Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

Example one

As shown in fig. 2 to 4, the present embodiment provides a combined fan rib structure, which includes a fan rib 1, a fan rib nail penetrating block 2, a necking groove 21, a necking groove fitting protrusion 10 and a constraint structure, wherein the width of the fan rib 1 is: the front end is wide and the rear end is narrow.

The fan ribs can be any one of large ribs and small ribs.

The fan bone nail penetration block 2 is provided with a pin hole 20, and the pin hole 20 is a circular hole.

The necking groove 21 is arranged on the fan rib piercing block 2, and the shape of the fan rib piercing block 2 is circular, prismatic and the like.

The necking groove matching lug 10 is arranged at the rear end part of the fan framework 1.

The notch width of the necking groove 21 is smaller than the groove bottom width of the necking groove 21, and the necking groove matching lug 10 is matched with the necking groove 21 to prevent the necking groove matching lug 10 from being separated from the notch of the necking groove 21.

The necking groove 21 is the groove bottom diameter of which the notch aperture is smaller than that of the necking groove 21.

The shape of the necking groove matching lug 10 is similar to that of the necking groove 21.

The slot-fitting projection 10 enters the slot 21 from one surface of the fan blade nailing block 2 in the thickness direction.

The structure can ensure that the anti-falling function is achieved after the two are assembled, and the structural strength in the subsequent use process is ensured.

The constraint structure is arranged between the two sides of the necking groove matching convex block 10 and the groove wall of the necking groove 21 and is used for fixing the fan rib piercing nail block 2 relative to the necking groove 21 in the thickness direction. The constraint structure can prevent the fan rib nail penetration block 2 and the fan rib 1 from mutually dislocating or even separating in the thickness direction.

Secondly, the outer diameter of the fan rib nail penetration block 2 of the embodiment is larger than the width of the rear end of the fan rib 1, so as to facilitate the drilling processing of the pin hole 20.

Preferably, the necking groove 21 of the present embodiment is a dovetail groove, and the necking groove fitting protrusion 10 is a dovetail protrusion.

The dovetail structure is convenient to process and manufacture, and can play a role in preventing the falling off in the length direction.

The thickness of the fan rib nail penetrating block 2 is equal to that of the fan rib 1, and after the outer wall is assembled, two thickness surfaces of the fan rib nail penetrating block 2 are respectively flush with two thickness surfaces of the fan rib 1. The fan ribs are ensured to be opened and closed after being stringed together, and the mutual convex obstruction interference is avoided.

The assembly method of the present embodiment includes the steps of:

The embodiment can realize mechanical connection and fixation without glue application.

Specifically, as shown in fig. 2 to 6, the constraint structure of the present embodiment includes arc convex surfaces 11 disposed on two side surfaces of the throat groove fitting protrusion 10 and disposed along the length direction of the side surfaces, arc concave surfaces 22 respectively disposed on two groove walls of the throat groove 21 and matched with the arc convex surfaces 11 one by one, and the arc convex surfaces 11 and the arc concave surfaces 22 are matched with each other.

The cooperation of the arc convex surface 11 and the arc concave surface 22 enables the fixation together in the thickness direction, prevents the dislocation in the thickness direction, namely, can make the thickness of the fan rib piercing nail block 2 and the thickness of the fan rib 1 flush in the thickness direction.

Further, the circular arc convex surface 11 includes an eccentric circular convex sub-surface 110, and a first inclined lead-in surface 111 connected to one side of the eccentric circular convex sub-surface 110. The eccentricity is the eccentric position of the corresponding side of the necking groove fitting projection 10.

Next, the first inclined lead-in surface 111 is tangent to the eccentric lobe surface 110. Convex interference is avoided.

The arc-shaped concave surface 22 comprises an eccentric circular concave sub-surface 220 matched with the eccentric circular convex sub-surface 110 and a second inclined lead-in surface 221 connected with the eccentric circular concave sub-surface 220, and the first inclined lead-in surface 111 and the second inclined lead-in surface 221 are matched together after the eccentric circular convex sub-surface 110 and the eccentric circular concave sub-surface 220 are matched together. The eccentricity is the same as that described above. The second inclined lead-in surface 221 is tangent to the eccentric circular concave sub-surface 220.

In assembly, the eccentric lobe surface 110 enters from the second inclined lead-in surface 221, and then the eccentric lobe surface 110 and the eccentric concave lobe surface 220 are mated together, and the first inclined lead-in surface 111 and the second inclined lead-in surface 221 are mated together. The assembly efficiency and the structural stability are improved.

One end of the fan framework 1 provided with the necking groove matching convex block 10 is provided with a buckling part 12 positioned at two sides of the necking groove matching convex block 10, and the buckling part 12 is buckled at a notch of a necking groove 21 of the fan framework through nail block 2.
