Description

Technical Field

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

[0002] There are various types and different structures of shelves in the prior art. However, there is still room for improvement. For example, floor-standing shelves have good load-bearing capacity, but relatively large floor area, and columns are required at all four corners, resulting in relatively high material costs. Wall-mounted shelves, on the other hand, have relatively small floor area and save some material costs such as columns, but their load-bearing performance is relatively poor. Another common shortcoming of the shelves in the prior art is that the connection structures between components are relatively complex and the installation speed is relatively slow. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a shelf with relatively small floor area, relatively low material cost and good load-bearing capacity.

[0004] The technical solution of the utility model is to provide a shelf, which includes outer columns supported on the ground and a cross-frame assembly connected to the outer columns. The cross-frame assembly includes inner longitudinal beams for fixing on the wall and two symmetrically arranged border cross beams. The inner ends of the two border cross beams are respectively hinged to the two ends of the inner longitudinal beam, and the outer ends of the two border cross beams are detachably connected to the outer longitudinal beam parallel to the inner longitudinal beam. The two ends of the outer longitudinal beam of the cross-frame assembly are detachably connected to their respective outer columns; at least one inner cross beam of the cross-frame assembly parallel to the border cross beam is connected to the inner longitudinal beam and the outer longitudinal beam.

[0005] After adopting the above structure, the shelf of the utility model has the following advantages: Since the inner cross beam of the cross-frame assembly can be fixed on the wall, and the inner ends of the two border cross beams of the cross-frame assembly are hinged to the inner longitudinal beam, and the outer ends of the two border cross beams are detachably connected to the outer longitudinal beam parallel to the inner longitudinal beam to form a rectangular frame, and the two ends of the outer longitudinal beam are detachably connected to the two outer columns supported on the ground, the shelf has relatively small floor area, relatively low material cost and good load-bearing capacity.

[0006] Furthermore, the outer longitudinal beam is a first C-shaped steel pipe, and vertical clamping plates are fixed at both ends. An inwardly convex vertical clamping block is fixed on the inner side of the vertical clamping plate, and the vertical clamping block is clamped into the wedge-shaped hole on the outer column that is large at the top and small at the bottom from top to bottom; the outer end of the border cross beam is accommodated in the groove of the first C-shaped steel pipe of the outer longitudinal beam, and a screw passes through the screw through hole of the first C-shaped steel pipe and is tightened into the threaded hole on the outer end plate of the border cross beam. After adopting the above structure, the connection structures between the outer longitudinal beam and the outer column and the border cross beam are both simple, the connection operations, namely the installations, are both convenient and fast, and the connection structures are both stable and reliable.

[0007] Further, the inner longitudinal beam is a second C-shaped steel pipe, and the frame cross beam is a third C-shaped steel pipe with one end that can be accommodated in the groove of the second C-shaped steel pipe. The hinge uses a hollow rivet for axial limitation, and the third C-shaped steel pipe can rotate relative to the second C-shaped steel pipe around the axis of the hollow rivet. After adopting the above structure, the free end of the hollow rivet is expanded. For example, with a steel cone and a hammer at the bottom, the hollow rivet can be axially limited, and the third C-shaped steel pipe can rotate relative to the second C-shaped steel pipe around the axis of the hollow rivet. Its hinge structure is simple, the hinge operation, i.e., installation, is convenient and fast, and the hinge structure is stable and reliable.

[0008] Further, the inner frame cross beam is a fourth C-shaped steel pipe. The inner end of the fourth C-shaped steel pipe of the inner frame cross beam is accommodated in the groove of the second C-shaped steel pipe of the inner longitudinal beam, and the outer end of the fourth C-shaped steel pipe of the inner frame cross beam is accommodated in the groove of the first C-shaped steel pipe of the outer longitudinal beam; both ends of the fourth C-shaped steel pipe of the inner frame cross beam are fixed to the first C-shaped steel pipe of the outer longitudinal beam and the second C-shaped steel pipe of the inner cross beam by first nylon expansion buckles. After adopting the above structure, the connection structures between the inner frame cross beam and the inner longitudinal beam and the outer longitudinal beam are all simple, the connection operations, i.e., installations, are all convenient and fast, and the connection structures are all stable and reliable.

