Technical fields:
[0001] This utility model relates to a refrigerator lower hinge structure and the refrigerator thereof, which belongs to the field of household appliance technology. Background technology:
[0002] With the development of the times, refrigerators, as a commonly used household appliance in daily life, are receiving increasing attention from users regarding their user experience. Issues such as abnormal noise when opening the refrigerator door and the smoothness of the door opening are easily noticeable to users. Currently, refrigerator manufacturers are all trying to solve these problems. Utility model content:
[0003] This utility model provides a refrigerator lower hinge structure and refrigerator to solve the problems existing in the prior art. It can increase the smoothness of opening the refrigerator door and reduce the abnormal noise generated when the refrigerator door is opened, thereby improving the user experience.
[0004] This utility model adopts the following technical solution: a refrigerator lower hinge structure, including a door closer, a lower hinge shaft, a lower hinge body, an adjusting foot assembly, and a roller assembly. The lower hinge body has a lower hinge shaft mounting hole for the lower hinge shaft to pass through and be installed therein. The door closer has a door closer hole for the lower hinge shaft to pass through. The lower hinge shaft is positioned above the lower hinge body and passes through the door closer hole. The adjusting foot assembly includes an adjusting foot shaft and an adjusting foot screwed onto the outside of the adjusting foot shaft. An adjustment foot mounting hole is formed on the lower hinge body at one side of the lower hinge shaft mounting hole, for the adjustment foot shaft to pass through and be fixed therein. After the adjustment foot shaft is passed through and fixed in the adjustment foot mounting hole, the adjustment foot is located below the lower hinge body. The height of the adjustment foot can be adjusted by tightening or loosening the adjustment foot. A pin mounting hole is formed on the end side wall of the lower hinge body away from the lower hinge shaft mounting hole. The roller assembly includes a pin that passes through and is fixed in the pin mounting hole and a roller that is rolled on the pin.
[0005] Furthermore, after the upper end of the lower hinge shaft passes through the lower hinge shaft mounting hole, the lower end of the lower hinge shaft is welded together with the lower surface of the lower hinge body.
[0006] Furthermore, a hinge body stop is formed by a protrusion at the corner of the lower hinge body adjacent to the mounting hole of the lower hinge shaft.
[0007] Furthermore, the door closer has a plurality of spaced mounting posts protruding on one side of the door closer hole, and the lower hinge body has a plurality of mounting holes corresponding to the mounting posts on one side of the lower hinge shaft mounting hole.
[0008] Furthermore, the mounting post of the door closer is interference-fitted with the mounting hole and secured together.
[0009] The present invention also adopts the following technical solution: a refrigerator, including a refrigerator door and a refrigerator body, wherein the refrigerator body is equipped with the aforementioned refrigerator lower hinge structure, and the lower end of the refrigerator door is provided with a door end cover, wherein a door suction device and a door stop are installed on the door end cover, and the door suction device and the door stop can slide relative to each other during the opening and closing of the refrigerator door.
[0010] Furthermore, a pivot hole is formed on the end cap of the door body at a position on one side of the door body stop, in which the upper end of the lower hinge shaft can rotate.
[0011] This utility model has the following beneficial effects:
[0012] (1) The parts of this utility model have a simple installation structure and no screw fixing process, which reduces labor costs and is suitable for large-scale production by manufacturers.
[0013] (2) The present invention eliminates the stop part on the lower hinge body and replaces it with a hinge body stop formed by a protrusion at one corner of the lower hinge body. The hinge body stop acts as a stop part, reducing one sub-part and its installation process, thus reducing costs and increasing efficiency.
[0014] (3) This utility model uses a door closer and a door suction device, both of which are made of self-lubricating material. When they slide against each other, there is no abnormal noise and the smoothness is improved, resulting in a long service life. Attached image description:

[0019] The present invention will be further described below with reference to the accompanying drawings.
[0020] This utility model relates to a refrigerator lower hinge structure, which is installed on the refrigerator body. It includes a door closer 1, a lower hinge shaft 2, a lower hinge body 3, an adjusting foot assembly 4, and a roller assembly 5. The lower hinge body 3 has a lower hinge shaft mounting hole 30 for the lower hinge shaft 2 to pass through and be installed therein. After the upper end of the lower hinge shaft 2 passes through the lower hinge shaft mounting hole 30, the lower end of the lower hinge shaft 2 is welded to the lower surface of the lower hinge body 3. A hinge body stop 34 protrudes from a corner of the lower hinge body 3 adjacent to the lower hinge shaft mounting hole 30. The door closer 1 has a door closer hole 10 for the lower hinge shaft 2 to pass through, and several spaced-apart mounting posts 11 protrude from one side of the door closer hole 10 on the door closer 1. Several mounting holes 31 corresponding to the mounting posts 11 are formed on one side of the lower hinge shaft mounting hole 30 on the lower hinge body 3. The mounting post 11 of the door closer 1 is interference-fitted with the mounting hole 31 and secured together. At this time, the lower hinge shaft 2 is inserted into the door closer hole 10 at a position above the lower hinge body 3.
[0021] The adjusting foot assembly 4 includes an adjusting foot shaft 40 and an adjusting foot 41 screwed onto the outside of the adjusting foot shaft 40. An adjusting foot shaft mounting hole 32 is formed on the lower hinge body 3 on one side of the lower hinge shaft mounting hole 30, allowing the adjusting foot shaft 40 to pass through and be fixed therein. After the adjusting foot shaft 40 is inserted and fixed in the adjusting foot shaft mounting hole 32, the adjusting foot 41 is located below the lower hinge body 3, and its height can be adjusted by tightening or loosening the adjusting foot 41.
[0022] A pin mounting hole 33 is formed on the end side wall of the lower hinge body 3 away from the lower hinge shaft mounting hole 30. The roller assembly 5 includes a pin 50 that passes through and is fixed in the pin mounting hole 33 and a roller 51 that is rolled on the pin 50.
[0023] The lower end of the refrigerator door is provided with a door end cover 6, on which a door suction aid 7 and a door stop 8 are installed. A rotating hole 60 is formed on the door end cover 6 on one side of the door stop 8, in which the upper end of the lower hinge shaft 2 can rotate.
[0024] The working principle of this refrigerator lower hinge structure is as follows: When the user closes the refrigerator door, the door suction device 7 and the door closer 1 slide against each other until they interfere and lock. At the same time, the door stop 8 restricts the degree of freedom of the door closer 1, and the refrigerator door is completely closed. When the user opens the refrigerator door, as the user pulls and rotates the door, the door closer 1 and the door suction device 7 slide against each other. When the door closer 1 disengages from the door suction device 7 until the hinge body stop 34 touches the door stop 8 on the door end cover 6, it means that the refrigerator door is opened to the maximum angle.
[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
