Detailed description of the invention
Describe technical scheme of the present invention by specific embodiment below, following instance is only exemplary,Only can be used for explaining and technical scheme of the present invention being described, and can not be interpreted as technical solution of the present inventionRestriction.
The invention provides a kind of ring structure, body of a motor car panel beating rubber seal has played Jie in automobileMatter sealing, environment isolation and internal and external ornament effect. The present invention is directed to accelerator drawing in prior art and cross vehicle body metal plateThe sealing ring of gold is installed difficulty in the time assembling with vehicle body sheet metal; Sealing ring and accelerator drawing in use itBetween easily produce between relative sliding and sealing ring and vehicle body sheet metal gappedly, easily produce lacking of relative motionPoint improves.
Particularly, as shown in Fig. 4 to Fig. 9, the application's sealing ring is hollow structure, and sealing ring is integratedStructure, its profile is cylinder 101 and the frustum of a cone 102 structure that is combined into one; Described cylinder 101Bottom surface diameter be greater than the described frustum of a cone 102 maximum sole diameters. The edge of described cylinder 101 upper surfacesPlace is provided with downward chamfering 108.
Described sealing ring is axially provided with tubular conduit 105; One end of described tubular conduit 105 protrudes from instituteThe upper surface of stating cylinder 101 forms protuberance 103, and the other end of described tubular conduit 105 is opened on instituteState the frustum of a cone 102 lower surfaces; This structure can be to the further axial restraint of accelerator drawing 114. Described pipeThe junction of the upper surface of the outer surface of shape path 10 5 and described cylinder 101 is provided with chamfering 107.
