Abstract

The invention discloses a kind of extra large tooling for fastener, including nut body, the nut body includes the screw hole for fitted bolt, screw hole connects a torsional spring mounting hole, torsional spring is set in the torsional spring mounting hole, the first slot is longitudinally offered in the nut body, the one end is fixed in the torsional spring mounting hole, torsional spring other end setting one connecting rod of connection, the connecting rod is stretched into first slot, the second slot for connecting first slot is connected on the side wall of the nut body, the connecting rod has the end for stretching out second slot.The present invention is when dismantling nut, it is only necessary to common wrench is placed on nut, the end for stretching out the connecting rod of the second slot of nut at this time is abutted against by spanner, and torsional spring is set so as to which connecting rod be driven to twist so that the frictional force between torsional spring and the bolt of attaching nut reduces.Therefore nut can be dismantled normally at this time.

Description

A kind of sea tooling is for fastener
Technical field
The present invention relates to fastener areas, more particularly to clamp nut.
Background technology
General nut use process vibration etc. it is other due to can voluntarily loosen, such as vibrate, it is this existing to prevent As then just having invented self-locking nut.Its function of self-locking nut is mainly locking, antivibration.For special occasions.Its work is former Reason is usually frictionally self-locking.General self-locking nut usually requires special tool(s) or other devices to make it possible to remove spiral shell It is female.
Invention content
For the deficiencies in the prior art, the present invention provides a kind of extra large tooling for fastener.
The present invention is achieved through the following technical solutions:A kind of sea tooling is for fastener, including nut body, the spiral shell Maternal body includes the screw hole for fitted bolt, and screw hole connects a torsional spring mounting hole, torsional spring is set in the torsional spring mounting hole, The first slot is longitudinally offered in the nut body, the one end is fixed in the torsional spring mounting hole, and the torsional spring is another One end setting one connecting rod of connection, the connecting rod are stretched into first slot, are connected on the side wall of the nut body The second slot of first slot is connected, the connecting rod has the end for stretching out second slot.Above structure, in dismounting nut When, it is only necessary to common wrench is placed on nut, the end for stretching out the connecting rod of the second slot of nut at this time is abutted against by spanner, so as to Connecting rod is driven to twist and sets torsional spring so that the frictional force between torsional spring and the bolt of attaching nut reduces.Therefore nut can be at this time Normally dismantled.
In above-mentioned technical proposal, the height that second slot is stretched out in the end is 0.5 ~ 2mm.First slot and described There is gap between connecting rod.Above-mentioned technical proposal when being abutted against in end by spanner, can retract in the second slot, at this time torsional spring It has been loosened.
In above-mentioned technical proposal, the connecting rod and the torsional spring are integrally formed, therefore can be by bending tool by one Root steel complete the processing of the integral piece of torsional spring and connecting rod, substantially reduce process time.
The present invention has the advantages that:Self-locking nut of the present invention can complete self-locking nut by general wrench Dismounting, and it is simple in structure, and production is very convenient.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the schematic top plan view of the present invention.
Fig. 3 is the schematic side view of the present invention.
Specific embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings:It is a kind of referring to Fig. 1 to Fig. 3 Extra large tooling is for fastener, and including nut body 1, the nut body 1 includes the screw hole 10 for fitted bolt, and screw hole 10 connects One torsional spring mounting hole 11, the setting torsional spring 2 in the torsional spring mounting hole 11,
The first slot 3 is offered in 1 longitudinal direction of nut body, 2 one end 2a of torsional spring is fixed on the torsional spring mounting hole In 11,2 other end 2b of torsional spring setting one connecting rod 4 of connection, the connecting rod 4 is stretched into first slot 3, referring to Fig. 2, Connecting rod 4 abuts against the right end position of the first slot 3.
The second slot 5 for connecting first slot 3 is connected on the side wall of the nut body 1, the connecting rod 4 has The end 4a of second slot 5 is stretched out, see also Fig. 2, when connecting rod abuts against 3 right end position of the first slot, end 4a Also 5 right end position of the second slot is abutted against(End is abutted against by spanner during this state).Also shown in Fig. 2 end 4a not by Illustrated position when spanner abuts against, at this time end 4a be represented by dashed line.
When dismantling nut, it is only necessary to common wrench is placed on nut, stretches out the connecting rod of the second slot of nut at this time End is abutted against by spanner, sets torsional spring so as to which connecting rod be driven to twist so that the frictional force between torsional spring and the bolt of attaching nut subtracts It is small.Therefore nut can be dismantled normally at this time.
The height that the end 4a stretches out second slot 5 is 0.5 ~ 2mm.Between first slot 3 and the connecting rod 4 With gap 3a.When being abutted against in end by spanner, it can retract in the second slot, torsional spring has been loosened at this time.
The connecting rod 4 and the torsional spring 2 are integrally formed, therefore can be completed to turn round by a steel by bending tool The processing of spring and the integral piece of connecting rod, substantially reduces process time.
The advantages of basic principle, main feature and the utility model of the utility model has been shown and described above.One's own profession The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description Only the utility model principle, on the premise of not departing from the spirit and scope of the utility model the utility model also have respectively Kind changes and improvements.Above-mentioned changes and improvements are both fallen in claimed the scope of the utility model.
