Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example 1

Referring to fig. 1 to 5, the technical solution provided in this embodiment is: the utility model provides an outdoor heat shield who lays wire casing, the utility model discloses thermal-insulated effectual, simple structure, installation are convenient. The transversal rectangle of personally submitting of wire casing 100, wire casing 100 top inside wall has been seted up slot 110, wire casing apron 200 passes through slot 110 block is in wire casing 100 top, wire casing apron 200 is used for protecting the cable.

Referring to fig. 1 and 3, two heat shield installation frames 300 are further obliquely arranged on two sides of the top of the wire casing 100 through the fixing seat 210, the two heat shield installation frames 300 are hinged through the hinge 400, and the heat shield installation frames 300 can be folded through the hinge 400, so that the utility model discloses before not being installed and used, the transportation aspect is extremely convenient and do benefit to the storage.
