Abstract

The utility model relates to an ultraviolet ray disinfecting transmission window. The utility model is characterized in that two doors of the transmission window are provided with a set of mutual interlocking gear; the mutual interlocking gear interacts opening or closing of the two doors; the two doors are respectively provided with indicator lights, and one indicator light indicates opening or closing state of the other door. The mutual interlocking gear is composed of two electric magnets and a set of 24V direct current power supply, wherein, the two electric magnets are respectively connected with two microswitches in series; the direct current power supply make the electric magnets work. The opening or closing state of the two doors controls the microswitches, and the microswitches control the electric magnets. The electric magnets drive a locking pin to fit with a keyhole of one door, and thereby, the utility model realizes interlock of the two doors.

Description

Ultra-violet ray disinfecting transmission window

This utility model belongs to uses ultraviolet radiation sterilization and the equipment of sterilizing.Be particularly related to a kind of ultraviolet disinfection pass-through box.

Extraneous or through in the experiment utensil of sterilization and the laboratory that laboratory sample is delivered to sterilization, need by the ultraviolet disinfection pass-through box, and there is following defective in the existing ultraviolet disinfection pass-through box that adopts: its two side doors are free switch, and in case when its two side doors that are contained in bacterium and sterilizing room are respectively opened simultaneously, certainly will cause the aseptic experiment chamber contaminated.

The purpose of this utility model is exactly will overcome the deficiencies in the prior art and a kind of have bacterium chamber and the interlockable ultraviolet disinfection pass-through box of sterilizing room two side doors are provided.

This utility model is design like this: it is characterised in that is equipped with a cover mutual interlocking gear on sterilization pass-through box two side doors, mutual restriction the unlatching of two side doors, and respectively the opening that display lamp is indicated another side door is housed in both sides.When the door of bacterium chamber was opened, the door of sterilizing room was promptly by locked, and only after having bacterium chamber door to shut, the door of sterilizing room can be opened, and vice versa.Mutual interlocking gear is being connected in series two microswitch respectively by two electric magnet and a cover provides the 24V dc source of work of electromagnet to form.On off state by two side doors is being controlled microswitch, is controlling electric magnet by microswitch, by electric magnet drive lock pin with on keyhole cooperate, realize the interlocking of two side doors.

This utility model compared with prior art its advantage is that it has solved original pass-through box two side doors and does not have control, free switch and easily cause clean indoor air environment pollution problems, the duty indication that increases, can make user recognize the residing state of pass-through box at a glance, and needn't worry that the situation that two side doors are opened simultaneously takes place.

Fig. 2 is this utility model mutual interlocking gear structural representation;

Fig. 3 is this utility model mutual interlocking gear electrical schematic diagram;

Provide embodiment of the present utility model below in conjunction with accompanying drawing.

This utility model is made up of casing, uviol lamp, mutual interlocking gear, as shown in Figure 1, casing is a double-decker, between door 12 and case internal layer 9, be embedded with sealing strip 8, leave the space between the skin 10 of casing one end and the internal layer 9, in order to settling electric magnet 4,14, mains transformer 5, uviol lamp ballast 6, and all be equipped with interlocking display lamp 1 and uviol lamp display lamp and switch 2 in the casing both sides.Mutual interlocking gear of the present utility model is by two electric magnet 4,14 are being connected in series two microswitch 15 respectively, 16 and provide the 24V dc source of work of electromagnet to form, as Fig. 1, shown in 2, two electric magnet 4,14 are placed in the unlatching limit of pass-through box two side doors respectively, all have lock pin 4 on each electric magnet, be with back-moving spring 13 on the lock pin 4, on corresponding door limit, the keyhole 7 that cooperates with lock pin is arranged, as shown in Figure 3, two microswitch 15,16 have 4 binding posts respectively, be binding post A1, binding post A2, binding post A3, binding post A4 and binding post B1, binding post B2, binding post B3, binding post B4, binding post A4 links to each other with binding post B1, binding post A2 links to each other with binding post B3, binding post A3 and binding post B4 connect the positive terminal of 24V power supply, binding post A1 and binding post B2 connect an electric magnet 4 respectively, 14, two electric magnet 4, the negative pole end of 14 the other end and 24V power supply joins, and distinguishes display lamp 1 in parallel on two electric magnet.Switch 15 and 16 is connected binding post A1-A2, B1-B2 respectively when the Men Jun of bacterium chamber one side and sterilizing room one side closes, and binding post A3 and A4, B3 and B4 then disconnect, and then electric magnet 4 and 14 all is in and treats duty.When the door of bacterium chamber one side was opened, switch 15 was upspring binding post A1 and A2 is disconnected, and binding post A3 and A4 are connected, and so just made electric magnet 14 energisings, and it is dead the door lock of sterilizing room that electric magnet 14 adhesives drive its lock pin, and the display lamp 1 of this side is bright simultaneously.When sterilizing room one side is opened the door when getting article, switch 16 is connected binding post B3 and B4 again, then make electric magnet 4 energisings, electric magnet 4 adhesives drive the door lock dead (as shown in Figure 2) that its lock pin 3 will have the bacterium chamber, there is the display lamp 1 of bacterium chamber one side to light, has this moment the door of bacterium chamber one side also can't open.So just guaranteed article from there being the bacterium chamber to be sent to the process of sterilizing room, it is isolated all the time that bacterium chamber and sterilizing room are arranged, and this just makes the external world have the collarium border can not have influence on working environment in the sterilizing room.

As shown in Figure 1, inner chamber top plate dress uviol lamp of the present utility model place has groove, and the both sides of groove are the slope at band α angle, uviol lamp 11 is contained in the groove, avoided bumping brokenly uviol lamp 11 when transmitting article, the size at α angle is as the criterion not form lighting dead angle according to the size of casing.

Claims (2)

1, a kind of ultraviolet disinfection pass-through box, its casing is a double-decker, the casing both sides have door, uviol lamp is placed on the cabinets cavity top plate, it is characterized in that it has a cover mutual interlocking gear, mutual interlocking gear is being connected in series two microswitch respectively by two electric magnet and is providing the 24V dc source of work of electromagnet to form, two electric magnet are placed in the unlatching limit of pass-through box two side doors respectively, all have lock pin on each electric magnet, be with back-moving spring on the lock pin, on corresponding door limit, the keyhole that cooperates with lock pin is arranged, it is binding post A1 that two microswitch have 4 binding posts respectively, binding post A2, binding post A3, binding post A4 and binding post B1, binding post B2, binding post B3, binding post B4, binding post A4 links to each other with binding post B1, binding post A2 links to each other with binding post B3, binding post A3 and binding post B4 connect the positive terminal of 24V power supply, binding post A1 and binding post B2 connect an electric magnet respectively, the negative pole end of the other end of two electric magnet and 24V power supply joins, and distinguishes display lamp in parallel on two electric magnet.

2, ultraviolet disinfection pass-through box according to claim 1 is characterized in that having one to be with the groove on slope at cabinets cavity top plate dress uviol lamp place, and uviol lamp places in the groove on band slope.
