Description

Technical Field

[0001] This utility model relates to the field of glass door technology, and in particular to a glass door structure. Background Technology

[0002] Glass door structures are widely used in construction, furniture, and home appliances, such as refrigerator doors, shower room partitions, and interior / exterior separation doors. These doors typically consist of a door frame and an internally inlaid glass panel. The frame not only supports and secures the glass but also directly affects the overall strength, sealing performance, and appearance quality of the door.

[0003] Currently, most glass door frames are made of a single material, such as all-metal profiles (e.g., aluminum alloy), all-plastic profiles, or all-wood structures. Metal profiles offer high strength but are also expensive and have poor thermal insulation; wooden frames are aesthetically pleasing but lack weather resistance and moisture resistance; plastic profiles (e.g., PVC) have good insulation and corrosion resistance, but their structural strength and dimensional stability are often limited by the extrusion process, making it difficult to achieve high-precision molding in complex connection areas. Moreover, if PVC profiles are used as door frames, the manufacturing process often involves mechanical connections at the four corners (e.g., corner brackets and screws) or welding, resulting in noticeable seams, poor sealing, and low assembly efficiency. Especially in scenarios with high requirements for insulated glass installation, the sealing and overall rigidity of the frame structure are crucial for thermal insulation performance.

[0004] In summary, existing glass door technologies suffer from problems such as obvious seams and low assembly efficiency. Utility Model Content

[0019] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0020] like Figures 1 to 4 As shown, this utility model provides a glass door structure, which includes a door frame 1 and a hollow glass 2 disposed inside the door frame 1. The door frame 1 is mainly composed of two parts, namely an extruded profile 3 and an injection molded part 4. Specifically, there are two extruded profiles 3 and two injection molded parts 4. These four parts are spliced ​​together to form a rectangular frame structure, thereby constituting the overall frame of the door frame 1.

[0021] Furthermore, each of the two injection-molded parts 4 has two protrusions 41 on its adjacent side surface, which are used to mate with the extruded profile 3. Correspondingly, the extruded profile 3 has a cavity 31 specifically designed to accommodate these protrusions 41, ensuring a tight fit between the components and the stability of the overall structure. This design not only improves the strength and sealing of the door frame 1, but also allows the insulated glass 2 to be securely embedded in the door frame 1, thereby enhancing the overall usability. More specifically, this design also enables a tight connection between the extruded profile and the injection-molded parts, eliminating the need for mechanical connections such as corner brackets or screws, or welding connections, thus avoiding the problem of noticeable seams.

[0022] This splicing method is simple to operate and can effectively improve assembly efficiency. Moreover, the rectangular frame structure of the door frame has good overall rigidity, providing stable support for the insulated glass, and can better ensure the sealing performance of the glass door in scenarios with high requirements for insulated glass installation.

[0023] like Figures 1 to 7 As shown, in some embodiments of this utility model, the insulated glass 2 and the door frame 1 are interference-fitted. This interference fit design creates a certain preload when the insulated glass 2 is installed into the door frame 1, further enhancing the stability of the connection between the insulated glass 2 and the door frame 1. Simultaneously, the interference fit effectively prevents external moisture, dust, and other impurities from entering the door, improving the sealing performance of the glass door. In practical applications, this fit also reduces loosening caused by vibration or temperature changes, extending the service life of the glass door.

[0024] like Figures 1 to 7 As shown, in some embodiments of this utility model, a sealing and fixing adhesive layer A is further provided between the insulated glass 2 and the door frame 1. This sealing and fixing adhesive layer A is formed by applying a layer of silicone sealant to a specific location on the door frame 1, i.e., the side directly in contact with the insulated glass 2. After appropriate curing, a tight and firm sealing and fixing adhesive layer A is finally formed. This adhesive layer not only ensures a tight bond between the insulated glass 2 and the door frame 1, but also provides a good seal, preventing the intrusion of external moisture and gas.

[0025] The adhesive layer, combined with the interference fit design between the insulated glass 2 and the door frame 1, ensures that there are no obvious gaps on the front of the glass door structure.

