Description
Technical field
The utility model relates to a kind of thread joined structure, especially a kind of screw disconnecting prevention structure for set screws.
Background technique
Along with increasing mechanical component is employed in industrial production and daily life, the reliability of mechanical component and Security also cause people to pay close attention to further.Various coupled type is had, as welding, scyewed joint and viscose glue connection etc. in the middle of mechanical structure.Because scyewed joint can obtain very high linking intensity, and be convenient to mounting or dismounting, have interchangeability, can produce in enormous quantities, the low and low price of cost, so scyewed joint is one of most important joining method.The technical requirements of screwed tight is higher, in assembly process, occur that bolt or screw do not reach the situation of screw-down torque requirement sometimes because of various reasons, the bolt do not tightened in mechanical part operation process or screw can loosen gradually and then deviate from, cause part to connect to lose efficacy, machinery assembly cannot normally work, the screw even deviate from can be thrown away by the parts at high speeds rotated and wound other parts or personnel, causes the loss of personal security and equipment.Some pad for nut anti-looseness at present, but rarely seen for screw anticreep, the particularly structure of set screws anticreep, for set screws coupling member, should consider and prevent deviating from of screw, take into account efficiency of assembling again.
Model utility content
The purpose of this utility model is the drawback for prior art, providing a kind of by changing gasket construction, avoiding screw to deviate from the screw disconnecting prevention structure for set screws of risk.
Problem described in the utility model is realized by following technical proposals:
A kind of screw disconnecting prevention structure for set screws, specialization is: it comprises positioning baseplate, described positioning baseplate is provided with one group of screw mounting hole, screw in screw in each screw mounting hole and lock, on positioning baseplate, each screw mounting hole side is provided with the anti-flake of elasticity, and the tail end of the anti-flake of each elasticity is positioned at each screw head.
The above-mentioned screw disconnecting prevention structure for set screws, the root of the anti-flake of described elasticity fixes through riveting or welding with positioning baseplate, the anti-flake of elasticity bends to the screw position place corresponding to it, and under the anti-flake nature of elasticity, its tail end mates to the distance of substrate and the height dimension of screw head.
The above-mentioned screw disconnecting prevention structure for set screws, the tail end of the anti-flake of described elasticity is provided with hook-shaped bending.
The above-mentioned screw disconnecting prevention structure for set screws, on described positioning baseplate, the number of one group of screw mounting hole is no less than two.
The utility model provides a kind of screw disconnecting prevention structure for set screws for solution set screws anticreep problem.Described structure comprises positioning baseplate, and screw connects fastener through positioning baseplate, and positioning baseplate arranges one group of anti-flake of elasticity, and the corresponding each screw head in each elasticity anti-flake end, suppresses deviating from of screw by the anti-flake of elasticity.The utility model utilizes the anti-drop function of resiliently deformable realization to screw of the anti-flake of elasticity, and this structure does not affect tightening of screw, can not increase installation time and operation easier.When adopting the utility model effectively can eliminate multiple screw-driving, respective bolts loosens, and reduces the risk that mechanical structure lost efficacy.The utility model can be used for the various mechanical structure needing set screws to connect.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram that the utility model first embodiment screw does not screw;
Fig. 3 is the utility model first embodiment screw tightening state schematic diagram;
Fig. 4 is the schematic diagram that the utility model second embodiment screw does not screw;
Fig. 5 is the utility model second embodiment screw tightening state schematic diagram.
In figure, each list of reference numerals is: 1, positioning baseplate, 2, the anti-flake of elasticity, 3, screw, 4, screw mounting hole, 5, fastened parts.
Embodiment
Referring to Fig. 1, the utility model comprises positioning baseplate 1, the shape of positioning baseplate and the shape of fastener similar, positioning baseplate is provided with one group of screw mounting hole 4, the position of each screw mounting hole is corresponding with the position of fastener upper bolt aperture, screws in screw 3 and lock in each screw mounting hole.Get loose for preventing screw, on positioning baseplate, each screw mounting hole side is provided with the anti-flake 2 of elasticity, the anti-flake of elasticity adopts the good tinsel of elasticity to make, the root of the anti-flake of elasticity fixes through riveting or welding with positioning baseplate, the anti-flake of each elasticity is respectively to the screw position place bending corresponding to it, the resiliently deformable of the anti-flake dependence of elasticity self, makes its tail end press at screw head, plays Anti-extrusion effect to screw.For making the anti-flake of elasticity press at screw head, under nature, the tail end of the anti-flake of elasticity mates to the distance of substrate and the height dimension of screw head.
Fig. 2, Fig. 3 are the states before first embodiment's screw-driving of the present utility model and after tightening.As seen from the figure, the screw mounting hole that screw 3 passes positioning baseplate 1 is screwed into the tapped hole of fastened parts 5, before screw-driving, the anti-flake 2 of elasticity is in below screw head, when tightening, bolt head moves down, in moving process, the inclined-plane of the anti-flake of bolt head compressing elasticity, makes its resiliently deformable that side direction occurs dodge bolt head and tightens.After screw-driving puts in place, the anti-flake of elasticity is in above bolt head, compresses the end face of bolt head, and when screw loosening, the anti-flake of elasticity can prop up bolt head and prevent it from deviating from.
Fig. 4, Fig. 5 are the states before second embodiment's screw-driving of the present utility model and after tightening.The tail end of the anti-flake of this embodiment's elasticity 2 is provided with hook-shaped bending 2-1, hook-shaped bending can make on the one hand the anti-flake of elasticity more stable press in screw head, elasticity anticreep sheet tail end can also be avoided on the other hand to scratch the hand of operator.
The utility model is applicable to set screws anticreep, and in set screws, the number of screw is no less than two (namely on positioning baseplate, the number of one group of screw mounting hole is no less than two).In fastener working procedure, when respective bolts gets loose, substrate is fixing by other screws, therefore can not the anti-drop function of the anti-flake of influence elastane.
