Description

Technical Field

[0001] The utility model relates to the technical field of shelves, and particularly relates to a shelf. Background Art

[0002] Through the design of a three-dimensional structure, the shelf can make full use of the warehouse space, thereby improving the capacity utilization rate of the warehouse and expanding the storage capacity of the warehouse. This structure improves the storage capacity per unit area of the warehouse, makes it convenient to access goods, can implement the principle of first in first out, and has 100% selection ability and smooth inventory turnover. The shelf meets the management needs of a modern enterprise's low-cost, low-loss, and high-efficiency logistics supply chain, thus saving more warehousing costs for the enterprise, and is therefore more and more widely used in real life.

[0003] In the related art, when placing items on the shelf, an operator usually pulls out the tray inside the shelf to facilitate placing the items on the shelf layer; however, the existing shelf trays have the following problems:

[0004] 1. After the tray inside the shelf is pulled out, it cannot be fixed, which easily causes sliding or shaking during the process of placing items, making it inconvenient for the operator to place items, and the sliding of the tray easily causes the items already placed inside the tray to shake, tilt, and fall, thereby affecting the placement efficiency of the items;

[0005] 2. After the tray is pulled out, it cannot automatically reset, that is, it needs to be manually pushed by the operator to make the tray return to the inside of the shelf, which causes a large physical consumption for the operator during the process of placing items multiple times.

[0006] Therefore, it is urgent to solve the problems that the tray cannot be fixed after being pulled out and the tray cannot be reset to the inside of the shelf. Summary of the Utility Model

[0007] In order to solve the deficiencies of the above-mentioned prior art, the utility model provides a shelf, which solves the problems that the tray cannot be fixed after being pulled out and the tray cannot be reset to the inside of the shelf.

[0008] The technical effects to be achieved by the utility model are realized through the following technical solutions:

[0009] The utility model provides a shelf, comprising:

[0010] A frame; and

[0011] A pull-out tray, and a plurality of pull-out trays are arranged in the frame to form a plurality of layers.

[0012] Among them, the drawer tray includes a tray assembly and a fixing plate assembly; the fixing plate assembly is connected to the frame body, and the tray assembly is slidably disposed on the fixing plate assembly in an automatically resetable manner, so that the tray assembly slides along a preset direction under an external force.

[0013] A limiting and clamping structure is provided between the tray assembly and the fixing plate assembly to limit the automatic reset of the tray assembly.

[0014] In some implementation manners, the tray assembly is slidably connected to the fixing plate assembly through a sliding structure, and the sliding structure includes a guide rod disposed on the tray assembly and a guide groove disposed on the fixing plate assembly and slidably matched with the guide rod.

[0015] In this implementation manner, the guide rod and the guide groove are slidably matched, so that the tray assembly slides more smoothly and stably relative to the fixing plate assembly. On the one hand, it is more convenient for the operator to draw the tray assembly to place items. On the other hand, the service life of the tray assembly and the fixing plate assembly is improved, and thus the reliability of the drawer tray is improved.

[0016] In some implementation manners, the limiting and clamping structure includes a limiting member disposed on the guide rod and a limiting groove extending from the guide groove. The limiting groove is used for the limiting member to pass through when limiting the automatic reset of the tray assembly. The limiting member and the limiting groove are relatively located at both ends of the tray assembly and / or the fixing plate assembly; the tray assembly is pulled to make the limiting member pass through the limiting groove and be fixed on the periphery of the guide groove to limit the automatic reset of the tray assembly.

[0017] In some implementation manners, the limiting and clamping structure further includes a fixing block disposed on the guide rod and a fixing groove connected to the guide groove and cooperatively clamped with the fixing block. When the tray assembly automatically resets, the fixing block is clamped in the fixing groove.

[0018] In this implementation manner, when the tray assembly returns to the shelf layer, the fixing block and the fixing groove are cooperatively clamped, so that the tray assembly is fixed on the fixing plate assembly, avoiding the problem that the goods in the tray assembly shake and pour due to the sliding of the tray assembly on the fixing plate assembly.

[0019] In some implementation manners, the tray assembly realizes sliding reset through an automatic reset structure, and the automatic reset structure includes:

[0020] An installation part, disposed on the fixing plate assembly, and provided with an installation window;

[0021] A fixing column, disposed on the tray assembly and opposite to the installation part; and

[0022] The first coil spring is installed on the installation part, and the telescopic end of the first coil spring passes through the installation window and is connected to the fixed column.

