Abstract

This application relates to the field of storage technology, and more particularly to a storage cabinet. The storage cabinet of this application has a drawer that can be pulled out of the storage compartment. The drawer sidewall and the compartment sidewall are connected by a first guide rail and a second guide rail, allowing the drawer to be pulled out relative to the storage compartment. An elastic connector is provided between the front end of the first guide rail and the second guide rail. This elastic connector is configured to elastically deform along the extension direction of the first guide rail when the drawer is pulled outwards, thus pulling the drawer backwards and increasing the resistance to pulling it outwards. This reduces the possibility of the drawer being opened arbitrarily, especially by children, improving the drawer's safety. By providing an elastic locking component at the front end of the first guide rail, when the drawer is pulled outwards, the elastic locking component can engage with a mating hole on the second guide rail to lock the drawer, keeping it in the open position for easy access to items.

Description

Technical Field

[0001] This application relates to the field of storage technology, and more particularly to a storage cabinet. Background Technology

[0002] Refrigerators are common household appliances used to store everyday food. As people's living standards improve, their demands for refrigerator functions are also increasing.

[0003] In related technologies, refrigerators typically have drawers within their compartments, allowing items to be retrieved and stored by pulling them out. However, the increasingly effortless operation of these drawers has led to their easy opening. In particular, children can easily open these drawers, posing a safety hazard. Utility Model Content

[0004] This application provides a storage cabinet that improves the security of drawer pull-out.

[0005] This application provides a storage cabinet, which includes:

[0006] The box body is configured to form a storage compartment with a front opening; the box body includes compartment sidewalls that are opposite to and spaced apart along the width direction of the storage compartment;

[0007] A drawer is removably installed in the storage compartment; the drawer is configured to form an upward-opening storage cavity; the drawer includes drawer sidewalls that are opposite to and spaced apart along the width of the storage compartment;

[0008] Two guide rail assemblies, each of which is disposed between one of the compartment sidewalls and one of the drawer sidewalls; the guide rail assembly includes:

[0009] A first guide rail is fixed to the side wall of the compartment; the first guide rail extends along the depth direction of the storage compartment;

[0010] The second guide rail is fixed to the side wall of the drawer, and the second guide rail is slidably connected to the first guide rail;

[0011] The first guide rail is provided with an elastic connector at its front end facing the opening of the storage compartment, and the end of the elastic connector away from the first guide rail is fixedly connected to the second guide rail; the elastic connector is configured to elastically deform along the extension direction of the first guide rail when the drawer is pulled outward.

[0012] At least one of the first guide rails has an elastic locking component at its front end, and the second guide rail has a mating hole at its rear end; when the drawer pulls the second guide rail outward until the mating hole engages with the elastic locking component, the drawer is locked in the open position.

[0013] The storage cabinet of this embodiment features a drawer that can be pulled out of the storage compartment. The drawer sidewall and the compartment sidewall are connected by a guide rail assembly. The guide rail assembly includes a first guide rail fixed to the compartment sidewall and a second guide rail fixed to the drawer sidewall. The second guide rail is slidably connected to the first guide rail, allowing the drawer to be pulled out relative to the storage compartment. An elastic connector is provided between the front end of the first guide rail and the second guide rail. The elastic connector is configured to elastically deform along the extension direction of the first guide rail when the drawer is pulled out, thus pulling the drawer backward and increasing the resistance to pulling the drawer out, reducing the risk of the drawer being opened at will, especially by children, and improving the safety of the drawer. Moreover, when the drawer is closed, the first elastic connector returns to its original shape, moving the drawer backward into the storage compartment, making the drawer closing operation easier. Furthermore, by providing an elastic locking component at the front end of the first guide rail, when the drawer is pulled out, the elastic locking component can engage with a mating hole provided on the second guide rail to lock the drawer, keeping it in the open position for easy access to items.

[0014] In some embodiments of this application, the resilient connector includes:

[0015] A connecting sleeve, one end of which is fixedly connected to the first guide rail; the connecting sleeve extends along the extension direction of the first guide rail;

[0016] A connecting rod, one end of which is slidably mounted inside the connecting sleeve; the other end of which is fixedly connected to the second guide rail;

[0017] A first elastic element is sleeved on the outside of the connecting rod, and one end of the first elastic element is fixedly connected to the connecting sleeve, and the other end of the first elastic element is fixedly connected to the connecting rod; the first elastic element is configured to elastically deform along the extension direction of the first guide rail.

[0018] The elastic connector in this embodiment connects to the first guide rail via a connecting sleeve and to the second guide rail via a connecting rod. The connecting rod and connecting sleeve are slidably connected, providing space for the elastic deformation of the first elastic element. Furthermore, the cooperation between the connecting rod and the connecting sleeve guides the direction of the elastic deformation of the first elastic element. The first elastic element also increases the resistance when the drawer is pulled outward, reducing the possibility of the drawer being opened arbitrarily. Moreover, the first elastic element can assist in closing the drawer, making it quicker and easier to close.

