The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Below in conjunction with other accompanying drawings the suspender component part is explained one by one.
Accompanying drawing 3 is the transparent view of support sleeve; Be divided into two parts up and down by the cylindrical tube inside that can clearly find out support sleeve among this figure; The upper tube internal diameter is provided with negative thread less than the internal diameter of lower tube on support sleeve body inwall, form support sleeve upper tube negative thread 3 and support sleeve lower tube negative thread 4.
Accompanying drawing 4 is the cutting ferrule block diagram, by finding out that cutting ferrule 8 is made up of cutting ferrule cylindrical tube 9, cutting ferrule exit skirt 10 among the figure, is provided with outside thread at an end of cutting ferrule cylindrical tube 9.
Accompanying drawing 6 is the block diagram of claw, and by finding out that claw 11 comprises that one has the steel plate 12 of cambered surface, on the cambered surface of steel plate, is provided with the hinged ear 13 vertical with the steel plate straight flange among the figure, hinged ear 13 is provided with pin hole 14.
Specify each component part below and how to be assembled into one.
The pin jointed end that two claw 11 subtends are closed up pull bar is clipped between the two hinged ears 13, and pivot pin 15 passes pin hole 14 and the hinge hole 7 of pull bar pin jointed end on the two hinged ears, realizes the hinged of two claws 11 and pull bar 6.
Through above-mentioned steps suspender is assembled, rotate cutting ferrule 8 this moment, and cutting ferrule 8 is moved to the support sleeve direction; Cutting ferrule exit skirt 10 breaks away from the hinged ear 13 of two claws; This moment, two claws 11 can serve as that axle carries out free opening and closing with pivot pin 15, and when cutting ferrule 8 is rotated to the claw direction, the hinged ear 13 of two claws gets into cutting ferrule exit skirt 10 inside; Because the hinged ear 13 of claw receives the restriction of cutting ferrule exit skirt 10, two claws 11 are in closure state and can not open at this moment.
When making; Can control the hinged ear 13 of claw for guaranteeing cutting ferrule exit skirt 10; Cutting ferrule exit skirt 10 cooperates extremely important with the size of the hinged ear of claw, the pin jointed end of two hinged ears and pull bar can draw within the cutting ferrule exit skirt and be as the criterion after its size cooperation was closed up with two claw subtends.
After making two claw closures, can round steel be picked up, claw two cambered surface steel plates 12 subtends are closed up the formed cambered surface in back should be greater than semicircle.
The concrete use step of this suspender is:
1, the earrings bolt with this suspender hangs on the suspension hook;
2, left-hand revolution cutting ferrule, on the cutting ferrule upward movement, cutting ferrule exit skirt and the hinged ear of two claws the plane contact disengagement, two claws can be opened freely;
3, this suspender is placed the axle centre, under the effect of gravity, two claws open automatically axle are stuck in the centre;
4, clickwise cutting ferrule, cutting ferrule moves downward, and the cutting ferrule exit skirt is pushed down plane on the hinged ear of two claws, and two claws can not be opened;
5, lifting winches to assigned position with round steel;
6, left-hand revolution cutting ferrule, on the cutting ferrule upward movement, cutting ferrule exit skirt and the hinged ear of two claws the plane contact disengagement, two claws can be opened freely, shift out from axle;
7, hanging axis finishes, the next work of beginning.
When guaranteeing that this suspender uses; Earrings bolt, pull bar and support sleeve carry out mortise; Like Fig. 1, shown in Figure 2, on the tube wall of support sleeve top, radially be provided with two stop screw holes 5, when the suspender assembled; Two stop screws are screwed into by this stop screw hole 5, prevent that earrings bolt and pull bar and support sleeve from relatively rotating.
When guaranteeing that this suspender uses, pivot pin does not come off, and is as shown in Figure 7, and pivot pin 15 1 ends are provided with annular boss 16, and the other end radially is provided with stop hole 17, when the suspender assembled, in pivot pin stop hole 17, inserts stop pin and gets final product.