[0026] like Figures 1 to 7 As shown, in some embodiments of this utility model, two injection molded parts 4 are disposed on the horizontal side of the rectangular frame structure, and two extruded profiles 3 are disposed on the vertical side of the rectangular frame structure; that is, in the actual installation process, the two extruded profiles 3 are disposed opposite each other, the two injection molded parts 4 are respectively disposed at both ends of the extruded profiles 3, and the two protrusions 41 on each injection molded part 4 are used to cooperate with the two extruded profiles 3, so that the two extruded profiles 3 and the two injection molded parts 4 are spliced ​​together to form a rectangular frame structure; Specifically, the two extruded profiles 3 are positioned along the vertical edges of the rectangular frame structure to enhance the overall stability and support. This layout not only optimizes the synergy of the components but also improves the mechanical properties and service life of the entire rectangular frame structure. The injection molded part 4 is placed on the horizontal side of the rectangular frame structure, which serves as a side limit.

[0027] like Figures 1 to 7 As shown, in some embodiments of this utility model, the injection molded part 4 includes an injection molded housing 5, an upper injection molded part A 6 and a lower injection molded part B 7, and the injection molded housing 5 is provided with a mounting groove 51 for accommodating the lower injection molded part B 7; The bottom injection molded part B 7 has a groove 71 at one end near the mounting groove 51, and the upper injection molded part A 6 has a protrusion 61 integrally formed to cooperate with the groove 71; This design is intended to control the gap at the mating point of the upper and lower injection molded parts. Specifically, a groove 71 is provided on the lower injection molded part B7, and a protrusion 61 is provided on the upper injection molded part A6. During installation, the protrusion 61 can be placed in the groove 71 to achieve the installation and positioning of the lower injection molded part B7 and the upper injection molded part A6, which can effectively prevent poor appearance gaps at this point during mass production. Meanwhile, the presence of the injection-molded housing 5 provides a stable installation environment for the upper injection-molded part A 6 and the lower injection-molded part B 7. The mounting groove 51 on it can accurately accommodate the lower injection-molded part B 7, ensuring the structural compactness and stability of the entire injection-molded part 4. This design not only improves the overall aesthetics of the glass door structure, but also greatly enhances its reliability and durability, providing a strong guarantee for the long-term stable operation of the glass door.

[0028] like Figures 1 to 7 As shown, in some embodiments of this utility model, the front end of the injection-molded shell 5 is integrally formed with a side blocking strip 52; the side blocking strip 52 is used to limit the upper and lower ends of the insulating glass 2, and the insulating glass 2 can be fixed by the sealing and fixing adhesive layer A. Specifically, the front end of the injection-molded housing 5 is manufactured using a one-piece molding process and features an edge blocking strip 52. The main function of this edge blocking strip 52 is to precisely limit the upper and lower ends of the insulating glass unit 2, ensuring its stable position during installation and use. Furthermore, the edge blocking strip 52 also securely fixes the insulating glass unit 2 to the sealing adhesive layer A, effectively preventing displacement or loosening of the insulating glass unit 2 within the housing, further enhancing the overall sealing and stability of the structure.

[0029] like Figures 1 to 7 As shown, in some embodiments of this utility model, a locking strip 32 is integrally formed on the outer edge of the front side of the extruded profile 3; the locking strip 32 extends into the inside of the extruded profile 3, so that when the insulating glass 2 is assembled into the door frame 1, the left and right ends of the insulating glass 2 are respectively locked between the locking strips 32 on the two extruded profiles 3; similarly, the left and right ends of the insulating glass 2 can also be further fixed between the two locking strips 32 by the sealing and fixing adhesive layer A; Specifically, the outer edge of the front side of the extruded profile 3 is equipped with a locking strip 32 using an integrated molding technology. This design makes the locking strip 32 and the extruded profile 3 a single unit, enhancing the structural stability. The locking strip 32 extends inward to the extruded profile 3, forming a specific space. When the insulated glass 2 is assembled into the door frame 1, the left and right ends of the insulated glass 2 can be locked by the locking strips 32 on the two extruded profiles 3 respectively. This design not only ensures the accurate position of the insulated glass 2 during assembly but also effectively prevents the insulated glass 2 from swaying left and right during use through the fixing effect of the locking strips 32. In addition, to further enhance the fixing effect of the insulated glass 2, the left and right ends of the insulated glass 2 can be firmly fixed between the two locking strips 32 using a sealing and fixing adhesive layer A, thereby greatly improving the overall sealing and stability of the glass door structure.

[0030] like Figures 1 to 7 As shown, in some embodiments of this utility model, the inner side of the extruded profile 3 is integrally formed with a support member 33 for supporting the insulating glass 2.

[0031] The support member 33 is arranged along the length of the extruded profile 3, and its front side can fit against the rear side of the insulating glass 2, providing stable and reliable support for the insulating glass 2. This one-piece molded support member 33 is closely connected to the extruded profile 3, further enhancing the strength of the overall structure and preventing the insulating glass 2 from sinking or deforming due to its own weight or external forces, thus ensuring the flatness and stability of the glass door during long-term use.

