Abstract
The utility model discloses a kind of nut for section bar connection and section bar component, wherein nut comprises main body, and a vertical tapped hole is run through along the center of main body, main body relative two vertically surface to central concave, form dovetail shaped groove, groove is that axle is symmetrical with tapped hole.The utility model can effectively avoid nut to occur relative to section bar phenomenons such as sliding, crooked, thus ensures the connection precision between section bar and intensity, and use simple, quick, structure is simple, is easy to practical.
Description
Technical field
The utility model relates to a kind of fastening piece, especially relates to a kind of nut.
Background technique
Section bar is the bar structural section with certain section shape and size, it is one of large kind of steel four, be widely used in building, the fields such as manufacture, can carry out between multiple section bar combining to form section bar component, play support, the effects such as reinforcing, prior art medium section is generally connected by fastening piece, as hexagon nut snapped in the groove of place's Surface of profile, bolt passes from another section bar and screws in nut, thus two place's section bars are connected as one, but plain nut is easy in use slides in groove, crooked, thus cause getting loose between itself and bolt, affect the connection effect between section bar, prior art can not well address this problem.
Model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of nut connected for section bar, can effectively avoid nut to occur relative to section bar phenomenons such as sliding, crooked, thus connection precision between guarantee section bar and intensity, use simple, quick, structure is simple, is easy to practical.
The utility model solves the technological scheme that its technical problem adopts:
For the nut that section bar connects, comprise main body, a vertical tapped hole is run through along the center of main body, main body relative two vertically surface is to central concave, form dovetail shaped groove, groove is that axle is symmetrical with tapped hole.
As the further improved procedure of such scheme, between groove and an adjacent vertical surface, place, form circular arc camber, and this circular arc camber be positioned on different groove take tapped hole as axle is centrosymmetric.
A kind of section bar component, comprise section bar and bolt, section bar has connecting surface, which is provided with dovetail groove, also comprise above-mentioned nut, the section bar at least two places is fitted by connecting surface, and forms cavity between dovetail groove, nut is fastened in this cavity, and bolt is spirally connected with nut through after one-sided section bar.
As the further improved procedure of such scheme, comprise link, link comprises a diapire, the center of diapire has a via hole, both sides have outstanding sidewall, link is abutted with the bottom of dovetail groove by this sidewall, and bolt is spirally connected with nut after passing via hole and the section bar that abuts with this link.
As the further improved procedure of such scheme, the bottom of sidewall is provided with the undertaking wall of level.
The beneficial effects of the utility model are:
Nut effectively can be avoided to occur relative to section bar phenomenons such as sliding, crooked, thus ensure the connection precision between section bar and intensity, use simple, quick, structure is simple, is easy to practical.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the axonometric drawing of a nut embodiment;
Fig. 2 is the axonometric drawing of a section bar component embodiment;
Fig. 3 is the side view of a section bar component embodiment;
Fig. 4 is the exploded view (hiding section bar) of a section bar component embodiment;
Fig. 5 is the axonometric drawing of a link embodiment.
Embodiment
Be clearly and completely described below with reference to embodiment and the accompanying drawing technique effect to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, scheme and effect fully.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
It should be noted that, if no special instructions, when a certain feature is called as " fixing ", " connection " in another feature, it can directly be fixed, be connected in another feature, also indirectly can fix, be connected in another feature.In addition, it is only relative to the mutual alignment relation of each constituent element of the utility model in accompanying drawing that the upper and lower, left and right used in the utility model etc. describe.
In addition, unless otherwise defined, all technology used herein are identical with the implication that those skilled in the art understand usually with scientific terminology.The term used in specification is herein to describe specific embodiment, instead of in order to limit the present invention.Term as used herein " and/or " comprise the arbitrary combination of one or more relevant Listed Items.
With reference to Fig. 1, show the schematic diagram of the utility model nut embodiment, comprise a main body, preferably, main body is approximately rectangle, which is provided with upper surface 11 and lower surface 12, one tapped hole 13 is run through along the center of main body, and forms opening on upper and lower surface.To central concave, form dovetail shaped groove 14, this groove is the symmetrical distribution of axle with tapped hole 13 on two vertical surfaces (as surface, left and right) relative in main body.
Preferably, between groove 14 and an adjacent vertical surface, place, form circular arc camber 15, avoiding structure when rotating as nut, be positioned at this circular arc camber on different groove with tapped hole 13 for axle is centrosymmetric.
The invention also discloses a kind of section bar component, with reference to Fig. 2 to Fig. 4, comprise section bar 2, bolt 3 and above-mentioned nut 1, wherein, section bar 2 has connecting surface, described connecting surface is provided with dovetail groove 21, the section bar at least two places is fitted by connecting surface, thus cavity is formed between dovetail groove 21, nut 1 is fastened in this cavity, and the projection be made up of the opening of dovetail groove 21 is accommodated in the groove 14 of nut 1, two place's section bars are connected as one, bolt, through after one-sided section bar, is spirally connected with nut 1, thus carries out fastening to section bar.
Preferably, also include link 4, with reference to Fig. 5, comprise a diapire 41, its center is provided with via hole 42, and both sides are provided with outstanding sidewall 43, link 4 is abutted with the bottom of dovetail groove 21 by this sidewall, after bolt 3 passes via hole 42 and the link 4 that abuts with this via hole, then screws in nut 1.Link by with the abutting of section bar inwall, can limit the slip of nut, its diapire is unsettled relative to section bar simultaneously, thus makes it have certain elastic deformation amount, is convenient to the connection of bolts and nuts.
Further, the bottom of sidewall 43 is provided with the undertaking wall 44 of level, and it can increase the area of contact between link and section bar on the one hand, and another fermentation also can increase the intensity of sidewall.
In the actual using process of nut, it first vertically can put into cavity, and then towards having the side rotating nut of circular arc camber, because curved surface can avoid nut and section bar to interfere, thus nut can be made finally horizontal in cavity, now, another side of groove 14 and the internal surface of cavity support, nut is limited in current state, prevents it from further rotating.
More than that better enforcement of the present utility model is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent distortion or replacement are all included in the application's claim limited range.
