Expandable pulley

Technical Field

The utility model relates to a pulley field particularly, relates to an expandable pulley.

Background

The pulley is a small wheel with a groove on the periphery and capable of rotating around a shaft. A simple machine consisting of a grooved disc rotatable about a central axis and a flexible cable (rope, tape, cable, chain, etc.) running over the disc, which can rotate about the central axis, is called a pulley.

Current pulley is mostly single fixed structure, and pulley self is fixed can not expand with being connected of carrier self, and this kind of structure loses the variety of pulley self when guaranteeing stability, makes the shock attenuation effect of whole device relatively poor simultaneously.

In view of this, the present inventors have invented an expandable pulley.

Preferably, the upper end parts of the first fixing frame and the second fixing frame are both provided with unthreaded holes, and the insides of the unthreaded holes are in threaded connection with fixing bolts.

Preferably, a fixing rod penetrates through the side walls of the first fixing frame and the second fixing frame, and the fixing rod is fixedly connected with the first fixing frame and the second fixing frame.

Preferably, the base, the limiting plate and the roller can be vertically angularly switched.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) the prior fixed structure is converted into a variable structure, so that the device has better activity, can better adapt to the terrain by depending on the activity of the device when moving to a bumpy road section, and simultaneously reduces fluctuation;

(2) whole device adopts two-layer mount to fix it, and then makes whole structure's stability higher, and the structure is compacter.
