Embodiment
Be described in detail the technical solution of the utility model below by specific embodiment in order further to explain.
A kind of rubber sealing ring of the present utility model, as Figure 1-3, comprises ringwise seal ring main body 1.
The outside of seal ring main body 1 is formed with the ring-shaped step that two front and back are arranged in parallel, and the cross section of this ring-shaped step is reversed acanthoid, and front end extends back, and this ring-shaped step comprises the first step 2 in front, and second step 3 in rear; The inside of first step 2 is formed with the first toroidal cavity 21; The inside of second step 3 is formed with the second toroidal cavity 31; The inner side of seal ring main body 1 is laid with multiple annular flange flange that are arranged in parallel vertically 4.The utility model is mainly used in plug 5 to insertion pipe and the surface of contact of socket 6 seals, break through the structural form of traditional rubber seal, first step 2, second step 3 front and back arrange, and cross section is most advanced and sophisticated reversed acanthoid backwards, in use, the utility model is set in the corresponding seal groove of plug 5 outer circumferential face near the mode of plug 5 ends with first step 2, the tip of first step 2 and second step 3 protrudes from the notch of seal groove, in the time that plug 5 inserts socket 6, the madial wall of socket 6 is taken advantage of a situation and is overwhelmed first step 2 and second step 3, plug 5 is taken advantage of a situation and is inserted in socket 6, in the time that plug 5 is wanted to extract socket 6, the madial wall of socket 6 carries out contrary gesture effect to first step 2 and second step 3, increase the pretightening force of whole seal ring to plug 5 and socket 6, strengthen sealing effect, increased frictional force simultaneously, effectively prevent that plug 5 from unwillingly deviating from from socket 6, and first toroidal cavity 21 and the second toroidal cavity 31 increased respectively the amount of deformation of first step 2 and second step 3, improve the elastic performance of first step 2 and second step 3, strengthen the laminating tightness of first step 2 and second step 3 and socket 6 madial walls, and then strengthened the sealing of seal ring and socket 6, annular flange flange 4 has increased the amount of deformation of seal ring main body 1 inner side surface simultaneously, has improved the elastic performance of seal ring main body 1, has strengthened the laminating tightness of seal ring main body 1 inner side surface and plug 5 seal groove bottom lands, and then has strengthened the sealing of seal ring and plug 5.The cross section of the second toroidal cavity 31 specifically can be circle.
Preferably, between second step 3 and seal ring main body 1, be formed with the annular groove 32 being arranged with by axle head, be to be alternate form between second step 3 and seal ring main body 1, annular groove 32 offers the space of second step 3 resiliently deformables, the inner side of second step 3 is formed with an annular leg 33 of being located at annular groove 32 madial walls simultaneously, annular leg 33 carries out elastic support to second step 3, and above structure can further strengthen the elastic performance of second step 3.
