For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0070] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0071] The embodiment of the present application provides a storage rack, which can be used to place objects, including but not limited to food, accessories, kitchen supplies or medical supplies, that is, the storage rack can be used in the fields of medical care, furniture, kitchenware or office supplies, and the embodiment of the present application does not specifically limit the use of the storage rack.

[0072] like Figure 1 As shown, the storage rack at least includes a first body 1 and a second body 2, a connecting rod 3, a first stopper 4 and a second stopper 5 distributed along its height direction. Figure 2 As shown, the connecting rod 3 includes a first end 31 and a second end 32, the first end 31 is rotatably connected to the first body 1, and the second end 32 is rotatably connected to the second body 2, and along the height direction of the rack, the second body 2 can move toward or away from the first body 1; the first limiting member 4 is installed on the first body 1, and the first end 31 is provided with a first limiting matching portion, and the first limiting member 4 can abut against the first limiting matching portion to limit the rotation of the connecting rod 3 relative to the first body 1; as shown in FIG. Figure 3 and Figure 4 As shown, the second limiting member 5 is installed on the second body 2 , and the second end 32 is provided with a second limiting fitting portion 321 . The second limiting member 5 can abut against the second limiting fitting portion 321 to limit the rotation of the connecting rod 3 relative to the second body 2 .

[0073] In this embodiment, a first body 1 and a second body 2 are arranged distributed along the height direction thereof, so that the rack has multiple layers of accommodation space in the height direction, thereby improving the utilization rate of the space in the height direction of the rack, and further improving the storage capacity of the rack; the first body 1 and the second body 2 are connected by a connecting rod 3, and the connecting rod 3 is rotatably connected to the first body 1 and the second body 2 respectively, so that the distance and angle between the first body 1 and the second body 2 can be adjusted, such as Figure 5 As shown in FIG. 1 , when the distance between the first body 1 and the second body 2 in the height direction is reduced, the overall height of the rack can be reduced, thereby facilitating the transportation and storage of the rack. Figure 6As shown, when the angle between the first body 1 and the second body 2 is adjusted, the rack can meet different usage requirements, thereby improving the working performance of the rack and improving the user experience; the first limit member 4 and the first limit matching portion, the second limit member 5 and the second limit matching portion 321 are used to limit the rotation of the connecting rod 3, thereby improving the stability of the rack in a certain state. For example, when the rack is in a state such as Figure 2 In the use state shown, the stability of the distance and angle between the first body 1 and the second body 2 can be improved, and the risk of the second body 2 moving or turning over under the action of gravity or external force is reduced, thereby improving the safety of the storage rack.

[0074] like Fig. 9 As shown, the first limiting member 4 includes a first limiting body 41 and a first limiting portion 42, the first limiting portion 42 can abut against the first limiting matching portion, the first limiting body 41 is connected to the first body 1 through a first rotating shaft 43, and the storage rack also includes a first elastic member 44, the first elastic member 44 is connected to the first limiting body 41, and the first elastic member 44 can drive the first limiting body 41 to swing around the first rotating shaft 43; Figure 3 and Figure 4 As shown, the second limiting member 5 includes a second limiting body 51 and a second limiting portion 52, the second limiting portion 52 can abut against the second limiting matching portion 321, the second limiting body 51 is connected to the second body 2 through a second rotating shaft 53, and the storage rack also includes a second elastic member, the second elastic member is connected to the second limiting body 51, and the second elastic member can drive the second limiting body 51 to swing around the second rotating shaft 53.

[0075] In this embodiment, the first limiting member 4 is installed on the first body 1 through the first rotating shaft 43, so that the first limiting member 4 can swing around the first rotating shaft 43, so as to facilitate the release of the abutment and cooperation between the first limiting member 4 and the first limiting matching portion, thereby releasing the limiting effect of the first limiting member 4 on the connecting rod 3. When the connecting rod 3 rotates relative to the first body 1 by a preset angle, the first elastic member 44 can drive the first limiting member 4 to automatically reset, so that the first limiting member 4 automatically abuts and cooperates with the first limiting matching portion, thereby simplifying the user's operation and reducing the difficulty of operating the rack; The second limiting member 5 is installed on the second body 2 via the second rotating shaft 53, so that the second limiting member 5 can swing around the second rotating shaft 53, thereby facilitating the release of the abutment between the second limiting member 5 and the second limiting matching portion 321, thereby releasing the limiting effect of the second limiting member 5 on the connecting rod 3; when the connecting rod 3 rotates by a preset angle relative to the second body 2, the second elastic member can drive the second limiting member 5 to automatically reset, so that the second limiting member 5 automatically abuts against the second limiting matching portion 321, thereby simplifying the user's operation and further reducing the difficulty of operating the storage rack.

