Description
Technical Field
The utility model relates to the field of black rubber record players, in particular to a magnetic coupling.
Background
The gramophone is used for playing the vinyl record, and due to the characteristics of the vinyl record, slight disturbance of the gramophone can cause great influence on the played tone quality, and the gramophone is more and more precise along with the pursuit of music singers for continuously improving the music tone quality.
SUMMERY OF THE UTILITY MODEL
The application provides a magnetic coupling for a black rubber player.
The utility model is realized by adopting the following technical scheme:
a magnetic coupling comprises an upper connecting block and a lower connecting block, wherein an upper rotating shaft is connected above the upper connecting block, and a lower rotating shaft is connected below the lower connecting block;
the bottom of the upper connecting block is provided with an inserting block, and an upper connecting block magnet is fixed on the inserting block; the upper part of the lower connecting block is provided with a slot matched with the inserting block; the inserting block is inserted into the inserting slot; the lateral part of the upper connecting block magnet in the slot is provided with a lower connecting block magnet, the lower connecting block magnet and the upper connecting block magnet keep mutual exclusion, and the upper connecting block and the lower connecting block are not in contact.
Furthermore, the insertion block and the slot are in a straight line shape.
Furthermore, the left side and the right side of the upper rotating shaft on the inserting block are respectively provided with an upper connecting block magnet; and lower connecting block magnets are arranged on two sides of the upper connecting block magnets in the slots.
Compared with the prior art, the utility model has the following advantages:
the two parts of the coupling are respectively positioned on the driving disc shaft and the turntable shaft. The two parts are not in direct contact, but achieve the purpose of driving through the mutual exclusion principle of the magnets. The noise is reduced and the rotating speed is stabilized.

FIG. 2 is a top view of the upper connecting block;
fig. 3 is a top view of the lower connecting block.
Fig. 4 is a schematic view of the connection state.
Detailed Description
As shown in fig. 1-4, the magnetic coupling comprises an upper connecting block 1 and a lower connecting block 3, wherein the upper side of the upper connecting block 1 is connected with a turntable rotating shaft at the upper part, and the lower side of the lower connecting block 3 is connected with a driving disc rotating shaft at the lower part.
As shown in fig. 1, the bottom of the upper connecting block is an insert block, and the left and right sides of the upper rotating shaft on the insert block are respectively provided with an upper connecting block magnet 2. The upper part of the lower connecting block is provided with a slot matched with the inserting block; the insert is inserted into the slot 5. As shown in figure 3, the two sides of the upper connecting block magnet 2 in the slot are provided with lower connecting block magnets 4, the lower connecting block magnets and the upper connecting block magnets keep mutual exclusion, as shown in figure 4, a gap is formed between the upper connecting block and the lower connecting block, and the upper connecting block and the lower connecting block are interacted by virtue of repulsive force of the magnets and are not contacted.
The adoption of the non-contact coupling is beneficial to reducing noise and stabilizing the rotating speed. Is suitable for high-end black rubber record players.
