Description

Technical fields:

[0001] This utility model relates to a composite extruded decorative strip for refrigerator and freezer glass, which belongs to the field of household appliance technology. Background technology:

[0002] Currently, refrigerators and freezers commonly use glass doors to enhance aesthetics and product quality. Glass doors are typically secured and decorated with extruded plastic trim around the edges. Traditional trims are mostly made of a single material, plastic, which has the following drawbacks:

[0003] 1. Installation reliability issues: In order for the decorative strip made of a single rigid material to be inserted into the box, its size must leave a gap with the installation groove, which may cause wobbling, instability, or even abnormal noise due to transportation vibration after installation.

[0004] 2. Risk of glass damage: Glass is a brittle material. When hard decorative strips come into direct contact with and are squeezed against the glass surface, there is a risk of crushing or scratching the glass due to stress concentration, especially when the installation is subjected to uneven force or impact.

[0005] 3. Insufficient sealing and cushioning: A single rigid material cannot provide effective elastic cushioning and sealing, which may lead to the intrusion of condensed water vapor or the inability to effectively absorb vibration.

[0006] While existing technologies allow for the separate application of soft adhesive strips to rigid decorative strips, this process is complex, increasing production steps and costs. Furthermore, the applied adhesive strips are susceptible to aging and detachment, affecting product lifespan and aesthetics. Other methods employ gluing, but hot melt adhesives or other types of adhesives can fail under the high temperature and humidity conditions of sea transport, posing a risk of detachment.

[0007] Therefore, it is indeed necessary to improve existing technologies to address their shortcomings. Utility Model Content:

[0008] This invention provides a composite extruded decorative strip for refrigerator and freezer glass to solve the problems existing in the prior art. It can ensure installation strength, protect the glass, and improve installation reliability.

[0009] The present invention adopts the following technical solution: a composite extruded decorative strip for refrigerator and freezer glass, comprising a base portion, the base portion comprising a main body portion, a bent portion formed by bending from the middle position of the width direction of the main body portion, an installation groove formed between the bent portion and the main body portion, and a lip portion protruding from the position of the main body portion in the installation groove.

[0010] Furthermore, a snap-fit ​​portion is formed by bending one end of the main body portion in the width direction, and the bending direction of the snap-fit ​​portion is consistent with that of the bent portion.

[0011] Furthermore, the base portion is made of ABS material through extrusion molding.

[0012] Furthermore, the lip portion is made of thermoplastic elastomer material.

[0013] Furthermore, the lip portion extends from the side of the base portion.

[0014] Furthermore, the number of the lip portion can be one or more.

[0015] Furthermore, the lip portion is a solid or hollow structure.

[0016] This utility model has the following beneficial effects:

[0017] (1) Reliable installation and elimination of abnormal noise: The elastic deformation of the soft lip provides continuous clamping force, making the decorative strip fit tightly with the glass, eliminating installation gaps, and effectively preventing loosening and vibration noise.

[0018] (2) Effective protection of glass: The soft material serves as the contact medium, and the stress distribution is uniform, avoiding stress concentration caused by point contact or line contact, which greatly reduces the risk of crushing or scratching the glass.

[0019] (3) Sealing, dustproof and moistureproof: The elastic contact surface forms a good seal, which can prevent dust and moisture from entering the gap between the glass and the decorative strip, keeping the interior clean and dry.

[0020] (4) Simple process and stable structure: It is formed in one step through co-extrusion technology, which has high production efficiency and low cost. The soft and hard materials are firmly bonded at the molecular level, avoiding the risk of falling off caused by secondary bonding and glue application processes, and the product has a long life.

[0021] (5) Beautiful and elegant: The one-piece molding structure is simple and the appearance is seamless, making it more aesthetically pleasing. Attached image description:

[0023] Figure 2 This is a schematic diagram showing the application of the composite extruded decorative strip of the refrigerator and freezer glass of this utility model to a refrigerator. Detailed implementation method:

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

[0025] This utility model relates to a composite extruded decorative strip for refrigerator and freezer glass. The strip is an elongated extruded part, comprising a base portion 1, which includes a main body portion 10. A snap-fit ​​portion 100 is formed by bending one end of the main body portion 10 in the width direction, and a bent portion 101 is formed by bending from the middle of the main body portion 10 in the width direction. The bending directions of the snap-fit ​​portion 100 and the bent portion 101 are consistent. A mounting groove 102 is formed between the bent portion 101 and the main body portion 10, and a lip portion 2 protrudes from the main body portion 10 within the mounting groove 102.

[0026] The base part 1 is made of ABS material through extrusion molding, which constitutes the main framework and appearance of the decorative strip. The rigid base part 1 ensures that the entire decorative strip will not twist or deform during installation and use, maintaining the stability of its overall shape.

[0027] The lip portion 2 is made of thermoplastic elastomer (TPO) material, which achieves a strong molecular bond with the rigid matrix portion 1 during the co-extrusion molding process.

[0028] The lip portion 2 is designed as a lip-shaped sealing strip structure, extending from the side of the base portion 1. The lip portion 2 is made of a soft and elastic material, forming an elastic contact surface that comes into contact with the surface of the refrigerator glass panel. This soft lip portion 2 protrudes slightly in its natural state, and undergoes elastic deformation under the pressure of the glass during installation, thereby generating a continuous clamping force and cushioning effect.

[0029] The lip portion 2 can be a single lip, multiple lips, solid, or hollow structures of different shapes.

[0030] This invention relates to a composite extruded decorative strip for refrigerator and freezer glass. During installation, the glass plate 3 is aligned, and then the composite extruded decorative strip is pressed into the glass from the side. Initially, the soft lip 2 contacts the surface of the glass plate 3. As pressing continues, the soft lip 2 is compressed and undergoes elastic deformation. The deformed lip 2 generates a reverse elastic restoring force, acting like a spring, continuously and evenly pressing against the surface of the glass plate 3, forming an elastic contact surface. This invention cleverly utilizes a one-piece structure combining soft and hard components to simultaneously satisfy the seemingly contradictory needs of "secure installation" and "glass protection." The soft part is responsible for contact, cushioning, and sealing, while the hard part is responsible for support, fixation, and shape maintenance. Working together, they achieve optimal performance.

[0031] The above description is merely a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
