Description

Technical Field

[0001] This invention belongs to the technical field of air cargo transportation, specifically relating to a steering device for vertical limiting of container movement and a container. Background Technology

[0002] Currently, air freight is an important component of the modern logistics system, characterized by its high efficiency and speed. Civil aircraft cargo holds require specialized movement limiting devices to restrict and secure containers. Among these, the vertical movement limiting device for containers, used to limit vertical displacement, is a core component ensuring the safety and stability of container loading and unloading operations and air transport.

[0003] However, in the existing air cargo sector, the container movement limiting devices used in aircraft cargo holds often adopt a manually extended front and rear movement limiting structure. After the container pallet is loaded into place, the operator must manually extend the limiting component to achieve the limiting and fixing of the container. This can only achieve the limiting function in one direction, without rotation avoidance and automatic reset structure, and the limiting action needs to be completed manually.

[0004] Meanwhile, most current limiting devices adopt an independent structure, making it difficult to integrate with the LRU components in the aircraft cargo hold. This results in high structural redundancy and a large space occupation, failing to meet the lightweight and compact design standards of civil aircraft cargo holds. Furthermore, the devices lack automatic centering and resetting capabilities, making them prone to interference with the limiting components during container loading and unloading, thus failing to simultaneously meet the dual requirements of vertical limiting and smooth loading and unloading. In summary, current container limiting devices involve significant manual intervention, making it difficult to achieve automatic rotation and centering resetting during container loading and unloading, resulting in insufficient smoothness in both vertical limiting and loading / unloading. Summary of the Invention

[0005] This invention provides a steering device and a container for vertical movement restriction of a container, aiming to solve the problems of existing container movement restriction devices, which involve a lot of manual labor, making it difficult to achieve automatic rotation, avoidance, and centering reset during the loading and unloading process, and resulting in insufficient smoothness of vertical movement restriction and loading and unloading.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: This invention provides a steering device for vertically limiting the movement of a container, comprising a stop block, a steel bushing, a lever, a stop ring, a torsion spring, a support, and an anti-loosening component, wherein: The stop includes a latch and a shaft. The lower surface of the latch has a vertical limiting surface. The outer circumferential surface of the shaft is provided with a first plane and a second plane. The support is provided with a first groove and a second groove. A steel bushing is provided between the shaft and the first groove. A stop ring is provided in the second groove. The stop ring includes a cylinder and an ear ring. The cylinder is located between the torsion spring and the shaft. A torsion spring is fitted onto the outer circumferential surface of the shaft. One end of the torsion spring forms a stop-limiting fit with the support, and the other end forms a stop-fit ​​with the lever. The lever is fitted onto the outer circumferential surface of the shaft and has a third plane and a fourth plane. The third plane contacts the end of the torsion spring, and the fourth plane contacts the second plane. The anti-loosening component is connected to the extended end of the shaft that passes through the first groove, and is used to limit the shaft axially and prevent it from loosening. The shaft can drive the paddle to rotate under the action of external force, so that the torsion spring generates torsional torque. The torsional torque of the torsion spring can be transmitted to the shaft through the paddle, so as to drive the shaft and the locking tongue to reset.

[0007] In some embodiments, the support is also provided with a side lug and a base, the first groove is a through hole adapted to the shaft, and the second groove is used to accommodate the stop ring; The base is used to connect external LRU components, and the side lugs are used to connect external LRU components in the same heading.

[0008] Furthermore, the earring is a structure located on both sides of the stop ring, and the earring has a screw through hole. The screw passes through the screw through hole of the earring to connect the stop ring and the support.

[0009] In some embodiments, the outer circumferential surface of the shaft is further provided with a first arc surface and a second arc surface, wherein the first arc surface and the first plane are arranged adjacent to each other, and the second arc surface and the second plane are arranged adjacent to each other. Furthermore, when the shaft rotates, the first plane separates from the torsion spring, the second plane separates from the fourth plane, the first arc surface contacts the torsion spring, and the second arc surface contacts the fourth plane.

[0010] In some embodiments, the center of the paddle has a mounting hole that matches the outer circumferential surface of the shaft, and the third plane and the fourth plane are two mutually perpendicular planes.

