Technical Field

[0001] This utility model belongs to the field of refrigeration equipment technology, and in particular relates to a slide rail assembly, a drawer assembly, and a refrigeration device. Background Technology

[0002] In modern life and business environments, refrigeration equipment has become an indispensable facility. With continuously upgrading demands, multi-layer drawer-type refrigeration equipment has won widespread favor among specific groups due to its convenient categorization and high space utilization. However, there are currently compatibility issues between the drawers of these pull-out refrigeration units and the sliding rails commonly used in the furniture industry. How to achieve a stable integration of the two while maintaining the refrigeration unit's cabinet structure and the drawer's own design has become a pressing technical challenge.

[0003] Furthermore, in some refrigeration equipment, the drawer structure consists of a shell and a drawer, with the drawer being able to be pulled out and pulled along the front-to-back direction within the mounting cavity of the shell. Currently, there is generally a large gap between the drawer sidewall and the side of the mounting cavity, which not only affects the aesthetics of the drawer structure but also limits the drawer's utilization of the space in the lateral direction of the mounting cavity.

[0026] In modern life and business environments, refrigeration equipment has become an indispensable facility. With continuously upgrading demands, multi-layer drawer-type refrigeration equipment has won widespread favor among specific groups due to its convenient categorization and high space utilization. However, there are currently compatibility issues between the drawers of these pull-out refrigeration units and the sliding rails commonly used in the furniture industry. How to achieve a stable integration of the two while maintaining the refrigeration unit's cabinet structure and the drawer's own design has become a pressing technical challenge.

[0027] Furthermore, in some refrigeration equipment, the drawer structure consists of a shell and a drawer, with the drawer being able to be pulled out and pulled along the front-to-back direction within the mounting cavity of the shell. Currently, there is generally a large gap between the drawer sidewall and the side of the mounting cavity, which not only affects the aesthetics of the drawer structure but also limits the drawer's utilization of the space in the lateral direction of the mounting cavity.

[0028] In view of this, the present invention provides a slide rail assembly 100, which is applicable not only to refrigeration equipment, such as refrigerators (e.g.) Figure 1 and Figure 2 As shown in the figure, it can also be applied to other home appliances that require pull-out drawers, such as disinfection cabinets, steam ovens, dishwashers, wine cabinets, etc. For ease of explanation, all embodiments of this utility model are described using a refrigerator as an example, but this does not constitute a limitation on the application scenarios of the slide rail assembly 100. Its technical principles, structural design and connection methods can be directly or after simple adaptation to the above-mentioned other types of home appliances with pull-out drawers. All extended applications based on the core technical solution of this utility model fall within the protection scope of this utility model.

[0029] Please see Figure 2 , Figure 3 and Figure 5 The slide rail assembly 100 includes a panel 1 and a telescopic slide rail 2. The panel 1 is used to close the front opening 201 of the cavity 200. If the cavity 200 is the inner liner of a refrigerator, the panel 1 is usually equipped with insulation material to reduce the loss of cold air in the cavity 200 after closing the front opening 201, thus ensuring the cooling effect. The telescopic assembly is telescopically arranged in the front-to-back direction. The telescopic assembly can be composed of multiple slide rails, which achieve the telescopic function through mutual nesting and sliding cooperation, so that the drawer 300 of the device can be smoothly moved out or in from the cavity 200.

[0030] Please combine Figure 5 The slide rail assembly 100 also includes a connecting structure 3. The connecting structure 3 connects the panel 1 and the telescopic slide rail 2.

[0031] Through this structural design of the connecting structure 3, the connection between the panel 1 and the telescopic slide rail 2 is achieved, and a reliable support carrier is provided for the drawer 300, ensuring the stability of the drawer 300 during the pulling process. This allows telescopic slide rails used in the furniture industry to be applied to the home appliance field. Because the connecting frame 31, through the structural design of the first connecting part 311 and the second connecting part 312, can effectively adapt the commonly used bottom slide rails in furniture to the equipment cavity 200 and the drawer 300 without changing the original dimensions of the equipment box and the structural parameters of the drawer 300 itself. Specifically, when pulling out the drawer, the user pulls out the panel 1, which drives the connecting frame 31 and the telescopic slide rail 2 fixed to it to move synchronously, thereby causing the drawer 300 to move out of the cavity 200 as the telescopic slide rail 2 extends.