[0023] In this implementation, when the tray assembly is pulled out of the shelf layer relative to the fixed plate assembly, the movement of the tray assembly drives the movement of the fixed column, and then drives the movement of the telescopic end of the first coil spring, that is, the external force pulls the tray assembly to stretch the first coil spring; when the external force is removed, the first coil spring contracts, causing the tray assembly to automatically reset to the inside of the shelf layer, ensuring the reliability of the automatic reset of the pulled tray.

[0024] In some implementations, the tray assembly includes a tray body and a plurality of clamping plates installed on the tray body; the plurality of clamping plates extend with clamping parts, and the tray body is provided with clamping grooves that cooperate with the clamping parts for clamping.

[0025] In some implementations, the tray assembly further includes a partition vertically connected to the clamping plate.

[0026] In some implementations, the pulled tray further includes a pushing structure, and the pushing structure includes:

[0027] A pushing member, slidably disposed on a surface of the tray assembly facing away from the fixed plate assembly, and provided with an installation opening;

[0028] A fixing member, fixedly disposed on a surface of the tray assembly facing away from the fixed plate assembly, and disposed opposite to the pushing member; and

[0029] A second coil spring, installed on the pushing member, and the telescopic end of the second coil spring passes through the installation opening and is connected to the fixing member.

[0030] In some implementations, the tray assembly and the fixed plate assembly together form a first plate body and / or a second plate body, and the first plate body is clamped to the second plate body through a locking structure.

[0031] In this implementation, the first plate body can be clamped to the second plate body through the locking structure, so that the first plate body and the second plate body are detachably connected together.

[0032] In some implementations, the locking structure includes a sliding lock disposed on the first plate body and a card slot disposed on the second plate body and cooperating with the sliding lock for clamping;

[0033] The sliding lock includes a fixing part and a sliding part, the fixing part is disposed on the first plate body, the sliding part is slidably connected to the fixing part, and the sliding part is used for clamping in the card slot to realize the splicing between the first plate body and the second plate body.

[0034] In summary, the present utility model has at least the following advantages:

[0035] The shelf provided by the utility model has a limit clamping structure arranged between the tray assembly and the fixed plate assembly, so that one end of the tray assembly close to the shelf layer can be fixed on the fixed plate assembly after the tray assembly is pulled out, avoiding the problem that the tray slides or shakes during the process of placing items, resulting in the items in the tray shaking, tilting and falling, and further affecting the placing efficiency of the items;

[0036] Moreover, since the tray assembly is slidably arranged on the fixed plate assembly in an automatically resetable manner, when the clamping between the tray assembly and the fixed plate assembly is released and the tray assembly is not affected by external forces, the tray assembly can automatically reset into the shelf layer, solving the problem that the tray cannot be reset after being pulled out, and further causing a large physical consumption of the operator during the process of placing items multiple times.

[0047] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The described embodiments are some but not all of the embodiments of the present utility model.

[0048] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0049] Embodiment 1:

[0050] Please refer to the attached Figures 1 - 3 , the shelf of the present utility model includes a frame body 1 and a drawer tray 2.

[0051] Among them, please combine Figure 1 and Figure 2 , Figure 1 which shows the structural relationship between the drawer tray 2 and the frame body 1 in the embodiment of the present utility model, Figure 2 and which shows the structural relationship between the tray assembly 21, the fixed plate assembly 22 and the limit clamping structure 23 in the embodiment of the present utility model. Specifically, a plurality of drawer trays 2 are arranged in the frame body 1 to form a plurality of shelf layers 2a. The drawer tray 2 includes a tray assembly 21 and a fixed plate assembly 22; the fixed plate assembly 22 is connected to the frame body 1, and the tray assembly 21 is slidably arranged on the fixed plate assembly 22 in an automatically resetable manner, so that the tray assembly 21 slides along a preset direction under an external force; a limit clamping structure 23 is arranged between the tray assembly 21 and the fixed plate assembly 22 to limit the automatic reset of the tray assembly 21.

