Fig. 2 is the structural schematic diagram of insulation sleeve provided by the embodiments of the present application;
Fig. 3 is the top view of wall bushing provided by the embodiments of the present application.
It illustrates:
Wherein, 1- insulation sleeve;2- conducting rod;3- end cap;11- insulated mounting plate;12- outdoor insulation set;It insulate in the room 13- Set;111- mounting hole;Full skirt outside the room 121-;Full skirt in the room 131-.
Specific embodiment
In order to make those skilled in the art better understand the technical solutions in the application, below in conjunction with attached drawing, it is right Technical solution in the embodiment of the present application is clearly and completely described.
Referring to Fig. 1, the embodiment of the present application provides a kind of wall bushing, comprising: insulation sleeve 1, through the insulation sleeve 1 End cap 3 on 2 both ends of conducting rod 2 and the conducting rod;The insulation sleeve 1 includes insulated mounting plate 11,12 and of outdoor insulation set Indoor insulation sleeve 13, the outdoor insulation set 12 and indoor 13 face of insulation sleeve are set to the two of the insulated mounting plate 11 Side;Outdoor full skirt 121 on the outdoor insulation set 12 is the alternate setting of size, the indoor full skirt on the interior insulation sleeve 13 131 be identical size.Insulation sleeve 1 in the application is an integral structure, when installation, the mounting hole being aligned on wall, by room Interior insulation set 13 is fixed on wall towards indoor placement by the outdoor placement of 12 direction of outdoor insulation set, then by insulated mounting plate 11, After insulated mounting plate 11 is fixed, end cap 3 is installed on conducting rod 2, and is fixed with bayonet lock.
Optionally, wall bushing further includes metal plate, and the metal plate is located between the insulated mounting plate 11 and wall. Meanwhile hole compatible with outdoor insulation set 12 or indoor insulation sleeve 13 is additionally provided on metal plate, it is extended there through convenient for it, metal Plate to be mounted so as to more fasten between insulated mounting plate 11 and wall, not easily to fall off.
