[0002] As a key piece of equipment used to transport aviation equipment, components, or tools, the performance of aviation trailers directly affects the efficiency, safety, and reliability of aviation ground operations. Existing aircraft trailers often employ single-position or simple clamping methods for securing equipment, making it difficult to achieve precise and stable fixation for aircraft of varying sizes. This can easily lead to insecure securing, causing equipment to shake or collide during transport, potentially damaging the equipment and posing safety hazards. Utility Model Content

[0003] The purpose of this utility model is to provide an aircraft trailer arm assembly and trailer to solve the defect that existing aircraft trailer arm assemblies and trailers are not easy to fix.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an aviation trailer arm assembly and a trailer, including a trailer platform; The vehicle body has a through groove inside, and a fixing plate is fixed in the middle of the through groove. Wheels are installed on both sides of the bottom end of the vehicle body. A pull rod is fixed on one side of the vehicle body. Fixing structures are provided on both sides of the top end of the vehicle body. The fixing structure includes a first side plate fixed to one side of the top end of the vehicle body, and a second side plate fixed to the other side of the top end of the vehicle body. A handle is fixed to one side of the first side plate and the second side plate. Support rollers are installed on both sides of the fixing plate inside the through groove. A first sliding groove is provided on one side of the top end of the fixing plate, and a second sliding groove is provided on the other side of the top end of the fixing plate. A connecting structure is fixed on the side of the vehicle panel away from the tie rod.

[0005] Preferably, threaded rods are installed inside the first and second slides, and movable blocks are installed on the outer side of the threaded rods. Threaded grooves are provided on the outer side of the threaded rods inside the movable blocks. Guide blocks are fixed on both sides of the movable blocks, and guide grooves are provided on the outer side of the guide blocks. A first rotating block is installed at the top of the movable block, and a locking block is fixed on one side of the first rotating block. Fixed blocks are fixed at one end of the threaded rods on both sides of the vehicle plate.

[0006] Preferably, the first side panel and the second side panel are symmetrically distributed at the top of the vehicle panel, and the handles are symmetrically distributed on one side of the first side panel and the second side panel, respectively.

[0007] With the above structure, the first and second side plates are symmetrically distributed at the top of the vehicle plate during use, which can effectively block the lateral movement of the aviation equipment and prevent the equipment from shifting laterally due to inertia during the start-up, stop or turn of the trailer.

[0008] Preferably, the support rollers are equally spaced on both sides of the fixed plate inside the through groove, the support rollers are rotatably connected inside the through groove, and the first slide groove and the second slide groove are symmetrically distributed at the top of the fixed plate.

[0009] With the above structure, the support rollers are evenly distributed and rotatably connected on both sides of the fixed plate inside the through groove during use. During the movement of the trailer, the support rollers will rotate with the movement of the equipment, converting the sliding friction between the equipment and the vehicle plate into rolling friction, reducing the friction between the bottom of the equipment and the vehicle plate, and reducing the wear on the surface of the equipment and the vehicle plate.

[0010] Preferably, the movable block and the threaded rod are connected by a threaded groove, the guide blocks are symmetrically distributed on both sides of the movable block, the guide blocks are slidably connected to the vehicle plate by a guide groove, and the locking block is arranged in an "L" shape.

[0011] With the above structure, the guide block and guide groove provide a stable trajectory constraint for the movement of the moving block during use, effectively preventing the moving block from rotating, tilting or deviating during the movement with the threaded rod, and ensuring that the moving block always moves smoothly along a straight line.

[0012] Preferably, the connecting structure includes a first support plate fixed to the side of the vehicle plate away from the tie rod, a second support plate fixed to one side of the first support plate, a hinge shaft installed between the first and second support plates, a locking nut installed on the outer side of the hinge shaft on one side of the first and second support plates, a second rotating block fixed to the outer side of the hinge shaft, rubber sleeves installed on the outer side of the hinge shaft at both ends of the second rotating block, a connecting plate fixed to one side of the second rotating block, and mounting holes provided inside the connecting plate.

[0013] Preferably, the first support plate and the second support plate are symmetrically distributed on the side of the vehicle plate away from the tie rod, the first support plate and the second support plate are arranged in an "L" shape, and the locking nut is threadedly connected to the hinge shaft.

[0014] With the above structure, the locking nut and the hinge shaft are threaded together during use. The operator can loosen the locking nut to release the rotation constraint of the hinge shaft, so that the hinge shaft can drive the second rotating block and the connecting plate to flexibly adjust the angle to adapt to the connection angle requirements of different external equipment.

[0015] The advantages of the aviation trailer arm assembly and trailer provided by this utility model are as follows: By setting a fixed structure and using a rotating connection design with equally spaced support rollers, the sliding friction between the equipment and the vehicle platform is converted into rolling friction, reducing wear during equipment placement and movement. The threaded connection between the threaded rod and the moving block, combined with the sliding guidance of the guide block and the guide groove, allows the clamping block to clamp the equipment from both sides. The self-locking characteristic of the threaded connection is used to maintain the clamping force continuously, effectively preventing the equipment from falling off during trailer driving, turning, or braking, and greatly improving the safety of the equipment during transportation. By incorporating a connecting structure, the rubber sleeve on the outside of the hinge shaft effectively absorbs vibration and impact when the trailer moves or the connecting part is subjected to force, preventing rigid collisions and friction between the hinge shaft and the support plate, reducing mechanical damage to components, providing good protection for the hinge shaft, and extending the service life of the hinge shaft and related connecting parts.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5 The present invention provides an aviation trailer arm assembly and trailer, including a trailer platform 1.

