Description

Technical Field

[0001] This utility model relates to the technical field of explosion-proof cable joint boxes, and in particular to explosion-proof stainless steel cable joint boxes. Background Technology

[0002] With the continuous progress of society, urban development planning, and the increasing automation of industry, the demand for electricity is also constantly increasing. Long-distance, large-scale power transmission often requires the laying of a large number of cables. Power supply units or construction units often use explosion-proof cable joint boxes with fireproof, waterproof, and explosion-proof functions to provide all-round protection for cable joints. The cable joint is protected and fastened inside the explosion-proof shell. The main function of the explosion-proof cable joint box is to protect the cable from being crushed. Another function is insulation. The existing explosion-proof box has an internal cavity design that easily accumulates flammable gas and does not have a pressure relief channel. This can lead to the shell bursting due to a sudden increase in internal pressure. At the same time, the cable does not have a restraining structure inside the explosion-proof box. When it is hit or vibrated, the cable may hit the inner wall of the explosion-proof box and be damaged. To solve the above problems, a stainless steel cable joint explosion-proof box is proposed. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides an explosion-proof stainless steel cable connector box, characterized by comprising an upper box body, a lower box body, a wire hole, a mounting block, a screw, a support bracket, a pressure relief port, an injection port, a sealing cap, and a tightening bolt. The lower box body is mounted on the upper box body, the wire hole is provided on the upper box body, the mounting block is provided on the upper box body, the screw is provided on the mounting block, the support bracket is provided on the screw, the pressure relief port is provided on the upper box body, the injection port is provided on the upper box body, the sealing cap is provided on the injection port, and the tightening bolt is provided on the upper box body.

[0004] Furthermore, the upper box and the lower box are connected by a pivot and fixed by tightening bolts. Both sides of the upper box are provided with wire holes, and both sides of the lower box are also provided with wire holes. The wire holes of the upper box and the lower box are combined to form a circular channel.

[0005] An installation block is fixedly installed on the inner wall of the upper box. There are several installation blocks. A screw is threadedly connected to the installation block. A support frame is installed at the other end of the screw via a bearing. The upper surface of the support frame is an arc-shaped surface.

[0006] Furthermore, the inner wall of the lower box is also provided with mounting blocks, which correspond vertically to the mounting blocks of the upper box.

[0007] Furthermore, a pressure relief port is provided on the outer wall of the upper box, the pressure relief port is a serrated pressure relief area, and an injection port is provided on the outer wall of the upper box, the injection port leads to the inner wall of the upper box, and a sealing cap is provided on the injection port by bolts.

[0008] The beneficial effects of this utility model are:

[0009] This invention involves placing the cable to be used through a through-hole onto the support bracket of the lower housing. Rotating the screws in the mounting blocks of the upper and lower housings adjusts the height of the support brackets. Closing the upper housing allows the support brackets of the upper and lower housings to clamp the cable, preventing it from shaking. Tightening the bolts secures the upper and lower housings. At this point, the cable passing through the through-holes in the upper and lower housings forms a circular channel, which is then sealed with sealing strips. During use, if the pressure inside the cavities of the upper and lower housings becomes excessive, the pressure relief area of ​​the scored pressure relief zone ruptures, releasing the internal pressure. When it is necessary to inject adhesive into the housing, the sealing cap is opened, and adhesive is injected into the housing through the injection port. The pressure relief channel prevents the housing from bursting due to a sudden increase in internal pressure. Additionally, a limiting structure inside the explosion-proof box prevents the cable from hitting the inner wall of the explosion-proof box during impacts or vibrations, reducing damage.
