Abstract
The utility model discloses a rapid inserting tube connector. An existing tube connector is inconvenient to install, short in service life and poor in stability. The rapid inserting tube connector is provided with at least connector. The inserting connector is formed by an inner ring wall, an outer ring wall and an inserting opening formed between the inner ring wall and the outer ring wall. A sealing ring is arranged on an outer wall of the inner ring wall. An annular groove is formed in the middle portion of an inner wall of the outer ring wall. An elastic clamping ring capable of stretching along the radial direction is arranged in the annular groove. An expending slope facing the outer end of the inserting connector is arranged at the inner side of the elastic clamping ring. A clamping point is formed in the portion, with the minimum inner diameter, of the elastic clamping ring. A press cap is arranged at the position of an end opening of the inserting connector. The inner end of the press cap points to the slope of the elastic clamping ring. Inserting positions are formed between the press cap and the inner ring wall and between the elastic clamping ring and the inner ring wall. A tube can be conveniently inserted or pulled out without assistance of any tool. After the tube is inserted, the clamping point of the elastic clamping ring is clamped on an outer wall of the tube. When the tube is pulled out, the clamping point of the elastic clamping ring prevents the tube from being pulled out.

Embodiment
Below in conjunction with Figure of description the utility model is described further.
Fast spigot joint of the present utility model, such as Fig. 1 a, 1b, shown in 2, have at least two joints that communicate with each other on its body 01, at least one joint is by internal ring wall 12, external annulus 13 and be formed on internal ring wall 12, interface 14 between the external annulus 13 forms grafting joint 11, establish seal ring 15 on the outer wall of internal ring wall 12, the middle part of external annulus 13 inwalls is provided with annular groove 16, the snap ring 17(that these annular groove 16 interior storings can radially be opened is as making and arrange opening with metal), the inboard of snap ring 17 has towards the expansion inclined-plane 18 of interface 14 outer ends, and make card point 19 at the minimum diameter place of snap ring 17, the port of interface 14 configures a pressure cap 110, the expansion inclined-plane 18 of snap ring 17 is pointed in the inner of pressure cap 110, between pressure cap 110 and internal ring wall 12, form insertion position 111 between snap ring 17 and the internal ring wall 12.
When grafting joint connecting pipe 02, only the port of pipe 02 111 need to be inserted interfaces 14 and gets final product from the insertion position, insert in the process of interface 14, the port of pipe act on the expansion inclined-plane 18 of snap ring 17 inboard from snap ring 17 with snap ring to radially opening, until card point 19 relies on the elastic card of snap ring to realize connecting at the outer surface of pipe 02, can not directly pipeline be extracted, and seal ring 15 is compressed in realization sealing between internal ring wall 12 and the pipeline 02; If wish is outwards extracted pipe 02, first pressure cap 110 is inwardly pushed, then the inner of pressure cap 110 acts on the expansion inclined-plane 18 of snap ring 17 from the inboard of snap ring snap ring to radially opening, and order card point 19 is thrown off from the outer surface of pipe 02, can extract pipe; Swift to operate, convenient.
As further improving and replenishing technique scheme, the utility model also comprises following additional technical characteristics, although Fig. 1 a, 1b, 2 have comprised following all additional technical features, it is preferred embodiment of the present utility model, but the utility model is not limited to this situation, according to specifically acting on they is selected on the described technological scheme of epimere when implementing the utility model.
At first, pressure cap 110 is connected to the port of external annulus 12 by screw thread 112, can avoid pressure cap 110 to lose, and can realize pressure cap is inwardly pushed by the rotation screw thread simultaneously.Further, inboard with pressure cap 110 threaded connection places on the external annulus 12 has vacant section 113, this diameter of vacant section 113 is greater than the diameter of screw thread on the external annulus, this length of vacant section is greater than the length of screw thread on the pressure cap, therefore, pressure cap can move with respect to external annulus after being threaded, and is beneficial to operation.Structure as an alternative, the inner of pressure cap has anti-avulsion section (with respect to the position of pressure cap 110 thread sections), has the anti-avulsion edge (with respect to the position of thread section on the external annulus) that is positioned at oral area on the external annulus, pressure cap is assemblied in movably the oral area of external annulus and deviates from from the oral area of external annulus by interference fit (the anti-avulsion section is positioned at the inboard of anti-avulsion edge, is pressed into by pressure during assembling) the prevention pressure cap of anti-avulsion section and anti-avulsion edge.
Secondly, the inner of pressure cap 110 is established and is moved back card inclined-plane 114, and this moves back card inclined-plane 114 and to expand inclined-plane 18 corresponding, when pressure cap is inwardly pushed, the inner that is beneficial to pressure cap act on the expansion inclined-plane of snap ring inboard from snap ring with snap ring to radially opening.
The 3rd, card point 19 be continuous or dispersion.
The 4th, the outside of snap ring 17 has towards the contraction inclined-plane 115 of interface 14 outer ends, the outside cell wall of annular groove 16 is made consistent with this contraction inclined-plane 115 inclined-plane 116 of tightening, based on this structure, when directly outwards extracting pipe, snap ring 17 can outwards be taken out of, then under the effect of tightening inclined-plane 116, make snap ring 17 tighten by shrinking inclined-plane 115, thus 19 tighter being stuck on the tube wall of order card point.
Fast spigot joint of the present utility model, whole insertion and the process of extracting all need to be by other any instruments, and be convenient, fast, can significantly improve installation efficiency.That specific constructive form can be is straight-through, two logical, threeway, four-way and logical structure how.Seal ring can adopt neoprene to make with zero type circle, and ageing resistance is strong, and all the other fitment material all adopt brass, therefore can greatly increase stability and working life.Simultaneously, it also can be used for the connection such as the plastic pipes such as PPR pipe, PE pipe and aluminium-plastic composite pipe, steel-plastic composite pipe etc.
