[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] The refrigerator of the present invention includes a refrigerator body 10 and a refrigerator door body 20. A lock fixing part 4 is fixed on the refrigerator body 10, and a switch door lock structure 30 is fixed on the refrigerator door body 20. The switch lock structure 30 includes a lock box component 1, a lock pressing piece 2, a lock rod 3, and a lock rod fixing part 5. The lock fixing part 4 includes a screw hole 4-2 and a lock fixing part hole 4-1. The lock fixing part 4 is fixed on the refrigerator body by driving a screw into the screw hole 4-2. The lock box component 1 includes a recessed part 1-5. An installation hole 1-2 is formed on the lower surface of the recessed part 1-5. A fixing structure 1-3 is formed on the upper surface of the lock box component 1, and a fixing part 1-4 is formed on the lower surface of the lock box component 1. The lock box component 1 is installed on the refrigerator door body through the fixing structure 1-3 and the fixing part 1-4.

[0019] The lock pressing piece 2 is installed in the recessed part 1-5. It includes a connecting part 2-1 and a threaded hole 2-2 formed integrally with the connecting part 2-1. The threaded hole 2-2 is vertically aligned with the installation hole 1-2. The lock rod fixing part 5 is installed on the upper surface of the lock box component 1 and is located on one side of the fixing structure 1-3. An installation receiving hole 5-1 is formed on the lock rod fixing part 5. The lock rod 3 includes a threaded structure 3-1, a connecting rod 3-3 located above the threaded structure 3-1, and a lock rod head structure 3-2 located below the threaded structure 3-1. The lower end of the lock rod head structure 3-2 is provided with a rounded corner.

[0020] The working principle of the switch door lock structure of the refrigerator of the present invention is as follows: The switch door lock structure is installed on the refrigerator door body through the fixing structure 1-3 and the fixing part 1-4. When the refrigerator starts to open the door, since a force is applied by pressing the hand on the structural surface of the connecting part 2-1 of the lock pressing piece 2, the pressure received by the connecting part 2-1 makes the threaded hole 2-2 cooperate with the threaded structure 3-1 on the lock rod 3 to perform a rotational movement. Due to the thread, the lock rod 3 then moves upward, compressing the spring 40 installed on the lock rod 3. Since the lock rod 3 moves upward, the lock rod head structure 3-2 on the lock rod 3 disengages from the lock fixing part hole 4-1 on the lock fixing part 4, enabling the door to be opened. After the door is opened, the hand releases the structural surface of the connecting part 2-1 of the lock pressing piece 2-1. Due to the action of the spring, the spring acts on the lock rod 3, causing it to move downward. At the same time, the threaded structure 3-1 on the lock rod 3 interacts with the threaded hole 2-2 on the lock pressing piece, causing it to return to its initial position. When closing the refrigerator door body, due to the rounded corner of the lock rod head structure 3-2 on the lock rod 3, it will lift upward when contacting the lock fixing part 4, compressing the spring, and the lock pressing piece 2 will also move due to the threaded structure 3-1 on the lock rod 3. When the lock rod head structure 3-2 on the lock rod 3 moves to cooperate with the lock fixing part hole 4-1 on the lock fixing part 4, the spring releases its elastic force, causing the lock to return to its initial state.

[0021] In the present invention, the lock rod fixing part 5 cooperates with the lock box component 1. The installation receiving hole 5-1 on the lock rod fixing part 5 cooperates with the connecting rod 3-3 on the lock rod 3, and the installation hole 1-2 of the lock box component 1 cooperates with the lock rod head structure 3-2, enabling the lock rod to always rotate and move up and down at the same central position.

[0022] The present invention mainly uses the lock pressing piece 2. By pressing the lock pressing piece 2 when opening the door, the threaded hole 2-2 in the lock pressing piece 2 interacts with the threaded structure 3-1 on the lock rod 3, causing the lock rod 3 to lift upward, and the lock rod head structure 3-2 to disengage from the lock fixing part hole 4-1, so as to achieve the purpose of opening and closing the door by pressing the lock pressing piece 2. After the lock rod 3 disengages from the lock fixing part hole 4-1, the lock pressing piece 2 is released, and the spring on the lock rod 3 presses the lock rod 3 downward. The threaded hole 2-2 in the lock pressing piece 2 interacts with the thread 3-1 on the lock rod 3, causing the lock pressing piece 2 to return to its original position.

[0023] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, several improvements can be made without departing from the principle of the present invention, and these improvements should also be regarded as the protection scope of the present invention.
