Technical Field

[0001] The utility model relates to the technical field of wire tensioners, in particular to a wire tensioner used for fence maintenance. Background Art

[0002] A cable tensioner is a tool used to tighten wiring harness components and is widely used in various fields. For example, in the electrical field, cable tensioners can tighten laid cables to prevent them from sagging. In the agricultural and animal husbandry fields, cable tensioners can re-tighten broken fence wires.

[0003] After searching, the Chinese patent technical document with announcement number CN219801686U discloses a ratchet type tensioner, including a shell, a tensioning shaft rotatably connected inside the shell, a first ratchet fixedly connected to the circumferential surface of the tensioning shaft, a locking shaft rotatably connected inside the shell, a first pawl fixedly connected to the circumferential surface of the locking shaft, a first torsion spring fixedly connected to the circumferential surface of the locking shaft, an end of the first torsion spring away from the locking shaft is fixedly connected to the shell, a tensioning rod rotatably connected to the circumferential surface of the tensioning shaft, and a loosening mechanism is provided inside the tensioning rod.

[0004] In the above technical solution, after the wire harness component to be tightened is connected to the barb, the tightening shaft is driven to rotate by reciprocatingly swinging the tightening rod, so that the steel wire rope connected to the barb can be wound around the tightening shaft, thereby pulling the wire harness component through the barb to tighten the wire harness component. However, in actual use, it is found that the connection between the wire harness component and the barb is mainly fixed by the friction force generated by the contact between the two, which easily leads to looseness between the wire harness component and the barb when the wire harness component is tightened. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a wire tensioner for fence maintenance, which can stably tighten the wire harness components.

[0006] To achieve the above-mentioned objectives, the present utility model provides the following technical solutions: a wire tensioner for fence maintenance, comprising a rack, the rack being provided with a fixed base and a movable base arranged at intervals, the fixed base being fixed to the rack, the movable base being sleeved on the rack and being movable along the direction of the rack, the fixed base and the movable base being respectively provided with a first clamping limit device and a second clamping limit device for clamping the wiring harness component, the movable base being provided with a driving handle, the driving handle being driven to move the movable base toward the fixed base by reciprocating rotation to tighten the clamped wiring harness component.

[0007] The utility model is further configured as follows: a pawl is rotatably connected to the driving handle, and the pawl can engage with the teeth of the rack. A force spring is provided between the movable base and the pawl, and the two ends of the force spring are respectively fixed to the movable base and the pawl, and the force spring is used to tighten the pawl against the teeth of the rack.

[0008] The present utility model is further configured as follows: the first clamping and limiting device includes a first mounting plate, the first mounting plate is fixed to a fixed base, a first limiter is fixed to the first mounting plate, a first connecting rod is rotatably connected to the fixed base, one end of the first connecting rod extends toward the first limiter as a first clamping end, and the other end extends outward as a first handle end, a first pressure spring is provided between the first connecting rod and the fixed base, the two ends of the first pressure spring are respectively fixed to the first connecting rod and the fixed base, and the first pressure spring is used to press the first clamping end toward the first limiter.

[0009] The utility model is further configured as follows: the second clamping and limiting device includes a second mounting plate, the second mounting plate is fixed to the movable base, a second limiter is fixed to the second mounting plate, a second connecting rod is rotatably connected to the movable base, one end of the second connecting rod extends toward the second limiter as a second clamping end, and the other end extends outward as a second handle end, a second pressure spring is provided between the second connecting rod and the movable base, the two ends of the second pressure spring are respectively fixed to the second connecting rod and the movable base, and the second pressure spring is used to press the second clamping end toward the second limiter.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0017] Example 1

[0018] like Figures 1 to 2 As shown, the present embodiment discloses a wire tensioner for fence maintenance, comprising a rack 1, a fixed base 2 and a movable base 3 arranged at intervals on the rack 1, the fixed base 2 is fixed to the rack 1, the movable base 3 is sleeved on the rack 1 and can move along the direction of the rack 1, the fixed base 2 and the movable base 3 are respectively provided with a first clamping limit device and a second clamping limit device for clamping a wiring harness component, a driving handle 4 is provided on the movable base 3, the driving handle 4 drives the movable base 3 to move toward the fixed base 2 by reciprocating rotation, so as to tighten the clamped wiring harness component, when the wiring harness component needs to be tightened, the first clamping limit device and the second clamping limit device can respectively clamp the wiring harness component quickly and stably, thereby preventing the wiring harness component from loosening in the process of moving the movable base 3 toward the fixed base 2 to tighten the wiring harness component, thereby improving the stability of the wiring harness component when tightening;

