Description
Technical field
The present invention relates to Hardware fitting field, more particularly to a kind of expansion pull bar.
Background technology
Expansion joint is compensation additional stress caused by temperature difference or mechanical oscillation, and is arranged on container casing or pipeline
A kind of flexible structure.Because it is used as a kind of elastic compensation element that can freely stretch, reliable operation, functional, structure
Compact the advantages of, have been widely used in departments such as chemical industry, metallurgy, nuclear energy.But, in cement industry, especially cement kiln is pre-
It is necessary to have the features such as high temperature resistant degree, small axially mounted size and big axial expansion amount for the expansion joint used on hot device.And it is current
The general expansion joint of in the market is substantially small wave height, the Ω shape metal bellows structures of the small pitch of waves, but such bellows
Manufacture craft limits the wall thickness of bellows, is also easy to produce swelling red sandstone unstability, and make such expansion joint fragile and damage
It is not easy-maintaining afterwards.
The content of the invention
The present invention solves the technical problem of a kind of expansion pull bar is provided, its is reasonable in design, simple in construction, solves
Pull bar is expanded the problem of discontinuity during balanced stress.
In order to solve the above technical problems, one aspect of the present invention is to provide a kind of expansion pull bar, including draw
Bar core, drag link sleeve and transition sleeve；The axle center of the drag link sleeve is provided with the central shaft hole for being used for installing the pull bar core；In described
Arbor hole is divided into mating cavity and directed cavity by insulating course；The pull bar core is installed in the central shaft hole；The pull bar core
One end be set with the transition sleeve；The transition sleeve is installed in the mating cavity in an interference fit；It is described
The end of pull bar core outside transition sleeve is provided with stop nut；The bottom of the drag link sleeve is additionally provided with the positioning hole for docking.
Preferably, the bottom of the pull bar core is additionally provided with the screw thread mouth for docking.
Preferably, the upper end of the drag link sleeve is additionally provided with the docking groove for clamping.
The beneficial effects of the invention are as follows：A kind of expansion pull bar is provided, its is simple in construction, reasonable in design, passes through the drawing of docking
Bar core realizes effective annexation, at the same between pull bar core and drag link sleeve by the attachment structure of transition come it is balanced should
Power, reaches work purpose.
Brief description of the drawings
Fig. 1 is a kind of structural representation for expanding pull bar of the present invention；
The mark of each part is as follows in accompanying drawing：1st, pull bar core；2nd, drag link sleeve；3rd, transition sleeve；4th, insulating course；5th, it is oriented to
Chamber；6th, stop nut；7th, docking groove；8th, positioning hole.
Embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
Accompanying drawing 1 is referred to, the embodiment of the present invention includes：
One kind expansion pull bar, including pull bar core 1, drag link sleeve 2 and transition sleeve 3；The axle center of the drag link sleeve, which is provided with, to be used for
The central shaft hole of the pull bar core 1 is installed；The central shaft hole is divided into mating cavity and directed cavity 5 by insulating course 4；The pull bar
Core is installed in the central shaft hole；One end of the pull bar core 1 is set with the transition sleeve 3；The transition sleeve 3 is with mistake
The mode of cooperation of being full of is installed in the mating cavity；The end of pull bar core 1 outside the transition sleeve 3 is provided with stop nut 6；Institute
The bottom for stating drag link sleeve 2 is additionally provided with positioning hole 8 for docking.The bottom of the pull bar core 1 is additionally provided with the screw thread for docking
Mouthful.The upper end of the drag link sleeve 2 is additionally provided with the docking groove 7 for clamping.During work, docked and connected accordingly by pull bar core 1
Binding structure, and installed between pull bar core 1 and drag link sleeve 2 by transition sleeve 3, the difference because stress point can be avoided
The problem of excessively being concentrated to the stress that pull bar core and drag link sleeve are caused.The expansion pull bar, its is simple in construction, reasonable in design, passes through
The pull bar core of docking realizes effective annexation, at the same between pull bar core and drag link sleeve by the attachment structure of transition come
Balanced stress, reaches work purpose.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
Equivalent structure or equivalent flow conversion that bright description is made, or directly or indirectly it is used in other related technology necks
Domain, is included within the scope of the present invention.
