Disclosure of Invention
The utility model aims at the not enough of prior art, provide a structural design is reasonable, and the installation is firm, can effectual multilayer prevent the infiltration, leak or the pipe fitting connecting device that gas leakage phenomenon takes place.
The utility model discloses a realize through following technical scheme: the utility model provides a novel connecting device of pipe fitting comprises hollow pipeline, the hollow pipe fitting of screw thread, its characterized in that: the O-shaped sealing ring and the multi-connected O-shaped ring which are tightly sleeved inside the threaded hollow pipe fitting are further included, the outer hexagonal side locking piece which is screwed in the threaded hollow pipe fitting through the threads is screwed in the nut on the other end of the outer hexagonal side locking piece through the threads, and one end of the hollow pipeline is directly inserted into the other end of the outer hexagonal side locking piece and is locked and connected through the nut.
The hexagonal limit latch fitting is a siphunculus outward, all is provided with the external screw thread outside the both ends head of this siphunculus to be provided with vertical mouthful groove of exploding on one of them external screw thread end surface, the middle part outside of siphunculus is provided with hexagonal limit outward.
An inner cavity wall at one end of the threaded hollow pipe fitting is provided with an internal thread, the outer peripheral wall of the threaded hollow pipe fitting is provided with an outer hexagonal edge, and a first step surface and a second step surface are sequentially arranged at the end of the internal thread of the threaded hollow pipe fitting; the O-shaped sealing ring is arranged on the second step surface, and the multi-connected O-shaped ring is arranged on the first step surface.
The beneficial effects of the utility model reside in that: compared with the prior art, the utility model discloses need not open under the condition of thread tooth at hollow pipeline, through installation O type sealing washer and multiconnector O type circle in the hollow pipe fitting of screw thread, the hollow pipe fitting threaded connection of screw thread is served at outer hexagonal limit latch fitting, hollow pipeline inserts utilizes nut locking on the other end of outer hexagonal limit latch fitting, consolidate through the spanner, make the conjugation degree between hollow pipe fitting of screw thread and the hollow pipeline be connected inseparabler, effectual multilayer has prevented the phenomenon of the infiltration of leaking water or gas leakage and has taken place, can prolong the life of gas pipeline or water pipeling greatly and save the cost of labor.

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.
Referring to fig. 1-3, a novel pipe connection device comprises a hollow pipe 1, a threaded hollow pipe 5, an O-ring 4 and a multi-connected O-ring 3 tightly sleeved inside the threaded hollow pipe 5, an outer hexagonal-side locking piece 2 screwed into the threaded hollow pipe 5, and a nut 6 screwed onto the other end of the outer hexagonal-side locking piece 2, wherein one end of the hollow pipe 1 is directly inserted into the other end of the outer hexagonal-side locking piece 2, and is locked and connected by the nut 6; when an infinite pipeline is needed, an infinite number of short hollow pipelines 1 and threaded hollow pipe fittings 5 are required to be connected in sequence for use, and the hollow pipelines 1 and the threaded hollow pipe fittings 5 are completely connected by nuts 6, outer hexagonal side locking pieces 2, O-shaped sealing rings 4 and multi-connected O-shaped rings 3.
The outer hexagonal side locking piece 2 is a through pipe, external threads are arranged outside two ends of the through pipe, a vertical opening groove 201 is formed in the surface of one external thread end, and an outer hexagonal side is arranged outside the middle of the through pipe; after the bursting groove 201 is locked and connected with the nut 6, the position is meshed with the nut 6 more tightly.
As shown in fig. 2, an inner cavity wall at one end of the threaded hollow pipe fitting is provided with an internal thread, an outer hexagonal edge is arranged on the outer peripheral wall, and a first step surface and a second step surface are sequentially arranged at the end of the internal thread of the threaded hollow pipe fitting; the O-shaped sealing ring is arranged on the second step surface, and the multi-connected O-shaped ring is arranged on the first step surface; when the O-shaped sealing ring is installed, the O-shaped sealing ring 4 is placed on the second step surface 502 in the threaded hollow pipe fitting 5, and then the multi-connection O-shaped ring 3 is placed in the first step surface 501.