[0009] Further, the inner longitudinal beam is fixed to the wall by screws. There are multiple screw through holes on the vertical plate of the second C-shaped steel pipe of the inner longitudinal beam, and the screw through holes are horizontally elongated through holes. After adopting the above structure, the fixation of the inner longitudinal beam to the wall is convenient, fast, stable and reliable, and there is a certain adjustment space for the horizontal position of the inner cross beam.

[0010] Further, the shelf of the present utility model further includes a cargo board supported on the inner longitudinal beam, the outer longitudinal beam, the frame cross beam and the inner frame cross beam. After adopting the above structure, it is more convenient to place and stack goods with a relatively small bottom area, making the shelf of the present utility model more widely applicable.

[0011] Further, the pallet is a goods mesh plate formed by welding a plurality of longitudinal round steel bars and a plurality of transverse round steel bars. The goods mesh plate is placed on the inner longitudinal beam, the outer longitudinal beam, the frame cross beam and the inner frame cross beam; the inner longitudinal beam, the outer longitudinal beam, the frame cross beam and the inner frame cross beam are all C-shaped steel pipes. The two ends of the plurality of transverse round steel bars are fixed to the upper cross plates of the C-shaped steel pipes of their respective longitudinal beams through nylon hoop straps with two second nylon expansion buckles, and / or the two ends of the plurality of longitudinal round steel bars are fixed to the upper cross plates of the C-shaped steel pipes of their respective frame cross beams through nylon hoop straps with two second nylon expansion buckles. After adopting the above structure, on the premise of ensuring the load-bearing and stacking of goods, the pallet adopts a goods mesh plate formed by welding a plurality of longitudinal round steel bars and a plurality of transverse round steel bars, which relatively saves the material cost of the pallet. Moreover, since the hoop straps with two second nylon expansion buckles can be used to fix the transverse round steel bars and / or longitudinal round steel bars of the goods mesh plate, the goods mesh plate can be fixed without tools, making the connection and fixation of the goods mesh plate with the longitudinal beam and / or the frame cross beam convenient, fast, stable and reliable.

[0012] Further, the outer column is a rectangular steel pipe with a vertically penetrating notch in the middle of the inner side plate along the whole length. The upper-large and lower-small wedge-shaped holes for engaging the vertical blocks of the vertical plates of the outer longitudinal beam are arranged on the outer side plate of the rectangular steel pipe. There are two upper-large and lower-small wedge-shaped holes in each row, and multiple upper-large and lower-small wedge-shaped holes are arranged at equal intervals up and down in each column; the shelf further includes a pallet supported on the inner longitudinal beam, the outer longitudinal beam, the frame cross beam and the inner frame cross beam. After adopting the above structure, the column is both firm and relatively material-saving, and has a regular rectangular shape, which is convenient for the vertical plate of the outer longitudinal beam to fit with it; the two upper-large and lower-small wedge-shaped holes in each row and the multiple upper-large and lower-small wedge-shaped holes arranged at equal intervals up and down on the outer side plate of the outer column set the basis for the connection structure of the outer column for vertically installing multiple cross-frame components and horizontally installing multiple cross-frame components.

[0013] Further, a plurality of cross-frame components are arranged vertically. After adopting the above structure, multiple layers of cross-frame components are added vertically, storing more items, with a compact structure, a small floor area, more concentrated stacking, more convenient access to goods, and relatively saving the labor cost of storage.

[0014] Further, a plurality of cross-frame components are arranged horizontally. After adopting the above structure, on the basis of the above-mentioned multiple layers of cross-frames, each layer of cross-frame components extends along the length direction, that is, horizontally, so that more items can be stored, the stacking is more concentrated, the storage scale is larger, and the applicable range of goods storage is wider.

Detailed implementation mode

[0029] The following further describes the detailed implementation mode of the present utility model in conjunction with the accompanying drawings. It should be noted here that the description of these detailed implementation modes is used to help understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various detailed implementation modes of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 shown.

[0031] The shelf of the utility model includes an outer column 1 supported on the ground and a cross-frame assembly 2 connected to the outer column 1. The structure of the cross-frame assembly 2 is as follows: The cross-frame assembly 2 includes an inner longitudinal beam 21 for fixing to the wall and two symmetrically arranged border cross beams 22. The inner ends of the two border cross beams 22 are respectively hinged to the two ends of the inner longitudinal beam 21. Specifically, the inner end of one border cross beam 22 is hinged to one end of the inner longitudinal beam 21, and the inner end of the other border cross beam 22 is hinged to the other end of the inner longitudinal beam 21; the outer ends of the two border cross beams 22 are detachably connected to an outer longitudinal beam 23 parallel to the inner longitudinal beam 21, and the two ends of the outer longitudinal beam 23 of the cross-frame assembly 2 are detachably connected to their respective outer columns 1. At least one, such as two or three, inner cross beams 24 of the cross-frame assembly 2 parallel to the border cross beams 22 are connected to the inner longitudinal beam 21 and the outer longitudinal beam 23, such as detachably connected. It is not difficult to understand that the inner longitudinal beam 21, the outer longitudinal beam 23, and the two border cross beams 22 form a rectangular frame. The border cross beam 22 and the inner longitudinal beam 21 are perpendicular to each other, that is, 90°, and the border cross beam 22 and the outer longitudinal beam 23 are also perpendicular to each other, that is, 90°. The shelf is also called a storage rack. The cross-frame assembly 2 can also be called a goods board assembly or a storage board assembly. The hinge is also called a pivot connection or a rotational connection. The so-called symmetry means the same structure and opposite directions, such as the groove of one is inward to the right and the groove of the other is to the left. The detachable connection is also called detachable fixation.

[0032] The outer longitudinal beam 23 is a first C-shaped steel pipe, and vertical clamping plates 231 are fixed at both ends. An inwardly convex vertical clamping block 2311 is fixed on the inner side of the vertical clamping plate 231, and the vertical clamping block 2311 is clamped from top to bottom in the wedge-shaped hole 111 of the outer column 1 that is larger at the top and smaller at the bottom. The outer end of the border cross beam 22 is accommodated in the groove, such as the first groove, of the first C-shaped steel pipe of the outer longitudinal beam 23, and a screw 25 passes through the screw through hole 233 of the first C-shaped steel pipe of the outer longitudinal beam 23 and is tightened in the threaded hole 2211 on the outer end plate 221 of the border cross beam 22.

[0033] The inner longitudinal beam 21 is a second C-shaped steel pipe, and the border cross beam 22 is a third C-shaped steel pipe whose one end can be accommodated in the second groove 211 of the second C-shaped steel pipe of the inner longitudinal beam 21. The so-called hinge uses a hollow rivet 26 for axial limitation, and the third C-shaped steel pipe of the border cross beam 22 can rotate relative to the second C-shaped steel pipe of the inner longitudinal beam 21 around the axis of the hollow rivet 26. Specifically, there are two rivet through holes on the two cross plates of the second C-shaped steel pipe of the inner longitudinal beam 21, and there are two rivet through holes on the two cross plates of the third C-shaped steel pipe of the border cross beam 22. After a hollow rivet 26 passes through the four rivet through holes from top to bottom, its free end, that is, the free end of the hollow rivet 26, is expanded into a large head for axial limitation.

