Description
Technical Field
[0001] This utility model relates to the field of brake fasteners, specifically a fastener for brakes. Background Technology
[0002] Brake fasteners are widely used in various motor vehicles, including cars, motorcycles, and trucks, as well as some industrial equipment and machinery that require braking devices. In automotive braking systems, in addition to fixing brake calipers, they are also used to connect brake discs to wheel hubs, brake lines to brake calipers, and other components. They are one of the key components that ensure the normal operation of the entire braking system.
[0003] In braking systems, fasteners play a crucial role in connecting and securing key components, and their performance directly affects the safety and reliability of the braking system. Traditional brake fasteners lack effective positioning structures during installation, making it difficult to accurately align components. This not only increases installation difficulty and time costs but may also affect the overall performance of the braking system due to improper installation. For example, when installing brake components, the inability to accurately position them may lead to uneven stress on the components, shortening their service life. Therefore, those skilled in the art have provided a brake fastener to solve the problems mentioned in the background art. Utility Model Content
[0004] The purpose of this invention is to provide a fastener for brakes to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A fastener for brakes includes a connecting slide column, a fastening bolt, and a locking nut adapted to the fastening bolt. The outer surface of the connecting slide column is slidably connected to two sliding brackets. One of the sliding brackets has a top connecting plate fixedly connected to its outer surface, and the other sliding bracket has a bottom connecting plate fixedly connected to its outer surface. The inner wall of the locking nut has an elastic locking ring fixedly connected to it. The outer surfaces of the top connecting plate and the bottom connecting plate are both provided with circular holes adapted to the fastening bolt.
[0007] As a further improvement of this utility model: the outer surface of the connecting slide column is provided with a guide groove, and the sliding frame is slidably connected to the guide groove.
[0008] As a further improvement of this utility model: the outer surface of the anti-loosening nut is provided with anti-slip texture, and the bottom end of the fastening bolt is provided with a chamfer.
[0009] As a further improvement of this utility model, positioning bosses are fixedly connected to the bottom surface of the top connecting plate and the upper surface of the bottom connecting plate.
[0010] As a further improvement of this utility model: a convex washer ring is fixedly connected to the bottom surface of the bottom connecting plate, and the convex washer ring is coaxial with the circular hole.
[0011] As a further improvement of this utility model, the outer surfaces of the top connecting plate, the bottom connecting plate, the fastening bolts, the anti-loosening nuts, the connecting slide column, and the sliding frame are all coated with an anti-rust coating.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] The fasteners used in this brake system have an elastic anti-loosening ring on the inner wall of the anti-loosening nut that fits tightly against the fastening bolt. The friction generated by the elastic deformation effectively prevents the nut from loosening. Under the vibration of the vehicle during driving and the impact of braking, the elastic anti-loosening ring can maintain the tightening force on the bolt, ensuring the connection of the brake components is stable and improving the safety of the braking system.
[0014] The fasteners for this brake can be quickly and accurately positioned by locating bosses on the top and bottom connecting plates that mate with corresponding grooves on the brake components, simplifying the installation process. At the same time, the sliding engagement between the connecting column and the sliding bracket allows for easy adjustment of the connecting plate position to adapt to different installation requirements, achieving convenient installation and precise positioning, and improving installation efficiency.

[0023] Please see Figures 1-5In this embodiment of the present invention, a fastener for a brake includes a connecting slide column 4, a fastening bolt 3, and an anti-loosening nut 2 adapted to the fastening bolt 3. Two sliding frames 5 are slidably connected to the outer surface of the connecting slide column 4. A top connecting plate 1 is fixedly connected to the outer surface of one sliding frame 5, and a bottom connecting plate 7 is fixedly connected to the outer surface of the other sliding frame 5. An elastic anti-loosening ring 12 is fixedly connected to the inner wall of the anti-loosening nut 2. Circular holes 9 adapted to the fastening bolt 3 are provided on the outer surfaces of both the top connecting plate 1 and the bottom connecting plate 7. The sliding connection between the connecting slide column 4 and the sliding frames 5 allows for adjustment of the connecting plate position. The top connecting plate 1 and the bottom connecting plate 7 are used to connect brake components. The fastening bolt 3 and the anti-loosening nut 2 secure the components. The elastic anti-loosening ring 12 enhances the anti-loosening performance. The elastic anti-loosening ring 12 is made of high-strength rubber or nylon, which has good elasticity and wear resistance. The inner diameter of the elastic anti-loosening ring 12 is slightly smaller than the minor diameter of the nut's internal thread. When the anti-loosening nut 2 is tightened, the elastic anti-loosening ring 12 will be squeezed and produce radial elastic deformation, which will fit tightly with the thread of the fastening bolt 3 to form friction, thereby playing an anti-loosening role. The circular hole 9 facilitates the bolt to pass through and achieve connection. Example: When installing brake components, the top connecting plate 1 and the bottom connecting plate 7 are put on the connecting slide column 4 through the sliding bracket 5 and adjusted to a suitable position. The fastening bolt 3 is passed through the circular hole 9 and the anti-loosening nut 2 is screwed on. The elastic anti-loosening ring 12 tightly holds the fastening bolt 3 to ensure that the brake components are firmly connected. For example, when installing car brake pads, the connection and fixation of the brake pads and brake calipers can be completed quickly.
