[0002] In order to save space in subway cars and to ensure the lifespan of the seats, the seats are usually fixed to the subway car body. However, after passengers sit for a long time, the seats may become loose. Therefore, in order to ensure the safety of the seats, a cover plate needs to be installed at the bottom of the seats to ensure the balance and stability of the seats. At the same time, in order to meet fire protection requirements, fire extinguishers need to be installed at the bottom of the seats. Therefore, the cover plate at the bottom of the seats is particularly important.

[0003] However, most existing cover panels are spliced ​​together from multiple panels, resulting in poor support and a shorter service life for the equipment. At the same time, existing support cover panels provide poor protection for fire extinguishers during use, making them prone to falling and threatening passenger safety. In response, this utility model designs a detachable seat cover panel to solve the above problems. Utility Model Content

The operator then inserts the fire extinguisher 6 through the locking strap 9 into the clamping sub-frame 8 and the clamping main frame 801. Finally, the operator moves the locking block 901 so that the locking strap 9 is positioned... At the middle position of the fire extinguisher 6, the locking strap 9 is elastic, thus keeping it taut and ensuring the stability of the fire extinguisher. The operator then rotates the clamping handle 806, causing the clamping screw 805 to rotate, which in turn moves the clamping main frame 801 backward along the clamping rod 802, clamping the fire extinguisher 6 and ensuring its safety. The operator then releases the moving plate 703; at this point, the sliding block moves due to the action of the moving rod 701 and the moving spring 702. 7 moves backward, causing the fire extinguisher 6 to move to the rear end of the positioning plate 103. At this time, the operator inserts the baffle 706 into the positioning plate, thereby locking the moving plate 703. When it is necessary to remove the fire extinguisher 6, the operator only needs to pull out the baffle 706 and pull the moving plate 03 to move the slider 7 out, and then directly remove the fire extinguisher.
