For achieving the above object and other relevant objects, the invention provides a kind of easy mount type plastic water meter lid with magnet, include cage, upper cover, described cage, connecting portion is provided with between upper cover, described cage is ring-type, the outward flange of described cage is provided with lower magnet, cover on described and be provided with the upper magnet corresponding with described lower magnet, described upper magnet and described connecting portion are in the diametrically same of described upper cover, described upper magnet is embedded in described upper cover or is bonded in the upper surface of described upper cover, described lower magnet is embedded in described cage or is bonded in the lower surface of described cage, the lower inner edge of described cage is provided with at least two holding sections, described holding section is in circumferentially same, the shape of cross section of described holding section is the arc agreed with mutually with the lower inner edge of described cage, and described holding section is uniformly distributed in the lower inner edge of described cage, the lower end outside of described holding section is provided with card ear, and described card ear and described holding section are formed barb-like, angle≤90 ° that described card ear and described holding section are formed, and is provided with and is in same limiting section circumferentially with described holding section between described holding section.
Further, the outward flange of described upper cover is provided with turning cover part.
Preferably, described connecting portion, upper magnet, turning cover part are in the diametrically same of described upper cover.Described turning cover part, near upper magnet, is more conducive to opening and closing upper cover.
Further, the material of described plastic water meter lid is tygon or Polyvinylchloride.
As mentioned above, easy mount type plastic water meter lid with magnet of the present invention, there is following beneficial effect: the present invention is connected by connecting portion with cage with the upper cover of the easy mount type plastic water meter lid of magnet, material is tygon or Polyvinylchloride, can pass through mould one-shot forming, do not need repeatedly to process, production cost is low, speed of producing is fast, and production efficiency is high.During installation, the inner side card that holding section can be fastened on water meter cover by extruding is changed, and no longer needs first to take water meter cover apart, significantly improves installation rate, simple and convenient, improves installation effectiveness.The upper magnet of upper cover and the lower magnet phase adhesive of lower cover, can open rapidly and fasten water meter cover, easy to use, and can adapt to open and close frequently, long service life, dust-proof respond well with water proof.Limiting section, near the madial wall of water meter cover, plays position-limiting action to water meter cover, stabilized structure, can not loosen easily.
