The scaffold of present embodiment to connected components in the scaffold assembling process, earlier be inserted into male joint 1 on the lower end mouth of pipe of steel pipe by stationary positioned section 18, and cooperating and going up the lower nozzle end face of steel pipe between the circumferential surface of the interior cover face by last steel pipe and the stationary positioned section of male joint 1 is fixed together both with welding between the edge, male joint location, so that male joint is located along 17 blocks on the lower nozzle end face of last steel pipe, simultaneously female joint 2 is inserted into down by female joint fixed part 25 on the upper end mouth of pipe of steel pipe, between the interior cover face by following steel pipe and the circumferential surface of female joint fixed part 25 cooperate and down upper orifice end face and the female joint of the steel pipe welding of locating between the edge both are tightened together, so that female joint is located along 24 blocks on the upper orifice end face of following steel pipe; Then under the situation of the female protruding stupefied mutual alignment of mark in the public protruding stupefied and female joint 2 of the mark in the male joint 1, the linkage section 12 of male joint 1 rotated be assemblied in the rotation space of female joint 2, so that the interior cover face of the positioning section 13 of male joint 1 and female joint 2 is fixingly fitted, non-return lock dog 14 passes from dodge breach, block 22 passes from dodge the gap; Relatively rotate male and female joint 1,2 at last along clockwise direction, be difficult to relatively rotate to both, so that the trailing flank of block 22 and non-return lock dog 1,2 is combined together along circumferential block, and rely on the stiction between the trailing flank of block and non-return lock dog 1,2 to make male and female joint 1,2 relative spinners together.Therefore the scaffold of present embodiment to connected components in the scaffold assembling process, relative spinner by block 22 and non-return lock dog 14 be connected the structure that two steel pipes to be connected is docking together and connects by spinner to two steel pipes of butt joint at axial limiting, two steel pipe connection reliability that guarantee in scaffold, to dock and stability.
In the above-described embodiments, have in the male joint and be used for the coaxial interior stationary positioned section of the mouth of pipe that is inserted into corresponding steel pipe, have in the female joint and be used for the coaxial interior female joint fixed part of the mouth of pipe that is inserted into corresponding steel pipe, so that it is public, the coaxial respectively plug-in mounting of female joint is fixed on the corresponding steel pipe mouth of pipe, and the cooperation between the interior cover face of the outer peripheral face of dependence stationary positioned section and female joint fixed part and the mouth of pipe guarantees the stability that plug-in mounting is fixing, in other embodiments, public, female joint also can directly be fixed on the mouth of pipe end face of corresponding steel pipe, and removes the part in the mouth of pipe that stretches into steel pipe.
In the above-described embodiments, it is corresponding on the outer peripheral face on the outer peripheral face on edge, male joint location and edge, female joint location that to be provided with the mark that is used to be used protruding stupefied, with in public affairs, when female joint plugs together relatively, the relative position relation that shows block and non-return lock dog to the user, avoiding blind inserts public affairs, damage that female joint brought and the time of being wasted, in other embodiments, described mark is protruding stupefiedly also can use the mark coating, the mark cutting is replaced, perhaps under the situation of not considering the blind slotting influence that is brought, also can take out described mark protruding stupefied and/or coating and/or cutting.
In the above-described embodiments, the block of male and female joint by edge, male joint location and edge, female joint location cooperates and guarantees both in the axial direction spacing, thereby avoid that upper and lower steel pipe directly contacts when the relative plug-in mounting of male and female joint, the damage that steel tube place is brought, in other embodiments, the annular that also can remove in the pin and box sub is kept off along structure, and the male and female joint is fixed on the inwall of corresponding steel pipe.
In the above-described embodiments, block and non-return lock dog all have from after the trailing flank that all extends forward around clockwise hand of helix, with with commonly used spinner structure in to screw direction corresponding, raising is to the practicality of connected components, in other embodiments, the trailing flank of block and non-return lock dog also can all extend around counterclockwise hand of helix, and perhaps at least one in the trailing flank of block and non-return lock dog is the plane.
In the above-described embodiments, connected components is applicable in the occasion of upper and lower steel pipe butt joint and uses that in other embodiments, this also goes for connected components using in the occasion of mutual butt joint of horizontally extending adjacent two steel pipes.
In the above-described embodiments, the stationary positioned section of male joint and the female joint fixed part of female joint are the face of cylinder, to be used with the garden steel pipe, in other embodiments, the stationary positioned section of male joint and the female joint fixed part of female joint also can be many prismatics cylinders, such as common prismatic surfaces such as quadrangular face, six prismatic surfaces, to be used with steel pipe with prism-shaped endoporus.
In the above-described embodiments, the interior cover face of the positioning section of male joint and female joint is the corresponding fixing face of cylinder of fitting, in other embodiments, this face of cylinder also can be replaced with taper seat, thereby make that the outer peripheral face of positioning section of male joint is the external rotation curved surface, curved surface and the interior cover face of female joint circles round in being.
In the above-described embodiments, non-return lock dog and block are three, in other embodiments, non-return lock dog and block also can be one or two or more than three, concrete quantity determines according to the actual requirements.
The scaffold butt joint of the present utility model embodiment of female joint: as shown in Figures 1 to 4, the structure of female joint is identical with the structure of female joint in the foregoing description in the present embodiment, therefore repeats no more.
The scaffold butt joint of the present utility model embodiment of male joint: to shown in Figure 8, the structure of male joint is identical with the structure of male joint in the foregoing description in the present embodiment as Fig. 5, therefore repeats no more.
