Raw interference, anti-sliding stop annulus are skidded off out of moving hole.
In use, when safety cap is when unused, the first cap shell spherical outside surface part of safety cap is placed downwards,
So that the gravity that driving mechanism is subject to is directed to the first cap shell spherical outside surface；Between the second cap shell and third cap shell at this time
Gap will be less than 30mm, thus achieve the purpose that convenient for storage safety cap；When safety cap in use, use first
In person's wearing the present invention in safety cap when, with hand-drive handle motion, safety cap at this time has been worn on the head of user
On, handle, fixed block, movable block etc. will will receive under the gravity far from the first cap shell spherical, it will to far from first
The direction of cap shell moves, and gear ring at this time will will receive the rubbing action of third cap shell periphery, it will rotary motion, movement
Gear ring will drive first gear to move, and first gear will will drive the movement of the first fixing axle, and the first fixing axle will transfer the
Two gear movements, second gear will will drive third gear movement, since third gear movement form at this time is slowly to move,
So centrifugal-block at this time will not be moved along sliding groove, the third gear of movement will will drive rack movement, rack gear at this time
The movement of the second cap shell will be will drive, be equal to the diameter of third gear in the diameter of first gear；The diameter of second gear is equal to the
Under the action of 4 times of one gear diameter, so that the gap between the second cap shell and third cap shell is greater than 40mm, reach safety
The purpose of cap normal use, will make under the booster action of gravity and people hand driving mechanism will not third spring again work
Original position is restored under；When impact force of the safety cap at this time by weight, the first cap shell at this time will pass through
Impact force at this time is transmitted in the second cap shell by fixed column and sliding annulus, and the second cap shell will be transmitted to third tooth by rack gear
Wheel, this third gear will will drive centrifugal-block movement, and centrifugal-block will be subject to centrifugal forces, and centrifugal-block at this time will
It is moved along sliding groove, centrifugal-block at this time is by under the restriction effect of limited post, and third gear at this time will not rotate, at this time
Weight impact force will by the second fixing axle, third fixed plate, the second fixed plate, the first fixed plate, movable block effect,
It will be absorbed by second spring, and to achieve the purpose that protect user, the work of fixed column will be installed in the first cap shell Internal Spherical Surface
Annulus is slided with installation is easy for；The effect that sliding annulus is equipped on fixed column end face is support fixed column；First cap shell is logical
It crosses sliding annulus and sliding cavity is fitted in the second cap shell, and the work of the first cap shell Internal Spherical Surface and N number of rolling pearl cooperation
With being when weight is pounded to safety cap, weight at this time will give one impact force action of the first cap shell, in the work of this impact force
It will make to slide annulus under and relative motion occurs for sliding cavity, the head of people will be relatively original under the action of moving herein
Position shifts, to achieve the purpose that hide weight, reduces the purpose that weight injures user.
