Description

TECHNICAL FIELD

[0001] The utility model relates to sealing technical field, especially to a kind of integrated variable-diameter sealing module. BACKGROUND

[0002] In modern society, with the progress and development of society, the degree of electrification is continuously improved, and a large number of electrical equipment is needed in actual use, which greatly increases the demand for sealing of cables or pipelines. The existing cable or pipeline penetration sealing module has various forms, with the variable-diameter sealing module as the representative. By peeling off the peelable elastomer sheet of the module, the required cable or pipeline diameter size is achieved, and the sealing cable or pipeline is fixed by tightening and fastening.

[0003] Chinese patent publication No. CN205298841U discloses a variable-diameter sealing module, which mainly includes two elastic shell halves. A semicircular groove is provided in each elastic shell half. An elastomer sheet layer is covered on the groove, and the elastomer sheet layer is composed of multiple layers of peelable elastomer sheets. The upper and lower surfaces of each layer of peelable elastomer sheets are respectively provided with convex structures and concave structures. The width of the convex structure matches the width of the concave structure, and the height of the convex structure matches the depth of the concave structure. The convex structures and concave structures of adjacent two layers of peelable elastomer sheets are embeddedly connected. After the two elastic shell halves are closed and connected, a circular through hole is formed inside, which can pass through the cable or pipeline. The shell and the elastomer sheet layer of this technical solution are designed separately, which is time-consuming and laborious in production and assembly. Moreover, the sealing performance is relatively poor. UTILITY MODEL CONTENTS

[0004] In order to overcome the shortcomings of the existing technology, the utility model provides an integrated variable-diameter sealing module, which adopts an integrally formed flexible rubber sleeve and a variable-diameter core, solving the deficiencies of the prior art.

[0005] In order to solve the above problems, the utility model provides an integrated variable-diameter sealing module, which includes an integrally formed flexible rubber sleeve. The flexible rubber sleeve is provided with at least one through hole. Each through hole is provided with a variable-diameter core. The core includes a plurality of annular rubber layers with different inner diameters, which are nested layer by layer from small to large in inner diameter. The flexible rubber sleeve is provided with at least three radially through bolt holes in the circumferential direction. Each bolt hole is provided with a counterbore at one end. Each bolt hole is equipped with a fastening bolt, and each fastening bolt is equipped with a nut. The fastening bolt passes through the bolt hole, and the nut is placed in the counterbore and cooperates with the fastening bolt to lock.

[0006] The outer surface of each annular adhesive layer is provided with a double-sided adhesive layer, and two adjacent annular adhesive layers are bonded together by the double-sided adhesive layer.

[0007] The flexible rubber sleeve has a through hole and four bolt holes are provided around its circumference, and the four bolt holes are evenly distributed around the through hole.

[0008] The flexible rubber sleeve has four side lugs on its outer circumference, each of which has a through lug hole, and the four side lugs are evenly distributed along the outer circumference of the flexible rubber sleeve.

[0009] The flexible rubber sleeve is provided with four through holes, which are evenly distributed along the circumference of the flexible rubber sleeve; the flexible rubber sleeve is provided with four bolt holes along the circumference, which are also evenly distributed along the circumference of the flexible rubber sleeve.

[0010] Each of the bolt holes is located between the two through holes.

[0011] This utility model has the following advantages: The flexible rubber sleeve of this utility model is integrally molded. In use, it is only necessary to remove the annular rubber layer layer by layer from the inside to the outside of the variable diameter core according to the outer diameter of the cable, so that the cable can pass through. After the cable passes through the variable diameter core, the fastening bolt is tightened and the fastening bolt is tightened by the nut. When the flexible rubber sleeve is placed in the hole, the tightening of the fastening bolt causes the flexible rubber sleeve to expand inside and out. The external expansion of the flexible rubber sleeve abuts against the inner wall of the hole to achieve a seal, and the internal expansion of the flexible rubber sleeve can make the annular rubber layer abut against the cable to achieve a seal. The internal and external expansion of the flexible rubber sleeve achieves an overall seal, which is waterproof, sandproof, and prevents rodents and ants from entering the pipe hole.
