Description

A kind of gyro

Technical field

The utility model is a kind of gyro, specifically a kind of gyro with key chain function.

Background technology

Existing gyro only has spinfunction, and function is single and profile is traditional, can not constantly occupy market, is formed long-term Circulation industrial chain, industry occur this bottleneck can not be broken for a long time.In view of this, there is provided one kind can have key Key ring function, the product for having whipping top function again necessitate.

The content of the invention

In view of the shortcomings of the prior art, the utility model, which provides one kind, not only has spinfunction, but also there is key chain The gyro of function.

To reach above-mentioned purpose, technical scheme provided by the utility model is：A kind of gyro, including centrosymmetric base Part and pivot structure, the center of substrate offer through hole, and pivot structure is set in the through hole of substrate, and substrate can be tied around the shaft The central rotation of structure, the both ends of described substrate are equipped with clasp, the Central Symmetry of the clasp based on pivot structure at substrate both ends, Clasp includes the clasp matrix with opening and can open and close the block piece of opening.

By such scheme, because the both ends of substrate are provided with clasp, and clasp includes clasp matrix and block piece, makes gyro Key and other items can be dressed by clasp matrix or gyro is hung on belt, then is closed and is open by block piece, equivalent to top Spiral shell becomes key chain use, is convenient for carrying small article, while be also convenient for the carrying of gyro in itself.

Further, above-mentioned block piece is arcuate structure, and one end and the clasp matrix of block piece are hinged, block piece it is another One end can be with clasp matrix snapping.End and clasp matrix snapping by block piece, avoid block piece in closed state It is natural opening.

Further, above-mentioned block piece can be provided with neck, clasp matrix pair with the inner side of one end of clasp matrix snapping Answer the position of neck to be provided with projection, block piece in closed state, projection and the neck snapping of block piece of clasp matrix, so as to Fixation is played to block piece, avoids block piece from opening naturally.

Further, the position of above-mentioned clasp matrix respective protrusions offers fixing hole, and spring is provided with fixing hole, Gu The orifice position for determining hole is provided with floating block, and spring is between floating block and the bottom hole of fixing hole, and spring is in compressive state, floating block Part expose outside fixing hole, the part that floating block exposes outside fixing hole forms projection.By this structure, because above-mentioned projection is Expose fixing hole outer portion by floating block to be formed, and floating block can freely be stretched by spring in fixing hole so that the card of block piece Groove and the snapping of projection are more flexible.

Further, above-mentioned pivot structure includes conllinear female nail and the son nail in center, and mother's nail includes female ailhead and is located at Female head of a nail of female ailhead end, sub- nail include sub- ailhead and the sub- head of a nail located at sub- ailhead end, and sub- ailhead and female ailhead pass through The through hole of substrate is connected with each other, and female head of a nail and the sub- head of a nail respectively can be around the centers that female nail and son are followed closely positioned at the both sides of substrate, substrate Rotation.By this structure, pivot structure is interconnected to form by mother's nail and son nail, and female head of a nail and the sub- head of a nail are located at substrate respectively Both sides, in the case where not influenceing the normal rotation of gyro so that the structure of gyro is simpler, facilitates the dismounting of gyro.

Further, in order to reduce the friction of pivot structure and substrate, between above-mentioned pivot structure and the hole wall of through hole Bearing is additionally provided with, makes the rotation of substrate more smooth.

Further, the side wall after above-mentioned sub- ailhead is connected with female ailhead is provided with first annular groove, the inner ring of bearing with First annular groove coordinates so that bearing be connected with sub- ailhead and female ailhead after side wall cooperation it is closer, while to bearing Positioned, reduce adapted space and coordinate more firm.

Further, the hole wall of above-mentioned through hole offers the second annular groove, the outer ring of bearing and the second annular groove Coordinate so that the cooperation of the hole wall of bearing and through hole is closer, further reduces adapted space and coordinates more firm.

Further, the outer face of above-mentioned female head of a nail and the sub- head of a nail is inner concave arc surface, convenient to match with finger, is rotated Easily control.

Gyro of the present utility model not only has spinfunction, and has key chain function, and purposes is various, conveniently takes Band, it is simple in construction, it is easy to manufacture.
