Description

Technical Field

[0001] This utility model relates to the field of barrier net technology, specifically a lightweight barrier net for air cargo. Background Technology

[0002] Cargo barrier nets are safety devices used in cargo transportation to prevent cargo from falling or going out of control during transport. They are typically made of mesh belts and joints. The mesh belts are made of non-metallic materials and are connected to metal joints by stitching. The metal joints are then connected to steel plates and the fuselage structure, transferring the load to the fuselage structure through the joints. Traditional cargo barrier nets have relatively thick wire harnesses to ensure their blocking strength, resulting in a heavy weight. To improve this situation, a lightweight cargo barrier net for air transport has been proposed.

[0003] As disclosed in the authorization announcement number CN218813317U, a barrier net for unloading ports includes A-post, B-post, and barrier net fixed to the ground. The A-post has an opening on the side opposite to the B-post. The A-post is equipped with a buffer mechanism at the opening and has a built-in winding mechanism. One side of the barrier net passes through the buffer mechanism and is fixed to the winding mechanism. It is driven by the winding mechanism to retract towards the opening and is built into the A-post. The B-post is equipped with multiple one-way limiting rings. The barrier net is stretched against the opening direction, and its side away from the winding mechanism is fixed with the rings. At least one safety restraint strip is laid on the surface of the barrier net. The buffer mechanism is used to buffer the impact force generated by hitting the barrier net.

[0004] Although it achieves the installation of multiple yellow safety restriction strips on the barrier net, painted with obvious yellow markings as bright stripe warnings, it can isolate personnel and production and logistics loading and unloading equipment. When the barrier net is in operation, the buffer can be activated to effectively absorb the impact force and avoid rigid collisions that could cause injury to people and vehicles.

[0005] However, this does not solve the problem that the existing barrier nets are not easy to lock and open in a coordinated manner, nor is it easy to provide multi-point support to prevent the barrier nets from detaching from the cargo warehouse, thus affecting the stability of the barrier nets during use. Utility Model Content

[0006] The purpose of this utility model is to provide a lightweight air cargo barrier net to solve the problems mentioned in the background art, such as the barrier net being inconvenient to lock and pull open in a coordinated manner, the barrier net being difficult to support at multiple points to prevent it from detaching from the cargo hold, and the barrier net being affected in terms of stability during use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a lightweight air cargo barrier net, comprising a cargo hold body and a barrier net body. The barrier net body is disposed inside the cargo hold body. A connecting ropes are disposed at each of the four corners of the barrier net body. Multiple sets of B connecting ropes are installed at equal intervals on both sides of the barrier net body. Multiple sets of plug-in seats are symmetrically installed at equal intervals on the inner wall of the cargo hold body. A nylon layer is disposed inside the barrier net body. A carbon fiber layer is disposed inside the nylon layer. A high-strength elastic wire layer is disposed inside the carbon fiber layer.

[0008] Preferably, the high-strength elastic wire layer is provided with a fine steel wire layer inside, and bolt assemblies are installed at the four corners inside the cargo body.

[0009] Preferably, each of the plug-in sockets is provided with a plug-in buckle inside, and the plug-in buckle is slidably connected to the plug-in socket, and the plug-in buckle is connected to the B connecting rope.

[0010] Preferably, limit rings are symmetrically installed on the side walls of the plug-in base, and plug-in pins are slidably installed inside the limit rings, with the plug-in pins slidably connected to the plug-in buckle.

[0011] Preferably, each of the plug-in pins is fitted with a spring, and the two ends of the spring are respectively connected to the limiting ring and the plug-in pin.

[0012] Preferably, each bolt assembly has a locking buckle on its exterior, and each locking buckle has a connecting post inside, with the connecting post threadedly connected to the locking buckle.

[0013] Preferably, each locking buckle on one side of the connecting post is provided with a connecting hook, and the connecting hook is threadedly connected to the locking buckle.

[0014] Preferably, the connecting hook can be hooked inside the connecting rope A, and the connecting post is movably connected to the bolt assembly.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the barrier net not only realizes convenient linkage locking and pulling to open the barrier net, which facilitates multi-point pulling and support of the barrier net to prevent the barrier net from separating from the warehouse, but also improves the stability of the barrier net during use.

[0016] After fitting the connecting post onto the bolt assembly and adjusting its angle, tighten the bolt assembly to secure the connecting post. Then, hook each of the four connecting ropes (A) onto the hooks and rotate the locking buckle. The locking buckle moves the hook towards the connecting post, pulling the A connecting ropes taut. With the synchronized action of the four hooks, the barrier net body is stretched open. The barrier net body's internal structure consists of a nylon layer, a carbon fiber layer, a high-strength elastic wire layer, and a fine steel wire layer. This four-layer structure ensures both structural strength and weight reduction, making it more lightweight. Next, take the snap fastener and insert it into the snap-fit ​​socket. The buckle drives the insertion post to move outward within the limiting ring. The insertion post compresses the spring. When the groove on the buckle surface moves to the insertion post position, the spring, under its elasticity, drives the insertion post to reset and insert into the groove, locking the buckle inside the insertion seat. This provides a lateral force to the B connecting rope, which in turn tightens the barrier net body, preventing it from detaching from the warehouse body due to insufficient connection points. This ensures the stability of the barrier net body during use and achieves convenient linkage locking, pulling, and opening of the barrier net. It facilitates multi-point pulling and support of the barrier net to prevent it from detaching from the warehouse, thus improving the stability of the barrier net during use.

