The stripping attachment includes a main tie and at least three subties;
The main tie is the threaded cylindrical bar in outer surface;Described main tie one end is the oblate structure flattened, another Hold as the threaded post in big footpath;The main tie is used cooperatively with the centre bore;
Described subtie is the threaded cylindrical bar in outer surface;One end of the subtie is the oblate structure flattened; The subtie lateral opening is used cooperatively with described;The number of subtie is corresponding with the number of supporting leg;
The stripping attachment includes fixing nut, and fixing nut is step structure, and its top is square structure, and here is round Column construction, its axial center are provided with central passage;
Multiple stopper slots are provided with the cylindrical structural of the fixing nut, each stopper slot is tied along cylindrical nut cylinder The excircle of structure is evenly arranged;
The stripping attachment includes a crank, and the crank is stepped cylindrical structural, its miner diameter end with it is described spacing Groove is used cooperatively.
Preferably:Fixing nut includes two kinds of specifications, the fixing nuts of described two specifications respectively with main tie It is used cooperatively with subtie.
Preferably:The miner diameter end of stopper slot and crank is the circular configuration to cooperate;Or stopper slot and shake Miner diameter end for cooperate polygonized structure.
Preferably:The depth of stopper slot is the 1/2 of fixing nut radius.
Preferably:The external diameter of circle is more than RO film barrel diameters where the supporting leg outward flange of star shaped supporting.
Preferably:When in use, it is star shaped supporting is smooth in RO film cylinders one end, respectively by main tie and secondary drawing Then bar inserts the end of main tie and subtie corresponding on RO film end caps through the centre bore on star shaped supporting and lateral opening In screw hole and tighten, each self-corresponding fixing nut is screwed on pull bar and tightened, is finally uniformly shaken successively with crank Fixing nut, RO film end caps are smoothly pulled out by the fastening force of fixing nut and pull bar.
Compared with prior art, this stripping attachment disclosed in the utility model, it is mainly used in flourish extra large reverse osmosis (RO) film The dismounting of end cap, it is a kind of multiple spot stress " manual thruster ", will using a plurality of bolt of long stem and the fastening force of nut screw thread RO film end caps equably pull out from cylinder, and multiple spot uniform force, pulling force are big, safe and reliable, dismounting is quick, easy to use, system It is low to make cost, removal efficiency is high.
