Description

Technical Field

[0001] This application relates to the field of trains, and more specifically to a protective skirt. Background Technology

[0002] When a train stops in a section and cannot run, and an emergency such as a fire or terrorist hijacking occurs, the emergency evacuation of passengers must be considered. When the train is on an elevated or ground-level track, passengers can evacuate via the passenger evacuation stairs at the passenger compartment doors to the cable trough cover platform in the section. When the train is in a tunnel, passengers can evacuate via the passenger compartment doors through the tunnel evacuation platform. Protective skirts are used to cover the inner side evacuation devices, or to open the skirts to pull out the inner side evacuation devices. Since the skirts are in direct contact with the ground when open, their strength must be guaranteed to prevent deformation due to impact. Therefore, there is a need for a protective skirt with high structural strength, high practicality, and easy opening. Summary of the Invention

[0026] Indicative protective skirt

[0027] refer to Figures 1 to 4 According to a preferred embodiment of the present invention, the protective skirt panel has the following structure: Figure 1 As shown, the protective skirt panel includes a plate 10, which is an arc-shaped plate. To improve the structural strength of the plate 10, multiple longitudinally arranged first reinforcing strips 11 and multiple transversely arranged second reinforcing strips 12 are provided on one side of the plate 10. The multiple first reinforcing strips 11 are spaced apart, and the multiple second reinforcing strips 12 are also spaced apart. It is worth mentioning that the multiple first reinforcing strips 11 and the multiple second reinforcing strips 12 together form a mesh structure to improve the structural strength of the plate 10 and prevent the plate 10 from deforming under pressure.

[0028] Specifically, the protective skirt also includes a plurality of rotary clamping locks 20, and the plate body 10 has a plurality of spaced mounting holes. The plurality of rotary clamping locks 20 respectively cooperate with the plurality of mounting holes, and the plurality of mounting holes are through holes. Specifically, each rotary clamping lock 20 includes a lock body 21, one end of which passes through the mounting hole and the other end abuts against the plate body 10. The connection between the lock body 21 and the mounting hole can be implemented as a sliding connection. Each rotary clamping lock 20 also includes a nut 22, which is threadedly connected to the surface of the lock body 21 passing through the mounting hole and abuts against the other side of the plate body 10, thereby defining the position of the lock body 21.

[0029] Furthermore, the lock body 21 also has a mating hole 2101 at its center, which penetrates the lock body 21. Each of the rotary locking locks 20 includes a first rotating rod 23, which is rotatably engaged with the mating hole 2101. Specifically, the first rotating rod 23 has a first connecting part 231, a first mating part 232, and a second connecting part 233. The first connecting part 231, the first mating part 232, and the second connecting part 233 are integrally formed. The first connecting part 231 is configured to engage with an external key, and the first mating part 232 is threadedly connected to the mating hole 2101. That is, by rotating the direction of the first connecting part 231, the first rotating rod 23 is driven to move along the axial direction of the mating hole 2101. In addition, each of the rotary clamping locks 20 further includes a second rotating rod 24. The second rotating rod 24 has a third connecting part 241 and a second mating part 242. The third connecting part 241 is connected to the second mating part 242, and the third connecting part 241 is fixedly mated with the second connecting part 233. That is, when the first rotating rod 23 rotates, the second rotating rod 24 rotates synchronously, and the ends of the second mating part 232 and the second connecting part 233 are spaced apart by a predetermined distance.

[0030] Specifically, each of the rotary clamping locks 20 further includes a sleeve 25. One end of the sleeve 25 is disposed on the mating hole 2101 and located at the end of the lock body 21 away from the plate 10, and the other end extends a predetermined distance toward the second mating part 232.

[0031] Specifically, each rotary locking lock 20 further includes a locking tongue 26. One end of the locking tongue 26 is fixed to the second mating part 242, and the other end extends outward and is configured to press against the outer door frame. Specifically, the locking tongue 26 is Z-shaped, having a fourth connecting part 261, a bent part 262, and a pressing part 263. The bent part 262 is connected to the fourth connecting part 261 and the pressing part 263, respectively. The fourth connecting part 261 is fixed to the second mating part 242, i.e., located between the ends of the second mating part 242 and the second connecting part 263. The pressing part 263 is configured to press against the outer door frame. Specifically, when the first rotating rod 23 rotates and moves outward... At a fixed distance, the second rotating member rotates synchronously by a predetermined angle, and the locking tongue 26 rotates synchronously by a predetermined angle. At this time, the fourth connecting part 261 contacts the top of the sleeve 25, where the rotation angle is 30 degrees. When the user continues to rotate, the fourth connecting part 261 of the locking tongue 26 will press against the sleeve 25, causing the sleeve 25 to deform. This causes the locking tongue 26 to continue moving closer to the plate 10 until the pressing part 263 of the locking tongue 26 engages with the outer door frame. It is important that the end of the pressing part 263 facing away from the bent part 262 has a concave edge structure, specifically as follows... Figure 2 As shown, the design of this structure facilitates the pressing part 263 to press against the outer door frame, so as to avoid the pressing part 263 being unable to press against the outer door frame due to interference problems.

[0032] In summary, the protective skirt panel described in the embodiments of this application is explained, which provides advantages such as high structural strength, high practicality, and convenient opening.

[0033] It is worth mentioning that, in this embodiment, the protective skirt has a simple structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the protective skirt provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.
