Description
Technical Field
The utility model relates to a rope technical field especially relates to a wire rope is from locking-type fastener.
Background
The steel wire rope fastener is also called a steel wire rope clip, is mainly used for temporary connection of a steel wire rope or fixation of the steel wire rope after the steel wire rope is threaded through a connecting ring, and is a steel wire rope clamp which is widely applied in hoisting operation, load sharing of a cantilever scaffold and wind rope catching of a material hoist.
The steel wire rope clip that uses most often is striding on horse formula U type buckle, but because the single intensity of this buckle is not high, so in practical application, the fixed of a position just need install a plurality of buckles, simultaneously because single buckle has two screws, installs complicacy and easily causes stress concentration, has the damage to wire rope.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a wire rope is from locking-type fastener, improves wire rope's joint strength, reduces stress damage.
In order to achieve the above purpose, the technical solution of the present invention is as follows:
a steel wire rope self-locking fastener comprises a hollow shell sleeve with openings at two ends, a rotating shaft is arranged in the shell sleeve, an oval locking wheel is fixed on the rotating shaft, and an installation channel is formed between two sides of the locking wheel perpendicular to the rotating shaft and the inner wall of the shell sleeve.
Further, the locking wheel is a gear.
Furthermore, one end of the rotating shaft penetrates through the shell sleeve and is fixed with a handle.
The utility model has the advantages that:
1. the elliptical locking wheel is used as a locking structure, so that the structure is simple and reliable, the friction force is uniformly distributed, and the steel wire rope is not easy to damage;
2. the self-locking steel wire rope is safe and reliable as the steel wire rope is more and more tensioned;
3. the shell sleeve with a semi-closed structure is adopted, so that the internal structure can be used for a long time and is not easy to damage;
4. the operation is simple and easy to learn, the parts are not easy to lose due to the integrated structure, and the popularization and application values are wide.

The device comprises a shell 1, a rotating shaft 2, a locking wheel 3, an installation channel 4, a steel wire rope 5 and a handle 6.
Detailed Description
The present invention will be described in further detail with reference to examples.
The utility model provides a wire rope is from locking-type fastener, including both ends opening and hollow shell 1, two open ends of shell 1 are convenient for wire rope 5 penetrate and wear out, are equipped with two pivots 2 along wire rope 5's the direction of penetrating in proper order in the shell 1, all are fixed with oval-shaped locking wheel 3 in two pivots 2, form installation passageway 4 between 3 perpendicular to pivot 2's of locking wheel both sides and the 1 inner wall of shell, clearance fit between 3 both sides that are on a parallel with pivot 2 of locking wheel and the 1 inner wall of shell.
The use of this fastener is shown in figures 1 to 4:
the method comprises the following steps: as shown in fig. 1, at this time, the elliptical locking wheel 3 in the shell 1 is in a vertical state, the calibers of the two installation channels 4 are larger than the diameter of the steel wire rope 5, the steel wire rope 5 penetrates through the lower end of the installation channel 4 on the left side, penetrates out of the upper end of the installation channel, bypasses the tie-down point after penetrating out of the installation channel, and then penetrates into the installation channel 4 on the right side, as shown in fig. 2, the locking wheel is a schematic diagram of the state when the steel wire rope 5 penetrates;
step two: as shown in fig. 3, the locking wheel 3 in a vertical state is deflected, and after deflection, the caliber of the installation channel 4 is smaller than the diameter of the steel wire rope 5, that is, the periphery of the locking wheel 3 presses against the steel wire ropes 5 on both sides;
step three: as shown in fig. 4, when the wire rope 5 is pulled down, the locking wheel 3 in the deflected state further deflects due to the action of friction force, so that the force of the locking wheel 3 pressing against the wire rope 5 is increased, and finally, the locking effect is achieved, and the effect of tightening the wire rope is achieved.
Because wire rope 5 in the installation passageway 4 is by the roof pressure when, the active surface between wire rope 5 and the shell 1 inner wall is great, for riding on horse formula U type buckle of prior art, can reduce the stress that wire rope 5 received by a wide margin, difficult damage wire rope 5.
In order to facilitate the deflection of the locking wheel 3, one end of the rotating shaft 2 in the embodiment penetrates through the shell 1 and is fixed with a handle 6.
To increase the friction between the locking pulley 3 and the wire rope 5, the locking pulley 3 of the present embodiment is a gear.
The above-mentioned embodiments are merely illustrative of the inventive concept and are not intended to limit the scope of the invention, which is defined by the claims and the insubstantial modifications of the inventive concept can be made without departing from the scope of the invention.
