Technical Field
[0001] This utility model belongs to the technical field of drone peripheral accessories, specifically relating to a hook with long-distance remote control release and quick manual operation functions. Background Technology
[0002] A drone is an unmanned aircraft that typically consists of an airframe, a power system, a flight control system, a remote control system, and a mission payload system. The airframe is often made of lightweight, high-strength materials, providing a mounting platform and protection for the various components.
[0003] The remote-controlled unhooking capability of drones is necessary to quickly and safely release payloads, such as aerial photography equipment and sensors, during mission execution, thereby improving mission efficiency and flexibility while reducing damage to the drone itself and its payload.
[0004] However, when the existing hooks are used to lift goods, the weight of the goods is directly pressed on the push rod. When the load is heavy, the hook cannot be released and the goods cannot be separated normally. The release buckle is directly subjected to the pressure of the load. The structure is complicated and bulky, and it cannot be released when the load is heavy, making it inconvenient to use. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a hook with long-distance remote control unhooking and quick manual operation functions.
[0006] The technical solution adopted to solve the above technical problems is: a hook with long-distance remote control unhooking and quick manual operation functions, including a hook body, a lifting opening is provided on the lower side wall of the hook body, and a flip hook is rotatably connected to the front wall of the hook body through a flip hook sheath shaft. The flip hook sheath shaft is located below the lifting opening and is fixedly connected to the upper front wall of the hook body with a positioning shaft. An inclined push rod motor is rotatably connected to the side wall of the positioning shaft. The movable end of the push rod motor faces obliquely downward, and the movable end of the push rod motor is provided with a locking and releasing mechanism for locking and releasing the flip hook. The locking and releasing mechanism includes a push rod rocker arm, a control buckle, a control buckle sheath shaft, a limiting protrusion, a fixing rod, and a return spring.
[0007] Furthermore, the top sidewall of the push rod rocker arm is rotatably connected to the movable end sidewall of the push rod motor, and the bottom front wall of the push rod rocker arm is rotatably connected to the middle section of the front wall of the control buckle through the control buckle sheath shaft. The control buckle sheath shaft is fixed to the front wall of the hook body, and the limiting protrusion is integrally formed with the control buckle. The top of the limiting protrusion fits against the oblique lower part of the movable end of the push rod motor.
[0008] Through the above technical solution, the push rod motor drives the push rod rocker arm to swing, amplifying the stroke through the lever principle to ensure that the flipping hook is fully unlocked. The limit protrusion restricts the movement trajectory of the control buckle, preventing it from exceeding the safe stroke and extending the equipment's lifespan. Simultaneously, the hook can be manually triggered to release in case of power failure or emergency, ensuring emergency response capabilities.
[0009] Furthermore, the control buckle is provided with an inner hook groove on the inner side of one end of the lifting opening, and the top of the flipping hook is provided with an outer hook groove on the side wall near the inner hook groove. The inner hook groove and the outer hook groove engage and cooperate.
[0010] Through the above technical solution, the inner hook groove of the control buckle and the outer hook groove of the flipping hook are precisely engaged to form a physical interlock, effectively preventing accidental opening due to vibration or impact.
[0011] Furthermore, the front wall of the control buckle away from the lifting opening has a hanging hole, the fixing rod is located above the push rod rocker arm and fixed to the front wall of the hook body, and the two ends of the return spring are fixedly connected to the fixing rod and the hanging hole respectively.
[0012] Through the above technical solution, the reset spring continuously applies tension, keeping the control latch in a locked state, which is only released during active operation to prevent accidental loosening.
[0013] Furthermore, a lifting ring is fixedly connected to the top of the hook body, and a movable groove is provided on the front wall of the hook body, with the push rod motor located in the movable groove.
[0014] Through the above technical solution, the lifting ring and hook are welded together as a whole, resulting in strong load-bearing capacity, and the movable groove provides space for the push rod motor to move.
[0015] Furthermore, a remote control module is installed inside the push rod motor, and the remote control module is connected to an external remote control signal.
[0016] The above technical solution can receive external signals to achieve remote control, and is suitable for high-altitude operations, hazardous environments or automated processes, reducing the risk of human intervention.
[0017] Furthermore, the bottom opening of the control buckle is larger than the top opening of the flip hook.
[0018] The above technical solution ensures that when the flipping hook is released, the control buckle can push the flipping hook to rotate towards the lifting port, thereby completing the unhooking.
