The second connecting plate 5 is used to securely connect the side end wall 3 to the top end wall 2. The L-shaped connector is formed by bending a stainless steel plate. The L-shaped connector 6 allows the end wall assembly to be positioned perpendicularly relative to the bottom bracket 1.1 and the vehicle body floor. The gap between the end wall assembly and the bottom bracket 1.1 is also filled with an adhesive. This adhesive not only increases the connection strength between the end wall assembly and the bottom bracket 1.1, but also provides a certain sealing effect. The adhesive must have a certain fireproofing function to ensure the fireproof performance of the partition wall assembly.

[0055] The method of using the above-mentioned rail vehicle partition wall device is as follows: connect the fixing seat 4.2 of the connecting component 4 to the end wall component through T-bolts, then assemble the end wall component with the support bracket 1, and connect it to the end wall component through the connecting groove 1 and T-bolts on the support bracket 1, and then rotate the connecting plate 1 4.1 of the connecting component 4 to the connecting beam of the support bracket 1 to realize the connection between the connecting plate 1 4.1 and the support bracket 1.

[0056] It should be noted that when setting up the connecting assembly 4, if the connecting plate 1 4.1 is connected to the supporting bracket 1 first, the assembly accuracy of the end wall assembly must be ensured during the assembly process so that the fixing seat 2 4.2 can be accurately engaged with the top of the end wall assembly after rotation.
