Description

Technical Field

[0001] This application relates to the field of warehouse racking technology, and more specifically to a drawer-type racking system. Background Technology

[0002] Shelving is an indispensable piece of equipment in warehousing and logistics. Its main function is to store and manage various goods, thereby improving the utilization of warehouse space and the efficiency of goods access. Traditional shelving designs are relatively simple, typically consisting of uprights, beams, and shelves, and are mainly used for storing small, lightweight goods. However, this traditional shelving makes it difficult to achieve quick and convenient access when dealing with large, heavy, or oddly shaped goods, seriously affecting the efficiency and flexibility of warehouse management. To solve these problems, drawer-type shelving has emerged. Drawer-type shelving uses movable pallets or drawer frames on the main frame of the shelving, equipped with rails, rollers, and other auxiliary devices, allowing goods to be easily pulled out and pushed back in like drawers, greatly improving the convenience and efficiency of goods access.

[0003] For example, Chinese utility model patent CN209720630U discloses a drawer-type shelf, including a base frame and a shelf. The base frame is provided with multiple pairs of C-shaped guide rails distributed along the height of the base frame. Each pair of guide rails consists of two rails, located on opposite inner walls of the base frame. The shelf corresponds one-to-one with each pair of guide rails. One end of the shelf is rotatably connected to rollers located inside the guide rails on both opposite side walls. A guide wheel for supporting the other end of the shelf is rotatably provided on the inner wall of the base frame. Each of the two opposite guide rails is connected to a limit block by fastening screws at the end near the guide wheel. A limit plate is rotatably connected to the side wall of the base frame above the guide rails. The end of the limit plate away from the base frame is provided with a V-shaped locking plate. Fixing plates are provided on both opposite side walls of the shelf. The fixing plates have limit grooves at the end near the rollers. In this technical solution, when goods need to be retrieved or placed, the operator pulls the shelf out of the base frame, and then pushes it back into the base frame after retrieval or placement, which improves the convenience of goods storage and retrieval to some extent. However, after the shelf is pulled out of the base frame, one end of it only contacts the guide rail through rollers, while the other end is suspended in the air. The stress point of the shelf is concentrated on one end, which can easily lead to uneven stress. Especially when the goods are heavy, the shelf cannot withstand much pressure with only the guide wheels and rollers at one end for support, thus limiting the load-bearing capacity of the rack. On the other hand, the shelf is partially suspended after being pulled out of the base frame, which may affect its stability. Especially when the goods are not placed evenly, the shelf is prone to tilting or even tipping over, posing a safety hazard. Summary of the Invention

[0004] The technical problem to be solved by this application is to provide a drawer-type shelf, which provides support through the cooperation of a first slide rail and a second slide rail after the drawer is pulled out, so that the auxiliary upright can cooperate with the support frame to support heavier goods, thus improving its practicality.

[0005] This application provides a drawer-type shelf, including a support frame and drawers. The support frame has a multi-layered storage cavity, and a first slide rail is provided in each storage cavity. The drawer is equipped with multiple rollers, and the rollers are connected to the first slide rail to allow the drawer to slide within the storage cavity. The shelf also includes an auxiliary upright. A hinge structure is installed between the support frame and the auxiliary upright. The auxiliary upright rotates through the hinge structure to open and close the storage cavity. The auxiliary upright is equipped with a second slide rail adapted to the first slide rail. The first and second slide rails cooperate to allow the drawer to slide and extend / retract. When the drawer slides out of the storage cavity, at least one roller remains connected to the first slide rail.

[0006] In this technical solution, the support frame is equipped with a multi-layered storage cavity, and each storage cavity is provided with a first slide rail, so that a drawer is slidably installed in each storage cavity. The drawer is connected to the first slide rail through rollers to improve sliding efficiency. By adding an auxiliary upright to the support frame, the auxiliary upright is connected to the support frame through a hinge structure, so that the auxiliary upright can rotate freely relative to the support frame within a certain angle range. When the drawer is needed, the auxiliary upright can be rotated and unfolded through the hinge structure, so that the storage cavity is opened and the drawer can slide out from the storage cavity. When the drawer is pushed back into the storage cavity or is not needed, the auxiliary upright can be rotated and closed through the hinge structure, so that the storage cavity is closed, reducing the storage space occupied by the auxiliary upright, saving space in the warehouse or storage area, and making space utilization more efficient. Users can easily unfold or close the auxiliary upright as needed to adapt to different storage and retrieval needs.

