Description

Technical Field

[0001] The invention relates to the field of cargo transportation fixation, and in particular to a protection device used for logistics transportation. Background Art

[0002] Protecting goods can effectively prevent various external factors during transportation, such as collision, vibration, friction, etc., to avoid damage, deformation or loss of goods, while ensuring safety during transportation.

[0003] During transportation, when placing goods of different sizes in the carriage, it is often necessary to manually adjust the position of the goods and use different tools to fix them. Especially when the height of the goods is inconsistent or the bottom is irregular, fixation becomes very difficult. For example, goods with uneven bottoms cannot provide a uniform contact surface, and traditional fixing methods often cannot ensure firmness, causing the goods to easily slide or tilt during transportation. At the same time, taller goods require additional support, while short goods may move due to insufficient fixation; manual fixation is not only inefficient and time-consuming, but also prone to errors during operation, resulting in damage to the goods or increasing the risk during transportation, thus affecting the overall transportation safety. Summary of the invention

[0004] In order to overcome the disadvantage that during transportation, goods of different sizes often need to be manually adjusted and fixed with tools, especially when the bottom is irregular or the height is different, which can easily lead to loose fixation, sliding, tilting or displacement of goods, and increase transportation risks. The technical problem is: to provide a protective device for logistics transportation, which can automatically adjust and fix goods, solve the difficulties of manual adjustment and tool fixation, especially when facing goods of different heights or irregular bottoms, and reduce the risk of damage to goods.

[0005] The technical solution is: a protective device for logistics transportation, including a carriage, one side of the carriage is open, two doors are provided at the open part of the carriage, an outer shell is covered on the carriage, a chamber is formed between the outer side of the carriage and the inner side of the outer shell, a pressing mechanism for compacting the goods is provided on the outer shell, a locking mechanism is provided on the pressing mechanism, and the locking mechanism is used to lock the pressing mechanism.

[0006] Furthermore, the pressing mechanism includes connecting blocks, six groups of connecting blocks are evenly spaced and installed on two opposite sides of the car, with a total of twelve groups of connecting blocks, each group of connecting blocks consists of two connecting blocks, a rotating shaft is rotatably provided between the two connecting blocks of each group, with a total of twelve rotating shafts, a lower pressing plate is fixedly installed in the middle of each rotating shaft, with a total of twelve lower pressing plates, and the sides of the twelve lower pressing plates away from each other respectively pass through two opposite sides of the car, six sliding frames are evenly spaced and slidably provided on two opposite sides outside the car, with a total of twelve sliding frames, a roller is rotatably provided on the upper part of each sliding frame, each roller is respectively in contact with one side of each lower pressing plate, six electric push rods are evenly spaced and installed on two opposite sides outside the car, with a total of twelve electric push rods, and the telescopic rod of each electric push rod is fixedly connected to the bottom of each sliding frame.

[0007] Furthermore, the locking mechanism includes a threaded rod, each connecting block is connected to a threaded rod by a thread, and there are a total of twenty-four threaded rods. A friction block is rotatably provided at the ends of the twenty-four threaded rods that are close to each other, and each friction block is slidably connected to each connecting block. A gear is installed at the ends of the twenty-four threaded rods that are away from each other, and a rack is installed on the side of each sliding frame that is away from each other. Each rack is located under each gear, and the rack will engage with the gear after moving.

[0008] Furthermore, the width of the rack is greater than the width of the gear.

[0009] Furthermore, a circle of spline grooves is formed at both ends of each rotating shaft, and a side of each friction block close to the rotating shaft is provided with a rough arc surface, and the rough arc surface on the friction block fits with the curved surface on the rotating shaft.

