Abstract
The utility model discloses a high-strength rivet, belonging to fasteners. The utility model aims at providing a high-strength rivet. The high-strength rivet comprises a rivet sleeve pipe main body provided with a rivet head and a core rod main body arranged in the rivet sleeve pipe main body and provided with a rod head, wherein an internal thread is arranged in the rivet sleeve pipe main body (2), and the other end of the rivet sleeve pipe main body is provided with a guide cone (5); the core rod main body (6) is arranged in the rivet sleeve pipe main body (2) through an external thread; and a pressing sleeve sleeved on the core rod main body (6) is arranged between the rivet sleeve pipe main body (2) and the rod head (4). In the utility model, the core rod main body of the original polished shaft structure is changed into a screw rod with a facture ring slot, so that when the core rod main body is fractured along the fracture ring slot, and the rest part of the core rod main body is left in the rivet sleeve pipe main body so as to enhance and reinforce the rivet sleeve pipe main body; and the shear strength of the rivet sleeve pipe main body is enhanced, and the riveting reliability and the service life are increased.
Description
Technical field
The utility model relates to a kind of fastening piece, relates in particular to a kind of pulling rivet.
Background technique
As everyone knows, pulling rivet is self-plugging rivet mostly at present; Usually be made up of rivet sleeve body, the core bar body that is inserted in this rivet sleeve body, this rivet must be extracted the core bar body out after accomplishing from the rivet sleeve body.Because rivet sleeve body tube wall is thinner, easy deformation and produce looseningly not only under the strong vibration situation, and lower, the easy fracture of shearing strength can not be satisfied the requirement of high-strength structure spare riveted joint.
Summary of the invention
In order to overcome the defective that exists in the existing technology, the utility model aims to provide the high tenacity rivet of a kind of shearing strength height, long service life, good reliability.
To achieve these goals, the utility model adopts following technological scheme: it comprises that an end is provided with the rivet sleeve body of rivet head, is located at the core bar body that an end in this rivet sleeve body has the bar head; Be provided with internal thread in the rivet sleeve body, the other end of this rivet sleeve body is provided with the guiding tapering; The core bar body is provided with breaks annular groove, is provided with outside thread breaking between annular groove and the bar head at this on the core bar body; Between rivet sleeve body and bar head, the gland that is enclosed within on the core bar body is arranged.
The top of rivet head is provided with cross recess; The other end of core bar body is the square toes structure.
Compare with existing technology; The utility model is owing to adopted technique scheme; On the basis of the common pulling rivet of loosing core, the core bar body of original optical axis structure changed into and had the screw rod of breaking annular groove; Therefore after the fracture of annular groove place was broken on core bar body edge, the remainder of core bar body was then stayed in the rivet sleeve body it is carried out the intensity reinforcing; Not only overcome the rivet sleeve body because of the defective of the thin easy deformation of tube wall but also strengthened the shearing strength of rivet sleeve body, improved riveted joint reliability and working life.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the left view of Fig. 1.
Among the figure: rivet head 1 rivet sleeve body 2 glands 3 bar heads 4 guiding taperings 5 core bar bodies 6 are broken annular groove 7 square toes structures 8 cross recesses 9
Embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described further:
In Fig. 1～2: rivet sleeve body 2 one ends are provided with the rivet head 1 that guides tapering 5, the other end to be provided with bulb-type, and the inwall of this rivet sleeve body is provided with internal thread; The core bar body 6 that at one end has bar head 4 is provided with breaks annular groove 7, and this core bar body is arranged in the rivet sleeve body 2 through the outside thread that is located at bar head 4 and break between the annular groove 7; The gland 3 that is enclosed within on the core bar body 6 is arranged between rivet sleeve body 2 and bar head 4.
For the ease of staking, rivet sleeve body 2 rotates thereupon when avoiding turning core bar body 6, is provided with cross recess 9 at the top of rivet head 1.For the ease of turning core bar body 6, the square toes structure 8 of being convenient to clamping is arranged in the other end milling of this core bar body.
During use, rivet sleeve body 2, gland 3 and core bar body 6 are assembled according to shown in Figure 1, turned core bar body 6 then and can gland 3 be enclosed within on the rivet sleeve body 2 and form with it interference fit gradually through bar head 4; After rivet clasp was accomplished, core bar body 6 was along breaking the fracture of annular groove 7 places, remainder then stay in the rivet sleeve body 2 to and this rivet sleeve body forms and reinforces.
Claims (3)
1. high tenacity rivet comprises that an end is provided with the rivet sleeve body of rivet head, is located at the core bar body that an end in this rivet sleeve body has the bar head; It is characterized in that: the inwall of rivet sleeve body (2) is provided with internal thread, and the other end of this rivet sleeve body is provided with guiding tapering (5); Core bar body (6) is provided with breaks annular groove (7), breaks between annular groove and the bar head (4) and is provided with outside thread being positioned at this on the core bar body (6); The gland (3) that is enclosed within on the core bar body (6) is arranged between rivet sleeve body (2) and bar head (4).
