Description

An adjusting screw and handle Technical Field

[0001] This utility model relates to the field of brake lever technology, and more specifically, to an adjusting screw and a lever. Background Technology

[0002] Brake levers are key components on bicycles, motorcycles, and other vehicles used to operate the braking system. They are typically mounted on either side of the handlebars for easy hand operation by the rider. Their core function is to transfer the force applied by the hand to the braking device through leverage, causing the wheels to slow down or stop. With technological advancements, brake levers are constantly being improved. Some high-end products utilize lightweight materials such as aluminum alloys and carbon fiber, reducing weight while maintaining strength.

[0003] Traditional brake cables require threading through a mounting bracket and tightening directly with screws. This installation process necessitates repeated adjustments to the cable length and angle, requiring the user to bend over to the wheel 3-5 times to loosen or loosen the cable. After each adjustment, the user must test the brake feel while riding the vehicle, making the installation cumbersome and time-consuming. Therefore, we propose an adjustment screw and handle. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an adjusting screw and handle to solve the technical problems of cumbersome installation and time-consuming adjustment of the brake cable.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an adjusting screw and handle, including an adjusting mechanism, the adjusting mechanism including a threaded tube and a limiting ring, the outer surface of the threaded tube is provided with threads, the end of the threaded tube is integrally formed with a rotating tube, the outer surface of the threaded tube is provided with a first wire inlet notch along the long axis direction, the rotating tube is provided with a second wire inlet notch along the long axis direction, the first wire inlet notch and the second wire inlet notch are connected, the limiting ring is threadedly installed on the outer surface of the threaded tube, the limiting ring is provided with a third wire inlet notch, the width of the third wire inlet notch is the same as the width of the first wire inlet notch.

[0006] Preferably, the outer surface of the rotating tube is provided with a first groove, and the first groove forms a first anti-slip texture on the outer surface of the rotating tube.

[0007] Preferably, the outer surface of the limiting ring is provided with a second slot, and the second slot forms a second anti-slip texture on the outer surface of the limiting ring.

[0008] A handle includes the aforementioned adjusting screw and a handle mechanism. The handle mechanism includes a mounting base and a pressing handle rotatably mounted on the mounting base. A mounting groove is provided on one side of the upper end face of the mounting base, and a threaded hole communicating with the mounting groove is provided at the front end of the mounting base. The size of the threaded hole is adapted to the size of the threaded tube, and a fifth inlet notch communicating with the threaded hole is provided at the upper end of the mounting base.

[0009] Preferably, the front part of the pressing handle has a fourth inlet notch corresponding to the fifth inlet notch, and the rear part of the pressing handle has a fixing hole communicating with the fourth inlet notch.

[0010] Preferably, the rear end of the mounting base is provided with a sleeve, a pneumatic rod is fixedly sleeved inside the sleeve, a lifting plate is provided at the rear end of the front part of the pressing handle, and the piston rod end of the pneumatic rod contacts the lifting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model features interconnected cable entry notches on the threaded tube, rotating tube, and limiting ring of the adjusting screw, along with corresponding cable entry notches on the mounting base and press handle. This allows the brake cable to pass directly from the outside through a continuous channel into the mounting base and into the fixing hole of the press handle for fixation. Furthermore, since the threaded tube and the threaded hole on the mounting base are threadedly connected, the user can manually rotate the rotating tube of the threaded tube. Utilizing the thread transmission principle, the threaded tube extends outward or retracts inward into the threaded hole, thus quickly adjusting the length of the brake cable. After adjustment, rotating the limiting ring ensures a tight fit with the mounting base, locking the position of the threaded tube. This eliminates the need for the user to bend over to the wheel and make multiple adjustments during traditional adjustments. After each adjustment, the user can easily test the brake feel by riding the vehicle, significantly reducing the time required for brake cable adjustment, greatly simplifying the installation process, significantly shortening the installation time, and reducing the complexity of the installation operation. This solves the technical problems of cumbersome brake cable installation and time-consuming brake cable adjustment.

