Embodiment
Fig. 1~2 are please referred to, the present embodiment provides a kind of sealing devices 200 for radar installation.Sealing device 200 wraps
It includes：Installation frame ontology 210, seal washer 220 and the cover board 230 detachably connected for same installation frame ontology 210.
The side of cover board 230 is convexly equipped with first annular flange 231 and the second annular flange 232,231 ring of first annular flange
Set on the outside of the second annular flange 232.
Second annular flange 232 includes the first raised section 232a and the second raised section 232b, the first raised section 232a connections
Between cover board 230 and the second raised section 232b.The cross section of first raised section 232a is rectangular, the cross of the second raised section 232b
Section is rounded.Along the radial direction of the second annular flange 232, the first raised section 232a thickness is less than the thickness of the second raised section 232b
Degree.
It includes for the first vallecular cavity 221 with the first raised section 232a cooperations that seal washer 220, which has mating groove, mating groove,
With for the second raised section 232b cooperation the second vallecular cavity 222, the second vallecular cavity 222 by the first vallecular cavity 221 bottom notch shape
At.
The oral area of installation frame ontology 210 has first annular slot 211 for housing first annular flange 231 and is used for
The bottom of second annular groove 212 of accommodating seal washer 220, first annular slot 211 has elastic cord breaker 211a.
Sealing device 200 can realize being obviously improved for sealing effect using its Multi-level sealing structure.When the second convex annular
When edge 232 is matched with mating groove, the first raised section 232a is matched with the first vallecular cavity 221, and the second raised section 232b is matched with second
Vallecular cavity 222.The special construction of second annular flange 232 and mating groove can avoid the second annular flange 232 from seal washer 220
Middle abjection ensures the compactness and stability that coordinate between the second annular flange 232 and seal washer 220.
When cover board 230 is mounted to installation frame ontology 210, seal washer 220 is pressed on the second annular groove by cover board 230
212.In this state, the second raised section 232b can apply extruding force to seal washer 220, after seal washer 220 is squeezed
Elastic deformation can occur, after elastic deformation occurs for seal washer 220, the close installation frame ontology 210 of seal washer 220
Side occur to squeeze compression, the remainder of seal washer 220 can converge towards the oral area of the second annular groove 212, but due to covering
Plate 230 again can be by entire seal washer 220 towards pressing in the second annular groove 212, and therefore, final effect is shown as：It is close
The side of the close installation frame ontology 210 of seal washer 220, which occurs to squeeze, to be compressed, and the close cover board 230 of seal washer 220
It is then converged towards the second raised section 232b side.Due to the circular in cross-section of the second raised section 232b, this allows for the second protrusion
Section 232b can be preferably bonded with seal washer 220, and the combination for greatly improving the second raised section 232b and seal washer 220 is tight
Close property, to keep the elastic acting force between the second raised section 232b of ground and seal washer 220 stronger and more uniform, anti-mistake
Come, the second raised section 232b can apply seal washer 220 more uniform, intensity bigger elastic acting force, make sealing
Washer 220 is closer, is more fully bonded with the cell wall of the second annular groove 212 and slot bottom, substantially improves seal washer 220 and peace
The compactness combined between dress frame body 210 improves the sealing effect between seal washer 220 and installation frame ontology 210
Fruit.
Further, when first annular flange 231 is matched with first annular slot 211, first annular flange 231 with positioned at the
The elastic cord breaker 211a of one annular groove, 211 bottom offsets, after first annular flange 231 and elastic cord breaker 211a fits
Second level sealing can be formed, sealing effect is further increased.
In addition, its disassembly and installation is all very simple, substantially reduces operation and use difficulty.
In general, for radar installation sealing device 200 using its unique secondary seal structure make its waterproof,
Salt spray proof superior performance can effectively prevent that salt fog leakage occurs, to substantially increase sealing effect and isolation performance, help
In being formed with effect protection to internal component, prevents corrosion of equipment impaired, substantially prolong service life.
Further, the second annular flange 232 is interference fitted with seal washer 220.By the design, can further increase
Strong second annular flange 232 is with the elastic acting force between seal washer 220, to further increase seal washer 220 and peace
The elastic acting force between frame body 210 is filled, sealability is further increased.
Further, along the radial direction of the second annular flange 232, the second raised section 232b thickness is the first raised section 232a thick
2~3 times of degree.In the present embodiment, along the radial direction of the second annular flange 232, the second raised section 232b thickness is the first protrusion
3 times of section 232a thickness.
Further, along the axial direction of seal washer 220, the height of projection of first annular flange 231 is equal to seal washer 220
Thickness, the height of projection of first annular flange 231 is 1.5~2 times of the height of projection of the second annular flange 232, gasket
The thickness of circle 220 is 1.1~1.2 times of the depth of the second annular groove 212.In the present embodiment, along the axis of seal washer 220
To the height of projection of first annular flange 231 is 2 times of the height of projection of the second annular flange 232, the thickness of seal washer 220
Degree is 1.2 times of the depth of the second annular groove 212.
By designing above, it can further improve the integral sealing ability of sealing device 200.
Further, one end of the separate cover board 230 of first annular flange 231 has for same elastic cord breaker 211a phases
The cross section semicircular in shape of the protrusion 231a supported, protrusion 231a.
By designing above, when first annular flange 231 offsets with elastic cord breaker 211a, protrusion 231a is to elasticity
Buffer layer 211a is squeezed to make elastic cord breaker 211a that elastic deformation occur, since the cross section of protrusion 231a is in half
Circle, the contact area between protrusion 231a and elastic cord breaker 211a greatly increases, so that sealing effect obtains
A degree of reinforcement.
Further, in the present embodiment, detachably connected by screw rod between cover board 230 and installation frame ontology 210.
In conclusion 200 waterproof of sealing device, salt spray proof superior performance for radar installation, can effectively prevent sending out
Raw salt fog leakage helps to be formed with effect protection to internal component, prevent to substantially increase sealing effect and isolation performance
Corrosion of equipment is impaired, substantially prolongs service life.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
