Description
Technical field
This utility model is related to field of electrical equipment, specifically a kind of plugging device of cable tube.
Background technology
Cable inspection well generally connects multichannel cable tube located underground, including pre-setting by planning but not yet
The cable tube of cable is equipped with, the mouth of pipe position of these cable tubes needs installation block head to be closed, can thus stop dirt
Water, debris and worm Mus are entered inside cable tube.But adopting cement bonded sand work made of stones, sealing effectiveness less to manage existing block head more
Think, require further improvement.
Utility model content
The purpose of this utility model is to overcome the shortcomings of above-mentioned background technology, there is provided a kind of cable tube blank pipe closure dress
Put, the device should have that plugging effect is good, simple structure, it is easy for installation the characteristics of.
The technical solution of the utility model is：
Cable tube blank pipe plugging device, it is characterised in that：The device includes annular rubber ring, is separately positioned on rubber ring two
End face and outer plate in disk form and clip plate, by be connected outer plate and clip plate with force that rubber ring deforms at least one
Individual connector；It is formed respectively with the outer plate and clip plate for snapping in the outer lug boss and inner convex platform of rubber ring inner chamber, external pressure
The external diameter of internal diameter of the external diameter of plate more than cable tube, clip plate and rubber ring is respectively less than the internal diameter of cable tube.
The device also includes the check valve in outer plate with clip plate；In the inlet end of the check valve is arranged on
In the internal plug seat of pressing plate, the outlet side of check valve is arranged in the outer jack of outer plate.
The connector is bolt and the spiral shell for fitted bolt on being arranged on outer plate and clip plate axis direction
It is female；It is connected in the bolt hole of the bolt insertion outer plate and with the nut being arranged on clip plate.
The outer circumference surface of the rubber ring is formed with the bulge loop for extending and connecting lopping in a circumferential direction, the inner circle of rubber ring
Side face is formed with.
The beneficial effects of the utility model are：
This utility model not only has good plugging effect, has prevented worm Mus and has entered the possibility for damaging cable tube, has also increased
If check valve is used for the external and internal pressure of balanced cable pipe, it is to avoid because cable tube internal pressure increase of being heated causes this utility model
The axial displacement that may occur；Additionally, this utility model simple structure, installation is convenient to.

Specific embodiment
Below in conjunction with the embodiment shown in Figure of description, the utility model is described in further detail, but this utility model
It is not limited to following examples.
As shown in figure 1, blank pipe plugging device, including rubber ring 1, outer plate 2, clip plate 3, check valve 4, connector.Institute
Rubber ring is stated for annular, the outer circumference surface of rubber ring is formed with the bulge loop 11 and the rubber that extend and connect lopping in a circumferential direction
The inner peripheral surface of cushion rubber is formed with.
The outer plate is disc with clip plate.As shown in Figure 3 and Figure 4, the outer plate is arranged on cable tube 9
Mouth of pipe position, its right end face of outer plate are provided with the outer lug boss 21 of circle, and full thickness direction is additionally provided with outer plate
Outer jack 22 and bolt hole 23.(area of outer plate is more than in cable tube more than the internal diameter of cable tube for the external diameter of the outer plate
The cross section in chamber), the spiro keyhole position is on the axis of outer plate.As shown in Figure 3 and Figure 4, the clip plate is arranged on electricity
The inside of cable pipe, the left end face of the clip plate are provided with the inner convex platform 31 of circle, and clip plate is provided with full thickness side
To internal plug seat 32 and nut bore 33.Internal diameter and internal diameter less than cable tube of the external diameter of the clip plate more than rubber ring,
The nut bore is for hexagon and on the axis of clip plate.
The outer plate is separately mounted to the two ends of rubber ring with clip plate, is needed outer lug boss and inner convex platform point during installation
The inner chamber of rubber ring is not snapped in, as the edge portions of outer plate can cover the cross section of cable tube cavity, therefore effectively
Improve sealing effectiveness.
The connector is one or more (selecting as needed), for outer plate is connected as one with clip plate；
Connector is the bolt 5 and nut 6 for cooperating.As shown in Figure 3 and Figure 4, the bolt is turned left from the right side and is horizontally inserted outer plate
Bolt hole in, be connected then across rubber ring and with the nut in the clip plate nut bore, the axis direction of bolt and
Outer plate, rubber ring, the axis direction of clip plate overlap.Tighten bolt and can reduce the spacing of outer plate and clip plate and cause rubber
The two ends of cushion rubber are squeezed, and then cause the periphery of rubber ring to bulge and deform and so that bulge loop is adjacent in cable tube
On inwall.
The check valve is arranged in outer plate and clip plate, the axis side of the axis direction of check valve parallel to bolt
To.As shown in Figure 3 and Figure 4, the inlet end (right-hand member in figure) of the check valve is in the internal plug seat of clip plate, check valve
Outlet side pass through in the outer jack for stretching into outer plate after rubber ring from the right side level of turning left, inlet end and cable tube inner space,
Outlet side and ft connection.The check valve can be with the inner and outer air pressure of balanced cable pipe, it is to avoid this utility model is because in cable tube
Portion's pressure increase is produced and axial displacement.
