Embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
It should be noted that: any technical characteristics in the present embodiment, any technological scheme is all one or more in the technical characteristics of plurality of optional or optional technological scheme, cannot exhaustive all alternative technical characteristicss of the present utility model and alternative technological scheme in order to describe succinct to need in presents, also the mode of execution being not easy to each technical characteristics all emphasizes that it is one of optional numerous embodiments, so those skilled in the art should know: any technical characteristics in the present embodiment and any technological scheme all do not limit protection domain of the present utility model, protection domain of the present utility model should comprise those skilled in the art and not pay the thinkable any alternate embodiments of creative work.
Hereafter convenient in order to describe, hereinafter alleged "left", "right", " on ", left and right, the upper and lower of D score and accompanying drawing itself is to consistent.
As shown in Figure 1, 2, 3, the utility model provides a kind of device 1 being used to indicate nut loosening, can comprise fixing part 2 and instruction unit 3, and fixing part 2 is for being fixedly connected with nut, and instruction unit 3 is used to indicate the loosening situation of nut.
This principle being used to indicate the device of nut loosening installs an indicating device on nut, and the instruction unit of adjacent indicating device is relative between two when mounted.When nut get loose phenomenon and occur rotate time, because indicating device is fixed on nut, so nut can drive indicating device to rotate equal angular together, now the instruction unit of two adjacent indicating devices is no longer alignd but the angle that staggers, and can clearly indicate nut to get loose phenomenon.This kind of structure can make driver stop at any time to carry out visualize nut to get loose situation judge and work out measures.
This indicating device can make driver clearly make preliminary judgement when parking checking, whether a certain rim nut there is the phenomenon that gets loose, and the work using proprietary instrument to investigate one by one can be removed from, and this kind of indicating device can tentatively be investigated whenever and wherever possible, accomplish to put prevention first, and process in time when going wrong.
In a specific embodiment of the present utility model, fixing part 2 can be fixed hole, and fixed hole is set in the outside of nut and is fixedly connected with nut.
In a specific embodiment of the present utility model, the inwall of fixed hole can be provided with the saw shape tooth 5 with nut screw connection.
In a specific embodiment of the present utility model, saw shape tooth 5 can be uniformly distributed on the inwall of fixed hole.
In a specific embodiment of the present utility model, saw shape tooth 5 can be arranged on the top of fixed hole.
The top of fixed hole is saw shape toothing, and saw shape tooth is distributed in the fixed hole that regular hexagon outer with nut mate, and saw shape tooth angle degree, number and nut regular hexagon outer surface Matching installation, the bottom of fixed hole is match with nut non-slip mat structure to design.
The cross section of fixed hole can be circular.
In a specific embodiment of the present utility model, the angle of inclination of the flank of tooth of saw shape tooth 5 can be 10-60 degree.
In a specific embodiment of the present utility model, the angle of inclination of the flank of tooth of saw shape tooth 5 can be 45 degree.
In a specific embodiment of the present utility model, instruction unit 3 can be pointer, and the shape of pointer can be triangle.
Leg-of-mutton first end be there is the triangle edges of one fixed width, the second end is wedge angle, the triangle edges with one fixed width is connected with fixing part.The wedge angle of adjacent indicating device aligns between two when mounted, this kind of mounting type can by fixed hole top be saw shape tooth, the saw shape toothing be distributed in the fixed hole that mates with rim nut regular hexagon realizes, when occurring that indicating device does not realize wedge angle alignment between two, the fixed hole of suitably adjustment indicating device is only needed to mate angle with orthohexagonal outside rim nut.When nut get loose phenomenon and occur rotate time, because indicating device assembles by regular hexagon outside saw shape tooth and rim nut is fixing, so nut can drive indicating device to rotate equal angular together, now the wedge angle of two adjacent indicating devices no longer aligns but the angle that staggers, can judge that wherein a certain indicating device rotates, now can clearly indicate nut to get loose phenomenon.
As shown in Figure 4, the utility model additionally provides a kind of hoist, hoist comprises rim nut 4 and the device 1 being used to indicate nut loosening as above, and the fixing part 2 of device 1 is fixedly connected with rim nut 4, and the instruction unit 3 of the device 1 on rim nut 4 adjacent is between two alignd.
The indicating device of mounting strap arrow on the rim nut of full Terrain Cranes chassis wheel, driver can be stopped the situation that gets loose of visual inspection rim nut at any time, thus remind driver to carry out pretension the need of to a certain or some rim nut, prevent rim nut from getting loose and nothing is discovered, avoid occurring dangerous situation, this indicating device can improve face shaping simultaneously, improve the aesthetic property of wheel, increase the aesthetic property of car load, the contact avoided between rim nut and wheel set is directly exposed in air ambient, has preliminary anti-corrosion effect.
The other parts of hoist can, with reference to prior art, no longer be launched to describe herein.
Above-mentioned arbitrary technological scheme disclosed in the utility model unless otherwise stated, if the number range of it discloses, so disclosed number range is preferred number range, anyly it should be appreciated by those skilled in the art: preferred number range is only the numerical value that in many enforceable numerical value, technique effect is obvious or representative.Because numerical value is more, cannot be exhaustive, so the utility model just discloses component values to illustrate the technical solution of the utility model, and the above-mentioned numerical value enumerated should not form restriction the utility model being created to protection domain.
If employ the word such as " first ", " second " herein to limit component, those skilled in the art should know: the use of " first ", " second " is only used to be convenient to describe carry out difference as not having outside Stated otherwise to component, the implication that above-mentioned word is not special.
Simultaneously, if above-mentioned the utility model discloses or relate to component or the structural member of connection fastened to each other, so, unless otherwise stated, be fixedly connected with and can be understood as: can releasably be fixedly connected with (such as using bolt or screw to connect), also can be understood as: to be non-removablely fixedly connected with (such as rivet, weld), certainly, connection fastened to each other also can be replaced by integral type structure (such as use casting technique is integrally formed create) (obviously cannot adopt except integrally formed technique).
In addition, apply in arbitrary technological scheme disclosed in above-mentioned the utility model for represent position relationship or shape term unless otherwise stated its implication comprise approximate with it, similar or close state or shape.Arbitrary parts that the utility model provides both can be assembled by multiple independent constituent element, and also can be one of the forming manufacture technics separate part out.
