DETAILED DESCRIPTION

[0042] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0043] like Figures 1 to 5 As shown, the first embodiment of the utility model provides a guide structure for a shelf 108, including:

[0044] A fixing frame 100 is installed on the cabinet;

[0045] A slide rail 102 is mounted on the fixing frame 100 and a slide groove 104 is formed in the slide rail 102;

[0046] Slide block 106 for mounting shelf 108;

[0047] The pulley 110 includes a pin 112 and a self-lubricating sleeve 114 . The pin 112 is connected to the slider 106 , and the self-lubricating sleeve 114 is slidably embedded in the slide groove 104 .

[0048] According to the guide structure for the shelf 108 provided by the embodiment of the first aspect of the utility model, by installing the fixed frame 100 on the cabinet body and the slide rail 102 on the fixed frame 100, a reliable guide is provided for the slider 106 and the pulley 110. This arrangement not only ensures the stability and load-bearing capacity of the shelf 108, but also makes the installation process simpler and faster. The combination of the slide groove 104 and the pulley 110 makes the sliding smoother. The pulley 110 includes a pin 112 and a self-lubricating sleeve 114, the pin 112 is connected to the slider 106, and the self-lubricating sleeve 114 is slidably embedded in the slide groove 104. This arrangement greatly reduces the friction and resistance during sliding, so that the movement of the slider 106 on the slide rail 102 is smoother, and the stability and smoothness of the lifting and lowering of the shelf 108 are improved. Among them, the setting of the self-lubricating sleeve 114 makes the guide structure for the shelf 108 more durable and easy to maintain. The self-lubricating sleeve 114 has excellent lubrication performance and can maintain lubrication during long-term use, reducing wear and failure caused by friction. At the same time, the design of the self-lubricating sleeve 114 also reduces the need for external lubricants, thereby simplifying maintenance procedures and reducing maintenance costs. The guide structure for the shelf 108 also has high flexibility and adaptability to meet different usage requirements.

[0049] Please continue to see Figures 1 to 5 In the embodiment of the utility model, the fixing frame 100 is the basic part of the guide structure. The fixing frame 100 is used to be installed on the cabinet. The fixing frame 100 has a stable structure and can ensure the stability of the entire guide structure. In terms of installation, the fixing frame 100 is usually connected to the cabinet by bolts or other fasteners to fix it in a predetermined position.

[0050] The slide rail 102 is mounted on the fixed frame 100 to provide a sliding track for the slider 106. A slide groove 104 is formed inside the slide rail 102, and the slide groove 104 is used to accommodate the pulley 110 to guide and limit the movement of the pulley 110.

[0051] Thus, the stability of the entire guide structure is ensured by the coordinated installation of the fixing frame 100 and the slide rail 102. This enables the shelf 108 to remain stable during the sliding process and not easily shake or tilt.

[0052] The shelf 108 is connected to the guide structure through the slider 106, so that the shelf 108 can slide on the slide rail 102. A connecting structure is provided inside the slider 106 for installing and fixing the pulley 110. Specifically, the pulley 110 includes a pin 112 and a self-lubricating sleeve 114, wherein the pin 112 is connected to the slider 106 to fix the pulley 110 and transmit force. The self-lubricating sleeve 114 is slidably embedded in the slide groove 104 of the slide rail 102.

[0053] The self-lubricating sleeve 114 is made of a plastic-coated material such as POM, which has excellent lubrication properties and can significantly reduce the friction resistance during sliding. Due to the design of the pulley 110 using the self-lubricating sleeve 114, the sliding of the slider 106 on the slide rail 102 becomes very smooth. The self-lubricating sleeve 114 can significantly reduce the friction resistance during sliding, reduce the jamming and resistance phenomenon, and make the movement of the shelf 108 easier. The self-lubricating sleeve 114 has excellent wear resistance and durability, and can maintain good lubrication properties for a long time. This reduces the failure and replacement frequency caused by friction and wear, and reduces maintenance costs. In addition, the design of the self-lubricating sleeve 114 also reduces the need for external lubricants, simplifies the maintenance procedures, and makes the maintenance of the guide structure easier.

[0054] In addition, due to the detachable design of the slider 106 and the pulley 110, the shelf 108 can be adjusted or replaced as needed. This makes the guide structure highly flexible and can adapt to the needs of shelves 108 of different specifications and layouts.

[0055] At the same time, the guide structure is also suitable for different types of cabinets, especially for wide cabinets, and has strong adaptability.

