Abstract
The utility model discloses a linkage locking mechanism with an embedded covering door, which is applicable to a container such as a steam sterilizer. The container comprises a cylindrical body and a covering door; the linkage locking mechanism comprises a covering door flange arranged on the covering door; a circular lug boss is arranged on the inner surface of the cylindrical body towards the center of the cylindrical body; the covering door flange is embedded into the cylindrical body and is sealed with the circular lug boss. Through the application of a seal ring, the cylindrical body is improved in both rigidity and roundness; meanwhile the motion range of the rubber seal ring is limited by the steel plates around the cylindrical body, so air leakage in the case of displacement of the rubber seal ring resulted from overpressure is avoided; meanwhile, the installation fit between the seal head of the covering door is greatly reduced in both diameter and depth, which is good for the miniaturization of the outer case of the pressure steam sterilizer. All the measures help reduce the weight of the whole steam sterilizer and greatly reduce production cost.
Description
Technical field
The utility model relates to a kind of cylindrical shell of the pressurized container that can uncap and the linkage locking sealing mechanism between the lid door, embedded linkage lock locking mechanism of especially a kind of lid door of vertical pressure steam sterilizer class of being used for.
Background technique
At present, in the fast linked locking mechanism that more advanced both at home and abroad vertical pressure steam sterilizer adopts, the lock sealing of lid door and cylindrical shell is general to be adopted special flange arrangement hold-down barrel upper edge and covers the O-ring seal between two flanges in student limit or cylindrical shell top is inserted in mode such as large diameter Gai Men realizes.This class designs general structure more complicated, and cost is higher, and same containers size needs the casing of large-size just can load, and its appearance design is more loaded down with trivial details.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of embedded linkage lock locking mechanism of lid door that is applied to vertical pressure steam sterilizer class, can make full use of the mechanical property of cylindrical shell and Gai Men self, reduce to cover the diameter of door, do not need to add the reinforcement flange, weight reduction, reduce production costs, simplified its appearance design requirement.
For addressing the above problem, the utility model is taked following technological scheme:
A kind of embedded linkage lock locking mechanism of lid door that is used for steam sterilizer class container, described container comprises cylindrical shell and Gai Men, described linkage lock locking mechanism comprises the lid door flange that is arranged on the lid door, it is characterized in that: the interior side direction cylindrical shell central direction of described cylindrical shell is provided with annular projection, and described loam cake flange is embedded into the inside of cylindrical shell and is tightly connected with annular projection.
Below be the utility model for further improvement of these options:
Be provided with seal ring between described loam cake flange and the annular projection.
Described linkage lock locking mechanism also comprises the locking bolt support that is arranged on the cylindrical shell outside, described locking bolt support is provided with guide sleeve, be provided with lock pin in the guide sleeve, the periphery of described container is provided with the rotating disk of annular, described rotating disk is connected with lock pin, described lid door goes up and the corresponding position of lock pin laterally has keyhole, and locking bolt can pass in and out locking or discharge cylindrical shell from keyhole.
By being connected from untie-sell, have the slip skewed slot on the described rotating disk Yu from the corresponding position of untie-sell between described rotating disk and the lock pin, described end from untie-sell is positioned at the slip skewed slot, can move along the slip skewed slot.
Beneficial effect
The utility model is by extruding a semicircle ring-type projection by pressure distortion towards the cylindrical shell central direction on cylindrical shell top on the cylindrical shell steel plate, lid door around O-ring seal under the outer flange is inserted into the inner barrel upper end, realize sealing at sealing ring place, locking bolt from outside pass the cylindrical shell upper edge keyhole pin the lid door.The characteristics of this structure are the mechanical propertys that has made full use of cylindrical shell and Gai Men self, do not need to add the reinforcement flange, and weight reduction reduces cost, and have reduced the requirement to lid door maximum diameter greatly, bring a lot of facilities for the appearance design of Sterilizers.
The utility model has saved welded flange heavy in the generic container structure by the use of seal ring, has increased cylindrical shell rigidity and circularity; Because the steel plate around the cylindrical shell defines the sphere of activities of sealing rubber ring, avoided crossing the gas leak phenomenon generation that the transposition of ambassador's O-ring seal causes simultaneously because of pressure; Also reduced between lid door and the cylindrical shell difficulty that cooperates has been installed.For the cylindrical shell of identical bore, the diameter and the degree of depth of lid door end socket are all dwindled greatly, help the miniaturization of pressure steam sterilizer outer casing simultaneously simultaneously, and these measures have alleviated complete machine weight, have reduced cost of production significantly.
Below in conjunction with drawings and Examples the utility model is further specified:
