Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] Please refer to Figures 1-3 This utility model provides a shelf for placing screws and panels, including a base 1, a screw placement mechanism and a panel placement mechanism; the screw placement mechanism and the panel placement mechanism are arranged side by side on one side of the base 1; the screw placement mechanism includes a first screw support 2 and a second screw support 3, and the panel placement mechanism includes a first panel support 4 and a second panel support 5;

[0037] The first screw bracket 2 and the second screw bracket 3 are respectively connected to the base 1, with the first screw bracket 2 located above the second screw bracket 3; the first screw bracket 2 and the second screw bracket 3 cooperate with each other to place the screw.

[0038] The first panel bracket 4 and the second panel bracket 5 are respectively connected to the base 1, with the first panel bracket 4 located above the second panel bracket 5; both the first panel bracket 4 and the second panel bracket 5 are used to place the panel.

[0039] The shelf for placing screws and panels includes a first screw support 2, a second screw support 3, a first panel support 4, and a second panel support 5. The first screw support 2 and the second screw support 3 can collect screws of various specifications and can also classify and place panels of different widths on the first panel support 4 and the second panel support 5. This achieves the purpose of centralized placement of panels and screws, occupies little space, and reduces the probability of panels and screws colliding with external objects, thus providing good protection.

[0040] Specifically, the first screw support 2 and the second screw support 3 have the same structure, including several screw support units;

[0041] The screw support unit includes a first horizontal part and a first support part; the first horizontal part is provided with a first placement gap 201, one end of the first support part is connected to the first horizontal part, and the other end of the first support part is connected to the base 1; one end of the first horizontal part is connected to the base 1, and the first horizontal part is horizontally arranged.

[0042] Several screw support units are arranged side by side, with a second placement gap 202 formed between adjacent screw support units; the first placement gap 201 on the first screw bracket 2 is located directly above the first placement gap 201 on the second screw bracket 3, and the second placement gap 202 on the first screw bracket 2 is located directly above the second placement gap 202 on the second screw bracket 3; the widths of the first placement gap 201 and the second placement gap 202 are the same, and the screw is located at the first placement gap 201 / second placement gap 202 of the second screw bracket 3;

[0043] Alternatively, the upper end of the screw is located near the first placement gap 201 / second placement gap 202 of the first screw support 2, and the middle part of the screw is located in the first placement gap 201 / second placement gap 202 of the second screw support 3.

[0044] Depending on their length, the screws can be placed in two ways: longer screws are fixed by engaging with the first placement gap 201 of the first screw bracket 2 and the first placement gap 201 of the second screw bracket 3; or they are fixed by engaging with the second placement gap 202 of the first screw bracket 2 and the second placement gap 202 of the second screw bracket 3. The upper end of the screw is located near the first placement gap 201 or the second placement gap 202 of the first screw bracket 2, while the middle part of the screw is located near the first placement gap 201 or the second placement gap 202 of the second screw bracket 3. Shorter screws are inserted into the first placement gap 201 or the second placement gap 202 of the second screw bracket 3.

[0045] The above structure can effectively concentrate the screw, taking up little space.

[0046] Specifically, the first horizontal part includes a first L-shaped plate 21 and a second L-shaped plate 22, and the first support part includes a first support plate 23 and a second support plate 24; the first support plate 23 and the second support plate 24 are arranged side by side; the first L-shaped plate 21 and the second L-shaped plate 22 are arranged along the width direction of the base 1.

[0047] The first L-shaped plate 21 and the second L-shaped plate 22 each include an integrally formed vertical plate 211 and a horizontal plate 212. The vertical plate 211 is vertically connected to one end of the bottom of the horizontal plate 212. One end of the first support plate 23 is connected to the bottom of the horizontal plate 212 of the first L-shaped plate 21, and the other end of the first support plate 23 is connected to the base 1. One end of the second support plate 24 is connected to the bottom of the horizontal plate 212 of the second L-shaped plate 22, and the other end of the second support plate 24 is connected to the base 1. The vertical plate 211 of the first L-shaped plate 21 abuts against the outside of the first support plate 23, and the vertical plate 211 of the second L-shaped plate 22 abuts against the outside of the second support plate 24.

[0048] The horizontal plate 212 of the first L-shaped plate 21 and the horizontal plate 212 of the second L-shaped plate 22 cooperate to form a first placement gap 201; the two adjacent vertical plates 211 cooperate to form a second placement gap 202.

[0049] The first horizontal section is formed by the cooperation of a first L-shaped plate 21 and a second L-shaped plate 22. A first support plate 23 is used to support the first L-shaped plate 21 and enhance its load-bearing capacity. A second support plate 24 is used to support the second support plate 24, and similarly, the second support plate 24 can enhance the load-bearing capacity of the first L-shaped plate 21. The first placement gap 201 is the same as the second placement gap 202, except that the first placement gap 201 is formed by the cooperation of the horizontal plate 212 of the first L-shaped plate 21 and the horizontal plate 212 of the second L-shaped plate 22, while the second placement gap 202 is formed by the cooperation of two adjacent vertical plates 211. Both can be used to restrict the movement of the screw, so that the screw can be uniformly and centrally placed on the shelf.

[0050] Furthermore, the first panel support 4 and the second panel support 5 have the same structure, including a plurality of panel support units 41, which are arranged side by side and cooperate to form a panel placement area, in which the panel is placed; a third placement gap 401 is formed between adjacent panel support units.