[0056] According to one embodiment of the present invention, the slider 106 includes:

[0057] The connecting section 116 corresponds to the position of the slide slot 104, and the pin 112 is connected to the connecting section 116;

[0058] The bent positioning section 118 is connected to the connecting section 116 and is bent toward a side of the slide rail 102 away from the slide groove 104 , with a gap formed between the bent positioning section 118 and the slide rail 102 .

[0059] See also Figure 3In the embodiment of the utility model, the design of the connecting section 116 corresponds to the position of the slide groove 104, and the pin 112 is connected to the connecting section 116. Therefore, when the pulley 110 slides in the slide groove 104, the connecting section 116 can ensure the stable movement of the slider 106 and effectively help to bear the gravity of the shelf 108 itself and the food on the shelf 108. The pin 112, as a connecting component connecting the slider 106 and the pulley 110, ensures that the pulley 110 can move smoothly in the slide groove 104, thereby realizing the smooth sliding of the shelf 108.

[0060] The bent positioning section 118 is connected to the connecting section 116 and is bent toward the side of the slide rail 102 away from the slide groove 104. This arrangement not only increases the stability of the slider 106, but also enables the slider 106 to be better positioned with the slide rail 102 during the sliding process. A certain gap is formed between the bent positioning section 118 and the slide rail 102, which can prevent the slider 106 from excessively deflecting or shaking during the sliding process to a certain extent, further improving the stability of the shelf 108.

[0061] In addition, the problem of wear of the slider 106 during long-term use is also taken into consideration by setting the bending positioning section 118 and the slide rail 102 at a distance. Since there is a certain gap between the bending positioning section 118 and the slide rail 102, even if the slider 106 is worn to a certain extent during use, the stability and smooth sliding of the shelf 108 can be ensured, thereby extending the service life of the guide structure.

[0062] According to an embodiment of the present invention, a weight-reducing hole 120 is formed on the bending positioning section 118 .

[0063] See also Figure 3 In the embodiment of the utility model, the design of the weight-reducing holes 120 can significantly reduce the overall weight of the slider 106. Under the premise of maintaining the strength and rigidity of the slider 106, the use of materials can be reduced by opening the weight-reducing holes 120, which can effectively reduce the mass of the slider 106 and make the entire shelf 108 assembly lighter. This not only facilitates the installation and disassembly of the shelf 108, but also reduces the requirements for the load-bearing capacity of the cabinet, thereby improving the applicability of the product. By optimizing the shape and layout of the weight-reducing holes 120, the slider 106 can be made to move more smoothly, reduce the noise caused by the slider 106's own vibration during movement, and enhance the user experience.

[0064] According to an embodiment of the present invention, a limiting member 122 is further included. The limiting member 122 is disposed at both ends of the sliding slot 104 along the length direction of the sliding slot 104 .

[0065] See also Figure 3In the embodiment of the utility model, the main function of the limiter 122 is to limit the movement range of the slider 106, ensuring that the slider 106 does not exceed the boundary of the slide groove 104 during the sliding process. This can effectively prevent the slider 106 from falling off or being damaged due to excessive movement, and enhance the stability and safety of the guide structure. In addition, the setting of the limiter 122 also helps to improve the user experience. Since the movement range of the slider 106 in the slide groove 104 is clearly limited, the user can more accurately control the position of the shelf 108, making it more convenient and quick to take and put items.

[0066] In actual use, the stopper 122 can be in various forms and materials to adapt to different use environments and requirements. For example, the stopper 122 can be a metal block or a plastic block fixed at both ends of the slide rail 102, or a protruding part integrated into the structure of the slide rail 102.

[0067] According to an embodiment of the present invention, a mounting plate 124 is formed on the fixing frame 100 . The mounting plate 124 extends along the height direction of the cabinet, and the slide rail 102 is mounted on the mounting plate 124 .

[0068] See also Figure 3 In the embodiment of the utility model, a mounting plate 124 is formed on the fixing frame 100 , the mounting plate 124 extends along the height direction of the cabinet, and the slide rail 102 is mounted on the mounting plate 124 .

[0069] By setting in this way, the installation of the mounting plate 124 makes the installation of the slide rail 102 easier and more intuitive. The mounting plate 124 serves as a fixed base for the slide rail 102 and provides a stable and solid support for the slide rail 102. The slide rail 102 and the mounting plate 124 can be installed by bolt connection, clamping, etc., so as to ensure the stability of the entire guide structure.

[0070] like Figure 3 As shown, the mounting plate 124 extends along the height direction of the cabinet, so that the position of the slide rail 102 can be flexibly adjusted as needed. Therefore, during actual installation and use, the layout of the shelf 108 can be customized according to the actual use scenario and the size of the cabinet. Whether it is a tall cabinet or a short cabinet, the position of the slide rail 102 on the mounting plate 124 can be adjusted to achieve the best installation effect of the shelf 108.

