Embodiment Construction

[0037] The installation of waterproof trunking is generally to fix the wire boxes on the ground in sections first, and then connect the joints of adjacent wire boxes with sealed connectors. In order to improve the sealing of the joints of waterproof trunking wire boxes, the applicant has The sealing connector of the trunking is improved to improve the overall sealing of the waterproof trunking.

[0038] The waterproof trunking of the present application includes at least two connected wire boxes 6 , and the joints between adjacent wire boxes 6 are connected and sealed by a sealing connector 100 .

[0039] Preferably, the wire box 6 is one of straight-through, bent-through, three-way and four-way, such as Figure 11 , 12 As shown, this application gives an example of two bend connections.

[0040] The sealed connector 100 of the present application, such as Figure 9 , 10 As shown, two connecting pieces are included, and the two connecting pieces are assembled into a sealed...

Abstract

The invention relates to the technical field of waterproof wire ducts, and discloses a connecting piece, a sealing connector and a waterproof wire duct, the connecting piece comprises a transverse piece and a side piece, one end of the transverse piece is vertically connected with one end of the side piece, the other end of the transverse piece is provided with at least one connecting part A, andthe other end of the side piece is provided with at least one connecting part B; a sealing gasket A and a sealing gasket B are laid on the inner wall of the transverse piece and the inner wall of theside piece respectively, the connecting face of the connecting part B is an inclined face, a matching piece is further included, the matching piece is provided with a matching face connected with theconnecting face of the connecting part B in a matched mode, and the matching piece, the connecting part A and the connecting part B of the other connecting piece are connected through connecting pieces. The connecting surface of the connecting part B is an inclined surface, and when the connecting part B is locked through the connecting piece, the matching piece can apply transverse and longitudinal forces to the side pieces, so that the two connecting pieces are connected more tightly, and the sealing performance of the sealing connector is enhanced.

Description

technical field [0001] The invention relates to the technical field of waterproof wire grooves, in particular to a connecting piece, a sealed connector and a waterproof wire groove. Background technique [0002] At present, many cities in China are developing rail transit, especially the construction of subways. Since the subway is built in the tens of meters below the surface, groundwater will seep into the infrastructure of the subway platform. At present, the marble or tiles on the floor of the subway platform are dry-pasted, and the dry-pasted gray and yellow sand account for the vast majority. , the internal crispness is bound to be permeable, and these permeable water contains strong alkaline components brought by the building structure concrete, which is very corrosive. After the laying of ground pipelines for a considerable part of the AFC system of subways, the strong and weak current pipelines are all infiltrated by groundwater, especially in coastal cities along ...
