opening and closing device of plastic insulation materials used in the power line component

摘要

this design is a plastic of the thermal insulation material used for the opening and closing device for opening and closing the show.;this design is a plastic housing (1) of thermal insulation material (5) in order to switch the switching line (11) or the material for the support tube (4) is installed in the power line (11) of the power line, the induction of the component (12),;the elastic steel wire with the tire wheel or a two wheel twist the rotating ring (19) that rotate in the ring (19) on both sides of the valley, an opening (16) has a hook with a hook (16a) (13) of the roller (15). the roller holder (14) to be formed in the above ring (13) of the rotating ring (19) of the screw head (18) with screws (17) with the roller holder (14) on the top part of the screw hole in the center of the form (23) and a screw (17), and the connection of the support roller bracket, is (14) for the switch (11), and are free of guide action is also more features.;the original design of the power line or the plastic material and the roller holder is to rotate the hook screw combination on the 360 is free to move, the power line installation of thermal insulation material on the roller and the side of the clip, clip fixed to a switching position. even with power line. but this is not a waste of insulation materials to facilitate, can be effective.
