Abstract
The utility model relates to the fastening bolt component technical field of sleeper, especially relates to a kind of anti-loose anti-theft sleeper bolt assembly.Comprise bolt, lock washer and locknut, the locknut lower surface being characterized in described is provided with unidirectional ratchet, the corresponding unidirectional ratchet in lock washer upper surface is provided with non-return ratchet, bolt is vertically arranged with guiding stop mechanism, lock washer inner ring is provided with the card corresponding with the stop mechanism that leads to projecting inward.The setting of its bolt side guide stop mechanism and lock washer inner ring card, makes lock washer can vertically move along bolt and can not rotary motion; Being equipped with of unidirectional ratchet and non-return ratchet, make locknut unidirectional tightened-up operation only, and it is loosening to circle round; Whole fastener cycle, bolt restriction lock washer rotates, and the convolution of lock washer restriction bolt loosens, and bolt, once screw, just cannot loosen again and take off, thus achieve the effect of anti-loose anti-theft.
Description
Technical field
The utility model relates to the fastening bolt component technical field of sleeper, especially relates to a kind of anti-loose anti-theft sleeper bolt assembly.
Background technology
Existing railroad sleeper bolt, most employing plain bolt, when sharp pounding, due to repeat varying load or operating temperature higher time, normal pressure on nut rubbing surface there will be the phenomenon of momentary loss or reduction, vibration force along nut radial direction repeatedly repeats easily to impel nut rotation, causes nut loosening, causes safety of railway traffic hidden danger; In addition, existing bolt arrangement is easy to dismounting, is stolen sometimes, also can cause railway traffic safety hidden danger by lawless person.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art to provide a kind of anti-loose anti-theft sleeper bolt assembly, thus effectively solves the defect existed in prior art.
For achieving the above object, the technical scheme that the utility model is taked is: described anti-loose anti-theft sleeper bolt assembly, comprise bolt, lock washer and locknut, the locknut lower surface being characterized in described is provided with unidirectional ratchet, the corresponding unidirectional ratchet in lock washer upper surface is provided with non-return ratchet, bolt is vertically arranged with guiding stop mechanism, lock washer inner ring is provided with the card corresponding with the stop mechanism that leads to projecting inward.
Described guiding stop mechanism is that longitudinal locking groove or longitudinal circle lack face, and described card is the rectangular card of corresponding longitudinal locking groove or the corresponding longitudinally round cambered surface card lacking face.
Described unidirectional ratchet and non-return ratchet engagement are arranged, and unidirectional ratchet can only rotate clockwise, and rotate counterclockwise namely by the spacing clamping of non-return ratchet, cannot rotate counterclockwise.
The beneficial effects of the utility model are: described anti-loose anti-theft sleeper bolt assembly, the setting of its bolt side guide stop mechanism and lock washer inner ring card, lock washer can be vertically moved and can not rotary motion along bolt; Being equipped with of unidirectional ratchet and non-return ratchet, make locknut unidirectional tightened-up operation only, and it is loosening to circle round; Whole fastener cycle, bolt restriction lock washer rotates, and the convolution of lock washer restriction bolt loosens, and bolt, once screw, just cannot loosen again and take off, thus achieve the effect of anti-loose anti-theft.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model structural principle schematic diagram;
Fig. 2 is the structural representation that the utility model arranges locking groove;
Fig. 3 is that the utility model installs implementation result schematic diagram.
Shown in figure: 1. locknut, 2. lock washer, 3. bolt, 4. unidirectional ratchet, 5. non-return ratchet, 6. lead stop mechanism, 7. card.
Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figures 1 to 3, described anti-loose anti-theft sleeper bolt assembly, comprise bolt 3, lock washer 2 and locknut 1, locknut 1 lower surface being characterized in described is provided with unidirectional ratchet 4, the corresponding unidirectional ratchet 4 in lock washer 2 upper surface is provided with non-return ratchet 5, bolt 3 is vertically arranged with guiding stop mechanism 6, lock washer 2 inner ring is provided with the card 7 corresponding with the stop mechanism 6 that leads to projecting inward.
Further, described guiding stop mechanism 6 is that longitudinal locking groove or longitudinal circle lack face, and described card 7 is the rectangular card of corresponding longitudinal locking groove or the corresponding longitudinally round cambered surface card lacking face.
Further, described unidirectional ratchet 4 engages with non-return ratchet 5 and arranges, and unidirectional ratchet 4 can only rotate clockwise, and rotates counterclockwise namely by the spacing clamping of non-return ratchet 5, cannot rotate counterclockwise.
Described anti-loose anti-theft sleeper bolt assembly, when implementing to install, builds bolt lower end and is connected on sleeper, then lock washer 2 is set in bolt periphery, then screwed by locknut and be connected in above lock washer.The setting of bolt side guide stop mechanism and lock washer inner ring card, makes lock washer can vertically move along bolt and can not rotary motion; Being equipped with of unidirectional ratchet and non-return ratchet, make locknut unidirectional tightened-up operation only, and it is loosening to circle round; Whole fastener cycle, bolt restriction lock washer rotates, and the convolution of lock washer restriction bolt loosens, and bolt, once screw, just cannot loosen again and take off, thus achieve the effect of anti-loose anti-theft.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
