Description

Technical Field

[0001] This utility model relates to the field of transportation device technology, and in particular to a material box logistics transportation device with elastic buffer slots. Background Technology

[0002] Material handling boxes with elastic buffer slots are commonly used material transfer devices in logistics warehousing, production workshops, and other scenarios. They are primarily used to carry material boxes of various sizes, achieving efficient material transfer between different workstations and warehouse areas through the cooperation of movable and fixed mechanisms. Their core function is to reduce the intensity of manual handling, connect material storage, processing, and sorting processes, and reduce the risk of material damage during transportation through the buffer structure. They are widely used in industries such as electronics, machinery, food, and pharmaceuticals, and are particularly suitable for transporting small to medium-sized, easily damaged material boxes. However, existing material box logistics transportation devices have obvious shortcomings in actual use.

[0003] On the one hand, the clamping adaptability is poor and the fixation is not firm. The clamping structure of traditional devices is mostly designed with a fixed size, which cannot flexibly adjust the spacing according to the length and width of the material box. It can only adapt to a single specification of material box. When facing materials of different sizes, different transport devices need to be replaced, which not only increases the equipment purchase cost, but also reduces the logistics turnover efficiency. On the other hand, due to the lack of effective protection, if the traditional device encounters uneven ground or sudden turns during the transportation route, the material box is prone to collision with the inner wall of the device, causing damage. At the same time, most devices only focus on the load-bearing capacity of the bottom of the material box and lack protective structures for the sides, which further increases the risk of material tipping and collision, and cannot meet the transportation needs of high-precision materials. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a material box logistics transportation device with elastic buffer slot, which overcomes the shortcomings of the prior art and effectively solves the problems of poor clamping adaptability, unstable fixing and insufficient protection in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A material box logistics transportation device with elastic buffer slots includes a base plate. An adjustment mechanism is connected to one top end of the base plate. The adjustment mechanism includes a U-shaped plate, fixing blocks welded and fixed to the inner walls of both ends of the U-shaped plate, guide rods connected to the two fixing blocks, and a handle screw. A first clamping mechanism is welded and fixed to the other top end of the base plate, and a second clamping mechanism is welded and fixed to the top of the U-shaped plate. Both the first and second clamping mechanisms include a support plate, a bidirectional screw rod rotatably connected to the inner walls of both ends of the support plate, and clamping blocks screwed to both ends of the bidirectional screw rod. A protective mechanism connects the first and second clamping mechanisms. The protective mechanism includes a double-ended tube, connecting rods inserted into both ends of the double-ended tube, connecting blocks welded and fixed to the ends of the two connecting rods that are far apart from each other, and a plug rod welded and fixed to the bottom of the connecting blocks. Furthermore, casters are installed and fixed at all four corners of the bottom of the base plate, and a push handle is welded and fixed at one end of the top of the base plate.

[0006] The casters allow for flexible movement of the device, while the push handle makes it easy for operators to grip and push. Together, they enhance the device's ease of movement. Furthermore, each of the outer walls on both sides of the base plate is provided with a strip groove, and the two ends of the guide rod are welded and fixed to the inner walls of the two ends of one of the strip grooves, and the two ends of the handle screw are rotatably connected to the inner walls of the two ends of the other strip groove.

[0007] The slot provides mounting space for the guide rod and handle screw, ensuring stable operation of the adjustment mechanism components. Furthermore, the guide rod is slidably inserted into one of the fixing blocks, and the handle screw is screwed into the other fixing block.

[0008] When the handle screw is turned, the fixed block and U-shaped plate can be moved along the guide rod to adjust the position of the second clamping mechanism and adapt to material boxes of different lengths.

[0009] Furthermore, a groove is provided on one side of the outer wall of the support plate, and the two ends of the bidirectional lead screw are rotatably connected to the inner walls of the two ends of the groove, and the clamping block and the groove form a sliding fit.

[0010] When the bidirectional lead screw rotates, it can drive the clamping block to move closer or further away from the slide along the groove, thereby clamping and fixing material boxes of different widths. Furthermore, the middle part of the double-ended tube is a sealing structure, and a telescopic spring is provided between the sealing structure and the connecting rod. The top of the clamping block is provided with an insertion hole that matches the insertion rod.

[0011] The insertion rod and insertion hole cooperate to securely connect the protective mechanism to the first and second clamping mechanisms, forming side protection.

