Description

Technical Field

[0001] This utility model relates to the field of cargo anti-deviation technology, specifically to a multi-dimensional cargo anti-deviation fixing device. Background Technology

[0002] Cargo anti-deviation fixing devices are auxiliary equipment or structural components used in all logistics processes such as cargo transportation, handling, and warehousing. They can counteract the impact of external forces on cargo through physical constraints such as clamping, supporting, limiting, and binding, thereby limiting unnecessary displacement, deviation, or tipping of cargo, maintaining the stability of cargo, reducing logistics losses, and improving the overall efficiency of logistics operations.

[0003] However, many existing multi-dimensional cargo anti-deviation fixing devices have small internal spaces, and the horizontal and vertical clamping is set in different positions, resulting in low space utilization. They also lack shock absorption and easy handling features. When the device body is hit, the cargo inside will vibrate, reducing the clamping tightness and making it prone to wear.

[0004] This invention can effectively fix and clamp goods of different lengths, widths and heights, improve the space utilization of the clamping mechanism, and also has the characteristics of shock absorption and easy handling, which has certain practicality. Utility Model Content

[0008] Preferably, two fourth positioning plates are symmetrically fixedly connected between the bottom inner wall of the cargo box and the bottom side of the storage partition. The fourth positioning plates are rotatably connected to the transverse bidirectional lead screw through bearings.

[0009] Preferably, a lifting screw is rotatably connected to the top side of the storage partition via a bearing. The top end of the lifting screw has an internal hexagonal groove, and a second limiting plate is fixedly connected to the bottom end of the threaded part of the lifting screw.

[0010] Preferably, a second guide rod is fixedly connected to the top side of the storage partition, which is symmetrically distributed with the lifting screw. A connecting sleeve plate is slidably connected through the body of the second guide rod.

[0016] Compared with the prior art, this utility model provides a multi-dimensional cargo anti-deviation fixing device, which has the following beneficial effects:

[0017] (1) This utility model achieves two-dimensional clamping and fixing of goods in a plane by setting transverse and longitudinal sliding grooves on the partition plate, in conjunction with the linkage drive of the transverse bidirectional lead screw and the longitudinal bidirectional lead screw. When the second motor starts, its output shaft drives the active gear to rotate through the rotating shaft. The active gear drives the two driven gears synchronously, so that the two transverse bidirectional lead screws with opposite screw directions rotate synchronously in opposite directions, thereby driving the two transverse clamping plates to move towards or away from each other along the transverse sliding groove, realizing the transverse clamping or release of goods; at the same time, the first motor drives the longitudinal bidirectional lead screw to rotate, and the second threaded sleeve plate on it slides along the third guide rod, driving the longitudinal clamping plate to move along the longitudinal sliding groove, realizing the longitudinal clamping of goods. The setting of transverse and longitudinal rubber pads not only increases the friction, but also avoids the wear of goods caused by direct contact. In addition, the third positioning plate supports the longitudinal bidirectional lead screw and the transverse bidirectional lead screw at the same time through the bearing, and the fourth positioning plate further supports the transverse bidirectional lead screw. This multi-positioning plate support structure effectively improves the stability of the lead screw transmission and reduces the space occupation. When the height of the lifting pressure plate needs to be adjusted, rotating the knob drives the drive shaft to rotate. The hexagonal prism at the bottom of the drive shaft inserts into the internal hexagonal groove at the top of the lifting screw, driving the lifting screw to rotate. This causes the first threaded sleeve to move along the screw axis, while the connecting sleeve slides along the second guide rod. Together, they drive the lifting pressure plate to rise and fall. The upper rubber pad finally contacts and presses against the top of the goods, forming a three-dimensional fixation. This design solves the problem of low internal space utilization in existing devices and can adapt to goods of different lengths, widths, and heights.

