[0027] See also Figure 1-Figure 5 The utility model provides a technical solution: a rail car side door lock, comprising a door lock frame 1 and a lock strike frame 2, the door lock frame 1 is located on the side of the lock strike frame 2, and the door lock frame 1 and the lock strike frame 2 are close to and in contact with each other, handles 3 are movably installed on the inner walls of both sides of the door lock frame 1, and adjusting gears 11 are fixedly installed on the outer sides of two adjacent handles 3, a fixing plate 6 is fixedly installed inside the door lock frame 1, and a movable frame 4 is movably installed between the two adjacent fixing plates 6, one end of the movable frame 4 passes through the door lock frame 1 and extends to the interior of the lock strike frame 2, a lock strike 8 is provided inside the lock strike frame 2, the movable frame 4 extends into the lock strike frame 2 and is engaged with the lock strike to complete the connection between the door lock frame 1 and the lock strike frame 2.

[0028] In this embodiment, the movable frame 4 is U-shaped, a tooth block portion is provided in the U groove of the movable frame 4, the adjusting gear 11 is meshedly connected with the tooth block portion, and the adjusting gear 11 is connected to the movable frame 4 through the tooth block portion.

[0029] In this embodiment, a telescopic cylinder 5 is fixedly installed on the inner wall of the door lock frame 1, and a connecting plate 12 is provided at the end of the telescopic cylinder 5. A second push column 13 is fixedly installed inside the connecting plate 12, and a push block 16 and a sliding block 17 are fixedly installed at both ends of the second push column 13. A sliding groove 18 matching the sliding block 17 is provided on the fixed plate 6. A second compression spring 14 is provided on the outer side of the second push column 13. The second compression spring 14 is located between the connecting plate 12 and the sliding block 17, and is fixedly connected to both of them.

[0030] In this embodiment, an adjustment cavity 20 is opened inside the fixed plate 6, and a third compression spring 19 and a limit block 21 are fixedly installed inside the adjustment cavity 20. The top end of the third compression spring 19 is fixedly connected to the limit column 15, and the limit column 15 is in contact with the limit block 21. The bottom end of the push block 16 and the top end of the limit column 15 are both opened with matching bevel edges.

[0031] In this embodiment, a first pushing column 7 is fixedly installed at the other end of the pushing block 16. The first pushing column 7 passes through the door lock frame 1 and extends into the lock frame 2. A sliding plate 9 is movably installed in the lock frame 2. A first compression spring 10 is provided at the bottom end of the sliding plate 9. The side of the sliding plate 9 is in contact with the first pushing column 7.

[0033] This embodiment also discloses a rail vehicle door, which is applied to the rail vehicle side door lock in the above embodiment.

[0034] Working principle of this embodiment: When the railcar side door lock is used with the railcar door, the handle 3 is held and rotated counterclockwise. When the handle 3 is rotated, the adjusting gear 11 is driven to rotate counterclockwise. The adjusting gear 11 causes the movable frame 4 to move toward the lock frame 2 through the tooth block portion, and the movable frame 4 is extended into the lock frame 2. When the movable frame 4 contacts the lock 8 in the lock frame 2, the connecting plate 12 is also moved toward the lock frame 2 through the operation of the telescopic cylinder 5. When the connecting plate 12 moves, it drives the pushing block 16 to move. During the movement of the pushing block 16, the pushing block 16 will cause the limiting column 15 to enter the adjusting chamber 20. When the pushing block 16 passes through the limiting column 15, the limiting column 15 will return to its original position under the elastic force of the third compression spring 19. At the same time, when the pushing block 16 moves, it will drive the first pushing column 7 to make the side of the sliding plate 9 enter the moving frame 4, fix the moving frame 4, and prevent the moving frame 4 from moving out of the lock frame 2. Conversely, it will make the moving frame 4 move out of the lock frame 2, so as to achieve the separation between the door lock frame 1 and the lock frame 2.
