Description

Technical Field

[0001] The utility model relates to the technical field of a novel special nut for locking a wheel hub of an automobile, in particular to a special nut for locking a wheel hub of an automobile. Background Art

[0002] Nuts are common in daily life and are used as a part of mechanical connections. However, when nuts are installed for a long time under vibration conditions,

[0003] The nuts may loosen due to vibration or movement of the fasteners. If the nuts are installed for a long time, they may loosen due to vibration or movement of the fasteners. Ordinary nuts often loosen by themselves, or the nut connection will fail and the fixation will be unstable when the force on the screws is uneven. In order to solve the problem of loosening of threaded fasteners, people have adopted various methods, such as inserting pins, adding anti-rotation lock plates and adding fixing facilities. These solutions can solve some of the anti-loosening problems, but they are not convenient for removal and reuse.

[0004] Application number CN202110758386.2 discloses a kind of anti-loosening nut, including: a nut body, a limiting pin and a spherical body; the nut body is formed with a threaded hole, and is formed with an axial through hole and a radial through hole arranged orthogonally, the axial through hole is used to install the limiting pin, and the radial through hole is connected with the threaded hole for installing the spherical body; the diameter of the radial through hole is larger than the diameter of the spherical body, the diameter of the spherical body is larger than the maximum diameter of the limiting pin, and is larger than the distance from the inner side of the radial through hole to the bottom of the thread groove in the threaded hole; the diameter of the axial through hole is the same as the maximum diameter of the limiting pin; when the limiting pin is pressed into the first position in the axial through hole, the tightening between the screw and the nut body is achieved; when the limiting pin is pressed into the second position of the axial through hole, the extrusion of the screw is released. The present invention can not only lock the nut to prevent the nut from loosening, but also be conveniently removed as needed.

[0005] The above document discloses that the special nut for locking the automobile wheel hub has a sinking problem; the above document adds a steel ball in the hole column to position and lock the nut, which may cause wear on the nut and may cause excessive stress in the through hole, resulting in stress concentration at the through hole, causing cracks or splitting, thereby making the locking and fixing of the nut ineffective or scrapped. At the same time, the increase of accessories will also complicate the use method, increase the labor intensity of workers, and increase the processing cost.

[0006] It can be seen from this that the existing anti-loosening nut assembly has great defects, and it is necessary to improve the existing deficiencies and provide a special nut for locking the automobile wheel hub. Summary of the invention

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0009] Furthermore, a circular gasket is rubber-mounted on the top surface of the second contraction column of the upper limit spring column.

[0010] Furthermore, the lower part of the nut body is provided with a fitting part, the inside of which is a threaded through hole of the fitting part, the lower through hole of the rubber gasket transverse through hole is provided with a pad column on the side of the through hole of the fitting part away from the nut body, and the top surface of the pad column is located above the transverse through hole and is a threaded hole.

[0011] Further, the upper part of the vertical through hole is provided with a limit spring column, which is composed of an upper second contraction column and an upper spring around the second contraction column. The lower part of the vertical through hole is provided with a limit spring column, which is composed of a lower spring around the first contraction column and the second contraction column.

[0012] Furthermore, a pad column is installed on the lower through hole of the transverse through hole, and the top surface of the pad column is located at the upper part of the transverse through hole, which is a threaded hole and achieves a good locking effect.

[0013] The utility model has the following beneficial effects:

[0014] The utility model realizes the tightening between the screw rod and the nut body by pressing the limit spring column into the first position in the transverse through hole; at the same time, as the screw rod rotates in the transverse screw hole, the limit spring rod in the vertical through hole will be squeezed and contracted, and the screw rod will be locked and fixed, and at the same time, the pad column in the lower half of the transverse through hole will be squeezed by the screw rod to buckle and fix the screw in the nut body.

[0015] (2) The utility model makes the threaded through hole of the fitting part have the same inner diameter as the threaded through hole of the nut body but has a denser number of thread turns than the threaded through hole of the threaded body, so that the screw rod in the nut body can better fit the nut and have a good fixing effect.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
