Description

Technical Field

[0001] The utility model relates to the technical field of rivets, and more specifically, to a ring groove rivet. Background Art

[0002] Ring groove rivets are a type of fastener manufactured using the Hooke principle. Their main feature is that they "never loosen". They are currently widely used in various fastening fields such as vehicles, ships, aviation, construction engineering, mechanical steel structures, bridges, containers, etc.

[0003] Ring groove rivets need to be fixed by riveting with a rivet gun during use. When riveting, the rivet cap is pressed onto the outside of the rivet by pressure. However, with the increase of usage time or the influence of improper operation, it will be found that the rivet cap rotates on the rivet, which causes the riveting position to gradually loosen. Utility Model Content

[0004] The main purpose of the utility model is to provide a ring groove rivet, aiming to solve the loosening problem caused by the rotation of the rivet cap on the rivet in the prior art.

[0005] In order to solve the above technical problems, a ring groove rivet is proposed, comprising: a rivet post, provided with an abutment portion and a locking portion, the locking portion and the abutment portion being coaxially arranged, the abutment portion having a diameter larger than the locking portion, the locking portion being provided with a plurality of first annular grooves, the first annular grooves being arranged obliquely relative to the locking portion;

[0006] A rivet cap is sleeved on the locking portion and is used to be clamped on the first annular groove when deformed under pressure.

[0007] In any of the above technical solutions, further, each of the first annular grooves is evenly arranged.

[0008] In any of the above technical solutions, further, the locking portion is provided with at least two second annular grooves, which are coaxially arranged compared to the locking portion, and one of the second annular grooves is connected to one of the first annular grooves close to the abutting portion, and another of the second annular grooves is connected to another of the first annular grooves away from the abutting portion.

[0009] In any of the above technical solutions, further, a third annular groove is provided at the connection between the abutting portion and the locking portion, and a convex ring is provided on the side of the third annular groove close to the locking portion, the diameter of the convex ring is larger than the diameter of the locking portion, and the diameter of the convex ring is smaller than the diameter of the abutting portion.

[0010] In any of the above technical solutions, further, the locking portion is provided with a plurality of convex stripes, the convex stripes are placed between the convex ring and the second annular groove, and the convex stripes are evenly arranged around the circumference.

[0011] In any of the above technical solutions, further, the convex stripes extend in a direction parallel to the axial direction of the locking portion.

[0012] In any of the above technical solutions, further, it also includes: a breaking portion, which is arranged on the side of the locking portion away from the abutting portion, the breaking portion and the locking portion are coaxially arranged, and a fourth annular groove is provided between the breaking portion and the locking portion.

[0013] In any of the above technical solutions, further, the diameter of the breaking portion is smaller than the diameter of the locking portion, and friction lines are provided on the outer side of the breaking portion.

[0014] The beneficial effects are:

[0015] The annular groove rivet of the present invention abuts against the fixed object through the abutting portion and cooperates with the rivet cap through the locking portion to achieve riveted fixation. At the same time, a plurality of first annular grooves are provided on the locking portion, and the first annular grooves are inclined relative to the locking portion. When the rivet cap is pressed onto the locking portion, the rivet cap is deformed and engaged with the first annular grooves. Moreover, due to the inclined setting of the first annular grooves, the rivet cap will not rotate, thereby avoiding the problem of loosening caused by the rotation of the rivet cap.
