[0025] The present patent will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present patent, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of this patent.

[0026] Reference Figures 1 to 5 This application provides a drawer assembly 10. The drawer assembly 10 includes a drawer 1 and a movable slide rail 2 disposed on the bottom wall of the drawer 1. The movable slide rail 2 includes a slide rail body 21 and a snap-fit ​​member 22. The snap-fit ​​member 22 includes a first snap-fit ​​structure 221 and a second snap-fit ​​structure 222. The snap-fit ​​member 22 is snapped onto the slide rail body 21 through the first snap-fit ​​structure 221. The snap-fit ​​member 22 is snapped onto the bottom wall of the drawer 1 through the second snap-fit ​​structure 222.

[0027] The snap-fit ​​design of the first snap-fit ​​structure 221 of the snap-fit ​​component 22 with the slide rail body 21 facilitates the assembly of the movable slide rail 2, reducing the complexity of the movable slide rail 2's molding and its processing cost. The second snap-fit ​​structure 222 of the snap-fit ​​component 22 snaps onto the bottom wall of the drawer 1, fixing the slide rail body 21 to the bottom of the drawer 1, thus achieving a concealed arrangement of the slide rail body 21. When maintenance or replacement of the slide rail is required, the slide rail body 21 can be easily removed using the snap-fit ​​component 22. If there is a problem with the connection between the snap-fit ​​component 22 and the drawer 1, only the snap-fit ​​component 22 needs to be replaced, without replacing the slide rail body 21, improving the convenience and economy of maintenance. The design of the detachable snap-fit ​​component 22 of the movable slide rail 2 enables quick assembly with the drawer 1, providing strong stability, easy maintenance, and low cost. It also reduces the space occupied on the side of the drawer 1 while facilitating the connection between the slide rail and the drawer 1.

[0028] Reference Figures 1 to 7In one embodiment of this application, the drawer assembly 10 further includes an inner liner 3. A storage chamber 31 is formed inside the inner liner 3, and the drawer 1 is pull-out disposed within the storage chamber 31. The drawer assembly 10 also includes a mounting bracket 4. The mounting bracket 4 is disposed within the storage chamber 31 and located on the left / right side of the drawer 1. The mounting bracket 4 is fixed to the wall of the inner liner 3 and has a side positioning plate 41 opposite to the left / right side wall of the drawer 1. The drawer assembly 10 also includes a fixing member 5. The fixing member 5 is disposed within the storage chamber 31 and fixedly connected to the side positioning plate 41. The fixing member 5 has a lower positioning plate 51 opposite to the bottom wall of the drawer 1. The drawer assembly 10 also includes a fixed slide rail 6. The fixed slide rail 6 is used to cooperate with the movable slide rail 2 and is fixedly connected to the lower positioning plate 51.

[0029] By fixing the mounting bracket 4 to the inner wall of the liner 3 to form a side positioning plate 41, and the lower positioning plate 51 provided by the fastener 5, the accuracy of the horizontal and vertical positions of the fixed slide rail 6 can be ensured. This allows for better cooperation with the movable slide rail 2 at the bottom of the drawer 1, making the drawer 1 less prone to swaying or tilting during the pulling process, resulting in smoother operation. The mounting bracket 4 and fastener 5 can be designed as standardized components, suitable for drawers 1 of different sizes or shapes. The modular design of the mounting bracket 4, fastener 5, fixed slide rail 6, movable slide rail 2, and snap-fit ​​component 22 facilitates disassembly and replacement. If a component is damaged, the relevant component can be quickly replaced without replacing the entire drawer assembly 10, saving maintenance costs.

[0030] Reference Figure 4 and Figure 5 In one embodiment of this application, a slide rail body 21 has a slide groove 211 inside, and the front end of the slide groove 211 has a front opening 212. The snap-fit ​​member 22 includes a first snap-fit ​​part 223 that is inserted into the slide groove 211 through the front opening 212 and a second snap-fit ​​part 224 that closes the front opening 212. The first snap-fit ​​structure 221 is disposed in the first snap-fit ​​part 223, and the second snap-fit ​​structure 222 is disposed in the second snap-fit ​​part 224.

