Description

Technical Field

[0001] The utility model relates to the technical field of rivets, in particular to a rivet used for thin parts. Background Art

[0002] Rivets are a type of fastener and a crucial component of various mechanical equipment, securing multiple workpieces together. Rivets for thin parts are mechanical connectors specifically designed for these applications, connecting parts through their own deformation. Structurally, the rivet head can have a flat head, a semicircular head, a countersunk head, or other special shapes. The shank is slender and short, and the tail deforms during riveting. Made primarily of lightweight, high-strength materials like aluminum alloy and titanium alloy, rivets are widely used to connect thin parts in aerospace, electronic equipment, automotive manufacturing, and other fields.

[0003] Existing rivets for thin parts use their own deformation to directly clamp onto the thin parts from both sides during use. However, traditional rivets only rely on simple mechanical deformation to fix. During the operation of mechanical equipment, due to long-term vibration, impact, temperature changes and complex stress environments, the friction between the rivet and the thin part will gradually decrease, and the connection is prone to loosening. This loosening phenomenon will cause the riveting effect of the rivet to deteriorate, making the connection between thin parts no longer tight and gaps appear. Loose rivets may also generate additional friction and collision with surrounding parts during vibration, causing wear of parts and further deteriorating the operating condition of mechanical equipment. To this end, we propose a rivet for thin parts. Utility Model Content

[0004] The main purpose of the utility model is to provide a rivet for thin parts, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a rivet for thin parts, comprising a rivet body, the rivet body comprising a rivet head, a first cylinder, a second cylinder, a column head and a rivet rod, one side of the rivet head is fixedly connected to the first cylinder, the outer wall of the first cylinder is fixedly connected to the second cylinder, the rivet head is fixedly sleeved with the rivet rod relative to one side of the first cylinder, the rivet head is provided with an anti-slip component on one side surface of the first cylinder, and the anti-slip component comprises a first anti-slip pad, a protrusion and a sleeve hole, a sleeve hole adapted for the first cylinder is opened at the center position of the first anti-slip pad, and the first anti-slip pad is sleeved on the surface of the first cylinder through the sleeve hole, and the first anti-slip pad is fixedly connected to the side of the first anti-slip pad facing the first cylinder, and there are multiple protrusions.

[0006] Preferably, the surface of the first cylinder comprises an end portion, a strip, a dividing groove and a second anti-slip pad, one side of the end portion is fixedly connected to a strip, and there are multiple strips, the strip is fixedly connected to a rivet head on one side relative to the end portion, a dividing groove is provided between the strips, and the outer side wall surface of the strip is fixedly connected to a second anti-slip pad.

[0007] Preferably, the surface of the rivet body is coated with a corrosion-resistant layer.

[0008] Preferably, a column head is fixedly connected to one side of the second cylinder relative to the first cylinder, and the column head is conical.

[0009] Preferably, the first anti-slip pad and the second anti-slip pad are both made of rubber.

[0010] Preferably, the diameter of the first cylinder is greater than the diameter of the second cylinder, and the second cylinder presents a gradual design from the head to the tail.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model realizes enhanced stability of the connection between the rivet and the thin part by arranging a first anti-slip pad, a protrusion, a sleeve hole and a second anti-slip pad on the first cylindrical body to cooperate with each other, arranging an anti-slip component with a protrusion on one side of the rivet head, and arranging a second anti-slip pad on the strip of the first cylinder. During use, when the rivet is subjected to vibration or external force, these anti-slip structures can effectively increase friction, prevent the rivet from loosening, ensure the reliable connection of the thin parts, and improve the safety and stability of the entire mechanical structure.

[0013] 2. The utility model forms a gradient cylinder by setting a first cylinder and a second cylinder of different diameters. The gradient cylinder is easier to pass through the mounting hole of a thin part, reducing damage to the hole wall of the part. At the same time, the first cylinder with a larger diameter can provide a firmer support after riveting, thereby enhancing the strength of the entire riveted structure. The lower part of the cylinder is divided into multiple strips by a separation groove on the main body of the first cylinder, thereby achieving stress dispersion of the rivet when it is subjected to forces in different directions. When the thin part is subjected to complex external forces, the structure of the strips and the separation grooves can evenly distribute the force on the rivet, avoiding stress concentration, reducing the possibility of deformation or damage of the rivet due to excessive local force, and further improving the reliability and durability of the rivet connection.

A sleeve hole 303 adapted to the first cylinder 4 is opened at the center of the first anti-slip pad 301, and the first anti-slip pad 301 is sleeved on the surface of the first cylinder 4 through the sleeve hole 303. A protrusion 302 is fixedly connected to the side of the first anti-slip pad 301 facing the first cylinder 4, and there are multiple protrusions 302; when the rivet passes through the thin part, the first anti-slip pad 301 contacts the surface of the thin part, and the characteristics of the rubber material enable it to better fit the surface of the part, preventing the rivet head 2 from sliding relative to the part during use, thereby improving the stability of the rivet after fixation.

[0023] The surface of the rivet body 1 is coated with a corrosion-resistant layer 8. By coating the corrosion-resistant layer 8 on the surface of the rivet body 1, the rivet is protected from corrosion, its service life is extended, and the long-term reliability of the connection of thin parts is guaranteed.
