Background technique
Locking, anti-theft bolt that prior art relates to, mostly complex structure, member is many, processing is inconvenient.And the antirust function that does not possess double thread portion.And that antirust bolt does not possess is antitheft.This is the drawback of prior art.
Summary of the invention
The purpose of this invention is to provide a kind of antitheft locking antirust bolt component and removal tool special, solve antitheft locking purpose by the tight mode of friction contract, mode by sealing solves antirust purpose, reach the purpose of dismounting by removal tool special, thereby filled up the blank of prior art.
The present invention includes: 1, three-prevention bolt, 2, extracting tool two-part constitute.
Description of drawings
Accompanying drawing one is a combination embodiment of the present invention.By accompanying drawing describe the present invention it is characterized in that three-prevention bolt 1 by nut 3. screw rod 1. tighten up workpiece, 2. realize three anti-functions by the chock plug sleeve, 2. extracting tool 2 cooperates with the chock plug sleeve of three-prevention bolt 1, is used to dismantle three-prevention bolt 1.
Embodiment
The present invention is achieved in that three-prevention bolt 1 by 1. screw rod, 2. chock plug sleeve, and 3. nut three parts constitute.It is characterized in that the chock plug sleeve 2. by the tight chock plug of interior contract 4. be pressed into screw rod 1. the center the tight circular hole of contract 5. in and nut 3. go up, and with screw rod 1. nut 3. agree with and constitute fastening assembly structure; 6. extracting tool 2 by pitching the pawl sleeve, 7. quill, and 8. handle sleeve, 9. the drill drift bolt constitutes.6. 10. the inner arc surface and the Rotary-table exterior arc surface contract 2. of the chock plug sleeve on the three-prevention bolt 1 of part is tight by the fork pawl to it is characterized in that pitching the pawl sleeve, pipe thread on cylindrical system and the quill interior round standard thread in 7. is to cooperate, 8. realize turn with quill interior cover hole structure 7. by the handle sleeve then, thereby extract the chock plug sleeve 2. by fork pawl sleeve is 6. up.Reach the purpose of dismounting.Three-prevention bolt 1 is used for fastening workpiece, plays a part antitheftly, locking, antirust, and 2 of extracting tools are specifically designed to dismounting three-prevention bolt 1, can also use as general extracting tool simultaneously.
Being further described by embodiment and the invention is characterized in that 5. screw rod threaded end 1. is equipped with the tight circular hole of contract vertically, also can be hexagon ring, tri-angle-holed, the polygonal hole body.Chock plug sleeve tube wall 2. is the Rotary-table tubular that single head is big, the mouth of pipe is little.Inner orifice be arranged to circle hole shape, also can be according to nut profile setting 3..Being equipped with the tight chock plug of garden shape contract 4. by in the one end pipe of termination, also can be hexagon chock plug, triangle chock plug, the polygonal chock plug.5. 4. the tight chock plug of contract constitute the contract drive fit with the tight circular hole of contract.Nut hexagonal is 3. made the tight circular arc of contract.Be convenient to constitute the contract drive fit with chock plug sleeve inner arc surface 2..Antitheft be by the chock plug sleeve 2. the tight chock plug of contract 4. with the tight circular hole of screw rod contract 1. 5. reach nut 3. tight stiction and the chock plug sleeve of tight fit shapes, the contract of contract 2. realize with tapering, smooth cylindrical shape, therefore be difficult to dismounting by general instrument, must dismantle by special tool.Thereby reach antitheft purpose.Contract drive fit stiction is big more, and anti-theft effect is strong more, and the size of stiction is set by adjusting the tight section of contract interference fit degree.But the stiction that maximum static friction force produces in the time of must not surpassing the extracting tool dismounting is advisable.Change the chock plug sleeve tapering 2. and the size of the stiction of surface roughness can adjust dismounting the time, locking is 4. to realize with contract drive fit or the fit shapes that 5. the tight circular hole of screw rod contract 1. reaches nut contract 3. tight garden cambered surface or six aspects by the tight chock plug of chock plug sleeve contract 2..Antirust is to be coated with butter in 2. reaching with the nut sealing that is constituted 3. by the chock plug sleeve to realize.
Extracting tool 2 be as with the supporting special tool of three-prevention bolt 1, be mainly used in the device of assembling and dismounting.6. extracting tool 2 by pitching the pawl sleeve, 7. quill, and 8. handle sleeve, 9. the drill drift bolt constitutes.10. fork pawl sleeve big first end 6. makes the fork pawl, can be three claw types, four paws shape, also can make multijaw shape as long as guarantee under the condition of big as much as possible conjunction surface.Fork pawl exterior arc surface 10. is provided with pipe thread, and microcephaly's one end end face is provided with interior trepanning (11) and 9. screw is equipped with the drill drift screw rod.Be provided with standard thread in the quill pipe 7..Tube mouth section leaves the high hardness reaming section of protection screw thread, and end face is provided with handle sleeve major part trepanning 8..The interior trepanning face of handle sleeve major part section is 8. formulated according to nut profile 3., and outer hole face is then formulated according to the shape of quill top trepanning 7..Being generally hexagon, also can be polygon.10. the inner arc surface and the Rotary-table exterior arc surface contract 2. of the chock plug sleeve on the three-prevention bolt 1 of part is tight to it is characterized in that pitching pawl sleeve fork pawl 6., pipe thread on cylindrical system and the quill interior round standard thread in 7. is to cooperate, then by the handle sleeve 2. stub end cooperate with quill interior external trepanning 7. the realization turn, pull up the chock plug sleeve 2., back out nut 3. by handle sleeve stub end 2. at last, pulling down the chock plug sleeve 2. is that 9. the 2. little head end of armrest sleeve tube cooperates dismounting with the drill drift bolt, and the swivel nut hole cooperates dismounting in pulling down fork pawl sleeve and 6. be armrest sleeve tube 2. the microcephaly holding external thread sleeve and pitches pawl sleeve termination 6..Thereby achieve the goal.
