme with combined crosswise, and all technical schemes formed using equivalent substitution, all fall within this practicality in addition
In the protection domain of new requirement.
