Abstract

The utility model discloses a clamping type locknut which comprises a nut body and a clamping thread. The nut main body is made of a flexible material and is provided with a through hole, clamping threads are arranged in the through hole, one end of the nut main body is conical, an opening is formed in the end opening, the opening penetrates through the wall of the whole nut hole and the rail, and the rail is arranged at the other end of the nut main body. One side or two sides of the tooth form angle of the clamping thread are provided with thickening layers, and the screw threads can be clamped after the diameter of the nut body is reduced by external force, so that the tightly-holding type locknut cannot be loosened.

Description

Clamping type locknut

Technical Field

The utility model relates to the technical field of fasteners, in particular to a locknut.

Background

The locking by using the screw is already the existing technology of many industries, and the existing screw usually has the problem of poor engagement between the external thread and the internal thread of the nut, which often causes the screw and the nut to loosen in a vibrating environment or after long-term use. In order to improve the problem, many previous proposals have been made to improve the screw structure, but the problem of loosening cannot be solved completely, and the structure is complex and the cost is high.

The utility model content is as follows:

the utility model aims to provide a nut which thoroughly solves the defect of poor anti-loosening effect of the existing nut.

The utility model discloses a clamping type locknut which comprises a nut body and a clamping thread.

The locknut main body of the utility model has the characteristics that: the nut main part is equipped with the through-hole, the through-hole is equipped with and presss from both sides tight screw thread, nut main part pore wall one end sets up to coniform to be equipped with a plurality of opening in pore wall port portion, one of them opening extends and link up whole nut main part pore wall and riser, and the other end is equipped with the riser. The locknut main body is made of materials with certain toughness, and is extruded from the outside to reduce the diameter.

The tightening screw thread is characterized in that a tooth form angle thickening layer is arranged on the thread inclined plane on one side or two sides of the tooth form angle of the clamping screw thread, so that the clearance between the clamping screw thread and the screw thread is reduced, and the clamping screw thread can clamp and lock the screw thread after the diameter of the locking nut body is reduced.

Reference numbers in the drawings: the nut comprises a nut body 1, an opening 2, a clamping thread 3, a thread angle thickening layer 4, a rail 5, a screw thread 6 and a clamping thread 7.

Detailed Description

The utility model will be further described with reference to the drawings and examples, but the utility model is not limited thereto. All simple equivalent changes and modifications made in accordance with the claims and the contents of the specification are within the scope of the claims.

The clamping type locknut comprises a nut body and a clamping thread. After the clamping type nut body is screwed into a required position of the screw, another device and the conical end of the locknut form a spiral type gradual diameter reducing process, the locknut gradually reduces the inner diameter under the action of external force, so that the clamping thread gradually clamps the screw thread until the locknut is completely locked, and the locknut cannot be loosened under any vibration.

Claims

1. The utility model provides a clamping-type locknut, includes nut main part (1), presss from both sides tight screw thread (3), its characterized in that: nut main part (1) is equipped with the through-hole, be equipped with in the through-hole and press from both sides tight screw thread, the characteristic of pressing from both sides tight screw thread (3) is provided with profile angle thickening layer (4) on the screw thread inclined flank of pressing from both sides tight screw thread (3) profile angle one side or both sides, receives outside extrusion to cooperate with the nut main part, to the screw in screw rod thread (6) of pressing from both sides tight screw thread (7) press from both sides tightly.

2. The clamping type locknut of claim 1 wherein, one end of the hole wall of the nut main body is arranged in a conical shape, a plurality of openings (2) are arranged at the end part of the conical hole wall, and the nut main body is arranged in a material with certain toughness and is provided with a rail (5).