[0012] The beneficial effects of this utility model are as follows: Strong clamping adaptability and firm fixation: It effectively solves the problems of poor adaptability and unstable fixation of traditional devices. By adjusting the handle screw of the mechanism and the fixed block, rotating the handle screw can drive the U-shaped plate to move smoothly along the guide rod, thereby adjusting the distance between the second clamping mechanism and the first clamping mechanism, adapting to material boxes of different specifications without the need to replace the device. At the same time, when the bidirectional screws of the first and second clamping mechanisms rotate, they drive the clamping blocks to move closer synchronously along the slide. The slot on the top of the clamping block fits tightly against the side wall of the material box, achieving firm clamping from multiple directions. Excellent overall protection: It improves the insufficient protection of traditional devices. The plug at the bottom of the connecting block and the plug hole at the top of the clamping block are connected to the two clamping mechanisms to form a protective mechanism that surrounds the side of the material box, effectively preventing the material box from tipping over and further improving transportation safety.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0016] Reference Figure 1-4A material box logistics transportation device with elastic buffer slots includes a base plate 1. An adjustment mechanism 4 is connected to one top end of the base plate 1. The adjustment mechanism 4 includes a U-shaped plate 5, fixing blocks 6 welded and fixed to the inner walls of both ends of the U-shaped plate 5, guide rods 7 and handle screws 8 connected to the two fixing blocks 6 respectively. A first clamping mechanism 9 is welded and fixed to the other top end of the base plate 1, and a second clamping mechanism 10 is welded and fixed to the top of the U-shaped plate 5. Both the first clamping mechanism 9 and the second clamping mechanism 10 include a support plate 11, a bidirectional screw 12 rotatably connected to the inner walls of both ends of the support plate 11, and clamping blocks 13 screwed to both ends of the bidirectional screw 12. A protective mechanism 14 is connected between the first clamping mechanism 9 and the second clamping mechanism 10. The protective mechanism 14 includes a double-ended tube 15, connecting rods 16 inserted into both ends of the double-ended tube 15, connecting blocks 17 welded and fixed to the ends of the two connecting rods 16 that are far apart from each other, and a plug rod 18 welded and fixed to the bottom of the connecting block 17. Universal casters 2 are fixedly installed at the four corners of the bottom of the base plate 1, and a push handle 3 is welded to one end of the top of the base plate 1. The universal casters 2 facilitate flexible movement of the device, and the push handle 3 is easy for the operator to grip and push. The combination of the two enhances the ease of movement of the device. One end of each side outer wall of the base plate 1 is provided with a strip groove, and the two ends of the guide rod 7 are welded to the inner wall of one of the strip grooves. The two ends of the handle screw 8 are rotatably connected to the inner wall of the other strip groove. The strip groove provides installation space for the guide rod 7 and the handle screw 8, ensuring the stable operation of the components of the adjustment mechanism 4. The guide rod 7 is inserted and slidably connected to one of the fixing blocks 6, and the handle screw 8 is screwed to the other fixing block 6. When the handle screw 8 is rotated, it can drive the fixing block 6. Block 6 and U-shaped plate 5 move along guide rod 7 to adjust the position of second clamping mechanism 10 to adapt to material boxes of different lengths. A sliding groove is opened on one side of the outer wall of support plate 11, and the two ends of bidirectional screw 12 are rotatably connected to the inner walls of the two ends of the sliding groove. Clamping block 13 forms a sliding fit with the sliding groove. When bidirectional screw 12 rotates, it can drive clamping block 13 to move closer or further away from the sliding groove synchronously, so as to clamp and fix material boxes of different widths. The middle part of the double-ended tube 15 is a sealing structure, and a telescopic spring is provided between the sealing structure and the connecting rod 16. The top of clamping block 13 is opened with a socket adapted to the insertion rod 18. The insertion rod 18 cooperates with the socket to make the protective mechanism 14 stably connect the first and second clamping mechanisms to form side protection. For the base plate and mobile foundation: Base plate 1 is made of cold-rolled steel plate with a thickness of 8-10mm (size 600×400mm), and the surface is treated with electrostatic spraying (coating thickness 60-80μm), which has strong corrosion resistance and can be used for a long time in humid workshops or warehouses without easily rusting. The four corners of the bottom of base plate 1 are fixed with casters 2 by M8×20 bolts. Casters 2 are made of polyurethane wheels with braking function (wheel diameter 80mm), with a Shore A85 hardness, which has wear-resistant and quiet characteristics, and the pushing resistance is ≤40N, which can be driven by a single person. Easy to push; when braking, the wheel axle is locked by stepping on the brake pedal, and the braking friction force is ≥180N, ensuring that the device does not slip when loading or unloading materials or when stopping, avoiding accidental movement. The push handle 3 is welded and fixed at one end of the top of the base plate 1. The push handle 3 is a 304 stainless steel round tube with a diameter of 20mm, bent into a U-shape (height 900mm, spacing 300mm), and the surface is covered with a 3mm thick EVA anti-slip sleeve. The