Abstract

The utility model relates to a double-axis hinge of the door of the low-pressure disinfector, around the opening section of which is equipped with a sealing strip, and that is pivoted on one side of the opening section. The double-axis hinge comprises a first pivot, a second pivot and a connector. Wherein the first pivot is connected with the door of the disinfector, and the second pivot is connected with the body of the disinfector; the two pivots are connected by the connector. Therefore the disinfector door remains flatly close to the edge rather than move viably to the opening section when the air within the disinfector is in low pressure (in a vacuum state). That the disinfector door remains flatly close to the edge can have better sealing effect.

Moreover, this type of low pressure sterilization container is equipped with a circle sealing strip 940 in container 94 open outer side, after closing to make position, container door 90 starts sterilization container, promptly internal tank can be pumped into low pressure (vacuum), container door 90 is understood crush seal bars 940 and more is affixed to container 94 open side at this moment, cooperate this moment referring to shown in Figure 6, because the hinge 92 of container door 90 1 lateral margin settings has limited the relative position of 94 in this side container door 90 and container, make container door 90 can't be affixed to container 94 open side again in this side, so make container door 90 form the closure state of deflection, the degree that simultaneously also makes sealing strip 940 be extruded is inhomogeneous, at the beginning of using, can overcome the gas leakage problem by the elasticity of sealing strip 940, but sealing strip 940 can be because material ageing and the pressure of irresistible vacuum behind the life-time service, thereby make sterilization container produce gas leakage at opening part, What is more, container door 90 also might produce distortion because of long-term unbalance stress, and then cause poor sealing, have influence on the normal running of whole sterilizing installation.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of problem that existing sterilization container container door hinge design has influence on the seal of vessel effect that solves.

The technical solution of the utility model is: the container door biaxial hinge that a kind of low pressure sterilization container is provided, it is to be hubbed between sterilization container and the container door, this biaxial hinge includes one first pivot, one second pivot and a connection piece, wherein this first pivot is incorporated on the container door, this second pivot is incorporated on the container, and connector then is connected between first pivot and second pivot.

The container door biaxial hinge of aforesaid low pressure sterilization container, be connected with one first fixture in this first pivot, one side, then be connected with one second fixture in this second pivot, one side, this biaxial hinge is to combine with container door with first fixture, and combines with container with second fixture.

This utility model and prior art contrast, because hinge of the present utility model has adopted the design of twin shaft, after container door is closed to make position, and when being pumped into low pressure (vacuum) in the container, container door can more be affixed to the vessel port side by the crush seal bar, and biaxial hinge of the present utility model just can provide container door bigger freedom of movement, can be as the relative position that has limited as the existing single shaft hinge between this side container door and container, so when container door more is affixed to the vessel port side because of being pumped into low pressure (vacuum) in the container, container door still can be kept the state of smooth vessel port side, and the opening part that closes at sterilization container that can be more docile when closure, so monoenergetic does not enough provide best sealing effectiveness, simultaneously also can avoid pressure strip to damage because of vacuum pressure, or because container door life-time service and problem of causing the container door distortion to damage under state that can't be smooth.