[0052] In this embodiment, the tray assembly 21 forms a shelf layer 2a for placing articles within the frame body 1, and a plurality of shelf layers 2a can be provided according to actual requirements; since the tray assembly 21 is slidably connected to the fixed plate assembly 22 in an automatically resetable manner, the tray assembly 21 can slide relative to the fixed plate assembly 22 under the pulling action of an external force, so that the tray can slide out of the shelf layer 2a to the outside of the shelf layer 2a, facilitating an operator to place and / or take out the articles within the tray assembly 21; when the tray assembly 21 is pulled out of the shelf layer 2a by pulling the tray assembly 2, since a limiting and clamping structure 23 is provided between the tray assembly 21 and the fixed plate assembly 22, one end of the tray assembly 21 close to the shelf layer 2a is clamped on the fixed plate assembly 22 after the tray assembly 21 extends out, thereby fixing the tray assembly 21 on the fixed plate assembly 22 to prevent the tray from sliding when the operator places articles; further, when the clamping between the tray assembly 21 and the fixed plate assembly 22 is released and the tray assembly 21 is not affected by an external force, the tray assembly 21 can automatically slide relative to the fixed plate and return to the shelf layer 2a to achieve the effect of automatic reset.

[0053] For the above-mentioned shelf, since a limiting and clamping structure 23 is provided between the tray assembly 21 and the fixed plate assembly 22, one end of the tray assembly 21 close to the shelf layer 2a can be fixed on the fixed plate assembly 22 after the tray assembly 21 is pulled out, avoiding the problem that the tray slides or shakes during the process of placing articles, resulting in the articles within the tray shaking, tilting and falling over, and thus affecting the placing efficiency of the articles; and since the tray assembly 21 is slidably arranged on the fixed plate assembly 22 in an automatically resetable manner, when the clamping between the tray assembly 21 and the fixed plate assembly 22 is released and the tray assembly 21 is not affected by an external force, the tray assembly 21 can automatically reset to the shelf layer 2a, solving the problem that the tray cannot be reset after being pulled out, and thus causing a large physical consumption for the operator during the process of placing articles multiple times.

[0054] In some preferred embodiments, please refer to Figure 3 , Figure 3It shows the structural relationship among the tray assembly 21, the fixed plate assembly 22 and the sliding structure 24 in the embodiment of the present utility model. Specifically, the tray assembly 21 is slidably connected to the fixed plate assembly 22 through the sliding structure 24. The sliding structure 24 includes a guide rod 241 provided on the tray assembly 21 and a guide groove 242 provided on the fixed plate assembly 22 and slidably engaged with the guide rod 241. The sliding fit between the guide rod 241 and the guide groove 242 makes the sliding of the tray assembly 21 relative to the fixed plate assembly 22 smoother and more stable. On the one hand, it is more convenient for the operator to pull out the tray 2 assembly to place items. On the other hand, it improves the service life of the tray assembly 21 and the fixed plate assembly 22, and further improves the reliability of pulling out the tray 2. It can be understood that the sliding fit between the tray assembly 21 and the fixed plate assembly 22 is not limited to using the guide rod 241 and the guide groove 242. Sliding members such as pulleys can also be provided on the tray assembly 21 and / or the fixed plate assembly 22 to make the tray assembly 21 slidably connected to the fixed plate assembly 22.

[0055] In some preferred embodiments, please refer to Figure 3 , Figure 3 It shows the structural relationship among the tray assembly 21, the fixed plate assembly 22 and the limit clamping structure 23 in the embodiment of the present utility model. Specifically, the limit clamping structure 23 includes a limiting member 231 provided on the guide rod 241 and a limiting groove 232 extending from the guide groove 242. The limiting groove 232 is used for the limiting member 231 to pass through when restricting the automatic reset of the tray assembly 21. The limiting member 231 and the limiting groove 232 are relatively located at both ends of the tray assembly 21 and / or the fixed plate assembly 22; pull the tray assembly 21 to make the limiting member 231 pass through the limiting groove 232 and be fixed to the periphery of the guide groove 242 to restrict the automatic reset of the tray assembly 21. Pull out the tray 2 assembly to make the guide rod 241 and the limiting member 231 slide in the guide groove 242, so that the tray assembly 21 slides relative to the fixed plate assembly 22; when the limiting member 231 and the limiting groove 232 are in the same axial position, the tray assembly 21 can be lifted relative to the fixed plate assembly 22, so that after the limiting member 231 passes through the limiting groove 232, pull out the tray assembly 21 relative to the shelf layer 2a again and place the tray assembly 21 on the fixed plate, that is, even after the limiting member 231 passes through the limiting groove 232, the limiting member 231 is far away from the limiting groove 232, and the limiting member 231 is abutted against the fixed plate, thereby restricting the automatic reset of the tray assembly 21.