[0019] In some embodiments of this application, the front end of the first guide rail is provided with a mounting hole, which extends along the height direction of the drawer;

[0020] The resilient locking component includes:

[0021] The second elastic element has one end fixed inside the mounting hole and the other end extending to the top outside the mounting hole;

[0022] A locking head is fixedly connected to the other end of the second elastic member; the locking head is configured to engage with the mating hole when opposite each other along the height direction of the drawer to lock the drawer in the open position.

[0023] With the above configuration, the elastic locking assembly uses a second elastic element to elastically deform along the height direction of the drawer, causing the locking head to compress or extend along the height direction of the drawer, thereby allowing the locking head to engage with or disengage from the mating hole, thus achieving locking and unlocking of the drawer.

[0024] In some embodiments of this application, the second guide rail is configured to form a groove that extends along the depth direction of the storage compartment and opens to one side of the groove facing the first guide rail; along the height direction of the box, the size of the groove is larger than the size of the opening of the groove;

[0025] A portion of the first guide rail is inserted into the slide groove so that the first guide rail slides relative to the second guide rail.

[0026] By setting a groove with an opening on one side of the second guide rail, a portion of the first guide rail can be inserted into the groove to achieve relative sliding between the first and second guide rails. This also ensures that the first and second guide rails are limited in the width direction, preventing them from separating in the width direction.

[0027] In some embodiments of this application, the first guide rail includes:

[0028] The fixing part is fixed to the side wall of the compartment;

[0029] A sliding part is slidably mounted in the slide groove;

[0030] A connecting part connects the fixing part and the sliding part, and the connecting part passes through the opening of the groove;

[0031] The elastic connector is connected to the sliding part, and the elastic locking component is disposed at the top of the front end of the sliding part.

[0032] The first guide rail in this embodiment is fixedly connected to the side wall of the compartment by a fixed part, slidably installed in the slide groove by a sliding part, and connected to the sliding part and the fixed part by a connecting part. The structure is simple and easy to implement.

[0033] In some embodiments of this application, the second guide rail is fixed with a first connecting block, and the first connecting block is located at the front end of the slide groove;

[0034] The other end of the elastic connector is fixedly connected to the first connecting block.

[0035] By setting a first connecting block in the groove of the second guide rail, and connecting the first connecting block with the elastic connecting member, a fixed connection between the elastic connecting member and the second guide rail is achieved. The structure is simple and easy to implement.

[0036] In some embodiments of this application, an elastic buffer assembly is provided between the rear wall of the drawer and the rear wall of the storage compartment.

[0037] By setting up an elastic buffer component, the back wall of the drawer and the back wall of the compartment can make elastic contact, buffering the force when the drawer is closed. This can reduce the expansion force between the drawer and the back wall of the compartment, and also reduce collision noise.

[0038] In some embodiments of this application, the resilient buffer component includes:

[0039] A connecting plate is fixed to the outer side of the rear wall of the drawer; the connecting plate extends along the width direction of the drawer.

[0040] Multiple elastic components are arranged at intervals along the extension direction of the connecting plate.

[0041] The elastic buffer assembly of this application improves the reliability of drawer elastic buffering by setting multiple elastic components to form multiple elastic buffer positions.

[0042] In some embodiments of this application, the elastic component includes:

[0043] The first connecting plate is fixedly connected to the connecting plate;

[0044] The third elastic element is configured to elastically deform along the direction of the drawer's pull-out; one end of the third elastic element is fixedly connected to the first connecting plate;

[0045] An abutment is fixedly connected to the other end of the third elastic member; the abutment is configured to abut against the rear wall of the compartment.

[0046] In this embodiment of the application, the elastic component is fixedly connected to the connecting plate by setting a first connecting plate, abutting the rear wall of the compartment by setting an abutting joint, and a third elastic component is set to connect the first connecting plate and the abutting joint, so that the abutting joint abuts the rear wall of the compartment elastically.

[0047] In some embodiments of this application, the resilient connector is in its natural state when the drawer is in the closed position.

[0048] This reduces the resistance when pulling out the drawer, preventing excessive resistance that could affect ease of use. Furthermore, it avoids fatigue damage to the elastic connectors, which are constantly in a deformed state. The natural state of the elastic connector refers to its free state without elastic deformation.

[0049] In some embodiments of this application, the front ends of the two first guide rails are respectively provided with the elastic locking components, and the rear ends of the two second guide rails are respectively provided with the mating holes.

[0050] This design ensures that the left and right sides of the drawer are locked by elastic locking components, which not only improves the reliability of the locking action but also enhances the uniformity of force distribution on the drawer.

[0051] In some embodiments of this application, a plurality of elastic connectors are provided on the first guide rail, and the plurality of elastic connectors are arranged at intervals along the height direction of the first guide rail.

[0052] In this way, by setting multiple elastic connectors, resistance to the outward pulling of the drawer is ensured, preventing the drawer from being opened arbitrarily; and the elastic force for the drawer to automatically return to its original position is also ensured.

