Abstract

The invention relates to a waterproof coupler. The waterproof coupler comprises a first coupler and a second coupler, wherein an outer screw thread is formed in the outer wall of the first coupler, a thread pitch is 0.12 to 0.28 cm, the cross-section of the outer screw thread is a triangle, the three inner corners of the triangle are alpha, beta and gamma, the alpha is equal to 60 degrees, the beta is equal to 35 degrees, the gamma is equal to 85 degrees, a groove is formed in the end face of the first coupler, the cross-section of the groove is a isosceles trapezoid, the end face of the second coupler is provided with a sealing ring, the shape of the sealing ring is adaptive to the groove in the end face of the first coupler, a nut is arranged on the outer wall of the second coupler, and the nut matches with the outer screw thread of the first coupler. The waterproof coupler has efficient waterproof and dust-proof effects, is used more safely, and greatly improves the service life.

Description

A kind of coupler of waterproof
Technical field
The present invention relates to a kind of coupler, the coupler that particularly a kind of garden illumination is used.
Background technology
Coupler is widely applied in technical fields such as microwave communication, electronic countermeasures and radars, and the reliability of product, stability and high performance-price ratio are very important.Popularization along with range of application, coupler product is more and more worked under the environment of some inclement conditions, moist, warm southern weather for example, product can reduce its useful life due to the impact of environment, so how by the improvement of product, deal with the impact of adverse circumstances, extend its working life and become a technical problem urgently to be resolved hurrily.Product major part in the market all can not be for open air use, because its interiors of products does not solve the problem of waterproof.The long-term use in the middle of moist, warm environment of product will be damaged, and greatly reduces the useful life of product.
Summary of the invention
Technical problem to be solved by this invention is that a kind of coupler of waterproof is provided for above drawback, has high-effective water-proof and dust-proof effect, uses safelyr, has greatly improved useful life.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of coupler of waterproof, comprise the first coupler and the second coupler, wherein, described the first coupler outer wall is provided with external screw thread, pitch is 0.12-0.28cm, described external screw thread cross sectional shape is triangle, a described Atria interior angle is respectively α, β, γ, α=60 °, β=35 °, γ=85 °, described the first coupler end face is provided with groove, the cross sectional shape of described groove is isosceles trapezoid, described the second coupler end face is provided with sealing ring, the groove of the shape of described sealing ring and the first coupler end face adapts, described the second coupler outer wall is provided with nut, described nut matches with described the first coupler external screw thread.
The coupler of above-mentioned a kind of waterproof, wherein, described externally threaded length is 5-12cm.
The coupler of above-mentioned a kind of waterproof, wherein, described sealing ring be take elastic caoutchouc as material, and the external diameter of its upper surface is greater than the external diameter of lower surface.
Beneficial effect of the present invention is: during use, the first coupler and the second coupler are differed and closed, by sealing ring and screw thread, carry out dual-seal, its external screw thread pitch is 0.12-0.28cm, described thread segment is shaped as triangle, a described Atria interior angle is respectively α, β, γ, α=60 °, β=35 °, γ=85 °, the experiment proved that, screw-threaded coupling best results now, has reached the more than 1.5 times of regular screw threads, has greatly increased the effect of dustproof and waterproof, use safelyr, greatly increased useful life.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in the figure, a kind of coupler of waterproof, comprise the first coupler 1 and the second coupler 2, described the first coupler 1 outer wall is provided with external screw thread 3, the length L of described external screw thread 3 is 5-12cm, pitch h is 0.12-0.28cm, described external screw thread 3 cross sectional shapes are triangle, a described Atria interior angle is respectively α, β, γ, α=60 °, β=35 °, γ=85 °, described the first coupler 1 end face is provided with groove 4, the cross sectional shape of described groove 4 is isosceles trapezoid, described the second coupler 2 end faces are provided with sealing ring 5, described sealing ring 5 be take elastic caoutchouc as material, the outer diameter D of its upper surface 51 is greater than the outside diameter d of lower surface 52, the groove 4 of the shape of described sealing ring 5 and the first coupler end face adapts, described the second coupler 2 outer walls are provided with nut 6, described nut 6 matches with described the first coupler external screw thread 3.
During use, the first coupler and the second coupler are differed and closed, by sealing ring and screw thread, carry out dual-seal, its external screw thread pitch is 0.12-0.28cm, described thread segment is shaped as triangle, and a described Atria interior angle is respectively α, β, γ, α=60 °, β=35 °, γ=85 °, the experiment proved that, screw-threaded coupling best results now, has reached the more than 1.5 times of regular screw threads, has greatly increased the effect of dustproof and waterproof, use safelyr, greatly increased useful life.
Here description of the invention and application is illustrative, not want by scope of the present invention restriction in the above-described embodiments, so the present invention do not limit by the present embodiment, and the technical scheme that any employing equivalence replacement obtains is all in protection range of the present invention.
