Description

Technical Field

[0001] This utility model relates to the technical field of wing connection equipment, specifically a connection structure for fixing wings. Background Technology

[0002] The wing fixing connection structure is a key component for achieving a rigid connection between the aircraft wing and fuselage. Its core function is to safely transfer the aerodynamic loads borne by the wing to the fuselage, while ensuring the structural stability and integrity of the wing and fuselage under various flight conditions. This type of structure is one of the most load-bearing and complex parts of the aircraft structure, directly related to flight safety. However, existing wing fixing connection structures have some shortcomings, such as:

[0003] Application No.: CN202121011703.6 describes a quick-fixing connection device for wings and fusels. This device can quickly fix wings and fusels, and the entire process of insertion and disassembly is convenient and quick, which can be completed without carrying any disassembly and assembly tools. The fixed connection between wings and fusels is stable and reliable. However, in actual use, only two sets of rods are used to fix the wings, which may cause instability of the fuselage when the wings are fixed.

[0004] Therefore, we propose a connecting structure for wing fixing to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a connecting structure for fixing wings, so as to solve the problem mentioned in the background art that most wing fixing structures on the market currently only use rods to fix the wings, which may cause instability of the fuselage when the wings are fixed.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a connecting structure for fixing an airfoil, comprising an airfoil body and airfoil bodies disposed on the left and right sides of the airfoil body, wherein a connecting seat is provided on the outer side of the airfoil body and the connecting seat is fixedly connected to the airfoil body;

[0007] A connecting mechanism is provided on the outside of the connecting seat, and the connecting mechanism includes two sets of connecting rods. A limiting seat is provided on the outside of the connecting rods. A fixing plate is provided on the outside of the limiting seat, and the fixing plate is fixedly attached to the wing body. A snap-fit ​​seat is provided on the outside of the connecting rod, and a connector is connected to the outside of the snap-fit ​​seat. A fixing frame is snapped onto the outside of the snap-fit ​​seat, and the fixing frame is fixedly connected to the connector.

[0008] The outer side of the fixed frame is fixedly connected to the wing body, and a support mechanism is provided inside the wing body.

[0009] By setting up a connecting mechanism, two sets of connecting rods can support and fix the inside of the wing body through fixing plates, and fix the outside of the wing through fixing frames. This allows the wing body to be fixed to the fuselage body through the two sets of components on the inside and outside, making the connection and installation of the fuselage body and the wing body more secure, thus increasing the stability of the equipment during installation.

[0010] As a preferred technical solution of this utility model, the outer side of the body is fixedly connected to the connecting seat, and the outer side of the connecting seat is provided with a fixing seat, and the outer side of the fixing seat is fixedly connected to two sets of connecting rods.

[0011] The above technical solution enables the connecting seat to be more stable when fixing the two sets of connecting rods in the installation mechanism, thereby increasing the stability of the equipment during operation.

[0012] As a preferred technical solution of this utility model, the bottom of the fixing seat is provided with two sets of riveting bolts, and the fixing seat is fixedly connected to the wing body through the riveting bolts. Furthermore, a tail rod is provided on the outside of the connecting seat, and the tail rod passes through the fixing plate and is fixedly connected to the fixing frame.

[0013] The above technical solution enables the tail boom to work with two sets of connecting rods to fix the fixing plate and the wing body, making the structure more stable when fixing and installing the wing body, thereby increasing the stability of the equipment during operation.

[0014] As a preferred technical solution of this utility model, the bottom of the fixing frame is provided with two sets of fixing bolts, and the fixing frame is fixedly connected to the connector through the fixing bolts, and the connecting rod is fixedly connected to the outer side of the wing body through the snap-fit ​​seat.

[0015] The above technical solution enables the fixed frame to be more stable when connected to the connecting rod, thereby increasing the stability of the equipment during operation and the firmness of the equipment during installation.

[0016] As a preferred technical solution of this utility model, the wing body is fixedly connected to the support mechanism, and the support mechanism includes two sets of first fixing rings, each of which is fixedly connected to a set of connecting rods. A second fixing ring is fixedly connected to the outside of the connecting rod, and a support rod is provided on the outside of the first and second fixing rings. A fixed fulcrum is connected to the outside of the support rod, and a fixed plate is provided at the bottom of the fixed fulcrum. The fixed plate is fixedly connected to the inside of the wing body.

[0017] The above technical solution enables the support mechanism to work with the connecting mechanism to fix the wing body, thereby reducing the weight of the wing body and effectively preventing the wing body from becoming unstable during flight.

[0018] As a preferred technical solution of this utility model, the outer side of the connecting rod is fixedly connected to the fixing plate through the limiting seat, and a support mechanism is provided between every two sets of fixing plates.

[0019] The above technical solution enables the connecting rod to limit the position of the fixing plate by the limiting seat when it is connected to the fixing plate, thereby increasing the stability of the equipment during installation.

[0020] As a preferred technical solution of this utility model, the bottom of the wing body is provided with a slot, and the bottom of the fixing frame is provided with a block, and the bottom of the fixing frame is fixed to the slot at the bottom of the wing body by the block.

[0021] The above technical solution enables the outer side of the wing body to be more stable when it is fixedly connected to the fixed frame, thereby increasing the stability of the equipment during installation.

[0022] Compared with the prior art, the beneficial effects of this utility model are: by setting the connecting mechanism, the two sets of connecting rods can support and fix the inside of the wing body through the fixing plate, and fix the outside of the wing through the fixing frame. When the wing body is connected and fixed to the fuselage body, it can be fixed by the two sets of components on the inner and outer sides, so that the fuselage body can be more firmly connected and installed with the wing body, thereby increasing the stability of the device during installation.

[0023] Furthermore, the tail boom, in conjunction with two sets of connecting rods, can fix the fixing plate and the wing body, making the structure more stable when fixing and installing the wing body, thereby increasing the stability of the equipment during operation.

[0024] Furthermore, the support mechanism, in conjunction with the connecting mechanism, can secure the wing body, effectively preventing instability during flight while reducing the weight of the wing body. Attached Figure Description
