O type ring, for rubber being the thin ring of material, its cross section is circular, stressed deformability in order to infiltration or the leakage of blocking fluid, has the height water-proof function.

Lower base is the ring bodies of a hollow, the rough external diameter that equals quartz outer tube in inner aperture; Lower base inside is provided with internal thread, as the usefulness that engages with the following external screw thread of upper pedestal; Interior anchor ring is then as the usefulness of O type loop contacts bearing surface.

Quartz outer tube is the quartz glass tube of a upper end open, mainly ties up to the protection quartz inner pipe, and the quartz outer tube outside then directly contacts with water.

The utility model compared with prior art has remarkable advantages and beneficial effect:

The utility model ultra-violet lamp tubular construction; owing to adopted; the lower base design; to cooperate the device of O type ring; utilize its pressing-type sealing effect; improved waterproof performance; it is more convenient that fluorescent tube is changed; filament was coated on quartz inner pipe under wherein the last filament of quartz burner reached; be inserted in quartz outer tube again; cooperate the sealing of O type ring to block effect, form duplicate protection, and change adopt O type ring and on; lower base cooperates the sealing means of packing; can make O type ring seal between pedestal and quartz outer tube fully between the crack; effectively block the water body seepage, improved the traditional UV germicidal tube and utilized the relatively poor problem of rubber watertightness that adhesive agent causes, improve the useful life of quartz burner; and easy-to-mount separate type design can be saved preventive maintenance time.
