Description

Technical Field

[0001] This utility model belongs to the field of bicycle accessories technology, and in particular relates to a bicycle disc brake disc fixing and locking structure. Background Technology

[0002] A bicycle disc brake is a component of the bicycle's braking system. When braking, the brake pads clamp the brake disc to generate friction, thereby achieving the braking effect. Current disc brake fixing structures that reduce bolt stress include an end cap. The end cap has a first locking element at its center, multiple sets of circularly arranged connecting buckles on its front side, a disc brake body on its front side, a connecting disc fixed to its back, and a second locking element penetrating the connecting disc on its front side. While this bicycle disc brake fixing and locking structure can limit the movement of the hub and brake disc through the locking mechanism, the bolts are still subject to vibration during riding, posing a risk of loosening or even falling off. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a bicycle disc brake fixing and locking structure, which limits the bolts after installation and avoids the risk of the bolts loosening or even falling off due to vibration during riding.

[0004] This utility model is achieved through the following technical solution: A bicycle disc brake disc fixing and locking structure includes a disc brake disc with a hollowed-out section inside. A fixing seat assembly is arranged in a ring around the center of the disc brake disc, with the ring of the fixing seat assembly coaxial with the center of the disc brake disc. The fixing seat assembly includes a hollow fixing post with a receiving hole inside. A locking bolt is installed inside the hollow fixing post. A slot is provided on the lower side of the hollow fixing post. A side hollow fixing post is integrally formed on the upper part of the hollow fixing post. A stop bar is passed through the side hollow fixing post, with its lower end extending into the receiving hole. An insert post is integrally formed on the lower end of the stop bar, engaging with the slot. A pull plate is integrally formed on the upper part of the side hollow fixing post. A tension spring is sleeved on the outside of the portion of the stop bar inside the side hollow fixing post.

[0005] Preferably, the number of the fixing base assemblies is set to at least three.

[0006] Preferably, one end of the tension spring is fixed to the tension plate, and the other end is fixed to the hollow fixing post.

[0007] Preferably, a groove is provided on one side of the pull plate.

[0008] Preferably, the plurality of hollow fixing posts are integrated with the disc brake disc.

[0009] Preferably, the disc brake disc has a through hole inside the position where the hollow fixing post is installed, and the through hole is used to pass through the locking bolt.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, the hollow fixing post 31, receiving hole 32, locking bolt 33, slot 34, side hollow fixing post 35, stop bar 36, insert post 37, pull plate 38, groove 39, and tension spring 310 are designed to prevent the locking bolt 33 from loosening or even falling off due to vibration during riding, making the installation more secure and improving the safety performance of the bicycle.

[0013] The present invention will now be described in detail with reference to the accompanying drawings. As shown in Figure 1, a bicycle disc brake fixing and locking structure includes a disc brake disc 1. The disc brake disc 1 has a hollowed-out portion 2 inside. A fixing seat assembly 3 is arranged in a ring in the middle of the disc brake disc 1. The ring of the fixing seat assembly 3 is arranged coaxially with the center of the disc brake disc 1.

[0014] In this implementation plan, in conjunction with the appendix Figure 2 As shown, the fixing base assembly 3 includes a hollow fixing post 31, with a receiving hole 32 inside the hollow fixing post 31. A locking bolt 33 is installed inside the hollow fixing post 31, and a slot 34 is provided on the lower side inside the hollow fixing post 31. A side hollow fixing post 35 is integrally provided on the upper part of the hollow fixing post 31. A stop bar 36 is provided through the interior of the side hollow fixing post 35. The lower end of the stop bar 36 extends into the receiving hole 32. An insert post 37 is integrally provided on the lower end of the stop bar 36. The insert post 37 is configured to cooperate with the slot 34. A pull plate 38 is integrally provided on the upper end of the stop bar 36. The pull plate 38 is located on the upper part of the side hollow fixing post 35. A tension spring 310 is sleeved on the outside of the part of the stop bar 36 inside the side hollow fixing post 35.

[0015] In this embodiment, specifically, the number of the fixing base assembly 3 is set to at least three.

[0016] In this embodiment, specifically, one end of the tension spring 310 is fixed to the tension plate 38, and the other end is fixed to the hollow fixing post 31.

[0017] In this embodiment, specifically, a groove 39 is provided on one side of the pull plate 38.

[0018] In this embodiment, specifically, the plurality of hollow fixing posts 31 are integrated with the disc brake disc 1.

[0019] In this embodiment, specifically, a through hole is provided inside the position where the hollow fixing post 31 is installed on the disc brake disc 1, and the through hole is used to pass through the locking bolt 33.

[0020] Working principle In this invention, when fixing the disc brake disc 1 to the bicycle hub, the user first inserts one end of an external flathead screwdriver or other tool into the groove 39 to open the pull plate 38. The user then pulls the pull plate 38, pulling the stop lever 36 and the insert post 37 outwards, so that the stop lever 36 does not obstruct the installation of the locking bolt 33. The locking bolt 33 is then installed using an external tool, fixing the hollow fixing post 31, the disc brake disc 1, and the bicycle hub. After fixing, the pull plate 38 is released, and under the tension of the tension spring 310, the stop lever 36 is reset. At this time, the insert post 37 enters the slot 34, making the stop lever 36 more stable. The stop lever 36 limits the locking bolt 33, preventing vibration during riding from causing the locking bolt 33 to loosen or even fall off. The installation is more secure, improving the safety performance of the bicycle.

[0021] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution of this utility model, falls within the protection scope of this utility model.