[0011] In some embodiments, the outer ring of the steel bushing forms an interference fit with the inner wall of the first groove, and the inner ring of the steel bushing forms a clearance fit with the outer circumferential surface of the shaft.

[0012] In some embodiments, the anti-loosening component includes a washer, a nut, and a cotter pin. The washer and nut are sequentially fitted onto the extended end of the shaft, and the nut forms a threaded connection with the extended end of the shaft. The cotter pin passes through the radial pin hole of the shaft and the radial through hole of the nut.

[0013] Furthermore, one end face of the washer is fitted with the outer end face of the support, and the other end face is fitted with the clamping end face of the nut.

[0014] The present invention also provides a container, the container including the above-described steering device for limiting the vertical movement of the container.

[0015] The present invention provides a steering device for vertically limiting the movement of a container, which has at least the following beneficial effects.

[0016] This invention enables the shaft to rotate under external force, causing the torsion spring to accumulate torsional torque. The torsion spring torque is transmitted back to the shaft through the torsion spring and drives the shaft and locking tongue to automatically reset. This effectively reduces the manual operation intensity during container loading and unloading. The vertical limiting surface can complete the vertical limiting of the container after reset. The cylinder can limit the initial installation position of the torsion spring, ensuring the stability of the torsion spring torque transmission. The steel bushing provides stable structural support for the shaft rotation. Furthermore, the anti-loosening component provides reliable axial limiting and anti-loosening protection for the shaft, ensuring the stability of the overall structure of the device. It can be relatively adapted to the installation space requirements of aircraft cargo holds, and to a certain extent realizes the functions of container loading and unloading avoidance, automatic reset and vertical limiting, ensuring smooth loading and unloading of pallets, meeting the requirements of vertical limiting and lightweight, effectively reducing the workload of personnel and improving work efficiency.

[0027] How can we achieve automatic rotation and centering reset during the loading and unloading process of the container, while taking into account both vertical movement requirements and smooth loading and unloading, and integrate it with the LRU component in the aircraft cargo hold, meeting the design requirements of lightweight and integration?

[0028] like Figures 1-7 As shown, the present invention provides a steering device for vertically limiting the movement of a container, comprising a stop block 1, a steel bushing 2, a lever 3, a stop ring 4, a torsion spring 5, a support 6, and an anti-loosening component, wherein: The stop block 1 includes a locking tongue 11 and a shaft 13. The lower surface of the locking tongue 11 has a vertical limiting surface 12. The outer peripheral surface of the shaft 13 is provided with a first plane 131 and a second plane 132. The support 6 is provided with a first groove 61 and a second groove 64. The steel bushing 2 is provided between the shaft 13 and the first groove 61. The stop ring 4 is provided in the second groove 64. The stop ring 4 includes a cylinder 41 and an ear ring 42. The cylinder 41 is located between the torsion spring 5 and the shaft 13. The torsion spring 5 is fitted onto the outer circumferential surface of the shaft 13. One end of the torsion spring 5 forms an abutment limit fit with the support 6, and the other end forms an abutment fit with the lever 3. The lever 3 is fitted onto the outer circumferential surface of the shaft 13. The lever 3 is provided with a third plane 31 and a fourth plane 32. The third plane 31 contacts the end of the torsion spring 5, and the fourth plane 32 contacts the second plane 132. The anti-loosening component is connected to the extended end of the shaft 13 that passes through the first groove 61, and is used to axially limit and prevent the shaft 13 from loosening; the shaft 13 can drive the paddle 3 to rotate under the action of external force, so that the torsion spring 5 generates torsional torque, and the torsional torque of the torsion spring 5 can be transmitted to the shaft 13 through the paddle 3, so as to drive the shaft 13 and the locking tongue 11 to reset.

[0029] This invention provides a steering device for vertical movement restriction of containers, which can ensure smooth loading and unloading of pallets during operation. It can not only meet the vertical movement restriction requirements, but also save weight, reduce the workload of operators, and improve work efficiency, thus having practical significance.

