Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1 to 10 In this embodiment of the invention, a cable wall hole sealing device is composed of multiple sets of sealing components 10 connected end to end. Specifically, there are 4 sets of sealing components 10. As an optional implementation, the number of sealing components can also be set to 3, 5, 6, etc.

[0034] Multiple sets of sealing components 10 together form a central hole 101 for the cable to pass through. Each set of sealing components 10 is fixed as a whole by bolts. The sealing component 10 includes: a fire-resistant material that expands when exposed to high temperatures and a waterproof sealing gasket 15.

[0035] The sealing component 10 also includes: an upper pressure plate 11, an upper mounting base 13, an upper extrusion block 14, a lower extrusion block 16, a lower mounting base 17, and a lower pressure plate 19.

[0036] Each sealing component 10 has two fire-resistant material parts that expand when exposed to high temperatures, defined as the upper fire-resistant material part 12 and the lower fire-resistant material part 18. The bolts 20 that fix the sealing component 10 pass through the upper pressure plate 11, the upper fire-resistant material part 12, the upper mounting base 13, the upper compression block 14, the waterproof sealing gasket 15, the lower compression block 16, the lower mounting base 17, the lower fire-resistant material part 18, and the lower pressure plate 19 in sequence.

[0037] The waterproof sealing gasket 15 has an upper extrusion groove and a lower extrusion groove formed at both ends of the central hole 101 in the axial direction. One end of the upper extrusion block 14 is inserted into the upper extrusion groove, and the other end of the upper extrusion block 14 protrudes out of the groove and abuts against the upper mounting base 13. One end of the lower extrusion block 16 is inserted into the lower extrusion groove, and the other end of the lower extrusion block 16 protrudes out of the groove and abuts against the lower mounting base 17.

[0038] The upper mounting base 13 includes an integrally formed upper mounting plate 131 and an upper side wall plate 132. The upper mounting plate 131 extends from the upper side wall plate 132 in a direction away from the central hole 101. The upper fireproof material component 12 and the upper pressure plate 11 are both located on the side of the upper side wall plate 132 away from the central hole 101. In the axial direction of the central hole 101, the upper pressure plate 11 and the upper mounting plate 131 press the upper fireproof material component 12 from both sides.

[0039] The lower mounting base 17 includes an integrally formed lower mounting plate 171 and a lower side wall plate 172. The lower mounting plate 171 extends from the lower side wall plate 172 in a direction away from the central hole 101. The lower fireproof material component 18 and the lower pressure plate 19 are both located on the side of the lower side wall plate 172 away from the central hole 101. Axially downward from the central hole 101, the lower pressure plate 19 and the lower mounting plate 171 press the lower fireproof material component 18 from both sides.

[0040] In one specific implementation, the upper mounting base 13 and the lower mounting base 17 have the same structure. The upper extrusion block 14 and the lower extrusion block 16 have the same structure. The upper fireproof material component 12 and the lower fireproof material component 18 have the same structure.

[0041] In a preferred embodiment, the upper pressure plate 11 has an upper plate bolt hole through which the bolt 20 passes. The opening of the upper plate bolt hole protrudes towards the side of the upper fireproof material component 12, forming an upper annular boss. The upper fireproof material component 12 has an upper slot for inserting the upper annular boss for positioning. The lower pressure plate 19 has a lower plate bolt hole through which the bolt 20 passes. The opening of the lower plate bolt hole protrudes towards the side of the lower fireproof material component 18, forming a lower annular boss. The lower fireproof material component 18 has a lower slot for inserting the lower annular boss for positioning.

[0042] In a preferred embodiment, the bolt holes in the upper plate are countersunk holes. The head of the bolt 20 is recessed into the large hole of the bolt hole in the upper plate, while the shank of the bolt 20 passes through the small hole of the bolt hole in the upper plate.

[0043] In a preferred embodiment, the bolt hole in the lower plate is a countersunk hole. The nut 30, which mates with the bolt 20, is located in the larger hole of the bolt hole in the lower plate, and the shank of the bolt 20 passes through the smaller hole of the bolt hole in the lower plate. The larger hole of the bolt hole in the lower plate is a hexagonal hole that matches the shape of the nut 30.

[0044] In a preferred embodiment, the cross-section of the upper extrusion groove gradually decreases in the depth direction. Similarly, the cross-section of the lower extrusion groove gradually decreases in the depth direction.

[0045] Specifically, the side surface of the upper extrusion block 14 conforms to the shape of the groove wall of the upper extrusion groove. The side surface of the lower extrusion block 16 conforms to the shape of the groove wall of the lower extrusion groove. Specifically, the groove walls on both sides of the upper extrusion groove in the radial direction of the central hole 101 are inclined to the axial direction of the central hole 101. The groove walls on both sides of the lower extrusion groove in the radial direction of the central hole 101 are inclined to the axial direction of the central hole 101. The inner and outer wall surfaces of the upper and lower extrusion grooves are both part of a conical surface centered on the axis of the central hole 101. The shape of the extrusion blocks and extrusion grooves facilitates the extrusion deformation of the waterproof sealing gasket.

[0046] In a preferred embodiment, the upper pressure plate 11 protrudes radially from the outer surface of the upper fireproof material component 12. The lower pressure plate 19 protrudes radially from the outer surface of the lower fireproof material component 18. The upper pressure plate 11 and the lower pressure plate 19 achieve axial positioning of the wall hole, and improve the sealing effect by fitting against the end face of the wall hole.
