Abstract
The invention discloses anti-lost rope pulleys, belong to mechanical equipment technical field.The central axis being respectively erected in including both ends on the pulley bracket that two are parallel to each other, several rotatable pulleys are evenly arranged on the central axis, the wheel pressing shaft parallel with central axis is also set up on the pulley bracket, it it is provided with several on the wheel pressing shaft prevents drawstring from falling off, rotatable pinch roller, the pinch roller is arranged in a one-to-one correspondence with pulley.Drawstring is pressed in the groove of pulley by the way that pinch roller is arranged in the side of pulley, solves the problems, such as that drawstring falls off from pulley, increase the safety that pulley uses by the present invention.
Description
Technical field
The present invention relates to a kind of anti-lost rope pulleys, belong to mechanical equipment technical field.
Background technique
Pulley is that can have groove around the circle wheel of center axis rotation in the periphery of circle wheel, drawstring is wound in recessed
Slot firmly pulls the either end at drawstring both ends, then the frictional force between drawstring and circle wheel can promote circle to take turns around center axis rotation,
Whether moved by the position of pulley center axis, pulley is divided into fixed pulley and movable pulley, and the central axis of fixed pulley is fixed, moves and slides
The central axis of wheel can move, and pulley is mainly used for changing the direction of power, and movable pulley is mainly used for changing the size of power, and will determine
Pulley and running block, which are fitted together, may make up pulley blocks, and pulley blocks are not only laborsaving but also can change the direction of power;Pulley and
Pulley blocks are used widely in machinery, electromechanics, engineering construction, recreation ground etc., under normal circumstances, the stress of drawstring on pulley
The orthogonality of center shaft in direction and pulley, when the drawstring Impact direction and pulley that are mounted in pulley or pulley blocks central axis not
When orthogonal, stress is larger or discontinuity, easily falls off out of groove, cause safety accident.
Summary of the invention
The anti-lost rope pulley that the object of the present invention is to provide a kind of structures simply, drawstring can be effectively prevent to fall off.
To achieve the above object, the technical scheme adopted by the invention is that:
Anti-lost rope pulley, the central axis being respectively erected in including both ends on the pulley bracket that two are parallel to each other, it is described in
It is evenly arranged with several rotatable pulleys in mandrel, also sets up the wheel pressing shaft parallel with central axis on the pulley bracket,
It it is provided with several on the wheel pressing shaft prevents drawstring from falling off, rotatable pinch roller, the pinch roller is arranged in a one-to-one correspondence with pulley.
A further improvement of the present invention is that: it is provided on the excircle of the pulley and pinch roller and accommodates the recessed of drawstring
Slot, the groove diameter of the pinch roller are greater than the diameter of drawstring.
A further improvement of the present invention is that: the outer diameter of the pinch roller is less than the outer diameter of pulley.
A further improvement of the present invention is that: the pulley is installed on center shaft by bearing.
By adopting the above-described technical solution, the technological progress achieved by the present invention is:
The present invention by the side of pulley be arranged pinch roller, drawstring is pressed in the groove of pulley, solve drawstring from
The problem of falling off on pulley increases the safety that pulley uses.
Detailed description of the invention
Fig. 1 is schematic perspective view of the invention.
Wherein: 1, pulley bracket 2, wheel pressing shaft 3, pinch roller 4, pulley 5, central axis.
The present invention is described in further details with reference to the accompanying drawings and examples:
Anti-lost rope pulley is set up on two pulley brackets 1 as shown in Figure 1, including two pulley brackets 1 being parallel to each other
Central axis 5 is evenly arranged with several rotatable pulleys 4 on central axis 5, and pulley 4 is mounted on central axis 5 by bearing;
The wheel pressing shaft 2 parallel with central axis 5 is also set up on pulley bracket 1, several rotatable pinch rollers 3 are provided on wheel pressing shaft 2, is pressed
Wheel 3 is arranged in a one-to-one correspondence with pulley 4, and the outer diameter of pinch roller 3 is less than the outer diameter of pulley 4.
The groove for accommodating drawstring is provided on the excircle of pulley 4 and pinch roller 3, the groove diameter of pinch roller 3 is greater than drawstring
Diameter, drawstring is pressed in the groove on the excircle of pulley 4 by pinch roller 3, can be effectively prevented drawstring from the recessed of pulley 4
It falls off in slot.