[0031] The first locking part 223 is located inside the slide groove 211, and the second locking part 224 closes the front opening 212 of the slide groove 211, which can securely fix the locking member 22 to the slide rail body 21 and prevent it from loosening or falling off during long-term use. After the front opening 212 of the slide groove 211 is closed by the second locking part 224, the movement trajectory and connecting parts inside the slide groove 211 are protected, preventing external impurities, dust or foreign objects from entering the slide groove 211 and affecting the sliding performance, thus extending the service life of the slide rail. The front opening 212 of the slide groove 211 allows the locking member 22 to be directly inserted from the front end of the slide groove 211, and also allows the locking member 22 to be easily disassembled by reverse operation, which facilitates the disassembly and installation of the locking member 22.

[0032] In one embodiment of this application, the movable slide rail 2 may include a middle slide rail, which is slidably inserted into the groove 211 of the slide rail body 21. A sliding track can be formed inside the middle slide rail. The fixed slide rail 6 is slidably inserted into the sliding track of the middle slide rail. When the drawer 1 is pulled outward, the slide rail body 21 of the movable slide rail 2 moves outward with the drawer 1. When the slide rail body 21 moves outward a certain distance, it will cause the middle slide rail to move outward relative to the fixed slide rail 6. Through the cooperation of one fixed slide rail 6 and two movable slide rails, the smoothness of the drawer 1's pull-out can be ensured while effectively increasing the outward travel of the drawer 1. In other embodiments of this application, the fixed slide rail 6 may also be directly slidably inserted into the groove 211 of the slide rail body 21. The smoothness of the drawer 1's pull-out is achieved through the cooperation of one fixed slide rail 6 and one movable slide rail 2.

[0033] Reference Figures 2 to 5 In one embodiment of this application, the second latching structure 222 is a first latch protruding forward from the second latching portion 224. A second latch 11, which engages with the first latch, is provided on the bottom wall of the drawer 1. The second latch 11 abuts against the bottom surface of the first latch.

[0034] The second latch 11 abuts against the bottom surface of the first latch, effectively preventing the first latch from detaching from the bottom wall of drawer 1 through mechanical limiting, especially preventing the first latch from moving downwards and being dragged out relative to the bottom wall. This tight abutment structure enhances the connection's firmness, ensuring that the bottom wall of drawer 1 and the slide rail system are not easily loosened during operation. The first and second latches 11 achieve quick assembly through direct interlocking, requiring no additional tools. This latch-type connection method reduces assembly complexity and improves production efficiency. During maintenance or replacement, the latch structure can be easily disassembled manually without damaging other parts, reducing maintenance time and costs. The second latch 11 can be integrally formed with the bottom wall of drawer 1.

[0035] Reference Figures 2 to 5 In one embodiment of this application, a vertically penetrating positioning hole 225 is formed inside the first latching portion 223. A clearance opening 214 is formed on the upper wall of the slide rail body 21 to mate with the positioning hole 225. A positioning block 12 is provided on the bottom wall of the drawer 1. The positioning block 12 is inserted into the positioning hole 225 through the clearance opening 214.

[0036] The positioning hole 225 extends through the entire first snap-fit ​​portion 223. The positioning block 12, after being inserted through the clearance opening 214, directly engages with the positioning hole 225 to achieve high-precision positioning, ensuring the accurate installation position of the drawer 1 bottom wall and the slide rail, preventing offset or loosening. The engagement of the positioning hole 225 and the positioning block 12, along with the cooperation of the clearance opening 214 on the slide rail body 21, provides an alignment mechanism for the drawer 1, the movable slide rail 2, and the snap-fit ​​component 22, improving their installation accuracy. The positioning block 12, inserted through the clearance opening 214 into the positioning hole 225, simultaneously engages with the slide rail body 21 and the first snap-fit ​​portion 223, forming a multi-point fixing structure. This improves the overall stability and impact resistance of the connection, effectively preventing lateral displacement or slippage of the drawer 1 during sliding. The positioning block 12 is directly inserted into the positioning hole 225 through the clearance opening 214, and assembly can be completed without additional tools and complicated operations, which greatly improves production efficiency. When maintenance is required, the positioning block 12 can be easily removed by reversing the operation without damaging the movable slide rail 2 or the bottom wall structure of the drawer 1, reducing maintenance costs and optimizing assembly convenience. The positioning block 12 can be integrally formed with the bottom wall of the drawer 1.

