Abstract

The utility model discloses a connecting pipe. The connecting pipe comprises a metal plate which is rolled into a tubular shape, wherein two side walls of the metal plate are welded together to form a weld line, a window is formed on the metal plate, and the weld line is connected with the window. The connecting pipe is energy-saving and convenient to operate, and saves manpower.

Description

A kind of connecting tube
Technical field
The utility model relates to a kind of connecting tube.
Background technique
In the prior art, the connecting tube application scenarios is wider, such as, in some frame structures, connecting tube is good support beam, connecting tube in use, as link, greatly welding is for some thicker connecting tubes, in actual mechanical process, because soldering appliance can not stretch in the connecting tube, can only connecting tube and miscellaneous part be welded by external margin, still, as link, want to reach due intensity, only welding from external margin not only wastes more scolder but also expends more manpowers, in addition, built-up welding very easily causes rosin joint, finally cause the consequence that is difficult to expect, propose a kind of connecting tube in the prior art, comprise tube wall, offer a window at tube wall, also comprise the slug that to fill up window.When connecting tube need to weld with other link, at first external margin and the link with connecting tube welds, then, by window welding equipment is entered, and make between the internal edge of connecting tube and the link and weld, if the connecting tube internal diameter is enough large, even the people is entered in the connecting tube by window weld, after welding is finished between the internal edge of connecting tube and the link, again slug is cooperated welding and block window.Owing to not only welding from external margin between connecting tube and the link, and the edge is strengthened internally, so that the welded structure intensity between connecting tube and the link is stronger, namely can produce a desired effect without built-up welding, reduce the rosin joint possibility, so that the use of this connecting tube is more safe and reliable.There are the following problems for above-mentioned connecting tube: because the table wall of the connecting tube after the moulding is arc, cuts out one window thereon and have certain operation easier, the wasting manpower and material resources even operate successfully, also may cause damage to the table wall of connecting tube, demands urgently improving.
The model utility content
For the problem that prior art exists, the purpose of this utility model is to propose a kind of connecting tube, and is not only energy-conservation by in conjunction with the utility model, and easy to operate, saves manpower.
For reaching this purpose, the utility model by the following technical solutions:
A kind of connecting tube comprises a sheet metal that is rolled into tubulose, and the welding of described sheet metal two side is formed bonding wire, offers a window on the described sheet metal, and bonding wire connects described window.
Described bonding wire overlaps with described window sideline.
Described window adopts slug welding to fill up.
Based on disclosing of above technological scheme, the utility model possesses following beneficial effect:
The utility model is in actual mechanical process, before sheet metal is not rolled, at first cut out window along the one sideline, at this moment, it is tabular that sheet metal is, cutting out a window at its place, sideline only needs common cutting machine to finish, simple to operate, then by plate bending rolls the sheet metal that cuts out window is rolled, weld at two sidewalls to the sheet metal behind the roll-forming, because this moment, window was on the bonding wire, so that the minimizing of the position of welding, thereby more energy-conservation.
Description of drawings
Fig. 1 is the utility model embodiment 1 structural representation;
Wherein: 1, sheet metal; 11, bonding wire; 2, window; 3, slug.
Embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment:
Embodiment 1
A kind of connecting tube comprises a sheet metal 1 that is rolled into tubulose, and the welding of sheet metal 1 two side is formed bonding wire 11, offers a window 2 on the sheet metal 1, and bonding wire 11 connects windows 2.Bonding wire 11 overlaps with window 2 sidelines.Window 2 adopts a slug 3 welding to fill up.
In actual mechanical process, before sheet metal 1 is not rolled, at first cut out window 2 along the one sideline, this moment, sheet metal 1 was tabular, cutting out the common cutting machine of 2 needs of a window at its place, sideline can finish, simple to operate, then by plate bending rolls the sheet metal 1 that cuts out window 2 is rolled, weld at two sidewalls to the sheet metal 1 behind the roll-forming, because this moment, window 2 was on the bonding wire 11, so that the minimizing of the position of welding, thereby more energy-conservation.
The above; it only is the better embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to the technical solution of the utility model and inventive concept thereof, all should be encompassed within the protection domain of the present utility model.
