Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of aircraft parking, specifically to an aircraft ground parking wheel chock mechanism. Background Technology
[0002] Aircraft wheel chocks are rubber or metal blocks placed in front of and behind the aircraft tires when the aircraft is parked. Their main function is to stabilize and stop the main wheels, preventing abnormal slippage. Wheel chocks are needed for the maintenance of aircraft pulleys and for parking the aircraft. Most wheel chocks are made of rubber or metal, and these materials offer a long service life and are relatively easy to use.
[0003] The Chinese patent announcement with publication number CN220363465U discloses a conveniently stackable aircraft pulley maintenance wheel device. Its key technical features include: two sets of wheel bodies, each set of wheel bodies having multiple sets of weight-reducing cavities, both ends of the wheel body being provided with cover plates, the outer ring of the wheel body being provided with a rubber layer, and a nylon rope being provided in the through hole.
[0004] In the above solution, the front and rear sides of the machine wheel are blocked by two main bodies of the wheel respectively, which has the following disadvantages: the two main bodies of the wheel cannot be connected when in use, and they are prone to displacement when parked. Utility Model Content
[0005] The purpose of this invention is to provide an aircraft ground parking wheel stop mechanism to solve the problem that the two wheel stops cannot be connected during use and are prone to displacement when parked.
[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: an aircraft ground parking wheel stop mechanism, comprising two cover plates, the two cover plates being fixed to the front and rear sides of two wheel stop bodies respectively, slots being provided on the outer sides of the two cover plates respectively, two U-shaped rods being provided between the two wheel stop bodies, the two ends of the two U-shaped rods being slidably inserted into the two slots respectively, both wheel stop bodies being triangular in shape, the sides of both wheel stop bodies being provided with a 45-degree bevel, and several protrusions being provided on the left and right sides of the outer walls of both wheel stop bodies.
[0007] Preferably, each end of the two U-shaped rods is fixed with a first magnet, and the interior of the two slots is fixed with a second magnet, and the two second magnets are magnetically attracted to the two first magnets respectively.
[0008] Preferably, the outer walls of both of the wheel bodies are provided with a rubber layer.
[0009] Preferably, each of the two wheel bodies has a connecting hole on its front side, and a connecting rope is provided inside each of the two connecting holes.
[0010] Preferably, a first weight-reducing hole is provided on the front side of each of the two wheel bodies, and two second weight-reducing holes are provided on the front side of each of the two wheel bodies.
[0011] Preferably, a first reflective sticker is fixed to the outer side of both cover plates, and a second reflective sticker is fixed to the left and right sides of the outer walls of both rubber layers.
[0012] Compared with existing technologies, the aircraft ground parking wheel chock mechanism that adopts the above technical solution has the following beneficial effects:
[0013] 1. In use, the coordinated action of the cover plate, the main body of the wheel stop, the slot, the U-shaped rod and the boss helps to limit and block the aircraft wheels. At the same time, it can connect the two wheel stop bodies, which can improve their ability to block the wheels and effectively share greater pressure, thereby improving the overall safety.
[0014] Second, during use, the U-shaped rod is secured by the magnetic attraction between the first and second magnets, preventing it from detaching from the slot, thus improving stability and ensuring a tight connection between the two wheel chocks, providing a continuous and reliable stopping force for the aircraft. This reduces the impact force between the aircraft wheel and the wheel chock body, protecting both from damage and allowing them to withstand long-term friction, reducing wear and extending the service life of the wheel chock body. Operators can lift, move, and place the wheel chock body in designated positions by holding the connecting rope, improving operational efficiency.
[0015] Third, during use, the first and second weight-reducing holes effectively reduce the weight of the wheel stop body, making it easier and less strenuous for workers to move and install the wheel stop, improving work efficiency, and reducing material usage, thus directly lowering raw material costs. These reflective stickers reflect ambient light, making the wheel stop mechanism clearly visible from a distance. Attached Figure Description

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0022] like Figures 1-4 As shown, an aircraft ground parking wheel stop mechanism includes two cover plates 1, which are fixed to the front and rear sides of two wheel stop bodies 2 respectively. The outer sides of the two cover plates 1 are respectively provided with slots 3. Two U-shaped rods 4 are provided between the two wheel stop bodies 2. The two ends of the two U-shaped rods 4 are slidably inserted into the two slots 3 respectively. Both wheel stop bodies 2 are triangular in shape. The sides of both wheel stop bodies 2 are provided with 45-degree inclined planes. Several protrusions 5 are provided on the left and right sides of the outer walls of both wheel stop bodies 2.
