Description
Technical Field
The invention relates to the field of locks, in particular to a lock mechanism with a reset function and a left-right reversing function.
Background
The lock comprises a panel, a lock tongue arranged in the panel, a shifting fork component linked with the lock tongue and a handle arranged on the panel for a user to pull and drive the lock tongue to extend or retract from the panel, wherein the lock tongue generally comprises an oblique lock tongue, a square lock tongue and a safety tongue, and the handle is called an inner handle or an outer handle according to the positions inside and outside a door. The inner and outer handles are respectively fixedly connected with an inner and outer square shaft, and when the inner and outer square shafts rotate, the shifting fork component of the lock is driven to rotate and at least comprises a middle shifting fork, and the middle shifting fork controls the retraction and extension of an inclined lock tongue of the lock. Normally, when a user is in the door, the inclined lock tongue can be opened by pulling the inner handle; when a user is out of a door, the mechanical lock needs to be inserted with a key to enable the shifting fork assembly to be linked with the inclined lock tongue to be retracted, the electronic lock needs to input keys such as fingerprints and digital codes to drive the shifting fork assembly to be linked with the lock tongue to be retracted, and when no key or the key is available, the outer handle can only be in an idle state and cannot enable the inclined lock tongue to be retracted.
The common direction of opening the door in life is to opening the door to the right, so most of the electronic locks on the market at present are to locks to the right, but there are also some users to open the door to the left, the quantity of the target users to open the door to the left is difficult to count in the factory when producing, therefore result that the yield of the left electronic lock is insufficient or the stock is excessive is easy to cause, therefore, the electronic locks which can realize the left-right reversing are needed, the demands of a large number of users to the right electronic locks are met, and the demands of a small number of users who need to open the locks to the left are also considered. After the lock is used for a long time, the condition that the handle is hung down and the shifting fork cannot be linked occurs because the handle and the shifting fork are not reset in place, so that a user cannot open the door.
Disclosure of Invention
The technical problem to be solved by the invention is to provide the lockset mechanism with the reset function and the left-right reversing function, which has the advantages of simple structure and convenience in installation.
In order to solve the technical problems, the invention is realized by the following technical scheme: the left-right reversing lock mechanism comprises a shifting fork assembly for linking the extension and retraction of a lock tongue, wherein the shifting fork assembly comprises a middle shifting fork, a first shifting fork and a second shifting fork are respectively arranged on two sides of the middle shifting fork, a square shaft is arranged among the first shifting fork, the middle shifting fork and the second shifting fork, and the square shaft comprises an inner square shaft and an outer square shaft which are coaxially arranged and can be inserted and pulled; the lock mechanism is in a first state, when the lock mechanism is in the first state, the inner square shaft is inserted into the first shifting fork and the middle shifting fork and is in circumferential linkage with the first shifting fork and the middle shifting fork, and the outer square shaft is inserted into the second shifting fork and is in circumferential linkage with the second shifting fork; when the lockset mechanism is in a second state, the inner square shaft is inserted into the second shifting fork and the middle shifting fork and is in circumferential linkage with the second shifting fork and the middle shifting fork, and the outer square shaft is inserted into the first shifting fork and is in circumferential linkage with the first shifting fork.
Through adopting above-mentioned technical scheme, when first shift fork and well shift fork are inserted and are established on the interior square shaft, interior square shaft one side is as the direction in the door, and the second shift fork is inserted and is established on the outside square shaft, and when outside square shaft one side was as the direction outside the door, the tool to lock is in first state, and the tool to lock is left to opening the door tool to lock when first state, thereby the user rotates interior square shaft in the door and thereby the rotatory realization of shift fork circumference unblanks in the linkage, and the user can only rotate the second shift fork outside the door, and so second lug can only rotate the user can't unblank in the spout cavity with well shift fork non-linkage under the first state. When the user exchanges interior square shaft and outer square shaft back, the tool to lock is in the second state, one side that originally is in the door outside direction becomes the door inside direction, the tool to lock becomes right direction tool to lock that opens the door, interior square shaft inserts and establishes in well shift fork and second shift fork this moment, outer square shaft inserts and establishes in first shift fork, thereby the user rotates interior square shaft in the door direction and links well shift fork circumference rotation and realize unblanking, the user can only rotate first shift fork outside the door, and first shift fork and well shift fork are not linked under the second state so first lug can only be at the hollow unable unblanking of turning user of spout.
