Description

Technical Field

[0001] This application relates to the field of disinfection cabinet technology, and in particular to a disinfection cabinet slide rail structure and a disinfection cabinet. Background Technology

[0002] As a common kitchen appliance, the main function of a disinfection cabinet is to sterilize tableware after washing, thereby improving food hygiene. With the improvement of people's living standards, the requirements for the functionality and aesthetics of household appliances are also increasing. Especially for frequently used devices, the ease of operation and appearance design of a disinfection cabinet directly affect the user experience. Among these, the sliding rail structure is a key component for the opening and closing of the disinfection cabinet door; while ensuring smooth operation, it is also necessary to consider both safety and aesthetics.

[0003] Traditional sliding rails used in the market consist of a base plate fixed inside the disinfection cabinet, which is then connected to the door panel via a rail sleeve for overall assembly. Screws are used to tightly connect the various rail components to ensure structural stability. However, the manufacturing process of the rail sleeve produces sharp burrs on the top and bottom edges, and the side fixing screws are exposed. This not only detracts from the overall aesthetics of the product but also increases the difficulty of cleaning, easily scratches the user's fingers, and affects the user experience. Utility Model Content

[0004] To address the shortcomings of sharp burrs on the upper and lower edges of the slide rail cover and exposed fixing screws, which can easily scratch users' fingers and affect the user experience, this application provides a slide rail structure for a disinfection cabinet and a disinfection cabinet.

[0005] This application provides a slide rail structure for a disinfection cabinet and a disinfection cabinet employing the following technical solution:

[0006] A disinfection cabinet slide rail structure and disinfection cabinet, including a cabinet body and a door panel, further including a support plate connected to the rear side of the cabinet body, a support frame connected to the open end of the cabinet body, a guide rail bracket disposed on one side of the cabinet body and fixedly connected at both ends to the support plate and the support frame respectively, a first slide rail assembly fixedly connected to the guide rail bracket, a second slide rail assembly sleeved on the outside of the first slide rail assembly and slidably connected to the first slide rail assembly, and a third slide rail assembly sleeved on the outside of the second slide rail assembly and slidably connected to the second slide rail assembly, wherein the end of the third slide rail assembly away from the support plate is connected to the door panel; both the second slide rail assembly and the third slide rail assembly are provided with anti-scratch side edges bent in the direction facing the cabinet body.

[0007] By adopting the above technical solution, when the user pulls the door panel, the door panel drives the third slide rail assembly to slide outward from the second slide rail assembly. At the same time, the second slide rail assembly slides outward from the first slide rail assembly fixed to the guide rail bracket, forming a three-stage telescopic movement. The anti-scratch side edge, through a structural design that bends towards the cabinet, covers the side of the slide rail during the sliding of the second and third slide rail assemblies, avoiding the burrs and protruding screws problems of traditional slide rail sleeves. This application achieves the overall stability of the slide rail structure through the fixed connection between the guide rail bracket and the support plate and support frame. Eliminating the slide rail sleeve eliminates the hidden danger of edge burrs, simplifies the processing steps, and improves assembly efficiency. The three-stage nested sliding structure of the first, second, and third slide rail assemblies ensures smooth door panel pushing and pulling. The bending design of the anti-scratch side edge not only prevents users from being scratched when cleaning, but also improves user experience and safety.

[0008] Preferably, the first slide rail assembly includes a first slide rail body fixedly connected to the guide rail bracket, and a first guide rail side edge connected to the side edge of the first slide rail body and bent in a direction away from the cabinet, wherein a first outer slide rail groove is provided on the first guide rail side edge.

[0009] The second slide rail assembly includes a second slide rail body arranged parallel to the first slide rail body, and a second guide rail side edge connected to the side edge of the second slide rail body and bent in the direction close to the cabinet. The second guide rail side edge is provided with a second inner slide rail groove corresponding to the first outer slide rail groove.

[0010] The first slide rail assembly also includes first balls respectively inserted into the first outer slide rail groove and the second inner slide rail groove.

