Abstract
The utility model relates to a steel ball bolt. The utility model is composed of a bolt shaft, a steel ball, a spring and a sleeve barrel. The upper end of the sleeve barrel is provided with a through hole. The diameter of the through hole is smaller than the diameter of the steel ball. The steel ball and the spring are arranged in the sleeve barrel from the bottom of the sleeve barrel. The bottom of the sleeve barrel is provided with convex edges which are inwards punched. The sleeve barrel is embedded in a positioning groove which is arranged on the tail end of the shaft rod. The utility model has the advantages of convenient assembly, and stable performance comparison.
Description
The utility model is specifically related to a kind of Steel ball bolt.
The application of Steel ball bolt is very extensive, as handle of box spanner etc.Its structure is made up of axostylus axostyle, steel ball and spring.The production method of prior art is: the steel ball of spring is packed in the locating slot of axostylus axostyle end, then in the inside convex edge of the edge of locating slot punching press one, so that steel ball and spring are fixed in the guide slot, and steel ball can hold at the elastic force of spring down, the part spheroid is arranged a little more than locating slot, play positioning action whereby.The disadvantage of this latch is a unstable properties.Its reason: the one, the punching press degree during the punching press convex edge is difficult for holding, and kick the beam or the overweight serviceability that all can have influence on latch, thereby production efficiency is not high; The 2nd, when the processing locating slot, cause more required aperture, aperture for big owing to tending to carry a little iron filings secretly on the drill bit, this makes the punching press degree be difficult for more holding again.
The purpose of this utility model provides a kind ofly to be convenient to assemble and Steel ball bolt that performance is more stable.
The purpose of this utility model realizes by following technological means: a kind of Steel ball bolt, form by axostylus axostyle, steel ball, spring and sleeve.It is characterized in that: there is a perforation sleeve upper end, and the diameter of perforation is slightly less than the diameter of steel ball, and steel ball and spring be from the cover tube bottom sleeve of packing into, the convex edge of punching press in the cover tube bottom is oriented, and sleeve is embedded in the locating slot of axostylus axostyle end.
The utility model can also be made a kind of pair of Steel ball bolt, is about to sleeve and makes two ends perforation is all arranged, and there is the shape of mesopore at the middle part, and two steel balls are respectively from the mesopore sleeve two ends of packing into, and spring is also from pack into sleeve and between two steel balls of mesopore.This sleeve embeds in the locating hole of axostylus axostyle, a kind of pair of steel ball fastening screw.
The utility model has the advantages that: the first, production and assembly are easy, thereby help enhancing productivity; The second, the performance of product is more stable, is difficult for producing fault.
Below in conjunction with accompanying drawing structure of the present utility model is elaborated.
Fig. 1 is a three-dimensional exploded view of the present utility model;
Fig. 2 is a combination generalized section of the present utility model;
Fig. 3 is the generalized section of another embodiment of the present utility model;
Fig. 4 is the combination generalized section of another embodiment of the utility model;
Among the figure:
2. axostylus axostyle 3. steel balls 4. springs 5. sleeves 21. locating slots 22. locating holes
51. sleeve outer diameter 52. perforation 53. convex edges, 54. mesopores, 55. perforation
As shown in Figure 1, the utility model is made up of axostylus axostyle 2, steel ball 3, spring 4 and sleeve 5.The entire outer diameter 51 of sleeve 5 closely cooperates with circular locating slot 21 internal diameters of axostylus axostyle 2, there is perforation 52 its upper end, the diameter of perforation 52 is slightly less than the diameter of steel ball 3, with steel ball 3 and spring 4 sleeve 5 of packing into from sleeve 5 bottoms, then in inside punching press convex edge, sleeve 5 bottoms 53, steel ball 3 and spring 4 are fixed in the sleeve 5, at last with in the locating slot 21 of sleeve 5 embedding axostylus axostyles 2 ends (as shown in Figure 2).
As shown in Figure 3, the sleeve 5 of the utility model can also be made two ends all has perforation 55, middle part that the shape of mesopore 54 is arranged, two steel balls 3 are respectively from pack into the two ends of sleeve 5 of mesopore 54, spring 4 is also from pack into sleeve 5 and between two steel balls 3 of mesopore 54, then sleeve 5 is embedded in the locating hole 22 of axostylus axostyles 2 ends, a pair of Steel ball bolt.
Because sleeve 5 of the present utility model is after assembling in advance, embed again in locating slot 21 on the axostylus axostyle 2 or the locating hole 22, therefore both can guarantee that the performance of latch was more stable, a large amount of production of can going ahead of the rest again enhanced productivity.
Structure of the present utility model is proved to be, and a kind of simple and convenient assembly can be provided, and the Steel ball bolt that performance is more stable can reach the purpose of this utility model fully.
