The utility model discloses set up gland nut and the gland nut cover mutually supported between adapter and dabber, make its loading and unloading, use more conveniently, fully solved simultaneously and then need weld the problem except that the shielded conductor on middle adapter when needing to take place axial displacement between adapter and the dabber among the prior art.
Description
Technical field
The utility model relates to a kind of logger, has related in particular to a kind of for array induction logging instrumentMandrel bindiny mechanism.
Background technology
The mandrel bindiny mechanism for connecting mandrel and tool housing in array induction logging instrument is general at presentAre all a kind of adapters that are connected with mandrel thread, this adapter is zero of the one often used of loggerPart, for array induction instrument, the effect of adapter seems particularly important. Line on instrument mandrel simultaneouslyCircle is also to form via this adapter and instrument circuit soldering of printed boards with shielded conductor.
Because applied mandrel bindiny mechanism and mandrel in existing array induction instrument are all generally to adopt screw threadConnect, therefore axial relative displacement occurs in whens mounting or dismounting between as this adapter of need and mandrel, need to rotateIntermediate transit head, but coil shielded conductor on instrument mandrel is to print via this adapter and instrument circuitMaking sheet welding, thus in the process of rotating adapter, need weldering except the shielded conductor on intermediate transit head, noShielded conductor can be disconnected by strand, and therefore, existing mandrel bindiny mechanism exists handling inconvenience, it is dumb to useEtc. defect.
Summary of the invention
Handling, use that the utility model exists for the mandrel bindiny mechanism in logger in prior artProblem, provides a kind of mandrel bindiny mechanism.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Mandrel bindiny mechanism in logger, comprises adapter, also comprise be enclosed within on mandrel and with mandrel spiral shellThe clamp nut that line connects, is arranged with on clamp nut and can mutually rotates with clamp nut and axially mutually spacingClamp nut cover, on adapter, be provided with internal thread for the end being connected with mandrel, clamp nut cover outer wallBe provided with adapter on the external screw thread of screw-internal thread fit.
By rotatably compressing nut, make to be rotatably assorted between clamp nut and clamp nut cover, thereby realizeUnder the prerequisite of all not rotating at adapter and mandrel, there is axial displacement, fully solved in prior art when needingWant, between adapter and mandrel, axial displacement occurs and need weldering asking except the shielded conductor on intermediate transit headTopic.
As preferably, clamp nut outer wall is provided with annular groove, and clamp nut cover inwall is provided with and annularGroove fit and the annular protrusion that can rotate in annular groove. By annular protrusion is snapped in annular grooveRealize axial limiting between clamp nut and clamp nut cover, can avoid clamp nut and clamp nut to be enclosed withinIn rotary course, depart from.
As preferably, clamp nut is the multidiameter shape that comprises the first hollow shaft and the second hollow shaft, the first skyExternal diameter and clamp nut cover that the external diameter of axle is less than the second hollow shaft are set in the first hollow shaft. To compressNut is designed to this kind of structure, and it is convenient to make the application of force of clamp nut, makes adapter simultaneously, compresses spiral shellConnection between mother set and clamp nut is more stable.
The utility model, owing to having adopted above technical scheme, has significant technique effect:
The utility model arranges the clamp nut and the clamp nut cover that cooperatively interact between adapter and mandrel,Fully solved in prior art when need to occur between adapter and mandrel axial displacement need weldering except inBetween the problem of shielded conductor on adapter.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of clamp nut in Fig. 1;
Fig. 3 is the structural representation of clamp nut cover in Fig. 1.
The toponym that in accompanying drawing, each number designation refers to is as follows: 1-adapter, 2-mandrel, 3-compressionNut, 4-clamp nut cover, 31-annular groove, the 32-the first hollow shaft, the 33-the second hollow shaft, 41-annular protrusion.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Embodiment 1
Mandrel bindiny mechanism in logger, as shown in Figure 1-Figure 3, comprises adapter 1, also comprises and being enclosed withinThe clamp nut 3 being threaded on mandrel 2 and with mandrel 2, is arranged with on clamp nut 3 and clamp nut 3Can mutually rotate and axial mutual spacing clamp nut cover 4 end for being connected with mandrel 2 on adapter 1Portion is provided with internal thread, clamp nut overlap 4 outer walls be provided with adapter 1 on the external screw thread of screw-internal thread fit.
Wherein clamp nut 3 outer walls are provided with annular groove 31, and clamp nut overlaps 4 inwalls and is provided with and annularGroove 31 coordinates and can be at the annular protrusion 41 of annular groove 31 interior rotations, and it is recessed that annular protrusion 41 snaps in annularIn groove 31 and can be in the interior rotation of annular groove 31, then realized clamp nut 3 and clamp nut cover 4 itBetween can mutually rotate and axial mutually spacing function.
Clamp nut 3 is the multidiameter shape that comprises the first hollow shaft 32 and the second hollow shaft 33, and first is hollowExternal diameter and clamp nut cover 4 that the external diameter of axle 32 is less than the second hollow shaft 33 are set in the first hollow shaft 32.The first hollow shaft 32 equates with the internal diameter of the second hollow shaft 33 and the first hollow shaft 32 and the second hollow shaft 33Inwall on be equipped with the internal thread being threaded with mandrel 2. The length of the first hollow shaft 32 is greater than the second skyThe length of axle 33, to ensure the length of clamp nut cover 4 in the first hollow shaft 32, thereby ensures to compressInterconnective stability between nut 3, clamp nut cover 4 and adapter 1. One side in addition, due toThe external diameter of the second hollow shaft 33 is greater than the external diameter of the first hollow shaft 32, because overlap 4 o'clock at assembling clamp nut,The end of clamp nut cover 4 can be against the ladder place of the first hollow shaft 32 and the second hollow shaft 33, thereby makesThe second hollow shaft 33 in adapter 1 outside, by active force is acted in the second hollow shaft 32 fromAnd conveniently realize the rotation of clamp nut 3.
In the present embodiment, due to clamp nut 3 and clamp nut cover 4 being set between mandrel and adapter, makeIt only need to force in clamp nut 3 in operating process, makes screw thread between clamp nut 3 and mandrel 2Rotate, can there is reverse rotation relatively in clamp nut cover 4 in rotating clamp nut 3, thereby pass throughMutual motion between clamp nut 3 and clamp nut cover 4 realizes at adapter 1 and mandrel 2 does not all rotatePrerequisite under there is axial displacement, fully solved in prior art when needing between adapter 1 and mandrel 2There is axial displacement and need the problem of weldering except the shielded conductor on adapter 1.
In a word, the foregoing is only preferred embodiment of the present utility model, allly apply for a patent according to the utility modelThe equalization that scope is done changes and modifies, and all should belong to the covering scope of the utility model patent.
