Description

Technical Field

[0001] This application relates to the field of glass door panel installation technology, and in particular to an embedded glass screw fixing structure. Background Technology

[0002] Refrigeration equipment, such as refrigerators and wine coolers, is widely used in daily life and commercial settings. In supermarkets and convenience stores, refrigerators are used to display various fresh foods and beverages, while wine coolers provide chilled drinks for bars and restaurants. Traditional refrigeration equipment doors often feature framed designs, typically made of plastic or metal. The presence of frames increases manufacturing costs, including material and installation costs. Furthermore, frames can obstruct the view, affecting the display of items inside, especially in commercial spaces where prominent product displays are crucial. In recent years, frameless glass doors have become increasingly popular. Frameless glass doors eliminate traditional frames, resulting in a simpler, more stylish appearance that blends better with various interior design styles. Simultaneously, the frameless design significantly increases the visible area, allowing consumers to see the displayed goods more comprehensively, enhancing the product display and boosting sales.

[0003] However, frameless glass door panels face significant technical challenges during installation. Due to the inherent brittleness of glass, its impact resistance and ability to withstand localized pressure are relatively weak. If the traditional installation method of framed door panels—directly fixing the glass door panel with screws—is used, the localized compressive force generated when the screws are tightened will quickly concentrate in the glass area around the screw holes. The interior of the glass door panel cannot effectively disperse this instantaneous pressure, which can easily lead to cracks at stress concentration points. As the screw tightening force increases, the cracks will rapidly extend, eventually causing the glass door panel to break. Therefore, how to achieve frameless installation of glass door panels on refrigeration equipment has become a key bottleneck restricting its large-scale application. Utility Model Content

[0004] This device provides an embedded glass screw fixing structure, the specific implementation of which is as follows:

[0005] An embedded glass screw fixing structure includes:

[0006] Double-layered glass door panel, with a hollow layer formed inside the double-layered glass door panel;

[0007] Several fasteners are built into the hollow layer, with both ends of the fasteners abutting against the two sides of the hollow layer, and the center of the fasteners is set as a hollow internal threaded cylinder;

[0008] The glass screw has its external thread connected to the internal threaded cylinder and then to the main body of the equipment. After installation, the glass screw is countersunk on the outer surface of the double-layer glass door panel.

[0009] Based on the above technical solutions, to address the installation pain point of frameless glass door panels being prone to breakage when directly screwed in, a double-layer glass door panel structure is adopted. A fastener made of metal or high-strength engineering plastic, preferably transparent plastic, is pre-embedded in the hollow layer between the two layers of glass. This fastener needs to be embedded simultaneously during the processing of the double-layer glass panels, tightly bonding with the glass layers to form a stable integrated structure. Thus, the internal thread structure is pre-laid before the double-layer glass door panel is fully formed. In the subsequent installation stage, screws are simply aligned with the corresponding threaded holes of the fasteners on the outer glass of the door panel and screwed in. The tightening force of the screws is directly transferred to the pre-embedded fasteners, rather than acting on the brittle glass body. This design completely avoids localized stress concentration caused by direct contact between the screws and the glass, effectively dispersing the mechanical forces during installation. This ensures a stable connection between the screws and the door panel while completely avoiding the risk of cracks or breakage of the glass due to uneven stress.

[0010] Preferably, the double-glazed door panel includes an outer glass pane and an inner glass pane, both of which have several sets of axially corresponding mounting through holes on their surfaces.

[0011] Preferably, the fastener is cylindrical in shape, with the internally threaded cylinder axially passing through both ends of the cylindrical structure, and the outer side of the internally threaded cylinder engaging with the mounting through hole.

[0012] Preferably, a sealing ring is provided between the end face of the cylindrical structure in the fastener and both the outer and inner glass panes.

[0013] Based on the above technical solution, an elastic sealing ring of appropriate size (preferably made of low-temperature resistant and aging-resistant silicone rubber or EPDM rubber to suit the low-temperature working environment of refrigeration equipment) is arranged around the outer periphery of the fastener. The sealing ring needs to be assembled simultaneously during the double-layer glass lamination and fastener insertion stages. Through the sealing process, the sealing ring is made to fit tightly against the outer wall of the fastener and the inner wall of the glass to form a seamless sealing structure. The sealing ring fills the tiny gap between the fastener and the glass, effectively preventing external moisture and dust from seeping into the hollow layer through the assembly position, significantly improving the sealing performance of the door panel assembly position, and avoiding problems such as fogging of the hollow layer and moisture contamination of the inner wall of the glass.

[0014] Preferably, the length of the external thread of the glass screw is greater than the length of the internal threaded cylinder in the fastener.

[0015] Preferably, the thickness of the mounting hole on the outer glass is greater than the thickness of the screw-in portion in the glass screw.

[0016] Preferably, the outer end of the screwing part is provided with an inner corner groove.

[0017] Based on the above technical solutions, since the external threads of the glass screws perfectly match the internal threads of the fasteners, and the screws can be embedded entirely into the door panel structure, there is no outward protrusion of the screw head as in traditional screws, resulting in a flat, embedded installation effect. The embedded screw layout eliminates the obstruction and damage to the transparent appearance of the door panel by the mounting components, allowing the frameless glass door panel to maintain its overall visual integrity and simplicity, further enhancing the aesthetics of the frameless installation of the refrigeration equipment.

[0018] In summary, this application includes the following beneficial technical effects:

[0019] 1. This utility model achieves the pre-layout of the internal thread structure in the whole double-layer glass door panel by setting up a double-layer glass door panel and pre-embedding the fixing component in the hollow layer of the double-layer glass door panel, thereby realizing the non-destructive fixing of screws.

[0020] 2. This utility model has a simple structure. By setting glass screws with external threads and setting internal corner grooves at the ends of the glass screws, the embedded installation of glass screws is realized, thereby further improving the aesthetics of glass door panels after frameless installation.

[0021] 3. This utility model effectively improves the sealing performance at the assembly location by placing a sealing ring between the fixing component and the double-layer glass door panel. Attached Figure Description

The thickness of the mounting through hole 103 on the outer glass 101 is greater than the thickness of the screwing portion 202 in the glass screw 2. In this structure, the outer end of the screwing portion 202 is provided with an internal corner groove. The glass screw 2 is a screw made of glass material, such as high-strength glass or tempered glass.