[0037] Reference Figure 5 In one embodiment of this application, the first snap-fit ​​structure 221 is a snap-fit ​​groove symmetrically arranged on the left and right side walls of the first snap-fit ​​portion 223. The left and right side walls of the slide rail body 21 are provided with snap-fit ​​protrusions 213 that cooperate with the snap-fit ​​grooves.

[0038] The snap-fit ​​grooves are symmetrically arranged on the left and right side walls of the first snap-fit ​​part 223, forming a double-sided fixation with the snap-fit ​​protrusion 213 of the slide rail body 21. This symmetrical snap-fit ​​design provides a uniform force distribution, effectively improving the stability of the structure. The engagement of the snap-fit ​​grooves and protrusions can be completed by a simple pushing action, eliminating the need for additional fastening steps and improving assembly efficiency.

[0039] Reference Figures 3 to 5 In one embodiment of this application, the bottom wall of the drawer 1 is provided with a limiting rib 13 that abuts against the left and / or right side wall of the slide rail body 21.

[0040] The limiting rib 13 can be integrally formed into the bottom wall of drawer 1. The abutment design between the limiting rib 13 and the side wall of the slide rail body 21 provides additional lateral support for drawer 1, effectively limiting the left and right wobbling of drawer 1 and ensuring that drawer 1 maintains stable operation during the pulling process.

[0041] Reference Figures 3 to 5 In one embodiment of this application, the left and / or right side walls of the slide rail body 21 are provided with a protruding edge 215. The protruding edge 215 is located near the rear end of the slide rail body 21. The bottom wall of the drawer 1 is provided with a protrusion 14 that mates with the protruding edge 215. The protrusion 14 abuts against the bottom surface of the protruding edge 215.

[0042] ReferenceFigure 1 , Figure 2 , Figure 6 In one embodiment of this application, the drawer assembly 10 includes a first drawer, a second drawer 15 located below the first drawer, a first movable slide rail disposed at the bottom of the first drawer, and a second movable slide rail 23 disposed at the bottom of the second drawer 15. A mounting bracket 4 forms a first side positioning plate 411 and a second side positioning plate 412 located below the first side positioning plate 411. The first side positioning plate 411 is opposite to the side wall of the first drawer. The second side positioning plate 412 is opposite to the side wall of the second drawer 15. The drawer assembly 10 includes a first fixing member fixedly connected to the first side positioning plate 411 and a second fixing member 52 fixedly connected to the second side positioning plate 412. The first fixing member has a first lower positioning plate opposite to the bottom wall of the first drawer. The second fixing member 52 has a second lower positioning plate 521 opposite to the bottom wall of the second drawer 15. The drawer assembly 10 also includes a first fixed slide rail cooperating with the first movable slide rail and a second fixed slide rail 61 cooperating with the second movable slide rail 23. The first fixed slide rail is fixedly connected to the first lower positioning plate, and the second fixed slide rail 61 is fixedly connected to the second lower positioning plate 521.

