Description
Technical field
The utility model relates to a kind of rotary switch structure.
Background technology
Rotary switch assembly is all there is in a lot of existing household electrical appliance, rotary switch assembly generally comprises knob body and encoder component, encoder component has a footstalk, knob body has an installing hole, the mounting structure of existing structure is generally on shell, offer one first through hole, and interference is connected between installing hole with footstalk, and encoder component is fixedly mounted on shell; Existing mounting structure has following defect: do not have direct matching relationship between knob body and shell, knob body is caused easily to swing when rotary work, and operationally also can swing due to the footstalk of encoder component, knob body work is caused to wave jumping phenomena more obvious, have a strong impact on the experience of client, also be unfavorable for the smooth and easy regulation stall of client simultaneously, give the impression that product quality does not pass a test.The utility model provides a kind of rotary switch structure of compact conformation for this reason.
Utility model content
In order to solve the problem, the utility model provides a kind of rotary switch structure of compact conformation.
The utility model solves the technical scheme that its technical problem adopts:
A kind of rotary switch structure, comprise knob body, shell and encoder component, encoder component has a footstalk, and knob body side is provided with an installation shaft, is provided with an installing hole for being connected with footstalk, installation shaft sidewall is provided with back-off in installation shaft; Described shell is provided with one first through hole, the sidewall of the first through hole is provided with vertically the gathering sill of at least one degree of depth gradual change, the gathering sill interference fit at back-off and the most shallow place of the degree of depth; Encoder component is installed in the enclosure.
Described knob body opposite side is provided with circular fold, and on described shell, corresponding circular fold place is provided with annular groove.
The side of the end that described footstalk is connected with installing hole is provided with a burnishing surface, to being provided with confinement block by burnishing surface in described installing hole.
The far-end of described installation shaft is provided with some breach.
The quantity of described gathering sill is set to two, and the quantity of corresponding back-off is also set to two.
Be provided with some erection columns inside described shell, described erection column is provided with screwed hole, described encoder component is provided with the second through hole, in described second through hole and screwed hole, be equipped with screw.
The beneficial effects of the utility model are: adopt knob body and shell in the utility model of said structure to be linked together by the first through hole and installation shaft, installation shaft is connected with footstalk by installing hole again, the waving when cooperation between the first through hole and installation shaft can be rotated knob body is beated and is well limited, simultaneously matched in clearance between installing hole and footstalk, can reduce waving that footstalk passes over further and beat.Visible knob body of the present utility model waves the amplitude of beating when rotating minimum, working stability, and customer experience sense is splendid, and knob body regulates good hand touch.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is generalized section of the present utility model;
Fig. 2 is decomposing schematic representation of the present utility model;
Fig. 3 is the schematic diagram of the utility model shell.
Embodiment
With reference to Fig. 1 ~ Fig. 3, the utility model is a kind of rotary switch structure, comprise knob body 1, shell 2 and encoder component 3, encoder component 3 has a footstalk 4, knob body 1 side is provided with an installation shaft 5, being provided with an installing hole for being connected with footstalk 4 in installation shaft 5, installation shaft 5 sidewall being provided with two back-offs 6; Sidewall shell 2 being provided with one first through hole 7, first through hole 7 is provided with vertically the gathering sill 8 of two degree of depth gradual changes, gathering sill 8 interference fit at back-off 6 and the most shallow place of the degree of depth; Encoder component 3 is arranged in shell 2.
Knob body 1 and shell 2 in the utility model of said structure is adopted to be linked together by the first through hole 7 and installation shaft 5, installation shaft 5 is connected with footstalk 4 by installing hole 13 again, the waving when cooperation between the first through hole 7 and installation shaft 5 can be rotated knob body 1 is beated and is well limited, simultaneously matched in clearance between installing hole 13 and footstalk 4, can reduce waving that footstalk 4 passes over further and beat.Visible knob body of the present utility model 1 waves the amplitude of beating when rotating minimum, and working stability, customer experience sense is splendid, and knob body 1 regulates good hand touch.
As shown in the figure, in order to increase the stability of utility model works further, knob body 1 opposite side is provided with circular fold 9, on shell 2, corresponding circular fold 9 place is provided with annular groove 10, can prevent waving of knob body 1 from beating by circular fold 9 further with coordinating of annular groove 10.
As shown in the figure, for the ease of back-off 6 smoothly by gathering sill 8, the far-end in installation shaft 5 is provided with two breach 11, so can be this end and provides partial elastic, so that the installation of back-off 6.
As shown in the figure, the side of the end that footstalk 4 is connected with installing hole 13 is provided with a burnishing surface 12, to confinement block should be provided with by burnishing surface 12 in installing hole 13, installing hole 13 so can be facilitated to be connected with the fast pulldown of footstalk 4.Be provided with some erection columns 14 inside shell 2, erection column 14 is provided with screwed hole, encoder component 3 is provided with the second through hole, in the second through hole and screwed hole, be equipped with screw 15; So can fast encoder component 3 be arranged on shell 2.
Above-described embodiment is preferred version of the present utility model, and the utility model also can have other embodiments.Those skilled in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent modification or replacement are all included in the scope set by the application's claim.
