Description

Technical Field

[0001] This utility model belongs to the field of hair dryer technology, specifically relating to a rotatable and foldable hair dryer handle. Background Technology

[0002] A foldable hair dryer handle is a foldable hair dryer component that significantly reduces the overall size of the hair dryer when folded, making it easy to put into a suitcase, backpack, etc., saving space and making it suitable for travel, business trips, or carrying when going out.

This folding method has poor stability and is prone to folding due to swinging during use. Moreover, after long-term use, the limiting structure is prone to fatigue, resulting in problems such as incomplete folding or loosening after folding.

[0004] Therefore, a rotatable and foldable hair dryer handle was designed to overcome the aforementioned technical shortcomings. Utility Model Content

Detailed Implementation

[0027] This specific embodiment is a rotatable and foldable hair dryer handle, the structural diagram of which is shown below. Figures 1-7 As shown, it includes a body 1 and a handle 2. Two connecting plates 3 are fixedly connected to the side wall of the body 1. Two rotating shafts 4 are fixedly connected to the side wall of the handle 2 near the top. The rotating shafts 4 are rotatably connected to the connecting plates 3 on both sides respectively. A positioning component is provided on the side wall of the handle 2, and a rotating component is provided at the bottom of the handle 2.

[0028] like Figure 3 and Figure 7 As shown, the positioning component includes a groove 5 formed on the side wall of the handle 2. A first spring 6 is fixedly connected to the side wall of the groove 5. A locking block 7 is fixedly connected to the other end of the first spring 6. Two slots 8 are formed on the side wall of the connecting plate 3 located on the lower side and the left side of the rotating shaft 4. The two slots 8 are concentric with the rotating shaft 4. The locking block 7 is adapted to the slot 8. A reset component is provided in one of the slots 8.

[0029] The included angle between the two slots 8 is 60°-90°, which makes it easy to unfold the handle 2 to a suitable angle, making it more comfortable for the user to hold.

[0030] like Figure 5 As shown, the end face of the card block 7 has an arc-shaped structure, and the depth of the lower card slot 8 is greater than the depth of the left card slot 8.

[0031] Specifically, when the handle 2 is in the folded state, the locking block 7 is inserted into the shallower slot 8, and the first spring 6 is in a slightly compressed state. When the handle 2 is pulled, the locking block 7 can be pulled out of the slot 8. When the locking block 7 is inserted into the deeper slot 8, pulling the handle 2 will not pull the locking block 7 out of the slot 8, thus achieving the purpose of stable use.

[0032] like Figure 7 As shown, the reset assembly includes a movable rod 9 movably connected to the side wall of the connecting plate 3. One end of the movable rod 9 near the locking block 7 extends into the locking groove 8 and is fixedly connected to a push plate 10. The other end of the movable rod 9 is fixedly connected to a pressure plate 11. A second spring 12 is sleeved on the side wall of the movable rod 9.

[0033] When folding, the pressure plates 11 on both sides can be pressed with fingers to push the locking block 7 out of the deeper locking groove 8, thereby ensuring that the handle 2 has high stability and avoiding loosening or folding of the handle due to shaking during use, thus effectively improving its performance.

[0034] like Figure 4 and Figure 7 As shown, a torsion spring 18 is fitted to the side wall of the pivot 4. The torsion spring 18 facilitates the folding and resetting of the handle 2, eliminating the need for manual pressing, thus offering high practicality and flexibility.

[0035] like Figure 5 and Figure 7 As shown, the rotating assembly includes a limiting ring 14 rotatably connected to the bottom of the handle 2, and a sealing gasket 15 and a flexible gasket 16 are fixedly connected to the inner wall of the limiting ring 14.

[0036] Specifically, the sealing gasket 15 is an upwardly inclined annular gasket, and the flexible gasket 16 is composed of multiple small gaskets arranged in a circular array. During assembly, the blower wire needs to pass through the sealing gasket 15 and the flexible gasket 16. The sealing gasket 15 is used for waterproofing, and the flexible gasket 16 is used to limit the wire and keep it in a centered state, reducing problems such as wire insulation layer cracking caused by bending and twisting.

[0037] like Figure 6 As shown, a sealing ring 17 is fitted to the side wall of the limiting ring 14, and the sealing ring 17 abuts against the side wall of the handle 2. The sealing ring 17 is used to ensure good sealing between the sealing ring 17 and the handle 2 during rotation, preventing moisture from entering and affecting the service life of internal components. A rotating ring 13 is rotatably connected to the bottom surface of the limiting ring 14. The rotating ring 13 is used to support the wires, and the inner wall of the rotating ring 13 has an arc-shaped structure, which can reduce wear.

[0038] Working principle: When it is necessary to open and use the handle 2, the handle 2 can be pulled directly. When the locking block 7 is subjected to force, it disengages from the left locking slot 8. At the same time, the first spring 6 and the torsion spring 18 are compressed. When the handle 2 is rotated to 90°, the rebound of the first spring 6 drives the locking block 7 to lock into the lower locking slot 8, which is used to limit the handle 2. Since the lower locking slot 8 is relatively deep, even when the handle 2 is subjected to force, the locking block 7 will not disengage from the locking slot 8, so as to ensure stable use.

[0039] When the handle 2 needs to be folded, press the pressure plates 11 on both sides, and the movable rod 9 will drive the push plate 10 to push the locking block 7, so that the locking block 7 is disengaged from the slot 8. At the same time, the return of the torsion spring 18 will drive the handle 2 to return to its original position, thus achieving the purpose of folding. After releasing the pressure plate 11, the locking block 7 will be inserted into the shallower slot 8 for auxiliary fixation.

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
