Description

Technical Field

[0001] The utility model relates to the field of cable fireproof plugging, and in particular to a modular cable fireproof plugging. Background Art

[0002] When laying cables, when cables need to be laid indoors such as service stations and substations or when cables are laid from indoors to outdoors, cables generally pass through the outer walls of the service stations or substations. Normally, holes need to be opened in the walls for the cables to pass through. After the cables pass through the walls, the remaining space needs to be sealed to prevent flames, smoke and harmful gases from spreading through cable channels or holes in the walls in the event of a fire, thereby avoiding safety hazards.

[0003] However, most modular cable fireproofing plugs currently have the following problems:

[0004] 1. The existing modular cable fireproof sealing, when sealing the cable, mostly seals the cable after the sealing material solidifies. In hot or humid weather, it is easy to cause the sealing material to crack or seal loosely. When replacing the cable later, the original sealing material must be removed, which is not only difficult to construct and has high construction requirements, but also easy to cause damage to the cable sheath, affecting the cable insulation performance and other problems, making it inconvenient to smoothly install and disassemble the cable.

[0005] 2. With the existing modular cable fireproof sealing, after sealing the cable, if the cable is pulled, it is easy to cause the sealing block to shift, and when the sealing block is misplaced, gaps are easily generated, which affects the sealing effect and is inconvenient to splice and align the used sealing blocks to avoid misalignment.

[0006] Therefore, we have made improvements to this and proposed a modular cable fireproof plugging system. Utility Model Content

[0013] As a preferred technical solution of the present application, the side end face of the push block is in contact with the inner side face of the mounting frame, and the cross-section of the push block and one side of the extrusion plate is inclined.

[0015] As a preferred technical solution of the present application, the second springs are symmetrically distributed on the left and right sides of the mounting plate, and the second springs correspond one-to-one with the first clamping blocks through the limiting plate.

[0016] As a preferred technical solution of the present application, a pull plate is fixedly connected to the limit plate, and a second clamping block is fixedly connected to the mounting plate, and the second clamping blocks are equidistantly distributed on the mounting plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the scheme of this application:

[0034] Example 2:

[0035] The solution in Example 1 is further introduced below in conjunction with a specific working method, as described below:

[0036] like Figure 2 As shown, as a preferred embodiment, on the basis of the above method, further, the peeling layer 5 is arranged in multiple layers and installed in the first installation module 3 and the second installation module 4, and the bidirectional threaded rod 7 is fixedly connected to the center part of one side of the turntable 8, which can ensure that when the turntable 8 is rotated, the bidirectional threaded rod 7 can be driven to operate smoothly.

[0038] like Figure 3 As shown, as a preferred embodiment, on the basis of the above method, further, two groups of first springs 11 are provided, the two groups of first springs 11 are symmetrically distributed on the extrusion plate 10, and each group of first springs 11 is equidistantly distributed on the extrusion plate 10, which can ensure that multiple first springs 11 can push the extrusion plate 10 to move smoothly.

[0039] like Figure 5 As shown, as a preferred embodiment, on the basis of the above method, further, the second springs 13 are symmetrically distributed on the left and right sides of the mounting plate 12, and the second springs 13 correspond one-to-one with the first clamping blocks 15 through the limit plates 14, which can ensure that the first clamping blocks 15 on both sides can smoothly engage and install the mounting plate 12.

[0041] Specifically, this modular cable fireproof plug is used in combination with: Figure 1-5 When the first mounting module 3 or the second mounting module 4 is to be spliced, the side end faces of the first mounting module 3 or the second mounting module 4 can be fitted together, and then the pulling plates 16 on both sides of the mounting plate 12 can be squeezed, and the pulling plates 16 drive the limiting plates 14 to move. At the same time, the limiting plates 14 can retract the first clamping block 15 into the mounting plate 12, and at the same time, the limiting plates 14 can squeeze the second spring 13, and then the mounting plate 12 and the second clamping block 17 are inserted into the first mounting module 3 or the second mounting module 4, and the pulling plates 16 on both sides are released. Under the push of the second spring 13, the limiting plates 14 and the first clamping block 15 are driven to reset.

At the same time, the holes opened on the first installation module 3 and the second installation module 4 are of different sizes, so cables of different sizes can be installed. Then the turntable 8 can be rotated to drive the bidirectional threaded rod 7 to operate. When the bidirectional threaded rod 7 drives the push blocks 9 on both sides to move outward at the same time, the extrusion plate 10 is not hindered by the push blocks 9 and moves inward at the same time under the pull of the first spring 11.

At the same time, the cable can be inserted into the first installation module 3 or the second installation module 4. The cable is thicker, which can reduce the internal stripping layer 5, and then drive the bidirectional threaded rod 7 to operate in the opposite direction. When the bidirectional threaded rod 7 rotates, it drives the push blocks 9 on both sides to move inward at the same time. At the same time, the push blocks 9 can push the extrusion plates 10 on both sides to move outward through the inclined surface. When the extrusion plates 10 move, they can squeeze the first spring 11, and the extrusion plates 10 can push the first mounting module 3 or the second mounting module 4 to squeeze, clamping and limiting the installed cable, and cooperating with the stripping layer 5 to achieve a sealing effect, and subsequently facilitating the disassembly and maintenance of the cable. After the cable is sealed, the mounting frame 1 can be installed in the use position. At the same time, the connecting frame 2 on the mounting frame 1 can be used for bolt connection and fixation to improve stability in use.