surface of the anti-slip sleeve has a diamond pattern (friction coefficient ≥0.6), which makes it less likely for operators to slip and get tired after holding it for a long time, improving the comfort of operation. For the adjustment mechanism: The U-shaped plate 5 of the adjustment mechanism 4 is formed by bending a 5mm thick steel plate (opening width 100mm, length 300mm). The fixing blocks 6 welded to the inner walls at both ends are rectangular steel plates (dimensions 50×30×10mm). The two fixing blocks 6 correspond to the guide rod 7 and the handle screw 8 respectively. The welded joints are ground smooth (roughness Ra≤6.3μm) to ensure a firm connection without any false welds. The strip grooves on one end of the outer walls on both sides of the base plate 1 are rectangular grooves with a width of 20mm and a depth of 15mm. The guide rod 7 is a 304 stainless steel round rod with a diameter of 12mm. Both ends are fully welded to the inner walls of one of the strip grooves (weld leg height 4mm). The surface is polished. (Roughness Ra≤0.8μm), forming a precise sliding fit with the insertion hole (diameter 12.1mm) of the fixing block 6, without obvious jamming, ensuring smooth movement of the U-shaped plate 5. The handle screw 8 is a trapezoidal thread screw with a diameter of 12mm (pitch 4mm, accuracy 7H), and both ends are rotatably connected to the inner walls of the two ends of another strip groove through deep groove ball bearings (model 6202). The radial clearance of the bearing is ≤0.012mm to reduce rotational friction. One end of the handle screw 8 extends to the outside of the base plate 1 and is welded to a plastic handle (surface knurled treatment) with a diameter of 30mm. The rotational torque is ≤15N・m, and the operator can easily adjust the position of the U-shaped plate 5 with one hand without the need for tools. For the clamping mechanism: The support plate 11 of the first clamping mechanism 9 is a rectangular steel plate (300×150mm) with a thickness of 6mm. The bottom is fully welded to the top of the base plate 1. The weld is inspected to ensure there are no welding defects. The verticality deviation of the support plate 11 is ≤0.1mm / m to prevent the material box from tilting during clamping. The support plate 11 of the second clamping mechanism 10 is fully welded to the top of the U-shaped plate 5 and is parallel to the support plate 11 of the first clamping mechanism to ensure that the material box is subjected to uniform force during clamping. The groove on one side of the outer wall of the support plate 11 is a T-shaped groove with a width of 25mm and a depth of 10mm. The double-acting screw 12 is a trapezoidal threaded screw with a diameter of 10mm (the threads at both ends turn in opposite directions and the pitch is 3mm). Both ends are fixed to the inner walls of the groove by thrust ball bearings (model 51102). It can withstand the axial force during clamping (maximum axial force 200N) to prevent the double-acting screw 12 from axially shifting. The clamping block 13 is an L-shaped steel plate (80×50×5mm). The top has a 15mm deep and 10mm wide slot (suitable for material box side wall thickness of 3-8mm). A 2mm thick silicone pad (Shore hardness 50) is pasted on the inner wall of the slot. The silicone pad is elastic and can fit tightly against the side wall of the material box while avoiding scratching the powder coating layer on the surface of the material box. The T-shaped slider at the bottom of the clamping block 13 slides in conjunction with the slide groove (gap 0.1-0.2mm). When the bidirectional screw 12 rotates, the two clamping blocks 13 at both ends move closer or further away along the slide groove. The clamping stroke is 50-200mm, which is suitable for material boxes with a width of 80-300mm and meets the clamping needs of most small and medium-sized material boxes. One end of the bidirectional screw 12 extends to the outside of the support plate 11 and is welded to a 25mm diameter adjustment knob (knurled surface) for easy adjustment by the operator. A single person can complete the clamping or unlocking operation within 30 seconds. For the protective mechanism: the double-ended tube 15 of the protective mechanism 14 is a PVC pipe with a diameter of 25mm (length 200mm), which is lightweight and impact-resistant. A circular sealing plate (thickness 3mm) is welded to the middle of the tube. Telescopic springs (wire diameter 2mm, free length 50mm, stiffness coefficient 10N / mm) are installed on both sides of the sealing plate. One end of the telescopic spring is welded to the sealing plate, and the other end is welded to the connecting rod 16 to ensure that the spring does not fall off during extension and retraction. The connecting rod 16 is a stainless steel round rod with a diameter of 18mm (length 120mm). One end is inserted into the double-ended tube 15 (fitting clearance 0.5mm), and it can slide axially along the double-ended tube 15 with a sliding stroke of 10-15mm. During transport bumps, the telescopic spring... The spring absorbs impact force through compression or tension to achieve elastic buffering. The connecting block 17 is a rectangular steel plate (40×30×5mm). The bottom-welded insertion rod 18 is a stainless steel round rod with a diameter of 8mm and a length of 20mm. The insertion rod 18 is inserted into the insertion hole (8.1mm diameter) on the top of the clamping block 13. The insertion and extraction force is ≤15N. The operator can quickly install or remove the protective mechanism 14 without tools. Each set of devices is equipped with 2-4 protective mechanisms 14. The number of installations can be selected according to the height of the material box (100-300mm). For example, a material box with a height of 200mm can be equipped with 2 protective mechanisms (located in the middle and top of the material box respectively) to form comprehensive side protection and prevent the material box from tipping over.