[0034] The inner cross beam 24 is as Figure 3The fourth U-shaped steel pipe shown has the inner end of the fourth U-shaped steel pipe of the crossbeam 24 inside the frame placed in the groove of the second U-shaped steel pipe of the inner longitudinal beam 21, such as the second groove 211, and the outer end of the fourth U-shaped steel pipe of the crossbeam 24 inside the frame placed in the groove of the first U-shaped steel pipe of the outer longitudinal beam 23, such as the first groove; both ends of the fourth U-shaped steel pipe of the crossbeam 24 inside the frame and the first U-shaped steel pipe of the outer longitudinal beam 23 and the second U-shaped steel pipe of the inner crossbeam 21 are fixed by the first nylon expansion buckle 27.

[0035] It is not difficult to understand that the height dimension of the third U-shaped steel pipe of the frame crossbeam 22 is smaller than the height dimensions of the first U-shaped steel pipe of the outer longitudinal beam 23 and the second U-shaped steel pipe of the inner longitudinal beam 21, so that both ends of the third U-shaped steel pipe of the frame crossbeam 22 can be respectively placed in the groove of the first U-shaped steel pipe of the outer longitudinal beam 23, such as the first groove, and the groove of the second U-shaped steel pipe of the inner longitudinal beam 21, such as the second groove 211. The height dimension of the fourth U-shaped steel pipe of the crossbeam 24 inside the frame is smaller than the height dimensions of the first U-shaped steel pipe of the outer longitudinal beam 23 and the second U-shaped steel pipe of the inner longitudinal beam 21, so that both ends of the fourth U-shaped steel pipe of the crossbeam 24 inside the frame can be respectively placed in the groove of the first U-shaped steel pipe of the outer longitudinal beam 23, such as the first groove, and the groove of the second U-shaped steel pipe of the inner longitudinal beam 21, such as the second groove 211.

[0036] The inner longitudinal beam 21 can be fixed to the wall by screws. There are multiple screw through holes on the vertical plate of the second U-shaped steel pipe of the inner longitudinal beam 21, such as the second vertical plate 212, and the screw through holes are horizontally elongated through holes 2121. Here, multiple, such as a dozen, dozens, etc., can also be understood as several. It is not difficult to understand that the second vertical plate 212 of the second U-shaped steel pipe of the inner crossbeam 21 can be fixed to the wall by expansion screws or expansion bolts, or tightened to the wooden wall by ordinary screws.

[0037] The described shelf may further include a goods board supported on the inner longitudinal beam 21, the outer longitudinal beam 23, the frame crossbeam 22, and the crossbeam 24 inside the frame. That is, if the shelf is used to place goods with a relatively small bottom area, a goods board can be set. The goods board is also called a placing board or a partition board.

[0038] The pallet can be a cargo mesh panel 28 formed by welding a plurality of longitudinal round steel bars 281 and a plurality of transverse round steel bars 282. The cargo mesh panel 28 is placed on the inner longitudinal beam 21, the outer longitudinal beam 23, the frame cross beam 22 and the inner cross beam 24 inside the frame. Here, the plurality of longitudinal round steel bars 281 and the plurality of transverse round steel bars 282 can be several, more than a dozen or dozens, etc., and can also be understood as several. As described above, the inner longitudinal beam 21, the outer longitudinal beam 23 and the frame cross beam 22 are all U-shaped steel pipes. The two ends of the plurality of transverse round steel bars 282 are fixed to the upper cross plates of the U-shaped steel pipes of their respective inner longitudinal beams 21 and outer longitudinal beams 23 through nylon clamps 29 with two second nylon expansion buckles 291, or / and the two ends of the plurality of longitudinal round steel bars 281 are fixed to the upper cross plates of the third U-shaped steel pipes of their respective frame cross beams 22 through nylon clamps 29 with two second nylon expansion buckles 291. It is not difficult to understand that the nylon clamp 29 has a semi-circular groove for accommodating the round steel bar, and the nylon clamp 29 and the second nylon expansion buckle 291 can be integrally formed as a whole. The cargo mesh panel 28 can also be called a storage mesh panel. The nylon expansion buckle can also be called a nylon expansion screw. Plastic expansion buckles and plastic clamps can also be used.

