It installs the back on the cab apron, has the loaded down with trivial details, the problem of consuming time and wasting force of ann's dismantlement. Therefore, the through-passage cab apron locking self-locking device is developed to meet the requirement of quick assembly and disassembly of the cab apron, and has social and economic values and wide application prospect.

The invention content is as follows:

the invention aims to overcome the defects in the prior art, and designs a through-passage cab apron locking self-clamping device which can meet the requirement of quick assembly and disassembly of a cab apron and ensure the driving safety.

In order to achieve the purpose, the main body structure of the through passage cab apron locking self-clamping device comprises a connecting rod, a locking tension spring, a groove-shaped lockset, a limiting pull rod, a pull ring, a mounting hole and a nylon sleeve; the two ends of the connecting rod are respectively connected with one end of a locking tension spring, the other end of the locking tension spring is connected with one end of a groove-shaped lock, the other end of the groove-shaped lock is connected with one end of a limiting pull rod, the other end of the limiting pull rod is connected with a pull ring of an annular structure, a mounting hole is formed in the end portion, close to the pull ring, of the limiting pull rod, and a nylon sleeve is arranged in the mounting hole.

The self-locking device for the through-passage cab apron is connected with the mounting groove of the cab apron through the mounting hole, the pin shaft and the cotter pin.

Compared with the prior art, the cab apron can be quickly installed and disassembled, the protrusions of the limiting pull rods are clamped at the end parts of the installation grooves after the pull rings are pulled to the limiting positions to the side, with the protrusions, of the limiting pull rods simultaneously or independently, so that the limiting pull rods are in a rotation stopping state, the cab apron is unlocked, and when one pull ring is pulled independently, the cab apron can be unlocked only by performing the same operation on the other pull ring; the cab apron mounting and dismounting device is simple in structure, can improve mounting and dismounting efficiency and safety of cab apron, and meets relative change requirements of two carriage stretching, compressing, side rolling, nodding, head raising extreme displacement curves and the like when a train runs at a high speed.

Description of the drawings:

fig. 1 is a schematic diagram of the principle of the main structure of the present invention.