[0076] Among them, the first rotating shaft 43 is a fastener such as a screw or a bolt, that is, the first rotating shaft 43 is threadedly connected to the first body 1 to simplify the connection method between the first rotating shaft 43 and the first body 1, reduce the installation cost of the first rotating shaft 43, and help to simplify the structure of the first body 1, reducing the processing cost of the first body 1; the second rotating shaft 53 is a fastener such as a screw or a bolt, that is, the second rotating shaft 53 is threadedly connected to the second body 2 to simplify the connection method between the second rotating shaft 53 and the second body 2, reduce the installation cost of the second rotating shaft 53, and help to simplify the structure of the second body 2, reducing the processing cost of the second body 2.

[0077] Specifically, the first elastic member 44 is a torsion spring, such as Figure 6 and Fig.10 As shown, the first body 1 is provided with a first mounting groove 411, the first limiting body 41 is provided with a second mounting groove 11, one end of the first elastic member 44 is located in the first mounting groove 411, and the other end is located in the second mounting groove 11; similarly, the second elastic member is a torsion spring, the second body 2 is provided in the third mounting groove, the second limiting body 51 is provided with a fourth mounting groove, one end of the second elastic member is located in the third mounting groove, and the other end is located in the fourth mounting groove.

[0078] In this embodiment, the first elastic member 44 and the second elastic member are configured as torsion springs, which can be sleeved on the first rotating shaft 43 and the second rotating shaft 53, thereby simplifying the installation method and installation structure of the first elastic member 44 and the second elastic member, thereby reducing the installation cost of the first elastic member 44 and the second elastic member.

[0079] like Figure 3 , Figure 5 and Figure 6 As shown, when the first body 1 is placed on a desktop, the ground or other platforms, the first body 1 cannot rotate. After the connecting rod 3 rotates to a preset angle, the first limiting member 4 abuts against the first limiting matching portion on the first end 31. At this time, the first end 31 achieves balance under the action of its own gravity, the rotational force at the first end 31, and the abutment force between the first limiting member 4 and the first limiting matching portion, so that the first end 31 is limited at a preset angle.

[0080] like Figure 3 and Figure 4 As shown, the storage rack further includes a stop member 6 , which is mounted on the second body 2 . The stop member 6 can abut against the second limiting member 5 to limit the swing of the second limiting member 5 around the second rotation axis 53 .

[0081] In this embodiment, the second limiter 5 abuts against the stopper 6, and the stopper 6 can limit the second limiter 5 from swinging in the direction away from the second limiter matching portion 321, so that the second limiter 5 and the second limiter matching portion 321 remain in abutment state, reducing the second limiter 5 and the second limiter matching portion 321 from being released during use, thereby improving the working stability and use safety of the rack. In addition, after the connecting rod 3 rotates to a preset angle, the second limiter 5 abuts against the second limiter matching portion 321 of the second end 32, and at the same time, the second limiter 5 abuts against the stopper 6. At this time, the second end 32 achieves balance under the action of its own weight, the rotation force at the second end 32, the ground contact force between the second limiter 5 and the second limiter matching portion 321, and the contact force between the second limiter 5 and the stopper 6, so that the second end 32 is limited at a preset angle, and then the second body 2 is limited at a preset height and a preset angle, so as to further improve the working stability and use safety of the rack.

[0082] like Figure 6 , Fig.11 and Fig.12 As shown, the second body 2 is provided with a slide groove 21 , and the stop member 6 is installed in the slide groove 21 . Along the extension direction of the slide groove 21 , the stop member 6 can move relative to the second body 2 to release the restriction on the swing of the second limiting member 5 .

[0083] In this embodiment, driving the stop member 6 to slide along the slide groove 21 can release the abutment between the stop member 6 and the second limiting member 5 to destroy the force balance at the second end 32, thereby facilitating the adjustment of the height and angle of the second body 2, thereby reducing the difficulty of operating the rack.

