Description
Technical field
The utility model belongs to electric transmission line installation accessories technical field, particularly a kind of connection screw protecting cover.
Background technique
Fastening screw is that the most general connector element is used in electric power system, and the overwhelming majority is installed in the wild environment, though at its surperficial many platings resin layer is arranged; But owing to corroded by sleet, dust and corrosive gas for a long time; The damage that gets rusty easily, cause working life short, overhaul of the equipments dismounting difficulty is big, influences the overhaul of the equipments operating efficiency; Cause the maintenance power off time long, influence transmission operation efficient.
The model utility content
The purpose of the utility model is to provide a kind of can avoid connecting the screw corrosion effectively, prolongs screw working life, easy to use, is convenient to connect the connection screw protecting cover of screw maintenance dismounting.
The technological scheme that purpose adopted that realizes the utility model is: a kind of connection screw protecting cover has one and is used for the soft sleeve pipe that suit connects screw, an end welded seal of soft sleeve pipe.
Said soft sleeve pipe adopts plastic cement or plastic part.
The connection screw protecting cover of the utility model; Can prevent the erosion of sleet, dust and corrosive gas effectively; Prolong the working life that connects screw, conveniently connect the maintenance dismounting of screw, if on the connection screw, smear anti-corrosive grease earlier; And then carry out the suit of this protecting cover, then rust-proof effect is better.This protecting cover is simple in structure, and is easy to use, cheap.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to Fig. 1, the connection screw protecting cover of the utility model has one and is used for the soft sleeve pipe 1 that suit connects screw 2, an end welded seal of soft sleeve pipe 1.Said soft sleeve pipe 1 adopts plastic cement or plastic part, is convenient to connecting suit on the screw 2, and is connected firmly difficult drop-off.Label 3 is by connector element among the figure.When this protecting cover uses, can be sleeved on connection screw 2 and the nut, can prevent the erosion of sleet, dust and corrosive gas effectively; If on connection screw 2, smear anti-corrosive grease earlier; And then carry out the suit of this protecting cover, then rust-proof effect is better, the dismounting during easy access.
