The present invention is achieved by the following technical solutions:
A kind of disc machine sound arm anti-skid device, it is characterised in that: including sound arm fulcrum bearing, the sound arm fulcrum bearing is equipped with
For stationary tone arm and can relative to sound arm fulcrum bearing rotate sound arm shaft seat, the sound arm fulcrum bearing bottom is equipped with and sound
The coaxially connected reset push jack of arm shaft seat, the sound arm fulcrum bearing bottom are additionally provided with the anti-skidding bullet that can stop to reset push jack rotation
Spring, being equipped on the upper surface of the sound arm fulcrum bearing can be described anti-to the anti-skidding knob that the position of anti-slip spring is adjusted
Transmission device is equipped between sliding knob and anti-slip spring.
A kind of disc machine sound arm anti-skid device as described above, it is characterised in that: the transmission device includes and preventing sliding and rotating
Second gear button coaxially connected first gear and be fixedly connected with anti-slip spring, between the first gear and second gear
Be engaged with to be the third gear of the two transmission.
A kind of disc machine sound arm anti-skid device as described above, it is characterised in that: the second gear is located at sound arm shaft
Between seat and reset push jack, the second gear can be rotated coaxially with respect to sound arm shaft seat and reset push jack.
A kind of disc machine sound arm anti-skid device as described above, it is characterised in that: the upper surface of the second gear is located at
Its outer edge is equipped with the collar mounting holes seat of protrusion, and described anti-slip spring one end is threaded through in installation hole seat and will by glue
The two is fixed.
A kind of disc machine sound arm anti-skid device as described above, it is characterised in that: the reset push jack is equipped with push jack through-hole,
Described anti-slip spring one end is equipped with elastic arm that is protruding and being threaded through in push jack through-hole.
Compared with prior art, the present invention has the following advantages: when the movement of sound arm, resetting push jack can follow sound arm to rotate,
When sound arm turns to certain position, resetting push jack can be contacted in some position with anti-slip spring, and anti-slip spring is resetting
Flexible deformation is under the action of push jack to the elastic force to reset push jack one opposite direction of generation, when the rotation of this elastic force and sound arm
When power is identical, sound arm then keeps balance to no longer rotate in this position.And user can be changed by rotation grip knob it is anti-
Therefore the position of sliding spring can set sound arm by rotation grip knob and turn to some position and no longer rotate, thus
Have the function of to repeat playing.
[Detailed description of the invention]
Specific embodiments of the present invention will be described in further detail with reference to the accompanying drawing, in which:
Fig. 1 is a kind of structural schematic diagram of disc machine sound arm anti-skid device of the present invention；
Fig. 2 is a kind of main view of disc machine sound arm anti-skid device of the present invention；
Fig. 3 is in Fig. 2 along the Section View in the direction I-I.
[specific embodiment]
The invention will be further described below in conjunction with the accompanying drawings:
A kind of disc machine sound arm anti-skid device as shown in Figure 1 to Figure 3, including sound arm fulcrum bearing 1, the sound arm fulcrum bearing
1 is equipped with the sound arm shaft seat 3 that is used for stationary tone arm 2 and can rotate relative to sound arm fulcrum bearing 1, the sound arm fulcrum bearing 1
Bottom is equipped with the reset push jack 4 coaxially connected with sound arm shaft seat 3, and 1 bottom of sound arm fulcrum bearing, which is additionally provided with, can stop to reset
The anti-slip spring 5 that push jack 4 rotates, the position of anti-slip spring 5 can be adjusted by being equipped on the upper surface of the sound arm fulcrum bearing 1
The anti-skidding knob 6 of section is equipped with transmission device 7 between the anti-skidding knob 6 and anti-slip spring 5.When sound arm 2 moves, reset is pushed away
Piece 4 can follow sound arm 2 to rotate, and when sound arm 2 turns to certain position, resetting push jack 4 can be in some position and anti-skidding bullet
Spring 5 contact, anti-slip spring 5 under the action of resetting push jack 4 flexible deformation to reset push jack 4 generation one opposite direction bullet
Power can make sound arm 2 keep balance to no longer rotate in some position when this elastic force is identical as the rotatory force of sound arm 2.Pass through
Therefore rotation grip knob 6, the position that can change anti-slip spring 5 under the effect of transmission device 7 can pass through rotation grip
Knob 6 turns to some position setting sound arm 2 and no longer rotates.
The transmission device 7 includes the first gear 71 coaxially connected with anti-skidding knob 6 and is fixedly connected with anti-slip spring 5
Second gear 72, be engaged between the first gear 71 and second gear 72 can for both transmission third gear 73,
The first gear 71, third gear 73 and second gear 72 are successively ascending, engage deceleration transmission by multi-stage gear, make
The position adjusting for obtaining anti-slip spring 5 is more accurate.
The second gear 72 is located at sound arm shaft seat 3 and resets between push jack 4, and the second gear 72 can be with respect to sound
Arm shaft seat 3 and reset push jack 4 rotate coaxially, and such structure design can also reduce difference zero under the premise of assurance function
Part optimizes space layout to the occupancy in space, simplifies structure.
The upper surface of the second gear 72 is located at the collar mounting holes seat 721 that its outer edge is equipped with protrusion, described anti-
Sliding 5 one end of spring is threaded through in installation hole seat 721 and is fixed the two by glue, and structure is simple, and anti-slip spring 5 is easy to more
It changes.
