Description

Technical Field

[0001] This utility model belongs to the field of refrigerator door seal technology, and more specifically, it relates to a spring structure of a refrigerator door seal anti-tangle energy-saving component. Background Technology

[0002] Refrigerator door seals are the core sealing components that maintain the low-temperature environment inside the refrigerator. They achieve isolation between the inside and outside of the refrigerator through magnetic adsorption and elastic deformation, directly affecting the refrigerator's energy efficiency and lifespan. Refrigerator door seal anti-tangling energy-saving components are functional accessories installed in key positions on the refrigerator door seals. Their core function is to reduce tangling, friction, and wear of the door seals during the opening and closing process through structural design, while also helping to enhance the sealing performance of the door seals, indirectly achieving energy savings for the refrigerator.

[0003] Current anti-winding and energy-saving components still have the following shortcomings: Current anti-tangle energy-saving components lack a buffer mechanism. The rigid contact between the door seal and the anti-tangle structure can easily aggravate wear and affect service life. Moreover, they do not have an active rebound function, which cannot help the door seal to quickly restore its flatness after the door is opened. Residual wrinkles can easily lead to poor sealing. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a spring-loaded structure for a refrigerator door seal anti-tangle energy-saving component. This solves the problems mentioned in the background art, such as the lack of a buffer mechanism in current anti-tangle energy-saving components, the rigid contact between the door seal and the anti-tangle structure easily aggravating wear and affecting service life, and the lack of an active spring-loaded function, which cannot help the door seal quickly return to flatness after opening the door, and the residual wrinkles easily leading to poor sealing.

[0005] The purpose and effect of the rebound structure of the refrigerator door seal anti-tangle energy-saving component of this utility model are achieved by the following specific technical means: A spring-loaded structure for an anti-tangle energy-saving refrigerator door seal includes: a mounting plate; the mounting plate adopts a rectangular frame structure, and a set of arc-shaped groove structures are provided on both the upper and lower sides of the mounting plate, and a set of rectangular groove structures are provided on both the upper and lower sides of the front wall of the mounting plate; a storage groove with a rectangular groove structure is fixedly provided on the inner side of the mounting plate, and a set of arc-shaped groove structures are provided on both the upper and lower sides of the front wall of the storage groove; a contact block with a conical block structure is slidably provided on the front side of the storage groove, and the front side of the contact block adopts an arc structure, and the rear two sides of the contact block have inclined structures, and the contact block is made of silicone material.

[0006] Furthermore, a set of U-shaped block structure limiting plates are rotatably connected in the arc-shaped grooves on both the upper and lower sides of the mounting plate, and the rear wall of the limiting plate is in contact with the front wall of the arc-shaped groove on the mounting plate; a worm gear is fixedly installed at the front end of the rotating shaft of the limiting plate.

[0007] Furthermore, a worm gear is rotatably installed in the arc-shaped groove on the front side of the mounting plate, and the worm gear is meshed with a worm wheel; a cylindrical roller is fixedly installed at the top of the worm gear, and an arc-shaped anti-slip groove is opened on the outer side of the roller, and the roller is installed in the rectangular groove on the front wall of the mounting plate.

[0008] Furthermore, a rectangular plate structure is fixedly installed on the inner side of the storage slot, and a set of through circular slot structures are opened on both sides of the fixed plate; a set of cylindrical sliding rods are slidably installed in the circular slots on both sides of the fixed plate, and springs are sleeved on the outer side of the sliding rods, and contact blocks are fixedly connected to the front ends of the two sets of sliding rods.

[0009] Compared with the prior art, the present invention has the following beneficial effects: In this application, the arc-shaped structure on the front side of the contact block makes flexible contact with the door seal, and the elastic deformation of the silicone material can disperse the stress when the door seal is squeezed and reduce hard friction; the spring on the outside of the slide rod provides continuous reset elastic force for the contact block: when the door is closed, the spring is compressed to store potential energy, and when the door is opened, the potential energy is released to push the contact block to reset, causing the door seal to return to its natural extended state; the inclined structure on both sides of the contact block assists in pushing the door seal to unfold during the reset process, avoiding wrinkles and ensuring a tight seal when closed again.

[0010] The angle adjustment function of the limiting plate also enables quick assembly and disassembly of the storage slot and the mounting plate: simply rotate the roller to fix or disassemble, which facilitates the maintenance and replacement of the rebound components (such as springs and contact blocks) in the later stage. The operation is simple and efficient. The sliding fit between the slide rod and the fixing plate, and the inclined guide between the contact block and the storage slot, ensure the stability of the overall structure and avoid functional failure caused by deviation during the rebound process.

