Description

Technical Field

[0001] This utility model relates to the field of warehouse racking technology, specifically a warehouse racking with an anti-tipping structure. Background Technology

[0002] In the field of modern warehousing and logistics, mobile storage racks are widely used because of their mobility, which allows for flexible adjustment of warehouse layout and improvement of space utilization. Traditional mobile storage racks usually use self-locking wheels to move and fix the racks. When the rack position needs to be adjusted, the self-locking wheels can be unlocked to push the rack to move. After reaching the designated position, the self-locking wheels can be locked to fix the rack.

[0003] However, since the self-locking wheel only contacts the ground through a simple braking structure, when a large number of goods are stored on the shelf, factors such as uneven weight distribution of goods, external impact during storage and retrieval, or uneven warehouse floor may cause the self-locking wheel to fail to provide sufficient friction to maintain the stability of the shelf, which may cause the shelf to tilt or even tip over. In order to solve the above problems, the inventors have proposed a storage rack with an anti-tipping structure. Utility Model Content

[0004] To address the issue of poor stability in traditional mobile shelving systems, the purpose of this invention is to provide a storage rack with an anti-tipping structure.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a storage rack with an anti-tipping structure, comprising a storage rack body, wherein the bottom ends of the legs of the storage rack body are rotatably connected to self-locking wheels, and one side of each leg of the storage rack body is rotatably connected to a support leg, with corresponding two support legs symmetrically distributed. An adjustment component is provided at the bottom of the storage rack body and between corresponding two legs, the adjustment component being used to adjust the unfolding or retraction of the corresponding support leg, and a support plate is rotatably connected to the end of each support leg away from the storage rack body.

[0006] Preferably, the adjusting assembly includes two fixed plates, which are fixedly connected between the bottoms of the two storage rack bodies. A threaded rod is rotatably connected between the two fixed plates. A movable plate is threadedly connected to the outer side of the threaded rod. Support rods are rotatably connected to both ends of the movable plate. The end of each support rod away from the movable plate is rotatably connected to a corresponding support leg. A guide rod is provided on one side of each support leg of the storage rack body. An installation groove is fixedly connected inside each guide rod. The two ends of the movable plate are slidably engaged between the two corresponding installation grooves. The top of each threaded rod extends to the top of the storage rack body and is fixedly connected to a throttle handle. A synchronous pulley is fixedly connected to the outer side of the top of each threaded rod. A synchronous belt is connected between the outer sides of the two storage rack bodies for transmission.

[0007] Preferably, the length of the support rod is greater than the distance from the end of the support rod connecting to the support leg to the rotation axis of the support leg.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] By turning the throttle, the threaded rod and synchronous pulley are driven to rotate. The two synchronous pulleys are connected by a synchronous belt, which in turn drives the two threaded rods to rotate. This causes the moving plate to move vertically along the outer side of the threaded rods. The support rods connect and simultaneously push the corresponding two support legs to rotate symmetrically vertically. The two support legs can be adjusted to open and close. When the warehouse rack body is needed, the support legs are retracted to facilitate the movement of the rack. Once the rack is moved to the appropriate position, the support legs are extended to improve the stability of the warehouse rack body when placed, thus preventing the rack body from tipping over.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-4 As shown, this utility model provides a storage rack with an anti-tipping structure, including a storage rack body 1. The bottom ends of the legs of the storage rack body 1 are rotatably connected to self-locking wheels 2. One side of each leg of the storage rack body 1 is rotatably connected to a support leg 3. The two corresponding support legs 3 are symmetrically distributed. An adjustment component is provided at the bottom end of the storage rack body 1 and between the two corresponding legs. The adjustment component is used to adjust the unfolding or retraction of the corresponding support leg 3.

[0018] The adjustment assembly includes two fixed plates 4, which are fixedly connected between the bottoms of the two storage rack bodies 1. A threaded rod 5 is rotatably connected between the two fixed plates 4. A movable plate 6 is threadedly connected to the outer side of the threaded rod 5. Support rods 7 are rotatably connected to both ends of the movable plate 6. The end of the support rod 7 away from the movable plate 6 is rotatably connected to the corresponding support leg 3.

[0019] By adopting the above technical solution, rotating the threaded rod 5 drives the moving plate 6 to move vertically along the outside of the threaded rod 5, and drives the end of the support rod 7 connected to the moving plate 6 to move vertically. The support leg 3 guides the bottom end of the support rod 7, thereby simultaneously pushing the two corresponding support legs 3 to rotate symmetrically vertically, thereby adjusting the opening and closing of the two support legs 3.

[0020] Guide rods 8 are provided on one side of each leg of the storage rack body 1. Each guide rod 8 has a mounting groove 9 fixedly connected inside. The two ends of the movable plate 6 are slidably engaged between the corresponding two mounting grooves 9.

[0021] By adopting the above technical solution and setting the mounting groove 9, the vertical movement of the movable plate 6 can be guided, thereby improving the stability of the movable plate 6 during vertical movement.

[0022] Each of the support legs 3, at the end furthest from the storage rack body 1, is rotatably connected to a support plate 10.

[0023] By adopting the above technical solution and setting the support plate 10, the support area between the bottom of the support leg 3 and the ground can be increased, thereby improving the stability of the support leg 3 when it is supported.

[0024] The top of each threaded rod 5 extends above the storage rack body 1 and is fixedly connected to a throttle 13. A synchronous pulley 11 is fixedly connected to the outer side of the top of each threaded rod 5. A synchronous belt 12 is connected between the outer sides of the two storage rack bodies 1 for transmission.

[0025] By adopting the above technical solution and setting the throttle 13, it is easier to rotate and adjust the threaded rod 5. When the threaded rod 5 rotates, it drives the synchronous wheel 11 to rotate. The two synchronous wheels 11 are connected by a synchronous belt 12, which drives the two threaded rods 5 to rotate at the same time, so as to realize the synchronous rotation adjustment between the support legs 3.

[0026] The length of the support rod 7 is greater than the distance from the end of the support rod 7 connected to the support leg 3 to the rotation axis of the support leg 3.

[0027] By adopting the above technical solution, and by setting the length of the support rod 7 to be greater than the distance from the end of the support rod 7 to the rotation axis of the support leg 3, the support leg 3 can rotate stably under the push of the support rod 7.

[0028] Working Principle: When using this mobile storage rack, when it is necessary to move the rack, the support legs 3 are retracted to facilitate the movement of the rack body 1. When the rack body 1 is moved to a suitable position and its position needs to be fixed, the throttle 13 on one side is turned to drive the threaded rod 5 and the synchronous wheel 11 to rotate. The two synchronous wheels 11 are connected by a synchronous belt 12, which drives the two threaded rods 5 to rotate. The mounting groove 9 guides the vertical movement of the moving plate 6, thereby driving the two moving plates 6 to move downward synchronously along the outer side of the corresponding threaded rod 5. This also drives the end of the support rod 7 connected to the moving plate 6 to move downward. The support legs 3 guide the bottom end of the support rod 7, thereby simultaneously pushing the support legs 3 and the support plate 10 to rotate downward, so that the support plate 10 contacts the ground. The cooperation between the support legs 3 and the support rod 7 supports the rack body 1, preventing it from tipping over and further improving the stability of the rack body 1 when placed.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
