Description

Technical Field

[0001] This utility model relates to the field of wire tensioning technology, and in particular to a gear tensioning device. Background Technology

[0002] In wire tensioning operations, early methods primarily involved manual tightening. This method was not only labor-intensive but also difficult to maintain uniform and stable tension. When tensioning long distances of wire, manual operation was extremely inefficient. Furthermore, human fatigue during continuous exertion led to significant variations in wire tension after tightening, failing to meet the requirements of engineering scenarios demanding high wire tension, such as power transmission lines. Inconsistent wire tension could affect line stability and increase safety hazards. Later tensioning tools, while simple in design, lacked effective locking and adjustment mechanisms. For example, some basic tensioning clamps could not reliably secure the wire after tightening, making it prone to loosening under external vibrations or slight changes in tension, resulting in poor tightening effects and requiring repeated operations, wasting time and resources.

[0003] Furthermore, in some complex working environments, such as working at heights or tightening wires in confined spaces, existing wire tightening devices are difficult to operate due to their large size and inconvenience. This not only affects the work progress but also poses a certain threat to the safety of operators.

[0004] Therefore, it is necessary to provide a new gear tensioning device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a gear tensioning device.

[0006] The gear tensioning device provided by this utility model includes a U-shaped frame, on which a rotating shaft is mounted and rotatably connected, and on which two symmetrically distributed ratchet wheels are fixedly mounted;

[0007] The U-shaped frame is equipped with a mounting assembly, and the mounting assembly is equipped with a U-shaped locking bar for locking the ratchet;

[0008] Both ends of the U-shaped locking rod are equipped with torsion springs.

[0009] Preferably, the mounting assembly includes a U-shaped plate, with fixing plates fixedly installed at both ends of the U-shaped plate, and mounting cylinders fixedly installed on the fixing plates. The mounting cylinders have side grooves communicating with the cylinder cavity, and the fixing plates have mounting holes.

[0010] Preferably, the outer walls on both sides of the U-shaped frame are provided with insertion slots, and the insertion slots are provided with screw holes.

[0011] Preferably, the two fixing pieces are respectively inserted into two insertion slots opened on the outer wall of the U-shaped frame, and the fixing pieces are fixedly installed on the screw holes by screws passing through the mounting holes.

[0012] Preferably, the two connecting ends of the torsion spring are respectively fixedly installed with side rod A and side rod B, and the torsion spring is inserted into the mounting cylinder. Side rod A is fixedly connected to the rod head of the U-shaped locking rod, and side rod B is inserted into the side groove.

[0013] Preferably, the middle rod of the U-shaped locking rod is fixedly fitted with a sleeve.

[0014] Preferably, the rotating shaft has a through hole.

[0015] Compared with related technologies, the gear tensioning device provided by this utility model has the following advantages:

[0016] This invention involves passing one end of a steel wire through a through hole in a rotating shaft, securing the wire end to the shaft with pliers, then pushing the U-shaped locking rod downwards to disengage it from the ratchet's tooth groove. Rotating the shaft then tightens the loose steel wire. Once the wire is secured, releasing the U-shaped locking rod allows it to engage with the ratchet's tooth groove under the elastic action of a torsion spring. This automatic locking of the ratchet by the torsion spring and U-shaped locking rod reduces manual intervention and improves operational efficiency. The mounting assembly is fixed with screws via insertion slots, and the symmetrical design of the U-shaped plate enhances the overall structural stability and vibration resistance.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] Please see Figures 1 to 5 The present invention provides a gear tensioning device, which includes a U-shaped frame 1, a ratchet 3, a mounting assembly 4, and a torsion spring 6.

[0026] In the embodiments of this utility model, please refer to Figures 1 to 5 A rotating shaft 2 is mounted on the U-shaped frame 1, and a through hole 2a is provided on the rotating shaft 2. Two symmetrically distributed ratchet wheels 3 are fixedly mounted on the rotating shaft 2. A mounting assembly 4 is mounted on the U-shaped frame 1, and a U-shaped locking rod 5 for locking the ratchet wheels 3 is mounted on the mounting assembly 4. Specifically:

[0027] The mounting assembly 4 includes a U-shaped plate 41. Fixing plates 42 are fixedly installed at both ends of the U-shaped plate 41, and mounting cylinders 43 are fixedly installed on the fixing plates 42. The mounting cylinders 43 have side grooves 43a that communicate with the cylinder cavity, and the fixing plates 42 have mounting holes 42a. The outer walls on both sides of the U-shaped frame 1 have insertion grooves 1a, and the insertion grooves 1a have screw holes 1b. The two fixing plates 42 are respectively inserted into the two insertion grooves 1a on the outer wall of the U-shaped frame 1, and the fixing plates 42 are fixedly installed on the screw holes 1b by screws passing through the mounting holes 42a.

[0028] Both ends of the U-shaped locking rod 5 are equipped with torsion springs 6, and the two connecting ends of the torsion springs 6 are respectively fixedly installed with side rod 61 A and side rod 61 B. The torsion springs 6 are inserted into the mounting cylinder 43. Side rod 61 A is fixedly connected to the rod head of the U-shaped locking rod 5, and side rod 61 B is inserted into the side groove 43a.

[0029] It should be noted that: the torsion springs 6 at both ends of the U-shaped locking rod 5 are inserted into the mounting cylinder 43, and the B-side rod 61 is embedded into the side groove 43a to complete the assembly of the torsion springs 6. When installing the mounting bracket assembly 4, the fixing plates 42 on both sides of the U-shaped plate 41 are inserted into the insertion grooves 1a opened on the outer wall of the U-shaped frame 1. Then, the fixing plates 42 are fixed into the screw holes 1b with screws to complete the installation of the U-shaped locking rod 5 on the U-shaped frame 1.

[0030] When tightening the steel wire, one end of the steel wire is passed through the through hole 2a of the rotating shaft 2. The through end of the steel wire is then secured to the rotating shaft 2 with pliers. Then, the U-shaped locking rod 5 is pushed down to make it slip out of the tooth groove of the ratchet 3. The rotating shaft 2 is then rotated to tighten the loose steel wire. After the steel wire is tightened, the U-shaped locking rod 5 is released. Therefore, under the elastic action of the torsion spring 6, the U-shaped locking rod 5 is engaged in the tooth groove of the ratchet 3. The cooperation between the torsion spring 6 and the U-shaped locking rod 5 realizes the automatic locking of the ratchet 3, reducing manual intervention and improving operating efficiency. The mounting assembly 4 is fixed with screws through the insertion slot 1a. Combined with the symmetrical design of the U-shaped plate 41, the stability and vibration resistance of the overall structure are enhanced.

[0031] Furthermore, the intermediate rod of the U-shaped locking rod 5 is fixedly sleeved with a sleeve sleeve 51, which improves the stability of the engagement between the sleeve sleeve 51 and the tooth groove of the ratchet 3.
