[0020] The embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0021] like Figures 1 to 6 The figure shows a schematic diagram of the structure of the utility model, in which the figure marks are: crank 1, pedal body 2, locking screw 3, quick-release spindle 4, quick-release latch 5, quick-release latch through hole 6, crank assembly hole 7, shaft head groove 8, latch groove 9.

[0022] like Figures 1 to 6 As shown, a quick-installation anti-loosening mechanism for a fitness bike pedal comprises a crank 1 and a pedal body 2. A crank assembly hole 7 is formed at the assembly end of the crank 1. The pedal body 2 is equipped with a quick-installation spindle 4 for passing through the crank assembly hole 7. The quick-installation spindle 4 and the crank assembly hole 7 are in a slot structure and cooperate with each other to form a quick-installation anti-loosening mechanism.

[0023] The shaft head of the quick-install core shaft 4 has a shaft head groove 8 which is in the shape of a square as a whole, and the corresponding crank assembly hole 7 is provided with an inner convex structure which matches the shaft head groove 8. The shaft head groove 8 has a tapered structure which is contracted from top to bottom.

[0024] A quick-release latch through hole 6 is formed on the side wall of the crank 1 above the crank assembly hole 7. The quick-release latch through hole 6 is provided with a quick-release latch 5 inserted therein. A latch groove 9 with a certain taper is formed on one side of the quick-release latch 5. The latch groove 9 is adapted to fit with the shaft head groove 8 of the quick-release mandrel 4. A screw assembly hole is formed at the center of the end face of the quick-release latch 5, and a locking screw 3 is provided. The thread of the locking screw 3 is interchangeably connected with the thread of the screw assembly hole of the quick-release latch 5. The locking screw 3 is inserted into the screw assembly hole, and the locking screw 3 is screwed until the quick-release latch 5 is pulled from the side of the quick-release latch through hole 6 to the matching position of the shaft head groove 8, and then the quick-release mandrel 4 is locked and fixed. After the quick-release spindle 4 is placed in the crank assembly hole 7 on the crank 1, the locking screw 3 is pulled to pull the quick-release pin 5 from the outer edge of the quick-release pin through-hole 6 to the center of the hole, and then the locking screw 3 is installed and fixed.
