The ear body 1 is provided with both legs having an outwardly expanding elasticity and has a U-shape, and the vicinity of the bending base of each leg is a wide portion 1a. The retaining sleeve 2 is provided with a screw rod portion 2a capable of penetrating a hole formed in the base side of the main body, a collar 2b which is locked in the hole and can be applied by a spanner, and a sleeve portion 2c in this order, and is centered over the entire length. A hole 2d is drilled. The square nut 3 is non-rotatably inserted into the wide portion, and has a screw hole at the center for screw rod portion 2a.
Screw together. The hanger bar 4 penetrates the center hole of the detent sleeve 2 and has a nodule 4a at its lower end. The square bolt 5 penetrates a square hole formed in the center of both legs of the main body, but the tail end forms a flat portion 5a, and the flat portion penetrating the square hole has a relationship with the square hole so that its surface is horizontal. is there. One end of the lever 6 forms a clevis, and this portion is pivotally attached to the flat portion 5a by a pin 7. Further, the outer circumference of the clevis is formed on a cam surface in which the distances from the center of the pin 7 to one side, the outer end, and the other side of the clevis portion change from small to large as r1, r2, and r3, respectively.

状態となる。The present invention is constructed as described above. The square nut 3 is inserted into the wide portion 1a, the detent sleeve 2 is screwed, and the base of the main body is tightly clamped by the flange and the square nut. The hanger bar 4 puts the nodule down and inserts the other end into the detent sleeve 2 to bring the nodule into contact with the square nut. Then, the sleeve 2c is crimped to the hanger bar. The upper end of the hanger bar is a suspended wire (not shown)
Lock to. When the r1 part contacts the body leg part, the lever 6 can insert the electric train line T between both teeth of the ear, and when the r2 part contacts (Fig. 2), temporarily fixes it, and when the r3 part contacts, It will be in a tightened state.

案の特徴である。[Effect] A locking device in which teeth are provided at both ends of a U-shaped body having an inner concavity and elasticity is known from Japanese Utility Model Publication No. 38-15829. A hanger bar is inserted into the hole on the base side of the main body, and the bottom end bulges to prevent it from coming off.
The trolley wire grip depends only on the elasticity of the legs. With this structure, it is difficult to avoid generation of corona from the engaging portion between the main body and the hanger bar due to vibration when the vehicle passes. In addition, it is impossible to avoid the fear of the trolley wire falling out due to unexpected vibration. On the other hand, in the present invention, since the hanger bar and the main body are completely integrated, there is no room for corona generation. Since both legs are firmly tightened with the through bolts, there is no fear of the trolley wire falling off. The above is the feature of the present invention.