[0023] In use, the staff first precisely places two triangular wheel chock bodies 2 with 45-degree beveled sides on the front and rear sides of the aircraft's main wheel, respectively. When the wheel shifts and presses against the wheel chock due to various reasons, the 45-degree slope plays a clever role. It ensures that the downward pressure generated by the wheel on the wheel chock is converted into a force that provides sufficient static friction, thereby effectively resisting the horizontal thrust brought by the wheel. This feature enhances the stability of the wheel chock and effectively prevents dangerous situations such as wheel chock slippage and wheel-wheel slippage. It provides a solid guarantee for the safety of the aircraft when parked on the ground. At the same time, the protrusion 5 further enhances the anti-slip performance of the wheel chock.
[0024] After the staff completes the placement of the wheel chock body 2, they accurately insert the two ends of the U-shaped rod 4 into the slots 3 opened on the outside of the two cover plates 1. This operation connects the two wheel chock bodies 2 together to form a stable whole. In the process of preventing the aircraft from sliding, this connection method provides more reliable support, especially in windy weather or on ground with a large slope. It effectively avoids the sliding or displacement of a single wheel chock body 2. At the same time, the connected whole structure can better distribute the pressure when subjected to the weight of the aircraft and external forces, making the whole structure more robust and improving safety.
[0025] Through the coordinated action of the cover plate 1, the main body of the wheel stop 2, the slot 3, the U-shaped rod 4 and the boss 5, it is beneficial to limit and block the aircraft wheels. At the same time, it can connect the two wheel stop bodies 2, which can improve their ability to resist the wheels and effectively share greater pressure, thereby improving the overall safety.
[0026] like Figures 1-3 As shown, both ends of the two U-shaped rods 4 are fixed with first magnets 6, and the interiors of the two slots 3 are respectively fixed with second magnets 7, and the two second magnets 7 are magnetically attracted to the two first magnets 6 respectively.
[0027] In use, when the staff inserts the U-shaped rod 4 into the two slots 3, the first magnet 6 and the second magnet 7 attract each other to fix the U-shaped rod 4, preventing it from coming out of the slot 3, thus improving stability and ensuring that the two wheel bodies 2 are tightly connected, continuously providing reliable blocking force for the aircraft.
[0028] like Figure 1 , Figure 2 and Figure 4 As shown, the outer walls of the two main bodies 2 of the two wheel stops are provided with rubber layers 8, and the front sides of the two main bodies 2 of the two wheel stops are provided with connecting holes 9, and the interiors of the two connecting holes 9 are provided with connecting ropes 10.
[0029] During use, the rubber layer 8 is made of hydrogenated nitrile rubber, which has good elasticity and flexibility. It effectively cushions the impact when the machine wheel contacts the wheel body 2, reducing the impact force between them and protecting both from damage. It also withstands long-term friction, is not easily worn, and extends the service life of the wheel body 2. The connecting rope 10 is made of high-strength polyester fiber, which has advantages such as high strength, wear resistance, and tensile strength. It can withstand significant tension, ensuring it will not break when picking up or placing the wheel body 2. Workers can lift, move, and place the wheel body 2 to a designated position by holding the connecting rope 10, improving operational efficiency.
[0030] like Figures 1-4 As shown, the front sides of the two wheel chock bodies 2 are provided with first weight reduction holes 11, and the front sides of the two wheel chock bodies 2 are provided with two second weight reduction holes 12. The outer sides of the two cover plates 1 are fixed with first reflective stickers 13, and the left and right sides of the outer walls of the two rubber layers 8 are fixed with second reflective stickers 14.
[0031] In use, the first weight-reducing hole 11 and the second weight-reducing hole 12 effectively reduce the weight of the wheel stop body 2, making it easier and less strenuous for workers to handle and install the wheel stop, improving work efficiency, and reducing material usage, thus directly lowering raw material costs. The first reflective sticker 13 and the second reflective sticker 14 have important safety warning functions. In low-light environments, such as at night or in low-visibility weather conditions, these reflective stickers can reflect ambient light, making the wheel stop mechanism clearly visible from a distance.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