[0071] In addition, the mounting plate 124 also enhances the structural strength of the fixing frame 100 itself. For example, the mounting plate 124 can be a flange structure formed on the fixing frame 100, thereby forming a structure similar to a reinforcing rib on the fixing frame 100, which can effectively disperse the pressure of the shelf 108 and items on the fixing frame 100, and at the same time reduce the risk of deformation or damage to the cabinet.

[0072] According to one embodiment of the present invention, the slide rail 102 includes:

[0073] A bottom plate 126 , the bottom plate 126 is mounted on the mounting plate 124 ;

[0074] Side plates 128, which are disposed on opposite sides of the bottom plate 126 along the length direction of the bottom plate 126, and the side plates 128 and the bottom plate 126 are surrounded to form the slide groove 104;

[0075] The baffle 130 is disposed at the edge of the side plate 128 along the length direction of the side plate 128 and is bent toward the inner direction of the slide groove 104 .

[0076] See also Figure 4 In the embodiment of the utility model, the slide rail 102 mainly includes three parts: a bottom plate 126, a side plate 128 and a baffle 130. The above three parts together constitute the slide groove 104, providing a stable track for the sliding of the slider 106.

[0077] First, the bottom plate 126 is installed on the mounting plate 124 to ensure the stability of the slide rail 102. The bottom plate 126 and the mounting plate 124 can be connected by bolts. The side plates 128 are arranged on opposite sides of the bottom plate 126 along the length direction of the bottom plate 126, and the side plates 128 and the bottom plate 126 are surrounded to form the slide groove 104. The design of the side plates 128 not only defines the shape and size of the slide groove 104, but also plays a role in limiting the movement range of the slider 106. The side plates 128 and the bottom plate 126 can be formed in an integral manner. This connection method is firm and reliable, ensuring the integrity and stability of the slide groove 104.

[0078] The baffle 130 is arranged at the edge of the side plate 128 along the length direction of the side plate 128 and is bent toward the inner direction of the slide groove 104. This arrangement not only enhances the overall structural strength of the slide rail 102, but also prevents the slider 106 from falling off from the slide groove 104 during the sliding process. The existence of the baffle 130 makes the movement of the slider 106 in the slide groove 104 safer and more stable.

[0079] Therefore, the design of the slide rail 102 not only focuses on the stability and durability of the structure, but also considers the smoothness and safety of the sliding of the slider 106. By optimizing the structure and size of each part of the slide rail 102, the entire guide structure can better meet the needs of users and provide a high-quality user experience.

[0080] According to an embodiment of the present invention, the distance between the two baffles 130 is less than or equal to the diameter of the pulley 110 .

[0081] In the embodiment of the utility model, this arrangement ensures the stable movement of the pulley 110 in the slide groove 104. Since the spacing of the baffles 130 limits the movement range of the pulley 110, the pulley 110 will not fall off from the slide groove 104 during the sliding process, thereby ensuring the stability and safety of the shelf 108.

[0082] At the same time, this arrangement also helps to reduce the shaking and noise of the pulley 110 during the sliding process. When the pulley 110 slides in the slide groove 104, due to the restriction of the baffle 130, the movement trajectory of the pulley 110 is more stable, the noise caused by shaking is reduced, and the user experience is improved. By accurately controlling the spacing of the baffle 130, the pulley 110 can slide smoothly in the slide groove 104, reduce the resistance caused by friction, and improve the sliding efficiency.

[0083] According to an embodiment of the present invention, the slide rail 102 is an aluminum alloy slide rail 102 .

[0084] By configuring the slide rail 102 to be an aluminum alloy guide rail, it can reduce weight on the one hand, and on the other hand, it can ensure that the slide rail 102 has a strong structural strength.

[0085] A second aspect of the present invention provides a shelf 108 assembly, including the guide structure for the shelf 108 as described above.

[0086] According to the shelf 108 assembly provided by the embodiment of the second aspect of the utility model, by providing the above-mentioned guide structure for the shelf 108, it is possible to ensure the smooth lifting and lowering of the shelf 108 and improve the overall structural stability of the shelf 108 assembly.

[0087] The third aspect of the present utility model provides a storage cabinet, including the guide structure for the shelf 108 as described above;

[0088] Or the shelf 108 assembly as described above.

[0089] According to the locker provided in the third aspect of the utility model, by providing the guide structure for the shelf 108 or the shelf 108 assembly, it is possible to ensure the rational use of the space in the locker and the stability of the items placed in the locker.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
