Abstract
The utility model discloses a novel inflatable shaft structure which comprises a hollow spindle body, an expansion air bag and expansion blocks, wherein the expansion air bag is arranged in the hollow spindle body; a plurality of strip-shaped holes are formed in the hollow spindle body; the expansion blocks are arranged in the strip-shaped holes, and comprise hard end parts and soft bottoms; the soft bottoms are arc; and a plurality of bumps are arranged on the external surfaces of the hard end parts. With the adoption of the mode, the novel inflatable shaft structure is simple and practical; friction forces among the expansion blocks and a winding drum are great; the winding drum cannot slip; the expansion blocks cannot scratch the surface of the air bag; and the service life of the air bag is prolonged.
Description
Technical field
The utility model relates to the air-expanding shaft technical field, particularly relates to a kind of Novel air swelling shaft structure.
Background technology
Air-expanding shaft all is used in many enterprises in modern times.Air-expanding shaft is a kind of special rolling, unreeling shaft, namely passes through the axle that high-pressure aerated rear surface (referring to expansion block) can projection, and axle that venting rear surface part (referring to expansion block) is retracted rapidly is called air-expanding shaft.Airpressure axle, main axis of dilatation, flatulence axle, inflatable roller, inflation axle, pressure axis, inflatable roller etc. are again in its title variation.In existing air-expanding shaft, because the friction force of key bar and reel inwall is inadequate, the phenomenon that reel skids can appear; In addition, in existing air-expanding shaft, expansion block can cause scratch to balloon surface.
The utility model content
The technical matters that the utility model mainly solves is to provide a kind of Novel air swelling shaft structure, can solve problems of the prior art, the phenomenon that reel skids can not occur, and can not cause scratch to balloon surface.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of Novel air swelling shaft structure is provided, comprise: hollow spindle body, swelling gasbag and expansion block, it is inner that described swelling gasbag is arranged on described hollow spindle body, offer a plurality of strip shapes holes on described hollow spindle body, described expansion block is arranged in described strip shape hole, described expansion block comprises hard end and soft bottom, described soft bottom is circular arc, described hard end outer surface is provided with a plurality of projections, and described hard end coordinates with described strip shape interporal lacuna.
In preferred embodiment of the utility model, described hard end employing solid rubber is made.
In preferred embodiment of the utility model, described soft bottom adopts soft rubber to make.
In preferred embodiment of the utility model, described hard end and soft bottom are bonded together by adhesives.
In preferred embodiment of the utility model, described projection is conical shaped projections.
The beneficial effects of the utility model are: the Novel air swelling shaft structure that the utility model discloses, friction force between expansion block and reel is large, the phenomenon that reel skids can not occur, and expansion block can not cause scratch to balloon surface, extended the service life of air bag, simple and practical.
Description of drawings
Fig. 1 is the structural representation of the utility model Novel air swelling shaft structure one preferred embodiment;
Fig. 2 be in Fig. 1 expansion block A-A to cutaway view;
In accompanying drawing, the mark of each parts is as follows: 1, hollow spindle body, 2, swelling gasbag, 3, expansion block, 31, the hard end, 32, soft bottom, 33, projection.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made more explicit defining.
See also Fig. 1 and Fig. 2, the utility model embodiment comprises:
A kind of Novel air swelling shaft structure, comprise: hollow spindle body 1, swelling gasbag 2 and expansion block 3, described swelling gasbag 2 is arranged on described hollow spindle body 1 inside, offer a plurality of strip shapes holes on described hollow spindle body 1, described expansion block 3 is arranged in described strip shape hole, described expansion block 3 comprises hard end 31 and soft bottom 32, and described soft bottom 32 is circular arc, and described hard end 31 outside faces are provided with a plurality of projections 33.
Described soft bottom 32 is circular arc, contacts with the outside face of swelling gasbag 2, can not cause the scratch to swelling gasbag 2.
Described hard end 31 outside faces are provided with a plurality of projections 33, and described projection 33 is conical shaped projections, and is large to the pressure of reel inwall, is not prone to and skids.
Described hard end 31 coordinates with described strip shape interporal lacuna, and expansion block 3 is firmly withstood the reel inwall under the impetus of swelling gasbag 2, and the band movable reel rotates.
Described hard end 31 adopts solid rubber to make.
Described soft bottom 32 adopts soft rubber to make.
Described hard end 31 is bonded together by adhesives with soft bottom 32.
The Novel air swelling shaft structure that the utility model discloses, the friction force between expansion block 3 and reel is large, the phenomenon that reel skids can not occur, and expansion block 3 can not cause scratch to balloon surface, has extended the service life of air bag, and is simple and practical.
The above is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification sheets and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
