Description
Technical field
The utility model relates to a kind of Biohazard Safety Equipment of easy cleaning, in particular, relates in particular to the Biohazard Safety Equipment that a kind of forms have the easy cleaning of up-down and rotating function.
Background technology
When normal use Biohazard Safety Equipment is done related experiment, the inner negative pressure that forms of safety cabinet, air-flow air-inlet window in the past enters into cabinet inside; Pass through ventilating duct; Enter into the blower fan inlet scoop, blower fan promotes distribution of air flow and gives filter up and down then, and the air-flow of filter directly is discharged to indoor or outdoors on the process; Get into the operating space through the following air-flow of filter, converge into the process that one enters into next repetitive cycling with the air-flow of wind inlet.Different experiments need be used different experiment equipments and preparation, and also need water route, the gas circuit that have provide aqueous vapor to support experiment, and all use demand sides are to same problem: the cleaning of safety cabinet.
The forms of conventional security cabinet have two kinds of arrangement forms: a kind of is that glass guide-rail is fixedly mounted on the cabinet front, and glass moves up and down along the cabinet front in guide rail; When safety cabinet need clean, the peak that is raised on glass carried out the inner cleaning of cabinet; Yet the cleaning of safety cabinet glass inner side upper end; Cumbersome, need dismounting glass or cleanup crew inner at cabinet, glass all falls and could clean.No matter any clean method is as far as the client, all inconvenient; Safety cabinet glass inner side upper end becomes the cleaning dead angle of common safety cabinet.A kind of in addition is glass fixedly on the former frame, and forms can rotate and lift, but glass can not slide up and down; Thisly can clean cabinet and glass very easily; But after the operator finishes experiment, need other sealing frock sealing front window gathering hole, cause and use inconvenience.
Summary of the invention
The utility model provides a kind of forms to have the Biohazard Safety Equipment of the easy cleaning of up-down and rotating function in order to overcome the shortcoming of above-mentioned technical problem.
The Biohazard Safety Equipment of the easy cleaning of the utility model comprises cabinet and is arranged at the forms on the cabinet that forms are provided with vitreum; Its special feature is: said forms are provided with the lowering or hoisting gear that orders about vitreum and move up and down, the uplifting device and the control circuit part of ordering about the forms rotation; The connecting plate that uplifting device comprises the rotary shaft rack that is fixed on the cabinet, fix with forms and be connected rotary shaft rack and the connecting axle of connecting plate; Said lowering or hoisting gear has comprised the compoboard and the glass guide-rail that is arranged at the vitreum both sides of fixation; Be fixed with on the compoboard and promote motor, rely on and promote turning cylinder that motor drives and the two steel wire rope rollers that are individually fixed in the turning cylinder two ends; Two steel wire rope rollers are connected with vitreum through steel wire rope, and said turning cylinder is fixed on the compoboard through at least two spring bearings; Compoboard and connecting plate fix.
Vitreum is arranged on the forms, and vitreum has transparent effect, also can seal operating area.Compoboard plays fixing and supporting role, promotes motor and realizes the driving to turning cylinder, and spring bearing is realized the support to turning cylinder, and the steel wire rope roller is through ordering about vitreum to the winding of steel wire rope.Control circuit partly is used to control the running status that promotes motor, and the state of electrical equipment is detected, so that guarantee the operate as normal of lowering or hoisting gear and uplifting device.Drive vitreum through lowering or hoisting gear and move upward, can open the operating space of safety cabinet; Lowering or hoisting gear drives vitreum and moves downward, and can make the operating space of safety cabinet be in the good closed condition of sealing.Because the structure of lowering or hoisting gear all is arranged on the compoboard, and compoboard and connecting plate fix, so at connecting plate around the shaft in the support rotating process, forms are in the lifting state and whole lowering or hoisting gear also is lifted, lowering or hoisting gear can not carry out work.Like this, guaranteed convenience and the good sealing property that safety cabinet uses, guaranteed the convenience of vitreum inner surface cleaning through uplifting device through lowering or hoisting gear.
The Biohazard Safety Equipment of the easy cleaning of the utility model, said uplifting device comprise that also an end is fixed in the air spring that the other end and forms fix on the cabinet and supports.The supporting role that relies on air spring to support can guarantee that forms are in open mode all the time, are convenient to the cleaning glass body.
The Biohazard Safety Equipment of the easy cleaning of the utility model also is provided with the outer inclusion of guide rail on the said glass guide-rail, vitreum is provided with the slide block that matches with glass guide-rail and the outer inclusion of guide rail, and glass guide-rail is provided with the groove that matches with slide block.Glass guide-rail through with the cooperating of the outer inclusion of guide rail, form the U-lag that vitreum is led, can guarantee that vitreum rises stably and descends.
The Biohazard Safety Equipment of the easy cleaning of the utility model is provided with slide block on said Vitrea surfaces externally and internally and the side; The top of glass guide-rail, bottom and middle part all offer groove.On Vitrea surfaces externally and internally and side, slide block is set, can effectively reduces the frictional force of vitreum and guide rail, reduce running noises; Through cooperating of the groove on the glass guide-rail and slide block, can guarantee that vitreum has good sealing property.
The Biohazard Safety Equipment of the easy cleaning of the utility model, said lifting motor matches with the form of power transmission shaft with gears engaged; Steel wire rope roller place is provided with and is used for directive wheel that steel wire rope is led.Promote motor and pass through gear transmission mutually with turning cylinder, directive wheel is convenient to adjust the trend of steel wire rope.
The Biohazard Safety Equipment of the easy cleaning of the utility model, said Vitrea dual-side is provided with frame, and this frame is provided with and is used for the butt hook that is connected with steel wire rope.Frame and glassy phase are fixed, butt hook is fixed on the frame, have so just realized being connected of steel wire rope and steel wire rope roller.
The Biohazard Safety Equipment of the easy cleaning of the utility model, said control circuit partly comprise being used to detect the limit switch of steel wire rope tensioning state and detecting vitreum whether be in travel switch bottom.Limit switch is through to the detection of steel wire rope tensioning state, and it is undesired when loosening to occur as steel wire rope, and order out of service promote motor.Travel switch produces action when vitreum runs to bottom, the rotation of lifting motor can only be rotated to direction of improvement, and the steel wire rope of having avoided motor to be rotated further causing twines problem.
The beneficial effect of the utility model is: the Biohazard Safety Equipment of the utility model is through be arranged on lowering or hoisting gear and uplifting device on the forms simultaneously; Realized that the rotation of Vitrea oscilaltion and forms lifts; Both guarantee the convenience of safety cabinet use and the excellent sealing property of operating space, also guaranteed the convenience of vitreum inner surface in wiping process.The operator can clean cabinet and vitreum very easily, and does not have the cleaning dead angle; And do not need other sealing frocks, change can seal suction inlet, prevents to pollute the cabinet internal environment, has greatly made things convenient for operator's operating process.Through slide block being set on the vitreum and groove being set on guide rail, reduced frictional resistance and noise when vitreum goes up and down effectively, more convenient to use.
