A transport container

Abstract

This utility model applies to the field of container technology, providing a transport container that solves the problems of ineffective securing of small items and interference from mixed loading in traditional containers through a core design of "zonal limiting + layered constraint," thereby improving the stability of cargo transportation. Limiting components distributed from top to bottom on both sides of the partition can precisely constrain layers of cargo of different heights, adapting to the securing needs of cargo of varying sizes. Unlike traditional top-pressing fixing, this device uses lateral restraint straps to encircle the cargo, with hooks and rings quickly engaging to achieve initial securing. Combined with the synchronous winding function of the winding unit, it ensures balanced force on both sides of the restraint straps, precisely controlling the tension—avoiding both excessive looseness leading to cargo displacement and excessive tightness causing damage. The self-locking characteristic of the worm gear drive locks the position of the winding and unwinding rollers, preventing the restraint straps from loosening. Control buttons can also activate corresponding layer components one-to-one, achieving precise layered limiting and completely solving the problem of ineffective securing of small items.

Description

Technical Field

[0001] This utility model relates to the field of container technology, specifically a transport container. Background Technology

[0002] In modern logistics and supply chain systems, transport containers, as standardized cargo carriers, directly determine cargo damage rates and transportation safety through their cargo securing performance. This is especially true in scenarios such as e-commerce with mixed product categories, the transport of precision instruments, and the distribution of daily necessities, where the need for adaptable securing of goods of different sizes and shapes is becoming increasingly urgent. Effective securing measures must offset the bumps, vibrations, and inertial impacts during transportation, preventing cargo shifting and collisions. This is a core guarantee for reducing logistics costs and improving delivery quality.

[0003] To address the issue of cargo collisions, the industry has developed various damage prevention technologies, such as the anti-collision logistics transport box disclosed in patent CN223328237U. This design uses a hydraulic rod to drive a pressure plate that adheres to the top surface of the cargo from top to bottom, limiting its movement. Combined with a crash net, it absorbs external impacts, representing a significant improvement over traditional simple fixing methods. However, this solution still has limitations in adaptability: its core relies on the single fixing logic of "top-down pressure." When large and small cargoes are mixed inside the container, the pressure plate cannot effectively contact and maintain stable pressure on small cargoes that are not tall enough, leaving them unrestrained. Consequently, cargo collisions can still occur during container transport.

[0004] Therefore, developing a transport container that can accommodate goods of different volumes and achieve stable constraints has become an urgent need to solve the problem of securing small-volume goods and improve the safety of logistics transportation. Utility Model Content

[0005] The purpose of this invention is to provide a transport container to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A transport container includes a container body, a partition fixedly installed inside the container body, and symmetrically arranged limiting mechanisms on both sides of the partition inside the container body. The limiting mechanisms include limiting components arranged at equal intervals from top to bottom. Each limiting component includes a hook, a restraining strap, a hanging ring, and a winding unit. The restraining straps are symmetrically arranged on both sides of the partition. A hook is fixedly installed at one end of the restraining strap near the opening of the container body, and the other end is connected to the winding unit installed inside the container body. A hanging ring adapted to the hook is fixedly installed on the side wall of the partition. The winding unit is used to provide power for the synchronous winding and unwinding of the restraining straps on both sides.

[0008] As a further embodiment of this utility model: the winding unit includes a winding box fixedly installed inside the container body, a pair of winding and unwinding rollers rotatably installed in parallel inside the winding box, and a power module for driving the two winding and unwinding rollers to rotate synchronously. The winding box has a through hole on its side for a binding strap to pass through. The binding strap is wound around the winding and unwinding rollers. A first gear is coaxially fixedly installed on each of the two winding and unwinding rollers, and a second gear is meshed between the two first gears. The power module is used to provide power for the rotation of one of the winding and unwinding rollers.

[0009] As a further embodiment of this utility model: the power module includes a top cover, a worm gear and a worm. The top cover is fixedly installed on the take-up box, and the worm is rotatably installed inside the top cover. A worm gear that meshes with the worm is also provided inside the top cover. The worm is driven by a motor provided on the take-up box, and the worm gear is coaxially fixedly installed on one of the unwinding rollers.

[0010] As a further embodiment of this utility model, control buttons are also installed on the partition corresponding to the positions of multiple restraint straps.

[0011] As a further embodiment of this utility model: the side wall of the container body is also symmetrically provided with inwardly recessed grooves, and a frame plate is installed in the groove through multiple buffer modules, and an anti-collision net is provided in the frame plate.

