[0044] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0045] As shown in the figure, a two-way controlled lock body comprises a housing 1, a square tongue 14, a lock tongue 7, a first transmission mechanism driving the square tongue 14 to move linearly, and a second transmission mechanism driving the lock tongue 7 to move linearly. An operating mechanism for linking the first transmission mechanism and the second transmission mechanism is also provided in the housing 1, and the operating mechanism comprises:

[0047] A square shaft, which passes through the housing 1 and is linked to the rotating assembly;

[0048] The outer circumference of the rotating assembly is provided with a plurality of shifting blocks extending radially outward and having different heights. The rotating assembly has a first action of being driven by the square shaft to rotate clockwise and driving the lock tongue 7 and the square tongue 14 to unlock at the same time through the second transmission mechanism and the first transmission mechanism, and a second action of being driven by the square shaft to rotate counterclockwise and driving the square tongue 14 to lock through the first transmission mechanism. In this technical solution, whether the lock is located on the left or right side of the door, there is no need to change the lock body, and the direction of the lock tongue can be changed by adjusting the direction of the lock tongue. In addition, the door handle rotates to control the first hollow column and the second hollow column or the second hollow column and the third hollow column to complete the clockwise rotation and unlock the lock tongue and the square tongue at the same time, and rotates counterclockwise to drive only the first control ring to push the square tongue out to complete the locking action. The door handle outside only controls the fourth control ring or the first control ring and only drives the lock tongue, which is easy to operate. Compared with the prior art, there is no need to install a square tongue drive separately, and there is no distinction between left and right door locks. It has a wide applicability and is faster and more convenient to install.

[0049] The front end of the housing 1 is provided with a gusset plate 2;

[0050] The rotating assembly comprises:

[0051] The first hollow column 12, the second hollow column 37 and the third hollow column 38 are stacked in sequence from top to bottom;

[0052] A first control ring 33, which is sleeved on the outer circumference of the first hollow column 12 and is linked to the first hollow column 12;

[0053] The second control ring 11 and the third control ring 9 are sequentially sleeved on the outer circumference of the second hollow column 37 from top to bottom and are linked and connected;

[0054] A fourth control ring 34, which is sleeved on the outer circumference of the third hollow column 38 and is linked to the third hollow column 38;

[0055] The first hollow column 12, the second hollow column 37 and the third hollow column 38 are coaxially arranged and are all hexagonal prisms; the inner holes of the first control ring 33, the second control ring 11, the third control ring 9 and the fourth control ring 34 are provided with a plurality of avoidance grooves 41 for the first hollow column 12, the second hollow column 37 and the third hollow column 38 to rotate at appropriate angles. The square shaft is inserted into the first hollow column 12, the second hollow column 37 and the third hollow column 38, and twisting the square shaft will drive the rotating assembly to rotate as a whole.

[0056] The lower surface of the first hollow column 12 and the upper surface of the third hollow column 38 are both provided with positioning grooves 42, and the upper and lower surfaces of the second hollow column 37 are provided with positioning columns 43 adapted to the positioning grooves 42, and the positioning columns are cylindrical. The first hollow column 12 and the third hollow column 38 cooperate to clamp the second hollow column 37 so that the three can achieve relative rotation.

[0057] The dial block comprises:

[0058] A first shifting block 35, which is arranged on the outer circumference of the first control ring 33 and faces the second transmission mechanism;

[0059] A second shifting block 30, which is arranged on the outer circumference of the second control ring 11 and faces the first transmission mechanism;

[0060] A third shift block 39, which is arranged on the outer circumference of the third control ring 9 and faces the first transmission mechanism and has an angle with the second shift block 30;

[0061] A fourth shift block 28, which is disposed on the outer circumference of the fourth control ring 34 and is in the same direction as the first shift block 35;

[0062] The fifth shift block 29 is arranged on the outer circumference of the third control ring 9 and faces the first transmission mechanism; the first shift block is driven by the first hollow column to swing, and the fourth shift block is driven by the third hollow column to swing, so the first shift block or the fourth shift block can control the movement of the lock tongue through the second transmission assembly.

