Description

Technical Field

[0001] The utility model relates to the technical field of door locks, and more specifically, to a minimalist door lock. Background Art

[0002] A door lock is a commonly used door protection device to prevent illegal intrusion. Among them, an ecological door lock is a minimalist door lock in which the door lock accessories are built into the handle; usually, the locking mechanism for locking the outer handle is built into the outer handle, and the anti-locking mechanism is built into the inner handle;

[0003] For example, the Chinese utility model patent with application number CN202122405727.6 discloses a rack-type anti-locking mechanism of a door lock, including an inner door handle and an outer door handle, wherein the inner door handle is rotatably set on the inner panel, and the outer door handle is rotatably set on the outer panel, wherein the inner door handle and the outer door handle are connected by a square shaft; the inner door handle is equipped with an anti-locking mechanism, and the outer door handle is equipped with a locking mechanism, and the anti-locking mechanism is linked to the locking mechanism through a rotating rod; the anti-locking mechanism includes an anti-locking tooth frame slidably set on the inner door handle and an anti-locking gear connected to the rotating rod, and the anti-locking tooth frame The inner wall is provided with an anti-lock rack, wherein the anti-lock gear is placed in the anti-lock tooth frame and meshes with the anti-lock rack in the anti-lock tooth frame; only the anti-lock tooth frame needs to be pushed to slide the door handle inside, and the anti-lock tooth frame drives the rotating rod to rotate by driving the anti-lock gear, and the locking mechanism is driven by the rotating rod, so that the locking mechanism restricts the rotation of the door handle outside; the door lock is driven by the cooperation of the rack and the gear, and it is easy to get stuck during use, which makes the anti-locking or unlocking operation of the door lock not smooth; at the same time, when the handle is turned to unlock, the handle seat will rotate with the handle, making the door lock opening more cumbersome and not light.

DETAILED DESCRIPTION

[0027] See attached Figures 1 to 6 The present invention further describes a minimalist door lock in detail.

[0028] A minimalist door lock, comprising an inner base 1 and an outer base 2, wherein the inner base 1 is provided with an inner handle 3, and the outer base 2 is provided with an outer handle 4, wherein the inner handle 3 is linked with the outer handle 4 through a square shaft 9; the inner handle 3 comprises an inner handle seat 31 and an inner handle body 32 which are separately arranged, and the inner handle seat 31 is fixed on the inner base 1; the inner handle body 32 is rotatably arranged in the inner handle seat 31, and is provided with an anti-locking mechanism 5;

[0029] The outer handle 4 includes an outer handle seat 41 and an outer handle body 42 which are separately arranged; the outer handle seat 41 is fixed on the outer base 2; the outer handle body 42 is rotatably arranged on the outer handle seat 41, and is provided with a locking mechanism 6, and the locking mechanism 6 is linked with the anti-locking mechanism 5 through a linkage rod 7;

[0030] The anti-locking mechanism 5 includes a rotating member 51 rotatably disposed in the inner handle body 32 and a driving assembly 52 for driving the rotating member 51. The rotating member 51 is connected to the linkage rod 7, and a thread groove 5121 is formed on its outer side wall.

[0031] The driving assembly 52 includes an unlocking member 521 and a toggle member 522. The unlocking member 521 is provided with an unlocking head 5211 matched with the thread groove 5121 on the inner side, and a linkage block 5212 is provided on the outer side. The toggle member 522 is provided with linkage grooves 5221 matched with the linkage block 5212 along the left and right ends of the inner side, and the toggle block 5222 on the outer side passes through the inner handle seat 31.

[0032] When the door lock is reversed, by pressing down the toggle block 5222, the toggle member 522 drives the unlocking member 521 to move downward through the linkage block 5212, and the unlocking head 5211 of the unlocking member 521 drives the rotating member 51 to rotate by pressing down the thread groove 5121 of the rotating member 51, and the rotating member 51 drives the linkage rod 7 to rotate, so that the locking mechanism 6 locks the outer handle body 42 to the outer handle seat 41; so that people outside the door cannot perform the unlocking operation by pressing down the outer handle 4, and the reverse locking function of the door lock is realized; in this process, the unlocking member 521 can smoothly drive the rotating member 51 to rotate, so that the transmission of the reverse locking mechanism 5 is smoother, and the jamming phenomenon of the door lock during reverse locking or unlocking operation is avoided, so that the product has a good user experience;

[0033] When the door lock is in the unlocked state and the unlocking operation is performed, the inner handle body 32 is pressed down, and the inner handle body 32 will drive the unlocking piece 521 to rotate. During this process, the linkage block 5212 slides along the linkage groove 5221; that is, during the unlocking operation, the inner handle body 32 rotates independently relative to the inner handle seat 31; similarly, when the outer handle body 42 is operated to perform the unlocking operation, the outer handle body 42 also rotates independently relative to the outer handle seat 41, making the unlocking operation of the door lock easier.

[0034] For ease of production, the rotating member 51 includes a rotating member body 511 and a rotating member shell 512 . The rotating member shell 512 is fixed to the rotating member body 511 . The thread groove 5121 is opened on the side wall of the rotating member shell 512 , thereby reducing the difficulty of opening the thread groove 5121 on the rotating member 511 .

[0035] A toggle window 311 is provided on the side wall of the inner handle seat 31, and the toggle block 5222 of the toggle member 522 passes through the toggle window 311; a first guide member 312 is provided in the inner handle seat 31, and the toggle member 522 moves under the guidance of the first guide member 312; a sliding groove 321 for the unlocking member 521 to slide up and down is provided on the side wall of the handle head of the inner handle body 32, and a second guide member 322 is provided in the sliding groove 321, and the second guide member 322 is provided with a guide groove 3221 for guiding the movement of the unlocking head 5211; so that the toggle member 522 can move more smoothly under the guidance of the first guide member 312, making the unlocking or locking operation more labor-saving.

[0036] The locking mechanism 6 includes an outer handle head 61 on the outer handle body 42, a locking cam rotatably arranged in the outer handle head 61, and a locking column matched with the locking cam; the locking cam is provided with two cam surfaces adapted to the locking column, and the cam surfaces can be used to accommodate the locking column. One end of the locking cam is connected to the linkage rod 7, and the other end of the locking cam is connected to the lock core 8; the linkage rod 7 drives the locking cam to rotate, and the locking cam squeezes the locking column outward, so that a part of the locking column passes through the locking hole of the outer handle head 61 and is placed in the locking groove 411 of the outer handle seat 41, and the outer handle body 42 is firmly locked on the outer handle seat 41, so that people cannot achieve the unlocking operation by pressing down the outer handle 4 or the inner handle 3; when unlocking, the person outside the door can open the lock core 8 with a key to drive the locking cam to rotate, or the person inside the door can push the toggle member 522 back to drive the locking cam to rotate through the linkage rod 7, so that the locking column is received in the cam surface, so that the locking mechanism 6 releases the lock on the outer handle 4 and achieves unlocking; the unlocking operation can be performed by pressing down the outer handle 4 or the inner handle 3.
