Description

Plugging device for column tube
Technical Field
The utility model relates to a post pipe shutoff technical field, concretely relates to plugging device of post pipe.
Background
Cables are widely used in the fields of power and communications as a common component in modern industries. After the cable penetrated the pillar pipe, can have the space between the mouth of pipe of pillar pipe and the cable, if not carrying out the shutoff, had the rainwater entering pillar pipe, though the pillar pipe often can set up the drain pipe, but a long time has entering pillar pipe such as dust, toy, leaf and blocks up the wash port, leads to the cable bubble in water, not only influences cable life, still can arouse incident such as electric leakage. In prior art, solve the shutoff problem of the column casing mouth of pipe and often can adopt fire prevention mud to carry out the shutoff, nevertheless fire prevention mud ftractures easily and drops, and sealed effect is not good to often need the user to block up again.
In such a technical context, part of users use cable plugs to plug the column tubes. Cable closers often include an annular seal and first and second pressure plates disposed on opposite sides of the annular seal and secured to the three components using fasteners such as screws. However, the hardware structure has certain defects, the sealing effect of the first pressing plate and the annular sealing element and the sealing effect of the second pressing plate and the annular sealing element are not ideal, and the fitting degree is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a plugging device of column jacket in order to solve the not enough of above-mentioned technique, make the effective shutoff in space between cable and the column jacket, prevent that water or debris from getting into the column jacket.
In order to achieve the purpose, the utility model discloses a plugging device of column casing, including the plugging device body of awl section of thick bamboo shape, what the plugging device body adopted is flexible material, is provided with the fracture on the section of thick bamboo wall of axial plugging device body, the broken line position of plugging device body inner wall sets up with the broken line position of plugging device body outer wall is crisscross to the line disconnection between the broken line of inner wall and the broken line of outer wall forms the fracture, the main aspects port of plugging device body is used for the parcel at the surface of column casing port and cramps with the clamp, the tip port of plugging device body is used for the parcel at the surface of cable and cramps with the clamp.
Above-mentioned technical scheme expands the occluder body along the fracture, and big end port parcel is tightened up and is cramped fixedly at the surface of column casing with the clamp, and the tip port parcel is tightened up and is cramped fixedly at the surface of cable with the clamp. When the outer diameter of the column pipe or the cable is smaller than the inner diameter of the corresponding port of the plugging device body, after the plugging device body tightly wraps the column pipe or the cable, a part of the overlapped cylinder wall of the plugging device body can be cut off, and then the cylinder wall is clamped by a clamp; when the external diameter of a column tube or a cable is larger than the internal diameter of a corresponding port of the occluder body, due to the staggered fracture design of the occluder body, the diameter of the occluder body can be enlarged by reducing the overlapped part of the fracture, and the cylinder wall at the fracture position can be used after the occluder body tightly wraps the column tube or the cable. The utility model discloses make the space shutoff between cable and the pillar pipe, the laminating is effectual, prevents effectively that rainwater or debris from getting into the pillar pipe, has improved the life and the security of cable. The staggered fracture structure enables the plugging device of the same type to be suitable for column tubes and cables of different diameters, and is high in applicability and wide in application range.
Preferably, the occluder body is formed by arranging a plurality of straight cylindrical shell sections with different diameters from small to large and sealing and connecting the shell sections. The straight cylindrical shell section is convenient for hooping by a hoop and is not easy to slip and fall off.
Preferably, the outer surfaces of the end parts of the two ends of the stopper body are both provided with a circle of raised edges. The design of the edge can prevent the end part of the stopper from falling off after the clamping hoop is tightened.
Preferably, the flexible material is rubber. The rubber material has excellent elasticity and low price, can wrap and plug cable column pipes with different sizes, and has excellent sealing property.
The plugging device for the column tube has good laminating effect by effectively plugging the gap between the cable and the column tube, prevents rainwater or sundries from entering the column tube, and improves the service life and the safety of the cable; the staggered fracture structure enables the plugging device of the same type to be suitable for column tubes with different diameters, and the applicability is strong; the rubber material is used, so that the manufacturing cost is low, and the sealing property is good.