[0018] (2) This utility model incorporates a damper and a spring, forming a composite shock absorption structure. When the device is subjected to external vibration, the spring between the base plate and the mounting plate first absorbs some energy through elastic deformation, while the damper consumes the remaining kinetic energy through the viscous resistance of the internal damping medium, suppressing the reciprocating vibration of the spring and effectively protecting the goods from vibration. The handling frame on the base plate and the threaded groove on the mounting plate provide interfaces for hoisting and ground fixing, respectively. The cooperation between the first guide rod and the first limiting plate ensures the relative stability of the base plate and the mounting plate during handling, improving the practicality of the device.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] like Figures 3-6As shown, the multi-dimensional cargo anti-deviation fixing device provided by this utility model includes a cargo box 1. A storage partition 10 is horizontally fixedly connected to the inner wall of the cargo box 1. Two transverse sliding grooves 11 are symmetrically formed on the storage partition 10. Four longitudinal sliding grooves 12 are formed in a rectangular array on the storage partition 10. A longitudinal bidirectional lead screw 26 is rotatably mounted between the two inner walls of the cargo box 1 via bearings. Four third guide rods 27 are fixedly connected in a rectangular array to the inner walls of the two inner walls of the cargo box 1. The ends of the four third guide rods 27 away from the inner wall of the cargo box 1 are all fixedly connected to a second positioning plate 28 fixedly connected to the bottom inner wall of the cargo box 1. The longitudinal bidirectional lead screw 26 is driven by a first motor 29 fixedly installed on the outer wall of the cargo box 1. Two second threaded sleeves 30 are symmetrically mounted on the longitudinal bidirectional lead screw 26 and are slidably connected to the third guide rods 27. The top side of the second threaded sleeves 30... Two longitudinal clamping plates 31, which are adapted to the longitudinal slide groove 12, are symmetrically fixedly connected. The inner side of the longitudinal clamping plate 31 is bonded with a longitudinal rubber pad 32. Two transverse bidirectional lead screws 34 with opposite thread directions are rotatably installed between the inner walls of the two sides of the cargo box 1 through bearings. A driven gear 35 is fixedly installed at the same end of the two transverse bidirectional lead screws 34. A second motor 37 is fixedly installed on one side of the inner wall of the cargo box 1. The output end of the second motor 37 is connected to a rotating shaft 38 through a coupling. The end of the rotating shaft 38 away from the second motor 37 is fixedly installed with a driving gear 39 that meshes with the two driven gears 35. Two symmetrically arranged transverse clamping plates 40 are threadedly connected to the rods of the two transverse bidirectional lead screws 34. The transverse clamping plates 40 slide with the transverse slide groove 11. The inner side of the transverse clamping plates 40 is bonded with a transverse rubber pad 41. The cargo box 1 provides the overall load-bearing foundation for the device. The storage partition 10 carries the goods. The transverse slide 11 allows the transverse clamping plate 40 to slide, and the longitudinal slide 12 allows the longitudinal clamping plate 31 to slide, ensuring smooth movement of the clamping components. The first motor 29 drives the longitudinal bidirectional lead screw 26 to rotate. The second threaded sleeve 30 cooperates with the longitudinal bidirectional lead screw 26 to perform linear motion. The third guide rod 27 prevents the second threaded sleeve 30 from shifting with the lead screw rotation. The second positioning plate 28 fixes the third guide rod 27 to stabilize the structure. Then, the second threaded sleeve 30 drives the longitudinal clamping plate 31 to achieve longitudinal clamping of the goods. The longitudinal rubber pad 32 increases the friction with the goods and avoids wear. The second motor 37 drives the drive gear 39 to rotate through the rotating shaft 38. The drive gear 39 drives the driven gear 35 to make the two transverse bidirectional lead screws 34 with opposite thread directions rotate synchronously in opposite directions. The transverse clamping plate 40 cooperates with the transverse bidirectional lead screw 34 to achieve transverse clamping of the goods. The transverse rubber pad 41 also increases friction and prevents wear.

[0030] Example 2

[0031] Please see Figures 4-6A third positioning plate 33 is fixedly connected between the middle of the bottom inner wall of the cargo box 1 and the middle of the bottom side of the storage partition 10. The third positioning plate 33 is rotatably connected to the longitudinal bidirectional lead screw 26 and the transverse bidirectional lead screw 34 through bearings. The third positioning plate 33 provides rotational support for the longitudinal bidirectional lead screw 26 and the transverse bidirectional lead screw 34, counteracts the radial force when the lead screw rotates, avoids lead screw deviation or wobbling, ensures the transmission accuracy of the longitudinal and transverse clamping mechanisms, and ensures accurate and reliable clamping action.

[0032] Example 3

[0033] Please see Figure 4 and Figure 5 Two fourth positioning plates 36 are symmetrically fixedly connected between the bottom inner wall of the cargo box 1 and the bottom side of the storage partition 10. The fourth positioning plates 36 are rotatably connected to the transverse bidirectional lead screw 34 through bearings. The fourth positioning plates 36 cooperate with the third positioning plate 33 to support the transverse bidirectional lead screw 34, enhance the rotational stability of the transverse bidirectional lead screw 34, prevent deformation or vibration due to its large span, ensure the smooth movement of the transverse clamping plate 40, and improve the transverse clamping effect.

