[0002] Screws are tools that use the physics and mathematical principles of the circular rotation of an object's inclined surface and friction to gradually fasten objects and machine parts. Screws are a general term for fasteners. Screws are an indispensable industrial necessity in daily life: such as very small screws used in cameras, glasses, clocks, electronics, etc.; general screws for televisions, electrical products, musical instruments, furniture, etc.; large screws and nuts are used in engineering, construction, and bridges; transportation equipment, airplanes, trams, cars, etc. use both large and small screws. Screws have important tasks in industry, and as long as there is industry on the earth, the function of screws will always be important. Screws are a common invention in people's production and life for thousands of years. In terms of application areas, it is the first invention of mankind.

[0003] However, when using the existing screw material box stacking rack, most of them need to manually lift the material box onto the stacking rack, and then push the material box to slide on the surface of the stacking rack to make it completely enter the surface of the stacking rack. In this process, the weight of the screws in the material box will increase the friction between the material box and the stacking rack, so that the workers need more force to completely push the material box into the surface of the stacking rack, which puts a burden on the workers' physical strength, thereby reducing the workers' work efficiency and making it still relatively inconvenient to use. Utility Model Content

[0033] Embodiment 1

[0034] See also Figure 1 - Fig.10 As shown in the figure, a practical screw material box stacking rack includes a main body 100, and a bottom beam 200 is fixedly connected to the outer wall of the main body 100. A support beam 300 is fixedly connected to the outer wall of the main body 100, and a support pipe 400 is fixedly connected to the outer wall of the support beam 300. The support pipe 400 can support the support beam 300 and ensure the stability of the material box 700 on the surface of the support beam 300. A cross beam 500 is fixedly connected to the outer wall of the main body 100, and a stiffening rib 600 is fixedly connected to the outer wall of the main body 100. The stiffening rib 600 can increase the structural rigidity of the stacking rack. The material box 700 is slidably connected to the outer wall of the bottom beam 200.

[0035] When in use, the material box 700 is first placed on the surface of the bottom beam 200 for storage. When there is no free space on the surface of the bottom beam 200, the remaining material boxes 700 can be placed on the surface of the support beam 300 for storage. At the same time, the support tube 400 can support the support beam 300, thereby ensuring the stability of the material box 700 on the surface of the support beam 300, and the stiffening rib 600 can increase the structural rigidity of the stacking rack, so that twice as many material boxes 700 can be placed in the same area, which greatly saves the reasonable utilization rate of the site, makes the site appear more tidy, and improves the overall usability of the stacking rack.

