A kind of binding assembly for wall heat insulation material provided by the invention, the binding assembly for wall heat insulation material both can realize, from punching, can also realizing self-expanding; And there is butterfly cap nut structure make its fastening effect more obvious, its CONSTRUCTED SPECIFICATION also has many places to improve.Rely on the structure of the binding assembly for wall heat insulation material provided by the invention, can realize automatically holing on body of wall hole, reaming hole, automatically realize expansion fastening;
Analyze the above-mentioned binding assembly structure for wall heat insulation material known: first, in driving head modular construction, dop in driving head assembly is for connecting the installing hole of electric drill instrument, and after on the installing hole like this dop being arranged on electric drill instrument, dop will rotate as actuator; The hex-shaped recess of dop end coordinates with the first positioning spiro pit and jackscrew (i.e. industrial standard part), can realize fastening to hex wrench of dop; The outer-hexagonal of the little head end simultaneously in hex wrench coordinates with the hex-shaped recess of the screw in from hole expansion bolt assembly structure, and just can realize the rotary motion of driving screw; Namely driving order is followed successively by: electric drill instrument, dop, hex wrench, screw;
In from hole expansion bolt assembly structure, the structure of butterfly cap nut is core texture; Butterfly cap nut center is spherical hollow space, the top of spherical hollow space and bottom are equipped with through hole, and (head namely for above-mentioned screw passes, and head exceedes spherical hollow space), the inwall of spherical hollow space is also provided with internal thread (namely for realizing realizing being threaded to the external screw thread of the head of screw), and the external surface of spherical hollow space is also vertically provided with two and bores plate; Boring the bottom of plate is oblique tip bottom outstanding spherical hollow space (so more frame be conducive to boring plate carry out reaming to body of wall); Brill plate on butterfly cap nut is used for carrying out reaming to body of wall; Bore the top of plate also for having the modular construction (i.e. another oblique tip) at certain angle of inclination, this modular construction can be inserted on the slot of expansion bolt shell;
The inside of expansion bolt shell is cavity (i.e. cylindrical cavity), and be provided with two slots bottom it, top is provided with spline; Slot on above-mentioned expansion bolt shell coordinates with the top jack of the brill plate on butterfly cap nut, and the slot on expansion bolt shell just in time the bores plate oblique tip configuration in top with two on butterfly cap nut coordinates (namely draw-in groove coordinates); And then achieve the mechanical linkage effect of expansion bolt shell and butterfly cap nut; And the outer wall of expansion bolt shell also arranges external screw thread; Because expansion bolt cover top portion is provided with annular retaining ring; And annular retaining ring can serve as the effect of similar baffle plate, the bottom surface of its annular retaining ring is fitted in the end face of wall heat insulation material (such as: cystosepiment), and then the contact area of the annular retaining ring increased on expansion bolt shell and cystosepiment (namely enhancing contact), effectively can prevent coming off and preventing bookbinding from loosening of cystosepiment.In addition, annular retaining ring is also arranged multiple hollow out (it can be hole or become involute shape hollow out) and be convenient to cement and enter in hollow out, can the firm effect of annular retaining ring further on refinforced cement and expansion bolt shell after cement solidification.
In whole binding assembly structure, driving connector (such as: spline or other structures) on driving head shell in driving head modular construction coordinates with the top spline jack on the expansion bolt shell in from hole expansion bolt assembly structure, and for driving expansion bolt shell to rotate; In the middle part of driving head shell, reserved four the second positioning spiro pits are used for through jackscrew; Above-mentioned jackscrew also except through dop, also through the positioning spiro pit on driving head assembly and anti-reverse internal gear, and is connected as a single entity for fixing anti-reverse internal gear and driving head shell, realizes synchronously driving; Bearing for supporting the rotary motion of dop and driving head shell, and reduces friction; Its final driving order is followed successively by: electric drill instrument, dop, anti-reverse internal gear, driving head shell, expansion bolt shell, butterfly cap nut; (synchronous with electric drill instrument, dop, hex wrench, screw execution sequence);
In the bookbinding operation process carrying out wall heat insulation material, first electric drill instrument starts to rotate according to predetermined direction (such as: forward) start, drive dop rotates, dop drives hex wrench (and anti-reverse internal gear, driving head shell) synchronous rotary simultaneously, and final hex wrench drives screw to rotate forward (meanwhile driving head shell drive expansion bolt shell, butterfly cap nut synchronously rotate forward); In the process that above-mentioned drill bit rotates forward, screw and butterfly cap nut rotate forward and realize holing and reaming to wall insulated board; (the screw Main Function namely in drilling process from hole expansion bolt assembly is boring, and butterfly cap nut Main Function is reaming); After certain depth is crept in rotating forward, drive expansion bolt shell also to follow screw and butterfly cap nut and to pierce in wall heat insulation material certain depth, driving expansion bolt shell, just fastening with body of wall surrounding to achieve first time fastening; Electric drill instrument starts rotation of oppositely starting shooting subsequently, drive dop reversely rotates, dop drives hex wrench synchronous backward to rotate (under noting now anti-reverse internal gear effect simultaneously, dop can not drive driving head shell and the reversion of expansion bolt shell), finally only have hex wrench to drive screw reversion; Because screw is connected with butterfly cap nut tight thread, so screw also can drive butterfly cap nut to rotate; During such reverse rotation, screw will rotate up from bottom to top, because screw head is that to head on butterfly cap nut center after rotating up be spherical hollow space to flat structure with the through hole (namely the size of top through hole is less than screw flat structure) at top and screw threads for fastening is connected; (namely well-known, direction of rotation is consistent with hand of spiral will inevitably drive it to advance, and it can be driven on the contrary to retreat), therefore during reversion, screw creeps into no longer downwards but moves up; Like this at screw when rotating up, butterfly cap nut entirety can be driven to move upward; The expansion bolt shell ripping its top obviously after butterfly cap nut entirety moves upward makes it expand, and expansion bolt shell dilation is larger, reaches the object fastening to secondary; Can effectively thus play pressuring action, prevent bookbinding from loosening or coming off like this;
This mechanism boring the process later stage would have been completed penetrate fastening; Even if boring deflects, inner screw has also stretched in hole, and achieves expansion subsequently; There will not be because bit bore deflects in prior art, then plastic expansion bolt is thrown into boring increase, the problem that expansion declines.
Due to the expansion of butterfly cap nut and its both wings, namely to bore board diameter comparatively large, and can realize expanding largely realizes locking; Also expansion bolt shell farthest can be realized expanding in butterfly cap nut negative drawing process, its dilation is very large, and its degrees of expansion can not as the restriction of the screw diameter in conventional art.This structure is both stable also practical, can effectively play expansion pressuring action, prevents bookbinding from loosening or coming off.In sum, the binding assembly for wall heat insulation material both can realize, from punching, can also realizing self-expanding; And there is butterfly cap nut structure make its fastening effect more obvious, its CONSTRUCTED SPECIFICATION also has many places to improve;