[0039] The outer column 1 can be a rectangular steel pipe with a vertical through-notch in the middle of the lateral plate for the whole length. The upper-large and lower-small wedge-shaped holes 111 for engaging the vertical blocks 2311 of the vertical clamping plates 231 of the outer longitudinal beam 23 are arranged on the outer lateral plate 11 of the rectangular steel pipe of the outer column 1. There are two upper-large and lower-small wedge-shaped holes 111 in each row, and multiple in each column arranged at equal vertical intervals up and down. Here, the multiple in the vertical direction can be understood as more than a dozen or dozens, or understood as several. The vertical clamping plate 231 can be understood as a vertical clamping plate and can be an L-shaped clamping plate. One vertical plate of the L-shaped plate is used to fit and engage with the outer lateral plate 11 of the outer column 1, and the other vertical plate of the L-shaped plate is fixed to the end face of the outer longitudinal beam 23, such as by welding. And the vertical block 2311 can be understood as a vertical and inclined block here, such as Figure 4 and Figure 5 the vertical inclined block shown. The upper-large and lower-small wedge-shaped hole 111 can also be called an upper-large and lower-small triangular hole.

[0040] As Figure 1 shown, the cross-frame assemblies 2 can be multiple arranged vertically. Here, the multiple can be understood as several, such as two, three, four or five, etc. It is not difficult to understand that the structure of each cross-frame assembly 2 is the same. The inner longitudinal beam 21 of each cross-frame assembly 2 can be fixed to the wall, and both ends of the outer longitudinal beam 23 of each cross-frame assembly 2 can be detachably connected to the outer column 1.

[0041] As Figure 1As shown, there can be multiple transverse frame components 2 arranged horizontally. Here, "multiple" can be understood as several, such as two, three, four, five, etc. It is not difficult to understand that the structure of each transverse frame component 2 is the same. The inner longitudinal beam 21 of each transverse frame component 2 can be fixed to the wall, and both ends of the outer longitudinal beam 23 of each transverse frame component 2 can be detachably connected to the outer column 1.

[0042] Such as Figures 1 - 11 As shown, the installation process of this shelf is generally as follows:

