[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example

[0030] See Figures 1 to 5 As shown:

[0031] The present invention provides a refrigerator door lock that facilitates opening and closing, comprising: a housing 1, a button 2, a locking block 4, a locking assembly, and an adjustment assembly.

[0032] The back of the outer casing 1 is provided with bolt holes 9 for connecting to the side wall of the refrigerator, and the front is provided with a fixing iron plate 6. The outer casing 1 is installed in the side wall of the refrigerator through the bolt holes 9 and the fixing iron plate 6, while the clip 4 is installed on the refrigerator door.

[0033] Both the locking assembly and the adjusting assembly are installed in the housing 1, and the locking block 4 engages with the locking assembly. The button 2 is located outside the housing 1 and is connected to the locking assembly. The adjusting assembly is connected to the locking assembly and is used to adjust the position of the locking assembly, thereby allowing the locking block 4 to better engage with the locking assembly.

[0034] In actual use, the operator can release the engagement between the latch 4 and the locking assembly by pressing button 2, thus enabling one-button opening of the refrigerator door. This design not only ensures a secure lock between the refrigerator door and the side wall of the refrigerator, but also features a simple structure and ease of use.

[0035] The locking assembly mainly consists of a rotating part and a snap-fit ​​part.

[0036] In actual use, the rotating part is slidably connected to the locking block 4, and the rotating part can rotate around its center under the push of an external force. The locking part is locked to the rotating part, and the locking part is fixedly connected to the button 2. The rotating part is fixed on the adjustment component, and the adjustment component adjusts the position of the rotating part so that the center of the rotating part coincides with the center point of the locking block 4.

[0037] In actual use, as the latch 4 moves closer to the side wall of the refrigerator along with the refrigerator door, the latch 4 presses against the rotating part, causing the rotating part to rotate until the rotating part engages with the latching part, thus locking the latch 4 in the rotating part.

[0038] This design allows the refrigerator door to automatically lock with the side wall of the refrigerator, eliminating the need for a key. The structure is simple and the operation is convenient.

[0039] The rotating part mainly consists of a rotating block 3, a T-shaped bracket, and an annular groove 16.

[0040] In actual use, the rotating block 3 is set in a crescent shape, and the center of the rotating block 3 is connected to the center point of the top of the T-shaped bracket. The annular groove 16 is fixedly connected to the outside of the T-shaped bracket, so that the three ends of the T-shaped bracket and the inner ring of the annular groove 16 form an internal structure.

[0041] An iron plate 18 is provided between the T-shaped bracket and the rotating block 3; the top of the iron plate 18 is connected to the center point of the top of the T-shaped bracket, one side of the bottom of the iron plate 18 is connected to the slider 17 in the annular groove 16, and the other side of the bottom of the iron plate 18 is fixedly connected to the rotating block 3.

[0042] Two springs are provided in the annular groove 16. The two springs are respectively arranged on both sides of the slider 17 in the annular groove 16 to form a symmetrical structure. Thus, when the rotating block 3 is not compressed, the iron sheet 18 and the rotating block 3 are located on the center line of the annular groove 16.

[0043] The locking block 4 is slidably connected to the rotating block 3, and the contact surfaces of the locking block 4 and the rotating block 3 are provided with protrusions and grooves that can be locked together.

[0044] As the locking block 4 enters the rotating part, it can compress the rotating block 3. As the locking block 4 compresses the rotating block 3, it not only drives the rotating block 3 to rotate, but also causes the groove on the locking block 4 to engage with the protrusion on the rotating block 3. Because the top of the rotating block 3 engages with the rotating part, the rotating block 3 stops rotating, thus locking the locking block 4 and the rotating block 3 together.

[0045] The snap-fit ​​part mainly consists of a long strip block 8, an upper horizontal bar 7, and a fixing frame.

[0046] The mounting bracket is fixedly connected to the inner wall of the outer casing 1. A latch is provided at one end of the long strip 8, which can engage with the top of the rotating block 3. The other end of the long strip 8 is fixedly connected to one end of the upper horizontal rod 7. The mounting bracket has a through hole, and the other end of the upper horizontal rod 7 is slidably connected to the through hole of the mounting bracket. A compression spring is fitted onto the upper horizontal rod 7, with one end abutting against the end of the long strip 8 and the other end in contact with the mounting bracket.

[0047] In actual use, when the rotating block 3 is engaged with the end of the long strip block 8 and is pressed, the compression spring on the upper horizontal bar 7 applies a reverse elastic force to the long strip block 8, thereby making the engagement between the rotating block 3 and the long strip block 8 more stable.

[0048] It also includes a Z-shaped connecting rod, a fan-shaped connecting iron plate 5, an L-shaped fixing bracket, and a lower horizontal bar 12.

[0049] The L-shaped brackets are all fixedly connected to the inner wall of the outer casing 1. The top of the Z-shaped connecting rod is fixedly connected to the button 2, the middle of the Z-shaped connecting rod is connected to the long strip 8, and the bottom of the Z-shaped connecting rod is engaged with the top of the fan-shaped connecting iron plate 5. The bottom of the Z-shaped connecting rod is provided with a slot, which engages with the top of the fan-shaped connecting iron plate 5.

