Description
Technical field
The present invention relates to black glue phonograph manufacturing field is belonged to, it is related to a kind of lift tone arm plate.
Background technology
Tone arm plate is the device that tone arm is fixed on black glue phonograph, and traditional tone arm plate is highly fixed, if changing different brands
Pickup or change the disc of different-thickness, the vertical angle that tracks of tone arm can change, so as to have influence on the sound of tone arm
Performance, the present invention provide a kind of liftable tone arm plate, can adjust the vertical of tone arm by disc thickness or different stylus
Track angle, is showed with obtaining optimal sound.
The content of the invention
To solve the defects of current tone arm plate, the invention provides a kind of lift tone arm plate.
The present invention adopts the following technical scheme that realization：
A kind of lift tone arm plate, including pedestal, the pedestal are a cylinder, and the outer wall of pedestal is provided with external screw thread,
The outer wall of pedestal is provided with the vertical guide groove perpendicular to base bottom surface；Adjustment ring is cased with pedestal, adjustment ring inwall is provided with
Internal thread corresponding with external screw thread；Upper cover plate is arranged with the top of pedestal, the bottom surface of upper cover plate props up the top surface of adjustment ring；Upper lid
The side wall of plate is provided with a limited screw, the vertical guide groove that limited screw is inserted on pedestal by the hole in upper cover plate side wall
In；Upper cover plate is provided with tone arm mounting hole；
Turn adjustment ring makes adjustment ring drive upper cover plate to move up and down, and limited screw prevents upper cover plate from being rotated with adjustment ring,
Needed for being moved in upper cover plate during position, the height of limited screw fixed cover plate is locked.
Further to improve, the outer wall of the adjustment ring is provided with annular knurl.
Further to improve, the external diameter of the adjustment ring is more than the external diameter of upper cover plate.
The beneficial effects of the invention are as follows：
Liftable tone arm plate in the present invention, can be freely lifted, and realize the scenic spot adjustment of tone arm height.Can be by singing
The vertical angle that tracks of piece thickness or different stylus adjustment tone arm, obtain optimal sound performance.
Brief description of the drawings
Fig. 1 is the profile of the present invention；
Fig. 2 is the top view of pedestal；
Fig. 3 is the top view of upper cover plate.
Embodiment
Below in conjunction with accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described.
A kind of lift tone arm plate as shown in Figure 1, including pedestal 1, the pedestal 1 are a cylinder, the outer wall of pedestal 1
External screw thread 2 is provided with, (top view of pedestal 1 is shown in figure to the outer wall of pedestal 1 provided with the vertical guide groove 3 perpendicular to the bottom surface of pedestal 1
2)；It is cased with adjustment ring 4 on pedestal 1, the inwall of adjustment ring 4 is provided with internal thread 5 corresponding with external screw thread 2, on the outer wall of adjustment ring 4
Provided with annular knurl, the external diameter of adjustment ring 4 is more than the external diameter of upper cover plate 6.The top of pedestal 1 is arranged with upper cover plate 6, the bottom of upper cover plate 6
Face props up the top surface of adjustment ring 4；The side wall of upper cover plate 6 is provided with a limited screw 8, and limited screw 8 passes through in the side wall of upper cover plate 6
Hole insertion pedestal 1 on vertical guide groove 3 in；Upper cover plate 6 is provided with tone arm mounting hole 7, and (top view of upper cover plate 6 is shown in figure
3)；
Pedestal 1 is fixed on black glue phonograph during use, and tone arm is installed on upper cover plate 6 by tone arm mounting hole 7.Adjusted in turn
The domain 4 makes adjustment ring 4 drive upper cover plate 6 to move up and down, and limited screw 8 is in relaxation state when mobile, upper cover plate 6 can more than
Under move freely, but due to the limitation of vertical guide groove 3, limited screw 8 can prevent upper cover plate 6 from being rotated with adjustment ring 4, when upper
When cover plate 6 is moved to required position, the height of the fixed cover plate 6 of limited screw 8 is locked.
Described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Based on the present invention
In embodiment, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, belongs to the scope of protection of the invention.