[0013] 2. This utility model also incorporates a pneumatic rod and lifting plate structure. The pneumatic rod inside the sleeve at the rear end of the mounting base cooperates with the lifting plate at the front and rear ends of the pressing handle to provide assistance during braking. When the rider presses the pressing handle, the piston rod of the pneumatic rod extends under air pressure, overcoming the tension of the brake cable, and pushes the lifting plate. This causes the pressing handle to rotate around its rotating connection with the mounting base, pulling the brake cable to achieve braking. This process reduces the force required for the rider to press the handle, making braking easier and smoother, reducing hand fatigue, and improving riding comfort. At the same time, stable and easy braking operation also helps the rider control the brakes more promptly and accurately, improving riding safety. Attached Figure Description

Detailed Implementation

[0022] Example 1: As shown in Figures 1 to 7, this utility model relates to an adjusting screw and handle, including an adjusting mechanism 100. The adjusting mechanism 100 includes a threaded tube 101 and a limiting ring 103. The outer surface of the threaded tube 101 is provided with threads, and a rotating tube 102 is integrally formed at the end of the threaded tube 101. A first wire inlet notch 1011 is opened on the outer surface of the threaded tube 101 along the long axis direction, and a second wire inlet notch 1021 is opened on the rotating tube 102 along the long axis direction. The first wire inlet notch 1011 and the second wire inlet notch 1021 are connected. The limiting ring 103 is threadedly installed on the outer surface of the threaded tube 101, and a third wire inlet notch 1031 is opened on the limiting ring 103. The width of the third wire inlet notch 1031 is the same as the width of the first wire inlet notch 1011. The threaded tube 101 can be threaded into the threaded hole at the upper front end of the mounting base 202. By rotating it, the third inlet notch 1031 of the limiting ring 103 aligns with the first inlet notch 1011. When installing the brake cable, it can directly enter through the first inlet notch 1011, the second inlet notch 1021, the third inlet notch 1031, and the fifth inlet notch 2021 and pass through the mounting base 202. The end of the brake cable enters the fixing hole 2012 through the fourth inlet notch 2011 and is fixed with a screw, which can quickly complete the installation of the brake cable. After installation, rotating the limiting ring 103 to misalign the third inlet notch 1031 with the other inlet notches can prevent the brake cable from coming off. During use, manually rotating the threaded tube 101 to extend it outward or retract it inward can directly adjust the length of the brake cable. After adjusting the length, tighten the limiting ring 103 to lock the threaded tube 101.

[0023] Specifically, the outer surface of the rotating tube 102 is provided with an array of first slots, which form a first anti-slip texture 1022 on the outer surface of the rotating tube 102. The first anti-slip texture 1022 allows the threaded tube 101 to be rotated manually.

[0024] Furthermore, the outer surface of the limiting ring 103 is arrayed with a second slot, which forms a second anti-slip texture 1032 on the outer surface of the limiting ring 103. The second anti-slip texture 1032 facilitates manual rotation of the limiting ring 103.

[0025] Example 2

[0026] A handle includes the aforementioned adjusting screw and a handle mechanism 200. The handle mechanism 200 includes a mounting base 202 and a press handle 201 rotatably mounted on the mounting base 202. A mounting groove 2022 is formed on one side of the upper end face of the mounting base 202. A threaded hole communicating with the mounting groove 2022 is formed at the front end of the mounting base 202. The size of the threaded hole is adapted to the size of the threaded tube 101. A fifth cable inlet notch 2021 communicating with the threaded hole is formed at the upper end of the mounting base 202. The fifth cable inlet notch 2021 allows the brake cable to easily enter and pass through the mounting base 202 from the outside.

[0027] It is worth noting that the front of the press handle 201 has a fourth wire inlet notch 2011 corresponding to the fifth wire inlet notch 2021, and the rear of the press handle 201 has a fixing hole 2012 communicating with the fourth wire inlet notch 2011. The fourth wire inlet notch 2011 facilitates the entry of the brake cable into the fixing hole 2012, and the end of the brake cable can be fixed by installing a screw in the fixing hole 2012.

