Abstract
The utility model discloses a pipe connector structure, comprising a pipe body and a pipe connector which is provided with an outer thread; a sleeve is arranged inside the port of the pipe body; a protruding point or a protruding line section, which is matched with the thread of the pipe connector, is arranged at the inner wall inside the sleeve; screwing connection is used for the sleeve and the pipe connector. The protruding point or the protruding line section is an inward evenly-distributed protruding point or a protruding line section. The sleeve is sleeved on the pipe body which is then screwed with the pipe connector; a die extrusion mode is used while in production on the inner wall of the sleeve, producing a thread which is matched with the thread of the pipe connector and is formed by the protruding point or the protruding line section. The utility model has the advantages of guaranteeing the conformity in size when the pipe body and the pipe connector are connected through the sleeve because of using even extrusion for the die, improving the production quality, optimizing the product design and greatly improving the whole strength and anti-torsion force for the pipe body.
Description
Technical field
The utility model relates to a kind of pipe joint structure, is meant a kind of threaded coupling structure of the thin walled tube that is used to support especially.
Background technique
In use all there is the problem that interconnects of tubing termination in all kinds of tubing.Can adopt bonding way during connection, this is used in the heavy caliber nonmetallic material pipe morely; For metal tube, small-bore nonmetallic pipe, then many employings are welded and are threaded.When being threaded, can adopt the tubing termination is internal thread, and the tubing termination that matches is that outside thread is the Placement of yin-yang match; Perhaps, the tubing termination is an internal thread, and other establishes a pipe joint that two bodys are engaged togather, and the two ends of pipe joint are outside thread, reaches the purpose of extending or turning to thus; At this moment pipe joint can be in-line, L shaped, T shape, cross or other multidirectional form.But in the process that the double thread linkage structure is processed, have many insoluble realistic problems: owing to must carry out screw thread processing to the tubing termination, therefore the thickness to tube wall just has certain requirement, otherwise can't guarantee join strength and working life, but the increase of thickness had both improved the cost of product, made product become clumsy again and had lost anima; So when tube wall is thin when being unsuitable for machining screw, structure at mouth of pipe assembling nut has appearred, nut and mouth of pipe interference fit, though at this moment bulk strength meets the requirements, but manufacturing procedure is many, complex process degree height, as the pipe joint of Chinese ZL02268275.9 patent " steel-plastic composite pipe joint " description.From the Chinese patent open source literature of retrieving relevant pipe joint as seen, the pipe joint of being discussed relates to liquid transmission line more, as Chinese ZL02242240.4 patent " steel-plastic pipe union ", and the then rare discussion of connection of conventional support tube.
Summary of the invention
The purpose of this utility model provides the threaded coupling structure of the thin walled tube of a kind of conventional supporting effect.
The utility model can be realized in the following manner:
A kind of pipe joint structure comprises body and pipe joint, and pipe joint is provided with outside thread, is provided with a sleeve pipe in the body port, and internal surface of sleeve pipe is provided with salient point or the convex line section that the screw thread with pipe joint is complementary, and sleeve pipe and pipe joint are screwed together.
Described salient point or the convex line section that is complementary with the pipe joint screw thread is inside equally distributed salient point or convex line section.
The utility model compared with prior art has following advantage:
The utility model adopts behind the body fit sleeve pipe Placement that screws togather with pipe joint again, adopt the method for mould extruding on internal surface of sleeve pipe, to make during production and the pipe joint screw thread is supporting " screw thread " be made up of salient point or convex line section, owing to utilize mould to push equably, therefore guaranteed conformity dimensionally when body is connected by sleeve pipe with pipe joint, improved quality of product, optimize product specification, improved the bulk strength and the twisting resistance of body greatly.
Description of drawings
Accompanying drawing 1 is that the complete section master after the utility model assembling looks enlarged diagram;
Accompanying drawing 2 is that the utility model casing threads is the exploded sketch of salient point;
Accompanying drawing 3 is that the utility model casing threads is the exploded sketch of convex line section.
Specific embodiments
With reference to accompanying drawing.The utility model be the pipe joint 2 that adopts can be in-line, L shaped, T shape, cross or other multidirectional can with the sleeve pipe 3 supporting shapes that are connected, body 1 inwall is a smooth inner wall, sleeve outer wall and inboard wall of tube body are complementary, its main key points in design is to form several inside salient points or convex line section 11 at sleeve pipe 3 inwalls through punching press or extruding, promptly utilizes salient point or convex line section to replace screw thread.When screwing togather with pipe joint behind body fit sleeve pipe, salient point or convex line section and pipe joint screw thread are realized good engagement again.
Adopt said structure, can make between sleeve pipe and the pipe joint to revolve the lock engage thread salient point or the convex line section of internal surface of sleeve pipe embedded in the screw thread of pipe joint, sleeve pipe is firmly combined with screw-in version with pipe joint.Because this pipe joint structure adopts behind body fit sleeve pipe the Placement that screws togather with pipe joint again, improved the bulk strength and the twisting resistance of body greatly.
Claims (3)
1, a kind of pipe joint structure comprises body (1) and pipe joint (2), and pipe joint is provided with outside thread, it is characterized in that: be provided with a sleeve pipe (3) in the body port, this sleeve pipe and pipe joint are screwed together.
2, pipe joint structure according to claim 1 is characterized in that: described internal surface of sleeve pipe is provided with salient point or the convex line section (11) that the screw thread with pipe joint is complementary.
3, pipe joint structure according to claim 2 is characterized in that: the salient point or the convex line section that are complementary with the pipe joint screw thread are inside equally distributed salient point or convex line section.
