Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1 - 3 and Figure 5 , the present utility model provides a technical solution: a combined material stacking rack, including a first bottom frame 1 and an adjusting mechanism 5. A second bottom frame 2 is provided on one side of the first bottom frame 1. A third bottom frame 13 and a fourth bottom frame 15 are provided above the first bottom frame 1 and the second bottom frame 2. The adjusting mechanism 5 is connected to both ends of the first bottom frame 1 and the second bottom frame 2. Trapezoidal frames 3 and connecting rods 4 are welded to both ends of the first bottom frame 1, the second bottom frame 2, the third bottom frame 13, and the fourth bottom frame 15, and the trapezoidal frames 3 and the connecting rods 4 are welded to each other.

[0027] Please refer to Figures 1 - 4 , one end of the adjusting mechanism 5 is located in the built-in groove of the first chassis 1. A transmission shaft 7 connected to the adjusting mechanism 5 is installed in the built-in groove of the first chassis 1 through a bearing. The adjusting mechanism 5 includes a lead screw 501, a first gear 502, a second gear 503, a handle 504, an outer rod 505 and an inner rod 506. Outer rods 505 are fixed at both ends of the first chassis 1 close to the second chassis 2. Inner rods 506 are fixed at both ends of the second chassis 2 close to the outer rods 505. The outer rod 505 and the inner rod 506 are slidably sleeved with each other. The lead screw 501 is installed in the inner part of the outer rod 505 through a bearing. The lead screw 501 and the inner rod 506 are threadedly sleeved with each other. One end of the lead screw 501 close to the built-in groove of the first chassis 1 is fixedly connected with the first gear 502. A second gear 503 is meshed and connected to one side of the first gear 502. The second gear 503 and the transmission shaft 7 are fixedly sleeved with each other. A handle 504 is fixed at one end of the transmission shaft 7. A first cross bar 6 and a second cross bar 9 are respectively welded on the adjacent sides of the first chassis 1 and the fourth chassis 15 and the second chassis 2 and the third chassis 13. Both ends of the third chassis 13 and the fourth chassis 15 are connected by a telescopic rod 14. The convex blocks at both ends of the inner rod 506 are slidably connected with the built-in grooves of the outer rod 505. The number of both the first gear 502 and the second gear 503 is two. The cross-sectional shapes of both the first cross bar 6 and the second cross bar 9 are triangular.

[0028] During specific implementation, since a combined material stacking rack is needed to support construction materials such as stacked pipes or steel bars when stacking construction materials, but the placement width of most combined material stacking racks is fixed. When more construction materials need to be stacked, the fixed placement width cannot meet the placement requirements of more materials, reducing the practicality of the combined material stacking rack. When adjusting the placement width of the combined material stacking rack, the handle 504 can be rotated to drive the second gear 503 and the transmission shaft 7 to rotate. The second gear 503 is meshed and connected with the first gear 502, so that the second gear 503 drives the first gear 502 to rotate. The first gear 502 then drives the lead screw 501 to rotate. The lead screw 501 and the inner rod 506 are threadedly meshed, so that the inner rod 506 moves to one side on the lead screw 501. At the same time, the inner rod 506 slides to one side inside the outer rod 505, so that the inner rod 506 drives the second chassis 2 to move. Subsequently, the second chassis 2 drives the third chassis 13 to move and pulls the telescopic rod 14 to extend. Finally, the second chassis 2 and the third chassis 13 drive the first cross bar 6 to move, and the placement width of the combined material stacking rack can be quickly adjusted. Then, construction materials such as steel bars or pipes are placed above the first cross bar 6 and the second cross bar 9. The adjusting mechanism 5 improves the practicality of the combined material stacking rack.

[0029] Please refer to Figure 1 、 Figure 2 and Figures 5 - 7 , a fixing block 11 is welded above the trapezoidal frame 3, docking blocks 12 are welded below both the third bottom frame 13 and the fourth bottom frame 15, a docking groove 10 is formed inside the fixing block 11 close to the docking block 12, and an installation mechanism 8 is connected to the inner sides of the docking block 12 and the fixing block 11. The installation mechanism 8 includes a screw 801, a limiting groove 802, a limiting block 803 and a return spring 804. The limiting block 803 and the return spring 804 are slidably connected in the built-in groove of the docking block 12, and the return spring 804 is located on one side of the limiting block 803. A limiting groove 802 is formed on the inner wall of the fixing block 11 close to the limiting block 803, and the screw 801 is threadedly penetrated through one side of the fixing block 11 close to the limiting groove 802. The cross-sectional shapes of the limiting block 803 and the limiting groove 802 are both trapezoidal.

[0030] During specific implementation, most of the combined material stacking racks are connected and installed between each layer rack through a plurality of bolts, and single disassembly is rather troublesome. When it is necessary to disassemble a single layer rack, the screw 801 can be rotated first to make the screw 801 engage with the fixing block 11 in a threaded manner, so that one end of the screw 801 pushes the limiting block 803 to one side. Subsequently, the limiting block 803 moves to one side and compresses the return spring 804 to contract. Finally, the third bottom frame 13 and the fourth bottom frame 15 are lifted upward, so that the third bottom frame 13 and the fourth bottom frame 15 drive the docking block 12 to move upward from the docking groove 10 of the fixing block 11, and the third bottom frame 13 and the fourth bottom frame 15 can be quickly disassembled from the trapezoidal frame 3 for separate use, improving the convenience of the combined material stacking rack.

[0031] Working principle: When using this combined material stacking rack, first adjust the placement width of the combined material stacking rack according to the placement requirements of the construction materials. The distance between the first bottom frame 1 and the second bottom frame 2 can be adjusted through the adjusting mechanism 5, and then the construction materials are placed above the first cross bar 6 and the second cross bar 9. When it is necessary to use a single layer rack of the combined material stacking rack alone, the third bottom frame 13 and the fourth bottom frame 15 can be disassembled from the trapezoidal frame 3 through the installation mechanism 8, improving the practicability and convenience of the combined material stacking rack. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
