Description
Technical Field
[0001] The utility model belongs to the technical field of steel locking rod pieces, in particular to a steel locking rod piece. Background Art
[0002] The locking lever mechanism is a mechanical system used to lock and unlock vehicle doors. Its core function is to ensure that the doors remain closed while the vehicle is in motion, preventing unauthorized access and providing a quick escape route for occupants in an emergency.
[0003] Safety is a key consideration in the design of vehicle door lock lever mechanisms. Modern vehicle lock lever mechanisms must not only resist physical attacks like picking and drilling, but also prevent technical unlocking. Furthermore, an emergency unlock function is an integral part of the design, ensuring occupants can quickly escape the vehicle in emergencies such as drowning or a collision. With this in mind, we propose a steel lock lever. Utility Model Content

[0007] In this technical solution, the fixing plate is fixed to the inside of the car door by a number of bolts and a number of round holes, and the locking rod piece is connected to the lock body mounting plate by a hexagon socket bolt and a nut. When the personnel needs to open the car door, the personnel can pull the door handle, and the door handle will drive the locking rod piece to move, and the locking rod piece will rotate at the same time. The movement of the locking rod piece will drive the lock hook to rotate through the flat head pin shaft 2, so that the lock hook will rotate with the flat head pin shaft 1 as the axis, and the flat head pin shaft 2 will rotate in the lock hook. The rotation of the lock hook can hook the lock body structure, thereby achieving the unlocking effect. The operation is simple and quick, ensuring that the personnel can quickly open the car door in an emergency. The locking rod piece is fixed to the lock body mounting plate by a hexagon socket bolt and a nut, which is convenient for personnel to install and disassemble the locking rod piece.
[0008] In the above technical solution, further, a plurality of circular holes are opened on one side of the fixing plate.
[0009] In this technical solution, it is ensured that personnel can fix the fixing plate to the inner side of the vehicle door through a plurality of round holes and a plurality of bolts.
[0010] In the above technical solution, further, the flat head pin shaft is tightly welded to the lock hook.
[0011] In this technical solution, the structural stability of the flat head pin shaft and the lock hook is ensured.
[0012] In the above technical solution, further, the flat head pin shaft 2 is tightly welded to the locking rod piece.
[0013] In this technical solution, the structural stability of the flat head pin shaft 2 and the locking rod piece is ensured.
[0014] In the above technical solution, further, the locking hook is made of steel.

[0016] The beneficial effects of the utility model are:
[0017] The steel locking rod piece is provided with a locking rod piece, and under the mutual cooperation of the locking rod piece, the flat head pin shaft 2, the lock hook and the flat head pin shaft 1, the lock hook can be rotated to hook the lock body structure, thereby achieving the unlocking effect. The operation is simple and fast, ensuring that personnel can quickly open the car door in an emergency. At the same time, the fixed plate, the lock hook and the locking rod piece are connected by the flat head pin shaft 1 and the flat head pin shaft 2. The mechanical structure has good elasticity and ductility. At the same time, the lock hook is a steel sheet structure with strong hardness and is not easy to deform, making it difficult for the car door to be pried open by external force.
