[0022] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] See Figures 1-8 The door guide rail connection structure of this disinfection cabinet includes a door body, a guide rail sleeve 1, and a shelf 2. The door body includes a door panel 3 and a door bracket 4. A connector 5 is provided on the door bracket 4. The guide rail sleeve 1 is located on the outside of the door bracket 4 and is connected to the connector 5. The shelf 2 is located on the rear side of the door bracket 4 and is connected to the connector 5. The door panel 3 is located on the front side of the door bracket 4 and is connected to the connector 5.

[0025] In this embodiment, the door bracket 4 serves as the basic support to provide an installation position for the adapter 5. The adapter 5 is used as a centralized connection hub, so that the guide rail sleeve 1, the shelf 2, and the door panel 3 can all be connected to the adapter 5. This avoids the need for each component to be directly assembled to the door bracket 4 using separate fixed fitting parts, effectively reducing the number of fixed fitting parts, simplifying the assembly steps, and improving the integration and stability of the overall structure.

[0026] Specifically, the door body includes a door panel 3 and a door bracket 4. The door bracket 4 serves as a basic support structure, providing an installation position for the adapter 5 and ensuring the stability of the connection. The adapter 5 is installed on the door bracket 4. As a core intermediary component, the adapter 5 enables the guide rail sleeve 1, the shelf 2, and the door panel 3 to be indirectly connected to the door bracket 4 through a unified interface, avoiding the redundant design of each component requiring separate fixing parts in the traditional method.

[0027] The adapter 5 is fixedly connected to the guide rail sleeve 1, the shelf 2, the door panel 3, and the door bracket 4 by fasteners, adhesive, or snap-fit.

[0028] Fastener connections ensure reliable connections through standardized screw and screw hole structures, suitable for parts requiring high-strength fixation; adhesive connections replace traditional mechanical parts with adhesives, simplifying structural design and reducing the number of parts; snap-fit ​​connections enable quick assembly and disassembly through elastic snap-fit ​​structures, significantly improving production efficiency. The selective application of these three methods allows the adapter to adapt to the stress characteristics and functional requirements of different components. For example, fasteners are prioritized in the load-bearing connection between the guide rail sleeve 1 and the door bracket 4, while adhesive is used in the non-load-bearing connection between the door panel 3 and the adapter 5, thus ensuring structural strength while also balancing ease of assembly. This multi-mode connection scheme directly addresses the assembly complexity caused by the numerous types of fasteners in existing technologies, achieving both a reduction in the number of parts and an optimization of assembly steps through modular design of the connection methods.

[0029] The adapter 5 is fixedly connected to the door bracket 4 and the guide rail sleeve 1. The adapter 5 is also fixedly connected to the door bracket 4 and the shelf 2.

[0030] The common fixed connection between the adapter 5, the door bracket 4, and the guide rail sleeve 1 achieves mechanical balance among the three through structural cooperation. This ensures the positioning accuracy of the guide rail sleeve 1 and the door bracket 4, while also enhancing the overall structure's vibration resistance. Simultaneously, the common fixed connection between the adapter 5, the door bracket 4, and the shelf 2 eliminates the assembly gaps that might occur with separate connections between the shelf 2 and the door bracket 4 in traditional solutions by sharing fixed points. This improves the overall rigidity of the door structure and the collaborative load-bearing capacity of its components. This dual common fixing mechanism effectively reduces the number of fixed fitting parts, simplifies the assembly process, and improves space utilization and mechanical transmission efficiency among components through structural integration.

[0031] The adapter 5 is provided with a door support sleeve fixing edge 5.1, the door bracket 4 is provided with a door bracket side edge 4.1, and the guide rail sleeve 1 is provided with a guide rail sleeve abutting edge 1.1. The door support sleeve fixing edge 5.1 and the guide rail sleeve abutting edge 1.1 abut against the inner and outer sides of the door bracket side edge 4.1 respectively, and are provided with corresponding door support sleeve fastening holes. The fasteners fasten on the door support sleeve fastening holes to achieve a fixed connection between the adapter 5, the door bracket 4, and the guide rail sleeve 1.

[0032] The door bracket sleeve fixing edge 5.1 of the adapter 5 and the guide rail sleeve 1's supporting edge respectively abut against the door bracket side edge 4.1 from both the inner and outer sides, and achieve three-point positioning and fixation through corresponding fastening holes. This design firstly eliminates the problem of assembly error accumulation caused by traditional multi-point independent fixing by using the door bracket side edge 4.1 as an intermediate support reference through the symmetrical layout of the door bracket sleeve fixing edge 5.1 and the guide rail sleeve supporting edge 1.1. Secondly, the inner and outer fitting method makes the force direction of the fastener perpendicular to the deformation direction of the structure, improving the shear resistance of the overall connection. Finally, by setting the fastening holes between the mating fixing edges and supporting edges, a single fastener can simultaneously penetrate three components, significantly reducing the number of fixing parts, simplifying the assembly process, and enhancing assembly consistency through the structure's self-positioning characteristics.

