DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model aims to provide a locomotive electric door lock to solve the problems existing in the prior art and to prevent the shaft from being deformed, bent or broken.

[0019] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] The utility model provides a locomotive electric door lock, such as Figures 1 to 4As shown, in this embodiment, it includes an electric door lock body, which includes a lock shell 16, a rotating shaft 12 rotatably connected to the lock shell 16, and a lock tongue 15 movably arranged in the lock shell 16 and capable of cooperating with the rotating shaft 12. A rotating shaft return spring 11 is sleeved on the rotating shaft 12. A fixed block 13 is fixedly arranged on the side of the rotating shaft 12 away from the lock tongue 15 inside the lock shell 16. The rotating shaft 12 abuts against the fixed block 13, and the fixed block 13 is provided with a groove adapted to the rotation of the rotating shaft 12.

[0021] The locomotive electric door lock provided by the utility model has the same switching principle as the traditional locomotive electric door lock, and is additionally provided with a fixed block 13. The fixed block 13 is fixed in the lock shell 16 by a plurality of protrusions arranged inside the lock shell 16 and cannot be moved. When the lock cylinder 18 and the rotating shaft 12 are pressed down and rotated to the lock faucet position, the rotating shaft 12 contacts the fixed block 13. At this time, the fixed block 13 plays a supporting and protective role, preventing the rotating shaft 12 from moving toward the fixed block 13, thereby preventing the rotating shaft 12 from being deformed or broken due to force.