[0063] The outer circumference of the second control ring 11 is also provided with a limit block 31 extending radially outward. The first shift block or the second shift block pushes the connecting rod and the lock tongue backward through the limit rear plate. The limit block will rotate upward until it touches the limit front plate, thereby driving the lock tongue to stop moving.

[0064] The second transmission mechanism comprises:

[0065] A connecting rod 25, one end of which is fixedly connected to the locking tongue 7 and the other end of which is slidably engaged with the housing 1;

[0066] A limiting front plate 24 and a limiting rear plate 26 are arranged at intervals and sleeved on the connecting rod 25;

[0067] A first elastic member 27, which is sleeved on the connecting rod 25 and has two ends respectively abutting against the limiting front plate 24 and the locking tongue 7;

[0068] The first shift block 35 and the fourth shift block 28 are clamped between the limit front plate 24 and the limit rear plate 26. The limit front plate is fixedly connected to the shell and slidably cooperates with the connecting rod. The limit rear plate is fixedly connected to the connecting rod. The limit rear plate serves as a force point. After being subjected to the force of the first shift block 35 and the fourth shift block 28, the lock tongue will be driven to move backward. When the force is cancelled, the first elastic member will provide an elastic preload force for resetting the lock tongue.

[0069] The first transmission mechanism comprises:

[0070] A square tongue operating plate 5, one end of which is fixedly connected to the square tongue 14 and the other end of which is slidably matched with the housing 1;

[0071] The first transmission member 6 and the second transmission member 44 are symmetrically arranged and movably mounted on both sides of the tongue operating plate 5;

[0072] The square tongue operating plate 5 is provided with an inclined first slide groove 15 and a transversely arranged second slide groove 16; a first slide shaft 18 connected in series with the first transmission member 6 and the second transmission member 44 and slidingly matched with the first slide groove 15 and a second slide shaft 45 connected in series with the second slide groove 16 are provided between the first transmission member 6 and the second transmission member 44;

[0073] The first transmission member 6 is provided with a first force block 19 corresponding to and in contact with the second shift block 30; the second transmission member 44 is provided with a second force block 40 corresponding to and in contact with the fifth shift block 29. The second sliding shaft is fixedly mounted on the shell, so the first transmission member and the second transmission member synchronously perform a swinging motion around the second sliding shaft. When the first transmission member swings downward, the first sliding shaft moves along the first sliding groove, thereby driving the square tongue operating plate to move horizontally, thereby realizing the action of retracting the square tongue into the shell. When the first transmission member swings upward, it will drive the square tongue operating plate to move horizontally, thereby realizing the action of extending the square tongue out of the shell.

[0074] A fixed plate 21 is provided on the inner wall of the shell 1, and a movable plate 22 that movably connects the second transmission member 44 and the fixed plate 21 is provided between the two. A sliding track 20 is provided on the second transmission member 44, and a sliding groove 48 that slides with the sliding track 20 is provided at one end of the movable plate 22. The other end of the movable plate 22 passes through the fixed plate 21, and a second elastic member 23 that contacts the movable plate 22 and the fixed plate 21 is provided between the two. The second elastic member provides elastic pre-tightening force for the movement of the first transmission member and the second transmission member in the first sliding groove so that they can move into place.

[0075] The square shaft comprises:

[0076] The main shaft body includes a first shaft portion 32 located at the upper end and in a square shape, a second shaft portion 49 located in the middle section and in a cylindrical shape, and a third shaft portion 50 located at the lower end and in a square shape;

[0077] The secondary shaft body 10 is sleeved on the second shaft portion 49 and rotatably matched therewith.

