To achieve the above object, present invention employs following technical scheme：Including supporting table and it is arranged on above supporting table
And the objective table parallel with supporting table, the telescoping tube of both connections is equipped between the supporting table and objective table, it is described
Telescoping tube is connected with tracheae, and tracheae is equipped with pressure charging valve and relief valve, flexible tube cavity, tracheae, pressure charging valve and the pressure release
Closed cavity is formed between valve, telescoping tube is when tracheae is inflated in the upward stretched condition for jacking up objective table, and telescoping tube is in gas
In the downward contraction state for withdrawing objective table when pipe is deflated, the telescoping tube is incremented by successively by diameter from up to down and can be according to
Secondary nested multiple annular pipeloop compositions, the annular pipeloop include spaced apart hard ring pipe and soft ring pipe,
Two annular pipeloops being connected with objective table and supporting table are hard ring pipe, between telescoping tube and supporting table and objective table,
It is each annular pipeloop between be seamlessly connected, the diameter of hard ring pipe upper and lower port is identical, soft ring pipe upper port it is straight
Footpath is less than the diameter of lower port, and the annular gap formed between adjacent two hard ring pipe is used for accommodating between two hard ring pipes
Soft ring pipe, between the supporting table and objective table set a telescoping tube, the tracheae include first, second
Pipe, one end of first pipe are connected with pressure charging valve, the other end of first pipe and the hard ring pipe of telescoping tube bottom
Connection, one end of second pipe are connected with relief valve, the other end of second pipe and the hard annular of telescoping tube bottom
Pipe connects, and the pressure charging valve and relief valve are equipped with the handle or foot pedal for controlling its break-make.
As shown from the above technical solution, for the present invention using power source of the air pressure increase and decrease as lifting platform, being aided with can be with air pressure
Change and the telescoping tube upholding or shrink realizes the lifting of cargo, have simple in structure, cost is low, energy consumption is small, lifting is steady,
The advantages of safe.
Brief description of the drawings
Fig. 1 is the structural front view of the embodiment of the present invention one；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is the front view of the embodiment of the present invention two；
Fig. 4 is the top view of Fig. 2.
Embodiment
The present invention will be further described below in conjunction with the accompanying drawings：
A kind of lifting platform as shown in Figure 1, Figure 3, including supporting table 1 and be arranged on the top of supporting table 1 and with 1 phase of supporting table
Parallel objective table 2, is equipped with the telescoping tube 3 of both connections between supporting table 1 and objective table 2, telescoping tube 3 is connected with tracheae, gas
Pipe is equipped with pressure charging valve 4 and relief valve 5, forms closed cavity between 3 inner cavity of telescoping tube, tracheae, pressure charging valve 4 and relief valve 5, stretches
The draw 3 is received in the upward stretched condition for jacking up objective table 2, telescoping tube 3 when tracheae is inflated when tracheae is deflated in downwards
Return the contraction state of objective table 2.
Further, telescoping tube 3 is incremented by successively by diameter from up to down and nested multiple annular pipeloops can form successively,
Annular pipeloop includes spaced apart hard ring pipe 31 and soft ring pipe 32, two to be connected with objective table 2 and supporting table 1
Annular pipeloop is hard ring pipe 31, that is, two ends of telescoping tube are hard ring pipe, telescoping tube 3 and supporting table 1
And between objective table 2, between each annular pipeloop be to be seamlessly connected.
Further, illustrated so that the diameter of telescoping tube incrementally designs from up to down as an example：Telescoping tube 3 is straight from up to down
Footpath is incremented by, and the diameter of 31 upper and lower port of hard ring pipe is identical, and the diameter of soft 32 upper port of ring pipe is less than the straight of lower port
Footpath, that is, hard ring pipe are isodiametric ring pipe, and soft ring pipe is then the ring pipe of variable diameters, soft ring pipe
The diameter of upper port should match with the diameter of the hard ring pipe above it, it is soft annular infratubal port diameter should with it
The diameter of the hard ring pipe of side matches, and the annular gap formed between adjacent two hard ring pipe 31 is used for accommodating two hard
Soft ring pipe 32 between ring pipe 31.When tracheae is inflated, soft ring pipe will bulging objective table is lifted, work as tracheae
During deflation, soft ring pipe is shunk, and hard ring pipe just nests together successively from top to bottom, and objective table declines at this time.
Further, pressure charging valve 4 and relief valve 5 are equipped with the handle or foot pedal for controlling its break-make.Namely operation increases
The handle or foot pedal of pressure valve can realize tracheae air inlet, and the handle or foot pedal for operating relief valve can realize putting for tracheae
Gas.Further, pressure charging valve can also be replaced with electric inflation pump.
Embodiment one：
As shown in Figure 1 and Figure 2, a telescoping tube 3 is set between supporting table 1 and objective table 2.
In the case where setting a telescoping tube, tracheae includes first, second pipe 6,7, one end of the first pipe 6 and pressure charging valve
4 are connected, and the other end of the first pipe 6 is connected with the hard ring pipe 31 of 3 bottom of telescoping tube, one end and the relief valve 5 of the second pipe 7
It is connected, the other end of the second pipe 7 is connected with the hard ring pipe 31 of 3 bottom of telescoping tube.What is be namely connected with supporting table is hard
First, second pipe is directly connected with the tube wall of matter ring pipe, pressure charging valve, relief valve, telescoping tube and first, second pipe form close
The cavity closed.
Embodiment two：
As shown in Figure 3, Figure 4, four telescoping tubes 3 are uniformly arranged between supporting table 1 and objective table 2.
In the case where setting four telescoping tubes, supporting table 1 is equipped with four connected respectively with four 3 inner cavities of telescoping tube
Circular hole 11, it is preferred that four circular holes should be arranged concentrically with four telescoping tubes, and tracheae includes being respectively communicated with the connection of four circular holes 11
Pipe 8, connecting tube 8 are arranged on inside supporting table 1, that is, are connected four circular holes by four connecting tubes 8 in the inside of supporting table
Logical, four circular holes are connected with the inner cavity of four telescoping tubes again, and connecting tube 8 is equipped with pressure charging valve 4 and relief valve 5, that is, is pressurized
Valve 4 is connected by pipeline and connecting tube again with relief valve 5.
The course of work of the present invention is as follows：
When needing to lift weight, weight is placed on objective table, the handle or foot pedal of attended operation pressure charging valve are to close
Cavity inflation is closed, weight will be lifted slowly, when reaching requirement for height, stop inflation, after weight is dismantled, operate relief valve
Handle or foot pedal, objective table drops to original state again.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
Enclose and be defined, on the premise of design spirit of the present invention is not departed from, technical side of the those of ordinary skill in the art to the present invention
The various modifications and improvement that case is made, should all fall into the protection domain that claims of the present invention determines.