[0020] Reference Figures 1-5 As shown, the interior of the vehicle plate 1 has a through groove 2, and a fixing plate 3 is fixed in the middle of the through groove 2. Wheels 4 are installed on both sides of the bottom of the vehicle plate 1. A pull rod 5 is fixed on one side of the vehicle plate 1. Fixing structures 6 are provided on both sides of the top of the vehicle plate 1. The fixing structure 6 includes a first side plate 601 fixed to one side of the top of the vehicle plate 1, and a second side plate 602 fixed to the other side of the top of the vehicle plate 1. A handle 603 is fixed to one side of the first side plate 601 and the second side plate 602. Support rollers 604 are installed on both sides of the fixing plate 3 inside the vehicle plate 1. A first sliding groove 605 is provided on one side of the top of the fixing plate 3, and a second sliding groove 606 is provided on the other side of the top of the fixing plate 3. Threaded rods 607 are installed inside the first sliding groove 605 and the second sliding groove 606. A moving block 608 is installed on the outside of the threaded rod 607. A threaded groove 609 is provided on the outside of the threaded rod 607 inside the moving block 608. Guide blocks 610 are fixed on both sides of the moving block 608. A guide groove 611 is provided on the outer side of the block 610. A first rotating block 612 is installed on the top of the moving block 608. A locking block 613 is fixed on one side of the first rotating block 612. A fixing block 614 is fixed at one end of the threaded rods 607 on both sides of the vehicle plate 1. The first side plate 601 and the second side plate 602 are symmetrically distributed on the top of the vehicle plate 1. The handles 603 are symmetrically distributed on one side of the first side plate 601 and the second side plate 602 respectively. The support rollers 604 are equally spaced on both sides of the fixed plate 3 inside the through groove 2. The support rollers 604 are rotatably connected inside the through groove 2. The first sliding groove 605 and the second sliding groove 606 are symmetrically distributed on the top of the fixed plate 3 respectively. The moving block 608 and the threaded rod 607 are threadedly connected through the threaded groove 609. The guide blocks 610 are symmetrically distributed on both sides of the moving block 608. The guide blocks 610 and the vehicle plate 1 are slidably connected through the guide groove 611. The locking block 613 is arranged in an "L" shape.

[0021] With the support rollers 604 evenly spaced and rotating, the rolling friction reduces the frictional resistance between the equipment and the fixed plate during the placement or movement of the aviation equipment, thus reducing wear during placement. The operator drives the threaded rod 607 to rotate by rotating the fixed block 614 at one end of the threaded rod 607. The moving block 608 forms a threaded connection with the threaded rod 607 through the internal threaded groove 609, so that the rotational motion of the threaded rod 607 is converted into the linear motion of the moving block 608. The guide blocks 610 on both sides of the moving block slide along the guide groove 611 on the vehicle plate to ensure the stability of the movement of the moving block 608 and avoid deviation. This causes the first rotating block 612 at the top of the moving block 608 to drive the "L"-shaped locking block 613 to move synchronously. The locking blocks 613, which are symmetrically distributed on both sides, gradually approach and clamp from both sides of the equipment. The self-locking characteristic of the moving block 608 and the threaded connection maintains the clamping force, so that the locking blocks 613 can firmly fix the aviation equipment and prevent the equipment from shaking or falling off during the movement of the trailer.

[0022] Reference Figures 1-3 As shown, a connecting structure 7 is fixed on the side of the vehicle plate 1 away from the tie rod 5. The connecting structure 7 includes a first support plate 701 fixed on the side of the vehicle plate 1 away from the tie rod 5, a second support plate 702 fixed on one side of the first support plate 701, a hinge shaft 703 installed between the first support plate 701 and the second support plate 702, a locking nut 704 installed on the outside of the hinge shaft 703 on one side of the first support plate 701 and the second support plate 702, a second rotating block 705 fixed on the outside of the hinge shaft 703, rubber sleeves 706 installed on the outside of the hinge shaft 703 at both ends of the second rotating block 705, a connecting plate 707 fixed on one side of the second rotating block 705, and an installation hole 708 provided inside the connecting plate 707. The first support plate 701 and the second support plate 702 are symmetrically distributed on the side of the vehicle plate 1 away from the tie rod 5, and the first support plate 701 and the second support plate 702 are arranged in an "L" shape. The locking nut 704 is threadedly connected to the hinge shaft 703.

[0023] The hinge shaft 703 passes through the first support plate 701 and the second support plate 702, which facilitates the axial pressure generated by the threaded connection between the locking nut 704 and the hinge shaft 703, thus fixing the hinge shaft 703 to the support plate. When the trailer moves or the connection part is subjected to force, the rubber sleeve 706 on the outside of the hinge shaft 703 can absorb some vibration and impact force, reduce wear caused by rigid contact, and at the same time protect the hinge shaft 703 and extend the service life of the component. The mounting hole 708 inside the connecting plate 707 can be fixed to external equipment through bolts and other connecting parts.
