In order to achieve the above purpose, the present utility model provides the following technical solutions:
the utility model provides a novel knob structure, includes injection moulding's knob shell, is provided with the cover on the knob shell and establishes the portion, and the junction that knob shell established the portion with the cover is formed with first step face, overlaps to establish to be equipped with on the portion with knob linkage complex silica gel cover, arranges on the outer peripheral face of silica gel cover and is provided with the contact, the bottom and the first step face butt of silica gel cover.
Preferably, the top end of the silica gel sleeve is provided with a second step surface, the knob shell is provided with a ring cover, and the ring cover is abutted with the second step surface.
Preferably, a button is provided in the knob housing, the button being movably disposed with respect to the knob housing.
Preferably, the knob comprises a knob shell, a base which is axially clamped with the knob shell, and a button which is slidably matched with the base and can be axially slidably arranged along the base.
Preferably, the inner peripheral surface of the base is provided with a plurality of sliding grooves, and the outer peripheral surface of the button is provided with sliding blocks which are arranged corresponding to the sliding grooves.
Preferably, the button includes a first pressing portion and a second pressing portion.
The utility model has the beneficial effects that:
1. the silicon rubber sleeve and the knob shell are adopted to assemble to replace the research and development of a knob double-color mold structure, and the mold is changed from double colors to single-color molds, so that the manufacturing difficulty is greatly reduced, and the development cost investment is greatly reduced;
2. defects such as parting lines, burrs and the like of parts can be effectively avoided, and appearance quality is greatly improved;
3. different touch requirements of customers can be met, and the hardness of the silica gel sleeve can be adjusted according to the proportion of the formula;
4. the limitation of the injection molding temperature of the mold on the silica gel material can be effectively avoided, the material selectivity of the silica gel sleeve is wider, and the cost reduction degree of parts is larger;
5. the problem of insufficient binding force between silica gel and plastic caused by unreasonable injection parameters of a double-color mold can be avoided.