[0070] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0071] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0072] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0073] In related technologies, refrigerators are equipped with drawers within their compartments, allowing items to be retrieved and stored by pulling them out. However, the increasingly effortless operation of these drawers has led to their easy opening. In particular, children can easily open these drawers, posing a safety hazard. When a drawer is pulled out to its maximum position, not only are items prone to falling, but the drawer itself may also slip off due to the shifted center of gravity of the stored items, potentially injuring someone's feet. Furthermore, failing to close drawers promptly can cause cold air to leak out of the refrigerator, affecting the quality of stored goods and leading to spoilage of meat, dairy products, fruits, and vegetables.

[0074] In view of this, the embodiments of this application provide a tension spring on the drawer guide rail to increase the resistance during the process of pulling the drawer out, preventing the drawer from being opened at will, especially by children; and a locking mechanism is provided to lock the drawer in the open state, which not only facilitates the taking and putting of items, but also prevents the drawer from being pinched when closed, thus improving the safety of the drawer.

[0075] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0076] First, it should be noted that in this embodiment, the depth direction of the box corresponds to the Y-axis direction in the figures, and the directional term "front" refers to the side facing the door along the Y-axis direction, while the directional term "rear" refers to the side away from the door along the Y-axis direction. The width direction of the box corresponds to the X-axis direction in the figures, and the height direction of the box corresponds to the Z-axis direction in the figures.

[0077] Reference Figure 1 and Figure 2 This application provides a storage cabinet, which can be a storage structure for low-temperature storage items such as refrigerators, smart wine cabinets, and cigar cabinets.

[0078] The locker in this embodiment includes a cabinet 100, which can be configured to form a storage compartment 101 with a front opening for storing items. The front opening of the storage compartment 101 is a retrieval port.

[0079] Multiple storage compartments 101 can be provided to expand storage space. Depending on the storage temperature of the storage compartments 101, they can include at least one refrigerated compartment and at least one frozen compartment. The internal temperature of the refrigerated compartment can be maintained between approximately 0°C and 5°C for storing items in refrigeration mode; the internal temperature of the frozen compartment can be maintained between approximately -30°C and 0°C for storing items in freezing mode.

[0080] In some possible implementations, at least one of the storage chambers 101 may also be configured as a vacuum chamber or a variable temperature chamber, etc., which will not be described in detail in the embodiments of this application.

[0081] For example, two storage compartments 101 can be provided, which can be stacked vertically or arranged side by side horizontally. One of them can be a refrigerator compartment and the other can be a freezer compartment.

[0082] The cabinet 100 may include a cabinet liner and a cabinet shell. The cabinet liner may be configured to form a storage compartment 101 with a front opening, which serves as an access port. The cabinet shell may be attached to the outside of the cabinet liner to form the appearance of a storage cabinet.

[0083] The cabinet 100 may also include a cabinet insulation layer, which can be disposed between the cabinet liner and the cabinet shell. The cabinet insulation layer can insulate the storage compartment 101 to minimize heat exchange between the storage compartment 101 and the outside of the cabinet, which is beneficial to ensuring the cooling effect of the cabinet.

[0084] The locker in this embodiment may further include a refrigeration system for reducing the air temperature in the storage compartment 101. Exemplarily, the refrigeration system may be housed within the cabinet 100. The refrigeration system may include a compressor, condenser, expansion valve, and evaporator connected in a cycle.

[0085] During refrigeration system operation, the compressor compresses refrigerant vapor to generate high-temperature, high-pressure refrigerant vapor, which is then transported to the condenser. The condenser liquefies the high-temperature, high-pressure refrigerant vapor, generating high-temperature, low-pressure refrigerant liquid, which is then transported to the expansion valve. The expansion valve reduces the pressure of the refrigerant liquid, transforming the high-pressure, low-temperature refrigerant liquid into a low-pressure, low-temperature refrigerant liquid, which is then transported to the evaporator. The evaporator receives the low-pressure, low-temperature refrigerant liquid and boils it under isobaric conditions, absorbing heat and vaporizing to form refrigerant vapor, thereby lowering the temperature inside storage compartment 101.

[0086] Continue to refer to Figure 1 The locker in this embodiment may further include a door 200, which is rotatably connected to the cabinet 100 to open or close the access port. For example, the door 200 is hinged to the cabinet 100.

[0087] Each storage room 101 may be provided with one door 200; or, each storage room 101 may be provided with two doors 200, which may rotate in opposite directions to open or close the storage room 101.

[0088] In some embodiments, the door 200 may include an inner door liner. When the door 200 is closed to the refrigerator compartment, the inner door liner faces the refrigerator compartment.

[0089] The door 200 may include a door outer shell; the door outer shell may be attached to the outside of the door inner liner to form the appearance of the door 200. The door outer shell may be rotatably connected to the cabinet 100 to allow the door 200 to open or close the refrigerator compartment.

[0090] The door body 200 may also include a door insulation component, which can be disposed within the gap between the inner door liner and the outer door shell. The door insulation component can insulate the storage compartment 101 to minimize heat exchange between the storage compartment 101 and the outside of the storage cabinet, thus helping to ensure the cooling effect of the storage cabinet. The door insulation component can be a foam layer.

