Abstract
The invention discloses a metal connecting pipe, which comprises a pipe wall and a metal plate capable of filling a window, wherein the window is formed on the pipe wall. Surfacing is not required, an expected effect can be achieved, and the possibility of a cold joint is reduced, so that the metal connecting pipe is safely and reliably used.
Description
Technical field
The present invention relates to a kind of metal connecting tube.
Background technique
In the existing technology, the metal connecting tube application scenarios is wider, such as, in some frame structures; Metal connecting tube is good support beam, and metal connecting tube in use as link, welds greatly; For some thicker metal connecting tubes, in actual mechanical process,, can only metal connecting tube and miscellaneous part be welded by external margin 3 because soldering appliance can not stretch in the metal connecting tube; But, as link, want to reach due intensity, only welding from external margin 3 not only wastes more scolder but also expends more manpowers; In addition, built-up welding very easily causes rosin joint, finally causes the consequence that is difficult to expect, demands urgently improving.
Summary of the invention
Problem to existing technology exists the objective of the invention is to propose a kind of metal connecting tube, through combining the present invention, can produce a desired effect without built-up welding, reduces the rosin joint possibility, makes that the use of this metal connecting tube is more safe and reliable.
For reaching this purpose, the present invention adopts following technological scheme:
A kind of metal connecting tube comprises tube wall, on said tube wall, offers a window, also comprises the sheet metal that can fill up said window.
Weld between said sheet metal and the said tube wall.
Based on disclosing of above technological scheme, the present invention possesses following beneficial effect:
Not only weld between the present invention and the link from external margin; And the edge welds internally; Make that the welded structure intensity between metal connecting tube and the link is stronger; Promptly can produce a desired effect without built-up welding, reduce the rosin joint possibility, make that the use of this metal connecting tube is more safe and reliable.
Description of drawings
Fig. 1 is the part-structure schematic representation of the embodiment of the invention 1;
Fig. 2 is the part-structure schematic representation of the embodiment of the invention 1;
Wherein: 1, tube wall; 2, window; 3, external margin; 4, internal edge; 5, sheet metal.
Embodiment
Further specify technological scheme of the present invention below in conjunction with accompanying drawing and through embodiment:
Propose a kind of metal connecting tube, comprise tube wall 1, on tube wall 1, offer a window 2, also comprise the sheet metal 5 that to fill up window 2.Welding between sheet metal 5 and the tube wall 1.
Metal connecting tube need weld with other link; At first the external margin 3 with metal connecting tube welds with link; Then, welding equipment is got into, and make between internal edge 4 and the link of metal connecting tube and weld through window 2; If the metal connecting tube internal diameter is enough big; Even the people is entered in the metal connecting tube by window 2 weld, after welding is accomplished between the internal edge 4 of metal connecting tube and the link, again sheet metal 5 is cooperated welding and blocks window 2.Owing to not only weld between metal connecting tube and the link from external margin 3; And edge 4 is strengthened internally; Make that the welded structure intensity between metal connecting tube and the link is stronger; Promptly can produce a desired effect without built-up welding, reduce the rosin joint possibility, make that the use of this metal connecting tube is more safe and reliable.
The above; Be merely the preferable embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or change according to technological scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
Claims (2)
1. a metal connecting tube comprises tube wall (1), it is characterized in that, on said tube wall (1), offers a window (2), also comprises the sheet metal (5) that can fill up said window (2).
2. metal connecting tube according to claim 1 is characterized in that, welding between said sheet metal (2) and the said tube wall (1).