[0043] The first side positioning plate 411 and the second side positioning plate 412 are respectively located on opposite sides of the first drawer and the second drawer 15, effectively preventing left and right wobbling during drawer 1 operation and ensuring smooth pulling. The first lower positioning plate and the second lower positioning plate 521 are respectively located on opposite bottom walls of the first and second drawers 15, forming a rigid support for the bottom of the drawer 1 and improving the stability of the overall structure. The first side positioning plate 411 and the second side positioning plate 412 provide a precise installation benchmark for each drawer 1, allowing the slide rails and fasteners 5 to align quickly and accurately, reducing assembly errors. The precision design of the double-layer slide rail system ensures that each drawer 1 operates synchronously, reducing tilting or jamming during pulling, while also supporting independent use of each drawer 1.

[0044] The design uses a mounting bracket 4 to form two side positioning plates 41, which are used to install two drawers 1 at the same time. The integrated design reduces the number of brackets, saves space, simplifies component design, and allows the double-layer drawers 1 to be arranged closely, achieving higher storage efficiency in a limited space. In addition, it can ensure the precise relative position of the two side positioning plates 41, ensuring the lateral positioning of the two layers of drawers 1. This structure has stronger overall rigidity and stability, and can better support the operation of the two drawers 1.

[0045] In one embodiment of this application, the drawer assembly 10 may include a left mounting bracket and a right mounting bracket. The left mounting bracket may include a left positioning plate opposite to the left side wall of the drawer 1. The right mounting bracket may include a right positioning plate opposite to the right side wall of the drawer 1. The drawer assembly 10 may include a left positioning member fixedly connected to the left positioning plate and a right positioning member fixedly connected to the right positioning plate. The left positioning member may form a left lower positioning plate opposite to the left end of the bottom wall of the drawer 1. The right positioning member may form a right lower positioning plate opposite to the right end of the bottom wall of the drawer 1. The drawer assembly 10 includes a left fixed slide rail mounted on the left lower positioning plate, a right fixed slide rail mounted on the right lower positioning plate, a left movable slide rail slidably engaged with the left fixed slide rail, and a right movable slide rail slidably engaged with the right movable slide rail. The left movable slide rail is mounted on the left end of the bottom wall of the drawer 1. The right movable slide rail is mounted on the right end of the bottom wall of the drawer 1.

[0046] The left and right mounting brackets support the left and right sides of drawer 1 respectively, providing balanced lateral support to ensure smooth operation of drawer 1 during pulling out and preventing tilting or wobbling. The left and right lower positioning plates support the two ends of the bottom wall of drawer 1, distributing the force at the bottom and preventing concentrated stress from a single point, which could lead to deformation or damage to the bottom wall. The left and right movable slide rails are installed at the left and right ends of the bottom wall of drawer 1 respectively, cooperating with the corresponding fixed slide rails 6 to achieve shared load-bearing capacity from both sides. The left and right slide rail systems operate independently, avoiding wear or jamming caused by uneven force on a single side, thus extending the service life of the slide rails. Through the dual-sided positioning and slide rail cooperation formed by the left and right mounting brackets, this design significantly improves the stability, load-bearing capacity, and smooth operation of the drawer 1 system, while optimizing assembly and maintenance convenience and reducing manufacturing and usage costs.

[0047] Mounting bracket 4 can be installed in the inner liner 3 of housing 101 via snap-fit ​​or threaded connection. Fixing member 5 can be fixed to mounting bracket 4 via threaded connection. Fixed slide rail 6 can be fixed to fixing member 5 via snap-fit ​​or threaded connection.

[0048] This application provides a refrigeration device 100, including a housing 101, a storage chamber 31 formed within the housing 101, and a door for opening and closing the storage chamber 31. The refrigeration device 100 also includes a drawer assembly 10 as described in any of the above embodiments, wherein the drawer 1 of the drawer assembly 10 is pull-out disposed within the storage chamber 31.

[0049] In this application, the front-back direction refers to the depth direction of the refrigeration equipment 100, the left-right direction refers to the width direction of the refrigeration equipment 100, and the up-down direction refers to the height direction of the refrigeration equipment 100. Specifically, the opening direction of the storage compartment 31 is front, and the direction opposite to the opening direction of the storage compartment 31 is rear. The storage compartment 31 can be a refrigerator compartment. A refrigerator compartment is used to store most foods that require refrigeration, such as dairy products, cooked foods, fruits, and vegetables. The storage compartment 31 can also be a freezer compartment. A freezer compartment is used to store foods that require freezing, such as meat, seafood, and frozen foods, to maintain their freshness for a longer period.

