Description

Technical Field

[0001] The utility model relates to the field of brake devices, in particular to a brake line connecting mechanism. Background Art

[0002] The brake cable is a key component connecting the brake handle and the brake device. When the brake handle is pulled, the brake cable will transfer force to the brake device to achieve the braking function. The brake handle is the direct component for the rider to operate the brake. The braking force is controlled by pulling the brake handle. The brake device usually includes brake shoes or brake pads. These components contact the wheel or brake disc when braking, and slow down the rotation speed of the wheel through friction. In the wire brake system, the brake device is usually activated by the tension of the brake cable.

[0003] During the installation and use of existing brake cables, the brake cable is usually passed through the through hole of the rotating seat on the rotating arm, and an adjusting nut is threadedly connected to the end of the brake cable. When braking, the rotating arm can be driven to rotate by the traction of the brake cable, thereby realizing the braking operation. However, when the brake cable needs to be inspected or separated from the rotating arm, the adjusting nut must be removed first. Similarly, the nut needs to be reinstalled and adjusted during the installation process. This operation of repeatedly twisting the adjusting nut significantly reduces the convenience of brake cable installation. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a brake line connection mechanism to solve the technical problem that the operation of twisting and re-tightening the adjusting nut reduces the convenience of brake line installation.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a brake line connecting mechanism, comprising a side plate, a rotating arm and a brake line, the rotating arm being connected to the brake line through a connecting mechanism, the connecting mechanism comprising a rotating seat, a movable plate and a pressure plate being arranged inside the rotating seat, a support rod being arranged between the movable plate and the pressure plate, a limiting rod being arranged on one side of the movable plate, a pressure spring being arranged on the other side of the movable plate, and a slot being arranged on the rotating seat.

[0006] By adopting the above technical solution, as the pressure gradually increases, the pressure plate, the support rod and the movable plate will overcome the elastic force of the pressure spring and move, so that the limit rod is moved to one side. In this way, the brake line can be easily detached from the rotating seat from the opening side of the slot, thereby eliminating the complicated operation of removing the adjusting nut at the end of the brake line.

[0007] Furthermore, the rotating seat passes through the rotating arm through a through hole, and the brake line is rotatably connected to the rotating arm through the rotating seat.

[0008] By adopting the above technical solution, the brake line can be firmly connected to the rotating arm through this structure. This connection method not only ensures the stability of the brake line when transmitting braking force, but also ensures that the rotational force can be effectively transmitted from the brake line to the rotating arm.

[0009] Furthermore, the limit rod is used to limit the position of the brake line, and the end of the brake line is threadedly connected with an adjusting nut.

[0010] By adopting the above technical solution, it is ensured that the brake line always remains stable during use and will not shift due to external factors or braking operations, thereby improving the accuracy and reliability of braking.

[0011] Furthermore, the pressure spring is used to provide a rebound support force for the limiting rod, and the other end of the pressure spring abuts against the inner wall of the rotating seat.

[0012] By adopting the above technical solution, it is ensured that the limit rod can quickly and accurately return to the initial position after being acted upon by an external force, which helps to maintain the stability and reliability of the brake line and prevent it from shifting due to external interference.

[0013] Furthermore, one side of the slot is in an open structure for installing a brake line.

[0014] By adopting the above technical solution, it provides great convenience for the installation of the brake line. The opening structure enables the brake line to be easily put into the slot from the opening, which simplifies the installation steps and improves work efficiency.

[0015] Furthermore, a limiting cover is detachably connected to one side of the rotating seat for limiting the positions of the pressing plate and the movable plate, and a fixing plate is arranged on the other side of the rotating seat.

[0016] By adopting the above technical solution, the limiting cover can effectively limit the position of the pressure plate and the movable plate, ensuring that these components remain stable during operation and will not accidentally move or misalign.

[0017] Furthermore, an opening is provided at the center axis of the limit cover, for an external rod-shaped tool to pass through the opening to apply a pressing force to the pressing plate.

[0018] By adopting the above technical solution, the opening provides a convenient access point for external rod-shaped tools, which enables maintenance personnel to easily use the tools to penetrate the opening and directly apply a pressing force to the pressure plate.

[0019] Furthermore, a fixing plate is provided on one side of the surface of the side plate, and the brake line is engaged with the fixing plate.

[0020] By adopting the above technical solution, a stable engagement point is provided for the brake cable, which enables the brake cable to be firmly engaged with the fixing plate, ensuring that the brake cable will not shake or fall off during riding and use, and providing a certain installation support force for the brake cable.

[0021] Furthermore, a tension spring is arranged on the outer side of the brake line, and the side plate is connected to the frame via a mounting shaft.

