[0040] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0041] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0042] Please participate Figures 1-8 Drawer slides are typically designed to ensure smooth opening and closing of drawers and are installed on the inside of the drawer, such as the side or bottom. They usually come in two types: double-rail and single-rail.

[0043] After prolonged use, the guide rail will experience wear due to frequent opening and closing. To prevent this wear from affecting the guide rail, lubricating oil is usually applied to the sliding area or ball bearings are used to reduce wear and achieve smooth sliding.

[0044] However, with this sliding mechanism, dust accumulates on the guide rails after opening and closing. Over time, this accumulation affects the smoothness of the guide rails and their usability, causing the drawer 42 to open and close unevenly. Therefore, this application provides a slide rail assembly, including a guide rail assembly comprising guide rail 1 and guide rail 2.

[0045] The guide rail 1 is open on one side, and the guide rail 2 is installed on the inner side. A limit component 3 is provided between the guide rail 2 and the guide rail 1 for connecting the guide rail 1 and the guide rail 2.

[0046] The limiting component 3 includes at least one limiting plate 31, which is adapted to the guide rail 2;

[0047] The limiting plate 31 is curved inward on both sides, and a guide rod 32 is provided at the curved position; the guide rail 2 is curved downward on both sides, and forms an arc with the inward curved part of the limiting plate 31, with a guide rod 32 provided at the arc.

[0048] The slide rail assembly consists of guide rail 1 and guide rail 2. Guide rail 1 is open on one side for easy installation and operation. Guide rail 2 is located inside guide rail 1 to form a sliding track.

[0049] The limiting component 3 is used to connect guide rail 1 and guide rail 2 to ensure their relative positions during use. The limiting component 3 includes at least one limiting plate 31, which is designed to precisely fit the internal structure of guide rail 2 to ensure effective guidance of sliding and prevent derailment or jamming.

[0050] The limiting plate 31 has two sides that curve inward in an arc shape. This design increases the contact area between the limiting plate 31 and the guide rail 2, and also helps to guide the stability during the sliding process. The curved part is also provided with a guide rod 32 to further improve the sliding efficiency and reduce friction.

[0051] The guide rod 32, positioned at the bend, serves to guide and support, ensuring smooth sliding of the slide rail assembly during use. Furthermore, the guide rod 32 can be made of highly wear-resistant materials to extend its service life.

[0052] The guide rail 2 has downward-curving sides, which helps to guide the guide rail 2 and the limiting plate 31 to form an arc structure with openings on both sides. This design can improve the strength of the structure and reduce the risk of damage from external impacts.

[0053] The guide rod 32, located at the arc position, fully supports the curved part of the limiting plate 31, further increasing stability and preventing excessive shaking of the slide rail assembly during transmission, thus maintaining the continuity of sliding.

[0054] By designing the limiting component 3 and the bending structure, the slide rail assembly can effectively prevent shaking and offset during sliding, ensuring the relative stability between guide rail 1 and guide rail 2.

[0055] The curved limiting plate 31 and guide rod 32 design reduces friction and improves the smoothness of sliding, enabling the slide rail assembly to move faster and more smoothly during implementation.

[0056] The guide rod 32, with its curved shape and high wear-resistant material, reduces wear and tear on traditional slide rail assemblies during operation, thus extending the product's lifespan.

[0057] Guide rail 2 and guide rail 1 maintain a fixed distance, and an abutment block 33 is provided at this fixed distance.

[0058] One end of the guide rail 1 is provided with a protrusion, which is used to restrict the contact block 33.

[0059] A gasket 34 is provided on the outer side of the guide rail 2. One or more through holes 514 are provided at the gasket 34, and fasteners are provided at the through holes 514.

[0060] A fixed gap is maintained between guide rail 2 and guide rail 1 to ensure that the slide rail assembly does not move or shift excessively during use. This gap is designed taking into account the sliding characteristics and load requirements of the guide rail to achieve the best sliding effect.

[0061] Abutment blocks 33 are provided at fixed intervals. The design and material of the abutment blocks 33 should ensure that they can withstand a certain amount of impact and friction to prevent the guide rail 2 from disengaging from the guide rail 1 during sliding. The shape and size of the abutment blocks 33 can be adjusted according to actual needs and may be made of polymer or metal materials with good wear resistance and elasticity.

[0062] One end of guide rail 1 is provided with a protrusion. The main function of the protrusion is to restrict the contact block 33 when guide rail 2 slides to a certain position, thereby preventing excessive displacement of guide rail 2 and system failure. The protrusion can be designed in a hemispherical or cubic shape to ensure stable contact with the contact block 33.

[0063] When guide rail 2 slides towards guide rail 1, the protrusion will contact the abutment block 33, limiting the range of movement of guide rail 2, ensuring the safe operation of the slide rail assembly under high load conditions, and also providing a stable feedback mechanism for sliding.

