Description
Technical field
The utility model belongs to floor clip field, more particularly to a kind of spine dentition formula floor clip.
Background technology
It is a kind of common machinery company closely to be connected parts and components using bolt, nut and washer fastening structure part
Connect method.The torque and self-locking property that gasket construction form therein coordinates screw bolt and nut have very important influence.
The cooperation of bolts and nuts is set not loosened under normal use state, generally all need to first pack into plain cushion on bolt packs into bullet again
Property washer screw on nut again.Plain cushion therein easily rotates during screw on nut, and the rubbing action with connected piece makes work
Part surface sustains a damage, and prescribed requirement is not achieved with the torque for causing bolt to be born.
Utility model content
The purpose of this utility model is to provide a kind of spine dentition formula floor clip, to realize the process prevented in screw on nut
Middle washer rotates the damage to workpiece surface, and reduces influence of the washer to moment of torsion control.
The technical solution adopted is that：
A kind of spine dentition formula floor clip, including bottom ratchet wheel, upper ratchet, multiple ratchets, multiple springs, multiple closure screws and
Clamp spring, it is characterised in that：
Upper ratchet is loop configuration, and multiple triangles, key or polygon are equidistantly equipped on the annular outer wall of upper ratchet
The gear teeth are equidistantly equipped with multiple first ratchets on the right side of upper ratchet, and the left side of upper ratchet is shiny surface.In upper ratchet
Internal jump ring slot is offered on inner wall.
It is equidistantly equipped with multiple gear teeth on the arc outer wall of bottom ratchet wheel, multiple the are equidistantly equipped on the left side of bottom ratchet wheel
Two ratchets offer stairstepping through-hole on the right side of bottom ratchet wheel, and the raised head face of stairstepping through-hole is shiny surface.Stairstepping
The right end of through-hole is the first hole, and the left end of stairstepping through-hole is the second hole, and the diameter in the second hole is less than the diameter in the first hole.First
The thickness in hole is identical with the thickness of upper ratchet.On the inner wall in the first hole wild card is offered on the corresponding position of internal jump ring slot
Spring slot.It is equidistant on the inner wall in the first hole along the circumferential direction to offer multiple ratchets mounting hole positioned at the left side of outer jump-ring slot,
Pawl mounting hole is stairstepping through-hole, and the apertura lateralis of pawl mounting hole is the diameter that threaded hole and diameter are more than inboard aperture.
Upper ratchet is installed in the clearance fit that in the first hole and fit clearance is 0.1 ~ 0.2mm.Clamp spring is installed in internal jump ring
In slot and outer jump-ring slot.
Each pawl, spring and closure screw are installed in from the inside to the outside successively in corresponding pawl mounting hole, pawl and bullet
Spring play, closure screw and pawl mounting hole can be threadedly coupled in pawl mounting hole.Spring one end is supported on pawl, another
It supports on blocking screw at end.
It is equipped with boss in the tail portion of pawl.
The course of work：Bolt is first injected two when use to need in flange hole, then spine dentition formula floor clip is installed,
Tightening nut again goes up ratchet since the effect of ratchet makes it be relatively fixed motionless, lower spine with nut during tightening nut
Wheel also due to the effect of ratchet so that it is relatively fixed with connecting plate motionless, and upper ratchet shiny surface and lower ratchet shiny surface) between
Reduce frictional force due to smooth, relative rotational sliding reduces the heavy losses of torsion in nut rundown process.It screwed
Cheng Zhong, pawl prevent ratchet from inversely loosening.Simultaneously bottom ratchet wheel ratchet face and connecting plate during nut tightening without phase
To movement, achieve the purpose that not damage connection plate face.Pawl in spine dentition formula floor clip prevents connecting flange due to external force
Effect has the tendency that inversely loosening and mechanically preventing it.Spine dentition formula floor clip reduces biasing torque and applies to bolt simultaneously
The influence of torque.The utility model is easy to use, and applicable situation is extensive.
It the advantage is that：Spine dentition formula floor clip is that a kind of one direction screws, and prevents the mechanism inversely loosened.This practicality is new
Type is firmly linked the flange of docking by spine dentition formula floor clip and the Integral connection structure of bolt and nut and various flanges
It is integrated.During screwing, upper ratchet is motionless since the effect of ratchet makes it be relatively fixed with nut, bottom ratchet wheel also due to
It is motionless that the effect of ratchet makes it be relatively fixed with connecting plate, and between upper ratchet shiny surface and lower ratchet shiny surface due to smooth and
Reduce frictional force, relative rotational sliding, a large amount of losses of torque when to reduce rotating nuts.Reduce bias force simultaneously
Square applies bolt the influence of torque.The utility model is easy to use, and applicable situation is extensive.