[0022] By adopting the above technical solution, the tensioning spring can always keep the brake line in a tensioned state, which ensures that the brake line will not affect the braking effect due to relaxation when transmitting braking force, thereby improving the sensitivity and reliability of the brake.

[0023] In summary, the utility model mainly has the following beneficial effects:

[0024] 1. The utility model uses a connecting mechanism and a gradually increasing pressing force to enable the pressing plate, the support rod and the movable plate to overcome the elastic force of the pressure spring and move their positions until the limit rod is pushed to one side. This unique design significantly simplifies the disassembly process of the brake line, because at this time the brake line can be easily separated from the rotating seat directly from the opening side of the slot, thereby avoiding the cumbersome operation of removing the adjusting nut at the end of the brake line. At the same time, the setting of the mechanism also greatly improves the convenience of installing and removing the brake line. During the installation process, the brake line can be easily put into the slot by simply pressing the pressing plate. Then, the pressing force of the pressure spring will push the limit rod to automatically reset, thereby effectively limiting the brake line and quickly completing the installation process. This not only reduces the operating steps, but also saves valuable time, and significantly improves the efficiency of installing and removing the brake line.

[0025] 2. The utility model provides a limit cover. The limit cover detachably connected to one side of the rotating seat can effectively limit the positions of the pressure plate and the movable plate, which provides structural stability and reliability. The detachable connection structure of the limit cover facilitates future maintenance and replacement. At the same time, the fixed plate provided on the other side of the rotating seat further enhances the stability of the overall structure, ensuring that the brake line can remain stable when transmitting braking force. The presence of the fixed plate also simplifies the installation process of the brake line, improves the installation accuracy, and makes the entire brake system more efficient and safe.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0032] The following describes an embodiment of the utility model based on its overall structure.

[0033] Embodiment 1:

[0034] A brake line connection mechanism, such as Figure 1-Figure 4 As shown, it includes a side plate 1, a rotating arm 2 and a brake line 4. The rotating arm 2 is connected to the brake line 4 through a connecting mechanism 3. The connecting mechanism 3 includes a rotating seat 301. A movable plate 303 and a pressure plate 306 are arranged inside the rotating seat 301. A support rod 304 is arranged between the movable plate 303 and the pressure plate 306. A limit rod 305 is arranged on one side of the movable plate 303. A pressure spring 309 is arranged on the other side of the movable plate 303. A slot 302 is opened on the rotating seat 301. As the pressure gradually increases, the pressure plate 306, the support rod 304, and the pressure plate 306 are arranged on the rotating seat 301. The support rod 304 and the movable plate 303 will overcome the elastic force of the pressure spring 309 and move, so that the limit rod 305 is displaced to one side. In this way, the brake line 4 can be easily detached from the rotating seat 301 from the open side of the slot 302, thereby eliminating the complicated operation of removing the adjusting nut 8 at the end of the brake line 4. At the same time, this arrangement significantly improves the convenience of installation and disassembly of the brake line 4. During installation, only simple operation is required to quickly fix the brake line 4 on the rotating seat 301, which greatly improves work efficiency and facilitates subsequent maintenance and replacement work.

[0035] See also Figure 1 , Figure 2The rotating seat 301 passes through the rotating arm 2 through the through hole, and the brake line 4 is rotatably connected to the rotating arm 2 through the rotating seat 301, so that the brake line 4 can be firmly connected to the rotating arm 2 through this structure. This connection method not only ensures the stability of the brake line 4 when transmitting braking force, but also ensures that the rotational force can be effectively transmitted from the brake line 4 to the rotating arm 2. At the same time, the brake line 4 is rotatably connected to the rotating arm 2 through the rotating seat 301, which increases the flexibility and reliability of the entire braking system. This connection method allows the brake line 4 to smoothly drive the rotating arm 2 to rotate when it is pulled, thereby realizing a fast and effective braking operation.

[0036] See also Figure 3 , Figure 4 The limit rod 305 is used to limit the position of the brake line 4. The end of the brake line 4 is threadedly connected with an adjusting nut 8, which ensures that the brake line always remains stable during use and will not shift due to external factors or braking operations, thereby improving the accuracy and reliability of braking. At the same time, the end of the brake line 4 is threadedly connected with an adjusting nut 8, so that the tension of the brake line 4 can be finely adjusted as needed. By rotating the adjusting nut 8, the tightness of the brake line 4 can be changed to adapt to different braking needs and riding conditions. This adjustability not only improves the flexibility of braking, but also makes the braking system more adaptable to various complex environments and the personalized needs of riders.

