However, the existing column type composite insulator has the following defects: 1. the sealing performance of the composite material and the upper metal connecting piece and the lower metal connecting piece is poor, rainwater and the like easily enter the core rod from the space between the sheath and the upper metal connecting piece and the lower metal connecting piece, and the insulating performance is influenced; 2. the composite material has no elasticity, the connecting strength of the sleeve, the upper metal connecting piece and the lower metal connecting piece is low, the sheath is easily separated from the upper metal connecting piece or the lower metal connecting piece, and the service life of the insulator is shortened.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a column type composite insulator that insulating properties is good, long service life, corrosion resistance are good, be difficult to peck by birds.
In order to solve the above problem, the utility model discloses technical scheme that column type composite insulator adopted does: including the plug, have the first adapter sleeve of clamping screw, have fixation nut's second adapter sleeve, full skirt and sheath, insert respectively at the both ends of plug in first adapter sleeve and the second adapter sleeve be close to on the first adapter sleeve be provided with first annular groove plug one side be close to on the second adapter sleeve be provided with the annular groove of second on one side of the plug with the sheath medial surface that annular groove of first annular groove and second correspond is provided with the bulge loop, the bulge loop card is gone into correspondingly in the annular groove of first annular groove and the annular groove of second the bottom of annular groove of first annular groove and the annular groove of second is provided with along the ascending dentate sand grip of axis direction alternately.
The additional technical characteristics are as follows:
and water-swelling adhesive tapes are respectively arranged in the first annular groove and the second annular groove.
Compared with the prior art, the utility model provides a column type composite insulator has following advantage: the first connection sleeve comprises a core rod, a first connection sleeve with a fixed screw rod, a second connection sleeve with a fixed nut, an umbrella skirt and a sheath, wherein two ends of the core rod are respectively inserted into the first connection sleeve and the second connection sleeve, a first annular groove is arranged on one side, close to the core rod, of the first connection sleeve, a second annular groove is arranged on one side, close to the core rod, of the second connection sleeve, a convex ring is arranged on the inner side face of the sheath corresponding to the first annular groove and the second annular groove, the convex ring is clamped into the corresponding first annular groove and the second annular groove, toothed convex strips in the axial direction are alternately arranged at the bottoms of the first annular groove and the second annular groove, the umbrella skirt and the sheath are made of high-strength corrosion-resistant polycarbonate materials, and the convex ring is clamped in the first annular groove and the second annular groove, the sheath is connected with the first connecting sleeve and the second connecting sleeve more firmly, when the sheath or the umbrella skirt is impacted from outside, the sheath and the umbrella skirt cannot be separated from the first connecting sleeve and the second connecting sleeve, the convex rings are clamped in the first annular groove and the second annular groove, rainwater is prevented from entering the core rod, and toothed convex strips in the axial direction are arranged at the bottoms of the first annular groove and the second annular groove at intervals, so that the bottoms of the first annular groove and the second annular groove are engaged with the top of the convex rings in a concave-convex mode, and the connecting strength and the impact resistance are further improved; and secondly, because the water-swelling adhesive tapes are respectively arranged in the first annular groove and the second annular groove, when rainwater and the like enter the first annular groove and the second annular groove, the water-swelling adhesive tapes can swell when meeting water, so that the sealing effect is further realized, and the sealing effect is better.
