Figure 2 It is the side view of one embodiment of the sliding assembly provided by the embodiments of the utility model. Figure 3 It is the structure exploded schematic view of one embodiment of the sliding assembly provided by the embodiments of the utility model.

[0040] Referring to Figures 1 to 3 The utility model embodiment provides a kind of sliding assembly, which includes slide rail 10 and at least one sliding component 20, at least one sliding component 20 is at least one sliding component 20, can also be two sliding components 20, three sliding components 20 etc.

[0041] The slide rail 10 is suitable to be mounted to a fixed carrier, which can be a main body of furniture or a main body of a refrigerator, and the slide rail 10 is internally configured with a slide groove 11 along the length direction; at least one sliding component 20 is suitable to be connected to a moving carrier and is suitable to freely slide along the extension direction of the slide groove 11; the sliding component 20 comprises a plastic sliding block 21 and a rigid support 22, the plastic sliding block 21 is clamped in the slide groove 11, and the rigid support 22 is embedded in the interior of the sliding block 21. The support 22 serves to provide support strength for the sliding block 21, especially when the moving carrier carries heavy materials, so as to prevent the sliding block 21 from being deformed due to excessive force and ensure the overall stability and reliability of the sliding assembly.

[0042] The slide rail 10 can be made of high-strength metal or alloy steel, and is manufactured by rolling process to ensure the dimensional accuracy and surface flatness of the internal slide groove 11. The slide rail 10 can be in a long strip structure, and the cross-sectional shape of the slide groove 11 can be rectangular. The slide groove 11 is provided with a flange 12 on both sides, which can provide stable support and guidance for the sliding block 21. The flange 12 is used to limit the sliding block 21 and prevent it from coming out of the slide groove 11. The size of the slide groove 11 should ensure that the sliding block 21 can freely slide in the slide groove 11 without excessive shaking.

[0043] The slide rail 10 can be mounted on the door body or cabinet body (i.e. the fixed carrier) of furniture (such as a cabinet) or household appliances (such as a refrigerator) by means of bolts and positioning pins. The threaded holes and positioning holes for fixing the slide rail 10 are pre-processed on the door body or cabinet body. During installation, the slide rail 10 is initially positioned by the positioning pin, and then the bolt is tightened to ensure that the slide rail 10 is firmly fixed on the fixed carrier, avoiding loosening or displacement.

[0044] The sliding block 21 is made of engineering plastic, which has good self-lubricating and shock-absorbing properties, can reduce the friction between the sliding block 21 and the slide groove 11, and reduce the operating noise. The support 22 is made of high-strength metal or aluminum alloy, which can enhance the carrying capacity of the sliding block 21.

[0045] It can be understood that the sliding assembly provided by the embodiment of the utility model, by setting the sliding component 20 as including the plastic sliding block 21 and the rigid support 22, the sliding block 21 is clamped in the sliding groove 11, and the support 22 is embedded in the inside of the sliding block 21. In the use process of the sliding assembly, the plastic sliding block 21 cooperates with the sliding groove 11 in the slide rail 10 to slide, has good self-lubricating property and damping performance, can reduce the friction resistance between the sliding block 21 and the sliding groove 11, and reduces the running noise; and the rigid support 22 is embedded in the inside of the sliding block 21, compensates for the weak load-bearing capacity of the plastic sliding block 21, and can enhance the load-bearing capacity of the sliding block 21. That is to say, the sliding assembly provided by the embodiment of the utility model not only can reduce the friction resistance between the sliding block 21 and the sliding groove 11, and reduces the running noise; and the rigid support 22 is embedded in the inside of the sliding block 21, compensates for the weak load-bearing capacity of the plastic sliding block 21, and can enhance the load-bearing capacity of the sliding block 21.

[0046] And, compared with other existing sliding assemblies, the sliding assembly provided by the utility model has simple structure, less parts, is more convenient to use and install, and has high practicality.

[0047] Figure 4 It is the structural schematic view of the sliding block in the embodiment of the sliding assembly provided by the utility model.

