[0027] Referring toFigure 1 , Figure 2 and Figure 3 As shown, a novel self-locking anti-unwinding multi-functional tensioner includes a device frame 1 and a central shaft 2. The central shaft 2 is installed in the middle of the device frame 1 and is rotatably connected to the device frame 1. A take-up wheel 3 is fixedly mounted on the central shaft 2. A ratchet disc 4 is mounted on the outer side of the device frame 1 and is engaged and fixed to the device frame 1. An operating handle 5 is provided on the outer side of the ratchet disc 4. A cooperating gear 6 is installed in the middle of the operating handle 5 and is mounted and fixed on the central shaft 2. The operating handle 5 is provided with a reversing hook 7 corresponding to the cooperating gear 6. A pawl 8 that cooperates with the ratchet disc 4 is also rotatably mounted on the outer side of the device frame 1. A cooperating torsion spring is provided between the device frame 1 and the pawl 8. A locking component 9 for locking the pawl 8 is also installed in the device frame 1. A suspension rope 11 is provided in the middle of the equipment frame 1. One end of the suspension rope 11 is wound on the winding wheel 3, and the other end of the suspension rope 11 is fixedly connected to the equipment frame 1. A suspension hook 12 is also sleeved on the suspension rope 11. By rotating and installing the central shaft 2 in the middle of the equipment frame 1, the winding wheel 3 can be installed through the central shaft 2 during use, ensuring that the suspension rope 11 can be stably wound onto the winding wheel 3. In this way, the winding wheel 3 can be rotated through the central shaft 2 during use. At the same time, after the ratchet disc 4 is engaged with the central shaft 2, it can be locked by the pawl 8, ensuring that the central shaft 2 can only rotate in the forward direction. This facilitates better upward winding operation during operation. When it is necessary to release the suspension rope 11, the pawl 8 can be moved to release the lock on the ratchet disc 4. After the pawl 8 is moved, the locking component 9 can quickly engage and fix it, eliminating the need for the operator to constantly move the pawl 8, making it easier to release the suspension rope 11. The operation handle 5 and the cooperating gear 6 are designed to ensure better rotation of the central shaft 2. In addition, different rotation directions can be selected by using the reversing hook 7.

[0028] Reference Figure 3 and Figure 4 As shown, the central shaft 2 includes a main shaft 21, a side shaft portion 22, and a polygonal rod 23. The side shaft portion 22 is installed at both ends of the main shaft 21, and the polygonal rod 23 is located at the outer end of the side shaft portion 22. The main shaft 21, the side shaft portion 22, and the polygonal rod 23 are integrally formed. A polygonal groove that mates with the polygonal rod 23 is provided at the center of the ratchet disc 4 and the mating gear 6. By designing the central shaft 2 with the main shaft 21, the side shaft portion 22, and the polygonal rod 23 mating together, the winding wheel 3 can be stably installed through the main shaft 21 during use, while the side shaft portions 22 at both ends ensure rotatable installation on the equipment frame 1. At the same time, the polygonal rod 23 ensures that the ratchet disc 4 and the mating gear 6 can be stably engaged without loosening.

[0029] Referring to Figure 1 and Figure 5 As shown, the locking assembly 9 comprises a clamping frame rod 91, a supporting spring 92 and an adjusting bracket 93, the clamping frame rod 91 is slidingly installed on the equipment frame 1, the adjusting bracket 93 is fixedly installed on the inner side of the equipment frame 1, and the supporting spring 92 is fixedly installed between the clamping frame rod 91 and the adjusting bracket 93. By designing the locking assembly 9 as a structure in which the clamping frame rod 91, the supporting spring 92 and the adjusting bracket 93 cooperate, the supporting spring 92 can be stably installed through the adjusting bracket 93 when in use, so that the clamping frame rod 91 slidingly installed on the equipment frame 1 can be supported by the supporting spring 92 during use, and the clamping frame rod 91 can automatically pop out after the pawl 8 is actuated by the operator. The clamping frame rod 91 comprises a sliding rod 911, a clamping disc 912 and a first disc shell 913, the sliding rod 911 is slidingly installed on the equipment frame 1, and the limiting plug rod 910 is inserted and connected to the sliding rod 911, and the clamping disc 912 and the first disc shell 913 are fixedly installed at both ends of the sliding rod 911. By designing the clamping frame rod 91 as a structure in which the sliding rod 911, the clamping disc 912 and the first disc shell 913 cooperate, the sliding rod 911 can be connected to the supporting spring 92 through the first disc shell 913 when in use, and the clamping disc 912 is provided to ensure that it is supported on the side of the pawl 8 after being extended, thereby achieving clamping and locking of the pawl 8. The adjusting bracket 93 comprises a threaded tube 931, a threaded rod 932 and a second disc shell 933, the threaded tube 931 is fixedly installed on the inner side of the equipment frame 1, the threaded rod 932 is threadedly connected to one end of the threaded tube 931, and the second disc shell 933 is fixedly installed at the other end of the threaded rod 932. By designing the adjusting bracket 93 as a structure in which the threaded tube 931, the threaded rod 932 and the second disc shell 933 cooperate, the threaded rod 932 can be installed through the threaded tube 931 when in use, and the second disc shell 933 on the threaded rod 932 is connected to the supporting spring 92, so that when the supporting spring 92 loses elasticity after long-term use, the threaded rod 932 can be rotated to increase the size of the threaded rod 932 extending from the threaded tube 931, thereby compressing the supporting spring 92 and ensuring better supporting elasticity of the supporting spring 92.

[0030] In the embodiment, during actual installation, the winding wheel 3 is sleeved and fixed on the main shaft rod 21, then the side shaft part 22 at both ends of the main shaft rod 21 is rotatably installed on the equipment frame 1, then the ratchet wheel 4 is sleeved on the polygonal rod 23, and then the matching gear 6 of the operation handle 5 is sleeved and fixed on the polygonal rod 23, and the use can be performed, so that the normal use can be realized. During use, the operator can drive the central shaft 2 to rotate by reciprocating the operation handle 5, and then the central shaft 2 drives the winding wheel 3 to wind the suspension rope 11. When the suspension rope 11 needs to be loosened, the pawl 8 is actuated to release the action on the ratchet wheel 4, and the clamping frame rod 91 can be pushed out under the action of the supporting spring 92, so that the clamping disc 912 is just clamped and locked to the pawl 8. In this way, the ratchet wheel 4 can rotate freely, and the suspension rope 11 can be easily loosened.

[0031] The above is the preferred embodiment of the utility model, and the person skilled in the art of the utility model can change and modify the above embodiment. Therefore, the utility model is not limited to the above specific embodiments, and any obvious improvement, replacement or modification made by the person skilled in the art on the basis of the utility model belongs to the protection scope of the utility model.
