It is typically designed to be easy to connect to the wall, offering advantages such as space saving and ease of maintenance.

[0003] Existing wall-mounted trunk amplifiers are often fixed to the wall by drilling holes and using bolts. However, this method requires repeated bolt removal when the trunk amplifier needs to be disassembled or maintained, making the maintenance or disassembly process very cumbersome. Furthermore, trunk amplifiers installed at high locations usually require climbing tools for disassembly or maintenance, thus increasing the safety and convenience of user maintenance.

[0004] Therefore, to address the problems of existing wall-mounted trunk amplifiers being inconvenient for users to install on the wall and being cumbersome to disassemble or maintain, a wall-mounted trunk amplifier that is easy to connect to the wall is developed. By adding a lifting structure and a limiting frame installation structure to the wall-mounted trunk amplifier, the convenience and stability of installing the trunk amplifier on the wall can be effectively improved, and it can also facilitate users to maintain the trunk amplifier at a high position.

The trunk amplifier body 5 is set on the inner wall of the fixing frame 2. The upper and lower ends of the trunk amplifier body 5 are fixedly connected to the connecting panels 17. The four corner edges of the front end of the trunk amplifier body 5 are provided with grooves 22. The protective shell 3 is fitted onto the outer wall of the positioning buckle 13. A second notch 18 is opened at the rear edge of the protective shell 3. The screw groove 12 is adapted to the lead screw 6. The outer wall of the lifting platform 4 is in contact with the inner wall of the wall frame 1. The inner wall of the positioning buckle 13 is in contact with the outer wall at the four corner edges of the trunk amplifier body 5. The protrusion 15 is adapted to the groove 22.

[0025] The servo motor 10 drives the lead screw 6 to adjust the lifting platform 4, thereby driving the trunk amplifier body 5 installed in the fixed frame 2 to descend from a high position to a low position, so that the user can maintain or install the trunk amplifier body 5. The four sets of positioning buckles 13 can clamp and limit the outer wall at the four corners of the trunk amplifier body 5. With the help of the protrusions 15 and the grooves 22, the stability of the positioning buckles 13 in limiting and fixing the trunk amplifier body 5 can be further improved, so that the user can firmly install the trunk amplifier body 5 in the fixed frame 2, and at the same time, the user can easily remove the trunk amplifier body 5 from the fixed frame 2.

[0026] Please see Figures 3-4 In this embodiment, the inner wall of the wall frame 1 is fixed with symmetrically distributed guide rails 8. The guide rails 8 are located on the left and right sides of the lead screw 6. In use, the guide rails 8 can help improve the stability of the lifting platform 4 when it moves up and down along the inner wall of the wall frame 1. The upper and lower ends of the lifting platform 4 are provided with sliding grooves 11. The sliding grooves 11 are located on the left and right sides of the screw groove 12.

The four corner edges of the wall frame 1 are fixed with feet 7. In use, the motor protective shell 9 can protect the servo motor 10 to improve its service life.

[0027] Please see Figures 4-6In this embodiment, the front end of the protective shell 3 is provided with a first groove 20, and a dustproof mesh plate 19 is installed in the first groove 20. When in use, the dustproof mesh plate 19 can prevent external dust from adsorbing on the surface of the trunk amplifier body 5 and affecting its normal use.

[0030] Next, the protective shell 3 is removed from the outer wall of the positioning bracket 13, and the trunk amplifier body 5 is pressed into the positioning bracket 13. The positioning bracket 13 deforms to fit the four corner edges of the trunk amplifier body 5. Then, the protrusion 15 is installed into the groove 22 to install the trunk amplifier body 5 onto the fixing bracket 2. Finally, the protective shell 3 is put onto the positioning bracket 13 and covers the trunk amplifier body 5.

[0031] Then, restart the servo motor 10 to drive the lead screw 6 to lower the lifting platform 4, the fixed frame 2 and the trunk amplifier body 5 to the inner wall of the uppermost end of the wall frame 1 for reset;

[0032] When maintenance of the trunk amplifier body 5 is required, as described above, the servo motor 10 drives the lead screw 6 to lower the lifting platform 4, the fixing frame 2 and the trunk amplifier body 5 to the inner wall of the lowest end of the wall frame 1, and then the protective shell 3 is removed to maintain the trunk amplifier body 5.

[0033] Through the above steps, the servo motor 10 can drive the lead screw 6 to adjust the lifting platform 4, thereby driving the trunk amplifier body 5 installed in the fixed frame 2 to descend from a high position to a low position, so that the user can maintain or install the trunk amplifier body 5. The four sets of positioning buckles 13 can clamp and limit the outer wall at the four corners of the trunk amplifier body 5. With the cooperation of the protrusions 15 and the grooves 22, the stability of the positioning buckles 13 in limiting and fixing the trunk amplifier body 5 can be further improved, so that the user can firmly install the trunk amplifier body 5 in the fixed frame 2, and at the same time, the user can easily remove the trunk amplifier body 5 from the fixed frame 2. This solves the problem that the existing wall-mounted trunk amplifier is inconvenient for users to install on the wall and is also cumbersome to maintain.
