Abstract
The utility model belongs to the technical field of mechanical devices, in particular to a cantilever shaft locking mechanism, which comprises a shaft and a mounting hole for containing the shaft, and is characterized in that a limit shoulder is arranged in the middle portion of the shaft; a mounting end of the shaft is inserted into the mounting hole; the edge of the mounting hole is clamped by the limit shoulder; a radial half-cutting notch is arranged at the mounting end of the shaft; the shaft is divided into a shaft body and an elastic body by the half-cutting notch; axial screw holes are arranged on the shaft body and the elastic body; and the elastic body and the shaft body are connected through lock screws. The cantilever shaft locking mechanism has simple and ingenious structure and brief appearance, realizes self-locking function by self-deforming of the shaft, saves cost, and has high space use ratio and extremely high practical value.
Description
Technical field
The utility model belongs to mechanical equipment technical field, especially relates to a kind of cantilever shaft locking mechanism.
Background technique
At present, axle is installed in general employing mounting type shown in Figure 1 on the wallboard: offer a mounting hole on wallboard, the mounting end of axle inserts in the mounting hole, and axle is provided with flange plate, and flange plate and wallboard on the axle fix by screw.Though firmly degree is pretty good for such mounting type, needs to be provided with flange plate on the axle, not only can cause space availability ratio low, and waste material, and then has increased the cost of equipment, cause the waste of resource, increased the burden of enterprise.Simultaneously, the efficient of installation is lower, and labor intensity is bigger, when needing repairing, dismantles very inconveniently, has further increased entreprise cost, incompatible present development situation.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple and ingenious structure is provided, and outward appearance is brief, saves cost and the high cantilever shaft locking mechanism of space availability ratio.
The technological scheme that provides according to the utility model, described cantilever shaft locking mechanism comprises axle and is used for the mounting hole of ccontaining axle, it is characterized in that, the middle part of axle is provided with spacing shoulder, and the mounting end of axle inserts in the mounting hole, and the limited shoulder decometer is lived the mounting hole limit, the mounting end of axle offers hemisection notch radially, axle is divided into a body and elastomer two-part by the hemisection notch, offers axial screw hole on axle body and the elastomer, and elastomer links to each other by lock screw with the axle body.
As further improvement of the utility model, the part that is positioned at mounting hole on the described axle also offers seal groove, suit seal ring in the seal groove.
The utility model compared with prior art, advantage is: simple and ingenious structure, outward appearance is brief, the function of utilizing the deformation of axle self to carry out oneself's locking is saved cost and space availability ratio height, has very high use value.
