Abstract

The utility model discloses a clamp convenient to screw thread tight fit is dismantled fast, including a plurality of clamp body (3) to and be used for carrying out the connecting piece fixed to the clamp body (3), the cross -section of the clamp body (3) is tapered. The clamp body (3) both ends are equipped with mount pad (31) respectively for the installation of connecting piece is fixed. The connecting piece is bolt (4) structure. 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

A kind of it is easy to the clip 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 clip 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 relatively big with the scantling of the similar nut member matched, and 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 it is very reliable, but when dismantling, assembling is very tight often, 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 providing a kind of is easy to the clip that screw thread tight fit is quickly dismantled, and is used for solving Screw assembly continuous not easily detachable situation of auto lock under load effect, is specifically for use in the convenient dismounting after Large-scale thread locking.

For solving above technical problem, this utility model be the technical scheme is that a kind of to be easy to the clip that screw thread tight fit is quickly dismantled, it is characterised in that includes several card hoop bodies and the connector for card hoop body is fixed；The cross section of described card hoop body is wedge.

Further, described card hoop body is respectively arranged at two ends with mounting seat, and the installation for connector is fixed.

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 nut and the shaft shoulder need to carry out chamfered and add clip assembling, low being also especially susceptible to of cost realizes；

2. the two ends conical surface closes up clip design very cleverly, utilizes the Assembly And Disassembly of clip to realize 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.

3. the wedged dress distribution structure of clip is 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 shown in Figure 1-2, a kind of it is easy to the clip that screw thread tight fit is quickly dismantled, forms opening structure including by two semicircular ring card hoop bodies 3, coordinate the clip pad 4 installed and the bolt 4 for card hoop body 3 is fixed with clip 5；The cross section of described card hoop body is wedge.

Described card hoop body 3 is respectively arranged at two ends with mounting seat 31, and the installation for bolt 4 is fixed.

Application mode of the present utility model, as it is shown on figure 3, clip 3 cross section is wedge shape, is formed opening structure by two semicircular ring card hoop bodies, and it is cone structure that clip closes up two ends, it is simple to coordinate with the shaft shoulder, nut fillet surface.

Clip 3 uses bolt 4 to be assembled into one, is inserted in thread spindle 1 and screws in nut 2 more rationally all locking, makes the clip on thread spindle, nut and axle be formed and be rigidly connected, reach instructions for use.

When nut 2 needs dismounting but is very difficult, with spanner, bolt 4 is pulled down, two semicircular ring card hoop bodies of cause are quick is wedge shape to opening structure and clip body section, easily can pry open from card hoop body junction with the instrument that one end is flat, clip easy removal is got off, make the tensile force after the locking of nut 2 and the shaft shoulder conical surface be completely eliminated, make nut be in vacant state completely and be especially susceptible to dismounting.

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.
