Description
Technical field
The utility model relates to a kind of three ball fixator components of non magnetic unlocking.
Background technique
Three ball fixator of non magnetic unlocking typically now is all that steel bowl is motionless, so unlocking needle is taken less than, only three
Steel column and steel ball are generated by strong magnetic force to be displaced, and steel ball and steel bowl gap increase (because steel bowl is that the big lower section in space above is small), steel
Nail puller goes out to unlock, and existing three ball fixators in the family use, are equipped with strong magnetic unlocking tool there are certain security risk, and cost
It is high.Such as family's quilt core and quilt cover fixator, it is equipped with strong magnetic for unlocking, child is played mobile phone or wrist-watch with strong magnetic
When, it generates mobile phone or wrist-watch is scrapped.
Summary of the invention
In order to overcome three ball fixators of non magnetic unlocking to have the defects that security risk difference and at high cost, the utility model is mentioned
A kind of good safety, convenient for unlocking, three ball fixator component of non magnetic unlocking at low cost are supplied.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of three ball fixator components of non magnetic unlocking, including three ball fixators, three ball fixator include upper casing, under
The steel ball end of shell, steel bowl and three-hole steel column, the three-hole steel column is located in the steel bowl, and the component further includes unlocking part, institute
Stating unlocking part includes fixing seat and the unlocking needle being mounted in fixing seat, the unlocking needle setting at least two；
The middle part of the lower casing is equipped with groove, and boss is equipped in the groove, and the boss is equipped with and the needle on lower casing
The coaxial through-hole in hole, the steel bowl are sleeved on outside the boss by the way that bottom outlet thereon is moving up and down, the boss it is upper
End contacts with the three-hole steel column and acts against three-hole steel column fixed on upper casing, is additionally provided between the steel bowl and groove
Spring, the spring pocket is outside the boss, and the upper end of the spring is contacted with the bottom of the steel bowl, under the spring
End is fixed in the groove, and steel nail sequentially passes through fixing piece to be fixed, the pin hole on lower casing, leading on boss from bottom to top
Hole penetrates into three-hole steel column and is clamped by steel ball；
The upper casing is equipped with to be rectified with the same number of open keyhole of unlocking needle, the open keyhole and the upper of the steel bowl
It is right；
When steel nail needs to unlock, open keyhole on unlocking needle on unlocking part insertion upper casing and withstand on steel bowl upper end,
It pushes, steel bowl moves down, while compressed spring.
Further, there are three the unlocking needle settings, there are three the open keyhole settings, and one open keyhole corresponding one is opened
Purl, the bottom of the fixing seat are the arch to match with upper casing middle part.
The beneficial effects of the utility model are mainly manifested in: being unlocked without strong magnetic, safety is good；Unlocking needle only need to be pushed,
Convenient for unlocking；It is not required to be equipped with strong magnetic, and the simple position of fixator internal structure, it is at low cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of three ball fixators.
Fig. 2 is the structural schematic diagram of unlocking part.
Fig. 3 is the cooperation schematic diagram of unlocking part and three ball fixators when unlocking.
Fig. 4 is the top view of Fig. 1.
Fig. 5 is the bottom view of Fig. 2.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.
Referring to Fig.1~Fig. 5, a kind of three ball fixator components of non magnetic unlocking, including three ball fixators, three ball are fixed
Device includes upper casing 1, lower casing 2, steel bowl 3 and three-hole steel column 4, and 41 end of steel ball of the three-hole steel column 4 is located in the steel bowl 3, institute
Stating component further includes unlocking part, and the unlocking part includes fixing seat and the unlocking needle 10 being mounted in fixing seat, the unlocking
The setting of needle 10 at least two；
The middle part of the lower casing 2 is equipped with groove, and boss 21 is equipped in the groove, and the boss 21 is equipped with and lower casing 2
On the coaxial through-hole of pin hole, the steel bowl 3 is sleeved on outside the boss 21 by the way that bottom outlet thereon is moving up and down, described
The upper end of boss 21 contacts with the three-hole steel column 4 and three-hole steel column 4 is acted against to fixed on upper casing 1, the steel bowl 3
Spring 6 is additionally provided between groove, the spring 6 is sleeved on outside the boss 21, the upper end of the spring 6 and the steel bowl 3
Bottom contact, the lower end of the spring 6 is fixed in the groove, and steel nail 7 sequentially passes through fixation to be fixed from bottom to top
Part 8, the pin hole on lower casing 2, the through-hole on boss 21 are penetrated into three-hole steel column 4 and are clamped by steel ball 41；
The upper casing 1 is equipped with and the same number of open keyhole 11 of unlocking needle 10, the open keyhole 11 and the steel bowl 3
Upper end face；
When steel nail 7 needs to unlock, open keyhole 11 that unlocking needle 10 on unlocking part is inserted on upper casing 1 and steel bowl 3 is withstood on
