It is pumped into close to can be especially laborious when vacuum in small establishments space.Vaccum-pumping equipment is usually required, but these these equipment are generally thrown
Enter all bigger, economy is not high, and due to limited in space, some places can only use small-sized hand-operated pumping drawing liquid
Device.
Utility model content
The purpose of this utility model is to provide a kind of saving hands to be evacuated pumping device, which can easily realize
Drawing liquid or pumping operation, and then improve work efficiency, while the labor intensity of operating personnel is also reduced, it plays laborsaving
Purpose.
In order to realize above-mentioned technical characteristic, what the purpose of this utility model was realized in：A kind of saving hand pumping
Pumping device, it includes cylinder body, and the inside of the cylinder body is equipped with piston, and piston rod is connected on the piston,
One end of the piston rod stretches out cylinder ontology is equipped with spring, the other end of the spring be fixed on consolidating for piston-rod end
Fixed board contacts；The head of the piston is provided with sealing ring；The head of the cylinder body is provided with outlet part；In cylinder body
Head on both sides wall on be symmetrically arranged with otic placode, the manual inflation for pushing piston is hinged between the otic placode and fixed plate
Operating mechanism.
The circumference of the piston is provided with multi-turn nylon6 chips, and the inner wall of the nylon6 chips and cylinder body is engaged.
The manual charge operation mechanism includes handle, and one end of the handle is hinged on by the first axis pin on otic placode,
Sliding slot is machined in the middle part of handle, being slidably installed on the sliding slot has sliding pin, and the sliding pin is hinged on one end of connecting rod,
The other end of the connecting rod is hinged by the second axis pin and fixed plate.
Another end of the handle is set with rubber sleeve.
The utility model has the advantages that：
1, by using above-mentioned device, when being pulled out by handle band piston, the air pressure of the device intracavitary is less than outside
Air pressure, there are pressure differences, force atmospheric pressure by liquid or gas indentation cylinder chamber, realize air-breathing.When handle band piston pushes away
Into when, cylinder cavity space becomes smaller, air pressure inside be more than external pressure, realize exhaust.And then realize the work(of pumping or imbibition
Energy.
2, above-mentioned apparatus is simple in structure, small, light-weight, easy to carry, at low cost, easy to use, can answer extensively
The occasion for being pumped into nearly vacuum is needed for laboratory and research field.
3, by the way that in the manual charge operation mechanism course of work, labour-saving can be played the role of, pass through lever original
Reason greatly saves the power that power is applied in operation.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is that the utility model arranges installation diagram on single residential building.
In figure：Sealing ring 1, spring 2, the second axis pin 3, connecting rod 4, sliding pin 5, sliding slot 6, rubber sleeve 7, nylon6 chips 8, first are sold
Axis 9, piston 10, piston rod 11, cylinder body 12, outlet part 13, fixed plate 14, otic placode 15, handle 16.
Specific implementation mode
The embodiment of the utility model is described further below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of saving hand is evacuated pumping device, it includes cylinder body 12, the cylinder body 12
Inside is equipped with piston 10, and piston rod 11, one end of 11 stretches out cylinder ontology 12 of the piston rod are connected on the piston 10
Spring 2 is installed, the other end of the spring 2 is contacted with the fixed plate 14 for being fixed on 11 end of piston rod；The piston 10
Head is provided with sealing ring 1；The head of the cylinder body 12 is provided with outlet part 13；In the head on both sides wall of cylinder body 12
On be symmetrically arranged with otic placode 15, the manual charge operation for pushing piston 10 is hinged between the otic placode 15 and fixed plate 14
Mechanism.It, can be with piston 10, Jin Ertong by manual charge operation mechanism in the course of work by using above-mentioned device
Piston 10 is crossed in 12 internal motion of cylinder body, pumping or the work of drawing liquid are realized by the variation of air pressure.
Further, the circumference of the piston 10 is provided with multi-turn nylon6 chips 8, the nylon6 chips 8 and cylinder body 12
Inner wall is engaged.Good sealing effect is played by the multi-turn nylon6 chips 8.
Further, the manual charge operation mechanism includes handle 16, and one end of the handle 16 passes through the first axis pin 9
It is hinged on otic placode 15, is machined with sliding slot 6 at the middle part of handle 16, being slidably installed on the sliding slot 6 has sliding pin 5, described
