Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically a refrigerator door hinge. Background Technology

[0002] The refrigerator door hinge is a key component connecting the refrigerator door to the refrigerator body. It allows the refrigerator door to open and close smoothly. The refrigerator door can rotate through the pivot on the hinge. However, existing hinges still have certain defects in use.

[0003] In the existing technology, the materials of refrigerator door hinges are usually zinc alloy and iron parts. The rotating shaft on the hinge is made by die casting or welding of the optical shaft, which does not meet the radial mechanical requirements and has burrs at the root. In addition, the traditional rotating shaft is directly inserted into the support plate. The end of the rotating shaft is prone to falling off under force, which affects the opening and closing of the refrigerator door. Utility Model Content

[0004] The purpose of this utility model is to provide a refrigerator door hinge to solve the problem mentioned in the background art that the hinge rotation shaft in the current market is prone to falling off.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a refrigerator door hinge, comprising: a hinge body, a mounting hole, and a support plate. The mounting hole is provided through the interior of the hinge body. A support plate is welded to the front of the hinge body. A dual-axis guide rod is formed by die casting and extends through the surface of the support plate. A pressure plate is integrally formed by die casting on the outer side of the dual-axis guide rod. A semi-conical body is machined on the outer side of the dual-axis guide rod near the pressure plate using a lathe. A snap-fit ​​groove is provided between the two pressure plates. A rubber sleeve is fitted onto the outer side of the dual-axis guide rod.

[0006] Preferably, a pivot is welded to the front of the hinge body, and a baffle is rotatably connected to the outer side of the pivot.

[0007] Preferably, a connecting block is welded to the front of the hinge body, and the baffle is made of iron.

[0008] Preferably, the hinge body and the support plate are made of aluminum alloy, and two sets of rubber sleeves are symmetrically arranged about the center of the dual-axis optical rod.

[0009] Preferably, the baffle and the rotating shaft form a rotating structure.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This refrigerator door hinge can fix the dual-axis guide rod and the support plate together by die casting using a mold through a snap-fit ​​groove. At the same time, the surface of the semi-cone is processed and polished to be smooth to avoid burrs, making it less likely for the refrigerator door to turn unevenly. During the installation of the refrigerator door, the ends of the dual-axis guide rod will be subjected to pressure. At this time, the pressure plate can prevent the dual-axis guide rod from falling off, thus meeting the mechanical requirements. Since the hinge body and the support plate are made of aluminum alloy, the overall weight of the hinge can be reduced. After the hinge body is installed by screws through the mounting holes, the baffle is pushed. When the baffle moves, it can be rotated through the pivot. When one side of the baffle rotates to the outside of the screw inside the mounting hole, the baffle can fall on the surface of the connecting block. The baffle can prevent the screw inside the mounting hole from loosening or falling off, thereby improving the safety of the hinge during use. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 , Figure 2 and Figure 3It is understood that this utility model provides a technical solution: a refrigerator door hinge, including: a hinge body 1, a mounting hole 2 and a support plate 3. The mounting hole 2 is opened through the interior of the hinge body 1. The support plate 3 is welded to the front of the hinge body 1. The dual-axis guide rod 4 is formed by die casting and passes through the surface of the support plate 3. The outer side of the dual-axis guide rod 4 is integrally formed by die casting with a pressure plate 5. The outer side of the dual-axis guide rod 4 near the pressure plate 5 is machined with a half cone 6 by a lathe. A snap-fit ​​groove 7 is opened between the two pressure plates 5. A rubber sleeve 8 is sleeved on the outer side of the dual-axis guide rod 4. A rotating shaft 9 is welded to the front of the hinge body 1. A baffle 10 is rotatably connected to the outer side of the rotating shaft 9. A connecting block 11 is welded to the front of the hinge body 1. The baffle 10 is made of iron. The hinge body 1 and the support plate 3 are made of aluminum alloy. Two sets of rubber sleeves 8 are symmetrically arranged about the center of the dual-axis guide rod 4. The baffle 10 and the rotating shaft 9 form a rotating structure. The baffle 10 and the hinge body 1 are tightly fitted.

[0017] In practice, the dual-axis guide rod 4 and the support plate 3 can be fixed together by die casting using a mold through the locking groove 7. At the same time, the surface of the semi-cone 6 is machined and polished to be smooth to avoid burrs, so that the refrigerator door is less likely to have difficulty turning. During the installation of the refrigerator door, the end of the dual-axis guide rod 4 will be subjected to pressure. At this time, the pressure plate 5 can prevent the dual-axis guide rod 4 from falling off, thereby meeting the mechanical requirements. The rubber sleeve 8 is fitted on the outside of the dual-axis guide rod 4, so that the refrigerator door can reduce the collision between the refrigerator door and the support plate 3 during the installation process. Since the hinge body 1 and the support plate 3 are made of aluminum alloy, the overall weight of the hinge can be reduced, making the installation process more convenient. After the hinge body 1 is installed by screws through the mounting holes 2, the baffle 10 is pushed. When the baffle 10 moves, it can be rotated through the pivot 9.

[0018] See Figure 1 , Figure 2 and Figure 3 It can be seen that when the baffle 10 rotates to the outside of the screw inside the mounting hole 2, the baffle 10 can fall on the surface of the connecting block 11. The baffle 10 can prevent the screw inside the mounting hole 2 from loosening and falling off, thereby improving the safety of the hinge during use.

[0019] In summary, when using this refrigerator door hinge, the dual-axis guide rod 4 and the support plate 3 can be fixed together by die casting using a mold through the locking groove 7. At the same time, the surface of the semi-cone 6 is machined and polished to be smooth to avoid burrs, making it less likely for the refrigerator door to turn unevenly. During the installation of the refrigerator door, the end of the dual-axis guide rod 4 will be subjected to pressure. At this time, the pressure plate 5 can prevent the dual-axis guide rod 4 from falling off, thus meeting the mechanical requirements. When one side of the baffle 10 rotates to move to the outside of the screw inside the mounting hole 2, the baffle 10 can fall on the surface of the connecting block 11. The baffle 10 can prevent the screw inside the mounting hole 2 from loosening and falling off, thereby improving the safety of the hinge during use.
