Description

The reliable pipe joint of a kind of connection

Technical field

This utility model relates to pipe fitting field, is specifically related to the reliable pipe joint of a kind of connection。

Background technology

In the connection of pipeline, particularly flexible pipe and the connection of metal pipe mouth, be often required for just completing both connections by means of pipe joint。Existing union joint is of a great variety, but generally there are following defect: structure is complicated, the time-consuming effort of installing/dismounting, and connection sealing is inadequate, it is easy to cause leakage。

Utility model content

In sum, for overcoming the deficiencies in the prior art, technical problem to be solved in the utility model is to provide the reliable pipe joint of a kind of connection。

The technical scheme that this utility model solves above-mentioned technical problem is as follows: the reliable pipe joint of a kind of connection, this joint is used for flexible pipe fixed cover in metal pipe mouth, including fixing cylinder and bail wire, it is enclosed within outside described metal pipe mouth described fixing cylinder is dismountable, the external diameter of described fixing cylinder is more than the external diameter of described bail wire, and described fixing cylinder connects described bail wire by multiple connection straps, described fixing cylinder, described bail wire and described connection strap form one and have the round table-like of tapering；

Described bail wire includes semi-circular tube and half-round bar, the two ends of described half-round bar extend into inside it from the opening of described semi-circular tube respectively, the elastic component coupled together at described half-round bar two ends it is additionally provided with in described semi-circular tube, and described elastic component flexible can so that described semi-circular tube and described half-round bar relative motion, such that it is able to change the internal diameter of described bail wire by hose clamp outside described metal pipe mouth。

Further, described elastic component is spring。

Further, described fixing cylinder is threadeded with described metal pipe mouth。

Further, described connection strap welds with described fixing cylinder and described bail wire respectively。

The beneficial effects of the utility model are: the one that this utility model provides connects reliable pipe joint, simple in construction, and energy is installing/dismounting quickly, and connection sealing is good, it is not easy to cause leakage。

Fig. 2 is front view of the present utility model；

Fig. 3 is left view of the present utility model。

In accompanying drawing, the list of parts representated by each label is as follows:

1, flexible pipe, 2, metal pipe mouth, 3, fixing cylinder, 4, bail wire, 5, connection strap, 6, semi-circular tube, 7, half-round bar, 8, elastic component。

Detailed description of the invention

Below in conjunction with accompanying drawing, principle of the present utility model and feature being described, example is served only for explaining this utility model, is not intended to limit scope of the present utility model。

Connecting reliable pipe joint as it is shown in figure 1, a kind of, this joint is used for flexible pipe 1 fixed cover in metal pipe mouth 2。As shown in Figures 2 and 3, including fixing cylinder 3 and bail wire 4, it is enclosed within outside described metal pipe mouth 2 described fixing cylinder 3 is dismountable, concrete: described fixing cylinder 3 is threadeded with described metal pipe mouth 2。The external diameter of described fixing cylinder 3 is more than the external diameter of described bail wire 4, and described fixing cylinder 3 connects described bail wire 4 by multiple connection straps 5, described fixing cylinder 3, described bail wire 4 and described connection strap 5 form one and have the round table-like of tapering, it is preferred that: described connection strap 5 welds with described fixing cylinder 3 and described bail wire 4 respectively。

Described bail wire 4 includes semi-circular tube 6 and half-round bar 7, the two ends of described half-round bar 6 extend into inside it from the opening of described semi-circular tube 7 respectively, the elastic component 8 coupled together at described half-round bar 7 two ends it is additionally provided with in described semi-circular tube 7, it is preferred that: described elastic component 8 is spring。And described elastic component 8 flexible can so that described semi-circular tube 6 and described half-round bar 7 relative motion, such that it is able to flexible pipe 1 is stuck in outside described metal pipe mouth 2 by the internal diameter changing described bail wire 4。

Needing, by flexible pipe 1 fixed cover when metal pipe mouth 2, to be enclosed within outside metal pipe mouth 2 by the fixing cylinder 3 of union joint, do not tighten fixing cylinder 3, now bail wire 4 is in the front of metal pipe mouth 2, then is enclosed within advance outside metal pipe mouth 2 through bail wire 4 by flexible pipe 1。After described work completes, being tightened cylinder 3 along metal tube, fixing cylinder 3 moves along metal tube, thus driving bail wire 4 to travel forward。A bail wire 4 segment distance back of moving is stuck in the outside of flexible pipe 1, owing to the internal diameter of bail wire 4 adds the thickness of flexible pipe less than the external diameter of metal pipe mouth 2, so when bail wire 4 is stuck in flexible pipe 1 outside, elastic component 8 can extend, tension semi-circular tube 6 and half-round bar 7, flexible pipe 1 is firmly clamped on metal pipe mouth 2 the most at last。When dismounting, screw out fixing cylinder 3 and just may be used。In sum, the one that this utility model provides connects reliable pipe joint, simple in construction, and energy is installing/dismounting quickly, and connection sealing is good, it is not easy to cause leakage。

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model。
