Abstract
An anti-loose hydraulic pipe connector relates to the field of hydraulic pipes and comprises a connector body, a loose joint nut body, a connecting tube and a sealing ring. An outer hexagon which is coaxial with the connector body is arranged at the butt-joint thread bottom of the connector body, a flange edge which is larger than the outer hexagon in diameter is arranged on an end face of the outer hexagon which is correspondingly contacted with the loose joint nut body, a plurality of through holes are evenly arranged on the flange edge, and axis of the flange edge is parallel to that of the through holes. A butt-joint edge which is larger than the loose joint nut body in diameter is arranged on the end face of the loose joint nut body contacting with the outer hexagon, a plurality of butt-joint holes are evenly arranged on the butt-joint edge, and the axis of the butt-joint edge is parallel to that of the butt-joint holes. The pitch diameter of the butt-joint holes is equal to that of the through holes, and the butt-joint holes are at least one more than the through holes. The connector is simple in locking method and reliable in locking effect and has effective shake-resistant effect and anti-loose effect.
Description
[technical field]
The utility model relates to the hydraulic tube field, especially relates to a kind of locking hydraulic fitting that can prevent effectively that joint is loosening.
[background technique]
Known, in hydraulic plumbing system, often to use pipe joint with loose joint structure, but no matter be the pipe joint of end face seal; Like standard No. is the pipe joint of JB/T966-1977, or the pipe joint of conical surface seal, is the pipe joint of JB/T6383.1-2007 like standard No.; These joints do not possess special locking structure; Therefore, when these pipe joints be applied in some like the bigger equipment of vibration such as hot rolling mill on the time be stiff dough contact seal because it adopts; So it is under the situation that is in vibrational state for a long time; The influence that the surface of contact of pipe joint is very easily vibrated and becoming flexible promptly causes the pipe joint spiral marking connection loosening, thereby causes the pipe joint leakage of oil.
[model utility content]
In order to overcome the deficiency in the background technique, the utility model discloses a kind of locking hydraulic fitting, described joint not only locking mode is simple, and locking effect is reliable, and can also effectively play the shock-proof check effect.
To achieve these goals, the utility model adopts following technological scheme:
A kind of locking hydraulic fitting, described joint comprise joint body, loose joint nut body, adapter and seal ring; The butt joint thread bottom of said joint body is provided with outer six sides coaxial with joint body, and the corresponding end face that contacts with the loose joint nut body of six sides is provided with the flanged lip greater than outer six side's diameters outside; Described flanged lip evenly is provided with the through hole of a plurality of axle center and flanged lip axis parallel; Described loose joint nut body is provided with the butt joint rim greater than loose joint nut body diameter with the end face of the corresponding contact of outer six sides; Described butt joint rim evenly is provided with a plurality of axle center and the butt hole that docks the rim axis parallel; Described butt hole equates with the through hole standard pitch diameter, and the quantity of butt hole has more one at least than the quantity of through hole.
Described locking hydraulic fitting, described outer six side's diameters are greater than the joint body diameter.
Described locking hydraulic fitting, described flanged lip or butt joint rim are made as circle or polygonal.
Described locking hydraulic fitting, described flanged lip and butt joint rim equal diameters.
Owing to adopt aforesaid technological scheme, the utlity model has following beneficial effect:
Described locking hydraulic fitting only needs to insert corresponding tube head respectively in use the two ends of said joint; Tighten the loose joint nut body is corresponding with joint body again; Between through hole that aligns and butt hole, run through corresponding fasteners then, and loose joint nut body and joint body are tightened together through fastening piece; Described joint not only locking mode is simple, and locking effect is reliable, and can also play the shock-proof check effect through fastening piece, has promptly effectively avoided joint when receiving influence of vibration, because of the loosening nut loosening that causes or the phenomenon of disengaging take place at the spiral marking connection place.

Among the figure: 1, joint body; 2, loose joint nut body; 3, outer six sides; 4, flanged lip; 5, through hole; 6, butt joint rim; 7, butt hole; 8, take over; 9, seal ring.
[embodiment]
Can explain the utility model in more detail through following embodiment, the purpose of open the utility model is intended to protect all variations and the improvement in the utility model scope, and the utility model is not limited to following embodiment;
In conjunction with accompanying drawing 1～3 described a kind of locking hydraulic fitting, described joint comprises joint body 1, loose joint nut body 2, adapter 8 and seal ring 9; The butt joint thread bottom of said joint body 1 is provided with outer six sides 3 coaxial with joint body 1, and for ease of installing, said outer six sides' 3 diameter is greater than the diameter of joint body 1; Six sides, the 3 corresponding end faces that contact with loose joint nut body 2 are provided with the flanged lip 4 greater than outer six sides, 3 diameters outside; Described flanged lip 4 evenly is provided with the through hole 5 of a plurality of axle center and flanged lip 4 axis parallels; Described loose joint nut body 2 is provided with the butt joint rim 6 greater than loose joint nut body 2 diameters with the end face of outer six sides 3 corresponding contacts; Described butt joint rim 6 evenly is provided with a plurality of axle center and the butt hole 7 that docks rim 6 axis parallels; Described butt hole 7 equates with through hole 5 standard pitch diameters; Be that a plurality of butt hole 7 formed circles equate with a plurality of through hole 5 formed circular diameters; Simultaneously; The quantity of butt hole 7 has more one at least than the quantity of through hole 5, thereby is screwed to 1 last time of joint body at loose joint nut body 2, effectively guaranteed in the butt hole 7 one can with corresponding perforation in the through hole 5; For ease of making, described flanged lip 4 or butt joint rim 6 are made as circle or polygonal; Described flanged lip 4 is made as equal diameter with butt joint rim 6, thereby is more convenient for docking when mounted.
Implement the described locking hydraulic fitting of the utility model; On the flanged lip 4 of joint body 1, to establish nine through holes 5; On the butt joint rim 6 of loose joint nut body 2, establish ten butt holes 7 and be example; When progressively loose joint nut body 2 being screwed to 1 last time of joint body, because the calibration difference of through hole 5 and butt hole 7, every rotation is no more than 4 degree just can make one of them through hole 5 and one of them butt hole 7 align at least; Promptly, described joint also guaranteed to have at least a through hole 5 and butt hole 7 corresponding perforations when tightening; At this moment, run through corresponding two holes that connect and flanged lip 4 and butt joint rim 6 are tightened together, promptly effectively played mechanical locking effect with corresponding fasteners; Described fastening piece is preferably mild steel wire; As required, can with docking more through hole 5 and butt hole 7 be set respectively on the rim 6 at flanged lip 4, thereby make that one of them through hole 5 is littler with the angle of swing that one of them butt hole 7 needs when aliging, screwing force is more accurate.
Described joint not only can be used for straight coupling, and can be used in the arbitrary path joint in the multi-path joints such as threeway or four-way.
Carefully not stating in the above content is existing technology partly, does not state so run business into particular one.
