Abstract
It is disclosed by the utility model to belong to pre-buried channel flow technical field of construction in shield piece, specially a kind of steady torque power fastening nut, including fastening nut, bolt apertures are offered in the inner cavity of the fastening nut, the top of the fastening nut is integrally formed with thin neck, and the narrow neck part is in the surface of bolt apertures, the top of the thin neck is integrally formed with force section, this is practical by being provided with principle thin neck similar with plastic seal plastic bottle closure, when being initially spirally connected fixed, torsional forces is less than the receiving pressure of thin neck, play the effect for driving fastening nut rotation fixed, after the completion of fixation, torsional forces constantly rises with rotation, when the torsional forces of application is more than design value, thin neck fracture, to reach the control to torque magnitude, avoid the occurrence of torsion it is excessive or it is too small cause influence pouring molding shield piece not The problem of easily using.
Description
Technical field
The utility model relates to pre-buried channel flow technical field of construction in shield piece, specially a kind of steady torque power fastens spiral shell
It is female.
Background technique
Installation electromechanical equipment gradually replaces post-anchoring technology by pre-buried channel flow technology in modern subway tunnel, and pre-buried channel flow pours
It builds in shield piece, conduit accurate positioning is required during pouring solid, accuracy is high.Plastic nut in work progress due to
Torsion is excessive to will cause the tripping of nut stripped thread, and torsion is small, will cause shield piece and covers slurry, influence using and beauty.
Utility model content
The purpose of this utility model is to provide a kind of steady torque power fastening nuts, to solve to mention in above-mentioned background technique
The problem of nut torsion out is not easily controlled.
To achieve the above object, the utility model provides the following technical solutions: a kind of steady torque power fastening nut, including
Fastening nut, offers bolt apertures in the inner cavity of the fastening nut, the top of the fastening nut integrally formed with thin neck,
And the narrow neck part, in the surface of bolt apertures, the top of the thin neck is integrally formed with force section.
Preferably, the thin neck is the thin neck of plastics system.
Preferably, the thin neck is cylindrical thin neck, and offers torsion adjusting in the inner cavity of the thin neck and open
Hole.
Preferably, the fastening nut is T-nut.
Compared with prior art, the utility model has the beneficial effects that this is practical by being provided with principle and plastic seal
The similar thin neck of plastic bottle closure, when being initially spirally connected fixed, torsional forces is less than the receiving pressure of thin neck, plays drive fastening
The fixed effect of nut rotation, after the completion of fixation, torsional forces constantly rises with rotation, is more than design in the torsional forces of application
When value, it is excessive or too small cause to influence to pour to build up to avoid the occurrence of torsion to reach the control to torque magnitude for the fracture of thin neck
The shield piece of type problem not easy to use.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the top view of the utility model Fig. 1；
Fig. 3 is the utility model nut assembling structure schematic diagram.
In figure: 1 fastening nut, 2 bolt apertures, 3 thin necks, 4 force sections.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of steady torque power fastening nut, including it is tight
Gu nut 1 offers bolt apertures 2 in the inner cavity of the fastening nut 1, realizes the use of normal fastening nut 1, the fastening
It bears the torsional forces upper limit by thin neck 3 and determines to be born with regard to nut 1 integrally formed with thin neck 3 in the top of nut 1
Torsional forces, and the thin neck 3 is located at the surface of bolt apertures 2, and the top of the thin neck 3 is integrally formed with force section 4.
Wherein, the thin neck 3 is the thin neck of plastics system, carries out processing use by the material of the easy fractures such as plastics, just
Can reach the torsional forces of fracture when realizing artificial use, the thin neck 3 is cylindrical thin neck, and the thin neck 3
Torsion is offered in inner cavity and adjusts aperture, is used for bolt there are certain activity space, is guaranteed to pre-buried channel flow mold thickness
Carried out when variation using, and by torsion adjust aperture diameter adjustment, can intuitively change the torsional forces size that can be carried,
The fastening nut 1 is T-nut, is matched convenient for adjusting with the length of bolt, the length for avoiding bolt from having more excessively influences
Fixed effect.
Working principle: it is originally practical to be poured in mold in shield piece, by the mold of preformed groove by pouring the fixation in mold
Fastening nut 1 is fixed on fixing bolt by bolt after bolt-through reserves groove mould, is then continued by force section 4
Application dynamics, by constantly increasing torsional forces, when torsional forces is more than the design torque power of thin neck 3, thin neck 3 is broken, complete
The fixation of pairs of fastening nut 1, it is ensured that the range of torsional forces at this time avoids the occurrence of the excessive or too small problem of torsional forces.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
