Abstract
A novel air shaft comprises a rubber airbag, a drum and an expanding block component. The rubber airbag is disposed in the middle of the drum, and the expanding block component is arranged between the rubber airbag and the drum. The expanding block component comprises a swallow-tail guide rail which is provided with backlash springs, swallow-tail raised keys and tower springs, wherein the backlash springs are disposed below the swallow-tail raised keys, and the tower springs are disposed above the swallow-tail raised keys. The technical problems that a rubber airbag in the existing structure is uneven in size of partial expansion after being inflated and is prone to fatigue, breakdown and air leakage are solved.
Description
Technical field
The utility model relates to a kind of for the new-type air-expanding shaft in the retractable volume mechanism of packing, plastics, weaving, papermaking, printing machinery class.
Background technology
At present general air-expanding shaft, the most frequently used expansion block assembly is protruding key reed-type, in use often occurs:
(1) reed is easy to disconnected the backwardness and punctures rubber gas capsule, i.e. gas leakage can't work.
(2) protruding key is local contact in the outer garden of rubber gas capsule, and without the swollen meeting increase of splashing of the position of protruding key, rubber gas capsule fills repeatedly, exitting is easy to fatigue fracture and namely leaks gas after the rubber gas capsule inflation.
The utility model content
The utility model has overcome existing air-expanding shaft reed and has had no progeny easily and puncture rubber gas capsule, protruding key unbalance stress and cause that rubber gas is wrapped up in and hold fatigable defective.A kind of new-type air-expanding shaft has comprised rubber gas capsule 4, expansion block assembly, cylindrical shell 7, (seeing Fig. 1, Fig. 2, Fig. 3).Wherein rubber gas capsule 4 comprises that an end stops up, the spindle nose of other end band induction opening, it is arranged on the centre of cylindrical shell 7, the expansion block assembly comprises that back lash spring 5, pagoda spring 3, the dovetail slideway 2 below the protruding key 1 of dovetail form, protruding key forms, be provided with successively back lash spring 5, the protruding key 1 of dovetail form, pagoda spring 3 on the described dovetail slideway 2, wherein said back lash spring 5 is arranged at the protruding key of described dovetail form 1 below, and described pagoda spring 3 is arranged at the protruding key of described dovetail form 1 top.The expansion block assembly is arranged between rubber gas capsule and the cylindrical shell 7, the protruding key 1 of its dovetail form is arranged in each elongated slot of cylindrical shell 7, end at cylindrical shell is provided with the valve 6 of inflating for rubber gas capsule 1, rubber gas capsule 1 is splashed swollen during by valve 6 inflation, the protruding key 1 of the dovetail form of expansion block assembly stretches out outside the elongated slot of cylindrical shell 7, i.e. the object of expansion sleeve on air-expanding shaft.

Fig. 2 is the section-drawing of main cutaway view A-A
Fig. 3 is the section-drawing of main cutaway view B-B
The specific embodiment
A kind of new-type air-expanding shaft, (seeing Fig. 1, Fig. 2, Fig. 3) selects pagoda spring 3 to be the resilience of expansion block assembly, and pagoda spring 3 is one or several, dovetail slideway 2, protruding key 1 structure of dovetail form, stable working, elasticity stable, spring is not easily broken to fall.Two expansion block assembly to the end in the setting of cylindrical shell 7 inwalls, be circular arc because dovetail slideway 2 is inside and outside, the expansion block assembly wraps on rubber gas capsule 4 cylindricals, it is evenly swollen to splash after rubber gas capsule 4 inflations, in the same size increases the service life, solved after the existing structure rubber gas capsule inflation part little inequality that swells of splashing, easily fatigue fracture gas leakage.Because of gapped between the protruding key 1 of dovetail form and the dovetail slideway 2, sound is arranged during work, the spy arranges back lash spring 5 below protruding key, and back lash spring 5 is one or several, Noiseless environment friendly after the swelling.