[0064] A shim 34 is provided on the outer side of the guide rail 2. The shim 34 is mainly used to enhance the tightness between the guide rail and the external environment, prevent the intrusion of dust and debris, and provide additional cushioning effect to reduce wear caused by vibration.

[0065] The gasket 34 has one or more through holes 514 for mounting fasteners, such as screws or nuts, to secure the position of the guide rail 2. The design of the through holes 514 should ensure that the fasteners can evenly distribute the load, enhancing the overall structural stability.

[0066] By using a fixed spacing and abutment block 33, the relative position between guide rail 1 and guide rail 2 is kept constant, so that the slide rail assembly is not easily displaced by external interference during use.

[0067] The bumps limit the sliding range of guide rail 2, preventing excessive movement and ensuring the normal operation of the guide rail. Even under high load conditions, it can maintain safety and stability and is less prone to failure.

[0068] The shim 34 effectively prevents dust and debris from entering, extends the service life of the slide rail assembly, and reduces performance degradation caused by contamination.

[0069] The design of the through hole 514, combined with the fasteners, makes the guide rail 2 more secure, ensuring ease and efficiency of installation and enabling rapid equipment assembly.

[0070] The cushioning effect of the shim 34 reduces friction between moving parts, reduces wear, improves the durability of the slide rail assembly, and reduces the frequency and cost of maintenance.

[0071] Example 2:

[0072] This application also provides a drawer including a slide rail assembly, including a drawer assembly 4, the drawer assembly 4 including an outer frame 41 and a drawer box 42, the inner walls of the outer frame 41 are adapted to the guide rail 1 on both sides, the drawer box 42 is placed inside the outer frame 41, and the outer walls of the drawer box 42 are combined with the gaskets 34 and fasteners at the guide rail 2 on both sides.

[0073] A cleaning component 5 is provided on the inner wall of the outer frame 41 between the two guide rails 1 for cleaning the guide rail assembly.

[0074] The drawer assembly 4 includes an outer frame 41 and a drawer box 42. The outer frame 41 serves as the overall support structure, providing a stable mounting position and sliding track for the drawer box 42. The drawer box 42 is responsible for storage and retrieval; it can hold items or other components and its structure needs to be compact and easy to access.

[0075] The inner walls of the outer frame 41 are fitted to the guide rail 1 on both sides, allowing the outer frame 41 to smoothly engage with the slide rail assembly. This design ensures that the guide rail 1 can effectively guide the sliding of the drawer 42, guaranteeing stability during use.

[0076] The inner wall of the outer frame 41 can be connected to the guide rail 1 through an embedded structure or guide groove to increase the stability of the connection. At the same time, the ease of installation is also taken into consideration, and the correspondence between components can be completed quickly.

[0077] The combination of the gaskets 34 and fasteners on both sides of the outer wall of the drawer 42 with the guide rail 2 ensures that the drawer 42 remains stable when sliding in the outer frame 41 and can withstand the weight of the items inside the drawer 42 without deformation.

[0078] Fasteners (such as screws or nuts) are fixed to guide rail 2 by washer 34. In the design, attention should be paid to the material and anti-corrosion treatment of the fasteners to improve their durability and safety.

[0079] A cleaning component 5 is installed on the inner wall of the outer frame 41 between the two guide rails 1. This component can be a brush or scraper type structure, and its main function is to periodically clean the surface of the guide rail assembly to prevent the accumulation of dust and dirt from affecting the sliding performance.

[0080] The material of cleaning component 5 should have good wear resistance and corrosion resistance to ensure that it will not damage the guide rail assembly during the cleaning process, and can be used for a long time.

[0081] Through the adaptation of guide rail 1 to the outer frame 41 and the fastening design of guide rail 2 to the drawer box 42, the drawer assembly can achieve smooth sliding, ensuring that the drawer box 42 is stable and stable during the pulling process.

[0082] The outer frame 41 serves as a load-bearing component, providing excellent support for the drawer box 42. Its design enhances the stability of the entire drawer assembly, making it suitable for use with heavy items.

[0083] The cleaning component 5 ensures that the drawer slides remain clean during use, greatly improving the ease of drawer maintenance and reducing the risk of slippage due to dirt.

[0084] By placing a shim 34 between the drawer 42 and the guide rail 2, sliding friction can be effectively reduced, wear can be decreased, and the service life of the entire system can be extended.

[0085] An auxiliary block 43 is provided at the bottom of the outer frame 41. The auxiliary block 43 is slidably connected to the bottom of the drawer box 42 to maintain the stability of the drawer box 42.