[0048] Continuously referring to Figure 3 And simultaneously referring to Figure 4 In some embodiments of the utility model, the sliding block 21 includes the sliding sub-block 211 and the connecting sub-block 212 connected with each other, the limiting step 213 is formed between the sliding sub-block 211 and the connecting sub-block 212, the limiting step 213 is clamped in the groove wall of the sliding groove 11, plays the role of limiting the sliding range of the sliding block 21 in the sliding groove 11, prevents the sliding block 21 from being taken out of the sliding groove 11, and ensures the safety and stability of the shelf or drawer in the sliding process. Equivalently, the sliding block 21 is in the shape of "T" as a whole, and the shape of the sliding groove 11 is also inverted "T".

[0049] The sliding block 211 is in the shape of a cuboid as a whole, and the length of the sliding block 211 is determined according to the width of the shelf or the drawer. The interior of the sliding block 211 is provided with a groove 2111 in the length direction, and the interior of the sliding block 211 is constructed with a receiving cavity 2112, which is communicated with the groove 2111, and the shape of the receiving cavity 2112 is adapted to the shape of the supporting piece 22, and the supporting piece 22 is embedded into the receiving cavity 2112 from the groove 2111. The supporting piece 22 plays a role of enhancing the structural strength of the sliding block 21 in the receiving cavity 2112, especially when the shelf or the drawer bears heavy objects, can share part of the weight, prevent the sliding block 21 from being deformed due to excessive force, and prolong the service life of the sliding block 21. The groove 2111 provides an installation channel for the supporting piece 22, and also helps to reduce the weight of the sliding block 21 and reduce the production cost.

[0050] The connecting block 212 and the sliding block 211 can be connected together through an injection molding integrated forming process, to ensure the connection strength and integrity between the two. The connecting block 212 is provided with a mounting hole 2121, and the interior of the mounting hole 2121 is provided with a thread, and the mounting hole 2121 is used for fixedly connecting with the shelf or the drawer through a screw. During installation, the connecting block 212 of the sliding block 21 is aligned with the pre-set installation position on the shelf or the drawer, and then a screwdriver is used to screw the screw into the mounting hole 2121, so that the sliding block 21 is firmly installed on the shelf or the drawer. When the drawer or the shelf needs to be moved on the slide rail 10, the sliding block 21 can freely slide along the extension direction of the slide groove 11 with the drawer or the shelf.

[0051] For example, when the user needs to adjust the position (pull out) of the shelf or the drawer, holds the shelf or the drawer and applies a certain external force, since the sliding block 21 is clamped on the inner wall of the slide groove 11, and the limiting step 213 limits the sliding range of the sliding block 21, the shelf or the drawer will smoothly slide along the extension direction of the slide groove 11. During the sliding process, the supporting piece 22 slides in the receiving cavity 2112 along with the movement of the sliding block 21, to provide stable support for the sliding block 21.

[0052] When the shelf is moved to the required position, the user can stop applying force, and at this time the sliding block 21 and the shelf can be kept at the current position, to realize flexible adjustment of the position of the shelf or the drawer. By arranging the supporting piece 22 made of metal in the plastic sliding block 21 to enhance the carrying capacity of the sliding block 21, the overall structure is simple, the number of parts is small, and the sliding block 21 is convenient to use and install.

[0053] In the manufacturing process, the receiving cavity 2112 matched with the shape and size of the supporting piece 22 is pre-processed in the interior of the sliding block 21. Then the supporting piece 22 is embedded into the receiving cavity 2112 through interference fit, to ensure that the connection between the supporting piece 22 and the sliding block 21 is firm and reliable and will not be loose.

[0054] Continue reading Figure 3 and Figure 4 In some embodiments of this utility model, the depth of the groove 2111 is less than the height of the sliding block 211, and the accommodating cavity 2112 extends to the connecting block 212.

[0055] In some embodiments, the receiving cavity 2112 is disposed within the sliding block 211. To further improve structural strength, the receiving cavity 2112 extends from the interior of the sliding block 211 to the connecting block 212, and the support member 22 is located in the receiving cavity 2112.

[0056] In other words, the receiving cavity 2112 extends through the sliding block 211 and the connecting block 212, and the rigid support 22 is located in the receiving cavity 2112. The support 22 is a stable "bridge" established between the sliding block 211 and the connecting block 212. This arrangement not only enhances the connection strength between the sliding block 211 and the connecting block 212, preventing them from separating under long-term use or stress, but also compensates to some extent for the weak connection points that may be caused by the injection molding process or material characteristics. This ensures that the slider 21 can work reliably as a whole structure and better realize the connection function with the shelf or drawer and the slide 11.

