For: locking shifting block is provided with at least one projection, is provided with at least one groove in housing,
Described projection be able to be placed in this groove.
As a further improvement on the present invention, described locking shifting block and volume potentiometer
The structure that knob can be connected together is: the knob of volume potentiometer is coaxial with a gear
Being connected, described locking shifting block can linear slide be positioned in housing, locks shifting block court
Be provided with tooth bar to volume potentiometer side, described tooth bar can engage location with gear.
As a further improvement on the present invention, described gear is spur gear, and tooth bar is oblique
Tooth bar.
As a further improvement on the present invention, described locking shifting block can linear slide be determined
The structure being positioned at housing is: locking shifting block is provided with elongate holes, is provided with in housing
Alignment pin, described alignment pin is just inserted in described elongate holes.
As a further improvement on the present invention, described regulating key is solid with locking shifting block
Even, described regulating key being respectively provided on two sides with for finger along locking shifting block glide direction
The depression of pressing.
The method have the benefit that: the present invention is arranged in the housing of player
Locking shifting block, can be separated with the knob realization of volume potentiometer by locking shifting block
Being connected together, then fixed by locking shifting block by the detent mechanism in housing, this is the most real
Show the locking function of volume potentiometer knob, its simple in construction, easy to operate, use
Under the automatism of family, the action such as friction will not rotate volume potentiometer knob, protects
User's ear-drum is without prejudice, and improves the safety in utilization of player.
Accompanying drawing explanation
Fig. 1 is this practicality new construction schematic diagram.
Detailed description of the invention
Embodiment: a kind of player volume potentiometer rotational lock mechanism, volume current potential
Device is fixed in player casing 1, and the knob 2 of volume potentiometer is exposed to housing 1
Outside, is provided with a locking shifting block 3 in housing 1, this locking shifting block 3 and volume potentiometer
Knob 2 can be connected together, described locking shifting block 3 be provided with one for regulation tune
Joint key 6, this adjusting key 6 is exposed to outside housing 1, and this adjusting key 6 can drive locking
Shifting block 3 engages with the knob 2 of volume potentiometer and separates, and is additionally provided with in described housing 1
One detent mechanism, this detent mechanism can fixing with locking shifting block 3 be connected, player
Volume adjusting is to after suitable size, by regulating key regulation locking shifting block 3 and volume
The knob 2 of potentiometer is fastened togather, and now the detent mechanism in housing 1 just and is locked
Shifting block 3 is fixed, and locking shifting block 3 cannot be slided in the case of without bigger External Force Acting
Dynamic, which achieves volume potentiometer knob 2 on a player by locked function,
Its simple in construction, easy to use, it is to avoid user is quilt in using earphone hearing process
Suddenly ear-drum is even stabbed in the sound shouting pain increased.
The knot that the knob 2 of described locking shifting block 3 and volume potentiometer can be connected together
Structure is: the knob 2 of volume potentiometer is coaxially connected with a gear 4, described locking shifting block
3 can linear slide be positioned in housing 1, and locking shifting block 3 is towards volume potentiometer one
Side is provided with tooth bar 5, and described tooth bar 5 can engage location with gear 4, when locking shifting block 3
Tooth bar 5 when departing from the gear 4 on the knob 2 of volume potentiometer, volume potentiometer
Knob 2 can arbitrarily regulate volume, when slide-and-lock shifting block 3 so that it is on
When tooth bar 5 engages with the gear 4 on knob 2, the knob 2 of volume potentiometer is the most engaged
Live, it is impossible to rotate again, it is achieved that locked function, except of course that outside this kind of structure also
Can be other structures: as the axle of volume potentiometer is provided with a circle pit, locking is dialled
Block 3 is provided with projection, and projection be able to be inserted in pit, also can realize above-mentioned card
Cooperation use, it addition, locking shifting block 3 can also rotate and be positioned in housing 1, locking is dialled
Block 3 is provided with can be with volume potentiometer knob 2 gear 4 meshed gears 4 mechanism
Engaging function can be realized too, this type of mechanism be all those skilled in the art according to
The similar means that this patent can it is readily conceivable that, belongs to the equivalent of this patent.
Described gear 4 is spur gear, and tooth bar 5 is helical rack.
Described locking shifting block 3 linear slide can be positioned the structure in housing 1 and be:
Locking shifting block 3 is provided with elongate holes, is provided with alignment pin, described location in housing 1
Pin is just inserted in described elongate holes, also or housing 1 is provided with strip hole, and lock
Tight shifting block 3 is provided with alignment pin, and this type of is all the equivalent of this patent.
Described regulating key is connected with locking shifting block 3, and described regulating key is dialled along locking
The depression being respectively provided on two sides with confession finger pressing of block 3 glide direction, it is simple to Yong Hucao
Make.
The structure that described detent mechanism can fixing with locking shifting block 3 be connected is: locking
Shifting block 3 is provided with at least one projection, is provided with at least one groove, institute in housing 1
State projection be able to be placed in this groove, when locking shifting block 3 moves to and volume current potential
During device knob 2 fastening state, the projection on locking shifting block 3 just slides into housing 1
In interior groove, now, without outside relatively noticeable effort, lock shifting block 3
On projection cannot spin off in the groove of housing 1, which achieves locking dial
The stationary positioned function of block 3, can also is that in housing 1 in one end width in addition to this structure
Degree is less than the mechanism of other end width, by locking shifting block 3 and housing 1 interference fit
Realizing location, this type of broadly falls into this patent protection domain.