[0056] In some preferred embodiments, the limit clamping structure 23 further includes a fixing block 233 provided on the guide rod 241 and a fixing groove 234 connected to the guide groove 242 and cooperating with the fixing block 233 for clamping. When the tray assembly 21 automatically resets, the fixing block 233 is clamped in the fixing groove 234. When the tray assembly 21 returns to the shelf layer 2a, the fixing block 233 and the fixing groove 234 cooperate for clamping, so that the tray assembly 21 is fixed on the fixing plate assembly 22, avoiding the problem that the goods in the tray assembly 21 shake and fall due to the sliding of the tray assembly 21 on the fixing plate assembly 22.

[0057] In some more preferred embodiments, please refer to Figure 3 , Figure 3 which shows the structural relationship among the tray assembly 21, the fixing plate assembly 22 and the automatic reset structure 25 in the embodiment of the present invention. Specifically, the tray assembly 21 realizes sliding reset through the automatic reset structure 25. The automatic reset structure 25 includes an installation part 251, a fixing column 252 and a first coil spring 253. The installation part 251 is provided on the fixing plate assembly 22 and is provided with an installation window 251a; the fixing column 252 is provided on the tray assembly 21 and is disposed opposite to the installation part 251; the first coil spring 253 is installed in the installation part 251, and the telescopic end of the first coil spring 253 passes through the installation window 251a and is connected to the fixing column 252. When the tray assembly 21 is pulled out from the shelf layer 2a relative to the fixing plate assembly 22, the movement of the tray assembly 21 drives the movement of the fixing column 252, and further drives the movement of the telescopic end of the first coil spring 253, that is, the external force pulls the tray assembly 2 to cause the first coil spring 253 to stretch; when the external force is removed, the first coil spring contracts, so that the tray assembly 21 automatically resets to the inside of the shelf layer 2a, ensuring the reliability of the automatic reset of the pulled tray 2; moreover, the first coil spring 253 is installed in the installation part 251, avoiding the problem that the first coil spring 253 rubs against external components and thus cannot normally expand and contract.

[0058] Embodiment 2:

[0059] The difference between this embodiment and Embodiment 1 is that in this embodiment, further structural optimization is made to the shelf of the present invention. Please refer to the attached Figure 4 , Figure 4 which shows the structural relationship between the tray body 211 and the clamping plate 212 in the embodiment of the present invention.

[0060] Among them, the tray assembly 21 includes a tray body 211 and a plurality of clamping plates 212 installed on the tray body 211; the plurality of clamping plates 212 extend with clamping parts 212a, and the tray body 211 is provided with clamping grooves 211a cooperating with the clamping parts 212a for clamping.

[0061] In this embodiment, a plurality of clamping portions 212a are clamped in the clamping grooves 211a to realize the clamping of the clamping plate 212 on the tray body 211, so that the clamping plate 212 and the tray body 211 are detachably connected together, which is more suitable for placing articles of different specifications. It can be understood that the operator can increase or decrease the number of clamping plates 212 to increase or decrease the placement area of the articles. Moreover, by providing the clamping plate 212 on the tray body 211, the clamping plate 212 can protect the tray body 211, so that the articles do not directly contact the tray body 211, thereby extending the service life of the tray body 211 and further ensuring the reliability of the tray body 211.

[0062] In some preferred embodiments, the tray assembly 21 further includes a partition 213 vertically connected to the clamping plate 212. The clamping plate 212 is provided with a clamping groove for the partition 213 to be clamped, so that the partition 213 and the clamping plate 212 are detachably connected together; and the horizontal plane where the top of the partition 213 is located is higher than the horizontal plane where the clamping plate 212 is located. In this way, different types of articles can be distinguished by setting the partition 213. Moreover, when the height of the placed articles is relatively high, the partition 213 can prevent the articles from tilting. The installation direction of the partition 213 can be the same as the sliding direction of the tray body 211 or perpendicular to the sliding direction of the tray body 211. In this embodiment, the installation direction of the partition 213 is the same as the sliding direction of the tray body 211.

