Description
Technical field
Torque nut component is determined the present invention relates to a kind of, determines torque suitable for install lavatory lid more particularly to a kind of
Nut assembly.
Background technique
Nut assembly is clamped on structural member (such as closestool) for being screwed in screw rod, cooperation screw rod.Nut in order to prevent
Component coupling mechanism force is excessive and destroys structural member, ratchet nut component occurs, the working principle of ratchet nut component is by inward turning
Turn part to be nested in outer revolving part, design click structure therebetween, outer revolving part drives interior rotation when rotating forward
Part rotates together, achievees the purpose that locking, and when torsion reaches setting value, and click can separate by force and make outer rotation
Part no longer drives inward turning to walk around rotation, when rotating backward outer revolving part drive in revolving part rotate together, reach release purpose.
Current this kind of ratchet nut component, the small precision of click structure size between inside and outside revolving part is high, moreover, outside
Need to be arranged grooving on revolving part to provide the possibility of click deformation, further, it is also necessary to jacketed on the outside of outer revolving part
Spring ring, therefore, structure are extremely complex, and die sinking difficulty is big.
Summary of the invention
The present invention provides a kind of structures simply to determine torque nut component.Used by the present invention solves its technical problem
Technical solution is:
It is a kind of to determine torque nut component, comprising: shell, the inner cavity of the shell extend upward its top surface, the housing bottom surface
Center is equipped with the relief hole being pierced by for screw rod；Adapter is limited, which is placed in the inner cavity vertically movablely
It rotates synchronously in the circumferential in the middle and with the shell, vertical perforative through-hole is equipped in the middle part of the limit adapter, which turns
Fitting top surface is equipped at least one pushing block on the periphery of the through-hole, and the two sides of the pushing block are respectively formed locking inclined-plane and unclamp side
Face；Spring, the spring are placed in the inner cavity and apply upward thrust to the limit adapter；Nut, the nut snap onto
To push down the limit adapter, which can circumferentially rotate the case top with respect to the shell, be equipped in the middle part of the nut vertical
Perforative screw hole, the periphery of the screw hole lower ending opening are equipped with convex block, the two sides of the convex block be respectively formed agree with inclined-plane and against
Side；This agrees with inclined-plane and corresponds to locking inclined-plane setting, rotates forward the shell and limit adapter, locking inclined-plane fitting should
Agree with inclined-plane to push the cap rotation the nut is screwed in screw rod, after screwing the nut, which compresses
The spring simultaneously gradually moves down the pushing block is enabled to cross the convex block；The abutment side surface corresponds to release side setting, reversed to turn
The shell and limit adapter are moved, which is bonded the abutment side surface to drive the nut to screw out screw rod.
Among one preferred embodiment: the cross section of the inner cavity be it is non-circular, the side profile of the limit adapter is corresponding should
The shape of inner cavity is arranged, which is clamped in the circumferential with the limit adapter.
Among one preferred embodiment: the cross section of the inner cavity is regular polygon.
Among one preferred embodiment: the pushing block is two and is symmetrical arranged with the central axes of the through-hole that the convex block is also
Two and with the central axes of the screw hole be symmetrical arranged.

Among one preferred embodiment: the surrounding of the nut is downwardly extending a circle baffle ring, the baffle ring inner surface it is following
Along hook is equipped with, which, which extends to the outside to be formed, thickens connector, which entangles this and thicken connector, which is buckled in
This thickens the bottom surface of connector.
Among one preferred embodiment: this thickens the outside at the top of connector and corresponds to the hook equipped with guide groove.
Among one preferred embodiment: the position of the nut and the hook vertical non-alignment is equipped with perforation.
Among one preferred embodiment: the release side and abutment side surface are perpendiculars.
The technical program compared with the background art, it has the following advantages:
1. the inclined-plane that agrees with for limiting the locking inclined-plane of the pushing block of adapter and the convex block of nut matches, rotates forward limit and turn
Fitting can push nut to rotate forward, so that nut is screwed in screw rod, when the torque of nut increases to predetermined value, limit turns
Fitting can not push nut again, and pushing block compressed spring under the guidance for agreeing with inclined-plane moves down, and convex block finally be crossed, in this way, can
To guarantee that the torque value that screws screws according to set requirements, will not revolve it is too small cause to shake, or the too tight of rotation destroys
Part.By locking inclined-plane and agree with inclined-plane cooperation and realize and screw promotion and resigning, limits the structure of adapter and nut very
Simply, it is easy production.
2. locking inclined-plane and agreeing with the tilt angle on inclined-plane and the elastic force of spring, determine that tightening nuts are maximum
Therefore torque value changes locking inclined-plane and agrees with the tilt angle on inclined-plane and/or the elastic force of spring, so that it may change nut
Degree is screwed, when can easily be adjusted according to actual needs in production.
3. the limit adapter is inserted directly into inner cavity and is clamped in the circumferential with shell, structure is simple.
4. the nut thickens connector with shell using the hook of baffle ring and is interlockingly connected, assembly dress is single.Thicken leading at the top of connector
Hook can be led to slot, facilitate hook and thicken connector combination.
