Description

Technical Field

[0001] The present invention relates to the technical field of pipeline fittings, and particularly to a novel flexible cable sleeve plugging device. Background Art

[0002] With the development of society, more and more power cables enter buildings from underground. After the cable sleeves are laid during construction, the sleeves through which the cables have passed or the sleeves reserved without passing cables need to be plugged. Therefore, using a cable sleeve plugging device for plugging has become an important link in power construction.

[0003] A sleeve plugging device is a sealing device arranged inside a cable sleeve, which can prevent sewage, sediment, and animals from entering the pipeline and damaging the cables. It is generally made of rubber. When the rubber is longitudinally extruded, it expands outwards. When there is no cable passing through, it fills the sleeve, and when there is a cable passing through, it fills the gap between the sleeve and the cable to achieve the sealing of the pipeline. Summary of the Invention

[0004] The purpose of the present invention is to provide a flexible cable sleeve plugging device with good plugging effect and easy operation. It has a simple structure and is convenient to use.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] A flexible cable sleeve plugging device includes a cylinder made of rubber material. The cylinder is divided into two upper and lower parts. The lower part consists of two left and right semi-circles, and the two semi-circles can form a circular seal. The seal has circular ring-shaped grooves with different diameters from the center of the circle to the diameter direction of the cylinder. The upper part has circular ring-shaped protrusions corresponding to the lower part. Two semi-circular upper pressing plates are arranged at the upper end of the cylinder, and two semi-circular lower pressing plates are arranged at the lower end of the cylinder. Through holes corresponding to each other longitudinally are arranged on the upper and lower pressing plates and the cylinder. Several screw rods sequentially pass through the through holes of the upper pressing plate, the cylinder, and the lower pressing plate from top to bottom. The nuts of the screw rods are placed at the upper end of the plugging device, and nuts are sleeved on the ends of the screw rods passing through the lower pressing plate.

[0007] Further, there is a cylindrical plug made of rubber material in the center of the upper part of the cylinder. The cylindrical plug has rings with different sizes from the center of the axis of the cylinder outwards. The gaps between the rings correspond to the positions of the protrusions in the lower part of the cylinder.

[0008] Furthermore, in the flexible cable sleeve plugging device, the nuts of the screw rods are placed on the through holes of the upper pressing plate, and the through holes on the upper pressing plate, the cylinder, and the lower pressing plate are conformable to the outer shape of the nuts.

[0009] Furthermore, the flexible cable sleeve plugging device is characterized in that the upper and lower pressing plates are composed of two semi-circular rings, and there are holes corresponding to the through holes on the cylinder in the ring.

[0010] The beneficial effects of the present invention are:

[0011] For the flexible cable sleeve plugging device of the present invention, the cylinder between the upper and lower pressing plates is tightened and extruded by the screw and nut, so that the cylinder squeezes the cable inward and the sleeve outward. Since the cylinder is made of flexible material and expands more when encountering water, the plugging effect is better and it is not easy to loosen.

[0012] Other advantages, objectives and features of the present invention will be described to some extent in the subsequent description, and to some extent, will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present invention. The objectives and other advantages of the present invention can be achieved and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings, where:

[0014] Figure 1 is a perspective view of the present invention;

[0015] Figure 2 is a front view cross-sectional view of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following will refer to the drawings to describe the preferred embodiments of the present invention in detail. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the protection scope of the present invention.

[0017] As Figure 1-2 shown, a flexible cable sleeve plugging device includes a cylinder 1 made of rubber material. An opening 2 is provided on one side of the cylinder 1 along its height direction. The diameter of the outer wall of the cylinder 1 gradually increases from both ends to the middle, and the diameter of the inner wall of the cylinder 3 gradually decreases from both ends to the middle. An upper pressing plate 4 is provided at the upper end of the cylinder 1, and a lower pressing plate 5 is provided at the lower end of the cylinder 1. Through holes corresponding to each other longitudinally are provided on the upper and lower pressing plates and the cylinder 1. A screw 6 with a nut at the lower end passes through the through holes of the lower pressing plate 5, the cylinder 1, and the upper pressing plate 4 from bottom to top. The nut of the screw 6 is placed at the lower end of the plugging device, and a nut is sleeved on the end of the screw 6 passing through the upper pressing plate 4.

[0018] When it is necessary to seal the cable passing through the casing, cut out the cylinders 1 and 3 according to the cable diameter, pass the cable through the casing plug through the cylinders, then put the plug with the cable into the casing. After putting it in, tighten the nut on the screw 6 on the upper pressing plate 4. At this time, the upper and lower pressing plates squeeze the rubber cylinder in the middle, causing it to expand inward and outward, tightly adhering to the cable and the casing, forming a sealed state, effectively preventing sewage, sediment, and animals from entering the pipeline.

[0019] When used for the temporary sealing of the cable casing, directly select a flexible cable plug of the appropriate size and put it into the casing. After putting it in, tighten the nut on the screw 6 on the upper pressing plate 4. At this time, the upper and lower pressing plates squeeze the rubber cylinder in the middle, causing it to expand inward and outward, tightly adhering to the casing, forming a sealed state.

[0020] The nut of the screw 6 is placed in the through hole of the lower pressing plate 5. The through hole on the lower pressing plate 5 conforms to the outer shape of the nut, that is, the through hole of the lower pressing plate 5 is inverted T-shaped in the longitudinal section. The nut of the screw 6 is restricted by the through hole on the lower pressing plate 5, achieving the purpose of preventing the screw 6 from rotating.

[0021] The upper and lower pressing plates are annularly arranged, aiming to make the cylinder evenly stressed and produce uniform deformation.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the present technical solution, and they should all be covered within the scope of the claims of the present invention.
