[0037] The present application provides a hinge fixing device and fixing method suitable for a refrigerator, so as to solve the problem that the hinge reinforcement plate adopts screws or rivets, which has a complicated process and a time-consuming and labor-consuming fixing process.

[0038] In some embodiments of the present application, a hinge fixing device suitable for a refrigerator is provided, comprising a hinge reinforcement plate 1, a threaded countersunk hole 2, a fixing buckle 3 and a fixing column 5; the hinge reinforcement plate 1 is an L-shaped structure; the threaded countersunk hole 2 is arranged on the hinge reinforcement plate 1, and the threaded countersunk hole 2 is connected to the fixing buckle 3; the fixing column 5 is fixedly connected to the hinge reinforcement plate 1; a fixing cap 6 and a groove 7 are provided on the refrigerator shell 4 of the refrigerator, and the fixing cap 6 is sleeved on the fixing column 5; the groove 7 is sleeved on the fixing buckle 3.

[0039] The hinge fixing device of the refrigerator is fixed by sleeve-fitting the fixing column 5 on the hinge reinforcing plate 1 with the fixing cap 6 on the refrigerator shell 4. The fixing buckle 3 is connected and fixed with the groove 7 on the refrigerator shell 4 and the threaded countersunk hole 2 on the hinge reinforcing plate 1 by twisting without using any auxiliary tools, so as to solve the problem that the hinge reinforcing plate is fixed with screws or rivets, which has a complicated process and is time-consuming and labor-consuming in the fixing process.

[0040] It should be understood that the hinge reinforcement plate 1, the threaded countersunk hole 2, the fixing buckle 3, the fixing column 5, the fixing cap 6 and the groove 7 are all made of rigid materials, and in some embodiments, stainless steel materials may be used.

[0041] It should be understood that the hinge reinforcement plate 1 is used to enhance the stability of the refrigerator body after foaming and the stability of the hinge and door body when the hinge on the refrigerator is fixed. The hinge reinforcement plate 1 is an L-shaped structure which will better fix the corner position of the refrigerator shell 4.

[0042] It should be understood that the threaded countersunk hole 2 is used in conjunction with the fixing buckle 3 to fix the hinge reinforcement plate 1 and the refrigerator shell 4, wherein the external thread on the threaded countersunk hole 2 and the internal thread of the fixing buckle 3 are in the same direction and have the same angle, wherein the thread direction can be left-handed or right-handed.

[0043] It should be understood that in some embodiments, the refrigerator case 4 includes two fan-shaped inclined grooves, the angle between the two sides of the fan-shaped inclined groove is 90 degrees, the inclination angle of the fan-shaped inclined groove is the same as the thread rotation angle of the threaded countersunk hole 2, and the direction is consistent. The position of the fan-shaped inclined groove is located at the rotation angle position of the center axis of the groove 7 and the groove 7.

[0044] It should be understood that in some other embodiments, the fixing column 5 and the hinge reinforcement plate 1 are an integrally formed structure. The integrally formed structure will reduce the connection gap between the fixing column 5 and the hinge reinforcement plate 1, making the connection tight and uniform, increasing the force strength, and not easy to crack.

[0045] In some embodiments, the fixing cap 6 and the refrigerator shell 4 are integrally formed. The integrally formed structure reduces the connection gap between the fixing cap 6 and the refrigerator shell 4, making the connection tight and uniform, increasing the force strength, and not easy to crack. In addition, the integrally formed structure can improve the structure of the refrigerator assembled from multiple parts, simplifying the connection structure of the refrigerator and simplifying the production process.

[0046] In some embodiments, the fixing buckle 3 includes an outer plate 31 and a threaded column 32; the outer plate 31 is fixedly connected to the threaded column 32; the threaded column 32 is threadedly connected to the threaded countersunk hole 2. The threaded column 32 can be threadedly connected to the threaded countersunk hole 2 by rotating the outer plate 31, without the need for additional pneumatic or electric equipment, which is more convenient, faster, time-saving and labor-saving.

[0047] It should be understood that, in some embodiments, the threaded column 32 and the interior of the threaded countersunk hole 2 may be cylindrical structures. When the threaded column 32 and the interior of the threaded countersunk hole 2 are cylindrical structures, the external thread on the threaded countersunk hole 2 and the internal thread of the threaded column 32 are quarter-turn threads, which is simpler and more convenient for fixation. In other embodiments, the threaded column 32 and the interior of the threaded countersunk hole 2 may be conical structures. When the threaded column 32 and the interior of the threaded countersunk hole 2 are conical structures, the external thread on the threaded countersunk hole 2 and the internal thread of the threaded column 32 are multiple starting quarter-turn threads, which is not only simple and convenient for fixation, but also more secure.

