Abstract

The invention relates to an antiskid sleeve/annular spanner which can screw (unscrew) a screwing assembly (such as a bolt and a nut) and can screw (unscrew) a seriously worn screwing assembly (such as the bolt and the nut). The sleeve/annular spanner comprises a three-circular-arc part and a three-sharp-mountain part; when a good or slightly worn screwed assembly is screwed (unscrewed), the three-circular-arc part is utilized, when a seriously worn hexagon bolt/nut is unscrewed or tightly screwed, the three-circular-arc part rotates and cannot be in contact with a hexagon side face of the bolt/nut, and because a template of a limit line of the three-sharp-mountain part cannot be concentric or in parallel with a bolt, the three sharp mountain is embedded into a rib part, and the bolt rotates to be effectively screwed or unscrewed.

Description

The tool rotation can screw sleeve and the ring spanner of the solid assembly (as bolt, nut etc.) of (pine) spiral shell containing wearing and tearing

[technical field that the present invention belongs to]

This creation is about a kind of sleeve and ring spanner that tool is anti-skidding, and it consolidates assembly (as bolt, nut etc.) to screw (pine) spiral shell, and can screw the solid assembly (as bolt, nut etc.) of (pine) wearing and tearing spiral shell.

[background technology]

Mechanical engineering is the pushing hands of development of civilization from ancient times to the present always, from early stage agricultural times until cyberage, little to daily daily necessities, all need to be dependent on machinery to train, aircraft etc. greatly and produce in a large number, tradition or high-tech machinery all can be used the solid assembly of the spiral shells such as bolt, screw and nut a large amount of and that size differs, in mechanical engineering field, the instrument of the solid assembly of operation spiral shell becomes indispensable articles for use.

Sleeve in instrument and spanner are the most general and the most frequently used, and 12 jiaos of sleeve groups of commercially available traditional hexagonal and spanner group do not possess the solid assembly anti-skid sleeve of the spiral shells such as the wearing and tearing of rotation screw and nut due to it and spanner can destroy the solid assembly of the spiral shells such as screw and nut.

Therefore, possess the solid assembly sleeve of the spiral shells such as the wearing and tearing of rotation screw and nut and ring spanner and studied intensively problem by this creation.

[summary of the invention]

The main purpose of this creation is at the sleeve and the ring spanner that provide a kind to possess the solid assemblies of spiral shell such as rotation wearing and tearing screw and nut, and be to comprise: a body, its end has three-arc and tricuspid mountain conjunction.

[specific embodiment]

According to above-mentioned purpose, hereby lift preferred embodiment and coordinate graphic technological means and the effect thereof that this patent adopts that be illustrated.

Hexagonal screw socket of the present invention is not limited to the non-penetrating type sleeve, also can use at known penetration sleeve and ring spanner, and the present invention is not limited, and in this, chats in advance bright.

Three-arc 71 and tricuspid mountain 72, when screwing (pine) good spiral shell with mild wear, to consolidate assembly E be the three-arc effect, when can't contacting the solid assembly of spiral shell side, the solid assembly ER three-arc 71 of decomposition and the spiral shell that screws heavy wear makes it rotation, in this simultaneously this spacing line template in tricuspid mountain 72 because of can't be with the solid assembly of spiral shell concentric and parallel on every side, cause the tricuspid mountain to embed ER72 side flank the 17th Figure 70 and ER116, and then by this effectively rotation of bolt rotation

Refer to Fig. 1, Fig. 1 is that patent is made plane.

This is created the above-mentioned preferred embodiment of mat and is described in more detail, and only this creation is not limited to the above-mentioned embodiment given an example, all in the technological thought scope that this creation disclosed, and these structures is made various changes and modify the scope that still belongs to this creation.

Fig. 3 is this creation sleeve side perspective schematic diagram.

Fig. 4 is this creation the 2nd embodiment annular wrench floor map.

Fig. 5, for this creation the 2nd embodiment annular wrench 70P schematic diagram, is that the solid assembly E of good spiral shell that shows this conjunction rotates according to the spanner direction of rotation.

Fig. 6 implements schematic diagram for this creation the 2nd embodiment annular wrench 70P with the solid assembly ER of wearing and tearing spiral shell, system shows that the solid assembly ER three-arc 71P of spiral shell of the heavy wear of this conjunction can't contact the solid assembly of spiral shell side and make it rotation, in this simultaneously the spacing line template of this tricuspid mountain 72P because of can't be with the solid assembly of spiral shell concentric and parallel on every side, cause tricuspid mountain 72P to embed ER side flank and ER116, and then the solid assembly ER of this wearing and tearing spiral shell is rotated according to the spanner direction of rotation.

Fig. 7, for this creation the 2nd embodiment annular wrench the 12nd figure partial enlarged drawing, is the solid assembly contact assembly side ER116 of spiral shell that shows the heavy wear of this conjunction, with the clamped schematic diagram of sharp side 72ER.

Fig. 8 implements schematic diagram for this creation embodiment impact wrench 70 with the solid assembly ER of wearing and tearing spiral shell, system shows that the solid assembly ER three-arc 71 of spiral shell of the heavy wear of this conjunction can't contact the solid assembly of spiral shell side and make it rotation, in this simultaneously the spacing line template of this tricuspid mountain 72P because of can't be with the solid assembly of spiral shell concentric and parallel on every side, cause tricuspid mountain 72 to embed ER side flank and ER116, and then the solid assembly ER of this wearing and tearing spiral shell is rotated according to the spanner direction of rotation.

Fig. 9 implements to show side schematic view with the solid assembly ER of wearing and tearing spiral shell for this creation embodiment impact wrench 70, is to show that the solid assembly ER contact of spiral shell of heavy wear of this conjunction is because of mutual decentraction, and not parallel spiral shell assembly side admittedly makes it to embed schematic diagram.

Figure 10 implements to show floor map with the solid assembly ER of wearing and tearing spiral shell for this creation embodiment impact wrench 70, is to show that the solid assembly ER contact of spiral shell of heavy wear of this conjunction is because of mutual decentraction, and not parallel spiral shell assembly ER116 side admittedly makes it to embed schematic diagram.

Figure 11 implements to show the local enlarged diagram in plane for this creation embodiment impact wrench 70 with the solid assembly ER of wearing and tearing spiral shell, system shows that the solid assembly ER of spiral shell of the heavy wear of this conjunction contacts because of mutual decentraction, and the solid assembly ER116 of not parallel spiral shell side makes it to embed the ER72 schematic diagram.
