Description
Technical Field
The utility model provides an installation mechanism convenient to biological safety cabinet changes high efficiency filter belongs to biological safety cabinet equipment technical field.
Background
The conventional biological safety cabinet is installed the high efficiency filter in the workspace top earlier, then places the static pressure case in the high efficiency filter top, but the high efficiency filter needs to be changed after using a certain time, this has just caused when changing the high efficiency filter, just must lift the static pressure case earlier then can take out the problem that the high efficiency filter changed, because the static pressure case is bulky and heavier, need two people at least to lift it out, it is very inconvenient to operate, and consuming time and wasting power.
SUMMERY OF THE UTILITY MODEL
In order to satisfy the actual demand under the current background art, the utility model aims at providing a be convenient for biosafety cabinet changes high efficiency filter's installation mechanism, but the device convenient and fast changes high efficiency filter.
In order to realize the above purpose, an installation mechanism convenient to biosafety cabinet changes high efficiency filter, including the biosafety cabinet, be equipped with the workspace in the biosafety cabinet, the workspace top is equipped with high efficiency filter, and the static pressure case is placed in high efficiency filter top, static pressure case top is equipped with connecting device, be equipped with fixing device on the biosafety cabinet inside wall, be equipped with hoisting device between connecting device and the fixing device.
Preferably, the connecting device adopts two lifting lugs arranged at two ends of the static pressure box, the fixing device adopts two supporting frames arranged on the inner wall of the biological safety cabinet, and the lifting device adopts a screw rod.
Preferably, a nut matched with the screw rod is arranged below the lifting lug, the screw rod base is clamped above the support frame, and the screw rod penetrates through the support frame and the lifting lug to be connected with the nut.
The utility model discloses beneficial effect:
the utility model discloses simple structure utilizes the rotatory lift of screw rod, and when the effectual high efficiency filter that has solved was changed, still need the condition of lifting out the static pressure case to can operate alone, only need rotate the screw rod of both sides with the spanner and just can take out high efficiency filter and change, great improvement efficiency, practiced thrift the manpower, and change very easily.
Drawings
FIG. 1 is a front view of the utility model;
fig. 2 is a side view of the present invention;
fig. 3 is a top view of the present invention;
in the figure: 1. lifting lugs; 2. a screw; 3. a support frame; 4. a screw base; 5. a nut; 6. a biological safety cabinet; 7. a static pressure box; 8. a high-efficiency filter.
Detailed Description
Example 1:
referring to the attached drawings of the specification, the installation mechanism convenient for replacing the high-efficiency filter of the biological safety cabinet comprises a biological safety cabinet 6, a working area is arranged in the biological safety cabinet 6, the high-efficiency filter 8 is arranged above the working area, and the static pressure box 7 is placed above the high-efficiency filter 8.
The connecting device adopts two lifting lugs 1 arranged at two ends of the static pressure box 7, the fixing device adopts two supporting frames 3 arranged on the inner wall of the biological safety cabinet 6, and the lifting device adopts a screw rod 2.
The screw rod 2 penetrates through the support frame 3 and the lifting lug 1 to be connected with the nut 5.
The static pressure box 7 is an air storage box inside the biological safety cabinet 6, and air flow enters the static pressure box 7 through a fan and then enters a working area through a high-efficiency filter 8 below the static pressure box 7, so that the aim of purifying the working area is fulfilled. The utility model discloses an add lug 1 at static pressure case 7 both ends, be connected with screw rod 2 and biosafety cabinet 6's lateral wall support frame 3, reach the purpose that promotes static pressure case 7 through the rotation of screw rod to high efficiency filter 8 can directly be taken out from static pressure case 7 below, then change. This structure is easy and simple to handle, and very big has made things convenient for the change flow, the operation that needs two talents to accomplish at least before, can operate alone now, only need rotate the screw rod 2 of both sides with the spanner and just can take out high efficiency filter 8 and change, great saving manpower to it is very light to change.
