Abstract
Description
Technical Field
[0001] This utility model specifically relates to a cabinet door structure for a refrigerator. Background Technology
[0002] As a common refrigeration device, the sealing and opening / closing stability of refrigerator doors directly affect the energy efficiency and user experience. Traditional refrigerator doors often use magnetic sealing strips for closure. When the refrigerator is first delivered to the user's home, it is packed in a box, which may cause the door to open accidentally during transportation or handling. However, when the user needs to move the refrigerator, the box is often not available, and the refrigerator needs to be moved directly. During the handling of the refrigerator, the magnetically closed door is easily opened by force, which affects the handling of the refrigerator. The accidental opening and collision of the door can also cause damage to the door, failing to meet the user's needs. Utility Model Content
[0003] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide a cabinet door structure for a refrigerator.
[0004] A refrigerator door structure includes a cabinet body and a door that can be opened and rotatably disposed on the front side of the cabinet body. The door body has a first groove recessed at its rotatable opening end. A first limiting member is rotatably disposed in the first groove, and the rotation direction of the first limiting member is opposite to the rotation direction of the door body. The first limiting member can be rotatably accommodated in the first groove or rotatably protrude outward from the outside of the first groove. A second limiting member is rotatably disposed on one side of the cabinet body. One end of the second limiting member has a hook portion, which can be hooked onto the first limiting member to restrict the opening of the door body.
[0005] In one embodiment, the hook faces the rear side of the cabinet, such that the hook rotates with the second limiting member and hooks onto the upper side of the first limiting member.
[0006] In one embodiment, a second groove is recessed on one side of the cabinet to engage with the second limiting member. A rotating shaft is provided in the second groove. The second limiting member is rotatably sleeved on the rotating shaft and can be displaced along the axial direction of the rotating shaft, so that the second limiting member is fitted and housed in the second groove.
[0007] In one embodiment, the second groove includes a circular groove and an L-shaped groove communicating with the lower side of the circular groove. The depth of the circular groove is greater than the depth of the L-shaped groove. The rotating shaft is disposed at the center of the circular groove and its axial length is equal to the depth of the circular groove. The second limiting member includes a collar and a connecting arm connected to the lower side of the collar. The hook is formed at the lower end of the connecting arm. The thickness of the collar is greater than the thickness of the connecting arm.
[0008] In one embodiment, the rotating shaft has a first threaded section and a smooth section along its axial direction. The first threaded section is located near the opening end of the circular groove, and the diameter of the first threaded section is larger than the diameter of the smooth section. The collar has a second threaded section that can be threadedly engaged with the first threaded section. When the first threaded section and the second threaded section are threadedly engaged, the connecting arm disengages from the L-shaped groove.
[0009] In one embodiment, the door body is provided with a third groove on the opposite side of its rotating opening end, and a third limiting member is rotatably disposed in the third groove. The structure of the third limiting member is the same as that of the first limiting member.
[0010] In one embodiment, the cabinet has recessed grips on both sides.
[0011] In summary, the advantages of this utility model over the prior art are:
[0012] This utility model uses the hook of the first limiting member of the door and the hook of the second limiting member of the cabinet to form a multi-point force locking, which effectively resists door vibration or external impact, avoids accidental opening, and facilitates user handling.
[0013] Furthermore, the second limiting component can be rotated and stored in the second groove, unfolded when in use, and fully embedded in the cabinet when not in use, avoiding protrusion and space occupation. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0019] like Figures 1 to 4The present invention preferably provides a refrigerator door structure, including a cabinet body 1 and a door 2 that is rotatably and openably disposed on the front side of the cabinet body 1. The door 2 has a first recess 3 recessed at its rotatable opening end. A first limiting member 4 is rotatably disposed within the first recess 3, and the rotation direction of the first limiting member 4 is opposite to the rotation direction of the door 2. The first limiting member 4 can be rotatably accommodated within the first recess 3 or rotatably protrude outward from the outside of the first recess 3. A second limiting member 5 is rotatably disposed on one side of the cabinet body 1. One end of the second limiting member 5 has a hook 6, which can be hooked onto the first limiting member 4 to restrict the opening of the door 2. Specifically, the hook-and-hook interaction between the first limiting member of the door and the hook of the second limiting member of the cabinet body forms a multi-point locking mechanism, effectively resisting door vibration or external impact, preventing accidental opening, facilitating user handling, and when not in use, the first limiting member can be accommodated within the first recess without protruding outward and affecting the placement and use of the refrigerator.
