Detailed Description

To make the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

A fan of this embodiment, please refer to fig. 1 to 2, which includes a head assembly and a pitch structure. The head assembly comprises a mesh enclosure, and fan blades are arranged inside the mesh enclosure. The handpiece assembly may be conventional in the art and is not shown. Every single move structure includes installing support 4 and articulated seat 1, and head assembly fixed mounting is on installing support 4. Articulated seat 1 includes first casing 11 and second casing 12, and first casing 11 is detachable connection structure with second casing 12 to first casing 11 and second casing 12 are U type structure, can realize dismantling the connection through the screw, the installation of the pitch structure of being convenient for.

Referring to fig. 3 to 5, the hinge base 1 extends upward to form a first suspension arm 2 and a second suspension arm 3 spaced apart from each other in a horizontal direction, and the mounting bracket 4 is rotatably mounted between the first suspension arm 2 and the second suspension arm 3. Specifically, the mounting bracket 4 extends out of the hinge portion towards the first suspension arm 2, and the first suspension arm 2 is provided with a hinge hole 21, and the hinge portion is inserted into the hinge hole 21 and can rotate around the hinge hole 21. Preferably, the hinge portion is a hinge sleeve 5 formed on the outer side surface of the first suspension arm 2, and the hinge sleeve 5 and the mounting bracket 4 are of an integrally formed structure, and have high structural strength and are easy to manufacture.

In order to prevent the hinge portion from falling off the first suspension arm 2, the outer circumferential side of the hinge sleeve 5 is provided with a hinge groove 51, and the groove width of the hinge groove 51 is greater than or equal to the hole depth of the hinge hole 21, so that the hinge sleeve 5 is held in the hinge hole 21, and the outward end portion of the hinge sleeve 5 is held in the end portion of the hinge hole 21, thereby preventing the hinge sleeve 5 from falling off. In order to improve the rotational fluency between the hinge sleeve 5 and the hinge hole 21, the hole wall of the hinge hole 21 protrudes to form at least one circle of convex ring 211 arranged along the circumferential direction of the hinge hole 21, and the inner annular surface of the convex ring 211 is a circular arc surface. Through the convex ring 211 with the arc surface, the surface contact between the hinge sleeve 5 and the hinge hole 21 is changed into line contact, the contact area is reduced, the friction force between the hinge sleeve and the hinge hole is reduced, and the rotation fluency is improved.

In order to limit the rotation range of the mounting bracket 4, the end of the hinge sleeve 5 may be inserted through the hinge hole 21 and into the first suspension arm 2, and a stopper rib 22 disposed along the axial direction of the hinge sleeve 5 is formed in the first suspension arm 2. The end of the hinge sleeve 5 extends outward to form a stopper 52, and the stopper 52 may be a semicircular ring formed at the end of the interface sleeve. After the mounting bracket 4 rotates 90 degrees, the limiting part 52 abuts against the limiting rib 22, and the rotation range of the mounting bracket 4 is limited between the forward rotation 90 degrees and the reverse rotation 90 degrees.

In this embodiment, a hinge is fixedly connected to a side of the mounting bracket 4 facing the second suspension arm 3, and the hinge is inserted into the second suspension arm 3 and can rotate relative to the second suspension arm 3. A damping mechanism may also be provided between the mounting bracket 4 and the second boom 3. Specifically, the hinge is a hinge screw 61, and the mounting bracket 4 is fixedly mounted with a hinge nut 62. Preferably, the mounting bracket 4 is formed with a mounting groove 41 at an inner side surface thereof, and the hinge nut 62 is seated in the mounting groove 41, and the mounting groove 41 is used to restrict the rotation of the hinge nut 62. When the hinge screw 61 is coupled to the hinge nut 62, the hinge nut 62 does not rotate by rotating the hinge screw 61. The second boom 3 is formed with a counter bore 31 aligned with the hinge nut 62. In the assembled state, after the hinge screw 61 is inserted into the counter bore 31, the head of the hinge screw 61 is caught in the counter bore 31, and the threaded section of the shaft of the hinge screw 61 is threadedly coupled to the hinge nut 62.

In order to enable the mounting bracket 4 to be fixed at an angle, a damping mechanism is provided between the mounting bracket 4 and the second boom 3. Referring to fig. 6, in the present embodiment, the damping mechanism includes a flat gasket 71 and three elastic gaskets 72, and each of the elastic gaskets 72 and the flat gasket 71 is sequentially sleeved on the outer side of the hinge screw 61. The elastic gasket 72 and the flat gasket 71 are pressed by the locking force generated by the cooperation of the hinge screw 61 and the hinge nut 62, and sufficient friction force is generated between the mounting bracket 4 and the second cantilever 3, so that the mounting bracket can be stably pitched or fixed at a certain rotation angle. The other side of the mounting bracket 4 limits the rotation range of the limiting sleeve through the limiting rib 22, and the working stability of the pitching structure is further improved.

The fan structure every single move structure of this embodiment, the structure is simpler compact to make the assembly consuming time short, reduced intensity of labour and human cost, improved production efficiency. The pure extrusion force generated between the hinged screw and the hinged nut is adopted, so that the mounting bracket and the cantilever are matched to generate friction force to realize pitching, lubricating oil does not need to be smeared, the wear is not easy to occur, the service life is longer, and the cost performance is higher.

Although the embodiments disclosed in the present application are described above, the descriptions are only for facilitating the understanding of the present application, and are not intended to limit the present application. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the disclosure as defined by the appended claims.