[0032] Furthermore, the top of the telescopic slide rail 2 is used to support the drawer 300. This top-mounted support design reduces the gap between the side wall of the drawer 300 and the side of the cavity 200. Compared to the traditional bottom-mounted slide rail, which requires reserved installation space at the bottom of the drawer and results in excessive gaps on both sides, this invention integrates the telescopic slide rail 2 into the space between the bottom of the drawer 300 and the bottom of the cavity 200. This allows the drawer 300 to be positioned closer to the inner side wall of the cavity 200, improving not only the overall structural compactness and aesthetics but also fully utilizing the space in the left and right directions of the cavity 200, thus increasing volume utilization. Simultaneously, the top-mounted support method, combined with the stable connection of the connecting structure 3, further enhances the drawer 300's anti-tilting ability when pulled out, ensuring smooth and stable operation even under full load.

[0033] Therefore, by adding a connecting structure 3 between the panel 1 and the telescopic slide rail 2, this embodiment of the utility model can adapt to commonly used slide rails in the furniture industry without modifying the original structure of the cavity or the parameters of the drawer 300 itself, solving the problem of cross-domain compatibility. Furthermore, by pulling out the panel 1, the telescopic slide rail 2 and the drawer 300 can move synchronously, ensuring the stability and smoothness of the pulling process, effectively expanding the application scenarios of the slide rail and improving the versatility and practicality of the product. Simultaneously, using the upper part of the telescopic slide rail 2 to support the drawer 300 allows the drawer 300 to be closer to the inner wall of the cavity 200 during the pulling process, significantly reducing the gap between the side wall of the drawer 300 and the side of the cavity. This not only improves the aesthetics of the overall structure but also makes full use of the space in the left and right directions of the cavity 200, improving the volume utilization rate. In addition, the upper-mounted support method, combined with the stable connection of the connecting structure, further enhances the anti-tilting ability of the drawer 300 during pulling, ensuring smooth and stable operation even under full load, providing users with a better user experience.

[0034] In some embodiments, the connecting frame 31 includes a first connecting portion 311 at the front end and a second connecting portion 312 at the bottom end. The front side of the first connecting portion 311 is connected to the panel, and the lower side of the second connecting portion 312 is connected to the telescopic slide rail 2. The rear side of the first connecting portion 311 and the upper side of the second connecting portion 312 form a receiving space to accommodate the drawer 300. The "receiving space" can be understood as the area occupied by the bottom edge of the drawer 300 in the installed state. This space allows the drawer 300 to be stably mounted on the connecting frame 31 while avoiding structural interference with the panel 1 or the telescopic slide rail 2.

[0035] This utility model embodiment provides a connecting frame 31 through the connecting structure 3, adopting a design concept of adapter adaptation and spatial compatibility. On the one hand, through the spatial layout of the first connecting part 311 and the second connecting part 312, a stable connection relationship is established between the panel 1, the telescopic slide rail 2, the equipment chamber 200, and the drawer 300, solving the compatibility contradiction between the furniture industry and the structure of home appliances. On the other hand, through the accommodating space formed by the rear and upper sides of the connecting frame 31, the installation stability and smooth movement of the drawer 300 are ensured, and there is no need to change the original size of the equipment box and the structural parameters of the drawer 300 itself, realizing the low-cost reuse of universal slide rails in the home appliance field.

[0036] In some embodiments, considering the field of refrigeration equipment such as refrigerators, users often need to apply considerable force when pulling out the device panel during actual use, which is particularly inconvenient for the elderly and children. The core reason lies in the pressure difference between the chamber and the outside: when the refrigeration equipment is cooling, the chamber temperature is maintained in a low temperature range of -25°C to 10°C, and the internal air contraction causes the air pressure to be lower than the outside pressure. When the refrigeration equipment is sealed, the panel is subjected to a "negative pressure adsorption" effect, tightly sealing the opening. Users need to overcome considerable resistance to open the panel, which is not only laborious but can also easily lead to impact deformation of the slide rails over time.

