Description

Technical Field

[0001] This utility model relates to the field of freezer door technology, and more specifically, to a freezer door spring structure. Background Technology

[0002] In the field of refrigeration equipment, freezers are essential home appliances for food preservation and storage, and their performance directly affects the user experience and the effectiveness of storage. The sealing and smoothness of the freezer door's opening and closing largely depend on the design of the hinge spring structure.

[0003] The spring structure in traditional freezer door hinges has a fixed elasticity during manufacturing, which cannot be adjusted according to actual usage needs. During long-term and repeated use of the freezer door, the spring will fatigue due to frequent opening and closing, causing the elasticity to gradually weaken. This results in the freezer door not sealing properly when closed, allowing cold air to leak out, which not only increases the freezer's energy consumption but also affects the preservation effect of the items inside. Summary of the Invention

[0004] Based on the aforementioned spring structure in traditional freezer door hinges, the spring force is fixed during manufacturing and cannot be adjusted according to actual usage needs. During long-term, repeated use of the freezer door, the spring will fatigue due to frequent opening and closing, causing the spring force to gradually weaken. This results in a poor seal when the freezer door is closed, leading to cold air leakage, which not only increases the freezer's energy consumption but also affects the preservation effect of the contents. To address this technical problem, this utility model proposes a freezer door spring structure.

[0005] The present invention proposes a refrigerator door spring structure, comprising a rod sleeve, a screw, a spring, and a threaded sleeve;

[0006] The outer wall of the sleeve is slidably connected to a connector;

[0007] A connector is fixedly connected to the top of the screw, a retaining ring is fixedly connected to the outer wall of the connector, and multiple connecting arms are fixedly connected to the bottom of the retaining ring. The connecting arms are fixedly installed on the connector.

[0008] The spring is fitted onto the rod sleeve, and the spring is located above the connector;

[0009] The threaded sleeve is threadedly connected to the screw. A baffle is rotatably connected to the outer peripheral wall of the threaded sleeve through a bearing. The baffle is located between two adjacent connecting arms and is slidably connected to them. The baffle is located above the spring.

[0010] Preferably, the connector includes a sliding sleeve, the bottom of the inner wall of the sliding sleeve is provided with a sliding hole, and the end of the rod sleeve passes through the sliding hole and is slidably connected thereto.

[0011] Preferably, a connecting disc is slidably fitted onto the inner wall of the sleeve, and the top of the connecting disc is fixedly connected to multiple connecting arms.

[0012] Preferably, the top of the connecting plate has multiple second screw holes, and the bottom of the inner wall of the sliding sleeve has multiple first screw holes, with bolts threaded into the second screw holes.

[0013] Preferably, the end of the bolt passes through the corresponding first threaded hole below and is threaded to it, and a nut is threaded to the outer wall of the bolt, with the top of the nut making contact with the bottom of the sliding sleeve.

[0014] Preferably, a limiting plate is fixedly connected to the bottom of the rod sleeve, and the limiting plate has an arc-shaped structure.

[0015] Preferably, the top of the sleeve has a sliding cavity, the bottom end of the screw extends into the sliding cavity, and a slider is fixedly connected to the bottom of the screw, the slider being slidably connected to the inner wall of the sliding cavity.

[0016] Preferably, a connector is fixedly connected to the top of the screw, a connecting groove is provided on the top of the connector, and a connecting block is fixedly connected to the inner wall of the connecting groove.

[0017] The beneficial effects of this utility model, achieved through the above technical solution, are as follows:

[0018] Traditional spring structures have a fixed elasticity, which can lead to poor sealing of the freezer door due to spring fatigue during use. In this device, the threaded connection between the threaded sleeve and the screw, combined with the compression action of the baffle on the spring, enables adjustable spring force. When the spring becomes fatigued and its elasticity weakens due to frequent opening and closing, the user does not need to replace the spring; simply rotating the threaded sleeve adjusts the spring's compression level to restore its elasticity. This design allows the freezer door spring structure to adapt to the needs of long-term, repeated use, ensuring that the freezer door maintains a good seal when closed, effectively reducing cold air leakage, lowering freezer energy consumption, and improving the preservation effect of the contents.

[0026] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] In this utility model, unless otherwise explicitly specified and limited, the term "fixed connection" should be interpreted broadly. For example, "fixed connection" can mean fixed installation, detachable connection, or integral connection; it can mean mechanical connection or electrical connection; it can mean direct connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, a refrigerator door spring structure includes a rod sleeve 1, a screw 10, a threaded sleeve 15, and a spring 16. A connector is slidably connected to the outer wall of the rod sleeve 1. A connector 9 is fixedly connected to the top of the screw 10. A fixing ring 13 is fixedly connected to the outer wall of the connector 9. Multiple connecting arms 14 are fixedly connected to the bottom of the fixing ring 13. The connecting arms 14 are fixedly installed on the connector.

