Description

Technical Field

[0001] The utility model relates to the technical field of storage equipment, in particular to a shelf which is convenient for adjusting the height between layers. Background Art

[0002] In the modern warehousing and logistics industry, with the increasing diversification of commodity types and storage needs, higher requirements are placed on the flexibility and space utilization of shelf systems. Traditional shelves often adopt a fixed layer height design. Although this design is simple in structure and low in cost, its limitations are increasingly prominent when facing goods of different sizes and weights. Shelves with fixed layer heights are difficult to adapt to changes in the size of goods, resulting in serious waste of space, and are also inconvenient for the storage and management of goods.

[0003] For example, a storage shelf with adjustable layer spacing disclosed in Chinese patent CN217050066U is placed from bottom to top during use, and the shelves are raised or lowered according to the size of the goods. When the desired height is reached, the positioning pin L is inserted into the positioning hole closest to the first slider, and the positioning pin presses against the first slider, so that the second connecting rod is fixed, that is, the entire movable bracket remains fixed. However, in actual use, when the above structure is used to fix the position of the adjusted placement plate, it is also necessary to insert a pair of positioning pins into the positioning holes, which increases the time for adjusting the placement plate in disguised form. If only one positioning pin is inserted, the placement stability effect of the placement plate may be reduced. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following will further describe in detail the specific implementation manners of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0027] As Figures 1 - 3 shown, the shelf for facilitating the adjustment of the layer height in this embodiment includes a fixing plate 1, a plurality of placing plates 2 slidably arranged in the vertical direction on the fixing plate 1, a limiting rod 3 arranged on the fixing plate 1 for restricting the vertical sliding and position locking of the placing plates 2, a card slot 4 opened on the limiting rod 3 and facing the placing plates 2, and a spacing adjustment mechanism 5 horizontally and linearly arranged in the placing plates 2 for inserting into the card slot 4 to fix the positions of the placing plates 2. The spacing adjustment mechanism 5 includes a sliding rod 51 and a pushing block 52, and a driving mechanism 6 for driving the pushing block 52 to move relatively away from and relatively close to each other. The shelf for facilitating the adjustment of the layer height further includes a linkage shielding mechanism 7 for shielding the goods on the placing plates 2 to prevent them from falling. The shape of the pushing block 52 matches the shape of the card slot 4. A positioning slot for the horizontal linear sliding of the card is opened on the placing plate 2, and the shape of the positioning slot matches the shape of the pushing block 52.

[0028] When it is necessary to adjust the spacing between the placing plates 2, in the initial state, the pushing block 52 and the card slot 4 are in a clamped state. At this time, the sliding rod 51 is pulled in a direction away from the placing plate 2. During this process, the movement of the sliding rod 51 and through the driving mechanism 6 drive a plurality of pushing blocks 52 to move relatively away from the card slot 4 opened on the limiting rod 3 until the pushing block 52 disengages from the card slot 4, and then the spacing of the placing plates 2 can be adjusted. Just by pulling the sliding rod 51, a plurality of pushing blocks 52 and the pushing block 52 can be driven to move relatively away from and relatively close to each other, making the spacing adjustment of the placing plates 2 more stable, without the need for multiple frequent fixing operations, saving the time for adjusting the spacing of the placing plates 2 in disguise, and increasing the stability of the spacing adjustment of the placing plates 2.

[0029] As Figures 2 - 4 shown, the driving mechanism 6 further includes hinge rods 61, limiting blocks 62 and limiting slots 63; a pair of hinge rods 61 are respectively rotatably arranged on the sliding rod 51 and the pushing block 52; a pair of limiting blocks 62 are arranged in the placing plate 2; the limiting slots 63 are opened on the limiting blocks 62, and the limiting slots 63 are used to restrict the horizontal linear sliding of the pushing plate. A cavity 21 for the horizontal linear sliding of the sliding rod 51 is opened in the placing plate 2.

