Description
Technical field
The present invention relates to electric power tool field more particularly to a kind of extracting tools of anti-nut skid-falling threaded spindle cap nut.
Background technique
Key position on the big machineries such as the heavy constructions such as bridge and automobile is needed commonly using bolt, these key portions
The stress of position haves the characteristics that load is big and shock loading is more, and it is even sliding that these features cause the nut on bolt to be easy loosening
It is de-, it causes the accident.It if nut is welded on screw rod, ensure that nut will not slip, but needed when maintenance
When dismantling nut, it but will appear the inconvenient problem of nut disassembly.Therefore there are nuts to use for the bolt of the prior art
It is easy to slip in journey, is although not easy slippage when nut to be welded on bolt but can have nut and not allow quick detachable lance
Shield.
As shown in Figures 2 to 6, a kind of existing anti-nut skid-falling bolt, comprising: bolt；The bolt includes: bolt head 2
With screw rod 1；Described 1 one end of screw rod is fixedly connected on bolt head 2；1 surface of screw rod is provided with mounting hole 101, mounting hole 101
It is vertical with 1 central axes of screw rod；The anti-nut skid-falling bolt further include: flexible clamp piece 4；The flexible clamp piece 4 includes clamp
403, guide rod 402 and elastic mechanism 401；Described 402 one end of guide rod is fixedly connected with clamp 403, and the other end is fixedly connected with elastic machine
Structure 401, elastic mechanism 401 and guide rod 402 are inserted into mounting hole 101, prominent 1 surface of screw rod of clamp 403；The elastic mechanism
401 one end opposite with 402 junction of guide rod are contacted with 101 bottom hole of mounting hole, and 401 elastic force direction of elastic mechanism is by mounting hole
It is directed toward outside mounting hole 101 in 101；The clamp 403 towards 2 side of bolt head be the face vertical with 1 central axes of screw rod, with bolt head
2 opposite sides are inclined-plane or spherical surface.
The mounting hole 101 further includes block 102；The block 102 is fixedly connected on orifice edge, block 102 and peace
The spacing filled between the side on 101 aperture of hole corresponding thereto is less than 402 diameter of guide rod；402 upper surface of guide rod is under block 102
Mounting hole 101 in.
When nut 3 is tightened, nut 3 is rotated along screw rod 1 to be moved towards bolt head 2, when nut 3 encounter on clamp 403 with spiral shell
When the opposite inclined-plane or spherical surface of bolt head 2, nut 3 will have a downward pressure to clamp 403, and nut 3 passes through inclined-plane or ball
Clamp 403 is pressed into mounting hole 101 by face, it is only necessary to and the Fast Installation as plain nut can be realized in rotary nut 3,
When nut 3 is loosened by external force, the clamp 403 of flexible clamp piece 4 exposes 1 surface of screw rod, hangs down on clamp 403 with central axes
Straight face nut 3 is blocked make nut 3 not further towards and bolt head 2 with respect to another end motion of screw rod 1, when needing to dismantle nut
Clamp 403 can be pressed into when 3 after being allowed in mounting hole 101 and exit nut 3, the present invention can guarantee nut 3 in use
It, also can easy removal in disassembly while slippage.In use, guide rod 402 is blocked in the mounting hole under it by block 102
In 101, avoiding guide rod 402 from stretching out 1 surface of screw rod tighten nut 3 cannot by the blocking of guide rod 402 when tightening, moreover it is possible to avoid
Flexible clamp piece 4, which skids off mounting hole 101, leads to safety problem.
But this nut 3, due to the blocking of flexible clamp piece 4, is unable to direct image plain nut and equally dismantles in disassembly, needs
Bolt could be back-outed as plain bolt by first flexible clamp piece 4 being pressed into after mounting hole 101, but flexible clamp piece 4 is pressed into and is pacified
Fill hole 101 the problem is that, if pushing down flexible clamp piece 4 using rod piece, in rotary nut 3 nut 3 can by rod piece support holds,
Flexible clamp piece 4 is after rod piece is supported and opened since top its clamp 403 that do not stress just will pop up 1 surface of screw rod.Therefore elastic card
Part 4 there are problems that being difficult to be pressed into mounting hole 101.
Summary of the invention
The technical problem to be solved by the present invention is a kind of extracting tool of anti-nut skid-falling threaded spindle cap nut is provided, to solve
The above problem.
The technical scheme is that a kind of extracting tool of anti-nut skid-falling threaded spindle cap nut,
The extracting tool of the anti-nut skid-falling threaded spindle cap nut includes:
Supporter and cap body；
The supporter is semicylinder, the shape that the vertical plane and block that supporter diameter is less than clamp towards bolt head direction surround
Shape；
The cap body is 1/4 spherical shape that diameter and supporter match, and one face of cap body is overlapped with support bodyside plan, and cap body is another
An outer face is overlapped and is fixedly connected with supporter one end；
The sum of length of supporter and cap body is equal to clamp length.
The supporter and cap body have magnetism.
The beneficial effects of the present invention are:
Compared with prior art, the present invention is by the way that extracting tool side plane to be bonded with the vertical plane in clamp towards bolt head direction,
Supporter bottom surface is contacted with guide rod upper surface, the cap body of nut contact extracting tool when cap rotation, since cap body is spherical surface, spiral shell
Cap, which will apply a downward power to extracting tool, makes extracting tool that flexible clamp piece is pressed into mounting hole, to enable nut picture
The same easy removal of plain nut, the present invention is easy for installation, using simple.