[0007] A second slide rail is installed on the auxiliary upright. This second slide rail, when the auxiliary upright rotates and unfolds, works with the first slide rail to form a longer track, providing extended support for the drawer. This allows the drawer to slide smoothly out of the storage cavity. When the drawer is extended, the unfolded auxiliary upright provides additional support. The cooperation between the first and second slide rails makes the drawer more stable during sliding and extension, facilitating stable loading and unloading of goods. When the drawer slides out of the storage cavity, at least one roller remains connected to the first slide rail, ensuring that the drawer's weight is borne simultaneously by the support frame and the auxiliary upright, preventing the entire drawer from sliding onto the auxiliary upright and avoiding deformation of the auxiliary upright due to sole load-bearing. The hinged structure and the cooperation of the first and second slide rails enhance the shelf's load-bearing capacity, allowing for the storage of heavier goods. It also improves the shelf's stability, reducing the risk of goods slipping or the shelf tipping over due to improper operation, resulting in improved practicality.

[0008] As an improvement, the hinge structure includes a first hinge member, a second hinge member, and a pivot. The first hinge member is mounted on the support frame, and the second hinge member is mounted on the auxiliary upright. The first and second hinge members are rotatably connected by the pivot. In this technical solution, the hinge structure consists of a first hinge member, a second hinge member, and a pivot. The first and second hinge members are rotatably connected by the pivot. The first hinge member is fixed to the support frame, and the second hinge member is fixed to the auxiliary upright, allowing the auxiliary upright to rotate relative to the support frame, thus enabling opening and closing. Through the hinge structure, the auxiliary upright shares the weight with the support frame when unfolded, allowing the rack to store heavier goods and improving the load-bearing capacity of the entire racking system. The hinge structure also has a certain degree of shock resistance, absorbing and dispersing the force caused by goods movement or external impacts to a certain extent, protecting the rack structure from damage, and enhancing the overall stability of the rack.

[0009] As an improvement, the first hinge member is provided with multiple layers of first connecting plates, and the second hinge member is provided with multiple layers of second connecting plates. The first and second connecting plates are sequentially interlocked and rotatably connected by a pivot. In this technical solution, multiple connecting plates are provided on both the first and second hinge members, which increases the stability and strength of the hinge structure and can better support and transmit torque. The sequential interlocking of the first and second connecting plates improves the tightness and reliability of the connection between the first and second hinge members, ensuring the stability of the hinge structure during rotation. The design of multiple first and second connecting plates improves the load-bearing capacity of the hinge structure, allowing the auxiliary upright to share the weight of the drawer with the support frame when unfolded, reducing the risk of shelf deformation or damage due to load. The interlocking design of the first and second connecting plates can better distribute and bear the weight of the drawer, improving the load-bearing performance of the entire shelving system.

[0010] As an improvement, the second hinge is provided with a third connecting plate that connects to the auxiliary upright. The second hinge has an L-shaped structure. In this technical solution, the second hinge consists of a second connecting plate and a third connecting plate. The second connecting plate is used to rotatably connect to the first connecting plate of the first hinge, and the third connecting plate is used to connect to the auxiliary upright, ensuring stability under load. The second hinge can simultaneously undertake the functions of connection and support. The L-shaped structure of the second and third connecting plates saves installation space on the auxiliary upright, making the rack design more compact. The L-shaped structure of the second hinge simplifies the installation process, making the installation of the auxiliary upright faster and more convenient. The L-shaped structure of the second hinge provides a more stable support point, which helps to improve the load-bearing capacity of the auxiliary upright.

