A kind of steel pipe linkage
The utility model belongs to technical field of buildings, relates to a kind of steel pipe linkage.
In building construction process, must scaffold erecting, this scaffold mainly be for the workman in the constructing operation process, workman person moves on exterior wall or interior wall and provides convenience; And safeguard the safety that scaffold is peripheral, scaffold mainly contains bamboo, timber, pipe and synthetic materials etc., at present; The connected mode of use steel pipe has only the connection of level or vertical direction in the building; Use singlely, can't satisfy employed requirement in the building, and the junction that two steel pipes connect is insecure; Loosening easily, therefore there is potential safety hazard.
Summary of the invention
To the deficiency that exists in the background technology, the purpose of the utility model is to provide a kind of steel pipe linkage, and this steel pipe linkage is connected firmly, and is safe in utilization, can realize multidirectional connection.
For realizing above-mentioned purpose; The utility model provides following technical scheme: a kind of steel pipe linkage; It is characterized in that: comprise steel pipe and cross-connect, described steel pipe two ends are provided with internal thread, and described cross-connect has the cylinder that extends to six direction; Form external screw thread on this cylinder, said cross-connect is connected with the steel pipe of its both sides through screw thread.
Cylinder on the above-mentioned cross-connect has been disposed radially first through hole, and the two ends of said steel pipe have been disposed radially second through hole.
When above-mentioned steel pipe and cross-connect passed through threads engaged, the first above-mentioned through hole was relative with second through hole, and passes through bolt.
Above-mentioned cross-connect adopts the mould steel manufacturing.
The beneficial effect that the utility model is compared prior art is: the cross-connect in the utility model is simple in structure, and is easy to process, and its cross-connect and steel pipe are connected firmly; Safe and reliable; Can fast two steel pipes be connected, easy accessibility, and can realize multidirectional connection; Provide cost savings simultaneously, practical.

Fig. 1 is the sketch map of the utility model.
Label implication among the figure: 1-steel pipe; 2-second through hole; The 3-cross-connect; The 31-cylinder; 32-first through hole.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
As shown in Figure 1; A kind of steel pipe linkage; Comprise steel pipe 1 and cross-connect 3, be provided with internal thread, and cross-connect 3 has the cylinder 31 that extends to six direction at the two ends of steel pipe 1; All form external screw thread on the every cylinder 31, said cross-connect 3 is connected with the steel pipe 1 of its both sides through screw thread.
Cylinder 31 on the above-mentioned cross-connect 3 has been disposed radially first through hole 32, and the two ends of said steel pipe 1 have been disposed radially second through hole 2.
When above-mentioned steel pipe 1 passed through threads engaged with cross-connect 3, the first above-mentioned through hole 32 was relative with second through hole 2, and through bolt, can further steel pipe be positioned vertically like this, prevented that steel pipe from rotating.
Above-mentioned cross-connect 3 adopts the mould steel manufacturing, the application life of using mould steel can improve cross-connect 3, intensity and fastness in the time of can strengthening 1 connection of two steel pipes simultaneously.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and modification, these improvement and modification also should be regarded as the protection domain of the utility model.
