The movable spring piece 72 is composed of a thin copper sheet and a rubber end. The annular disc 1 has a locking groove, which is located on the vertical line of the meshing point of the outer teeth of the backstop gear 4. The rubber end is locked to the annular disc 1 through the locking groove to limit the movable spring piece 72.

[0014] Preferably, the inner tooth ring 204 has internal teeth on its inner side, and the meshing teeth 205 mesh with the internal teeth. When the trapezoidal shaft 202 is rotated, the meshing teeth 205 swing back and forth and intermittently mesh with the internal teeth 204 to achieve anti-return self-locking.

[0015] The second aspect of the present invention provides a method of using the above-mentioned deformable hook.

[0016] Specifically, the steps include the following:

[0017] S1. The operating rod 9 is threadedly connected to the rotating shaft 2, and the movable spring piece 72 is inserted into the snap-fit ​​groove to complete the anti-reverse gear 4.

[0018] S2. Rotate the long operating lever 9, which drives the take-up wheel 3 to rotate through the rotating shaft 2, thereby winding up the flexible strip 5 until the splicing block 6 is perpendicular to the long operating lever 9. In the check state, the end of the flexible strip 5 that enters the winding take-up wheel 3 is L1; the end that exits the take-up wheel 3 is L2. When L1 equals L2, the tension on both sides of the flexible strip 5 is equal, which is considered the initial state, L1 = L2 = L / 2.

[0019] S3. Push the operating rod 9 until the two front blocks of the splicing block 6 pass through the fixing ring 11. Then rotate the operating rod 9. Due to the obstruction of the fixing ring 11, L1 is tightened and L2 is extended. After rotating W turns, the frontmost splicing block 6 is in contact with the side of the annular disc 1, which completes the locking. Rotate in the opposite direction to unscrew the operating rod 9 to complete the hanging and fixing operation.

[0020] W=(L / 2-2Q) / R

[0021] Q: Diameter of take-up reel 3; M: Number of splicing blocks 6, M is 6 to 8; L: Length of flexible belt 5; R: Reference base is Q*(0.13 to 0.2)*M, take 0.2 when M is 6, take 0.13 when M is 8;

[0022] S4. When removing the sign, unfold the loosening rod 10 located outside the operating rod 9, push the operating rod 9 so that the loosening rod 10 passes through the movable rope 71, pull the operating rod 9 so that its movable spring piece 72 disengages from the locking groove, the anti-reverse gear 4 loses its anti-reverse function, the flexible belt 5 springs back, so that its splicing block 6 returns to its initial state and is perpendicular to the operating rod 9, and the sign automatically detaches.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] The device provided by the first aspect of the present invention includes an annular disc, a rotating mechanism, a take-up reel, a flexible belt, splicing blocks, and a check mechanism. The check mechanism prevents the rotating mechanism from rotating, ensuring that the take-up reel can only rotate in one direction during rotation. During rotation, the flexible belt is pulled, causing the splicing blocks to retract and thus attaching the sign. When the sign is removed, the check mechanism disengages, the flexible belt rebounds, causing the take-up reel to rotate back, the rotating mechanism returns to its initial position, and the sign automatically falls off. The overall structure is simple and easy to use.

[0025] The second aspect of this invention provides a method for using the aforementioned deformable hook. When hanging a sign, the method allows for preliminary measurement based on the number of rotations of W, facilitating confirmation of the locking state during actual operation and preventing the hook from falling due to lack of locking or excessive rotational force causing breakage of the flexible belt. This method enables users to quickly master the operating techniques and complete the hanging and retrieval of the sign. Attached Figure Description

[0042] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0043] Please see Figures 1-6 14-15, Embodiment 1 of this application provides a deformable hook, including an annular disc 1, an operating rod 9, and a fixed hanging ring 11 (see 14-15). Figure 14 The ring disc 1 has a hanging strap 8 fixedly connected to its bottom. A rotating mechanism is installed on the inner side of the ring disc 1. One end of the operating rod 9 is threaded to the rotating mechanism. A take-up reel 3 is mounted on the rotating mechanism. A flexible strip 5 is wound around the outer side of the take-up reel 3. Multiple splicing blocks 6 are mounted on the flexible strip 5. Each splicing block 6 is a regular hexagon, and each set of opposite facets of the splicing block 6 has a through groove. The flexible strip 5 passes through the through grooves sequentially from the splicing block 6 at the end furthest from the take-up reel 3, and after winding around the take-up reel 3, (as shown in the image). Figure 1 or Figure 7 (As shown), then through another through slot, the splicing block 6 is passed through to the leftmost side and locked on the outside of the through hole. The splicing block 6 closest to the take-up reel 3 is fixed to the outside of the annular disc 1.

