Description

Technical field:

[0001] The utility model relates to a freely embedded refrigerator hinge, which belongs to the technical field of household appliances. Background technology:

[0002] The hinge structure of conventional refrigerator doors is mostly single-axis, and the door body rotates around the hinge axis through the cooperation of the hinge axis and the door body's shaft sleeve. When the door body of this type of hinge structure is opened, the corner of the door body will extend beyond the side of the box body; for built-in refrigerators, the refrigerator is generally placed in the cabinet. If a single-axis hinge structure is used, when the door is opened to 90°, the corner of the door body will extend beyond the side of the box body, and the door body will collide with the cabinet, causing damage to the door body.

[0003] Therefore, it is necessary to improve the existing technology to solve the shortcomings of the existing technology. Utility model content:

[0004] The present invention provides a free built-in refrigerator hinge in order to solve the problems existing in the above-mentioned prior art. It can solve the problem in the prior art that when the built-in refrigerator adopts a single-axis hinge structure and the door is opened from 0° to 90°, the corner of the door body will collide with the cabinet and cause damage to the door body.

[0005] The technical solutions adopted by the present invention include: a free-embedded refrigerator hinge, including a hinge assembly and a suction aid, the hinge assembly is installed on the refrigerator body, the suction aid is installed on the refrigerator door, the hinge assembly is fixed with a flat elliptical tube and a hinge shaft that are spaced apart from each other, the suction aid shaft that can run in the flat elliptical tube is fixed at a position opposite to the flat elliptical tube on the suction aid, and a curved slide groove for the hinge shaft to run in is formed at a position opposite to the hinge shaft on the suction aid.

[0006] Furthermore, the suction aid includes a suction aid body and a limit block fixed to one side of the suction aid body, and the curved sliding groove is formed on the suction aid body.

[0007] Furthermore, a mounting groove is formed in a recessed manner at a position on one side of the curved sliding groove on the main body of the suction aid, and the shaft of the suction aid is fixed in the mounting groove.

[0008] Furthermore, the hinge assembly includes a hinge body, which includes a connected hinge main body and a hinge extension. One end of the hinge main body is folded and extended to form a hinge connection part. A plurality of spaced first connection holes are respectively formed on the hinge extension part and the hinge connection part. Screws are screwed into the first connection holes to install the hinge assembly on the refrigerator body.

[0009] Furthermore, an elliptical hole and a first through hole spaced apart from each other are formed on a side of the hinge main body opposite to the hinge connecting portion, and the flat elliptical tube and the hinge shaft are fixed at the positions of the elliptical hole and the first through hole respectively.

[0010] Furthermore, second connecting holes are formed on the main body of the suction aid at positions on both sides of the curved slide groove.

[0011] Furthermore, a first notch portion is formed on the limit block, an extension portion is formed inwardly extending from a position below the first notch portion on the limit block, and a third connecting hole is formed on the extension portion. The suction aid body and the limit block are installed on the refrigerator door body by screwing screws into the second connecting hole and the third connecting hole opposite to the third connecting hole.

[0012] Furthermore, a second notch portion cooperating with the first notch portion is formed on one side surface of the suction aid, and the limiting block is installed at a suitable position on the suction aid body through the cooperation between the first notch portion and the second notch portion.

[0013] The utility model has the following beneficial effects: the free embedded refrigerator hinge of the utility model ensures that the corners of the door body do not exceed the side of the box body when the refrigerator door is opened by allowing the hinge axis and the suction aid axis to run in corresponding tracks respectively, thereby realizing the true embedding of the refrigerator into the cabinet.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] The present invention comprises a hinge assembly 1 and a suction aid 2. The hinge assembly 1 comprises a hinge body 10, which comprises a hinge main body 100 and a hinge extension 101. One end of the hinge main body 100 is folded and extended to form a hinge connection portion 102. The hinge extension 101 and the hinge connection portion 102 each have a plurality of spaced-apart first connection holes 103 formed therein. The hinge assembly 1 is mounted on the refrigerator cabinet by screwing screws into the first connection holes 103. On the side of the hinge main body 100 opposite the hinge connection portion 102, spaced-apart elliptical holes 104 and first through-holes 105 are formed therein. A flat elliptical tube 11 and a hinge shaft 12 are fixedly connected to the hinge main body 100 at the locations of the elliptical holes 104 and the first through-holes 105, respectively. Alternatively, the flat elliptical tube 11 and the hinge shaft 12 may be integrally formed on the hinge body 10.

[0021] The suction aid 2 includes a suction aid body 20 and a stopper 21. The suction aid body 20 is recessed with a spaced-apart mounting groove 200 and a curved slide 201. The mounting groove 200 is fixedly connected to a suction aid shaft 22. As an alternative embodiment, the suction aid shaft 22 can also be integrally formed with the suction aid body 20. Second connecting holes 202 are formed on the suction aid body 20 on either side of the curved slide 201. A first notch 210 is formed on the stopper 21. An extension 211 extends inwardly from the position below the first notch 210 on the stopper 21. A third connecting hole 2110 is formed on the extension 211. A second notch 23 is formed on one side of the suction aid 2, which mates with the first notch 210. The first notch 210 and the second notch 23 mate to secure the stopper 21 to the appropriate position on the suction aid body 20. The suction aid body 20 and the stopper 21 are then secured to the refrigerator door by screwing screws into the second connecting hole 202, which is opposite the third connecting hole 2110, and the third connecting hole 2110. The stopper 21 on the suction aid 2 limits the refrigerator door from opening more than 90 degrees. Screws are also screwed into the third connecting hole 2110 on the extension 211 to secure the suction aid 2 to the refrigerator door.

[0022] The working principle of the free-embedded refrigerator hinge of the present invention is as follows: When the refrigerator door is opened or closed, the coordination between the hinge assembly 1 and the suction aid 2 is as follows: the suction aid shaft 22 corresponds to the position of the flat elliptical tube 11, and the hinge axis 12 corresponds to the position of the curved chute 201. When the suction aid shaft 22 runs within the flat elliptical tube 11 on the hinge assembly 1, the flat elliptical tube 11 acts as a track limiter for the suction aid shaft 22. When the hinge axis 12 runs within the curved chute 201, the curved chute 201 acts as a track limiter for the hinge axis 12. When the refrigerator door opens from an angle of 0° to 90°, the hinge axis 12 and the suction aid shaft 22 run within the curved chute 201 and the flat elliptical tube 11, respectively. The free-embedded refrigerator hinge of the present invention ensures that the corners of the refrigerator door do not extend beyond the side of the cabinet when the door is opened by allowing the hinge axis 12 and the suction aid shaft 22 to run within their respective tracks, thereby achieving a true integration of the refrigerator into the cabinet.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be regarded as the scope of protection of the present invention.