[0037] Therefore, the connecting frame 31 (specifically, either the first connecting part 311 or the second connecting part 312) is hinged to one of the panel 1 and the telescopic slide rail 2, and fixedly connected to the other. This design allows the panel 1 to rotate relative to the telescopic slide rail 2 by a flip angle during opening. This "flip angle" is the angle formed between the panel 1 after rotation and the plane of the front opening 201 of the chamber 200. This "flip angle" can be formed by rotating the panel 1 around its left-right axis or by rotating the panel 1 around its up-down axis. Taking the flip angle formed by rotating the panel 1 around its left-right axis as an example, this "flip angle" can also be understood as the angle of the panel 1 relative to the first connecting part 311. Figure 4 In this context, α is used to represent the symbol schematically.

[0038] When panel 1 is rotated to a flip angle, the tight fit between panel 1 and the front opening 201 of chamber 200 is broken, allowing outside air to enter chamber 200 and thus balancing the air pressure difference between chamber 200 and the outside. Once the air pressure difference is balanced, the resistance that the user needs to overcome when pulling panel 1 is greatly reduced, making it easier to open panel 1 and allowing the elderly and children to use the refrigeration equipment conveniently.

[0039] At the same time, this design can effectively reduce the impact on the slide rail. Since there is no need to overcome a large negative pressure suction force when opening panel 1, the impact force on the slide rail is also reduced accordingly, avoiding deformation caused by excessive force over a long period of time, extending the service life of the slide rail, and improving the stability and reliability of the entire slide rail assembly 100.

[0040] In some embodiments, please refer to Figure 7 , Figure 8 and Figure 9 Considering that panel 1 needs to be reset after opening to close the front opening 201 of chamber 200, the folding angle of panel 1 relative to telescopic slide rail 2 is limited. Specifically, the connecting structure 3 also includes a limiting member 32, which is fixedly connected to panel 1 and movably abuts against the first connecting part 311 of connecting frame 31 to limit the flipping angle of panel 1 after rotation relative to telescopic slide rail 2.

[0041] The limiting member 32 is fixedly connected to the panel 1 (e.g., screwed, snap-fit). One end is securely mounted to the corresponding position on the inner side of the panel 1, while the other end extends to the first connecting portion 311 of the connecting frame 31, forming a movable abutment relationship. It is not rigidly fixed, but rather retains a slight allowance for the panel 1 to rotate. Simultaneously, the cooperation between the limiting member 32 and the first connecting portion 311 of the connecting frame 31 limits the maximum range of rotation of the panel 1. Specifically, when the panel 1 begins to rotate, the limiting member 32 moves with the panel 1 and generates relative displacement with the connecting frame 31. As the rotation angle increases, the limiting member 32 gradually contacts the first connecting portion 311 of the connecting frame 31 and abuts against it. When the preset rotation angle is reached, the abutment between the limiting member 32 and the first connecting portion 311 of the connecting frame 31 reaches its limit, thereby preventing the panel 1 from continuing to rotate and ensuring that the rotation angle is not too large.

[0042] The limiting member 32 forms a limiting action by abutting against the first connecting portion 311 of the connecting frame 31, and the methods include at least the following three: First, the limiting member 32 abuts against the edge of the first connecting portion 311 of the connecting frame 31. When the panel 1 rotates, the limiting member 32 slides along the edge of the first connecting portion 311 of the connecting frame 31 until it reaches a specific position on the edge, forming an abutment and restricting further rotation of the panel 1. This abutment method is simple and direct, limiting the rotation angle of the panel 1 by the physical boundary of the edge of the first connecting portion 311 of the connecting frame 31. Second, the limiting member 32 abuts against a specific protrusion or recess on the surface of the first connecting portion of the connecting frame 31. The surface of the first connecting portion 311 of the connecting frame 31 is provided with specially designed protrusions or recesses, and the limiting member 32 cooperates with them during the rotation of the panel 1. When the limiting member 32 reaches the protrusion or recess, the two interact to form an abutment, thereby restricting the rotation angle of the panel 1. The third method, as described in subsequent embodiments, involves a limiting member 32 that is movably inserted through a through hole in the first connecting portion 311 of the connecting frame 31. After passing through the through hole, the limiting member 32 can move within a certain range, and the edge of the through hole restricts the range of motion of the limiting member 32. When the panel 1 rotates, the limiting member 32 moves within the through hole. When it reaches the limit of movement defined by the edge of the through hole, the limiting member 32 abuts against the edge of the through hole, thereby limiting the rotation angle of the panel 1.

