Door lock

A door lock, comprising:

• a door hook;
• a cam that selectively engages the door hook;
• a main sliding block, the main sliding block being able to move to and fro between a locked position and a released position along a first direction, and the main sliding block being able to lock the door lock when at the locked position to prevent removal of the door hook from the cam, and the main sliding block being able to release the door lock when at the released position to permit removal of the door hook from the cam;
• an indicating sliding block that is able to move to and fro with respect to the main sliding block and along the first direction when the main sliding block moves to and fro between the locked position and the released position along the first direction, wherein the indicating sliding block includes a rotation bevel that engages the main sliding block to rotate the indicating sliding block and define an included angle between the sliding block and the main sliding block when the main sliding block moves from the released position to the locked position;
• an indicating latch that is able to move to and fro on an upper surface of the indicating sliding block, and the indicating latch being able to accordingly move to and fro along a second direction that is orthogonal with respect to the first direction when the indicating sliding block moves to and fro along the first direction;
• and
• a switching apparatus, with the indicating latch being able to close or disconnect the switching apparatus.

• a cam that selectively engages the door hook;
• a main sliding block, the main sliding block being able to move to and fro between a locked position and a released position along a first direction, and the main sliding block being able to lock the door lock when at the locked position to prevent removal of the door hook from the cam, and the main sliding block being able to release the door lock when at the released position to permit removal of the door hook from the cam;
• an indicating sliding block that is able to move to and fro with respect to the main sliding block and along the first direction when the main sliding block moves to and fro between the locked position and the released position along the first direction;
• an indicating latch that is able to move to and fro on an upper surface of the indicating sliding block, and the indicating latch being able to accordingly move to and fro along a second direction that is orthogonal with respect to the first direction when the indicating sliding block moves to and fro along the first direction;
• and
• a switching apparatus, with the indicting latch being able to close or disconnect the switching apparatus;
• wherein:
• the indicating sliding block is arranged at one side of the main sliding block, and the main sliding block brings the indicating sliding block to move from a closed position to an open position.

• and
• a switching apparatus, with the indicating latch being able to close or disconnect the switching apparatus
• wherein:
• the indicating sliding block is arranged at one side of the main sliding block, and the main sliding block brings the indicating sliding block to move from a closed position to an open position;
• the indicating sliding block comprises a stepped part, and the stepped part comprises an upper step and a lower step that are arranged by way of connection;
• a bearing surface and a recess are provided on the upper step, the bearing surface is arranged at a distal end of the upper step, the bearing surface is higher than the recess, a distal end of the recess is connected to the bearing surface, and an indicating sliding block restoration part is provided at an outer side face at a proximal end of the recess;
• an indicating sliding block release part is provided on an upper surface at a distal end of the lower step, a blocking surface is provided at a proximal end of the lower step, and the blocking surface is used for blocking the movement of the main sliding block when the main sliding block moves from the locked position to the released position;
• and
• an indicating sliding block protrusion locking claw extends out of an outer side face at the distal end of the lower step.

A door lock, comprising:

• a main sliding block configured to move to and fro between a locked position and a released position along a first direction, wherein the main sliding block locks the door lock when at the locked position and releases the door lock when at the released position;
• and
• an indicating sliding block that engages and is supported by a face-to-face surface engagement with and is movable independently with respect to the main sliding block, wherein:
• movement of the main sliding block translates into movement of the indicating sliding block;
• the indicating sliding block is able to move to and fro between a closed position and an open position along the first direction when the main sliding block moves to and fro between the locked position and the released position along the first direction;
• and
• the closed position and the open position of the indicating sliding block are used for indicating whether the door lock is in a locked state or in a released state.
