[0025] The utility model will be further described below in conjunction with the accompanying drawings.

[0026] Example

[0027] See also Figure 1-9 A refrigerator door lock structure includes a cabinet 1 and a door body. The door body is movably mounted on one side of the front of the cabinet 1, and the other side of the cabinet 1 is connected to the door body through a lock body and a door lock assembly 18.

[0028] The door lock assembly 18 includes a base 4 and a base plate 5. The base 4 is a long strip plate structure with two base through-holes 15 thereon. The base 4 is fixedly mounted on the front of the cabinet 1 through the base through-holes 15. The base plate 5 is arranged horizontally, one end of which is connected to the front of the base 4 and the other end of which has a first lock hole 8. The lock body is mounted on the door body and has a vertically extending lock head, which can be inserted into or out of the first lock hole 8.

[0029] The door lock assembly 18 also includes a rotating plate, which is arranged transversely and has a rotating plate portion 6 of a plate-like structure. Figure 8 As shown, the rotating plate portion 6 has a second locking hole 10 and a third locking hole 11 , and one end of the rotating plate portion 6 is located near the second locking hole 10 and also has a second axial hole 12 .

[0030] The base plate 5 of the door lock assembly 18 has a first shaft hole 90 near the first lock hole 8, and the rotating plate is rotatably connected to the base plate 5 through the second shaft hole 12, the first shaft hole 90 and the pin 9. The rotating plate can be rotated so that the second lock hole 10 and the first lock hole 8 overlap each other. Figure 5 and Figure 6 The rotating plate can also be rotated to make the second locking hole 10 away from the first locking hole 8, such as Figure 2 and Figure 3 .

[0031] In the above structure, when the lock head is inserted into the first lock hole 8, the door body is in a closed state. At this time, the rotating plate can be rotated to the second lock hole 10 away from the first lock hole 8, or the rotating plate can be rotated to the second lock hole 10 and the first lock hole 8 overlap up and down. The lock head is inserted into the first lock hole 8 and the second lock hole 10 in the overlapping state to realize the closed state of the door body.

[0032] When the user needs to keep the door open for a long time to defrost, clean and dry the refrigerator, the user first retracts the lock head into the lock body, then opens the door, and rotates the rotating plate until the third lock hole 11 end of the rotating plate is away from the base 4, that is, the third lock hole 11 end of the rotating plate is in a state of extending out of the base 4. Figure 5 and Figure 6 Then, the lock head is inserted into the third lock hole 11 of the rotating plate, and the position of the door body is restricted by the lock head through the third lock hole 11, so that the door body can be opened and maintained at a small angle.

[0033] Furthermore, the base plate 5 has a space 7 at one end close to the base 4, and the base plate 5 has a first clamping position 16 and a second clamping position 17, the first clamping position 16 is located in the space 7, and the second clamping position 17 is away from the base 4; the rotating plate has a clamping head 19, and when the second locking hole 10 coincides with the first locking hole 8, the clamping head 19 is clamped in the second clamping position 17; the second locking hole 10 can be away from the first locking hole 8 until the clamping head 19 is clamped in the first clamping position 16.

[0034] In the above structure, the clamping head 19 cooperates with the first clamping position 16 and the second clamping position 17 respectively, so as to realize the positioning and cooperation between the rotating plate and the base plate 5 when the door is closed and opened at a small angle, thereby ensuring that the rotating plate can be quickly and stably rotated to a suitable position.

[0035] Furthermore, the rotating plate of the door lock assembly 18 is in a U-shaped structure, and has two symmetrically arranged upper and lower rotating plate parts 6, and the two rotating plate parts 6 are symmetrically located above and below the base plate 5. The U-shaped rotating plate can improve the strength of the rotating plate and ensure the working durability of the rotating plate.

[0036] Furthermore, the two rotating plate parts 6 are connected at one end of the third locking hole 11 and serve as the connecting end of the rotating plate. There is a gap between the two rotating plate parts 6 at one end of the second locking hole 10 and they are then sleeved on the base plate 5, and the clamping head 19 is located in the gap. The above structure improves the assembly efficiency and rotation flexibility between the rotating plate and the base plate 5.

