Abstract
A hollow rivet comprises a rod portion and a sleeve. The sleeve is provided with a through hole, the through hole have two sections of different inner diameters, and lengthwise cracks are formed in the large-inner-diameter end of the sleeve; a conical head portion is arranged at one end of the rod portion and a threaded portion is arranged at the other end of the rod portion; threads are arranged in the middle of the rod portion and an annular groove is formed between the threads and the threaded portion. The hollow rivet has the advantages of being reliable in connection, convenient to operate and the like.
Description
Technical field
The present invention relates to a kind of mechanical fastening system, in particular to a kind of tubular-shank rivet.
Background technique
Rivet of the prior art, one section, general rivet has larger diameter termination, for fixture, blocks, the other end has relatively little diameter, through fixture, with hammer, impacts, make this end diameter become large, can block by fixture, by the fixing fixture of such mode.
China Patent Publication No. CN1447033A, disclose a kind of tubular-shank rivet connected that guarantees reliably.This tubular-shank rivet comprises: the rivet body of the hollow consisted of axial region and an end boss; And length is greater than the axle of the rivet body length of inserting this rivet body hollow hole.Have price low, connect the advantages such as reliable.But, exist to use inconvenient, the shortcoming such as application area is narrow.
For problems of the prior art, the utility model has been done further improvement to tubular-shank rivet of the prior art, make tubular-shank rivet simple in structure, connect reliable and with low cost.
The model utility content
The utility model provides a kind of tubular-shank rivet, have easy to operate, connect the advantages such as reliable.
A kind of tubular-shank rivet, comprise bar section and sleeve, and sleeve has through hole, and described through hole comprises two sections different internal diameters, and large diameter one end of sleeve has longitudinal crack; Bar section one end has conical nose, and the other end has screw section; The centre of described bar section has screw thread, between screw thread and screw section, has annular groove.
As further preferred, the number of described crackle is 4.
As further preferred, the external diameter of screw section is less than the minimum diameter of sleeve.
As further preferred, the external diameter of the screw thread in the middle of bar section is greater than the minimum diameter of sleeve.
As further preferred, the screw thread in the middle of bar section is fine thread, and described screw section is T shape screw thread.
Beneficial effect: easy to use, connect reliable and low cost and other advantages.
The accompanying drawing explanation
Fig. 1 is the original state figure of tubular-shank rivet;
Fig. 2 is the phase diagram after screwing of tubular-shank rivet.
Embodiment
As shown in Figure 1, Fig. 1 is the initial installation diagram of tubular-shank rivet.Tubular-shank rivet comprises bar section and sleeve 6.Sleeve 6 centers have through hole, through hole has two sections different internal diameters, the bossed annulus of excircle tool of sleeve 6, internal diameter near the projection annular direction is smaller with respect to another section internal diameter, that is to say, be less than the diameter of internal diameter of another sector hole of sleeve 6 along the diameter of the endoporus internal diameter of projection annular direction.Sleeve 6 away from the projection annulus an end, there is longitudinal crack on the circumference of sleeve, under the effect of extruding, sleeve 6 these ends are curling separately along crackle.As a kind of preferred, the number of crackle is 4.
Bar section has a conical nose 2, and the diameter of conical nose 2 is much larger than the diameter footpath of sleeve 6.The neutral position of bar section has screw thread 3, and the external diameter of screw thread 3 is greater than the small diameter inner hole of sleeve 6.Position near screw thread 3 has annular groove 4, and when being subject to external force when excessive, bar section can be in the fracture of the position of annular groove 4, and the other end of bar section has screw section 5, and the external diameter of screw section 5 is less than the minimum diameter of sleeve 6.
While using tubular-shank rivet connected element 1, rubber buffer 8 is inserted in sleeve 6, abuts against on the projection annulus of excircle of sleeve 6, sleeve 6 is inserted in the hole of parts 1, makes rubber pad 8 between parts 1 and projection annulus.Insert from the large diameter end of sleeve the screw section 5 of bar section, the screw section 5 of bar section passes sleeve 6, use nut 7 to coordinate with screw section 5, as shown in Figure 2, rotating nut 7, bar section is moved to nut 7 directions, the large diameter end of conical nose 2 clamp sleeves 6, because there is crackle in this end, under the pressuring action of conical nose 2, the large diameter end check of sleeve 2 is opened, sleeve 2 is outwardly-bent under the extruding of conical nose 2, after bar section moves certain displacement, screw thread rotation in the middle of bar section is cut into the little internal diameter section of sleeve 6, when annular groove 4 moves out sleeve 6, can stop screwing of screw thread 7 according to actual conditions.By applying external force, annular groove 4 places in bar section, make the fracture of bar section.Complete the process of the whole fixed component 1 of tubular-shank rivet.
This embodiment just embodies the preferred special case of the utility model spirit, and those skilled in the art fully can be according to the purport of the utility model patent, and flexible, reached best implementation result in addition.The utility model is modified or is equal to replacement, and do not break away from the spirit and scope of the utility model patent, it all should be encompassed in the middle of the claim scope of the utility model patent.
Claims (5)
