[0033] The profile door lock has a simple structure, reasonable design, and convenient operation. It can be embedded and installed in the door without installing a handle, takes up little space, and has a beautiful appearance. It is also applicable to both traditional sliding doors and hinged doors, and has strong adaptability. In actual operation, the outer door lock body 1 and the inner door lock body 2 can be respectively embedded and fixed on the front and rear sides of the door body through the first countersunk machine screw 16, without installing a handle protruding outward, and takes up little space overall and has a beautiful appearance. When the user stands inside the door and needs to lock the door, he only needs to move the inner lock slider 4 downward, and the inner lock slider 4 drives the paddle 83 in the lock body 8 to move downward through the lock head-inner slider connector 13, and the lock hook 82 pops out, and the door body is locked. When the user stands inside the door and needs to lock the door, he only needs to move the inner lock block toggle protrusion 52 on the inner lock block 5 to the right, which can drive the limiting protrusion 54 to slide to the right, so that the limiting protrusion 54 on the inner lock block fits with the horizontal slot of the ┐-shaped limiting hole 44 set in the lock slider 5, so that the inner lock slider 4 cannot slide up and down. At this time, the door body is locked, and it cannot be unlocked by the inner lock slider 4 or the inner lock slider 3 whether inside or outside the door. When the user stands inside the door and needs to unlock, he only needs to slide the inner lock block 5 to the left, and the limiting protrusion 54 of the inner lock block 5 fits with the vertical slot of the ┐-shaped limiting hole 44 set in the inner lock slider 4, so that the inner lock slider 4 can slide up and down. At this time, the locked state of the door body is released, and the user only needs to move the inner lock slider 4 upward, and the inner lock slider 4 drives the lock hook 82 in the lock body 8 to shrink through the lock head-inner slider connector 13, and the door body is unlocked. When the user needs to lock the door when standing outside the door, the key needs to be inserted into the lock body 6, and the lock body rotating block 7 needs to be rotated by rotating the key. The lock body rotating block 7 drives the inner lock block 5 to slide left and right during the rotation process. When the inner lock block 5 slides to fit the vertical slot of the ┐-shaped limiting hole 44 on the inner lock slider 4, the inner lock slider 4 can slide up and down. At this time, the inner lock slider 4 is driven to slide up and down by toggling the outer lock slider 3 to achieve locking or unlocking the door. When the user needs to lock the door when standing outside the door, the key needs to be inserted into the lock body 6, and the lock body rotating block 7 needs to be rotated by rotating the key. The lock body rotating block 7 drives the inner lock block 5 to slide left and right during the rotation process. When the inner lock block 5 slides to fit the horizontal slot of the ┐-shaped limiting hole 44 on the inner lock slider 4, the inner lock slider 5 cannot slide up and down. At this time, the door is locked. At this time, it is impossible to unlock the door by the inner lock slider 4 or the inner lock slider 3 whether inside or outside the door. Therefore, the door lock can be locked, locked and unlocked both inside and outside the door. From inside the door, it can be operated directly through the inner lock slider, while from outside the door, the corresponding key needs to be used for operation.

[0034] The above is only a preferred embodiment of the present invention, but the present invention should not be limited to the contents disclosed in the embodiment and the drawings, so any equivalent or modification completed without departing from the spirit disclosed in the present invention shall fall within the scope of protection of the present invention.