[0037] Further, the second locking hole 10 can be away from the first locking hole 8 to the connection end of the rotating plate and be stuck in the space 7. The space 7 cooperates with the connection end of the rotating plate to ensure the rotatable range of the rotating plate.

[0038] Further, this embodiment can also be used for refrigerators with upper and lower doors, specifically: the door body includes two, which are installed at intervals up and down as the upper door body 2 and the lower door body 3 respectively, the lock body includes two, which are installed on the upper door body 2 and the lower door body 3 respectively, the lock heads of the two lock bodies correspond to the upper lock head 13 and the lower lock head 14, the door lock assembly 18 is located between the upper door body 2 and the lower door body 3, and the upper lock head 13 and the lower lock head 14 are staggered up and down. The staggered upper lock head 13 and the lower lock head 14 can effectively avoid collision between the upper and lower lock heads.

[0039] When the upper door body 2 and the lower door body 3 are both in the closed state, the upper lock head 13 and the lower lock head 14 are both in the first lock hole 8 .

[0040] When the user needs to keep the door open for a long time to defrost, clean and dry the refrigerator, the two lock heads are retracted into the lock body, the two doors are opened, and the rotating plate is rotated until the third lock hole 11 end of the rotating plate is away from the base 4, that is, the third lock hole 11 end of the rotating plate is in a state of extending out of the base 4. Figure 5 and Figure 6 Then, the lock head is inserted into the third lock hole 11 of the rotating plate, and the position of the door body is restricted by the lock head through the third lock hole 11, so that the door body can be opened and maintained at a small angle.

[0041] Of course, users can also choose to close one door and open the other door at a small angle according to actual needs, such as Figure 6 and Figure 7 The upper door body 2 is shown to be opened at a small angle, and the lower door body 3 is closed. Specifically, the two lock heads are first retracted into the lock body, and the two doors are opened, and the rotating plate is rotated until the third lock hole 11 end of the rotating plate is away from the base 4, that is, the third lock hole 11 end of the rotating plate is in a state of extending out of the base 4, as shown in FIG. Figure 5 and Figure 6At this time, the second lock hole 10 and the first lock hole 8 are overlapped up and down, and the lower lock head 14 of the lower door body 3 is inserted back into the overlapped first lock hole 8 and the second lock hole 10 to realize the closed state of the lower door body 3. In addition, the upper lock head 13 of the upper door body 2 is inserted into the third lock hole 11 of the rotating plate, and the position of the upper door body 2 is restricted by the upper lock head 13 through the third lock hole 11, so that the upper door body 2 can be opened and maintained at a small angle.

[0042] In the above structure, the first lock hole 8, the second lock hole 10 and the third lock hole 11 are long strip holes, which ensure that the lock head can be easily inserted into each lock buckle when the door body rotates, and when there are two upper and lower lock heads, the two lock heads can be staggered to avoid collision.

[0043] Furthermore, the end of the lock head of the lock body is narrowed and thinned. This structure can avoid the ends of the two lock heads from being too large and colliding with each other while ensuring that the lock head has a certain strength.

[0044] When the utility model is in use, when the upper door body 2 and the lower door body 3 are completely closed, the upper lock head 13 and the lower lock head 14 are inserted into the first lock hole 8. When the upper door body 2 and the lower door body 3 are opened and the upper lock head 13 and the lower lock head 14 are retracted, the rotating plate can be rotated to the second locking position 17, and then the upper lock head 13 and the lower lock head 14 are extended and inserted into the second lock hole 10, so that the door is kept open at a small angle, which is used for defrosting and dissipating the refrigerator when it is not powered on. The length of the first lock hole 8, the second lock hole 10, and the third lock hole 11 are relatively long, so that the upper and lower lock heads can be staggered and installed left and right to avoid collision when closing the door.

[0045] When rotating the rotating plate, both the upper and lower doors need to be opened before rotating the rotating plate. In addition, the lock of one door can be inserted into the third lock hole 11 to close it, and the lock of the other door can be left in the second lock hole 10, so that one door is closed and the other door is opened at a small angle.