[0019] The beneficial effects of this utility model are as follows: (1) By setting the push rod motor and locking release mechanism, when it is necessary to open the hook, the push rod motor is extended by the remote control to open the reset spring and release the control buckle, and the locking release mechanism is opened to complete the unhooking action. When it is necessary to reset, the push rod motor is retracted by the remote control. At this time, the locking release mechanism can be manually flipped to reset. The structure is ingenious and simple, realizing fast and accurate unhooking action and reliable automatic reset, improving the safety and reliability of UAV operation, and realizing reliable fast loading and unhooking under heavy load. (2) By setting the flip hook sheath shaft and the limit protrusion, in an emergency, the control buckle can also be manually turned counterclockwise, the limit protrusion will be released from the electric push rod, and the locking release mechanism can be opened quickly to ensure emergency response capability.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0023] like Figures 1-4As shown, a hook with remote control release and quick manual operation functions in this embodiment includes a hook body 1. The lower side wall of the hook body 1 is provided with a lifting opening 102. The front wall of the hook body 1 is rotatably connected to a flip hook 6 via a flip hook sheath shaft 5. The flip hook sheath shaft 5 is located below the lifting opening 102 and is fixedly connected to the upper front wall of the hook body 1 with a positioning shaft 2. The side wall of the positioning shaft 2 is rotatably connected to an inclined push rod motor 3. The movable end of the push rod motor 3 faces obliquely downward. The movable end of the push rod motor 3 is provided with a locking and releasing mechanism 4 for locking and releasing the flip hook 6. The locking and releasing mechanism 4 includes a push rod rocker arm 401, a control buckle 402, a control buckle sheath shaft 403, a limit protrusion 404, a fixing rod 405, and a return spring 406; The top sidewall of the push rod rocker arm 401 is rotatably connected to the movable end sidewall of the push rod motor 3. The bottom front wall of the push rod rocker arm 401 is rotatably connected to the middle section of the front wall of the control buckle 402 via the control buckle sheath shaft 403. The control buckle sheath shaft 403 is fixed to the front wall of the hook body 1. The limiting protrusion 404 is integrally formed with the control buckle 402. The top of the limiting protrusion 404 fits against the lower part of the movable end of the push rod motor 3. The push rod motor 3 is tilted, and the movable end drives the push rod rocker arm 401 to swing. The action stroke is amplified by the lever principle to ensure that the flip hook 6 is fully unlocked. The limiting protrusion 404 limits the movement trajectory of the control buckle 402 to prevent it from exceeding the safe stroke and extend the equipment life. At the same time, the hook can be manually triggered to release in case of power failure or emergency, ensuring emergency response capability. The linkage structure between the push rod rocker arm 401 and the control buckle 402 is ergonomic and can be unlocked by pressing with one hand. The control buckle 402 is located on the inner side of one end of the opening of the lifting port 102 and has an inner hook groove 4021. The top of the flip hook 6 is located on the side wall of one end near the inner hook groove 4021 and has an outer hook groove 601. The inner hook groove 4021 and the outer hook groove 601 engage and cooperate. The inner hook groove 4021 of the control buckle and the outer hook groove 601 of the flip hook 6 are precisely engaged to form a physical interlock, which effectively prevents accidental opening due to vibration or impact. The front wall of the control buckle 402 away from the opening of the lifting port 102 has a hanging hole 4022. The fixing rod 405 is located above the push rod rocker arm 401 and is fixed to the front wall of the hook body 1. The two ends of the return spring 406 are fixedly connected to the fixing rod 405 and the hanging hole 4022 respectively. The return spring 406 continuously applies tension, so that the control buckle 402 is always in a locked state and is only released during active operation to avoid accidental loosening. The return spring 406 forces the control buckle to return to the initial position after each operation to prevent incomplete locking due to negligence. A lifting ring 7 is fixedly connected to the top of the hook body 1. A movable groove 101 is opened on the front wall of the hook body 1. The push rod motor 3 is located in the movable groove 101. The lifting ring 7 is integrally welded to the hook body 1, which has a strong load-bearing capacity. The movable groove 101 provides a space for the push rod motor 3 to move. The push rod motor 3 is equipped with a remote control module. The remote control module is connected to the external remote control signal and can receive external signals to realize remote control. It is suitable for high-altitude operations, hazardous environments or automated processes, reducing the risk of manual intervention. When it is necessary to release a heavy object, simply remotely control the push rod motor 3 to drive the push rod rocker arm 401 to rotate counterclockwise. At the same time, the movable end of the push rod motor 3 drives the control buckle 402 to rotate by pushing the limit protrusion 404. The outer hook groove 601 disengages from the inner hook groove 4021, which releases the flip hook 6 and releases the heavy object. The bottom opening of the control buckle 402 is larger than the top opening of the flip hook 6, ensuring that when the flip hook 6 is released, the control buckle 402 can push the flip hook 6 to rotate toward the lifting port 102, thereby completing the unhooking.
[0024] The working principle of this embodiment is as follows: When using it, the remote control sends a signal when remotely unhooking, the push rod motor 3 receives the signal and extends the movable rod. While stretching the return spring 406, it drives the push rod rocker arm 401 to rotate counterclockwise. The movable end of the push rod motor 3 drives the control buckle 402 to rotate by pushing the limit protrusion 404. The outer hook groove 601 disengages from the inner hook groove 4021, which releases the flip hook 6 and releases the heavy object, so that the hoisted goods are quickly separated from the drone, and reliable and fast unhooking can still be achieved under heavy load. When hoisting, the material is hung on the hoisting port 102. The center of gravity of the hook is vertical, and the automatic push of the flip hook 6 rotates counterclockwise. The remote control sends a signal, the push rod motor 3 receives the signal and retracts the movable rod, the return spring 406 rebounds, the control buckle 402 resets, and the inner hook groove 4021 of the control buckle 402 hooks the outer hook groove 601 of the flip hook 6 to complete the locking. When manually releasing the hook, with the push rod motor 3 in the retracted state, manually push the handle of the control buckle 402 upward. At this time, the limit protrusion 404 will not be constrained by the push rod motor 3. The control buckle 402 rotates counterclockwise to stretch the reset spring 406. The flip hook 6 loses its constraint and rotates clockwise to release the heavy object. The hook can be manually triggered to release the hook in case of power failure or emergency, ensuring emergency response capability.
[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
