[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This utility model provides an improved refrigerator hinge that is easy to install. The technical solution of this utility model is as follows:

[0024] like Figures 1 to 4 As shown, an easy-to-install refrigerator hinge includes a first hinge plate 1 and a second hinge plate 2. The first hinge plate 1 is a hollow "L"-shaped structure, and the second hinge plate 2 is a rectangular structure. The first hinge plate 1 and the second hinge plate 2 are arranged vertically. During installation, the first hinge plate 1 is installed on the top of the refrigerator, and the second hinge plate 2 is installed on the side wall of the refrigerator. A support plate 3 is fixedly installed on the second hinge plate 2. The support plate 3 is a rectangular structure. A first hinge shaft 4 is installed on the support plate 3. The first hinge shaft 4 is a cylindrical structure. A placement groove 5 is opened inside the first hinge plate 1 corresponding to the position of the first hinge shaft 4. The placement groove 5 penetrates the bottom wall of the first hinge plate 1. A second hinge shaft 6 is movably installed inside the placement groove 5. The second hinge shaft 6 is a cylindrical structure. The refrigerator door is located between the first hinge shaft 4 and the second hinge shaft 6. A second sliding cover 10 is movably installed on the first hinge plate 1. The second sliding cover 10 is a hollow structure. A positioning mechanism is provided on the first hinge plate 1 corresponding to the position of the second sliding cover 10.

[0025] The positioning mechanism includes a pressure block 11, an adjusting groove 12, an adjusting shaft 13, a transmission block 14, and a knob 15. The pressure block 11 is a rectangular block, fixedly installed at the bottom of the second sliding cover 10. The adjusting groove 12 is a rectangular groove, located on the top side of the first hinge plate 1. The adjusting shaft 13 is a threaded cylindrical structure, movably installed inside the adjusting groove 12. The transmission block 14 is a rectangular block, fixedly installed at the bottom of the second sliding cover 10, located inside the adjusting groove 12, and the adjusting shaft 13 passes through the side wall of the transmission block 14 and is threadedly connected to it. The knob 15 is located on the outer side wall of the first hinge plate 1, and is fixedly connected to the adjusting shaft 13. This mechanism allows the refrigerator door to be installed between the first hinge plate 1 and the second hinge plate 2. First, the refrigerator door can be placed on the support plate 3 so that the first hinge shaft 4 is inserted into the refrigerator door. Then, the refrigerator door can be aligned with the placement slot 5. At this time, the second hinge shaft 6 can be inserted into the refrigerator door. Then, the adjusting shaft 13 can be rotated by the knob 15. The adjusting shaft 13 rotates inside the adjusting slot 12. The adjusting shaft 13 is threadedly connected to the transmission block 14. The transmission block 14 will move inside the adjusting shaft 13, thereby driving the second sliding cover 10 to move on the first hinge plate 1. When the second sliding cover 10 drives the pressure block 11 to move above the second hinge shaft 6, the pressure block 11 will limit the second hinge shaft 6. The second hinge shaft 6 cannot fall out of the placement slot 5. Consequently, the refrigerator cannot fall out between the first hinge plate 1 and the second hinge plate 2, thus achieving the effect of facilitating the installation of the refrigerator door.

[0026] Multiple second fixing bolts 8 are movably installed inside the first hinge plate 1, and multiple first fixing bolts 7 are movably installed on the second hinge plate 2. The first hinge plate 1 is fixedly installed on the top of the refrigerator by the second fixing bolts 8, and the second hinge plate 2 is fixedly installed on the side wall of the refrigerator by the first fixing bolts 7.

[0027] A bearing 16 is embedded in the support plate 3. The bearing 16 has a circular structure. The first hinge shaft 4 is fixedly installed inside the bearing 16. The first hinge shaft 4 is movably installed on the support plate 3 through the bearing 16. With the setting of the bearing 16, when the refrigerator door rotates, the first hinge shaft 4 will rotate inside the bearing 16, reducing the friction generated by the rotation of the refrigerator door and making the rotation of the refrigerator door smoother. A support block 17 is fixedly installed between the support plate 3 and the second hinge plate 2. The support block 17 has a triangular structure. The support block 17 can support the support plate 3 and improve the support effect of the refrigerator door.

[0028] A first sliding cover 9 is movably installed on the first hinge plate 1 at the position corresponding to the second fixing bolt 8. A sliding groove 18 is opened on the top of the first hinge plate 1 at the position corresponding to the first sliding cover 9. The sliding groove 18 is a rectangular groove, and a slider 19 is set inside the sliding groove 18. The slider 19 is fixedly connected to the first sliding cover 9. The first sliding cover 9 can slide on the first hinge plate 1. When the first hinge plate 1 is installed on the refrigerator, the first sliding cover 9 can be slid first to expose the position where the second fixing bolt 8 is installed. After the second fixing bolt 8 is installed, the first sliding cover 9 can be reset. The first sliding cover 9 can seal and protect the position where the second fixing bolt 8 is installed.

[0029] The specific working method is as follows:

[0030] By setting up a positioning mechanism, when installing the refrigerator door between the first hinge plate 1 and the second hinge plate 2, the refrigerator door can first be placed on the support plate 3 so that the first hinge shaft 4 is inserted into the interior of the refrigerator door. Then, the refrigerator door can be aligned with the placement slot 5, and the second hinge shaft 6 can be inserted into the interior of the refrigerator door. Then, the adjusting shaft 13 can be rotated by the knob 15. The adjusting shaft 13 rotates inside the adjusting slot 12, and the adjusting shaft 13 is threadedly connected to the transmission block 14. The transmission block 14 will move inside the adjusting shaft 13, thereby driving the second sliding cover 10 to move on the first hinge plate 1. When the second sliding cover 10 drives the pressure block 11 to move above the second hinge shaft 6, the pressure block 11 will limit the second hinge shaft 6, and the second hinge shaft 6 cannot fall out of the interior of the placement slot 5. Consequently, the refrigerator cannot fall out between the first hinge plate 1 and the second hinge plate 2, thus achieving the effect of facilitating the installation of the refrigerator door.
