Detailed Description
For a better understanding of the objects, structure and function of the invention, reference should be made to the drawings, which are illustrated in fig. 1-8.
The knob 1 of most fans in the market has poor operation hand feeling, only adopts interference fit for installation, is easy to pull out during operation, and is not foolproof during installation and alignment, so that the knob 1 is inconvenient to install and wastes working hours; further, when electrical components such as the "rotary switch 3" and the like are mounted to the knob 1, the components need to be fixed by screws, which is time-consuming and inconvenient in mounting operation.
The design provides a rotary switch subassembly, including knob 1 that has round bolt 106 and the shell 2 of seting up through-hole 202, knob 1 inserts rotatory regulation in the through-hole 202 through round bolt 106 to round bolt 106 on the 1 terminal surface of knob has a plurality of first spacing buckles 103 as central annular distribution connection, wherein, first spacing buckle 103 is strip structure and wedge structure built-up connection structure, and strip structure fixes on the terminal surface of knob 1, and the assembly card of being convenient for is steady.
Utilize a plurality of first spacing buckles 103 to be elastomeric element material and geometric characteristics, along with during knob 1 inserts through-hole 202, force a plurality of first spacing buckles 103 to receive the extrusion and be close to each other the shrink, aim at again and get into through-hole 202 in, the spacing joint of first spacing buckle 103 that gets into in through-hole 202 is on shell 2 under the resilience effect. The problem of inconvenient installation of electrical components such as rotary switch 3 with knob 1 complex is solved to realize easy to assemble and the inseparable effect of cooperation.
On the other hand, the mounting fool-proof significance of the knob 1 is very large, for example, for the fan, the fan has two options of shaking and not shaking, a gear indication mark is arranged on the knob 1, if the mounting direction of the knob 1 is just opposite, the indication mark on the knob 1 indicates that the whole fan is in a shaking state instead of a shaking state, and indicates that the whole fan is in a shaking state instead of a shaking state, in this case, the knob 1 needs to be pulled out and remounted, and mounting operation time is wasted invisibly.
Therefore, the design is further improved, the outer side wall of the limiting column 303 is simultaneously connected with a large limiting rib 301 and a small limiting rib 302, and the large limiting rib 301 and the small limiting rib 302 are positioned on the same diameter extension line of the limiting column 303; the round bolt 106 is simultaneously provided with a large limiting notch 102 and a small limiting notch 101, the large limiting notch 102 and the large limiting rib 301 are matched and clamped in a limiting mode, the small limiting notch 101 and the small limiting rib 302 are matched and clamped in a limiting mode, and the mounting fool-proof effect of the knob 1 is achieved.