[0030] Furthermore, the support 6 of the present invention is provided with side lugs 62 and a base 63. The first groove 61 is a through hole adapted to the shaft 13, and the second groove 64 is used to accommodate the stop ring 4. The base 63 is used to connect the external LRU assembly (i.e., the side guide rail 10), and the side lugs 62 are used to connect the external LRU assembly in the same direction, realizing the installation of the steering device with the existing LRU assembly in the aircraft cargo hold, eliminating the need for a separate mounting base, simplifying the installation layout inside the cargo hold. The second groove 64 of the support 6 can stably accommodate the stop ring 4. The lugs 42 on both sides of the stop ring 4 are fixedly connected to the support 6 by screws, which can prevent the stop ring 4 from shifting during the operation of the device, ensuring the stability of the initial position of the torsion spring 5, and providing support for torque transmission and automatic reset functions.

[0031] Furthermore, the outer circumferential surface of the shaft 13 of the present invention is also provided with a first arc surface 133 and a second arc surface 134. The first arc surface 133 and the first plane 131 are arranged adjacent to each other, and the second arc surface 134 and the second plane 132 are arranged adjacent to each other. The first arc surface 133 and the second arc surface 134 enable the shaft 13 to achieve a smooth transition from planar fit to arc surface fit during rotation. When the shaft 13 rotates, the first plane 131 separates from the torsion spring 5, the second plane 132 separates from the fourth plane 32, the first arc surface 133 contacts the torsion spring 5, and the second arc surface 134 contacts the fourth plane 32. This can effectively prevent the shaft 13 from jamming during rotation, ensure the smoothness of the shaft 13's rotation, and at the same time allow the torsion spring 5 to smoothly generate and accumulate torsional torque, ensuring the smooth execution of subsequent reset actions and improving the stability and reliability of the device operation.

[0032] The paddle 3 of this invention has a mounting hole at its center that matches the outer circumferential surface of the shaft 13. The third plane 31 and the fourth plane 32 are two mutually perpendicular planes, which can ensure the coaxial fitting accuracy of the paddle 3 and the shaft 13. The mutually perpendicular third plane 31 and the fourth plane 32 can stably fit the end of the torsion spring 5 and the second plane 132 of the shaft 13, respectively, ensuring the accuracy and effectiveness of torque transmission. The interference fit between the outer ring of the steel bushing 2 and the inner wall of the first groove 61 can ensure its own installation firmness, while the clearance fit between the inner ring and the outer circumferential surface of the shaft 13 provides low-friction rotational support for the shaft 13, reducing the rotational wear of the shaft 13 and improving the smoothness of the shaft 13's rotation.

[0033] Furthermore, in a steering device for vertical movement limitation of a container according to the present invention, the anti-loosening component includes a washer 7, a nut 8, and a cotter pin 9. The washer 7 and the nut 8 are sequentially fitted onto the extended end of the shaft 13, and the nut 8 forms a threaded connection with the extended end of the shaft 13. The cotter pin 9 passes through the radial pin hole of the shaft 13 and the radial through hole of the nut 8. The present invention, through a multi-stage anti-loosening limiting structure, can prevent the nut 8 from loosening under vibration. The two end faces of the washer 7 respectively conform to the outer end face of the support 6 and the pressing end face of the nut 8, which can disperse the pressing force of the nut 8, avoid pressure damage on the contact surface between the support 6 and the shaft 13, and further improve the reliability of the axial limiting and anti-loosening of the shaft 13.

[0034] The present invention also provides a container, the container including the above-described steering device for limiting the vertical movement of the container.

[0035] The following describes in detail the specific functions and principles of a steering device for vertical movement limitation of a container according to the present invention.

[0036] In a steering device for vertical movement limitation of a container, the present invention provides a support 6 for positioning and installation, a steel bushing 2 for press-fitting into a first groove 61, a shaft 13 for passing through the inner hole of the steel bushing 2, and a stop ring 4 for being placed in a second groove 64. A screw passes through an ear ring 42 to fix the stop ring 4, and a cylinder 41 is inserted between a torsion spring 5 and a shaft 13. The torsion spring 5 is fitted onto the shaft 13, with one end of the torsion spring 5 abutting against the support 6 for limiting its position, and a first plane 131 abutting against the torsion spring 5. A paddle 3 is fitted onto the shaft 13, with a third plane 31 close to the end of the torsion spring 5 and a fourth plane 32 close to the second plane 132. Washers 7 and nuts 8 are sequentially installed on the shaft end. A cotter pin 9 passes through the shaft 13 and the nut 8 to prevent loosening. The support 6 is fixed to the side guide rail 10 by a base 63, and the side ear 62 passes through and connects to the guide rail 11.

