Description

Technical Field

[0001] The utility model relates to a shoelace head that is not easy to fall off, in particular to a shoelace head that is not easy to fall off. Background Art

[0002] Shoelace heads are also called rope flowers, which refer to the metal or plastic sleeves at the ends of shoelaces. Rope flowers can help us thread shoelaces better.

[0003] For example, the authorization announcement number "CN218418667U" is a shoelace head that is not easy to fall off. Rivets are also arranged on the side wall of the sleeve groove. The slot includes a long slot and a clamping slot. A radial slot is arranged between the long slot and the clamping slot. The shoelace head structure has a very convenient installation and assembly design. The shoelace rope is placed between the bottom cover and the pressure cover, and then the two are merged, and the sleeve cover is sleeved on the outside of the two. Through the active cooperation of the rivet and the clamping slot, a spring-based locking is realized, so that the shoelace head and the shoelace rope can be quickly and firmly connected and assembled. When replacement or disassembly is required, the reverse operation is performed. The shoelace head can be quickly separated without tools, and the user can install and disassemble it by themselves after mastering the operation method. However, the function of the shoelace head is to reduce the volume of the end of the shoelace, so as to facilitate the shoelace to pass through the round opening of the shoe. When the shoelace head is used, an elastic structure can be used in conjunction with a clamp to seal the shoelace head. Since a spring is arranged inside and it is a double-layer shell, the volume of the shoelace head is increased, which makes it easy for the shoelace head to conflict with the round opening of the shoe and cannot pass through, so that the shoelace head can only meet the use of specific shoes, resulting in the use of the shoelace head being limited and unable to meet the use of a variety of shoes.
