Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.

As shown in Figure 1 to Figure 3, a multi-directional cable distance extender, including

The main base ring 1 and two expansion parts;

The spreader includes a spreader screw 2 and a lock hoop 3 arranged on the spreader screw. The main base ring is provided with a number of first threaded holes that can be threadedly connected with the spreader screw. The axis of the first threaded hole is vertical On the axis of the main base ring, the first threaded holes are distributed sequentially along the circumference of the main base ring

The lock hoop includes a fixed half hoop 31, a movable half hoop 32, a fixed plate body 33, a movable plate body 34 and a lock hoop screw 35. The plate body is connected, the other end of the movable half hoop is connected with the moving plate body, the locking hoop screw passes through the fixed plate body and the moving plate body, the locking hoop screw is threaded with the fixed plate body, and the locking hoop screw is threaded with the moving plate body;

The expansion parts correspond to the first threaded holes one by one. In the corresponding expansion parts and the first threaded holes: the first threaded hole is threadedly connected with the expansion screw, and one end of the expansion screw is connected with the fixed half hoop.

When the wire needs to be stretched, open the two lock rings (remove the lock screw and separate the fixed half ring and the moving half ring), lock one of the wires with one lock ring, and use the other lock ring The strut of the wire can be realized by locking the other wire with the hoop. Since the first threaded hole is threadedly connected with the spreader screw, the distance between the lock ring hoop and the main base ring can be adjusted by rotating the spread screw rod. Therefore, within a certain range, the distance between the two lock ring hoops can be properly adjusted, thereby enabling Adapt to more different brace distances.

In the corresponding expansion member and the first threaded hole: the expansion screw passes through the first threaded hole, and the other end of the expansion screw is located in the central hole of the main base ring. The spreading screw rod passes through the entire first threaded hole, so that the adjustable range of the spreading screw rod is greatly increased, and the utility model can adapt to a larger range of spreading distance.

The axes of all the first threaded holes are coincident, and the axes of the first threaded holes intersect with the axis of the main base ring.

It also includes a hook, the main base ring and the hook are connected through a connecting cable 11, and the hook is made of insulating material. Hook can be made of any conventional insulating material such as wood, plastics. After the two wires are stretched, the weight of the utility model is all borne by the two wires that are stretched, which will cause the wires to bend downward. And the hook can be hung on nearby power pole towers or other wires, etc., and the structure hooked by the hook can share a part of the weight of the utility model, so as to avoid the excessive stress of the two wires that are strutted. Pay attention to ensure that the connecting cable is in a tensioned state, otherwise the hook cannot play its due role. In actual use, if the connecting cable is too long, the connecting cable can be shortened appropriately (for example, a part of the connecting cable can be wound around the on the hook, or partially knot the connecting cable).

The fixed half hoop is provided with a fixed spring pad 41, and the movable half hoop is provided with a dynamic spring pad 42. The fixed spring pad and the dynamic spring pad are symmetrically arranged, and the fixed spring pad is in the center hole of the main base ring. In the central hole of the main base ring. After the lock hoop locks the cable, if the diameter of the cable is less than the inner diameter of the lock hoop, the utility model is easy to slide or shake, and the cable is also easy to shake. The existence of the fixed spring pad and the movable spring pad can allow the utility model to adapt to more cables of different diameters, thereby ensuring a tight connection between the lock hoop and the cable, avoiding the sliding of the utility model, and avoiding excessive shaking of the cable during construction.

The first air cavity is provided in the fixed elastic pad, and in a stretching member: the stretching screw rod is provided with an elastic air bag 5, the elastic air bag is provided with an air inlet and an air outlet, and the air inlet is provided with an air intake unit. To the valve, the air outlet is provided with an air outlet one-way valve, and the air outlet is connected to the first air chamber through an inflatable tube 51. The direction that the air inlet one-way valve can pass is from the outside to the elastic air bag, and the air outlet one-way valve can pass through the elastic air bag. The passing direction is from the inside of the elastic air bag to the inflatable tube, the fixed bomb pad is provided with an exhaust pipe, and the fixed plate body is provided with an exhaust duct 33a, one end of the exhaust duct is the intake end, and the other end of the exhaust duct is the exhaust end. The intake end is connected to the first air chamber through the exhaust pipe, and the movable plate body is provided with an elastic gasket 6, which is attached to the fixed plate body, and the elastic gasket seals the exhaust end.

A second air chamber is provided inside the rolling cushion, and the first air chamber communicates with the second air chamber through an elastic air tube 52 . The dynamic elastic pad is also inflatable, and because the fixed elastic pad and the dynamic elastic pad are symmetrically arranged, the two elastic pads can be bulged together to compress the cable, the structure is better balanced, and the compression and fixing effect on the cable is also better. The application of the elastic air tube can ensure that the fixed half hoop and the movable half hoop can be opened smoothly, and the elastic air tube will not be damaged when the fixed half hoop and the movable half hoop are opened.

After the cable is locked by the locking ring, the elastic airbag can be repeatedly pressed and released. When the elastic airbag is pressed, the air in the elastic airbag enters the first air cavity through the inflation tube (air outlet one-way valve), and then enters the second air cavity through the elastic air tube , The fixed elastic cushion and the dynamic elastic cushion are inflated and bulged. When the elastic airbag is released, the elastic airbag automatically resets and bulges due to its elasticity. After inflating the fixed elastic pad and the dynamic elastic pad several times, the fixed elastic pad and the dynamic elastic pad will compress the compression cable together. It should be noted that only after the fixed plate body and the movable plate body are locked (that is, after the lock ring hoop is locked and the elastic gasket seals the exhaust end), the fixed spring pad and the dynamic spring pad can be inflated, otherwise the air will flow from the exhaust Airway leaks. After the utility model is used, there is no need to perform the deflation operation, and the lock ring hoop is directly opened, the fixed plate body and the movable plate body are separated (the elastic sealing pad leaves the exhaust end), and the air in the fixed spring pad and the dynamic pad is automatically released from the exhaust passage. freed.
