Technical field
The utility model belongs to wind turbine equipment and manufactures field, particularly a kind of wind-powered electricity generation self-locking screw.
Background technique
China is the country of a wind energy abundance, annual increasing wind power plant starts to come into operation, the vibration of fixing bolt generation when being subject to blade of wind-driven generator and rotating of existing wind-driven generator, bolt is easy to get loose, define serious potential safety hazard, affect the normal use of wind-driven generator.
Model utility content
For solving defect of the prior art, the utility model provides a kind of wind-powered electricity generation self-locking screw, this wind-powered electricity generation self-locking screw can will ensure the fastening dress state of bolt, prevent the vibration owing to producing when blade of wind-driven generator rotates from causing fixing bolt to occur the potential safety hazard got loose, effectively ensure that the normal use of wind-driven generator.
Technological scheme:
A kind of wind-powered electricity generation self-locking screw, comprises bolt body, locking card and threaded stem; Described bolt body is fixed on described threaded stem top; To having nose bar bottom described bolt body, described nose bar outer wall is provided with outside thread, is arranged with brute spring outside described nose bar; Described threaded stem top is outwards provided with annular boss, and described annular boss is inwardly provided with the interior threaded hole corresponding with described nose bar outside thread, is provided with bottom thread bottom described threaded stem, and the bottom of described interior threaded hole is to having interior hexagonal shrinkage pool; The bottom of described threaded stem is inwardly provided with locking draw-in groove, and the fixed end of described locking card is built in described locking draw-in groove; Described locking card stretches out described locking draw-in groove and along bending outside screw thread up time direction, the dogleg section surface of described locking card is provided with the breach corresponding with described bottom thread gap length.
Preferably, described bolt body is six column structures.
Preferably, described brute spring adopts chromium alloyed steel material.
Technique effect:
The utility model provides a kind of wind-powered electricity generation self-locking screw, and compared to the prior art, the utility model has following beneficial effect:
When wind-powered electricity generation self-locking screw is fastened on the threaded securing bores of wind-driven generator, stressed built-in locking card dogleg section and the screw thread of making of bolt threaded portions is fitted, when bolt is subject to the vibration owing to producing when blade of wind-driven generator rotates, the bending part branch of locking card is stuck in thread engagement place, goes into the effect of reverse locking.Be arranged with brute spring outside nose bar by the anti-loosening property of bolt body can be promoted with the active force of annular boss simultaneously.Brute spring adopts chromium alloyed steel material, and elasticity is good, and what effectively ensure that wind-powered electricity generation self-locking screw is fastened with validity.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of wind-powered electricity generation self-locking screw in the utility model;
In figure, each label example is as follows:
Hexagonal shrinkage pool, the locking card of 9-, the locking draw-in groove of 10-in 1-bolt body, 2-brute spring, 3-threaded stem, 4-annular boss, 5-bottom thread, 6-nose bar, 7-interior threaded hole, 8-.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Fig. 1 is the structural representation of a kind of wind-powered electricity generation self-locking screw in the utility model, and as shown in Figure 1, the utility model provides a kind of wind-powered electricity generation self-locking screw, comprises bolt body 1, threaded stem 3 and locking card 9; Bolt body 1 is fixed on threaded stem 3 top; To having nose bar 6 bottom bolt body 1, nose bar 6 outer wall is provided with outside thread, is arranged with brute spring 2 outside described nose bar 6, is now arranged with brute spring 2 outside nose bar 6 by promoting the anti-loosening property of bolt body 1 with the active force of annular boss 4.
Threaded stem 3 top is outwards provided with annular boss 4, and annular boss 4 is inwardly provided with the interior threaded hole 7 corresponding with nose bar 6 outside thread, makes bolt body 1 be fixed on threaded stem 3 top by thread engagement.Be provided with bottom thread 5 bottom threaded stem 3, the bottom of interior threaded hole 7 is to having interior hexagonal shrinkage pool 8.After bolt body 1 is disassembled, annular boss 4 and threaded stem 3 are also in fastened state, and must put in the interior hexagonal shrinkage pool 8 of rotation in interior threaded hole 7 by special tool could dismantle by double thread bar 3.The bottom of described threaded stem 3 is inwardly provided with locking draw-in groove 10, and one end of described locking card 9 is fixed end, is built in described locking draw-in groove 10; The other end of described locking card stretches out described locking draw-in groove 10 and along bending outside screw thread up time direction, the dogleg section surface of described locking card 9 is provided with the breach corresponding with described bottom thread 5 gap length.Further, bolt body 1 is six column structures.Conveniently dismantled by Wrench, structure is simple, convenient operation.Brute spring 2 adopts chromium alloyed steel material, and elasticity is good, and what effectively ensure that wind-powered electricity generation self-locking screw is fastened with validity.
When wind-powered electricity generation self-locking screw is fastened on the threaded securing bores of wind-driven generator, stressed built-in locking card 9 dogleg section and the screw thread of making of bolt threaded portions is fitted, when bolt is subject to the vibration owing to producing when blade of wind-driven generator rotates, the bending part branch of locking card 9 is stuck in thread engagement place, goes into the effect of reverse locking.Be arranged with brute spring 2 outside nose bar 6 by the anti-loosening property of bolt body 1 can be promoted with the active force of annular boss 4 simultaneously.
