[0025] The technical solutions in the embodiments will be described clearly and completely below with reference to the drawings, and the described embodiments are only a part of the embodiments, and all other embodiments obtained by those skilled in the art without creative work on the basis of the embodiments in the present application shall fall within the protection scope of the present application.
[0026] As shown in Figures 1 to 4 , the present embodiment designs a hinge assembly with a locking hook, which comprises a fixed part 1 and a rotating part 2 and the like.

[0028] The locking arm 5 is rotatably connected to the fixed part 1, the rotating part 2 is rotatably connected to the limiting connecting rod 3, and the locking arm 5 and the limiting connecting rod 3 are rotatably connected to each other; when the rotating part 2 rotates relative to the fixed part 1, the locking arm 5 and the limiting connecting rod 3 can be linked, the locking arm 5 can rotate relative to the fixed part 1 within the range of 0 to 90°±5°, and the limiting connecting rod 3 can rotate relative to the limiting connecting rod 3 within the range of 0 to 90°±5°.
[0029] The locking hook 4 is rotatably arranged on the locking arm 5, and the first locking part 21 and the second locking part 22 are arranged on the rotating part 2.
[0030] When the rotating member 2 rotates to the first position, the locking arm 5 and the limiting link 3 are both in a horizontal state, that is Figure 3 When the rotating member 2 rotates to the second position, the locking arm 5 and the limiting link 3 are both in a vertical state, which is not shown in the figure, the connecting point of the locking arm 5 and the limiting link 3 is located on the left side of the connecting line between the connecting point of the limiting link 3 and the rotating member 2 and the connecting point of the locking arm 5 and the fixed member 2 (that is, the connecting point of the locking arm 5 and the limiting link 3 is located on the side close to the fixed member 1), so as to prevent the limiting link 3 from rotating to the right (that is, to prevent the limiting link 3 from rotating away from the fixed member 1) by using the elastic force of the limiting link 3 itself, so as to achieve the limiting state when the rotating member 2 rotates to the first position, and then the locking hook 4 hooks the second locking part 22, at this time, the rotating member 2 and the fixed member 1 can be locked to be perpendicular to each other. When the locking hook 4 is pressed, the locking hook 4 can be unhooked from the second locking part 22.
[0031] When the rotating member 2 rotates to the second position, the locking arm 5 and the limiting link 3 are both in a vertical state, which is not shown in the figure, the connecting point of the locking arm 5 and the limiting link 3 is located on the left side of the connecting line between the connecting point of the limiting link 3 and the rotating member 2 and the connecting point of the locking arm 5 and the fixed member 2 (that is, the connecting point of the locking arm 5 and the limiting link 3 is located on the side close to the fixed member 1), so as to prevent the limiting link 3 from rotating to the right (that is, to prevent the limiting link 3 from rotating away from the fixed member 1) by using the elastic force of the limiting link 3 itself, so as to achieve the limiting state when the rotating member 2 rotates to the first position, and then the locking hook 4 hooks the second locking part 22, at this time, the rotating member 2 and the fixed member 1 can be locked to be perpendicular to each other. When the locking hook 4 is pressed, the locking hook 4 can be unhooked from the second locking part 22.
[0032] The locking hook 4 is rotatably connected to the front end of the locking arm 5, that is, the locking hook 4 is located at the operating end of the locking arm 5, so as to facilitate the simultaneous operation of the locking arm 5 and the locking hook 4, and is conducive to the one-handed operation of the two. The front end of the locking arm 5 is provided with a mounting hole; the locking hook 4 is arranged in the mounting hole. The middle part of the locking hook is rotatably connected to the locking arm, and the handle end of the locking hook covers the hole of the mounting hole and slightly protrudes from the mounting hole, so as to improve the anti-mis-touch property of the locking hook 4. The handle end of the locking hook is provided with an anti-slip pattern; the handle end of the locking hook extends to the operating end of the locking arm. The locking hook 4 is in the shape of a U, and hooks are arranged at both ends of the locking part, so as to extend the connecting part of the limiting support and the locking arm 5 into the U-shaped opening of the locking hook 4, so as to realize the space avoidance between the locking hook 4 and the limiting link 3, thereby avoiding the bumping and interference of the two when they rotate relative to each other.
[0033] The connecting shaft of the lock hook 4 and the lock arm 5 is provided with a torsion spring, the hook end of the lock hook has a first inclined surface, the first and second locking parts have a second inclined surface; the first inclined surface cooperates with the second inclined surface to make the lock hook rotate and compress the torsion spring. The torsion of the torsion spring can facilitate the automatic reset of the lock hook 4, and is beneficial to the automatic locking of the lock hook 4 and the first or second locking part 21 or 22 without external force. After the external force overcomes the elastic force of the torsion spring, the lock hook 4 rotates and unhooked from the first or second locking part 21 or 22.
[0034] The rotating member 2 is in the form of a sleeve; an expansion joint is arranged at the front end of the rotating member 2, and screw holes are arranged at both sides of the expansion joint to facilitate the tightening of the expansion joint by a screw, thereby clamping the propeller mounting arm inserted into the rotating member 2.
[0035] The first locking part 21 is arranged at the front end of the rotating member 2, and the second locking part 22 is arranged at the rear end of the rotating member 2; the first locking part 21 is a reverse U-shaped ear or a pipe flange at the front end of the rotating member 2, and the second locking part 22 is a reverse U-shaped ear or a pipe flange at the rear end of the rotating member 2. The first and second locking parts 21 and 22 can cooperate with the outer side of the hook head of the lock hook 4 through inclined surfaces, so that when the lock arm 5 is pushed, the lock hook 4 can rotate under the action of the inclined surface, thereby making the lock hook 4 automatically hook the first or second locking part 21 or 22.
[0036] The rotating member 2 is rotatably connected to the accommodating groove 12 at the front end of the fixed member 1 and can rotate downward; a first side ear 11 is arranged above the front end of the fixed member 1, and the first side ear 11 is rotatably connected to the rear end of the lock arm 5; a second side ear 23 is arranged on the outer side wall of the rotating member 2, and the second side ear 23 is rotatably connected to the limiting link 3 of the lock arm 5.
[0037] The lock arm 5 is in the form of a groove; when the rotating member 2 rotates to the second position, the limiting link 3 rotates to the extension line at the front end of the lock arm 5; when the rotating member 2 rotates to the first position (i.e. Figure 3 the position shown in the figure), the limiting link 3 rotates into the groove cavity of the lock arm 5.
[0038] When the rotating member 2 rotates to the second position, the rotating member 2 is perpendicular to the fixed member 1; when the rotating member 2 rotates to the first position, the rotating member 2 is parallel to the fixed member 1.
[0039] The above examples are only for the purpose of clearly illustrating the examples made, and are not limited to the embodiments; all the embodiments do not need to be exhausted here. The obvious changes or changes derived therefrom are still within the protection scope of the technology.