[0044] A movable rope 71 is connected to the annular disc 1, and a check mechanism is provided at the end of the movable rope 71 away from the annular disc 1; the rotating mechanism drives the take-up wheel 3 to rotate, shrinks and adjusts the flexible belt 5, and changes the bending angle of the splicing block 6; the check mechanism is used to prevent the rotating mechanism from turning back.

[0045] The rotating mechanism includes a rotating shaft 2 movably connected to the inner side of the annular disc 1, a take-up reel 3 fixed to the outer side of the rotating shaft 2, a threaded rod fixedly connected to the top of the operating rod 9, a threaded groove adapted to the threaded rod being opened on the inner side of the rotating shaft 2, and the operating rod 9 being threadedly connected to the rotating shaft 2. The operating rod 9 drives the rotating shaft 2 to rotate and drives the take-up reel 3 to rotate, thereby adjusting the flexible belt 5.

[0046] The anti-return mechanism includes a movable spring 72 located at the end of the movable rope 71 away from the annular disc 1, and a anti-reverse gear 4 fixedly installed on the rotating shaft 2. The movable spring 72 is composed of a thin copper sheet and a rubber end. The annular disc 1 has a locking groove located on the vertical line of the meshing point of the external teeth of the anti-reverse gear 4. The rubber end is locked to the annular disc 1 through the locking groove to limit the movable spring 72. The thin copper sheet is locked at the tooth groove of the anti-reverse gear 4 to prevent the rotating shaft 2 from turning back.

[0047] A hinge seat is fixedly connected to the outer side of the operating rod 9. A loosening rod 10 is hinged to the inner side of the hinge seat, and the loosening rod 10 can rotate 180 degrees around the central axis of the hinge seat. The inner side of the hinge seat has a locking structure.

[0048] The flexible belt 5 has 6 to 8 splicing blocks 6, and the two adjacent splicing blocks 6 are flexibly connected to each other. The through hole is located at the center of the cut side of the splicing block 6. The annular disc 1 is made of a circular plate and a cuboid plate, and an assembly groove is opened at the center of the circular plate. The rotating shaft 2 is movably locked in the assembly groove. At the splicing point of the circular plate and the cuboid plate, a square locking groove is opened from left to right. The locking groove is used to lock the movable spring 72. The flexible belt 5 uses an elastic material to increase the friction with the take-up reel 3 and automatically adapt to the length change caused by curling, eliminating the need for the rotation power of the take-up reel 3. The splicing block 6 is made of a tough material. During processing, the connection between the splicing blocks is not completely cut off, so that the splicing blocks 6 can be bent but do not detach from each other. The flexible belt 5 is made of one, two or more of the following materials: flexible cotton thread, polypropylene, nylon, polyester and polyethylene. The take-up wheel 3 is a concave wheel body, and the flexible belt 5 is wrapped twice around the outside of the concave wheel body. The bottom of the hanging belt 8 and the transformer are fixedly connected to the fixed hanging rings 11 of different diameters. The side of the movable rope 71 away from the movable spring 72 can be fixedly connected to the hanging belt 8. The annular disc 1, the rotating shaft 2, the take-up wheel 3, the anti-reverse gear 4 and the splicing block 6 are all made of engineering plastic 3D printing, and have low manufacturing cost, high strength and precision, convenient assembly, sturdiness and durability, and light weight, which can be widely used.

[0049] In addition, when it is necessary to hang the high-altitude sign, the operating rod 9 is screwed into the inner side of the rotating shaft 2 and tightened, and the take-up wheel 3 is rotated to ensure that L1 and L2 on its flexible belt 5 are parallel, so that all splicing blocks 6 are perpendicular to the operating rod 9, and the movable spring 72 is locked in the locking groove on the inner side of the annular disc 1 to prevent the reverse gear 4 from turning back, thus facilitating subsequent rotation and tightening. Then, by holding the operating rod 9, the splicing block 6 is aligned with the center position of the fixed hanging ring 11 and passed through it to ensure that it is inside the fixed hanging ring 11.

[0050] Subsequently, by rotating the long operating rod 9, due to the obstruction of the fixed hanging ring 11 and the anti-reverse gear 4, the rotating shaft 2 can rotate the take-up wheel 3, adjust the tension of the flexible belt 5, and deform the splicing block 6 into different curved shapes. Finally, the splicing block 6 contacts the side of the annular disc 1 to complete the fixation and prevent it from falling off. After the fixation is completed, rotating the long operating rod 9 can detach it from the rotating shaft 2, thus not interfering with its use.

