[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] Reference Figure 1 and Figure 2The utility model provides an embodiment: an anti-unhooking device for an electric tensioner, comprising a hook 1, a fixed frame 2 is fixedly connected inside the hook 1, a rotating shaft 3 is rotatably connected inside the fixed frame 2, a hook 4 is rotatably connected to the outer wall of the rotating shaft 3, one side of the hook 4 contacts the inner wall of the hook 1, a pressure block 5 is fixedly connected to the top of the pressure block 5, a buckle 6 is fixedly connected to the top of the pressure block 5, a through hole 7 is opened inside the pressure block 5, a threaded column 8 is fixedly connected to the top of the fixed frame 2, the threaded column 8 is slidably connected inside the through hole 7, a nut 9 is threadedly connected to the outer wall of the threaded column 8, and a connecting component is provided at the top of the hook 1.
[0033] Specifically, when using the cable tensioner, first pull the buckle 6 to apply force to make the pressure block 5 and the hook 4 rotate open, which opens the internal space of the hook 1 and puts the cable into it. Then release the buckle 6, the pressure block 5 will be released and press the hook 4 to reset it to the closed position. In this process, the through hole 7 opened inside the pressure block 5 will be inserted into the outer wall of the threaded column 8 to ensure that the hook 4 can be completely closed. When the hook 4 is closed, one side of it will contact one side inside the hook 1 to ensure that the inside of the hook 1 is closed. Finally, the nut 9 is inserted into the outer wall of the threaded column 8 and tightened above the through hole 7 to fix it, thereby preventing the cable from accidentally falling off.
[0034] Reference Figure 3 and Figure 4 The connecting component includes a supporting chain 10, the bottom of the supporting chain 10 is fixedly connected to the top of the hook 1, the supporting chain 10 is slidably connected with a connecting chain 11 inside, the outer wall of the supporting chain 10 is slidably connected with a first bent plate 12, one side of the first bent plate 12 is fixedly connected with a connecting ring 17, the outer wall of the connecting ring 17 is rotatably connected with a connecting block 18, one side of the connecting block 18 is fixedly connected with a ring 19, the ring 19 is rotatably connected to the outer wall of the buckle 16, and the outer wall of the ring 19 is fixedly connected with a handle 20.
[0035] Specifically, when it is necessary to fix the supporting chain 10 and the connecting chain 11, it is first necessary to pull the handle 20 to apply force, causing the outer wall of the ring 19 connected on one side to start to rotate. The rotation of the ring 19 will transmit force to the connecting block 18 connected to the outer wall, thereby driving the movement of the connecting block 18. The movement of the connecting block 18 will affect the internally connected connecting ring 17, causing it to move. At this time, the movement of the connecting ring 17 will be driven by force to drive the first bent plate 12 to start tightening, thereby achieving a driving effect.
[0036] Reference Figure 3 and Figure 4 The outer wall of the connecting chain 11 is slidably connected to the second bent plate 14, one side of the first bent plate 12 is rotatably connected to a connecting piece 13, one side of the connecting piece 13 is rotatably connected to the outer wall of the second bent plate 14, the first bent plate 12 and the second bent plate 14 are connected through the connecting piece 13, one side of the second bent plate 14 is fixedly connected to a fixing ring 15, and a buckle 16 is rotatably connected inside the fixing ring 15.
[0037] Specifically, at the same time, the ring 19 will also drive the internally connected buckle 16 to rotate, thereby affecting the movement of the fixed ring 15 connected to the outer wall. The movement of the fixed ring 15 will drive the second bent plate 14 to begin to tighten on the outer wall of the support chain 10. At the same time, through the action of the connecting piece 13, the first bent plate 12 will also begin to tighten on the outer wall of the connecting chain 11, thereby fixing the connecting chain 11 and the first bent plate 12 together, effectively preventing them from shaking.
[0038] Working principle: when it is necessary to put the cable into the hook 1, first pull the buckle 6 so that the force drives the pressure block 5 and the hook 4 to rotate and open, and then put the cable into the hook 1, then release the buckle 6, so that the pressure block 5 presses the hook 4 to reset, in this process, the through hole 7 opened in the pressure block 5 will be inserted into the outer wall of the threaded column 8, when the hook 4 is closed, one side of it will contact one side of the hook 1, then the nut 9 is inserted into the outer wall of the threaded column 8 and tightened above the through hole 7 to fix it, thereby achieving the effect of preventing unhooking, when it is necessary to fix the support chain 10 and the connecting chain 11, first pull the handle 20 so that the force drives the outer wall of the ring 19 connected on one side to rotate The force on the connecting block 18 drives the internally connected connecting ring 17 to move, and the connecting ring 17 drives the first bent plate 12 to tighten. At the same time, the ring 19 also drives the internally connected buckle 16 to rotate, and the buckle 16 drives the fixing ring 15 connected to the outer wall to move. The fixing ring 15 drives the second bent plate 14 connected to the outer wall to tighten on the outer wall of the supporting chain 10, and at the same time, the first bent plate 12 is tightened on the outer wall of the connecting chain 11 through the connecting piece 13, so that the connecting chain 11 and the first bent plate 12 are fixed, so as to achieve the effect of connecting and fixing the connecting chain 11 and the first bent plate 12 to prevent shaking.