[0010] Furthermore, it also includes a limiting mechanism arranged on the car body, which is used to limit the cargo, and the limiting mechanism includes a sleeve plate, a sleeve plate is slidably provided at the lower part of the car body, six connecting frames are evenly spaced on both sides of the sleeve plate, and there are twelve connecting frames in total, each connecting frame is provided with a bending portion on the top, and the bending portion on each connecting frame is respectively located in each sliding frame, forty movable bars are slidably provided on the sleeve plate, each movable bar is connected to the bottom of the sleeve plate by two springs, and each movable bar slides through the bottom of the car body.

[0011] Furthermore, it also includes rollers, and two rollers are rotatably arranged on the upper part of each movable bar.

[0012] Furthermore, a rubber sleeve is included, and a rubber sleeve is installed on each side of the twelve lower pressing plates that are close to each other.

[0013] Furthermore, it also includes a stop block, each sliding frame is equipped with a stop block, and the lower part of each stop block is in contact with the top of the bent part of each connecting frame.

[0014] The beneficial effects are: 1. The twelve lower pressure plates respectively contact the tops of goods at different heights, so that they can adapt to goods at different heights. The rough arc surfaces on the twenty-four friction blocks contact the twenty-four spline grooves on the twelve rotating shafts, so that the lower pressure plate can be fixed.

[0015] 2. The movable bar that enters into the gaps between the goods can relatively perfectly fix the goods placed in different positions and of different sizes in the car, avoiding displacement of the goods during sudden braking, uphill and downhill driving, and further protecting the goods of different sizes to avoid damage to the goods caused by collisions between the goods. At the same time, through the adaptive design of the movable bar, it can automatically adjust when the shape and size of the goods change, and can provide a better fixing surface for goods with uneven bottoms, thereby maintaining the best fixing effect, enhancing the adaptability of the goods during transportation, avoiding damage or displacement of the goods caused by external forces, and ensuring safety and stability during transportation.

[0016] 3. When the movable bar moves, it drives the roller to rotate, reducing friction and preventing damage to the side of the goods; the lower pressure plate increases friction through the rubber sleeve to protect the top of the goods; when the sliding frame is reset, it drives the block to push the connecting frame to reset, ensuring that the sleeve and the movable bar are accurately reset to avoid the unreset movable bar from jamming the goods, thereby effectively reducing damage during transportation.

DETAILED DESCRIPTION

[0033] The preferred technical solutions of the present invention are described in detail below with reference to the accompanying drawings.

[0034] Embodiment 1: A protective device for logistics transportation, such as Figure 1-15 As shown, it includes a carriage 1, one side of the carriage 1 is open, and two doors 2 are provided at the open part of the carriage 1 through hinges. A shell 3 is sleeved on the carriage 1, and a chamber is formed between the outer side of the carriage 1 and the inner side of the shell 3. A pressing mechanism for pressing the goods is provided on the shell 3, and a locking mechanism is provided on the pressing mechanism, and the locking mechanism is used to lock the pressing mechanism.

[0035] The pressing mechanism includes a connecting block 41. Six groups of connecting blocks 41 are evenly spaced and installed on two opposite sides of the carriage 1. There are twelve groups of connecting blocks 41 in total. Each group of connecting blocks 41 is composed of two connecting blocks 41. A rotating shaft 42 is rotatably provided between the two connecting blocks 41 of each group through a bearing. There are twelve rotating shafts 42 in total. A pressing plate 43 for self-adapting the height of the cargo is fixedly installed in the middle of each rotating shaft 42. There are twelve pressing plates 43 in total. The sides of the twelve pressing plates 43 that are away from each other pass through two opposite sides of the carriage 1, respectively. On the side, six sliding frames 44 are evenly spaced and slidably provided on two opposite sides outside the carriage 1. The sliding frames 44 will slide up and down along the carriage 1. There are a total of twelve sliding frames 44. A roller 45 is rotatably provided on the upper part of each sliding frame 44. Each roller 45 is respectively in contact with one side of each lower pressure plate 43. Six electric push rods 46 are evenly spaced and installed by bolts on two opposite sides outside the carriage 1. There are a total of twelve electric push rods 46. The telescopic rod of each electric push rod 46 is fixedly connected to the bottom of each sliding frame 44.

