Description
Technical field
This utility model relates to hardware technical field, especially relates to a kind of afterbody self sealss check bolt.
Background technology
Bolt is a kind of cylindrical threaded securing member, is also often called screw.Can be directly used in plant equipment, it is possible to nut adapted.Traditional bolt is directly overall adopts metal structure, in use, directly adopts threaded engagement to lock with nut or part.But traditional bolt is in use, being usually used on the parts taking regular exercise or shaking, bolt easily produces to loosen after a long time use, it is easy to what it is such that locking member is locked is firm not.
Utility model content
This utility model is intended to provide a kind of easy to use, after a procedure can auto lock, it is prevented that loosening connection retention device.
Connection retention device in this programme, including pad, two bolts and two nuts, wherein bolt includes screw head, stud；Described screw head is one-body molded with stud head, the afterbody of described stud is provided with the diameter multidiameter less than stud head diameter, described multidiameter is arranged with the sleeve pipe that diameter is consistent with stud head diameter, the external diameter surface processing of described stud and sleeve pipe has integrated external screw thread, and described sleeve pipe uses gum elastic to make；Described pad includes shim body, and described shim body is provided with mean for a waist-shaped hole and a hexagon ring of bolt traverse；The end face of described nut body is provided with rubbing surface.
Adopt the technical solution of the utility model, have the following technical effect that
1, when bolt uses, described cannula portion branch produces bigger deformation, and the stud of metal is produced elastic force, and so when the part movement or the vibrations that use this bolt, stud directly will be produced elastic reaction by described sleeve pipe, it is prevented that it loosens.And sleeve pipe can produce bigger elastic deformation, directly screwed hole can be sealed, so use this bolt will enhanced convenience under needing the environment sealed, it is not necessary to use other sealing structure, simultaneously because whole jacket exterior is all sealing surface, sealing effectiveness is better.Due to this bolt fastened time, sleeve pipe also can produce bigger deformation so that the overall twisting resistance of this bolt not only acts on several screw threads of stud head, so makes the lashing force that bolt can bear bigger.
2, have additional rubbing surface at the end face of nut, so installing and using one bigger frictional force of existence between back nut and contact surface, thus being in Long-term Vibration environment at connector, not easily loosening, reaching locking purpose.At dismountable, as long as adopting spanner to overcome gmatjpdumamics to be disassembled smoothly, therefore this utility model has a good anti-loosing effect, and has simple in construction, reliably, does not need specific purpose tool, the advantages such as suitable environment is extensive during installation；Design is without the requirement of special technique parameter simultaneously, it is simple to the advantage of manufacture.
3, two bolts realize interlocking by pad, also reach locking effect.
Further, helicitic texture is adopted to be connected between described sleeve pipe and multidiameter.
Adopt helicitic texture, easy disassembly sleeve pipe and multidiameter.
Further, described pad is located between sleeve pipe top and stud stepped locations.
Described pad can be clamped between sleeve pipe top and stud stepped locations, connects more stable.
Further, described rubbing surface is ratchet structure, and described ratchet is helical teeth.
Selecting ratchet structure, coefficient of friction is higher.

Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
The present embodiment connection retention device, including pad, two bolts and two nuts.As it is shown in figure 1, bolt, it includes screw head 1, stud 2；Described screw head 1 is one-body molded with stud 2 head, the afterbody design of described stud 2 has the diameter multidiameter 21 less than head diameter, described multidiameter 21 is enclosed with the sleeve pipe 3 that diameter is the same with stud 2 head diameter, the external diameter surface processing of described stud 2 and sleeve pipe 3 has integrated external screw thread, and described sleeve pipe 3 uses resilient nonmetallic material to make.
This bolt is when specifically making, and the blank of described screw head 1, stud 2 one is first produced, and then the blank of sleeve pipe 3 is wrapped in described multidiameter 21, finally carries out external screw thread processing.
When this bolt uses, described sleeve pipe 3 part can produce bigger deformation, and the stud 2 of metal is produced elastic force, and so when the part movement or the vibrations that use this bolt, stud 2 directly will be produced elastic reaction by described sleeve pipe 3, it is prevented that it loosens.And sleeve pipe 3 can produce bigger elastic deformation, can directly screwed hole be sealed, so use under the environment needing sealing this bolt will enhanced convenience, simultaneously because whole jacket exterior is all sealing surface, sealing effectiveness is better.
Due to this bolt fastened time, sleeve pipe also can produce bigger deformation so that the overall twisting resistance of this bolt not only acts on several screw threads of stud head, so makes the lashing force that bolt can bear bigger.
Described sleeve pipe 3 uses plastics or elastomeric material to make.When using plastics or elastomeric material makes described sleeve pipe 3, it is possible to adopt the mode of injection moulding that sleeve pipe 3 is directly injected into described multidiameter 21 position, straight forming.
As shown in Figure 2, pad includes shim body 12, shim body 12 is in pentagon, this shim body 12 is provided with waist-shaped hole 22 and a hexagon ring 32, wherein, hexagon ring 32 is positioned at the centre position of shim body 12, being preferably shaped to circular arc and being arranged on the avris of shim body 12 of waist-shaped hole 22, so can be easy to the installation of pad and fixing.
As it is shown in figure 1, described screw head 1 adopts hexagon head structure；Described screw head 1 can also adopt interior hexagonal or other structure.
As it is shown in figure 1, adopt helicitic texture to be connected between described sleeve pipe 3 and multidiameter 21.Demountable structure is adopted, so when described sleeve pipe 3 damages, it is possible to adopt the mode of more casing replacing 3 to be repaired by whole bolt between described sleeve pipe 3 and multidiameter 21.It is also equipped with cushion 4 between described sleeve pipe 3 top and stud 2 stepped locations.Described cushion 4 can play the top pressure effect to sleeve pipe 3, and so when this bolt is twisted, described sleeve pipe 3 deformation quantity is bigger, screwed hole is produced bigger grasp so that the whole stress of bolt is more balanced.
As it is shown on figure 3, the end face of nut is provided with the rubbing surface 1-1 of the frictional force increased between contact surface (i.e. the contact surface of held workpiece), this rubbing surface is preferably ratchet 1-2 structure, and described ratchet is helical teeth, and ratchet is circumferentially in uniform setting.
Above-described is only embodiment of the present utility model, 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 premise without departing from this utility model structure, it is also possible to make some deformation and improvement; these also should be considered as protection domain of the present utility model, and these are all without affecting effect and the practical applicability that this utility model is implemented.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. records the content that may be used for explaining claim.
