Detailed description of the invention
Below in conjunction with accompanying drawing, the technical scheme in this utility model embodiment is clearly and completely described.
A kind of lift tone arm plate as shown in Figure 1, including pedestal 1, described pedestal 1 is a cylinder, and the outer wall of pedestal 1 is provided with external screw thread 2, and the outer wall of pedestal 1 is provided with the top view of the vertical guide groove 3(pedestal 1 being perpendicular to pedestal 1 bottom surface and sees Fig. 2)；Being cased with adjustment ring 4 on pedestal 1, adjustment ring 4 inwall is provided with the female thread 5 corresponding with external screw thread 2, and the outer wall of adjustment ring 4 is provided with annular knurl, and 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, and the bottom surface of upper cover plate 6 props up the end face of adjustment ring 4；The sidewall of upper cover plate 6 is provided with a limited screw 8, and limited screw 8 is inserted in the vertical guide groove 3 on pedestal 1 by the hole on upper cover plate 6 sidewall；Upper cover plate 6 is provided with the top view of tone arm installing hole 7(upper cover plate 6 and sees Fig. 3)；
During use, pedestal 1 is fixed on black glue phonograph, and tone arm is installed on cover plate 6 by tone arm installing hole 7.Adjustment ring 4 is made to drive upper cover plate 6 to move up and down in turn adjustment ring 4, limited screw 8 is in relaxation state when mobile, upper cover plate 6 can freely up and down move, but the restriction due to vertical guide groove 3, limited screw 8 is possible to prevent upper cover plate 6 to rotate with adjustment ring 4, when upper cover plate 6 moves to desired location, the height of locking limited screw 8 fixed cover plate 6.
Described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
