Description
Technical field
The present invention relates to the connectors that can produce vibration between box spanner, especially box spanner and sleeve.
Background technique
The dismounting of nut at present is all mainly by spanner, including various box spanners, slow-witted mouth spanner, monkey wrench, plum blossom
Spanner etc..For the nut dismounting got rusty, six face of nut is likely to result in when disassembly using these common spanners
The case where skidding and can not tearing nut open generally requires smoothly dismantle by lubricating oil.If can provide one kind can generate
The spanner of vibration then can also smoothly dismantle rusted-on nut.
Currently, having some about shock driver design studies appearance.A kind of shock driver as disclosed in Chinese invention patent
(CN201510659514.2), eccentric shaft vibration is driven using motor and generates exciting force；For another example Chinese invention authorization discloses
Shock driver (CN201010172715.7), with motor drive swingle tap cavity inner wall and generate vibration.This two kinds of sides
Method can effectively generate exciting force, but require motor drive, so needing to be equipped with battery, and the direction of vibration generated is not
All along the tangential of six side of nut, so that the vibration in certain directions flogs a dead horse, this cannot play maximum vibration to nut dismounting
It is dynamic to unscrew effect.And both of which is designed to independent spanner, poor universality and cost is very high.
Summary of the invention
The present invention is intended to provide a kind of general connector of oscillatory type for box spanner, the universal joint can not change
Under the premise of the shape of existing box spanner, the oscillatory type dismounting of plurality of specifications rusted-on nut or normally tearing open for normal nut are realized
Dress, and structurally simple, economical property is good.
In order to solve the problems in the existing technology, present invention employs following technical solutions:
A kind of general connector of oscillatory type for box spanner, including,
One end of upper rotating cylinder, the upper rotating cylinder is provided with the connecting hole connecting with box spanner handle；
Lower rotating cylinder, one end of the lower rotating cylinder is provided with the connector connecting with collet head, and lower rotating cylinder and upper rotating cylinder are same
Axis；
First pawl and the second pawl, first pawl is rigidly fixed with upper rotating cylinder to be connect, second pawl with it is upper
The connection of rotating cylinder Elastic Sliding, Elastic Sliding here, which refers to, generates displacement by flexible deformation, and is realized in the form of sliding；
First ratchet and the second ratchet, first ratchet and the second ratchet are fixedly connected with lower rotating cylinder respectively, the first spine
Tooth is coplanar with the first pawl and matches, and the second ratchet is coplanar with the second pawl and matches, and the tooth of the first ratchet and the second ratchet
To on the contrary, teeth directional here refers to that the first pawl is in the first ratchet when the first pawl and the second pawl rotate in same direction on the contrary
The flank of tooth relative to sliding and the second pawl drives the second ratchet rotation (the two is opposing stationary).
Further, hollow guide cylinder is evenly equipped in the peripheral surface of the upper rotating cylinder.
Further, first pawl and the second pawl are respectively distributed in two planes perpendicular to upper tube rotaring axis.
Further, first pawl is evenly arranged on the lower circumferential of rotating cylinder.
Further, second pawl includes guide head, guide rod, striking head and spring；
The guide head is the rod-like structure part with hollow cavity, along through upper rotating cylinder peripheral surface direction and upper rotating cylinder
It is slidably connected；
One end of the guide rod is slidably connected in the hollow cavity of guide head, and the other end is connected with striking head, and is led
To on the outside of bar, be spring between striking head and guide head.
Further, first ratchet and the second ratchet are respectively distributed in two planes perpendicular to lower tube rotaring axis.
Further, first ratchet is multiple ratchets for being evenly arranged on lower rotating cylinder peripheral surface annular groove bottom.
Further, second ratchet is evenly arranged on disk peripheral surface, and the end face of disk is fixedly connected with lower rotating cylinder upper end.
It further, further include the variable adjustment collar of perimeter, the tune for the general connector of the oscillatory type of box spanner
Section lantern ring and the second pawl are coplanar and compress or loosen the second spine by the change of perimeter positioned at the outer circumferential direction of the second pawl
Pawl.
Further, the connecting hole is square hole, and the connector is square toes.
It should be noted that the pawl and ratchet of present invention meaning are the conventional structure of this field, i.e. pawl can drive spine
Pawl (ratchet) one-way movement, when reversed, pawl is slided in the flank of tooth of ratchet.
Core of the invention is being used cooperatively for two groups of ratchet and pawl arrangements, especially the first ratchet and the second ratchet
Teeth directional is opposite.Wherein, the first pawl with upper rotating cylinder due to being rigidly connected, so the first pawl can pass through when its one-directional rotation
First ratchet drives lower rotating cylinder to rotate together, to realize the effect for tightening nut, at this time the second pawl due to upper rotating cylinder bullet
Property be slidably connected, and the teeth directional of the second ratchet and the first ratchet on the contrary, so the second pawl the second ratchet the flank of tooth slide, not
Impact vibration is generated in glide direction.When the reversion of the first pawl, the opposite sliding on the flank of tooth of the first ratchet of the first pawl, on
Rotating cylinder can not drive lower rotating cylinder to rotate, and the second pawl drives the rotation of the second ratchet at this time, if nut rust is dead, what resistance generated
Torque is greater than the driving force of the second pawl, the second pawl can not the second ratchet of normal driving, but due to the rotation by force of upper rotating cylinder,
Cause the second pawl that elastic displacement occurs and slide, skips the second matched ratchet, then elastic displacement is resetted and slided
To another ratchet, and the ratchet is impacted, to realize tangential vibratory impulse torque, is produced by the jointing on lower rotating cylinder
Raw tangential force, plays the effect of loose nut, and after bump loose nut, the torque that nut resistance generates is less than the second spine
The driving moment that pawl generates, at this point, the second pawl drives lower rotating cylinder rotation by the second ratchet of driving, so that nut be unclamped.
The tooth form of ratchet with triangle be it is preferred, especially when two flank of tooth length of same ratchet difference is bigger, from
When the short side flank of tooth of one ratchet jumps to the short side flank of tooth of another ratchet, since the elastic displacement of the first pawl is bigger, meeting
Generate bigger impact vibration.
Compared with prior art, the present invention has following characteristics:
1, the present invention generates the percussion power of vibration using elastic displacement (such as spring force), and the percussion power vibrated is big
Small changed by the perimeter size of adjustment collar to realize adjustment；
2, of the invention for universal joint, under the premise of the shape that existing box spanner can not be changed, realize that plurality of specifications is raw
The oscillatory type dismounting of rust nut or the normal dismounting of normal nut, and structurally simple, economical property is good.
3, the present invention can both realize vibration disassembly nut, can also normally realize the rundown process of nut.
