Description

Technical Field

[0001] This utility model relates to the field of locks, specifically a door lock with quick-reversible direction. 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 clutch shaft being disposed through the opening in the housing, with one end of the clutch 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 clutch shaft located in the cavity of the housing; a reversing plate, generally ring-shaped, sleeved on the clutch shaft, with protrusions extending opposite to the inner ring of the reversing plate, the protrusions being movably connected to the opening groove of the clutch shaft, so that the reversing plate and the clutch shaft rotate synchronously; a reversing screw being detachably connected to the reversing plate; and a clutch disc having stop blocks extending outward from opposite sides of the clutch disc, 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 opening slot of the clutch shaft, and rotate it 180 degrees clockwise. At this time, the two grooves of the reversing plate will be swapped. After the reversing plate is rotated 180 degrees clockwise into place, reinstall the reversing screw on the reversing plate and fix it. At this time, the protrusion of the inner ring of the reversing screw will fall into the opening slot of the clutch shaft, so that the reversing screw and the clutch shaft rotate synchronously, thus completing the reversing.

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

[0007] The purpose of this invention is to provide a door lock that can be quickly reversed, making the reversal process more convenient.

The clutch shaft has a first opening groove and a second opening groove. The first return spring drives the free-rotating pin to disengage from the opening groove, and the clutch motor drives the free-rotating pin to insert into the first opening groove or the second opening groove to engage the clutch shaft and the clutch disc. The handle is connected and fixed to the clutch disc. The clutch shaft has a limiting protrusion extending away from the center, and the clutch disc has a first mating protrusion and a second mating protrusion that cooperate with the limiting protrusion. The clutch shaft is provided with a square hole to accommodate the square shaft. When the square shaft disengages from the lock body, the clutch shaft can rotate from the right-open position where the limiting protrusion abuts against the first mating protrusion to the left-open position where it abuts against the second mating protrusion. When the limiting protrusion abuts against the first mating protrusion, the first opening groove corresponds to the position of the empty rotating pin. The lock body restricts the square shaft and the clutch shaft from rotating clockwise, thereby restricting the clutch disc and the handle from rotating clockwise. When the limiting protrusion abuts against the second mating protrusion, the second opening groove corresponds to the position of the empty rotating pin. The lock body restricts the square shaft and the clutch shaft from rotating counterclockwise, thereby restricting the clutch disc and the handle from rotating counterclockwise.

[0009] In one embodiment of the present invention, the clutch shaft has a connecting section that partially protrudes from the housing and a rotating section that is accommodated within the housing, the rotating section being provided with a limiting step that abuts against the housing.

[0010] In one embodiment of this utility model, the connecting segment is provided with an indicator mark, and the housing is provided with a first mating mark and a second mating mark that mate with the indicator mark. When the indicator mark points to the first mating mark, the limiting protrusion abuts against the first mating protrusion. When the indicator mark points to the second mating mark, the limiting protrusion abuts against the second mating protrusion.

[0011] In one embodiment of this utility model, the handle is provided with a mechanical lock cylinder, the mechanical lock cylinder is provided with a drive head, the clutch shaft and the drive head are directly provided with a clutch rod, a second return spring is provided between the clutch rod and the housing for driving the clutch rod to separate from the clutch shaft, the clutch shaft is provided with a clutch hole that engages with the clutch rod, the clutch rod is provided with a mating part that engages with the drive head, and the drive head causes the clutch rod to engage with the clutch shaft by rotating and pressing the mating part.

[0012] In one embodiment of this utility model, the drive head is a "V"-shaped protrusion, the mating part is a "V"-shaped recess, and the lock cylinder, the clutch rod, and the clutch shaft are arranged on the same axis.

[0013] In one embodiment of the present invention, a third return spring is provided between the handle and the housing, the third return spring being used to keep the handle in the initial position.

[0014] In one embodiment of this utility model, the door lock is further provided with a controller, a fingerprint sensor and a keypad connected to the controller, and the controller is connected to the clutch motor.

[0015] In one embodiment of this utility model, a through hole is provided at one end of the square shaft, and a pin hole corresponding to the through hole is provided on the outer peripheral surface of the connecting section, through which the connecting section passes.

[0016] In one embodiment of this utility model, the clutch hole is a square hole, and the handle is connected to a retaining spring for fixing the clutch disc.

[0017] In one embodiment of the present invention, the clutch rod is provided with a support step in the middle for supporting the second reset spring.

[0018] In this invention, when the square shaft is not inserted into the lock body, the clutch shaft can rotate from the right-open position where the limiting protrusion abuts against the first mating protrusion to the left-open position where it abuts against the second mating protrusion. When the limiting protrusion abuts against the first mating protrusion, the first opening groove corresponds to the position of the empty rotating pin. The lock body restricts the square shaft and the clutch shaft from rotating clockwise, thereby restricting the clutch disc and the handle from rotating clockwise. When the limiting protrusion abuts against the second mating protrusion, the second opening groove corresponds to the position of the empty rotating pin. The lock body restricts the square shaft and the clutch shaft from rotating counterclockwise, thereby restricting the clutch disc and the handle from rotating counterclockwise.
