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 countermeasure and radars, andReliability, stability and the high performance-price ratio of product is very important. Along with pushing away of range of applicationExtensively, coupler product is more and more worked under the environment of some inclement conditions, for example tideWet, warm southern weather, product can reduce its service life due to the impact of environment, soHow deal with the impact of adverse circumstances by the improvement of product, extending its working life becomesA technical problem urgently to be resolved hurrily. Product major part in the market all can not be used for familyOuter use, because its interiors of products does not solve the problem of waterproof. Product is long-term use moist,In the middle of warm environment, will be damaged, greatly reduce the service life of product.
Summary of the invention
Technical problem to be solved by this invention is the coupling that a kind of waterproof is provided for above drawbackClose device, there is high-effective water-proof and dust-proof effect, use safelyr, greatly improved the use longevityLife.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A coupler for waterproof, comprises the first coupler and the second coupler, wherein, described inThe first coupler outer wall is provided with external screw thread, and pitch is 0.12-0.28cm, described external screw thread cross sectionBe shaped as 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 section of described grooveBe shaped as isosceles trapezoid, described the second coupler end face is provided with sealing ring, the shape of described sealing ringThe groove of shape and the first coupler end face adapts, and 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 is taking elastic caoutchouc as material,The external diameter of its upper surface is greater than the external diameter of lower surface.
Beneficial effect of the present invention is: when use, the first coupler and the second coupler are differedClose, carry out dual-seal by sealing ring and screw thread, 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 effect nowGood, reach the more than 1.5 times of regular screw threads, greatly increase the effect of dustproof and waterproof, makeWith safer, greatly increase service life.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in the figure, a kind of coupler of waterproof, comprises the first coupler 1 and the second coupler2, described the first coupler 1 outer wall is provided with external screw thread 3, and the length L of described external screw thread 3 is5-12cm, 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, and the cross sectional shape of described groove 4 is isosceles ladderShape, described the second coupler 2 end faces are provided with sealing ring 5, and described sealing ring 5 is with elastic caoutchoucFor material, the outer diameter D of its upper surface 51 is greater than the outside diameter d of lower surface 52, described sealing ringThe groove 4 of 5 shape and the first coupler end face adapts, described the second coupler 2 outer wallsBe provided with nut 6, described nut 6 matches with described the first coupler external screw thread 3.
When use, the first coupler and the second coupler are differed and closed, by sealing ring and screw threadCarry out dual-seal, its external screw thread pitch is 0.12-0.28cm, and described thread segment is shaped asTriangle, 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 regular screw threadsMore than 1.5 times, greatly increased the effect of dustproof and waterproof, use safelyr, increaseAdd service life.
Here description of the invention and application is illustrative, not wants scope limit of the present inventionIn the above-described embodiments, therefore the present invention is not limited by the present embodiment system, and any employing equivalence is replacedExchange for technical scheme all in protection domain of the present invention.