[0024] A guide groove 6 is provided on the outer surface of the connecting slide column 4, and the sliding frame 5 is slidably connected to the guide groove 6. The guide groove 6 provides guidance for the sliding of the sliding frame 5, ensuring that the sliding frame 5 slides smoothly on the connecting slide column 4 and preventing the sliding frame 5 from shifting or tilting during movement. This allows the top connecting plate 1 and the bottom connecting plate 7 to be accurately adjusted to the predetermined position, improving installation accuracy. In the embodiment, when adjusting the position of the top connecting plate 1 and the bottom connecting plate 7, the sliding frame 5 slides along the guide groove 6 on the connecting slide column 4, ensuring that the connecting plate moves smoothly. The outer surface of the anti-loosening nut 2 is provided with anti-slip texture 11, and the bottom end of the fastening bolt 3 is provided with a chamfer 13. The anti-slip texture 11 on the outer surface of the anti-loosening nut 2 increases friction and improves operational convenience. The chamfer 13 at the bottom end of the fastening bolt 3 facilitates the bolt to pass smoothly through the circular hole 9, reducing installation resistance and making the installation process smoother. The optimal chamfer angle for the chamfer 13 is 10°-15°.
[0025] Positioning bosses 8 are fixedly connected to the bottom surface of the top connecting plate 1 and the upper surface of the bottom connecting plate 7. The positioning bosses 8 cooperate with the corresponding grooves on the brake components to be fastened, so as to achieve precise positioning of the top connecting plate 1 and the bottom connecting plate 7, ensure the accurate installation position of the brake components, avoid uneven force on the components due to misalignment, and improve the overall performance and reliability of the braking system. A convex washer ring 10 is fixedly connected to the bottom surface of the bottom connecting plate 7, and the convex washer ring 10 is coaxial with the circular hole 9. The convex washer ring 10 increases the contact area between the bottom connecting plate 7 and the connecting components, disperses the pressure generated by the fastening bolts 3, and prevents stress concentration at the connection point. Meanwhile, the convex washer ring 10 is coaxial with the circular hole 9, ensuring that the bolt is subjected to uniform force and further improving the stability of the connection. The outer surfaces of the top connecting plate 1, the bottom connecting plate 7, the fastening bolt 3, the anti-loosening nut 2, the connecting slide column 4, and the sliding frame 5 are all coated with anti-rust coating. The anti-corrosion coating has good wear resistance and weather resistance. The anti-rust coating effectively protects the fastener components from the damage of dust, water vapor, oil and other corrosive media, extends the service life of the fastener, reduces the maintenance and replacement costs caused by component corrosion, and ensures the long-term stable operation of the braking system.
[0026] The working principle of this utility model is as follows: First, according to the different thicknesses of the fasteners, push the adjusting sliding frame 5 to slide along the connecting sliding column 4 and the guide groove 6. When the two sliding frames 5 move respectively, they can move the top connecting plate 1 and the bottom connecting plate 7 up and down respectively. After adjusting to the appropriate thickness, the top connecting plate 1 is attached to the top of the fastener, and the bottom connecting plate 7 is attached to the bottom surface of the fastener. Then, the fastening bolt 3 is passed through the top connecting plate 1 and the bottom connecting plate 7 in sequence. The chamfer 13 is used to quickly align the holes of the top connecting plate 1 and the bottom connecting plate 7. Then, the anti-loosening nut 2 is screwed into the end of the fastening bolt 3. The elastic anti-loosening ring 12 is deformed by pressure to generate a continuous locking force, preventing the anti-loosening nut 2 from falling back, so as to achieve the purpose of a stable connection.
