Description
Technical field
The utility model is related to a kind of attachment means more particularly to a kind of clamping self-locking nuts.
Background technology
Nut is a kind of common fastener, and a set of clamp device is usually formed with screw combinations.In order to effectively reach more
It for effective fastening effect, prevents single nut from the phenomenon that voluntarily loosening occur, two nuts is used mutually simultaneously in many places
It is combined use, in the hope of further increasing fastening effect.
It is well known that two pieces type metal locking nut is by being placed in one, a metal nuts of rotatable fastening and one
Becket forms.Metal nuts are coaxial with becket, and helix alignment engages with bolt.This locking nut is by becket
It deforms to generate the power being applied on bolt, tightening retaining nuts and bolt.Becket bears higher in fastening and deformation
Stress can reach stronger fixed effect.But, this high stress can influence other characteristics of locking nut, for example, high stress
Be intended to limit the locking nut property reused after use and can upper sigma compactness again because after becket is detached from bolt
It will not restore its original size.Due to influencing steel characteristics, when locking nut is in high vibration or relatively rugged environment（Such as it adopts
The operations such as mine, crushing, crushing）Down in use, high stress also tends to shorten the service life of locking nut, therefore there is an urgent need for a kind of locks
Tight effect is good, is not easy the locking nut loosened.
Utility model content
To solve the above-mentioned problems, the purpose of this utility model is to propose a kind of clamping self-locking nut, by the way that taper is arranged
The structures such as locking slot, cone locking column and locking straight slot so that for nut in locking, locking effect is good, is not easy to loosen, and safety is steady
Gu it is easy for assemble or unload, the service life of nut is increased, entreprise cost is saved.
The technical solution that the utility model is taken to solve the above-mentioned problems is：A kind of clamping self-locking nut, including lock
Tight nut and setting thereunder by split nut, be set as two parts up and down inside lock nut, upper element center setting is recessed
Internal thread is arranged in groove, cone locking slot is arranged below groove, is set as hollow by split nut, in internal setting for slot
Screw thread is also configured as two parts up and down by split nut, and top, which is set up separately, sets cone locking column, and fixed block, cone locking is arranged in lower section
The locking straight slot of multiple staggeredly lockings is set on column, the centrum angle of cone locking slot is more than the centrum angle of cone locking column,
And the internal diameter of cone locking slot is less than the outer diameter of cone locking column, lead screw is passed through and is pushed by lock nut after split nut, by taper
Locking post is depressed into cone locking slot, turns lead screw to compress locking straight slot locking screw；
The locking straight slot is set as vertical, and decile is set as multiple；
The locking straight slot setting arc, and arc is obliquely installed in one direction, inclined angle is 30-45 °,
Several buckles and card slot to match are also set up between locking straight slot, cone locking slot squeezes taper locking post so that buckle and card
Slot clamping locks lead screw；
Cone locking column is divided into multiple latch segments by the locking straight slot, and buckle and card slot are located at the same lock
On the latch segment of tight straight slot both sides, buckle one end is fixedly connected with the latch segment for locking straight slot side, and conic clamp is arranged in the other end
Block, taper fixture block is mutually clamped with the card slot for being arranged in the locking straight slot other side, with locking screw；
The cone locking groove top end setting is highly located in lock nut lower part 2/3；
The bottom end setting of the cone locking column is highly located by split nut top 1/3.
The beneficial effects of the utility model：
1, the utility model is by being arranged cone locking slot and cone locking column, and multiple interlock is arranged on cone locking column
The locking straight slot of locking, the centrum angle of cone locking slot is more than the centrum angle of cone locking column, and cone locking slot is interior
Diameter is less than the outer diameter of cone locking column so that lock nut when in use, can be by cone locking slot to cone locking column
Pressure generates the pressure inwardly tightened so that lead screw securely locks in nut, reaches by locking post to central compression
Anti-loose purpose, it is good to achieve locking effect, is not easy to loosen, and safety and firmness is easy for assemble or unload, and increase nut uses the longevity
Life, saves the advantageous effect of entreprise cost；
2, the utility model is set as vertical by that will lock straight slot, and decile is set as multiple, facilitates and is locked,
Simultaneously to locking device there are certain surplus, locking while can also be protected to be deformed small by split nut, does not influence secondary use,
Increase the service life of lock nut；
3, arc is arranged by that will lock straight slot in the utility model, and arc is obliquely installed in one direction, inclined
Angle is 30-45 °, and several buckles and card slot to match are also set up between locking straight slot, and cone locking slot squeezes cone locking
Column so that buckle and card slot clamping lock lead screw, inwardly receive and staggeredly fasten annular locking, locking by one annular coupling mechanism force of formation
Effect is more preferable, and cone locking column is divided into multiple latch segments by the locking straight slot, and buckle and card slot are located at same
In the locking post of a locking straight slot both sides, buckle one end is fixedly connected with the locking post for locking straight slot side, other end setting cone
Shape fixture block, taper fixture block are mutually clamped with the card slot for being arranged in the locking straight slot other side, were both locked using cone locking column, card
Button and card slot combination can also carry out secondary locking, and locking effect is good, simultaneously because the presence of buckle and card slot, also mitigates locking
The deformation extent of block, reduces deformation extent, increases the service life of nut.