[0043] These limiting designs ensure that panel 1 can be smoothly reset after being opened, and prevent damage to the connecting structure 3 due to excessive flipping angle, thereby improving the durability and stability of the entire slide rail assembly 100.

[0044] In some embodiments, please refer to Figure 8 and Figure 9 To ensure reasonable positioning, the structure and connection relationships of the connecting frame 31 were refined. Specifically, the first connecting part 311 is movably abutted against the panel 1, and the second connecting part 312 is fixedly connected to the telescopic slide rail 2; the connecting frame 31 also includes a hinge part 313, which is disposed on the first connecting part 311 or the second connecting part 312 and hinged to the panel 1; wherein, the distance between the front end face of the hinge part 313 and the panel 1 is greater than or equal to the distance between the front end face of the first connecting part 311 and the panel 1; the limiting member 32 is movably abutted against the first connecting part 311.

[0045] Specifically, the distance between the front end face of the hinge portion 313 and the panel 1 is greater than or equal to the distance between the front end face of the first connecting portion 311 and the panel 1. This can be understood as the hinge portion 313 not extending forward relative to the first connecting portion 311 in the front-back direction. This ensures that the first connecting portion 311 abuts against the panel 1, rather than the hinge portion 313, avoiding unnecessary interference or friction between the hinge portion 313 and the panel 1 during rotation, thus guaranteeing smooth rotation of the panel 1.

[0046] In some embodiments, please refer to Figure 5 and Figure 6 In order to enable the panel 1 to rotate relative to the telescopic assembly, a hinge structure is provided for the hinge portion 313 and the panel 1. Specifically, one of the hinge portion 313 and the panel 1 is provided with a hinge shaft 3131, and the other is provided with a hinge hole 11. The hinge shaft 3131 is rotatably disposed in the hinge hole 11.

[0047] If the hinge shaft 3131 is located on the hinge portion 313, a hinge shaft 3131 of suitable size and shape can be machined on the front end face of the hinge portion 313. Simultaneously, a hinge ear extending in the left-right direction is provided on the rear side of the panel 1, and a hinge hole 11 adapted to the hinge shaft 3131 is machined on the hinge ear, allowing the hinge shaft 3131 to be rotatably inserted into the hinge hole 11. Conversely, if the hinge shaft 3131 is located on the panel 1, the hinge shaft 3131 is directly machined on the rear side of the panel 1, and a hinge hole 11 corresponding to the hinge shaft 3131 is provided on the front end face of the hinge portion 313. Both hinge structures are simple and reliable, enabling the panel 1 to rotate flexibly relative to the telescopic component, ensuring that the panel 1 can smoothly form a flip angle when opened.

[0048] In some embodiments, please refer to Figure 8 and Figure 9 The first connecting part 311 includes a first connecting plate 3111, which extends in the vertical and horizontal directions. The front side of the first connecting plate 3111 is movably abutted against the panel 1. The first connecting plate 3111 is provided with a limiting hole 31111, and a limiting member 32 extends along the front-back direction and passes through the limiting hole 31111. There is a movable gap between the limiting hole 31111 and the limiting member 32.

[0049] When panel 1 rotates, the limiting member 32 moves within the limiting hole 31111 along with the movement of panel 1. Due to the play between the limiting hole 31111 and the limiting member 32, panel 1 can rotate freely within a certain range. The rotation of panel 1 is restricted until the limiting member 32 moves to and abuts against the edge of the limiting hole 31111, thereby effectively controlling the rotation angle of panel 1. Furthermore, the first connecting plate 3111 abuts against panel 1, functioning similarly to the limiting member 32. During the rotation of panel 1, the first connecting plate 3111 can sense the positional changes of panel 1 in real time and works in conjunction with the limiting member 32 to control the rotation range of panel 1.

