Abstract
The utility model relates to a swivel hook which is composed of a hook body, a connecting body and a swiveling ring. The utility model is characterized in that the head part of the connecting body is a circular arc shape, a long slot is arranged in the connecting body, a through hole is arranged at the connecting body and is perpendicular to the long slot, external threads are arranged at the bottom part of the connecting body, the through hole is arranged on the hook body and is assembled with the connecting body, the swiveling ring is sheathed on the connecting body by nuts, and the swiveling ring can do the plane swiveling action of 360 DEG; thus, a wire rope can not be kinked even if an operating worker swivels or moves aloft; thereby, the service life of the wire rope is raised.
Description
The utility model relates to the swivel hook on the falling protector.
During operation, the most frequently used falling protector is a speed difference autocontrol human body falling protector to the workman, is the self-locking device that hanging safety strap (rope) is climbed aloft, and they have a common characteristic is all must be connected with safety strap by the usefulness hook, sees shown in Figure 3.The lower end of hook 1 is provided with a manhole 11, one annular slab, 3 hanging sleeves are in through hole 11, and be crossed on annular slab 3 on steel rope 2 tie mutually be fixed on the cover 4 in, and another termination of steel rope 2 places in the falling protector, and can as required steel rope 2 be pulled out, in addition be with gum cover 5 in that cover 4 is outer, in case scuffing people during operation.The subject matter that this structure exists is that steel rope rotates with the rotation of hook, and aloft during operation, it is frequent that human body rotates, moves, and makes steel rope produce in various degree kink, has influenced work efficiency and tension intensity.Rope service-life is reduced.
The purpose of this utility model is: provide a kind of and can freely rotate 360 °, and can avoid the swivel hook of steel rope kink effectively.
The purpose of this utility model is achieved in that a swivel hook is made up of coupler body, connector, swivel becket, it is characterized in that: the head of connector is circular-arc, establish an elongated slot in it, the position vertical with elongated slot is provided with a through hole, the bottom of connector is provided with outside thread, coupler body is provided with the through hole that combines with connector, and swivel becket is nested with on connector by nut.
The utility model has the advantages that: 180 ° rotation before and after coupler body can be done in connector, swivel becket can be done 360 ° plane rotation on connector, the personnel of operation can arbitrarily rotate and move so aloft, can not make the kink of safety strap or steel rope, so improved the service life of safety strap or steel rope.
Concrete structure of the present utility model further specifies by following examples and accompanying drawing thereof:
Fig. 1: be the utility model constructional drawing;
Fig. 2: be the utility model connector figure;
Fig. 3: be prior art structure side view.
Referring to Fig. 1-2: a swivel hook is made up of coupler body 1, connector 2, swivel becket 3, it is characterized in that: the head of connector 2 is circular-arc, establish an elongated slot 21 in it, the position vertical with elongated slot 21 is provided with a through hole 22, the bottom of connector 2 is provided with outside thread 23, coupler body 1 is provided with the through hole 11 that combines with connector 2, and swivel becket 3 is nested with on connector 2 by nut 4.During assembling, the bottom of coupler body 1 is plugged in the elongated slot 21 of connector 2, and the through hole 22 that the through hole 11 on it is aimed on the connector 2, pass above-mentioned through hole 22 with a pin 5,11, with coupler body 1, connector 2 rivetings knot together, and coupler body 1 can pin 5 be the rotation that axle is done 180 ° of front and back, swivel becket 3 is nested with middle part at connector 2 by nut 4, and can connector 2 be that axle is done 360 ° plane rotation, nut 4 screws on the outside thread 23 of connector 2, and the distance between scalable swivel becket 3 and the connector 2, (not shown) is tied mutually with the steel rope in the falling protector in the bottom of swivel becket 3.No matter the people during operation, is to rotate, move aloft like this, all can not make the steel rope kink, so improved the service life of steel rope, operating personal is felt safe, reliably.
