Abstract
The utility model provides a section of jurisdiction fastening bolt mutually supports with the nut, its characterized in that: including bolt body and threaded rod, the bolt body is fixed at the threaded rod top, the threaded rod top is equipped with the top screw thread, and the threaded rod bottom is equipped with the bottom screw thread that is connected with the nut, and bolt body bottom inwards is equipped with the internal thread hole corresponding with the top screw thread, hexagonal shrinkage pool in being equipped with in the threaded rod top, and interior hexagonal shrinkage pool embeds there is powerful spring. The utility model provides a section of jurisdiction fastening bolt can avoid using for a long time and produce not hard up hidden danger, stops the possibility that petroleum pipelines revealed, and convenient to detach.
Description
Technical field
The utility model belongs to pipelines and petrochemical pipelines apparatus field, particularly a kind of section of jurisdiction clamping bolt.
Background technique
China is the country of a heavy dependence oil, the annual construction all will carrying out extensive pipelines and petrochemical pipelines, existing pipelines and petrochemical pipelines forms integral hermetic by bolt or spot welding, spot welding difficulty is comparatively large, and form difficult point to later period maintenance maintenance, bolts assemblies is simple, but existing bolt can produce loosening for a long time, easily cause the leakage of pipelines and petrochemical pipelines, and nut is once after getting rusty, is difficult to dismounting.
Model utility content
For solving defect of the prior art, the utility model provides a kind of section of jurisdiction clamping bolt, and this device can avoid long-time use to produce loosening hidden danger, stops the possibility that pipelines and petrochemical pipelines is revealed, and is convenient to dismounting.
Technological scheme:
A kind of section of jurisdiction clamping bolt, cooperatively interacts with nut, comprises bolt body and threaded stem; Described bolt body is fixed on described threaded stem top; Described threaded stem top is provided with screw top, the bottom thread be connected with described nut is provided with bottom described threaded stem, the interior threaded hole corresponding with described screw top is inwardly provided with bottom described bolt body, be provided with interior hexagonal shrinkage pool in described threaded stem top, described interior hexagonal shrinkage pool is built-in with brute spring.
Described bolt body lower surface is distributed with 4-6 projection.
Described bolt body is six column structures.
Technique effect:
The utility model provides a kind of section of jurisdiction clamping bolt, and compared to the prior art, the utility model has following beneficial effect:
Described bolt body is fixed on described threaded stem top by thread engagement, when nut once get rusty, namely the mode by demounting bolt body is dismantled, simple and convenient, if threaded stem is in the tapped hole of fastening piece, then by utilizing the internal hexagonal shrinkage pool of hexagon wrench instrument to carry out rotary manipulation after demounting bolt body; Simultaneously, in hexagonal shrinkage pool, built-in brute spring can promote the anti-loosening property of bolt body.The projection that bolt body lower surface is arranged also further can increase frictional force, prevents getting loose of bolt body.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of section of jurisdiction clamping bolt in the utility model;
Fig. 2 is the structural representation of bolt body in Fig. 1.
In figure, each label example is as follows:
Hexagonal shrinkage pool, 7-nut, 8-interior threaded hole, 9-projection in 1-bolt body, 2-brute spring, 3-threaded stem, 4-screw top, 5-bottom thread, 6-.
Embodiment
Fig. 1 is the structural representation of a kind of section of jurisdiction clamping bolt in the utility model; Fig. 2 is the structural representation of bolt body in Fig. 1, and shown in Fig. 1 and Fig. 2, a kind of section of jurisdiction disclosed in the utility model clamping bolt, cooperatively interacts on fastening piece with nut 7, comprises bolt body 1 and threaded stem 3; Bolt body 1 is fixed on threaded stem 3 top; Threaded stem 3 top is provided with screw top 4, is provided with the bottom thread 5 be connected with nut 7 bottom threaded stem 3, is inwardly provided with the interior threaded hole 8 corresponding with screw top 4 bottom bolt body 1, makes bolt body 1 be fixed on threaded stem 3 top by thread engagement.When nut once get rusty, the mode namely by demounting bolt body is dismantled.
Interior hexagonal shrinkage pool 6 is provided with, when threaded stem 3 is in the tapped hole of fastening piece, then by utilizing the internal hexagonal shrinkage pool 6 of hexagon wrench instrument to carry out rotary manipulation after demounting bolt body 1 in threaded stem 3 top; Interior hexagonal shrinkage pool 6 is built-in with brute spring 2, can promote the anti-loosening property of bolt body.Bolt body 1 lower surface is distributed with 4-6 projection 9, and projection 9 further can increase frictional force, prevents getting loose of bolt body 1.In the present embodiment, preferred projection 9 quantity is 6, is evenly distributed on the lower surface of bolt body 1.
Bolt body 1 is six column structures.Conveniently dismantled by Wrench, structure is simple, convenient operation.
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