[0050] It is obvious that the size of the gap between the limiting member 32 and the through hole, as well as the distance between the panel 1 and the first connecting plate 3111, directly affect the flexibility of the panel 1's rotation and the accuracy of the limiting. If the gap is too large, the panel 1 may rotate excessively, resulting in inaccurate reset, and may even damage the connecting structure 3; if the gap is too small, the panel 1 will experience greater resistance when rotating, affecting the smoothness of opening and reducing the user experience. Therefore, the size of these gaps and distances must be precisely controlled during the design and manufacturing process.

[0051] Furthermore, the extension of the first connecting plate 3111 in both the vertical and horizontal directions provides a wider support and limiting area for the panel 1. From a mechanical perspective, the movable contact between the first connecting plate 3111 and the panel 1 can evenly distribute the force generated when the panel 1 rotates to various parts, reducing the possibility of excessive local stress. This not only helps to improve the smoothness of the panel 1's rotation but also reduces the risk of component damage caused by local stress concentration.

[0052] In some embodiments, please continue reading Figure 8 and Figure 9 In order to enable the panel 1 to return to a vertical position after rotating relative to the telescopic slide rail 2, an elastic element 33 is added. Specifically, the elastic element 33 is pressed between the panel 1 and the first connecting plate 3111, or the elastic element 33 is pressed between the end of the limiting member 32 and the first connecting plate 3111.

[0053] The elastic element 33 is pressed in such a way that it has a preload before the panel 1 is flipped. When the panel 1 begins to rotate and form a flip angle, the elastic element 33 is further compressed, storing elastic potential energy. When the user releases the panel 1, the elastic element 33 releases the stored elastic potential energy, generating a reverse force that causes the panel 1 to return to its initial position perpendicular to the telescopic slide rail 2.

[0054] In some embodiments, please continue reading Figure 8 and Figure 9The elastic element 33 is a spring, which is sleeved outside the limiting element 32. Sleeving the spring outside the limiting element 32 ensures that the spring will not shift or wobble when it exerts its elastic force, thus ensuring that the direction of its elastic force remains stable.

[0055] The specific working process of the spring is as follows: When the user opens the panel 1 and pushes the panel 1 to rotate around the hinge 313 to form a flip angle, the limiting member 32, which moves synchronously with the panel 1, will further compress the spring; and the first connecting plate 3111 and the panel 1 change from a state of mutual contact to having a certain angle: at this time, if the spring abuts between the panel 1 and the first connecting plate 3111, the angle formed by the two will make the direction of the spring force more in line with the rotation trajectory of the panel 1, avoiding the spring from twisting due to force deviation. At the same time, the rotation of the panel 1 will continuously apply pressure to the spring, so that the spring compression gradually increases as the angle increases; if the spring abuts between the end of the limiting member 32 and the first connecting plate 3111, when the limiting member 32 rotates with the panel 1, it will have its end slightly slide along the surface of the first connecting plate 3111. Combined with the angle formed by the two, the spring is always compressed along the axial direction of the limiting member 32, and there will be no lateral misalignment. During this process, the elastic deformation of the spring continuously increases, and elastic potential energy is continuously stored. The angle formed by the first connecting plate 3111 and the panel 1 provides the spring with a reasonable compression space, which not only prevents the spring from being damaged by excessive compression, but also ensures sufficient potential energy reserves to provide sufficient power for subsequent reset. At the same time, the existence of this angle does not disrupt the synergistic effect between the spring and the limiting member 32. The limiting member 32 can still restrict the spring's deviation, ensuring that the elastic force is always transmitted in the preset direction. When the user releases panel 1, the spring releases its stored elastic potential energy, and the resulting reverse thrust is transmitted along the angle formed between the first connecting plate 3111 and panel 1. If the spring directly abuts against panel 1, the thrust will push panel 1 to rotate in the opposite direction around hinge 313, causing the angle between the two to gradually decrease. If the spring transmits the thrust through limiting member 32, limiting member 32 will synchronously reset panel 1 until the first connecting plate 3111 and panel 1 are restored to the attached state, and panel 1 returns to the initial position perpendicular to telescopic slide rail 2. At this time, the spring also returns to the initial pre-tensioned state, completing the entire reset process.

