Rotary shaft structure for the turntable

The present invention relates to a rotating shaft structure for a turntable ring for a turntable, and particularly relates to a rotating shaft structure of a turntable with a shackle that can be easily assembled and adjusted to adjust the rotation of the shank.

According to the known main structure of the turntable, a turntable main seat, a turntable mounted on the main seat of the turntable and capable of being driven to rotate and placed for a vinyl record, and a reading machine for reading the vinyl The vocal arm of the music information of the record. The front end of the phono arm has a phono head, and a stylus is arranged in the phono head. The core object for dragging and reading the sound wave pattern in the record track, when the stylus is dragged and slid in the record track, The serrated track produces very fine vibrations, which in turn generate electromagnetic induction through the coils and magnets inside the cartridge, convert the sound ripples engraved in the track into sound electromagnetic signals, and finally let the amplifier amplify the electromagnetic sound signals to Can push the level of the horn to form the sound we can hear.

However, the process of moving the arm to the vinyl record requires assembly of a frame ring to achieve the function of swinging the arm up and down and moving left and right. The conventional assembly of the existing frame ring is as shown in the fourth to sixth figures. Shown as a bearing block (71) provided with a frame ring (7) and arranged in the frame ring (7), wherein bearings (72) are respectively embedded in the two corresponding sides of the bearing seat (71), and then The screws (73) are respectively locked to the bearing (72) via the two sides of the frame ring (7) to position the bearing seat (71) and allow the frame ring (7) to swing up and down and move left and right; As shown in the figure -6, the existing bearing and screw locks are in the state of implementation. As shown in the fourth figure, the end of the screw (73) has a stepped projection (731), and the stepped projection is used when locking. (731) Reaching the inner diameter of the bearing (72); or as shown in the fifth figure, using a one-side closed bearing (74), and then locking the pointed screw (75) into the inner diameter of the closed bearing (74) Or as shown in Figure 6 Transmissive bearing (72), and then pointed screws (75) lock into the corresponding bearing (72) inside diameter.

In summary, when the construction personnel assemble the locking screw to the bearing, if the lock is shallow, the bearing will have a left and right clearance in the bearing housing, causing the bearing to rotate and sound. Otherwise, if the locking is too deep The bearing is forced to lock in the bearing housing, which causes the bearing to rotate and the card is not smooth; and the above-mentioned locking processing will affect the function of the swinging arm swinging up and down and moving left and right. Therefore, the processing in this respect must rely on the experienced construction workers to fine-tune, which leads to the shortcomings of assembly and time-consuming labor.

The reason is that the creator has been adhering to the rich experience in design, development and actual production of the relevant industry for many years, and has been researched and improved again for practical use, providing a rotating shaft structure for the turntable of the turntable to achieve better practical value. The purpose of the person.
