In the following detailed description of the present invention, certain specific details are set forth. However, the present invention may be fully understood by those skilled in the art for those parts not described in detail.
Furthermore, those skilled in the art will appreciate that the drawings are provided solely for the purposes of illustrating the invention, features and advantages thereof, and are not necessarily drawn to scale.
Also, unless the context clearly requires otherwise, throughout the description and the claims, the words "comprise", "comprising", and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is, the meaning of "includes but is not limited to".
FIG. 1 is a schematic view of a thin-walled tube connection according to an embodiment of the present invention; in fig. 1, a thin-walled tube connection structure includes a first tube 1 and a second tube 5, wherein the butt-joint ports of the first tube 1 and the second tube 5 are respectively provided with an insertion structure, and the insertion structure is used for connecting the first tube 1 and the second tube 5 into an integral structure; key grooves are formed in the circumferential direction of the inserting structure, and connecting keys 4 are embedded in the key grooves; the connecting key 4 is used for transmitting axial tension and circumferential torsion between the first pipe body 1 and the second pipe body 5.
The thin-wall pipe connecting structure of the embodiment is connected into an integral structure through the inserting structures respectively arranged at the connecting ports of the two pipe bodies, then is further fixedly connected by using the connecting key 4, and realizes the transmission of axial tension and circumferential torsion between the two connecting pipe bodies through the connecting key 4, and the two pipe bodies can completely meet the requirement of site construction operation strength after being connected; the thin-wall pipe is connected by the connecting structure, auxiliary connecting equipment does not need to be arranged on site, and site environment requirements such as open fire or electricity preparation and the like do not need to be used, so that the problem that the existing thin-wall pipe connecting mode needs to be connected in an auxiliary mode by adding equipment on site or the construction cost is increased is well solved; or because the open fire needs to be used, the construction is carried out on the oil drilling and production site, particularly in the environment which does not allow the open fire to be used, and the problem of potential safety hazard exists.
Preferably, the plug formations are evenly arranged along the docking port. Obviously, the splicing structures are uniformly arranged, so that when the first pipe body 1 and the second pipe body 5 transmit axial tension and circumferential torsion, the axial tension and the circumferential torsion can be equally distributed to each splicing structure, namely, the stress of each splicing structure is uniform, the force transmission of each splicing structure is uniform, and therefore the connection structure is more stable.
In fig. 1, the connection key 4 is a circular arc key. The circular arc key is selected, and meanwhile, the key groove is also designed to be the circular arc key groove, so that the circular arc key has the advantages of being simple to process and convenient to install and disassemble.
In fig. 1, the insertion structure is a socket structure 9 and a plug structure 7 that are disposed on the butt joint ports of the first pipe 1 and the second pipe 5, and the first pipe 1 and the second pipe 5 are inserted into an integral structure through the plug structure 7 and the socket structure 9.
The socket structure 9 of the first pipe body 1 corresponds to the plug structure 7 of the second pipe body 5, and the plug structure 7 of the first pipe body 1 corresponds to the socket structure 9 of the second pipe body 5, so that the first pipe body 1 and the second pipe body 5 can be plugged together to form an integral structure.
Preferably, during processing, the butt joint ports of the first pipe body 1 and the second pipe body 5 can be equally divided into even number, for example, 6, and then, three of the even number are processed into the socket structure 9 at intervals, and the other three are naturally formed into the plug structure 7; of course, the amount may be 8 parts or 10 parts, and the processing method is the same. By adopting the processing mode, the inserting structures of the first pipe body 1 and the second pipe body 2 are completely the same, so that whether the matching of the interfaces is proper or not is not considered when the two pipe bodies are connected, and meanwhile, the processing can be simplified.
Preferably, the number of socket structures 9 is 3-5. If the number of the connecting keys 4 is too small, the number of the connecting keys is small, the stability of the connecting mechanism is not good enough, and if the number of the connecting keys is too large, the performance of the connecting structure is not increased, and the processing cost is increased.
In fig. 1, a first keyway 3 is provided on at least one of the plug formations 7 of the first body 1; a second keyway 10 is provided on at least one of the plug formations 7 of the second body 5; the first key groove 3 and the second key groove 10 constitute the key grooves.
