Abstract
The invention discloses a bolt capable of being taken out rapidly after being broken. The bolt comprises a bolt head and a screw rod integrally formed with the bolt head. A through hollow cavity is formed from the end of the bolt head to the end of the screw rod. The cross section of the hollow cavity is in a hexagonal shape. The bolt further comprises a center rod. The center rod comprises a center rod head with the section identical with that of the bolt head and a center rod pillar with the section identical with that of the wall of the hollow cavity. The center rod pillar is in sliding fit with the hollow cavity, and the center rod head is attached to the bolt head in a sealed manner. The bolt has the beneficial effects that the bolt is applied to connection of objects, when the bolt breaks, the broken bolt can be rapidly taken out through a hexagon wrench, and the time for taking out the bolt is effectively saved.
Description
Technical field
The present invention relates to a kind of bolt, be specially the bolt that a kind of energy to failure is taken out fast.
Background technique
Bolt is a kind of common mechanical parts, be made up of bolt head and screw rod two-part, bolt head outer wall is arranged to polygonal as required, modal is Hexagon bolt head, screw portion is provided with screw thread, time bolt uses, two articles is connected by bolt, its in essence bolt be for being fastenedly connected two parts with through hole, be widely used at mechanical field, but in actual mechanical process, there will be following problem, the bolt fixed, be exposed to outside part usually surprisingly to be severed by other objects, cause and the remaining screw rod of bolt is still fixed in tapped through hole, the mechanical assembly fixed is caused to dismantle smoothly, usual people can use destructive method therefrom to be got out by screw rod, such operation is not only wasted time and energy, and will the internal thread of through hole be destroyed, the fixed structure of mechanical assembly is indirectly made to lose efficacy.
Summary of the invention
The object of the invention is to: a kind of bolt that can take out fast when unexpected fracture is provided.
For achieving the above object, the base case that the application provides is: the bolt that energy to failure is taken out fast, comprise bolt head and screw rod one-body molded with bolt head, be provided with the hollow cavity run through to screw rod end from bolt head end, the cross section of described hollow cavity is Hexagon, also comprise center-pole, described center-pole comprises the center-pole head identical with bolt head cross section and the cross section center roofbolt identical with hollow cavity wall, described center roofbolt and hollow cavity are slidably matched, center-pole head and bolt head gluing, sealing.
The advantage of this programme is: 1, bolt head end is provided with the hollow cavity run through to screw rod end, and the cross section of hollow cavity is Hexagon, works as bolt fracture, directly uses six prism spanners, is taken out by the bolt broken.2, be the resistance to flexure ensureing bolt, fill center-pole in using process in hollow cavity, center-pole comprises center-pole Tou He center roofbolt, and center roofbolt is inserted in hollow cavity, strengthens the bending resistance of bolt shank.Center-pole head and bolt head gluing, sealing ensure that the sealing of hollow cavity, make pollutant can not enter into hollow cavity from bolt head.
Scheme two, based on scheme preferred, the circumscribed circle diameter of described hollow cavity is 4mm, after center-pole post takes out, directly insert hexagon wrench, be inserted in hollow cavity and take out, convenient and swift, and select 4mm, be conducive to the hexagon wrench that different model uses same model.
Scheme three, as the optimization of scheme two, described center roofbolt is outside equipped with one deck sealing layer, due to bolt meeting and combination with oxygen in water and air in most installation environment, arrange one deck sealing layer at center-pole column outer wall, preventing pollution thing produces corrosion to center-pole post and hollow cavity wall.
Scheme four, as the optimization of scheme three, described sealing layer is bar shaped silicone band, will be sealed by center roofbolt when sealing by being wound around, when fracture appears in bolt, the bar shaped silicone band be wrapped on the roofbolt of center has elasticity, can be conducive to taking off from the center roofbolt of fracture, makes center roofbolt and screw rod form space, by magnet by center roofbolt sucking-off, hollow cavity is non-filler again, directly uses hexagon wrench, can screw out the screw rod of fracture.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of the bolt that energy to failure of the present invention is taken out fast;
Fig. 2 is the partial sectional view of the bolt that invention energy to failure is taken out fast.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference character in Figure of description comprises: center-pole head 11, center roofbolt 12, bolt head 21, screw rod 22, hollow cavity 23, sealing layer 3.
Embodiment is substantially as shown in Figures 1 and 2: the bolt that energy to failure is taken out fast, comprise bolt head 21, screw rod 22 integrated with bolt head 21, be provided with the hollow cavity 23 run through to screw rod 22 end from bolt head 21 end, the cross section of hollow cavity 23 is Hexagon, the circumscribed circle diameter of hollow cavity 23 is 4mm, the bolt of this programme also comprises center-pole, center-pole comprises the center-pole head 11 identical with bolt head 21 cross section and the cross section center roofbolt 12 identical with hollow cavity wall, center roofbolt 12 and hollow cavity 23 are slidably matched, center-pole head 11 and bolt head 21 gluing, sealing.
Center roofbolt 12 is outside equipped with one deck sealing layer 3, because bolt is in most installation environment, for reaching antirust object, one deck sealing layer 3 is set at center roofbolt 12 outer wall, center roofbolt can be intercepted and touch oxygen and moisture, effectively prevent center roofbolt 12 and the corrosion of hollow cavity 12 wall.
Sealing layer 3 is bar shaped silicone band, center roofbolt 12 is sealed by being wound around when sealing, when fracture appears in bolt, the bar shaped silicone band be wrapped on center roofbolt 12 has elasticity, is conducive to taking off from the center roofbolt 12 of fracture, makes center roofbolt 12 and screw rod 22 form space, by magnet by center roofbolt 12 sucking-off, non-filler again in hollow cavity 23, directly uses hexagon wrench to insert in hollow cavity, can screw out the screw rod of fracture.
Bolt adopts the manufacture technics of casting, casting mould with the use of under, form the Hexagon hollow cavity 12 of bolt, again to screw rod 22 threading of bolt blank after casting, final formation has the bolt of Hexagon hollow cavity, the manufacture of center-pole completes by stamping process, is coordinated by center-pole with the bolt with hollow cavity, and by glue by bolt head 21 and the sealing of center-pole head 11 joint place.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in specification etc. record the content that may be used for explaining claim.
