Have and air draft region through hole on the side plate of mouth.During pass-through box work, circulating fan is sent into after high efficiency particulate air filter filters
Clean gas flow sprays to delivery areas goods, effectively and rapidly removes dust particle, and the dust particle after removing enters air draft
Region, then after being filtered by high efficiency particulate air filter, be re-circulated in delivery areas, so circulate, reach independent loops air-supply, self-cleaning
Beneficial effect.But, doorframe of the prior art is to use sealing strip and transmission window flat seal, this sealing effectiveness meeting
Owing to the contact of sealing strip is uneven or deformation produces gap, affect cleaning effect；And use the circulation to pass-through box delivery areas
Air intake and air discharge structure, remain dust particle removing after entering into delivery areas, there is the halfway problem of removing.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of pass-through box doorframe structure, uses to seal and prevents at window
Only dust particle enters in delivery areas, make the small article between clean area and non-clean area in transmittance process, will not
Produce the pollution to delivery areas, it is ensured that the cleaning effect of pass-through box.
This utility model realizes above-mentioned purpose by the following technical solutions.With the pass-through box of negative pressure doorframe, including transmission
Forms, door lock and be arranged on the doorframe that transmission forms two ends window is split, described door lock includes that hands is, lock and snap close, hands handle
Being fixedly installed on lock, snap close is fixedly installed in the housing of transmission forms two ends window, and the front end of hands handle is provided with bayonet socket, card
Mouth matches with snap close；Being provided with the lock of door lock outside described doorframe, doorframe is built with windowpane, the two of described transmission forms
End window is provided with inside casing, and inside casing is hollow structure, and the outside of inside casing is provided with groove, and the bottom of groove is provided with suction hole；
Being provided with sealing strip inside the framework of described doorframe, sealing strip is corresponding with groove；Described the installed above of transmission forms has air-breathing
Mouth, one end of vacuum noz(zle) is connected with inside casing, and the other end of vacuum noz(zle) is connected with vacuum pump.
Further, the front end bayonet socket of described hands handle is provided with fixture block and jacking block.
Further, the side of described snap close is provided with flat surface and sloping platform face, and flat surface is connected with sloping platform face and two planes
Angle be 150 °.
Further, in described fixture block is installed in snap close locked groove.
Further, described jacking block peaks in flat surface.
This utility model makes sealing strip periphery constitute lower negative pressure convulsion, and in pass-through box body, the groove of frame can hold doorframe
Peripheral seal；Simultaneously when opening doorframe placing articles, external dust particle can be sopped up, no by negative pressure convulsion by vacuum noz(zle)
Can be brought in pass-through box body region, it is therefore prevented that the pollution in transmittance process between clean area and non-clean area, be greatly improved
The cleaning effect of pass-through box.

Detailed description of the invention
In conjunction with drawings and Examples, the utility model is described in further detail.See Fig. 1 to Fig. 8, with negative pressure doorframe
Pass-through box, including transmission forms 1, door lock 4 be arranged on the doorframe 2 that transmission forms 1 two ends window is split, described door lock 4 wraps
Including hands 41, lock 42 and snap close 43, hands are fixedly installed on lock 42 41, snap close 43 is fixedly installed in transmission forms 1 liang
The housing of end window, hands is provided with bayonet socket the front end of 41, and bayonet socket matches with snap close 43；Outside described doorframe 2, door is installed
The lock 41 of lock 4, doorframe 2 is built with windowpane 3, and the two ends window of described transmission forms 1 is provided with inside casing 11, during inside casing 11 is
Hollow structure, as shown in Figures 2 and 3, the outside of inside casing 11 is provided with groove 12, and as shown in Figure 4 and Figure 5, the bottom of groove 12 sets
It is equipped with suction hole 121；Sealing strip 22, as shown in Figure 6, sealing strip 22 and groove 12 are installed inside the framework 21 of described doorframe 2
Corresponding；The installed above of described transmission forms 1 has vacuum noz(zle) 5, and one end of vacuum noz(zle) 5 is connected with inside casing 11, another of vacuum noz(zle) 5
End is connected with vacuum pump.As it is shown in fig. 7, described hands is provided with fixture block 411 and jacking block 412 the front end bayonet socket of 41.Such as Fig. 7 and
Shown in Fig. 8, the side of described snap close 43 is provided with flat surface 431 and sloping platform face 432, flat surface 431 be connected with sloping platform face 432 and
The angle β of two planes is 150 °.Described fixture block 411 is installed in snap close 43 locked groove.Described jacking block 412 peaks in flat surface 432.
This utility model, with the pass-through box of negative pressure doorframe, is provided with door lock 4, transmission forms 1 two ends window outside doorframe 2
Housing snap close 43 is installed, the two ends window of transmission forms 1 is provided with the inside casing 11 of hollow structure, and the outside of inside casing 11 is arranged
Fluted 12, the bottom of groove 12 is provided with suction hole 121；The inside casing 11 of hollow structure is carried out by vacuum pump by vacuum noz(zle) 5
Lower negative pressure is bled, and makes the suction hole 121 of inside casing 11 produce lower negative pressure, it is thus possible to the negative pressure convulsion when opening doorframe 2 placing articles
By suction hole 121, external dust particle is sopped up, will not be brought in pass-through box body region.When closing doorframe 2, fixture block
411 snap in snap close 43, make doorframe 2 lock.Meanwhile, suction hole 121 holds sealing strip 22, can improve the sealing effect of sealing strip 22
Really.When doorframe 2 opened by needs, jacking block 412 peaks in flat surface 432, and the hands of pulling door lock 4,41, makes jacking block 412 pass through
The counteracting force in sloping platform face 432 pushes doorframe 2 open, offsets suction hole 121 and holds the negative pressure of sealing strip 22, it is achieved door lock 4 is light
Open.
