Below in conjunction with accompanying drawing and example, the utility model is further illustrated.
As shown in Figure 1: the one self-locking mechanical crab-bolt of autotomying, comprises that screw rod 101, nut 107, bullet pad 106, plain cushion 105, power transmits sleeve pipe 104, pipe-in-pipe autotomy ring 103, the two-way ring 102 of autotomying; Described screw rod 101 one end arrange hexagon head, and there is screw thread at middle part, and bottom has conical head and raised line is set; Described two-way ring 102 one end of autotomying have axial groove; And two-way ring 102 inclined-planes, two ends of autotomying arrange multiple from section, and the sheet head of autotomying arranges gear shape crop, root has radial groove; The described two-way ring 102 of autotomying is enclosed within screw rod 101 upper ends, and two-way ring 102 axial grooves of autotomying intersect and coordinate with screw rod 101 raised lines; Described pipe-in-pipe autotomy ring 103 lower ends have multiple from section, the sheet head of autotomying arranges gear shape crop, root has radial groove; The described pipe-in-pipe ring of autotomying 103 is enclosed within screw rod 101 upper ends, and intersects and coordinate with the two-way ring 102 of autotomying; Described power is transmitted sleeve pipe 104, plain cushion 105, bullet pad 106 and is enclosed within respectively on screw rod 101, and nut 107 is spun on screw rod 101 upper ends, and it is fastening, and this structure has the good base material of autotomying, self-locking effect, unstressedly engages with base material, and more piece is fastening, and bearing capacity is large.
In the specific implementation, row, as between cement ground and body of wall, dividing plate being installed, need to use the self locking type bidirectional fastening piece of autotomying, and two self locking type bidirectional fastening pieces of autotomying are set in the bottom of cement ground.
Use spanner nutting, the upper conical head of screw rod produces rotation incision and installs in next door and metope and concrete floor, because the self locking type bidirectional fastening piece of autotomying arranges plain cushion and bullet pad, makes between nut and screw rod relative fasteningly, is not prone to loosening.In the time dividing plate being installed the self locking type bidirectional fastening piece of autotomying is had to an outside pulling force, radially gear line is set owing to certainly cutting into slices, make two-way section certainly of autotomying on ring and body of wall produce friction and expand, make its lifting surface area increase, reach fixed effect.
Preferably, on described screw rod taper women's head-ornaments, four raised lines are set, and conical head avris arranges outside thread.In the time of screw rod and nut counterrotating, screw rod conical head outside thread produces rotation, and owing to be helical, what easily rotation is produced broken flows out with spiral chute, and the self locking type bidirectional fixed block of conveniently autotomying is cut concrete.
Preferably, described two-way autotomy ring inclined-plane, two ends from section and pipe-in-pipe autotomy ring lower end from section for circular; The described pipe-in-pipe ring of autotomying arranges radial teeth wheel crop with the two-way ring of autotomying from section surrounding, is conducive to cut concrete, is not easy to produce extruding base material, reaches unstressed engagement effect.
Preferably, describedly from section, radially gear line is set, in the time that fastening piece is locked metope, in the time being subject to outside power and drawing, the radial teeth of certainly cutting into slices wheel line plays increasing friction force effect, making to tighten and expand from section, has increased and has reached the effect of fastening.
Preferably, the described pipe-in-pipe ring lower end sheet head of autotomying of autotomying arranges chamfering, has increased the sharpness of certainly cutting into slices.When bidirectional fastening part is pulled outwardly be, certainly section easily and outside play friction, due to chamfering being set, make it to be more prone to cut in outside friction member, make it fastening.
Preferably, the described pipe-in-pipe ring one end of autotomying arranges slotted opening, describedly to the ring one end of autotomying, slotted opening is set, and autotomy ring and the two-way ring fluting autotomyed of pipe-in-pipe intersects cooperation.
Preferably, described pipe-in-pipe autotomy ring, two-way autotomy ring on circular groove is set respectively.
Preferably, described pipe-in-pipe autotomy ring, the two-way corresponding cross part of ring of autotomying, upper surface arranges guiding wedge face; Described pipe-in-pipe autotomy ring, two-way autotomy ring on circular groove is set respectively.In the time of bidirectional fastening part incision metope, guiding wedge face and metope produce friction, and due to circular groove portion, wall is thin herein, easily curves, favourable from section distending.
When use, in the time of screw rod and nut counterrotating, screw rod conical head arranges raised line, it is stuck in fraising, cause the ring of respectively autotomying to produce spiral motion incision concrete, radial teeth wheel crop is set owing to certainly cutting into slices, be conducive to cut concrete substrate, be not easy to produce extruding base material, reach unstressed engagement effect; Autotomy ring, the two-way corresponding cross part of ring of autotomying of described pipe-in-pipe arranges guiding wedge face, and in the time increased by pulling capacity, autotomy ring, the two-way ring circular groove portion of autotomying of described pipe-in-pipe rubbed, and easily curves, favourable from the distending of cutting into slices.From section radial teeth wheel line, play increasing friction force, make respectively to cut from ring and strengthen and expand, increase lifting surface area, reach larger bearing capacity.Due to bidirectional fastening, cause screw rod can not produce axial float displacement, reach self-locking effect.
Applied range, is applicable to various intensity concrete, can be used for various fixing, simple in structure, has good wear-resisting, corrosion resistance, and heat-resisting quantity is better than chemistry to fastening piece; Convenient, two meters of offering are installed, self-locking locking key effect, effect is oppositely installed as two pre-embedded bolts, and anchoring is without swelling stress, is applicable to little back gauge, little spacing is installed fixing.Superhigh strength, stable performance, long service life.Pulling capacity is large, antifatigue, anti-vibration, safe and reliable, produces mechanical lock bonding effect by applying moment of torsion, reaches the effect that expands the end, and it is anchored in base material safely and reliably, plays the effect of high-strength anchoring.The end system of autotomying, can not need the special basic skill or training's of cutting tool, simple operation, reaming fast regular, can be safely, convenient dismounting.
The utility model one self-locking mechanical crab-bolt of autotomying, the ring axial groove of autotomying intersects with screw rod raised line, and this structure has the good base material of autotomying, unstressedly engages with base material, bidirectional fastening, cause screw rod can not produce axial float displacement, reach self-locking effect, bearing capacity is large.
Be to be understood that to be, for those of ordinary skills, can improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