[0011] By adopting the above technical solution, the side edges of the first guide rail and the side edges of the second guide rail form a complementary nested structure. The rolling cooperation of the first ball in the first outer slide rail groove and the second inner slide rail groove achieves low-friction sliding between the first slide rail assembly and the second slide rail assembly, reducing wear and extending service life. The parallel arrangement of the first slide rail body and the second slide rail body ensures that the sliding trajectory of the second slide rail assembly is accurate and stable. Combined with the rolling guidance mechanism of the first ball and the first outer slide rail groove and the second inner slide rail groove, the processing steps are simplified after the slide rail sleeve is eliminated, while enhancing the overall rigidity of the slide rail structure and assembly efficiency.

[0012] Preferably, the third slide rail assembly includes a third slide rail body arranged parallel to the second slide rail body, and a third guide rail side edge connected to the side edge of the third slide rail body and bent in the direction close to the cabinet, wherein a third inner slide rail groove is provided on the third guide rail side edge.

[0013] The second guide rail side edge is also provided with a second outer slide rail groove corresponding to the third inner slide rail groove, and the third slide rail assembly also includes second balls respectively inserted into the second outer slide rail groove and the third inner slide rail groove.

[0014] By adopting the above technical solution, the side edge of the third guide rail and the side edge of the second guide rail form a nested fit. The second ball bearings inserted in the second outer slide rail groove and the third inner slide rail groove achieve low-friction and smooth sliding of the third slide rail assembly relative to the second slide rail assembly. The rolling fit of the second ball bearings in the second outer slide rail groove and the third inner slide rail groove further reduces the contact wear between the second slide rail assembly and the third slide rail assembly, and extends the service life.

[0015] The parallel arrangement of the third slide rail body and the second slide rail body ensures the precise nested telescopic movement trajectory of the third slide rail assembly and the second slide rail assembly. Combined with the linkage rolling of the first ball and the second ball, it improves the smoothness of pushing and pulling and the structural stability.

[0016] Preferably, the anti-scratch side edge includes an arc-shaped side edge connected to the second guide rail side edge, and a vertical side edge connected to the third guide rail side edge and arranged parallel to the third slide rail body.

[0017] By adopting the above technical solution, the scratch-resistant side edge is connected to the second guide rail side edge through an arc-shaped side edge to form a smooth transition curved surface. When the second slide rail assembly slides, it guides and covers the side gap between the second slide rail assembly and the first slide rail assembly, and the arc-shaped structure eliminates the risk of burrs cutting hands. The vertical side edge is set parallel to the third slide rail body and connected to the third guide rail side edge. When the third slide rail assembly slides, it is close to the side of the second slide rail assembly through the vertical extension surface, forming a double-layer sealing protection, further preventing burrs from being exposed on the side edge of the third slide rail body. The composite design of the scratch-resistant side edge achieves side protection of the slide rail after eliminating the slide rail sleeve, improving assembly efficiency and user cleaning safety.

[0018] Preferably, the second guide rail side edges are provided on both the upper and lower sides of the second slide rail body, and the two second guide rail side edges and the second slide rail body surround to form an inner slide rail cavity, and the first slide rail assembly is movably inserted into the inner slide rail cavity;

[0019] The third slide rail body has third guide rail side edges on both the upper and lower sides. The two third guide rail side edges and the third slide rail body surround each other to form an outer slide rail cavity. The second slide rail assembly is movably inserted into the outer slide rail cavity.

[0020] By adopting the above technical solution, the inner slide rail cavity is used for the insertion of the first slide rail assembly, so that the second slide rail assembly can slide smoothly relative to the first slide rail assembly. The outer slide rail cavity is used to wrap the second slide rail assembly inside, forming a layer-by-layer nested telescopic structure of the first slide rail assembly, the second slide rail assembly, and the third slide rail assembly. The inner slide rail cavity wraps the first slide rail assembly through the bending design of the side edge of the second guide rail, and the outer slide rail cavity wraps the second slide rail assembly through the bending design of the side edge of the third guide rail, eliminating the risk of exposed burrs and protruding screws.

