Description

Technical Field

[0001] The utility model relates to a quick-release structure for a vertical tail, in particular to a quick-release structure for a vertical tail of an aircraft model. Background Art

[0002] Some existing aircraft models are relatively large in structure. To reduce the weight of the aircraft model, the materials used are relatively light foam plastics, etc., which are not resistant to collision. Therefore, if the whole aircraft needs to be transported outdoors for flight or shipped, the accommodation space requirements for the loading and transportation tools are relatively high, and it is easy to be bumped during transportation, resulting in model damage. Assembled aircraft models can solve the above problems. However, since the model has to withstand a large airflow pressure after takeoff, the assembled structure needs to ensure the stability of the structure during flight, and at the same time, the self-weight cannot be too heavy, otherwise it will affect the flight stability. Summary of the Utility Model

[0003] In order to overcome the above deficiencies, the utility model provides a quick-release structure for a vertical tail, which is quick to disassemble and assemble and has a stable structure.

[0004] To achieve this purpose, the structure adopted by the utility model is: a quick-release structure for a vertical tail, including a vertical tail and a tail section. One or more C-shaped hooks are provided at the bottom of the vertical tail. A connecting plate is provided on the tail section corresponding to the C-shaped hook. A bayonet is provided on the connecting plate. A convex block is provided at the end of the C-shaped hook, and the convex block cooperates with the bayonet.

[0005] The C-shaped hook is connected to the bottom of the vertical tail through a clamping block. The clamping block is a long strip-shaped groove body with a concave cross-section. The clamping block opens upward to clamp the bottom of the vertical tail, and the bottom of the clamping block is connected to the C-shaped hook.

[0006] The opening end of the C-shaped hook faces the end of the tail section.

[0007] A groove is provided at the top of the tail section, and the bottom of the vertical tail is arranged in the groove.

[0008] The bottom of the vertical tail is an inclined plane with one end high and the other end low.

[0009] The beneficial effects are as follows: The structure of the utility model is designed reasonably and ingeniously. The C-shaped hook and the connecting plate are used for buckling to realize the quick disassembly and assembly of the vertical tail. And because the opening of the C-shaped hook faces the end of the tail section, the airflow can push the vertical tail during flight, making the connection between the C-shaped hook and the connecting plate more firm. The structure of the C-shaped hook and the connecting plate is simple, and it has little influence on the weight of the tail section. Brief Description of the Drawings

[0015] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic way, so they only show the components related to the present utility model.

[0016] In the description of the utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0017] In the description of the utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" 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 directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements; the fixed connection can be welding or bonding. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0018] As Figure 1 shown in the vertical tail quick-release structure, including the vertical tail 1 and the tail 2. As Figure 2 shown, one or more C-shaped hooks 4 are provided at the bottom of the vertical tail 1. As Figure 3 shown, a connecting plate 5 is provided on the tail 2 corresponding to the C-shaped hook 4. A bayonet is provided on the connecting plate 5, and a convex block is provided at the end of the C-shaped hook 4. The convex block cooperates with the bayonet to realize the quick disassembly and assembly of the vertical tail 1 and the tail 2.

[0019] The C-shaped hook 4 is connected to the bottom of the vertical tail 1 through a clamping block 3. The clamping block 3 is a long strip-shaped groove body with a concave cross-section. The clamping block 3 opens upward to clamp the bottom of the vertical tail 1, and the bottom of the clamping block 3 is connected to the C-shaped hook 4.

[0020] The opening end of the C-shaped hook 4 faces the end of the tail 2.

[0021] A groove 6 is provided at the top of the tail 2, and the bottom of the vertical tail 1 is arranged in the groove 6.

[0022] The bottom of the vertical tail 1 is an inclined plane with one end high and the other end low. The horizontal height of the end far from the end of the tail 2 is high, and the horizontal height close to the end of the tail 2 is low.

[0023] The connection part between the bottom of the vertical tail 1 and the clamping block 3 is a convex block whose length and width protruding from the vertical tail 1 are smaller than the bottom surface of the vertical tail. When quick installation is carried out, the vertical tail 1 is inserted into the groove 6, and by moving, the C-shaped hook 4 bites with the bayonet on the connecting plate 5, realizing the connection between the vertical tail 1 and the tail 2. Since the opening of the C-shaped hook 4 faces the end of the tail 2, and the front end of the tail 2 is the windward side during the flight of the model, the bite between the C-shaped hook 4 and the connecting plate 5 can always maintain a firm bite. Since one end of the bottom of the vertical tail 1 is high and the other end is low, when the vertical tail is subjected to wind pressure, the tail 2 can play a supporting role to ensure the firmness of the connection. As Figure 4 shown, at the same time, since the C-shaped hook and the connecting plate 5 are hidden in the groove 6, it is also difficult to be impacted by external forces and break, and there is no airflow that can pour in, further ensuring the firmness of the connection. The quick-release structural components can be made of relatively light materials such as plastic, so the burden on the tail is small and it will not cause the deviation of the center of gravity during the flight of the model. When the vertical tail of the model aircraft can be assembled with a stable and reliable quick-release structure, during transportation, the vertical tail can be separated from the fuselage for transportation, reducing the space occupied by the whole machine and facilitating transportation.
