Description
Technical field
This utility model relates to the upper box lowering or hoisting gear of a kind of positive/negative-pressure fowl isolator, belongs to medical experiment equipment technical field.
Background technology
At present, in medical treatment zoopery, the upper box of widely applied isolator separates with lower box or utilizes artificial by upper box
Carry off, thus the mode that isolator inside is cleared up, the separate mode of this isolator upper box and lower box be primarily present with
Lower problem: one is that hand labor intensity is big；Two is the bigger working place needed；Three is single to complete.Therefore, this point
In experimentation, bigger puzzlement is caused to experimenter from mode.
Summary of the invention
According to above deficiency of the prior art, problem to be solved in the utility model is: provide a kind of simple in construction, and design is closed
Reason, low cost, it is not necessary to bigger work space, reduces hand labor intensity, single can complete the positive/negative-pressure fowl isolator of operation
Upper box lowering or hoisting gear.
This utility model solves its technical problem and be the technical scheme is that
The upper box lowering or hoisting gear of described positive/negative-pressure fowl isolator is logical including upper box and lower box, upper box and lower box one end
Cross chain connection, upper box and the lower box other end install air spring and snap close, and lower box top is provided with matches with upper box
Sealing ring.
The upper box lowering or hoisting gear of described positive/negative-pressure fowl isolator passes through air spring and the cooperation of hinge, makes upper box and lower box real
The unlatching of existing certain angle, facilitates staff to operate isolator inside, the single separation that just can complete lower box,
Reduce the labor intensity of staff, and without extra workspace, simple in construction, easy to use.
Preferred further, air spring arranges two and is separately mounted to upper box and lower box both sides.The good stability supported.
Preferred further, hinge arranges three, is set in qually spaced in one end of upper box and lower box.
Preferred further, air spring uses self-locking air spring or balanced type air spring.Can select the most flexibly.
Preferred further, the installing hole that upper box lower outside and lower box upper outside are respectively arranged with air spring two ends matches
The fixed installation axle closed, air spring is arranged on fixed installation axle, arranges nut assembly outside fixed installation axle.Simple in construction, peace
Dress is convenient.
Preferred further, hinge includes that top connecting plate and lower connecting plate, top connecting plate and lower connecting plate pass through connecting shaft
Connect.Top connecting plate connects upper box, and lower connecting plate connects lower box, easy for installation.
This utility model is had the beneficial effect that
The upper box lifting device structure of described positive/negative-pressure fowl isolator is simple, reasonable in design, easy to use, by air spring and
The cooperation of hinge, the single separation that just can complete lower box, greatly reduce the labor intensity of staff, it is not necessary to extra work
Make space, there is stronger practicality.

Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further:
As shown in figs 1 to 6, the upper box lowering or hoisting gear of positive/negative-pressure fowl isolator described in the utility model, including upper box 1 and under
Casing 4, upper box 1 and lower box 4 one end are connected by hinge 5, and hinge 5 arranges three, is set in qually spaced in upper box 1 and nowel
On body 4, upper box 1 and lower box 4 other end install air spring 2 and snap close 3, and air spring 2 arranges two and is separately mounted to upper box
1 and lower box 4 both sides, air spring 2 uses self-locking air spring or balanced type air spring, lower box 4 top to be provided with and upper box 1
The sealing ring 6 matched.
As Figure 3-Figure 4, upper box 1 lower outside and lower box 4 upper outside are respectively arranged with and the installing hole at air spring 2 two ends
The fixed installation axle 7 matched, air spring 2 is arranged on fixed installation axle 7, arranges nut assembly 8 outside fixed installation axle 7.
As shown in Figure 6, hinge 5 includes that top connecting plate 9 and lower connecting plate 10, top connecting plate 9 and lower connecting plate 10 are by even
Spindle 11 connects, and top connecting plate 9 connects upper box 1, and lower connecting plate 10 connects lower box 4.
Operation principle of the present utility model and the process of use:
The upper box lowering or hoisting gear of positive/negative-pressure fowl isolator described in the utility model is when isolator opened by needs, by isolator edge
Open for locking the snap close 3 of upper box 1 and lower box 4, lift isolator upper box 1 to maximum angle of release, supported by air spring 2,
Isolator inside can be carried out the operations such as cleaning.When needing to close isolator, upper box 1 to the upper box 1 of drop-down isolator and under
Casing 4 fully seals, and locks snap close 3 and can realize the airtight of isolator upper box 1 and lower box 4.This utility model simple in construction,
Reasonable in design, easy to use, the single separation that just can complete lower box, greatly reduce the labor intensity of staff, nothing
Need extra workspace, there is stronger practicality.