[0037] In this invention, the locking tongue 11 is centered, with the first plane 131 abutting against the torsion spring 5 and the second plane 132 abutting against the fourth plane 32. In some operating conditions, the container pallet touches the locking tongue 11; the locking tongue 11 drives the shaft 13 to rotate along the heading / counter-heading direction; the first plane 131 separates from the torsion spring 5, and the second plane 132 separates from the fourth plane 32; the first arc surface 133 abuts against the torsion spring 5, and the second arc surface 134 abuts against the fourth plane 32; the shaft 13, the lever 3, and the torsion spring 5 generate a torsional torque; the pallet completely passes over the locking tongue 11; the torque of the torsion spring 5, the lever 3, the shaft 13, and the locking tongue 11 return to their centered position, achieving automatic reset; the vertical limiting surface 12 of the locking tongue 11 limits the pallet, achieving vertical limiting, thus completing the limiting action.

[0038] The present invention will be further described in detail below through specific embodiments.

[0039] In this invention, a steering device for vertical movement limitation of a container is provided on a support 6, which has a through hole, i.e., a first groove 61, adapted to the shaft 13; the steering device is fixed to the LRU assembly via the support 6. For example, it can be integrated into the side guide rails 10 installed on both sides of the cargo hold floor near the inner wall of the hold, with the base 63 installed on the side guide rails 10. The connecting guide rail 11 is used to splice the segmented side guide rails 10, realizing the continuous arrangement of the side guide rails 10 along the flight direction. Along the slide rail direction, the side guide rails 10 in the same flight direction are connected to the connecting guide rail 11 via the side lugs 62. Figure 8 As shown (this is only one embodiment; the structure of the support 6 can be changed according to different connection forms between the LRU and the support 6, and it can also be implemented).

[0040] The second groove 64 is used to accommodate the stop ring 4, which is connected to the support 6 by a screw passing through the ear ring 42. The cylinder 41 is located between the torsion spring 5 and the shaft 13, fixing the torsion spring 5 in its initial position. When the container pallet is loaded (unloaded), it first contacts the locking tongue 11. Under the action of the pallet, the locking tongue 11 rotates in the heading direction (counter-heading direction). The shaft 13 drives the torsion spring 5, pushing the lever 3 to rotate in the heading direction (counter-heading direction). The first plane 131 and the torsion spring 5 separate from the second plane 132 and the fourth plane 32 of the lever 3. The first arc surface 133 and the second arc surface 134 of the shaft 13 contact the torsion spring 5 and the fourth plane 32, respectively. At this time, the torsion spring 5 has a torsional torque. When the pallet passes smoothly (after loading into place), the torque is transmitted to the shaft 13 through the lever 3. The locking tongue 11 is centered and reset under the torsional torque of the torsion spring 5, realizing the vertical limitation of the pallet.

[0041] In summary, this invention provides a steering device for vertical limiting of container movement. It employs a stop block integrally formed with the locking tongue and shaft as the actuating part. A torsion spring, a paddle, and a stop ring form the torque transmission and reset parts. A steel bushing provides relatively wear-resistant rotational support for the shaft, and an anti-loosening component ensures stable shaft operation. The device has a compact structure and is relatively lightweight. This steering device requires no manual operation. During loading and unloading of the container pallet, the locking tongue drives the shaft to rotate, achieving relatively smooth avoidance through the cooperation of the planar and arc surfaces. The torsion spring simultaneously stores force. After the pallet passes, the torsion spring torque is transmitted back to the shaft through the paddle, driving the locking tongue to automatically center and reset. The vertical limiting surface of the locking tongue can complete the vertical limiting of the container, which can reduce manual operation and improve loading and unloading efficiency to a certain extent. This steering device can be directly integrated into the LRU assembly of the aircraft cargo hold, adapting to the cargo hold floor rail layout without occupying additional space. The overall transmission is relatively smooth and without jamming, the limit is relatively reliable, the structure has good stability and operational safety, and it can be adapted to various types of containers to meet the needs of efficient and lightweight air freight.
