Fig. 3 is the structural side view of the utility model.

Label in figure is as follows:

1. shaft, 11. recessed portions, 2. connectors, 21. interconnecting pieces, 22. ends, 23. internal screw threads.

Specific embodiment

Middle embodiment is described further utility model with reference to the accompanying drawing.

Roller shaft is symmetrical structure, and in order to facilitate observation of, Fig. 1 to Fig. 3 only gives the part-structure of roller shaft.Such as Fig. 2 With a kind of New roller axis shown in Fig. 3, including shaft 1, shaft 1 is hollow tube, and 1 inside both ends of shaft are equipped with connector 2, even Junctor 2 is equipped with internal screw thread 23, and shaft 1 includes recessed portion 11, and recessed portion 11 is squeezed towards 2 side of connector and connector 2 to be connected It connects.

The drum shaft replaces traditional roller shaft using hollow tube, and light weight is at low cost.Connector 2 is combined with shaft 1, is led to Cross the fixed positioning for realizing shaft 1 to connector 2, when use only needs to intercept the shaft 1 of required length, then group loads onto connector 2, therefore producer can store a certain number of connectors 2, eliminate the manufacturing procedure complicated to shaft 1, improve life Produce efficiency and flexibility.It is press-connected between connector 2 and shaft 1,1 both ends link position of shaft can be processed simultaneously, added Work speed is fast, and the axial direction and circumferential strength of junction are high, can guarantee the axially position of structure rotational stabilization and shaft 1. 2 axial dimension of connector is small, squeezes out two grooves to shaft 1 by external force and is attached, and required space is few, easy to operate, Secondary operation can be carried out to the product not reached requirement.

As shown in Fig. 2, single corresponding four recessed portions 11 of connector 2, axisymmetrical of four recessed portions 11 about shaft 1 Setting.Recessed portion 11 is arranged close to two-by-two, has bulge-structure between two be arranged close to recessed portion 11, is carried out to shaft 1 In pressure process, the material on shaft 1 at recessed portion 11, which is extruded between recessed portion 11, forms protrusion.Fig. 2 is the first reality The structure sectional view of example is applied, therefore only shows a recessed portion 11.When processing, first connector 2 is inserted into shaft 1, it is right After shaft 1 is positioned, available hydraulic device pushes four pressure heads to squeeze shaft 1, forms concave part and the company of extruding on 1 shell of shaft Junctor 2, to realize the connection of the two.The line of two concave parts of 1 side of shaft intersects with the axis of shaft 1, can reduce Torque in 1 rotary course of shaft.

Connector 2 includes interconnecting piece 21 and end 22, and interconnecting piece 21 is located at 1 inside of shaft, end 22 and 1 end face phase of shaft It supports.End 22 and interconnecting piece 21 constitute step structure, and end 22 offsets with 1 end face of shaft, reduce 1 medial surface of shaft with connect The axial force on 21 surface of portion, improves the stability of structure.22 outer surface of end is flushed with 1 outer surface of shaft, connector 2 Outer surface with shaft 1 is cylindroid.In the first embodiment, internal screw thread 23 runs through connector 2.In second of embodiment, Connector 2 is closed at one end, the other end is equipped with internal screw thread 23.

Described above is only the explanation to utility model, so that those of ordinary skill in the art's can completely implements we Case, but be not the limitation to utility model, those skilled in the art are can according to need after reading this specification to this Embodiment makes the modification of not creative contribution, these are all without creative modification, but as long as in utility model All by the protection of Patent Law in scope of the claims.