[0028] It is worth mentioning that the rear end of the mounting base 202 is provided with a sleeve 203, and a gas spring 204 is fixedly fitted inside the sleeve 203. A lifting plate 2013 is provided at the rear end of the front part of the pressing handle 201, and the end of the piston rod of the gas spring 204 contacts the lifting plate 2013. When no pressure is applied to the pressing handle 201, the tension of the brake cable allows the lifting plate 2013 to compress the piston rod of the gas spring 204, keeping the piston rod of the gas spring 204 always within the gas spring 204. When braking is required, the rider manually presses the pressing handle 201, causing the piston rod of the gas spring 204 to extend against the tension of the brake cable under air pressure. The lifting plate 2013 pushes the pressing handle 201 to rotate around its rotatable connection with the mounting base 202, thereby pulling the brake cable and applying the brakes. The tension transmitted by the brake cable causes the braking device to apply braking force to the wheels, thereby slowing down or stopping the vehicle. During braking, the air rod 204 provides assistance, making the operation of pressing the handle 201 easier and smoother, while also reducing hand fatigue and improving riding comfort and safety. After braking, when the handle 201 is released, the return tension of the brake cable causes the lifting plate 2013 to press the piston rod of the air rod 204 to retract, and the handle 201 returns to its original position, preparing for the next braking operation.

[0029] Working principle: This embodiment provides an adjusting screw and handle. When installing the brake cable, first, the threaded tube 101 is threaded into the threaded hole at the upper front end of the mounting base 202. Then, the threaded tube 101 is rotated so that the third inlet notch 1031 of the limiting ring 103 corresponds to the first inlet notch 1011 of the threaded tube 101. At this time, the first inlet notch 1011, the second inlet notch 1021, the third inlet notch 1031, and the fifth inlet notch 2021 on the mounting base 202 form a continuous channel. The brake cable can pass directly through this channel from the outside through the mounting base 202, and then enter the fixing hole 2012 at the rear end through the fourth inlet notch 2011 at the front of the handle 201. Finally, the cable enters the fixing hole 2012 at the rear end through the fixing hole 2012. The brake cable end is secured with an internal screw, thus quickly completing the brake cable installation. After installation, rotate the limiting ring 103 to misalign the third wire inlet notch 1031 with other wire inlet notches. At this time, the limiting ring 103 acts as a limit for the brake cable, preventing it from detaching. If the length of the brake cable needs to be adjusted, since the threaded tube 101 is threadedly connected to the threaded hole on the mounting base 202, the rotating tube 102 of the threaded tube 101 can be manually rotated. Utilizing the thread transmission principle, the threaded tube 101 extends outward or retracts inward from the threaded hole. When the threaded tube 101 moves, the length of the connected brake cable also changes accordingly. After adjusting to the appropriate brake cable length, manually rotate the limiting ring 103 to align it with the mounting base 202. The tight fit locks the position of the threaded tube 101, allowing for adjustment of the brake cable length. The first anti-slip texture 1022 on the outer surface of the rotating tube 102 and the second anti-slip texture 1032 on the outer surface of the limiting ring 103 effectively increase friction, facilitating rotation. During use, when no pressure is applied to the pressing handle 201, the lifting plate 2013 at the front and rear ends of the pressing handle 201 compresses the piston rod of the air rod 204 under the tension of the brake cable, causing the piston rod of the air rod 204 to retract inside the air rod 204. When the rider needs to brake, they manually press the pressing handle 201. At this time, the air pressure inside the air rod 204 changes, and under the action of air pressure, the piston rod of the air rod 204 overcomes the tension of the brake cable. Extending the push plate 2013 pushes the push handle 201 to rotate around its rotatable connection with the mounting base 202, pulling the brake cable. The brake cable transmits the tension to the braking device, causing the braking device to apply braking force to the wheels, thus slowing down or stopping the vehicle. During this process, the air rod 204 provides assistance, reducing the force required for the rider to press the handle, making braking operation easier and smoother, reducing hand fatigue, and improving riding comfort and safety. After braking, releasing the push handle 201 causes the push plate 2013 to press the piston rod of the air rod 204 back under the return tension of the brake cable, and the push handle 201 returns to its original position, preparing for the next braking operation.
