Description

Technical Field

[0001] This utility model relates to the field of bicycle parts technology, specifically to an anti-detachment bicycle front fork. Background Technology

[0002] The bicycle fork is a key component of the bicycle structure. Located at the front of the bicycle, it connects the frame and the front wheel. Its main functions include supporting the front wheel, controlling steering, absorbing shocks, and improving riding comfort. The design and material selection of the fork are crucial to the overall performance of the bicycle and the riding experience.

[0003] A traditional bicycle fork consists of a vertical tube and two foot tubes, which are connected to the two sides of the vertical tube respectively. During installation, the sleeve in the middle of the front of the bicycle is placed on the vertical tube. After the sleeve is put on, the sleeve is tightened with screws, thereby achieving relative fixation between the vertical tube and the front of the bicycle.

[0004] A traditional bicycle fork consists of a vertical tube and two foot tubes, which are connected to both sides of the vertical tube. The foot tubes are equipped with fork legs. During installation, the vertical tube is connected to the handlebars and the frame, and the fork legs are connected to the connecting axle of the wheel assembly. The fork legs are then tightened using a wrench.

[0005] However, during the installation of a bicycle front fork, the connection between the fork legs and the wheelset is exposed, making it susceptible to loosening due to impacts from external forces such as flying stones during riding, which can cause the front fork to easily detach from the wheelset.

[0006] Based on this, this utility model designs an anti-detachment bicycle front fork to solve the above problems. Utility Model Content

[0007] To achieve the above objectives, the present invention provides the following technical solution: a fixing post is fixedly provided on the foot fork, a clearance groove is provided on the fixing post, a protective cover is rotatably provided in the clearance groove, a limit block is fixedly provided on the foot fork, and when the side of the protective cover abuts against the limit block, the protective cover is fastened to the foot fork.

[0008] By adopting the above technical solution, after the fork and wheelset are installed, the protective cover is rotated so that it can rotate along the fixed post until it covers the fork. At this time, the connection between the fork and the wheelset is completely covered by the protective cover. When riding, the protective cover can protect the fork, reduce the impact of external forces on the fork, prevent the connection between the fork and the wheelset from loosening, and improve the fork's anti-disengagement performance.

[0009] Preferably, one end of the foot fork is provided with a sliding cavity, a baffle is slidably disposed in the sliding cavity, a guide groove is provided on the sliding cavity, a push-pull block is slidably disposed in the guide groove, the push-pull block is fixedly connected to the baffle, and when the push-pull block slides to the bottom of the guide groove, the baffle extends from the sliding cavity to the other end of the foot fork.

[0010] By adopting the above technical solution, the interactive push-pull block allows the baffle to slide out of the sliding cavity and extend from one end of the fork until it reaches the other end of the fork, so that the opening of the fork is covered by the baffle, thus closing the opening on the fork. The connecting shaft on the wheel set is limited in the opening of the fork, which can further increase the tightness of the connection between the fork and the wheel set, so that the fork will not easily detach from the connection with the vehicle body, thereby enhancing the safety of the fork.

[0011] Preferably, the limiting block is equipped with a magnetic block, and the protective cover is made of metal material.

[0012] By adopting the above technical solution, the connection between the limiting block and the protective cover is increased, making the closing of the protective cover more stable.

[0013] Preferably, a retaining block is provided on one side of the protective cover, and when the protective cover is closed on the foot fork, the retaining block abuts against the push-pull block.

[0014] By adopting the above technical solution, when the protective cover covers the foot fork, the push-pull block is less likely to slip, allowing the baffle to play a more stable limiting role.

[0015] Preferably, a cushioning gasket is provided at the bottom of the protective cover.

[0016] By adopting the above technical solution, the buffer gasket can absorb part of the external force when the protective cover is impacted, thus increasing the protective performance of the protective cover.

[0017] Preferably, the upper surface of the protective cover is provided with anti-slip protrusions.

[0018] By adopting the above technical solution, the rotation of the protective cover becomes easier and more convenient.

