Abstract
The utility model discloses a waterproof breathable breather plug. The breather plug comprises a bolted cap, a waterproof breathable film, a bolt, a rubber ring and a nut, wherein the hollow bolt top is stuck with the waterproof breathable film; the nut and the bolt are in threaded connection and sealed by the rubber plug; and the bolted cap is clamped at the upper part of the bolt. The bolted cap and the bolt are clamped in the following way: the edge of the bolted cap is fixed with a plurality of downward bolted cap projecting columns; the top of the bolt is upwards fixed with a bolt heave matched with the bolted cap projecting columns; the inside of the bolt heave is provided with a groove; and the bolted cap projecting columns are clamped in the groove of the bolt heave, thus forming a breathable hole between the bolted cap and the bolt. Normally, the nut is a hexagonal nut for convenience of installation of using tools. The waterproof breathable breather plug made by the technical scheme has the following advantages: (1) simple structure and convenient installation; (2) excellent waterproof and breathable performances, and easy cleaning and replacement; and (3) low price cost.
Description
Technical field
The utility model belongs to the bolt cock body structure field of waterproof and breathable, be specifically at outdoor lamp particularly the water-proof breathable properties of car light require and a kind of water-proof ventilated respiration plug of designing.
Background technology
Present existing water proofing property breather plug normally adopts totally-enclosed design, particularly for the breather plug of using on light fixture that uses out of doors or the electronic product, adopt totally enclosed design can play waterproof action fully, but because the light fixture or the electronic product of outdoor use often need frequently carry out switching manipulation in running, this can cause the closed interior space of light fixture or electronic product to form the rapid increase of inner and outer air pressure difference owing to the temperature acute variation, under huge gas pressure, some connecting portions of sealing shell can produce the close phenomenon of bad sealing, thereby the rainwater that causes external environment, moist fog infiltrates the inside of device from leak, steam accumulates in light fixture for a long time or electronic device inside can cause circuit performance aging, reduce serviceability, cause that fault takes place, and finally shortens its service life.
Summary of the invention
The purpose of this utility model is can only waterproof can not breathe freely and cause the inner and outer air pressure difference excessive in order to solve above-mentioned existing water proofing property breather plug, damages hermetically-sealed construction, finally causes poorly sealedly, produces the defective of leaking.
Realize that the above-mentioned purpose the technical solution of the utility model is that a kind of water-proof ventilated respiration plug comprises the bolt cap, waterproof ventilated membrane, bolt, cushion rubber, nut, waterproof ventilated membrane is pasted at the bolt top of hollow, nuts and bolt is threaded, and uses rubber sealing, and the bolt cap is connected to bolt top.The clamping in the following way of bolted cover and bolt: bolted cover hat brim edge is fixed with several downward bolt block projections, the bolt top upwards is fixed with the stud protrusion that is complementary with bolt block projection, and this stud protrusion inboard has groove, bolt block projection is connected in the groove of stud protrusion, thereby forms air-vent between bolt block and bolt.Nut is installed for making things convenient for tool using, is generally six-sided nut.
The water-proof ventilated respiration plug that utilizes the technical solution of the utility model to make has the following advantages: (1) is simple in structure, and is easy for installation; (2) waterproof and permeability are outstanding, clean and change easily; (3) Costco Wholesale is cheap.
Description of drawings
Fig. 1 is the structural representation of water-proof ventilated respiration plug described in the utility model;
Fig. 2 is the sectional structure chart of the described water-proof ventilated respiration plug of this Fig. 1;
Among the figure, 1, the bolt cap; 2, waterproof ventilated membrane; 3, bolt block projection; 4, air-vent; 5, stud protrusion; 6, bolt; 7, cushion rubber; 8, nut.
The specific embodiment
Specifically describing of the present utility model below in conjunction with accompanying drawing, is the structural representation of water-proof ventilated respiration plug described in the utility model as Fig. 1, and Fig. 2 is the anatomical structure figure of this water-proof ventilated respiration plug, as shown in the figure, this breather plug is by bolt cap 1, waterproof ventilated membrane 2, bolt 6, cushion rubber 7, nut 8 is formed, and bolt is a hollow, waterproof ventilated membrane is pasted at the top, nuts and bolt is threaded, and uses rubber sealing, has prevented that permeable phenomenon from taking place.The bolt cap is connected to bolt top, provided a kind of mode of clamping in the present embodiment, promptly, bolted cover hat brim edge is fixed with several downward bolt block projections 3, the bolt top upwards is fixed with the stud protrusion 5 that is complementary with bolt block projection, and this stud protrusion inboard has groove, and bolt block projection is connected in the groove of stud protrusion, thereby forms air-vent 4 between bolt block and bolt.During this water-proof ventilated respiration plug work, air exchanges through waterproof ventilated membrane and outside by the bolt of hollow, and waterproof ventilated membrane water and extraneous isolation does not take place the leakage of water.
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; those skilled in the art to some part wherein some changes that may make all embodied principle of the present utility model, belong within the protection domain of the present utility model.