[0011] As an improvement, two drawers are symmetrically installed horizontally within the storage cavity, and auxiliary uprights are rotatably installed on both sides of the support frame. In this technical solution, two drawers are installed in each storage cavity, symmetrically distributed horizontally, allowing for drawer pull-out operations from both sides of the shelf, increasing its flexibility. The auxiliary uprights rotatably installed on both sides of the support frame ensure effective support for the drawers on both sides during use. The double-sided drawer design allows for more comprehensive utilization of storage space, improving space efficiency and allowing simultaneous operation from both sides. This significantly improves the efficiency of goods storage and retrieval, especially in situations requiring rapid access. Furthermore, the symmetrical installation of the drawers helps maintain the balance of the shelf structure, preventing tilting or deformation caused by unilateral load-bearing.

[0012] As an improvement, a first baffle is installed inside the storage cavity, located between the two drawers. The first baffle limits the range of the drawers' sliding retraction. In this technical solution, the first baffle between the two drawers serves to separate and position them, limiting the range of the drawers' sliding retraction and preventing one drawer from sliding excessively, thus preventing the other drawer from fully retracting into the storage cavity. Furthermore, the first baffle ensures that the drawers remain in an easily accessible position when needed, improving reliability and ease of operation.

[0013] As an improvement, a second baffle is provided at the end of the second slide rail furthest from the first slide rail. This second baffle limits the range of the drawer's sliding extension. In this technical solution, the second baffle at the end of the second slide rail limits the maximum distance the drawer can slide out, increasing the stability of the drawer during sliding and preventing goods from falling or the drawer from being damaged due to excessive pulling out. The limited sliding range of the drawer makes operation more controllable, allowing users to more precisely control the drawer's position and improving operational convenience. By limiting the drawer's sliding range, the stability of the drawer during sliding is enhanced, making the shelf structure more robust, suitable for storing various types of goods, and improving safety during use.

[0014] As an improvement, a support block adapted to the first slide rail is provided inside the storage cavity. The support block is connected to the first slide rail to support it. In this technical solution, the support block added inside the storage cavity mainly supports the first slide rail, preventing it from deforming or shifting due to load. This allows the first slide rail to better bear the weight of the drawer and its contents, improving the load-bearing capacity of the shelf. The connection between the support block and the first slide rail enhances the structural stability of the entire drawer system, making the drawers more stable when pulled out and pushed back, thus improving the safety and service life of the entire shelf.

[0015] As an improvement, an elastic positioning element is installed between the support frame and the auxiliary upright. When the auxiliary upright rotates to open the storage cavity, the support frame and the auxiliary upright abut against each other through the elastic positioning element. In this technical solution, the auxiliary upright opens and closes the storage cavity by rotating. The elastic positioning element installed between the support frame and the auxiliary upright allows for stable positioning and support when the auxiliary upright rotates to a preset position. When the auxiliary upright rotates to open the storage cavity, the auxiliary upright and the support frame abut against each other through the elastic positioning element, enhancing the stability of the auxiliary upright in the open state. The elastic positioning element can also absorb the impact force generated by the weight of the goods or during operation, reducing the direct contact between the support frame and the auxiliary upright, thereby reducing wear and extending the service life of the shelf.

[0016] As an improvement, the auxiliary stand is equipped with a second crossbar for gripping. The second slide rail is located on the inner side of the auxiliary stand, and the second crossbar is located on the outer side of the auxiliary stand, with the second crossbar and the second slide rail spaced apart. In this technical solution, the second crossbar on the auxiliary stand is specifically designed for the operator's grip, allowing the operator to easily rotate the auxiliary stand and open and close the storage cavity, improving operational convenience. The spaced arrangement of the second slide rail and the second crossbar avoids interference between the second slide rail and the user's grip on the second crossbar, improving operational comfort and convenience.

[0017] As an improvement, the drawer is equipped with at least two handles; the handles are rotatably mounted on the drawer. In this technical solution, at least two handles on the drawer provide multiple gripping points for the operator, allowing the operator to pull the drawer with both hands, enhancing the effortlessness of drawer operation. The handles are rotatably mounted on the drawer, adapting to different users' operating habits, providing a more comfortable grip, and reducing fatigue during operation. Furthermore, the handles can be rotated and retracted, avoiding interference with the rotation and closure of the auxiliary support frame, resulting in a more compact overall structure and saving installation space.

