Abstract
The utility model discloses a multifunction switch keycap, which is an umbrella-shaped structure with a disc-shaped upper end and a column-shaped lower end and comprises a fixing plate and a pressure spring. An operation spindle bar at the upper end of the multifunction switch is inserted in the column-shaped lower end of the keycap, the fixing plate is arranged between the internal side of the disc-shaped upper end of the keycap and the upper end of the multifunction switch, and the pressure spring is sleeved on the column-shaped lower end of the keycap. The fixing plate is a flange with the upper end projecting and the lower end extending radially, the outer edge of the flange is evenly distributed with a plurality of projecting lugs which extend radially, and the projecting lugs are in clearance fit with an electric appliance shell guide groove in which the multifunction switch is disposed. The multifunction switch keycap has simple structure and convenient use, overcomes the shortcoming that the existing keycaps upside down and laterally swings freely, is not easy to drop off, and prolongs the service life.
Description
Technical field
The utility model relates to a kind of operating parts of multi-direction switch, relates in particular to a kind of keycap structure of multi-direction switch, belongs to Electronic Control product accessories technical field.
Background technology
At present, the advantage that multi-direction switch (four-way, five is to switch) is little with its volume, switching function is many obtains application more and more widely at each electric appliances in the remote controller of especially all kinds of household electrical appliance.The operating parts of multi-direction switch is the umbrella shape keycap of discoid body lower end, upper end column mostly, and the lower end of this keycap is provided with the blind hole that cooperates with multi-direction switch upper end operating axis club head, and keycap is connected with operating axis club head tight fit.Because the top-heavy structural instability of keycap, also because the gap of multi-direction switch causes keycap to do freely swinging up and down, of long duration, loosening easily between keycap and the operating axis club head, cause keycap to be dismantled easily, thereby keycap is lost easily, make troubles to the user, child is had potential safety hazard.
The utility model content
In order to overcome the defective of prior art, the utility model provide a kind of assembling simple and direct, convenient, use reliably, neither quick detachable, also can not make the keycap of swing up and down, to improve the reliability that remote controller uses.
The utility model is achieved by the following technical programs:
A kind of multi-direction switch keycap, described keycap is the beveled structure of discoid body lower end, upper end column, the operation axostylus axostyle of multi-direction switch upper end is plugged in the lower end column of described keycap, also comprise fixed head, stage clip, described fixed head is arranged between described keycap discoid body inboard, upper end and the multi-direction switch upper end, and described compression spring sleeve is contained on the column of keycap lower end.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid a kind of multi-direction switch keycap, wherein said fixed head are the flange that radially extend projection lower end, upper end, and several lugs that radially extend, described lug and the electric appliance casing gathering sill matched in clearance that multi-direction switch is housed evenly distribute on the described flange outer rim.
The utility model utilizes the axial elasticity power of stage clip owing to set up stage clip between keycap downside and multi-direction switch upside, has overcome swinging up and down of multi-direction switch; Between discoid body inboard, keycap upper end and multi-direction switch upper end, set up the fixed head of flange shape, utilize the lug of fixed head to cooperate with guiding between the shell gathering sill, overcome swinging of multi-direction switch; Because the flange of fixed head must be installed in shell outwardly, makes fixed head spacing and not quick detachable by shell.The utility model is simple in structure, easy to use, has solved the existing keycap work disadvantage that freely swings up and down, and the keycap difficult drop-off has prolonged useful life.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is that existing multi-direction switch keycap is contained in the structural representation on the multi-direction switch;
Fig. 2 is that the utility model is contained in the structural representation on the multi-direction switch.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
The multi-direction switch of present embodiment is five to switch, and this five electrical equipment of installing to switch is remote controller.
As shown in Figure 1, existing multi-direction switch keycap 1 is the beveled structure of upper end discoid body 11 lower end columns 12, and five are installed on the wiring board 6 to switch 5, installing hole 31 matched in clearance of lower end column 12 and shell 3.The five operation axostylus axostyles 51 to switch 5 upper ends are plugged in the blind hole 121 of lower end column 12 of multi-direction switch keycap 1, though connect for tight fit between the two, but because multi-direction switch keycap 1 top-heavy cause and five is to the effect of the gap of switch 5, cause multi-direction switch keycap 1 can do freely swinging up and down, cause it to dismantle easily, come off.
As shown in Figure 2, the utility model also comprises fixed head 2, stage clip 4 except comprising the multi-direction switch keycap 1 that is made of upper end discoid body 11, lower end column 12.The multi-direction switch of present embodiment is five to switch 5, and this five is installed on the wiring board 6 to switch 5, installing hole 31 matched in clearance of lower end column 12 and shell 3.This five operation axostylus axostyle 51 to switch 5 upper ends is plugged in the blind hole 121 of lower end column 12 of multi-direction switch keycap 1, fixed head 2 is arranged on upper end discoid body 11 inboards and five between switch 5 upper ends, the flange that fixed head 2 radially extends for projection lower end, upper end, 4 lugs 22 that radially extend that evenly distribute on flange 21 outer rims, described lug 22 with five remote controller shell gathering sill 31 matched in clearance to switch are housed.Stage clip 4 is sleeved on the keycap lower end column 12, and the upper end of stage clip 4 withstands on the inboard of keycap upper end discoid body 11, the lower end abutment of stage clip 4 five on switch 5.
Fixed head 2 of the present utility model can use transparent or semitransparent material, is convenient to produce various light guide effects.
In addition to the implementation; the utility model can also have other execution modes; as be used to be installed in the four-way switch on other electrical equipment or operate the switch that axostylus axostyle adopts swinging operation; all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of the utility model requirement.