[0019] The principle of the first clamping and limiting device for quickly and stably clamping the wiring harness component is as follows: the first clamping and limiting device includes a first mounting plate 8171, the first mounting plate 8171 is fixed to the fixed base 2, a first limiter 72 is fixed on the first mounting plate 8171, and a first connecting rod 73 is rotatably connected to the fixed base 2, one end of the first connecting rod 73 extends toward the first limiter 72 as a first clamping end 731, and the other end extends outward as a first handle end 732, a first pressure spring 74 is provided between the first connecting rod 73 and the fixed base 2, and the two ends of the first pressure spring 74 are respectively fixed to the first connecting rod 73 and the fixed base 2, and the first pressure spring 74 is used to press the first clamping end 731 toward the first limiter 72. When clamping the wiring harness component, first rotate the first connecting rod 73, When the first limit stop 72 is in the state of being clamped, the locking nut 731 of the locking nut 73 is unlocked, and the first locking nut 73 is unlocked, so that the first limit stop 72 is unlocked.

[0020] Similarly, the principle of the second clamping and limiting device for quickly and stably clamping the wiring harness component is that the second clamping and limiting device includes a second mounting plate, the second mounting plate is fixed to the movable base 3, the second limiter 82 is fixed to the second mounting plate, and the second connecting rod 83 is rotatably connected to the movable base 3, one end of the second connecting rod 83 extends toward the second limiter 82 as a second clamping end 831, and the other end extends outward as a second handle end 832, and a second pressure spring 84 is provided between the second connecting rod 83 and the movable base 3, and the two ends of the second pressure spring 84 are respectively fixed to the second connecting rod 83 and the movable base 3, and the second pressure spring 84 is used to press the second clamping end 831 toward the second limiter 82. When clamping the wiring harness component, the second connecting rod 83 is first rotated to make the second connecting rod 83 The second clamping end 831 of the connecting rod 83 can be away from the second limiter 82. At this time, the wiring harness component to be clamped can be passed between the second clamping end 831 and the second limiter 82, and then the second connecting rod 83 can be released. At this time, the second pressure spring 84 can drive the second connecting rod 83 to reset, so as to drive the second clamping end 831 to press the wiring harness component toward the second limiter 82. Therefore, the setting of the second pressure spring 84 can increase the positive pressure applied by the second clamping end 831 to the second limiter 82, thereby increasing the friction force generated when contacting the wiring harness component, and thus achieving stable clamping of the wiring harness component. When clamping the wiring harness component, it is only necessary to rotate the second connecting rod 83, thereby improving the convenience of clamping the wiring harness component through the second clamping limit device.

[0021] In this embodiment, the structure for the movable base 3 to move along the rack 1 is that a pawl 5 is rotatably connected to the driving handle 4, and the pawl 5 can engage with the teeth of the rack 1. A force spring 6 is provided between the movable base 3 and the pawl 5, and the two ends of the force spring 6 are respectively fixed to the movable base 3 and the pawl 5. The force spring 6 is used to press the pawl 5 against the teeth of the rack 1. After the first clamping limit device and the second clamping limit device respectively clamp the two sides of the wiring harness component, the driving handle 4 is rotated back and forth to drive the pawl 5 to rotate back and forth, thereby pushing the rack 1 through the pawl 5, which can drive the movable base 3 to move along the direction of the rack 1, so that the movable base 3 can be close to the fixed base 2 to tighten the wiring harness component, and the setting of the force spring 6 can drive the pawl 5 to press against the teeth, thereby avoiding malfunction of the movable base 3.

[0022] Example 2

[0023] like Figure 3As shown, the difference of this embodiment is that the driving handle 4 adopts a telescopic structure. Its specific structure is that a slide groove 41 is provided in the driving handle 4, and an extension rod 43 adapted to the slide groove 41 is provided in the slide groove 41. The extension rod 43 can slide along the slide groove 41. By sliding the extension rod 43 out of the slide groove 41, the length of the driving handle 4 can be increased to increase the force arm, thereby facilitating the reciprocating rotation of the driving handle 4. When not in use, the extension rod 43 can be slid into the slide groove 41 to avoid the entire handle from being pulled out of the drive during transportation or storage. The space occupied by the body becomes larger. In addition, a connecting column 42 is provided on the outside of the driving handle 4. The connecting columns 42 are multiple and are arranged at intervals from each other, and a threaded hole is provided in the connecting column 42. A penetrating connecting hole 431 is provided on the extension rod 43. The connecting hole 431 can be opposite to any threaded hole. Therefore, after the extension rod 43 is slid to a suitable position, the connecting hole 431 is aligned with the corresponding threaded hole, and a locking piece that is threadedly matched with the threaded hole can be screwed in to fix the extension rod 43 to avoid malfunction of the extension rod 43.