[0057] Meanwhile, the rigid support 22 is located within the receiving cavity 2112 that runs through the sliding block 211 and the connecting block 212, which can evenly distribute the load-bearing capacity of the shelf or drawer onto the entire slider 21. Compared to relying solely on the sliding block 211 or the connecting block 212 to bear the weight, this design enhances the overall load-bearing capacity of the slider 21, reduces the risk of deformation or damage caused by local stress concentration, and ensures that the shelf remains stable in the set position when heavy objects are placed on it, without wobbling or falling due to structural issues with the slider 21.

[0058] During long-term use, even if the slider 21 is subjected to external impact or frequent sliding, the rigid support 22 in the accommodating cavity 2112 can help the sliding block 211 and the connecting block 212 maintain their original shape, ensure the matching accuracy between the slider 21 and the groove 11, avoid the phenomenon of poor sliding or jamming caused by the deformation of the slider 21, and thus extend the service life of the entire sliding assembly.

[0059] Continue reading Figure 3 and Figure 4 In some embodiments of this utility model, the width of the groove 2111 gradually decreases from the opening position of the groove 2111 towards the accommodating cavity 2112. This means that the shape of the groove 2111 is trapezoidal, and the width of the bottom of the groove 2111 is the same as the width of the accommodating cavity 2112.

[0060] In other words, the gradually narrowing groove 2111 can provide installation guidance for the rigid support 22. When the rigid support 22 is inserted from the opening of the groove 2111, as the insertion depth increases, the width of the groove 2111 gradually decreases, which restricts the support 22 and naturally causes the support 22 to move towards the center of the accommodation cavity 2112, so as to accurately enter the accommodation cavity 2112, thereby ensuring the consistency and stability of the slider 21 and helping to improve the installation efficiency and reduce human operation errors.

[0061] The width of the bottom of the groove 2111 is the same as the width of the accommodation cavity 2112, so that the rigid support 22 can be closely matched with the accommodation cavity 2112 after entering the accommodation cavity 2112. The support 22 can be effectively prevented from shaking or moving in the accommodation cavity 2112, especially when the slider 21 is subjected to external force impact or vibration, the support 22 can better play its role of enhancing the structural strength, and ensure the stability of the overall structure of the slider 21.

[0062] Figure 5 is a sectional view of an embodiment of the sliding assembly provided by the embodiment of the utility model.

[0063] Continuously referring to Figure 3 and Figure 4 , and referring to Figure 5 , in some embodiments of the utility model, the connecting block 212 is provided with a mounting hole 2121 penetratingly arranged thereon, and the support 22 is provided with a connecting hole 224, the position of the connecting hole 224 corresponding to the position of the mounting hole 2121.

[0064] In this way, the support 22 and the connecting block 212 form a more compact overall structure, improving the overall rigidity of the slider 21. In the face of vibration, impact and the like, the slider 21 can better resist deformation, maintain the stability of its shape and position, and ensure that the shelf or drawer and the like can be smoothly slid and normally used.

[0065] During use, additional connecting members (such as bolts, pins and the like) are arranged corresponding to the mounting hole 2121 and the connecting hole 224, and by inserting the connecting members and performing fastening operation (such as tightening the nut), the support 22 and the connecting block 212 can be firmly connected together. To enhance the stability of the support 22 in the structure of the slider 21, ensure that the support 22 will not easily loosen or move during long-term use and under external force, and maintain the integrity and reliability of the overall structure of the slider 21.

[0066] Referring to Figure 3 and Figure 5In some embodiments of the utility model, the hole wall of connecting hole 224 extends outward to form positioning flange 225, and positioning flange 225 is inserted into mounting hole 2121.

[0067] In this way, positioning flange 225 is tightly matched with mounting hole 2121, and relative dislocation between support piece 22 and connecting block 212 can be effectively prevented after installation. Even if the slider 21 is subjected to external forces such as vibration and impact during operation, the relative position of the support piece 22 and the connecting block 212 can be kept stable by the nesting relationship between the positioning flange 225 and the mounting hole 2121, and the normal operation of the entire sliding assembly can be maintained.

