Abstract
The utility model discloses a touch induction type keystroke used spring. An induction spring used by the present touch induction type keystroke is composed of a column-shaped spring and an induction piece, and the assembly takes time; the product cost is high; the work efficiency is low; the labor force is increased; in addition, when the induction piece is deformed or the surface is uneven, the contact area of a touch piece and a faceplate can be reduced, and then the sensitivity of touch induction is affected, a keystroke even fails. The touch induction type keystroke used spring comprises a spring body. The touch induction type keystroke used spring is characterized in that the lower part of the spring body forms a spiral shape; the upper part of the diameter is small and the lower part of the diameter is large; the upper head face of the spring body is provided with a positioning pin connected with the spring body into a whole; and the positioning pin is used for connecting the spring body and the keystroke. The spring body is compressed during work, the lower part is changed to a plane shape from the spiral shape, the contact area of the spring body and the faceplate is large, and therefore the spring body plays a role of induction sensitivity.
Description
Technical field
The utility model relates to the parts of household electrical appliance with controller, specifically a kind of touch-induction-type button spring.
Background technology
The existing used controller of household electrical appliance is often used the touch-induction-type button, its used induction spring is formed (as shown in Figure 3) by cylindric spring 3 and sensing chip 4, because cylindric spring is compressed into a circle when work, little with the contact area that connects key, be difficult to play the effect of induction, so must could use (contact area of sensing chip and panel is big) being contained on the button after cylindric spring and the sensing chip riveting together, both time-consuming, the product cost height, inefficiency, increased the labour again, distortion appears in sensing chip in addition or surface irregularity can cause that the contact area that touches sheet and panel reduces, thereby influence the sensitivity of touch sensible, even cause that button is malfunctioning.
The utility model content
Technical problem to be solved in the utility model is to overcome the defective that above-mentioned prior art exists, and a kind of touch-induction-type button spring that need not to assemble is provided, and it can be directly installed on the button, to accelerate operating efficiency, reduces the labour.
For this reason, the utility model adopts following technical scheme: touch-induction-type button spring, comprise spring body, the bottom that it is characterized in that spring body is shape in the shape of a spiral, diameter is up-small and down-big, one angle that is connected as a single entity with it is arranged on upper surface of spring body, and angle is used for being connected of spring body and button.During work, spring body is compressed, and its underpart is by helical form complanation shape, and the contact area of spring body and panel is big, thereby plays the sensitive effect of induction.
As the further of technique scheme improved and replenish, the utility model is taked following technical measures:
Above-mentioned touch-induction-type button spring, angle is direct rod shape or cylindric, also can adopt other analogous shape.
Above-mentioned touch-induction-type button spring, angle and spring body are on same center line, and be stable when making spring work, the reliability height.
Above-mentioned touch-induction-type button spring, the first half of spring body are cylindric or whole spring body shape in the shape of a spiral, from the working stability angle, select above-mentioned shape with the contact area and the machining angle of panel.
The utlity model has following beneficial effect: need not to adorn sensing chip, reduced this link of assembling, both reduced product cost, reduced the labour, accelerated operating efficiency again; Stable during work, reliability is high.
Below in conjunction with specification drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is an another kind of structural representation of the present utility model.
Fig. 3 is the structural representation of existing touch-induction-type button with spring.
Embodiment
Touch-induction-type button spring as shown in Figure 1, the top of spring body 1 is cylindric, the bottom is shape in the shape of a spiral, diameter is up-small and down-big, one angle that is connected as a single entity with it 2 is arranged on the upper surface of spring body 1, angle 2 is direct rod shape, and it is used for being connected of spring body 1 and button, and angle and spring body are on same center line.During work, spring body is compressed, and its underpart is by helical form complanation shape, thereby makes the contact area of spring body and panel big, plays the sensitive effect of induction.
Embodiment 2
Touch-induction-type button spring as shown in Figure 2, embodiment 2 is with the difference of embodiment 1: angle 2 is cylindric, and its diameter is less than the external diameter of spring body upper surface.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all falls in the protection range of the present utility model any simple modification, equivalent variations and modification that above embodiment did.
Claims (5)
1, touch-induction-type button spring comprises spring body, and the bottom that it is characterized in that spring body is shape in the shape of a spiral, and diameter is up-small and down-big, and an angle that is connected as a single entity with it is arranged on upper surface of spring body.
2, touch-induction-type button spring according to claim 1 is characterized in that described angle is direct rod shape or cylindric.
3, touch-induction-type button spring according to claim 1 and 2 is characterized in that angle and spring body are on same center line.
4, touch-induction-type button spring according to claim 1 is characterized in that the first half of spring body is cylindric.
5, touch-induction-type button spring according to claim 1 is characterized in that whole spring body shape in the shape of a spiral, and diameter is up-small and down-big.
