[0025] Under normal conditions, the protective cover 2 will cause the first connecting plates 10 on both sides to compress the first spring 12, resulting in elastic deformation within a tolerable range. The second slide groove 8 in the limit block 7 will lock the second movable ball 9. In case of emergency, the public can push the second movable ball 9 outward with external force, so that the second movable ball 9 can slide out of the second slide groove 8 smoothly. At the same time, the second movable ball 9 will drive the connecting rod 5 to slide outward in the first slide groove 6, and then drive the first movable ball 4 to move inside the fixed block 3. At this time, the second movable ball 9 is unlocked, and due to the elasticity of the first spring 12, the first connecting plate 10 is instantly pushed open by the outward force, and the protective cover 2 is also pushed open at the same time.

[0026] By pushing the second movable ball 9 outward with external force, the second movable ball 9 smoothly slides out of the second slide groove 8. At the same time, the second movable ball 9 drives the connecting rod 5 to slide outward in the first slide groove 6, and then also drives the first movable ball 4 to move inside the fixed block 3. At this time, the second movable ball 9 is unlocked, and due to the elasticity of the first spring 12, the first connecting plate 10 is instantly popped open by the outward force. At the same time, the protective cover 2 is also popped open. Compared with traditional devices, this device allows rescue forces to respond more quickly, reduces potential injuries and losses, and makes it easier for passengers with physical disabilities, such as the elderly, disabled people, or injured people, to use the help phone. Due to its convenience, it can also avoid physical damage caused by emergency operation.

[0028] When the receiver net 23 is used for a long time, the sound amplification hole 24 in the receiver net 23 will have a lot of dirt, at this time, it can be taken out by pulling it outwards with an external force, when it is necessary to install the receiver net 23, one side of the receiver net 23 is pressed against the first L-shaped connecting plate 20 on the upper and lower sides, then the first L-shaped connecting plate 20 will press the second spring 19, then the second spring 19 compresses the reserved space to put the receiver net 23 in, and then the second L-shaped connecting plate 22 and the first L-shaped connecting plate 20 are fixed to the receiver net 23 through the elastic recovery of the second spring 19 and the third spring 21 on both sides.

[0029] When it is necessary to install the receiver net 23, one side of the receiver net 23 can be pressed against the first L-shaped connecting plate 20 on the upper and lower sides, then the second spring 19 will be pressed by the first L-shaped connecting plate 20, then the second spring 19 compresses the reserved space to put the receiver net 23 into, and then the second L-shaped connecting plate 22 and the first L-shaped connecting plate 2 0 are fixed to the receiver net 23 through the elastic recovery of the second spring 19 and third spring 21 on both sides. Compared with the traditional device, the device can effectively remove stains and bacteria, ensure the clear sound quality of the receiver, and provide a more sanitary use environment for passengers. The receiver net 23 can be quickly removed and cleaned of foreign matter without the need for complex tools or a long disassembly process, thereby shortening the repair time and reducing the downtime of the help phone.

[0030] The shell 1 and the protective cover 2 are hinged by a hinge 25, and the hinge 25 is provided with two.

[0031] The shell 1 and the protective cover 2 are hinged by the hinge 25, and the hinge 25 is provided with two, which can effectively provide rotation support when the protective cover 2 is popped open, avoiding the situation that the protective cover 2 is popped open.

[0032] The shell 1 is internally fixedly provided with a calling device 13, the surface of the calling device 13 is movably provided with a help button 14 and a microphone 15, the number of the help button 14 and the microphone 15 is one group of two, one help button 14 and one microphone 15 form a group, and there are two groups in total, and the two groups are respectively located on the upper and lower parts of the calling device 13.

[0033] Through the two groups of help buttons 14 and microphones 15, the help button 14 and the microphone 15 on the upper part of the calling device 13 are suitable for normal people, and the help button 14 and the microphone 15 on the lower part of the calling device 13 are suitable for disabled people, so that different people can be effectively taken care of.

[0034] The outer surface of the calling device 13 is provided with a receiver 16, and the receiver 16 is located in the middle of the calling device 13; the outer surface of the calling device 13 is fixedly provided with an indicating device 17, and the indicating device 17 is fixedly installed below the help button 14 and the microphone 15.

[0035] Through the receiver 16, the people who need help can receive the instructions of the staff, and then the correct use method can be told to the people through the text description of the indicating device 17.

[0036] The shell 1 and the protective cover 2 are hingedly connected through a hinge 25, and the protective cover 2 is transparent.

[0037] The protective cover 2 is transparent, which can not only effectively protect the help telephone from being touched by the people and being damp and rusty in the non-use state, but also can not block the people in the use state.

[0038] The four ninety-degree angles formed by the four edges of the shell 1 are all set as round angles, and the fixed block 3 is made of rubber.

[0039] The four edges of the shell 1 are set as round angles, which can reduce the harm of the people hitting the shell 1, and the fixed block 3 is made of rubber, which can effectively prevent static electricity.

[0040] The working principle and the use process of the utility model are as follows:

[0041] When the protective cover 2 in normal state will drive the first connecting plate 10 on both sides to extrude the first spring 12 to produce elastic deformation and within the range of bearing, the second sliding groove 8 in the limiting block 7 will lock the second movable ball 9, when encountering emergency, the crowd will pull the second movable ball 9 outward through external force, so that the second movable ball 9 smoothly slides out of the second sliding groove 8, at the same time, the second movable ball 9 drives the connecting rod 5 to slide outward in the first sliding groove 6, then it will also drive the first movable ball 4 to move in the fixed block 3, at this time, the second movable ball 9 is unlocked, so that the first connecting plate 10 is opened outward by the elastic recovery of the first spring 12, at the same time, the protective cover 2 is also opened.

[0042] When the earphone net 23 is used for a long time, the sound amplification hole 24 in the earphone net 23 will have a lot of dirt, at this time, it can be taken out by pulling outward through external force, when the earphone net 23 needs to be installed, the first L-shaped connecting plate 20 on both sides is extruded through one side of the earphone net 23, then the first L-shaped connecting plate 20 will extrude the second spring 19, then the earphone net 23 is put into the reserved space through the compression of the second spring 19, then the second L-shaped connecting plate 22 and the first L-shaped connecting plate 20 are fixed to the earphone net 23 through the elastic recovery of the second spring 19 and the third spring 21.