[0021] Preferably, the third slide rail assembly further includes a connecting bracket connected to the end of the third slide rail body and connected to the door panel; the connecting bracket includes a door panel connecting side plate that is flush against and connected to the door panel, and a slide rail connecting side plate that is connected to the door panel connecting side plate and flush against the third slide rail body, the slide rail connecting side plate being provided with an anti-detachment through hole, and the third slide rail body being provided with an anti-detachment protrusion for insertion into the anti-detachment through hole.

[0022] By adopting the above technical solution, the third slide rail assembly forms a double support structure through the door panel connecting side plate of the connecting bracket being tightly fixed to the door panel, and the slide rail connecting side plate being tightly connected to the third slide rail body, thereby enhancing the connection stability between the door panel and the third slide rail assembly. The anti-detachment protrusion is inserted into the anti-detachment through hole of the slide rail connecting side plate to form a mechanical locking structure, preventing the door panel from falling off due to force displacement or vibration during the sliding process of the third slide rail assembly, thus improving the safety of use. The fitting design of the slide rail connecting side plate and the third slide rail body disperses the stress concentration when the door panel is pushed and pulled through surface contact, reducing the risk of deformation of the third slide rail body and extending the structural life.

[0023] Preferably, both the first ball bearing and the second ball bearing are arranged in an array along the length of the second slide rail assembly.

[0024] By adopting the above technical solution, the first ball bearing and the second ball bearing are arranged in an array along the length of the second slide rail assembly, so that the contact surfaces of each section of the slide rail assembly, the second slide rail assembly and the third slide rail assembly are evenly stressed during the sliding process. Multi-point rolling support reduces local friction and wear, extends the service life of the first ball bearing and the second ball bearing, as well as the first outer slide rail groove, the second inner slide rail groove, the second outer slide rail groove and the third inner slide rail groove, and improves the linear smoothness of the door panel pushing and pulling action.

[0025] Preferably, the guide rail bracket includes a guide rail bracket body, a first connecting side edge disposed at one end of the guide rail bracket body and fixedly connected to the support plate, and a second connecting side edge disposed at the other end of the guide rail bracket body and fixedly connected to the support frame.

[0026] By adopting the above technical solution, the guide rail bracket body is fixedly connected to the support plate through the first connecting side edge and fixedly connected to the support frame through the second connecting side edge to form a support frame, which ensures the installation reference surface accuracy and sliding trajectory stability of the first slide rail assembly, the second slide rail assembly and the third slide rail assembly; the guide rail bracket body, the first connecting side edge and the second connecting side edge are integrally formed, which enhances the overall rigidity of the guide rail bracket and extends the overall structural life of the disinfection cabinet.

[0027] Preferably, the support frame is provided with a pull-out through hole, and the second slide rail assembly and the third slide rail assembly are both inserted into the pull-out through hole.

[0028] By adopting the above technical solution, the support frame provides a through sliding channel for the second and third slide rail assemblies by setting pull-out through holes. The inner wall of the through holes guides and limits the sliding trajectory of the second and third slide rail assemblies, preventing lateral displacement of the second and third slide rail assemblies during the pushing and pulling process, and enhancing the linear stability of the door panel's pushing and pulling action.

[0029] A disinfection cabinet, including the aforementioned disinfection cabinet slide rail structure.