[0012] As a further embodiment of this utility model: the buffer module includes a sleeve rod fixedly installed in the groove, a telescopic rod movably inserted in the sleeve rod, and a buffer spring sleeved on the telescopic rod. The end of the telescopic rod is provided with a threaded hole, and the frame plate is detachably installed on the telescopic rod by screws.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through its core design of "zonal limiting + layered constraint," effectively addresses the pain points of traditional containerized small cargo fixation failure and mixed-cargo interference, significantly improving cargo transportation stability. Limiting components distributed from top to bottom on both sides of the partition can precisely constrain cargo of different heights, adapting to the fixation needs of cargo of varying sizes. Unlike traditional top-pressing fixation, this device uses lateral restraint straps to encircle the cargo, with hooks and rings quickly engaging to achieve initial fixation. Combined with the synchronous winding function of the winding unit, it ensures balanced force on both sides of the restraint straps, precisely controlling tension—avoiding both excessive looseness leading to cargo displacement and excessive tightness causing damage. The self-locking characteristic of the worm gear drive locks the position of the winding and unwinding rollers, preventing the restraint straps from loosening. Control buttons can also activate corresponding layer components one-to-one, achieving precise layered limiting and completely solving the problem of small cargo fixation failure.

[0015] 2. In the groove of the container side wall of this utility model, the anti-collision net and the buffer module form a double protection: when an impact occurs, the anti-collision net first deforms to absorb part of the impact force, and the buffer spring further dissipates the energy through the extension and retraction of the telescopic rod, converting the instantaneous impact into elastic potential energy and releasing it slowly, which greatly reduces the damage to the cargo caused by the side impact.

Detailed Implementation

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] Example 1

[0025] Please see Figure 1-6 A transport container includes a container body 1, with a partition 2 fixedly installed inside the container body 1. The container body 1 provides a sealed carrying space for cargo transportation and is adapted to the needs of standardized logistics transfer. The partition 2 divides the interior of the container into two symmetrical storage areas, enabling the classified storage of goods and providing an installation base for the limiting mechanism to avoid mutual interference between mixed goods.

[0026] Inside the container body 1, symmetrically arranged on both sides of the partition 2, are limiting mechanisms. These mechanisms include limiting components spaced evenly from top to bottom. Each limiting component includes a hook 3, a restraining strap 4, a hanging ring 5, and a winding unit. The restraining straps 4 are symmetrically arranged on both sides of the partition 2. A hook 3 is fixedly installed at one end of the restraining strap 4 near the opening of the container body 1, and the other end is connected to the winding unit inside the container body 1. A hanging ring 5 adapted to the hook 3 is fixedly installed on the side wall of the partition 2. The limiting components distributed from top to bottom can constrain goods of different heights in layers, ensuring that a suitable fixing layer can be found regardless of the size of the goods. The restraining straps 4 wrap around the side wall of the goods to form a lateral embrace, and the hook 3 and hanging ring 5 quickly connect to achieve initial fixation, replacing the traditional top-down pressing method. This ensures that even small-volume goods can be effectively constrained, solving the problem of fixation failure of small goods in the prior art.

[0027] The winding unit provides power for the synchronous winding and unwinding of the two side restraint straps 4. The winding unit can precisely control the tension of the restraint straps 4 to avoid the goods shifting due to being too loose or being crushed and damaged due to being too tight. At the same time, it can realize the synchronous force on both side restraint straps to ensure the goods are fixed and balanced.

[0028] Example 2

[0029] Please see Figure 2 and 4 The winding unit includes a winding box 6 fixedly installed inside the container body 1, a pair of winding and unwinding rollers 7 rotatably installed in parallel inside the winding box 6, and a power module that drives the two winding and unwinding rollers 7 to rotate synchronously. The winding box 6 has through holes on its side for the binding strap 4 to pass through. The binding strap 4 is wound around the winding and unwinding roller 7. A first gear 8 is coaxially fixedly installed on each of the two winding and unwinding rollers 7, and a second gear 9 is meshed between the two first gears 8. The power module is used to provide power for the rotation of one of the winding and unwinding rollers 7. The winding box 6 provides protection for the winding and unwinding mechanism to prevent damage to the components from cargo collisions. The winding and unwinding roller 7 realizes the winding and unwinding of the binding strap 4. The meshing of the first gear 8 and the second gear 9 ensures that the winding and unwinding rollers on both sides rotate synchronously.

