Embodiment 1

[0041] Embodiment 1: One-piece cable hole plugging device

[0042] Such as Figure 1-Figure 2 As shown, the preferred embodiment 1 of the present invention discloses an integrally formed cable hole blocker, which includes a first hard layer 1, a soft rubber layer 2 and a second hard layer 3, the soft rubber layer and the two The hard layer is integrally formed by insert molding process. The hard layer is made of PS material, and the soft layer is made of PE material.

[0043] The first hard layer 1, the soft rubber layer 2 and the second hard layer 3 are respectively provided with a cable hole 11, a cable hole 21 and a cable hole 31 whose axes coincide; 4 threaded holes 12, 4 light holes 22 are evenly distributed around the cable hole 21, 4 light holes 32 are evenly distributed around the cable hole 31; the axes of the threaded holes 12, the light holes 22 and the light holes 32 coincide; The cable hole 11, the cable hole 21 and the cable hole 31 form the cable hole of the ...

Embodiment 2

[0047] Example 2: Cable Hole Closure Device with Split Structure

[0048] Figure 4 It is a schematic cross-sectional view of the split occluder involved in the preferred embodiment 2 of the present invention, and the cut position is as follows: figure 1 shown. read Figure 4 It can be seen that the occluder disclosed in Example 2 includes a first hard layer 10, a soft rubber layer 20, and a second hard layer 30; the soft rubber layer and the two hard layers are a separate structure.

[0049] read Figure 4 It can be seen that the central positions of the first hard layer 10, the soft rubber layer 20 and the second hard layer 30 are respectively provided with a cable hole 101, a cable hole 201 and a cable hole 301, and the axes of the three cable holes coincide. Form the cable hole of the cable hole blocker in this embodiment. Four threaded holes 102 are arranged on the first hard layer 10, and the four threaded holes 102 are evenly distributed around the axis of the firs...

Embodiment 3

[0055] Embodiment 3: The soft rubber layer is a cable hole plugging device with a fan-shaped sheet structure

[0056] The basic components, connections, functions and principles of the components in Embodiment 3 of the present invention are exactly the same as in Embodiment 2, the difference is that the soft glue layer 20' in Embodiment 3 is Figure 6 The fan sheet structure shown in , when the fan sheet structure is enclosed, can form the conical structure in embodiment 2, and an opening is formed at the overlapping seam; the soft rubber layer and the two hard layers 10' and 30' The connection and fixing relationship between them is the same as the various structures and cooperation relationships disclosed in Embodiment 2, and will not be repeated here. The soft rubber layer is processed into a fan-shaped sheet structure, which is convenient for storage, packaging and transportation. In addition, as an improvement, snap joints can also be provided at overlapping joints of th...

Abstract

The invention discloses a plugging device for a cable hole. The whole plugging device is in the shape of a circular truncated cone. A cable orifice is formed in the center of the circular truncated cone. The plugging device is characterized in that the circular-truncated-cone-shaped plugging device for the cable hole comprises a first hard layer, a soft rubber layer and a second hard layer. The first hard layer is located on the upper surface of the plugging device for the hole. The second hard layer is located on the lower surface of the plugging device for the hole. The soft rubber layer is arranged between the first hard layer and the second hard layer in a clamped mode. At least one of the first hard layer and the second hard layer is provided with threaded holes, and the other hard layer is provided with unthreaded holes or threaded holes. The corresponding positions of the soft rubber layer are also provided with unthreaded holes or threaded holes or a cavity. When construction is conducted, the plugging device is pressed into the cable hole firstly, and then the soft rubber layer is prompted to deform due to squeezing of a screw, so that the plugging effect is improved. The plugging device has the characteristics of being simple in operation, high in construction efficiency, high in practicability, easy to disassemble, good in the plugging effect and the like.

Description

technical field [0001] The invention belongs to the technical field of cable connection, and in particular relates to a cable hole blocking device. Background technique [0002] When the power cable passes through the wall and the electrical control box, the holes on the wall and the electrical control box need to be sealed to prevent dust, animals from entering the control box, the control room or the flame spreading through the hole in case of fire. According to the relevant national regulations, the following construction situations need to seal the cable hole: [0003] 1. All transformer rooms, protection rooms, cable interlayers, electrical cabinets (panels), AC and DC cabinets ( panel) cable holes and holes in the control panel, instrument panel, protection panel, etc. [0004] 2. Shafts and cable entrances entering the oil area. [0005] 3. Outdoor terminal box, power box, control box and other cable entry places. [0006] 4. The indoor cable trench cable passes t...
