[0032] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0033] The protective devices on existing conventional passenger trains with open structures often present several issues. They are often welded, non-openable structures or utilize outdated locking mechanisms. Functionally, these locking mechanisms are quite outdated, making them extremely inconvenient to use and maintain. Opening and closing the protective device requires staff to carry a key. This is particularly inconvenient due to the structural limitations of the open area, and key storage is also challenging, making it prone to loss and potentially affecting the proper functioning of the protective device.

[0034] like Figure 1 and Figure 2 As shown, the present application proposes a movable guardrail device A, which is installed on the door frame B of a railway passenger car, including a guardrail frame 1, a rotating shaft seat 2 and a locking side fixing seat 3, and a guardrail net 11 is arranged in the guardrail frame 1; the rotating shaft seat 2 is installed on the right side of the guardrail frame 1, and the guardrail frame 1 and the rotating shaft seat 2 are rotatably connected through a rotating shaft 21; the locking side fixing seat 3 is arranged on one side of the guardrail frame 1, and a locking device 4 is arranged on the locking side fixing seat 3, and the guardrail frame 1 is locked on the locking side fixing seat 3 through the locking device 4.

[0035] The principles of this application are:

[0036] The movable guardrail device A of the present application utilizes a pivot seat 2 to enable the guardrail frame 1 to be opened and closed by rotation. In the closed state, the guardrail frame 1 is securely locked to the locking-side mounting seat 3 via a locking device 4, with the guardrail mesh 11 providing protection. To open, the locking device 4 is operated to unlock the guardrail frame 1, allowing it to rotate about the pivot axis and open. To close, the guardrail frame 1 is rotated back to its original position and relocked. Keyless operation enhances ease of use, while enabling quick unlocking in emergencies, facilitating rapid evacuation. Its operating principle is simple and reliable, balancing safety, convenience, and emergency response capabilities, meeting the high demands placed on protective devices on modern railway passenger trains.

[0037] like Figure 3As shown, in one embodiment, the locking device 4 is a latch 41. The lower end of the latch can be inserted through the locking-side fixing seat 3 and into the latch hole of the guardrail frame 1 to lock the guardrail frame 1. The latch achieves locking through mechanical insertion, which is simple, reliable, and less prone to failure. The latch design eliminates the need for a key; personnel can simply lock and unlock manually, simplifying the operation process.

[0038] like Figure 6 As shown, in one embodiment, the locking device 4 is a self-locking spring-type telescopic plug-in pin 42, which is mounted on the locking side fixing seat 3. The self-locking spring-type telescopic plug-in pin locks or unlocks the guardrail frame 1 by driving the pin core. The design of the self-locking spring-type telescopic plug-in pin makes the locking and unlocking process extremely simple. The guardrail frame 1 can be fixed or released by simply pushing or pulling the pin core, greatly improving operational efficiency and convenience. The self-locking spring-type telescopic plug-in pin has an automatic locking feature. Once the guardrail frame 1 is closed, the plug-in pin automatically pops out and locks, ensuring that the guardrail frame 1 will not accidentally open during driving, thereby effectively protecting the safety of passengers.

[0039] like Figure 4 As shown, in one embodiment, the locking side fixing seat 3 includes a first limiting side plate 31 and an upper limit mounting plate 32. The first limiting side plate 31 is arranged on the front side of the locking side fixing seat 3, and the upper limit mounting plate 32 is arranged on the upper end of the locking side fixing seat 3. The locking side fixing seat 3 is provided with a latch through hole 33. The first limiting side plate 31 is arranged on the front side of the locking side fixing seat 3, which can effectively limit the position of the guardrail frame 1 in the closed state and prevent it from shaking back and forth. The upper limit mounting plate 32 is arranged on the upper end of the locking side fixing seat 3, which can limit the up and down movement of the guardrail frame 1 and prevent it from being separated from the fixing seat due to external force. The latch through hole 33 provided on the locking side fixing seat 3 cooperates with the latch to ensure that the latch can be accurately inserted into the latch hole of the guardrail frame 1 to achieve a secure lock.

[0040] like Figure 5 As shown, in one embodiment, the movable guardrail device A further includes a lower locking side mounting bracket 5, which is disposed below the left side of the guardrail frame 1 and is used to define a locked position of the guardrail frame 1. The lower locking side mounting bracket 5 provides an additional support point for the guardrail frame 1, particularly below the lower portion thereof, which helps to resist downward or lateral external forces that the guardrail frame 1 may be subjected to during use, thereby enhancing the stability of the entire guardrail device.

[0041] like Figure 5 As shown, in one embodiment, the lower locking side fixing seat 5 includes a second limiting side plate 51 and a lower limiting plate 52, the second limiting side plate 51 is arranged on the front side of the lower locking side fixing seat 5, and the lower limiting plate 52 is arranged at the lower end of the lower locking side fixing seat 5.

[0042] like Figure 3 As shown, in one embodiment, a threaded plug hole 12 is provided on the right side of the guardrail frame 1, corresponding to the mounting screw of the rotating shaft seat 2. A threaded plug 13 is installed in the threaded plug hole 12. When installation or maintenance is required, the threaded plug 13 can be easily removed, allowing maintenance personnel to easily access the mounting screw. After installation or maintenance is completed, the threaded plug 13 can be easily reinstalled to restore the integrity and functionality of the guardrail frame 1.

[0043] like Figure 1 As shown, the present application also proposes a protective door device for a railway passenger car, comprising a door frame B and a movable guardrail device A; the movable guardrail device A is installed in the door frame B. The installation of the movable guardrail device A makes the protective door device extremely flexible and adaptable. As needed, the guardrail can be easily opened or closed to adapt to different usage scenarios and needs, such as passengers getting on and off the car, loading and unloading cargo, or special sightseeing needs. The movable guardrail device A can be securely locked in the door frame B in the closed state, providing an effective safety barrier for passengers and staff. This design prevents passengers from accidentally falling or being injured by external objects during travel, greatly improving the safety of railway passenger cars.