[0043] First, determine the height of the inner longitudinal beam 21 on the wall according to the horizontal height at which the border crossbeam 22 is clamped on the outer column 1 supported on the ground, and then fix the inner longitudinal beam 21 hinged with two border crossbeams 22, such as by expansion screws, to the wall; then, engage the vertical locking blocks 2311 of the two vertical locking plates 231 of the outer longitudinal beam 23 into the wedge-shaped holes 111 of different sizes on the outer column 1 and make the connection firmly locked; then, unfold the two border crossbeams 22 until they are at a right angle to the inner longitudinal beam 21 and the outer longitudinal beam 23 and press the outer ends against the inner surface of the first groove of the first C-shaped steel pipe of the outer longitudinal beam 23, such as the first vertical plate 232 of the first groove, and then pass the respective screws 25 through the respective screw holes 233 on the first vertical plate 232 and tighten them into the threaded holes 2211 of the respective outer end plates 221 of the border crossbeam 22; then, insert the two ends of each of the multiple, such as two, frame inner crossbeams 24 or intermediate crossbeams, the fourth C-shaped steel pipes, into the grooves of the second C-shaped steel pipes of the inner longitudinal beam 21, such as the second groove 211, and the grooves of the first C-shaped steel pipes of the outer longitudinal beam 23, such as the first groove, and align the third expansion body holes 241 on the upper cross plates of each fourth C-shaped steel pipe with the second expansion body holes 213 on the upper cross plates of the second C-shaped steel pipes or the first expansion body holes 234 on the upper cross plates of the first C-shaped steel pipes, and then press the expansion bodies 271 of the first nylon expansion buckle 27 with the axial limiting ring 2711, central hole 2712, and multiple, such as four, vertical openings 2713, into the corresponding first expansion body holes 234 and third expansion body holes 241, and press them into the corresponding second expansion body holes 213 and third expansion body holes 241, and then press the nylon central column 272 with a large head of the first nylon expansion buckle 27 into the respective central holes 2712 to expand and tighten, so as to fix the outer longitudinal beam 23 and this end of the frame inner crossbeam 24, and fix this end of the inner longitudinal beam 21 and the frame inner crossbeam 24; then, place the goods mesh plate 28 formed by welding the longitudinal round steel 281 and the transverse round steel 282 on the inner longitudinal beam 21, outer longitudinal beam 23, two border crossbeams 22, and two frame inner crossbeams 24, and use multiple, such as Figure 3The four hoop fastenings shown in the figure: Pass the two second nylon expansion buckles 291 of the nylon hoop 29 holding the transverse round steel 282 through the two first buckle through holes 235 on the upper cross plate of the first C-shaped steel pipe of the outer longitudinal beam 23 and the two second buckle through holes 214 on the upper cross plate of the second C-shaped steel pipe of the inner longitudinal beam 21. At this time, the second nylon expansion buckle 291 with four vertical notches 2912 expands and tightens, and the radial conical ring 2911 at the bottom is axially limited to the bottom surface of the upper cross plate of the first C-shaped steel pipe and the bottom surface of the upper cross plate of the second C-shaped steel pipe, and presses the two ends of the transverse round steel 282. The second nylon expansion buckle 291 expands and tightens and is axially limited, so that the transverse round steel 282 is fixed to the inner longitudinal beam 21 and the outer longitudinal beam 23; Similarly: Or / and pass the two second nylon expansion buckles 291 of the nylon hoop 29 holding the longitudinal round steel 281 through the respective two buckle through holes on the upper cross plate of the third C-shaped steel pipe of the two side frame cross beams 22 and press the ends of the longitudinal round steel 281. The second nylon expansion buckle 291 expands and tightens and is axially limited, so that the longitudinal round steel 281 is fixed to the two side frame cross beams 22.

[0044] Both the first nylon expansion buckle 27 and the second nylon expansion buckle 291 can be called nylon expansion screws. The above-mentioned radial conical ring 2911 can also be called an axial limiting ring. The two terms vertical opening and vertical notch can be used interchangeably.

[0045] The above specific structure allows the following changes.

[0046] If it is specifically used to place goods with a large bottom area, the goods board can also be omitted and the goods can be directly placed on the side frame cross beams, inner frame cross beams, inner longitudinal beams and outer longitudinal beams. Multiple inner frame cross beams can be provided, such as three, four or five, etc. The spacing of the inner frame cross beams can be set according to the area of the placed goods to meet the needs of placing the goods.

[0047] The detachable connection between the side frame cross beam and the inner longitudinal beam and the outer longitudinal beam can also adopt the above-mentioned first nylon expansion buckle provided with multiple, such as four vertical notches, and can be connected without tools.

[0048] Such as Figure 1 shown:

[0049] Some cross-frame components, such as the goods mesh plates 28 in the middle of the transverse direction and the middle of the vertical direction, can also be replaced by a solid goods board 210, and are fixed by screw screwing or fixed by clamping with a nylon expansion buckle.

[0050] The width dimension of the cross-frame components is also allowed to be different according to actual needs. For example, the width of the upper cross-frame component in the middle of the transverse direction is narrower than the width of other cross-frame components.

[0051] A notch is also allowed to be left at a certain position of the shelf according to actual needs. For example, the cross-frame component is not installed at the installation position of the lower cross-frame component in the middle of the transverse direction.
