Abstract

The utility model discloses an axial elasticity hoop structure convenient to screw thread tight fit is dismantled fast, include clamp (5) constituteed by a plurality of clamps bodies (51), with clamp pad (4) of clamp (5) cooperation installation to and be used for carrying out the connecting piece fixed to clamp (5), the cross -section of the clamp body (51) is tapered, and draw -in groove (41) the cooperation that is tapered with clamp pad (4) is equally installed, a plurality of through -holes (42) have still been opened to draw -in groove (41) bottom. The utility model discloses nut part can simply be eliminated to the pressure of screw shaft shoulder end face to new utilization design, and at this moment the nut is in the unsettled state of uninstallation with screw rod component, unpacks apart and becomes equally simply convenient with screw assembly for constantly the difficult circumstances about dismantling of automatic locking is very effective under loading effect to solve screw assembly, the large -scale screw field of locking especially, and such function seems particularly important.

Description

It is easy to the axial elasticity yoke configurations that screw thread tight fit is quickly dismantled

Technical field

This utility model relates to screw-threaded coupling field, particularly relates to a kind of be easy to the axial elasticity yoke configurations that screw thread tight fit is quickly dismantled。

Background technology

The tight fit in axle and hole is generally adopted interference fit, and usual requirement on machining accuracy is higher, and associative key connection realizes torque bearing function, and assembling generally all needs to load very big extruding force, very inconvenient with instrument dismounting without professional equipment。But threaded have that processing is simple, it is convenient to assemble, and also has unidirectional carrying torque functions, if so threaded at axle with adopting in the connection in hole and realize transmission, having convenient assembling, disassembling function simultaneously。

Coordinate in motion thread assembling at actual axle with hole, in order to be able to realize big bearing function demand, thread spindle is all bigger with the scantling of the similar nut member matched, it is often all also very easily convenient to screw in when assembling, and in use can realize the constantly locking automatically of bearing capacity, thus very reliable。But when dismantling, during due to assembling, locking is very tight, dismantles very difficult, if simple easy removal can be realized under these conditions, it appears particularly important。

Utility model content

The purpose of this utility model is in that to provide one to be easy to the quick-detachable yoke configurations of screw thread tight fit, is used for solving Screw assembly continuous not easily detachable situation of auto lock under load effect。

For solving above technical problem, this utility model be the technical scheme is that a kind of to be easy to the axial elasticity yoke configurations that screw thread tight fit is quickly dismantled, and including clip, coordinates the clip pad installed with clip；The card trench bottom of described clip pad has some through holes。

Further, described clip includes several card hoop bodies, and described card hoop body is respectively arranged at two ends with mounting seat, is undertaken installing by connector and fixes。

Further, described clip body section is wedge。

Further, described clip pad is flexible plastic。

Further, described connector is bolt arrangement。

Compared with prior art, this utility model has following remarkable advantage:

1. not changing the feature of Screw assembly, only need to add clip and clip pad, low being also especially susceptible to of cost realizes；

2. clip can play good Stress decomposition effect, can strengthen the bearing capacity of structure；

3. clip pad adopts flexible plastic and card trench bottom to have through hole, it is axial elasticity design very cleverly, the Assembly And Disassembly utilizing clip realizes the tensioning of axial accessory and lax function, the effectively quick tensile force eliminating nut locking, it is achieved Screw assembly rapid and convenient dismounting tight especially。

4. clip and the wedged dress distribution structure of clip pad are easy to repeatedly quick assembly and disassembly use。

Detailed description of the invention

Below in conjunction with embodiment, embodiment of the present utility model is further described。

As Figure 1-5, a kind of it is easy to the axial elasticity yoke configurations that screw thread tight fit is quickly dismantled, form the clip 5 to opening structure including by two semicircular ring card hoop bodies 51 by bolt 6 is fixing, coordinate the clip pad 4 of installation with clip 5；The cross section of described card hoop body 51 is wedge, and the draw-in groove 41 being similarly wedge with clip pad 4 coordinates installation, and described card trench bottom also has some through holes 42 so that it is increase axial elasticity function。

Described card hoop body 51 is respectively arranged at two ends with mounting seat 52, and the installation for bolt 6 is fixed。

Described clip pad 4 is flexible plastic, and two ends are planar structure, it is simple to coordinate with shaft shoulder plane。

Application mode of the present utility model is as shown in Figure 6, card hoop body 51 uses bolt 6 to be assemblied on clip pad 4 and is integrally forming, it is inserted in after thread spindle 1 adds plain cushion 3 again and screws in nut 2, rationally all locking again, make the clip 5 on thread spindle, clip pad 4, plain washer 3 and nut 2 be formed with thread spindle 1 to be rigidly connected, reach instructions for use。

When nut 2 needs dismounting but is very difficult, with spanner, bolt 6 is pulled down, two semicircular ring card hoop bodies of cause 51 are quick is wedge shape to opening structure and card hoop body 51 cross section, easily can pry open from card hoop body mounting seat 52 with the instrument that one end is flat, clip 5 easy removal being got off, clip pad 4 returns to relaxed state。At this moment, nut 2 and the tensile force after the locking of shaft shoulder end face are completely eliminated, and make nut 2 be in vacant state completely, thus being readily disassembled。

This utility model utilizes innovative design can simply eliminate the nut member pressure to screw shaft shoulder end face, at this moment nut and screw part are in unloading vacant state, take apart and become equally simple and convenient with Screw assembly, largely effective for solving Screw assembly continuous not easily detachable situation of auto lock under load effect, particularly large-scale screw-threaded coupling field, such function is particularly important。

The foregoing is only this utility model preferred embodiment; not thereby embodiment of the present utility model and protection domain are limited; to those skilled in the art; equivalent replacement that all utilization this utility model description and diagramatic content do and the obtained scheme of apparent change should be can appreciate that, all should be included in protection domain of the present utility model。