[0037] See also Figure 3 , Figure 4 The pressure spring 309 is used to provide a rebound support force for the limit rod 305. The other end of the pressure spring 309 abuts against the inner wall of the rotating seat 301, ensuring that the limit rod 305 can quickly and accurately return to the initial position after being subjected to external force. This helps to maintain the stability and reliability of the brake line 4 and prevent it from shifting due to external interference. At the same time, the other end of the pressure spring 309 abuts against the inner wall of the rotating seat 301. This connection method enhances the stability of the entire mechanism. The abutment setting enables the elastic force of the pressure spring 309 to be evenly transmitted to the rotating seat 301, reducing energy loss and improving the response speed and efficiency of the brake system.

[0038] See also Figure 3 , Figure 4 One side of the slot 302 is an open structure for installing the brake line 4, which greatly facilitates the installation of the brake line 4. The open structure allows the brake line 4 to be easily inserted into the slot 302 from the opening, simplifies the installation steps, and improves work efficiency. At the same time, this structure also increases the flexibility of installation. Whether installing the brake line 4 on a new car or reinstalling it during maintenance or replacement, the setting of the opening structure makes the operation more convenient and quick, reduces the difficulties and challenges in the installation process, and improves the user experience.

[0039] Embodiment 2:

[0040] See also Figure 2 , Figure 3 , Figure 4 A limiting cover 307 is detachably connected to one side of the rotating seat 301, which is used to limit the position of the pressure plate 306 and the movable plate 303. A fixing plate 308 is provided on the other side of the rotating seat 301. The limiting cover 307 can effectively limit the position of the pressure plate 306 and the movable plate 303, ensuring that these components remain stable during operation and will not accidentally move or misalign. At the same time, the fixing plate 308 provided on the other side of the rotating seat 301 further enhances the stability of the structure. The fixing plate 308 not only provides additional support for the rotating seat 301, but also ensures the precise alignment and positioning of the brake line 4 and other related components.

[0041] See also Figure 2 , Figure 3 , Figure 4 An opening 310 is provided at the central axis of the limit cover 307, for an external rod-shaped tool to pass through the opening 310 to apply a pressing force to the pressure plate 306. The opening 310 provides a convenient access point for external rod-shaped tools, which enables maintenance personnel to easily use tools to pass through the opening 310 and directly apply a pressing force to the pressure plate 306. At the same time, the installation and removal process of the brake line 4 is simplified. Through the opening 310, the movement of the pressure plate 306 and the movable plate 303 can be more easily controlled, thereby conveniently installing or removing the brake line 4, which not only improves the maintenance efficiency, but also reduces the complexity of the operation, providing users with a better user experience.

[0042] See also Figure 1 A fixing plate 5 is provided on one side of the surface of the side plate 1, and the brake line 4 is engaged with the fixing plate 5, providing a stable engaging point for the brake line 4, which enables the brake line 4 to be firmly engaged with the fixing plate 5, ensuring that the brake line will not shake or fall off during riding and use, and provides a certain installation support force for the brake line 4. At the same time, the installation process of the brake line 4 is simplified and the installation efficiency is improved. The engaging connection between the brake line 4 and the fixing plate 5 also makes subsequent maintenance and adjustment more convenient and quick. In addition, the stable engagement can also ensure that the brake line 4 will not slip when transmitting the braking force, thereby ensuring the accuracy and reliability of the brake, and providing an important guarantee for riding safety.

[0043] See also Figure 1A tensioning spring 6 is arranged on the outside of the brake line 4, and the side plate 1 is connected to the frame through the mounting shaft 7. The tensioning spring 6 can always keep the brake line in a tensioned state, which ensures that the brake line 4 will not affect the braking effect due to relaxation when transmitting the braking force, thereby improving the sensitivity and reliability of the brake. At the same time, the side plate 1 is connected to the frame through the mounting shaft 7. This connection method is both stable and flexible, which enables the side plate 1 to be firmly fixed to the frame, thereby ensuring the stability of the brake system.

[0044] The implementation principle of the utility model is as follows: when the brake line 4 needs to be removed, first, a rod-shaped tool, such as a cross pick, is used to penetrate the opening 310 to press the pressure plate 306. As the pressure gradually increases, the pressure plate 306, the support rod 304 and the movable plate 303 overcome the elastic force of the pressure spring 309 to move their positions until the limiting rod 305 is moved to one side. Subsequently, the brake line 4 can be separated from the rotating seat 301 from the opening side of the slot 302, eliminating the need for adjusting the end of the brake line 4. During the removal operation of the joint nut 8, when the brake line 4 needs to be installed and connected to the rotating seat 301, the pressure plate 306 is pressed to open the opening side of the slot 302, and then the brake line 4 is placed into the interior of the slot 302. Then, the pressure on the pressure plate 306 is released, and the elastic force of the pressure spring 309 is used to cause the limit rod 305 to return to its initial position. The limit rod 305 is used to limit the brake line 4 to complete the installation of the brake line 4, thereby improving the convenience of installation and disassembly of the brake line 4.
