Description
Technical field
This utility model is related to field of mechanical technique, particularly a kind of with the bolt for preventing reverse rotation function.
Background technology
Known, common bolt can meet use requirement substantially typically all without auto-lock function used in general occasion.
But used in the occasion that some vibrations are larger, due to due to vibration, bolt looseness can be caused.The wherein railway carriage casing of rolling stock
Vibrating state is chronically at locomotive, bolt falling used is relatively conventional；It is used on the bridge securing member of some steel constructions
Bolt be also one of the emphasis safeguarded；Bolt used many bolts in the longtime running of equipment also can in plant equipment
Occur loosening, Aero-Space bolt wherein used is rocked by liter space-time also occur loosening, wherein refrigerator, refrigerator-freezer, displaying
The regulating bolt of the product such as cabinet and wine cabinet, in transit product run into the situation such as jolt, shake, screw rod is unscrewed even
Come off from product, put product to user installation and bring inconvenience, can also give the goodwill band of production Li Kou works enterprise
Carry out adverse effect.Especially its each composition mechanism of current various plant equipment, the connection between part and plant equipment body
How with bolts variator is with being fastenedly connected for chassis etc., and various transmission pipelines are more by the connection of adpting flange
Connected using bolt, nut.Traditional bolt, nut connected mode is with shaking that logistics campaign in mechanical movement or pipeline causes
Action is used, and the work(silk of bolt meeting relative device body produces loosening, and the relative generation loosening of meeting, of long duration between nuts and bolt
Nut or bolt falling can be even caused, and then produces serious potential safety hazard.In order to prevent the fastening connection pieces such as bolt, nut
Loosening, people meet later the needs that various plant equipment are fastenedly connected using spring pad and various loosing-proof devices.But
Because above-mentioned measure yet suffers from actual use the defect of anti-impact force difference and anti-vibration scarce capacity, using bolt, spiral shell
The plant equipment that mother is fastenedly connected still is susceptible to connect the problem for loosening in running, so that connector loses them
The function of itself, causes device damage or is not normally functioning.
With the progress of social science and technology, industrial and agricultural production mechanization, automaticity are rapidly improved, the peace to plant equipment
Full property is put forward higher requirement.For the purpose of safety, attachment security, the reliability between plant equipment, parts is more required,
The loss that the security of the lives and property and country, the economy of collective otherwise to working people is caused will be huge, also be unfavorable for
Harmony, the stable development of society.Therefore, it is necessary to designing, a kind of connection is reliable, use the fixedly connected part of safety.
The content of the invention
Technical problem to be solved in the utility model be to provide it is a kind of with prevent reversely rotate function bolt, pass through
Locking member is set, for solving that existing bolt is susceptible to derotation under the conditions of the long-term vibration and the technology of loose or dislocation is asked
Topic.
In order to realize solving the purpose of above-mentioned technical problem, this utility model employs following technical scheme：
It is of the present utility model a kind of with preventing from reversely rotating the bolt of function, for preventing the spiral shell as fixedly connected part
Bolt reversely rotates loose or dislocation under the conditions of in long-term vibration, it is characterized in that：Including bolt and locking member；
The bolt includes screwing head, screw rod and nut；Screw rod is vertically set on and screws head lower section, and its side is provided with locking
Groove；
The nut side is provided with least one locking hole；Nut downside is provided with blind hole, and locking is provided with the blind hole
Pin；It is connected by flexible member between locking pin and nut, locking pin is stretched out or retraction blind hole；The locking pin lower end is
Hemispherical dome structure；When this is for the ease of using the shockproof self-locking screw, installation locking part；
Alignment mark is additionally provided with the nut；Make when this is for the ease of using on the locking hole and screw rod on nut
Locking slot is aligned；
The locking member is U-shaped part, and the upper end of the 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；
The nut sleeve on screw rod, insert in the locking hole of nut side, the tight lock part of U-shaped part by the pin interpolating unit of U-shaped part
In the locking slot of insertion screw rod side, the locking pin on nut is inserted in the through hole on U-shaped part locking area.
Specifically：It is described to screw head for outer six side, interior six side, outer cubic or interior tetragonal.
Specifically：The bolt also includes cushion, and the cushion is arranged on nut top.This is in order to be able to fine adjustment spiral shell
Mother's rotation, is easy to the locking hole on nut corresponding with the locking slot on screw rod.
Specifically：The nut top is provided with elastic layer.
Specifically：Described also to include mounting blocks with the bolt for preventing reverse rotation function, the mounting blocks are provided with swollen for one
The cylindrical section of swollen head, the length of the cylindrical section is equal to the thickness of locking area on U-shaped part.When nut is installed, nut is tightened in rotation
And make the locking hole on nut corresponding with the locking slot on screw rod；Then the mounting blocks are inserted into from below U-shaped part locking area
On through hole in, then the cylindrical section of mounting blocks just by U-shaped part locking area through hole block；Then by the pin interpolating unit of U-shaped part
In the locking hole of insertion nut side, in the locking slot of the tight lock part insertion screw rod side of U-shaped part；Then mounting blocks are extracted out, then
In the through hole that locking pin is fallen on U-shaped part locking area；Because the pin interpolating unit of U-shaped part is stuck on nut, tight lock part is stuck in screw rod side
In the locking slot in face, then nut can not occur to reversely rotate and loose or dislocation under long-term vibration environment, also from screw rod.
It is further specific：The material of the mounting blocks is rubber.Using the elasticity of quality of rubber materials, be conducive to mounting blocks with
The tight fit of U-shaped part, prevents it from sliding when mounted.
These technical schemes, including improved technical scheme and further improved technical scheme can also be combined with each other
Or combine, so as to reach superior technique effect.
There is following beneficial effect by adopting above-mentioned technical proposal, this utility model：
It is of the present utility model a kind of with preventing from reversely rotating the bolt of function, using the nut of locking pin, with U-shaped part
Through hole on locking area is engaged, and is prevented from nut and rotates loose or dislocation from screw rod under long-term vibration environment, effectively
Solve and solve the technical problem that existing bolt easily rotates loose or dislocation under the conditions of in long-term vibration, realize railcar
, the normal use or safe operation of automobile, bridge securing member, plant equipment, Aero-Space and household electrical appliances；Present configuration letter
Single, cost is relatively low, and safe effect is better than existing bolt, with certain market and application prospect.
