The rivet is a rod structure component, and the rivet rod is sequentially provided with a tail tooth, a breaking groove, an annular groove, a polish rod and a rivet cap.
The split type structure is used, the original lantern ring is divided into a plurality of parts, the parts comprise the cap head and at least one sleeve, so that the processing difficulty is reduced, different materials can be used for different sleeves, and different requirements of various regions are met.
The existing fastener product has the advantages that the lantern ring is integrally machined, different deformation bulging, riveting, shearing resistance and other functions are required to be realized in different areas of the sleeve on the integrated lantern ring, the design and production process difficulty is high, and the cost is high.
The fastener of the invention has the advantages that: compared with the existing integral lantern ring, the design of the cap head and the split sleeve is innovatively used. Different fastening and connecting requirements are realized by using a plurality of sleeves which are combined in sequence. Due to the limitations of processing technology, cost and the like, the riveting thickness of the original single-sided rivet product is limited, but the riveting thickness can be increased infinitely theoretically by adopting the situation of combining a plurality of sleeves. Meanwhile, the sleeves in different areas of the fastener are correspondingly processed according to actual design requirements so as to improve the performance of the single-sided rivet product, the respective design and processing are more efficient and convenient, the cost is lower, and the design and processing difficulty is reduced.

Detailed Description
The present invention is further described below in conjunction with the following detailed description, which is intended to further illustrate the principles of the invention and is not intended to limit the invention in any way, but is equivalent or analogous to the present invention without departing from its scope.
With reference to the attached drawings.
As shown in the figure, the split type single-side riveting fastener comprises a rivet 1 and a lantern ring, wherein the lantern ring is formed by combining a cap head 2 and a sleeve 3 which are of a split combined structure and the rivet 1;
the cap head 2 is a hollow cylindrical ring structure component and is provided with a deformation area 21 which is used for being embedded and fastened with the ring groove 13 of the rivet 1 after being extruded and deformed, and a groove 22 of a ring structure which is arranged on the inner wall of one end of the cylindrical ring;
the sleeve 3 is a hollow cylindrical structure component, and has an inner diameter in interference fit with the polish rod 14 of the rivet 1, and one end of the cylindrical structure is provided with a matching end 31 which is embedded and matched with the groove 22 of the circular ring structure of the cap head 2.
As shown in fig. 6 and 7, fig. 6 is a split blind rivet fastener with two casing pipes 3 combined; FIG. 7 is a schematic view of another three-section sleeve 3 combined split blind rivet fastener.
The sleeve 3 of the invention can be formed by combining a plurality of sections of independent pipes which are made of different performance materials and are sequentially arranged along the polish rod 13 of the rivet 1. In the multi-section independent tube combination structure, the end part of the section combined with the cap head 2 is provided with a matching end 31 which is matched and combined with the groove 22 of the circular ring structure of the cap head 2 in an embedding way.
The sleeve 3 according to the invention can also be composed of at least one section of individual tube made of the same material, arranged in succession along the polish rod 14 of the rivet 1. In the multi-joint independent tube combination, the end of the joint combined with the cap head 2 is provided with a matching end 31 which is matched and combined with the groove 22 of the circular ring structure of the cap head 2 in an embedding way.
The rivet 1 is a rod structure component, and the rivet rod is sequentially provided with a tail tooth 11, a snapping groove 12, a ring groove 13, a polish rod 14 and a rivet cap 15.
The method for installing the combined rivet comprises the following steps:
(1) firstly, the cap head 2, the rivet 1 and the sleeve 3 are assembled by using an assembling tool, and the end of the matching end 31 at the front end of the sleeve 3 is embedded, matched and fixed with the groove 22 at one end of the cap head 2 to form an integral fastener combination, as shown in fig. 1. If a multi-joint sleeve 3 structure is required, as shown in fig. 6 and 7, different sleeves 3 can be sleeved in combination according to fastening connection requirements during assembly, and the installation sequence and direction of the sleeves 3 with the matching ends 31 need to be paid attention.
