Description

Technical Field

[0001] This utility model relates to the technical field of item storage devices, specifically a storage rack that is easy to adjust in height. Background Technology

[0002] Storage racks are support structures used to store goods or items, typically consisting of multiple shelves and uprights. They are widely used in industrial, commercial, and warehousing fields, playing a vital role in improving storage efficiency and reducing space occupancy.

[0003] Nowadays, storage racks are widely used in warehouses and express delivery stations. Storage racks in different locations are classified according to the size of the express packages. However, the spacing between multiple shelves on existing storage racks is fixed and difficult to adjust. When storing small packages, they are stacked in large quantities, which makes them very easy to collapse during use. Therefore, we have launched a storage rack that is easy to adjust in height. Utility Model Content

[0004] The purpose of this utility model is to provide a storage rack that is easy to adjust in height, allowing for quick and individual adjustment of the height of multiple storage shelves, resulting in high adjustment efficiency and reducing the user's workload, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A storage rack with adjustable height includes a top plate, with support legs fixed at the four corners of the bottom of the top plate. Multiple storage plates are arranged between the support legs, and the corners of the multiple storage plates are slidably connected to the four support legs. Strip plates are fixed on both sides of the bottom of the top plate, and each of the multiple storage plates has a strip hole that mates with the strip plate. A cavity is provided inside the storage plate, and a through hole is provided between the strip hole and the cavity. A rotating shaft is rotatably provided in the middle of the cavity through a rolling bearing, and a locking mechanism that can lock with the strip plate is provided inside the cavity.

[0007] Furthermore, the locking mechanism includes a locking rod, which is slidably disposed within the through hole. The strip plate has multiple locking grooves that cooperate with the locking rod. Connecting rods are hinged to both sides of one end of the locking rod located within the cavity. A sliding rod is hinged to the other end of the connecting rod. A fixing block is slidably disposed on the wall of the sliding rod. The fixing block is fixedly connected to the cavity. A circular block is fixedly connected to the end of the sliding rod away from the locking rod. A spring is movably sleeved on the wall of the sliding rod between the fixing block and the circular block. A steel wire rope is fixedly disposed between the locking rod and the rotating shaft.

[0008] Furthermore, the diameter of the circular block is larger than the diameter of the spring.

[0009] Furthermore, the spring is always in a compressed state.

[0010] Furthermore, the lower end of the rotating shaft extends through the storage plate and is fixedly equipped with a handwheel.

[0011] Furthermore, the handwheel sidewall is provided with multiple anti-slip protrusions.

[0012] Furthermore, the locking rod has a chamfer at one end located outside the cavity.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This height-adjustable storage rack features support legs, a top plate, strip plates, storage plates, a handwheel, a wire rope, a connecting rod, a fixing block, a circular block, a sliding rod, a spring, a locking rod, and a rotating shaft. To adjust the height of the storage plates, turn the handwheel. The handwheel drives the rotating shaft, and the wire rope, wound around the shaft, moves two locking rods. The locking rods, through the connecting rod, move the sliding rod, which in turn moves the circular block to compress the spring. When the locking rod moves outside the locking slot, the height of the storage plate can be adjusted. After adjustment, release the handwheel. The spring pushes the circular block, which, through the sliding rod, pulls the connecting rod. The two connecting rods then engage the locking rod in the corresponding locking slot. This allows for quick and individual height adjustment of multiple storage plates, offering high efficiency and reducing the user's workload. Attached Figure Description

[0020] 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.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution:

[0022] A storage rack with adjustable height includes a top plate 2. Support legs 1 are fixed at the four corners of the bottom of the top plate 2. The bottom of the support legs 1 is provided with anti-slip sleeves. Multiple storage plates 4 are arranged between the support legs 1. The corners of the multiple storage plates 4 are slidably connected to the four support legs 1 respectively. Strip plates 3 are fixed on both sides of the bottom of the top plate 2. Each of the multiple storage plates 4 is provided with strip holes that cooperate with the strip plates 3. A cavity is provided inside the storage plate 4. A through hole is provided between the strip holes and the cavity. A rotating shaft 13 is rotatably provided in the middle of the cavity through a rolling bearing. The lower end of the rotating shaft 13 extends through to the outside of the storage plate 4 and is fixedly provided with a handwheel 5. The handwheel 5 allows the user to rotate the rotating shaft 13. Multiple anti-slip protrusions are provided on the side wall of the handwheel 5 to increase the anti-slip properties of the side wall of the handwheel 5. A locking mechanism that can lock with the strip plates 3 is provided in the cavity.

[0023] The locking mechanism includes a locking rod 12, which is slidably disposed in the through hole. The strip plate 3 has multiple locking grooves that cooperate with the locking rod 12. Connecting rods 7 are hinged to both sides of one end of the locking rod 12 located in the cavity. A sliding rod 10 is hinged to the other end of the connecting rod 7. A fixing block 8 is slidably disposed on the wall of the sliding rod 10 and is fixedly connected to the cavity. A circular block 9 is fixedly connected to the end of the sliding rod 10 away from the locking rod 12. A spring 11 is movably sleeved on the wall of the sliding rod 10 between the fixing block 8 and the circular block 9. The spring 11 is always in a compressed state. A steel wire rope 6 is fixedly disposed between the locking rod 12 and the rotating shaft 13. A chamfer is provided at the end of the locking rod 12 located outside the cavity. The chamfer facilitates the locking rod 12 to be inserted into the locking groove. The diameter of the circular block 9 is larger than the diameter of the spring 11, which ensures that the circular block 9 pushes the spring 11.

[0024] When the height of the storage plate 4 needs to be adjusted, turn the handwheel 5. The handwheel 5 drives the rotating shaft 13 to rotate. While the wire rope 6 is wound around the rotating shaft 13, it drives the two locking rods 12 to move. The locking rods 12 drive the slide rod 10 to slide through the connecting rod 7. The slide rod 10 drives the circular block 9 to compress the spring 11. When the locking rod 12 moves to the outside of the locking groove, the height of the storage plate 4 can be adjusted. After the height of the storage plate 4 is adjusted, release the handwheel 5. The spring 11 pushes the circular block 9. The circular block 9 pulls the connecting rod 7 through the slide rod 10. The two connecting rods 7 drive the locking rod 12 to lock into the corresponding locking groove. The height of multiple storage plates 4 can be quickly adjusted individually, which is highly efficient and reduces the labor intensity of the user.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