[0020] Furthermore, the hook 6 faces the rear side of the cabinet 1, so that the hook 6 rotates with the second limiting member 5 and hooks onto the upper side of the first limiting member 4. Furthermore, by having the hook face the rear side of the cabinet, when the hook rotates with the second limiting member and hooks onto the first limiting member, the weight of the second limiting member maintains the connection between the hook and the first limiting member, preventing it from detaching due to gravity.
[0021] Furthermore, one side of the cabinet 1 has a recessed second groove 7 that can engage with the second limiting member 5. A rotating shaft 8 is provided within the second groove 7. The second limiting member 5 is rotatably sleeved on the rotating shaft 8 and can move axially along the rotating shaft 8, so that the second limiting member 5 is fitted and housed within the second groove 7. Furthermore, the second limiting member can move axially along the rotating shaft, allowing it to disengage from or be housed within the second groove. After disengaging from the second groove, the second limiting member can rotate around the rotating shaft and hook onto the first limiting member, enabling it to unfold when in use and be fully embedded in the cabinet when not in use, avoiding outward protrusion and space occupation.
[0022] Furthermore, the second groove 7 includes a circular groove 71 and an L-shaped groove 72 communicating with the lower side of the circular groove 71. The depth of the circular groove 71 is greater than the depth of the L-shaped groove 72. The rotating shaft 8 is disposed at the center of the circular groove 71 and its axial length is equal to the depth of the circular groove 71. The second limiting member 5 includes a collar 51 and a connecting arm 52 connected to the lower side of the collar 51. The hook 6 is formed at the lower end of the connecting arm 52. The thickness of the collar 51 is greater than the thickness of the connecting arm 52.
[0023] Furthermore, the rotating shaft 8 has a first threaded section 81 and a smooth section 82 along its axial direction. The first threaded section 81 is located near the opening end of the circular groove 71, and the diameter of the first threaded section 81 is larger than the diameter of the smooth section 82. The collar 51 has a second threaded section 83 that can be threadedly engaged with the first threaded section 81. When the first threaded section 81 and the second threaded section 83 are threadedly engaged, the connecting arm 52 disengages from the L-shaped groove 72.
[0024] Specifically, when the second limiting member is housed in the second groove, the second threaded section of the collar portion of the second limiting member is located on the smooth section of the rotating shaft. Because the diameter of the second threaded section is larger than the diameter of the smooth section, the second limiting member can be displaced along the axial direction of the smooth section. When the second limiting member is displaced along the axial direction of the rotating shaft towards the first threaded section of the rotating shaft, the connecting arm in the second limiting member disengages from the L-shaped groove. At this time, the second threaded section of the collar in the second limiting member can be threadedly engaged with the first threaded section of the rotating shaft. Then, the user can rotate the second limiting member to make the first threaded section and the second threaded section fully threadedly engaged, and then rotate and flip out the first limiting member, causing the second limiting member to hook onto the first limiting member. The self-locking of the second limiting member is achieved through the threaded engagement.
[0025] Furthermore, the second threaded section of the second limiting member rotates clockwise toward the cabinet door relative to the first threaded section of the rotating shaft. That is, when the second limiting member is engaged with the first limiting member, the first limiting member can prevent the second limiting member from loosening around the rotating shaft thread.
[0026] Furthermore, the door 2 has a third groove 11 on the opposite side of its rotating opening end, and a third limiting member 12 is rotatably disposed in the third groove 11. The structure of the third limiting member 12 is the same as that of the first limiting member 4. By having the first limiting member and the third limiting member on both sides, a force fulcrum can be provided during handling, which facilitates the manual support and handling of large refrigerated boxes when going up and down stairs.
[0027] Furthermore, the cabinet body 1 has recessed grips 13 on both sides. The grips on both sides of the cabinet body provide fulcrums for applying force, making it easy to move or adjust the position of the cabinet.
[0028] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