[0030] Example 3

[0031] Please see Figure 4The power module includes a top cover 10, a worm gear 12, and a worm 11. The top cover 10 is fixedly mounted on the take-up box 6, and the worm 11 is rotatably mounted inside the top cover 10. The worm gear 12, which meshes with the worm 11, is also provided inside the top cover 10. The worm 11 is driven by a motor 13 mounted on the take-up box 6. The worm gear 12 is coaxially fixedly mounted on one of the unwinding rollers 7. The top cover 10 protects the worm gear 12 and the worm 11 from dust and collisions with goods. The meshing transmission between the worm gear 12 and the worm 11 has a self-locking function, which can lock the position of the unwinding roller 7 after winding is completed, preventing the binding strap 4 from loosening without the need for an additional braking structure. The motor 13 provides stable power, enabling controllable adjustment of the tightening force of the binding strap 4.

[0032] Example 4

[0033] Please see Figure 1 and Figure 2 Control buttons 14 are also installed on the partition 2 corresponding to multiple restraint straps 4. The control buttons 14 control the limit components of different heights one by one, and can selectively start the corresponding winding unit according to the layering of goods to achieve precise limiting.

[0034] Example 5

[0035] Please see Figure 1 and Figure 5 The side walls of the container body 1 are also symmetrically provided with inwardly recessed grooves 15. Frame plates 16 are installed in the grooves 15 through multiple buffer modules 18. Anti-collision nets 17 are installed in the frame plates 16. The grooves 15 provide installation space for the buffer structure, preventing it from occupying storage area; the frame plates 16 provide a supporting frame for the anti-collision nets 17, ensuring that the anti-collision nets 17 remain open; the anti-collision nets 17 can deform to absorb external impact forces, and together with the buffer modules 18, achieve secondary buffering, reducing the impact of side impacts on the internal cargo.

[0036] Example 6

[0037] Please see Figure 5 and Figure 6 The buffer module 18 includes a sleeve rod 20 fixedly installed in the groove 15, a telescopic rod 21 movably inserted in the sleeve rod 20, and a buffer spring 19 sleeved on the telescopic rod 21. The end of the telescopic rod 21 is provided with a threaded hole 22. The frame plate 16 is detachably installed on the telescopic rod 21 by screws. The sleeve rod 20 and the telescopic rod 21 form a telescopic structure to provide displacement space for buffering. The buffer spring 19 absorbs impact energy through elastic deformation and slowly releases the instantaneous impact force into elastic potential energy. The threaded hole 22 enables the detachable connection between the frame plate 16 and the telescopic rod 21, which facilitates the replacement and maintenance of the anti-collision net 17 after damage.

[0038] Working principle:

[0039] During loading, goods of different volumes are sorted and stacked on both sides of the partition 2. Based on the stacking height, the corresponding layer control button 14 is pressed to activate the power module. Motor 13 drives worm gear 11 to rotate. Worm gear 11 meshes with worm wheel 12, causing one of the winding rollers 7 to rotate. This winding roller 7, through the meshing of first gear 8 and second gear 9, drives the other winding roller 7 to rotate synchronously, releasing the wound restraint strap 4. The restraint strap 4 is then wrapped around the side wall of the corresponding layer of goods. The hook 3 is hung on the hanging ring 5 of the partition 2. Pressing control button 14 again reverses motor 13, causing the winding roller 7 to wind up the restraint strap 4 until it is firmly against the side wall of the goods, forming a stable constraint. The self-locking function of worm wheel 12 and worm gear 11 locks the winding roller 7, preventing the restraint strap 4 from loosening. Multiple layers of restraint straps 4 provide lateral restraint for goods of different heights (including small-volume goods), preventing them from swaying during transport. When the container body 1 is subjected to a side impact, the anti-collision net 17 first deforms to absorb part of the impact force. The remaining impact force pushes the frame plate 16 to squeeze the telescopic rod 21. The telescopic rod 21 retracts into the sleeve rod 20 and compresses the buffer spring 19. The buffer spring 19 further absorbs energy, achieving double buffer protection. During unloading, pressing the control button 14 controls the unwinding roller 7 to release the restraint belt 4, and the hook 3 can be removed to take out the goods. The entire operation is convenient and can also ensure the stable fixation of goods of different volumes.

Apart from that, the controllers 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 improvements to the internal structure and methods.

[0041] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. 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.