[0030] By adopting the above technical solutions, the disinfection cabinet includes a disinfection cabinet slide rail structure, which improves the stability of the linear sliding trajectory; the elimination of slide rail sleeves and exposed screws eliminates the risk of burrs cutting hands; and the smoothness of door panel sliding, structural durability, appearance flatness, and cleaning safety are improved.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. When the user pulls the door panel, the door panel drives the third slide rail assembly to slide outward from the second slide rail assembly. At the same time, the second slide rail assembly slides outward from the first slide rail assembly fixed to the guide rail bracket, forming a three-stage telescopic movement. The anti-scratch side edge, through a structural design that bends towards the cabinet, covers the side of the slide rail during the sliding of the second and third slide rail assemblies, avoiding the burrs and protruding screws problems of traditional slide rail sleeves. This application achieves the overall stability of the slide rail structure through the fixed connection between the guide rail bracket and the support plate and support frame. Eliminating the slide rail sleeve eliminates the hidden danger of edge burrs, simplifies the processing steps, and improves assembly efficiency. The three-stage nested sliding structure of the first, second, and third slide rail assemblies ensures smooth door panel pushing and pulling. The bending design of the anti-scratch side edge not only prevents users from being scratched when cleaning, but also improves user experience and safety.

[0033] 2. The scratch-resistant side edge connects smoothly with the side edge of the second guide rail through an arc-shaped connection, forming a curved surface. When the second slide rail assembly slides, it guides and covers the side gap between the second and first slide rail assemblies, eliminating the risk of burrs cutting hands. The vertical side edge is set parallel to the third slide rail body and connects with the side edge of the third guide rail. When the third slide rail assembly slides, it extends vertically to the side of the second slide rail assembly, forming a double-layer seal and further preventing burrs from being exposed on the side edge of the third slide rail body. The composite design of the scratch-resistant side edge achieves side protection of the slide rail after the slide rail sleeve is removed, improving assembly efficiency and user cleaning safety.

[0042] The following is in conjunction with the appendix Figures 1 to 4 This application will be described in further detail.

[0043] This application discloses a slide rail structure for a disinfection cabinet and a disinfection cabinet. (Refer to...) Figure 1 A disinfection cabinet slide rail structure includes a cabinet body 1 and a door panel 2, a support plate 3 connected to the rear side of the cabinet body 1, a support frame 4 connected to the open end of the cabinet body 1, a guide rail bracket 5 located on one side of the cabinet body 1 and fixedly connected at both ends to the support plate 3 and the support frame 4 respectively, a first slide rail assembly 6 fixedly connected to the guide rail bracket 5, a second slide rail assembly 7 sleeved on the outside of the first slide rail assembly 6 and slidably connected to the first slide rail assembly 6, and a third slide rail assembly 8 sleeved on the outside of the second slide rail assembly 7 and slidably connected to the second slide rail assembly 7. The end of the third slide rail assembly 8 away from the support plate 3 is connected to the door panel 2. Both the second slide rail assembly 7 and the third slide rail assembly 8 are provided with anti-scratch side edges 9 bent in the direction facing the cabinet body 1.

[0044] When the user pulls the door panel 2, the door panel 2 drives the third slide rail assembly 8 to slide outward from the second slide rail assembly 7. At the same time, the second slide rail assembly 7 slides outward from the first slide rail assembly 6 fixed to the guide rail bracket 5, forming a three-stage telescopic movement. The anti-scratch side edge 9, through its structural design of bending towards the cabinet 1, covers the side of the slide rail during the sliding of the second slide rail assembly 7 and the third slide rail assembly 8, avoiding the burrs and protruding screws problems of traditional slide rail sleeves. This application achieves the overall stability of the slide rail structure through the fixed connection between the guide rail bracket 5 and the support plate 3 and the support frame 4. Eliminating the slide rail sleeve eliminates the hidden danger of edge burrs, simplifies the processing steps, and improves assembly efficiency. The three-stage nested sliding structure of the first slide rail assembly 6, the second slide rail assembly 7, and the third slide rail assembly 8 ensures smooth pushing and pulling of the door panel 2. The bending design of the anti-scratch side edge 9 not only prevents users from being scratched when cleaning, but also improves user experience and safety.

[0045] Furthermore, such as Figure 2 and Figure 3 As shown, the first slide rail assembly 6 includes a first slide rail body 61 fixedly connected to the guide rail bracket 5, and a first guide rail side edge 62 connected to the side edge of the first slide rail body 61 and bent in a direction away from the cabinet 1. A first outer slide rail groove 63 is provided on the first guide rail side edge 62.