[0056] After testing, the opening force of panel 1 is approximately 60-70N, and the normal, slightly higher pulling force is approximately 20-30N. Therefore, the preload of the spring can be designed to be around 30N, and the spring can also be finely adjusted through the end of the limiting member 32.

[0057] In some embodiments, please continue reading Figure 8 and Figure 9The limiting member 32 adopts a screw connector 321. Specifically, the screw connector 321 is screwed to the panel 1, and the elastic member 33 is sleeved on the stud of the screw connector 321 and abuts between the nut of the screw connector 321 and the first connecting plate 3111.

[0058] When the elastic element 33 is fitted onto the stud of the threaded connector 321 and abuts against the nut of the threaded connector 321 and the first connecting plate 3111, the nut restricts the position of the elastic element 33, preventing it from slipping off the stud during extension and retraction. Simultaneously, the nut can adjust the preload of the elastic element 33. By rotating the nut, the distance between the nut and the first connecting plate 3111 can be changed, thereby altering the degree of compression of the elastic element 33 and adjusting its preload. This allows for flexible adjustment of the spring's elastic properties to achieve optimal performance in different application scenarios and requirements.

[0059] In practical use, when panel 1 rotates to form a flip angle, screw connector 321 moves with panel 1, and elastic element 33 is further compressed, storing elastic potential energy. When the user releases panel 1, elastic element 33 releases its elastic potential energy, and the resulting reverse thrust is transmitted to panel 1 through screw connector 321, pushing panel 1 to rotate in the opposite direction around hinge 313, so that panel 1 returns to its initial position perpendicular to telescopic slide rail 2. In this process, screw connector 321 not only plays a limiting role but also acts as a bridge for the transmission of elastic force, ensuring the smooth reset of panel 1.

[0060] In some embodiments, please continue reading Figure 8 and Figure 9 To facilitate the fixed connection between the connecting frame 31 and the telescopic slide rail 2, the second connecting part 312 includes a second connecting plate 3121. Specifically, the second connecting plate 3121 is integrally formed by extending from the rear side of the first connecting plate 3111, and the extension direction is simultaneously along the front-back direction and the left-right direction. Extending along the front-back direction ensures that the second connecting plate 3121 can be adapted to the length direction of the telescopic slide rail 2, while extending along the left-right direction increases the contact area with the telescopic slide rail 2, facilitating fixation. In terms of connection implementation, the fixed connection between the second connecting plate 3121 and the telescopic slide rail 2 can be achieved through various methods such as bolt connection, welding, and snap-fit ​​connection. If bolt connection is used, threaded holes or through holes that match the mounting holes of the telescopic slide rail 2 can be pre-set on the second connecting plate 3121. Bolts are passed through the holes and tightened, thereby forming a stable whole between the connecting frame 31 and the telescopic slide rail 2. If welding is used, a permanent connection is formed between the contact surfaces of the second connecting plate 3121 and the telescopic slide rail 2 through high-temperature fusion, which is suitable for occasions with extremely high requirements for connection strength. Figure 9 The image shows two connection methods: bolt connection and snap-fit ​​connection.

[0061] In some embodiments, please refer to Figure 3 and Figure 5 The first connecting part 311 of the connecting bracket 31 is fixedly connected to the panel 1, and the second connecting part 312 of the connecting bracket 31 is fixedly connected to the telescopic slide rail 2. These fixed connections can all be made by screwing and / or snap-fitting.

