Abstract
The utility model provides a pulley follow-up type self-locking device and an optical fiber sight glass. The pulley follow-up type self-locking device comprises a pulley, a cord and a circular arc lantern ring. The circular arc lantern ring is fixed on the pulley. The center of the circular arc lantern ring and the center of the pulley are overlapped. The circular arc lantern ring can rotate with rotation of the pulley. The outer edge of the circular arc lantern ring is larger than a groove of the pulley. The cord is wound on the pulley. The edges of the circular arc sleeve ring are connected with the cord. When the pulley slides, the cord does not separate from the pulley. The optical fiber sight glass is characterized in that a camera is installed at one end of the cord; and the camera connected with the cord can rotate in an all-round mode by rotating the cord and adjusting elasticity. The circular arc sleeve ring can rotate together with the pulley, so that loosening caused by idle running due to twisting of the cord can be avoided.
Description
Technical field
The utility model relates to a kind of self-locking structure and use the sight glass of this self-locking structure.
Background technology
Pulley is widely used in actual life.Aspect commercial production, can be used for the lift heavy large cargo, can be used for supporting and transmission power.Aspect medical, can be used as base apparatus part into medical facilities such as endoscopes.So research pulley in-use performance has important project meaning and learning value.To prolong pulley service life in order simulating, to strengthen the safety of operation performance, the experimental set-up design just becomes one of its key issue.
Present pulley gear mostly manufactures different size according to same principle, and the common ground of this device is very effectively to prevent to thread off phenomenon such as loosening.Its design-calculated key is whether can realize self-locking when rope is loosening.
Now, existing device can be realized simple anti-tripping phenomenon, generally is to be implemented on the simple device, the pulley that uses on for example large-scale crane, and the shortcoming of this device is that the anticreep buckle is to fix, implement device self-locking when pulley rotates again.As OGD used in the medical treatment, need rotary pulley to adjust direction to reach the rotation camera function.And price is also relatively more expensive, is unfavorable for promoting, and is only applicable on the large-scale plant.
Summary of the invention
The purpose of this utility model is to provide to overcome and occurs a kind of pulley trailing type self-locking structure device and the optical fiber sight glass that rope takes off shortcomings such as mouth becomes flexible when using.
The purpose of this utility model is achieved in that
A kind of pulley trailing type of the utility model self-locking structure device, it is characterized in that: comprise pulley, rope, the circular arc collar, the circular arc collar is fixed on the pulley, the center of the circular arc collar overlaps with the center of pulley, the circular arc collar can rotate with the rotation of pulley, and the outer of the circular arc collar is greater than the groove of pulley, and rope is on pulley, the edge and the rope of the circular arc collar join, and rope did not break away from pulley when pulley slided.
A kind of optical fiber sight glass of the utility model adopts a kind of pulley trailing type self-locking structure device of the present utility model, and it is characterized in that: an end of rope is equipped with camera, makes the omnibearing rotation of its bonded assembly camera by the degree of tightness of rotating rope.
Advantage of the present utility model is:
(1) advantage of the present utility model is that pulley has slideable self-locking structure.When using pulley, its self-locking device can improve the safety performance of pulley, prevents to thread off.Simultaneously of the present utility model simple in structure, easy for installation, adopted at present the manufacture craft of technology maturation, price advantage is obvious.
(2) the utility model servo-actuated self-locking device can conveniently move along with the rotation of pulley.When pulley no longer was fixing the use, as OGD used in the medical treatment, or the underwater exploration camera lens needed rotary pulley to adjust direction to reach the rotation camera function.The circular arc collar can rotate together along with pulley, just can avoid rope owing to reverse the idle running that causes, what cause is loosening.
Description of drawings
Fig. 1 is the structural representation of a kind of pulley trailing type of the utility model self-locking structure device;
Fig. 2 is the structural representation of a kind of optical fiber sight glass of the utility model.
The specific embodiment
For example the utility model is done description in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1, a kind of pulley trailing type self-locking structure device comprises pulley 1, rope 2, and the circular arc collar 3 of outside.Fix a circular arc collar 3 on pulley 1, its center overlaps with pulley center, can rotate with the rotation of pulley 1, and owing to the groove of its outer greater than pulley, its edge and rope 2 join, and guarantee can not break away from pulley 1 at pulley 1 slip rope 2.When needs swing or rotating pulley 1, the outer circular arc collar 3 of pulley can rotate along with the rotation of pulley 1, promptly with movable pulley.
When a section of rope is hanging weight, pulley 1 rotates, and rope 2 moves along groove, because the radius of the circular arc collar 3 is greater than pulley 1, the collar 3 edges are near pulley 1 edge, rope 2 moves from its gap, can not thread off loosening phenomenon when pulley 1 clickwise, pulley 1 right side rope tension owing to rope 2 appears in position relation, the left side line relaxation, the circular arc collar 3 clockwise rotates with pulley, is tightly pressing the easily loosening rope 2 in left side, during opposite spin in like manner.
In conjunction with Fig. 2, a kind of optical fiber sight glass need make its bonded assembly camera 4 omnibearing rotations carry out shooting work by the degree of tightness of rotary pulley 1 both sides rope 2.Camera 4 is to tension one side's rope 2 directions rotation, and at this moment another side rope 2 is very easily threaded off.When operator's rotary pulley 1, the circular arc collar 3 can rotate with pulley 1, and then, the still large-area pulley groove that covered is realized self-locking action, the safe handling pulley.
Claims (2)
1. pulley trailing type self-locking structure device, it is characterized in that: comprise pulley, rope, the circular arc collar, the circular arc collar is fixed on the pulley, the center of the circular arc collar overlaps with the center of pulley, the circular arc collar can rotate with the rotation of pulley, and the outer of the circular arc collar is greater than the groove of pulley, and rope is on pulley, the edge and the rope of the circular arc collar join, and rope did not break away from pulley when pulley slided.
2. optical fiber sight glass adopts the described a kind of pulley trailing type self-locking structure device of claim 1, and it is characterized in that: an end of rope is equipped with camera, makes the omnibearing rotation of its bonded assembly camera by the degree of tightness of rotating rope.
