In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0034] Please refer to Figures 1 to 3 A preferred embodiment of the present invention provides a locking flip pulley suitable for a drone, including a pulley bracket 10 and a pulley 20 provided at the bottom of the pulley bracket 10.

[0035] The pulley bracket 10 includes a bottom 11, a hook end 12, and a connecting portion 13 connected to the bottom 11 and the hook end 12, and an opening 14 for cables to enter and exit is formed between the bottom 11 and the hook end 12. An annular structure with an opening 14 is formed between the bottom 11, the hook end 12, and the connecting portion 13, and the opening 14 is arranged at the side of the bottom position. When implemented, the cable can enter and exit from the opening 14 and enter the annular structure, and at this time, the pulley bracket 10 can be suspended on the cable.

[0036] The pulley 20 is installed at the bottom surface of the bottom 11. The pulley 20 can adopt the form of the existing technology, and can be one or more.

[0037] The pulley bracket 10 is provided with a through hole 15 from the top downwards, which penetrates the hook end 12. The through hole 15 is a square hole. A limit plate 16 is provided on the top of the pulley bracket 10. A guide hole 17 is provided on the limit plate 16. The guide hole 17 is a round hole.

[0038] A locking slide plate 30 is slidably disposed in the through hole 15, and the cross-sectional shape of the locking slide plate 30 is consistent with the cross-sectional shape of the through hole 15. An abutment plate 18 is disposed at the bottom of the locking slide plate 30, and the abutment plate 18 is disposed transversely outwardly and perpendicular to the locking slide plate 30. A guide column 19 is disposed upwardly on the abutment plate 18, and the guide column 19 is a cylindrical light column. The extension direction of the guide column 19 is consistent with the extension direction of the locking slide plate 30 and passes through the guide hole 17.

[0039] When the locking slide 30 is pulled upward, the locking slide 30 moves upward relative to the pulley bracket 10, and can drive the abutment plate 18 and the guide column 19 to move upward together. At this time, the locking slide 30, the abutment plate 18 and the guide column 19 are staggered with the opening 14, such as Figure 2 As shown, at this time, the cable can enter from the opening 14; and when the relative upward pulling force is cancelled, under the action of the gravity of the locking slide 30, the abutment plate 18 and the guide column 19, the locking slide 30, the abutment plate 18 and the guide column 19 move downward, and the locking slide 30 can abut on the bottom 11 to lock the opening 14, as shown in FIG. Figure 3 As shown, at this point, the cables cannot enter or exit.

[0040] During implementation, the locked flip pulley is hoisted by the drone 70, and the drone is hoisted at a position connected to the top of the locking slide plate 30. Under the weight of the pulley bracket 10 and / or the weight of some hanging objects, the pulley bracket 10 moves downward, that is, the locking slide plate 30 slides upward relative to the pulley bracket 10, driving the abutment plate 18 and the guide column 19 to move upward together, and the locking slide plate 30, the abutment plate 18 and the guide column 19 are staggered with the opening 14, such as Figure 2 and Figure 4 As shown, the UAV hoists the locking flip pulley near the cable and hangs the locking flip pulley on the cable through the opening 14. At this time, the cable enters the annular structure formed by the bottom 11, the hook end 12 and the connecting part 13; then the UAV slowly moves downward, the locking flip pulley moves downward, the cable is located at the inner side of the concave arc formed by the hook end 12 and the connecting part 13, and the UAV cancels the hoisting of the locking slide 30. Under the action of its own gravity, the abutment plate 18 and the guide column 19 move downward, and the locking slide 30 moves downward together and can abut on the bottom 11 to lock the opening 14, as shown in FIG. Figure 3As shown, at the same time, the abutment plate 18 and the guide column 19 are also located at the position of the opening 14, realizing multiple strong locking. At this time, the cable cannot enter or exit the pulley bracket 10. When the flip pulley needs to be removed from the cable, the top of the locking slide 30 can be connected by a drone and the locking slide 30 can be pulled upward. At this time, the locking slide 30, the abutment plate 18 and the guide column 19 are staggered from the opening 14, and the cable can go out of the opening 14 to remove the flip pulley. Through the above structure and operation, the locked flip pulley can be suspended on the cable or removed from the cable by a drone. The suspension and removal operations are simple and easy, and it has an automatic locking function, and no additional operation is required to lock.

[0041] In a preferred embodiment, an elastic member 110 is sleeved on the guide column 19, and the elastic member 110 is located between the limit plate 16 and the abutment plate 18. The elastic member 110 is a compression spring and has a reset function. When the force pulling the locking slide 30 upward is canceled, the self-gravity of the locking slide 30, the abutment plate 18 and the guide column 19 is removed, and the downward strength of the locking slide 30, the abutment plate 18 and the guide column 19 can be strengthened by the elastic force of the elastic member 110 to achieve safer locking.

[0042] In a preferred embodiment, a locking slide limit block 111 is provided at the end of the bottom 11, and when the locking slide 30 blocks the opening 14, the locking slide limit block 111 is located on the outside of the bottom end of the locking slide 30. By providing the locking slide limit block 111, the bottom end of the locking slide 30 is limited to prevent it from being deflected outward by force, thereby ensuring that the cable cannot push the bottom end of the locking slide 30 to move outward and open the opening 14 in the locked state, thereby ensuring the effectiveness of the locking and avoiding accidents due to locking failure.

