DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1-Figure 5 As shown, a speaker that is easy to install includes a speaker 1 and a fixing device 2; the fixing device 2 is installed with a first fixing shell 21, a movable groove 22 is opened on one side of the first fixing shell 21, a bevel gear 23 is movably installed on the inner wall of the movable groove 22, a knob 24 is fixedly installed on the top of the bevel gear 23, one side of the bevel gear 23 is drivingly connected to a gear turntable 25, and the other side of the gear turntable 25 is opened with a threaded ring 31;

[0024] During operation, a person rotates the knob 24, and the knob 24 links the bevel gear 23 to rotate to transmit the gear turntable 25 on one side, which is convenient for installation and disassembly.

[0025] Furthermore, the speaker 1 is provided with a main body 11, a cone 12 is fixedly installed on one side of the main body 11, a fixing frame 13 is fixedly installed around the cone 12, one side of the fixing frame 13 is fixedly installed with the main body 11, and a first fixing shell 21 is fixedly installed on one side of the back of the main body 11;

[0026] During operation, the installation of the fixing bracket 13 is helpful to strengthen the body strength of the loudspeaker 1, and provide corresponding protection for the main body 11 and the cone 12 to prevent the internal components from being damaged by external forces.

[0027] Furthermore, a second fixed shell 26 is fixedly installed on one side of the first fixed shell 21, and a gear rotating disk 25 is movably installed between the second fixed shell 26 and the first fixed shell 21;

[0028] During operation, the gear turntable 25 is limited by the first fixed housing 21 and the second fixed housing 26 to ensure that the gear turntable 25 performs stable rotational motion to achieve transmission.

[0029] Furthermore, the second fixed shell 26 is provided with three sliding grooves 32, and one side of the three sliding grooves 32 is movably mounted with a limit head 33, and one side of the three limit heads 33 is provided with a latching tooth 34, and one side of the latching tooth 34 is threadedly connected with a thread ring 31;

[0030] During operation, when the gear turntable 25 rotates, the threaded ring 31 on the back cooperates with the latching teeth 34 to transmit the limit head 33 , so that the limit head 33 moves correspondingly inside the sliding groove 32 .

[0031] Furthermore, a mounting plate 27 is movably mounted on one side of the second fixed shell 26, a mounting groove 28 is formed on one side of the mounting plate 27, and three limit heads 33 are clamped on the inner wall of the mounting groove 28;

[0032] During operation, the limiting head 33 is extended and retracted on the second fixing shell 26 to cooperate with the mounting groove 28 on the mounting plate 27 to achieve snap connection, and the entire body is limited on the mounting plate 27 through snap connection to achieve installation and fixation.

[0033] Furthermore, the mounting plate 27 is provided with four thread grooves 29;

[0034] During operation, the threaded grooves 29 are opened and the mounting plate 27 is fixed with bolts, so that the whole is strongly supported, which is beneficial to the bearing and stability of the whole.

[0035] Working principle: during installation, one side of the second fixed shell 26 is placed inside the mounting groove 28 provided in the mounting plate 27. At this time, the personnel rotates the knob 24, so that the knob 24 drives the gear turntable 25 to rotate counterclockwise through the bevel gear 23 fixed at the bottom. At the same time, the threaded ring 31 on one side of the gear turntable 25 and the locking teeth 34 provided in the limit head 33 are transmitted in a threaded matching manner. The limit head 33 is limited by the sliding groove 32 provided in the second fixed shell 26 when it is active. Therefore, when the gear turntable 25 rotates, the rotational movement of the gear turntable 25 is converted into linear movement of the limit head 33 inside the sliding groove 32 through cooperation. The limit head 33 is expanded outward to complete the clamping and limiting with the mounting groove 28 provided in the mounting plate 27, so as to achieve the overall fixation. Similarly, when disassembly is required, the limit head 33 is retracted on the second fixed shell 26 to cancel the clamping of the mounting groove 28, so that the overall can be quickly disassembled without being clamped and limited.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