[0033] The adapter 5 is provided with a door support fixing edge 5.2, and the shelf 2 is provided with a shelf support edge 2.1. The door support fixing edge 5.2 and the shelf support edge 2.1 are respectively supported on the front and rear sides of the door support frame 4, and corresponding door support fastening holes are provided between them. The fasteners are fastened on the door support fastening holes to realize the adapter 5, the door support frame 4, and the shelf 2 are fixedly connected together.

[0034] By setting a door support fixing edge 5.2 on the adapter 5 and a support edge on the shelf 2, the two are respectively attached to the front and rear surfaces of the door support 4, forming a spatially complementary positioning structure. This front and rear side attachment design expands the connection surface between the adapter 5 and the shelf 2 from a single direction to a two-way constraint, avoiding the deflection risk caused by traditional single-sided fixing, and achieving unified control of the form and position tolerances of the three components through the door support 4 as an intermediate reference surface. The corresponding setting of the door support fastening holes transforms the connection that originally required two sets of independent fasteners into a single set of fasteners with shared hole positions. By the fastener penetrating the overlapping area of ​​the door support fixing edge 5.2 and the support edge of the shelf 2, the adapter 5, door support 4, and shelf 2 form a rigidly connected overall frame. This design not only eliminates the assembly steps required for the separate fixing of the shelf 2 in the original technology, but also achieves a synergistic enhancement effect on the connection strength of the three components through the principle of structural interference, ultimately realizing the modular integration of the connection structure while ensuring mechanical strength.

[0035] The adapter 5 is provided with a door panel fixing edge 5.3. The door panel 3 rests against the front side of the door panel fixing edge 5.3 and the door bracket side 4.1. The door panel 3 and the door panel fixing edge 5.3 are fixedly connected by adhesive.

[0036] The adapter 5 has a door panel fixing edge 5.3, which provides a dedicated fixing position for the door panel 3. This avoids the need to process additional mounting holes or use independent fasteners on the door panel 3 or adapter 5, thereby reducing the number of parts and processing complexity. The door panel 3 relies on the front side of the door panel fixing edge 5.3 and the side of the door bracket 4.1, and uses double-point support to achieve precise positioning, ensuring that the door panel 3 is stably attached before pasting, preventing displacement or misalignment during assembly, and improving positioning accuracy and assembly reliability. The door panel 3 is fixedly connected to the door panel fixing edge by pasting, replacing the traditional fastener method, eliminating the tightening operation step, which not only simplifies the assembly process, but also makes the door panel 3 and adapter 5 form a tighter whole, enhancing the stability and sealing of the structure, especially suitable for the use scenario of frequent opening and closing of the disinfection cabinet door.

[0037] In this embodiment, a fastener is also connected to the front side of the door bracket 4 to fix the connector 6, and the door panel 3 is also supported on the front side of the connector 6, and the two are fixedly connected by adhesive, which further improves the assembly stability between the door panel 3 and the door bracket 4.

[0038] The door support sleeve fixing edge 5.1 is turned outward on the outside of the door panel fixing edge 5.3, and the door support placement fixing edge 5.2 is turned outward on the end of the door support sleeve fixing edge 5.1. Alternatively, the door panel fixing edge 5.3 is turned outward on the inside with an inner flange 5.4, and the door support placement fixing edge 5.2 is turned outward on the end of the inner flange 5.4.

[0039] The design of the door support sleeve fixing edge 5.1 being flipped over to the outside of the door panel fixing edge 5.3 allows the door support sleeve fixing edge 5.1 to fully utilize the external space of the door panel 3 fixing edge for extension, avoiding interference with the fixing area of ​​the door panel 3. Simultaneously, the flipping over to the outside of the door panel 3 fixing edge ensures that the door support sleeve fixing edge 5.1 and the door panel 3 fixing edge form a cooperative support structure, reducing additional fixing requirements and enhancing the stability of the guide rail sleeve 1 connection. The configuration of the door support storage fixing edge 5.2 being flipped over at the end of the door support sleeve fixing edge 5.1 allows the door support storage fixing edge 5.2 to extend directly from the already positioned door support sleeve fixing edge 5.1. The flipping over to the end of the door support sleeve fixing edge 5.1 allows the installation reference of the guide rail sleeve 1 to be used as the starting point for connecting the storage rack 2, simplifying the assembly path of the storage rack 2, reducing alignment errors, and improving the overall rigidity of the door support frame 4 and the storage rack 2. Alternatively, an alternative is provided where the inner side of the door panel fixing edge 5.3 is turned up to have an inner turn-up edge 5.4. By adding an inner turn-up edge 5.4 structure to the inner side of the door panel 3 fixing edge, the door bracket fixing edge 5.2 is turned up according to the inner turn-up edge 5.4, providing an internal support point for the shelf 2, making the connection position closer to the center area of ​​the door body, facilitating the installation and operation of the shelf 2, while maintaining the flatness of the door panel 3 area, avoiding external interference, and further optimizing the space utilization and structural strength of the adapter 5.

