Abstract
A kind of pipeline self-locking connection structure, it is characterized in that: pipeline one and outside cone joint welding, pipeline two is assembling after cap nut pipeline two and flat ozzle welding, and elastic force ratchet is arranged on and on cap nut, is completed ratchet and install by ratchet mounting groove, the screw thread of cap nut and outside cone joint forms pipeline jointing construction, after pipe joint installation, rely on the resilient engagement of elastic force ratchet and ratchet, rotatablely moving of restriction cap nut and flat ozzle, the motion thereby the screw thread rotation that has limited cap nut and outside cone joint gets loose, form self-locking tube union mechanism.The pipeline self-locking connection structure that the utility model provides, make engine pipelines possess self-locking linkage function, cancel the tight mode of traditional locking wire lock, save the troublesome operation of dismounting lock silk, simplify the structure, this kind of new structure strengthened the reliability that pipeline connects simultaneously, can obviously improve assembling and the maintainability of pipeline.
Description
Technical field
The present utility model relates to aeroengine field, and a kind of pipeline self-locking connection structure is provided, and the self-locking that this structure also can be used for other field pipeline connects.
Background technique
The function of engine pipelines is delivering fuel, lubricating oil, air and engine condition control information, is the important composition parts of motor.Engine pipelines is laid in the limited space of external engine more, needs to meet to connect sealing and wait requirement the work that simultaneously can be satisfied with in broad complicated operating mode in order to ensure motor, reliable lock that need consideration pipeline joint.
Conventional construction, as shown in Figure 1, need to prevent the thread connecting joint destruction sealing configuration that occurs getting loose by lock silk, and locking wire lock is tightly a design lock silk hole on the corresponding part in pipe joint two ends, after tightening and assemble, refills and joins locking lock thread.This kind of locking disconnecting prevention structure, need to rely on the motion that gets loose of lock silk limiting joint two end nuts, to the higher requirement that is equipped with of lock silk, assembly direction is incorrect can not lock anticreep for lock silk, lock silk can not assemble tension or excessively loose, the easily fracture in engine working process of lock silk tension, lock silk is crossed pine can not play corresponding effect, lock silk needs special instrument assemble and decompose simultaneously, and the dismounting of lock silk wasting time and energy very, can not meet the requirement of motor to assembling, maintainability.
For this reason, need the pipe joint self-locking connection structure of a kind of model utility of invention, realize the reliable self-locking of pipeline jointing construction, improve assembling and maintainability simultaneously.
Model utility content
The purpose of this utility model is to provide a kind of Novel pipeline self-locking connection structure, there is compact structure, install and remove convenient, can for pipeline connect provide high efficient and reliable self-locking connect.
The technical solution of the utility model is: a kind of pipeline self-locking connection structure, it is characterized in that, pipeline 1 welds with outside cone joint 2, pipeline 28 welds pipeline 28 and flat ozzle 3 having assembled after cap nut 5, and elastic force ratchet 7 is arranged on and on cap nut 5, is completed ratchet and install by ratchet mounting groove 6, the screw thread of cap nut 5 and outside cone joint 2 forms pipeline jointing construction, after pipe joint installation, rely on the resilient engagement of elastic force ratchet 7 and ratchet 4, restriction cap nut 5 rotatablely moves with flat ozzle 3, the motion thereby the screw thread rotation that has limited cap nut 5 and outside cone joint 2 gets loose, form self-locking tube union mechanism.
Wherein ratchet mounting groove 6 is arranged on the groove structure of cap nut 5 internal faces, and plural radially convex is set, and plays the effect of axial constraint elastic force ratchet 7, at a place, opening is set, and plays the effect of circumferential constraint elastic force ratchet 7.
Its elastic force ratchet 7 is the open annular structure that comprise two ratchets, and is provided with a crimping perk in a side corresponding to opening, and this perk coordinates with the opening of ratchet mounting groove 6, and its feature is that elastic force ratchet 7 can change.
The wherein chamfering angle size difference between easily tight adjacent two cams of difficult loose ratchet 4, the chamfering R1 that screws direction is greater than the chamfering R2 of rotational direction, makes the assembling moment of cap nut 5 be less than decomposition moment, forms Yi Jinnansong mechanism.
Advantage of the present utility model: pipeline has self-locking linkage function; Replace traditional tight mode of locking wire lock, strengthened the reliability that pipeline connects; Self-locking structure can be reused continuously, does not need the each expendable of lock silk to use, and has alleviated the working strength of dismounting, has improved efficiency, has strengthened assembling and the maintainability of motor.

Embodiment
A kind of pipeline self-locking connection structure, comprise ratchet install, from locking pipe joint, be specially:
Ratchet is installed: elastic force ratchet 7 elastically deformables are arranged in the ratchet mounting groove 6 of cap nut 5, when elastic force ratchet 7 is in place, due to the distending of elastic force ratchet 7, by the axial motion of axial limit structure 1 and axial limit structure 2 11 restriction elastic force ratchets 7, limit the circumferential movement of elastic force ratchet 7 by circumferential limit structure 10 simultaneously, complete the mounting limit of elastic force ratchet 7, elastic force ratchet 7 and cap nut 5 are installed as to one.
From locking pipe joint: pipeline 1 welds with outside cone joint 2, pipeline 28 welds with flat ozzle 3, the screw thread of cap nut 5 and outside cone joint 2 forms pipeline jointing construction, elastic force ratchet 7 is arranged on cap nut 5 by ratchet mounting groove 6, relies on elastic force ratchet 7 and the resilient engagement of easily tight difficult loose ratchet 4 to form self-locking tube union mechanism.
Its feature is replaceable: elastic force ratchet 7 is arranged on cap nut 5 by resiliently deformable, this process is reversible, can shake off by tightening up elastic force ratchet 7 axial restraint of axial limit structure 1 and axial limit structure 2 11, from axial decomposition elastic force ratchet 7, complete the replacing of elastic force ratchet 7.
Its feature is easy tight difficult pine: the ratchet 4 on flat ozzle 3 screws and the ratchet unscrewed varies in size, be R1>R2, rely on elastic force ratchet 7 to screw and unscrew the difference of resiliently deformable, make the assembling moment of cap nut 5 be less than decomposition moment, form Yi Jinnansong mechanism.
