Description

Technical Field

[0001] This utility model relates to the field of shelving technology, specifically a four-layer shelving unit. Background Technology

[0002] Storage shelves are made of shelves and supports for storing miscellaneous items. They are mostly supported by strip supports and reinforced by shelves. They have a unique shape, ingenious design, are easy to assemble and disassemble, are clean and bright, and have an open design.

[0003] Patent CN2902052Y discloses a modular shelving unit, including a support frame and shelves placed on the support frame. The support frame and shelves together constitute a shelving unit. The length and width of the shelves determine the length and width of the shelving unit. The support frame consists of trapezoidal uprights, upper and lower horizontal bars, and shelf horizontal bars. The height of the shelving unit is extended through connectors between the uprights. Positioning holes are provided on the small surface of the trapezoidal uprights for inserting shelf horizontal bars. The upper and lower horizontal bars are connected to the uprights via right-angle connectors. The structural features of this invention are: it can be arbitrarily assembled and infinitely extended according to different sites and situations; in terms of horizontal length, the length of a single shelving unit can be adjusted by selecting shelves of different lengths, and the length of multiple connected shelving units can be adjusted by selecting shelves of different lengths or by assembling multiple shelving units to control the length; in terms of shelving width, it can be adjusted by selecting shelves of different widths, making adjustment and assembly quite convenient.

[0004] The above-mentioned device is fixed by plugging and screws. This connection method is not very suitable when facing metal plates. For example, when the device shakes, the connection between the upper and lower layers is prone to loosening, which will affect the overall strength and stability of the device. Therefore, we propose a four-layer shelf. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a four-layer shelving unit. By setting a connecting column between the top and bottom shelves and a fixing screw at the contact point between the connecting column and the upright, the top and bottom shelves are connected and fixed by screwing the fixing screw into the first and second threaded holes. This results in a stronger connection between the two shelves and prevents them from loosening when exposed to external vibrations.

[0006] In order to solve the above-mentioned technical problems, the present invention solves the problem that metal shelves are prone to loosening at the connection points due to external vibration when they are assembled and fixed with screws.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A four-tiered shelving unit includes a bottom shelf and a top shelf, connecting columns, and auxiliary components. Both the bottom and top shelves have welded-in uprights and trays. Multiple connecting columns are located between the uprights of the bottom and top shelves. Each connecting column has a fixing screw on both its upper and lower sides. The top of each upright of the bottom shelf has a first threaded hole for threaded connection with the fixing screw. The bottom of each upright of the top shelf has an auxiliary column with a second threaded hole for threaded connection with the fixing screw. The auxiliary components are located within the top shelf and are used to house the uprights of the top shelf.

[0009] Preferably, a limiting block is fixedly provided at the top of the auxiliary column, and a limiting groove is provided at the bottom of the column of the top shelf. The limiting block is rotatably disposed in the limiting groove, which facilitates fixing the connecting column to the top shelf.

[0010] Preferably, sealing gaskets are provided on both the upper and lower sides of the connecting post, and the sealing gaskets are fixed in the annular groove provided on the outer side of the connecting post to improve the airtightness of the connection and prevent external moisture from entering and corroding the threads.

[0011] Preferably, the bottom of the upright of the top shelf, the upper and lower sides of the auxiliary column, the upper and lower sides of the connecting column, and the top of the upright of the bottom shelf are all frosted surfaces to increase surface roughness and reduce the generation of high-frequency noise when they rub against each other.

[0012] Preferably, the auxiliary component includes auxiliary frames evenly distributed on the top of the uprights of the top shelf. The auxiliary frames are fixedly mounted on the bottom of the tray of the top shelf. A fixed shaft is fixedly mounted in the slot of the auxiliary frame. The top of the uprights of the top shelf is rotatably mounted on the fixed shaft, which can store the uprights, thereby reducing the space occupied and facilitating transportation.

[0013] Preferably, the slotting direction of the auxiliary frame is the same as the long side direction of the tray, so that the column can be stored at the bottom of the tray.

[0014] Preferably, a baffle is fixedly provided on the outer side of the slot of the auxiliary frame. The baffle is located on the side of the auxiliary frame away from the center of the tray. The baffle plays a limiting role and can ensure that when the upright of the top shelf is fully extended and vertical, the tray of the top shelf will not tilt in a certain direction.

[0015] Preferably, an X-shaped reinforcing rod is fixed between adjacent columns to improve the connection strength between the columns.

[0016] Preferably, the fixing screws on the upper and lower sides of the connecting column have the same thread direction, which makes it convenient for the connecting column to fix the uprights of the top shelf, the uprights of the bottom shelf, and the connecting column at the same time when rotating.

[0017] Preferably, the bottom of the column of the bottom shelf is provided with a support foot. The support foot is threadedly engaged with a third threaded hole provided at the bottom of the column of the bottom shelf. The height of each support foot can be adjusted according to the flatness of the ground to ensure the level of the tray.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model provides a connecting column between the top shelf and the bottom shelf, and a fixing screw at the contact point between the connecting column and the upright column. The fixing screw is screwed into the first threaded hole and the second threaded hole to connect and fix the top shelf and the bottom shelf, which makes the connection strength of the two shelves higher and will not loosen when exposed to external vibration.

[0020] By rotating the uprights of the top shelf, the uprights can be stored at the bottom of the pallet during transportation, thereby reducing space occupation and saving transportation costs. Attached Figure Description

Example

[0034] Please see Figures 1-7 A four-layer shelving unit includes a bottom shelf 1 and a top shelf 2, a connecting column 5 and an auxiliary component 10. The bottom shelf 1 and the top shelf 2 are each equipped with a column 3 and a support plate 4 by welding. An X-shaped reinforcing rod 17 is fixed between adjacent columns 3 to improve the connection strength between the columns 3.

