The present utility model realizes the rapid assembly and disassembly between the first connecting body 3 (speaker one) and the second connecting body 4 (speaker two) by setting the first connecting component 1 and the second connecting component 2. While greatly improving the installation efficiency, it also avoids the use of bolts and prolongs the service life of the connecting structure. After the first connecting body 3 (speaker one) and the second connecting body 4 (speaker two) are disassembled, it is convenient to carry the combined speakers, and each speaker can be used alone or in combination, meeting the different usage requirements of users. It should be noted that the first connecting component 1 and the second connecting component 2 of the present utility model are not only used for the rapid assembly and disassembly between combined speakers, but also can be used between other boxes that need to be assembled. It has a wide application range, low manufacturing cost, good economic benefits, and is worthy of wide promotion.

[0038] Specifically, in the solution of this embodiment, the second connection component 2 includes a second connection frame 21, a second connecting rod 22 and a pin shaft 23; a second mounting seat 24 is provided on the back of the second connection frame 21; a second through groove 25 for the second connecting rod 22 to rotate outwards is formed in the middle of the second connection frame 21; one end of the second connecting rod 22 is rotatably mounted on the second mounting seat 24 through the pin shaft 23; a clamping through hole 26 is provided at the other end of the second connecting rod 22; the second connecting rod 22 is locked in cooperation with the first connection component 1 through rotational movement.

[0039] Specifically, in the solution of this embodiment, the first connection component 1 includes a first connection frame 11, a first bolt 12, a pull rod 13 and a return spring 14; a first mounting seat 15 is provided at the bottom of the first connection frame 11; a first through groove 16 for the second connecting rod 22 to enter is formed in the middle of the first connection frame 11; locking seats 17 are symmetrically arranged below the first through groove 16; the pull rod 13 is reciprocally movably mounted on the first mounting seat 15; the return spring 14 is sleeved on the pull rod 13; the first bolt 12 is mounted on the insertion end of the pull rod 13; a locking through hole 18 for the first bolt 12 to insert is formed in the locking seat 17; when the second connecting rod 22 passes through the first through groove 16 and reaches between the locking seats 17, the first bolt 12 passes through the locking through hole 18 and is clamped on the clamping through hole 26. When the second connection body 4 (speaker two) needs to be assembled on the first connection body 3 (speaker one), first place the speaker two on the top of the speaker one and align it with the installation position. Then, manually pull the pull rod 13 to make the first bolt 12 leave the locking through hole 18. At this time, the return spring 14 is in a compressed state. Then, take out the second connecting rod 22 and rotate it downwards and outwards. During the rotation of the second connecting rod 22, it passes through the second through groove 25 and the first through groove 16 in sequence and enters the card slot formed by the two locking seats 17. At this time, the centers of the clamping through hole 26 and the locking through hole 18 are on the same axis. Then, manually release the pull rod 13, and the return spring 14 restores and generates an elastic force to push the first bolt 12 back to the initial position, so that the first bolt 12 passes through the locking through hole 18 and is clamped on the clamping through hole 26, realizing the locking of the second connecting rod 22, so that the second connection body 4 (speaker two) can be quickly assembled on the first connection body 3 (speaker one). The operation is simple and convenient, effectively improving the assembly efficiency. A person can easily assemble two speakers together and stack them for use without using tools, so as to improve the use effect of the speakers, increase the volume and enhance the atmosphere.

[0040] It should be noted that when the second connecting body 4 (speaker two) needs to be detached from the first connecting body 3 (speaker one), in the normal state, the first pin 12 is always in the card slot formed by the two locking seats 17. Manually pull the pull rod 13 to make the first pin 12 leave the clamping through hole 26 and the locking through hole 18, realizing the unlocking of the second connecting rod 22. At this time, the return spring 14 is in a compressed state. Then, take out the second connecting rod 22 from the card slot, and then manually release the pull rod 13. The return spring 14 restores and generates an elastic force to push the first pin 12 back to its initial position. The whole disassembly process is simple and convenient, effectively improving the disassembly efficiency. After the first connecting body 3 (speaker one) and the second connecting body 4 (speaker two) are disassembled, it is convenient to carry the combined speaker, and each speaker can be used alone or in combination, meeting the different usage requirements of users.

[0042] Specifically, in the solution of this embodiment, the head of the first pin 12 is conical. It should be noted that the head of the first pin 12 is made conical, so that the gap when it clamps the clamping through hole 26 of the second connecting rod 22 is smaller, thus making the connection between the two speakers firmer and ensuring the good operation of the device.

[0043] Specifically, in the solution of this embodiment, a handle 131 is provided at the pulling end of the pull rod 13. It should be noted that by providing the handle 131, it is convenient to operate the pull rod 13, effectively improving the assembly or disassembly efficiency of the second connecting body 4 (speaker two) and the first connecting body 3 (speaker one), with convenient operation and good user experience.

[0044] Specifically, in the solution of this embodiment, the first connecting component 1 further includes a connecting gasket 19; one end of the return spring 14 abuts against the first mounting seat 15 through the connecting gasket 19, and the other end abuts against the first pin 12 through the connecting gasket 19. It should be noted that by providing the connecting gasket 19, the stress area at the abutting part of the first pin 12 and the return spring 14 can be increased, ensuring that the return function of the return spring 14 can be realized normally.

[0045] Specifically, in the solution of this embodiment, a taking-out portion 221 protrudes from one end of the second connecting rod 22 close to the clamping through hole 26. It should be noted that by providing the taking-out portion 221, the second connecting rod 22 can be taken out well without using tools even if it is hidden in the speaker, further improving the assembly efficiency of the speaker.
