Description
Technical Field
The invention belongs to the technical field of connecting discs, and particularly relates to a high-sealing connecting disc.
Background
Automotive suspensions are devices that elastically couple the frame to the axle of an automobile. It is generally composed of elastic element, guide mechanism and shock absorber, and is mainly aimed at relaxing the impact transferred from uneven road surface to vehicle frame so as to raise the comfortability of riding.
The shock absorber is used for inhibiting the shock when the spring absorbs the shock and rebounds and the impact from the road surface. The damping device is widely applied to automobiles and is used for accelerating the attenuation of the vibration of a frame and an automobile body so as to improve the driving smoothness of the automobiles. When the shock absorber passes through the uneven road surface, although the shock absorbing spring can filter the shock of the road surface, the spring can still reciprocate, and the shock absorber is used for inhibiting the spring from jumping.
The connecting disc is an important part in the shock absorber, however, the connecting and sealing structure between the cover body and the shell in the existing connecting disc is not ideal enough, so that the existing connecting disc is weak in air pressure bearing capacity and poor in sealing performance.
Disclosure of Invention
The invention aims to provide a high-sealing-performance connecting disc which has the characteristics of high sealing performance and good reliability.
The purpose of the invention is realized as follows: the utility model provides a high leakproofness connection pad, includes lid and casing, its characterized in that: the center of lid is equipped with the axle journal of indent structure, is equipped with the enstrophe edge of cover in the axle journal outside on the casing, the rubber ring between enstrophe edge and the lid, the up end and the lid lower surface sealing connection of rubber ring, the lower terminal surface and the last surface sealing connection on enstrophe edge of rubber ring, the internal perisporium and the axle journal outer wall sealing connection of rubber ring.
The invention is further configured to: and an outer convex edge of a downward-turning structure is also arranged on the peripheral edge of the cover body.
The invention is further configured to: and an annular groove with an inwards concave arc structure is arranged on the peripheral wall of the rubber ring.
The invention is further configured to: the shaft neck is internally provided with a shaft hole and an internal thread arranged above the shaft hole.
Through adopting above-mentioned technical scheme for can realize sealing connection between the internal perisporium of rubber ring and the axle journal, improve the connection leakproofness between it, thereby improve the connection reliability between lid, rubber ring and the casing three.
Drawings
FIG. 1 is a schematic structural view of the present invention;
the reference numbers in the figures are: 1. a cover body; 2. a housing; 3. a journal; 4. inward turning edges; 5. a rubber ring; 6. an outer convex edge; 7. a ring groove; 8. a shaft hole; 9. an internal thread; 10. an arc-shaped section; 11. a first tapered section; 12. a second tapered section.
Detailed Description
The invention will be further described in the following with reference to specific embodiments in conjunction with the accompanying drawings, see fig. 1:
the utility model provides a high leakproofness connection pad, includes lid 1 and casing 2, its characterized in that: the center of lid 1 is equipped with the axle journal 3 of indent structure, is equipped with the enstrophe edge 4 of cover in the axle journal 3 outside on the casing 2, and enstrophe edge 4 and the lid 1 between rubber ring 5, the up end of rubber ring 5 and lid 1 lower surface sealing connection, the lower terminal surface and the enstrophe of rubber ring 5 are along the upper surface sealing connection of 4, the internal perisporium and the 3 outer wall sealing connection of axle journal of rubber ring 5.
The rubber ring 5 and the cover body 1, the inward turning edge 4 and the shaft neck 3 can be connected in a hot melting mode to realize sealing, the sealing connection between the inner circumferential wall of the rubber ring 5 and the shaft neck 3 can be realized, the connection sealing performance between the rubber ring and the shaft neck is improved, and the connection reliability between the cover body 1, the rubber ring 5 and the casing 2 is improved.
The outer periphery of the cover body 1 is also provided with an outer convex edge 6 of a downward-turning structure, and the outer convex edge 6 is also connected with the rubber ring 5, so that the connection reliability of the rubber ring 5 can be improved.
Be equipped with annular 7 of indent arc structure on the periphery wall of rubber ring 5, the setting of annular 7 can improve the shock attenuation shock-absorbing capacity of rubber ring 5.
Be equipped with shaft hole 8 in the axle journal 3 and arrange the internal thread 9 of shaft hole top in, the setting up of shaft hole 8 and internal thread 9 makes things convenient for lid 1 directly to be connected fixedly with external part, and the structure is simplified.
The inner edge turning 4 comprises an arc transition section 10, a first conical section 11 and a second conical section 12 which are sequentially connected, the arc transition 10 is connected with the shell 2, the first conical section 11 is of a forward frustum structure, the second conical section 12 is of an inverted frustum structure, and the axial pressure-bearing capacity between the shell 2 and the cover body 1 can be increased through the structural design of the arc transition section 10 and the first conical section 11; through the structural design of the second taper section 12, the bottom surface of the rubber ring 5 is also attached to the second taper section 12, so that the connection strength and the sealing property between the rubber ring 5 and the inverted edge 4 can be increased.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
