Abstract

The utility model relates to a one-way threaded connection structure. The one-way threaded connection structure comprises a bolt and a nut, wherein a threaded rod of the bolt is provided with threads, the nut is provided with threads corresponding to the threads on the threaded rod of the bolt, and the same unsymmetrical thread profiles are arranged on the threaded rod of the bolt and the nut respectively. The unsymmetrical design is adopted for the threaded connection profiles, when threaded connection has the requirement for directionality, only when the threads with the same profiles and in the same direction are selected, can mating parts be connected together, and the directionality requirement of threaded connection is met; in the one-off fastening process, the effect that screwing-in fastening force is small, and large force is needed for pulling-out in the reverse direction is achieved.

Description

A kind of unidirectional screw connection structure
Technical field
The utility model belongs to the technical field that is threaded, particularly a kind of unidirectional screw connection structure.
Background technique
At present, all thread profile that is threaded is and is arranged symmetrically with, and realizes fasteningly, fixing by screw thread, connects.But the position that is much threaded requires the power of thread failure to be greater than the fastening force when fastening, is threaded and need to has directivity, only allows one direction precession or back-out.The screw thread that this thread form is arranged symmetrically with can not meet the requirement of these special occasions.
Summary of the invention
The utility model is to solve the problem existing in known technology, has proposed the unidirectional screw connection structure that a kind of screw thread of can satisfying the demand has direction to require.
The technological scheme that the utility model is taked for the technical problem existing in solution known technology is:
A kind of unidirectional screw connection structure, comprise screw bolt and nut, on the screw rod of described bolt, be provided with screw thread, described nut is provided with the screw thread corresponding with screw thread on the screw rod of bolt, is provided with identical asymmetrical thread profile on the screw rod of described bolt and nut.
Described asymmetrical thread profile is asymmetric triangle V-thread.
Described asymmetrical thread profile is asymmetric trapezoidal V-thread.
Described asymmetrical thread profile is, the thread profile of precession direction is acute angle, and the thread profile that screws out direction is right angle or obtuse angle
The beneficial effects of the utility model are: the thread form that the utility model is threaded adopts asymmetric design, need to there is direction requirement during when being threaded, only select identical thread form and there is unidirectional screw thread, counterpart can be linked together, reach the directive requirement of the tool that is threaded, disposable fastening in, can accomplish to screw in fastening force less, and in the other direction pull-out needs effect more energetically.
Brief description of the drawings
Fig. 1 is the utility model theory structure schematic diagram;
Fig. 2 is embodiment's one structural representation;
Fig. 3 is embodiment's two structural representations.
In Fig. 1, Fig. 2 and Fig. 3,1. bolt, 2. nut.
Embodiment:
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of unidirectional screw connection structure, comprise bolt 1 and nut 2, on the screw rod of bolt 1, be provided with screw thread, nut 2 is provided with the screw thread corresponding with screw thread on the screw rod of bolt 1, is provided with identical asymmetrical thread profile on the screw rod of bolt 1 and nut 2, and asymmetrical thread profile is, the thread profile of precession direction (non-working surface) is acute angle, and the thread profile that screws out direction (working surface) is right angle or obtuse angle.Popular saying is exactly the V-thread with hangnail shape.
As shown in Figure 2, a kind of unidirectional screw connection structure comprises bolt 1 and nut 2 to embodiment one, is provided with asymmetric triangle V-thread on bolt 1 and nut 2.
As shown in Figure 3, a kind of unidirectional screw connection structure comprises bolt 1 and nut 2 to embodiment two, is provided with asymmetric trapezoidal V-thread on bolt 1 and nut 2.
This screw thread of the utility model can be widely used in the required screw of disposable fastening piece (as WOOD SCREWS, thread tapping etc.), screw rod is first-class.
The thread form that the utility model is threaded adopts asymmetric design, need to there is direction requirement during when being threaded, only select identical thread form and there is unidirectional screw thread, counterpart can be linked together, reach the directive requirement of the tool that is threaded, disposable fastening in, can accomplish to screw in fastening force less, and in the other direction pull-out needs effect more energetically.
Above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit, and those of ordinary skill in the field should be appreciated that still and can modify or part technical characteristics is equal to replacement the embodiment of model utility; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the technology of the utility model request protection.