[0051] The panel support unit 41 includes a second horizontal portion 411 and a second support portion 412; the second horizontal portion 411 is provided with a fourth placement gap 402, one end of the second support portion 412 is connected to the second horizontal portion 411, and the other end of the second support portion 412 is connected to the base 1; one end of the second horizontal portion 411 is connected to the base 1, and the second horizontal portion 411 is horizontally arranged; the width of the third placement gap 401 is the same as that of the fourth placement gap 402.

[0052] Several second horizontal portions 411 cooperate to form a plane, which can be used to place a panel. The second support portion 412 is used to support the second horizontal portions 411.

[0053] Furthermore, the panel support unit 41 has the same structure as the screw support unit, and the gap between adjacent panel support units 41 is greater than the gap between adjacent screw support units.

[0054] The panel support unit 41 has the same structure as the screw support unit and is used to support the panel, so it will not be described in detail here. The gap between adjacent panel support units 41 is relatively large, which allows workers to move the panels using a forklift, reducing the workload of workers and improving handling efficiency.

[0055] Specifically, the second panel support 5 further includes a limiting angle iron member 51, which is detachably connected to the second panel support 5 and is arranged along the length direction of the base 1.

[0056] The limiting angle iron 51 is used to limit the width-direction movement of the panel within the panel placement area. Some panels are smaller than the panel placement area, resulting in a larger range of motion within the area. When the panel is placed closer to the connecting bracket 12, workers need to expend more physical effort to remove it. The above structure reduces the actual area of ​​the panel placement area, making the panel placement position more convenient for workers to remove, thus reducing their workload.

[0057] Specifically, the base 1 includes a bottom frame 11, a connecting bracket 12, and a support strip 13;

[0058] The connecting bracket 12 is vertically disposed on the top of the bottom frame 11, and the screw placement mechanism and the panel placement mechanism are disposed side by side on one side of the connecting bracket 12; the support bar 13 is obliquely disposed on the other side of the connecting bracket 12, and one end of the support bar 13 is connected to the top of the connecting bracket 12, and the other end is connected to the bottom frame 11.

[0059] The bottom frame 11 is provided with a panel placement area and a hollow area 101. The panel placement area is located directly below the vertical projection of the panel placement mechanism. The panel placement area is provided with a plurality of supporting angle iron pieces 102, which are spaced apart along the length of the bottom frame 11. The hollow area 101 is located directly below the vertical projection of the screw placement mechanism.

[0060] The connecting bracket 12 is used to fix the screw placement mechanism and the panel placement mechanism, while the base frame 11 provides support and stability. The support bar 13 is used to support the connecting bracket 12, preventing the connecting bracket 12 from deforming due to the excessive weight of the screws and panels placed on it, and helping to maintain the stability of the overall structure.

[0061] The bottom frame 11 has a panel placement area, which increases the number of panels that can be placed, allowing the shelf to hold more panels.

[0062] When the screw is placed in the screw placement mechanism, it is usually placed at an angle, with the upper end of the screw approaching one side of the connecting bracket 12, and the lower end of the screw abutting against the side wall of the hollow area 101 of the bottom frame 11, so that the screw can be stably placed on the screw placement mechanism.

[0063] The cross-section of the supporting angle iron 102 is L-shaped. One side of the supporting angle iron 102 in the horizontal direction is connected to the bottom frame 11, while the other side of the supporting angle iron 102 in the vertical direction is used to lift the panel, so as to prevent the panel from directly contacting the bottom frame 11, thereby reducing the possibility of the panel and the bottom frame 11 colliding. Moreover, there is a gap between adjacent supporting angle irons 102, which makes it easy for workers to remove the panel from the panel placement area.

[0064] Optionally, in one embodiment of the present invention, the base 1 further includes a first connecting plate 14, a second connecting plate 15, a third connecting plate 16, and a fourth connecting plate 17; the first screw bracket 2 is fixed to the first connecting plate 14, the second screw bracket 3 is fixed to the second connecting plate 15, the first panel bracket 4 is fixed to the third connecting plate 16, and the second panel bracket 5 is fixed to the fourth connecting plate 17.

[0065] The connecting bracket 12 is provided with two or more rows of connecting holes spaced apart along the length of the bottom frame 11. The connecting holes are spaced apart vertically by a number of connecting holes 120. The first connecting plate 14, the second connecting plate 15, the third connecting plate 16 and the fourth connecting plate 17 are detachably connected to the connecting bracket 12 through the connecting holes 120 and bolts.

[0066] During installation, by selecting the corresponding connection hole 120, the first connection plate 14, the second connection plate 15, the third connection plate 16 and the fourth connection plate 17 are bolted to the connection bracket 12, so that the screw placement mechanism and the panel placement mechanism are arranged side by side, and the first screw bracket 2 is located above the second screw bracket 3, and the first panel bracket 4 is located above the second panel bracket 5.

[0067] By adopting the above structure, the heights of the first screw bracket 2, the second screw bracket 3, the first panel bracket 4, and the second panel bracket 5 can be flexibly adjusted according to the actual dimensions of the screw and the panel. This allows for adjustment of the distances between the first screw bracket 2 and the second screw bracket 3, the distance between the second screw bracket 3 and the bottom frame 11, the distance between the first panel bracket 4 and the second panel bracket 5, and the distance between the second panel bracket 5 and the bottom frame 11. This facilitates the placement and removal of the screw and the panel by workers, preventing collisions between the screw or the panel and the first screw bracket 2, the second screw bracket 3, the first panel bracket 4, or the second panel bracket 5 due to size issues during placement and removal, thereby reducing the risk of damage or scratches to the screw or the panel.

[0068] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