[0030] When it is necessary to move the pushing block 52 relatively closer to make the placing plate 2 slide in the vertical direction, first pull the sliding rod 51 outward, which can then drive a pair of rotatably connected hinge rods 61 to be pulled. When the hinge rod 61 is pulled by the sliding rod 51, during this process, the hinge rod 61 can move the pushing block 52 rotatably connected to the other end relatively closer in the horizontal linear direction along the limiting groove 63 opened on the limiting block 62 until the pushing block 52 moves out of the clamping groove 4 opened on the limiting rod 3. At this time, the placing plate 2 that loses the fixation of the pushing block 52 can adjust the spacing in the vertical direction. When it is necessary to adjust the spacing between the placing plates 2, only by pulling the sliding rod 51 can several pushing blocks 52 be driven to move relatively away from each other, and it is not necessary to operate multiple ones to realize the spacing adjustment of the placing plate 2, and the stability of the spacing adjustment of the placing plate 2 is increased.

[0031] As Figure 3 and Figure 4 shown, the driving mechanism 6 further includes a return spring 64 and a positioning rod 65; the return spring 64 is arranged on the sliding rod 51, and both ends of the return spring 64 are fixedly connected to the sliding rod 51 and the end of the placing plate 2 respectively; the positioning rod 65 is arranged in the placing plate 2, and the positioning rod 65 has a clearance fit with the pushing block 52.

[0032] When it is necessary to fix the position of the adjusted placing plate 2, release the sliding rod 51, and then the compressed return spring 64 is released. The return spring 64 drives the sliding rod 51 to slide in the horizontal linear direction along the cavity 21 opened in the placing plate 2. During this process, the hinge rod 61 can move a pair of pushing blocks 52 relatively away from each other along the limiting groove 63 until the pushing block 52 slides and engages into the clamping groove 4 opened on the limiting rod 3, so as to quickly engage the placing plate 2 into the clamping groove 4 opened on the limiting rod 3, reducing the time for adjusting the spacing of the placing plate 2 and achieving a quick adjustment of the spacing between the placing plates 2.

[0033] As Figures 1 - 5 shown, the linkage shielding mechanism 7 includes a second sliding block 71, a linear travel groove 72 and a shielding block 73; the second sliding block 71 is arranged on the sliding rod 51 and extends above the placing plate 2; the linear travel groove 72 is opened on the placing plate 2, and the linear travel groove 72 is used to limit the sliding of the second sliding block 71; the shielding block 73 is slidably arranged on the placing plate 2.

[0034] When the sliding rod 51 is pulled away from the placing plate 2, during this process, the second sliding block 71 can be driven to slide in the horizontal linear direction along the linear travel groove 72 opened on the placing plate 2. During this process, the second sliding block 71 can drive the shielding block 73 to rise at an inclined angle until the shielding block 73 is inclined to block the goods on the placing plate 2, so as to avoid that when adjusting the distance of the placing plate 2, the goods may fall due to the user's misoperation, endangering the user's safety.

[0035] As Figures 5 - 7 shown, the linkage shielding mechanism 7 further includes a positioning plate 74, a guide groove 75 and a rotating rod 76; the positioning plate 74 is arranged on the placing plate 2 and there are a pair of them; the guide groove 75 is opened on the positioning plate 74; the rotating rod 76 is slidably arranged in the guide groove 75, and the rotating rod 76 is fixedly connected to the shielding block 73. The guide groove 75 is arc-shaped to limit the rising of the shielding plate and the rotating rod 76 at an inclined angle.

[0036] When the second sliding block 71 slides along the linear travel groove 72, during this process, the shielding plate and the rotating rod 76 can be driven to rise at an inclined angle along the guide groove 75 opened on the positioning plate 74 until the end of the shielding plate connected to the rotating rod 76 is lifted. Furthermore, when the second sliding block 71 slides and the sliding rod 51 moves away from the outside of the placing plate 2, the shielding plate and the rotating rod 76 can be driven to regularly and stably lift and block along the guide groove 75.

[0037] As Figure 7 shown, the linkage shielding mechanism 7 further includes a mounting plate 77 and a circular rod 78; the mounting plate 77 is arranged on the shielding plate and there are a pair of them; the circular rods 78 are respectively rotatably arranged on the mounting plate 77 and the second sliding block 71.

[0038] When the shielding plate is pushed by the second sliding block 71, during this process, the second sliding block 71 can push the mounting plate 77 and the shielding plate connected by rotation through the circular rod 78. Since the connecting ends of the circular rod 78 with the second sliding block 71 and the shielding plate are rotatably connected, the shielding plate can swing freely when pushed by the second sliding block 71.

[0039] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
