Description
Technical Field
The utility model belongs to the technical field of the stopper of ventilating, concretely relates to open-type stopper of ventilating with waterproof function.
Background
The vent plug is an important part in products such as a speed changer, a controller and the like, can effectively balance the pressure inside and outside the products, and protects the internal sealing structure of the products.
The conventional vent plug structure includes an open vent plug and a pressure vent plug. The open type vent plug has poor waterproof function, complex structure and higher manufacturing cost, so the limitation is very large when the open type vent plug is actually used.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provide an open type ventilation plug with a waterproof function.
In order to achieve the above purpose, the utility model adopts the technical scheme that: an open vent plug having a water-resistant function, comprising:
the outer ring is in interference fit with the base;
the base comprises an installation column body, a limiting boss integrally formed on the outer side of the installation column body, a spiral groove formed on the outer side of the installation column body and located above the limiting boss, and a vent hole penetrating through the installation column body;
the outer ring comprises a hollow outer ring base body arranged on the base and a vent groove circumferentially arranged at the end part of the outer ring base body.
Optimally, the vent groove is opened at the end part of the outer ring base body in a cross shape.
Optimally, the outer ring is limited by the limiting lug boss.
Optimally, the inner diameter of the outer ring base body is not larger than the outer diameter of the spiral groove.
Optimally, the outer diameter of the outer ring base body is not larger than the diameter of the limiting boss.
Optimally, the depth of the outer ring base body is larger than the distance between the upper surface of the mounting column body and the limiting boss.
Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage: the utility model discloses the vent groove and base helicla flute and the air vent of outer lane are passed through to the open-type breather plug with waterproof function, make product internal cavity such as external atmosphere and derailleur be connected, outside atmospheric pressure in the effectual balanced product, and inside the peripheral helicla flute structure of base can effectually prevent that the water droplet from getting into the product moreover, has guaranteed its inside waterproof nature. The utility model discloses open-type breather plug with waterproof function is small, simple structure, application scope are wide, waterproof performance is good, the cost of manufacture is low, easy to assemble.

1. a base; 11. a vent hole; 12. a helical groove; 13. a limiting boss; 14. mounting a column body; 2. an outer ring; 21. a vent channel; 22. and an outer ring base body.
Detailed Description
The invention will be further described with reference to examples of embodiments shown in the drawings.
As shown in fig. 1 to 4, the open type vent plug with waterproof function of the present invention is generally used in a transmission and a controller to ensure the balance of the internal and external air pressures of the transmission, and mainly includes a base 1 and an outer ring 2.
As shown in fig. 3, the base 1 mainly includes a vent hole 11, a spiral groove 12, a limit boss 13, a mounting column 14, and the like. The mounting column 14 is cylindrical, and the limiting boss 13 is integrally formed on the outer side of the mounting column 14 (the limiting boss 13 is concentric, and the limiting boss 13 divides the mounting column 14 into an upper part and a lower part). The spiral groove 12 is arranged on the outer side of the mounting column body 14 and is located above the limiting boss 13 (the spiral groove 12 has a good waterproof function while ensuring the ventilation function of the vent plug). The vent hole 11 penetrates the mounting column 14.
As shown in fig. 4, the outer ring 2 mainly includes an outer ring base 22 and a vent groove 21. The hollow outer ring matrix 22 is arranged on the base 1 and limited by the limit boss 13. The vent grooves 21 are circumferentially provided at the end of the outer ring base 22 (in the present embodiment, four vent grooves 21 are provided at the end of the outer ring base 22 in a cross shape to increase the ventilation).
Further, the base 1 and the outer ring 2 are connected in an interference fit mode.
Further, the inner diameter of the outer ring base body 22 is not larger than the outer diameter of the spiral groove 12; the outer diameter of the outer ring base body 22 is not larger than the diameter of the limiting boss 13; the depth of the outer ring base body 22 is larger than the distance between the upper surface of the mounting column 14 and the limiting boss 13.
Furthermore, external air of the vent plug enters the spiral groove 12 of the base 1 through the vent groove 21 of the outer ring 2 and then passes through the vent hole 11 of the base 1, so that external air is connected with inner cavities of products such as a transmission and the like, and internal and external air pressures of the products are effectively balanced; when outside air passes through the spiral groove 12 structure of the base 1, water drops in the air can be effectively prevented from entering the product, and therefore the waterproof purpose is achieved.
In conclusion, the open type ventilation plug with the waterproof function of the utility model has the advantages of small volume, simple structure, wide application range, good waterproof performance, low manufacturing cost and convenient installation.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
