Description
Technical field
The utility model relates to field of electrical equipment, particularly a kind of crack resistence wall bushing.
Background technology
Wall bushing be for pipeline through receiving vibration or having the Hardware fitting of building walls of tight waterproof requirement, be usually used in the units such as building, chemical industry, iron and steel, running water, sewage disposal.Sleeve pipe wear concrete construction shear wall basis, Chuan Liang, when wearing special-shape column, should install simultaneously with civil engineering.Reason is, after reserving hole, the bad process of the second pouring between sleeve pipe and concrete, what have cannot process, as rigidity wall bushing installed by basement base concrete shear wall.
The most simplicity of design of existing wall bushing, and the thermal coefficient of expansion of shell material is different from the thermal coefficient of expansion of body of wall, the not reserved stroke of common wall bushing, change according to the season several times in the summer in winter, because dilation amount is different, often easily ftractures, thus cause electric leakage accident.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of crack resistence wall bushing, by the wall pre-embedded pipe in outer setting bellow-shaped, inside arranges the waterproof bushing pipe of bellow-shaped, and metope baffle plate is set at two ends, with reserved enough expansions and shrink space, prevent sleeve pipe from being leaked electricity by body of wall drawing crack, ensure the fail safe of this wall bushing.
For achieving the above object, the utility model provides following technical scheme: a kind of crack resistence wall bushing, it is characterized in that: described crack resistence wall bushing comprises the wall pre-embedded pipe of bellow-shaped, wall pre-embedded pipe inside is provided with the waterproof bushing pipe of bellow-shaped, waterproof bushing pipe is by the inwall of adhesives at wall pre-embedded pipe, the two ends of wall pre-embedded pipe are provided with two measure-alike discoidal metope baffle plates, columniform conductive core pole is provided with in waterproof bushing pipe, conductive core pole two ends are equipped with the binding post of sheet, binding post stretches out wall pre-embedded pipe outside through the metope baffle plate at two ends, and two binding posts are provided with at least two through wires holes respectively.
Preferably, described wall pre-embedded pipe is manufactured by stainless steel.
Preferably, described waterproof bushing pipe is manufactured by electro-insulating rubber.
Preferably, described metope baffle plate is manufactured by ceramic material, and the diameter of metope baffle plate 10cm at least larger than the diameter of wall pre-embedded pipe.
Preferably, the binding post of described conductive core pole and its both sides is by brass manufacture, and conductive core pole and two binding posts are monolithic construction.
The beneficial effect of above technical scheme is adopted to be: the wall pre-embedded pipe inside of this crack resistence wall bushing is provided with the waterproof bushing pipe of bellow-shaped, waterproof bushing pipe is by the inwall of adhesives at wall pre-embedded pipe, the two ends of wall pre-embedded pipe are provided with two measure-alike discoidal metope baffle plates, columniform conductive core pole is provided with in waterproof bushing pipe, conductive core pole two ends are equipped with the binding post of sheet, and two binding posts are provided with at least two through wires holes respectively.During use, wall pre-embedded pipe and metope baffle plate are embedded in body of wall, power transmission line is connected by the through wires hole on binding post, wall pre-embedded pipe and the waterproof bushing pipe telescopicing performance of bellow-shaped design are good, tear this wall bushing after can effectively preventing body of wall from expanding with heat and contract with cold, prevent the generation of leaky.
