Description

Technical Field

[0001] The present invention relates to the technical field of air cargo restraint, and in particular to an air container unit restraint device. Background Art

[0002] In modern air transport, cargo systems on transport aircraft are comprised of a series of independent yet interrelated devices, including those for transport, guidance, and restraint. Restraint devices are crucial for reliably restraining the forward, backward, left, right, and upward movement of containerized units. With the advancement of standardization of containerized units, restraint requirements have become clear industry standards. The current mainstream approach is to install standard-compliant restraint devices on cargo aircraft floors to effectively restrain containerized units. However, existing technologies still face technical challenges that need to be addressed. In the front and rear restraint links, it is necessary to ensure the reliability of the restraint to prevent displacement of the container unit during transportation, while also meeting the need for smooth transfer of the pallet during loading and unloading. These two requirements are often difficult to balance in actual operation, and traditional restraint devices are unlikely to meet both requirements simultaneously. Furthermore, while the use of complex automated restraint mechanisms can achieve the restraint function to a certain extent, they suffer from high energy consumption and equipment costs. Simple manual restraint methods, on the other hand, suffer from cumbersome operation and low work efficiency. Therefore, it is necessary to design an aviation container unit restraint device to address the aforementioned issues.

[0003] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood based on specific circumstances.

[0027] The technical solutions of the present invention will be described clearly and completely below with reference to specific embodiments. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0028] See also Figures 1-10 The present invention provides an aviation container unit limiting device, comprising: It includes a base 1, a lock body 2, a support 3, a torsion spring 1 4, a shaft 1 5, a torsion spring 2 6 and a shaft 2 7; Axis 1 5 and axis 2 7 are both fixedly mounted on the base 1 , the lock body 2 is rotatably mounted on axis 2 7 , the support 3 is rotatably mounted on axis 1 5 , the torsion spring 1 4 is sleeved on axis 1 5 , and the torsion spring 2 6 is sleeved on axis 2 7 .

[0029] When the container unit 8 is loaded, the lock body 2 and the support 3 are in a flat state and are lower than the bottom surface of the container unit 8. The container unit 8 can move smoothly over the limiting device without removing the limiting device. When the container unit 8 is moved into place, the lock body 2 is manually lifted and the lock body rotates around the axis 2 7. At the same time, the support 3 moves with the lock body 2 under the action of the torsion spring 1 4. When the lock body 2 moves to an upright state, the card platform 301 of the support 3 falls into the card slot 201 of the lock body 2, realizing the limitation of the lock body 2. Under the joint action of the support 3 and the torsion spring, the lock body 2 remains in an upright state, realizing the limitation of the container unit 8.

[0030] When the container unit 8 needs to be unloaded, the support 3 is manually pressed downward to disengage the card platform 301 of the support 3 from the card slot 201 of the lock body 2. At this time, the lock body 2 falls clockwise under the action of the torsion spring 26 and presses the support 3 so that it will not lift up. After the lock body 2 falls, its height will be lower than the bottom surface of the container unit 8, ensuring that the container unit 8 can pass smoothly.

[0031] Specifically, one end of torsion spring 1 4 is fixedly connected to base 1 , and the other end of torsion spring 1 4 is pressed on support 3 , one end of torsion spring 2 6 is fixedly connected to base 1 , and the other end of torsion spring 2 6 is pressed on lock body 2 . It should be noted that this facilitates the resetting of lock body 2 and support 3 .

[0032] Specifically, the top of the base 1 contacts the container unit 8, and the inner side of the lock body 2 abuts against the container unit 8. The lock body 2 includes a self-standing part and a lock tongue, and both the self-standing part and the lock tongue abut against the container unit 8. It should be noted that the vertical and front and rear movement limits of the container unit 8 are realized.

[0033] Specifically, the lock body 2 is provided with a card slot 201 that cooperates with the support 3 , and the support 3 is provided with a card platform 301 that cooperates with the lock body 2 . It should be noted that the support 3 supports the lock body 2 .

[0034] Working principle: S1: The aviation container unit limit device is fixed to the floor through the base 1. When the container unit 8 is loaded, the limit device is in the loading working state. Figure 4 As shown, the lock body 2 and the support 3 are both in a flat state, and the container unit 8 passes over the upper part of the limit device; S2: When the container unit 8 moves into place, the result is as follows Figure 5 As shown, the lock body 2 is manually lifted, and the lock body 2 rotates around the axis 2 7. At the same time, the force of the lock body 2 pressing on the support 3 disappears. Under the action of the torsion spring 1 4, the support 3 rotates clockwise around the axis 1 5 with the lock body 2. The result is as shown in FIG. Figure 6As shown, when the lock body 2 moves to the upright state, the card platform 301 of the support 3 falls into the card slot 201 of the lock body, and the support 3 supports the lock body 2. After the external force is removed, the lock body 2 has a clockwise rotation trend under the action of the torsion spring 2 6. At the same time, the support 3 has a counterclockwise rotation trend under the action of the torsion spring 1 4. The two are pressed together under the action of opposite forces to ensure that the lock body 2 is in the upright state. The result is as shown in FIG. Figure 7 As shown, the rearward movement of the container unit 8 can be limited at this time, and the result is as follows Figure 8 As shown; S3: At the same time, lift the lock body 2 of the rear limit device to make it stand upright. When the next container unit 8 moves into position, the forward limit of the container unit 8 can be realized. Figure 9 As shown; S4: When the container unit 8 needs to be unloaded, the support 3 is manually pressed down, such as Figure 10 As shown, the card platform 301 of the support 3 is disengaged from the card slot 201 of the lock body 2. The lock body 2 rotates clockwise around the axis 2 7 under the action of the torsion spring 2 6 and falls down. At the same time, the rear part of the lock body 2 sinks and presses on the support 3. Since the torque of the torsion spring 2 6 is much greater than that of the torsion spring 1 4, the lock body 2 presses the support 3 into the base 1. Finally, under the action of the torsion spring 2 6, the lock body 2 and the support 3 remain in a flat state. The result is as shown in FIG. Figure 2 As shown, at this time, the container unit 8 is released from the restraint and can move backward.