[0043] In a preferred embodiment, a locking member 40 is provided on the side of the hook end 12, and the locking member 40 includes an open locking end 41 at one end and a linkage end 42 at the other end. A linkage limit stopper 112 is provided on the connecting portion 13, and the middle portion of the locking member 40 is rotatably connected to the hook end 12, and under the deadweight of the locking member 40, the linkage end 42 has a downward tendency and abuts against the linkage limit stopper 112, at which time the linkage end 42 is horizontally placed between the hook end 12 and the connecting portion 13, and the open locking end 41 is staggered from the opening 14, at which time, as shown in FIG. Figure 1 and Figure 2 After the cable enters the pulley bracket 10 from the opening 14, the cable moves upward relative to the pulley bracket 10 when suspended and drives the linkage end 42 to rotate upward, and the opening locking end 41 rotates to the opening 14 to lock the opening 14, at this time, as Figure 3The linkage end 42 is provided with a limit card slot 43, and the locking slide 30 is provided with a limit card head 113. When the locking slide 30 moves downward and locks the opening 14, and the opening locking end 41 rotates to the opening 14 and locks the opening 14, the limit card head 113 is inserted into the limit card slot 43 downward to limit the rotation of the locking member 40, thereby ensuring the effectiveness of the locking and avoiding accidents caused by the failure of the locking; at the same time, the locking member 40 can also limit the locking slide 30 in the reverse direction through the interaction between the limit card head 113 and the limit card slot 43, thereby fixing the locking slide 30. During implementation, when hoisting, the locking slide 30 is pulled up. At this time, under the deadweight of the locking member 40, the linkage end 42 has a downward tendency and abuts against the linkage limit stopper 112. The linkage end 42 is horizontally placed between the hook end 12 and the connecting portion 13, and at the same time, the opening locking end 41 rotates outward and staggers the opening 14; after the cable enters, the cable moves upward relative to the pulley bracket 10 during suspension, driving the linkage end 42 to rotate upward, and the opening locking end 41 rotates to the opening 14 to lock the opening 14, and at the same time, the locking slide 30 moves downward, and the limit clamp 113 is clamped downward into the limit clamping groove 43 to limit the rotation of the locking member 40. At this time, the locking member 40 cannot rotate and can effectively lock the opening 14 to ensure that the cable cannot accidentally fall out. When the locking slide 30 is pulled upward, the limit clamp 113 moves upward together and disengages from the limit clamping groove 43, and at this time, the restriction on the locking member 40 is released.

[0044] The limiting card slot 43 is provided on the top surface of the linkage end portion 42 . The top surface of the linkage end portion 42 is an inclined surface or an arc surface. In this exemplary embodiment, the top surface of the linkage end portion 42 is an arc surface so that the limiting card head 113 can be smoothly inserted into the limiting card slot 43 .

[0045] There are two locking members 40 , which are respectively disposed on two opposite sides of the pulley bracket 10 , so as to strengthen the locking of the pulley bracket 10 by the locking members 40 .

[0046] In a preferred embodiment, a guide arm 50 is provided at the end of the hook end 12, and the guide arm 50 extends obliquely downward, so that when the locking flip block is suspended on the cable, the guide arm 50 assists the cable to enter the opening 14. Preferably, the guide arm 50 is S-shaped as a whole, and the end is tilted outward and upward.

[0047] In a preferred embodiment, the locking flip pulley suitable for the UAV further includes a connector 60, which is used to connect the UAV and the top of the locking slide 30, that is, the UAV acts on the top of the locking slide 30 through the connector 60. The connector 60 includes a UAV connecting portion 61 that is Y-shaped as a whole. The Y-shaped UAV connecting portion 61 can use a Y-shaped sling. The two ends of the upper end of the UAV connecting portion 61 are respectively connected to the UAV, which can effectively avoid rotation at the upper part and affect the hanging. A three-claw hook 62 is provided on one end of the lower end. A hanging ring 31 is provided on the top of the locking slide 30, and the hanging ring 31 is hung on the two claws 64 of the three-claw hook 62 to facilitate stability. The form of lifting the hanging ring 31 by the three-claw hook 62 is helpful for connecting and disconnecting the locking slide 30 with the connector 60. A hook groove 63 is provided on the hook claw of the three-claw hook 62, so that when the hanging ring 31 is hung on the two hook claws 64 of the three-claw hook 62, the hanging ring 31 is located on the hook groove 63 of the two hook claws 64, which can effectively prevent the pulley from rotating and swinging when turning over during lifting, so as to facilitate hanging in or removing from the cable.

[0048] The present invention provides a locking flip pulley suitable for unmanned aerial vehicles, which is suitable for use with supporting unmanned aerial vehicles. The flip pulley is suspended on a cable (such as a wire) by using the unmanned aerial vehicle, and then the unmanned aerial vehicle is detached from the flip pulley by a remote control device, so that the suspension can be achieved, and the flip pulley can be automatically locked. When disassembling, the unmanned aerial vehicle is flown above the flip pulley, and the unmanned aerial vehicle is operated to connect with the locking slide of the flip pulley, and finally the flip pulley is lifted and removed. This technical solution can greatly improve work efficiency, reduce work intensity, save operators, and improve work safety. It can realize the suspension of the locked flip pulley on the cable or disassembly and removal from the cable by the unmanned aerial vehicle. The suspension and disassembly operations are simple and easy, and it has an automatic locking function, and no additional operation is required to lock it. This solves the problem that the existing flip pulley is not conducive to suspension by unmanned aerial vehicles and the locking form is complicated.

[0049] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
