Abstract
The utility model relates to a bolt, in particular to a locking bolt of a motor vehicle. The locking bolt comprises a screw head, a side hole, a screw bolt, a fixing pin, a screw cap, a gasket and a spring, wherein the discoid screw head is positioned at the upper end of the cylindrical screw bolt and is integrated with the screw bolt; the side hole is a blind hole on the side wall of the screw bolt; the fixing pin is a round bar which is inserted into the side hole and in a clearance fit with the side hole, and an inclined surface facing down is arranged the outer end of the fixing pin; the spring is arranged in the side hole, one end of the spring is welded with the inner end of the fixing pin, and the other end of the spring is welded with the inner end wall of the side hole; and the lower extreme point of the inclined surface of the fixing pin is positioned in the side hole. In the utility model, the retractable fixing pin is arranged on the screw bolt, so as to eradicate the possibility that the bolt is loosened due to the vibrations of the motor vehicle, and improve the safety factor of the wheels of the motor vehicle during driving.
Description
Technical field
The utility model relates to a kind of bolt, particularly relates to the anti-loosening bolt of a kind of Motor Vehicle.
Background technique
In the process that automobile newly advances, because that continue, high-frequency vibration, the clamping bolt on the wheel is very easy to loosening, and this is the big potential safety hazard of one in the vehicle driving.
The model utility content
The utility model is for solving the deficiencies in the prior art, provide a kind of easy for installation, can stop bolt simultaneously the loosening anti-loosening bolt of Motor Vehicle takes place under vibration.
The scheme that solves the utility model technical problem is: the anti-loosening bolt of Motor Vehicle is made of screw head, side opening, screw rod, fixing pin, nut, packing ring and spring.Wherein, discoidal screw head is positioned at columniform screw rod upper end and as a whole with screw rod.Side opening is the blind hole that is positioned on the screw rod sidewall.Fixing pin is the round bar that inserts in the side opening and be in active relationship with side opening, and the outer end of fixing pin is an inclined-plane, and the inclined-plane down.Spring is located in the side opening, an end of spring and the inner of fixing pin welding, the other end of spring and the welding of the inner end wall of side opening.The lower extreme point on the inclined-plane of fixing pin is within the side opening; The upper extreme point on the inclined-plane of fixing pin is in outside the side opening.Nut be placed on the screw rod and with screw rod with screw-thread fit, between nut and screw head, also have a plurality of packing rings that are placed on the screw rod.
During operation, earlier screw rod is passed fastener and make fastener be affixed on the lower end of screw head, choose the packing ring of an amount of thickness and an amount of number again according to the thickness sum of nut and packing ring, make nut and a plurality of gasket thickness sum equal the summit of side opening and the distance between the screw head lower surface.Earlier packing ring is placed on the screw rod then, from the screw rod bottom nut is threaded onto on the screw rod again, when nut process side opening, because the outer end of fixing pin is downward inclined-plane, under the extruding of nut, in the fixing pin withdrawal side opening to fixing pin.Leave moment of side opening when the lower end of nut, stretch out from side opening again the outer end of fixing pin under the promotion of spring, because stopping of fixing pin arranged, the position of nut is locked.
Adopt such scheme, can reach following effect:
Because the utility model is provided with telescopic fixing pin on screw rod, and fixing pin has the function with the nut monodirectional locking, because of vibration causes bolt loosening possibility taking place with regard to having eradicated Motor Vehicle, has improved the safety coefficient in the vehicle wheels running process like this.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. screw head 2. side openings 3. screw rods 4. fixing pins 5. nuts 6. packing rings 7. springs 8. fasteners
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
The anti-loosening bolt of Motor Vehicle is made of screw head 1, side opening 2, screw rod 3, fixing pin 4, nut 5, packing ring 6 and spring 7.Wherein, discoidal screw head 1 is positioned at columniform screw rod 3 upper ends and as a whole with screw rod 3.Side opening 2 is the blind holes that are positioned on screw rod 3 sidewalls.Fixing pin 4 is the round bars that insert in the side opening 2 and be in active relationship with side opening 2, and the outer end of fixing pin 4 is an inclined-plane, and the inclined-plane down.Spring 7 is located in the side opening 2, an end of spring 7 and the inner of fixing pin 4 welding, the inner end wall welding of the other end of spring 7 and side opening 2.The lower extreme point on the inclined-plane of fixing pin 4 is within the side opening 2; The upper extreme point on the inclined-plane of fixing pin 4 is in outside the side opening 2.Nut 5 be placed on the screw rod 3 and with screw rod 3 with screw-thread fit, between nut 5 and screw head 1, also have a plurality of packing rings 6 that are placed on the screw rod 3.
During operation, earlier screw rod 3 is passed fastener 8 and makes fastener 8 be affixed on the lower end of screw head 1, choose the packing ring 6 of an amount of thickness and an amount of number again according to the thickness sum of nut 5 and packing ring 6, make nut 5 and a plurality of packing ring 6 thickness sums equal the summit of side opening 2 and the distance between screw head 1 lower surface.Earlier packing ring 6 is placed on the screw rod 3 then, from screw rod 3 bottoms nut 5 is threaded onto on the screw rod 3 again, when nut 5 process side openings 2, because the outer end of fixing pin 4 is downward inclined-planes, under the extruding of 5 pairs of fixing pins 4 of nut, in the fixing pin 4 withdrawal side openings 2.Leave moment of side opening 2 when the lower end of nut 5, stretch out from side opening 2 again the outer end of fixing pin 4 under the promotion of spring 7, because stopping of fixing pin 4 arranged, the position of nut 5 is locked.
