Abstract
The utility model discloses a sealing device, specifically a sealing rubber ring for side overflow doors, including through-hole groups. The section profile is a boss shape. The convex face of the boss shape is a sealing face. The back of the convex face is a fitting face. The boss shape is inside provided with an inner hole. The boss shape is a convex shape with a half round middle part, and the left side and right side of the boss shape are low and flat quadrangles. The boss shape is bilaterally symmetrical. The quadrangles are provided with the through-hole groups. The utility model helps to reduce the sealing area between a flashboard and the sealing rubber ring, increase the sealing compression quantity, prevent the rubber from being easily torn to open, improve the sealing performance and the service life of the sealing rubber ring, and at the same time, improve the load capacity of a hull.
Description
Technical field
The utility model relates to a kind of sealing device, specifically, refers in particular to a kind of sealing rubber ring of topside overflow gate.
Background technology
At present in the middle of shipbuilding industry; For the good seal performance in the cabin, sealing rubber ring has been installed, and the sealing rubber ring of topside overflow gate great majority employing section is the sealing rubber ring of planar shaped on door; But the sealing effectiveness of flat seal is bad, has problems such as easy tearing.
Summary of the invention
The purpose of the utility model is the above-mentioned deficiency to prior art, provides a kind of sealing performance higher, the sealing rubber ring of long service life.
For achieving the above object, realize through following technical scheme:
A kind of sealing rubber ring comprises sets of vias, and its section profile is a boss shape, and the crowning of said boss shape is a sealing surface, and the back side of crowning is installed surface, has reduced the sealing area between flashboard and the sealing rubber ring.
Be provided with endoporus in the said boss shape, be used to regulate rubber deformation.
Said endoporus is zero type hole.
Said boss shape be the middle part for convex shaped, about be low flat quadrangle, and boss shape is enantiomorphic form, and sets of vias is arranged on quadrangle, is used to install and fix bolt.
Said middle part convex shaped and quadrangle smooth connection.
Said middle part convex shaped is a semi-cylindrical hill shape.
In order to make elastic force moderate, the center of circle in said zero type hole is located on the center of circle of semi-cylindrical hill shape, and radius is the half the of semi-cylindrical hill shape radius.
Compared with prior art, the utility model sealing rubber ring has the following advantages:
1. reduce the sealing area between flashboard and the sealing rubber ring, increased seal compression, prevented that rubber from being ripped easily, improved the application life of product.
2. the endoporus through setting up is used to regulate rubber deformation, makes rubber be pressed into more easily in the flashboard door frame slot.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described.
Structure as shown in the figure is one of embodiment of the utility model sealing rubber ring, comprises sets of vias 1, and its section profile is a boss shape 2, and the crowning of said boss shape 2 is a sealing surface; The back side of crowning is installed surface, has reduced the sealing area between flashboard and the sealing rubber ring, said boss shape 2 be the middle part for semi-cylindrical hill shape 3, about be low flat quadrangle 4; And boss shape 2 is an enantiomorphic form, and sets of vias 1 is arranged on quadrangle 4, is used to install and fix bolt; Be provided with endoporus 5 in the boss shape 2, be used to regulate rubber deformation, said endoporus 5 is zero type hole; The center of circle in said zero type hole is located on the center of circle of semi-cylindrical hill shape 3, and radius is the half the of semi-cylindrical hill shape 3 radiuses, makes elastic rubber moderate; Said semi-cylindrical hill shape 3 and quadrangle 4 smooth connections, sealing rubber ring uses on the topside overflow gate, and the doorframe of said door is provided with groove; And in groove, be provided with and hold out against voussoir, crowning partly is inserted in the groove of doorframe, and the back side of crowning is installed on the door-plate; Hold out against voussoir crush seal rubber ring, guaranteed the decrement between the flashboard and rubber when door is closed, make sealing effectiveness better.
The utility model sealing rubber ring is not limited to above embodiment, so long as the scheme of mentioning in this manual and claims all can be implemented.