[0091] Continue to refer to Figure 1 The locker in this embodiment may further include a drawer 300, with a pull-out structure forming an upward-opening storage cavity 301. The drawer 300 is slidably installed inside the storage compartment 101. The drawer 300 is pulled outward through the opening of the storage compartment 101 to open the storage cavity 301, enabling the retrieval and placement of items.

[0092] In some embodiments, refer to Figure 2 The drawer 300 includes a drawer body 310 and a drawer door 320. The drawer body 310 is configured to form an upward-opening storage cavity 301. The drawer door 320 is fixed to the front side of the drawer body 310. A handle 321 may be provided on the drawer door 320 for easy pulling out of the drawer.

[0093] In some embodiments, the drawer door 320 may be located within the storage compartment 101. For example, the drawer 300 may be installed in a refrigerator compartment, the opening of which is provided with a rotatable door 200.

[0094] In other embodiments, the drawer door 320 may be exposed outside the storage compartment 101. For example, the drawer body 310 may be pull-out mounted in a freezer compartment or a variable temperature compartment.

[0095] When drawer 300 is closed, drawer door 320 abuts against the front side of cabinet 100. The edge of drawer door 320 may be provided with a door seal to improve the sealing of storage compartment 101.

[0096] An insulation layer is also provided inside the drawer door 320 to improve its insulation performance.

[0097] In this embodiment, the drawer 300 is slidably connected to the storage compartment 101, allowing the drawer 300 to be pulled outward through the opening of the storage compartment 101. The sliding connection structure between the drawer and the storage compartment 101 is described in detail below with reference to the accompanying drawings.

[0098] Continue to refer to Figure 2 Drawer 300 is connected to the cabinet 100 via guide rail assembly 400, so that drawer 300 can move along the depth direction of storage compartment 101 (corresponding to...). Figure 2 Pull out along the Y-axis.

[0099] In this embodiment of the application, the cabinet 100 includes a section along the width direction of the storage compartment 101 (corresponding to...). Figure 2 The storage compartment 101 is located between two compartment side walls that are opposite and spaced apart in the X-axis direction.

[0100] The drawer 300 includes drawer sidewalls 311 that are spaced apart and opposite to each other along the width of the storage compartment 101.

[0101] Drawer 300 also includes a drawer bottom wall 313, which is connected to the bottom of the two drawer side walls 311. The bottom surface of the drawer bottom wall 313 may be provided with reinforcing ribs to improve the drawer's support strength.

[0102] Drawer 300 may also include a drawer rear wall 312, which is fixed to the rear end of the drawer bottom wall 313 and the two drawer side walls 311.

[0103] Drawer 300 may also include a front wall, which is opposite to and spaced from the rear wall 312 along the depth of the storage compartment 101. A drawer door 320 is fixed to the front side of the front wall. In some implementations, the drawer door 320 may be used to form the front wall.

[0104] With the above configuration, the drawer body 310 is enclosed by a front wall, a rear wall 312, a bottom wall 313, and two side walls 311 to form an upward-opening storage cavity 301.

[0105] For example, the drawer body 310 is a one-piece molded component, which helps to ensure the structural strength of the drawer 300 and the relative sealing of the storage cavity 301.

[0106] The storage cabinet in this embodiment of the application is provided with two guide rail assemblies 400. Each guide rail assembly 400 is respectively disposed between a compartment side wall and a drawer side wall 311. Thus, along the width direction of the storage compartment 101, the drawers are respectively connected to the compartment side walls through the guide rail assemblies 400, ensuring the stability of the drawer pulling out.

[0107] Reference Figure 2 and Figure 3 In some embodiments of this application, the guide rail assembly 400 includes a first guide rail 410, which is fixed to the side wall of the compartment. Exemplarily, the first guide rail 410 can be fixed to the side wall of the compartment with screws, resulting in structural stability. Exemplarily, the first guide rail 410 is integrally formed into the side wall of the compartment, which helps to ensure the integrity of the storage compartment 101. The first guide rail 410 extends along the depth direction of the storage compartment 101 (corresponding to...). Figure 2 (Extends along the Y-axis).

[0108] The guide rail assembly 400 may further include a second guide rail 420, which is fixed to the drawer side wall 311. Exemplarily, the first guide rail 410 can be fixed to the drawer side wall 311 by screws, resulting in a stable structure. Exemplarily, the first guide rail 410 is integrally formed into the drawer side wall 311, which helps to ensure the integrity of the storage cavity 301.

[0109] The second guide rail 420 runs along the depth direction of the storage compartment 101 (corresponding to...). Figure 2 The second guide rail 420 extends along the Y-axis and is slidably connected to the first guide rail 410.

[0110] In this embodiment, a second guide rail 420 is fixed on the drawer side wall 311, and a first guide rail 410 is fixed on the compartment side wall. The first guide rail 410 and the second guide rail 420 are slidably connected to realize the push and pull of the drawer 300 relative to the storage compartment 101.