[0046] The second slide rail assembly 7 includes a second slide rail body 71 arranged parallel to the first slide rail body 61, and a second guide rail side edge 72 connected to the side edge of the second slide rail body 71 and bent in the direction close to the cabinet 1. The second guide rail side edge 72 is provided with a second inner slide rail groove 73 corresponding to the first outer slide rail groove 63.

[0047] The first slide rail assembly 6 also includes first ball bearings 64 respectively inserted into the first outer slide rail groove 63 and the second inner slide rail groove 73.

[0048] The first guide rail side edge 62 and the second guide rail side edge 72 of this application form a complementary nested structure. The first ball bearing 64 rolls in the first outer slide rail groove 63 and the second inner slide rail groove 73 to achieve low-friction sliding between the first slide rail assembly 6 and the second slide rail assembly 7, thereby reducing wear and extending service life. The parallel arrangement of the first slide rail body 61 and the second slide rail body 71 ensures that the sliding trajectory of the second slide rail assembly 7 is accurate and stable. Combined with the rolling guidance mechanism of the first ball bearing 64, the first outer slide rail groove 63 and the second inner slide rail groove 73, the processing steps are simplified after the slide rail sleeve is eliminated, while the overall rigidity of the slide rail structure and the assembly efficiency are enhanced.

[0049] Furthermore, such as Figure 2 and Figure 3 As shown, the third slide rail assembly 8 includes a third slide rail body 81 arranged parallel to the second slide rail body 71, and a third guide rail side edge 82 connected to the side edge of the third slide rail body 81 and bent in the direction close to the cabinet 1. A third inner slide rail groove 83 is provided on the third guide rail side edge 82.

[0050] The second guide rail side edge 72 is also provided with a second outer slide rail groove 74 corresponding to the third inner slide rail groove 83. The third slide rail assembly 8 also includes second balls 84 respectively inserted into the second outer slide rail groove 74 and the third inner slide rail groove 83.

[0051] The third guide rail side edge 82 and the second guide rail side edge 72 form a nested fit. The second ball bearing 84 inserted in the second outer slide rail groove 74 and the third inner slide rail groove 83 achieves low-friction and smooth sliding of the third slide rail assembly 8 relative to the second slide rail assembly 7. The rolling fit of the second ball bearing 84 in the second outer slide rail groove 74 and the third inner slide rail groove 83 further reduces the contact wear between the second slide rail assembly 7 and the third slide rail assembly 8, and extends the service life.

[0052] The parallel arrangement of the third slide rail body 81 and the second slide rail body 71 ensures the precise nested telescopic movement trajectory of the third slide rail assembly 8 and the second slide rail assembly 7. Combined with the linkage rolling of the first ball 64 and the second ball 84, the smoothness of pushing and pulling and the structural stability are improved.

[0053] Specifically, such as Figure 3 As shown, the anti-scratch side edge 9 includes an arc-shaped side edge 91 connected to the second guide rail side edge 72, and a vertical side edge 92 connected to the third guide rail side edge 82 and arranged parallel to the third slide rail body 81.

[0054] The anti-scratch side edge 9 of this application forms a smooth transition curved surface by connecting the arc-shaped side edge 91 with the second guide rail side edge 72. When the second slide rail assembly 7 slides, it guides and covers the side gap between the second slide rail assembly 7 and the first slide rail assembly 6, and the arc-shaped structure eliminates the risk of burrs cutting hands. The vertical side edge 92 is set parallel to the third slide rail body 81 and connected to the third guide rail side edge 82. When the third slide rail assembly 8 slides, it is close to the side of the second slide rail assembly 7 through the vertical extension surface, forming a double-layer sealing protection, further preventing the burrs on the side edge of the third slide rail body 81 from being exposed. The composite design of the anti-scratch side edge 9 achieves side protection of the slide rail after the slide rail sleeve is eliminated, which improves the assembly efficiency and user cleaning safety.

