[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] See also Figure 1-6 , the utility model provides a technical solution:

[0027] A refrigerator door integrated buckle lock modular lock assembly, comprising

[0028] The handle assembly 2 is arranged on the side where the door 11 contacts the refrigerator 1. A lock assembly 3 is provided on the top side of the handle assembly 2. A mounting seat 4 is installed on the inner side of the door 11. A mounting groove 47 is opened on one side of the mounting seat 4. The handle assembly 2 is installed in the inner cavity of the mounting groove 47. A lock catch 12 is provided on the inner side of the refrigerator 1. The lock assembly 3 and the lock catch 12 are used to achieve locking of the refrigerator 1 and the door 11;

[0029] The hand assembly 2 includes a fixed chamber 21, an inner cavity of the fixed chamber 21 is provided with a hand chamber 22, a top of the hand chamber 22 is provided with a linkage shaft 221, and the hand chamber 22 is movably connected to the fixed chamber 21 through the linkage shaft 221;

[0030] The lock assembly 3 includes a driving shaft 31, a transmission plate 32 is provided at one end of the driving shaft 31, and a lock head 33 is provided at one end of the transmission plate 32. When the lock head 33 is in the inner cavity of the lock buckle 12, the refrigerator 1 and the door 11 are in a locked state.

[0031] In this embodiment, please refer to Figure 4-5 The top of the linkage shaft 221 is provided with a main bevel gear 222, and the outside of the driving shaft 31 is provided with a secondary bevel gear 36. The outer edge of the secondary bevel gear 36 meshes with the outer edge of the main bevel gear 222. The other end of the driving shaft 31 is provided with a fixed cover 34. In this embodiment, when the box door 11 is opened, the hand bin 22 is buckled inwardly by external force, so that it rotates in the inner cavity of the fixed bin 21, thereby causing the linkage shaft 221 to drive the main bevel gear 222 to rotate. Through the rotation effect of the main bevel gear 222 and the secondary bevel gear 36, the secondary driving shaft 31 is rotated, and the transmission plate 32 is rotated downward, so that the lock head 33 is disengaged from the inner cavity of the lock buckle 12, and the box door 11 can be opened.

[0032] In this embodiment, please refer to Figure 4-5 , a return spring 23 is provided on one side of the inner cavity of the fixed chamber 21, and a spring spring 35 is provided on the inner cavity of the fixed cover 34. The spring spring 35 is fixedly connected to the outer side of one end of the secondary bevel gear 36, and the side of the lock head 33 in contact with the lock buckle 12 is set as an inclined surface. In this embodiment, when the hand chamber 22 is buckled inward, the return spring 23 is deformed by force, and when the active shaft 31 rotates, the spring spring 35 is deformed by force. When the force on the hand chamber 22 is stopped, the active shaft 31 is rotated under the elastic force of the return spring 23 and the spring spring 35. 1 rotates, so that the lock head 33 returns to its original position, and the box door 11 is directly closed at this time. Since the contact surface between the lock head 33 and the lock catch 12 is set as an inclined surface, when the box door 11 is closed, the lock head 33 is forced to move downward, and the spring spring 35 is again forced to deform. When the lock head 33 enters the inner cavity of the lock catch 12, under the action of the spring spring 35, the lock head 33 moves upward again and buckles into the inner cavity of the lock catch 12. Therefore, after the box door 11 is opened, there is no need to press the buckle compartment 22, and the box door 11 can be closed and locked by directly closing the box door 11.

[0033] In this embodiment, please refer to Figure 6, a movable warehouse 41 is provided on the inner side of the mounting groove 47, and a connecting block 42 is provided in the inner cavity of the movable warehouse 41. A second magnetic ring 43 is provided on one side of the connecting block 42. A rotating plate 45 connected by a rotating shaft is provided on one side of the mounting seat 4, and a first magnetic ring 46 is provided on one side of the rotating plate 45. The corresponding surfaces of the first magnetic ring 46 and the second magnetic ring 43 attract each other, and a connecting groove 211 corresponding to the connecting block 42 is provided on one side of the fixed warehouse 21. In this embodiment, after the rotating plate 45 is rotated by the rotating shaft, the first magnetic ring 46 and the second magnetic ring 43 correspond to each other, the first magnetic ring 46 is moved backward by the suction force of the second magnetic ring 43, thereby driving the connecting block 42 to disengage it from the inner cavity of the connecting groove 211, and the buckle assembly 2 and the lock assembly 3 can be removed from the mounting seat 4.

[0034] In this embodiment, please refer to Figure 6 The inner cavity of the movable chamber 41 is also provided with a spring 44, and the rotating plate 45 is made of magnetic shielding material. In this embodiment, by providing the spring 44, when the connecting block 42 moves backward, the second magnetic ring 43 is squeezed and deformed. When the rotating plate 45 is controlled to flip again, the rotating plate 45 is blocked between the second magnetic ring 43 and the first magnetic ring 46, so that the magnetic field between the second magnetic ring 43 and the first magnetic ring 46 disappears, and the spring 44 loses pressure and rebounds, so that the connecting block 42 returns to its original position.

[0035] Working principle of this utility model:

[0036] Step 1: When opening the door 11, the buckle compartment 22 is buckled inward by external force, so that the linkage shaft 221 is rotated by the force, and the main bevel gear 222 is driven to rotate by the linkage shaft 221. Since the outer edge of the main bevel gear 222 is meshed with the outer edge of the secondary bevel gear 36, the secondary bevel gear 36 is driven to rotate, and the secondary bevel gear 36 drives the driving shaft 31 to rotate, and the driving shaft 31 drives the transmission plate 32 to rotate downward, so that the lock head 33 gradually disengages from the inner cavity of the lock buckle 12, thereby disconnecting the refrigerator 1 from the door 11, and the door 11 can be opened;

[0037] The second magnetic ring 43 is rotated by the rotating shaft connected to the fixed cover 34 by external force, so that the rotating plate 45 rotates. After the rotating plate 45 is turned 180 degrees, the rotating plate 45 and the second magnetic ring 43 correspond to each other. Due to the mutual attraction between the corresponding surfaces of the rotating plate 45 and the second magnetic ring 43, the second magnetic ring 43 drives the connecting block 42 to move backward and squeezes the spring 44 to deform it. The connecting block 42 moves backward to disengage from the inner cavity of the connecting groove 211, thereby disconnecting the catch assembly 2 from the mounting seat 4, and the catch assembly 2 and the lock assembly 3 can be removed from the box door 11. During installation, the fixed compartment 21 is installed into the mounting groove 47 and the rotating plate 45 is rotated again so that the rotating plate 45 is blocked between the second magnetic ring 43 and the first magnetic ring 46. The rotating plate 45 shields the magnetic field, so that the attraction between the second magnetic ring 43 and the first magnetic ring 46 disappears, the spring 44 loses pressure and rebounds, and the connecting block 42 is re-placed into the inner cavity of the connecting groove 211 to complete the installation.
