Description
Technical field
This utility model relates to five metals and connects accessory field, particularly relates to a kind of cylindrical connection.
Background technology
Along with the speed-raising of engineering construction, particularly the infrastructure project such as urban viaduct, building construction is increasing, is applied generally as the steel pipe scaffold in the process of construction of infrastructure.Commonly used in the building of steel pipe scaffold is the method for pipe fastener, takes fastener being fixedly linked as the two that can overlap i.e. up and down during steel pipe docking；Use this fastener not only to operate loaded down with trivial details, and easily allow upper and lower steel pipe can not centering like clockwork so that the steel tube poles on scaffold shows as eccentric connection.
Utility model content
This utility model is mainly solving the technical problems that provide a kind of cylindrical connection, and it is reasonable in design, simple in construction, solves docking structure complexity and connects unstable problem.
For solving above-mentioned technical problem, the technical scheme that this utility model uses is to provide a kind of cylindrical connection, including butt joint, mounting head and stem stem；Described butt joint is fixed in one end of described stem stem, and its other end fixes described mounting head；End face circle centre position in described mounting head is provided with the mating holes axially offered；The spring of coaxial position relation it is provided with in described mating holes；The rotary surface of mounting head is additionally provided with screw thread；Described butt joint is provided with the through hole radially offered；It is additionally provided with otic placode on the rotary surface of butt joint.
Preferably, described otic placode is provided with two, and two otic placodes are with the axle center of described butt joint as symmetrical centre；The spacing preiection of revolution it is additionally provided with on the surface of described mounting head.
The beneficial effects of the utility model are: provide a kind of cylindrical connection, improve the bearing capacity of steel pipe scaffold and strengthen the stability in the large of scaffold, and interfacing part simple in construction, easy to use, are substantially shorter the time setting up scaffold.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of cylindrical connection of this utility model；
Fig. 2 is the structure sectional view of cylindrical connection；
In accompanying drawing, the labelling of each parts is as follows: 1, butt joint；2, screw thread；3, stem stem；4, mating holes；5, spring；6, through hole；7, otic placode；8, spacing preiection.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made apparent clear and definite defining.
Referring to attached Fig. 1 and 2, this utility model embodiment includes:
A kind of cylindrical connection, including butt joint 1, mounting head and stem stem 3；Described butt joint 1 is fixed in one end of described stem stem 3, and its other end fixes described mounting head；End face circle centre position in described mounting head is provided with the mating holes 4 axially offered；The spring 5 of coaxial position relation it is provided with in described mating holes 4；The rotary surface of mounting head is additionally provided with screw thread 2；Described butt joint 1 is provided with the through hole 6 radially offered；Otic placode 7 it is additionally provided with on the rotary surface of butt joint 1.Described otic placode 7 is provided with two, and two otic placodes 7 are with the axle center of described butt joint as symmetrical centre；The spacing preiection 8 of revolution it is additionally provided with on the surface of described mounting head.Coordinated by outside, coordinate corresponding pin member to be flexibly connected in through hole 6, and add pretension dynamics by arranging spring 5 in mating holes 4 so that screw thread docking is more firm, will not produce axial interstitial vibration.This column interfacing part improves the bearing capacity of steel pipe scaffold and strengthens the stability in the large of scaffold, and interfacing part simple in construction, easy to use, is substantially shorter the time setting up scaffold.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in scope of patent protection of the present utility model.
