Skirtboard lock and rail vehicle

Abstract

The invention provides a skirtboard lock and a rail vehicle. The skirtboard lock comprises a lock shell provided with a hole in the center and a locking screw rod arranged in the lock shell in a penetrating mode; the tail end of the locking screw rod is a prismatic mounting section; the skirtboard lock also comprises a display fastener arranged between the lock shell and the mounting section; the bottom of the fastener is provided with a mounting hole matched with the mounting section in shape; the mounting section is coaxially clamped in the mounting hole; clamp hooks are fixedly arranged at the periphery of the top end of the display fastener; a clamping part is formed at the edge of the opening in the top end of the lock shell; the display fastener and the clamping part are clamped and fixed in the lock shell by the clamp hooks. The skirtboard lock has the beneficial effects that the synchronous rotation of the display fastener and the locking screw rod is realized by matching of the mounting hole and the tail end of the locking screw rod, so the loosening phenomenon of a locking rod screw rod is convenient to observe; the display fastener is fixed in the lock shell by clamping the clamp hooks and the clamping part. The display fastener is very convenient to assemble and disassemble due to the clamping mode.

Description

technical field [0001] The invention relates to high-speed train technology, in particular to an apron lock and a railway vehicle. Background technique [0002] The equipment cabin floor of the high-speed train is fixed on the car body through the skirt plate lock, figure 1 It is a schematic structural diagram of the skirt lock in the prior art. Referring to this figure, the skirt lock includes a lock housing 42, a locking screw 43, a lock nut 45 and a car body nut 46. When the skirt lock is used to fix the equipment cabin floor, First, the hexagonal lock nut 45 can be installed on the shell of the lock case 42, and then the two are integrally installed in the corresponding assembly holes on the bottom plate, so that the lock case 42 and the bottom plate are fixed together, and finally the locking screw 43 passes through the lock The shell is fixedly connected with the nut 46 on the car body, and the base plate is fixed on the car body. [0003] Due to the vibration during...

Problems solved by technology

[0005] The defect of this method is that, since the clip 8 and the locking screw 43 are relatively fixed by means of interference fit, it is difficult to remove the clip from the locking screw, and the clip 8 and the locking screw 43 can only be unscrewed together. , so that all the parts of the skirt plate lock fall out, which brings inconvenience to the disassembly process
