Abstract
The utility model discloses a kind of novel screw, comprise rivet nut, the end of described rivet nut is provided with booster, and this booster comprises the sleeve being fixedly installed on rivet nut end and the flexible rod be set in sleeve, and the medial axis of described sleeve is mutually vertical with the medial axis of described rivet nut.The utility model can carry out light dismounting in the situation without instrument to screw by the booster carried, and after completing dismounting or installment work, booster can reduced volume, avoids mutually disturbing with around accessory.
Description
Technical field
The utility model relates to a kind of screw, particularly relates to a kind of screw easy for removal and installation.
Background technique
the installation and removal of screw are generally come by screw-driver, are difficult to free-handly complete installation or removal work when not having screw-driver, and in addition, the mating groove of the tip of screw of different model is different, need to adopt corresponding screw-driver could coupling mutually.
Model utility content
the technical problems to be solved in the utility model is to provide a kind of novel screw, can carry out light dismounting by booster in the situation without instrument to screw, and after completing dismounting or installment work, booster can reduced volume, avoids mutually disturbing with around accessory.
To achieve these goals, technical solution adopted in the utility model is: a kind of novel screw, comprise rivet nut, the end of described rivet nut is provided with booster, this booster comprises the sleeve being fixedly installed on rivet nut end and the flexible rod be set in sleeve, and the medial axis of described sleeve is mutually vertical with the medial axis of described rivet nut.
As a kind of optimal technical scheme of the present utility model, the transverse section of described sleeve is the outer square structure of inner circle.
As a kind of optimal technical scheme of the present utility model, described sleeve lining be provided with position limit cycle, the outer wall of described flexible rod is provided with limited ring, and flexible rod end is provided with draw ring.
As a kind of optimal technical scheme of the present utility model, the length of described sleeve equals the diameter of described rivet nut, and the length of described flexible rod is less than the length of described sleeve.
As a kind of optimal technical scheme of the present utility model, also comprise the sealing cover with the port match of described sleeve in its structure, sealing cover is fastened and connected with described sleeve or is threaded.
The beneficial effect adopting technique scheme to produce is: the utility model can carry out light dismounting in the situation without instrument to screw by the booster carried, and booster can reduced volume after completing dismounting or installment work, avoid mutually disturbing with around accessory.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is longitudinal section of the present utility model.
Fig. 2 is the partial enlarged drawing of part A in Fig. 1.
Fig. 3 is front view of the present utility model.
In figure: 1, rivet nut 2, sleeve 3, flexible rod 4, sealing cover 5, position limit cycle 6, limited ring 7, draw ring.
Embodiment
Referring to accompanying drawing 1-3, the structure of the utility model embodiment comprises rivet nut 1, the end of described rivet nut 1 is provided with booster, this booster comprises the sleeve 2 being fixedly installed on rivet nut 1 end and the flexible rod 3 be set in sleeve 2, and the medial axis of described sleeve 2 is mutually vertical with the medial axis of described rivet nut 1.
The transverse section of described sleeve 2 is the outer square structure of inner circle.
Described sleeve 2 inwall be provided with position limit cycle 5, the outer wall of described flexible rod 3 is provided with limited ring 6, and flexible rod 3 end is provided with draw ring 7.
The length of described sleeve 2 equals the diameter of described rivet nut 1, and the length of described flexible rod 3 is less than the length of described sleeve 2.Also comprise the sealing cover 4 with the port match of described sleeve 2 in its structure, sealing cover 4 is fastened and connected with described sleeve 2 or is threaded.Sealing cover 4 can be covered in the port of sleeve 2 after flexible rod 3 indentation sleeve 2, play water proof anti-soil effect.
Working principle of the present utility model is: when needing dismounting or mounting screw, removed by sealing cover 4, pulled out by flexible rod 3 by draw ring 7 from sleeve 2, then pull flexible rod 3 i.e. rotatable rivet nut 1, completes dismounting or installment work.
When flexible rod 3 stretches out sleeve 2, add the moment of torsion be applied in rivet nut 1, dismounting or installment work are more prone to, booster and rivet nut 1 combine together, can complete disassemble and assemble work without the need to adopting other assistant tools.
By covering sealing cover 4 in flexible rod 3 indentation sleeve 2 after completing disassemble and assemble work, making booster volume-diminished, avoiding mutually disturbing with other workpiece of surrounding, sealing cover 4 can water proof anti-soil, avoids the normal operation affecting booster.
Foregoing description only proposes, not as the single restrictive condition to its technological scheme itself as the enforceable technological scheme of the utility model.