[0078] The utility model is a two-way controlled lock body. When in use, the entire shell 1 is installed in the door panel. At the same time, the secondary shaft body 10 is linked to the external handle. At the same time, one end of the secondary shaft body 10 is inserted and installed in the third hollow column 38, and drives the fourth control ring 34 to rotate. The locking tongue 7 is pulled back by the limiting rear plate 26 to unlock. The first shaft portion 32 is linked to the handle in the door. The first shaft portion 32 is inserted in the square holes of the first hollow column 12 and the second hollow column 37. When the first shaft portion 32 rotates clockwise, the third control ring 33 and the second control ring 11 are driven to rotate. The first shift block 35 is used to pull the locking tongue 7 back. At the same time, the second shift block 30 drives the first force block 19 to pull the square tongue back to complete unlocking. When the first shaft portion 32 rotates counterclockwise, the third control ring is driven to reverse. The fifth shift block 29 is used to drive the second force block 40 to push the square tongue out to complete the locking action. The reason why such segmented control can be achieved is that the inner rings of all control rings are concave-convex arc edges, that is, they are provided with avoidance grooves 41, and the outer wall of the hollow column is hexagonal. When the hollow column drives the control ring, it has a 45-degree rotation space. Therefore, when the square shaft rotates clockwise, it can drive the second control ring 11 and the first control ring to rotate, but does not drive the third control ring 9. When the square shaft rotates counterclockwise, it only drives the third control ring to rotate, but does not drive the second control ring 11 and the first control ring to rotate, thus realizing forward and reverse bidirectional segmented operation. If the door lock is turned over, the principle is the same.

[0079] For example, the fourth control ring 34 moves the limiting rear plate 26 to one side through the fourth shift block 28 on one side, thereby making the limiting rear plate 26 drive the connecting rod 25 to move to one side in the limiting front plate 24, so that the connecting rod 25 drives the lock tongue to move, and when the first shaft portion 32 rotates clockwise, it can drive the first hollow column 12 to rotate clockwise, and make the outer wall flange of the first hollow column 12 rotate in the avoidance groove of the inner wall of the first control ring to drive the first control ring to rotate clockwise, so that the first control ring drives the first shift block 35 to move the limiting rear plate 26 to one side, thereby driving the connecting rod 25 to retract the lock tongue, and at the same time, the second control ring 11 squeezes the fixed ring 20 to one side through the second shift block 30, so that one end of the movable plate 22 moves from the first The force is released in the groove near the fixed ring 20 at the rear end of the transmission member 6, and then rebounds through the second elastic member 23 on the movable plate 22, so that the sliding shaft 18 at the front end of the first transmission member 6 slides to one side of the first guide groove 15, so that the first transmission member 6 also slides backward on the fixed shaft 17 through the second guide groove 16, so that the first transmission member 6 retracts the square tongue 14 into the first fixed seat 3 through the connecting plate 13. When the first shaft portion 32 rotates counterclockwise, the flange of the outer wall of the hollow column 37 squeezes on the straight edge of the inner wall of the third control ring to drive the third control ring to rotate. At the same time, the flange of the outer wall of the hollow column 37 slides in the arc groove of the inner wall of the second control ring 11 without driving the second control ring 11 to rotate, so that the third control ring 11 can rotate. The fifth shift block 29 on one side of the ring 9 drives the second force-bearing block 40 to be squeezed backward, so that the first transmission member 6 rotates with the fixed shaft 17 as the axis, so that the sliding shaft 18 at the front end of the first transmission member 6 moves in the first guide groove 15, and the first guide groove 15 is squeezed to one side in the sliding shaft 18 to move the first transmission member 6 to the front end, so that the first transmission member 6 moves the square tongue 14 out of the first fixed seat 3 through the connecting plate 13, and the first transmission member 6 is limited in the sliding track 20 at the rear end of the first transmission member 6 by the sliding groove 48 of the movable plate 22. Similarly, since the door is divided into left and right, there is no need to change the lock body when changing sides, and the direction of the lock tongue is directly adjusted. The second hollow column 37 and the third hollow column 38 are sleeved on the first shaft portion 3 2, and as mentioned above, the first hollow column 12 and the second hollow column 37 are sleeved on the first shaft portion 32. When the first shaft portion 32 rotates clockwise, the first control ring 33, the second control ring 11, and the third control ring 9 are driven to rotate the first shift block 35 clockwise to pull the lock tongue back, and the second shift block 30 presses against the first force block 19 to retract the square tongue, completing the unlocking and retraction of the lock tongue and the square tongue. When the first shaft portion 32 rotates counterclockwise, the third control ring is driven to rotate counterclockwise, and the fifth shift block 29 pulls the second force block 40 to push the square tongue out. The rotation of the secondary shaft body 10 only drives the fourth control ring 34, and the fourth shift block 28 pulls the lock tongue back to unlock. Among them, the limit block 31 and the third shift block 39 have a reverse limit function and have no other functions.
