[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 3 , the utility model provides a technical solution:

[0021] A sound support frame comprises a support base 1 with a storage cavity inside, a sealing cover plate 2 movably installed above the storage cavity, a lifting seat 3 arranged inside the support base 1 and a limiting mechanism installed on the lifting seat 3 for fixing the sound, a lifting cavity is opened inside the side wall of the support base 1, a rotating shaft 4 and a slider 5 sleeved on the outside of the rotating shaft 4 are installed inside the lifting cavity, one end of the rotating shaft 4 is connected to the output end of a motor 6 installed below the lifting cavity, a thread groove connected to the slider 5 in a spiral transmission is provided on the outside of the rotating shaft 4, the slider 5 is connected to the lifting seat 3 through a sliding rod, a gear 7 is installed on the outside of the upper end of the rotating shaft 4, a rack 8 is meshed on one side of the gear 7, a cavity is opened on the side wall of the support base 1, a limiting block matching one end of the sealing cover plate 2 is provided inside the cavity, and the rack 8 is installed on the side wall of the limiting block.

[0022] When in use, the motor 6 can be driven to drive the rotating shaft 4 to rotate. On the one hand, the slider 5 can be moved along the threaded groove on the rotating shaft 4, thereby driving the lifting seat 3 to lift and lower. On the other hand, the rotation of the rotating shaft 4 drives the gear 7 to rotate, and the gear 7 drives the rack 8 to move, thereby driving the limit block to move into the cavity, releasing the limit on the sealing cover plate 2, so that when the lifting seat 3 moves and lifts, it can resist the sealing cover plate 2 and rotate upward to open, so that the lifting seat 3 moves to the outside of the supporting base 1, and the speaker is clamped and fixed on the supporting base 1 through the limiting mechanism, completing the support and fixation of the speaker to prevent it from falling, and can also adjust the height of the speaker within a certain range. At the same time, the speaker can be left in place after use, so that the speaker can follow the lifting seat 3 to move to the supporting base 1 for storage.

[0023] The limiting mechanism includes a two-way threaded rod 9 installed inside the lifting seat 3 and a movable block 10 symmetrically sleeved on the outside of the two-way threaded rod 9 and connected to the two-way threaded rod 9 with a spiral transmission. A clamping plate 11 is provided on one side of the movable block 10. One end of the two-way threaded rod 9 passes through the outside of the lifting seat 3 and an adjusting knob is provided. When fixing the speaker, the speaker can be placed between the two clamping plates 11, and the adjusting knob is manually turned to move the clamping plate 11 toward the direction of the speaker and clamp it.

[0024] The limit block adopts a "concave" structure. When the sealing cover plate 2 is rotated downward to close, the rotating shaft 4 rotates in the opposite direction, driving the limit block to move toward the sealing cover plate 2 to limit it and play a role in dust prevention.

[0025] An electric control switch 12 connected to the motor 6 is installed on the top of the support base 1. When in use, the motor 6 adopts a forward and reverse motor, and its forward and reverse rotation can be controlled by the electric control switch 12.

[0026] The side walls of the lifting chamber and the bottom wall of the storage chamber are both installed with rubber pads to prevent the rack 8 and the lifting seat 3 from directly hitting the inner walls of the lifting chamber and the storage chamber when moving. The rubber pads play a role of buffering protection.

[0027] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection.
