Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the gradual change inflatable docking facilities that inside contracts for space described in the utility model comprises docking pipeline, the first end (in figure right-hand member) of described docking pipeline is provided with butt flange 10, described docking pipeline comprises coaxial outer tube 7 and interior pipe 8, it is mezzanine space 9 between outer tube 7 and interior pipe 8, the first end (in figure right-hand member) of outer tube 7 and the first end (in figure right-hand member) of interior pipe 8 are all connected with butt flange 10 and butt flange 10 is provided with the annular through-hole (not shown) communicated with mezzanine space 9, close between second end (in figure left end) of outer tube 7 and second end (in figure left end) of interior pipe 8 and connect, the inwall of interior pipe 8 is provided with five groups of collar stops 1 successively to the direction of first end from the second end and spacing between five groups of collar stops 1 is more and more less, also can be increasing, often organize collar stop 1 to form near the collar stop 1 arranged by two, the elastic body of tubulose is separately installed with between two adjacent groups collar stop 1, comprise the first elastic body 2, second elastic body 3, 3rd elastic body 5 and the 4th elastic body 6, each elastomeric two ends are tightly connected with corresponding two groups of collar stops 1 respectively, each elastomeric termination to be placed between two collar stops 1 and to be sealed, first elastic body 2, second elastic body 3, 3rd elastic body 5 is identical with the elasticity of the 4th elastic body 6 or substantially identical, be positioned at head, the tube wall of the interior pipe 8 between tail two groups of collar stops 1 be provided with multiple in the through hole 4 that is interlinked to the outside, first elastic body 2, second elastic body 3, the length of the 3rd elastic body 5 and the 4th elastic body 6 reduces successively, each elastic body is followed successively by air-retaining liner, bearing layer and elastic layer from inside to outside, and air-retaining liner is butyl rubber film, and bearing layer is aramid fiber, and elastic layer is rubber film.
As Figure 1-Figure 5, during use, this docking facilities is connected on the control device by butt flange 10, and the docking mezzanine space 9 of pipeline is connected with the high-pressure air feed seal of tube of control convenience, do not inflate before docking, each elastic body invests the inwall of interior pipe 8, and its overall internal diameter is comparatively large, is easy to be inserted on the docking post of docking object and controlled device; After on the docking post interior pipe 8 being inserted in controlled device, start to inflate in mezzanine space 9, the air pressure of inflation is determined according to the external diameter of the docking post of controlled device, specific as follows:
As shown in Figure 2, when the external diameter of the docking post of controlled device is less, inner gas pressure is relatively large, because the length of the first elastic body 2 is the longest, so expansion is maximum after its inflation, the internal diameter of the air bag jointly formed with the inwall of interior pipe 8 after inflation is minimum, namely the central through hole diameter that surrounds of air bag is minimum, second elastic body 3, the internal diameter that 3rd elastic body 5 and the 4th elastic body 6 inflate the air bag that inwall that is rear and interior pipe 8 is formed jointly increases successively, namely the diameter of central through hole that each air bag surrounds increases successively, now the first elastic body 2 inflates the inwall of air bag and the wall contacts docking post of controlled device that are jointly formed with the inwall of interior pipe 8 afterwards.
As shown in Figure 3, when the external diameter of the docking post of controlled device is a bit greatly, inner gas pressure is a little bit smaller, first elastic body 2 and the second elastic body 3 inflate that rear expansion is comparatively large and internal diameter is basically identical, the internal diameter of the air bag that the 3rd elastic body 5 and the 4th elastic body 6 are formed jointly with the inwall of interior pipe 8 after inflating reduces successively, now the inwall of air bag that jointly formed with the inwall of interior pipe 8 after inflating of the first elastic body 2 and the second elastic body 3 all with the wall contacts docking post of controlled device.
As shown in Figure 4, the docking post of controlled device internal diameter larger some time, inner gas pressure is a little bit smaller again, first elastic body 2, second elastic body 3 and the 3rd elastic body 5 inflate that rear expansion is comparatively large and internal diameter is basically identical, the internal diameter of the air bag that the 4th elastic body 6 is formed jointly with the inwall of interior pipe 8 after inflating is minimum, now the inwall of air bag that jointly formed with the inwall of interior pipe 8 after inflating of the first elastic body 2, second elastic body 3 and the 3rd elastic body 5 all with the wall contacts docking post of controlled device.
As shown in Figure 5, when the external diameter of the docking post of controlled device is maximum, inner gas pressure is minimum, it is basically identical that first elastic body 2, second elastic body 3, the 3rd elastic body 5 and the 4th elastic body 6 inflate rear internal diameter, now the inwall of air bag that jointly formed with the inwall of interior pipe 8 after inflating of the first elastic body 2, second elastic body 3, the 3rd elastic body 5 and the 4th elastic body 6 all with the wall contacts docking post of controlled device.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