[0019] In summary, this application has the following beneficial technical effects: By adopting the above technical solution, after the fork and wheelset are installed, the protective cover is rotated so that the protective cover can rotate along the fixed post until the protective cover covers the fork. At this time, the connection between the fork and the wheelset is completely covered by the protective cover. When riding, the protective cover can protect the fork, reduce the impact of external forces on the fork, prevent the connection between the fork and the wheelset from loosening, and improve the fork's anti-disengagement performance.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0028] A type of anti-detachment bicycle fork includes a vertical tube 1 and a foot tube 2. The foot tube 2 is fixedly connected to both sides of the vertical tube 1. A foot fork 3 is fixedly mounted on the foot tube 2. The foot fork 3 has an opening. A connecting shaft is mounted on the wheel assembly. The connecting shaft is locked to the opening of the foot fork 3. A fixing post 5 is fixedly mounted on the foot tube 2. A clearance groove is opened on the fixing post 5. A protective cover 7 is rotatably mounted on the clearance groove. A limit block 6 is fixedly mounted on the foot fork 3.

[0029] When in use, push the protective cover 7 so that it begins to rotate along the fixed post 5 until the side of the protective cover 7 abuts against the limiting block 6. At this time, the protective cover 7 covers the connection between the fork 3 and the wheel set. When subjected to an impact from an external force, the protective cover 7 can protect the connection, reduce the impact on the connection, prevent the connection between the fork 3 and the wheel set from loosening and falling off, and enhance the stability of the bicycle.

[0030] A sliding cavity is provided on one side of the opening of the foot fork 3. An outlet is provided on the sliding cavity. A baffle 8 is slidably arranged in the sliding cavity. A guide groove 10 is provided on the sliding cavity. A push-pull block 9 is slidably arranged in the guide groove 10. The push-pull block 9 is fixedly connected to the baffle 8. A clamping block 11 is provided on one side of the protective cover 7.

[0031] After the protective cover 7 is rotated, the clamping block 11 on the protective cover 7 also rotates. After the clamping block 11 rotates, it presses against the push-pull block 9, causing the push-pull block 9 to slide along the guide groove 10 under force. The baffle 8 in the sliding cavity begins to slide out from the outlet on the sliding cavity. When the push-pull block 9 slides to the bottom of the guide groove 10, the baffle 8 abuts against the other end of the opening, so that the opening is closed. The baffle 8 limits the connecting shaft in the opening. When the connection between the foot fork 3 and the wheel set becomes loose, the connecting shaft will not easily detach from the foot fork 3, further enhancing the anti-detachment performance of the foot fork 3.

[0032] The limiting block 6 is equipped with a magnetic block, and the protective cover 7 is made of metal. After the protective cover 7 rotates, it is attracted to the limiting block 6, so that the protective cover 7 can cover the foot fork 3 more stably, increasing the stability of the protective cover 7. The bottom of the protective cover 7 is equipped with a buffer washer 13, so that when the protective cover 7 is subjected to external impact, the buffer washer 13 can absorb part of the external force, increasing the protective performance of the protective cover 7. The upper surface of the protective cover 7 is equipped with anti-slip protrusions 12. By applying force to the anti-slip protrusions 12, the protective cover 7 will rotate, making the use of the protective cover 7 easier and less strenuous.

[0033] The implementation principle of this embodiment is as follows: When in use, push the protective cover 7 so that the protective cover 7 starts to rotate along the fixed post 5. After the protective cover 7 rotates, the abutting block 11 on the protective cover 7 also rotates. After the abutting block 11 rotates, it presses against the push-pull block 9, so that the push-pull block 9 is subjected to force and begins to slide along the guide groove 10. The baffle 8 in the sliding cavity begins to slide out from the outlet on the sliding cavity. When the push-pull block 9 slides to the bottom of the guide groove 10, the baffle 8 abuts against the other end of the opening, so that the opening is surrounded. The baffle 8 limits the connecting shaft in the opening. At this time, the side of the protective cover 7 abuts against the limiting block 6. The protective cover 7 covers the connection between the fork 3 and the wheel set. When subjected to the impact of external force, the protective cover 7 can protect the connection and reduce the impact on the connection. When the connection between the fork 3 and the wheel set becomes loose, the connecting shaft will not easily detach from the fork 3, thus enhancing the anti-detachment performance of the fork 3.