[0111] The first guide rail 410 has a front end that faces the opening of the storage compartment 101. An elastic connector 500 is provided at the front end of the first guide rail 410, and one end of the elastic connector 500 facing away from the first guide rail 410 is fixedly connected to the second guide rail 420. It can be understood that the elastic connector 500 has two opposite ends along the depth direction of the storage compartment 101, and both ends of the elastic connector 500 are respectively connected to the first guide rail 410 and the second guide rail 420, with the elastic connector 500 located on the front side of the first guide rail 410.

[0112] The elastic connector 500 is configured to elastically deform along the extension direction of the first guide rail 410 when the drawer 300 is pulled outward, thereby pulling the drawer 300 backward, increasing the resistance to pulling the drawer 300 outward, and preventing the drawer 300 from being opened arbitrarily.

[0113] In some embodiments, when the drawer 300 is in the closed position, the elastic connector 500 is in a stretched state, so that the elastic connector 500 generates a rearward stretching force on the drawer 300, making the closing of the drawer 300 more reliable.

[0114] In other embodiments, when the drawer 300 is in the closed position, the resilient connector 500 is in its natural state. This reduces the resistance when the drawer 300 is pulled out, preventing excessive resistance that could affect ease of use. Furthermore, it avoids fatigue damage to the resilient connector 500 from being constantly deformed. Here, the natural state of the resilient connector 500 refers to its free state without elastic deformation.

[0115] In this embodiment, at least one first guide rail 410 is provided with an elastic locking component 600 at its front end, and the second guide rail 420 is provided with a mating hole 421 at its rear end. When the drawer 300 pulls the second guide rail 420 outward until the mating hole 421 engages with the elastic locking component 600, the drawer 300 is locked in the open position, thereby ensuring that the drawer 300 stops in the open position, which facilitates the retrieval and placement of items in the storage cavity 301.

[0116] When drawer 300 needs to be closed, the elastic locking component 600 is operated to disengage from the mating hole 421. Under the elastic force of the elastic connector 500, drawer 300 can be automatically closed. The closing operation of drawer 300 is simple, quick, and effortless.

[0117] In some embodiments, a resilient locking component 600 is provided at the front end of one of the first guide rails 410. This configuration allows the resilient locking component 600 to be operated with one hand, and the drawer 300 to be pulled with one hand, thus preventing the drawer 300 from pinching the hand after the locking component loses its locking effect and causing safety problems.

[0118] In other embodiments, the front ends of the two first guide rails 410 are respectively provided with elastic locking components 600, and the rear ends of the two second guide rails 420 are respectively provided with mating holes 421. This arrangement allows the left and right sides of the drawer 300 to be locked by the elastic locking components 600, which not only improves the reliability of the locking action but also improves the uniformity of force distribution on the drawer 300.

[0119] When it is necessary to unlock drawer 300, both elastic locking components 600 need to be operated with both hands. Since the elastic connector 500 is in its natural state when drawer 300 is in the closed position, the gripping force of drawer 300 on the hands is negligible when unlocking elastic locking components 600.

[0120] To prevent hands from being caught in the closed drawer 300, in some possible implementations, the resilient locking assembly 600 is provided with an intermediate transmission structure so that the operating part of the resilient locking assembly 600 is located on the outside of the drawer 300, so that the operating part is exposed on the outside of the drawer 300 when the drawer 300 is closed, making it easy to operate.

[0121] When drawer 300 is installed in the refrigerator compartment, the front end of the first guide rail 410 can be exposed in the refrigerator compartment, making it easy to unlock drawer 300 through the elastic locking component 600, which is simple and convenient to operate.

[0122] In some applications, the user applies a pushing force to the drawer 300, causing the elastic locking component 600 to disengage from the mating hole 421, thereby unlocking the drawer 300 and ensuring safe operation.

[0123] In some possible implementations of this application, a mating hole 421 is provided at the rear end of the second guide rail 420. The elastic locking component 600 engages with this mating hole 421 to restrict the outward extension position of the drawer 300, facilitating the retrieval and placement of items. The mating hole 421, located at the rear end of the second guide rail 420, allows the drawer 300 to extend outwards by a greater distance, facilitating the retrieval and placement of items.

[0124] In some other possible implementations of this application, the second guide rail 420 is provided with a plurality of mating holes 421, which are arranged at intervals along the extension direction of the second guide rail 420. This allows the drawer 300 to have multiple locking positions when pulled outward, making it convenient for the user to stop the drawer 300 in a suitable position according to actual needs.

[0125] The drawer 300 can be unlocked by using the pushing or pulling force applied by the user to the drawer 300, which causes the elastic locking component 600 to disengage from the mating hole 421.

