Abstract
The utility model relates to a cab ceiling formed through rotational molding. The cab ceiling comprises a ceiling body (1) and is characterized in that the ceiling body (1) is a hollow body which is formed through the rotational molding, and a foam material infill (3) is filled in a hollow cavity of the hollow body. The cab ceiling has good heat insulation effects and is not easy to deform.
Description
Technical field
The utility model relates to a kind of operator's compartment ceiling of rotation molding, is used for fields such as farm machinery or construction machinery and equipment.
Background technology
The operator's compartment ceiling of tradition farm machinery or construction machinery and equipment is for to be made by glass-felt plastic or cold-rolling steel, and is very heavy, and easily wears out and be corroded through the back of exposing to the weather for a long time.Operator's compartment ceiling now adopts plastic material to make more, and that plastic material is difficult for is aging, long service life, UV resistant, electrical insulating property is good, high temperature resistant and freezing and withstanding corrosion, and the weight of ceiling has also alleviated greatly simultaneously, and cost is also lower.Because of rotational molding technique is very suitable for producing the plastic product that wall is thin, face area is big, therefore methods of rotation molding that adopt are made ceiling more.
But conventional rotational moulding ceiling effect of heat insulation is bad, and in summer or winter, the driving indoor temperature that is provided with the rotational moulding ceiling can be very high or very low, and it is very uncomfortable that chaufeur is felt; In addition, the ceiling of rotation molding has a cavity naturally because of its process characteristic, and therefore the deflection of ceiling is very big when being subjected to foreign object (for example hail, stone etc.) bump, and integral body is subsided downwards, and the back is difficult to restore to the original state.
Summary of the invention
The utility model provides the operator's compartment ceiling of a kind of good heat-insulation effect, on-deformable rotation molding, and cost is low.
For achieving the above object, the technical solution adopted in the utility model is: a kind of operator's compartment ceiling of rotation molding, comprise a canopy body, it is characterized in that: described canopy body is the integrated ducted body of rotational moulding, filled with foaming material obturator in the cavity of this ducted body.
Related content in the technique scheme is explained as follows:
In the such scheme, described expanded material obturator specifically can adopt polyurethane expanded material or foaming band cross-linking polyethylene materials.
The utility model principle of work is: the coefficient of thermal conductivity of the expanded material in the cavity of ceiling canopy body has strengthened ceiling overall heat insulation effect well below the non-foamed plastic of routine; Behind the filled with foaming material, the wall thickness of the whole bearing partition of ceiling increases, and therefore counter-bending ability strengthens, and deflection is very little when being subjected to external force, easily restores to the original state after the slight deformation.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
Because the utility model just improves the thermal insulation and the counter-bending ability of ceiling by the cavity filled with foaming material inside at ceiling canopy body, promptly need not increase wall thickness, also need not adopt high-quality rotational moulding resin especially, so cost is low.
Description of drawings
Scheme drawing when accompanying drawing 1 uses on farm tractor for the utility model;
Accompanying drawing 2 is the generalized section of the ceiling in the accompanying drawing 1.
In the above accompanying drawing: 1, canopy body; 2, cavity; 3, expanded material obturator.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: shown in accompanying drawing 1～accompanying drawing 2, a kind of operator's compartment ceiling of rotation molding comprises a canopy body 1, and canopy body 1 is the integrated ducted body of rotational moulding, filled with foaming material obturator 3 in the cavity 2 of this ducted body.
Expanded material obturator 3 specifically can adopt polyurethane expanded material or foaming band cross-linking polyethylene materials.
The coefficient of thermal conductivity of the expanded material obturator 3 in the cavity 2 of ceiling canopy body 1 has strengthened ceiling overall heat insulation effect well below the non-foamed plastic of routine.During the broiling summer, can make the temperature in the operator's compartment be lower than the temperature of directly being exposed to the sun under the sun,, can make the temperature in the operator's compartment be higher than outdoor temperature in the winter of cold.
Behind the filled with foaming material, the wall thickness of the whole bearing partition of ceiling canopy body 1 increases, and therefore counter-bending ability strengthens, and the deflection of canopy body 1 is very little when being subjected to external force, or also easily restores to the original state after the slight deformation.
The thermal insulation of ceiling and the enhancing of counter-bending ability promptly are not by the increase wall thickness, neither finish by the high-quality rotational moulding resin of special employing, and cost is low.
According to requirement of client, can be made into the ceiling of different shape or various volume spaces, for example make the upper side of ceiling canopy body 1 have some guiding gutters, be beneficial to water conservancy diversion rainwater etc.
The foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the present utility model.
