Description

Technical Field

[0001] This utility model relates to the field of locks, specifically a single-screw intelligent lock clutch reversing mechanism and a door lock. Background Technology

[0002] Door handles are an important component of door locks. By controlling the door handle to rotate the door lock's transmission mechanism, the door can be opened. In real life, different doors generally open from the left or right. When the door opens from the left, both the lock and the handle are located on the left side of the door. Generally, you need to turn the handle clockwise to open the door. When the door opens from the right, both the lock and the handle are located on the right side of the door. In this case, you generally need to turn the handle counterclockwise to open the door.

[0003] Whether the door opens to the left or the right, the structure of the door lock is generally the same. Therefore, if the door lock you buy is left-opening, it cannot be directly installed on a right-opening door. To solve this problem, you need to completely disassemble the door lock. In particular, you need to remove the handle, turn it 180 degrees, and then reconnect it to the rotating shaft to achieve the reversal. Due to the complex design of the door lock, it is quite troublesome to operate, and most users cannot disassemble and reassemble the door lock without special disassembly tools.

[0004] CN221096128U discloses a handle reversing mechanism, comprising: a housing having a cavity formed by a bottom wall and side walls extending around the bottom wall, with an opening in the bottom wall; a handle shaft, which is disposed through the opening in the housing, with one end of the handle shaft extending outward from the bottom wall of the housing connected to a door handle, and an opening groove provided at the top of one end of the handle shaft located in the cavity of the housing; a reversing plate, generally ring-shaped, fitted onto the handle shaft, with protrusions extending opposite to the inner ring of the reversing plate, the protrusions being movably connected to the opening groove of the handle shaft, so that the reversing plate and the handle shaft rotate synchronously; a reversing screw, detachably connected to the reversing plate; and a clutch knob, with stop blocks extending outward from opposite sides of the clutch knob, the stop blocks being used to limit the rotation of the reversing plate.

[0005] When reversing, remove the reversing screw from the reversing plate, lift the reversing plate facing the operator, move the reversing block out of the handle shaft's slot, and rotate it 180 degrees clockwise. At this point, the two grooves on the reversing plate will have swapped positions. After the reversing plate has rotated 180 degrees clockwise to its final position, reinstall the reversing screw on the reversing plate and secure it. At this point, the protrusion on the inner ring of the reversing screw will fall into the handle shaft's slot, allowing the reversing screw and handle shaft to rotate synchronously, thus completing the reversing.

[0006] In the existing technology, the commutation of the commutator plate is relatively complicated. Utility Model Content

[0007] The purpose of this utility model is to provide a single-screw intelligent lock clutch reversing mechanism and a door lock, which makes reversing more convenient.

[0008] To achieve the above objectives, this utility model provides a single-screw intelligent lock clutch reversing mechanism, including a housing, a handle shaft, a reversing plate, a clutch knob, a clutch motor, a reversing screw, and a return spring. The clutch knob is provided with a free-rotating pin, and the handle shaft has an open slot. The clutch motor drives the free-rotating pin to insert into the open slot and engage the handle shaft and the clutch knob. The return spring drives the free-rotating pin to disengage from the open slot. The reversing plate has a limiting part extending toward the housing, and the edge of the reversing plate has a first abutment part and a second abutment part. The housing is detachably connected to the reversing screw, and the reversing plate is fixedly connected to the handle shaft. The reversing plate can rotate from a left-open position where the first abutment part abuts against the right side of the reversing screw to a right-open position where the second abutment part abuts against the left side of the reversing screw. The housing has a first limiting engagement part and a second limiting engagement part near the reversing screw for cooperating with the limiting part.

[0009] In one embodiment of this utility model, the reversing screw and the clutch motor are located on both sides of the handle shaft.

[0010] In one embodiment of the present invention, the commutator plate is provided with a fixing protrusion for inserting into the opening slot.

[0011] In one embodiment of this utility model, the housing has a disassembly window corresponding to the reversing screw.

[0012] In one embodiment of the present invention, the reversing plate is provided with an arc-shaped clearance section located between the first abutment portion and the second abutment portion.

[0013] In one embodiment of the present invention, the limiting part is disposed in the middle of the arc-shaped avoidance section.

[0014] In one embodiment of the present invention, the limiting portion bends from the arc-shaped clearance section toward the surface of the housing.

[0015] In one embodiment of this utility model, a support ring is provided between the reversing plate and the housing, and a retaining ring is connected to the handle shaft between the clutch knob and the reversing plate. A retaining ring is provided between the retaining ring and the reversing plate.

[0016] In one embodiment of the present invention, the housing is provided with a boss that is connected to the reversing screw.

[0017] In one embodiment of this utility model, the first limiting fitting part and the second limiting fitting part are the two side surfaces of the boss.

[0018] In this invention, the reversing plate and the handle shaft are fixed relative to each other. To reverse the direction, simply remove the reversing screw, rotate the handle 180 degrees, and then reinstall the reversing screw to complete the reversing. This is simpler and faster than the prior art. Attached Figure Description
