Abstract
Provided is a waterproof and dustproof ventilating bolt which comprises a bolt body and a waterproof ventilator. A ventilating groove passing through the bottom of the hollow cylinder is formed in the hollow cylinder of the bolt body. A fixing portion is disposed on the outer surface of the hollow cylinder. A ventilating channel is formed in a cap cover on the hollow cylinder. At least one end of the ventilating channel is equipped with an opening exposed out of the outer surface of the cap cover. The waterproof ventilator is disposed between the ventilating groove and the ventilating channel and is produced by metallic material in a powder metallurgy manner. A plurality of micro gaps larger than air molecules but less than water molecules are formed in the waterproof ventilator. When the hollow cylinder of the bolt body passes through a hole on the housing a default device, the plurality of micro gaps of the waterproof ventilator block water molecules and dust particles. But air inside and outside the housing is still circulated so as to achieve waterproof, dustproof, and ventilating effects.
Description
Technical field
The utility model provides a kind of water proof and dust proof ventilation plug, especially refers to be installed on default apparatus, to prevent water, divides dust to enter default apparatus inside, and can be for the key of default apparatus inner air and outer air circulation.
Background technology
Along with scientific and technological progress, as board, equipment, electronic product, power equipment or signboard etc., many devices all can be arranged on open air or touch in the environment of water in meeting, no matter but be electronic installation or mechanical device, if moisture content enters into device inside, and contact its inner member, just may produce short circuit, the situation of damage or corrosion, and also can touch dust while installing out of doors, if dust enters into device inside, dust contacts its inner member and also can produce short circuit, the situation of damage or corrosion, so, generally be installed in this kind of device in the ring mirror and all can do the design of waterproof, to be provided with waterproof adhesive tape at each joint of shell, the waterproof constructions such as dewatering ditch, allow outside moisture content or the dust can't be via access to plant inside, gap.
Although this mode can be avoided outside moisture content or dust access to plant inside, but its inner member of many devices is arranged when running, can produce high heat allows temperature rise, because each joint of shell has all been intercepted by waterproof construction, so inner air and outer air can't circulate, but under the situation that the internal heat air can't be discharged, its inner air just can allow because temperature improves volumetric expansion, because external and internal pressure difference, making shell be subject to hot-air pushes, allow each joint of shell just can produce gap, institute is in order to may have moisture content or dust to enter into device inside via gap, moreover, after the long-time running of device, shell also can be pushed generation deformation because of being subject to for a long time hot-air, and allow each joint of shell form firm gap, cause waterproof and dust reduction capability to be lost, just can allow device produce damages.
Therefore, how to solve known problem and disappearance, allow the device not only can waterproof and dustproof, and inner air and outer air be negotiable again, is the direction place that the relevant manufacturer that is engaged in the industry desires most ardently the research improvement.The utility model applicant, because above-mentioned problem and disappearance collected related data, via in many ways assessing and considering, and, to engage in the many years of experience of the industry accumulation, via constantly studying and revising, begins to design the patent birth of this kind of water proof and dust proof ventilation plug.
