Abstract
The utility model discloses a kind of circular thread bindiny mechanism being applied to prestressed anchor assembly or other anatomical connectivity, it comprises screw rod and nut, and the continuous thread thread form angle on screw rod and nut is equal, and both are that face coordinates when coordinating.The utility model has the advantage of and have employed circular thread, efficiently reduce on the one hand stress and concentrate and the probability that occurs microscopic crack; On the other hand, internal and external threads adopts face to coordinate, and time stressed in equipment running, both cooperations can be more and more tightr, thus efficiently avoid loosening generation; In addition, the internal thread of nut can adopt screw tap threaded shaping, also can adopt cutting forming; External thread of screw adopts the cold machining process of roll forming, and without the need to cutting, save material, manufacturing efficiency is high, effectively avoids low stress brittle fracture phenomenon; The cost of nut and screw rod is low, and manufacturing efficiency is high, is applicable to batch production.
Description
Technical field
The utility model relates to a kind of circular thread bindiny mechanism, is applied to the connection area of prestressed anchor assembly or other structures.
Background technique
Existing common screw thread has V thread screw, trapezoidal thread, square threaded form and buttress thread form.And at home on market, prestressing force basis, the screw thread on high-strength finish rolling deformed bar surface used as anchor pole is conventional trapezoidal thread, and screw thread is discontinuous, and this screw thread rebar surface when hot rolling is directly formed.Above-mentioned several screw thread has deficiency, namely has certain region of stress concentration, and have the reinforcing bar of these screw threads as anchor pole according to rolling, then, under long-term dither load, this kind of anchor pole has the risk of fracture.
Application number be 200910192231.6 patent discloses a kind of circular arc thread dental pattern, adopt technique for rolling or milling process forming thread, but this patent is only applicable to being tightly connected of thin metallic tubd, and is not suitable for the batch production of prestressed anchor subassembly product.
Model utility content
For the deficiencies in the prior art, the utility model provides a kind of circular thread bindiny mechanism.
The technical solution of the utility model is as follows:
A kind of circular thread bindiny mechanism, it comprises screw rod and nut, and screw rod and nut are provided with the internal and external threads cooperatively interacted; Internal and external threads is the continuous thread of face contact.
Continuous circular arc screw thread on described screw rod is outside thread, is connected to form successively by circular arc at the bottom of upper tooth tip circle arc, straightway and lower tooth; Continuous circular arc screw thread on described nut is internal thread, is connected to form successively by first circular arc, tangential straightway and crest.
Described straightway is tangent with circular arc at the bottom of upper tooth tip circle arc, lower tooth respectively, and upper radius of rounded crest is equal with lower radius of rounded root; Described tangential straightway and first circular arc tangent, described crest is plane.
Described external thread of screw is consistent with the thread form angle of nut inner thread.
The outside thread of screw rod can adopt roll forming, also can adopt cutting forming; The internal thread of nut can adopt screw tap threaded shaping, also can adopt cutting forming.
The positive progressive of the technical solution of the utility model is: adopt continuous circular arc screw thread, internal thread and outside thread are that face contacts, uniform force, effectively can reduce stress and concentrate and the probability that occurs microscopic crack; In addition, internal thread can be more and more tightr with the running of equipment with coordinating of outer spiral shell, effectively can avoid the generation loosened.In addition, nut inner thread adopts the threaded moulding process of screw tap; External thread of screw adopts the cold machining process of roll forming, and without the need to cutting, save material, manufacturing efficiency is high, avoids low stress brittle fracture phenomenon; The manufacturing efficiency of nut and screw rod is high, and cost is low, is applicable to producing in enormous quantities.

Embodiment
A kind of circular thread bindiny mechanism, as shown in Figure 1, it comprises screw rod 1 and nut 2, and screw rod 1 and nut 2 are provided with the internal and external threads cooperatively interacted; Internal and external threads is the continuous thread of face contact.
From Fig. 2 and Fig. 3, the continuous circular arc screw thread on described screw rod 1 is outside thread, is connected to form successively by circular arc 5 at the bottom of upper tooth tip circle arc 3, straightway 4 and lower tooth; Continuous circular arc screw thread on described nut 2 is internal thread, is connected to form successively by first circular arc 6, tangential straightway 7 and crest 8.
Described straightway 4 is tangent with circular arc 5 at the bottom of upper tooth tip circle arc 3, lower tooth respectively, and at the bottom of upper tooth tip circle arc 3 radius R and lower tooth, circular arc 5 radius R is equal; Described tangential straightway 7 is tangent with first circular arc 6, and described crest 8 is plane.
Described screw rod 1 outside thread is consistent with the thread form angle of nut 2 internal thread.Be that face coordinates when internal thread coordinates with outside thread.
