Abstract
The utility model discloses a plastic tube joint provided with copper inserts. The plastic tube joint comprises a first plastic tube joint body and a second plastic tube joint body, wherein a first extending part is arranged on the inner wall of the first plastic tube joint body, and a gap is reserved between the first extending part and an inner tooth copper insert; a second extending part is arranged on the inner wall of the second plastic tube joint body; and the first plastic tube joint body and the second plastic tube joint body are fixed together through screwing of the inner tooth copper insert and an outer tooth copper insert. According to the plastic tube joint, the extending parts are arranged on inner walls of the first plastic tube joint body and the second plastic tube joint body, so that direct contact between the copper inserts and water is effectively isolated, water pollution is prevented, drinking water safety is guaranteed, a reinforced sealing effect on water in a tube is realized, and the water leakage phenomenon is prevented. Compared with the prior art, the plastic tube joint is more environment-friendly, healthy, more compact in connection and better in sealing effect.
Description
[technical field]
The utility model relates to connection device technical field, particularly a kind of joint for plastic tube with copper insert.
[background technique]
At present, the safety of water quality is more and more subject to social concern and attention, but the use of joint for plastic tube in life is very general, and in a lot of processes that supply water, joint for plastic tube is absolutely necessary, in prior art, joint for plastic tube is made up of fittings body and copper insert, makes to produce on fittings body internal and external screw thread, thereby reach the object being connected and fixed by damascene copper inserts on fittings body.But copper insert is metallic material, water quality is there is to the problem of pollution, and tradition only also very easily produces in the mode of internal and external screw thread combination in copper insert the problem that interface leaks.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of joint for plastic tube with copper insert, can prevent that water pollutes and water leakage phenomenon, improves sealability.
For achieving the above object, the utility model proposes a kind of joint for plastic tube with copper insert, comprise the first joint for plastic tube body and the second joint for plastic tube body, one end of the first described joint for plastic tube body is inlaid with interior tooth copper insert, one end of the second joint for plastic tube body is inlaid with outer tooth copper insert, on the inwall of the first described joint for plastic tube body, be provided with the first extension part, between the first described extension part and interior tooth copper insert, be provided with gap, on the inwall of the second joint for plastic tube body, be provided with the second extension part, the first described joint for plastic tube body, the second joint for plastic tube body is by interior tooth copper insert, outer tooth copper insert is spirally connected and is fixed together, the top of the first described extension part is provided with first step, the top of the second extension part is provided with the second step corresponding with first step, between described first step and second step, sealing strip is set.
As preferably, in described gap, be provided with seal ring.
The beneficial effects of the utility model: on the inwall of the utility model by the first joint for plastic tube body and the second joint for plastic tube body, extension part is set, not only effectively having completely cut off copper insert contacts with the direct of water, prevent the pollution of water body, ensure the people's drinking water safety problem, and there is the effect of enhanced leaktightness for water body in pipe, prevent the phenomenon of leaking, compared with prior art, the utility model environmental protection more, health, connect closelyr, and sealing effect is better.
Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.
