Abstract
The invention discloses a pipeline joint and belongs to the technical field of water heating pipe fittings. The pipeline joint comprises an outer pipe sleeve; an inner pipe sleeve with the two ends stretching out of the outer pipe sleeve is sleeved with the outer pipe sleeve; the two ends of the inner pipe sleeve are both sleeved with end sleeves; one end of each end sleeve is in threaded connection with the outer pipe sleeve; the apertures of the other end of each end sleeve and the two ends of the inner pipe sleeve are all gradually decreased from inside to the ends; and wall bodies at the two ends of the inner pipe sleeve are provided with grooves towards the ends of the inner pipe sleeve. The pipeline joint can solve the problems that existing pipeline installation is troublesome, a pipeline of one specification can only be connected with a nut of the corresponding specification, and the function is single.
Description
Technical field
The present invention relates to water heating pipe fittings technical field, especially a kind of joint being connected for two pipelines.
Background technology
Pipe joint is the necessary part that short tube connects into pipeline, what existing pipe joint adopted is the nut with inner hole thread, to offer, at pipeline external wall, the screw thread matched with described nut inner hole screw thread in advance during connection, then make described pipeline be connected with described nut thread, between described pipeline and described nut, be provided with sealing ring; This connected mode also exists: install cumbersome, and the specification of a kind of pipeline can only be connected with the nut of dimension, the problem that function is more single.
Summary of the invention
The technical problem to be solved is to provide a kind of pipe joint, and this pipe joint can solve existing pipeline and install cumbersome, and the specification of a kind of pipeline can only be connected with the nut of dimension, the problem that function is more single.
In order to solve the problems referred to above, the technical solution adopted in the present invention is: this pipe joint, include outer tube sleeve, the interior pipe box that its two ends are stretched out respectively in outer tube sleeve it is set with in described outer tube sleeve, the two ends of said inner tube set is respectively installed with end set, described end overlaps one end and described outer tube sleeve threaded engagement, the aperture at the described end set other end and said inner tube set two ends is gradually reduced by its termination introversive, and the wall body at said inner tube set two ends offers multiple groove towards interior pipe box termination openings respectively.
In technique scheme, technical scheme is it may also is that be provided with sealing ring between described outer tube sleeve and described end set more specifically; The outer wall at described outer tube sleeve two ends all offers external screw thread, and one end inwall of described end set offers female thread respectively, and described outer tube sleeve two ends connect with respective end external threading respectively.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
1, owing to being set with interior pipe box in outer tube sleeve, the wall body at interior pipe box two ends offers multiple groove towards interior pipe box termination openings respectively, and the two ends of interior pipe box is respectively installed with the end set of its one end and outer tube sleeve threaded engagement, interior pipe box two ends and end set their aperture of the other end corresponding to interior pipe box two ends are gradually reduced by its termination introversive, therefore, when two pipelines are connected, only need to two pipelines be inserted in interior pipe box respectively, turning end set, the termination that end set is gradually reduced makes out slotted interior pipe box termination shrink, can by pipeline banding. It need not offer screw thread at pipeline external wall in advance, easy for installation, and holds set aperture to be gradually reduced by its termination introversive, has variable surplus, therefore, can connect the pipeline of many specifications.
2, owing to being provided with sealing ring between outer tube sleeve and end set, liquid can be avoided to make screw thread get rusty, play the effect increased the service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is that Figure 1A-A locates sectional view.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Pipe joint shown in Fig. 1, Fig. 2, include outer tube sleeve 1, the interior pipe box 2 that its two ends are stretched out respectively in outer tube sleeve 1 it is set with in outer tube sleeve 1, the two ends of interior pipe box 2 is respectively installed with end set 3, the outer wall at outer tube sleeve 1 two ends all offers external screw thread 11, one end inwall of end set 3 offers female thread respectively, and outer tube sleeve 1 two ends are overlapped 3 threaded respectively with respective end, is provided with sealing ring between outer tube sleeve 1 and end set 3; The aperture at end set 3 other ends and interior pipe box 2 two ends is gradually reduced by its termination introversive, and the wall body at interior pipe box 2 two ends offers multiple groove towards interior pipe box 2 termination openings respectively. When pipeline connects, inserting in interior pipe box respectively by two pipelines, turning end set is by pipeline banding. It need not offer screw thread at pipeline external wall in advance, easy for installation, and holds set aperture to be gradually reduced by its termination introversive, has variable surplus, therefore, can connect the pipeline of many specifications.
