Description

Technical Field

[0001] The utility model relates to the technical field of rivets, in particular to detachable rivets. Background Technique

[0002] A rivet is a fastener used to connect two or more objects, and they are widely used in various fields such as construction, machinery manufacturing, aerospace, etc. The selection of rivets usually depends on factors such as the material, thickness, connection strength requirements of the objects to be connected, and the use environment. Different types of rivets have different characteristics and application ranges. For example, solid rivets, hollow rivets, semi-hollow rivets, etc. When using rivets, it is necessary to select the appropriate type of rivet and installation method according to specific situations to ensure the reliability and safety of the connection.

[0003] Existing rivets usually consist of a head and a shank. The head can be round, flat or other shapes. The shank passes through the objects to be connected and is fixed at the other end by riveting or other means. The function of the rivet is to provide a firm connection and can withstand a certain amount of tensile force, shear force and pressure.

[0004] However, for existing rivets, most of their components are fixedly connected, which results in their inability to be disassembled when replacement or maintenance is required, increasing the costs of maintenance and replacement, and may limit their flexibility and reusability in specific applications in some cases. Therefore, detachable rivets are proposed to solve the above problems. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a detachable rivet, aiming to improve the problem that it is impossible to disassemble conveniently in the prior art, resulting in the need for overall replacement during replacement.

[0006] To achieve the above object, the detachable rivet includes an expansion part. A nail core is slidably connected inside the expansion part. A clamping groove is formed inside the expansion part. A rivet sleeve is slidably connected to the outer wall of the nail core. A sleeve is arranged inside the rivet sleeve. A moving rod is slidably connected inside the nail core. A first spring is sleeved on the outer wall of the moving rod. One end of the first spring is fixedly connected inside the nail core. The other end of the first spring is fixedly connected with a limiting ring. The outer wall of the limiting ring is slidably connected inside the nail core. One end of the moving rod is fixedly connected with a conical block. The moving rod is slidably connected with a sliding column. A second spring is sleeved on the outer wall of the sliding column. One end of the second spring is fixedly connected to the outer wall of the sliding column. The other end of the second spring is fixedly connected inside the nail core. The outer wall of the sliding column is slidably connected inside the clamping groove. A pulling assembly is arranged on the outer wall of the moving rod, and the pulling assembly is used to pull the moving rod.

[0007] Optionally, the pulling assembly includes a fixed block and a limiting block, the interior of the fixed block is fixedly connected to the outer wall of the moving rod, and the interior of the limiting block is fixedly connected to the interior of the moving rod.

[0008] Optionally, a warping gap is opened inside the sleeve, and a fixing ring is fixedly connected to the outer wall of the sleeve.

[0009] Optionally, a connecting groove is provided inside the fixing ring, and an outer wall of the connecting groove is slidably connected to the inside of the rivet sleeve.

[0010] Optionally, an elastic shift block is fixedly connected to the outer wall of the rivet sleeve, and a limiting groove is provided inside the rivet sleeve.

[0011] Optionally, a movable column is slidably connected inside the limiting groove, and a spring three is sleeved on the outer wall of the movable column.

[0015] 1. In the utility model, the sliding column realizes its moving function by pulling the moving rod. When the moving rod is pulled, the structures such as the spring, the slot and the conical block will be linked accordingly to realize the disassembly of the expansion part. After the rivet is fixed, it can be disassembled for secondary use, which solves the problem of directly cutting off the nail core after the rivet is fixed, saving costs.

[0016] 2. In the utility model, the slider realizes its clamping function by pulling the movable column. When the movable column is pulled, the connecting groove, the elastic paddle, the spring and other structures will be linked accordingly to realize the disassembly of the rivet sleeve, which can meet different usage requirements. The appropriate sleeve can be selected according to the actual situation, which solves the problem that the sleeve and the rivet sleeve are fixed to each other and cannot be conveniently replaced, thereby improving the convenience of the device.
