Description
Technical field
The invention belongs to container and manufacture field, particularly, the present invention relates to a kind of container cover seal locking mechanism.
Background technology
Container (comprising drier container, Chinese medicine extracting tank, reactor, mixer etc.) application is very extensive.Conventional container lid and container, be bolted vessel flange and the sealing of lid flange.Inefficiency, uncapping to close to cover wastes time and energy, and is unfavorable for automation control.
In addition, also have angle type or grooved clamp ring inclined-plane catch gear, this closing means, owing to clamp ring will being enclosed within on vessel flange and lid flange, have to open some gap at vessel flange and lid on flange, the globality that this has just destroyed flange, has weakened their intensity.And clamp ring be connecting container flange and lid flange important document, because of intensity need to also to do enough thick enough wide.Therefore angle type or grooved catch gear connect can automation control than bolt, but complex structure heaviness, and mechanical processing process complexity is not easy again to ensure the conformability on each gap inclined-plane.
Summary of the invention
The object of the invention is to, a kind of container cover seal locking mechanism is provided, this mechanism structure is simple, dependable performance, and easily processing, controls and all facilitates enforcement manually or automatically.
For achieving the above object, the present invention has adopted following technical scheme:
A kind of container cover seal locking mechanism, described mechanism comprises vessel flange 1 and lid flange 2, the internal orifice 21 of described vessel flange 1 arranges the first groove 15, on described lid flange 2, with the first groove 15 correspondence positions, the second groove 19 is set, described the first groove 15 and the second groove 19 form an epitrochoidal chamber that holds piston ring 3, the built-in piston ring 3 of described epitrochoidal chamber, described piston ring 3 is disconnected on two terminations that form a piston ring journal stirrup 4 is respectively set by piston ring gap 16, described piston ring journal stirrup 4 connects a piston ring folding driven unit, described piston ring folding driven unit is for driving the folding of piston ring gap 16, thereby control the increase of piston ring 3 diameters or dwindle.
Further, described piston ring folding driven unit comprises and turns core shift fork 6, the described two ends that turn core shift fork 6 are flexibly connected respectively a hinge-rod 5, described hinge-rod 5 is also movably connected with piston ring journal stirrup 4, the described centre that turns core shift fork 6 fixedly wears anchor shaft 14, described anchor shaft 14 one end are fixed on to be covered on flange 2, other end connecting handle 7.
Further, described piston ring folding driven unit also comprises pressing fork rack 10, and described pressing fork rack 10 is for fixedly turning core shift fork 6.
Again further, on described handle 7, locating dowel pin 9 is set, on described pressing fork rack 10, corresponding to locating dowel pin 9, knock hole 8 is set.
The core shift fork 6 that turns of the present invention is all flexibly connected by bearing pin 11 with piston ring journal stirrup 4 with hinge-rod 5, hinge-rod 5.
The medial surface of the second groove 19 of the present invention comprises groove inclined-plane 18 and spigot surface 17; When container cover is during in open mode, described groove inclined-plane 18 matches with the lower inclined plane 20 of piston ring 3, and described spigot surface 17 matches with a skew back face of piston ring 3; When container cover is during in closed state, the opposite side inclined-plane of piston ring 3 and the inclined working 12 of the first groove 15 match.
Preferably, the inclined working 12 of described the first groove 15 and sealing surface 22 bevel 5～15 degree.Because inclined working 12 and sealing surface 22 are angled.Therefore, this inclined working coordinates with the side of piston ring, piston ring 3 rise into time produce axial pressing force, perpendicular to the power of sealing surface, thereby container cover is sealed to container.
Preferably, 22 one-tenth 55～75 degree oblique angles in the groove inclined-plane 18 of described the second groove 19 and sealing surface, can stop coming off of piston ring 3.
Preferably, described the first groove 15 is for type groove, and described the second groove 19 is angle type groove.
Preferably, between the two sealing surface 22 of described vessel flange 1 and lid flange 2, elastic seal ring 13 is set.
Spigot surface 17 of the present invention play the guiding role to piston ring 3.
The core shift fork 6 that turns of the present invention is External Force Acting hinges, and External Force Acting, on handle, transmits torque to hinge-rod by turning core shift fork, then is delivered to piston ring journal stirrup, can increase or dwindle the distance of piston ring 3 gap 16, thereby forces the diameter of piston ring 3 increase or dwindle.After the diameter of piston ring 3 increases, under the combined action of spigot surface 17 and inclined working 12, piston ring 3 produces the axial pressing force perpendicular to sealing surface with inclined-plane 12, elastic seal ring 13 is out of shape, thereby makes container closure.
In the present invention, the outside diameter of piston ring 3 is less than the internal diameter of the internal orifice 21 of vessel flange 1.
The main force part of container cover seal locking mechanism of the present invention is on vessel flange 1 and lid flange 2.Therefore compressive strength is larger.And work piece---piston ring 3, be stressed and be not subject to pulling force, pressure transmission power is between vessel flange 1 and lid flange 2, that makes can be smaller, make its diameter increase suffered elastic force also little, thereby its control mechanism---it is simply small and exquisite that the hinge in piston ring folding driven unit, shift fork can do thereupon.But, because of on vessel flange angle type groove on flange of type groove and lid and the section of piston ring 3 be how much tiltedly quadrangle forms, determine positive pressure or the negative pressure of container after sealing, Main Function is on vessel flange and lid flange, and control mechanism---hinge, shift fork in piston ring folding driven unit are stressed little, add the setting of locating dowel pin and knock hole, make whole closing means reliable.
