Description

Quick gluing-free reusable connector

Technical Field

The utility model relates to a repeatedly usable connects technical field, specifically is a gluing repeatedly usable connects exempts from fast.

Background

At present, carry out fixed connection through support and screw mostly between the pipeline, but connect not firm still the time-wasting, fixed lock point between the pipeline is too few, and the pipeline is still taken out from the support easily, is connected through sticky mode between pipeline and the pipe joint in addition, but pipe joint after sticky is difficult to be unpack apart and used repeatedly, and no matter be leg joint or sticky connection all can have the problem of pipeline decentraction moreover.

Therefore, a need exists for a quick, glue-free reusable coupling that solves the above problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a to solve the problem that provides among the prior art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a quick gluing repeatedly usable joint of exempting from which characterized in that: including first pipeline, pipe connection head, second pipeline, fixation nut, the processing of pipe connection head both ends is the flower form port, the inside axial processing in the positive middle position of pipe connection head has the diameter to be 3.4 mm's through-hole, the processing of all the other parts of pipe connection head inner wall except the through-hole internal diameter has the sword tooth. The processing of pipe connection head both ends is the mouth of flowering form, the mouth of flowering form makes pipe connection head both ends more easily toward the internal contraction when being extruded by the fixed nut ladder angle again, and the pipe connection head inner wall has the sword tooth, the mouth of flowering form is toward the internal contraction under the effect of fixed nut ladder angle, the sword tooth is along with the contraction effect of the mouth of flowering form on the pipeline outer wall, through the mouth of flowering form toward the internal contraction and the sword tooth is used in the pipeline outer wall, make that be connected between pipeline and the pipe connection head inseparabler.

Further, first pipeline passes through fixation nut fixed mounting in pipe connection head one end, the second pipeline passes through fixation nut fixed mounting at the other end of pipe connection head, the second pipe mounting has the chamfer in the inside one end processing of pipe connection head, the one end internal diameter that the second pipe processing has the chamfer is greater than the diameter of pipe connection head through-hole. The first pipeline internal diameter is 3.2mm, and the pipeline internal diameter after the second pipeline processing chamfer is 3.5mm, and the pipeline internal diameter of second pipe connection head one end is greater than the diameter of pipe connection head through-hole for there is not the problem that the ladder blockked when liquid trickles in the pipeline, makes liquid trickling more smooth in the pipeline.

Furthermore, the inner wall of the fixing nut is provided with an inward protruding ladder corner, and the flower-shaped port of the fixing nut shrinks inward under the action of the ladder corner on the inner wall of the fixing nut when the fixing nut is connected with the pipeline connector through threads. Ladder angle in the fixing nut makes the blossoming form port to the internal contraction, and the contraction through the blossoming form port makes the connection between pipeline and the pipe connection head more firm.

Furthermore, the first pipeline and the second pipeline are fixed in the pipeline connector by the cutter teeth when the flower-shaped ports shrink inwards, and the first pipeline and the second pipeline are concentric with the through holes in the pipeline connector. The sword tooth is in the shrink of blossoming form port with pipeline outer wall multiple spot contact, and to pipeline multiple spot locking point, it is inseparabler to make the relation between pipeline and the pipe connection head, make the pipeline more be difficult to taken out from the pipe connection head, first pipeline internal diameter is 3.2mm, second pipeline internal diameter is 3.5mm, the diameter of pipe connection head through-hole is 3.4mm, and first pipeline, it is very concentric between second pipeline and the through-hole, so do not have the blockking between the high low order ladder when liquid flows into the second pipeline from first pipeline through-hole, liquid can be smooth flow in the pipeline.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the pipeline is pinned by sword tooth multiple spot for connection between the pipeline is more firm, exempts from between pipeline and the pipe connection head moreover sticky, still repeatedly usable to the pipe connection head after dismantling.

2. The pipeline passes through the connection of coupling head, and is very concentric between the pipeline, does not have the high low order ladder to block when liquid flows into the second pipeline through the through-hole from first pipeline moreover, and liquid can be smooth trickling in the pipeline.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example (b): as shown in fig. 1-7, the utility model provides a technical scheme, but sticky repeatedly usable joint is exempted from fast, including first pipeline 1, pipe connection head 2, second pipeline 3, fixing nut 6, pipe connection head 2's material is ya keli, 2 both ends processing of pipe connection head are blossoming form port 5, the inside axial processing of 2 positive positions of pipe connection head has the diameter to be 3.4 mm's through-hole, 2 inner walls of pipe connection head except that all the other partial processing of through-hole internal diameter have sword tooth 4, 2 both ends processing of pipe connection head are blossoming form port 5, can make pipe connection head 2 more easily inwards shrink under the extrusion at fixing nut ladder angle, shrink through pipe connection head 2 drives sword tooth 4 and pipeline multiple spot contact, the multiple spot is locked, make the connection between pipeline and the pipe connection head inseparabler, it is more firm.

First pipeline 1 passes through fixing nut 6 fixed mounting in 2 one ends of pipe connection head, second pipeline 3 passes through fixing nut 6 fixed mounting at 2 other ends of pipe connection head, second pipeline 3 is installed and is processed 30 chamfers in 2 inside one ends of pipe connection head, the one end internal diameter that makes second pipeline 3 process have the chamfer is 3.5mm, the one end internal diameter that makes second pipeline 3 process have the chamfer is greater than the diameter of 2 through-holes of pipe connection head, do not have the blockking of height ladder when making things convenient for liquid to flow in the pipeline.

Outside the position that fixed nut 6 internal diameter got rid of and carry out threaded connection with the pipe connection head, other positions processing have the angle to be 30 toward outside ladder angle of expanding, and the ladder angle is toward interior expansion, blossoming form port 5 is toward the internal contraction under the effect of fixed nut 6 inner wall ladder angle when fixed nut 6 is connected with pipe connection head 2 through the screw thread, first pipeline 1, second pipeline 3 is fixed in pipe connection head 2 by sword tooth 4 when blossoming form port 5 is toward the internal contraction, and first pipeline 1, the through-hole in second pipeline 3 and the pipe connection head 2 is concentric.
