Abstract
The utility model relates to a waterproof seal structure, including upper and lower two installation bodies and the sealing washer of setting between the two, the sealing washer is the U type, and a trapezoidal arch is respectively established in the two arms outside of U type, and open in the connecting portion outside of U type has a V type groove, the interlock portion that upward is equipped with U type groove structure on the installation body is used for placing the sealing washer, be equipped with down with interlock portion and sealing washer corresponding protruding stupefiedly on the installation body for the mutual interlock of the installation body from top to bottom. The utility model discloses a waterproof seal structure, install down the body apply for U -type sealing ring pressure cycle for the compressional deformation of U -type sealing ring to the perpendicular to screw pressure direction in last installation body U type groove, waterproof the contact region converts the space solid to by current single plane, has improved the ability of upper and lower installation body resistance to deformation greatly, has improved entire system's sealing reliability, fine improvement the waterproof seal effect.
Description
Technical field
The utility model relates to a kind of hermetic water-proof structure adopting seal ring.
Background technique
Existing sealing means adopt up and down two bodies are installed under the locking pressure of screw, two body co-extrusion seal rings, reach the effect of sealing.Adopt existing seal ring (comprising O RunddichtringO, X-shaped sealing ring, y-type seal ring), body assembly axial bolt pressure is installed and impels seal ring to produce axial deformation (note: axially refer to parallel with screw lock direction).It is after mounting simultaneously to installing body extruding up and down, and the ability of installing body assembly opposing seal ring compressive deformation is not ideal.
Model utility content
The purpose of this utility model is to provide a kind of hermetic water-proof structure, to improve the ability of installing body resistance to deformation up and down, improves the sealing reliability of whole system.
The technical solution of the utility model is: a kind of hermetic water-proof structure, comprise upper and lower two seal rings installed body and be arranged on therebetween, described seal ring is respectively establish a trapezoidal projection outside U-shaped, U-shaped two-arm, has a V-type groove outside U-shaped joint; Upper fixing body is provided with the bite of U-type groove structure for placing seal ring; Lower fixing body is provided with corresponding with bite and seal ring convex stupefied, and upper and lower fixing body is engaged mutually.
Bite on described upper fixing body is two ribs be vertically set on fixing body, to form U-type groove structure.
Described seal ring and bite interference fit.
Described seal ring two-arm is parallel and vertical with joint.
The trapezoidal projection of described seal ring is using two-arm outer side as base.Trapezoidal projection is right-angled trapezium, and right angle is positioned at the side closing on two-arm end.
Described seal ring V-type groove size is increased to notch gradually by bottom land.
Hermetic water-proof structure of the present utility model, upper and lower two install body adopts the mode of occlusion mutually to install, seal ring is arranged on the mutual engagement region of two installation bodies, the interference fit of U-shaped seal ring and upper installation body U-type groove, lower installation body is applied to U-shaped seal ring pressure and is converted to the compressional deformation perpendicular to screw pressure direction (namely radial) of U-shaped seal ring to upper installation body U-type groove, waterproof contact area converts space multistory to by existing single plane, substantially increase the ability of installing body resistance to deformation up and down, improve the sealing reliability of whole system, well improve sealed waterproof effect.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model specific embodiment.
Accompanying drawing 2 is the structural representation of seal ring in Fig. 1.
Wherein two-arm 1, joint 2, V-type groove 3, trapezoidal protruding 4, upper fixing body 5, lower fixing body 6, bite 7, convex stupefied 8.
Embodiment
As shown in Figure 1 and 2, the hermetic water-proof structure of the utility model specific embodiment, comprises upper and lower two seal rings installed body 5,6 and be arranged on therebetween.Upper fixing body 5 is provided with the bite 7 of U-type groove structure for placing seal ring; Lower fixing body 6 is provided with corresponding with bite 7 and seal ring convex stupefied 8, and upper and lower fixing body is engaged mutually.
Bite 7 on upper fixing body 5 for being vertically set on two ribs on upper fixing body, to form U-type groove structure.Seal ring and bite 7 interference fit.
Seal ring is respectively establish one trapezoidal protruding 4 outside U-shaped, U-shaped two-arm 1, has a V-type groove 3 outside U-shaped joint 2.Two-arm 1 is parallel and vertical with joint 2.Two-arm 1 and joint 2 connecting part chamfered.Trapezoidal protruding 4 using two-arm 1 outer side as base.Trapezoidal protruding 4 is right-angled trapezium, and right angle is positioned at the side closing on two-arm 1 end.V-type groove 3 size is increased to notch gradually by bottom land.