[0034] Example 4

[0035] Please see Figure 3 , Figure 4 and Figure 6 The top side of the storage partition 10 is rotatably connected to a lifting screw 17 via a bearing. The top of the lifting screw 17 has an internal hexagonal groove, and a second limiting plate 18 is fixedly connected to the bottom of the threaded portion of the lifting screw 17. A first threaded sleeve 21 is also installed on the threaded portion of the lifting screw 17. The internal hexagonal groove at the top of the lifting screw 17 receives external driving force to stabilize its rotation. The first threaded sleeve 21 cooperates with the lifting screw 17 to convert the screw's rotational motion into its own linear motion. The second limiting plate 18 limits the downward movement of the first threaded sleeve 21 to prevent it from detaching from the screw or being damaged by collision.

[0036] Example 5

[0037] Please see Figure 4 and Figure 6 The top side of the storage partition 10 is fixedly connected to a second guide rod 19 symmetrically distributed with the lifting screw 17. A connecting sleeve plate 42 is slidably connected through the body of the second guide rod 19. The top ends of both the lifting screw 17 and the second guide rod 19 are provided with a first positioning plate 20 fixedly connected to the inner wall of the cargo box 1. The second guide rod 19 provides sliding guidance for the connecting sleeve plate 42, preventing the connecting sleeve plate 42 from shifting. The first positioning plate 20 supports the rotation of the lifting screw 17 and fixes the second guide rod 19, ensuring the structural stability of the lifting-related components and laying the foundation for subsequent smooth lifting.

[0038] Example 6

[0039] Please see Figure 4 and Figure 6 The top end of the lifting screw 17 is rotatably connected to the first positioning plate 20, and the top end of the second guide rod 19 is fixedly connected to the first positioning plate 20. A lifting pressure plate 22 is fixedly connected between the first threaded sleeve 21 and the connecting sleeve 42, and an upper rubber pad 23 is adhered to the bottom side of the lifting pressure plate 22. The lifting pressure plate 22 rises and falls smoothly under the action of the first threaded sleeve 21 and the connecting sleeve 42, thereby pressing or releasing the top of the goods. The upper rubber pad 23 increases the friction with the goods to improve the fixing effect and at the same time prevents the goods from being worn.

[0040] Example 7

[0041] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 The bottom of the cargo box 1 is fixedly connected to a bottom plate 2, and two transport frames 9 are symmetrically fixedly connected to the top of the bottom plate 2. Four dampers 3 are fixedly installed in a rectangular array on the bottom of the cargo box 1, and the bottom ends of the dampers 3 are all fixedly connected to a mounting plate 4. The bottom plate 2 provides bottom support for the cargo box 1, the transport frames 9 facilitate the hooking of external hoisting equipment, enabling convenient handling of the device, the dampers 3 consume vibration energy and suppress the transmission of vibration to the cargo, and the mounting plate 4 provides the mounting foundation for the dampers 3 and also serves as the connection carrier between the device and the external bearing surface.

[0042] Example 8

[0043] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 The mounting plate 4 has multiple threaded grooves symmetrically formed on it. Multiple first guide rods 7 are symmetrically fixedly connected to the top side of the mounting plate 4, and the first guide rods 7 are slidably connected to the base plate 2. A first limiting plate 8 is fixedly connected to the top of each first guide rod 7. Springs 5, which are fixedly connected to the base plate 2 and the mounting plate 4, are sleeved on the outer sides of the damper 3 and the first guide rods 7. The threaded grooves 6 are used to fix the device to the transport equipment or the ground via bolts, improving the stability of the device during placement and transport. The first guide rods 7 provide guidance for the movement of the base plate 2 relative to the mounting plate 4, preventing deviation. The first limiting plate 8 limits the upward movement of the base plate 2, preventing it from detaching from the guide rods. The springs 5 ​​absorb vibration energy, forming a composite damping system with the damper 3, further reducing the impact of vibration on the goods.

[0044] Example 9

[0045] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6Each of the four corners of the top side of the cargo box 1 is fixedly connected with a threaded seat 13. The four threaded seats 13 are threadedly connected to a cover plate 14 by bolts 16. A handle 15 is fixedly connected to the center of the top side of the cover plate 14. The threaded seats 13 and bolts 16 cooperate to fix and remove the cover plate 14, thereby controlling whether the top of the cargo box 1 is closed or open to prevent dust and debris interference. The handle 15 is convenient for operators to hold and facilitates the installation and removal of the cover plate 14.

[0046] Example 10

[0047] Please see Figure 6 A drive shaft 24 is slidably connected through the cover plate 14. The bottom end of the drive shaft 24 is hexagonal prism-shaped and is movably connected to the inner hexagonal groove at the top of the lifting screw 17. A knob 25 is fixedly connected to the top of the drive shaft 24. The knob 25 facilitates the operator to apply force and transmit torque. The drive shaft 24, through the engagement of its bottom hexagonal prism with the inner hexagonal groove of the lifting screw 17, drives the lifting screw 17 to rotate, providing power for the lifting and lowering of the lifting pressure plate 22, thereby adjusting the fixed state of the top of the goods.

