Abstract
The invention discloses a cylindrical connecting piece and relates to the field of hardware connection fittings. The cylindrical connecting piece comprises a butt joint, an installation head and a core column. One end of the core column is fixed to the butt joint, and the other end of the core column is fixed to the installation head. A matching hole formed in the axial direction is formed in the circle center of the end face of the installation head. A spring coaxial with the matching hole is arranged in the matching hole. A thread is further arranged on the rotary surface of the installation head. A through hole formed in the radial direction is formed in the butt joint. A lug plate is further arranged on the rotary surface of the butt joint. The cylindrical butt-joint piece improves the bearing capacity of a steel pipe scaffold, enhances the overall stability of the scaffold, and is simple in structure, convenient to use and capable of greatly shortening the scaffold erection time.
Description
Technical field
The present invention relates to five metals and connect accessory field, particularly relate 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.
Summary of the invention
The technical problem that present invention mainly solves is to 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 the present invention 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 invention has the beneficial effects as follows: a kind of cylindrical connection is provided, improve the bearing capacity of steel pipe scaffold and strengthen the resistance to overturning of scaffold, and interfacing part simple in construction, easy to use, it is substantially shorter the time setting up scaffold.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of cylindrical connection of the present invention；
Fig. 2 is the structure sectional view of cylindrical connection；
In accompanying drawing, the mark 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 presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
Referring to attached Fig. 1 and 2, the embodiment of the present invention 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 resistance to overturning of scaffold, and interfacing part simple in construction, easy to use, is substantially shorter the time setting up scaffold.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention content 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 the scope of patent protection of the present invention.
