DETAILED DESCRIPTION
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the accompanying drawings in the embodiments of the utility model, so as to have a further understanding of the concept of the utility model, the technical problems solved, the technical features constituting the technical solutions and the technical effects brought about.
[0022] like Figure 1 As shown, an adjustable shelf for storage includes a supporting base plate 2, a top cover 1 and a plurality of vertical supporting columns 3, the supporting columns 3 connecting the supporting base plate 2 and the top cover 1, a shelf plate 4 is arranged between the supporting base plate 2 and the top cover 1, and the shelf plate 4 is slidably connected to the supporting columns 3; a lifting top plate 5 is installed on the shelf plate 4, a sleeve 8 is installed on the supporting base plate 2, a vertically arranged screw rod 6 is installed in the sleeve 8, the upper end of the screw rod 6 is threadedly connected to the lifting top plate 5, and the lower end of the screw rod 6 is installed with a horizontally arranged first bevel gear 11; a rotating shaft 9 is installed through the side surface of the sleeve 8, and a vertically arranged second bevel gear 12 is installed on one end of the rotating shaft 9 located in the sleeve 8, and the second bevel gear 12 is meshed with the first bevel gear 11.
[0023] When storing goods on shelves, different types of goods are constantly stored, and the sizes and weights of the goods are different. Currently, shelves are pre-designed with different placement spaces, including shelves for large goods and shelves for ordinary goods. However, in actual storage, there may be insufficient corresponding shelves or shelves for ordinary goods may be idle because they cannot hold large goods.
[0024] like Figure 2 , Figure 3As shown, the shelf board 4 of the utility model is slidably connected to the support column 3, and the height of the shelf board 4 can be adjusted at will, and then the space between the support bottom plate 2 and the top cover 1 is divided into placement areas of different heights by using the change in the height of the shelf board 4. The height adjustment of the shelf board 4 and the support after adjustment are completed by the screw rod 6, the first bevel gear 11, the second bevel gear 12 and the rotating shaft 9. The upper end of the screw rod 6 is threadedly connected to the lifting top plate 5, and the lifting top plate 5 and the shelf board 4 are fixedly connected. The shelf board 4 cannot rotate under the restriction of the support column 3 and can only move in the vertical direction. Then, the rotation of the screw rod 6 will drive the shelf board 4 to form a vertical movement. The screw rod 6 itself is arranged in the vertical direction, and the lower end of the screw rod 6 is rotatably connected to the support bottom plate 2, so that the screw rod 6 itself can rotate along the circumference of the screw rod 6. When the screw rod 6 has an appropriate pitch and sufficient friction, the screw rod 6 is in a self-locking state without external force, and the gravity of the shelf board 4 is borne on the screw rod 6, which will not cause the screw rod 6 to rotate, and the shelf board 4 will not fall. The adjustment method of the screw rod 6 is stable. The rotation of the screw rod 6 is driven by the rotating shaft 9, and the second bevel gear 12 is installed on the rotating shaft 9. The first bevel gear 11 is installed on the screw rod 6. After the first bevel gear 11 is meshed with the second bevel gear 12, the rotation direction of the rotating shaft 9 is changed to the horizontal direction. The horizontal rotating shaft 9 is more convenient for the staff to drive the screw rod 6 to rotate.
[0025] like Figure 4 As shown, further, the front side of the shelf board 4 is provided with an L-shaped slide groove 41, and the L-shaped slide groove 41 includes a vertical groove and a horizontal groove, the vertical groove is connected to the upper surface of the shelf board 4, and the horizontal groove is connected to the front side of the shelf board 4; two L-shaped sliding screws 43 are arranged in the L-shaped slide groove 41, and the two sliding screws 43 are located at one end of the vertical groove and are fixedly connected with a partition 7, and the partition 7 is located on the shelf board 4. The two partitions 7 are placed in parallel, and the sliding screw 43 is located at one end of the horizontal groove and passes through the shelf board 4, and a limited nut 44 is threadedly connected on this end. Goods can be placed on both the support bottom plate 2 and the shelf board 4, and the storage requirements of different goods are also different. The requirements for dust prevention during storage of goods such as electronic components are higher than those of ordinary goods. Two partitions 7 are arranged on the shelf board 4 to separate the middle space to prevent dust on both sides from entering the internal space, and the shelf board 4 has a certain height, away from the dust on the ground, and the shelf board 4 can mainly place goods with high dust prevention requirements. The position of the partition 7 can be adjusted by pushing the partition 7 on the shelf board 4, and the L-shaped sliding screw 43 at the bottom of the partition 7 slides in the first vertical slide groove and the horizontal slide groove, and the position of the partition 7 is adjusted horizontally, so that a better position of the partition 7 can be set during the placement of goods. One end of the sliding screw 43 passes through the side of the shelf board 4, and the partition 7 can be fixed by locking the limit nut 44. Conversely, the limit nut 44 can be loosened to adjust it again.
[0026] like Figure 5 As shown, further, a rear slide groove 42 is provided at the rear side of the shelf board 4, and the rear slide groove 42 extends in the left-right direction of the shelf board 4 and is provided in parallel with the L-shaped slide groove 41; a slider 45 is installed at the bottom of the partition board 7, and the slider 45 is slidably connected in the rear slide groove 42. After the slider 45 and the rear slide groove 42 are provided, the two ends of the bottom of the partition board 7 are slidably connected with the shelf board 4 through the slider 45 and the sliding screw 43 respectively, the rear slide groove 42 limits the swing of the partition board 7, and the use of the limit nut 44 to fix the rear partition board 7 can be more stable.
[0027] Preferably, there are four support columns 3, which are respectively installed on the four corners of the support bottom plate 2 and the top cover 1. A sliding sleeve 31 is fixedly connected to each of the four corners of the shelf board 4, and the sliding sleeve 31 is correspondingly slidably connected to the support column 3. Each support column 3 corresponds to a sliding sleeve 31, and all sliding sleeves 31 are fixedly connected to the shelf board 4. The shelf board 4 slides in the vertical direction through the sliding sleeve 31, the friction of the sliding sleeve 31 is smaller, and the shelf board 4 can slide more smoothly.
[0028] Further, a rocker 10 is fixedly mounted on one end of the rotating shaft 9 outside the sleeve 8. The rocker 10 can be provided to facilitate the user to exert force, and save effort when using.
[0029] Preferably, the width of the shelf board 4 is smaller than the width of the supporting bottom plate 2, and the lifting top plate 5 is installed on the side of the shelf board 4. The lifting top plate 5 is on the side of the shelf board 4, that is, the screw rod 6 is outside the shelf board 4, and the screw rod 6 will not interfere with the placement of goods on the shelf board 4.
[0030] The words “connection” and “fixation” appearing in the description of the present invention may refer to fixed connection, processing and forming, welding, or mechanical connection. The specific meanings of the above terms in the present invention shall be understood according to the specific circumstances.
