Abstract
The invention discloses a novel universal change-over tube, which is characterized by comprising an upper connecting tube, a lower connecting tube and a connecting ring, wherein a middle connecting tube is arranged between the upper connecting tube and the lower connecting tube; the connecting ring is arranged between the upper connecting tube and the middle connecting tube; a plurality of change-over tubes are arranged on the connecting ring, and are divided into a first change-over tube, a second change-over tube, a third change-over tube and a fourth change-over tube; and angles between the first change-over tube and the second change-over tube as well as the first change-over tube and the third change-over tube are consistent. The change-over tube can be externally connected with an external connecting pipe under the condition that the length of the tube is insufficient, or when the tube needs to be connected, practical external connecting single tubes are connected with the change-over tube, so that the connecting is convenient, and the practical operation is simple.
Description
Technical field
The present invention relates to the building pipe field, particularly relate to a kind of novel universal crossover connection.
Background technique
Steel pipe not only is used for conveyance fluid and powdery solid; exchange heat energy; manufacturing machine part and container; it still is a kind of economic steel; make the building structure rack with steel pipe; pillar and machinery mount; can weight reduction; save metal 20～40%; and can realize the batch production mechanized construction; (job shop of Tianjin Steel Pipe Corp. is owing to adopted the steelpipe net shelf structure; the actual steel of saving reach 42.9%); make highway bridge with steel pipe and not only can save steel; simplify construction; and can significantly reduce the area of stopping off; save investment and maintenance cost; so the steel of any other type all can not replace steel pipe fully, but steel pipe can instead of part section bar and bar.Steel pipe is very big to the raising relation of the national economic development and human lives's quality, outclass other steel, the manufacturing from people's daily apparatus, furniture, water supply and sewage, air feed, ventilation and heating facility to various agricultural machinery apparatus, the used firearms of exploitation, national defence and space flight of underground resources, bullet, guided missile, rocket etc. all be unable to do without steel pipe.
Be badly in need of a kind of novel universal crossover connection in the market.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of novel universal crossover connection.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of novel universal crossover connection is provided, comprise: go up connecting tube, following connecting tube and fastener rings, be provided with middle connecting tube between described last connecting tube and the described following connecting tube, described going up between connecting tube and the described middle connecting tube is provided with fastener rings, described fastener rings is provided with a plurality of crossover connections, described crossover connection is divided into first crossover connection, second crossover connection, the 3rd crossover connection and the 4th crossover connection, described first crossover connection and described second crossover connection, angle unanimity between the 3rd crossover connection.
In a preferred embodiment of the present invention, the diameter of described connecting tube down is greater than the diameter of connecting tube in described.
In a preferred embodiment of the present invention, between described crossover connection and the described fastener rings by being welded to connect.
In a preferred embodiment of the present invention, described crossover connection is hollow tubular.
The invention has the beneficial effects as follows: novel universal crossover connection of the present invention, this crossover connection can be under the not enough situation of tube length the adjunction externally connected pipe, perhaps needs are many-sided be connected pipe in, practical external single tube is connected with crossover connection, easy to connect, practical simple to operate.
Description of drawings
Fig. 1 is the perspective view of a preferred embodiment of novel universal crossover connection of the present invention;
The mark of each parts is as follows in the accompanying drawing: 1, go up connecting tube, and 2, connecting tube down, 3, middle connecting tube, 4, fastener rings, 5, first crossover connection, 6, second crossover connection, the 7, the 3rd crossover connection, the 8, the 4th crossover connection.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby protection scope of the present invention is made more explicit defining so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that.
See also Fig. 1, Fig. 1 is the perspective view of a preferred embodiment of novel universal crossover connection of the present invention.
The invention discloses a kind of novel universal crossover connection, comprise: go up connecting tube 1, following connecting tube 2 and fastener rings 4, connecting tube 3 in being provided with between described last connecting tube 1 and the described following connecting tube 2, described going up between connecting tube 1 and the described middle connecting tube 3 is provided with fastener rings 4, described fastener rings 4 is provided with a plurality of crossover connections, described crossover connection is divided into first crossover connection 5, second crossover connection 6, the 3rd crossover connection 7 and the 4th crossover connection 8, described first crossover connection 5 and described second crossover connection 6, angle unanimity between the 3rd crossover connection 7, this crossover connection can be under the not enough situation of tube length the adjunction externally connected pipe, perhaps in the many-sided linking of needs pipe, practical external single tube is connected with crossover connection.
In a preferred embodiment of the present invention, the diameter of described connecting tube 2 down can extend or shorten greater than the diameter of connecting tube 3 in described.
In a preferred embodiment of the present invention, by being welded to connect, connect closely difficult loosening between described crossover connection and the described fastener rings 6.
In a preferred embodiment of the present invention, described crossover connection is hollow tubular, and convenient and single outer connecting pipe links to each other.
Novel universal crossover connection of the present invention has solved the defective in the technological scheme, this crossover connection can be under the not enough situation of tube length the adjunction externally connected pipe, perhaps in the many-sided linking of needs pipe, practical external single tube is connected with crossover connection, and is easy to connect, practical simple to operate.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
