Description

Technical fields:

[0001] This invention relates to a refrigerator drawer seal-free support structure and a refrigerator, which belongs to the field of household appliance technology. Background technology:

[0002] Existing refrigerator drawers slide within slide rails and are supported in the following three ways:

[0003] 1. Rollers: High cost;

[0004] 2. The support columns are fixed to the foaming box with self-tapping screws, resulting in low production efficiency;

[0005] 3. Support columns are fixed to the inner liner of the box using mounting brackets, which results in low production efficiency and high cost.

[0006] Therefore, it is indeed necessary to improve existing technologies to address their shortcomings. Summary of the Invention:

[0007] The present invention provides a low-cost, high-production-efficiency, and high-reliability refrigerator drawer seal-free support structure and refrigerator in order to solve the problems existing in the prior art.

[0008] The present invention adopts the following technical solution: a refrigerator drawer seal-free support structure, installed on the refrigerator liner, including an integrally formed tightening structure, a support structure, and a connecting structure located between the tightening structure and the support structure. The outer surface of the tightening structure protrudes outward to form a wing, the wing being spaced apart from the connecting structure, and a locking point forming at the end of the wing. A through hole is formed on the refrigerator liner for the tightening structure to pass through, the through hole including a locking hole for the wing to pass through and communicating with the through hole. A protrusion assembly is formed on the refrigerator liner at the outer edge of the through hole. After the tightening structure passes through the through hole, it is located in the refrigerator foam layer on the outer side of the refrigerator liner. Rotating the tightening structure causes the locking point to be secured in the protrusion assembly.

[0009] Furthermore, the wing edge includes two symmetrically arranged parts, the locking hole includes two vertically arranged parts, and the protrusion assembly is located between the locking holes and includes two symmetrically arranged parts.

[0010] Furthermore, the connecting structure is stepped, comprising a first plate connected to the tightening structure and a second plate connected to the supporting structure, wherein the diameter of the first plate is smaller than the diameter of the second plate.

[0011] Furthermore, the inner side of the refrigerator liner is recessed to form a stepped groove that matches the connecting structure.

[0012] Furthermore, the tightening structure includes an internally hollow cylindrical body, and the wing edge is formed by protruding outward from the outer surface of the cylindrical body.

[0013] Furthermore, the support structure is also in the shape of a hollow cylinder.

[0014] Furthermore, each set of the bump assembly includes two bumps spaced apart.

[0015] The present invention also adopts the following technical solution: a refrigerator, including the refrigerator drawer seal-free support structure described in any one of the preceding claims.

[0016] The present invention has the following beneficial effects:

[0017] (1) The refrigerator drawer seal-free support structure of the present invention uses a screw-tightening structure, which ensures convenient assembly and can fit tightly with the refrigerator liner. The screw-tightening structure has wing edges on both sides to ensure the contact area with the foam material and increase the weight that can be supported.

[0018] (2) The refrigerator liner of the present invention is provided with a through hole, so as to ensure that the screwing structure passes through the refrigerator liner. At the same time, the screwing structure can be installed in place by the cooperation of the locking point and the protrusion.

[0019] (3) The connecting structure is closely attached to the inner side of the refrigerator liner. When the foam layer is poured on the outside of the refrigerator liner, it can prevent the bubbles from escaping, achieve sealing-free operation, and improve production efficiency.

[0023] Figure 4 This is a schematic diagram of the screw-on structure after it has been locked. Detailed implementation method:

[0024] The invention will now be further described with reference to the accompanying drawings.

[0025] This invention discloses a refrigerator drawer seal-free support structure, which is installed on the refrigerator liner 4. It includes an integrally formed tightening structure 1, a support structure 2, and a connecting structure 3 located between the tightening structure 1 and the support structure 2. The connecting structure 3 is stepped and includes a first plate 30 connected to the tightening structure 1 and a second plate 31 connected to the support structure 2, wherein the diameter of the first plate 30 is smaller than the diameter of the second plate 31. The tightening structure 1 includes a hollow cylindrical body 10 and two symmetrically arranged fins 11 protruding outward from the outer surface of the cylindrical body 10, spaced apart from the first plate 30. A locking point 110 is formed on the end of the fins 11 away from the cylindrical body 10.

[0026] Support structure 2 is also in the shape of a hollow cylinder.

[0027] The refrigerator liner 4 has a through hole 40 for the screw-on structure 1 to pass through. The through hole 40 includes a locking hole 41 for the fin 11 to pass through and which is in communication with the through hole 40. Two symmetrically arranged protrusion assemblies 42 are formed on the refrigerator liner 4 at a position on the outer side of the outer edge of the through hole 40 and between the two locking holes 41. Each protrusion assembly 42 includes two protrusions spaced apart.

[0028] When the refrigerator drawer seal-free support structure of the present invention is installed on the refrigerator liner 4, the support structure 2 is supported below the drawer guide rail of the refrigerator drawer, and the wing edge 11 on the tightening structure 1 is aligned with the locking hole 41, so that the tightening structure 1 can pass through the through hole 40 in the refrigerator foam layer on the outside of the refrigerator liner 4. Then, the tightening structure 1 is rotated so that the locking point 110 is locked between the two protrusions in each protrusion assembly 42, and the connecting structure 3 is tightly attached to the stepped groove (not shown) formed on the inner side of the refrigerator liner 4, so that the refrigerator drawer seal-free support of the present invention is securely installed on the refrigerator liner 4.

[0029] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be considered within the scope of protection of the present invention.
