Technical Field
The utility model relates to cable duct hole plugging technique, in particular to cable duct dead hole plugging device.
Background
In power cabling projects, it is often necessary to thread cables through building walls or pipe gallery walls. Usually, in order to facilitate the cable to pass through the wall body, a plurality of PVC pipes are pre-embedded during the wall body construction, and are used as through holes for the cable to pass through the wall body, namely cable pipe holes. However, when the cable is actually laid, not all the cable duct holes are used at one time, and some of the cable duct holes may need to be reused when other cables are laid later, so-called cable duct holes. In order to prevent other impurities from entering the cable duct holes, or to allow animals such as mice to enter and exit the building through the cable duct holes or crawl everywhere in the pipe gallery, the cable duct holes need to be blocked by adopting a blocking device. Patent No. CN 201520735082.4's utility model provides a pipeline hole plugging device, be exclusively used in the shutoff of cable duct hole vacancy. But the problems of complex structure, difficult processing of the elastic material body of the key part, limited plugging effect and the like exist.
Obviously, the cable duct empty hole plugging device in the prior art has the problems of complex structure, difficult processing of key parts of elastic materials, limited plugging effect and the like.

Drawings
Fig. 1 is a schematic structural view of the cable duct void plugging device of the present invention;
fig. 2 is a schematic view of a semicircular combined structure of an end cover of the cable duct empty hole plugging device of the utility model;
fig. 3 is a view of the gap of the rubber sealing tubular column tube wall of the cable duct empty hole plugging device of the utility model.
The cable duct empty hole plugging device of the present invention will be further described with reference to the accompanying drawings and the following detailed description.
Detailed Description
Fig. 1 is the structural schematic diagram of the cable duct empty hole plugging device of the present invention, in the figure, 1 is a left end cap, 2 is a rubber seal, 2-1 is a semicircular sealing ring, 3 is a right end cap, and 4 is a tension bolt. According to the drawing, the utility model discloses cable conduit hole plugging device includes: the left end cover 1, the right end cover 3 and the rubber seal 2; the left end cover 1 is a rigid tubular cylinder, and an annular boss is arranged on the right end face of the tubular cylinder; the right end cover 3 is a rigid tubular cylinder, and the left end face of the tubular cylinder is provided with an annular boss; the rubber seal 2 is an elastic tubular cylinder, the left end of the inner circle of the tube wall of the tubular cylinder is matched with the outer circle of the annular boss of the left end cover, the right end of the inner circle of the tube wall of the tubular cylinder is matched with the outer circle of the annular boss of the right end cover, and the middle part of the tubular cylinder is provided with an arc-shaped vacancy which is radially protruded outwards. When specifically using, diameter according to the cable duct pore is selected the size and is suitable the utility model discloses cable duct pore plugging device, with left end cover, sealing rubber and right-hand member end cover suit in proper order on the cable, place at cable duct pore suitable position, make distance between left end cover and the right-hand member lid diminish gradually through tie bolt, extrusion rubber is sealed. Because the middle part of the inner circle of the rubber sealing pipe wall is provided with the arc-shaped vacancy which is radially protruded outwards, under the action of extrusion force, two pipe walls of the rubber sealing tubular column body are expanded outwards to form a waist drum shape until the whole cable pipeline hole is plugged, so that the cable pipeline hole is plugged.
In order to improve the plugging effect, the right end of the excircle of the rubber sealing tubular cylinder is provided with a plurality of sealing rings 2-1 which are radially convex and have semicircular cross sections. The sealing ring is arranged, so that the rubber seal can adapt to the inner wall of a rough cable pipeline or the surface of a cable, and the rubber seal is gradually unfolded from a point to a line to a surface in contact with the pipeline wall or the surface of the cable, so that the sealing effect is better.
In order to prevent the excessive displacement of the left end cover into the cable duct hole, the diameter of the excircle of the left end cover is larger than the diameter of the cable duct hole. When the left end cover moves towards the cable pipeline hole, the annular step prevents the left end cover from moving towards the cable pipeline hole, and therefore excessive movement of the left end cover towards the cable pipeline hole is prevented.
Fig. 2 is the utility model discloses the semicircle integrated configuration schematic diagram of cable duct dead hole plugging device end cover, and fig. 3 is the utility model discloses cable duct dead hole plugging device rubber seal tubulose cylinder pipe wall breach schematic diagram. As can be seen from the figure, in order to facilitate the sleeving of the cable duct empty hole plugging device of the present invention on a cable, the left end cover and the right end cover are both semi-circular combined structures, i.e. two rigid semi-circular rings are combined into a complete circle; and a notch penetrating through the whole axial direction is arranged on the pipe wall of the rubber sealing tubular cylinder. During the suit, can be with two semicircles of end cover from cable both sides spiral-lock on the cable, rethread tie bolt fixes, can be with left end cover and right-hand member lid suit on the cable. The rubber sealing tubular column body can be broken off from the axial gap and is restored into the tubular column body by the elasticity of the rubber. By adopting the structure, construction can be more conveniently carried out.
Obviously, the utility model discloses cable duct dead hole plugging device's beneficial technological effect is that simple structure, rubber seal processing are easy and the shutoff effect is better.
