Abstract
The utility model discloses a kind of 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, 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, linear structure is not easy to occur distortion, an opening is formed 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 ensures that jump ring can not come off.
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, the technical solution of the utility model is: a kind of 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, 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, linear structure is not easy to occur distortion, an opening is formed 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 ensures that jump ring can not come off.
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.This flange conveniently can carry out dismounting to jump ring.
Preferably, the steel band that described jump ring adopts is 65Mn spring steel, and its thickness is 0.6 millimeter, and wide is 5 millimeters, and the length ratio in line part and camber line portion is 14: 21.4; 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 10 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 jump ring, it is by one thick 0.6 millimeter, the 65Mn steel band of wide 5 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, at the other end of semiround body, the opening that a width is 10 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 3 that length is 1.5 millimeters, described flange 3 is 15 degree with the angle of line part 1 line stretcher, total length after whole jump ring launches is 35.4 millimeters, the length ratio in line part 1 and camber line portion 2 is 14: 21.4.