[0084] Along the width direction of the chute 21, Fig.11 and Fig.12 As shown, a limiting groove 61 is provided on one or both sides of the stop member 6, and a clamping portion 211 is provided on the side wall of the slide groove 21. At least a portion of the clamping portion 211 is located in the limiting groove 61, and along the width direction of the limiting groove 61, at least a portion of the clamping portion 211 abuts against the side wall of the limiting groove 61.

[0085] In this embodiment, the clamping portion 211 abuts against the side wall of the limiting groove 61, and along the depth direction of the slide groove 21, the risk of the stop member 6 detaching from the slide groove 21 through the opening of the slide groove 21 is reduced, thereby improving the connection stability between the stop member 6 and the slide groove 21, and further facilitating improving the working stability and reliability of the stop member 6.

[0086] In any of the above embodiments, Fig. 9As shown, the first position-limiting member 4 is provided with a first abutting surface 421, and the first position-limiting matching portion is provided with a second abutting surface. The first abutting surface 421 abuts against the second abutting surface, and the first abutting surface 421 and / or the second abutting surface are arc surfaces; Figure 4 As shown, the second limiting member 5 is provided with a third abutting surface, and the second limiting matching portion 321 is provided with a fourth abutting surface 321a, the third abutting surface abuts against the fourth abutting surface 321a, and the third abutting surface and / or the fourth abutting surface 321a are arc surfaces.

[0087] In this embodiment, the first abutment surface 421 and / or the second abutment surface are arc surfaces. When the first abutment surface 421 abuts against the second abutment surface, the contact area between the first abutment surface 421 and the second abutment surface is increased, thereby reducing the risk of damage to the first abutment surface 421 and the second abutment surface due to local large force. At the same time, when the second abutment surface is an arc surface, during the rotation of the first end 31, the first limit member 4 can move along the second abutment surface, so that the first limit member 4 swings around the first rotation axis 43 under the drive of the first limit matching portion until the first limit member 4 is released from the abutment with the first limit matching portion. Therefore, the second abutment surface is an arc surface, which increases the smoothness of the movement of the first limit member 4 during the rotation of the first end 31. Similarly, the third abutting surface and / or the fourth abutting surface 321a is an arc surface. When the third abutting surface abuts the fourth abutting surface 321a, the contact area between the third abutting surface and the fourth abutting surface 321a is increased, thereby reducing the risk of damage to the third abutting surface and the fourth abutting surface 321a due to local large force. At the same time, when the fourth abutting surface 321a is an arc surface, during the rotation of the second end 32, the second limit member 5 can move along the fourth abutting surface 321a, so that the second limit member 5 swings around the second rotating shaft 53 under the drive of the second limit fitting portion 321 until the second limit member 5 is released from the abutment with the second limit fitting portion 321. Therefore, the fourth abutting surface 321a is an arc surface, which increases the smoothness of the movement of the second limit member 5 during the rotation of the second end 32.

[0088] In any of the above embodiments, the first position-limiting fitting portion is a groove, the number of the first position-limiting fitting portion is one, or at least two first position-limiting fitting portions are distributed along the circumference of the first end 31; and / or, as Figure 4 As shown, the second position limiting fitting portion 321 is a groove, and the number of the second position limiting fitting portion 321 is one, or at least two second position limiting fitting portions 321 are distributed along the circumference of the second end 32 .

[0089] In this embodiment, when the number of the first position limiting fitting portion and the second position limiting fitting portion 321 is one, the processing cost of the connecting rod 3 is reduced, thereby reducing the overall cost of the rack; when the number of the first position limiting fitting portion and the second position limiting fitting portion 321 is multiple, the diversity of the angles between the connecting rod 3 and the first body 1 and the second body 2 when the rack is in use is increased, thereby increasing the diversity of the setting height and setting angle of the second body 2 to improve the performance of the rack.

