Embodiment Construction

[0022] The present invention will be described in detail below with reference to the accompanying drawings and the embodiments thereof, but the protection scope of the present invention is not limited to the scope described in the embodiments.

[0023] see Figure 1-6 , The nut structure in this embodiment includes three parts: a nut, a screw rod and a small screw.

[0024] Structure and composition

[0025] 1.1 Nut

[0026] figure 1 It is a schematic diagram of the nut structure of the present invention, and a certain number of evenly distributed through holes are drilled at corresponding positions on the nut. The left side of the figure is the front view of the nut, and the right side is the left side view. As can be seen from the front view in the figure, the center of the nut has a threaded hole, and there is an internal thread 2 in the threaded hole. The outside of the threaded hole of the nut has an annular nut body, and several through holes 1 are distributed along...

Abstract

The invention discloses a novel mechanical locking nut connection locking structure. The mechanical locking nut connection locking structure comprises a nut, a screw rod and a small screw. A thread hole is formed in the center of the nut; an internal thread is arranged in the thread hole; an annular nut body is arranged on the outer side of the thread hole of the nut; multiple through holes are annularly distributed on the nut body; the screw rod is provided with a screw rod body and a screw rod cap; and the screw rod body is columnar, and is provided with an external thread on the outer side.Multiple axial polish holes are formed in the nut; a small thread hole is formed in the shaft shoulder end surface of the screw rod; and the small screw with a spring is provided. When the locking isneeded after tightening of the nut, a front fine cylinder (smaller than the diameters of the polish holes of the nut) of the small screw is screwed out from the polish holes of the nut to prevent thenut from rotating relative to the screw rod so as to achieve the locking effect.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a mechanically locked nut anti-loosening structure used in a mechanical structure, especially in a vibration environment. Background technique [0002] The existing anti-loosening methods mainly include: mechanical locking type anti-loosening (reliable anti-loosening, can be repeatedly disassembled), free rotation type anti-loosening (unreliable anti-loosening, can be repeatedly disassembled), bonded anti-loosening (anti-loosening Slightly reliable, can be repeatedly disassembled), punch point riveting type anti-loosening (reliable anti-loosening, can not be repeatedly disassembled) and effective torque type anti-loosening (unreliable anti-loosening, can be repeatedly disassembled). [0003] Among them, the anti-loosening structure of the mechanical locking nut is reliable in anti-loosening, and can be disassembled repeatedly, so it is widely used. The existing mechanical lock nut anti-lo...