[0126] With the above configuration, the storage cabinet of this embodiment has a drawer 300 that can be pulled out of the storage compartment 101; the drawer sidewall 311 and the compartment sidewall are connected by a guide rail assembly 400. The guide rail assembly 400 includes a first guide rail 410 fixed to the compartment sidewall and a second guide rail 420 fixed to the drawer sidewall 311. The second guide rail 420 is slidably connected to the first guide rail 410, so that the drawer 300 can be pulled out and moved relative to the storage compartment 101. An elastic connector 500 is provided between the front end of the first guide rail 410 and the second guide rail 420. The elastic connector 500 is configured to elastically deform along the extension direction of the second guide rail 420 when pulled outward, thereby pulling the drawer 300 backward, increasing the resistance to pulling the drawer 300 outward, reducing the chance of the drawer 300 being opened at will, especially by children, and improving the safety of the drawer 300. Furthermore, when drawer 300 is closed, the first elastic element 530 returns to its original shape, causing drawer 300 to move backward into storage compartment 101, making the closing operation of drawer 300 easier. Additionally, by providing an elastic locking component 600 at the front end of the first guide rail 410, when drawer 300 is pulled outward, the elastic locking component 600 can engage with the mating hole 421 provided on the second guide rail 420, locking drawer 300 and keeping it in the open position for easy access to items.

[0127] Reference Figure 4 In some embodiments of this application, a plurality of elastic connectors 500 are provided on the first guide rail 410, and the plurality of elastic connectors 500 are arranged at intervals along the height direction of the first guide rail 410.

[0128] For example, the first guide rail 410 is connected to two elastic connectors 500, which are arranged at intervals along the height direction of the first guide rail 410.

[0129] In this way, by setting multiple elastic connectors 500, the resistance to pulling the drawer 300 outward is ensured, preventing the drawer 300 from being opened at will; and the elastic force for the drawer 300 to automatically return to its original position is also ensured.

[0130] Reference Figure 5 In some embodiments, the elastic connector 500 includes a connecting sleeve 510, one end of which is fixedly connected to the first guide rail 410; the connecting sleeve 510 extends along the extending direction of the first guide rail 410. The connecting sleeve 510 has a hollow structure.

[0131] The elastic connector 500 may further include a connecting rod 520, one end of which is slidably mounted within the connecting sleeve 510; the other end of which is fixedly connected to the second guide rail 420. To reduce the weight of the elastic connector 500, the connecting rod 520 may be a hollow structure.

[0132] Reference Figure 6 A second connecting plate 521 is provided at the end of the connecting rod 520 away from the connecting sleeve 510. The second connecting plate 521 is connected to the second guide rail 420 by screws, which improves the reliability and stability of the connection between the connecting rod 520 and the second guide rail 420.

[0133] The elastic connector 500 may further include a first elastic element 530, which is sleeved on the outside of the connecting rod 520, and one end of the first elastic element 530 is fixedly connected to the connecting sleeve 510, and the other end of the first elastic element 530 is fixedly connected to the connecting rod 520; the first elastic element 530 is configured to elastically deform along the extension direction of the first guide rail 410.

[0134] exist Figure 5 The illustration uses a spring as an example of the first elastic element 530, but this is not a limitation on the first elastic element 530. For example, the first elastic element 530 can also be an elastic sleeve, etc.

[0135] When the drawer 300 is pulled outward, the connecting rod 520 drives the first elastic element 530 to stretch, thereby causing the first elastic element 530 to deform, increasing the resistance of the drawer 300 to be pulled outward, and reducing the possibility of the drawer 300 being opened at will.

[0136] An annular gap is formed between the connecting rod 520 and the connecting sleeve 510 to accommodate the first elastic member 530. Thus, when the drawer 300 is closed, at least a portion of the first elastic member 530 retracts into the annular gap between the connecting rod 520 and the connecting sleeve 510.

[0137] In this embodiment, the elastic connector 500 is connected to the first guide rail 410 via a connecting sleeve 510 and to the second guide rail 420 via a connecting rod 520. The connecting rod 520 and the connecting sleeve 510 are slidably connected, providing space for the elastic deformation of the first elastic member 530. Furthermore, the cooperation between the connecting rod 520 and the connecting sleeve 510 provides guidance for the elastic deformation direction of the first elastic member 530. The first elastic member 530 also increases the resistance when the drawer 300 is pulled outward, reducing the possibility of the drawer 300 being opened arbitrarily. Moreover, the first elastic member 530 can also assist in closing the drawer 300, making the closing of the drawer 300 faster and easier.

[0138] Reference Figure 4 and Figure 7 In some embodiments of this application, the front end of the first guide rail 410 is provided with a mounting hole 411, and the mounting hole 411 is along the height direction of the drawer 300 (corresponding to...). Figure 7 Extending in the Z-axis direction. Mounting hole 411 provides a mounting position for resilient locking assembly 600.

[0139] The resilient locking assembly 600 includes a second resilient member 610 having two opposing ends along its deformation direction. One end of the second resilient member 610 is fixed within a mounting hole 411, and the other end of the second resilient member 610 extends to the top outside the mounting hole 411. The second resilient member 610 is configured to elastically deform along the axial direction of the mounting hole 411.

[0140] exist Figure 7 In the illustration, the second elastic element 610 is shown as a spring, but this is not a limitation on the second elastic element 610. For example, the second elastic element 610 can also be an elastic component 720, etc.