[0051] When the sign needs to be removed, loosen the lever 10 and fix it in place. Then hook the movable rope 71 and pull the operating lever 9 to disengage the movable spring 72 from the locking groove. Since the flexible belt 5 needs to spring back due to its tension, it will automatically drive the take-up wheel 3 to rotate and return to its initial state. Thus, the whole thing will fall out of the fixed hanging ring 11, which completes the overall assembly and disassembly task.

[0052] The operating rod 9, along with its deformable hook, is lifted to contact the attachment of the fixed hanging ring 11, such as the moving contact of a disconnecting switch. This effectively prevents the end of the operating rod 9 from shaking. It slides along the attachment until the deformable hook contacts the outer ring of the operating rod 9, reducing operational difficulty and ensuring safe use.

[0053] Please see Figures 1-6 14-15, Embodiment 2 of this application provides a deformable hook. The rotating mechanism includes a trapezoidal shaft 202 movably installed inside the annular disc 1. A threaded rod is fixedly connected to the top of the operating rod 9. A threaded groove is opened on the inner side of the trapezoidal shaft 202 to match the threaded rod at the top of the operating rod 9. The trapezoidal shaft 202 is threadedly connected to the operating rod 9 through the threaded groove. The operating rod 9 drives the trapezoidal shaft 202 to rotate, which drives the take-up wheel 3 to rotate, thereby adjusting the flexible belt 5 and changing the bending angle of the splicing block 6.

[0054] The anti-return mechanism includes an assembly hole located inside the trapezoidal shaft 202, with a meshing tooth 205 installed inside the assembly hole. A magnetic suction plate 206 is provided on the top of the meshing tooth 205. It also includes an inner gear ring 204 fixedly installed at the bottom of the annular disc 1. A linkage spring is installed on the outside of the magnetic suction plate 206. The magnetic suction plate 206 is fixedly connected to the inner wall of the assembly hole through the linkage spring. An adsorption plate is fixedly installed on the inner bottom wall of the assembly hole and is attracted to the magnetic suction plate 206. The meshing tooth 205 is engaged in the tooth groove of the inner gear ring 204 to prevent the trapezoidal shaft 202 from returning.

[0055] The inner tooth ring 204 has internal teeth on its inner side. The meshing teeth 205 mesh with the internal teeth. When the trapezoidal shaft 202 is rotated, the meshing teeth 205 swing back and forth and intermittently mesh with the internal teeth 204 to achieve anti-return self-locking. The splicing block 6 near the take-up reel 3 is fixed to the top of the annular disc 1. The end of the trapezoidal shaft 202 is stepped and is locked inside the internal teeth 204 through the step shape.

[0056] In addition, the hanging operation mode of Embodiment 2 is the same as that in Embodiment 1, except that there is no need to engage the movable spring piece 72. Instead, the engagement teeth 205 and the magnetic suction piece 206 work together to automatically complete the anti-reverse operation. When the rotating operating rod 9 drives the trapezoidal shaft 202 to rotate and the take-up reel 3 rotates, the engagement teeth 205 and the inner teeth 204 mesh, so that it can only be wound up by external force. When it is necessary to remove it, the movable rope 71 is hooked by the loosening rod 10, so that the magnetic suction piece 206 slides and the engagement teeth 205 disengages. Similarly, due to the rebound of the flexible belt 5, the take-up reel 3 can be automatically driven to rotate, unfolding its splicing block 6 and returning it to the initial state, thereby achieving separation and facilitating subsequent use.

[0057] The hook is deformable, unlike the fixed shape of traditional hooks; the flexible connection method of the splicing blocks 6 allows for a variable number of splicing blocks 6, enabling the hook size to be adjusted to adapt to different usage scenarios. The hook can be operated by touching the attached object, unlike traditional hooks which require suspension for operation, effectively avoiding hand tremors.

[0058] Preferably, when it is necessary to hook the horizontal wire on the crossbar, a 90-degree flexible coupling adapter is added inside the trapezoidal shaft 202 or the rotating shaft 2, and connected to the operating rod 9 through the flexible coupling adapter. The operation method is the same as the two embodiments above, which drives the movement of the take-up wheel 3 and the flexible belt 5 to complete the subsequent locking hook task. Thus, the device can realize the hooking task in both the horizontal and vertical directions, thereby significantly increasing its adaptability and improving the overall device's usability. In addition to threaded connection, the connection method between the operating rod 9 and the rotating shaft 2 or the trapezoidal shaft 202 can also be a snap-fit ​​connection. The snap-fit ​​and disengagement can be controlled by the rod connection. Any component that can complete the connection between the two and can be separated at a relatively far position is in line with the connection method.

