Description

Technical Field

[0001] The invention belongs to the field of fans, and in particular relates to a flip assembly and a fan. Background Art

[0002] As a new category of fans on the market, folding fans are widely loved by consumers for their foldable storage and easy carrying as their biggest selling point. The core component of folding fans is their retractable telescopic rod, which is folded with a rotating mechanism. General folding fans are single-rod retractable, and use rubber springs to control the strength of the machine head's pitch and shake. But the bad thing is that silicone springs are prone to failure after multiple compressions, and are easy to wear and have a short lifespan. The pitch structure of the silicone spring is suitable for lighter machine heads. A heavier machine head can easily cause the silicone spring to fail and be unable to support the machine head's tilt. Summary of the invention

[0007] Furthermore, the rotating piece includes a convex point, and the braking position includes a concave position for the convex point to be inserted.

[0008] Furthermore, the concave positions and convex points are arranged in a circular array along the rotation axis.

[0026] In order to better understand the purpose, structure and function of the present invention, a flip assembly and a fan of the present invention are further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1As shown, the fan of the present invention comprises a head 1 and a support rod 2. Two support rods 2 are provided, and the head 1 is mounted between the two support rods 2. The support rod 2 adopts a sleeve structure to achieve telescopic. In order to facilitate folding the fan and adjusting the air outlet direction of the head 1, the head 1 is connected to the support rod 2 through a flip assembly to adjust the angle of the head 1.

[0028] like Figure 2 As shown, the flip assembly includes a first sleeve 3 fixed on the support rod 2, and a rotating piece 4 fixed on the machine head 1; when the random head 1 rotates on the support rod 2, the rotating piece 4 and the first sleeve 3 rotate relative to each other; the first sleeve 3 is provided with at least two braking positions, and an elastic member is provided on the side of the rotating piece 4 away from the braking position; when the elastic member drives the rotating piece 4 to engage with the braking position, the machine head 1 and the support rod 2 are fixed; when the elastic member contracts, the rotating piece 4 and the braking position are separated, and the machine head 1 rotates relative to the support rod 2 to adjust the angle.

[0029] In order to facilitate the contraction of the driving elastic member, the rotating plate 4 is provided with a driving inclined surface, and the braking position is provided with a driving conical surface that fits the driving inclined surface. In this way, by manually rotating the machine head 1, the inclined surface force is utilized to contract the elastic member, thereby separating the engaging member and the braking position.

[0030] Specifically, the rotating piece 4 is a bead-touching piece, the rotating piece 4 is provided with a convex point 41, and the braking position is a concave position 341 for the convex point 41 to be inserted.

[0031] Combination Figure 3 As shown, in order to facilitate the provision of a recess 341 on the first sleeve 3, the recess 341 is formed on the front side of the positioning piece 34, and a clamping rib 342 arranged along the normal direction is formed on the back side of the positioning piece 34. The first sleeve 3 is provided with a clamping hole 31 for the clamping rib 342 to be inserted.

[0032] Furthermore, in order to facilitate the provision of sufficient braking positions, the concave positions 341 and the convex points 41 are arranged in a circular array along the rotation axis, thereby ensuring that the rotating plate 4 and the braking positions are firm.

[0033] Combination Figure 4 As shown, in addition to the bead-touching piece and the positioning piece 4, the rotating piece 4 is a tooth piece, and a positioning tooth 42 is formed on one side of the tooth piece, and the braking position is a tooth groove 32 for the positioning tooth 42 to engage.

[0034] In order to ensure that the elastic member sufficiently drives the rotating plate 4 , the elastic member is an elastic gasket 5 .

[0035] In order to fix the rotating piece 4 and the machine head 1, the machine head 1 is provided with a first positioning hole 11, the edge of the rotating piece 4 is provided with a protruding rib 43 extending in the radial direction, and the inner wall of the first positioning hole 11 is provided with a positioning groove 111 for the protruding rib 43 to be inserted into. Thus, the rotating piece 4 and the elastic member are installed in the first positioning hole 11.

[0036] In order to fix the first sleeve 3, the upper end of the support rod 2 is clamped with a first joint 6, the first joint 6 is provided with an axial hole 61, the first sleeve 3 is provided with a fixed shaft 33, the fixed shaft 33 passes through the first positioning hole 11, and the rotating piece 4 and the elastic member in the first positioning hole 11 are inserted into the axial hole 61, and the first joint 6 is screwed to the fixed shaft 33. In order to prevent the fixed shaft 33 from rotating, the fixed shaft 33 and the axial hole 61 are polygonal.

[0037] Generally, the rotating piece 4 and the first sleeve 3 only need to be arranged on one side of the machine head 1, and the other side of the machine head 1 and the machine head 1 mainly realize rotation.

[0038] like Figure 5 As shown, the flip assembly also includes a second sleeve 7 fixed on another support rod 2, and the second sleeve 7 is provided with a fixing sleeve 71; the other side of the machine head 1 is provided with a second positioning hole 12 for the fixing sleeve 71 to pass through. A second joint 8 is clamped on the support rod 2, and the second joint 8 and the fixing sleeve 71 are screwed.

[0039] In order to prevent the second sleeve 7 from rotating, the second joint 8 is provided with a buckle 81 around the fixing sleeve 71 . The outer wall of the fixing sleeve 71 is formed with a positioning hole 711 for the buckle 81 to pass through, and the buckle 81 is engaged with the second positioning hole 12 .

[0040] In order to realize the wiring, the second joint 8 and the second sleeve 7 are hollow. The second joint 8 and the fixing sleeve 71 are formed with eccentrically arranged threaded columns on the inner wall, and the threaded columns are provided with threaded holes for screw thread connection, so that the second joint 8 and the fixing sleeve 71 are screwed.

[0041] In order to improve appearance, the joint is clamped with a cover 9 that covers the screws.

[0042] In summary, of the two support rods 2 of the fan, the flip assembly on one is used to adjust the angle, and the flip assembly on the other is hollow and is used for wiring.
