In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0039] In the description of this embodiment, unless otherwise specified, the term "plurality" refers to a quantity of two or more than two.

[0040] like Figures 1 to 11 As shown, a multifunctional conversion device for a door lock comprises a main body 1, a function selection knob 2, a conversion execution rod 3 and an adjustment rod 4;

[0041] The main body 1 is non-rotatably arranged inside the door lock, and a first through hole 11 is provided in the main body 1 for the conversion actuator 3 to pass through; two or more slots are provided on one end surface of the main body 1, and the slots include a first slot 12 and a second slot 13, and the depth of the first slot 12 is less than the depth of the second slot 13;

[0042] The function selection knob 2 can rotate and move axially, and the function selection knob 2 includes a plurality of insertion rods, and the insertion rods are inserted into the slots, and the insertion rods include a first insertion rod 21, and the length of the first insertion rod 21 is greater than the depth of the first slot 12, and the length of the first insertion rod 21 is less than or equal to the depth of the second slot 13; the function selection knob 2 is connected to the door lock;

[0043] The conversion actuator rod 3 can be elastically telescopically passed through the first through hole 11, one end of the conversion actuator rod 3 is fixedly connected to the function selection knob 2, the other end of the conversion actuator rod 3 is provided with a slot 31, and one side of the slot 31 is provided with an opening 32;

[0044] The adjusting rod 4 is fixedly connected to the knob rotor 9 of the door lock. When the first insert rod 21 is inserted into the first slot 12, the adjusting rod 4 is separated from the slot 31; when the first insert rod 21 is inserted into the second slot 13, the adjusting rod 4 is located in the slot 31, and the orientation of the opening 32 includes at least directly above and / or directly below.

[0045] The baffle plate 102 is detachably fixedly connected to the door lock, and the baffle plate 102 is arranged on a side close to the function selection knob 2 to prevent the function selection knob 2 from axially moving.

[0046] Working principle: when the insertion rod is inserted into the slot, the main body cannot rotate, so the multifunctional conversion device of the entire door lock is fixed; when the baffle is removed, the main body and / or the function selection knob are axially moved under the action of external force to separate the insertion rod from the slot. At this time, the function selection knob can be rotated to align the first insertion rod with a different slot. When the external force disappears, the first insertion rod is automatically inserted into the slot under the action of elastic force; when the function selection knob is rotated, the conversion actuator rod will rotate together with the function selection knob due to its fixed connection, so that the opening can be directed to different directions; after adjustment, the baffle is installed, and one end of the entire multifunctional conversion device is supported by the baffle and the other end is supported by the knob rotor, so it is fixed and cannot move, and the entire device cannot rotate.

[0047] When the first insertion rod is inserted into the first slot, due to the small depth of the first slot and the elastic and retractable conversion actuator rod, the conversion actuator rod will move to the left, so that the adjustment rod is completely separated from the slot 31, and the rotation direction of the knob rotor is not restricted and can be rotated forward or reverse, and the door can be opened and locked from both sides.

[0048] When the first plug rod is inserted into the second slot, since the depth of the second slot is greater than that of the first slot, the conversion actuator rod will move to the right under the action of elastic force, so that the adjustment rod can extend into the slot. At this time, when the opening is facing upward, the adjustment rod and the knob rotor can only rotate clockwise; when the opening is facing downward, the adjustment rod and the knob rotor can only rotate counterclockwise; when the opening is facing forward or backward, the adjustment rod and the knob rotor will not rotate. In this way, it can be achieved that the door can only be opened and locked from the outside or inside, or both sides cannot be locked.

[0049] From the above, it can be seen that the multifunctional conversion device of this door lock can make one door lock have the functions of multiple door locks at the same time.

[0050] Specifically, the number of the first slots 12 is 1, and the number of the second slots 13 is 3, so that when the first insertion rod is inserted into the first slot, the opening faces directly behind, and when the first slot is inserted into the three second slots respectively, the openings face directly above, directly in front, and directly below, respectively.

[0051] The plug rod also includes a second plug rod 22, the length of the second plug rod 22 is less than or equal to the depth of the second slot 13, the number of the first plug rod 21 is 1, and the number of the second plug rod 22 is 3, so that there is a plug rod in each slot.

[0052] It also includes an adjustment block 5, which is fixedly connected to the end of the function selection knob 2 away from the main body 1, so that the adjustment block, the function selection knob and the conversion actuator rod are elastically telescopic and adjustable in the axial direction. Each side of the adjustment block 5 is provided with an adjustment groove 51. The housing 10 of the door lock is provided with a placement port 101 that just accommodates the adjustment block. When the adjustment block is located in the placement port, the adjustment block cannot rotate, thereby fixing the adjustment block, the function selection knob and the conversion actuator rod. When the adjustment block is moved outward and out of the placement port, the adjustment block can be rotated, thereby driving the function selection knob and the conversion actuator rod to rotate together, so that the first plug rod can be inserted into different slots to achieve the purpose of adjusting the door lock function.

[0053] An identification mark is provided on one side of the front side of the adjustment block 5 near each edge, so as to facilitate identification of the functional state of the door lock at that time.
