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 utility model discloses a shortcoming that the invention aim at overcome prior art exists designs a run-through cab apron locking and from clamping device, can satisfy the cab apron and install and remove the requirement fast, guarantees 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 utility model relates to a run through cab apron locking from clamping the device and being connected with the mounting groove of cab apron through mounting hole and round pin axle and split pin.
Compared with the prior art, the utility model, can realize the quick installation and dismantlement of cab apron, simultaneously or after drawing the pull ring to spacing to the one side that spacing pull rod has the arch alone, make the arch of spacing pull rod block at the tip of mounting groove, make spacing pull rod be in the card and stop the commentaries on classics state, the cab apron unblock, when drawing a pull ring alone, need to carry on the same operation to another pull ring too, can make the cab apron unblock; 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 main structure principle of the present invention.
Fig. 2 is a schematic view of the connection relationship between the present invention and the installation groove of the cab apron.
Fig. 3 is a schematic view of the normal state of the present invention.
