Abstract
The invention discloses a novel inflatable shaft structure, which comprises a hollow main shaft body, an expansion airbag and expansion blocks, wherein the expansion airbag is arranged inside the hollow main shaft body, the hollow main shaft body is provided with a plurality of elongated holes, the expansion blocks are arranged inside the elongated holes, each expansion block comprises a hard end part and a soft bottom, the soft bottom is in an arc shape, and the outer surface of the hard end part is provided with a plurality of projections. Through the way, the novel inflatable shaft structure is simple in structure, the friction force between the expansion blocks and a winding drum is large, the phenomenon that the winding drum slips can be avoided, the expansion blocks are free from scratching the surface of the airbag, the service life of the airbag is prolonged, and simpleness and practicability can be realized.
Description
Technical field
The present invention relates to the air-expanding shaft technical field, particularly relate 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 the 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 the existing air-expanding shaft, expansion block can cause scratch to balloon surface.
Summary of the invention
The technical matters that the present invention mainly solves provides 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 present invention 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 hole on the described hollow spindle body, described expansion block is arranged in the 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 cooperates with described strip shape interporal lacuna.
In a preferred embodiment of the present invention, described hard end adopts solid rubber to make.
In a preferred embodiment of the present invention, described soft bottom adopts soft rubber to make.
In a preferred embodiment of the present invention, described hard end and soft bottom are bonded together by adhesives.
In a preferred embodiment of the present invention, described projection is conical shaped projections.
The invention has the beneficial effects as follows: the Novel air swelling shaft structure that the present invention discloses, the friction force between expansion block and the reel is large, the phenomenon that reel skids can not occur, and expansion block can not cause scratch to balloon surface, has prolonged the service life of air bag, and is simple and practical.
Description of drawings
Fig. 1 is the structural representation of Novel air swelling shaft structure of the present invention one preferred embodiment;
Fig. 2 be among Fig. 1 expansion block A-A to cutaway view;
The mark of each parts is as follows in the accompanying drawing: 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 invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1 and Fig. 2, the embodiment of the invention 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 hole on the described hollow spindle body 1, described expansion block 3 is arranged in the 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 cooperates 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 and soft bottom 32 are bonded together by adhesives.
The Novel air swelling shaft structure that the present invention discloses, the friction force between expansion block 3 and the reel is large, the phenomenon that reel skids can not occur, and expansion block 3 can not cause scratch to balloon surface, has prolonged the service life of air bag, and is simple and practical.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification sheets of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
