Abstract
The utility model relates to a volume adjusting knob, wherein the volume adjusting knob sleeves the rotating shaft of a potentiometer, the rotating shaft of the potentiometer passes through a panel to extend out, one side of the volume adjusting knob, opposite to the panel is provided with an annular projection, the position on the panel, corresponding to the annular projection is provided with an annular groove, the annular projection is arranged inside the annular groove, and when the volume adjusting knob is rotated, the annular projection on the knob slides in the annular groove on the panel, and the annular groove limits the swaying of the annular projection, thereby limiting the overlarge swaying of the volume adjusting knob in the process of rotation. The annular groove and the annular projection match with each other to play an excellent effect of limiting the swaying of the knob, and thereby the diameter of the knob can be made larger, the arm of force between the larger knob and the rotating shaft of the potentiometer can be longer, and the force required for rotating the volume adjusting knob can be smaller.
Description
Technical field
The utility model relates to stereo set, especially volume adjustment knob.
Background technology
Volume adjustment knob is connected with the rotating shaft of potentiometer, drives the potentiometer rotating shaft through rotary knob and rotates, thereby reach the purpose of regulating volume.Owing to leave the space between potentiometer rotating shaft and the panel; When equipment in when broadcast, small vibrations can appear in potentiometer, during the rotation volume adjustment knob; Knob has significantly and departs from; This amplitude that departs from becomes big and becomes big along with the knob diameter, and therefore existing volume adjustment knob is generally done smallerly, and the volume adjustment knob of minor diameter need spend bigger strength when rotating.
Summary of the invention
The utility model technical problem to be solved provides a kind of volume adjustment knob, and volume adjustment knob can do more, and has overcome the excessive phenomenon of major diameter volume adjustment knob vibrations.
For solving the problems of the technologies described above, the technical scheme of the utility model is: a kind of volume adjustment knob, said volume adjustment knob are enclosed within the rotating shaft of potentiometer, and the rotating shaft of said potentiometer is passed panel and stretched out; The one side that said volume adjustment knob is relative with said panel is provided with annular protrusion, and corresponding said annular protrusion place is provided with annular groove on the said panel, and said annular protrusion is located in the said annular groove.During the rotation volume adjustment knob, the annular protrusion on the knob can slide in the annular groove on panel, and annular groove has limited the swing of annular protrusion, occurs excessive swing when rotated thereby limited volume adjustment knob.Because cooperatively interacting of annular groove and annular protrusion played the effect of good restriction knob swing, therefore can the diameter of knob be done more, the arm of force between the rotating shaft of big knob and potentiometer is longer, and the needed power of rotation volume adjustment knob is just littler.
As improvement, said panel is provided with guide vane end stop, and said knob is provided with block, and said guide vane end stop cooperates with said block, and the amplitude that the restriction volume adjustment knob rotates is excessive and damage potentiometer.
As improvement, said knob is provided with sleeve, and the rotating shaft of said potentiometer is located in the said sleeve.
As improvement, the distance between the rotating shaft end face of said potentiometer and the said cover tube bottom is 0.5 ~ 1.0mm.The rotating shaft of potentiometer and the distance between the knob guarantee that the annular protrusion of knob can touch the annular groove of panel earlier, prevent that knob from touching potentiometer rotating shaft end face earlier and being elevated, and produce swing.
As improvement, be provided with damping oil in the said annular groove, through add damping oil plastic part at interval in the Support Position, prevent direct contact, utilize the viscosity of damping oil to cushion the vibrations between the plastic cement simultaneously.
The beneficial effect that the utility model is compared with prior art brought is:
Because cooperatively interacting of annular groove and annular protrusion played the effect of good restriction knob swing, therefore can the diameter of knob be done more, the arm of force between the rotating shaft of big knob and potentiometer is longer, and the needed power of rotation volume adjustment knob is just littler; Through add damping oil plastic part at interval in the Support Position, prevent direct contact, utilize the viscosity of damping oil to cushion the vibrations between the plastic cement simultaneously.

Embodiment
Below in conjunction with Figure of description the utility model is described further.
Like Fig. 1, shown in 4; A kind of volume adjustment knob; The rotating shaft 5 of the potentiometer of stereo set is passed panel 4 and is stretched out, and said volume adjustment knob 1 is provided with sleeve 8, and volume adjustment knob 1 is enclosed within the connection of accomplishing the two in the rotating shaft 5 of potentiometer and fixes through sleeve 8; After volume adjustment knob 1 was inserted in the rotating shaft 5 of potentiometer, rotating shaft 5 end faces of potentiometer and the distance between the said cover tube bottom were 0.5mm.Like Fig. 2,3, shown in 5; Said volume adjustment knob 1 is provided with annular protrusion 2 with said panel 4 relative one sides; Corresponding said annular protrusion 2 places are provided with annular groove 3 on the said panel 4, and said annular protrusion 2 is located in the said annular groove 3, and is provided with damping oil in the said annular groove 3.Said panel 4 is provided with guide vane end stop 6, and said volume adjustment knob 1 is provided with block 7, and said guide vane end stop 6 cooperates with said block 7, and the amplitude that restriction volume adjustment knob 1 rotates is excessive and damage potentiometer.
During rotation volume adjustment knob 1, the annular protrusion 2 on the knob can slide in the annular groove 3 on panel, and annular groove 3 has limited the swing of annular protrusion 2, occurs excessive swing when rotated thereby limited volume adjustment knob 1.Because annular groove 3 plays the effect that good restriction knob is swung with cooperatively interacting of annular protrusion 2; Therefore can the diameter of knob be done more; The arm of force between the rotating shaft 5 of big knob and potentiometer is longer, and rotation volume adjustment knob 1 needed power is just littler.Through between annular groove 3 and annular protrusion 2, adding damping oil, prevent the two direct contact, utilize the viscosity of damping oil to cushion the vibrations between the plastic cement simultaneously; And the sound that shakes during the work of the different sound of friction generates and audio amplifier between plastic cement and the plastic cement when damping oil can prevent to rotate improves feel.
