Abstract
Description
Technical Field
[0001] This utility model relates to the field of warehousing and logistics technology, and in particular to a fixing device, shelf assembly and rack. Background Technology
[0002] Shelving is a three-dimensional structure used for storing and preserving goods. Among them, beam shelving, as an important type of warehousing equipment, is widely used in logistics warehousing, supermarkets, bookstores, factories, and many other industries. Beam shelving mainly consists of uprights, beams, and shelves. During assembly, the beams are first connected to the uprights, then the shelves are placed on the beams, and finally, the shelves are secured to the beams with multiple bolts. Because multiple bolts need to be tightened during shelf installation, the installation efficiency is relatively low.
[0003] In existing technology, a bending component for fixing shelves secures the shelf by fastening its C-shaped fixing part to the crossbeam and having its spring clip engage with the shelf's locking hole, eliminating the need for additional bolts. However, since the bending component and shelf are only connected by the spring clip and locking hole, this connection can easily fail when the goods are too heavy or the shelf shakes, causing the connection between the crossbeam and the shelf to loosen and the shelf to fall off during shelf use.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0029] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0030] Firstly, please refer to Figure 1This embodiment provides a fixing device 1 for fixing a shelf 2 to an external component. The device includes a bent component 11 with a mounting groove 115. At least a portion of the external component can be clamped into the mounting groove 115. The fixing device 1 also includes a connector 12 and a fastener 13. The connector 12 is fixedly connected to the bent component 11 and supports the shelf 2. The fastener 13 passes sequentially through the shelf 2 and the connector 12 and is riveted to both the shelf 2 and the connector 12. The connector 12 and the bent component 11 form a limiting groove 123, and a portion of the structure of the shelf 2 can be confined within the limiting groove 123. Specifically, the mounting groove 115 is a U-shaped groove. This configuration, by securing at least a portion of the outer component in the mounting groove 115 and ensuring the top plate 111 fits against the top surface of the outer component, allows the bent component 11 to be tightly fastened to the outer component, guaranteeing a stable connection between the fixing device 1 and the outer component. The fastener 13 passes sequentially through the layer plate 2 to be fixed and the connector 12, and is riveted to both the layer plate 2 and the connector 12, locking the relative positions of the connector 12 and the layer plate 2. Furthermore, the fastener 13 can be installed without tools, reducing installation time and improving the fixing efficiency compared to screwing or welding. The installation efficiency of the device 1 is improved. At the same time, when the riveted fastener 13 is subjected to axial force, it will undergo a certain deformation, which will generate a certain prestress between the fastener 13, the wall of the fastening hole 1211 and the layer plate 2 to be fixed, further ensuring the reliable connection between the fixing device 1 and the layer plate 2 to be fixed. The connecting piece 12 and the bending piece 11 form a limiting groove 123, and part of the structure of the layer plate 2 to be fixed can be limited in the limiting groove 123, further limiting the layer plate 2 to be fixed, ensuring the reliability of the connection between the layer plate 2 to be fixed and the fixing device 1, and preventing the layer plate 2 to be fixed from falling off the fixing device 1.
[0031] Optionally, the top plate 111 is provided with process holes, which facilitates the positioning of the bending part 11 by the processing equipment during processing, thereby improving the processing accuracy.
[0032] Alternatively, please refer to Figure 2The connector 12 includes a support plate 121 and a connecting plate 122. One end of the connecting plate 122 is fixedly connected to the first side plate 112 and forms a limiting groove 123 with the bent member 11. The other end of the connecting plate 122 is connected to the support plate 121. The support plate 121 supports the layer plate 2 to be fixed. The support plate 121 has a plurality of fastening holes 1211 spaced apart. Fasteners 13 can pass through the layer plate 2 to be fixed and selectively rivet to one of the plurality of fastening holes 1211. Preferably, the plurality of fastening holes 1211 are spaced apart on the support plate 121 along the length direction of the outer component. This arrangement facilitates the adjustment of the relative position between the fixing device 1 and the layer plate 2 to be fixed when installing the fixing device 1, reduces the assembly accuracy requirements of the fixing device, and facilitates the installation of the fixing device.
[0033] Optionally, the fastener 13 is a tree-shaped rivet. Preferably, the tree-shaped rivet is made of plastic. This design allows the toothed prongs of the tree-shaped rivet to have a certain degree of elasticity, enabling manual pressing into the fastening hole 1211 and providing an interference fit with the fastening hole 1211. It is also difficult to pull out, thus ensuring a reliable connection between the fixing device 1 and the layer 2 to be fixed, preventing detachment. In other embodiments, the fastener 13 can also be a semi-hollow rivet, an expansion rivet, etc., and the rivet can also be made of materials such as aluminum or copper. The rivet type and material in this embodiment and the accompanying drawings are merely examples.
