The bolt that a kind of anti-derotation comes off
Technical field
The present invention relates to field of mechanical technique, the bolt that a kind of anti-derotation comes off.
Background technology
Known, common bolt does not the most all have auto-lock function, is used in general occasion and substantially can meet use requirement.
But it is used in the occasion that some vibrations are bigger, due to vibration, bolt looseness can be caused.The wherein railway carriage casing of rolling stock
Being chronically at vibrating state with locomotive, bolt falling used is relatively conventional;Used by the bridge securing member of some steel constructions
Bolt be also one of the emphasis safeguarded;Bolt a lot of bolts in the longtime running of equipment used in plant equipment also can
Occur loosening, rocked when Aero-Space wherein bolt used is by going up to the air also there will be loosening, wherein refrigerator, refrigerator-freezer, displaying
The regulation bolt of the product such as cabinet and wine cabinet, in transit product run into jolt, the situation such as vibrations, usually make screw rod unscrew even
Come off from product, put product to user installation and bring inconvenience, also can give the goodwill band of production Li Kou work enterprise
Carry out adverse effect.The most current various plant equipment its respectively form the connection between mechanism, parts and plant equipment body
How with bolts such as variator is with being fastenedly connected of chassis etc., and various transmission pipeline is many by the connection of adpting flange
Bolt, nut is used to connect.Traditional bolt, nut connected mode are along with shaking that logistics campaign in mechanical movement or pipeline causes
Action use, the merit silk of bolt meeting relative device body produces and loosens, and can relatively produce loosening between nuts and bolt, of long duration
Even can cause nut or bolt falling, and then produce serious potential safety hazard.In order to prevent the fastening connection piece such as bolt, nut
Loosen, people used spring pad and various loosing-proof device to meet the needs that various plant equipment is fastenedly connected later.But
Owing to above-mentioned measure yet suffers from anti-impact force difference and the defect of anti-vibration scarce capacity in actual use, use bolt, spiral shell
The plant equipment that mother is fastenedly connected still is susceptible to connect the problem loosened, so that connector loses them in running
The function of self, causes device damage or is not normally functioning.
Along with the progress of society's science and technology, industrial and agricultural production mechanization, automaticity rapidly improve, the peace to plant equipment
Full property is had higher requirement.For the purpose of safety, more require the attachment security between plant equipment, parts, reliable,
The loss otherwise caused the security of the lives and property of working people and the economy of country, collective, by being huge, is also unfavorable for
The harmony of society, stable development.Therefore, it is necessary to design a kind of fixing connector connecting reliably, using safety.
Summary of the invention
The technical problem to be solved is to provide the bolt that a kind of anti-derotation comes off, and by arranging locking member, uses
In solving to be susceptible under the conditions of existing bolt is in long-term vibration the technical problem of derotation and loose or dislocation.
In order to realize solving the purpose of above-mentioned technical problem, present invention employs following technical scheme:
The bolt that a kind of anti-derotation of the present invention comes off, for preventing the bolt as fixing connector being in long-term vibration bar
Reversely rotate loose or dislocation under part, it is characterized in that: include bolt and locking member;
Described bolt includes screwing head, screw rod and nut;Screw rod is vertically set on and screws below head, and its side is provided with locking slot;
Described nut side is provided with at least one locking hole;Nut downside is provided with blind hole, is provided with locking pin in this blind hole;Lock
Tight pin is connected by flexible member with between nut, enables locking pin to stretch out or retraction blind hole;
Described locking member is U-shaped part, and the upper end of this U-shaped part is pin interpolating unit, and lower end is tight lock part, and tight lock part rear end is locking area,
Locking area is provided with the through hole corresponding with locking pin;
Described nut sleeve is on screw rod, and the pin interpolating unit of U-shaped part is inserted in the locking hole of nut side, and the tight lock part of U-shaped part inserts
In the locking slot of screw rod side, the locking pin on nut inserts in the through hole on U-shaped part locking area.
Concrete: described in screw head be outer six sides, interior six sides, outer four directions or interior tetragonal.
Concrete: described nut is provided with alignment mark.This makes the locking hole on nut and spiral shell when being for the ease of using
Locking slot alignment on bar.
Concrete: described locking pin lower end is hemispherical dome structure.When this is for the ease of using this shockproof self-locking screw, peace
Dress locking member.
Concrete: described bolt also includes cushion, and this cushion is arranged on above nut.This is to enable fine adjustment spiral shell
Female rotation, it is simple to the locking hole on nut is corresponding with the locking slot on screw rod.
Concrete: described nut is arranged over elastic layer.
Concrete: the bolt that described anti-derotation comes off also includes mounting blocks, and this mounting blocks is a cylinder being provided with expansion-head
Section, the length of this cylindrical section is equal to the thickness of locking area on U-shaped part.When installing nut, rotate fastening nut and make on nut
Locking hole corresponding with the locking slot on screw rod;Then this mounting blocks is inserted from below in the through hole on U-shaped part locking area,
Then the through hole on U-shaped part locking area is just blocked by the cylindrical section of mounting blocks;Then the pin interpolating unit of U-shaped part is inserted nut side
Locking hole in, the tight lock part of U-shaped part inserts in the locking slot of screw rod side;Then extract mounting blocks out, then locking pin falls into U-shaped
In through hole on part locking area;Owing to the pin interpolating unit of U-shaped part is stuck on nut, tight lock part is stuck in the locking slot of screw rod side,
Then nut is under long-term vibration environment, also can not occur to reversely rotate and loose or dislocation from screw rod.
The most concrete: the material of described mounting blocks is rubber.Utilize the elasticity of quality of rubber materials, beneficially mounting blocks with
The tight fit of U-shaped part, prevents its landing when mounted.
These technical schemes, the technical scheme including the technical scheme improved and improvement further can also be combined with each other
Or in conjunction with, thus reach superior technique effect.
By using technique scheme, the present invention has a following beneficial effect:
The bolt that a kind of anti-derotation of the present invention comes off, utilizes the nut of locking pin, matches with the through hole on U-shaped part locking area
Close, it is possible to prevent nut from rotating loose or dislocation under long-term vibration environment from screw rod, effectively solve the existing bolt of solution
The technical problem of loose or dislocation is easily rotated, it is achieved that rolling stock, automobile, bridge fasten under the conditions of being in long-term vibration
The normal of part, plant equipment, Aero-Space and household electrical appliances uses or safe operation;Present configuration is simple, and cost is relatively low, safety effect
Fruit is better than existing bolt, has certain market and application prospect.
