In order to ensure the safety of children, parents swipe their cards at the door when picking up and dropping off children, especially at school and after school time. At the same time, in order to make the pick-up and drop-off of kindergarten more orderly, teachers also need to play music non-stop to welcome or see off children. Sometimes teachers also need to inform parents of some notices. All of these require kindergarten teachers to keep shouting and playing operations, etc., which seriously increases the workload of kindergarten teachers.

[0003] Most of the broadcasting machines are installed in kindergartens in a fixed manner. When the broadcasting machine fails, it is not convenient to remove the shell of the broadcasting machine and perform internal maintenance on the broadcasting machine, which reduces the efficiency of disassembly and maintenance of the broadcasting machine after it is damaged.

[0030] The shift broadcasting machine has the advantage of being easy to maintain. When the internal part of the shift broadcasting machine is damaged, the housing needs to be removed from the mounting plate by using a disassembly assembly: the maintenance personnel pull the pull rod toward the middle part at the same time by hand, and the pull rod drives the limit blocks to approach each other and compress the spring 1. At this time, the limit blocks are separated from the through hole on the limit frame. The maintenance personnel hold the housing and lift it upward. The protrusions on both sides of the housing slide upward from the frame, and the limit frame exits the installation frame. At this time, the housing can be removed, which is convenient for inspecting the components inside the housing. After the maintenance is completed, the two protrusions are aligned with the through grooves of the frame, the housing is slid downward, and the pull rod is pushed inward at the same time. The pull rod drives the limit blocks to approach each other, and the housing continues to move downward until the limit frame at the bottom of the housing enters the installation frame. The two pull rods are released, and the spring 1 uses the elastic force to drag the limit blocks to the through hole in the limit frame, completing the installation connection between the housing and the installation frame, solving the problem that the existing shift broadcasting machine is not easy to quickly disassemble the housing after damage, thereby reducing the maintenance efficiency.

[0039] 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.

[0040] Embodiment 1

[0041] See also Figure 1-5 A maintenance-friendly broadcasting machine includes a main assembly 1, the main assembly 1 includes: a mounting plate 11, a frame 12 is symmetrically arranged on the front side of the mounting plate 11; a housing 13, movably connected to the front side wall of the mounting plate 11; protrusions 14, symmetrically arranged on both sides of the housing 13, the protrusions 14 are slidably connected to the frame 12; a mounting frame 15, arranged on the front side wall of the mounting plate 11; a disassembly assembly 2 is arranged on the mounting frame 15 and the housing 13, the disassembly assembly 2 includes: a bottom plate 21, arranged on The installation frame 15 has an internal cavity; a spring 22 is symmetrically arranged on the outer side wall of the bottom plate 21; a limit block 23 is fixedly connected to the end of the spring 22 away from the bottom plate 21; a pull rod 24 is arranged on the front side wall of the limit block 23, and a through slot for the pull rod 24 to move is provided on the front side of the installation frame 15; a limit frame 25 is symmetrically arranged on the bottom of the shell 13, a through hole is provided on the limit frame 25, and a through slot for the limit frame 25 to move is provided on the top of the installation frame 15. The through hole provided on the limit frame 25 is equal in size to the limit block 23. A telescopic rod 221 is fixedly connected between the bottom plate 21 and the limit block 23, and the spring 22 is sleeved on the outside of the telescopic rod 221.

[0042] When in use, the mounting plate 11 is mounted on the wall. When damage occurs inside the broadcasting machine, the housing 13 needs to be removed from the mounting plate 11 for easy inspection of the interior. At this time, the disassembly assembly 2 is used for disassembly: the maintenance personnel pulls the pull rod 24 toward the middle at the same time by hand, and the pull rod 24 drives the limit blocks 23 to approach each other and compress the spring 22. At this time, the limit blocks 23 are disengaged from the through holes on the limit frame 25. The maintenance personnel holds the housing 13 and lifts it up. The protrusions 14 on both sides of the housing 13 slide upward from the frame 12, and the limit frame 25 withdraws from the installation frame 15. At this time, the housing 13 can be removed for easy inspection of the components inside the housing 13. After the repair is completed, align the two protrusions 14 with the through slots of the frame 12, slide the shell 13 downward, and the shell 13 gradually covers the front side of the mounting plate 11. When the shell 13 slides to the bottom, push the pull rod 24 inward at the same time, and the pull rod 24 drives the limit block 23 to move closer to each other, and continue to move the shell 13 downward until the limit frame 25 at the bottom of the shell 13 enters the inside of the mounting frame 15, release the two pull rods 24, and the spring 1 22 drags the limit block 23 to the through hole in the limit frame 25 with the help of elastic force, completing the installation connection between the shell 13 and the mounting frame 15. The through hole on the limit frame 25 is the same size as the limit block 23, so that when the limit block 23 enters the through hole in the limit frame 25, it prevents the shell 13 and the mounting frame 15 from shaking after installation, affecting the stability of the shell 13 after being fixed. The telescopic rod 221 guides the extension and retraction of the spring 1 22 to prevent the spring 1 22 from being skewed when being driven by the limit block 23 to extend and retract, which affects the limit block 23 from quickly entering the through hole of the limit frame 25 to complete the installation of the housing 13.

[0043] Embodiment 2

[0044] On the basis of the first embodiment, an auxiliary function is added.

[0045] See also Figure 1-5 The installation frame 15 is provided with a linkage mechanism 26, which includes: a push block 261, symmetrically arranged in the internal cavity of the installation frame 15; a slider 262, arranged at the top of the push block 261, slidably connected to the installation frame 15, and a slide groove for the slider 262 to slide is arranged inside the installation frame 15; a spring 263, the top of which is fixedly connected to the bottom of the installation frame 15; a push plate 264, fixedly connected to the bottom of the spring 263; a push rod 265, symmetrically fixedly connected to the top of the push plate 264, the push rod 265 extends to the inside of the installation frame 15, and the spring 263 is sleeved on the outside of the push rod 265. The top surface of the limit block 23 is an inclined surface. The outer wall of the housing 13 is symmetrically provided with a handle 16.

[0046] The linkage mechanism 26 can realize the simultaneous movement of the two pull rods 24: when the shell 13 needs to be disassembled, the maintenance personnel presses the push plate 264 upwards, and the push plate 264 drives the push rod 265 to extend into the interior of the installation frame 15, and the push rod 265 extends inward to move the two push blocks 261 toward the middle at the same time along the inclined surface of the push block 261. At this time, the slider 262 moves in the slide groove, and the push block 261 squeezes the two pull rods 24 toward the middle at the same time. By realizing one action, the two limit blocks 23 can be simultaneously withdrawn from the through hole of the limit frame 25, which improves the convenience of operation. After the push plate 264 is used, the spring 263 drives the push plate 264 back to its original position, and the elastic force of the spring 1 22 drives the limit block 23, the pull rod 24 and the push block 261 back to their original positions. The inclined surface at the top of the limit block 23 allows the bottom of the limit frame 25 to move downward on the inclined surface at the top of the limit block 23 during the process of gradually extending the limit frame 25 into the interior of the installation frame 15 when installing the housing 13, and the two limit blocks 23 are pressed inward at the same time until the through hole of the limit frame 25 moves downward to the position of the limit block 23, and the spring 1 22 pushes the limit block 23 into the through hole with the help of elastic force, so that the housing 13 can be installed without operating the pull rod 24 and the push plate 264, thereby improving the installation efficiency. The handle 16 is convenient for maintenance personnel to hold and remove and install the housing 13.