[0055] More specifically, such as Figure 3 As shown, the second slide rail body 71 has second guide rail side edges 72 on both the upper and lower sides. The two second guide rail side edges 72 and the second slide rail body 71 surround each other to form an inner slide rail cavity 75. The first slide rail assembly 6 is movably inserted into the inner slide rail cavity 75.

[0056] The third slide rail body 81 has third guide rail side edges 82 on both the upper and lower sides. The two third guide rail side edges 82 and the third slide rail body 81 surround each other to form an outer slide rail cavity 85. The second slide rail assembly 7 is movably inserted into the outer slide rail cavity 85.

[0057] The inner slide rail cavity 75 is used for the insertion of the first slide rail assembly 6 so that the second slide rail assembly 7 can slide smoothly relative to the first slide rail assembly 6. The outer slide rail cavity 85 is used to enclose the second slide rail assembly 7 inside, forming a layer-by-layer nested telescopic structure of the first slide rail assembly 6, the second slide rail assembly 7 and the third slide rail assembly 8. The inner slide rail cavity 75 encloses the first slide rail assembly 6 through the bending design of the second guide rail side edge 72, and the outer slide rail cavity 85 encloses the second slide rail assembly 7 through the bending design of the third guide rail side edge 82, eliminating the risk of exposed burrs and protruding screws.

[0058] In addition, such as Figure 4 As shown, the third slide rail assembly 8 also includes a connecting bracket 86 connected to the end of the third slide rail body 81 and connected to the door panel 2; the connecting bracket 86 includes a door panel connecting side plate 861 that is close to and connected to the door panel 2, and a slide rail connecting side plate 862 that is connected to the door panel connecting side plate 861 and close to the third slide rail body 81. The slide rail connecting side plate 862 is provided with an anti-detachment through hole 863, and the third slide rail body 81 is provided with an anti-detachment protrusion 811 for insertion into the anti-detachment through hole 863.

[0059] The third slide rail assembly 8 of this application forms a double support structure by tightly fixing the door panel 2 to the door panel 2 via the door panel connecting side plate 861 of the connecting bracket 86 and the slide rail connecting side plate 862 to the third slide rail body 81, thereby enhancing the connection stability between the door panel 2 and the third slide rail assembly 8. The anti-detachment protrusion 811 is inserted into the anti-detachment through hole 863 of the slide rail connecting side plate 862 to form a mechanical locking structure, which prevents the door panel 2 from falling off due to force displacement or vibration during the sliding process of the third slide rail assembly 8, thereby improving the safety of use. The fitting design of the slide rail connecting side plate 862 and the third slide rail body 81 disperses the stress concentration when the door panel 2 is pushed and pulled through surface contact, reduces the risk of deformation of the third slide rail body 81, and extends the structural life.

[0060] And, as Figure 2 As shown, the first ball bearing 64 and the second ball bearing 84 are arranged in an array along the length of the second slide rail assembly 7.

[0061] In this application, the first ball bearing 64 and the second ball bearing 84 are arranged in an array along the length of the second slide rail assembly 7, so that the contact surfaces of each slide rail section of the first slide rail assembly 6, the second slide rail assembly 7 and the third slide rail assembly 8 are evenly stressed during the sliding process. The multi-point rolling support reduces local friction and wear, extends the service life of the first ball bearing 64 and the second ball bearing 84, as well as the first outer slide rail groove 63, the second inner slide rail groove 73, the second outer slide rail groove 74 and the third inner slide rail groove 83, and improves the linear smoothness of the door panel 2's push and pull action.

[0062] Furthermore, such as Figure 4 As shown, the guide rail bracket 5 includes a guide rail bracket body 51, a first connecting side edge 52 located at one end of the guide rail bracket body 51 and fixedly connected to the support plate 3, and a second connecting side edge 53 located at the other end of the guide rail bracket body 51 and fixedly connected to the support frame 4.

