Description
Technical field
The invention belongs to building construction formwork fixed equipment technical field, specifically a kind of supercharging bispin lock core Nut pole.
Background technique
Screw rod is applied widely in actual life, when nut internal fixtion bearing material pressure exceedes thread line strength, just there will be a stroke button nut and fall phenomenon, and this phenomenon is also various accident root places, in order to avoid this accident to occur better, general people take to weld together to guarantee safety with electric weld handle nut and screw rod, cut open with oxygen welding when dismantling again, expensive effort inefficiency, and safety is not completely guaranteed yet.
In work progress, welding is the screwing force in order to increase nut, and in real screw field uses, nut is twisted and is not tightly twisted less than desired pressure, pitch mainly due to button silk screw thread is too large, and when being critical to a certain extent, just that fraction poor a bit, does not firmly too littlely reach tightness, therefore and all kinds of accident occurs also is innumerable firmly the too large button silk that destroys again is drawn and has been detained, and bad grasp is perplexed so far always.
Summary of the invention
In order to solve screw rod and nut screw connection in existing template construction, loosely, the problem of easily threading off, provides a kind of supercharging bispin lock core Nut pole in the present invention.
The present invention takes following technological scheme: a kind of supercharging bispin lock core Nut pole, and comprise screw rod, screw rod two ends are provided with screw thread, and on screw thread, cover has nut, the end at described screw rod two ends is provided with the taper circular hole arranged along screw rod radial direction, and all sides of taper circular hole have some dilatation joints be disposed radially, and be provided with conical screw in taper circular hole, conical screw afterbody has spill plate hole, described nut comprises the inner nut I be enclosed within screw rod, interlayer screw thread, outer nut I and antislip ring, inner nut I inner ring is provided with the internal thread that can be connected with screw flight, outside inner nut I, cover has interlayer screw thread, interlayer screw thread is hollow cylinder structure, the hollow shape for agreeing with inner nut I inside interlayer screw thread, be cylindrical outside interlayer screw thread, the outside of interlayer screw thread is provided with outside thread, outside interlayer screw thread, cover has the outer nut I that can be threaded with outer screw thread, the antislip ring that can be enclosed within screw rod is provided with on the downside of outer nut I, it is smooth surface on the upside of antislip ring, anti-slip veins is provided with on the downside of antislip ring.
Inside inner nut I, the pitch of internal thread is greater than externally threaded pitch outside interlayer screw thread.
The pitch of internal thread and the ratio of externally threaded pitch are at 1:1 ~ 2:1 within the scope of this.
Described nut can also use following this nut, nut comprises inner nut II, outer nut II and intubate, inner nut II is loop configuration, internal thread is provided with inside inner nut II, outside thread is provided with outside inner nut II, on inner nut II, cover has the outer nut II be threaded with it, and inner nut II and outer nut II is provided with mutually corresponding recess hole, is inserted with intubate in recess hole.
Inside inner nut II, the pitch of internal thread is greater than the externally threaded pitch in outside.
The pitch of internal thread and the ratio of externally threaded pitch are at 1:1 ~ 2:1 within the scope of this.
During use, screw rod is through fixture (template), after bringing nut screwing clamping into, screw rod one or both ends inner conical screw is tightened again with allen wrench, screw rod one or both ends screw head is expanded blow, guarantee nut to bear suddenly huge drag exceed screw thread bear pressure time, and there will not be nut to draw suddenly button to come off screw rod generation major accident.
Compared with prior art, when the present invention uses, screw rod is through fixture, after bringing nut screwing clamping into, screw rod one or both ends inner conical screw is tightened again with allen wrench, screw rod one or both ends screw head is expanded blow, guarantee nut to bear suddenly huge drag exceed screw thread bear pressure time, and there will not be nut to draw suddenly button to come off screw rod generation major accident.

Embodiment
As shown in Figure 1, a kind of supercharging bispin lock core Nut pole, comprise screw rod 5, screw rod 5 two ends are provided with screw thread, and on screw thread, cover has nut 4; The end at described screw rod 5 two ends is provided with the taper circular hole 2 arranged along screw rod radial direction, and taper circular hole 2 weeks sides have some dilatation joints 3 be disposed radially, and be provided with conical screw 1 in taper circular hole 2, conical screw 1 afterbody has spill plate hole; As shown in Figure 2,3, described nut 4 adopts double-rotary anti-drop supercharging nut, comprise the inner nut I4.11 be enclosed within screw rod, interlayer screw thread 4.12, outer nut I4.13 and antislip ring 4.14, inner nut I4.11 inner ring is provided with the internal thread that can be connected with screw flight, outside inner nut I4.11, cover has interlayer screw thread 4.12, interlayer screw thread 4.12 is hollow cylinder structure, the hollow shape for agreeing with inner nut I4.11 inside interlayer screw thread 4.12, be cylindrical outside interlayer screw thread 4.12, the outside of interlayer screw thread 4.12 is provided with outside thread 4.15(and sees Fig. 4,5).Outside interlayer screw thread 4.12, cover has the outer nut I4.13 that can be threaded with outer screw thread, and being provided with the antislip ring 4.14 that can be enclosed within screw rod on the downside of outer nut I4.13, is smooth surface on the upside of antislip ring 4.14, is provided with anti-slip veins 4.16(and sees Fig. 6 on the downside of antislip ring 4.14).
Inside inner nut I4.11, the pitch of internal thread is greater than the pitch of outside thread 4.15 outside interlayer screw thread 4.12.
The pitch of internal thread and the ratio of externally threaded pitch are at 1:1 ~ 2:1 within the scope of this.
Utilize closely-pitched pitch little, be elevated a little little, increase pressure, make nut more fastening.The one-sided smooth that antislip ring 4 contacts with nut, reduce resistance, that therefore can twist is nearer.Another side is provided with anti-slip veins, contacts, increasing friction force with other body surfaces, ensures that nut is more firm.
Described nut can also use supercharging bispin lock core nut, as shown in Figure 7,8, nut comprises inner nut II4.21, outer nut II4.22 and intubate 4.23, inner nut II4.21 is loop configuration, be provided with internal thread inside inner nut II4.21, be provided with outside thread outside inner nut II4.21, on inner nut II4.21, cover has the outer nut II4.22 be threaded with it, inner nut II4.21 and outer nut II4.22 is provided with mutually corresponding recess hole, is inserted with intubate 4.23 in recess hole.
Inside inner nut II4.21, the pitch of internal thread is greater than the externally threaded pitch in outside.
The pitch of internal thread and the ratio of externally threaded pitch are at 1:1 ~ 2:1 within the scope of this.
During use, first by double-rotary anti-drop supercharging nut screwing clamping on screw rod, then the intubate in recess hole is extracted, now continues to tighten outer nut.Because the pitch of thread between outer nut and inner nut is little, and fine thread is twisted the constant pressure that is critical of power and can be increased principle, increases original nut several times pressure and makes fixture more fastening.
