Preferably, two flat positions 212 parallel to each other are arranged on the side wall of the pin 21, and an arc surface 213 is arranged between the two flat positions 212, specifically, the two arc surfaces 213 are arranged oppositely. In other embodiments, only one flat 212 may be disposed on the outer wall of the pin 21.
As shown in fig. 7, in this embodiment, four bifurcate notches 1112 extending along the length direction of the sleeve 11 are disposed on the side wall of the tensioning portion 111, the bifurcate notches 1112 divide the tensioning portion 111 into four tensioning pieces 1113 capable of being elastically folded outwards, each tensioning piece 1113 is disposed near the insertion hole 13 side and is provided with the guide portion 1111, the guide portion 1111 is formed by inward protruding of the end of the tensioning piece 1113 away from the boss 12, specifically, the inner surface of the guide portion 1111 is curved, and the end of the pin shaft 21 away from the pin head 22 is also curved.
In this embodiment, the two flat positions 212 are both provided with the hooking holes 211, and preferably, the hooking holes 211 penetrate through the two flat positions 212 of the pin 21. The guide parts 1111 of two of the tension sheets 1113 on the sleeve 11 are buckled into the hooking hole 211, and the other two tension sheets 1113 are abutted against the cambered surface 213.
By adopting the assembly structure, the guide part 1111 can be clamped and matched with the hooking hole 211, the backstop performance between the rivet sleeve 1 and the rivet body 2 is improved, and the tensioning piece 1113 can be abutted against the cambered surface 213, so that the clamping effect of the rivet sleeve 1 on a plate is improved.
In this embodiment, a receiving groove 222 for the boss 12 to be inserted is formed on a side of the pin head 22 close to the pin shaft 21. Through set up in round pin head 22 and accomodate groove 222, make rivet cover 1 can hide in rivet body 2 below, both can avoid the foreign object to imbed between the joint gap of rivet cover 1 and rivet body 2, can avoid rivet cover 1 to expose again, promote whole aesthetic property.
Preferably, the inner side wall of the accommodating groove 222 gradually inclines toward the center of the accommodating groove 222 from the groove opening to the groove bottom wall, the circumferential side wall of the boss 12 is obliquely arranged and attached to the inner side wall of the accommodating groove 222, and specifically, the boss 12 is in a step shape. Through the setting of above-mentioned structure, increased the area of contact between boss 12 and the round pin head 22, made the lifting surface area increase of rivet cover 1 and rivet body 2, the atress distributes more evenly, has further improved the reliability that both connect.
In this embodiment, the hook 14 is disposed on the circumferential sidewall of the boss 12, and a deformation groove 121 for facilitating bending deformation of the hook 14 is disposed on the circumferential sidewall at the position of the hook 14, specifically, two deformation grooves 121 are symmetrically disposed on the boss 12.
The hooks 14 are arranged on the circumferential side wall of the boss 12, so that the distance between the two hooks 14 is maximized, the stability of the rivet body 2 when being connected with the rivet sleeve 1 is improved, and the pin head 22 and the boss 12 are not easy to swing mutually. In addition, the deformation groove 121 is formed in the boss 12, so that a deformation space is provided for the hook 14, the hook 14 is prevented from being difficult to deform due to the influence of the circumferential side wall of the boss 12 during bending deformation, and the assembly difficulty is reduced.
Preferably, the avoiding hole 221 is opened at a position on the pin head 22 opposite to the flat position 212, and correspondingly, the hook 14 corresponds to the flat position structure of the insertion hole 13, that is, the deformation groove 121 corresponds to the flat position structure of the insertion hole 13. Through the structure, the structure of the boss 12 is more uniform and reasonable, the size of the rivet can be effectively reduced, and the backstop performance of the rivet is ensured.
The invention further provides an antenna which comprises at least two stacked plates, and in this embodiment, the antenna further comprises the retaining rivet, wherein the plate is provided with a mounting hole through which the retaining rivet passes, and the retaining rivet passes through the mounting hole and clamps and fixes the plate by means of a boss 12 and a tensioning part 111.