[0063] The guide rail bracket body 51 of this application is fixedly connected to the support plate 3 via the first connecting side edge 52 and the second connecting side edge 53 is fixedly connected to the support frame 4 to form a support frame, ensuring the installation reference surface accuracy and sliding trajectory stability of the first slide rail assembly 6, the second slide rail assembly 7 and the third slide rail assembly 8; the guide rail bracket body 51, the first connecting side edge 52 and the second connecting side edge 53 are integrally formed, which enhances the overall rigidity of the guide rail bracket 5 and extends the overall structural life of the disinfection cabinet.

[0064] Furthermore, such as Figure 4 As shown, the support frame 4 is provided with a pull-out through hole 41, and the second slide rail assembly 7 and the third slide rail assembly 8 are both inserted into the pull-out through hole 41.

[0065] The support frame 4 of this application provides a through sliding channel for the second slide rail assembly 7 and the third slide rail assembly 8 by setting a pull-out through hole 41. The inner wall of the pull-out through hole 41 guides and limits the sliding trajectory of the second slide rail assembly 7 and the third slide rail assembly 8, so as to avoid the second slide rail assembly 7 and the third slide rail assembly 8 from lateral displacement during the push-pull process, thereby enhancing the linear stability of the push-pull action of the door panel 2.

[0066] Specifically, such as Figure 2 As shown, this application also discloses a disinfection cabinet, including a disinfection cabinet slide rail structure.

[0067] This application for a disinfection cabinet includes a slide rail structure that improves the stability of the linear sliding trajectory; the elimination of the slide rail cover and exposed screws eliminates the risk of burrs cutting hands; and the smoothness of the door panel 2 in pushing and pulling, structural durability, appearance flatness, and cleaning safety are improved.

[0068] The embodiment of this application describes a slide rail structure for a disinfection cabinet and the implementation principle of the disinfection cabinet as follows:

[0069] When the user pulls the door panel 2, the door panel 2 drives the third slide rail assembly 8 to slide outward from the second slide rail assembly 7. At the same time, the second slide rail assembly 7 slides outward from the first slide rail assembly 6 fixed to the guide rail bracket 5, forming a three-stage telescopic movement. The anti-scratch side edge 9, through its structural design of bending towards the cabinet 1, covers the side of the slide rail during the sliding of the second slide rail assembly 7 and the third slide rail assembly 8, avoiding the burrs and protruding screws problems of traditional slide rail sleeves. This application achieves the overall stability of the slide rail structure through the fixed connection between the guide rail bracket 5 and the support plate 3 and the support frame 4. Eliminating the slide rail sleeve eliminates the hidden danger of edge burrs, simplifies the processing steps, and improves assembly efficiency. The three-stage nested sliding structure of the first slide rail assembly 6, the second slide rail assembly 7, and the third slide rail assembly 8 ensures smooth pushing and pulling of the door panel 2. The bending design of the anti-scratch side edge 9 not only prevents users from being scratched when cleaning, but also improves user experience and safety.

[0070] The scratch-resistant side edge 9 is connected to the second guide rail side edge 72 through the arc-shaped side edge 91 to form a smooth transition curved surface. When the second slide rail assembly 7 slides, it guides and covers the side gap between the second slide rail assembly 7 and the first slide rail assembly 6. The arc structure eliminates the risk of burrs cutting hands. The vertical side edge 92 is set parallel to the third slide rail body 81 and is connected to the third guide rail side edge 82. When the third slide rail assembly 8 slides, it is close to the side of the second slide rail assembly 7 through the vertical extension surface, forming a double-layer sealing protection, further preventing the burrs on the side edge of the third slide rail body 81 from being exposed. The composite design of the scratch-resistant side edge 9 achieves side protection of the slide rail after the slide rail sleeve is eliminated, which improves the assembly efficiency and user cleaning safety.

[0071] The disinfection cabinet includes a sliding rail structure that improves the stability of the linear sliding trajectory; the elimination of the sliding rail cover and exposed screws eliminates the risk of burrs cutting hands; and the door panel 2 improves the smoothness of pushing and pulling, structural durability, appearance flatness, and cleaning safety.

[0072] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