[0090] Among them, when the number of the first limiting fitting parts is multiple, during the rotation of the first end 31, the first limiting member 4 moves along the second abutting surface, so that the first limiting portion 42 swings in the direction away from the first end 31 until the first limiting portion 42 is released from the abutment with the first limiting fitting part. At this time, the first limiting portion 42 is suspended above the groove. At the same time, driven by the rebound force of the first elastic member 44, the first limiting portion 42 swings in the direction close to the first end 31, so that the first limiting portion 42 abuts against the adjacent first limiting fitting part. When the connecting rod 3 stops swinging, the first end 31 is limited and fixed under the action of the gravity of the connecting rod 3, the torsional force of the first end 31 and the abutting force of the first limiting member 4; when the number of the second limiting fitting parts 321 is multiple, during the rotation of the second end 32 During the process, the second limiting member 5 moves along the fourth abutment surface 321a, so that the second limiting portion 52 swings in the direction away from the second end 32 until the second limiting portion 52 releases the abutment with the second limiting matching portion 321. At this time, the second limiting portion 52 is suspended above the groove. At the same time, driven by the rebound force of the second elastic member, the second limiting portion 52 swings in the direction close to the second end 32, so that the second limiting portion 52 abuts against the adjacent second limiting matching portion 321. When the connecting rod 3 stops swinging, the stop member 6 is moved to the top of the second limiting member 5 to abut against the second limiting member 5. The second end 32 is limited and fixed under the action of the gravity of the connecting rod 3, the torsional force of the second end 32, the abutment force between the first limiting member 4 and the second end 32, and the abutment force between the first limiting member 4 and the stop member 6.

[0091] In any of the above embodiments, Fig. 9 As shown, the first position-limiting member 4 is provided with a first operating portion 45, and the first operating portion 45 is located on a side of the first position-limiting member 4 away from the first end 31; and / or, as Figure 4 As shown, the second position-limiting member 5 is provided with a second operating portion 54 , and the second operating portion 54 is located at a side of the second position-limiting member 5 away from the second end 32 .

[0092] In this embodiment, the user can drive the first limit member 4 to swing around the first rotation axis 43 through the first operating part 45, so that the first limit member 4 is released from the abutment with the first limit matching part. When the first end 31 rotates to a preset angle, the user cancels the force applied to the first operating part 45, and the first limit member 4 is automatically reset and abutted with the first limit matching part under the drive of the first elastic member 44, so that the first end 31 is limited and fixed. Similarly, the user can drive the second limit member 5 to swing around the second rotation axis 53 through the second operating part 54, so that the second limit member 5 is released from the abutment with the second limit matching part 321. When the second end 32 rotates to a preset angle, the user cancels the force applied to the second operating part 54, and the second limit member 5 is automatically reset and abutted with the second limit matching part 321 under the drive of the second elastic member, so that the second end 32 is limited and fixed. The first operating part 45 and the second operating part 54 are provided to increase the contact area between the user and the first limiting member 4 and the second limiting member 5, thereby simplifying the operation of the user driving the first operating member and the second operating member to rotate, thereby reducing the difficulty of operating the storage rack.

[0093] Among them, along the length direction of the first limit member 4, the first operating part 45 and the first limit member 42 are relatively arranged on both sides of the first limit body 41. When the operator applies a force on the first operating part 45, the operator's torque is increased, thereby reducing the force applied by the operator on the first operating part 45, so that the operator can drive the first limit member 4 to rotate; along the length direction of the second limit member 5, the second operating part 54 and the second limit member 52 are relatively arranged on both sides of the second limit body 51. When the operator applies a force on the second operating part 54, the operator's torque is increased, thereby reducing the force applied by the operator on the second operating part 54, so that the operator can drive the second limit member 5 to rotate.

[0094] In any of the above embodiments, the number of connecting rods 3 is one to simplify the structure of the rack and reduce the material cost and installation cost of the rack; or, the number of connecting rods 3 is at least two, and multiple connecting rods 3 are distributed along the length direction of the rack, and / or, multiple connecting rods 3 are distributed along the width direction of the rack, and / or, the connecting rods 3 are cross-distributed in an X shape to improve the stability of the second body 2 during the lifting and rotation process, and is beneficial to improving the overall structural strength of the rack to extend the service life of the rack.

[0095] In any of the above embodiments, Figure 2As shown, a shaft sleeve 7 is embedded in the first body 1 and the second body 2, a threaded hole is provided in the shaft sleeve 7, a fastener 9 is threadedly connected and fixed to the shaft sleeve 7, and the first end 31 and the second end 32 are respectively sleeved on the fastener 9 to realize the connection between the connecting rod 3 and the first body 1 and the second body 2, thereby simplifying the connection method between the connecting rod 3 and the first body 1 and the second body 2, which is beneficial to reducing the installation cost and difficulty of the storage rack.

[0096] Among them, Figure 7 and Figure 8 As shown, the first end 31 and the second end 32 extend along the thickness direction of the connecting rod 3 to increase the structural strength at the first end 31 and the second end 32 , thereby facilitating prolonging the service life of the connecting rod 3 .
