Description
Technical field
The utility model belongs to building structure technology field, is related to a kind of lead screw fulcrum bearing of fine-tuning installation steel construction.
Background technology
Steel construction is the structure being mainly made of steel material, is one of main building construction types.Structure mainly by
The components such as girder steel, steel column, steel truss made of shaped steel and steel plate etc. form, generally use weld seam, spiral shell between each component or component
Bolt or rivet interlacement.Because its dead weight is lighter, and easy construction, it is widely used in the fields such as large-sized workshop, venue, Super High.
When specifically being built using steel construction for some, such as workshop and greenhouse, it is needing top above
Lid is installed to a very accurately height, however the prior art accurately can not be installed and be built.
A kind of existing steel structural form solves asking for hard-cover control installation using the good quadrangle principle of feed screw nut pair
Topic, however the characteristics of according to the structure needs a kind of special lead screw mounting base for coordinating lead screw to realize function.
Utility model content
In view of problem pointed in background technology, the technical problem to be solved by the utility model is to provide one kind can
The lead screw fulcrum bearing of fine tuning installation steel construction.
Technical solutions of the utility model are as follows：A kind of lead screw fulcrum bearing of fine-tuning installation steel construction, including fulcrum bearing bottom
Plate, the fulcrum bearing bottom plate are provided with feed screw nut, and the feed screw nut is inlaid in by spline in the fulcrum bearing bottom plate
Portion, and it is connected to by the through-hole of the feed screw nut both sides of the fulcrum bearing bottom plate, the bearing by the feed screw nut
Setting is there are two support arm articulated slab on seat bottom plate, and two support arm articulated slabs are end-to-end to be arranged side by side, and each support arm
Hinged through-hole is both provided on articulated slab.
Further, each support arm articulated slab is both provided with embedded ring in the plate face of the feed screw nut side
Slot, and the embedded annular groove is in arranged in concentric circles with the corresponding hinged through-hole.
Further, the periphery of the feed screw nut is provided with spline tooth, accordingly, spiral shell is provided on the fulcrum bearing bottom plate
The periphery of female inlaid hole, the nut inlaid hole is provided with spline.
Further, four angle chamferings of the fulcrum bearing bottom plate.
Advantageous effect：The utility model is novel, reasonable design and is easy to use, for installation into the middle part of lead screw,
Support arm is hingedly installed by support arm articulated slab simultaneously, compact-sized, intensity is good, using reliable.
Description of the drawings
Fig. 1 is the utility model positive structure diagram.
Fig. 2 is the utility model side structure schematic view.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and examples：
A kind of lead screw fulcrum bearing of fine-tuning installation steel construction as depicted in figs. 1 and 2, including fulcrum bearing bottom plate 1, bearing
Four angle chamferings of seat bottom plate 1.Fulcrum bearing bottom plate 1 is provided with feed screw nut 2, and feed screw nut 2 is inlaid in fulcrum bearing by spline
The middle part of bottom plate 1, and by the both sides of the through-hole of feed screw nut 2 connection fulcrum bearing bottom plate 1, the periphery of feed screw nut 2 is provided with
Spline tooth 2a is accordingly provided with nut inlaid hole 1a on fulcrum bearing bottom plate 1, the periphery of nut inlaid hole 1a is provided with flower
Keyway 1aa.There are two support arm articulated slab 3, two support arm articulated slabs 3 are end-to-end for setting on the fulcrum bearing bottom plate 1 on 2 side of feed screw nut
It is arranged side by side, and hinged through-hole 3a is both provided on each support arm articulated slab 3.Each support arm articulated slab 3 is close to feed screw nut 2 one
Embedded annular groove 3b is both provided in the plate face of side, and it is in arranged in concentric circles to be embedded in annular groove 3b with corresponding hinged through-hole 3a.
The principle of the use of the new type is as follows：
Mounting body of the fulcrum bearing bottom plate 1 as the utility model for installing each auxiliary function component, and is used for
It will be in integral installation to corresponding steel construction.Feed screw nut 2 is used for coordinating with lead screw when in use, two support arm articulated slabs 3
One of them is used for hingedly installing corresponding upper branch arm, another is used for hingedly installing corresponding lower branch arm.Feed screw nut's 2 is outer
Spline tooth is arranged in week, and the nut inlaid hole 1a of spline 1aa is provided on fulcrum bearing bottom plate 1, and can so be convenient for will be practical
The feed screw nut 2 being used cooperatively with lead screw renew.
The preferred embodiment of the utility model described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality on the basis of existing technology according to the design of the utility model in domain
Available technical solution is tested, it all should be in the protection domain being defined in the patent claims.
