Abstract
The invention relates to a device for sealing and blocking wire through hole on a wall or a cabinet body. A sealing elastic body is tightly embedded between outer rim of a wire tube and inner rim of an open hole, two ends of the sealing elastic body extend out from end faces of two ends of the open hole to be respectively in compression joint with an end cover; the two end covers are fixed with the sealing elastic body through at least two split bolts, and the sealing elastic body is tightly pressed, expanded and embedded by the end covers and the split bolts between the wire tube and the open hole. In the device of the invention, the external diameter of the sealing elastic body is slightly greater than the internal diameter of the open hole, when the wire tube is in place, the split bolts are equipped, then annular bosses of the end covers are embedded in annular grooves of the ends of the sealing elastic body, therefore the sealing elastic body is extruded and expanded, the part between the open hole and the wire tube is filled well, the annular rings formed at two ends of the sealing elastic body are in compression joint with surfaces of two sides of the open hole and are tightly pressed by the end covers, so as to further improve the sealing of the open hole; a plurality of sealing fins are coaxially made on the inner rim of the sealing elastic body so that the sealing is better.
Description
Technical field
The present invention relates to plug-hole construction applications, especially a kind of wall or cabinet threading hole seal plug aperture apparatus when light current or forceful electric power wiring.
Background technique
Light current or forceful electric power construction are the important steps in construction and decoration, its make network and electrical network unobstructed, meet the needs of people's Working Life, in new building, the cable that light current and forceful electric power relate to, electric wire is generally laid in wire casing, these wire casings are arranged with the contraposition of cabinet phase through the end of wall, cable in it, equipment connection in electric wire and cabinet, but in the transformation of old building, need perforate on wall and cabinet, then by cable, electric wire is through this some holes, again with the equipment connection in cabinet, in order to protect cable, electric wire, cable tubing must be overlapped, internal diameter due to perforate is greater than the external diameter of spool, so after spool passes, gap can be left on wall and cabinet, do not meet job specfication like this, some producer develops the hole plugging device of perforate, but find in practice, plugging effect is not fine.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide extrusion expansion and can fill gap between perforate and spool a kind of wall or cabinet threading hole seal plug aperture apparatus.
The technological scheme that the present invention takes is:
A kind of wall or cabinet threading hole seal plug aperture apparatus, comprise perforate and spool, spool interval is inlaid in perforate, it is characterized in that: tight setting-in elastic sealed body between described spool outer rim and perforate inner edge, the end face that perforate two ends are stretched out at the two ends of this elastic sealed body crimps an end cap respectively, these two end caps and sealing elastomer are fixed by least two split bolts, and described elastic sealed body is compressed expansion and is inlaid between spool and perforate by described end cap and split bolt.
And, described sealing elastomer is made up of two-part, these two-part are adjacent is sleeved on spool outer rim and this two-part outer rim is closely crimped on the inner edge of perforate, two end faces that these two-part stretch out perforate both sides make an annular groove respectively, the annular boss that in each annular groove, setting-in homonymy end cap is made, described split bolt is installed in two end caps, two annular boss, described two-part.
And the end outer rim that described two-part stretch out perforate both sides all makes an outward extending annular ring, this annular ring is crimped on the surface of perforate both sides and should be compressed by described end cap outer side bottom surface.
And, described sealing elastomer inner edge is made multiple sealing fin coaxially.
Advantage of the present invention and good effect are:
In the present invention, the bipartite sealing elastomer of coaxial adjacent suit between perforate and spool, the elastomeric external diameter of sealing is slightly larger than perforate internal diameter, first in perforate, sealing elastomer is set with, then spool is passed but, while penetration pipe, end cap is enclosed within spool, when spool is in place, split bolt is installed, make in the annular groove of annular boss embedding sealing elastomer end of end cap, thus by sealing elastomer extrusion expansion, by populated between perforate and spool, the annular ring that sealing elastomer two ends are made is crimped on the surface of perforate both sides and is compressed by end cap, further increase the sealing of perforate thus, multiple sealing fin is coaxially made in sealing elastomer inner edge, make better tightness.

Fig. 2 is the structural representation that Fig. 1 removes spool.
Embodiment
Below in conjunction with embodiment, the present invention is further described, and following embodiment is illustrative, is not determinate, can not limit protection scope of the present invention with following embodiment.
A kind of wall or cabinet threading hole seal plug aperture apparatus, as shown in Fig. 1 ~ 2, comprise perforate 12 and spool 8, spool interval is inlaid in perforate, innovation of the present invention is: tight setting-in elastic sealed body 2 between described spool outer rim and perforate inner edge, the end face that perforate two ends are stretched out at the two ends of this elastic sealed body crimps an end cap 4 respectively, these two end caps and sealing elastomer are fixed by least two split bolts 7 and nut 6, and described elastic sealed body is compressed expansion and is inlaid between spool and perforate by described end cap and split bolt.
In the present embodiment, described sealing elastomer is made up of two-part, these two-part are adjacent is sleeved on spool outer rim and this two-part outer rim is closely crimped on the inner edge of perforate, two end faces that these two-part stretch out perforate both sides make an annular groove 11 respectively, the annular boss 5 that in each annular groove, setting-in homonymy end cap is made, described split bolt is installed in two end caps, two annular boss, described two-part.
The end outer rim that described two-part stretch out perforate both sides all makes an outward extending annular ring 3, and this annular ring is crimped on the surface of perforate both sides and should be compressed by described end cap outer side bottom surface.Described sealing elastomer inner edge is made multiple sealing fin 13 coaxially.
Label 1 in figure can wall, also can be the cabinet of light current or forceful electric power erection unit, namely can realize the isolation inside and outside the isolation at wall two ends or cabinet, make endoporus 9, end cap is made exit orifice 10, endoporus and the embedded cable tubing of exit orifice in elastic sealing cover topic.
In the present invention, the bipartite sealing elastomer of coaxial adjacent suit between perforate and spool, the elastomeric external diameter of sealing is slightly larger than perforate internal diameter, first in perforate, sealing elastomer is set with, then spool is passed but, while penetration pipe, end cap is enclosed within spool, when spool is in place, split bolt is installed, make in the annular groove of annular boss embedding sealing elastomer end of end cap, thus by sealing elastomer extrusion expansion, by populated between perforate and spool, the annular ring that sealing elastomer two ends are made is crimped on the surface of perforate both sides and is compressed by end cap, further increase the sealing of perforate thus, multiple sealing fin is coaxially made in sealing elastomer inner edge, make better tightness.
