Description

Novel prevent linking of rope that wanders away piece

Technical Field

The utility model relates to a chain link especially relates to a novel prevent chain link of wandering away rope.

Background

The traditional anti-lost rope connecting piece is made of metal materials, and after the male piece and the female piece are connected and formed, the male piece and the female piece are extruded together with strong force, so that the female piece can expand, and two problems can be caused during use, namely unsmooth rotation, friction and abnormal sound are caused; secondly, the strength of the tensile force is not good enough.

In order to overcome the technical defects, the inventor previously developed a similar product, which includes a rotating male element, a rotating female element and a cover element, wherein the connection between the rotating male element and the rotating female element is realized by interference fit between the cover element and a notch groove on the rotating female element, and the structure may cause the cover element to easily fall off after being used for a period of time, so as to separate the rotating male element from the rotating female element.

Therefore, it is an urgent need to solve the problem of the art to develop a novel anti-wandering string link which is tightly connected and is not easily separated from components.

SUMMERY OF THE UTILITY MODEL

The utility model provides a solve above-mentioned not enough, provide a novel prevent linking piece of wandering away rope.

The above object of the present invention is achieved by the following technical solutions: a novel chain element of a lost rope comprises a sleeve element, a fixing element and a rotating element, wherein one end of the fixing element is provided with a T-shaped notch groove, the other end of the fixing element is provided with a fixing hole, one end of the rotating element is provided with a T-shaped chuck matched with the T-shaped notch groove, and the other end of the rotating element is provided with a rope connecting hole;

the T-shaped chuck comprises an end head and a rotating shaft, the end head is in a round cake shape, and the T-shaped notch groove comprises an end head groove and a rotating shaft groove which are respectively matched with the end head and the rotating shaft;

the sleeve part is provided with a containing groove, the side wall of the containing groove is provided with a pin shaft hole, the rotating part is clamped and plugged into the containing groove together after the fixing part, the rope connecting hole is positioned outside the telescopic containing groove, the fixing hole is communicated with the pin shaft hole, and the fixing part and the sleeve part are fixedly connected through a pin shaft, a rivet or a screw component.

Furthermore, the diameter of the end head groove of the T-shaped notch groove is 1-3mm larger than that of the end head of the T-shaped clamping head, and the diameter of the rotating shaft groove is 1-3mm larger than that of the rotating shaft.

Further, the sleeve member, the fixed member and the rotating member are all made of plastic.

Compared with the prior art, the utility model the advantage be: the rotating link element of the anti-lost rope of the utility model can not generate abnormal sound in the rotating process, and the rotation is smooth; the cooperation of T shape structure makes it bear the intensity of tension and promotes greatly, simultaneously, in the use, removes sleeve part or round pin axle damage, and the condition that the separation can not appear in fixed part and rotating member otherwise, and firm in connection is stable.