[0062] Specifically, if a screw connection is used, screw holes can be made at corresponding positions on the first connecting part 311 and the panel 1, and the two can be fastened together with bolts. Alternatively, a snap-fit ​​connection can be used, with a hook on the first connecting part 311 and a corresponding slot on the panel 1, allowing for quick connection through the cooperation of the hook and slot. For the fixing of the second connecting part 312 to the telescopic slide rail 2, either a screw connection or a snap-fit ​​connection can be selected according to actual needs. A screw connection provides higher connection strength and stability, while a snap-fit ​​connection facilitates installation and disassembly. When using both methods in combination, the snap-fit ​​connection can be used for pre-positioning, followed by further reinforcement with a screw connection, ensuring the reliability of the connection between the connecting frame 31 and the panel 1 and the telescopic slide rail 2. This fixed connection structure allows the connecting frame 31 to stably transmit the force between the panel 1 and the telescopic slide rail 2, preventing the panel 1 from shaking or malfunctioning due to loose connections during the use of the drawer assembly.

[0063] This utility model embodiment also provides a drawer assembly.

[0064] Please see Figure 9 and Figure 10 The drawer assembly includes a slide rail assembly 100 and a drawer 300, which are removably mounted above the second connecting plate 3121 of the connecting bracket 31. The specific mounting methods are varied. For example, the bottom of the drawer 300 can be designed with a groove that adapts to the second connecting plate 3121. The sliding engagement of the groove with the second connecting plate 3121 allows the drawer 300 to be detachably mounted on the connecting bracket 31. This design allows the drawer 300 to slide left and right along the second connecting plate 3121, facilitating its movement in and out. Alternatively, one of the second connecting plate 3121 and the drawer 300 may have a positioning hole 31211, and the other may have a positioning post 301. The precise engagement of the positioning post 301 with the positioning hole 31211 allows for a detachable connection between the drawer 300 and the second connecting plate 3121. After the positioning post 301 is inserted into the positioning hole 31211, the drawer 300 can be securely placed on the second connecting plate 3121, and can be easily disassembled by lifting it upwards when needed.

[0065] Specifically, the second connecting plate 3121 is provided with a positioning hole 31211, while the bottom of the drawer 300 is designed with a downwardly extending positioning post 301. This positioning post 301 can be flexibly removed and can be securely inserted into the positioning hole 31211. Furthermore, the lower end of the positioning post 301 is tapered. This tapered design makes it easier for the positioning post 301 to be inserted into the positioning hole 31211. During operation, even if there is a certain deviation in the initial alignment between the positioning post 301 and the positioning hole 31211, the tapered lower end can still guide the positioning post 301 to slide smoothly into the positioning hole 31211.

[0066] This utility model embodiment also provides a refrigeration device. This refrigeration device can be a refrigerator, freezer, ice maker, refrigerated cabinet, or similar equipment.

[0067] Please see Figure 2 and Figure 3 The refrigeration equipment includes a main body 400, a drawer 300, and a slide rail assembly 100 provided in any of the above embodiments. The main body 400 has a chamber 200 with a front opening 201; the drawer 300 is installed within the chamber 200; the panel 1 of the slide rail assembly 100 closes the front opening 201 of the chamber 200; the fixed portion of the telescopic slide rail 2 of the slide rail assembly 100 is fixedly connected to the chamber 200, and the movable portion of the slide rail assembly 100 carries the drawer 300, allowing the drawer 300 to move in or out of the chamber 200. (And combined with...) Figure 9 The bottom edge 302 of drawer 300 extends downward to cover the telescopic slide rail 2.

[0068] Because the drawer slide assembly 100 is concealed by the bottom edge 302 of the drawer, the device appears cleaner and more aesthetically pleasing when viewed from the side while the drawer is being pulled out, avoiding any negative impact on the overall visual effect caused by exposed slide assembly 100. Furthermore, during actual use, the downward extension of the bottom edge 302 provides some protection, effectively reducing the risk of damage to the telescopic slide 2 due to accidental collisions during daily use. Simultaneously, the downward extension of the bottom edge 302 effectively prevents dust and debris from entering the telescopic slide 2 during the process of the drawer 300 moving out or in from the cavity 200. The telescopic slide 2 is a crucial component ensuring smooth drawer movement; if dust or debris enters, it may affect the slide's sliding performance, causing the drawer to open or close unevenly, or even damaging the slide.

Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
