The fixed part is detachably connected with the door lock panel, and an opening matched with the poking part is formed in the fixed part. The reset part is abutted against the door lock panel, when the positioning block slides out of the positioning concave hole along the guide rail, the reset part compresses the positioning block, and when the fixing part is connected with the door lock panel, the poking part stretches out from the opening of the fixing part, so that the steering base is fixed through the poking part.

The door lock that this embodiment provided through the cooperation of location shrinkage pool and locating piece, realizes turning to the subassembly and is fixed in a plurality of positions on the rotatory circumference of handle to realize the adjustment of handle rotation position, realize the switching-over of handle promptly, need not dismantle the door lock and can realize the switching-over of handle, the handle switching-over is convenient.

Specifically, when the steering assembly is located at any position, the positioning block stretches into the positioning concave hole, at the moment, the degree of freedom of the steering assembly in the circumferential direction is limited by the positioning block, when a user rotates the handle to unlock the door lock, the fixing plate which is abutted against the elastic piece rotates along with the shaft body, the elastic piece is compressed under the action of the arc-shaped groove and the fixing plate, after the door lock is unlocked, the elastic piece is deformed in a recovery mode, and the elastic piece drives the fixing plate to rotate so that the handle rotates and returns to the initial position. The handle can be reset automatically when the user uses each time, so that the user can use the handle more conveniently.

The locating piece is fixed in on the door lock panel through the fixed part, when the needs are to the handle commutate, the user stir the portion of stirring that stretches out from the opening and make the locating piece shift out the location shrinkage pool along the guide rail, turn to the subassembly and can rotate along with the handle this moment, when turning to the subassembly and rotating to predetermineeing the position, stretch into the location shrinkage pool through the locating piece under the effect of the portion of stirring that reset part and user stir to make turn to the subassembly and lock in circumference, handle pivoted initial position changes this moment, and the handle switching-over is accomplished. In this embodiment, the number of the positioning concave holes is two, the preset positions corresponding to the positioning concave holes are two, and the handle can be adjusted for 180 degrees each time to perform reversing.

Wherein, the upper end and the lower extreme that turn to the subassembly are located to the location shrinkage pool, and the lower extreme that turns to the subassembly is located to the locating piece, is convenient for reduce the space that lock subassembly occupy in the left and right sides, and lock subassembly installation required space is littleer.

It should be noted that the circumferential portion of the fixing plate is embedded in the bearing and is engaged with the inner wall of the bearing, and the bearing can reduce resistance in the process of rotating the handle, so that the handle can rotate more smoothly. Meanwhile, the rotation precision of the steering shaft is high, the possibility of interference between the steering shaft and the steering assembly in the process of rotating the handle can be reduced, the abrasion of the steering shaft and the steering assembly is convenient to reduce, and the service life of the door lock is prolonged.

In summary, according to the door lock provided by the application, the positioning concave holes are matched with the positioning blocks, so that the steering assembly is fixed at a plurality of positions on the rotating circumference of the handle, the positioning concave holes matched with the positioning blocks are adjusted, the rotating position of the handle can be adjusted, namely, the handle is reversed, the handle is installed without correcting the front and back directions, and the reversing is convenient.
