The lock has the advantages that the existing lock is complex in structure and unreliable in transmission, the turning tongue can freely rotate after unlocking the limiting piece through the arrangement of the turning tongue, door opening and closing are facilitated, the turning tongue can achieve a door locking function through the locking of the limiting piece, the structure is simple, the opening force is small, and the adaptation range is wide. The invention also has the advantages of simple structure, convenient assembly, reliable action, long service life and the like. Specifically, the stopper has a third position where the first elastic member cannot return the stopper when the stopper is held. Specifically, the operation may be performed by a mechanical operation mechanism or an electric operation mechanism, and the electric operation mechanism may be performed by a button (control) to control the operation of the power source through a circuit board. The mechanical operating mechanism can be realized through the cooperation of the operating piece and the holding part, or the holding piece limiting and limiting piece is additionally arranged, for example, a button or a bolt is arranged, when the limiting piece is required to be kept at a normally open (third position), the button bolt is pressed (or rotated), and the limiting and limiting piece is reset in a mechanical interlocking mode. More specifically, the limiting piece 5 is hinged on the shell 1, the shell 1 is provided with a push rod 15 and a fourth elastic piece 16, and the fourth elastic piece 16 is propped against the limiting piece 5 through the push rod 15 and is matched with the mechanical operating mechanism 4 so that the limiting piece 5 is kept at the second position. The invention also provides a mode of matching the ejector rod with the limiting piece, and the fourth elastic piece can additionally provide restoring force when the limiting piece is positioned at the second position, so that the limiting piece tends to the first position, and the turning tongue is reliably interlocked. When the operating piece rotates to exceed the holding part, the ejector rod pushes the limiting piece at the fourth elastic position, the operating block of the operating piece pushes the other side of the limiting piece, and the limiting piece is hinged to the shell at the end part, so that the ejector rod and the operating block are mutually matched at the moment to enable the limiting piece to be clamped, and the limiting piece is prevented from resetting. At the moment, the fourth elastic piece provides pushing force through the ejector rod and is mainly used for generating larger friction force between the limiting piece and the operation block, so that the operation piece is unlocked due to the fact that the operation piece or the door shakes in the using process of the limiting piece at the third position, the product interlocking is convenient and reliable, and the operation piece and the limiting piece are prevented from resetting. When the limiting piece is positioned at the first position, the turning tongue is turned over and limited by the limiting piece, and can not be opened, and can only act through a mechanical operating mechanism or an electric operating mechanism, and the door is locked by the similar inclined tongue. When the mechanical operating mechanism or the electric operating mechanism acts, the limiting piece is unlocked, and the door can be opened at the moment. When the limiting piece is in the third position, the door is opened and closed not controlled by the turning tongue, the door can be pushed open only by blocking the left and right sides without operation, the door can be opened conveniently without operating the handle or the operating piece, the door can be opened, time and labor are saved, and the operation is simple.

The turning tongue 2 is provided with a limiting groove 21, the limiting piece 5 is provided with a limiting part 51, the limiting part 51 is clamped into the limiting groove 21 when the limiting piece 5 is positioned at the first position and used for turning and limiting the turning tongue 2, and the turning tongue 2 is in sliding fit with the limiting part 51 when the limiting piece 5 is positioned at the first position. The structure can reliably interlock and turn over the turnup tongue when the limiting piece is positioned at the first position, and the turnup tongue can freely turn over when the limiting piece is positioned at the second position, so that the door can be conveniently opened by adopting smaller force (particularly when the motor is used for opening the door), and the door can be opened without operating the operating piece when the limiting piece is positioned at the third position. Compared with the mode of adopting the inclined tongue, under the conditions of heavier door, tight sealing rubber strip, house or door displacement and the like, the motor can not well drive the inclined tongue to open, the opening and closing are more laborious, the turning tongue opening stroke is small, and the required power is small, so that the structure is simple when the inner door is used, the transmission is convenient, the operation is reliable, and the energy consumption is small.

The mechanical operating mechanism 4 comprises an operating piece 41, an operating block 411 is arranged on the operating piece 41, a first transmission part 52 matched with the operating block 411 is arranged on the limiting piece 5, and the operating block 411 drives the limiting piece 5 to move to unlock the turning tongue 2 through rotation. Specifically, the casing 1 is provided with a second elastic member 12 for resetting the operating member 41, the first transmission portion 52 is provided with a holding block 53, and the operating member 41 passes over the holding block 53 and is limited by the holding block 53 so that the limiting member 5 is held in the second position. More specifically, the operating member 41 is provided with a restoring portion 412 that facilitates the second elastic member 12 to provide elastic force and a holding portion 413 that disables the second elastic member 12, and two elastic legs of the two second elastic members 12 are disposed outside the restoring portion 412. Specifically, the operating member may be connected to the handle or may be in an integral structure with the handle, and the operating member or the handle may cause the operating block to act, thereby controlling the movement of the stopper. Of course, in the actual production process, the operating piece can be provided with a key unlocking mechanism, the operating piece is driven to rotate by the rotation of the key so as to control the position of the limiting piece, the operating piece can be prevented from resetting when the operating piece is kept at the block, and the operating piece can also be prevented from resetting, so that the limiting piece is in a third position.

The shell 1 in be equipped with electric operating mechanism 3, electric operating mechanism 3 link to each other with locating part 5 and be used for driving locating part 5 action, electric operating mechanism 3 include power supply 31, drive assembly 32 and plectrum 33, power supply 31 be connected and be used for driving plectrum 33 rotation through drive assembly 32 and plectrum 33, locating part 5 on be equipped with the second drive portion 54 with plectrum 33 looks adaptation. The structure can reliably drive the limiting piece to rotate so as to unlock the turning tongue, specifically, in order to facilitate convenient operation and adapt to the operation habit of a user, two first transmission parts matched with the operation piece are symmetrically arranged, and only one second transmission part is arranged, so that the cost is reduced.

The transmission assembly 32 comprises a driving wheel 321 and a driving wheel 322, the driving wheel 321 and the driving wheel 322 are mutually meshed, the driving wheel 322 is mutually matched with the plectrum 33 to drive the plectrum 33 to rotate, and the plectrum 33 is provided with a driving piece 34 for driving the limiting piece 5 to move.
