Detailed description of the invention
In order to technical characteristic of the present utility model, purpose and effect are more clearly understood from, now comparison accompanying drawing describes detailed description of the invention of the present utility model in detail.
As shown in Figure 1 and Figure 2, the electronic equipment in one preferred embodiment of this utility model includes knob cap construction of switch, and knob cap construction of switch adopts knob cap spring slice fixing structure 10 to carry out knob cap 11 installing location.Electronic equipment can be the electronic device in the fields such as industrial electronic, consumer electronics, household electrical appliances, automotive electronics, and knob cap switch can be the rotary knob such as code switch, volume switch.
In certain embodiments, knob cap spring slice fixing structure 10 includes knob cap 11, axle sleeve 12 and rotating shaft 13.Knob cap 11 is provided with axis hole 111；Axle sleeve 12 is plugged in the axis hole 111 of knob cap 11, axle sleeve 12 includes with axis hole 111 inwall coordinates body 121 and the elastic holding section 122 being arranged on body 121 to stretch out in the middle part of axis hole 111.Rotating shaft 13 plugs in axle sleeve 12, and elastic holding section 122 is engaged on the sidewall of rotating shaft 13.
When mounted, first axle sleeve 12 is inserted in axis hole 111, then rotating shaft 13 is inserted in axle sleeve 12, rely on the elastic force of elastic holding section 122 rotating shaft 13 to be clamped, increase rotating shaft 13 and extract the power of needs.There is elastic holding section 122, it is possible to reduce frictional force between rotating shaft 13 outer wall and axle sleeve 12 inwall when design, it is simple to rotating shaft 13 is installed, and improves efficiency of assembling, reduces cost, reduces assembling risk, can prevent again rotating shaft 13 from extracting easily.
The sidewall of rotating shaft 13 is provided with mean for the draw-in groove 131 that elastic holding section 122 snaps in, promotes the dynamics needed when axle sleeve 12 is deviate from rotating shaft 13 further, can prevent rotating shaft 13 from deviating from axle sleeve 12 easily.
Shown in Fig. 3, elastic wall 1221 that elastic holding section 122 includes being bent to center by body 121, the card being connected to elastic wall 1221 external part combine harmoniously 1222 and be connected to that card combines harmoniously that 1222 one end relative with elastic wall 1221 extend laterally outward setting keep out wall 1223.Keeping out the bootable rotating shaft 13 of wall 1223 and be inserted in axle sleeve 12, reduce the insertion dynamics of rotating shaft 13, after rotating shaft 13 is inserted, card combines harmoniously and 1222 snaps onto in draw-in groove 131, and countershaft 13 axially positions, and increases dynamics when rotating shaft 13 is extracted, it is prevented that outwards extract easily.In other embodiments, it is possible to wall 1223 will be kept out and cancel, arranging guide portion 132 in the end of rotating shaft 13 facilitates rotating shaft 13 to insert.
Preferably, keep out wall 1223 and be positioned at the end, outer end of axle sleeve 12, and extend laterally outward the outer ring protruding body 121, the profile so keeping out wall 1223 place end will be bigger than one end profile inserted, when being assembled in axis hole 111, wall 1223 place end will not will be kept out install to the inner of axis hole 111 due to by mistake dress.
Extend laterally owing to keeping out wall 1223, in order to avoid the axis hole 111 with knob cap 11 is interfered, axis hole 111 sidewall is provided with when outwards deforming for elastic holding section 122 and the escape groove 112 dodging space is provided, make elastic holding section 122 movable in deformation range.
Further, power is deviate from when axis hole 111 deviate from by axle sleeve 12 in order to increase, body 121 is provided with and protrudes from outside wall surface and offset with axis hole 111 inwall the lobe 123 coordinated, after axle sleeve 12 is inserted into axis hole 111, lobe 123 can compress with the inwall of axis hole 111, increase frictional force, it is prevented that axle sleeve 12 is deviate from easily.
In certain embodiments, lobe 123 includes the sidewall by body 121 and outwards turns down the agnail formed, agnail is towards the outer end of axis hole 111 and be that angle is arranged with the sidewall of body 121, axle sleeve 12 can be easy to and be inserted in axis hole 111, also can make agnail that the sidewall of elastic force and axis hole 111 can be relied on to offset, increase frictional force each other, allow axle sleeve 12 be not easy to deviate from.In other embodiments, lobe 123 is alternatively the structures such as the salient point of outwardly setting.
It is to be appreciated that above-mentioned each technical characteristic can use and unrestricted in any combination.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in scope of patent protection of the present utility model.
