This bicycle front fork locks the connecting shaft and thus locks the wheel, thereby playing an anti-theft role. That is to say, the wheel of the bicycle is fixed to the axle, and the axle can rotate relative to the front fork. However, the front axle of most bicycles on the market is fixed to the front fork, and the wheel rotates relative to the front axle. Therefore, the bicycle front fork is less compatible with bicycles with fixed front axles and front forks. Utility Model Content
[0003] In order to solve the above technical problems, the utility model provides a bicycle front fork with an anti-theft lock, which locks the brake disc of the front axle and improves the compatibility with the bicycle with the front axle and the front fork fixed.
[0004] The utility model is realized by the following technical solutions:
[0005] A bicycle front fork with an anti-theft lock comprises a fork shoulder, inner tubes are respectively installed on the left and right sides of the lower part of the fork shoulder, an outer tube is sealingly and slidably provided at the lower end of each inner tube, a fork bridge is integrated at the front between the two outer tubes, a grab hook is integrated at one side of the lower end of each outer tube, a front axle is fixedly installed between the two grab hooks, and the invention is characterized in that an anti-theft lock body assembly is installed on the outside of one of the outer tubes, the anti-theft lock body assembly comprises a mounting seat and a fixing seat fixedly installed on the outside of the same outer tube, a lock body is detachably installed on a side of the mounting seat away from the outer tube, and a lock rod is installed inside the fixing seat through a fixing bolt.
[0006] Preferably, the middle bearing of the front axle is mounted with a wheel center mounting seat, one end of the wheel center mounting seat is fixedly mounted with a brake disc, and the front axle passes through the brake disc.
[0007] Preferably, the lock body and the fixing seat are arranged on both sides of the brake disc.
[0008] Compared with the prior art, the beneficial effects of the utility model are:
[0009] In the utility model, the arrangement of the mounting seat, the fixing seat, the lock body, the locking rod and the fixing bolts locks the brake disc of the front axle, thereby improving the adaptability to the bicycle with the front axle and the front fork fixed.
[0010] In the utility model, the arrangement of the grab hook is conducive to fixing the front axle. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] 1. Fork crown; 2. Head tube; 3. Inner tube; 4. Outer tube; 5. Fork bridge; 6. Grab hook; 7. Front axle; 8. Anti-theft lock body assembly; 9. Wheel center mounting seat; 10. Brake disc; 81. Mounting seat; 82. Fixing seat; 83. Lock body; 84. Lock rod; 85. Fixing bolt. DETAILED DESCRIPTION
[0015] The utility model is described in detail below in conjunction with the accompanying drawings. Figure 1 As shown, a bicycle front fork with an anti-theft lock comprises a fork shoulder 1, a head tube 2 is integratedly arranged at the middle part of the upper side of the fork shoulder 1, inner tubes 3 are respectively installed on the left and right sides of the lower part of the fork shoulder 1, an outer tube 4 is sealed and slidably arranged at the lower end of each of the inner tubes 3, a fork bridge 5 is integratedly arranged at the front part between the two outer tubes 4, a grab hook 6 is integratedly arranged on one side of the lower end of each of the outer tubes 4, a front axle 7 is fixedly installed between the two grab hooks 6, and an anti-theft lock body assembly 8 is installed on the outside of one of the outer tubes 4.
[0016] In this embodiment, combined with the Figure 2 As shown, the anti-theft lock body assembly 8 includes a mounting seat 81 and a fixing seat 82 fixedly mounted on the outside of the same outer tube 4. A through hole for inserting a lock rod 84 is provided inside the fixing seat 82. A lock body 83 is detachably installed on the side of the mounting seat 81 away from the outer tube 4. A lock rod 84 is installed inside the fixing seat 82 through a fixing bolt 85. The inside of the lock rod 84 has mounting holes for installing the fixing bolt 85 arranged side by side. The lock rod 84 is adapted to the lock body 83. When locking the car, the fixing bolt 85 is loosened so that the lock rod 84 is locked. One end of 84 is inserted into the lock body 83, and the lock body 83 locks one end of the locking rod 84. At this time, the locking rod 84 passes through the brake disc 10 to fix the brake disc 10. Since the brake disc 10 is fixed to the wheel center mounting seat 9, it can fix the wheel without passing through the wheel spokes, thereby realizing the anti-theft function. When unlocking, the lock body 83 is opened using a key adapted to the lock body 83, the locking rod 84 is pulled out, and the fixing bolt 85 is rotated to fix the locking rod 84 to the fixing seat 82, thereby fixing the locking rod 84.
[0017] In the present embodiment, specifically, the middle bearing of the front axle 7 is installed with a wheel center mounting seat 9, one end of the wheel center mounting seat 9 is fixedly installed with a brake disc 10, the front axle 7 passes through the brake disc 10, and the outer tube 4 of the anti-theft lock body assembly 8 is installed close to the brake disc 10.
[0018] In this embodiment, specifically, the lock body 83 and the fixing seat 82 are arranged on both sides of the brake disc 10 .
[0019] In this embodiment, specifically, the height of the locking rod 84 matches the height of the insertion holes provided around the brake disc 10 .
[0020] How it works
[0021] In the utility model, the head tube 2 is used to install the frame and the handlebars, the front axle 7 is used to install the wheel center mounting seat 9, and during shock absorption, the inner tube 3 moves relative to the outer tube 4 to play a role in buffering and shock absorption, and the anti-theft lock body assembly 8 fixes the brake disc 10 to play an anti-theft role.
[0022] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
