Description
Technical field
The utility model relates to a kind of plastic tube, particularly relates to a kind of plastic pipe joint header structure.
Background technique
In today of plastics industry fast development, " to mould Dai Gang " is achieved in increasing industry, existing joint for plastic tube connecting means majority adopt respectively on two sections of plastic tubes direct machining screw realization be connected with a joggle, because plastics corrosion resistance is poor, easilier than metal to be oxidized, connect two sections of plastic tubes by current method shorter for working life, sealability also can be poor in addition, connects not tight.
Model utility content
Technical problem to be solved in the utility model is: the plastic pipe joint header structure providing a kind of long service life.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: plastic pipe joint header structure, comprise: left plastics pipeline section and right plastics pipeline section, a concentric left metallic sheath is had in one end arranged outside of described left plastics pipeline section, outside thread is had in the arranged outside of described left metallic sheath, a concentric right metallic sheath is provided with inside one end of described right plastics pipeline section, the inner side of described right metallic sheath is provided with the intermeshing internal thread with outside thread, integrative-structure is injection molded into respectively between described left plastics pipeline section and left metallic sheath and between right plastics pipeline section and right metallic sheath.
In order to solve the problems of the technologies described above better, the further technological scheme that the utility model adopts is: between described left plastics pipeline section and left metallic sheath, be provided with left cavity, described left plastics pipeline section is provided with the left gum-injecting port be connected with left cavity, right cavity is provided with between described right plastics pipeline section and right metallic sheath, described right plastics pipeline section is provided with the right gum-injecting port be connected with right cavity, in described left cavity and right cavity, is filled with sealer respectively.
In order to solve the problems of the technologies described above better, the further technological scheme that the utility model adopts is: between described left plastics pipeline section and right plastics pipeline section, be provided with sealing plug.
The utility model has the advantages that: above-mentioned plastic pipe joint header structure, in joint for plastic tube, metallic sheath is set, and joint for plastic tube and metallic sheath are injection molded into one, on metallic sheath, machining screw connects two sections of plastic tubes, substantially prolongs the working life of joint for plastic tube, between metallic sheath and plastic tube, adopt sealer to reinforce sealing simultaneously, ensure that the steadiness between metallic sheath and plastic tube, good seal performance, connects closely.
