Description
Technical field
The utility model belongs to tubulose type component interconnection technique field, particularly relates to a kind of expansion connecting device.
Background technique
The component of tubulose class are connected through two pipelines by screw or bolt when connecting, and easily damage tubular structure.When different two the tubulose type components of diameter connect, one end less for diameter can be extend in the larger one end of diameter, then realize connecting through two pipes fastening by fastening piece vertical axial, easily damage component.When the component diameter of two tubulose classes is identical, connection is more inconvenient, and cannot reuse after tubulose class part is impaired, cost is high, also reduces the working life of component.
Model utility content
The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of expansion connecting device, and for solve in prior art, the attended operation of tubulose class part is inconvenient, easy damaged component, working life short, high in cost of production problem.
For achieving the above object and other relevant objects, the utility model provides a kind of expansion connecting device, comprise two panels, the outer wall of described panel is arc surface, and the internal face of described panel is burnishing surface, when the burnishing surface of two panels is fitted, two panels form the expansion piece of profile cylindrical structure, the outer wall of described panel is provided with projection, and one of them panel is provided with the mounting hole radially across this panel, is provided with the ejection piece promoting another block panel movement in described mounting hole.
The beneficial effects of the utility model are: structure is simple, connection is convenient, stretch in workpiece tube by panel, and withstand one piece of panel by ejection piece, two pieces of panels are made separately to form tension force, realize the connection of workpiece tube, avoid defective work piece pipe, improve the working life of workpiece tube, reduce cost.
Further, described mounting hole is arranged on projection place, and through panel and projection.
Further, described projection is arc-shaped structure, and when the burnishing surface of two panels is fitted, two projections form cylindrical structures.
Adopt the beneficial effect of above-mentioned further scheme to be: to make panel obtain spacing in axial motion direction by projection, connect location and installation convenient.
Further, described mounting hole is tapped hole, and described ejection piece is screw rod.
Further, described mounting hole is tapped hole, and described ejection piece is bolt.
Adopt the beneficial effect of above-mentioned further scheme to be: to adopt tapped hole, screw in ejection piece during operation and just can promote panel and move, simple to operation, cost is low.

Embodiment
By particular specific embodiment, mode of execution of the present utility model is described below, person skilled in the art scholar the content disclosed by this specification can understand other advantages of the present utility model and effect easily.
Notice, structure, ratio, size etc. that this specification institute accompanying drawings illustrates, content all only in order to coordinate specification to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, still all should drop on technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, quote in this specification as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the utility model.
As depicted in figs. 1 and 2, expansion connecting device of the present utility model, comprises two panels 2, the outer wall of panel 2 is arc surface 22, the internal face of panel 2 is burnishing surface 21, and when the burnishing surface 21 of two panels 2 is fitted, two panels 2 form the expansion piece of profile cylindrical structure.The two ends of expansion piece extend in two workpiece tube 1 respectively, and the diameter at expansion piece two ends can be identical, also can be different, arrange according to whether the internal diameter size of two workpiece tube 1 is identical.When the internal diameter size of two workpiece tube 1 is identical, the external diameter of the cylinder at expansion piece two ends is identical, when the internal diameter of two workpiece tube 1 varies in size, the minor diameter fit of the external diameter of the cylinder at expansion piece two ends and two workpiece tube 1 is arranged, so that when promoting panel 2, the arc surface 22 of panel 2 is fitted with the internal face of workpiece tube 1, increases lifting surface area, improves the stability be fitted and connected.
As depicted in figs. 1 and 2, the outer wall of panel 2 is provided with projection 3, projection 3 is arc-shaped structure, when the burnishing surface 21 of two panels 2 is fitted, two projections 3 form cylindrical structure, propped up the end of two workpiece tube 1 by projection 3, avoid panel 2 to move around in the axial direction, improve the stability of installing.One of them panel 2 is provided with the mounting hole 4 radially across this panel 2, is provided with the ejection piece 6 promoting another block panel 2 movement in mounting hole 4.Mounting hole 4 is arranged on projection 3 place, and through panel 2 and projection 3, mounting hole 4, through the projection 3 on same panel 2 and this panel, is convenient to ejection piece 6 and is withstood another block panel 2 through mounting hole 4, makes two pieces of panels 2 separately produce the internal face of tension force top tight workpiece pipe 1.Wherein, mounting hole 4 can adopt tapped hole, and ejection piece 6 is screw rod or bolt, and employing is threaded into promotion ejection piece 6 and drives panel 2 to withstand the internal face of workpiece tube 1, and simple to operation, cost is low.
The utility model, by simple anatomical connectivity, realizes the connection of workpiece tube 1, simple to operation, avoids the damage of workpiece tube 1 simultaneously, repetitive cycling can use, improves the working life of workpiece tube, reduce costs.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or changes.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