[0028] like Figures 1 to 5 As shown, this application discloses a drawer-type shelf, including a support frame 1 and drawers 2. The support frame 1 has a multi-layered storage cavity 11, and a first slide rail 12 is provided in each storage cavity 11. Multiple rollers 21 are installed on the drawers 2, and the rollers 21 are connected to the first slide rail 12 to allow the drawers 2 to slide within the storage cavity 11. The support frame 1 has a multi-layered storage cavity 11, and each storage cavity 11 is provided with a first slide rail 12, so that a drawer 2 is slidably installed in each storage cavity 11. The drawers 2 are connected to the first slide rail 12 via rollers 21 to improve sliding efficiency. An auxiliary upright 3 is added to the support frame 1, and a hinge structure 4 is installed between the support frame 1 and the auxiliary upright 3. The storage cavity 11 can be opened and closed by rotating the hinge structure 4, allowing the auxiliary stand 3 to rotate freely within a certain angle range relative to the support frame 1. When the drawer 2 is needed, the auxiliary stand 3 can be rotated and unfolded through the hinge structure 4, allowing the storage cavity 11 to be opened and the drawer 2 to slide out from the storage cavity 11. When the drawer 2 is pushed back into the storage cavity 11 or is not needed, the auxiliary stand 3 can be rotated and closed through the hinge structure 4, allowing the storage cavity 11 to be closed, reducing the storage space occupied by the auxiliary stand 3, saving space in the warehouse or storage area, and making space utilization more efficient. Users can easily unfold or close the auxiliary stand 3 as needed to adapt to different storage and retrieval needs.

[0029] like Figure 1 and Figure 3As shown, the auxiliary support 3 is equipped with a second slide rail 31 that matches the first slide rail 12. The first slide rail 12 and the second slide rail 31 cooperate to allow the drawer 2 to slide and extend. When the auxiliary support 3 is rotated and unfolded, the second slide rail 31 cooperates with the first slide rail 12 to form a longer track. The second slide rail 31 provides an extended support for the drawer 2, allowing the drawer 2 to slide smoothly out of the storage cavity 11. When the drawer 2 is extended for use, the unfolding of the auxiliary support 3 provides additional support for the drawer 2. Through the cooperation of the first slide rail 12 and the second slide rail 31, the drawer 2 can slide and extend more smoothly. The design enhances stability, facilitating stable loading and unloading of goods. When drawer 2 slides out of storage cavity 11, at least one roller 21 remains connected to the first slide rail 12, ensuring that the weight of drawer 2 is simultaneously borne by support frame 1 and auxiliary upright 3. This prevents the entire drawer 2 from sliding onto the auxiliary upright 3, thus avoiding deformation of the auxiliary upright 3 due to bearing the weight alone. The hinge structure 4, the cooperation of the first slide rail 12 and the second slide rail 31 enhance the load-bearing capacity of the shelf, allowing for the storage of heavier goods. It also improves the stability of the shelf, reducing the risk of goods slipping or the shelf tipping over due to improper operation, resulting in better practicality.

[0030] More specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, the hinge structure 4 includes a first hinge 41, a second hinge 42, and a pivot 43. The first hinge 41 is mounted on the support frame 1, and the second hinge 42 is mounted on the auxiliary upright 3. The first hinge 41 and the second hinge 42 are rotatably connected by the pivot 43. The hinge structure 4 is composed of the first hinge 41, the second hinge 42, and the pivot 43. The first hinge 41 and the second hinge 42 are rotatably connected by the pivot 43. The first hinge 41 is fixed to the support frame 1, and the second hinge 42 is fixed to the auxiliary upright 3, allowing the auxiliary upright 3 to rotate relative to the support frame 1, thus achieving opening and closing actions. Through the hinge structure 4, the auxiliary upright 3 shares the weight with the support frame 1 when unfolded, enabling the rack to store heavier goods and improving the load-bearing capacity of the entire rack system. The hinge structure 4 also has a certain degree of shock resistance, absorbing and dispersing the force caused by goods movement or external impacts to a certain extent, protecting the rack structure from damage, and enhancing the overall stability of the rack.

