Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose of the present invention, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.

The utility model provides a locknut and have its vehicle, this locknut can take place to guarantee still after deformation and closely laminate by the installation face, prevents not hard up abnormal sound scheduling problem to appear.

Fig. 1 is the structural schematic diagram of locknut's orthographic view that the embodiment of the utility model provides, fig. 2 is the structural schematic diagram of looking down that locknut is shown, fig. 3 is the structural schematic diagram when locknut and installed surface laminating, fig. 4 is the structural schematic diagram of shell fragment when being installed the face and taking place deformation in the locknut that is shown. As shown in fig. 1 to 4, the locknut of the present invention includes a nut body 10, an elastic piece 20 is formed on an end surface of one end of the nut body 10 facing to a mounted surface 30, and when the nut body 10 is mounted on the mounted surface 30, the elastic piece 20 is disposed between the nut body 10 and the mounted surface 30 and is compressed.

In the present embodiment, by forming the elastic piece 20 on the end surface of the nut body 10 facing the end of the mounted surface 30, the elastic piece 20 is compressed when the nut body 10 is mounted on the mounted surface 30; as shown in fig. 4, once the mounted surface 30 deforms and a gap is formed between the mounted surface 30 and the nut body 10, the pressure applied to the elastic piece 20 is reduced, the elastic piece 20 continues to be pressed on the deformed mounted surface 30 due to the restoring force generated by the elastic piece 20, and as long as the gap between the mounted surface 30 and the nut body 10 is not larger than the size of the deformation of the elastic piece 20, the nut body 10 and the mounted surface 30 are always in the fit state, the torque of the locknut is not seriously attenuated, and looseness and abnormal sound are prevented from being generated.

Referring to fig. 1 and 2, in the present embodiment, a reinforcing surface 11 is further disposed at one end of the nut body 10 facing the mounted surface 30, a plate surface of the reinforcing surface 11 is perpendicular to an axial direction of the nut body 10, and the elastic piece 20 is formed on the reinforcing surface 11. Preferably, the plurality of elastic pieces 20, such as three, are uniformly arranged along the circumferential direction of the reinforcing surface 11 around the axis of the nut body 10.

With reference to fig. 3 and fig. 4, the reinforcing surface 11 is formed with a receiving hole 111, the elastic sheet 20 is disposed on the sidewall of the receiving hole 111 and extends out of the receiving hole 111, and when the locknut is fixed on the mounted surface 30, the elastic sheet 20 is compressed in the receiving hole 111 to ensure that the reinforcing surface 11 can be attached to the mounted surface 30. As shown in fig. 1, the elastic piece 20 extends toward the loosening direction of the locknut (the locknut shown in fig. 1 is a locknut adapted to a right-handed screw, i.e., clockwise is a tightening direction and counterclockwise is a loosening direction), that is, the elastic piece 20 extends toward the right side in fig. 1 in an adult. In the uncompressed state, the spring plate 20 is curved so as to bulge in the unscrewing direction. With this structure, when the locknut is rotated in the loosening direction spontaneously due to the vibration and the deformation of the mounting surface 30, the degree of deformation of the elastic piece 20 is increased by the force between the end of the elastic piece 20 and the mounting surface 30, and the elastic piece 20 can generate a certain resisting action when the locknut is loosened, which can prevent the nut from being "loosened by itself" due to an external force to some extent, and increase the fastening degree between the locknut and the mounting surface 30.

Fig. 5 is a schematic structural view of a cross section of the locknut along the axial direction thereof, and fig. 6 is a schematic structural view of the locknut and the bolt after being fixed. As shown in fig. 2, 5 and 6, a locking piece 12 is further provided on a side wall of the connection hole 14 where the nut body 10 and the bolt 40 are connected, and when the nut body 10 is fitted over the bolt 40, the locking piece 12 is engaged with a thread of the bolt 40. That is, in the present embodiment, the locking nut may be fixed by engaging the card 12 with the screw thread of the bolt 40, instead of providing the connecting hole 14 with the internal screw thread to which the bolt 40 is connected. When the locknut is installed, the nut body 10 is sleeved outside the bolt 40, and then the locknut is directly pushed towards the bolt 40, so that the nut body 10 is sleeved outside the bolt 40, and the clamping piece 12 is clamped on the thread of the bolt 40, and the assembly of the locknut and the bolt 40 can be completed. The arrangement enables the nut to no longer fit on the mounted surface 30 in a rotating manner, which can prevent the elastic sheet 20 from scratching the mounted surface 30 during the fastening process of the locknut, and can also be beneficial to better generate compression of the elastic sheet 20 during the assembly process of the locknut. The card 12 has a plurality of, for example 3, and a plurality of cards 12 are evenly arranged along the circumference of the connecting hole 14, and the ends of the plurality of cards 12 are all on the same plane. The diameter of the mounting hole (see D1 in fig. 2) formed between the ends of the plurality of cards 12 is approximately equal to the minor diameter of the bolt 40 to which the loose nut is fitted to facilitate the engagement of the cards 12 with the bolt 40.

Further, with continued reference to fig. 2 and 5, a plurality of limiting plates 13 are further disposed in the connecting hole 14, the limiting plates 13 are disposed on the side wall of the connecting hole 14 and extend along the axial direction of the nut body 10, and the plurality of limiting plates 13 are, for example, 3, and the plurality of limiting plates 13 are uniformly disposed along the circumferential direction of the connecting hole 14. The diameter of the pilot hole that forms between a plurality of limiting plates 13 slightly is greater than the major diameter with the bolt 40 of locknut adaptation, and when bolt 40 stretched into in the locknut, limiting plate 13 carried on spacingly to bolt 40, prevented that bolt 40 from rocking.

Further, the outer circumferential surface of the end surface of the nut body 10 is hexagonal, which enables the check bolt 40 to be quickly disassembled without being damaged using a conventional electric gun, enabling the check bolt 40 to be used many times.

As described above, in the present invention, by forming the elastic piece 20 on the end surface of the nut body 10 facing the end surface of the mounted surface 30, the elastic piece 20 is compressed when the nut body 10 is mounted on the mounted surface 30; as shown in fig. 4, once the mounted surface 30 deforms and a gap is formed between the mounted surface 30 and the nut body 10, the pressure applied to the elastic piece 20 is reduced, the elastic piece 20 continues to be pressed on the mounted surface 30 due to the restoring force generated by itself, and as long as the gap between the mounted surface 30 and the nut body 10 is not larger than the size of the deformation of the elastic piece 20 itself, the nut body 10 and the mounted surface 30 are always in the fit state, the torque of the nut is not seriously attenuated, and the looseness and abnormal noise are prevented.

The utility model also provides a vehicle, this vehicle include foretell locknut, about other technical characteristics of this vehicle, please see prior art, no longer give consideration to here.

The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiments, and although the present invention has been disclosed with the preferred embodiments, it is not limited to the present invention, and any skilled person in the art can make some modifications or equivalent changes without departing from the technical scope of the present invention.
