Embodiment
The utility model proposes a kind of automatic landing-gear for cabinet door of divulging information.
Reference picture 1-2, Fig. 1 are the structural representation of vent cabinet, and Fig. 2 is the structure of automatic falling device in first embodiment
Schematic diagram.
As shown in Figure 1-2, in the utility model embodiment, the vent cabinet includes：Cabinet door 1 of divulging information and front plaquette 2, should
Front plaquette 2 is located at the front upper of vent cabinet.As shown in Fig. 2 the automatic landing-gear includes：Set up separately located at vent cabinet inner chamber
The first gear of upper wall, second gear, the 3rd gear and the 4th gear, first gear are coaxially disposed with second gear, and point
Above the both sides for the cabinet door 1 that Wei Yu not divulge information, the 3rd gear is coaxially disposed with the 4th gear, and is located at vent cabinet rear portion both sides respectively
Upper wall.The first chain 31 is provided between first gear and second gear, the second chain is provided between second gear and the 3rd gear
Bar 32.First chain 31 is connected with both sides upper end of the first end of both the second chains 32 respectively with cabinet door 1 of divulging information, the first chain
31 are connected balance weight respectively with the second both the second ends of chain 32.The weight of the weight sum of two balance weights and ventilation cabinet door 1
It is equal.As shown in figure 3, each balance weight includes the first balance weight iron 41 and the second balance weight iron 42, the first balance weight iron 41 and
Connection chain 43 is provided between two balance weight irons 42.
In the present embodiment, first gear, second gear, the 3rd gear, the 4th gear are Bearing gear.In vent cabinet
Chamber upper wall is provided with and first gear, second gear, the 3rd gear, the one-to-one fulcrum bearing 5 of the 4th gear, first gear, the
Corresponding fulcrum bearing 5 is rotatably assorted respectively for two gears, the 3rd gear, the 4th gear.Specifically, first gear, second gear,
3rd gear, the 4th gear are Bearing gear, and Bearing gear rotates flexible, Jing Yin, service life length.Fulcrum bearing 5 is by high-strength
Degree aluminium alloy is made, and the load-bearing of fulcrum bearing 5 is good made of high-strength aluminum alloy, high with the fit precision of Bearing gear.
In the present embodiment, the face on the basis of the work top of the upper wardrobe body of vent cabinet, the bottom surface of front plaquette 2 and the benchmark
Spacing between face is 800mm, and ventilation cabinet door 1 can move between the bottom surface of the reference plane and front plaquette 2.Connect chain 43
Length is 150mm, and it is significantly less weight than the weight sum of the first balance weight iron 41 and the second balance weight iron 42, thus its for balance weight iron with
The influence of balance between ventilation cabinet door 1 is ignored.
As shown in Fig. 2 cabinet door 1 of divulging information is pushed to the bottom surface of front plaquette 2 so that the first balance weight iron 41 and the second balance weight iron
42 drop to the surface residing for the work top of vent cabinet, and when experimenter looses one's grip, ventilation cabinet door 1 is made in the weight of itself
With decline, when the height for cabinet door 1 of divulging information is between 650mm~800mm, due to connecting the relation of chain 43, in the section
Second balance weight iron 42 is not connected chain pull-up, is still held by work top.And the weight of the first balance weight iron 41 is less than ventilation
The weight of cabinet door 1, therefore cabinet door 1 of divulging information can still decline with gravity.As shown in figure 3, when the height of ventilation cabinet door 1 is in 650mm
During position, the second balance weight iron 42 is connected chain 43 and sling, so that the weight at the both ends of two first chain 31 reaches balance, leads to
Wind cabinet door 1 hovers over 650mm height, so as to protect the face of behaviour experimenter and upper area.
Balance weight is divided into the first balance weight iron 41 and second by technical solutions of the utility model by changing the structure of balance weight
Balance weight iron 42, then be attached the first balance weight iron 41 and the second balance weight iron 42 by the connection chain 43 with certain length.
So, only when the first balance weight iron 41 and the second balance weight iron 42 are all lifted, balance weight can keep flat with ventilation cabinet door 1
Weighing apparatus.Wherein, the length for connecting chain 43 can be as the height that ventilation cabinet door 1 is fallen automatically.Experimenter only need to be by vent cabinet
Door 1 is pushed into top, relief vent cabinet door 1 voluntarily drop down onto suitable height (height connects the length of chain 43) down, i.e.,
Can in experimentation the face of Protection personnel and upper area.It should be noted that the length of connection chain 43 can root
It is adjusted according to the height of the action pane of vent cabinet.Compared with prior art, the beneficial effects of the utility model are：Without real
Test personnel and adjust the height of ventilation cabinet door 1 manually and come the face of Protection personnel, avoid experimenter in experimentation with
The direct contact for cabinet door 1 of divulging information, reduce experimenter and operate inconvenience and contact the operation hidden danger brought with ventilation cabinet door 1.
Preferably, couple axle 6 is provided between second gear and second gear so that first gear and second gear couple axle
6 connections formed it is synchronous, so as to realize the left and right synchronous balance lifting of ventilation cabinet door 1 so that ventilation cabinet door 1 lift it is more steady,
It is light.
As shown in figure 3, in second embodiment of the present utility model, the bottom surface of front plaquette 2 is provided with the first magnet.Vent cabinet
The lower end of door 1 is provided with the second magnet 7 being engaged with the first magnet, and the positive pole of the second magnet 7 is relative with the negative pole of the first magnet.
Pass through the first magnet and the magneticaction of the second magnet 7 so that ventilation cabinet door 1 can be fixed on front plaquette when being pushed into top
2 bottom, in order to install, dismantle large scale equipment.
Preferred embodiment of the present utility model is these are only, not thereby limits the scope of the claims of the present utility model, it is every
Under inventive concept of the present utility model, the equivalent structure transformation made using the utility model specification and accompanying drawing content, or
Directly/be used in other related technical areas indirectly and be included in scope of patent protection of the present utility model.
