Abstract
The invention discloses a locking nut, and belongs to the field of hardware fittings. The locking nut consists of a fixed nut and a movable nut. The fixed nut is provided with a locking sleeve, a pressure bearing projection, a jaw port, a jaw, a jaw recess, an anti-releasing projection, a deformation port and a positioning recess; and the movable nut is provided with an assembly tank, an anti-releasing tank, a pressure applying ring and a positioning projection. Firstly, the fixed nut is screwed in a matched bolt until the screwing is tight; one surface, having the positioning projection, of the movable nut is towards the fixed nut; the movable nut is inserted in the locking sleeve, and rotates to clamp the anti-releasing projection into the anti-releasing tank; the pressure applying ring presses the pressure bearing projection; the jaw is matched with the screw rod; and the positioning projection slides into the positioning recess, so that the locking nut is locked on the screw rod. The disassembly process and the locking process are opposite.
Description
Technical field:
The present invention relates to a kind of locking nut, belong to five metals Component field.
Background technique:
Current existing nut is of a great variety, all has his own strong points, and application area also widely.They or increase only hook bolt, or increasing " fixture block " makes structure and complicated operation and is unfavorable for miniaturization; Or centrum fluting, or eccentric structure, being all by increasing pressure, the friction between metal is increased mostly, reaching fixing object; But all cannot by nut locking on bolt.
Summary of the invention:
The technical issues that need to address of the present invention are, overcome the deficiency of background technique, provide a kind of nut that self can be locked on bolt, are specially adapted in the structure of long-time high strength vibrations.Content of the present invention is as follows.
1, structure:
Locking nut is by determining nut and dynamic nut forms.It determines nut has locking overlap, and pressure-bearing is dashed forward, contract pawl mouth, contract pawl, and contract pawl is recessed, and anticreep is dashed forward, and is out of shape mouth and locates recessed; Its dynamic nut having fitting recess, anticreep groove, dashes forward in pressing ring and location.
2, working principle:
First the bolt that matches is screwed in until screw by determining nut.
Allow nut have location prominent one facing to determining nut, makes fitting recess and anticreep position of dashing forward corresponding, dynamic nut is inserted in locking and overlaps.
Revolve rotating nut, anticreep is dashed forward and snaps in the anti-stop nut shaft of anticreep groove to deviating from; Simultaneously pressing ring slides to pressure-bearing and dash forward and to oppress pressure-bearing prominent.Due to locking cover and pressing ring is isometrical can relative sliding, and pressure-bearing external diameter of dashing forward is greater than pressing ring, and therefore pressure-bearing is dashed forward and is pressed ring and presses to axle center; Owing to having contract pawl mouth and distortion mouth, pressure-bearing teat position just can be made more easily to be out of shape to axle center skew, while contract pawl also just agree with screw rod, reach determine nut can not the object of counterrotating.The object of the recessed appearance of contract pawl is to not hinder agreeing with of contract pawl and screw rod, making to agree with better effects if.
It is recessed that the meanwhile prominent rotation along with dynamic nut in location slips into location, relative with the position of dynamic nut fixing by determining nut, make it can not allow under external impacts or sharp pounding and determine nut and dynamic nut and produce relative movement, also would not cause locking nut loosen thus by nut locking on screw rod.
When disassembly is desired, will move nut counterrotating, location is prominent, and to skid off location recessed, pressing ring leaves pressure-bearing and dashes forward, and pressure-bearing teat position is by recoverable force original state, and contract pawl leaves screw rod, fitting recess is prominent with anticreep again correspondingly just desirablely sets out nut, then back-out is determined nut and just completed dismounting.
Accompanying drawing illustrates:
Fig. 1 is schematic appearance, and Fig. 2 determines nut schematic diagram, and Fig. 3 is nut leading flank schematic diagram, Fig. 4 is nut trailing flank schematic diagram.
Embodiment:
Below in conjunction with accompanying drawing, the invention will be further described.
1, structure:
Locking nut is by determining nut (1) and dynamic nut (2) forms.It determines nut (1) there is locking cover (3), and pressure-bearing is dashed forward (4), contract pawl mouth (5), contract pawl (6), contract pawl recessed (7), anticreep is dashed forward (8), distortion mouth (9) and location recessed (10); Its dynamic nut (2) there is fitting recess (11), anticreep groove (12), pressing ring (13) and location prominent (14).
2, working principle:
First the bolt that matches is screwed in until screw by determining nut (1).
Nut (2) is allowed to have one of location prominent (14) facing to determining nut (1), make prominent (8) position of fitting recess (11) and anticreep corresponding, nut (2) will be moved and be inserted in locking cover (3).
Revolve rotating nut (2), make anticreep prominent (8) snap in anticreep groove (12) anti-retainer nut (2) and axially deviate from; Pressing ring (13) slides to pressure-bearing prominent (4) and oppresses pressure-bearing prominent (4) simultaneously.Due to locking cover (3) and pressing ring (13) is isometrical can relative sliding, and prominent (4) external diameter of pressure-bearing is greater than pressing ring (13), therefore pressure-bearing dash forward (4) be pressed ring (13) and press to axle center; Owing to having contract pawl mouth (5) and distortion mouth (9), prominent (4) position distortions of pressure-bearing just can be made to offset to axle center, simultaneously contract pawl (6) is also just agreed with screw rod, reach determine nut (1) can not the object of counterrotating.The object of contract pawl recessed (7) appearance is to not hinder agreeing with of contract pawl (6) and screw rod, making to agree with better effects if.
Meanwhile location prominent (14) slip into location recessed (10) along with the rotation of dynamic nut (2), nut (1) will be determined relative fixing with the position of dynamic nut (2), make it can not allow under external impacts or sharp pounding and determine nut (1) and dynamic nut (2) generation relative movement, the entirety of locking nut also would not be caused to loosen thus locking nut be locked on screw rod.
When disassembly is desired, nut (2) will be moved all can by former sense of rotation or counterrotating, location prominent (14) skids off location recessed (10), pressing ring (13) leaves pressure-bearing prominent (4), prominent (4) position of pressure-bearing is by recoverable force original state, contract pawl (6) leaves screw rod, prominent with anticreep (8) are corresponding again just desirablely sets out nut (2) for fitting recess (11), then back-out is determined nut (1) and completed dismounting.
