Abstract
The utility model discloses a knob which comprises a cylindrical knob base (1). A spindle base (2) is arranged at the position of the center of the inner end face of the knob base (1) and provided with an axial hole (3). A circumferential direction limitation device is arranged in the axial hole (3). At least one radial opening (4) penetrating through the wall of the spindle base (2) is arranged on the spindle base (2) so that when a knob shaft is inserted into the axial hole, the opening is firstly expanded to be open. Accordingly, a spindle base body is not caused to crack. Therefore, the normal use of the knob is ensured, and the work reliability of the knob is improved.
Description
Technical field
The utility model relates to the device commonly used on a kind of household electrical appliance, specifically is a kind of knob.
Background technology
The knob of prior art comprises the cylindrical shape knob base, and the center of the inner face of described cylindrical shape knob base is provided with shaft seat, is provided with axial hole in the described shaft seat, is provided with circumferential stop means in the described axial hole.There is following defective in the knob of said structure in the use of reality: since axial hole need with the rotation axis wringing fit on the household electrical appliance, therefore axial hole is adding need reduce axial hole and rotation axis man-hour as far as possible gap, but so when inserting axial hole, rotation axis easily cause the body of shaft seat to break, thereby influence the normal use of knob, make the functional reliability of knob reduce.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, and the knob that causes that the knob base body breaks is provided when providing a kind of rotation axis to insert axial hole.
The technical solution of the utility model is, a kind of knob is provided, comprise columnar knob base, the center of described knob base inner face is provided with shaft seat, be provided with axial hole in the described shaft seat, be provided with circumferential stop means in the described axial hole, described shaft seat is provided with at least one radially and opening that run through the shaft seat wall thickness.
After adopting above structure, the utility model compared with prior art has the following advantages:
The shaft seat of the utility model knob is provided with at least one radially and opening that run through the shaft seat wall thickness, like this when rotation axis inserts axial hole, can at first strut this opening, and can not cause the shaft seat body to break, thereby guaranteed the normal use of knob, made the functional reliability of knob improve.
As improvement, described number of openings is two, and two openings can guarantee better that the shaft seat body is unlikely and break, thereby further improves the functional reliability of knob.
As improvement, described circumferential stop means is meant a plurality of axially extended radial groove that is located on the axial hole inwall, can guarantee turning axle and axial hole wringing fit better by this radial groove, thereby improves the functional reliability of knob.
Description of drawings
Accompanying drawing is the structural representation of the utility model knob.
Shown in the figure 1, knob base, 2, shaft seat, 3, axial hole, 4, opening, 5, radial groove.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in drawings, a kind of knob of the utility model comprises columnar knob base 1, and the center of described knob base 1 inner face is provided with shaft seat 2, and is gapped between described knob base 1 inner headed face and shaft seat 2 peripheries; Be provided with axial hole 3 in the described shaft seat 2, be provided with circumferential stop means in the described axial hole 3, described shaft seat 2 is provided with at least one radially and opening 4 that run through shaft seat 2 wall thickness.
The quantity of described opening 4 is two.
Described circumferential stop means is meant a plurality of axially extended radial groove 5 that is located on axial hole 3 inwalls.The periphery of described knob base 1 is provided with the projection that increases friction.
Below only be described, but can not be interpreted as it is restriction claim with regard to most preferred embodiment of the present utility model.The utility model is not limited only to above embodiment, and its concrete structure allows variation.In every case the various variations of being done in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
Claims (3)
1. knob, comprise columnar knob base (1), the center of described knob base (1) inner face is provided with shaft seat (2), be provided with axial hole (3) in the described shaft seat (2), described axial hole is provided with circumferential stop means in (3), it is characterized in that: described shaft seat (2) is provided with at least one radially and opening (4) that run through shaft seat (2) wall thickness.
