Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As shown in Figures 1 to 4, this knob assembly, the fixed pedestal 2 comprising knob 1 and can match with described knob 1, described knob 1 is provided with axle sleeve 11, described fixed pedestal 2 is provided with the positioning sleeve 21 that can match with axle sleeve 11, in the described positioning sleeve 21 of the rotating insertion of described axle sleeve 11, described axle sleeve 11 is provided with ring-type draw-in groove 12, positioning sleeve 21 inwall of described fixed pedestal 2 is provided with the claw 22 corresponding with described ring-type draw-in groove 12, and when described axle sleeve 11 and positioning sleeve 21 match, described claw 22 is fastened in described ring-type draw-in groove 12.
In this programme, when described knob 1 and fixed pedestal 2 assemble, by closely cooperating of positioning sleeve 21 that the axle sleeve of described knob 1 11 and fixed pedestal 2 are arranged, achieve the positioning function of knob assembly.
In this programme, when the positioning sleeve 21 that the axle sleeve 11 of described knob 1 and fixed pedestal 2 are arranged closely cooperates, after the axle sleeve 11 of above-mentioned knob 1 inserts the positioning sleeve 21 that fixed pedestal 2 is arranged, the ring-type draw-in groove 12 that axle sleeve 11 is arranged will run into the claw 22 be arranged on positioning sleeve 21, and ring-type draw-in groove 12 and claw 22 mutually block with, realize the self-locking of knob and pedestal.
So this knob assembly adopts single version to have self-locking and positioning function, and structure and assembling mode are simply, and production cost is low, and what solve knob rocks eccentricity issues.
In the present embodiment, preferably, described ring-type draw-in groove 12 is arranged around the whole excircle of axle sleeve 11.Described claw 22 is positioned on the inwall of described positioning sleeve 21.The number of described claw 22 is minimum is two, preferably, can be 3,4,5 etc. more.
In the present embodiment, as another kind of preferred version, described ring-type draw-in groove 12 is arranged around the whole excircle of axle sleeve 11.The end of described positioning sleeve 21 is provided with at least one pair of symmetrical claw arm 23, each described claw arm 23 is provided with a described claw 22.In the present embodiment, preferably, the end of described positioning sleeve 21 is connected with a pair symmetrical claw arm 23.But the number of described claw arm 23 can also be 2 to, 3 equities.
In the present embodiment, as another preferred version, described claw 22 is made up of elastomeric material, and its shape is triangle, and its cross-sectional area increases progressively along the direction of insertion of axle sleeve 11, and wherein, leg-of-mutton elastic card claw 22 has guide effect.
In the process that axle sleeve 11 inwardly advances, when contacting with claw 22, pushing claw arm 23 deforms, after together with corresponding to ring-type draw-in groove 12 when claw 22, under the effect of elastic force, claw arm 23 resilience makes claw 22 be fastened in ring-type draw-in groove 12, at this moment the claw 22 because arranging is triangle, and its cross-sectional area increases progressively along the direction of insertion of axle sleeve 11, and claw 22 cannot be extracted from ring-type draw-in groove 12 inside and outside again, cause knob to extract in fixed pedestal 2 again, be in self-locking state.When needs are dismantled time, in inside by slightly firmly making it be out of shape to both sides claw arm 23, knob can be released.
In the present embodiment, preferably, described fixed pedestal 2 is provided with boss 24, and described boss 24 back side is provided with positioning sleeve 21, and described positioning sleeve 21 is positioned at the center of described boss 24.