[0026] Example 1

[0027] Please see Figure 1-5 An embodiment of this utility model is provided: a lightweight air cargo barrier net, including a cargo hold body 1 and a barrier net body 5. The barrier net body 5 is installed inside the cargo hold body 1. A connecting rope 4 is installed at each of the four corners of the barrier net body 5. Multiple sets of B connecting ropes 3 with equal spacing are installed on both sides of the barrier net body 5. Multiple sets of plug-in seats 2 with equal spacing are symmetrically installed on the inner wall of the cargo hold body 1. A nylon layer 10 is installed inside the barrier net body 5. A carbon fiber layer 11 is installed inside the nylon layer 10. A high-strength elastic wire layer 12 is installed inside the carbon fiber layer 11. A fine steel wire layer 13 is installed inside the high-strength elastic wire layer 12. Bolt assemblies 14 are installed at each of the four corners inside the cargo hold body 1.

[0028] Each plug-in socket 2 is equipped with a plug-in buckle 6 inside, and the plug-in buckle 6 is slidably connected to the plug-in socket 2, and the plug-in buckle 6 is connected to the B connecting rope 3;

[0029] Limiting rings 8 are symmetrically installed on the side walls of the plug-in socket 2. A plug-in post 9 is slidably installed inside the limiting ring 8, and the plug-in post 9 is slidably connected to the plug-in buckle 6. A spring 7 is fitted on the surface of the plug-in post 9, and the two ends of the spring 7 are respectively connected to the limiting ring 8 and the plug-in post 9.

[0030] All bolt assemblies 14 are provided with locking buckles 16 on the outside, and all locking buckles 16 are provided with connecting posts 15 inside, and the connecting posts 15 are threadedly connected to the locking buckles 16. All locking buckles 16 on one side of the connecting posts 15 are provided with connecting hooks 17 inside, and the connecting hooks 17 are threadedly connected to the locking buckles 16.

[0031] The connecting hook 17 can be hooked inside the connecting rope 4, and the connecting post 15 is movably connected to the bolt assembly 14;

[0032] The connecting post 15 is fitted onto the bolt assembly 14. After adjusting the angle of the connecting post 15, the connecting post 15 is fixed to the surface of the bolt assembly 14 by tightening the bolt assembly 14. Then, the connecting ropes A 4 are hooked onto the surface of the connecting hooks 17. The locking buckle 16 is rotated. With the threaded connection between the connecting post 15, the connecting hooks 17 and the locking buckle 16, the locking buckle 16 drives the connecting hooks 17 to move towards the connecting post 15. The connecting hooks 17 pull the connecting ropes A 4 tight. With the synchronous cooperation of the four sets of connecting hooks 17, the barrier net body 5 is pulled open. The internal structure of the barrier net body 5 consists of a nylon layer 10, a carbon fiber layer 11, a high-strength elastic wire layer 12, and a fine steel wire layer 13. These four structures ensure the structural strength of the barrier net while reducing its weight, making it lighter. Then, the plug buckle 6 is taken and plugged in. The buckle 6 is inserted into the inside of the plug-in seat 2. Under the sliding cooperation between the plug-in buckle 6 and the plug-in post 9, the plug-in buckle 6 drives the plug-in post 9 to move outward within the limiting ring 8. The plug-in post 9 compresses the spring 7. When the groove on the surface of the plug-in buckle 6 moves to the position of the plug-in post 9, under the elastic cooperation of the spring 7, the spring 7 drives the plug-in post 9 to reset and insert into the groove, thereby locking the plug-in buckle 6 inside the plug-in seat 2 to provide a lateral force to the B connecting rope 3. The B connecting rope 3 tightens the barrier net body 5 to prevent the barrier net body 5 from detaching from the cargo body 1 due to too few connection points, thus ensuring the stability of the barrier net body 5 during use. It realizes convenient linkage locking, pulling and opening of the barrier net, facilitates multi-point pulling support of the barrier net to prevent the barrier net from detaching from the cargo body, and improves the stability of the barrier net during use.

[0033] Work steps

[0034] The connecting post 15 is fitted onto the bolt assembly 14, and the connecting post 15 is fixed to the surface of the bolt assembly 14 by tightening the bolt assembly 14. Then, the connecting ropes A 4 are hooked onto the surface of the connecting hooks 17. The locking buckle 16 is rotated, and the locking buckle 16 drives the connecting hooks 17 to move towards the connecting post 15. The connecting hooks 17 pull the connecting ropes A 4, thereby pulling open the barrier net body 5. The internal structure of the barrier net body 5 consists of a nylon layer 10, a carbon fiber layer 11, a high-strength elastic wire layer 12, and a fine steel wire layer 13. These four structures ensure the structural strength of the barrier net while reducing its weight, making it lighter. Then, the connection is made. Insert the snap fastener 6 into the inside of the snap-fit ​​seat 2. The snap fastener 6 drives the snap-fit ​​post 9 to move outward within the limiting ring 8. The snap-fit ​​post 9 compresses the spring 7. When the groove on the surface of the snap fastener 6 moves to the position of the snap-fit ​​post 9, the spring 7 drives the snap-fit ​​post 9 to reset and insert into the groove, thereby locking the snap fastener 6 inside the snap-fit ​​seat 2. This provides a lateral force to the B connecting rope 3, which in turn tightens the barrier net body 5 to prevent the barrier net body 5 from detaching from the cargo hold body 1 due to too few connection points, thus ensuring the stability of the barrier net body 5 during use. The above is the complete usage of the lightweight barrier net for air cargo.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
