Embodiment Construction

[0017] As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a sealing device for sealing holes is mainly composed of an auxiliary sealing connection device 1, an elastic sealing member 2 and a compression device 3, wherein: there will be a sealing member 11 The auxiliary sealing connection device 1 covers the hole 12 that needs to be sealed and is connected with the main structure 13. Its structure is similar to a flange and is provided with a mounting hole 14; an elastic seal 2 is placed in the mounting hole 14, Its shape is adapted to the shape of the installation hole 14 of the auxiliary sealing connection device 1, and its installation cross-sectional area is larger than the hole cross-sectional area of ​​the installation hole 14 of the auxiliary sealing connection device 1. The elastic sealing member 2 is provided with an extension through the hole 12. The extension holes 22 corresponding to the number of pieces 21, the diameter of the holes should be slightly smaller th...

Abstract

A kind of stealing device of a closed hole which is mainly insisted of a secondary tight coupling device (1), an elastic sealing component (2), and a hold-down gear. Make the secondary tight coupling device with a sealing component (11) covering the holes (12) which need to be sealed at the same time connecting with the major structure (13). Put the elastic sealing component (2) into the mounting hole (14) and implant the sealing baffle plates (31) at the up-and-down of mounting hole and one of them is installed at the inner of if and another is installed at the edge of it also there is a hold-down bolt (32) through the center of it. It can implement the sealing affection and get the bearing of self allocation by hold-down bolt (32) and the sealing baffle plate (31) pressure to the elastic sealing component. The invention has high reliability, significant sealing affection, simple structure, low manufacturing cost and it is convenience to use, maintenance and repair.

Description

technical field [0001] The invention relates to a sealing device for an extension piece passing through a hole, especially a sealing structure device for an electric cable or an optical cable, an optical fiber or an electric wire, a hard tube, a hose or a tubular object passing through a hole. Background technique [0002] In various industrial application fields, it is often involved in the sealing of cables (such as cables, optical cables, ropes) or pipes through through holes. It is generally used in the fields of sealing low pressure or low reliability requirements, and often uses glue or rubber blocking blocks. For sealing, there is also a sealing form using rubber pads and nuts. The use of glue sealing can meet the requirements of multi-cable sealing, but the disadvantage is that the installation process is more complicated, and it is inconvenient to maintain after the cable has a problem; the use of rubber block can only meet the low-pressure sealing requirements; the...
