Problems solved by technology

When the hexagonal nut is connected with the bolt, there is a gap in the thread pair, so when it is used in a vibration place such as a railway, a pulverizer, a vibrator, an engine, etc., the fastening effect of the ordinary nut will often be weakened, resulting in the loosening of the ordinary nut. Even the threaded connection fails, which brings safety hazards and eventually leads to accidents
In the prior art, the anti-loosening method of connecting nuts and bolts usually adopts the method of increasing the pre-tightening force, such as adding elastic washers, nylon, etc., because it is affected by the impact force, vibration strength, temperature changes, etc., the pre-tightening force Difficult to stabilize, after a long time, the phenomenon of loosening is still serious

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] according to figure 1 As shown, the anti-loosening and anti-loosening hexagonal nut includes a hexagonal nut body 1 and a screw hole 3. The hexagonal nut body 1 is provided with a transverse wedge-shaped slot 2, and the depth of the wedge-shaped slot 2 reaches the depth of the screw hole 3. Center line; the angle of the wedge-shaped slot 2 is 3°.

[0014] In this embodiment, since the hexagonal nut body 1 is provided with a transverse wedge-shaped slot 2, the depth of the wedge-shaped slot reaches the center line of the screw hole 3. When the present invention is tightened with the bolt, the external force is used to hit this The position above the wedge-shaped slot 2 of the invention makes the gap of the wedge-shaped slot 2 smaller, and the local pitch of the nut changes, eliminating the gap between the thread pair of the present inven...

Abstract

The invention discloses a locking releasing-preventive hexagon nut which comprises a hexagon nut body and a screw hole. A transverse wedge-shaped slot is arranged on the hexagon nut body, and the depth of the wedge-shaped slot is proper so that the wedge-shaped slot reaches the center line of the screw hole. The locking releasing-preventive hexagon nut has the advantages of simple structure, convenience in installation, high safety performance and high practicality.

Description

technical field [0001] The invention relates to the technical field of fasteners, in particular to an anti-loosening anti-loosening hexagonal nut. Background technique [0002] Ordinary hexagon nuts are common fasteners, with internal threads in their screw holes and used in conjunction with bolts, and are widely used in the field of mechanical connections. When the hexagonal nut is connected with the bolt, there is a gap in the thread pair, so when it is used in a vibration place such as a railway, a pulverizer, a vibrator, an engine, etc., the fastening effect of the ordinary nut will often be weakened, resulting in the loosening of the ordinary nut. Even the threaded connection fails, which brings potential safety hazards and eventually leads to accidents. In the prior art, the anti-loosening method of connecting nuts and bolts usually adopts the method of increasing the pre-tightening force, such as adding elastic washers, nylon, etc., because it is affected by the impa...