[0031] More specifically, such as Figure 2As shown, the first hinge 41 is provided with multiple layers of first connecting plates 411, and the second hinge 42 is provided with multiple layers of second connecting plates 421. The first connecting plates 411 and the second connecting plates 421 are sequentially interlocked and rotatably connected by a pivot 43. The multiple layers of connecting plates on both the first hinge 41 and the second hinge 42 increase the stability and strength of the hinge structure 4, enabling better support and torque transmission. The sequential interlocking of the first connecting plates 411 and the second connecting plates 421 improves the tightness and reliability of the connection between the first hinge 41 and the second hinge 42, ensuring the stability of the hinge structure 4 during rotation. The design of multiple layers of first connecting plates 411 and second connecting plates 421 improves the load-bearing capacity of the hinge structure 4, allowing the auxiliary upright 3 to share the weight of the drawer 2 with the support frame 1 when unfolded, reducing the risk of shelf deformation or damage due to load. The interlocking design of the first connecting plates 411 and the second connecting plates 421 can better distribute and bear the weight of the drawer 2, improving the load-bearing performance of the entire shelving system.

[0032] More specifically, such as Figure 2 and Figure 5 As shown, the second hinge 42 is provided with a third connecting plate 422 that connects to the auxiliary upright 3. The second hinge 42 has an L-shaped structure and is composed of a second connecting plate 421 and a third connecting plate 422. The second connecting plate 421 is used to rotatably connect to the first connecting plate 411 of the first hinge 41, and the third connecting plate 422 is used to connect to the auxiliary upright 3 to ensure stability under load. The second hinge 42 can simultaneously undertake the functions of connection and support. The second connecting plate 421 and the third connecting plate 422 are joined to form an L-shaped structure, which saves installation space on the auxiliary upright 3 and makes the rack design more compact. The L-shaped structure of the second hinge 42 simplifies the installation process, making the installation of the auxiliary upright 3 faster and more convenient. The L-shaped structure of the second hinge 42 provides a more stable support point, which is beneficial to improving the load-bearing performance of the auxiliary upright 3.

[0033] More specifically, such as Figure 1As shown, two drawers 2 are symmetrically installed horizontally in the storage cavity 11. Auxiliary uprights 3 are rotatably installed on both sides of the support frame 1. Two drawers 2 are installed in each layer of the storage cavity 11. The two drawers 2 are symmetrically distributed horizontally, so that the drawers 2 can be pulled out from both sides of the shelf, which increases the flexibility of the shelf. The auxiliary uprights 3 are rotatably installed on both sides of the support frame 1 to ensure that the drawers 2 on both sides can be effectively supported by the auxiliary uprights 3 when in use. The double-sided drawer 2 design allows the shelf to make more comprehensive use of the storage space, improves the space utilization rate, and allows simultaneous operation from both sides. This can significantly improve the efficiency of goods storage and retrieval, especially when goods need to be stored and retrieved quickly. In addition, the symmetrical installation of the drawers 2 helps to maintain the balance of the shelf structure and avoid the shelf tilting or deformation caused by unilateral load-bearing.

[0034] More specifically, such as Figure 1 As shown, a first baffle 13 is installed inside the storage cavity 11. The first baffle 13 is located between the two drawers 2. The first baffle 13 is used to limit the sliding and retracting range of the drawers 2. The first baffle 13 is set between the two drawers 2. The first baffle 13 plays a role in separating and positioning. It can limit the range of the drawers 2 when sliding and retracting, and prevent one drawer 2 from sliding and retracting too much, causing the other drawer 2 to not be able to retract completely into the storage cavity 11. Furthermore, the first baffle 13 can ensure that the drawers 2 are kept in an easily accessible position when needed, improving the reliability and ease of use.

