Detailed Description

The technical solution of the present invention will be further described in detail with reference to the drawings attached to the specification, but the present invention is not limited thereto.

As shown in fig. 1 to 4, the dipole sound insulator pup joint connecting mechanism comprises a connecting base block and a central block 2, wherein the connecting base block comprises a first connecting base block 1 and a second connecting base block 3 which are identical in structure. The connection base block is as shown in fig. 2, including base block body 5 and the last boss 6 and the lower boss 7 of base block body 5 body coupling, base block body 5 is cylindrical and is equipped with cylinder hole 8, goes up boss 6 and lower boss 7 and is two, and axial symmetry, it all sets up logical groove to go up boss 6 and lower boss 7 and become vertical distribution and internal surface in the circumferencial direction, is last logical groove 9 and lower logical groove 10 respectively, is equipped with logical groove pinhole 17 and the retaining ring groove 11 for the hole that link up in the central direction that leads to the groove.

The center block 2 is a square block with a center through hole 14, four bosses 12 are arranged on four circumferential surfaces of the square block, the four bosses 12 are symmetrical relative to the center of the square block, four boss pin holes 13 which are not communicated and four through round holes 15 with the diameter smaller than that of the pin holes are arranged at the centers of the four bosses 12, and a step surface 16 is formed between the through round holes 15 and the boss pin holes 13. The central through hole 14 and the cylindrical inner hole 8 are both provided with leather bags, so that the inside of the instrument can be conveniently arranged through wires.

The center block 2 is coupled to the lower bosses 7 of the first connection base block 1, the lower through grooves 10 of the lower bosses 7 are matched with the bosses 12 of the center block 2, and the bosses 12 of the center block 2 are inserted between the lower bosses 7 of the first connection base block 1 in the direction of the lower through grooves 10 of the first connection base block 1. Correspondingly, the central block 2 is connected with the upper through groove 6 of the second connection base block 3, the upper through groove 9 of the upper through groove 6 is matched with the boss 12 of the central block 2, and the bosses 12 on the other two sides of the central block 2 can be embedded between the second connection base blocks 3 along the direction of the upper through groove 9 of the second connection base block 3. The through groove pin holes 17 formed in the first connection base block 1 and the second connection base block 3 correspond to the boss pin holes 13 of the center block 2, the cylindrical pins 11 are mounted in the through groove pin holes 17 and the boss pin holes 13 of the first connection base block 1, the second connection base block 3 and the center block 2, which are opposite to each other, and in order to fix the cylindrical pins 11 and prevent the cylindrical pins 11 from falling off from the pin holes of the center block 2 and the connection base blocks, the outer sides of the cylindrical pins 3 are provided with hole retaining rings 4.

The width height of the boss 12 of the central block 2 is slightly smaller than that of the through groove arranged on the connecting base block, so that the central block 2 is embedded into the connecting base block to limit the movement of the connecting base block in the axial direction. The pin holes of the two are opposite after the central block 2 is embedded into the connecting base block, so that the cylindrical pin 11 can be installed to limit the connecting base block from sliding out along the direction of the through groove.

The clearance between the cylindrical pin 11 and the boss pin hole 13 and the through groove pin hole 17 is larger than the clearance between the boss 12 of the center block 2 and the through groove of the connecting base block, so that the force mainly acts between the boss 12 of the center block 2 and the through groove of the connecting base block in the two states of pressing and pulling, and the force born by the cylindrical pin 11 is small enough to be ignored.

As shown in fig. 5, the second connection base block 3 and the first connection base block 1 may be connected to the center block 2 at both ends thereof in the same manner as shown in fig. 1, depending on the length requirement.
