[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] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0020] Traditional traction and loading mechanisms rely too heavily on manual operation, resulting in high labor costs. Furthermore, traditional mechanical locking mechanisms are prone to accidental disengagement due to vibration and wear, requiring a high level of operator experience, thus causing inconvenience for staff.

[0021] In view of this, the present invention provides a robust traction quick-loading mechanism. Through the cooperation of a handle, handle frame, main frame, angle limiting rod, first connecting rod fixed axis, second connecting rod fixed axis, hydraulic cylinder, traction hook and auxiliary parts, the loading work can be completed quickly. Due to its self-driving nature, it is more convenient for workers to use. Moreover, after loading is completed, it can self-lock to prevent the hook from coming off, thereby improving the robustness of the robust traction quick-loading mechanism and making it more convenient for workers to use.

[0022] Example 1: By Figure 1 , 2 As can be seen from points 3 and 4, a robust traction quick-loading mechanism includes a handle 1, a handle frame 2 is provided below the handle 1, a first connecting rod fixed shaft 5 is rotatably connected to the lower part of the handle frame 2, a main frame 3 is fixedly connected to the outer wall of the first connecting rod fixed shaft 5, a second connecting rod fixed shaft 6 is fixedly connected to the lower part of the main frame 3, a traction hook 7 is rotatably connected to the outer wall of the second connecting rod fixed shaft 6, a connecting rod 13 is provided on one side of the traction hook 7, the connecting rod 13 is rotatably connected to the lower part of the main frame 3, an angle limiting rod 4 is fixedly connected to the inner wall of the main frame 3, and the outer wall of the angle limiting rod 4 is in contact with the inner wall of the handle frame 2;

[0023] In the specific implementation process, it is worth noting that the angle limiting rod 4 is assembled in the groove of the handle frame 2 to limit the opening and closing angle of the final traction hook 7. When the handle 1 is pulled manually, the handle frame 2 rotates around the fixed axis 5 of the first connecting rod. The connecting rod 13 is composed of two connecting rods, and the two connecting rods are rotatably connected by a pin.

[0024] Furthermore, the bottom of the main frame 3 is fixedly connected with an auxiliary component 8;

[0025] In the specific implementation process, it is worth noting that the auxiliary component 8 can work with the traction hook 7 to form a closed clamping space, thereby preventing the hook from coming off.

[0026] Furthermore, a housing 9 is fixedly connected to the top of the handle frame 2, the lower outer wall of the handle 1 is inserted into the inner wall of the housing 9, and a spring 10 is fixedly connected to the inner wall of the housing 9, with the bottom of the spring 10 fixedly connected to the lower outer wall of the handle 1.

[0027] In the specific implementation process, it is worth noting that when traction is performed, the elastic potential energy of spring 10 can be used to buffer the instantaneous impact during traction, thereby preventing the robust traction quick-loading mechanism from being damaged due to the instantaneous impact.

[0028] Furthermore, a locking block is fixedly connected to the bottom of handle 1, and a damping pad is fixedly connected to the lower outer wall of handle 1.

[0029] In the specific implementation process, it is worth noting that the locking block can limit the handle 1 and the housing 9, and the damping pad can increase the friction between the handle 1 and the housing 9, thereby consuming the elastic potential energy of the spring 10 when it deforms, so that the spring 10 can stabilize quickly. In addition, the staff should replace the spring 10 and the damping pad regularly according to the actual use, so as to avoid long-term use and affecting its operation requirements.

[0030] Furthermore, a hydraulic fixing rod 12 is rotatably connected to the inner wall of the main frame 3, and a hydraulic rod 11 is fixedly connected to the outer wall of the hydraulic fixing rod 12. The end of the hydraulic rod 11 is rotatably connected to the lower inner wall of the handle frame 2 through a pin.

[0031] In the specific implementation process, it is worth noting that the model of the hydraulic rod 11 is not limited, as long as it meets the usage requirements. The hydraulic rod 11 can change the angle of the traction hook 7, and thus the traction hook 7 can be used to load and clamp items.

[0032] Specifically, when using this robust traction quick-locking mechanism, when the traction hook 7 is closed, the hydraulic rod 11 exerts a thrust on the handle frame 2. This thrust creates a torque with the first connecting rod fixed axis 5. The contact pressure between the angle limiting rod 4 and the angle limiting groove creates a counter-torque with the first connecting rod fixed axis 5, thus maintaining the mechanism in its current state. Manually overcoming the hydraulic thrust, the handle 1 is pulled, causing the handle frame 2 to rotate around the first connecting rod fixed axis 5. The handle frame 2 then moves the connecting rod 13, changing the angle of the connecting rod 13. The connecting rod 13 then rotates the second connecting rod fixed axis 6, causing the traction hook 7 to rotate around the second connecting rod fixed axis 6. Rotation completes the purpose of opening the traction hook 7. When the traction hook 7 is open, the hydraulic rod 11 exerts a thrust on the handle frame 2. This thrust forms a torque with the first connecting rod fixed axis 5. The contact pressure between the angle limiting rod 4 and the angle limiting groove forms a counter-torque with the first connecting rod fixed axis 5, thereby maintaining the mechanism in its current state. When the traction hook 7 is closed, the traction hook 7 forms a self-locking angle with the connecting rod 13. The force on the traction hook 7 is a tangential force rotating around the second connecting rod fixed axis 6. Due to the existence of the self-locking angle, this tangential force cannot change the closed state of the traction hook 7. This self-locking angle can only be broken by applying force from the handle 1 end.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