[0032] like Figures 1 to 7 As shown, in some embodiments of this utility model, a bearing strip 62 is integrally formed on one end of the upper injection molded part A6 away from the protrusion 61; The supporting edge strip 62 is used to support the rear side of the insulated glass 2; Specifically, during the manufacturing process of the upper injection molded part A6, a load-bearing edge strip 62 is integrally formed at the end furthest from the protrusion 61. This strip stably supports the rear side of the insulated glass 2, providing a reliable support point. As a result, the insulated glass 2 is more stable within the glass door structure, less prone to wobbling or displacement, thus further enhancing the stability and reliability of the entire glass door structure.

[0033] like Figures 1 to 7 As shown, in some embodiments of this utility model, the protrusion 41 is in the shape of a cuboid. The cuboid design of the protrusion 41 not only increases the structural stability but also makes its contact with the extruded profile 3 more compact and stable. This shape design helps to disperse stress and reduce deformation caused by external forces, thereby further improving the overall strength and durability of the glass door structure.

[0034] like Figures 1 to 7 As shown, in some embodiments of this utility model, the protrusion 41 is integrally formed on the injection-molded housing 5; This one-piece molding method ensures a seamless connection between the protrusion 41 and the injection-molded shell 5, avoiding gaps or weaknesses that may arise due to loose connections. This design not only enhances the overall aesthetics of the glass door structure but also further strengthens its structural strength and stability, enabling the glass door to maintain better performance and appearance during long-term use.

[0035] like Figures 1 to 7 As shown, in some embodiments of this utility model, the protrusion 41 is fixed to the injection-molded housing 5 by screws; Using screws to secure the protrusion 41 to the injection-molded housing 5 provides another reliable solution. This method of fixing offers the advantages of simple installation and easy disassembly, facilitating maintenance or component replacement of the glass door structure when needed. Simultaneously, screw fixing ensures a stable relative position between the protrusion 41 and the injection-molded housing 5, preventing abnormal noises or performance degradation caused by loosening, thus guaranteeing the long-term stability and reliability of the glass door structure.

[0036] like Figures 1 to 7 As shown, in some embodiments of this utility model, a sealing and fixing adhesive layer C is provided between the protrusion 41 and the cavity 31; the sealing and fixing adhesive layer C is formed by dripping quick-drying adhesive into the gap between the protrusion 41 and the cavity 31. The sealing adhesive layer C not only effectively fills the tiny gaps between the protrusion 41 and the cavity 31, preventing the intrusion of external impurities such as dust and moisture, but also enhances the tightness of the connection between the two, further improving the overall stability of the glass door structure. The choice of quick-drying adhesive makes the sealing process rapid and efficient, greatly shortening the production cycle, while ensuring the durability and reliability of the sealing effect.

[0037] like Figures 1 to 7 As shown, in some embodiments of this utility model, a sealing and fixing adhesive layer B is provided between the protrusion 61 and the groove 71; The sealing and fixing layer B is formed by injecting quick-drying adhesive or sealant into the gap between the protrusion 61 and the groove 71 and then curing it. This sealing and fixing layer B not only fully fills the tiny gap between the protrusion 61 and the groove 71, preventing external moisture and debris from entering, but also strengthens the connection between the protrusion 61 and the groove 71, making the glass door structure more stable and reliable during use. The selection of a suitable specialized sealant ensures that the sealing and fixing layer B has good adhesion and durability, effectively improving the quality and service life of the glass door structure.

[0038] This utility model provides a glass door structure, comprising a door frame and insulated glass units housed within the door frame. The door frame is composed of extruded profiles and injection-molded parts; two extruded profiles and two injection-molded parts are spliced ​​together to form a rectangular frame structure. Specifically, by inserting the protrusions on the injection-molded parts into the cavities inside the extruded profiles, a tight connection between the extruded profiles and injection-molded parts can be achieved, eliminating the need for mechanical connections such as corner brackets or screws, or welding connections, thus avoiding noticeable seams. Simultaneously, this splicing method is simple to operate and effectively improves assembly efficiency. Moreover, the rectangular frame structure of the door frame has good overall rigidity, providing stable support for the insulated glass, and better ensuring the thermal insulation performance of the glass door in scenarios with high requirements for insulated glass installation. In summary, the entire glass door is easy and efficient to install, and its reasonable structural design meets high aesthetic requirements.
