Embodiment
Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figures 2 and 3, Fig. 2 is the structural representation of knob in the utility model preferred embodiment, and Fig. 3 is the partial structurtes schematic diagram of knob in the utility model preferred embodiment.
The knob 100 that this embodiment proposes, comprises by flat sidewall A and cambered surface sidewall B and surrounds connecting hole 10 that connecting hole 10(the present embodiment surrounds take a flat sidewall A and cambered surface sidewall B as example, and the present embodiment is elaborated).The medial surface of connecting hole 10 is provided with the lug boss 11 for increasing the magnitude of interference, even while making or turn column dimension oversize at connecting hole 10 too small, because at least one position of the sidewall of turn post is connected on lug boss 11, connecting hole 10 also can be socketed on turn post very closely, and can not cause loose or dislocation.Certainly, hindered by lug boss 11 for fear of turn post and can not insert in connecting hole 10, lug boss 11 is made as to the first spigot surface 111 near one end end face (calling " lug boss 11 top end faces " in the following text) of connecting hole 10 entrances, the first spigot surface 111 is cambered surface, or is the inclined plane that is acute angle with described connecting hole 10 medial surfaces.Connecting hole 10 is provided with the breach 12 from its arrival end to downward-extension, breach 12 is communicated with medial surface and the lateral surface of connecting hole 10, the sidewall that makes connecting hole 10 by breach 12 is set is open-type, can produce elastic dilatation deformation based on breach 12, even while making or turn column dimension undersized at connecting hole 10 excessive, also can connecting hole 10 sizes be expanded by connecting hole 10 sidewall elastic dilatation deformation, thereby make knob 100 and the installation of turn post light, convenient.
The knob 100 that the present embodiment proposes, owing to thering is the lug boss 11 that increases the magnitude of interference and the breach 12 that makes connecting hole 10 variable sizes, make knob 100 connecting hole 10 can with the tight fit of turn post of sizes size, the dimension precision requirement of knob 100 connecting holes 10 reduces, be that production technology reduces, yields promotes (can reach under normal circumstances 100% yields) greatly, has significantly reduced scrap cost; And mount and dismount all convenient, fast, significantly improved the production efficiency of the product that uses this knob 100.
Further, in order further to reduce installation difficulty, thereby improve installation effectiveness, the arrival end end face of the connecting hole 10 of the present embodiment is connected by the second spigot surface 13 with the medial surface of connecting hole 10.Because the guiding by the second spigot surface 13 makes, the arrival end of knob 100 more easily docks with turn post, has therefore facilitated the installation of knob 100.The second spigot surface 13 is cambered surface or is the inclined plane being tilted to connecting hole 10 medial surfaces by the arrival end end face of connecting hole 10.
Further, the present embodiment is arranged on cambered surface sidewall B as example take breach 12, and the present embodiment is set forth.Because the restorative deformation compared to flat sidewall A of deformation of cambered surface sidewall B is restorative better, so the present embodiment is arranged on breach 12 on cambered surface sidewall B.Breach 12 can be one or more, is not easy to be squeezed by turn post bad in order to guarantee the intensity of connecting hole 10 sidewalls, and the present embodiment adopts a breach 12, and breach 12 is located at the centre position of cambered surface sidewall B so that breach 12 both sides stressed evenly.So both can guarantee the intensity of connecting hole 10 sidewalls, and can guarantee again the tightness that is connected of connecting hole 10 and turn post.
Further, lug boss 11 can be raised line or projection, the present embodiment selects lug boss 11 to be arranged on flat sidewall A, and the raised line of selecting two vertical connecting hole 10 bottom surfaces to arrange is example, and two raised lines are symmetrically distributed in the both sides of breach 12, so that connecting hole 10 sidewalls is stressed more even.Certainly the quantity of raised line can also be 1,3,4 or more, and it is upper that raised line also can be arranged on cambered surface sidewall B, and it is upper upper compared to being arranged on cambered surface sidewall B that raised line is arranged on flat sidewall A, the stressed meeting of sidewall of connecting hole 10 more all and some.
Further, long and by connecting hole 10 side wall lower ends (connecting hole 10 positions that breach 12 does not extend in order to prevent that turn post from inserting length in connecting hole 10, be connecting hole 10 side wall lower ends parts or closed type) rack or cause dismounting difficulty, the present embodiment convexes with the end face location division 14 concordant with breach 12 bottoms in the bottom surface of connecting hole 10.Knob 100 when mounted, is connected on knob 100 press sleeves on turn post, and when knob 100 can not be continuing while depressing to turn post direction, installation personnel just can know and be in place, turn post with location division 14 butts.
Be appreciated that the first spigot surface 111 in the present embodiment and the second spigot surface 13 can also have for other structural plane of guide effect, are not only confined to cambered surface described above and inclined plane.
As shown in Figure 4 and Figure 5, Fig. 4 is the structural representation of the switch member body of the utility model knob 100 switch member, and Fig. 5 is the structural representation of the utility model rotary switch part.
With reference to Fig. 2 to Fig. 5, the utility model also proposes a kind of knob 100 switch member, comprises switch member body 200 and the knob 100 with turn post 20, and the connecting hole 10 of knob 100 is socketed in the first end of turn post 20.This knob 100 can comprise all technical schemes of previous embodiment knob 100, and its detailed construction can, with reference to previous embodiment, not repeat at this.Concrete, the first end end face 21 of turn post 20 is connected by the 3rd spigot surface 22 with the lateral surface of turn post 20, so that turn post 20 is lighter, quick with the installation of connecting hole 10.The 3rd spigot surface 22 is arcwall face, or the 3rd spigot surface 22 is the inclined plane being tilted to the lateral surface of turn post 20 by the first end end face 21 of turn post 20.Be appreciated that the 3rd spigot surface 22 can also have for other structural plane of guide effect, is not only confined to cambered surface described above and inclined plane.
Owing to having adopted the scheme of knob 100 in previous embodiment, the utility model knob 100 switch member are compared to existing rotary switch part, and aborning, the yields of knob 100 promotes greatly, and scrap cost significantly reduces; And knob 100 is lighter with the installation and removal of switch member body 200, more convenient and quicker, and production efficiency significantly promotes.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