[0086] An auxiliary block 43 is provided at the bottom of the outer frame 41. Its main function is to slide and connect with the bottom of the drawer 42 to ensure that the drawer 42 remains stable when pulled out and pushed in, preventing items from falling or moving due to shaking. The importance of the auxiliary block 43 design lies in providing additional support, making the use of the drawer 42 safer and smoother.

[0087] The auxiliary block 43 can be made of high-strength plastic or rubber material, with good wear resistance and shock resistance. Its shape can be designed as hemispherical, cylindrical or special groove structure to facilitate an effective sliding connection with the bottom of the drawer 42.

[0088] The auxiliary block 43 should be connected to the bottom of the drawer 42 via a sliding contact, possibly designed as a pin-type or roller-type connection, to allow the drawer 42 to slide smoothly when pulled out. This design should ensure that it can withstand certain lateral and longitudinal loads during sliding to guarantee the stability of the drawer 42.

[0089] The surface of the auxiliary block 43 can be specially treated to give it a certain coefficient of friction, thereby providing moderate resistance when the drawer 42 slides, and avoiding sudden movement or loss of control of the drawer 42 due to excessive smoothness.

[0090] To further enhance stability, the auxiliary block 43 can be designed as a reinforcing rib structure connected to the bottom of the outer frame 41, which can effectively distribute pressure and reduce the possibility of deformation when bearing the weight of large items.

[0091] The auxiliary block 43 should be positioned at the center or both sides of the bottom of the outer frame 41 and adjusted according to the design dimensions of the drawer box 42 to ensure that the drawer box 42 remains balanced throughout the sliding process.

[0092] The auxiliary block 43 effectively prevents shaking during the pulling process, making the drawer 42 more stable when sliding and ensuring the safety of items inside the drawer 42.

[0093] The cleaning component 5 includes an airbag assembly 51 and air outlet strips 52 disposed at both ends of the airbag assembly 51. One or more air outlets 53 are installed at the air outlet strips 52 for cleaning the guide rail assembly.

[0094] One side of the air outlet strip 52 is connected to a pipe 54, which is adapted to one end of the airbag assembly 51.

[0095] The airbag assembly 51 includes a frame 511, a flange 512 is provided on the inner side of the frame 511, a limiting region 513 is formed on the inner side of the flange 512, and an airbag is provided at the limiting region 513.

[0096] The inner walls of the frame 511 are provided with through holes 514 on both sides, and the through holes 514 are adapted to the pipe 54.

[0097] The cleaning component consists of an airbag assembly 51 and air outlet strips 52 disposed at both ends of the airbag assembly 51. The airbag assembly 51 is responsible for generating airflow, while the air outlet strips 52 provide cleaning airflow to the guide rail assembly through multiple air outlets 53. This design helps to efficiently clean dust and debris from the guide rail surface and maintain the smooth operation of the slide rail assembly.

[0098] The airbag assembly 51 includes a robust frame 511 made of a material with good corrosion resistance and structural strength to support the normal operation of the airbag. A flange 512 is provided on the inner side of the frame 511 to increase the airbag's sealing performance and ensure that gas leakage is not easily prevented.

[0099] The limiting area 513 formed inside the flange 512 of the frame 511 ensures that the airbag can be stably maintained within this range during inflation, thereby preventing deformation of the airbag during use. The airbag design should take into account the behavior of gas expansion to ensure that the airbag is not damaged during inflation.

[0100] Air outlet strips 52 are located at both ends of the airbag assembly 51 and are provided with one or more air outlets 53. The number and size of these air outlets 53 need to be reasonably arranged according to the cleaning requirements of the guide rail assembly to ensure that airflow can be delivered evenly, thereby achieving the best cleaning effect.

[0101] One side of the air outlet strip 52 is connected to the pipe 54. The material of the pipe 54 should have good air pressure resistance to ensure that no leakage occurs during airflow transmission. The other end of the pipe 54 is installed at one end of the airbag assembly 51 to achieve efficient gas transmission.

[0102] The inner walls of the frame 511 are provided with through holes 514 on both sides. These through holes 514 are adapted to the connected pipes 54 to ensure efficient airflow during the inflation and deflation of the airbag. The size and position of the through holes 514 should be designed to ensure unobstructed airflow and avoid airflow blockage.

[0103] The cleaning component 5 utilizes the airflow generated by the airbag to effectively clean the surface of the guide rail assembly through multiple air outlets 53 in the air outlet strip 52, promptly removing dust and debris and maintaining the good condition of the slide rail assembly.

[0104] The cleaning component 5 is designed to work with drawer automation systems to enable on-demand cleaning, reducing manual cleaning work for users and improving ease of use.

[0105] By using airflow instead of physical brushes or cleaning tools, mechanical friction on the surface of the guide rail assembly is avoided, thereby reducing wear on the slide rail assembly and extending its service life.
