Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to a fastening nut based on an automotive braking module. Background Art

[0002] The fastening nuts of automotive braking modules are mainly used to fix key components of the braking system, such as brake calipers, brake discs, etc., to ensure that these components can remain stable during vehicle driving, thereby achieving an effective braking effect; traditional nuts are nut bodies provided with internal threaded holes, and their fastening effect completely depends on the tightening of the threads.

[0003] In view of the above related technologies, the inventor found that due to the large bumps and vibrations that are likely to occur during vehicle driving, there is a phenomenon of loosening of the connection between the nut and the bolt, which reduces the use effect. Therefore, it is necessary to design a nut with an anti-loosening function to reduce the failures caused by the loosening of the fastening nut during vehicle driving. Summary of the Utility Model

[0004] The main technical problem to be solved by the utility model is to provide a fastening nut based on an automotive braking module. Rotating and squeezing the nut body drives the moving ring to axially move, and the moving ring drives the small-diameter end of the conical elastic hoop assembly to contract and hold the bolt tightly, achieving the purpose of anti-loosening and enhancing the use effect.

[0005] To solve the above technical problem, a technical solution adopted by the utility model is: to provide a fastening nut based on an automotive braking module, including: a nut body, one end of the nut body is connected with a round tube body, the end of the round tube body away from the nut body is connected with a conical guiding housing groove assembly, the conical guiding housing groove assembly includes a conical guiding groove, the outer circle of the round tube body is threadedly connected with a squeezing nut body, a moving ring is arranged on the side of the squeezing nut body away from the nut body, the moving ring is sleeved on the outer circle of the round tube body, and the side of the moving ring away from the squeezing nut body is connected with a conical elastic hoop assembly passing through the conical guiding groove.

[0006] By adopting the above technical solution, when the fastening nut is used on an automotive braking module, after the fastening nut is threadedly connected with the bolt, the end of the fastening nut away from the round tube body is in close contact with the fastened part, achieving the purpose of fastening. At this time, rotating and squeezing the nut body moves towards the moving ring, and the squeezing nut body drives the moving ring and the conical elastic hoop assembly to axially move. Since the conical elastic hoop assembly passes through the conical guiding groove of the conical guiding housing groove assembly, the small-diameter end of the conical elastic hoop assembly is contracted and held tightly on the bolt, achieving the purpose of anti-loosening and enhancing the use effect.

[0007] In a preferred embodiment, the present utility model can be further configured as follows: the conical guide housing groove assembly includes an outer conical housing and an inner conical housing disposed in its inner cavity. A conical guiding groove is provided between the inner conical housing and the outer conical housing. A plurality of connecting blocks are annularly arrayed and connected between the large-diameter ends of the inner conical housing and the outer conical housing. The large-diameter end of the inner conical housing is connected to the end of the circular tube.

[0008] By adopting the above technical solution, the outer conical housing and the inner conical housing are indirectly fixedly connected through the connecting blocks connected between the inner conical housing and the outer conical housing.

[0009] In a preferred embodiment, the present utility model can be further configured as follows: the conical elastic retaining hoop assembly includes V-shaped spring steel sheets respectively inserted between adjacent connecting blocks. One end of the V-shaped spring steel sheet is connected to the moving ring, and the other end passes through the conical guiding groove.

[0010] By adopting the above technical solution, the V-shaped spring steel sheet is inserted into the conical guiding groove. The end of the V-shaped spring steel sheet far from the moving ring extends to the outside of the conical guiding groove and is tightly connected to the bolt, achieving the purpose of clamping the bolt, that is, having an anti-loosening effect.

[0011] In a preferred embodiment, the present utility model can be further configured as follows: the inner diameter of the small-diameter end of the inner conical housing is larger than the major diameter of the internal thread in the nut body.

[0012] By adopting the above technical solution, since the inner diameter of the small-diameter end of the inner conical housing is larger than the major diameter of the internal thread in the nut body, the problem of interference between the inner conical housing and the bolt is prevented.

[0013] In a preferred embodiment, the present utility model can be further configured as follows: thread sealant is applied to the threaded connection between the extrusion nut body and the circular tube.

[0014] By adopting the above technical solution, by applying thread sealant to the threaded connection between the extrusion nut body and the circular tube, the stability of the threaded connection between the extrusion nut body and the circular tube is enhanced.

[0015] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0016] By driving the moving ring and the conical elastic retaining hoop assembly to axially move through the extrusion nut body, a plurality of V-shaped spring steel sheets on the conical elastic retaining hoop assembly pass through the conical guiding groove and are tightly connected to the bolt, achieving the purpose of clamping the bolt, that is, the bolt has an anti-loosening function, enhancing the use effect.