[0035] Multiple connecting posts 5 are provided, located between the uprights 3 of the bottom shelf 1 and the top shelf 2. Each connecting post 5 has a fixing screw 6 fixed on both its upper and lower sides. The threads of the fixing screws 6 on both sides of the connecting post 5 are in the same direction, allowing the connecting post 5 to simultaneously fix the uprights 3 of the top shelf 2, the uprights 3 of the bottom shelf 1, and the connecting post 5 when rotating. The top of the upright 3 of the bottom shelf 1 has a first threaded hole 7 for threaded connection with the fixing screw 6. The bottom of the upright 3 of the top shelf 2 has an auxiliary post 8, and a limiting block 11 is fixedly installed on the top of the auxiliary post 8. The bottom of the upright column 3 of the top shelf 2 is provided with a limiting groove 12. The limiting block 11 is rotatably disposed in the limiting groove 12. The connecting column 5 is fixed to the top shelf 2 by rotating the auxiliary column 8. The bottom of the auxiliary column 8 is provided with a second threaded hole 9 that is threadedly connected to the fixing screw 6. The upper and lower sides of the connecting column 5 are provided with sealing gaskets 13. The sealing gaskets 13 are fixed in the annular groove provided on the outside of the connecting column 5. The sealing gaskets 13 can improve the airtightness of the connection and prevent external moisture from entering and corroding the threads. The auxiliary component 10 is disposed in the top shelf 2 and is used to store the upright column 3 of the top shelf 2.

[0036] The following describes some embodiments of this application in detail with reference to the accompanying drawings:

[0037] Please see Figures 1-7 By setting a connecting post 5 between the top shelf 2 and the bottom shelf 1, and setting a fixing screw 6 at the contact point between the connecting post 5 and the upright post 3, the top shelf 2 and the bottom shelf 1 are connected and fixed by screwing the fixing screw 6 into the first threaded hole 7 and the second threaded hole 9, so that the connection strength of the two shelves is higher and they will not loosen when faced with external vibration.

[0038] The auxiliary component 10 includes auxiliary frames 14 evenly distributed on the top of the uprights 3 of the top shelf 2. The auxiliary frames 14 are fixedly installed on the bottom of the tray 4 of the top shelf 2. A fixed shaft 15 is fixedly installed in the slot of the auxiliary frame 14. The slot direction of the auxiliary frame 14 is the same as the long side direction of the tray 4. The top of the uprights 3 of the top shelf 2 is rotatably mounted on the fixed shaft 15, which can store the uprights 3, thereby reducing the space occupied and facilitating transportation.

[0039] Furthermore, to prevent the upright 3 from rotating excessively within the auxiliary frame 14, which could cause the upright 3 to accidentally wobble when it is perpendicular to the support plate 4 and about to connect with the bottom shelf 1, such as... Figure 7 As shown, a baffle 16 is fixedly installed on the outside of the slot of the auxiliary frame 14. The baffle 16 is located on the side of the auxiliary frame 14 away from the center of the support plate 4. The baffle 16 plays a limiting role and can effectively ensure that when the upright 3 of the top shelf 2 is fully unfolded and vertical, the support plate 4 of the top shelf 2 will not tilt in a certain direction.

[0040] To ensure the strength of the connection between the top shelf 2 and the bottom shelf 1, and to prevent the connection from loosening when the device is subjected to external vibration, the implementation method of this application will be described as follows:

[0041] First, rotate the upright 3 of the top shelf 2 to be perpendicular to the tray 4. At this time, the baffle 16 blocks and limits the outside of the upright 3.

[0042] Then, the connecting post 5 is fixed to the upright post 3 of the bottom shelf 1 by screwing the fixing screw 6 into the first threaded hole 7;

[0043] Finally, place the upright 3 of the top shelf 2 above the bottom shelf 1, rotate the auxiliary column 8, and screw the auxiliary column 8 onto the fixing screw 6 at the top of the connecting column 5 to fix the top shelf 2 and the bottom shelf 1.

[0044] When screwing the upright 3 of the top shelf 2 onto the connection, the fixing screw 6 is screwed into the second threaded hole 9 by tightening diagonally in stages. This can evenly apply force to multiple directions of the fixing screw 6, avoiding the force being biased in one direction, thereby maintaining the balance and stability of the fixing screw 6. This helps to prevent the device from deforming or being damaged due to uneven force distribution.

[0045] In some embodiments of this technical solution, in order to reduce the noise generated when the connecting column 5 and the auxiliary column 8 are rotated, the bottom of the column 3 of the top shelf 2, the upper and lower sides of the auxiliary column 8, the upper and lower sides of the connecting column 5, and the top of the column 3 of the bottom shelf 1 are all made with frosted surfaces. The frosted surfaces can increase the surface roughness and reduce the generation of high-frequency noise when they rub against each other. At the same time, the tiny protrusions and depressions between the frosted surfaces will interlock with each other when they rub against each other, thereby reducing the propagation of vibration and noise to a certain extent.

[0046] In some embodiments of this technical solution, such as Figure 2 As shown, in order to ensure that the tray 4 remains horizontal when the device is placed on an uneven ground, support feet 18 are provided at the bottom of the column 3 of the bottom shelf 1. The support feet 18 are threaded into the third threaded hole at the bottom of the column 3 of the bottom shelf 1, so that the height of each support foot 18 can be adjusted according to the flatness of the ground, thereby ensuring that the tray 4 is horizontal.

[0047] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