[0141] The resilient locking assembly 600 may further include a locking head 620, which is fixedly connected to the other end of the second resilient member 610. The locking head 620 is configured to engage with a mating hole 421 when facing each other along the height direction of the drawer 300 to lock the drawer 300 in the open position.

[0142] In some embodiments, the top surface of the locking head 620 can be an arc-shaped surface. For example, the top of the locking head 620 is a hemispherical structure that extends into the mating hole 421. This configuration facilitates the locking head 620 to engage with or disengage from the mating hole 421, thereby allowing the locking head 620 to disengage from the mating hole 421 using the pushing or pulling force of the drawer 300, thus releasing the locking limitation on the drawer 300.

[0143] When the elastic locking component 600 is not aligned with the mating hole 421, the elastic locking component 600 is subjected to the pressure of the first guide rail 410, causing the elastic locking component 600 to retract into the mounting hole 411; when the elastic locking component 600 is aligned with the mating hole 421, the second elastic element 610 restores its deformation, driving the locking head 620 into the mating hole 421, thereby achieving the locking and limiting of the drawer 300.

[0144] Of course, in some possible implementations, the elastic locking assembly 600 may also include a telescopic rod structure, with the two ends of the second elastic member 610 connected to the inner rod and outer rod of the telescopic rod structure respectively, and the second elastic member 610 sleeved on the outside of the telescopic rod structure. The telescopic rod structure can extend and retract, providing elastic deformation space for the second elastic member 610; the telescopic rod structure can also provide guidance for the elastic deformation direction of the second elastic member 610.

[0145] With the above settings, the elastic locking assembly 600, by setting the second elastic element 610 to elastically deform along the height direction of the drawer 300, drives the locking head 620 to compress or extend along the height direction of the drawer 300, thereby enabling the locking head 620 to be engaged in or disengaged from the mating hole 421, thereby achieving locking and unlocking of the drawer 300.

[0146] Continue to refer to Figure 8 In some embodiments of this application, the second guide rail 420 is configured to form a groove 422, which extends along the depth direction of the storage compartment 101 and opens towards the side of the first guide rail 410; along the height direction of the box 100 (corresponding to Figure 8 In the Z-axis direction, the size of the groove 422 is larger than the size of the opening of the groove 422.

[0147] The second guide rail 420 may include a first groove wall 423 which may be arranged parallel to the side wall of the compartment. The first groove wall 423 may also be connected to a mounting plate 428, which is used to fix the drawer side wall 311.

[0148] The second guide rail 420 may further include two second groove walls 424, which are respectively connected to the first groove wall 423 on both sides along the height direction, and the two second groove walls 424 are located on the side of the first groove wall 423 away from the drawer 300. Along the height direction of the cabinet 100, the interval between the two second groove walls 424 is the size of the slide 422.

[0149] The second guide rail 420 may further include two limiting groove walls 425, each limiting groove wall 425 being connected to a second groove wall 424, and the limiting groove wall 425 and the first groove wall 423 being along the width direction of the housing 100 (corresponding to...). Figure 8 The chain's respective limiting groove walls 425 are spaced apart along the height direction of the housing 100 to form openings in the slide grooves 422.

[0150] A portion of the first guide rail 410 is inserted into the slide groove 422 so that the first guide rail 410 slides relative to the second guide rail 420.

[0151] By providing a groove 422 with an opening on one side in the second guide rail 420, a portion of the first guide rail 410 can be inserted into the groove for sliding, enabling relative sliding between the first guide rail 410 and the second guide rail 420. This also ensures that the first guide rail 410 and the second guide rail 420 are limited in the width direction, preventing them from separating in the width direction.

[0152] Combination Figure 7The first guide rail 410 includes a fixing part 412, which is fixed to the side wall of the compartment. For example, the fixing part 412 is fixed to the side wall of the compartment by screws, and the connection method is stable and reliable.

[0153] The first guide rail 410 may also include a sliding part 413, which is slidably mounted on the slide groove 422.

[0154] The first guide rail 410 may further include a connecting part 414, which connects the fixing part 412 and the sliding part 413, and the connecting part 414 passes through the opening of the slide groove 422. Along the height direction of the drawer 300 (corresponding to...) Figure 7 In the Z-axis direction, the size of the connecting part 414 is smaller than that of the sliding part 413, so that the connecting part 414 can pass through the opening of the slide groove 422; the size of the fixing part 412 is larger than that of the sliding part 413, so that the fixing part 412 has sufficient space to be fixedly connected to the side wall of the compartment.

[0155] The elastic connector 500 is connected to the front end of the sliding part 413, and the mounting hole 411 is provided at the top of the sliding part 413, so that the elastic locking component 600 is provided at the top of the front end of the sliding part 413.

[0156] Therefore, the first guide rail 410 of this application embodiment is fixedly connected to the side wall of the compartment by setting a fixing part 412, slidably installed in the slide groove 422 by setting a sliding part 413, and connected by a connecting part 414. The structure is simple and easy to implement.

[0157] Of course, the above is only a schematic illustration of the structure of the first guide rail 410 and the second guide rail 420. The first guide rail 410 and the second guide rail 420 can also be dovetail groove guide rails, guide rails with ball bearings, etc.

