Description

Technical Field

[0001] The utility model relates to the technical field of wire boxes, in particular to a novel concrete modular building structural waterproof wire box. Background Art

[0002] As a new model of prefabricated building development, concrete modular box-type houses play an important role in rapid construction. At present, the conventional practice of the top of concrete modular box-type houses (hereinafter referred to as modules) is a 6cm thick composite board, and the pre-buried wire box of the composite board is 10cm thick beyond the board surface for the convenience of later pipeline connection. After the module is transported to the construction site, it is hoisted and spliced, and then the secondary pouring is completed after the pipeline connection is completed; the top 10cm wire box is exposed above the 6cm floor during the internal construction, storage and transportation of the finished product, and the secondary pouring of the floor slab. There is a gap between the wire box and the surrounding concrete, and then rainwater or construction water during the secondary construction will leak into the module from the gap. The leakage will cause the following adverse consequences: First, it will pollute and damage the finished surface of the house; second, water will enter the wire box, causing a short circuit after power is turned on, thereby damaging the lamps; all of the above require the module to be reworked and repaired, which is time-consuming and labor-intensive and increases costs.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-3As shown, the new concrete modular building structural waterproof wire box of this embodiment includes a box body 1, and a wing ring 2 is arranged at the end face of one side of the opening of the box body 1. The wing ring 2 protrudes from the end face and wall of the box body 1, which is equivalent to a water stop ring to prevent water from entering the box body 1. A threading hole 3 is opened at the side wall of the box body 1, and a locking mechanism 4 is arranged at the threading hole 3 in the inner cavity of the box body 1. The locking mechanism 4 includes a spring piece 401, a locking nut 402 and a flexible sleeve 403. The outer wall of the spring piece 401 is provided with a thread 5 used in conjunction with the locking nut 402. The locking mechanism 4 can fix the cable and cooperate with the flexible sleeve 403 to seal the connection between the cable and the box body 1. The flexible sleeve 403 is located at one end of the inner cavity of the threading hole 3 and is a trumpet-shaped structure.

[0022] Furthermore, the end surface of the wing ring 2 protrudes from the end surface of the box body 1, which is equivalent to a water stop ring to prevent water from entering the box body 1.

[0023] Furthermore, the wing ring 2 has a height of 1 CM and a width of 2 CM.

[0024] Furthermore, the outer wall of the flexible sleeve 403 is in contact with the inner wall of the spring sheet 401, and a limiting ring 6 is provided at one end of the flexible sleeve 403 away from the inner cavity of the box body 1. The limiting ring 6 can seal the connection between the wire harness and the box body 1.

[0025] Working principle: the wiring harness passes through the limit ring 6 and the flexible sleeve 403 in turn. After the wiring harness is located at one end of the inner cavity of the box body 1 with a suitable length reserved, the locking nut 402 is screwed. When the locking nut 402 rotates, it presses the flexible sleeve 403 through the spring 401 to clamp and fix the flexible sleeve 403. The deformation of the flexible sleeve 403 clamps and seals the wiring harness.
