Detailed Description
Embodiments of the present utility model will be further described with reference to fig. 1 to 3.
The novel fastener comprises a bolt 1, a nut 2, a baffle 3, a connecting plate 4 and a clamping block 7;
The bolt 1 comprises a screw rod 101 and a nut 102, the screw rod 101 is fixedly connected with the nut 102, the baffle 3 is sleeved on the screw rod 101, the nut 2 is in threaded connection with the screw rod 101, and the baffle 3 is arranged between the nut 2 and the nut 102;
The two ends of the baffle 3 are respectively hinged with a connecting plate 4 for fixing the nut 2; corresponding clamping blocks 7 are respectively arranged on the two connecting plates 4, and anti-skid patterns for increasing the friction force between the baffle 3 and the nut 2 are arranged on one side of the baffle 3 contacted with the nut 2;
The nut 2 is in contact with the anti-skid patterns of the baffle 3 by abutting the nut 2 against the baffle 3 after the nut 2 is in threaded connection with the screw 101, so that friction force between the baffle 3 and the nut 2 is increased, and further, the nut 2 is prevented from rotating on the baffle 3.
Two sides of the nut 2 are respectively provided with a limit groove 5 for clamping the connecting plates 4, the two connecting plates 4 respectively extend into the corresponding limit grooves 5, the two connecting plates 4 are embedded with a first magnet 10, and the corresponding limit grooves 5 are embedded with a second magnet 11 for absorbing the first magnet 10;
Through rotating two connecting plates 4, rotate two connecting plates 4 and adsorb each other with second magnet 11 behind the corresponding spacing groove 5, and then fix two connecting plates 4 respectively in corresponding spacing groove 5, stretch into spacing hole 6 internal fixation with fixture block 7 on two connecting plates 4 again, and then fix nut 2 on screw rod 101.
The screw 101 is provided with a limiting hole 6 for fixing the clamping block 7, and a plurality of two sides of the screw 101 which are sequentially arranged are arranged in the limiting hole 6; an annular groove 8 is formed in the inner wall of the limiting hole 6, an annular protrusion 9 is arranged on the clamping block 7, the clamping block 7 stretches into the limiting hole 6, and the annular protrusion 9 is clamped with the annular groove 8;
The clamping block 7 stretches into the corresponding limiting hole 6, so that the annular bulge 9 on the clamping block 7 is arranged in the annular groove 8, the clamping block 7 is fixed in the limiting hole 6, and the connecting plate 4 is prevented from being separated from the limiting hole 6 due to long-time vibration of a machine, so that the connecting plate 4 is driven to be separated from the nut 2, and the effect of fixing the nut 2 cannot be achieved.
Working principle: when the nut 102 is used, the screw 101 passes through a workpiece through the tool piece, the baffle 3 is sleeved on the screw 101, one end of the baffle 3 is in contact with the workpiece, the nut 2 is in threaded connection with the screw 101, after the nut 2 is abutted against one end of the baffle 3 with anti-skid patterns, the connecting plates 4 at two ends of the baffle 3 are rotated to enable the connecting plates 4 to be rotated into the limit grooves 5 of the nut 2, the first magnet 10 and the second magnet 11 are enabled to be mutually adsorbed, the two connecting plates 4 are fixedly connected with the corresponding limit grooves 5, meanwhile, the clamping blocks 7 on the two connecting plates 4 extend into the corresponding limit holes 6, the annular protrusions 9 on the clamping blocks 7 are clamped with the annular grooves 8 in the limit holes 6, and then the clamping blocks 7 are fixed in the limit holes 6, so that the nut 2 cannot be rotated due to the limitation of the two connecting plates 4, and the fact that the nut 2 is loose is avoided.
