Description
Technical field
The present invention relates to pipe and connect the field, particularly a kind of line pipe joint structure.
Background technique
Existing line pipe joint structure, as shown in Figure 6, the capping 2 that main body 1 that pipe connects and pipe connect all is to adopt common multi-thread fine thread 6 to cooperatively interact.Product structure like this not only in die manufacture processing and the assembling mould loaded down with trivial details, and the product that comes out of Mould Machining---main body can be because of the dislocation between the multilayer fine thread of its capping or other bad and very difficult no-float, generally need be through repair repeatedly even just can reach a standard after the threaded fittings of processing mold again; Be that pipe connects the capping mould and puts into production soon on the other hand, the screw thread place of its product has been easy to burr and has needed repairing, and causes die life shorter.And supporting by multi-thread fine thread, also can cause main body and pipe to connect supporting section longer dimension of capping, product weight is overweight, cost up.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of Mould Machining cycle shorter, die life is longer, and the product installation and removal are simpler and easy, quick, the structure that product cost is lower.
In order to realize the foregoing invention purpose, the technological scheme of employing is as follows:
A kind of line pipe joint structure, it comprises a main body and a capping, and described main body and capping are by being threaded, and described screw thread adopts large screw pitch single start thread structure.
What large screw pitch single start thread structure of the present invention adopted is that pitch is the several times of the pipe thread of common same specification, particularly adopt 2-6 doubly, and the present invention is also the same with the common tube screw thread, the corresponding increasing with the increase of product specification of pitch value.
Further, described screw thread comprises the internal thread that is arranged on main body wall and is arranged on the outside thread of capping sidewall that internal thread and outside thread match.
As another kind of structure, described screw thread comprises the outside thread that is arranged on main body wall and is arranged on the internal thread of capping sidewall that outside thread and internal thread match.
The threaded port of described main body is provided with the main body fixing device, is provided with and the corresponding capping fixing device of main body fixing device in the threaded port of described capping.
Described main body fixing device is that the threaded port in described main body is provided with the main body positioning groove, is provided with and the corresponding lid positioning boss of main body positioning groove at the bottom of described capping fixing device is threaded end in described capping.
Particularly, the button bit groove that described main body positioning groove is two symmetries, the button bit boss that described lid positioning boss is two symmetries.
Described screw thread is a trapezoidal thread.
Described screw thread is a V thread screw.
Described screw thread is a square threaded form.
Described screw thread is a buttress thread form.
It is that pvc pipe connects that described pipe connects.
Compare with existing pipe connection technology, the present invention has following characteristics:
1, firm, durable.The technological scheme of patent of the present invention not only is threaded fixingly because pipe connects main body and capping, and the button bit location is arranged each other, limits that their are mutual loosening or break away from, firm, durable; And the pipe of reality connects just screw thread and fixes, if the dynamics of turning round is inappropriate, lasts easily loosening soon or comes off.
2, simple in structure.Pipe of the present invention connects the trapezoidal thread that large screw pitch is all adopted in main body and capping, and the screw thread in the preferred version is the wall scroll trapezoidal thread.Therefore Mould design is simple, and the process-cycle is shorter;
3, assembling is quick, light.The pipe of reality connects, and the multilayer screw thread is arranged, and will firmly turn round tens of circles during assembling and just can put in place.And the pipe of patent of the present invention connects, and only needing to turn round a circle to clockwise direction can put in place;
4, product cost is low.The pipe of patent of the present invention connects the trapezoidal thread that adopts large screw pitch, and is under the suitable situation of function, short more a lot of than the length of the product of reality.So product weight is light, cost is low.For example: ￠ 20 pipes of reality connect weight be 10.5g/ only, and ￠ 20 pipes of patent of the present invention connect weight be 9g/ only.So, more more economical than the product of reality, suitable.

Embodiment
The present invention is described further below in conjunction with accompanying drawing.
As attached illustrated in figures 1 and 2, the invention provides a kind of line pipe joint structure, it comprises a main body 1 and a capping 2, and main body 1 is connected by screw thread 3 with capping 2, and screw thread 3 is steep-pitch threads.The screw initial thread position of main body is provided with main body positioning groove 4, screw thread end position in capping is provided with and the corresponding lid positioning boss 5 of main body positioning groove, wherein main body positioning groove 4 is button bit grooves of two symmetries, and lid positioning boss 5 is button bit boss of two symmetries.
As further preferred version, what screw thread 3 adopted is trapezoidal pitch thread, particularly the wall scroll trapezoidal thread.
During use, hold the non-threaded end of capping 2 earlier with a hand, the another hand is held the non-threaded end of main body 1, and make about both threaded end and aim at, under the situation that keeps capping 2 " motionless ", the hand of holding main body 1 non-threaded end is close to capping 2 then, main body 1 is rotated to clockwise direction, when screw thread complements one another, and hear " clickly " get final product behind the little sound---after the accurate supporting sound of the positioning boss of just positioning groove 4 and the capping 2 of main body 15, promptly finish installation.Obviously, such installation is light, easy, quick.
Accompanying drawing 3 connects main body and capping assembled perspective view for pipe of the present invention.
Accompanying drawing 4 connects the three-dimensional view of main body for pipe of the present invention.
Accompanying drawing 5 connects the three-dimensional view of capping for pipe of the present invention.
Pipe of the present invention connects with the line box and installs and uses, and as shown in Figure 5, overlaps wired box 7 in the outside of capping 2.
Design feature of the present invention is the screw thread that main body and capping all only have the trapezoidal tooth of wall scroll, coarse pitch, and main body and capping have the button bit of location usefulness each other. Like this, not only product installation and removal are simple, quick, and because localization part is arranged, and firm, durable.
