Abstract
The utility model discloses a kind of reinforced jump ring, it bends to a semiround body do not closed by a steel band, described semiround body comprises a line part and a camber line portion, in one end of semiround body, line part is connected with camber line portion, and its joint forms an outside arc convex, at the other end of semiround body, form an opening between line part and camber line portion, the width of this opening is less than the maximum normal distance of camber line portion inner side surface to line part inner side surface.The jump ring of this structure, camber line portion plays a part fastening, line part then coupled columns is filled in capable spacing, and linear structure is not easy to occur distortion, forms an opening between line part and camber line portion, so just be beneficial to installation, and the width of opening is less than the maximum normal distance of camber line portion inner side surface to line part inner side surface, just can ensure that jump ring can not come off, joint forms an outside arc convex, the elastic force of joint can be strengthened, make whole jump ring more be difficult to distortion.
Description
Technical field
The utility model relates to a kind of fastening piece, especially a kind of jump ring.
Background technique
Plunger pump generally includes plunger, piston spring, spring seat, jump ring, plunger bushing, and piston spring is used for by plunger often toward external pressure, and jump ring is then used for plunger spacing.In the prior art, it is spacing that some employing pin coupled columns fill in row, the jump ring coupled columns of some employing circles is filled in capable spacing, because the rigidity of piston spring is large, in the long movement process repeatedly of plunger, the problems such as these jump rings easily deform, dislocation, will cause the plunger of high-speed motion to fly out from plunger bushing like this, cause mechanical disorder even security incident.
Model utility content
The technical problem to be solved in the present invention is to provide a kind of not yielding jump ring with dislocating.
For solving the problems of the technologies described above, technological scheme of the present invention is: a kind of reinforced jump ring, it bends to a semiround body do not closed by a steel band, described semiround body comprises a line part and a camber line portion, and in one end of semiround body, line part is connected with camber line portion, its joint forms an outside arc convex, at the other end of semiround body, form an opening between line part and camber line portion, the width of this opening is less than the maximum normal distance of camber line portion inner side surface to line part inner side surface.
The jump ring of this structure, camber line portion plays a part fastening, line part then coupled columns is filled in capable spacing, and linear structure is not easy to occur distortion, forms an opening between line part and camber line portion, so just be beneficial to installation, and the width of opening is less than the maximum normal distance of camber line portion inner side surface to line part inner side surface, just can ensure that jump ring can not come off, joint forms an outside arc convex, the elastic force of joint can be strengthened, make whole jump ring more be difficult to distortion.
Further, the opening end of described line part is provided with outside flange; The angle of described flange and line part line stretcher is acute angle.
Preferably, the steel band that described jump ring adopts is 65Mn spring steel, and its thickness is 0.6 millimeter, and wide is 2.8 millimeters, and the total length after expansion is 36.99 millimeters; The maximum normal distance of described semiround body camber line portion's outer side surface and line part outer side surface is 12 ± 0.15 millimeters, and the length of described flange is 1.5 millimeters; A/F between line part and camber line portion is 9 millimeters.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, preferred embodiment of the present utility model is:
A kind of reinforced jump ring, it is by one thick 0.6 millimeter, the 65Mn steel band of wide 2.8 millimeters bends to a semiround body do not closed, described semiround body comprises a line part 1 and a camber line portion 2, in one end of semiround body, line part 1 is connected with camber line portion 2, its joint forms an outside arc convex 3, at the other end of semiround body, the opening that a width is 9 millimeters is formed between line part 1 and camber line portion 2, camber line portion 2 inner side surface is 12 ± 0.15 millimeters to the maximum normal distance of line part 1 inner side surface, the opening end of described line part 1 is outwards provided with the flange 4 that length is 1.5 millimeters, described flange 4 is 15 degree with the angle of line part 1 line stretcher, total length after whole jump ring launches is 36.99 millimeters.
