Description

Technical Field

[0001] This utility model relates to the field of hair styling tools, and in particular to a hair styling tool with a quick-release structure that allows for the replacement of different functional modules. Background Technology

[0002] With the diversification of hair styling needs, hair styling tools with replaceable functional modules are gradually gaining market favor due to their convenience and versatility. In existing technology, the functional modules of hair styling tools (such as straighteners, curling irons, and curling iron components) are typically connected by threads or snap-fit ​​mechanisms. However, this type of structure has significant drawbacks: firstly, threaded connections require multiple rotations, resulting in low assembly and disassembly efficiency and wear over long-term use; secondly, the way the elastic element and snap-fit ​​mechanism engage often leads to stress concentration, causing elasticity to diminish over time and affecting the reliability of the locking mechanism. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a hair styling device based on a quick-release structure that allows for the replacement of different functional modules.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hair styling tool with a quick-release structure and interchangeable functional modules, including a handle and a functional module detachably connected to the front end of the handle. A rotating cover is rotatably mounted on the front end of the handle, and a locking panel is fixedly connected to the front end of the rotating cover. The locking panel has a central insertion hole, and the inner wall of the central insertion hole extends radially to form at least one L-shaped locking groove. The locking groove includes an axially extending guide groove and a circumferential locking groove communicating with it. The functional module includes an insertion part adapted to the shape of the central insertion hole. The outer wall of the insertion part has at least one radially protruding locking block. The locking block can be inserted axially along the guide groove, and the locking panel is rotated by the rotating cover to make the locking block enter the circumferential locking groove to achieve circumferential locking.

[0005] As a preferred embodiment of this utility model, the locking panel extends toward one end of the handle to form an annular positioning cylinder, the insertion hole is disposed through the positioning hole, and the locking groove is formed in the annular positioning cylinder.

[0006] As a preferred embodiment of this utility model, the locking groove is provided in two sets and symmetrically arranged in the annular positioning cylinder, and the corresponding locking block is provided in two sets and symmetrically distributed at 180°.

[0007] As a preferred technical solution of this utility model, the locking panel includes an outer periphery, and a clearance groove is formed between the outer periphery and the annular positioning cylinder. The locking panel is provided with a plurality of connecting holes along the circumferential direction corresponding to the position of the annular groove. The rotating cover is provided with a plurality of connecting posts corresponding to the positions of the connecting holes, and each connecting post is provided with an axial threaded hole.

[0008] As a preferred embodiment of this utility model, the inner wall of the rotating cover is provided with an annular support section, and the outer periphery of the locking panel enters the rotating cover and abuts against the annular support section.

[0009] As a preferred embodiment of this utility model, an axial limiting structure is provided between the rotating cover and the handle. The axial limiting structure includes an annular groove on the inner circumference of the handle, and a limiting flange that cooperates with the outer wall of the rotating cover.

[0010] As a preferred technical solution of this utility model, the functional component is any one of a hair straightener, a curling iron, or an egg roll head component.

[0011] Compared with the prior art, the beneficial effects of this utility model are: through the linkage design of the rotating cover and the locking panel, combined with the axial introduction and circumferential locking dual-stage structure of the L-shaped locking groove, the functional module can be installed by "inserting and turning", and the disassembly and assembly time is shortened to within 3 seconds. The efficiency is significantly improved compared with the traditional threaded connection, and no additional pressing pressure is required during the locking process. Attached Figure Description
