Description

Technical Field

[0001] This utility model relates to the field of refrigerator door technology, specifically to a refrigerator door structure with good sealing effect. Background Technology

[0002] As an essential household appliance in people's daily lives, refrigerators are constantly being improved by manufacturers to better meet consumer needs in terms of functionality and appearance. Currently, refrigerators typically consist of a cabinet and a door, and magnetic door seals are usually installed at the gap between the cabinet and the door to enhance the sealing between them, prevent cold air from leaking out of the refrigerator, and reduce energy consumption.

[0003] Existing refrigerator doors typically rely on a flexible magnetic strip within a magnetic door seal for magnetic attraction. However, due to limited magnetic strength, doors often fail to close tightly or gaps appear, resulting in cold air loss and increased energy consumption. Furthermore, the magnetic door seal wears down over time, affecting its sealing performance. Since the magnetic door seal is usually fixed to the refrigerator door, replacement requires removing multiple screws, making it cumbersome. Therefore, this paper proposes a refrigerator door structure with improved sealing performance to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a refrigerator door structure with good sealing performance to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A refrigerator door structure with good sealing performance includes a refrigerator and a refrigerator door. A first limiting plate located at the edge is fixedly connected to one side of the refrigerator, and a second limiting plate located inside the first limiting plate is also fixedly connected to one side of the refrigerator. A fixing groove is provided between the first limiting plate, the refrigerator, and the second limiting plate. A fixing shell is fixedly connected to the outer side of the first limiting plate, and a connecting rod is slidably connected to the inner side of the fixing shell. A handle is fixedly connected to one end of the connecting rod, and a connecting plate located inside the fixing shell is fixedly connected to the end of the connecting rod away from the handle. Symmetrically arranged springs are fixedly connected between the fixing shell and the connecting plate. A first limiting hole is provided on one side of the first limiting plate. A fixing rod located inside the first limiting hole is fixedly connected to one end of the connecting plate away from the connecting rod. The refrigerator has a refrigerator door on the left side. A magnetic door seal is fixedly connected to one side of the refrigerator door. A first fixing hole located outside the magnetic door seal is opened on one side of the refrigerator door. A second fixing hole located inside the magnetic door seal is opened on one side of the refrigerator door. A second limiting hole is opened on one side of the magnetic door seal. A first fixing pin is provided inside the first fixing hole. One end of the first fixing pin is fixedly connected to a first fixing plate located outside the magnetic door seal. A second fixing pin is provided inside the second fixing hole. One end of the second fixing pin is fixedly connected to a second fixing plate located inside the magnetic door seal.

[0007] Preferably, the outer side of the magnetic door seal is fixedly connected with rubber protrusions, and the inner side of the handle is fixedly connected with a rubber ring.

[0008] Preferably, the number of rubber protrusions is several, and the rubber protrusions are evenly arranged in a matrix on the surface of the magnetic door seal.

[0009] Preferably, the first fixing hole and the first fixing pin are a set, and there are four sets of the first fixing hole and the first fixing pin, which are symmetrically arranged on the inside of the refrigerator door.

[0010] Preferably, the second fixing hole and the second fixing pin are a set, and there are four sets of the second fixing hole and the second fixing pin, which are symmetrically arranged on the inside of the refrigerator door.

[0011] Preferably, the first limiting hole, the second limiting hole, and the fixing rod form a set, and there are three sets of the first limiting hole, the second limiting hole, and the fixing rod. The inner dimensions of the first limiting hole and the second limiting hole are the same, and the inner dimensions of the first limiting hole and the second limiting hole are the same as the outer dimensions of the fixing rod.

[0012] Preferably, the inner shape of the fixing groove is consistent with the outer shape of the magnetic door seal, and the inner dimensions of the fixing groove are consistent with the outer dimensions of the magnetic door seal.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, through the provided components such as a refrigerator, a first limiting plate, a second limiting plate, a fixing groove, a fixing shell, a handle, a rubber ring, a connecting rod, a connecting plate, a spring, a first limiting hole, a second limiting hole, and a fixing rod, the following steps are performed: First, pulling the handle increases the comfort of gripping the handle due to the action of the rubber ring. The handle then moves the connecting rod, connecting plate, and fixing rod, causing the connecting plate to compress the spring. The fixing rod passes through the first limiting hole and is retracted into the fixing shell. Then, the refrigerator door is closed. As the refrigerator door closes, the magnetic door seal engages with the fixing groove, and simultaneously the first… The limiting hole and the second limiting hole will overlap. Then, release the handle. Under the action of the spring, the connecting plate will drive the fixing rod to pass through the first limiting hole and the second limiting hole again. The fixing rod will lock the magnetic door seal to prevent the refrigerator door from loosening. The rubber protrusions not only prevent the refrigerator door from loosening, but also improve the sealing effect between the refrigerator door and the refrigerator. This solves the problem that existing refrigerator doors generally rely on the flexible magnetic strip inside the magnetic door seal for magnetic adsorption. Due to the limited magnetic strength, the door often does not close tightly or gaps appear, resulting in the loss of cold air and increased energy consumption.

[0015] 2. In this utility model, by using components such as the refrigerator door, first fixing hole, second fixing hole, first fixing pin, second fixing pin, first fixing plate, and second fixing plate, when it is necessary to replace the magnetic door seal, simply pull the first fixing plate to pull it out of the first fixing hole along with the first fixing pin, thus separating the first fixing plate from the refrigerator door. Then, pull the second fixing plate to pull it out of the second fixing hole along with the second fixing pin, thus separating the second fixing plate from the refrigerator door. The magnetic door seal, no longer secured by the first and second fixing plates, can be easily removed. This solves the problem that due to prolonged use, the magnetic door seal will wear down, affecting the sealing effect. Generally, magnetic door seals are fixed to the refrigerator door, and replacing them requires removing multiple screws, making replacement quite troublesome. Attached Figure Description
