[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] Referring to the attached diagram: This voice broadcasting function device of the railway platform lifting protection device includes a housing 1, a lifting frame 2 slidably installed in the housing 1, and a rope 3 connected to the lifting frame 2. The housing 1 is also equipped with a display screen 4 from top to bottom, a scanning radar 5, a wireless sensor 6, and a speaker 7. A connecting unit 8 is installed inside the housing 1. A housing 9 is provided outside the speaker 7 to allow the speaker 7 to be inserted into it. A circular connecting barrier 91 is provided at the opening of the housing 9. A connecting node 10 is provided on the connecting barrier 91 to limit the final connection position of the housing 9 in the housing 1. A transverse slide 20 and a longitudinal slide 30 are provided on the connecting barrier 10 to guide the connecting unit 8 to the connecting node 10. The principle of this utility model is that the horn 7 is used to broadcast warning messages to persuade passengers in dangerous areas of the platform to leave. The horn 7 is a consumable and needs to be replaced after a certain period of use (i.e., when the horn malfunctions, such as crackling). The housing 9 is used to install the horn 7 and to connect to the enclosure 1. The connection between the housing 9 and the enclosure 1 is very convenient and does not require auxiliary tools. The connecting unit 9 is pre-installed on the enclosure 1 and is installed once. It does not need to be removed when the housing 9 is removed later. The connecting barrier 10 is used to increase the usable area of ​​the housing 9. That is, the connecting barrier 10 is provided with connecting nodes 10, transverse slides 20, and longitudinal... During assembly, the connecting unit 8 enters the transverse slide 20 and then slides into the longitudinal slide 30. It then slides further within the longitudinal slide 30 until it reaches the connecting node 10, which is positioned above. This allows the housing 9 to be suspended on the connecting unit 8, eliminating concerns about the connecting unit 8 detaching on its own. Furthermore, the trajectory structure formed by the connecting unit 8, connecting node 10, transverse slide 20, and longitudinal slide 30 consists of two units, symmetrically distributed vertically. This ensures the stability of the housing 9 during installation. The two connecting units 8 slide simultaneously within their respective trajectory structures, eliminating the need for separate operation.

[0021] The connecting barrier 91 is provided with a turning slide 40 that guides the connecting unit 8 from the horizontal slide 20 to the vertical slide 30. The turning slide 40 makes the horizontal slide 20 and the vertical slide 30 continuous in direction, so that the connecting unit 8 can slide smoothly from the horizontal slide 20 to the vertical slide 30. The turning slide 40 is arc-shaped, which can be clearly felt by the user and serves as a corresponding prompt. This allows the user to anticipate that the connecting unit 8 is about to reach the turning slide 40 and simultaneously enter the vertical slide 30, which can avoid the user's misjudgment.

[0022] The turning slide 40 has a fitting wall 401 that fully fits the surface of the connecting unit 8 when the connecting unit 8 reaches the turning slide 40, so that the connecting unit 8 is accurately positioned in the turning slide 40 to match the accuracy of the connecting unit 8 entering the turning slide 40 or the longitudinal slide 30.

[0023] The connecting unit 8 has an anti-detachment baffle 81 that can abut against the end face of the connecting barrier 91 and prevent the housing 9 and the box 1 from separating. The anti-detachment baffle 81 can abut against the end face of the connecting barrier 91, thereby preventing the housing 9 and the box 1 from separating to maintain a stable connection state. At the same time, the anti-detachment baffle 81 is configured as a cap-shaped structure formed on the connecting unit 8.

[0024] The transverse slide 20 has an inlet 201 on the connecting barrier 91 that matches the size of the anti-detachment baffle 81. The inlet 201 communicates with the transverse slide 20 and has a flared chamfer 2011 on one end face of the connecting barrier 91 to increase the inner diameter. In order to reduce the movement distance of the connecting unit 8 within the transverse slide 20, the transverse slide 20 does not have a lateral entry opening on the connecting barrier 91, and this is achieved by directly setting the inlet 201 on the connecting barrier 91. The configuration of the inlet 201 is the same as that of the anti-detachment baffle. The anti-detachment plate 81 has the same configuration and diameter, so the anti-detachment plate 81 can pass through the inlet 201 in the form of insertion. At the same time, the connecting unit 8 is located in the inlet 201. Moreover, the inlet 201 is interconnected with the transverse slide 20. Therefore, the connecting unit 8 can be detached from the inlet 201 and enter the transverse slide 20 by sliding. The flared chamfer 2011 enlarges part of the inner diameter of the inlet 201, that is, part of the inner diameter is larger than the outer diameter of the anti-detachment plate 81, which facilitates entry and prevents jamming.

[0025] The connection node 10 includes a placement space 101 formed on the connection enclosure 91 and allowing the connection unit 8 to be placed inside. The placement space 101 is interconnected with the longitudinal slide 30, that is, the connection unit 8 can enter the placement space 101 through the longitudinal slide 30 and then fit against the inner wall of the placement space 101, thereby achieving suspension and increasing stability.

[0026] The connecting unit 8 is a rod-shaped component, and part of it is a threaded segment that is threaded to the housing 1. It is a cylindrical rod-shaped component, and the threaded segment realizes its connection with the housing 1. The connecting unit 8 does not need to be removed when the housing 9 is removed. That is, by operating the housing 9, the connecting unit 8 can be removed by sliding.

[0027] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