[0035] More specifically, such as Figure 4 As shown, a second baffle 32 is provided at the end of the second slide rail 31 away from the first slide rail 12. The second baffle 32 is used to limit the range of the drawer 2's sliding extension. The second baffle 32 at the end of the second slide rail 31 limits the maximum distance the drawer 2 can slide, increasing the stability of the drawer 2 when sliding and preventing goods from falling or the drawer 2 from being damaged due to excessive pulling out. The sliding range of the drawer 2 makes the operation more controllable, allowing users to control the position of the drawer 2 more precisely and improving the convenience of operation. By limiting the sliding range of the drawer 2, the stability of the drawer 2 when sliding is enhanced, making the shelf structure more stable, suitable for storing various types of goods, and improving the safety of use.

[0036] More specifically, such as Figure 4As shown, a support block 14 adapted to the first slide rail 12 is provided in the storage cavity 11. The support block 14 is connected to the first slide rail 12 to support the first slide rail 12. The main function of the support block 14 in the storage cavity 11 is to support the first slide rail 12 and prevent the first slide rail 12 from deforming or shifting due to load. This allows the first slide rail 12 to better bear the weight of the drawer 2 and its contents, improving the load-bearing capacity of the shelf. The connection between the support block 14 and the first slide rail 12 enhances the structural stability of the entire drawer 2 system, making the drawer 2 more stable when pulled out and pushed back, thus improving the safety and service life of the entire shelf.

[0037] More specifically, such as Figure 5 As shown, an elastic positioning element 5 is installed between the support frame 1 and the auxiliary upright 3. When the auxiliary upright 3 rotates to open the storage cavity 11, the support frame 1 and the auxiliary upright 3 abut against each other through the elastic positioning element 5. The auxiliary upright 3 opens and closes the storage cavity 11 by rotating. The elastic positioning element 5 installed between the support frame 1 and the auxiliary upright 3 allows for stable positioning and support when the auxiliary upright 3 rotates to a preset position. When the auxiliary upright 3 rotates to open the storage cavity 11, the auxiliary upright 3 abuts against the support frame 1 through the elastic positioning element 5, which enhances the stability of the auxiliary upright 3 in the open state. The elastic positioning element 5 can also absorb the impact force generated by the weight of the goods or during operation, reducing the direct contact between the support frame 1 and the auxiliary upright 3, thereby reducing wear and extending the service life of the shelf.

[0038] More specifically, such as Figure 1 As shown, the auxiliary support frame 3 is provided with a second crossbar 33 for gripping. The second slide rail 31 is located on the inner side of the auxiliary support frame 3, and the second crossbar 33 is located on the outer side of the auxiliary support frame 3. The second crossbar 33 and the second slide rail 31 are spaced apart. The second crossbar 33 on the auxiliary support frame 3 is specifically designed for the operator to grip, allowing the operator to easily rotate the auxiliary support frame 3 and open and close the storage cavity 11, thus improving the convenience of operation. The spaced arrangement of the second slide rail 31 and the second crossbar 33 avoids interference between the second slide rail 31 and the user's grip on the second crossbar 33, improving the comfort and convenience of operation.

[0039] More specifically, such as Figure 1 As shown, drawer 2 is provided with at least two handles 22. The handles 22 are rotatably mounted on drawer 2. The presence of at least two handles 22 on drawer 2 provides multiple grip points for the operator, allowing the operator to pull drawer 2 with both hands, thus enhancing the effortlessness of operating drawer 2. The handles 22 are rotatably mounted on drawer 2, which can adapt to the operating habits of different users, providing a more comfortable grip and reducing fatigue during operation. On the other hand, the handles 22 can be rotated and retracted to avoid interfering with the rotation and closure of the auxiliary support frame 3. The overall structure is more compact and saves more installation space.

[0040] This application is not limited to the above-described preferred embodiments. Anyone can derive other products in various forms under the guidance of this application. However, regardless of any changes made to their shape or structure, any technical solution that is the same as or similar to that of this application falls within the protection scope of this application.
