Plastic Pipe ClampA plastic pipe clamp locking device comprises a plastic pipe clamp and a locking device body. The plastic pipe clamp locking device is characterized in that the locking device body is arranged on a fastened metal pressure plate at the top of the plastic pipe clamp, two ends of the locking device body are provided with two bolt holes, and each bolt hole is provided with three toothed block pieces outside the same; the bolt holes of the locking device body are identical to metal pressure plate bolt holes in the top of the plastic pipe clamp; the locking device body is made of Q235-A material. Compared to the prior art, the plastic pipe clamp locking device has the advantages of being simple in structure, low in cost and convenient to demount and mount, and a good locking function is achieved; further, the situations that the fastening bolts loosen and a clamp pressure cover falls of can be effectively prevented; malignant accidents such as leakage and breakage when a medium pipeline vibrates can be prevented.The plastic pipe clamp locking device, the structure is simple, low cost, easy accessibility, have played a very good anti-loosening effect. Can effectively avoid the fastening bolts loose hose clamp gland off phenomenon. Prevent media leaks pipe vibration, breakage and other accidents.The feature:High temperature resistance.Self lubrication.Wear resistance.Flame retardant properties.The application:1.transmission system in areas of industrial dical device,automotive,office equipment,household 3.appliances,digital electronic,toy etc.
