[0014] Preferably, the sealing mechanism comprises a guide rack, the guide rack is fixedly installed on the inside of the waterproof support, the symmetrically arranged guide racks are connected with the guide tooth blocks on the outer wall of the turnover support, and the guide tooth blocks are used to drive the rotation of the turnover support.

[0015] Preferably, the sealing mechanism comprises lifting slide rods fixedly installed on the front and back sides inside the sealing waterproof cover, and the inner ends of the water removal wiper plates of the sealing mechanism are slidingly arranged inside the sealing waterproof cover, and the lifting slide rods slidingly penetrate the inner ends of the water removal wiper plates, and the lifting slide rods and the inner ends of the water removal wiper plates are connected by return springs.

[0016] Preferably, the water removal wiper plates of the sealing mechanism are initially arranged on the left side of the sealing waterproof cover, and after the sealing waterproof cover is lowered and rotated clockwise following the overturning support, the gravity of the water removal wiper plates on the front side of the sealing waterproof cover is greater than the elastic force of the return springs, so that the water removal wiper plates are lowered to the lower side of the sealing waterproof cover after rotation, and the sliding of the water removal wiper plates against the sealing waterproof cover realizes the cleaning of the rainwater on the surface of the sealing waterproof cover.

[0017] Preferably, the shielding mechanism comprises guide sliding grooves opened on the top of the waterproof support, and the shielding extension plates of the shielding mechanism are elastically slidingly arranged on the inside left and right sides of the guide sliding grooves, and the inner ends of the shielding extension plates in the initial state are connected to each other.

[0018] Preferably, the shielding mechanism comprises traction steel wires, the bottom ends of the traction steel wires are fixedly connected to the inner ends of the transmission sliding blocks on the front and back sides inside the waterproof support, the lifting of the transmission sliding blocks drives the traction steel wires to be tensioned and relaxed, and the top ends of the traction steel wires are bifurcatedly fixedly connected to the inner ends of the front and back sides of the shielding extension plates.

[0019] Preferably, the shielding mechanism comprises traction steel wires, the bottom ends of the traction steel wires are fixedly connected to the inner ends of the transmission sliding blocks on the front and back sides inside the waterproof support, the lifting of the transmission sliding blocks drives the traction steel wires to be tensioned and relaxed, and the top ends of the traction steel wires are bifurcatedly fixedly connected to the inner ends of the front and back sides of the shielding extension plates.

[0021] 1. The waterproof support suspends the sound box body, avoids the influence of outdoor accumulated water on the normal use of the sound box body, automatically performs Bluetooth search pairing after the power switch is turned on, and disperses audio by the sound emitting unit on the front side, and moves upward by the rotating bidirectional screw rod, the threaded positioning sliding block and the sound box body, so that the sound box body is close to the shielding mechanism, and the impact of dripping or oblique rainwater is reduced.

[0022] The two-way screw drives the transmission slider to descend with the turnover support and the sealing waterproof cover. The turnover support is engaged with the guide rack through the guide tooth block, thereby driving the turnover support and the sealing waterproof cover to rotate clockwise. The sealing waterproof cover is rotated from the horizontal state to the vertical state, which cooperates with the rising of the sound body to face the sound unit on the right side of the sound body.

[0023] 2. The magnetic attraction assembly above the right side of the sound body is adsorbed between the sealing waterproof cover, so that the sealing waterproof cover slides left along the direction of the guide slide rod inside the turnover support, and then the sealing waterproof cover is shielded on the sound unit on the front of the sound body to avoid the water inlet short circuit caused by the oblique rainwater washing.

[0024] 3. When the sealing waterproof cover rotates, the water removal scraper is heavier than the elasticity of the reset spring, so that the water removal scraper moves to the lowest position after the sealing waterproof cover rotates. After the sealing waterproof cover resets and rotates, the gravity is less than the elasticity of the reset spring, so that the water removal scraper achieves the effect of reciprocating sliding on the surface of the sealing waterproof cover, thereby cleaning the rainwater adhered to the front of the sealing waterproof cover.

[0025] 4. The transmission slider in the descending state drives the traction cable to be tensioned, and the shielding extension plate at the top end of the traction cable slides. After the outer end of the shielding extension plate extends outward, the shielding area of the waterproof support on the top of the sound body is increased, and the waterproof sealing effect of the sound body is further improved.