[0048] In some embodiments, the refrigerator case 4 further includes a clearance hole, which is provided on the refrigerator case 4; the outer plate 31 is snap-fitted with the clearance hole; the length of the threaded column 32 is greater than the sum of the depths of the clearance hole and the threaded countersunk hole 2; the hole pitch of the clearance hole is not less than the hole pitch of the threaded countersunk hole 2. The clearance hole is not only used for blanking in the stamping die when the refrigerator case 4 is manufactured, but also the threaded column 32 can pass through the clearance hole to connect the refrigerator case 4 with the hinge reinforcement plate 1, thereby playing a role of tight connection and fixation.

[0049] In some embodiments, the inner size of the groove 7 is the same as that of the outer plate 31, the clearance hole is located inside the groove 7, and the groove 7 and the clearance hole are sleeved with the fixing buckle 3. The groove 7 protects the surface of the outer plate 31 from being damaged by bumps and further positions it.

[0050] In some embodiments, the outer plate 31 is a rectangular structure, and the interior of the groove 7 is a rectangular structure. The outer plate 31 with a rectangular structure is more convenient to rotate and apply force on one hand, and has a larger force-bearing area and is more securely fixed on the other hand; the groove 7 is also a rectangular structure, and the outer plate 31 is finally rotated into the groove 7, so that the surface of the refrigerator shell 4 fixed with the hinge reinforcement plate 1 is smoother, and the outer plate 31 is not easily damaged due to bumps and other reasons.

[0051] In some embodiments, the refrigerator case 4 further includes an S-shaped buckle 9; the S-shaped buckle 9 is located at the outer edge of the refrigerator case 4, and the S-shaped buckle 9 is engaged with the hinge reinforcement plate 1. The engagement of the S-shaped buckle 9 with the hinge reinforcement plate 1 reduces the probability of movement of the fixing buckle 3 during rotation, thereby further fixing the hinge reinforcement plate 1.

[0052] It should be understood that the S-shaped buckle 9 includes a fixed end and a movable end. By controlling the opening and closing of the movable end of the S-shaped buckle 9, the S-shaped buckle 9 is combined with the fixed column 5 to further adjust the positioning of the refrigerator shell 4 and the hinge reinforcement plate 1, so that the probability of movement of the fixing buckle 3 during rotation is reduced.

[0053] In some embodiments, the hinge reinforcement plate 1 further comprises at least one fixing hole 8; the fixing hole 8 is connected to the hinge of the refrigerator. The fixing hole 8 is used to connect and fix the hinge reinforcement plate 1 to the hinge of the refrigerator, in order to enhance the stability of the refrigerator body and the stability of the hinge and the door body when the hinge on the refrigerator is fixed.

[0054] The present application also provides a hinge fixing method for a refrigerator in some other embodiments, which is applied to the hinge connecting device for a refrigerator described in the above embodiments, such as Figure 7 As shown, the fixing method comprises:

[0055] S100: Connecting the hinge reinforcement plate 1 and the refrigerator shell 4 to each other; wherein the fixing column 5 is sleeved with the fixing cap 6 to position the hinge reinforcement plate 1 at the desired position of the refrigerator shell 4;

[0056] S300: Arrange the fixing buckle 3 above the groove 7 so that the outer plate 31 of the fixing buckle 3 and the central axis of the groove 7 are perpendicular to each other;

[0057] S400: With the central axis of the groove 7 as the rotation axis, the fixing buckle 3 is rotated 90 degrees according to the thread direction of the threaded column 32 to fix the hinge reinforcement plate 1 on the refrigerator shell 4.

[0058] The method enables the fixing reinforcement plate to be fixed to the refrigerator housing without using any auxiliary tools, thereby solving the problem that the fixing process of the hinge reinforcement plate using screws or rivets is complicated and the fixing process is time-consuming and labor-intensive.

[0059] In some embodiments, Figure 7 As shown, the fixing method further comprises:

[0060] S200: The S-shaped buckle 9 is engaged with the hinge reinforcement plate 1 to further position the hinge reinforcement plate 1 and the refrigerator shell 4.