[0017] Working principle: Adjusting the clamping distance to fit the material box: First, determine the distance between the first clamping mechanism 9 and the second clamping mechanism 10 according to the length of the material box to be transported. The operator holds the plastic handle of the adjusting mechanism 4 and turns the handle screw 8 clockwise or counterclockwise. Since the handle screw 8 is screwed to the fixing block 6 at one end of the U-shaped plate 5, and the fixing block 6 at the other end of the U-shaped plate 5 is slidably engaged with the guide rod 7, the U-shaped plate 5 moves smoothly along the guide rod 7 when the handle screw 8 is turned, thereby adjusting the position of the second clamping mechanism 10. When the distance between the two clamping mechanisms is slightly greater than the length of the material box (leaving 5-10mm installation space), stop turning the handle screw 8 to complete the distance adjustment and adapt to material boxes of different lengths. Place and clamp the material box: Place the material box stably at the center of the top of the base plate 1, so that one end of the material box is attached to the clamping block 13 of the first clamping mechanism 9 and the other end is aligned with the clamping block 13 of the second clamping mechanism 10. Then, the operator turns the adjustment knobs of the two clamping mechanisms respectively, which drives the bidirectional lead screw 12 to rotate. Since the threads at both ends of the bidirectional lead screw 12 turn in opposite directions and the clamping block 13 slides with the slide groove, when the bidirectional lead screw 12 rotates, it drives the clamping blocks 13 at both ends to move closer to the material box along the slide groove. The slots at the top of the clamping blocks 13 gradually fit against the side wall of the material box. Continue to turn the adjustment knob until the clamping blocks 13 are in close contact with the side wall of the material box (clamping force 50-80N). Stop rotating. At this time, the material box is firmly clamped by the clamping blocks 13 at both ends without loosening or displacement, ensuring stable position during transportation. Install the protective mechanism and start transportation: Select 2-4 protective mechanisms 14 according to the height of the material box. Align the bottom insert rod 18 of the connecting block 17 of each protective mechanism 14 with the insertion hole at the top of the clamping block 13, and insert it forcefully until the insert rod 18 is fully inserted into the insertion hole, so that the protective mechanism 14 is firmly connected to the clamping block 13 of the first and second clamping mechanisms, forming a surrounding protection for the side of the material box. The operator holds the push handle 3, releases the brake of the universal wheel 2, and pushes the device to move along the preset transportation path. During transportation, if the ground is bumpy or there is a sudden stop, the material box will shake slightly. At this time, the telescopic spring of the protective mechanism 14 will be compressed or stretched with the shaking, absorbing the impact force of the material box, reducing the hard collision between the material box and the clamping block 13, and protecting the material from damage. At the same time, the connecting rod 16 of the protective mechanism 14 cooperates with the double-ended tube 15 to limit the lateral displacement of the material box and effectively prevent the material box from tipping over. Unloading and Device Reset: After the device is transported to the target location, depress the brake pedal locking device of the universal wheel 2 to prevent the device from sliding. First, pull out the plug rod 18 of the protective mechanism 14 and disassemble all protective mechanisms. Then, rotate the adjustment knobs of the two clamping mechanisms in the opposite direction to drive the bidirectional screw 12 to rotate in the opposite direction, so that the clamping block 13 moves away from the material box along the slide groove and releases the clamping fixation. Finally, manually remove the material box from the base plate 1 to complete the unloading. If other sizes of material boxes need to be transported, repeat the above steps of "adjusting the spacing - clamping fixation - installing protection - transporting". There is no need to replace the device. The operation is convenient, highly adaptable, and effectively improves the efficiency of logistics transportation.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
