Detailed Description

The technical scheme of the utility model is further described below with reference to the attached drawings and specific embodiments.

Example 1

As shown in fig. 1 and 3, the lock pin blind rivet provided by the utility model comprises a rivet structure composed of a rivet body 1 and a pin 2, the pin 2 comprises a core bar main body 21, the top of the core bar main body 21 is provided with a pin end head for plugging and fixing, and the bottom end of the core bar main body 21 is integrally provided with a connector 24 for conveniently disassembling the rivet structure.

The working principle of the blind rivet with the locking nail head based on the first embodiment is as follows: when the product is used, holes are drilled on the structural part, then the rivet body 1 of the rivet structure is inserted into the riveting holes, and then a rivet pulling gun for self-plugging rivets is used for pulling and riveting. After riveting and pulling riveting, the upper end part of the rivet core 2 of the rivet structure is broken and left and is buried in the rivet body 1, so that the fastening of the structural member is realized. In this case, if the assembly position of the structural member is to be adjusted, the already-fixed rivet structure is to be detached. If the operation space is narrow and the electric drill is difficult to detach the rivet structure, the broken rivet core 2 is inserted into the rivet body 1 through the connector 24, and then the broken rivet core 2 positioned in the rivet body 1 is connected through the connector 24. And then the nail core 2 is impacted by a foreign object, so that the nail core 2 positioned in the rivet body 1 is punched by the nail core 2, and the disassembly of the nail core is completed.
