For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of water pipe bending connection at waterpipe jointing place.

For achieving the above object, the utility model provides following technological scheme: a kind of water pipe, comprise body, described body one end is provided with the ring coaxially arranged with body, the other end of described body is provided with boss, and the outer side wall shape of described boss is sphere, and the outer side wall of described boss coordinates with ring inner wall sealing, described body is connected to end successively, is connected with retention mechanism between described body.

As preferably, the retainer ring that described retention mechanism comprises grab, handle and is set on tube wall, described handle and retainer ring are rotationally connected, and described handle and grab are distributed in the both sides of retainer ring and handle and grab are rotationally connected.

As preferably, described handle is provided with the projection abutted with retainer ring.

As preferably, described retention mechanism comprises rotating shaft, and described rotating shaft comprises central shaft and running shaft, and described handle is connected by central axis with retainer ring, and described handle and grab are rotationally connected by running shaft.

As preferably, described retainer ring is provided with support, and described support is rotationally connected by central shaft and handle.

As preferably, described grab has two at least, and is symmetrically distributed on the outer peripheral surface of body.

As preferably, described retainer ring inwall is provided with positioning key, and described body is provided with the groove coordinated with positioning key.

As preferably, described ring inwall is provided with seal ring, and described seal ring and boss are sealed and matched.

By adopting technique scheme, in this New type water pipe, one end of body is provided with the ring coaxially arranged with body, the other end of body is provided with the boss coordinated with ring, be connected to end successively between body, the outer side wall shape of boss is sphere, the angle that the outer side wall spherical rotation of boss is certain, thus make body can bend some angles, adjacent tubes jointing is also provided with retention mechanism, for fixing adjacent two bodys, retention mechanism comprises grab, handle, rotating shaft and the retainer ring be set on body, rotating shaft is divided into central shaft and running shaft, thus fixing adjacent two bodys, and body jointing is provided with a seal ring, enhance sealability.This Novel pipe makes body connect fast, and this water pipe and retention mechanism are convenient and swift in connection procedure, time saving and energy saving, saves cost of material.

Embodiment

Referring to figs. 1 through Fig. 5, the embodiment of the utility model water pipe is described further.

A kind of water pipe, comprise body 10, the ring 6 that arranges coaxial with body 10 is welded in one end of body 10, the other end port of body 10 is provided with a boss 4 coordinated with ring 6, boss 4 outer side wall shape is sphere and the outer side wall of boss 4 coordinates with ring 6 inner wall sealing, the outer side wall of boss 4 is spheres, boss 4 can along some angles of spherical rotation, thus make body 10 in the bending connection of jointing, and sphere is fitted with ring 6 inner wall sealing all the time, the sealing of two body 10 joints can not be affected, in addition, adjacent like this two bodys 10 successively head and the tail are communicated with, a circle seal ring 1 is also provided with between ring 6 and boss 4, for enhancing the sealing effect between boss 4 and ring 6, and then increase the sealability of body 10 jointing.

Body 10 is provided with a retention mechanism, this retention mechanism comprises grab 2, handle 5 and the retainer ring 3 be set on body 10 outer wall, wherein, handle 5 and grab 2 are distributed in the both sides of retainer ring 3, in this embodiment, retention mechanism also comprises rotating shaft 14, rotating shaft 14 comprises central shaft 9 and running shaft 12, handle 5 and retainer ring 3 are rotationally connected by central shaft 9, handle 5 and snap fit are rotationally connected by running shaft 12, retainer ring 3 is provided with a support 11, support 11 has a through hole, support 11 connects handle 5 by through hole, certainly, be rotationally connected also can be clamping or articulated manner, in fastener cycle, pull handle 5, central shaft 9 is as fixed rotating shaft, running shaft 12 does circular-rotation along with central shaft 9, time body 10 connects, grab 2 blocks on the boss 4 of adjacent tubes 10, then handle 5 be facing away from grab 2 direction to pull, running shaft 12 moves in a circle, in movement process, grab 2 tightens up gradually, the running shaft 12 of connection grab 2 and handle 5 produces the power to central shaft 9 gradually, fix grab 2, in addition, grab 2 has two at least, and be symmetrically distributed in body 10 circumferentially, grab 2 is deposited in case only having one, the side of body 10 can only be fixed, easily cause the opposite side of body 10 interface built on the sand, occur leaking water problem, at least be provided with the corresponding both sides circumferentially can fixing body 10 interface that two are symmetrically distributed in body 10, reach better fixed effect.

Further optimization such scheme, handle 5 is provided with the projection 13 abutted with retainer ring 3, when pull handle 5 to protruding 13 and retainer ring 3 abut, protruding 13 give the power on retainer ring 3 one body 10 axial directions, retainer ring 3 gives protruding 13 reaction forces, this power fixes the rotation on handle 5 axial direction, thus fixes grab 2, makes fastening effect between body 10 better like this.

Further optimization such scheme, retainer ring 3 inwall is provided with positioning key 7, on body 10, the place of corresponding positioning key 7 is provided with projection, this projection there is a groove 8 coordinated with positioning key 7, during connection pipe body 10, positioning key 7 corresponding matching on groove 8 and retainer ring 3, serves the effect fixing retainer ring 3.

The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
