Description

Technical Field

[0001] The utility model relates to the technical field of wire fixing, in particular to a manual self-locking device. Background Art

[0002] When wiring cables, the ends of the cables need to be fixed to complete the wiring. Currently, a locking ring is usually used to rotate the ends of the cables and lock the fitting parts to fix the cables. However, this method requires the cooperation of multiple people, pulling the ropes hard, and even using tools such as wrenches, which is complicated to operate. Especially when tightening the wires at high altitudes, on the one hand, you need to hold the power tower with both hands at all times to ensure your own safety, and on the other hand, you need to hold the wrench with both hands to tighten the wires. This is very dangerous, time-consuming, labor-intensive, low-efficiency, high labor intensity for operators, and limited by the working environment of the construction site. Therefore, it is extremely necessary to design a safe and practical manual self-locking device that is easy to tighten the wires. Utility Model Content

Both the fixed clamping block 6 and the movable clamping block 7 are provided with a semicircular clamping opening 11, which is used to clamp the cable.

[0036] The slide block 2 moves left and right on the gear rod 1, driving the movable clamping block 7 to move closer to or farther from the fixed clamping block, thereby tightening or loosening the clamping inlet.

[0037] The articulated seat 4 rotates, driving the gear 3 to rotate, so that the gear 3 can mesh and transmit on the teeth.

[0064] How it works:

[0065] against Figure 5 and Figure 6 Viewing angle:

[0066] When tightening is required, hold the left handle 10 with the left hand and the right handle 5 with the right hand, turn the right handle 5 to the left, drive the hinge seat 4 to rotate counterclockwise around the first screw 301 as the axis, drive the gear push block 8 to rotate, make the push plate 803 abut the gear 3 while pushing the gear 3 to rotate, the gear 3 meshes on the gear rod 1 and moves closer to the left handle 10, the movable clamping block 7 approaches the fixed clamping block 6, the clamping inlet gradually decreases and tightens, wherein, when the gear 3 moves to the left, the gear check block 9 always provides a left force under the action of the check torsion spring 801 to prevent the gear 3 from rotating.

[0067] When it is necessary to loosen, turn the right handle 5 clockwise to make the hinge seat 4 rotate clockwise, driving the gear push block 8 to rotate clockwise, so that the push plate side plate 802 is mortgaged to the gear check block 9. At this time, the protrusions of the push plate 803 and the check plate 902 are both out of the gear, and the gear 3 is not subjected to any force at this time. Then move the right handle to the right to make the movable clamping block 7 move away from the fixed clamping block to complete the loosening.

[0068] The beneficial effects of the utility model are as follows: the utility model drives the hinged seat 4 to rotate by rotating the right handle, drives the gear pushing block 8 to push forward, drives the movable clamping block 7 to move forward and form a tight clamping mouth; since the cross section of the cable is circular, a semicircular clamping mouth 11 is provided to adapt to the shape of the cable, which can better fit the cable, make the clamping more stable and the clamping operation simple and convenient; by providing a gear check block 9, the gear 3 is prevented from rotating, so that it is not easy to loosen after clamping, and the clamping force is guaranteed; by the rotation design of the right handle 10, a lever principle is formed with the hinged seat 4 as the fulcrum, so that effort can be saved when rotating; by providing an O-ring and a safety belt, it is safe and practical to prevent the occurrence of falling during high-altitude operations.
