Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise Embodiment, broadly falls into the scope of protection of the invention.
Below in conjunction with embodiment and detailed description of the invention, the present invention is further detailed explanation.
Self-locking nut structure, including the bolt 30 through first, second connecting plate 10,20, described bolt 30 stretches out second Be respectively arranged with first, second locking nut 40,50 on the shaft of connecting plate 10, described first, second locking nut 40,50 it Between be provided with locking sleeve 60, described locking sleeve 60 is in frustum tubular structure.
When practical set, by bolt 30 through the through hole of setting on first, second connecting plate 10,20, stretch at bolt 30 Go out and on the shaft of the second connecting plate 20, screw the first locking nut 40, after screwing, sheathed locking sleeve 60 on bolt 30, so After screw the second lock nut 50, until the second lock nut 50 and locking sleeve 60 against so that locking sleeve 60 becomes Shape, and sting tightly with by bolt 30, and then realize the locking to bolt 30, it is to avoid loosening of locking nut, thus improve plate The strong degree connected.
As the preferred version of the present invention, the end face of described first locking nut 40 is provided with groove 41, and described second Locking nut 50 is provided with protuberance 51 and is plugged in groove 41, and described locking sleeve 60 is positioned at groove 41 and arranges.Right for realizing The location of locking sleeve 60, utilizes the protuberance 51 of the second locking nut 50 to coordinate with the groove 41 of the first locking nut 40, and will Locking sleeve 60 holding is in groove 41, thus realizes the location to locking sleeve 60, by screwing the second locking nut 50, enters And make locking sleeve 60 be positioned at groove 41 and produce elastic deformation, and then the shaft of bolt 30 is stung tightly, and then realize spiral shell The locking of bolt 30.
For strengthening locking sleeve 60 elastic deformation ability, the little chi end face of described locking sleeve 60 supports with the bottom land of groove 41 Lean on, be provided with elastic washer 70 between little chi end face outer ring surface and the cell wall of groove 41 of locking sleeve 60, utilize elastic washer 70 can the effect of clamping screw 30 further, the elastic deformation of elastic washer 70 so that locking sleeve 60 extruding is tighter, And then further enhance locking effect.
For making first, second locking nut 40,50 screwing to during with the second connecting plate 20 plate face laminating, and make First, second locking nut 40,50 can synchronous axial system, be respectively arranged with between described first, second locking nut 40,50 One cascaded surface 42 and second-order tread 52 constitute ladder locking and coordinate.
It is provided with spring pad 80, described spring pad 80 between described first locking nut 40 and the plate face of the second connecting plate 20 It is set on bolt 30, utilizes spring pad 80 to can further improve locking effect.
Described first cascaded surface 42 include the first terrace and the first tread, described second-order tread 52 include the second terrace and Second tread, described first terrace and the triangle structure of the first tread, described second terrace and the second tread constitute triangle Shape structure.
Above-described is only the preferred embodiment of the present invention, it is noted that for those of ordinary skill in the art For, without departing from the concept of the premise of the invention, it is also possible to make some deformation and improvement, these broadly fall into the present invention Protection domain.