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0018] Example 1: As shown in the attached document Figure 1 To be continued Figure 5 As shown: This utility model provides a spring-loaded structure for a refrigerator door seal anti-tangle energy-saving component, comprising: a mounting plate 1; the mounting plate 1 adopts a rectangular frame structure, and a set of arc-shaped groove structures are provided on both the upper and lower sides of the mounting plate 1, and a set of rectangular groove structures are provided on both the upper and lower sides of the front wall of the mounting plate 1; a rectangular groove structure storage groove 105 is fixedly provided on the inner side of the mounting plate 1, and a set of arc-shaped groove structures are provided on both the upper and lower sides of the front wall of the storage groove 105; a conical block structure contact block 108 is slidably provided on the front side of the storage groove 105, and the front side of the contact block 108 adopts an arc structure, and the rear two sides of the contact block 108 are provided with inclined structures. The contact block 108 is made of silicone material and has elastic buffering capability.

[0019] The storage slot 105 has a rectangular plate fixed plate 106 fixedly installed on its inner side, and a set of through circular slots is opened on both sides of the fixed plate 106. A set of cylindrical slide rods 107 are slidably installed in the circular slots on both sides of the fixed plate 106, and springs are sleeved on the outer side of the slide rods 107. The front ends of the two sets of slide rods 107 are fixedly connected to contact blocks 108. The two ends of the springs abut against the fixed plate 106 and the contact blocks 108 respectively, providing a reset elastic force for the contact blocks 108.

[0020] The specific usage and function of this embodiment are as follows: As the refrigerator door gradually closes, the side or corner transition surface of the door seal gradually approaches the contact block 108, eventually contacting the arc-shaped structure on the front side of the contact block 108. As the door continues to close, the door seal applies forward pressure to the contact block 108, forcing the contact block 108 to slide inward along the storage groove 105, while simultaneously driving the slide rod 107 to slide synchronously within the circular through groove of the fixing plate 106, compressing the spring on the outer side of the slide rod 107. During this process, the inclined surface behind the contact block 108 always slides along the arc-shaped groove on the front wall of the storage groove 105, ensuring that the contact block 108... 8 moves only along the axial direction without shifting, while the silicone material of the contact block 108 undergoes slight deformation due to pressure, buffering the impact force of the door seal. When the refrigerator door is opened, the pressure of the door seal on the contact block 108 gradually decreases until it disappears. At this time, the spring on the outside of the slide bar 107 releases the stored elastic potential energy, pushing the contact block 108 to slide forward along the storage groove 105. The slide bar 107 resets synchronously with the contact block 108. The inclined structure on both sides of the contact block 108 assists in pushing the door seal open, assisting the door seal to return to its natural extended state, and preventing the door seal from being deformed.

[0021] Example 2: Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 5 As shown: Among them, a set of U-shaped block structure limiting plates 101 are rotatably connected in the arc-shaped grooves on the upper and lower sides of the mounting plate 1, and the rear wall of the limiting plate 101 is in contact with the front wall of the arc-shaped groove on the mounting plate 1, and the angle can be adjusted by rotating along the arc-shaped groove; a worm gear 102 is fixedly provided at the front end of the rotating shaft of the limiting plate 101.

[0022] A worm gear 103 is rotatably mounted in the arc-shaped groove on the front side of the mounting plate 1, and the worm gear 103 is meshed with a worm wheel 102. The angle of the limiting plate 101 is adjusted by the meshing of the worm wheel 102 and the worm gear 103. A cylindrical roller 104 is fixedly mounted at the top of the worm gear 103, and an arc-shaped anti-slip groove is provided on the outer side of the roller 104. The roller 104 is located in a rectangular groove on the front wall of the mounting plate 1. By rotating the roller 104, the worm gear 103 can be driven to rotate, thereby driving the limiting plate 101 to rotate.

[0023] The specific usage and function of this embodiment are as follows: In this invention, the mounting plate 1 is installed on the anti-tangle energy-saving component, and a rectangular groove structure matching the storage slot 105 is opened on the anti-tangle energy-saving component. The storage slot 105 is installed on the inner side of the mounting plate 1, so that the arc-shaped grooves on the upper and lower sides of the storage slot 105 are aligned with the positions of the arc-shaped grooves on the upper and lower sides of the mounting plate 1. The anti-slip groove on the outer side of the roller 104 is rubbed with a finger and rotated, and the roller 104 drives the worm gear 103 to rotate in the arc-shaped groove of the mounting plate 1. Since the worm gear 103 meshes with the worm wheel 102, the worm wheel 102 rotates with the worm gear 103. The rotation of roller 104 causes the limiting plate 101 to rotate around its axis within the arc-shaped groove of the mounting plate 1. By controlling the rotation direction and angle of roller 104, the rotation angle of limiting plate 101 can be adjusted so that limiting plate 101 can synchronously fit with the coin in the arc-shaped groove of mounting plate 1 and storage slot 105, thereby fixing storage slot 105 in the mounting plate 1 and completing the installation process of storage slot 105. When maintenance or repair is required, disassembly can be performed by following the reverse steps. Disassembly is quick and convenient, and easy to operate and use.
