The internal diameter of the size of draw-in groove 15 and penetration pipe 2, external diameter and wall thickness are complementary;
Inner tubal wall free-end and inner tubal wall 14 are level and smooth cambered surface with the outside of roof 13 junctions.
The cross section outline of preferred holder is the dodecagon of band fillet.
The holder inwall can be provided with internal thread 18, this cable protection sleeve that is used for penetration pipe is fixed on end has externally threaded penetration pipe.
When the holder inwall is not established internal thread, can take following method:
Being provided with two positions symmetry in the radial direction and penetrating the fixing hole 17 of holder tube wall of holder, the fixing hole inwall is established internal thread, is complementary with jackscrew.Jackscrew is screwed on the fixing hole, and the cable protection sleeve that this can be used for penetration pipe is fixed on the end of penetration pipe.
Perhaps, holder is provided with the fixing hole 17 that three spacings equate, fixing hole 17 penetrates the tube wall of holder, and the fixing hole inwall is provided with internal thread, is complementary with jackscrew.Jackscrew is screwed on the fixing hole, and the cable protection sleeve that this can be used for penetration pipe is fixed on the end of penetration pipe.
Holder be provided with the earth terminal fixing hole in the radial direction, the earth terminal fixing hole penetrates the tube wall of holder, and is provided with internal thread in the earth terminal fixing hole, can be used for the dead earth terminal.
Material can be selected the stainless steel or the carbon steel of the higher and wear resistant corrosion resistant of intensity for use, perhaps has the stainless steel or the carbon steel of nickel coating or multicolored zinc layer.
Earlier this cable protection sleeve is fixed on the end of penetration pipe during use, again cable is passed penetration pipe and sleeve gets final product.
Because the penetration pipe end is placed in the draw-in groove, the burr of penetration pipe end or irregular otch can not touch cable like this; And the outside of inner tubal wall free-end that contacts with cable and inner tubal wall and roof junction is level and smooth cambered surface, and cable can be by scratch and wearing and tearing like this.
This cable protection sleeve can be used for protecting various indoor or outdoor cables, and as electric wire, cable, telephone wire, holding wire or optical cable etc., cable is not easy by scratch or wearing and tearing when passing penetration pipe and in the use like this; And strength of materials height, wear resistant corrosion resistant, the outward appearance exquisiteness, long service life can also satisfy the requirement of ground protection.
