Description

Technical Field

[0001] This utility model relates to the field of personal care equipment technology, and in particular to a hair styling tool. Background Technology

[0002] Existing hair styling tools include curling irons, massage combs, and other hair styling products. To improve product competitiveness and reduce manufacturing costs, multiple hair styling products can share a single handle, eliminating the need to develop multiple handles. Instead, the required functional modules can be replaced at the front of the handle. These functional modules can be the curling components at the front of a curling comb, the combing components at the front of a massage comb, etc. Currently, the handle and functional modules are usually connected by a plug-in method. After long-term use, the elasticity decreases, affecting the reliability of the locking mechanism, and there is a risk that the functional modules may detach. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings and deficiencies of the existing technology and to provide a hair styling tool.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hair styling tool, including a handle and a functional module detachably connected to the front end of the handle. The front end of the handle is provided with a rotating ring that can rotate around an axis. The functional module has an insertion part that passes through the rotating ring and enters the handle, and the outer wall of the insertion part is provided with an axial limiting structure. The axial end face of the rotating ring is provided with at least one arc-shaped guide structure extending circumferentially. The arc-shaped guide structure has a guide surface that is inclined in the radial direction, so that a continuous height difference is formed between the radially inner end and the radially outer end of the arc-shaped guide structure. A radially sliding locking block is provided inside the handle. The locking block has a guide rod extending towards the rotating ring. The free end of the guide rod is embedded in the arc-shaped guide structure and slides in cooperation with the guide surface. When the rotating ring rotates, the guide surface moves circumferentially relative to the guide rod, driving the locking block to move radially up and down on the handle and form a blocking cooperation with the axial limiting structure on the outer wall of the insertion part.

[0005] As a preferred embodiment of this utility model, the arc-shaped guide structure is an arc-shaped groove or an arc-shaped hole.

[0006] As a preferred embodiment of this utility model, the arc-shaped guide structure is provided in at least two sets and is evenly distributed along the circumference of the rotating ring.

[0007] As a preferred technical solution of this utility model, the axial limiting structure is an axial limiting protrusion or an axial limiting recess provided on the outer wall of the insertion part. When the locking block is raised and lowered to the preset position, its lower part abuts against the outside of the axial limiting protrusion or is embedded in the axial limiting recess.

[0008] As a preferred embodiment of this utility model, the rotating ring is sleeved on the outside of the handle and rotates relative to the handle. The axial end face of the rotating ring is provided with a plurality of arc-shaped guide grooves evenly distributed along the circumferential direction. The handle has a guide portion extending in the direction of the arc-shaped guide groove, and the free end of the guide portion is embedded in the arc-shaped guide groove.

[0009] As a preferred embodiment of this utility model, a damping pad is fitted on the outer wall of the front end of the handle, and the inner wall of the rotating ring and the outer wall of the damping pad form a rotating pair.

[0010] As a preferred technical solution of this utility model, the front end of the handle is provided with multiple support parts, and each support part is provided with a radially extending guide groove. The locking block is slidably disposed in the guide groove, and the locking block achieves radial movement by the constraint of the guide groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: when the rotating ring rotates, the guide rod is driven by the inclined guide surface to drive the locking block to rise and fall radially, forming a blocking cooperation with the axial limiting structure of the insertion part, realizing the quick locking or unlocking of the functional module. Through the mechanical linkage between the rotating ring and the locking block, the disassembly operation steps are simplified, and it has the characteristics of compact structure and reliable locking.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1-7The hair styling tool shown includes a handle 1 and a functional module 2 (straightening comb, curling iron, massage comb, oil comb, curling iron, etc.) detachably connected to the front end of the handle 1. The front end of the handle 1 is provided with a rotating ring 3 that can rotate around an axis (the rotating ring 3 can be integrated with the functional module or set separately). The functional module 2 has an insertion part 4 that passes through the rotating ring 3 and enters the handle 1, and the outer wall of the insertion part 4 is provided with an axial limiting structure. The axial end face of the rotating ring 3 is provided with at least one arc-shaped guide structure 5 extending circumferentially. The arc-shaped guide structure 5 has a guide surface 6 that is inclined in the radial direction (in this embodiment, the arc-shaped guide structure 5 is an arc-shaped groove or an arc-shaped hole, and the guide surface 6 is the inner circumferential wall of the arc-shaped groove or arc-shaped hole). This creates a continuous height difference between the inner radial end 14 and the outer radial end 15 of the arc-shaped guide structure 5. A radially sliding locking block 7 is provided inside the handle 1. The locking block 7 has a guide rod 8 extending towards the rotating ring 3. The free end of the guide rod 8 is embedded in the arc-shaped guide structure 5 and slides in cooperation with the guide surface 6. When the rotating ring 3 rotates, the guide surface 6 moves circumferentially relative to the guide rod 8, driving the locking block 7 to move radially up and down on the handle 1 and form a blocking cooperation with the axial limiting structure of the outer wall of the insertion part 4. When the guide rod 8 is located at the inner radial end 14, the locking block 7 forms a blocking cooperation with the axial limiting structure of the insertion part 4. When the guide rod 8 is located at the outer radial end 15, the locking block 7 does not interfere with the axial movement of the insertion part 4.

[0024] When the rotating ring 3 rotates, the guide rod 8 is driven by the inclined guide surface 6 to drive the locking block 7 to rise and fall radially, forming a blocking engagement with the axial limiting structure of the insertion part 4, thereby realizing the quick locking or unlocking of the functional module 2. Through the mechanical linkage between the rotating ring 3 and the locking block 7, the disassembly operation steps are simplified, and it has the characteristics of compact structure and reliable locking.

[0025] At least two sets of arc-shaped guide structures 5 are provided and are evenly distributed along the circumference of the rotating ring 3. In this embodiment, the arc-shaped guide structures 5 are evenly distributed along the circumference, and multiple guide rods 8 are simultaneously subjected to force, reducing single-point wear and extending service life.

[0026] The axial limiting structure is an axial limiting protrusion 9 (circular) or an axial limiting recess (annular groove) set on the outer wall of the insertion part 4. When the locking block 7 is raised and lowered to the preset position, its lower part abuts against the outside of the axial limiting protrusion 9 or is embedded in the axial limiting recess. The locking block 7 and the axial limiting structure of the insertion part 4 are rigidly abutted or embedded to form a two-way mechanical lock to prevent the functional module 2 from accidentally falling off during use.

[0027] The rotating ring 3 is sleeved on the outside of the handle 1 and rotates relative to the handle 1. Several arc-shaped guide grooves 10 are evenly distributed along the circumferential direction on the axial end face of the rotating ring 3. The handle 1 has a guide part 11 extending in the direction of the arc-shaped guide groove 10. The free end of the guide part 11 is embedded in the arc-shaped guide groove 10.

[0028] The outer wall of the front end of the handle 1 is fitted with a damping pad (not shown in the picture, but can be made of materials such as rubber or silicone). The inner wall of the rotating ring 3 and the outer wall of the damping pad form a rotating pair to improve the rotation damping feel, prevent accidental unlocking, and reduce noise.

[0029] The front end of the handle 1 is provided with multiple support parts 12, and each support part 12 has a radially extending guide groove 13. The locking block 7 is slidably disposed in the guide groove 13, and the locking block 7 achieves radial movement by the constraint of the guide groove 13.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples of this utility model and are not intended to limit it. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
