Description
Technical field
The utility model relates to optometric technology field, is specially a kind of earpiece.
Background technology
Spectacle frame is the important component part of glasses, mainly plays the effect of crutch glasses sheet, and rakish spectacle frame also can play effect attractive in appearance, and earpiece is an important component part in spectacle frame.
At present, the fuse in earpiece and slingshot shell are in engagement process, and fuse easily comes off from slingshot shell, cause earpiece easily to damage, meanwhile, slingshot shell is in the process of upset, the phenomenon that fuse easily swings, makes chip occur bending phenomenon, causes earpiece easily to damage.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of fuse and slingshot shell effective location, the earpiece that fuse not easily swings.
For achieving the above object, the utility model provides following technical scheme: a kind of earpiece, comprise slingshot shell and fuse, it is characterized in that: described slingshot shell offers blind hole, described slingshot shell also offers the stopper slot of positioning core, stopper slot is positioned at the aperture place of blind hole, in described slingshot shell, the hole wall of blind hole offers the skewed slot of ring-type, cutting ferrule is provided with in skewed slot, blind hole is stretched in one end of described fuse, and be connected with conflicting at the bottom of the hole of blind hole, the other end of fuse and stopper slot are fitted, fuse comprises chip and spring, described spring housing is located on chip, chip is provided with the first reference column and the second reference column that limit spring position, described chip is provided with the 3rd reference column of positioning sleeve.
Further, described cutting ferrule is set in outside fuse, and cutting ferrule is provided with the centring ring for fixing fuse.
Further, described 3rd reference column is adjacent with the first reference column, and the external diameter of first grade of post is less than the external diameter of the 3rd reference column.
Further, described slingshot shell is also provided with two nail pin.
Contrast the deficiencies in the prior art, the beneficial effect that the technical scheme that the utility model provides is brought: 1. the utility model is by skewed slot positioning sleeve, the centring ring that cutting ferrule is provided with, centring ring is engaged with the second reference column, fuse is limited by spring and the 3rd reference column, make fuse be not easy to depart from slingshot shell, and then make earpiece be not easy to damage, extend the service time of earpiece.2. the stopper slot that is provided with by slingshot shell of the utility model, fuse is made to stretch into blind hole, and fit with stopper slot, effective positioning core, make fuse not produce rotation, also increase the cooperation position of fuse and slingshot shell, decrease the degree that fuse swings, effectively prevent fuse severe bends and the phenomenon that causes earpiece to damage occurs, and then extend the service time of earpiece.3. the utility model is also provided with the design of two nail pin by slingshot shell, when earpiece to coordinate with pile crown in the process overturn, follows closely pin and can effectively prevent from overturning the phenomenon making the syndeton of chip and spring damage when overexerting and occur.

Embodiment
With reference to Fig. 1-Fig. 5, the utility model is described further.
A kind of earpiece, comprise slingshot shell 1 and fuse 2, it is characterized in that: described slingshot shell 1 offers blind hole 11, described slingshot shell 1 also offers the stopper slot 12 of positioning core 2, stopper slot 12 is positioned at the aperture place of blind hole 11, in described slingshot shell 1, the hole wall of blind hole 11 offers the skewed slot 13 of ring-type, cutting ferrule 3 is provided with in skewed slot 13, blind hole 11 is stretched in one end of described fuse 2, and be connected with conflicting at the bottom of the hole of blind hole 11, the other end and the stopper slot 12 of fuse 2 are fitted, fuse 2 comprises chip 21 and spring 22, described spring 22 is set on chip 21, chip 21 is provided with the first reference column 23 and the second reference column 24 limiting spring 22 position, described chip 21 is provided with the 3rd reference column 25 of positioning sleeve 3.
The stopper slot 12 be provided with by slingshot shell 1, fuse 2 is made to stretch into blind hole 11, and fit with stopper slot 12, effective positioning core 2, make fuse 2 not produce rotation, also increase fuse 2 and the cooperation position of slingshot shell 1, decrease the degree that fuse 2 swings, effectively prevent fuse 2 severe bends and the phenomenon that causes earpiece to damage occurs, and then extend the service time of earpiece.
Further, described cutting ferrule 3 is set in outside fuse 2, and cutting ferrule 3 is provided with the centring ring 31 for fixing fuse 2.
Centring ring 31 is adaptive with the first reference column 23 and be engaged, and plays the effect of effective fixing fuse 2.
Further, described first reference column 23 is adjacent with the 3rd reference column 25, and the external diameter of the first reference column 23 is less than the external diameter of the 3rd reference column 25.
The external diameter of the 3rd reference column 25 is larger than the external diameter of the first reference column 23, at cooperation spring 22, makes cutting ferrule 3 effectively fixing fuse 2.
By skewed slot 13 positioning sleeve 3, the centring ring 31 that cutting ferrule 3 is provided with, centring ring 31 is engaged with the second reference column 24, fuse 2 is limited by spring 22 and the 3rd reference column 25, make fuse 2 be not easy to depart from slingshot shell 1, and then make earpiece be not easy to damage, extend the service time of earpiece.
Further, described slingshot shell 1 is also provided with two nail pin 14.
The design of two nail pin 14 is also provided with by slingshot shell 1, when earpiece to coordinate in the process overturn with pile crown, nail pin 14 can effectively prevent from overturning phenomenon when overexerting, chip 21 and the syndeton of spring 22 being damaged and occur, and meanwhile, can directly coordinate plastics temple.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, those skilled in the art carries out common change and replaces should being included in protection domain of the present utility model within the scope of technical solutions of the utility model.
