Detailed Description

Referring to fig. 1, the present application provides a technical solution: a replaceable anti-theft nut comprises a nut body 1.

Referring to fig. 1 and 2 and fig. 3, in the present embodiment: the vertical cross-section of nut body 1 is ring shape, and ring channel 2 has been seted up to the lateral wall of nut body 1, and the inner wall block of ring channel 2 is connected with sleeve 3 on nut body 1, and four lugs 4 of the inner wall fixedly connected with of ring channel 2 on nut body 1, lug 4 rotate can drive nut body 1 and rotate. The sleeve 3 is all seted up flutedly 5 for the position of four lugs 4, the size of recess 5 on the sleeve 3 and the size looks adaptation of lug 4, and sleeve 3 rotates and can drive lug 4 and rotate. One end fixedly connected with driving plate 6 that nut body 1 was kept away from to sleeve 3, and driving plate 6 rotates and can drive sleeve 3 and rotate. The vertical cross-section of driving plate 6 is regular hexagon, and round hole 7 has been seted up on the surface of driving plate 6, and round hole 7 is linked together with sleeve 3 on the driving plate 6, and round hole 7 reaches when twisting nut body 1, makes the bolt can pass the effect on driving plate 6 surface.

Referring to fig. 1 and 3 and fig. 4, concretely, two fixed plates 8 are fixedly connected with the arc surface of the sleeve 3, the fixed plates 8 rotate to drive the sleeve 3 to rotate, the vertical cross section of the fixed plates 8 is U-shaped, the inner wall of the fixed plates 8 rotates to be connected with a rotating rod 9, and when the rotating rod 9 is rotated, the rotating rod 9 drives the fixed plates 8 to rotate. The arc surface of the rotating rod 9 is sleeved with the anti-skidding sleeve 10, the anti-skidding sleeve 10 is a silica gel sleeve, and the anti-skidding sleeve 10 achieves the effect of increasing the friction force of the arc surface of the rotating rod 9. The arc surface of bull stick 9 slides and runs through has inserted bar 11, and inserted bar 11 and fixed plate 8 sliding connection, and fixed plate 8 is located between inserted bar 11 and antiskid cover 10, and when inserted bar 11 inserts the back in the bull stick 9, because fixed plate 8 is located between inserted bar 11 and antiskid cover 10, inserted bar 11 reaches the effect of preventing bull stick 9 rotation as far as possible this moment. One end fixedly connected with haulage rope 12 of inserted bar 11, haulage rope 12 keep away from the one end and the sleeve 3 fixed connection of inserted bar 11, and haulage rope 12 reaches when not using inserted bar 11, carries out the effect of restriction to the position of inserted bar 11.

Referring to fig. 2 and 3, specifically, one side of the driving plate 6 close to the nut body 1 is fixedly connected with two guide rods 13, the nut body 1 has been provided with guide grooves 14 for the positions of the two guide rods 13, the size of the guide grooves 14 on the nut body 1 is matched with the size of the guide rods 13, the driving plate 6 can drive the guide rods 13 to move when moving, when the guide rods 13 slide along the inner walls of the guide grooves 14, the guide grooves 14 reach the sliding paths of the guide rods 13 so as to limit the sliding paths of the driving plate 6, and further, the bumps 4 and the grooves 5 are aligned.

The theory of operation, when needs use nut body 1, remove driving plate 6 earlier, driving plate 6 can drive guide bar 13 during the removal and remove, when guide bar 13 slides along the inner wall of guide groove 14, thereby guide groove 14 reaches restriction guide bar 13 slip path and restricts driving plate 6 slip path, and then make the effect that lug 4 and recess 5 aligned, continue to slide driving plate 6 and can make sleeve 3 slide in along the inner wall of ring channel 2, sleeve 3 slides and can make lug 4 insert in recess 5, then rotate bull stick 9 along the inner wall of fixed plate 8, after bull stick 9 rotated suitable position, insert the arc surface at bull stick 9 with inserted bar 11, because fixed plate 8 is located between inserted bar 11 and antiskid cover 10, inserted bar 11 reaches the effect of preventing bull stick 9 rethread at this moment.

Then rotate two bull sticks 9, fixed plate 8 rotates with the help of bull stick 9 and can drive sleeve 3 and rotate, antiskid cover 10 reaches the effect of increase bull stick 9 surface friction power this moment, can drive lug 4 when sleeve 3 rotates and rotate, lug 4 rotates and can drive nut body 1 and rotate, bull stick 9 reaches the effect of the manual rotation nut body 1 of person of facilitating the use this moment, round hole 7 reaches when twisting nut body 1 this moment, make the bolt pass the effect on driving plate 6 surface, after nut body 1 moves suitable position, remove inserted bar 11 once more and make inserted bar 11 and bull stick 9 break away from the contact, haulage rope 12 reaches restriction inserted bar 11 position this moment, the effect that the person of facilitating the use used next time, driving plate 6 reaches the effect that the person of facilitating the use uses the spanner to further tighten nut body 1, nut body 1 of ring shape structure reaches and lets other personnel be difficult to rotate nut body 1 and make nut body 1 take place not hard up the effect.
