Description
Technical Field
The utility model relates to the field of household appliances, in particular to a knob assembly.
Background
In many household kitchen ventilators, electric rice cookers and other electric appliances requiring time or power control, a rotary knob is required to control, and the conventional knob is generally provided with a shaft sleeve integrally in a knob body (i.e. a manually operated part), and rotation control is performed by matching the shaft sleeve with a valve body (also called a knob rod).
However, the structure can only correspond to the valve body with the same structure and the same type of electric appliances with the same rotation angle, so the inventor further research the structure and develops a knob assembly, and the structure is generated.
Disclosure of Invention
The utility model aims to provide a knob assembly which can adapt to knob installation with different heights.
In order to achieve the above object, the technical scheme of the present utility model is as follows:
a knob assembly, comprising
The knob comprises a knob body, wherein a limit round hole is formed in the knob body, a polygonal hole is formed in the limit round hole, and a step is formed between the limit round hole and the polygonal hole;
and one end of the knob shaft sleeve is matched with the limit round hole and the polygonal hole of the knob body, and the other end of the knob shaft sleeve is provided with a mounting hole which is used for matched mounting of the valve body.
The step formed between the limit round hole and the polygonal hole is used for limiting the installation depth of the knob shaft sleeve, so that the valve body is in the same depth after the knobs with different heights are installed; meanwhile, the polygonal holes can be installed in different directions, so that the relative position directions of the knob marks and the valve body can be accurately installed, and knobs in various common directions can be conveniently produced in batches.
Further, the front of the knob body is marked with an indication mark.
Further, the polygonal hole is a regular octagon.
The state that the relative position direction of the indication mark and the valve body is 0 degree, 45 degree, 90 degree, 135 degree, 180 degree, 225 degree, 270 degree and 315 degree can be accurately installed.
Further, the spring hole is formed in the side edge of the mounting hole, the spring piece is arranged in the spring hole and used for applying pressure to the valve body, and the valve body cannot be easily separated from the mounting hole.
Further, the knob body is provided with the decorative board in front, and the indicator sign is on the decorative board.
Further, the spring hole is communicated with the mounting hole, the spring piece is of an arc-shaped structure, and the protruding part of the spring piece is contacted with the valve body.
Further, the knob shaft sleeve is an insulating knob shaft sleeve.
After the scheme is adopted, compared with the prior art, the utility model has the following advantages:
the installation depth of the knob shaft sleeve is limited through the octagon and the cylindrical transition step on the knob shaft sleeve during installation, so that the knob shaft can be adapted to the same depth after the knobs with different heights are installed; the regular octagon on the insulating knob shaft sleeve and the regular octagon on the knob body are installed in different directions, so that knobs in various common directions can be conveniently produced in batches; the insulating knob shaft sleeve has the function of electric isolation, and when the product is in grounding failure or the product is in electric leakage and electrified, the operating knob is prevented from being electrified.

Detailed Description
The utility model will be further described with reference to the drawings and the specific examples.
As shown in fig. 1 and 2, a knob assembly includes a knob body 1, a knob sleeve 2, a spring plate 3, and a valve body 4, wherein the knob body 1 is integrally in a cylindrical structure, a decorative plate 5 is disposed at one end of the knob body facing a user, an indication mark 51 is disposed on the decorative plate 5, and the indication mark 51 is used for indicating a steering angle of the knob (as shown in fig. 3).
A limiting round hole 11 is formed in the knob body 1, a regular octagon is arranged in the limiting round hole 11, and a step is formed between the limiting round hole 11 and the regular octagon; the step is used for limiting the installation depth of the knob shaft sleeve 2, so that the valve body 4 is at the same depth after the knobs with different heights are installed.
As shown in fig. 4, the rotary knob mark is installed in different directions of the regular octagon, and the rotary knob mark and the valve rod can be accurately installed in the states of 0 °, 45 °, 90 °, 135 °, 180 °, 225 °, 270 ° and 315 ° relative to each other. The knob in various common directions can be produced in batches.
The knob axle sleeve 2 is provided with mounting hole 21, and mounting hole 21 is used for the cooperation installation valve body 4, and the spring hole has been seted up to the mounting hole 21 side, is provided with spring piece 3 in the spring hole, and the spring hole communicates with mounting hole 21, and spring piece 3 is the arc structure, and its bellied part contacts with valve body 4, and spring piece 3 is used for exerting pressure to valve body 4, makes valve body 4 can not break away from easily from mounting hole 21.
The knob sleeve 2 can be made of insulating materials, and can prevent the operation knob from being electrified when the electrical product fails to be grounded or the product leaks electricity.
The foregoing is only specific embodiments of the present utility model, and words such as "upper, lower, left, right, middle" and the like "related to the present utility model are merely used by way of reference, not to be construed as limiting, and any insubstantial modifications made by the present utility model shall fall within the scope of the utility model.
