The first handle passes through the mounting position of the second rotating member 101 and is connected to the second connecting member 105, the second handle passes through the frame of the lock body and is connected to the third connecting member 106, and the mounting position may be directly disposed on the second rotating member 101 or disposed on the structure connected to the second rotating member 101.

A first connecting piece 102 is installed at the lower end of the first rotating piece 100, the first connecting piece 102 is in transmission connection with a lock head assembly 103, the first connecting piece 102 is hinged to the lock body frame 200, and the first connecting piece 102 is in transmission connection with a square tongue 104 which is installed on the lock body frame 200 and moves back and forth on the lock body frame 200;

a second connecting piece 105 and a third connecting piece 106 are sequentially mounted at the lower end of the second rotating piece 101, the second connecting piece 105 and the third connecting piece 106 are respectively provided with a first mounting hole 107 and a second mounting hole 108 for mounting a first handle, and an isolation structure 109 for separating the first handle and the second handle is arranged between the first mounting hole 107 and the second mounting hole 108;

the second connecting piece 105 is connected with a deflector rod structure 110, the second connecting piece 105 and the deflector rod structure 110 are in intermittent transmission, the deflector rod structure 110 is connected with a latch bolt assembly 111 for opening and locking a door, one end of the deflector rod structure 110 is hinged to the lock body frame 200, and the deflector rod structure is used for retracting the latch bolt assembly 111 into the lock body frame 200.

Specifically, the first handle rotates to drive the second connecting member 105 to rotate, and the second connecting member 105 triggers the latch assembly 111 to retract inwards through the shift lever structure 110, so as to achieve the effect of opening the door.

In a preferred embodiment, the lever structure 110 is provided with a mounting groove 112 for mounting the second connecting member 105, and one end of the lever structure 110 hinged to the lock body frame 200 is provided with a hinged torsion spring 113. The mounting slot 112 is used for the lever structure 110 to be locked with the isolation structure 109, so that the lever structure 110 is driven to rotate when the second rotating member 101 rotates.

In a possible embodiment, one end of the second connecting member 105 connected to the shifter lever structure 110 is an arc-shaped structure 114, and the two sides of the arc-shaped structure 114 of the second connecting member 105 are provided with protruding structures 115, and the size of the protruding structures 115 is larger than the inner diameter of the arc-shaped structure 114.

When the portions of the lever structure 110 located at the two sides of the mounting groove 112 abut against the protruding structures 115, a distance is provided between the protruding structures 115 of the second connecting member 105 located at the two sides of the arc-shaped structure 114 and the portions of the lever structure 110 located at the two sides of the mounting groove 112, wherein the distance can refer to the structures shown in fig. 3 and 4, that is, the second connecting member 105 does not contact the lever structure 110.

When the portions of the lever structure 110 located at the two sides of the mounting groove 112 are separated from the protrusions 115, the protrusions 115 of the second connecting member 105 located at the two sides of the arc-shaped structure 114 are in contact with the portions of the lever structure 110 located at the two sides of the mounting groove 112. At this time, the rotation position of the lever structure 110 is restricted so that the lever structure 110 is driven to rotate by the second link 105 at the next time.

Specifically, when one end of the protrusion 115 abuts against a plane of the lever structure 110 on one side of the mounting slot 112, the protrusion 115 drives the lever structure 110 to rotate, and when there is a gap between the protrusion 115 and the plane of the lever structure 110 on one side of the mounting slot 112, the rotation does not trigger the lever structure 110 to rotate, which corresponds to the above-mentioned intermittent transmission.

In one possible embodiment, a return spring is provided between the latch bolt assembly 111 and the inner side of the lock body frame 200, that is, when the shifter mechanism 110 compresses the latch bolt assembly 111 for locking the door into the lock body frame 200 to achieve the effect of opening the door, if the shifter mechanism 110 loses the torque of rotation (the user does not rotate the handle any more), the latch bolt assembly 111 (in which the latch bolt assembly 111 includes the latch bolt) automatically returns to the door-locking state (i.e., the latch bolt pops out).

In a preferred embodiment, the first link 102 is connected to a linkage fork 116 that moves synchronously with the tongue 104, and the first link 102 is provided with an abutting portion (a structure such as a boss that can be understood as being located below the first rotation 100), and the linkage fork 116 abuts against the abutting portion.

Specifically, after the handle lock transmission mechanism of the present embodiment closes the door, the insertion-preventing tongue 124 retracts to push the insertion-preventing hook piece 125 to move, and at this time, the two-hole spring 126 pulls the insertion-preventing plate 127, the contact surface in the insertion-preventing plate 127 contacts with the contact surface in the latch bolt assembly 111, and the latch bolt assembly cannot retract, so that the insertion-preventing function is realized.

Because the handle lock opening and closing transmission mechanism is provided with the anti-inserting plate 127, the anti-inserting function can be removed after the anti-inserting plate 127 rotates. The interlock fork 116 limits the rotation of the anti-insertion plate 127 so that the interlock fork 116 acts to disengage the anti-insertion function when the handle is opened, and the interlock fork 116 performs the anti-insertion function when the abutment portion drives the interlock fork 116 to rotate.

In an alternative embodiment, the first rotating member 100 is provided with at least four engaging tooth grooves 118, and the second rotating member 101 is provided with four engaging teeth 119 corresponding to the engaging tooth grooves 118, and the engaging tooth grooves 118 are engaged with the engaging teeth 119.

In a preferred embodiment, the second connecting member 105 is connected to a clutch 121 for controlling the position of the latch bolt assembly 111, and the second connecting member 105 is provided with a contact portion 123 abutting against a clutch plate 122 of the clutch 121.

The clutch 121 is used for controlling the forward and backward movement of the latch bolt assembly 111 (of the latch bolt), and may be controlled by a moving path of the latch bolt assembly 111 (of the latch bolt) provided with a switch sensor.

An output shaft of a first handle (not shown in the figure) is mounted in the first mounting hole 107; the first handle is lifted and rotated to drive the second connecting piece 105 to rotate, the mounting groove of the second connecting piece 105 is matched with the connecting bulge in the second rotating piece 101 to rotate the first rotating piece 100, and the connecting lug boss of the first rotating piece 100 moves in the sliding guide groove of the square tongue 104 to eject the square tongue 104. Wherein, when the first handle is pressed down, the square tongue 104 retracts into the lock body frame 200.

When the output shaft of the second handle (not shown) is mounted in the second mounting hole 108 of the third connecting member 106; the third connecting member 106 is rotated by lifting up the rotating handle shaft. The third connecting member 106 rotates the first rotating member 100 in cooperation with the connecting projection of the second rotating member 101, and the connecting projection of the first rotating member 100 moves in the sliding guide groove of the tongue 104 to eject the tongue 104. Wherein, when the second handle is pressed, the square bolt 104 retracts into the lock body frame 200.