[0050] Storage compartment 31 can also be a variable temperature compartment. A variable temperature compartment is a multi-functional storage space designed to provide adjustable temperature settings to adapt to the preservation needs of different foods. The temperature of the variable temperature compartment can be adjusted according to the user's needs, and it can be used as a refrigerator, a low-temperature preservation compartment, or a freezer. When additional refrigeration space is needed or more freezing space is temporarily required, the variable temperature compartment of the refrigeration unit 100 provides extremely high flexibility, allowing users to adjust the appropriate temperature according to different food types and preservation needs, thereby maintaining the optimal freshness and quality of the food.

[0051] Storage room 31 can also be a room of other types besides a refrigerator, freezer, or variable temperature room.

[0052] The refrigeration equipment 100 of this application refers to a mechanical system or device used to reduce and control the temperature of an object or space. Based on its ability to reduce the temperature of a space or object, the refrigeration equipment 100 is widely used in homes, businesses, and other locations.

[0053] In one embodiment of this application, the refrigeration device 100 may refer to a refrigerator. A refrigerator is one of the most common refrigeration devices 100 in households, used to preserve food, prevent spoilage, and extend its shelf life.

[0054] In one embodiment of this application, the refrigeration equipment 100 may refer to a display case.

Freezers are typically designed with large capacity, easy access, and a consistently low temperature environment in mind, making them ideal for storing large quantities of frozen foods, especially perishable items such as meat, seafood, frozen foods, and frozen vegetables. For users who need to store large quantities of frozen foods, such as large families, restaurant owners, or retailers, freezers provide ample storage space. Compared to refrigerators, which are opened frequently, freezers are opened less often, which helps maintain a stable internal temperature and reduces energy consumption.

[0056] The drawer assembly 10 and the refrigeration device 100 having the present application can solve the problem of the drawer slide occupying the side space of the drawer 1.

[0057] By adopting the technical solution of this application, the design of the detachable snap-fit ​​part 22 of the movable slide rail 2 enables quick assembly with the drawer 1, which is stable, easy to maintain, and low in cost. It can reduce the space occupied on the side of the drawer 1 while facilitating the connection between the slide rail and the drawer 1. By fixing the mounting bracket 4 to the inner wall of the inner liner 3 and forming a side positioning plate 41, and the lower positioning plate 51 provided by the fixing part 5, the accuracy of the horizontal and vertical position of the fixed slide rail 6 can be ensured, so that it can better cooperate with the movable slide rail 2 at the bottom of the drawer 1, making the drawer 1 less prone to swaying or tilting during the pulling process, and making the operation more stable. By having the first snap-fit ​​part 223 located inside the slide groove 211 and the second snap-fit ​​part 224 closing the front opening 212 of the slide groove 211, the snap-fit ​​part 22 and the slide rail body 21 can be firmly fixed, and external impurities, dust or foreign objects can be prevented from entering the slide groove 211, affecting the sliding performance and extending the service life of the slide rail. The positioning block 12 is inserted into the positioning hole 225 through the clearance opening 214, and simultaneously engages with the slide rail body 21 and the first snap-fit ​​part 223 to form a multi-point fixing structure, which improves the overall stability and impact resistance of the connection and effectively prevents the drawer 1 from lateral displacement or slippage during sliding. A mounting bracket 4 forms two side positioning plates 41 for simultaneously mounting two drawers 1. The integrated design reduces the number of brackets, saves space, simplifies component design, and allows the double-layer drawers 1 to be arranged closely, achieving higher storage efficiency in a limited space. The left and right mounting brackets support the left and right sides of the drawer 1 respectively, providing balanced lateral support to ensure smooth operation of the drawer 1 during pulling and avoiding tilting or shaking.