[0034] In other embodiments, the fastener 13 may also be a pin, which locks the relative position between the connector 12 and the layer 2 to be fixed by means of a pin connection.
[0035] Alternatively, please refer to Figures 1 to 4 The bending component 11 also includes an operating component 114. The bending component includes a first side plate 112, a top plate 111, and a second side plate 113 connected in sequence. The first side plate 112, the top plate 111, and the second side plate 113 form a mounting groove 115. The bending component 11 has a first state of clamping the external component and a second state of separating from the external component. When the bending component is in the second state, the distance between the first side plate 112 and the second side plate 113 gradually decreases along the direction from the bottom of the mounting groove 115 to the opening of the mounting groove 115. With this configuration, when the first side plate 112 is in the first state, the first side plate 112 can still keep its second end close to the second side plate 113 relative to its first end, so that the mounting groove 115 forms a gradually narrowing opening, thereby preventing the external component from coming loose from the mounting groove 115.
[0036] The operating component 114 is connected to the end of the second side plate 113 away from the top plate 111. When the operating component 114 is subjected to external force, the operating component 114 can drive the second side plate 113 to move away from the first side plate 112.
[0037] Alternatively, please refer to Figure 1 and Figure 4The bending component 11 includes a first side plate 112, a top plate 111, a second side plate 113, and an operating component 114. The first side plate 112, the top plate 111, and the second side plate 113 are sequentially connected and form a mounting groove 115. The operating component 114 is connected to the second side plate 112. External force can drive the operating component 114 to move away from the first side plate 112, thereby increasing the distance between the end of the second side plate 113 away from the top plate 111 and the first side plate 112. This configuration allows the external component to be quickly clamped into the mounting groove 115 via the operating component 114, improving work efficiency. Preferably, the operating component 114 is an operating plate, facilitating the application of external force.
[0038] Alternatively, please refer to Figure 1 The operating member 114 is connected to the end of the second side plate 113 away from the top plate 111. The connection between the second side plate 113 and the operating member 114 has a protrusion facing into the mounting groove 115. From the end of the operating member 114 connected to the second side plate 113 towards the end away from the protrusion, the operating member 114 is inclined towards the outside of the mounting groove 115. This arrangement creates a gradually widening opening between the operating member 114 and the first side plate 112 along the direction of the outer component's detachment, making it difficult for the outer component, which has already entered the mounting groove 115, to detach. Simultaneously, the inclined orientation of the operating member 114 towards the outside of the mounting groove 115 provides a guiding effect, reducing the risk of scratches or damage to the outer component during its entry into the mounting groove 115. When the bending member 11 clamps the outer component, the protrusion abuts against the outer component, increasing the friction between the bending member 11 and the outer component, further ensuring the reliability of the fixing device 1.
[0039] Optionally, a rounded corner is provided at the connection between the top plate 111 and the first side plate 112. With this configuration, when the external component enters the mounting groove 115, the connection between the top plate 111 and the first side plate 112 can undergo a certain deformation, making the opening of the mounting groove 115 larger, which facilitates the entry of the external component. The rounded corner can reduce stress concentration at the connection between the top plate 111 and the first side plate 112, avoid fatigue fracture of the bent part 11, and extend the fatigue life of the bent part 11.
[0040] Optionally, a rounded corner is provided at the connection between the top plate 111 and the second side plate 113. With this configuration, when the external component enters the mounting groove 115, the connection between the top plate 111 and the second side plate 113 can undergo a certain deformation, making the opening of the mounting groove 115 larger. The rounded corner can reduce stress concentration at the connection between the top plate 111 and the first side plate 112, avoid fatigue fracture of the bent component 11, and extend the fatigue life of the bent component 11.
[0041] Secondly, please refer to Figures 3 to 6This embodiment provides a shelf assembly, which includes a shelf 2 to be fixed and the aforementioned fixing device 1. The shelf 2 to be fixed includes a shelf body 21. The end of the shelf body 21 connected to the fixing device 1 is provided with a support part 22 and a limiting part 23 connected in sequence. The support part 22 is supported on the connector 12 of the fixing device 1. Fasteners 13 are riveted to the support part 22 and the connector 12. The limiting part 23 is limited in the limiting groove 123. With this configuration, by fixing the support part 22 to the support plate 121, a reliable connection between the shelf 2 to be fixed and the fixing device 1 is ensured. The limiting part 23 is limited in the limiting groove 123, which can prevent the fire-fighting shelf from sliding along the length direction of the shelf 2 to be fixed before the fastener 13 is installed or when the fastener 13 fails, thus preventing the shelf 2 to be fixed from slipping off, and further improving the reliability of the shelf assembly.
