Abstract
The utility model proposes a kind of double nuts to tighten locked spanner, including worm gear, shell, head cover, worm screw, one-way clutch and handle, and main nut is tightened using the small tooth on shell, and the tooth in worm gear tightens locking nut, realizes while tightening two nuts；In vertical direction, it holds with a firm grip and handle and pushes, drive worm gear mechanism movement, realize that nut in shell is motionless and the nut in counter-tightened worm gear.When counter-tightened nut, nut can be tightened with one-handed performance, it is more convenient safer for the staff of working at height.
Description
Technical field
The utility model is related to mechanical wrench fields, and in particular to a kind of double nut tightens locked spanner.
Background technology
Spanner is a kind of common installation and extracting tool, be using lever principle twist bolt, screw, nut and other
Screw thread tightly holds the opening of bolt or nut or the hand tools of trepanning firmware.
It is either to utilize coarse thread nut and serrated nut to top using double nut to have some locking nuts on the market at present
The different principles of helical pitch realize tightening and locking for double nut.But this kind of nut needs Tongfang simultaneously when generally tightening
To two nuts are tightened, there is that some cases also need to while negative direction tightens two nuts, and common wrench on the market is current
This kind of nut while the requirement tightened are cannot be satisfied, being specifically exactly market does not have a kind of spanner that can while tighten double nut in the same direction
And can also simultaneously counter-tightened double nut.Therefore, the problem of being deposited for the prior art, it should which design is a kind of to be directed to this lock
The spanner of tight nut.
Utility model content
The technical problems to be solved in the utility model：It is to use double nut to pushing up either to have some locking nuts on the market
Tightening and locking for two nuts, this kind of nut one are realized using the coarse thread nut principle different from serrated nut helical pitch
As need when tightening it is equidirectional simultaneously tighten double nut, or negative direction tightens double nut simultaneously.
The technical solution of the utility model is as follows：A kind of double nut tightens locked spanner, including worm gear, shell, head cover, snail
Bar, one-way clutch and handle.
The worm gear center position is provided with hole, and the shape in hole is that two regular hexagons intersect the shape obtained after 30 degree with one heart
Shape.
The shell includes locking nut screwing structure and main nut screwing structure, and locking nut screwing structure is to be designed with
The semicircular ring of ears, for installing worm gear, there are two threaded holes for the top design at semicircular ring both ends, for installing head cover, ears
Middle position is also configured with threaded hole, is used for connecting worm, and main nut screwing structure is the hole that inner ring inner lane has 6 small teeth,
Small tooth is uniformly arranged, and for tightening main nut, while can smoothly extract spanner, locking nut screwing structure after ensureing nut check
Above main nut screwing structure, the two is stepped in position, ensures that worm gear will not be close to main nut screwing structure,
The two is set there are certain intervals.
The worm and wheel engagement, forms worm gear mechanism, for tightening locking nut, worm screw is hollow, both ends
It is separately installed with one-way clutch, worm screw fixing bolt screws in the threaded hole in one ear mount of shell, and passes through worm screw, from shell
Threaded hole in another ear mount screws out, then is fixed with worm screw fixing nut, and there are two annulus for the handle Front-end Design, unidirectionally from
Clutch outer ring is linked in two annulus of handle front end.
The head cover is used to compress worm gear inside the housing, threaded hole is designed on head cover, head cover and shell pass through spiral shell
Nail is fixed.
The utility model has the beneficial effects that：A kind of double nut of the utility model tightens locked spanner, using on shell
Small tooth tightens main nut, and the tooth in worm gear tightens locking nut, realizes while tightening two nuts；In vertical direction, it holds with a firm grip
Handle simultaneously pushes, and drives worm gear mechanism movement, realize in shell nut is motionless and counter-tightened worm gear in nut.Instead
To when tightening nut, nut can be tightened with one-handed performance, it is more convenient safer for the staff of working at height.

Specific implementation mode
For the ease of understanding the utility model, with reference to the accompanying drawings of the specification with specific implementation mode to the utility model into
Row more detailed description.
A kind of double nut of the utility model tightens locked spanner, including worm gear 4, shell 5, head cover 3, worm screw 1, one-way clutch
Device 2 and handle 6；The shell includes locking nut screwing structure 7 and main nut screwing structure 8,7, locking nut screwing structure
Above main nut screwing structure 8, locking nut screwing structure 7 is to design biaurite semicircular ring, and snail is equipped in semicircular ring
Wheel 4, main nut screwing structure 8 are the hole that inner ring inner lane has 6 small teeth, and small tooth is uniformly arranged.4 center position of the worm gear is opened
There is hole, the shape in hole is that two regular hexagons intersect the shape obtained after 30 degree with one heart, is pressed in shell 5 by head cover 3,
Worm gear 4 engages into worm gear mechanism with worm screw 1, and 1 both ends of worm screw are separately installed with one-way clutch 2,2 outer ring of one-way clutch
It is linked in two annulus of 6 front end of handle, worm screw fixing bolt is screwed in from the threaded hole in 5 one ear mounts 9 of shell, passes through snail
Bar 1, then screwed out from the threaded hole in 5 another ear mount 9 of shell, finally fixed with worm screw fixing nut.
In use, the required double nut tightened hand is screwed in corresponding bolt, it, will when screwing in soon arrival compressing member
Double nut rotation into alignment；In the same direction when tightening double nut, locked spanner shell 5 is tightened with a kind of double nut provided by the utility model
Hole in interior hole and worm gear 4 is aligned double nut, and fitting is together, and then rotational handle tightens double spiral shells in the horizontal direction
It is female；When counter-tightened double nut, need counter-tightened is the nut in worm gear 4, at this point, in vertical direction, holding with a firm grip simultaneously
Handle is pushed, worm gear mechanism movement is driven, it is locked to achieve the purpose that by the nut counter-tightened in worm gear 4.
A kind of double nut of the utility model tightens locked spanner, and one-way clutch 2 also can be used ratchet to replace, ratchet suit
In 1 both sides of worm screw, form ratchet mechanism, it is same can be achieved and meanwhile it is equidirectional tighten two nuts, or negative direction tightens two simultaneously
A nut.
