Description
Technical field
The utility model relates to a kind of two-door sterilizer hermatic door safe locking device, belongs to the supporting facility of sterilizer.
Background technology
In some medical institutions,, there are bacterium chamber and bacteria free room to isolate fully in order to prevent to pollute.There is the transmission of article between bacterium chamber and the bacteria free room to realize by two-door sterilizer, in order to have prevented that the bacterium district from polluting aseptic area, this just requires two-door sterilizer to have bacterium door and aseptic door not to open simultaneously, how can accomplish two doors are accurately operated, and be the problem that people are concerned about.
The utility model content
The purpose of this utility model is to provide a kind of two-door sterilizer hermatic door safe locking device, and is simple in structure, and precise control, convenience can guarantee that have the bacterium door and the aseptic door of two-door sterilizer can not be opened simultaneously, and be safe and reliable.
Two-door sterilizer hermatic door safe locking device described in the utility model, the door lock screw that is installed on the sterilizer main body is arranged, the door lock screw mandrel supporting with the door lock screw is installed on the hermatic door, it is characterized in that establishing many ribs axle at the locking end of door lock screw mandrel, correspondingly with many ribs axle on the door lock screw, be provided with perforate, corresponding perforate is provided with electromagnetic lock, and the lock pin of perforate and electromagnetic lock adapts.
The utility model has been set up many ribs axle and electromagnetic lock, realize normal locking by door lock screw and door lock screw mandrel, further control lock-out state by electromagnetic lock again, especially can realize two-door sterilizer bacterium door and two hermatic doors of aseptic door are arranged the time locking or the locked condition of interlocking, have the bacterium door and the aseptic door that can guarantee two-door sterilizer well can not be opened simultaneously, and be safe and reliable.
In the utility model:
The fin Cross-section Design of many ribs axle can be become ratchet shape, in the time of can realizing rotating the door lock screw mandrel, can continue rotational lock at closing time, and reverse stop be more safe and reliable.In like manner, in order to strengthen locking property, many ribs axle can be designed to do not wait gauge structure, the inner end external diameter is big, and the outer end external diameter is little.
The lock pin of electromagnetic lock can be placed fairlead, guarantee accurately moving of lock pin.
Fairlead can be fixedlyed connected with electromagnetic lock by connecting support, can be fixed to together on the sterilizer main body.
At the tapping jointing, joint is threaded with fairlead on the door lock screw, flexible, dependable performance also can be designed to simply be threaded between door lock screw and joint.
From this, the utility model compared with prior art has following beneficial effect:
Simple in structure, by further accurately control of electromagnetic lock, not only can guarantee that have the bacterium door and the aseptic door of two-door sterilizer can not be opened simultaneously, and convenient operation and control, safe and reliable.
Description of drawings
Fig. 1, the utility model one example structure schematic diagram.
Door lock screw mandrel among Fig. 2, Fig. 1 and door lock screw structural relation schematic diagram.
Among the figure: 1, electromagnetic lock 2, connection support 3, packing ring 4, hold-down nut 5, lock pin 6, perforate 7, many ribs axle 8, door lock screw 9, joint 10, fairlead 11, door lock screw mandrel.
The specific embodiment
The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.
As shown in the figure, two-door sterilizer hermatic door safe locking device described in the utility model, the door lock screw 8 that is installed on the sterilizer main body is arranged, the door lock screw mandrel 11 supporting with door lock screw 8 is installed on the hermatic door, the locking end of door lock screw mandrel 11 is provided with many ribs axle 7, correspondingly with many ribs axle 7 on door lock screw 8, be provided with perforate 6, on the door lock screw 8 at perforate 6 place's jointings 9, door lock screw 8 is threaded with joint 9, joint 9 also is threaded with fairlead 10, perforate 6 adapts with the lock pin 5 of electromagnetic lock 1, lock pin 5 places fairlead 10, fairlead 10 is fixedlyed connected with electromagnetic lock 1 by connecting support 2, is fixed by screw and hold-down nut 4 and packing ring 3 etc.
Wherein: the fin cross section of many ribs axle 7 is ratchet shape, is designed to unimpeded at closing time (arrow in the diagram is the turn direction of closing the door), stop when opening the door.Many ribs axle 7 is not for waiting gauge structure, and inner end (with door lock screw mandrel link) external diameter is big, and the outer end external diameter is little, the convenient locking situation of regulating.
Operating principle:
The open and close of two hermatic doors of two-door sterilizer realize by separately door lock screw mandrel and door lock screw respectively.Electromagnetic lock 1 is getting under the electricity condition, and its lock pin 5 can be withdrawn; Under power failure state, its lock pin 5 stretches out under the elastic force of portion's spring within it.Control the electric and outage of getting of electromagnetic lock 1 by control signal, thereby control the lock-out state of electromagnetic lock automatically, exactly.
During device powers down, under the control of electromagnetic lock, two hermatic doors of two-door sterilizer are not all opened; When equipment gets electric operation, under the control of electromagnetic lock, can only guarantee that two-door sterilizer has a hermatic door to open.
The course of work: when beginning to sterilize, operating personnel are when having bacterium chamber one side to open hermatic door to put into sterilizing article, the hermatic door of bacteria free room one side has two to re-lock, and by the locking of door lock screw and door lock screw mandrel and the locking of electromagnetic lock, whatsoever condition all can not be opened; When sterilization finished, operating personnel were when bacteria free room one side is opened hermatic door and taken out sterilizing article, and it is two to re-lock equally that bacterium chamber one side seal door is arranged, and whatsoever condition all can not be opened.By controlling the electromagnetic lock locked condition of two hermatic doors on the two-door sterilizer, can guarantee that have bacterium door and two hermatic doors of aseptic door of two-door sterilizer can not be opened simultaneously, satisfied instructions for use well.
