Technical Field

[0001] This utility model relates to the field of quick-release bicycle shoulder cover technology, specifically a quick-release bicycle shoulder cover that is easy to install. Background Technology

[0002] A bicycle shoulder cover is a protective component installed on the shoulder of a bicycle frame at the junction of the front tube and top tube / down tube. It is usually made of metal or plastic. Its main function is to protect the frame junction from damage caused by collisions and scratches, while also enhancing the structural strength and stability of the frame at this location. Some aesthetically pleasing shoulder covers also serve to decorate the frame and enhance the overall visual appeal of the bike. They are commonly found on road bikes, mountain bikes, and other types of bikes. They are usually installed by screws or by an embedded design that tightly integrates with the frame.

[0003] Existing bicycle shoulder covers are mainly installed via an embedded method. While embedded installation requires no tools, it necessitates precise matching of the frame interface. Improper operation can easily lead to the shoulder cover not fitting tightly, resulting in poor convenience for embedded installation. This makes it time-consuming and laborious for users to replace the shoulder cover, deterring some users who want to personalize their bicycles. Furthermore, operational errors during installation may cause additional damage to the frame, affecting the overall performance and lifespan of the bicycle. Therefore, we propose a quick-release bicycle shoulder cover that is easy to install. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-2This utility model provides a technical solution: a quick-release bicycle shoulder cover that is easy to install, including a shoulder cover body 1. Two extension arms 2 are fixedly connected to the arc surface of the shoulder cover body 1. A fixing plate 3 is fixedly connected to the end of the extension arm 2 away from the shoulder cover body 1. A limiting structure 4 is provided on the surface of the shoulder cover body 1. The limiting structure 4 includes a bracket 401, which is fixedly connected to the surface of the shoulder cover body 1. An internally threaded tube 402 is rotatably connected to the surface of the bracket 401. Threaded rods 403 are threadedly connected to both ends of the internally threaded tube 402. A frame 404 is fixedly connected to the end of the threaded rod 403 away from the internal threaded tube 402. The fixing plate 3 is located inside the frame 404. A limiting plate 405 is fixedly connected to the inner wall of the frame 404. The size of the limiting plate 405 is adapted to the size of the fixing plate 3. By setting the limiting structure 4, the quick-release bicycle shoulder cover can be quickly clamped and released through the transmission mechanism of the internal threaded tube 402 and the threaded rod 403. This solves the problems of poor convenience and difficult disassembly of traditional embedded installation, and is suitable for scenarios that require frequent replacement or personalized modification.

[0029] Reference Figure 3 and Figure 4 and Figure 5 As shown in this embodiment: Two guide rods 406 slide through the surface of the frame 404. Both guide rods 406 are fixedly connected to the surface of the fixing plate 3. The two guide rods 406 sliding through the frame 404 are fixed to the fixing plate 3 to ensure that the frame 404 remains stable when moving and avoids deviation. Two baffles 407 are fixedly connected to the arc surface of the internally threaded tube 402. The two baffles 407 are respectively attached to both sides of the bracket 401. The baffles 407 on both sides of the internally threaded tube 402 are attached to the bracket 401 to restrict the axial movement of the internally threaded tube 402 and ensure stable clamping force. Two turntables 408 are fixedly connected to the arc surface of the internally threaded tube 402. The vertical cross section of the turntables 408 is cross-shaped. The cross-shaped turntables 408 on the internally threaded tube 402 provide a force-saving point, making it easy for the user to quickly rotate the internally threaded tube 402. Several anti-slip strips 409, made of rubber, are fixedly connected to the surface of the limiting plate 405. These rubber anti-slip strips increase friction with the bicycle fork, improving the limiting effect on the bicycle fork. A telescopic cover 410 is fitted onto the surface of the threaded rod 403. The two ends of the telescopic cover 410 are fixedly connected to the internal threaded tube 402 and the frame 404, respectively. The telescopic cover 410 on the outer side of the threaded rod 403 is connected to the internal threaded tube 402 and the frame 404, respectively. It extends or retracts when the threaded rod 403 moves, preventing dust and dirt from entering the threaded connection and avoiding thread wear that could affect clamping performance. An inclined groove 411 is provided on one side of both the limiting plate 405 and the fixing plate 3. This inclined groove 411 forms a guide slope during installation, reducing frictional resistance and allowing the bicycle fork to quickly conform to the surface of the fixing plate 3.

[0030] Working principle: When the shoulder cover body 1 needs to be connected and installed with the bicycle front fork, the shoulder cover body 1 is first aligned with the part of the bicycle front fork to be installed through the fixing plates 3 at the ends of the two side extension arms 2. The limiting plate 405 and the inclined groove 411 on one side of the fixing plate 3 form a guide slope during installation, reducing frictional resistance, so that the bicycle front fork can quickly fit against the surface of the fixing plate 3. When the bicycle front fork is fitted against the surface of the fixing plate 3, the fixing plate 3 is placed in the frame 404 of the limiting structure 4. The limiting plate 405 on the inner wall of the frame 404 is adapted to the size of the fixing plate 3 to form a preliminary positioning. The cross-shaped turntable 408 on the internal thread tube 402 provides a force-saving point, which makes it easy for the user to quickly rotate the internal thread tube 402. Rotating the turntable 408 will drive the internal thread tube 402 to rotate. The baffles 407 on both sides of the internal thread tube 402 fit against the bracket 401, restricting the axial movement of the internal thread tube 402 and ensuring stable clamping force. The internal threads at both ends of the fixed plate 402 engage with the threaded rod 403. Since the threaded rod 403 is fixedly connected to the frame 404, the rotation of the internal threaded tube 402 is converted into the linear motion of the threaded rod 403 along the axial direction. The two threaded rods 403 move synchronously towards the limiting plate 405, causing the frame 404 and the limiting plate 405 to squeeze the bicycle fork, thereby fixing the bicycle fork to the shoulder cover body 1. The telescopic cover 410 on the outside of the threaded rod 403 is connected to the internal threaded tube 402 and the frame 404 at both ends. It extends or retracts when the threaded rod 403 moves to prevent dust and mud from entering the threaded connection and avoid thread wear affecting the clamping performance. The two guide rods 406 that slide through the frame 404 are fixed to the fixing plate 3 to ensure that the frame 404 remains stable when moving and avoids deviation. The rubber anti-slip strip 409 on the surface of the limiting plate 405 increases the friction with the bicycle fork and improves the limiting effect on the bicycle fork.