[0158] Continue to refer to Figure 8 In some embodiments of this application, the second guide rail 420 is fixed with a first connecting block 426, which is located at the front end of the slide groove 422.

[0159] The other end of the elastic connector 500 is fixedly connected to the first connecting block 426.

[0160] By setting a first connecting block 426 in the groove 422 of the second guide rail 420, and connecting the first connecting block 426 with the elastic connector 500, the elastic connector 500 and the second guide rail 420 are fixedly connected. The structure is simple and easy to implement.

[0161] In some possible implementations, the first connecting block 426 slides relative to the slide groove 422. A second connecting block 427 is fixed within the slide groove 422, located behind the first connecting block 426. The second connecting block 427 has a through hole so that the end of the connecting rod 520 facing away from the connecting sleeve 510 passes through the through hole and connects with the first connecting block 426. When the drawer 300 is pulled outward, the drawer 300 drives the second guide rail 420 and the second connecting block 427 to move forward. Under the constraint of the second connecting block 427, the first connecting block 426 moves forward, thereby causing the elastic connector 500 to stretch and deform.

[0162] Reference Figure 9 In some embodiments of this application, an elastic buffer assembly 700 is provided between the drawer rear wall 312 of the drawer 300 and the compartment rear wall of the storage compartment 101.

[0163] By setting the elastic buffer component 700, the drawer rear wall 312 and the compartment rear wall are in elastic contact, which buffers the force when the drawer 300 is closed. This can reduce the expansion force between the drawer 300 and the compartment rear wall, and also reduce collision noise.

[0164] Reference Figure 9 and Figure 10 In some possible implementations, the resilient cushioning assembly 700 includes: a connecting plate 710 fixed to the outside of the drawer rear wall 312; the connecting plate 710 extends along the width direction of the drawer 300.

[0165] The elastic buffer assembly 700 may further include a plurality of elastic members 720, which are spaced apart along the extension direction of the connecting plate 710. Each elastic member 720 has two opposite ends along its elastic deformation direction, one end of which is fixedly connected to the connecting plate 710, and the other end of which is used to elastically abut against the rear wall of the compartment.

[0166] The elastic buffer assembly 700 of this application improves the reliability of elastic buffering of drawer 300 by setting multiple elastic components 720 to form multiple elastic buffer positions.

[0167] In some embodiments, the elastic component 720 can be an elastic rubber head, which has a simple structure and is easy to implement.

[0168] In other embodiments, the elastic component 720 includes a first connecting plate 721, which is fixedly connected to the connecting plate 710. For example, the first connecting plate 721 and the connecting plate 710 are fixedly connected by screws, providing a stable and reliable connection.

[0169] The elastic member 720 may further include a third elastic member 722, which is configured to move along the pull-out direction of the drawer 300 (corresponding to...). Figure 9 Elastic deformation (in the Y-axis direction). Figure 9 and Figure 10 In the example shown, the third elastic element 722 is a spring, but this is not a limitation on the third elastic element 722. For example, the third elastic element 722 can be an elastic sleeve, etc.

[0170] The third elastic member 722 is configured to elastically deform along the pull-out direction of the drawer 300, and the third elastic member 722 has two opposite ends along its elastic deformation direction, one end of the third elastic member 722 being fixedly connected to the first connecting plate 721.

[0171] The resilient member 720 may also include an abutment 723, which is fixedly connected to the other end of the third resilient member 722; the abutment 723 is configured to abut against the rear wall of the compartment.

[0172] In some embodiments, the surface of the abutment 723 facing the rear wall of the compartment can be an arc-shaped surface to reduce the contact area between the abutment 723 and the rear wall of the compartment. Exemplarily, the abutment 723 can be hemispherical, which has a simple structure and is easy to implement.

[0173] In this embodiment, the elastic component 720 is fixedly connected to the connecting plate 710 by a first connecting plate 721, abuts against the rear wall of the compartment by an abutment 723, and connects the first connecting plate 721 and the abutment 723 by a third elastic component 722, so that the abutment 723 elastically abuts against the rear wall of the compartment.

[0174] In some possible implementations of this application, the elastic member 720 may further include an inner post 724 and an outer cylinder 725, both extending along the drawer 300's pull-out direction. The inner post 724 is inserted into the outer cylinder 725, and the inner post 724 can be slidably connected relative to the outer cylinder 725, allowing the total length of the inner post 724 and the outer cylinder 725 to extend or retract.

[0175] The first connecting plate 721 is connected to the end of the outer cylinder 725 away from the inner column 724, and the abutment 723 is connected to the end of the inner column 724 away from the outer cylinder 725. The third elastic member 722 is sleeved on the outside of the inner column 724 and the outer cylinder 725, and the two ends of the third elastic member 722 abut against the abutment 723 and the first connecting plate 721 respectively.

[0176] Thus, the elastic component 720 provides guidance for the elastic deformation direction of the third elastic component 722 by setting the inner column 724 and the outer cylinder 725, thereby improving the elastic buffering effect of the elastic component 720 on the drawer 300.
