Description
Technical Field
The utility model relates to a transport case, concretely relates to rotational moulding case.
Background
At present, in the transportation, generally need use transportation such as rotational moulding case to use the box, current rotational moulding case on the market adopts ordinary box structure more, and single structure when needs transport high altitude areas such as plateau, because the case is sealed airtight, inside and outside exist the pressure differential and can not open the case. In order to solve the problems, a novel rotational molding box is particularly necessary.
Disclosure of Invention
The utility model aims at providing a rotational moulding case, structural design is reasonable, can effectively balance the inside and outside atmospheric pressure of case, makes things convenient for the case to use in high altitude area, and the practicality is strong, easily uses widely.
In order to achieve the above purpose, the present invention is realized by the following technical solution: the utility model provides a rotational moulding case, includes lid, box, handle, buckle closure and breather valve, and the lid passes through the buckle closure lock joint on the box, installs the handle on the box, and the breather valve is still installed to the box, the breather valve is including ventilative valve cap, ventilative valve gap, waterproof ventilated membrane, bolt, O type sealing washer and nut, and the nut is located inside the box, and the breather valve is whole to be fixed on the box through bolt and nut, is provided with O type sealing washer on the bolt, and the bolt outside is provided with waterproof ventilated membrane, and ventilative valve gap and ventilative valve cap are installed in the waterproof ventilated membrane outside.
Preferably, the waterproof breathable film is made of polytetrafluoroethylene, and is waterproof, breathable and corrosion-resistant.
Preferably, the bottom of the box body is provided with a quick-disassembly universal wheel, so that the use convenience of the box is improved.
The utility model has the advantages that: the device can effectively balance the atmospheric pressure inside and outside the box, so that the box can be conveniently opened and used in a high-altitude area, the reliability is higher, and the application prospect is wide.
Drawings
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments;
fig. 1 is a schematic perspective view of the present invention;
fig. 2 is a schematic plan view of the present invention;
fig. 3 is an exploded schematic view of the vent valve of the present invention.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
Referring to fig. 1 to 3, the following technical solutions are adopted in the present embodiment: the utility model provides a rotational moulding case, includes lid 1, box 2, handle 3, buckle closure 4 and breather valve 5, and lid 1 passes through buckle closure 4 lock joint on box 2, installs handle 3 on the box 2, and breather valve 5 is still installed to box 2, breather valve 5 is including ventilative valve cap 501, breather valve cap 502, waterproof ventilated membrane 503, bolt 504, O type sealing washer 505 and nut 506, and nut 506 is located inside the box 2, and the breather valve is whole to be fixed on box 2 through bolt 504 and nut 506, is provided with O type sealing washer 505 on the bolt 504, and the bolt 504 outside is provided with waterproof ventilated membrane 503, and ventilative valve cap 502 and ventilative valve cap 501 are installed to waterproof ventilated membrane 503 outside.
It is worth noting that the waterproof breathable film 503 is made of polytetrafluoroethylene, and is waterproof, breathable and corrosion resistant.
This embodiment can install the universal wheel of dismantling fast in 2 bottoms of box for the rotational moulding case can be pulled away like the suitcase, also can push away, also can hand and walk when not using, improves the convenience of use of case greatly.
The specific implementation mode can also enable the rotational molding box to be changed into a code box by installing the electromagnetic controller and the code controller, and expand the application scene of the rotational molding box.
This embodiment installs the breather valve additional on the basis of traditional rotational moulding case structure, through the inside and outside atmospheric pressure of breather valve balance box, waterproof ventilated membrane in the breather valve adopts the waterproof ventilated membrane of polytetrafluoroethylene, waterproof performance is good, high stability, corrosion resistance, weather resistance is good, can effectively prevent the moisture entering through waterproof ventilated membrane, simultaneously can get into the air, thereby solve the rotational moulding case and can not open the problem of case because of inside and outside pressure differential in plateau district, more make things convenient for the case to use in high altitude area, this box also is applicable to the sea transportation simultaneously, high low temperature environment, use in rain and fog weather and the humid environment, therefore, the high applicability is wide, and wide market application prospect is possessed.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