[0040] The adapter 5 has an integrally formed door support sleeve fixing edge 5.1, door support placement fixing edge 5.2, door panel fixing edge 5.3, and inner flange 5.4.

[0041] The one-piece molded door support sleeve fixing edge 5.1, door support shelf fixing edge 5.2, door panel 3 fixing edge, and inward flange 5.4 make these components an inseparable whole during the manufacturing stage, eliminating the need for additional fasteners or assembly steps to connect the edges. This directly eliminates the misalignment, loosening, or insufficient strength problems that may occur in a split structure, thereby ensuring the precise fit and reliable support of the adapter 5 when connecting the guide rail sleeve 1, shelf 2, and door panel 3. The integrated design of the door bracket sleeve fixing edge 5.1 allows it to stably fit with the door bracket side edge 4.1 and the guide rail sleeve support edge 1.1, avoiding gaps or deformation caused by separate assembly. The integrated design of the door bracket placement fixing edge 5.2 ensures a tight fit with the support edge of the shelf 2, improving the stability of the shelf 2 installation. The integrated design of the door panel 3 fixing edge simplifies the pasting and fixing process with the door panel 3, reducing assembly errors. The integrated design of the inner flange 5.4 provides a continuous support base for the door bracket placement fixing edge 5.2, enhancing the torsional resistance and rigidity of the overall structure. This integrated design not only significantly reduces the number of parts and assembly time, but also significantly improves the overall strength and sealing performance of the door guide rail connection structure, effectively solving the problems of excessive fixing parts, cumbersome assembly, and low integration mentioned in the background art.

[0042] The door support sleeve fixing edge 5.1, the door support placement fixing edge 5.2, the door panel fixing edge 5.3, and the inward flange 5.4 are perpendicular to each other.

[0043] The fixed edge 5.1 of the door bracket sleeve, the side edge 4.1 of the door bracket, and the supporting edge 1.1 of the guide rail sleeve form a vertical positioning reference, ensuring the lateral stability of the guide rail sleeve 1 outside the door bracket 4. The fixed edge 5.2 of the door bracket and the supporting edge of the shelf 2 form a vertical clamping surface, and the front and rear positioning accuracy of the shelf 2 is achieved by using the side edge 4.1 of the door bracket as a vertical reference surface. The vertical cooperation between the fixed edge of the door panel 3 and the inner flange 5.4 provides a vertical support surface for the door panel 3 in the front and rear directions. At the same time, the vertical extension structure of the inner flange 5.4 enhances the overall bending stiffness of the adapter 5. This multi-directional vertical cooperation structure transforms the originally dispersed stress points into an interconnected three-dimensional support network, enabling each connecting component to form a stable mechanical balance system in three-dimensional space. This not only ensures the independent function of each component, but also eliminates the cumulative assembly error through the unification of the vertical reference surface, ultimately achieving a synergistic effect of improved structural strength and assembly accuracy.

[0044] The side 4.1 of the door bracket is flipped up on the outside of the door bracket 4, the side 1.1 of the guide rail sleeve is set at the front end of the guide rail sleeve 1, and the side 2.1 of the shelf is flipped up at the front end of the shelf 2.

[0045] The side 4.1 of the door bracket is flipped over on the outside of the door bracket 4, allowing it to form a coordinated inner and outer positioning with the guide rail sleeve's backing edge 1.1. This outer flipped edge structure enhances the mechanical strength of the door bracket 4 and provides guidance for the installation of the guide rail sleeve 1. The design of the guide rail sleeve's backing edge 1.1 being located at the front end of the guide rail sleeve 1 ensures that the contact surface between the guide rail sleeve 1 and the adapter 5 is located in the front area where stress is most concentrated. This front-end setting effectively disperses the stress from the guide rail sleeve 1, avoiding structural deformation caused by stress concentration. The design of the shelf 2's backing edge being flipped over at the front end of the shelf 2 ensures that the connection position between the shelf 2 and the door bracket 4 is precisely in the front area where its structure is most stable. This flipped edge structure not only improves the load-bearing capacity of the shelf 2 but also enhances the overall structure's vibration resistance through dual positioning on the front and rear sides. The specific settings of each side work together to achieve an efficient and reliable connection between the adapter 5, the door bracket 4, the guide rail sleeve 1, and the shelf 2.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