[0068] In other words, the cooperation of the positioning flange 225 and the mounting hole 2121 can play a certain axial and radial positioning role on the support piece 22. During long-term use of the sliding assembly, the support piece 22 can be effectively prevented from loosening due to vibration and shaking, ensuring the durability and stability of the connection, and avoiding problems such as deformation of the slider 21 structure and shaking of the shelf caused by loosening of the support piece 22.

[0069] Continuing to refer to Figure 3 and Figure 4 In some embodiments of the utility model, the sliding surface of the sliding block 211 is provided with a lubricating groove 2113, and the lubricating groove 2113 is filled with a lubricant; the lubricating groove 2113 extends along the length direction of the sliding block 211, and the lubricating groove 2113 extends along the height direction of the sliding block 211.

[0070] The sliding surface of the sliding block 211 can be understood as the surface of the sliding block 211 in contact with the sliding groove 11, that is, the bottom surface and the side surface of the sliding block 211.

[0071] By providing the lubricating groove 2113 filled with the lubricant on the sliding block 211, the lubricant can continuously cover the sliding surface during the entire sliding process, so as to prevent the contact area between the side surface or the bottom surface of the sliding block 211 and the inner wall of the sliding rail 10 from being too large, thereby reducing the jamming and shaking phenomenon during the sliding process, and making the sliding of the shelf or the drawer more stable and smooth.

[0072] The lubricant (grease) can form a lubricating film between the sliding block 211 and the sliding groove 11 in contact therewith, the lubricating film can effectively separate the two relatively moving surfaces, reduce the friction coefficient between the sliding block 211 and the sliding groove 11, and make the sliding block 211 slide more smoothly in the sliding groove 11, thereby reducing the force required to push the shelf or the drawer and improving the convenience of user operation.

[0073] And the lubrication protection can significantly reduce the wear rate of the sliding surface, prolong the service life of the sliding block 211 and the sliding groove 11 matched therewith, reduce the problems of gap enlargement, looseness and the like caused by wear, ensure that the sliding block 21 always has a good working state, reduce friction and vibration in the sliding process, and accordingly reduce noise caused by friction.

[0074] It should be noted that on one sliding surface (i.e. the bottom surface or the side surface) of the sliding block 211, the lubrication groove 2113 can extend along the length direction of the sliding block 211, or the lubrication groove 2113 extends along the height direction of the sliding block 211. The lubrication groove 2113 can also extend along both the length direction and the height direction of the sliding block 211.

[0075] Continuing to refer to Figures 1 to 5 In some embodiments of the present application, the sliding member 20 is equivalent to one, that is, the sliding member 20 is an integral strip-shaped structure, and the length of the sliding block 21 of the sliding member 20 is one-tenth of the length of the sliding rail 10. For example, the length of the sliding rail 10 is about 200 mm, and the length of the sliding block 21 can be about 90 mm, 92 mm or 94 mm.

[0076] In this way, the sliding block 21 can have a suitable stroke range on the sliding rail 10, meet the demand for sliding distance in actual use, and ensure the cooperation precision and stability between the sliding block 21 and the sliding rail 10. For example, in a drawer structure, the drawer can be kept stable during the drawing and pushing processes, and problems such as jamming or disengagement caused by insufficient or excessive stroke of the sliding block 21 can be avoided.

[0077] Moreover, since the contact area between the sliding block 21 and the sliding rail 10 is large, the linear degree and precision can be kept high during linear operation, so as to reduce shaking and deviation and make the sliding block 21 slide more stably. The strip-shaped sliding block 21 is uniformly worn during use, which can reduce the possibility of local wear, prolong the service life of the sliding block 21, and make the sliding block 21 relatively simple to install and replace.

[0078] In the embodiments of the present application, the support member 22 comprises a first support portion 221, a connecting portion 222 and a second support portion 223 connected in sequence, and the first support portion 221 and the second support portion 223 are provided with connecting holes 224. The sliding block 21 is provided with a reinforcing rib 2115 at the position of the connecting portion 222, and the connecting portion 222 is provided with a limiting groove 2222 matched with the reinforcing rib 2115, so that the connecting portion 222 is positioned by cooperation of the reinforcing rib 2115 and the limiting groove 2222. The relative position between the sliding block 21 and the support member 22 is fixed, so as to avoid assembly deviation or misalignment.

