Abstract
The utility model provides a mouth plugging device of a cable pipe, which comprises a sealing column with an inner baffle at one end, an outer annular baffle, a sealing gas washer and a nut, wherein the outer annular baffle and the sealing gas washer are respectively sleeved on the sealing column; the sealing gas washer is between the outer annular baffle and the inner baffle; an external thread is arranged on the other end of the sealing column corresponding to the inner baffle; the nut and the sealing column are in threaded connection; a cable through hole is arranged on the sealing column along the central axis direction; the inner baffle is an inner annular baffle; the cable through hole is arranged corresponding to the inner ring of the inner annular baffle; and the outside diameter of the outer annular baffle is more than that of the inner annular baffle. The mouth plugging device of the cable pipe disclosed by the utility model has the advantages of being scientific in design, free from mud plugging, convenient for assembly and disassembly and good in plugging effect.
Description
Technical field
The utility model relates to a kind of pencil manufacturing equipment, specifically, has related to the cable mouth plugging apparatus in a kind of pencil manufacturing equipment.
Background technology
At present cable duct antiseep shutoff commonly used is to adopt the stifled mudding of fire prevention stifled, and according to the situation of long-term use, mainly have following problem: 1, shutoff length is too short, cause and infiltrate a lot of water in the penetration pipe, when the too much hydraulic pressure of ponding was excessive simultaneously, the stifled mud of fire prevention can be rushed to open, and causes shutoff to lose efficacy; If the stifled mud filling of 2 fire prevention is too much, although the problem that has solved seepage and gone out by ponding can cause when backup line comes into operation, the stifled mud of filling is difficult to take out, and causes simultaneously the uneconomical of cost.
In order to solve the problem of above existence, people are seeking a kind of desirable technical solution always.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, thereby a kind of design science is provided, does not need stifled mud, is convenient to mount and dismount, cable mouth plugging apparatus that plugging effect is good.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of cable mouth plugging apparatus, and it comprises that an end is provided with the sealing column of Internal baffle, annular outer baffle, blanket gas packing ring and nut; Described annular outer baffle and described blanket gas packing ring are set on the described sealing column, and described blanket gas packing ring is between described annular outer baffle and described Internal baffle; The other end with respect to described Internal baffle on the described sealing column is provided with external screw thread, and described nut and described sealing column are threaded.
Based on above-mentioned, described sealing column is provided with cable through-hole along its central axial direction, and described Internal baffle is annular Internal baffle, the interior ring setting of the corresponding described annular Internal baffle of described cable through-hole.
Based on above-mentioned, the external diameter of described annular outer baffle is greater than the external diameter of described annular Internal baffle.
The relative prior art of the utility model has substantive distinguishing features and progress, and specifically, the utility model replaces traditional stifled mud with the blanket gas packing ring, effectively shutoff cable duct, and can as blocking up mud, do not washed out by ponding; Unclamp nut and can remove shutoff, can as stifled mud, not finalize the design and not come out.The advantage that this cable mouth plugging apparatus has design science, do not need stifled mud, be convenient to mount and dismount, plugging effect is good.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the structural representation of embodiment 2.
Among the figure: 1. Internal baffle; 2. sealing column; 3. annular outer baffle; 4. blanket gas packing ring; 5. nut; 6. external screw thread; 7. cable through-hole; 8. cable tube.
Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of cable mouth plugging apparatus, it comprises that an end is provided with the sealing column 2 of Internal baffle 1, annular outer baffle 3, blanket gas packing ring 4 and nut 5; Described annular outer baffle 3 and described blanket gas packing ring 4 are set on the described sealing column 2, and described blanket gas packing ring 4 is between described annular outer baffle 3 and described Internal baffle 1; The other end with respect to described Internal baffle 1 on the described sealing column 2 is provided with external screw thread 6, and described nut 5 and described sealing column 2 are threaded.Described Internal baffle 1, described sealing column 2, described annular outer baffle 3 and described nut 5 all adopt metal material, and described blanket gas packing ring 4 adopts the suitable material such as fire-resistant rubber.
The external diameter of described annular outer baffle 3 is greater than the external diameter of described annular Internal baffle.
According to described Internal baffle 1 inwardly described annular outer baffle 3 direction outwardly this cable mouth plugging apparatus is placed into the mouth of pipe of cable tube 8, described annular outer baffle 3 is propped up on the mouth of pipe of described cable tube 8, then turn described nut 5 according to the direction of tightening, make between described Internal baffle 1 and the described annular outer baffle 3 apart from reducing, and then compress described blanket gas packing ring and make it to produce deformation, seal up described cable tube 8.If when removing, only need to unscrew described nut 5, make distance increase between described Internal baffle 1 and the described annular outer baffle 3, described blanket gas packing ring no longer seals described cable tube 8 because losing extruding force from new reinstatement.
Should be noted that at last: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
