That is, the upper end surface and the lower end surface of the box body 10 are both provided with outlets, and the lower end surface of the box body 10 is provided with the lower outlet 106, so that not only the downward threading effect through the lower outlet 106 can be realized on the basis of the upward threading through the outlet 100, but also the air exhaust and heat dissipation effects can be realized through the lower outlet 106. In addition, if water enters the box body 10 or the pipeline or the wire slot or impurities (such as concrete fragments) enter the box body in an unexpected situation, the water or the impurities can be discharged in time through the lower outlet 106, and the influence of the water or the impurities on the pipeline in the box body 10 is reduced as much as possible.

Further, in order to prevent the lower outlet 106 from being exposed for a long time, which affects the appearance and the usability, as shown in fig. 6, in this embodiment, the lower outlet 106 is provided with the sealing cover 108, and/or the filter screen 107, that is, the lower outlet 106 may be provided with only the sealing cover 108, only the filter screen 107, or both the sealing cover 108 and the filter screen 107, wherein the filter screen 107 may be disposed at a position where the lower outlet 106 is flush with the inner surface of the bottom of the box 10, or disposed in the lower outlet 106, or sleeved on the lower outlet 106.

Referring to fig. 1 to 7, in the present embodiment, the outlet 100 has a circular outlet shape. By providing the outlet 100 of the case 10 as a circular outlet, the mounting and dismounting between the case 10 and the cover 11 is facilitated, and the processing of the case 10 is facilitated. Referring to fig. 8, in another embodiment of the present invention, the outlet 100 is in the shape of a rectangular outlet. The cover 11 is also rectangular corresponding to the outlet 100, the cover 11 and the outlet 100 are hermetically connected through a fastener (such as a screw, a lock catch and the like), and the outlet 100 of the box body 10 is set to be a rectangular outlet, so that the area of the outlet 100 can be increased, and a worker can conveniently operate a pipeline in the line box 1 through the outlet 100. In other embodiments, the outlet may have other shapes, such as a polygonal shape, such as an oval shape, a triangular shape, etc., or an irregular shape, which is not limited in this respect and may be reasonably arranged according to actual needs.

In addition, since the box 10 is formed by integral molding, when demolding is performed, burrs or edges may exist at the boundary between the outlet 100 and the connection port 101 and the inner wall of the box 10, which may scratch a pipeline or a worker passing through the box 10, and in order to avoid scratching the pipeline or the worker, as shown in fig. 5 and 6, in this embodiment, a protection sleeve 13 is disposed in the box 10, the protection sleeve 13 is disposed at the outlet 100, and/or the connection port 101 is located at a port in the box 10. That is, the protecting sleeve 13 may be only disposed in the outlet 100, may be only disposed at the port of the connection port 101 in the box 10, or may be disposed in both the outlet 100 and the port of the connection port 101 in the box 10.