[0079] In this way, the assembly efficiency between the sliding block 21 and the support 22 is improved, and the reliability of the sliding component 20 is ensured. The relative displacement between the sliding block 21 and the support 22 during use is effectively prevented. Even when subjected to external forces such as vibration and impact, the sliding block 21 and the support 22 can maintain a stable connection state, ensuring the normal operation of the sliding component 20.

[0080] The first support part 221 and the second support part 223 can be connected to the sliding block 21 through the connecting part, so that the support force is more evenly distributed on the sliding component 20, and the problems such as deformation and shaking during use are effectively prevented. When the sliding component 20 is subjected to a lateral force or an impact force, the first support part 221 and the second support part 223 can jointly resist the external force, and the connecting part 222 plays a role in connecting and transmitting force, so that the entire support 22 can better cope with various complex stress conditions, and ensure the normal operation of the sliding component 20.

[0081] Furthermore, a plurality of reinforcing ribs 2115 are arranged in the sliding block 21, which can enhance the overall strength of the sliding block 21 and prevent deformation during long-term use. That is, the reinforcing ribs 2115 are arranged on the sliding block 21 corresponding to the position of the connecting part 222, which can significantly improve the strength and rigidity of the sliding block 21 in this area. The reinforcing ribs 2115 can increase the sectional moment of inertia of the sliding block 21, so that it is not easy to deform when subjected to external force.

[0082] When the sliding component 20 is subjected to external force, the reinforcing ribs 2115 can disperse the stress concentrated in the connecting part 222 to a larger area, avoid the occurrence of stress concentration phenomenon, improve the fatigue resistance of the entire sliding component 20, and prolong its service life, especially suitable for application scenarios that need to bear large load or frequent use.

[0083] Figure 6 is a structure schematic view of another embodiment of the sliding assembly provided by the embodiment of the utility model. Figure 7 is a structure schematic view of the sliding component in another embodiment of the sliding assembly provided by the embodiment of the utility model. Figure 8 is a sectional view of another embodiment of the sliding assembly provided by the embodiment of the utility model.

[0084] Referring to Figures 6 to 8 In some embodiments of the utility model, when the sliding component 20 is provided with two or more than two, the connecting hole 224 is arranged on each sliding component 20.

[0085] In the embodiment of the utility model, at least two smaller square sliding blocks 21 and sliding rails 10 are used to replace the long strip-shaped sliding block 21 and sliding rail 10.

[0086] In some application scenarios, such as large drawers, multi-layer shelves, etc., multiple sliding components 20 need to work together to ensure smooth and synchronous movement. By providing a connecting hole 224 on each sliding component 20 and connecting it to the drawer or shelf using a connecting piece (such as a bolt, etc.), each sliding component 20 is restricted and linked during movement. When one of the sliding components 20 is subjected to an external force and begins to slide, the other sliding components 20 slide synchronously, thereby ensuring smooth operation of the entire sliding assembly.

[0087] For example, in a shelf carrying heavy objects, each sliding component 20 shares a portion of the weight, allowing the load to be evenly distributed across the sliding components 20, preventing damage from excessive pressure on a single sliding component 20, and improving the load-carrying capacity of the sliding assembly.

[0088] The utility model embodiment further provides a household appliance, the household appliance includes the sliding assembly of any item and cabinet body, the cabinet body is the fixed carrier of the sliding assembly, and the shelf or drawer connected with the cabinet body through the sliding assembly is the moving carrier of the sliding assembly.

[0089] The household appliance can include furniture and household appliances, and the furniture can be a wardrobe, shoe cabinet, or any other storage cabinet, etc. The household appliance can be a refrigerator, a washing machine, and a dishwasher, etc. When the sliding assembly is applied to a dishwasher, the sliding assembly can be used to realize the sliding of the basket shelf on the inner wall sliding groove 11 of the dishwasher.

[0090] Finally, it should be noted that: the above embodiments are only used to illustrate the utility model, and not to limit the utility model. Although the utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the utility model do not deviate from the spirit and scope of the utility model, and should be covered in the scope of the claims of the utility model.