[0036] The locking mechanism includes a threaded rod 51, and each connecting block 41 is connected to a threaded rod 51 by a thread. There are a total of twenty-four threaded rods 51. The ends of the twenty-four threaded rods 51 that are close to each other are provided with a friction block 52 by a bearing rotation. Each friction block 52 is slidably connected to each connecting block 41. The ends of the twenty-four threaded rods 51 that are away from each other are equipped with a gear 53. The side of each sliding frame 44 that is away from each other is equipped with a rack 54. Each rack 54 is located below each gear 53, and the rack 54 will mesh with the gear 53 after moving.

[0037] The width of the rack 54 is greater than the width of the gear 53 .

[0038] A circle of spline grooves is formed at both ends of each rotating shaft 42 . A side of each friction block 52 close to the rotating shaft 42 is provided with a rough arc surface, and the rough arc surface on the friction block 52 fits with the curved surface on the rotating shaft 42 .

[0039] After the operator opens the two compartment doors 2, he puts the cargo into the compartment 1, and then the operator starts the extension of the telescopic rods of the twelve electric push rods 46, which drive the twelve sliding frames 44, the twelve rollers 45 and the twenty-four racks 54 to move upward. When the twelve rollers 45 are separated from one side of the twelve lower pressure plates 43, the side of the twelve lower pressure plates 43 that are close to each other will swing downward, and the side of the twelve lower pressure plates 43 that are away from each other will swing upward. After the side of the twelve lower pressure plates 43 that are close to each other swings downward and contacts the top of the cargo, the twelve lower pressure plates 43 stop swinging, and the twelve sliding frames 44 drive the twenty-four racks 54 to continue to move upward. When the twenty-four racks 54 are meshed with the twenty-four gears 53, the twenty-four racks 54 and the twenty-four gears 53 rotate, and the twenty-four gears 53 drive the twenty-four threaded rods 51 to rotate, and the twenty-four threaded rods 51 move in a direction close to each other. While the twenty-four gears 53 rotate, The fourteen racks 54 slide, and the twenty-four threaded rods 51 drive the twenty-four friction blocks 52 to move in the direction of approaching each other. After the rough arc surfaces on the twenty-four friction blocks 52 contact with the twenty-four spline grooves on the twelve rotating shafts 42, the twenty-four friction blocks 52 can fix the twelve rotating shafts 42 and the twelve lower pressure plates 43. Then the operator closes the two compartment doors 2, and the twelve lower pressure plates 43 contact the tops of the goods at different heights respectively, so that the goods at different heights can be adaptively adjusted. The rough arc surfaces on the twenty-four friction blocks 52 contact with the twenty-four spline grooves on the twelve rotating shafts 42, so that the lower pressure plates 43 can be fixed. During transportation, the goods at different heights can be better fixed. At the same time, the close cooperation between the friction blocks 52 and the spline grooves ensures that the lower pressure plates 43 will not shift or loosen during transportation, and can always maintain the best fixing effect under different cargo conditions, effectively improving the stability and safety of the goods.After the cargo is transported to the designated location, the operator first starts to shorten the telescopic rods of the twelve electric push rods 46, and the telescopic rods of the electric push rods 46 drive the twelve sliding frames 44, the twelve rollers 45 and the twenty-four racks 54 to move downward, and the twenty-four racks 54 drive the twenty-four gears 53 to rotate in the opposite direction, and the twenty-four gears 53 drive the twenty-four threaded rods 51 to rotate in the opposite direction, and the twenty-four threaded rods 51 move away from each other, and the twenty-four gears 53 rotate in the opposite direction while sliding on the twenty-four racks 54, and the twenty-four threaded rods 51 drive the twenty-four gears 53 to rotate in the opposite direction. The four friction blocks 52 move away from each other, and the rough arc surfaces on the twenty-four friction blocks 52 separate from the twenty-four spline grooves on the twelve rotating shafts 42. When the twelve rollers 45 contact one side of the twelve lower pressing plates 43, the twelve rollers 45 drive the side of the twelve lower pressing plates 43 away from each other to swing downward, and the side of the twelve lower pressing plates 43 close to each other to swing upward. The side of the twelve lower pressing plates 43 close to each other swings upward and separates from the top of the cargo. Then the operator opens the two compartment doors 2 and takes the cargo out of the compartment 1. ;

