[0021] The utility model is specifically introduced below in connection with the drawing and concrete embodiment.

[0022] Embodiment: a kind of loudspeaker installation is used quick connection structure, such as Figures 1-5As shown, including the horn body 1, connecting shell 2, shell 3, mounting block 31, ball 4, spring 5, block 6, reinforcing frame 7, push block 8, card frame 9, spring 10, inclined block 11, clamping block 12 and rubber pad 13, the outer side of the horn body 1 is connected with the connecting shell 2, four L-shaped limiting grooves are arranged on the outer side of the connecting shell 2, one block 6 is connected in each limiting groove, the shell 3 is embeddedly arranged outside the connecting shell 2, the rear side of the connecting shell 2 is provided with a magnet, the connecting shell 2 and the shell 3 are magnetically connected, so that the connecting shell 2 and the shell 3 are stably connected, the left and right sides of the shell 3 are connected with the mounting block 31, which is used to provide additional mounting point, so as to fix the whole structure in the required position, square grooves are evenly arranged on the inner side of the shell 3 along the circumference, spring 5 is connected to the inner side wall of the square groove of the shell 3, the other end of the spring 5 is connected with the ball 4, the ball 4 is connected with the adjacent block 6, the quick connection between the connecting shell 2 and the shell 3 is realized, the two sides of the block 6 are designed as inclined surface, so as to be connected with the ball 4 and released, the reinforcing frame 7 is connected with the push block 8 at the center position of the left and right sides of the reinforcing frame 7, the card frame 9 is slidably connected to the left and right sides of the shell 3, the clamping block 12 is connected to the end of the card frame 9 close to each other, the spring 10 is connected between the clamping block 12 and the card frame 9, the spring 10 is sleeved on the card frame 9, the spring 10 provides elastic force for the clamping block 12, so as to tightly clamp the horn body 1 when the clamping block 12 is not subjected to external force, the inclined block 11 is connected to the end of the card frame 9 away from each other, the rear end of the push block 8 is designed as arc surface, when the reinforcing frame 7 is pushed backward, the push block 8 can contact with the inclined block 11 and push, so as to drive the card frame 9 and the clamping block 12 to move outward, the spring 10 is compressed under stress, so that the horn body 1 is not clamped, the rubber pad 13 is connected to the inner side of the clamping block 12, which plays a role of anti-skid for the connecting shell 2.

[0023] When the quick connection structure for horn installation is needed, the operation steps are as follows: first, align the connecting shell 2 with the opening of the shell 3, and push it smoothly backward. As the connecting shell 2 gradually penetrates into the shell 3, when the connecting shell 2 is pushed to the designed limit position, the next step is to rotate. Because the two sides of the block 6 are ingeniously designed as inclined surface, when the connecting shell 2 continues to rotate, the inclined surface of the block 6 will gradually contact with the ball 4 inside the shell 3. At this time, the ball 4 will be extruded along the direction of the inclined surface of the block 6, and the spring 5 will be compressed and store energy.

[0024] When the connecting shell 2 is turned to the predetermined limit position, the contact between the inclined surface of the clamping block 6 and the clamping ball 4 reaches the maximum point and then gradually separates. At this time, the spring 5 pushes the clamping ball 4 out rapidly under the action of the restoring force, so that the clamping ball 4 forms a stable clamping with the other side of the clamping block 6. In this way, the connecting shell 2 is firmly and reliably fixed inside the shell 3, and the entire installation process is quick and simple.

[0025] When it is necessary to disassemble the loudspeaker for replacement or repair, the operation is also simple. Only need to push the reinforcing frame 7 backward, so that the arc surface of the pushing block 8 contacts with the inclined block 11 and generates a pushing action. Since the inclined block 11 is closely connected with the clamping frame 9, the pushing force of the pushing block 8 will make the clamping frame 9 slide outward along the track inside the shell 3 and drive the clamping block 12 to move outward. At this time, the spring 10 is compressed and stores energy.

[0026] With the outward movement of the clamping block 12, the loudspeaker body 1 is no longer subjected to the clamping action, so that it can be conveniently taken out from the installation structure for replacement or repair. After the disassembly is completed, the pushing force on the reinforcing frame 7 is released, and the spring 10 pushes the clamping block 12 back to the original position under the action of the restoring force, ready for the next installation.

[0027] Although the embodiments of the utility model have been shown and described, it can be understood by those of ordinary skill in the art that changes can be made to these embodiments without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