[0029] Spring 16 is fitted onto rod sleeve 1. Spring 16 is located above the connector. Threaded sleeve 15 is threadedly connected to screw 10. Baffle 151 is rotatably connected to the outer peripheral wall of threaded sleeve 15 via bearing. Baffle 151 is located between two adjacent connecting arms 14 and is slidably connected to them. Baffle 151 is located above spring 16.

[0030] Traditional refrigerator door hinges have springs whose elasticity is fixed during manufacturing and cannot be adjusted according to actual usage needs. Over long-term, repeated use, the springs fatigue due to frequent opening and closing, causing the elasticity to gradually weaken. This results in a poor seal when the refrigerator door is closed, leading to cold air leakage, increasing energy consumption, and affecting the preservation of the contents. In this device, the elasticity of spring 16 is adjusted by rotating the threaded sleeve 15. Even when spring 16 fatigues and its elasticity weakens, it can be adjusted promptly to ensure a good seal when the refrigerator door is closed, reducing cold air leakage, lowering energy consumption, and preserving the freshness of the contents.

[0031] In this embodiment, as Figure 5 and Figure 6 As shown, the connector includes a sliding sleeve 3. A sliding hole 301 is provided at the bottom of the inner wall of the sliding sleeve 3. The end of the rod sleeve 1 passes through the sliding hole 301 and is slidably connected to it. A connecting plate 4 is slidably fitted on the inner wall of the sliding sleeve 3. The top of the connecting plate 4 is fixedly connected to multiple connecting arms 14. Multiple second screw holes 6 are provided at the top of the connecting plate 4. Multiple first screw holes 5 are provided at the bottom of the inner wall of the sliding sleeve 3. A bolt 7 is threadedly connected to the second screw hole 6. The end of the bolt 7 passes through the corresponding first screw hole 5 below and is threadedly connected to it. A nut 8 is threadedly connected to the outer wall of the bolt 7. The top of the nut 8 is pressed against the bottom of the sliding sleeve 3.

[0032] In this embodiment, as Figure 5 As shown, a limiting plate 2 is fixedly connected to the bottom of the rod sleeve 1, and the limiting plate 2 has an arc structure.

[0033] In this embodiment, as Figure 3 As shown, a sliding cavity is provided at the top of the sleeve 1, and the bottom end of the screw 10 extends into the sliding cavity. A slider 1001 is fixedly connected to the bottom of the screw 10, and the slider 1001 is slidably connected to the inner wall of the sliding cavity. The design of the slider 1001 and the sliding cavity provides a stable guide for the adjustment force of the spring 16 by the threaded sleeve 15, ensuring that the screw 10 will not deviate or wobble during the adjustment process, thus improving the accuracy and stability of the spring force adjustment.

[0034] In this embodiment, as Figure 1 and Figure 2 As shown, a connector 9 is fixedly connected to the top of the screw 10. A connecting groove 11 is opened on the top of the connector 9. A connecting block 12 is fixedly connected to the inner wall of the connecting groove 11. The connecting block 12 is movably connected to one page of the refrigerator door hinge. The rod sleeve 1 is movably installed on the other page. When the hinge pages rotate relative to each other, the spring 16 is compressed and generates elastic force.

[0035] Working principle: When installing the refrigerator door spring structure, first pass the rod sleeve 1 through the sliding hole 301 at the bottom of the sliding sleeve 3. Then, put the connecting plate 4 into the sliding sleeve 3, and pass the bolt 7 through the second screw hole 6 and the first screw hole 5 in sequence, and tighten it with the nut 8 to fix the connecting plate 4 to the sliding sleeve 3.

[0036] When it is necessary to adjust the elasticity of spring 16, rotate threaded sleeve 15. Since threaded sleeve 15 is threadedly connected to screw 10, it will move up and down along screw 10 when rotated. By squeezing or releasing spring 16 through baffle 151, the telescopic length of spring 16 can be adjusted, thereby adjusting the elasticity of spring 16. During the opening and closing of the freezer door, spring 16 provides elasticity to assist the freezer door in closing. When spring 16 becomes fatigued due to frequent use and the elasticity weakens, the elasticity can be adjusted again by rotating threaded sleeve 15 to maintain good sealing after the freezer door is closed.