[0048] The working principle of the multi-dimensional cargo anti-displacement fixing device provided by this utility model is as follows:

[0049] First, when placing goods inside the device, unscrew the bolt 16 on the threaded seat 13 and remove the cover plate 14 using the handle 15. At this time, the top of the cargo box 1 is open. Since the lifting pressure plate 22, the first threaded sleeve plate 21, and the connecting sleeve plate 42 occupy a small area and there is enough space between them and the storage partition 10, the goods can be directly bypassed by these components and placed stably in the middle of the top side of the storage partition 10 without significant obstruction.

[0050] After the goods are placed, the second motor 37 is started. Its output end drives the drive gear 39 to rotate through the rotating shaft 38. The drive gear 39 simultaneously meshes with and drives two driven gears 35, causing the two transverse bidirectional lead screws 34 to rotate synchronously in opposite directions under the support of the third positioning plate 33 and the fourth positioning plate 36. Since the threads of the transverse bidirectional lead screws 34 are opposite, the two transverse clamping plates 40 connected to them will move towards each other along the transverse slide groove 11 until the transverse rubber pads 41 are tightly attached to the outer walls of both sides of the goods, thus completing the transverse fixation of the goods. At the same time, the first motor 29 is started, which drives the longitudinal bidirectional lead screw 26 to rotate under the bearing support of the third positioning plate 33 and the inner wall of the cargo box 1. The two second threaded sleeves 30 on the longitudinal bidirectional lead screw 26 slide along the third guide rod 27, causing the longitudinal clamping plates 31 to move towards each other along the longitudinal slide groove 12, so that the longitudinal rubber pads 32 are tightly attached to the front and rear outer walls of the goods, thus achieving the longitudinal fixation of the goods. At this time, the planar position of the goods on the storage partition 10 is completely locked.

[0051] If the cargo is too high and requires top restraint, the knob 25 on the cover plate 14 can be rotated to drive the drive shaft 24 to rotate. The hexagonal prism structure at the bottom of the drive shaft 24 is inserted into the internal hexagonal groove at the top of the lifting screw 17, thereby driving the lifting screw 17 to rotate under the bearing support of the first positioning plate 20 and the storage partition 10. When the lifting screw 17 rotates, the first threaded sleeve 21 moves downward along its threaded portion, while the connecting sleeve 42 slides down synchronously along the second guide rod 19. Together, they drive the lifting pressure plate 22 to descend smoothly until the upper rubber pad 23 is tightly pressed against the top of the cargo. The second limiting plate 18 can prevent the first threaded sleeve 21 from moving down too much and causing damage to the components. At this time, the cargo is completely fixed in three-dimensional space.

[0052] During the handling or transportation of the device, if it is subjected to external collisions or vibrations, the cargo box 1 transmits the vibration force to the damper 3 and spring 5 through the base plate 2. The spring 5 first absorbs part of the energy through elastic deformation, while the damper 3 consumes the remaining vibration energy through the viscous effect of its internal damping medium, preventing the vibration force from being directly transmitted to the cargo and causing the clamps to loosen. At the same time, the first guide rod 7 slides along the base plate 2, cooperating with the first limit plate 8 to limit the relative displacement between the base plate 2 and the mounting plate 4, ensuring the stability of the overall structure. During handling, the device can be hoisted using the handling frame 9 on the base plate 2, or fixed to the transport equipment using the threaded groove 6 on the mounting plate 4.

[0053] When it is necessary to remove the goods, first turn the knob 25 in the opposite direction to raise and reset the lifting plate 22, then start the first motor 29 and the second motor 37 in the opposite direction to move the longitudinal clamping plate 31 and the transverse clamping plate 40 in opposite directions to release the goods. Finally, remove the cover plate 14 to remove the goods from the storage partition 10 and complete the entire operation process.

[0054] The metal structures involved in this utility model, such as motors and lead screws, must be made of high-quality rust-proof materials or treated with mature waterproofing processes. This is to effectively prevent device malfunctions caused by rust or water ingress in structural components. Since the aforementioned rust-proof materials and waterproofing processes are all within the scope of existing technology, they will not be described in detail in this utility model.

[0055] It is necessary to explain that the lead screw thread in the embodiment adopts a trapezoidal thread structure. According to the mechanical design principle, when the thread helix angle is less than the friction angle, the thread pair has a natural self-locking function, which can prevent it from rotating on its own without the action of external force. The lead screw can be self-locked without turning the knob.

[0056] The motor involved in the embodiments, its matching control system, electromagnetic switch and pipeline circuit can also be provided by the manufacturer. Apart from that, the power supply module, circuit and electronic components and control module involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0057] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
