[0025] The present invention will now be described in detail with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can be combined with each other.

[0026] like Figure 1-5As shown, an adjusting locking mechanism for setting the installation angle of components according to the present invention includes a pin assembly, a locking structure assembly, and a main support 7; the pin assembly includes an anti-detachment pin 1, a key 2, and a main rotating shaft 3; the locking structure assembly includes a first clamp 4, a second clamp 5, and a locking support 6; the main support 7 is provided with the locking support 6; the second clamp 5 is fixed on the locking support 6; the second clamp 5 is connected to the first clamp 4 to form a through hole; the main support 7 is provided with a first hole; the main rotating shaft 3 passes through the first hole and the through hole; the main rotating shaft 3 is provided with a second hole, a groove, and a knurled portion; the anti-detachment pin 1 is installed in the second hole; the key 2 is provided in the groove.

[0027] The main support 7 and the locking support 6 are connected by bolts; the first clamp 4 and the second clamp 5 are connected by bolts; the radius of the through hole formed by the connection between the second clamp 5 and the first clamp 4 is the same as the radius of the main rotating shaft 3; the length of the concave arc of the first clamp 4 is less than that of a semicircle; the knurled part of the main rotating shaft 3 is located on the contact surface between the main rotating shaft 3 and the first clamp 4 and the second clamp 5; the main support 7 is provided with several ribs; the ribs include trapezoidal ribs, triangular ribs and rectangular ribs; the main support 7 is U-shaped.

[0028] The main support 7 is used to provide an installation position for the locking support 6, and to provide additional installation space and installation position adjustment range.

[0029] The first clamp 4 and the second clamp 5 have a structure with an inner concave arc. The first clamp 4 and the second clamp 5 are connected to form a through hole, and the first clamp 4 and the second clamp 5 are connected and tightened by bolts to lock the main rotating shaft 3.

[0030] The diameter and length of the main rotating shaft 3 can be adjusted according to assembly needs to accommodate components of different sizes. The mounting position of the main rotating shaft 3 can be adjusted axially as needed to adapt to various installation scenarios.

[0031] The key 2 in the groove of the main rotating shaft 3 is used to transmit torque.

[0032] The anti-detachment pin 1 on the second hole of the main rotating shaft 3 is used to transmit axial force.

[0033] The main support 7 is provided with a number of ribs to enhance the strength of the structure; the ribs include, but are not limited to, trapezoidal ribs, triangular ribs and rectangular ribs.

[0034] The main support 7 is U-shaped, providing additional installation space and adjustment range for the installation position. It is understood that the main support is not limited to a U-shape; in other embodiments, any structure of the main support that provides additional installation space and adjustment range for the installation position is acceptable.

[0035] The knurled portion of the main rotating shaft 3 is used to increase the contact force between the main rotating shaft and the first clamp 4 and the second clamp 5.

[0036] In some embodiments, the depth of the knurled portion of the main rotating shaft 3 is 0.2 mm, but it can be adjusted according to the actual use scenario.

[0037] In this invention, the main rotating shaft 3 has Hertz contact with the first clamp 4 and the second clamp 5. After the mechanism is locked, the contact pressure between the main rotating shaft 3 and the first clamp 4 and the second clamp 5 is:

[0038]

[0039] Wherein, F is the total preload of the four sets of bolts that are matched with the first clamp 4 and the second clamp 5;

[0040] L is the axial contact length between the main rotating shaft 3 and the locking structure assembly;

[0041] ρ1 and ρ2 are the radii of curvature of the main rotation axis 3 and the first clamp 4 and the second clamp 5, respectively;

[0042] μ1 and μ2 are the Poisson's ratios of the materials of the main rotating shaft 3 and the locking structure assembly, respectively.

[0043] E1 and E2 are the material elastic moduli of the main rotating shaft 3 and the locking structure assembly, respectively.

[0044] The frictional force at the contact surface can then be calculated:

[0045] f = σ * μ fric

[0046] σ is the contact pressure between the main rotating shaft 3 and the first clamp 4 and the second clamp 5;

[0047] μ fric The coefficient of friction of the contact surfaces;

[0048] Since this locking mechanism is designed for underwater vehicles, small aircraft, and other applications where the components to be installed are often subjected to considerable torque, and the locking performance of this mechanism is determined by the frictional force of the contact surfaces, the dimensions of the structure can be calculated and verified during the design phase based on the above formula.

[0049] One embodiment of this invention is applied to an underwater vehicle, which can be a vehicle with horizontal or vertical wings but does not require active adjustment, providing wing mounting position and wing angle adjustment functions. In use, the horizontal or vertical wings of the underwater vehicle are connected to the vehicle body through this invention. Furthermore, through this invention, the angle of the horizontal or vertical wings can be adjusted, thereby providing different horizontal or lateral forces to the underwater vehicle, achieving the effect of adjusting the underwater vehicle's attitude and overcoming flow resistance in a certain direction.

[0050] like Figure 6 As shown, an embodiment of the adjusting locking mechanism for setting the installation angle of components according to the present invention is as follows: the main support 7 and the locking support 6 are connected by bolts; then the main rotating shaft 3 is inserted from the first hole of the locking support 6, and the installation angle is adjusted so that the anti-detachment pin 1 and key 2 are in the appropriate position; the first clamp 4 and the second clamp 5 are connected and tightened by bolts to achieve the purpose of locking the main rotating shaft 3.

[0051] In summary, the locking mechanism provided by this invention achieves the purpose of locking the main rotating shaft 3 through the connection of the first clamp 4 and the second clamp 5. By adjusting the main rotating shaft 3, the installation angle of the component to be installed can be flexibly adjusted, and the adjustment of the installation angle is very flexible and convenient, requiring only the loosening of the locking bolts of the first clamp 4 and the second clamp 5. By adjusting the extension length of the main rotating shaft 3 and the size of the main support 7, installation requirements in different spaces can be met. This locking mechanism has a simple structure, reliable performance, and is easy to install and adjust, making it an excellent choice for underwater vehicles, small aircraft, and other machinery that require ensuring the installation angle of components, especially for applications requiring precise wing installation angles.
