The utility model is further set to: described articulated elements is hinge.
By adopting technique scheme, gemel connection is between the first link and the second link, bolt wore the assembling that completes O-ring seals after the tapped hole on fixed hole on hinge and the first link, the second link successively, the first link and the second link are hinged, between the first link and the second link, not only removably connect, but also can be rotatably connected, reduced the volume of O-ring seals, can save the cost of transportation of O-ring seals.
The utility model is further set to: on described the first link inwall and the second link inwall, be equipped with arc groove, described arc groove is provided with and the equal suitable spring of arc groove shape, size.
By adopting technique scheme, on the first link inwall and on the second link inwall, all offer the arc groove for spring fixed placement, by spring fitting in arc groove, spring is fitted on arc groove inwall, strengthened the elasticity of O-ring seals, thereby strengthen its sealing effect, greatly improve sealability.
The utility model is further set to: described spring one side and the welding of arc groove inwall.
By adopting technique scheme, the corresponding arc groove of spring one side is welded on arc groove inwall, prevent that spring from departing from arc groove, strengthened the connectivity robustness between spring and arc groove, because spring has elasticity, be wrapped in the first link on spring and the elasticity of the second link and all strengthen, when the elasticity of O-ring seals is strengthened, its structural strength is also enhanced.
The utility model is further set to: between described the first link upper-end surface inwall and the first link lower end surface inwall, be installed with spring, between described the second link upper-end surface inwall and the second link lower end surface inwall, be also installed with spring, described spring is all axially disposed within the first link and the second link.
By adopting technique scheme, utilize the flexible of spring, even if being out of shape also by compression, O-ring seals can recover elasticity at once, when O-ring seals be placed in two by Sealing between time, after being axially disposed within respectively spring in the first link and the second link and being squeezed there is deformation in compression, after removing by Sealing, spring recovers elastic potential energy and elastic potential energy is converted to kinetic energy, thereby move back and forth, and spring has elasticity, strengthen the elasticity of O-ring seals, thereby strengthened its sealing effect, greatly improved sealability.
The utility model is further set to: the making material of described the first link and the second link is nitinol.
By adopting technique scheme, nitinol is a kind of marmem, marmem is the plastic deformation of self automatically to be reverted under a certain specified temp to the special alloy of original-shape, and nitinol also has the advantages such as wear-resistant, anticorrosive and superelasticity, the first link and the second link that adopt nitinol to make also have the performances such as wear-resistant, anticorrosive and superelasticity, have greatly strengthened the sealing effect of O-ring seals.
The utility model is further set to: the outer surface of described the first link and the second link is all coated with Si Taili cemented carbide.
By adopting technique scheme; Si Taili cemented carbide has good wear resistance and corrosion resistance; outer surface at the first link and the second link all sprays or electroplates officials Tai Li cemented carbide; when O-ring seals carries out seal action; Si Taili hard alloy layer can well protect body not to be subject to the corrosion of extraneous fluid or oxygen, has extended the working life of O-ring seals.
The utlity model has following advantage: can be for convenience detach, when this O-ring seals damages, as long as change the part of damaging, saving resource, the utilization ratio of raising O-ring seals.
