Abstract
The utility model belongs to the technical field of fastening pieces and particularly relates to an anti-loosening and anti-dropping nut. The anti-loosening and anti-dropping nut comprises a nut body and spiral internal threads and is characterized in that a wedge-shaped inclined surface is arranged on the tooth bottom surface of the spiral internal threads, and a downward deformation indentation is arranged on a buckle half tooth on the uppermost layer of the internal threads. Compared with the prior art, the anti-loosening and anti-dropping nut has the advantages of simple structure, the wedge-shaped inclined surface is arranged on the tooth bottom surface of the spiral internal threads, and the tooth tip of external threads is propped against the wedge-shaped inclined surface of the internal threads during the use, therefore, an extremely big anti-loosening friction force is generated, and the purpose of locking is achieved; and in addition, the indentation is arranged on the non-supporting surface of the nut, the tooth shape of the indentation part is changed, the shape of the buckle half thread at the non-supporting surface end is changed, and when the external threads are screwed in, an interference fit is formed, and the purposes of self-locking and dropping prevention are achieved.
Description
[technical field]
The utility model relates to technical field of fastening, is a kind of locking screwed retaining ring specifically.
[background technique]
Along with expanding economy, the yard craft car industry is more and more important in carrier, owing to be easy to generate strenuous vibration in transit, get loose because of vibrations thereby make fastening piece, therefore be necessary to design a kind of anti-loose fastening piece to be used on the Transport Machinery.
[summary of the invention]
The purpose of this utility model is to overcome the deficiencies in the prior art, establishes the wedge shape inclined-plane in the position, tooth bottom of spiral internal thread, and adopts and establish impression on the non-supporting surface of nut, changes the screw thread form of non-supporting surface end place one button, half tooth.
For achieving the above object, design a kind of locking screwed retaining ring, comprise nut body, spirality internal thread, it is characterized in that: the tooth bottom surface of spirality internal thread is provided with the wedge shape inclined-plane, and a button half tooth of the internal thread the superiors is provided with the impression of downward distortion.
The utility model is compared with prior art, and is simple in structure, establishes the wedge shape inclined-plane in the position, tooth bottom of spirality internal thread, and externally threaded cusp presses closer on the wedge shape inclined-plane of internal thread during use, thereby produces great locking frictional force, has reached locking purpose; On the non-supporting surface of nut, establish impression in addition, impression part tooth form is changed, change a button partial thread shape of non-supporting surface end, when outside thread is screwed into, produce interference fit, reach the purpose of self-locking anticreep.
[description of drawings]
Fig. 1 is the utility model structural representation in an embodiment.
Referring to Fig. 1,1 is impression; 2 is the wedge shape inclined-plane; 3 is outside thread; 4 is nut body.
[embodiment]
Below in conjunction with accompanying drawing the utility model is further described.
Referring to Fig. 1, the tooth bottom surface of the internal thread of nut body 4 has wedge shape inclined-plane 2, angle between tooth bottom surface and the wedge shape inclined-plane 2 is about 150 °, the non-supporting surface of while nut body 4, promptly be provided with the impression 1 of downward distortion at a button half tooth of the spirality internal thread the topmost part of nut body 4, impression 1 can be made as three, promptly uniform along the circumference three equal parts of internal thread, because position, the tooth of internal thread bottom is provided with wedge shape inclined-plane 2, the cusp of outside thread 3 presses closer on the wedge shape inclined-plane 2 of internal thread during use, thereby produce great locking frictional force, reached locking purpose, simultaneously because the tooth form that impression 1 part causes variation, when being screwed into, outside thread 3 produces interference fit, reach the purpose of self-locking anticreep, without any need for auxiliary locking element, internal thread can mate with standard external during use.
Claims (1)
1. a locking screwed retaining ring comprises nut body, spirality internal thread, it is characterized in that: the tooth bottom surface of spirality internal thread is provided with wedge shape inclined-plane (2), and internal thread the topmost part one button half tooth is provided with the impression (1) of downward distortion.