[0063] In some more preferred embodiments, please refer to Figure 4 , Figure 4 which shows the structural relationship between the tray assembly 21 and the pushing structure 26 in the embodiment of the present invention. Specifically, the drawer tray 2 further includes a pushing structure 26, and the pushing structure 26 includes a pushing member 261, a fixing member 262 and a second coil spring 263. The pushing member 261 is slidably disposed on the side of the tray assembly 21 facing away from the fixing plate assembly 22, and is provided with an installation opening 261a; the fixing member 262 is fixedly disposed on the side of the tray assembly 21 facing away from the fixing plate assembly 22 and is disposed opposite to the pushing member 261; the second coil spring 263 is installed on the pushing member 261, and the telescopic end of the second coil spring 263 passes through the installation opening 261a and is connected to the fixing member 262. When taking out an article from the tray body 211, the second coil spring 263 curls up and drives the pushing member 261 to slide towards the fixing member 262, so that the pushing portion pushes the article on the tray body 211 towards the fixing member 262, so that the article is always in a position convenient for the operator to take out. Moreover, the second coil spring 263 is installed in the pushing member 261, which not only ensures that the pushing member 261 can automatically push the article, but also makes the overall structure of the drawer tray 2 more compact, improving the overall structural compactness.

[0064] Embodiment 3:

[0065] The difference between this embodiment and embodiment 2 is that this embodiment further optimizes the structure of the shelf of the utility model. Figures 5 - 7 .

[0066] Among them, see Figure 5 , Figure 5 The specific structure of the first plate 27 and / or the second plate in the embodiment of the utility model is illustrated. Specifically, the tray assembly 21 and the fixed plate assembly 22 together form the first plate 27 and / or the second plate, and the first plate 27 is clamped to the second plate through the locking structure 28.

[0067] In this embodiment, the first plate 27 can be connected to the second plate through the locking structure 28, so that the first plate 27 and the second plate are detachably connected together; it can be understood that according to the actual needs of placing items, multiple plates can be selected to be spliced ​​together to increase the placement area of ​​the items, or when the placement area required for the items is small, the placement area of ​​the items can be reduced by removing the redundant plates. Since the plates can be spliced, the volume of the plates does not need to be adapted to the size of the items placed one-to-one, which is more convenient for storage. Of course, the first plate 27 and the second plate are not limited to being spliced ​​by the locking structure 28, and can also be spliced ​​by means of a card block slot 282 or the like.

[0068] In some preferred embodiments, see Figure 6 , Figure 6 The schematic diagram shows the structural relationship between the first plate 27 and / or the second plate and the locking structure 28 in the embodiment of the utility model. Specifically, the locking structure 28 includes a sliding locking buckle 281 provided on the first plate 27, and a slot 282 provided on the second plate and engaged with the sliding locking buckle 281; the sliding locking buckle 281 includes a fixed portion 281a and a sliding portion 281b, the fixed portion 281a is provided on the first plate 27, and the sliding portion 281b is slidably connected to the fixed portion 281a, and the sliding portion 281b is used to be engaged in the slot 282 to achieve the splicing between the first plate 27 and the second plate. The operator can slide the sliding part 281b so that one end of the sliding part 281b slides from the fixed part 281a into the slot 282 to achieve the splicing between the first plate body 27 and the second plate body. Sliding the sliding part 281b to disengage the sliding part 281b from the slot 282 can release the splicing between the first plate body 27 and the second plate body. The structure is simple and easy to operate, thereby improving the reliability of the pull-out tray 2.

[0069] See also Figure 7 , Figure 7It shows the specific structure of the shelf in the embodiment of the present utility model. In the shelf of the present utility model, since a limit clamping structure 23 is provided between the tray assembly 21 and the fixed plate assembly 22, one end of the tray assembly 21 close to the shelf layer 2a can be fixed on the fixed plate assembly 22 after the tray assembly 21 is pulled out, avoiding the problem that the tray slides or shakes during the process of placing items, resulting in the items in the tray shaking, tilting and falling, thus affecting the placement efficiency of the items; and since the tray assembly 21 is slidably arranged on the fixed plate assembly 22 in an automatically resetable manner, when the clamping between the tray assembly 21 and the fixed plate assembly 22 is released and the tray assembly 21 is not affected by external forces, the tray assembly 21 can automatically reset into the shelf layer 2a, solving the problem that the tray cannot be reset after being pulled out, thus resulting in a large physical consumption of the operator during the process of placing items multiple times.

[0070] In the present utility model, unless otherwise clearly defined and limited, the terms "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0071] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of this utility model is usually placed during use. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0072] In addition, the terms "horizontal", "vertical", "hanging", etc. do not mean that the components are required to be absolutely horizontal or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0073] In the present utility model, unless otherwise clearly defined and limited, the first feature being above or below the second feature may include the direct contact between the first and second features, or may include the contact between the first and second features through additional features therebetween rather than direct contact. Moreover, the first feature being above, on top of and over the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being below, under and beneath the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.
