Description
Technical field
The utility model relates to the production technical field of weldless tube, and specifically, the utility model relates to a kind of weldless tube with link.
Background technique
At present, weldless tube is that one has hollow section, periphery does not have jointed rectangular steel.Along with growth in the living standard, the machinery of processing and carrier mostly has high safety and reliability requirement for equipment and materials, original common weldless tube processing technology, may not necessarily adapt to modern industry environment for the safety of the industries such as logistics and reliability requirement.Original weldless tube is easily corroded in use, and weldless tube strength ratio is more weak, shortens the working life of weldless tube, and the replacing of weldless tube, installation and maintenance are cumbersome, also also exists and is connected unstable defect with installation connecting element.Therefore, those skilled in the art need badly provides a kind of rational in infrastructure, weldless tube with link that stability is good, to realize the docking between weldless tube, ensures the quality of weldless tube.
Model utility content
The technical problems to be solved in the utility model is: provide a kind of rational in infrastructure, weldless tube with link that stability is good, to realize the docking between weldless tube, ensures the quality of weldless tube.
The utility model solves the technological scheme that its technical problem adopts: provide a kind of weldless tube with link, comprise the first body and the second body, the inside of described first body and the second body all has through-hole structure, the end of described first body is provided with socket, described socket is L-shaped, its surface has internal thread, the end of described second body is provided with joining part, described joining part is bar shaped, its surface has outside thread, the profile of described socket and described joining part adapts, and be threaded connection, the end cross-sectional of described first body has annular groove, the end cross-sectional of described second body has the annular relief adapted with described annular groove.
Preferably, described socket has the first bending edge and the second bending edge, and described second bending edge has internal thread.
Preferably, described first bending edge is consistent with the height of described joining part.
Preferably, described annular groove has internal thread.
Preferably, described annular relief has the outside thread adapted with described annular groove.
The utility model provides a kind of weldless tube with link, designed by the docking of socket and joining part, the docking between weldless tube can be realized, simultaneously link by thread contact evenly, in addition, by the design of annular groove and annular relief, further define the position between weldless tube, prevent from producing displacement between weldless tube, improve the anti-twisting property of screw thread simultaneously, take into account the consideration of stress equilibrium and stability, make between two weldless tubes, to realize perfect docking, ensure that link has permanent working life.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation with the weldless tube preferred embodiment of link of the present utility model.
[in figure reference character]:
10. the first body, 20. second bodys, 30. through-hole structures, 40. sockets, 50. joining part, 60. annular grooves, 70. annular relief.
Embodiment
For making content of the present utility model clearly understandable, below in conjunction with Figure of description, content of the present utility model is described further.Certain the utility model is not limited to this specific embodiment, and the general replacement known by those skilled in the art is also encompassed in protection domain of the present utility model.Secondly, the utility model detailed statement that utilized schematic diagram to carry out, when describing the utility model example in detail, for convenience of explanation, schematic diagram, should in this, as to restriction of the present utility model not according to general ratio partial enlargement.
Above-mentioned and other technical characteristics and beneficial effect, by conjunction with the embodiments and accompanying drawing 1 weldless tube with link of the present utility model is described in detail.As shown in Figure 1, Fig. 1 is the structural representation with the weldless tube preferred embodiment of link of the present utility model.
As shown in Figure 1, the utility model provides a kind of weldless tube with link, comprise the first body 10 and the second body 20, the inside of the first body 10 and the second body 20 all has through-hole structure 30, the end of the first body 10 is provided with socket 40, described socket 40 is L-shaped, its surface has internal thread, the end of the second body 20 is provided with joining part 50, joining part 50 is in bar shaped, its surface has outside thread, socket 40 adapts with the profile of described joining part 50, and be threaded connection, the end cross-sectional of the first body 10 has annular groove 60, the end cross-sectional of the second body 20 has the annular relief 70 adapted with annular groove 60.
Concrete, in the present embodiment, socket 40 has the first bending edge and the second bending edge, and wherein the second bending edge has internal thread, the first bending edge is consistent with the height of joining part 50.
In order to improve connection tightness further, annular groove 60 having internal thread, meanwhile, annular relief 70 having the outside thread adapted with described annular groove 60.
In sum, the utility model provides a kind of weldless tube with link, designed by the docking of socket and joining part, the docking between weldless tube can be realized, simultaneously link by thread contact evenly, in addition, by the design of annular groove and annular relief, further define the position between weldless tube, prevent from producing displacement between weldless tube, improve the anti-twisting property of screw thread simultaneously, take into account the consideration of stress equilibrium and stability, make between two weldless tubes, to realize perfect docking, ensure that link has permanent working life.
