Embodiment Construction
[0038] Without loss of generality, this article takes the door system at one end of a rail vehicle as an example, and introduces the hinge locking device, locking device and door system together.
[0039] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0040] Please refer to figure 1 , figure 1 A schematic axonometric view of an end door system of a rail vehicle in a specific embodiment is shown.
[0041] In this embodiment, the end door system of the rail vehicle includes a door frame 1 and two door panels 2 installed in the door frame 1, in order to illustrate the orientation, wherein the left side of a door panel 2 is hinged to the left frame wall of the door frame 1, The right side of the other door panel 2 is hinged with the right frame wall of the door frame 1, and the door fram...

The invention discloses a hinge locking device, a locking device and a railway vehicle door system. The hinge locking device is used for the door system. The door system comprises a door frame and door plates mounted on the door frame. Each door plate comprises two or more door leaves. The hinge locking device comprises a first hinge plate, a second hinge plate and a lock rod. One side of the first hinge plate is fixedly connected with the first door leaves, and the other side of the first hinge plate and the lock rod are hinged. The first door leaves are close to the hinged sides of the doorplates and the door frame. One side of the second hinge plate and the lock rod are hinged, and the other side of the second hinge plate is fixedly connected with the second door leaves. The lock rod can rotate around the axis of the lock rod, and at least one end of the lock rod is provided with a lock hook with a hook groove. A lock shaft cooperating with the hook grooves is mounted on the door frame. According to the configuration, the first door leaves are in the closed state, and the lock hooks are driven by rotation of the lock rod so that the lock shaft can be embedded in the hook grooves. A locking component is further included and can fix the relative positions of the lock rod and the door plates. The hinge locking device achieves the dual functions of the hinge and locking.
Description
technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a hinge locking device of a door system, a locking device and a rail vehicle door system. Background technique [0002] With the rapid development of rail vehicles, the requirements for rail vehicles in different application conditions are getting higher and higher. [0003] At present, in the door system of rail vehicles, such as the end door system, the hinge device for realizing the rotation of the end door and the locking device for realizing the locking of the end door are separated, and each realizes its own function. At the same time, the existing hinge forms cannot reinforce the door leaf, especially for freight rail vehicles, whose end doors are usually taller and wider, with poor rigidity, and cannot meet the requirements of the door system as the development demands. Air tightness requirements. [0004] Similar problems as described above also exist for other d...