[0050] The center of the fan-shaped connecting iron plate 5 is connected to one side of the L-shaped fixing frame. A torsion spring 10 is provided at the connection between the fan-shaped connecting iron plate 5 and the L-shaped fixing frame. The two sides of the torsion spring 10 are connected to the fan-shaped connecting iron plate 5 and the L-shaped fixing frame respectively, and the torsion spring 10 can drive the fan-shaped connecting iron plate 5 to rotate counterclockwise.

[0051] The lower horizontal bar 12 is located on the other side of the L-shaped fixing frame, with one end of the lower horizontal bar 12 vertically connected to one end of the connecting thin rod 11. The other end of the connecting thin rod 11 is inserted into the elongated hole 19 at the bottom of the fan-shaped connecting iron plate 5. The elongated hole 19 at the bottom of the fan-shaped connecting iron plate 5 is inclined upward along the surface of the fan-shaped connecting iron plate 5. The other end of the lower horizontal bar 12 is provided with an adjusting bolt 20, which is in contact with one side of the iron plate 18.

[0052] The sliding rod 13 is parallel to the lower horizontal rod 12, and the sliding rod 13 passes through the protrusion in the middle of the lower horizontal rod 12, forming a sliding connection with the protrusion in the middle of the lower horizontal rod 12. Since both ends of the sliding rod 13 are fixedly connected to the inner wall of the outer casing 1, the lower horizontal rod 12 is supported in the outer casing 1.

[0053] In actual use, the operator presses button 2, causing the Z-shaped connecting rod to drive the long strip 8 to press against the compression spring on the upper horizontal rod 7, thus releasing the engagement between the rotating block 3 and the end of the long strip 8. This also releases the engagement between the locking block 4 and the rotating block 3, allowing the refrigerator door to be opened. During the opening process, the slider 17 in the annular groove 16 is reset under the action of the spring in the annular groove 16, thereby causing the rotating block 3 to rotate counterclockwise.

[0054] As the rotating block 3 rotates counterclockwise, the slider 17 immediately returns to its original position. The slider 17 drives the iron plate 18 to impact the adjusting bolt 20, thereby pushing the lower horizontal bar 12. This causes the connecting rod 11 on the lower horizontal bar 12 to move in the elongated hole 19 at the bottom of the fan-shaped connecting iron plate 5. The fan-shaped connecting iron plate 5 rotates counterclockwise under the action of the torsion spring 10, so that the top of the fan-shaped connecting iron plate 5 is engaged in the slot at the bottom of the Z-shaped connecting rod.

[0055] Similarly, when the refrigerator door is closed, the operator presses button 2, causing the Z-shaped connecting rod to drive the long block 8 to press against the compression spring on the upper horizontal rod 7. The bottom of the Z-shaped connecting rod shifts, pushing the fan-shaped connecting iron piece 5 to rotate clockwise. This clockwise rotation of the fan-shaped connecting iron piece 5 moves the connecting rod 11 in the long hole 19 from one end to the other, thereby pushing the lower horizontal rod 12 back to its original position. This releases the engagement between the top of the fan-shaped connecting iron piece 5 and the slot at the bottom of the Z-shaped connecting rod, allowing the long block 8 to return to its original position. When the refrigerator door is closed, the locking block 4 presses against the rotating block 3 and causes it to rotate until the rotating block 3 engages with the returned long block 8.

[0056] The adjustment assembly consists of an adjusting threaded rod 15, an adjusting bracket, a U-shaped hole, and an adjusting block 14.

[0057] The adjusting bracket is U-shaped, and one side of the adjusting bracket is fixedly connected to the inner wall of the outer casing 1. The adjusting threaded rod 15 passes through the adjusting bracket and the adjusting block 14, and the adjusting block 14 and the adjusting threaded rod 15 form a threaded connection, while one side of the adjusting block 14 is fixedly connected to the T-shaped bracket.

[0058] The U-shaped hole is opened along the length of the lower horizontal bar 12 and is located at the connection between the adjusting bolt 20 and the lower horizontal bar 12.

[0059] In actual use, first loosen the adjusting bolt 20, then rotate the adjusting threaded rod 15 to move the adjusting block 14, thereby adjusting the position of the T-shaped bracket. During the movement of the T-shaped bracket, the adjusting bolt 20 is pressed and moves along the length of the U-shaped hole. After the T-shaped bracket is properly adjusted, tighten the adjusting bolt 20.

[0060] This design is not only simple in structure but also easy to adjust, making it easy to use and improving the overall convenience of the door lock.

[0061] In addition, a hanging ear is provided at the bottom of the locking block 4, and a large through hole is provided on the outer shell 1. When the locking block 4 and the rotating block 3 are engaged, the hanging ear hole is aligned with the large through hole of the outer shell 1. Then, a brass padlock is installed in the aligned hanging ear hole and the large through hole of the outer shell 1, so that a locking structure that cannot be opened or closed at will is formed between the refrigerator door and the side wall, thus making the entire lock body suitable for more usage scenarios.