[0040] Embodiment 2: Based on embodiment 1, Figure 4-Figure 10 As shown, there is also a limiting mechanism arranged on the carriage 1, which is used to limit the cargo. The limiting mechanism includes a sleeve 61. A sleeve 61 is slidably provided at the lower part of the carriage 1, and the sleeve 61 will slide up and down along the carriage 1. Six connecting frames 62 are evenly spaced on both sides of the sleeve 61, and there are twelve connecting frames 62 in total. A bending portion is provided on the top of each connecting frame 62, and the bending portion on each connecting frame 62 is respectively located in each sliding frame 44. Forty movable bars 63 are slidably provided on the sleeve 61, and each movable bar 63 is connected to the bottom of the sleeve 61 by two springs 64, and each movable bar 63 slides through the bottom of the carriage 1.

[0041] After the goods are put into the carriage 1, there are gaps between the goods. When the twelve sliding frames 44 move upward and touch the bottom of the bent parts of the twelve connecting frames 62, the twelve sliding frames 44 will drive the twelve connecting frames 62 to move upward, and the twelve connecting frames 62 will drive the sleeve 61, forty movable bars 63 and springs 64 to move upward. After a part of the movable bars 63 moves upward and touches the bottom of the goods, this part of the movable bars 63 will no longer move upward, and the springs 64 will stretch, thereby providing a uniform contact surface for the goods with uneven bottoms, and the other part of the movable bars 63 moves upward into the gaps left between the goods. The movable bar 63 entering into the gaps between the cargoes can relatively perfectly fix cargoes placed at different positions and of different sizes in the carriage 1, thereby avoiding displacement of cargoes during sudden braking or uphill and downhill driving, and further protecting cargoes of different sizes, thereby avoiding damage to the cargoes caused by collisions between the cargoes. At the same time, through the adaptive design of the movable bar 63, it can automatically adjust when the shape and size of the cargoes change, thereby maintaining the best fixing effect, enhancing the adaptability of the cargoes during transportation, avoiding damage or displacement of the cargoes due to external forces, and ensuring safety and stability during transportation.

[0042] Embodiment 3: Based on embodiment 2, Figure 6-Figure 15 As shown, rollers 7 are also included, and two rollers 7 are rotatably provided on the upper part of each movable bar 63.

[0043] A rubber sleeve 8 is also included. A rubber sleeve 8 is detachably mounted on each of the two sides of the twelve lower pressing plates 43 that are close to each other.

[0044] A stop block 9 is also included. Each sliding frame 44 is equipped with a stop block 9. The lower portion of each stop block 9 contacts the top of the bent portion of each connecting frame 62.

[0045] When the movable bar 63 moves, the roller 7 is driven to move. When the roller 7 contacts the two sides of the goods, the roller 7 can rotate, thereby reducing the friction force, making the movable bar 63 move more smoothly, and also avoiding damage to the side of the goods.

[0046] When the lower pressing plate 43 swings, the rubber sleeve 8 is driven to swing, and the rubber sleeve 8 contacts the top of the cargo, thereby increasing the friction force and protecting the top of the cargo from damage.

[0047] When the sliding frame 44 moves downward to reset, it will drive the stop block 9 to move downward. After the stop block 9 contacts the top of the bending part of the twelve connecting frames 62, the stop block 9 will push the twelve connecting frames 62 to move downward to reset, thereby driving the sleeve plate 61 and the forty movable bars 63 to move and reset accurately.
