Description

Technical Field

[0001] The utility model relates to the technical field of power transmission, in particular to a cable anti-sagging device with a positioning function. Background Art

[0002] The transmission of electricity is inseparable from the installation of cables. The cables are fixed on the poles. After a period of time, the cables tend to loosen, giving people a visual sense of insecurity. However, in some uninhabited areas, people cannot find cables that need timely maintenance, causing some cables to sag severely and eventually break under the cable's own gravity, causing inconvenience to people's lives. Therefore, there is an urgent need for a cable anti-sagging device with a positioning function.

[0003] After searching, the Chinese patent publication number CN109888704B discloses a cable anti-sagging device with a positioning function. When the device is in use, the cable passes through the cable hole and is then fixed to the cable clamping block. The spring pulls the cable clamping block, which gives the cable a greater tension, thereby keeping the cable from sagging. The device also has a positioning function. When the positioning device is turned on, a signal is sent out. After receiving the signal, the power department repairs the cable that is severely sagging.

[0004] However, the technical solution in the above patent still has certain disadvantages. When the cable passes through the cable through-hole of the first fixed block, due to the lack of protection for the cable, the cable skin at the cable through-hole is easily worn or even cracked, affecting the use of the cable. Moreover, the cable clamping block only makes the cable have a large tension through the stretching effect of the spring. The spring is elastic, and the elasticity will decrease with the passage of time, resulting in insufficient tensile strength of the cable, poor cable anti-sagging effect, and insufficient practicality. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a cable anti-sagging device with a positioning function, which can prevent the cable skin from being worn or even cracked at the cable passage hole, ensure the use of the cable, effectively improve the tensile strength of the cable, enhance the anti-sagging effect of the cable, and improve the practicality.

A clamping screw is threadedly installed on the top of the block, and a knob is fixed on the top of the clamping screw. A holding rubber pad is rotatably connected to the bottom of the knob. The holding rubber pad is movably installed in the cable fixing groove, and the width of the fixed rubber pad and the holding rubber pad should be wider than the T-shaped slider. An adjusting screw is rotatably installed on the first fixed block and the second fixed block. A threaded hole is provided on the T-shaped slider. The T-shaped slider is mounted on the adjusting screw through a matching threaded sleeve of the threaded hole. A handwheel is fixed on the right end of the adjusting screw. A U-shaped groove is provided on the top of the second fixed block. Two sets of rotating shafts are symmetrically rotated on the U-shaped groove. One end of the cable passes through the cable protective cover, the cable fixing groove and the U-shaped groove in sequence, and the holding rubber pad is pressed against the cable.

[0008] Preferably, the threaded sleeve on the adjusting screw rod is provided with two sets of lock nuts, and the two sets of lock nuts are respectively located on the left and right sides of the T-shaped slider.

[0009] Preferably, a butterfly nut is threadedly mounted on the compression screw.

[0010] Preferably, a protective rubber pad is fixedly provided in the U-shaped groove at the top end of the second fixing block.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: when in use, one end of the cable is passed through the cable protective cover, the cable fixing groove and the U-shaped groove in turn, and the clamping screw is turned by the knob to make the clamping screw push the pressing rubber pad to press on the cable, so that the cable is clamped and fixed by the fixing rubber pad and the pressing rubber pad. After the cable is laid and straightened, the adjusting screw is turned by the hand wheel to make the adjusting screw drive the T-shaped slider to slide to the right along the T-shaped slide groove, and then the T-shaped slider pulls the cable to the right and tightens it, so that the cable is kept properly tensioned to prevent the cable from sagging. The protection of the cable by the cable protective cover can avoid wear and even cracking of the cable skin at the cable passing hole, thereby ensuring the use of the cable. After the cable is stretched by the T-shaped slider, the cable can maintain a stable tension, thereby effectively improving the tensile strength of the cable, enhancing the anti-sagging effect of the cable, and improving practicality.
