Description
The uncoupling rod safety lock is a kind of lockset, is particularly suitable for the locking of passenger train uncoupling rod.
At present, the lock mode that connects its uncoupling rod of hitch of usefulness between the rolling stock is the iron wire binding, and because of iron wire is easily lightened restrictions on, a lot of hitch separation accidents once took place the easy lancet of other personnel, causes the certain economic loss to railway transportation production.
The purpose of this utility model will solve above-mentioned uncoupling rod exactly can not blocked problem, studies a kind ofly can lock special lockset uncoupling rod, safe and reliable.
The purpose of this utility model can realize in the following manner.
Design two opposed locking closures 1,2, be associated with the bolt 3 of a tongue with lock mutually with these two locking closures 1,2, locking closure 1 is provided with axle sleeve 7, and locking closure 2 is provided with nut 4.The triangle gate lock key use that matches in this safety lock and the passenger vehicle.
The safety lock construction is simple, easy to install, cost is low, and it is installed in both sides, uncoupling lever bracket hole, tights a bolt 3 with triangle gate lock key in the passenger vehicle, can realize that with the uncoupling rod locking, anti-locking hook guarantees safety.
Accompanying drawing is an embodiment of the present utility model.
Fig. 1 is uncoupling rod safety lock structure and scheme of installation, is respectively triangle gate lock key in existing uncoupling lever bracket, uncoupling rod, the passenger vehicle shown in the dotted line among the figure.
Fig. 2, Fig. 3 are respectively elevation, the lateral views of locking closure 1
Fig. 4, Fig. 5 are respectively elevation, the lateral views of locking closure 2
Fig. 6, Fig. 7 are respectively elevation, the A views of bolt 3
The uncoupling rod safety lock has two dish-type locking closures 1,2 that are stamped to form with steel sheet in the present embodiment, be associated with the bolt 3 of a tongue with lock mutually with locking closure 1,2, be welded with axle sleeve 7 on the locking closure 1, be welded with a nut 4 on the locking closure 2, its cross section of dead bolt end triangular in shape 8 of bolt 3, it is arranged in axle sleeve 7, and the end that bolt 3 matches with nut 4 has screw thread 9.A spring pad 6 is arranged, opening Xiao 5 who also has a hole 10 and match with it on the bolt 3.Locking closure 1,2 is the dish-type locking closure, and its edge, position by uncoupling rod is the garden and lacks type 11,12.