[0059] A method for using a deformable hook includes the following steps:

[0060] S1. The operating rod 9 is threadedly connected to the rotating shaft 2, and the movable spring piece 72 is inserted into the snap-fit ​​groove to complete the anti-reverse gear 4.

[0061] S2. Rotate the long operating lever 9, which drives the take-up wheel 3 to rotate through the rotating shaft 2, thereby winding up the flexible strip 5 until the splicing block 6 is perpendicular to the long operating lever 9. In the check state, the end of the flexible strip 5 that enters the winding take-up wheel 3 is L1; the end that exits the take-up wheel 3 is L2. When L1 equals L2, the tension on both sides of the flexible strip 5 is equal, which is considered the initial state, L1 = L2 = L / 2.

[0062] S3. Push the operating rod 9 until the two front blocks of the splicing block 6 pass through the fixing ring 11. Then rotate the operating rod 9. Due to the obstruction of the fixing ring 11, L1 is tightened and L2 is extended. After rotating W turns, the frontmost splicing block 6 is in contact with the side of the annular disc 1, which completes the locking. Rotate in the opposite direction to unscrew the operating rod 9 to complete the hanging and fixing operation.

[0063] W=(L / 2-2Q) / R

[0064] Q: Diameter of take-up reel 3; M: Number of splicing blocks 6, M is 6 to 8; L: Length of flexible belt 5; R: Reference base is Q*(0.13 to 0.2)*M, take 0.2 when M is 6, take 0.13 when M is 8;

[0065] Example 1: The diameter of take-up reel 3 is 1.5; the length of flexible belt 5 is 20; the splicing block 6 is 6.

[0066] Substituting into the formula, W = 20 / 2 - 1.5 * 2 / 1.5 * 0.2 * 6 = 3.8, approximately equal to 3 revolutions.

[0067] Example 2: The diameter of take-up reel 3 is 3; the length of flexible belt 5 is 40; the splicing block 6 is 8.

[0068] Substituting into the formula, W = 40 / 2 - 3 * 2 / 3 * 0.13 * 8 = 4.4, approximately equal to 4.5 revolutions.

[0069] S4. When removing the sign, unfold the loosening rod 10 located outside the operating rod 9, push the operating rod 9 so that the loosening rod 10 passes through the movable rope 71, pull the operating rod 9 so that its movable spring piece 72 disengages from the locking groove, the anti-reverse gear 4 loses its anti-reverse function, the flexible belt 5 springs back, so that its splicing block 6 returns to its initial state and is perpendicular to the operating rod 9, and the sign automatically detaches.

[0070] The working principle of the above embodiments is as follows:

[0071] (1) Insert the movable spring 72 into the snap-fit ​​groove of the annular disc 1 to block the anti-reverse gear 4. Rotate the take-up reel 3 to adjust the splicing block 6 to be perpendicular to the operating rod 9. Then, hold the operating rod 9 and adjust the overall height to align with the fixed hanging ring 11. Then rotate the operating rod 9 to make its rotation axis 2 rotate and the anti-reverse gear 4 rotate passively. Due to the blocking of the movable spring 72, the device cannot automatically spring back. The rotation of its take-up reel 3 makes its flexible belt 5 tight inside and loose outside. Adjust it into a hook shape to achieve hooking with the fixed hanging ring 11.

[0072] (2) When it is necessary to remove the display board, the loosening rod 10 is bent and locked, and passed through the movable rope 71. The operating rod 9 is pulled down forcefully to make the movable spring 72 disengage from the locking groove. Due to the self-contraction property of the flexible belt 5, the take-up wheel 3 is driven to rotate, making the flexible belt 5 rotate to the initial state, thereby automatically completing the disengagement operation. The overall structure is simple and easy to use.

[0073] (3) When removing the display board, the loosening rod 10 passes through the movable rope 71 and pulls down the operating rod 9, which in turn drives the magnetic suction piece 206 to move, causing the biting teeth 205 to disengage from the inner teeth 204. After the engagement is disengaged, the flexible belt 5 springs back, completing the removal task. Since there is a linkage spring on the inside, when the loosening rod 10 is removed, it drives the biting teeth 205 to return to their position, making the whole relatively stable and ensuring actual use.

[0074] (4) When working outdoors in the power industry, this hook can quickly pass through the small space of the metal ring to complete the work. Its hook body can change the relative state and is guided by the rod, making it easy to align. It can be fixed without human intervention, effectively reducing end shaking and ensuring actual operation.