[0036] Embodiment 2

[0037] See also Figure 1 - Fig.10As shown in the figure, on the basis of the first embodiment, a sliding assembly 800 is assembled on the outer wall of the support beam 300, and the sliding assembly 800 includes a slide groove 801, and the slide groove 801 is opened on the surface of the support beam 300. A slider 802 is slidably connected to the outer wall of the support beam 300, and a ball 803 is rotatably connected to the inner wall of the slider 802, and the outer wall of the ball 803 is slidably connected to the slide groove 801. The ball 803 can reduce the friction between the slider 802 and the surface of the support beam 300, so that the slider 802 can slide more smoothly on the surface of the support beam 300. A pressing block 804 is slidably connected to the inner wall of the slider 802, a first spring 805 is fixedly connected to the outer wall of the pressing block 804, a clamping block 806 is fixedly connected to the outer wall of the bottom end of the pressing block 804, a first connecting gear 807 is rotatably connected to the inner wall of the support beam 300, a chain 808 is meshed on the outer wall of the first connecting gear 807, a second connecting gear 809 is meshed on the outer wall of one end of the chain 808, a first bevel gear 810 is fixedly connected to the outer wall of one end of the second connecting gear 809, a second bevel gear 811 is meshed on the outer wall of the first bevel gear 810, and a second bevel gear 812 is meshed on the outer wall of the second bevel gear 812. A connecting shaft 812 is fixedly connected to the outer wall of the gear 811, a second spring 813 is fixedly connected to the inner wall of one end of the connecting shaft 812, and a connecting block 814 is fixedly connected to the outer wall of the second spring 813. When the wheel 827 pushes out of the surface of the beam 500, the transmission block 824 will limit the rotation of the threaded rod 820. At this time, when the connecting shaft 812 rotates, the tooth groove 816 will squeeze the connecting block 814, so that the second spring 813 shrinks inwardly under the action of external force, thereby releasing the limitation on the connecting sleeve 815, so that the slider 802 can continue to slide without driving the connecting sleeve 815 to rotate. A connecting sleeve 815 is rotatably connected to the outer wall of one end of the connecting shaft 812, a tooth groove 816 is provided on the inner wall of the connecting sleeve 815, a connecting column 817 is fixedly connected to the outer wall of the connecting column 817, a crown gear 818 is fixedly connected to the outer wall of one end of the connecting column 817, a transmission gear 819 is meshed on the outer wall of the crown gear 818, a threaded rod 820 is fixedly connected to the outer wall of the transmission gear 819, a first transmission wheel 821 is fixedly connected to the outer wall of one end of the threaded rod 820, and a transmission belt 822 is rotatably connected to the outer wall of the first transmission wheel 821. A second transmission wheel 823 is rotatably connected to the outer wall of the transmission belt 822, a transmission block 824 is threadedly connected to the outer wall of the threaded rod 820, a connecting piece 825 is rotatably connected to the outer wall of the transmission block 824, a connecting plate 826 is rotatably connected to the outer wall of the connecting piece 825, and a wheel 827 is fixedly connected to the outer wall of the connecting plate 826. The material box 700 slides on the surface of the beam 500 via the wheel 827, which reduces the friction between the material box 700 and the beam 500, making the storage of the material box 700 more labor-saving and improving the overall usability of the device.

[0038] When in use, based on the first embodiment, when placing the material box 700 on the surface of the support beam 300, first place the bottom end of the material box 700 on the surface of the slider 802. When the weight of the material box 700 reaches a certain level, the material box 700 will press the pressing block 804, so that the pressing block 804 slides on the surface of the slider 802 and squeezes the first spring 805, so that the card block 806 is stuck in the inside of the chain 808, and then push the material box 700 to make the slider 802 slide on the surface of the support beam 300. When the slider 802 slides, it passes through the card block. The engagement of the block 806 with the chain 808 will drive the chain 808 to move, thereby driving the first connecting gear 807 and the second connecting gear 809 to rotate. When the second connecting gear 809 rotates, it can drive the first bevel gear 810 to rotate synchronously. Through the meshing between the first bevel gear 810 and the second bevel gear 811, when the first bevel gear 810 rotates, it will drive the second bevel gear 811 and the connecting shaft 812 to rotate. At the same time, through the engagement of the connecting block 814 with the tooth groove 816, the connecting sleeve 815, the connecting column 817 and the crown gear are The wheel 818 rotates synchronously with the connecting shaft 812. When the crown gear 818 rotates, it drives the transmission gear 819, the threaded rod 820 and the first transmission wheel 821 to rotate, and drives the second transmission wheel 823 to rotate through the transmission belt 822, so that the two sets of threaded rods 820 can rotate synchronously. Through the rotation of the threaded rod 820, the rotational motion of the transmission block 824 and the threaded rod 820 is converted into a linear motion of the transmission block 824 inside the support beam 300, so that the connecting member 825 rotates on the surface of the transmission block 824, and the connecting plate 82 6 is lifted up, thereby pushing the wheel 827 out of the surface of the support beam 300. When the wheel 827 pushes out of the surface of the cross beam 500, the transmission block 824 will limit the rotation of the threaded rod 820. At this time, when the connecting shaft 812 rotates, the tooth groove 816 will squeeze the connecting block 814, so that the second spring 813 is contracted inwardly under the action of external force. The material box 700 slides on the surface of the cross beam 500 through the wheel 827, reducing the friction between the material box 700 and the cross beam 500, making the storage of the material box 700 more labor-saving and improving the overall usability of the device.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
