Abstract

The utility model provides a pulley of a stable structure. The pulley of the stable structure comprises a pulley body and a pulley shaft arranged in the pulley body, wherein the pulley shaft comprises an inner shaft and an outer shaft connected with the inner shaft in a sleeved mode. The pulley of the stable structure has the advantages of being stable in structure, long in service life, reasonable in design, simple in structure, easy and convenient to manufacture, convenient to install and the like.

Description

Constitutionally stable pulley
Technical field
The utility model relates to mechanical engineering technical field, is specifically related to constitutionally stable pulley.
Background technique
Pulley is that a periphery has groove, the steamboat that can sway, in mechanics, typical pulley is can be around the circle wheel of central shaft rotation, circumferential surface at the circle wheel has groove, rope is wound in to groove, arbitrary end at rope for traction two ends firmly, the frictional force between rope and circle wheel can impel the circle wheel to rotate around central shaft, whether move the position by the central shaft of pulley, pulley can be divided into by " static pulley ", " movable pulley ", the central shaft of " static pulley " maintains static, the central shaft of " movable pulley " can move, the major function of pulley is the tractive load, change application of force direction, through-put power etc., existing static pulley is along with the prolongation of service time, wheel shaft and pulley main body easily slide mutually, the operator is required great effort more.
Summary of the invention
Technical problem to be solved in the utility model is to provide constitutionally stable pulley, reasonable in design, simple in structure, manufacture easy, structural stability, can avoid pulley inner loosening along with the prolongation of service time, can extend the working life of pulley, simultaneously, can make the installation of pulley more convenient.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: constitutionally stable pulley, and comprise pulley main body, be located at the wheel shaft in pulley main body, described wheel shaft comprises interior axle, is socketed in the outer shaft on interior axle.
As preferably, the length of described interior axle is greater than the length of outer shaft, makes outer shaft can all be included in pulley main body inside, increases the area of contact of pulley main body and wheel shaft, increasing friction force, thus make the structure of pulley more stable.
As preferably, the two ends of described interior axle are connected with the notch of outward opening, make rope or coupling shaft can pierce into like a cork pulley, thereby make the installation of pulley more convenient.
As preferably, be socketed with the resistance ring on described outer shaft, thereby further increased the area of contact of pulley main body and wheel shaft, increased frictional force, make the structure of pulley more stable.
Beneficial effect:
The constitutionally stable pulley that the utility model adopts technique scheme to provide, reasonable in design, simple in structure, manufacture easy, structural stability, can avoid pulley inner loosening along with the prolongation of service time, can extend the working life of pulley, simultaneously, can make the installation of pulley more convenient.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, pulley main body 1, wheel shaft 2, interior axle 21, outer shaft 22, notch 3, resistance ring 4.
Embodiment
As shown in Figure 1, constitutionally stable pulley, comprise pulley main body 1, be located at the wheel shaft 2 in pulley main body 1, described wheel shaft 2 comprises interior axle 21, is socketed in the outer shaft 22 on interior axle 21, the length of described interior axle 21 is greater than the length of outer shaft 22, the two ends of described interior axle 21 are connected with the notch 3 of outward opening, on described outer shaft 22, are socketed with resistance ring 4.
The interior axle 21 of wheel shaft 2 has increased the area of contact of pulley main body 1 with wheel shaft 2 with the socket design of outer shaft 22, has increased frictional force, thereby has made the structure of pulley more stable, and the design of resistance ring 4 has further increased the area of contact of pulley main body 1 with wheel shaft 2.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has more been used the terms such as pulley main body 1, wheel shaft 2, interior axle 21, outer shaft 22, notch 3, resistance ring 4, do not get rid of the possibility of using other term.Using these terms is only in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