[0042] Specifically, the shelf 2 to be fixed is configured as a fire-resistant shelf, which can play a fire-prevention role in the event of a fire. For example, when the shelf assembly is applied to a shelf, the fire-resistant shelf can isolate different storage areas, preventing fire from spreading from one area to another, thereby reducing the loss of goods on the shelf. In other embodiments, the shelf assembly can also be applied to furniture manufacturing, such as the connection of furniture parts; bridge engineering, such as the connection of bridge decks and beams, etc.
[0043] Preferably, the support portion 22 is provided with a waist-shaped hole 221, the length direction of which is perpendicular to the length direction of the outer component. The fastener 13 passes through the waist-shaped hole 221 of the support portion 22 and the fastening hole 1211 of the support plate 121 in sequence, and the fastener 13 is riveted to the support plate 121. The waist-shaped hole 221 facilitates the alignment of the waist-shaped hole 221 with the fastening hole 1211, thereby facilitating the assembly of the fastener 13.
[0044] Specifically, a connecting piece is provided at the end of the shelf body 21 that connects to the fixing device 1, and the connecting piece is bent to form a support part 22 and a limiting part 23.
[0045] Optionally, the limiting part 23 and the supporting part 22 are arranged at an angle. Preferably, the angle between the limiting part 23 and the supporting part 22 is not greater than 90 degrees. With this arrangement, before the fastener 13 is installed or when the fastener 13 fails, the shelf 2 to be fixed can be prevented from sliding along the length direction of the waist-shaped hole 221, which would cause the fire-fighting shelf to slip off, and further improve the reliability of the shelf assembly.
[0046] Preferably, the angle between the limiting part 23 and the supporting part 22 is 90 degrees. This provides space for adjusting the position of the fire-fighting shelf relative to the longitudinal direction of the oblong hole 221. In other embodiments, the limiting part 23 may also be bent towards the shelf body 21, so that the end of the limiting part 23 away from the supporting part 22 abuts against the connecting plate 122, thereby restricting the movement of the fire-fighting shelf along the longitudinal direction of the oblong hole 221. This embodiment and the accompanying drawings do not impose specific limitations on the angle between the limiting part 23 and the supporting part 22; those skilled in the art can set it as needed.
[0047] Preferably, please refer to Figure 5 Multiple shelf assemblies are spaced apart along the length of the outer component. This arrangement increases the number of stress points between the shelf and the outer component, resulting in a more uniform stress distribution, improving the fatigue life of the fixing device 1, and further enhancing the connection reliability of the shelf assemblies.
[0048] Thirdly, this embodiment provides a shelf, which includes an outer component and the aforementioned shelf assembly. A crossbeam 3 constitutes the outer component, and at least a portion of the crossbeam 3 is secured in the mounting groove 115 of the fixing device 1. Specifically, the crossbeam 3 can be an integral beam, a double-sided clamping beam, a single-sided clamping beam, etc.
[0049] The steps for fixing the fire protection floor slab to the crossbeam 3 using fixing device 1 are as follows:
[0050] First, the bent parts 11 of multiple fixing devices 1 are installed onto two spaced-apart crossbeams 3. The multiple fixing devices 1 are spaced apart along the length of the crossbeams 3, and at least a portion of the crossbeams 3 is secured in the mounting groove 115. Next, the fire-resistant shelf is placed between the two spaced-apart crossbeams 3, and the position of the shelf is adjusted so that the slotted hole 221 on the extension plate corresponds to one of the multiple fastening holes 1211 of the fixing device 1. Finally, the fastener 13 passes through the fastening hole 1211 corresponding to the slotted hole 211 and is riveted to the fire-resistant shelf. The fixing devices 1 fix the position of the fire-resistant shelf relative to the crossbeams 3 of the shelf, preventing the connection between the crossbeams 3 and the fire-resistant shelf from loosening and causing the fire-resistant shelf to fall off during the use of the shelf. At the same time, the riveting method using the fastener 13 allows for installation without the need for additional tools, improving the installation efficiency of the shelf.
[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
