Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-6, a locking nut assembly with multiple fastening structures, including a screw rod 1, a spacing circular plate 6, a second thread 3 and a first thread 2 are sequentially arranged on the screw rod 1 from top to bottom along the axial direction thereof, the directions of the first thread 2 and the second thread 3 are opposite, a first nut 4 is screwed on the first thread 2, a first elastic gasket 15 is arranged at the bottom end of the first nut 4, the existence of the first elastic gasket 15 can increase the friction force of the contact surface between the first nut 4 and the component to be fixed, the locking performance is enhanced, the loss generated between the component to be fixed and the component to be fixed can be reduced, and the surface of the component is protected while the first nut 4 is protected.

A limiting circular plate 6 is sleeved on the first screw thread 2, the limiting circular plate 6 is positioned above the first nut 4, first threaded holes 9 are symmetrically formed in the left side and the right side of the limiting circular plate 6 along the circle center of the limiting circular plate 6, a plurality of limiting rods 7 are arranged on the inner wall of the limiting circular plate 6 in a surrounding mode, the extending direction of the plurality of limiting rods 7 is parallel to the axial direction of the screw 1, the number of the limiting rods 7 is at least 4, the force action between the limiting circular plate 6 and the first nut 4 can be generated by the combination of the limiting rod 7 and the limiting groove 8, when the first nut 4 tends to loosen, the limiting rod 7 can limit the first nut 4 by itself on one hand, and can limit the first nut 4 more powerfully by the connection between the limiting circular plate 6 and the second nut 5 where the limiting rod 7 is located on the other hand, so that the loosening of the first nut is prevented, and the larger the number of the limiting rods 7 is, the larger the limiting force on the first nut 4 is, the more stable the limiting rod is.

The inner wall of the first nut 4 is provided with a plurality of limiting grooves 8 corresponding to the limiting rods 7 in a surrounding manner, each limiting rod 7 is inserted in the corresponding limiting groove 8, two sides of the inner wall of each limiting groove 8 are vertically provided with clamping grooves 17, the left side and the right side of each limiting rod 7 are fixedly provided with clamping strips 18 matched with the clamping grooves 17, and the outer side of each limiting rod 7 is provided with an anti-skid rubber surface 14, can make gag lever post 7 inseparabler when combining with spacing groove 8 through the cooperation of gib 18 and draw-in groove 17, the gag lever post 7 is equipped with anti-skidding rubber face 14 outward, and the frictional force that has increased when gag lever post 7 and spacing groove 8 combine makes its combination inseparabler on the one hand, and frictional force when on the other hand can increase gag lever post 7 surface and first screw thread 2 contact can also reduce the wearing and tearing of gag lever post 7 to first screw thread 2 through anti-skidding rubber face 14, protects first screw thread 2.

The second screw thread 3 is in screwed connection with a second nut 5, the left side and the right side of the second nut 5 are fixedly provided with fixed blocks 10, each fixed block 10 is vertically provided with a second screw hole 11 corresponding to the first screw hole 9, each second screw hole 11 is internally in screwed connection with a screw fixing rod 12, the bottom end of each screw fixing rod 12 passes through the first screw hole 9 and the penetrating end thereof is in screwed connection with a fixed nut 13, the second nut 5 and the limiting circular plate 6 can be fixed by combining the pair of screw fixing rods 12 and the pair of fixed nuts 13, when the first nut 4 has a loosening trend, the limiting circular plate 6 is driven by the limiting rod 7 to move along the same trend with the first nut, the limiting circular plate 6 drives the connected second nut 5 to move along the same trend, but because the direction of the second screw thread 3 of the second nut 5 is opposite to the first screw thread 2, the direction of the same trend movement of the second nut 5 and the first nut 4 is a locking direction, can restrict the not hard up trend of first nut 4, reach locking effect, when second nut 5 had not hard up trend like this, can transmit trend for first nut 4 through spacing plectane 6, because the direction of the first screw thread 2 at first nut 4 place is opposite with second screw thread 3, so first nut 4 and second nut 5 are locking direction with trend direction of motion, can restrict the not hard up trend of second nut 5, restrict the restriction each other and reach locking effect.

The top end of each fixing nut 13 is provided with a second elastic gasket 16, and the second elastic gasket 16 is used for increasing the friction force of the contact surface of the fixing nut 13 and the limiting circular plate 6, and enhancing the looseness prevention of the fixing nut 13 so that the fixing is firmer.

The working principle is as follows: when the assembly is used, the first nut 4 is rotated clockwise along the first threads 2 to be in contact with the surface of a component to be fixed, after the assembly is screwed down, the plurality of limiting rods 7 at the bottom of the limiting circular plate 6 are inserted into the corresponding limiting grooves 8, after the assembly is completed, the second nut 5 is rotated anticlockwise along the second threads 3 until each second threaded hole 11 is aligned with the corresponding first threaded hole 9, each thread fixing rod 12 is inserted into the corresponding second threaded hole 11, after the bottom end of each thread fixing rod passes through the corresponding first threaded hole 9, each fixing nut 13 is rotated along the penetrating end of the corresponding thread fixing rod 12 to be fixed, and at the moment, the assembly of the whole assembly is completed; when the anti-loosening mechanism works, the first nut 4 has a loosening tendency, and can rotate and rise along the first thread 2 anticlockwise, the plurality of contact limiting rods 7 can be driven to move in the same tendency, and further the limiting circular plate 6 is driven to rotate and rise anticlockwise, the limiting circular plate 6 drives the second nut 5 to rotate anticlockwise through the pair of thread fixing rods 12, but because the direction of the second thread 3 of the second nut 5 is opposite to that of the first thread 2, the anticlockwise rotating direction of the second nut 5 is the locking descending direction, the anticlockwise rotating and rising of the limiting circular plate 6 are limited, so that the anticlockwise rotating and rising of the first nut 4 is limited, the purpose of limiting the loosening of the nut is achieved, otherwise, when the second nut 5 has a loosening tendency, the second nut 5 can be transmitted to the first nut 4 through the limiting circular plate 6, and because the directions of the threads are different, the first nut 4 can limit the loosening of the second nut 5, mutually restrict to achieve the anti-loosening purpose.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
