[0019] Embodiment

[0020] Please refer to Figs. 1-3 The utility model discloses an electric bicycle frame mounting mechanism, including the base 1, the base 1 top is provided with the mounting frame 2, is provided with the sliding slot on the lateral wall of mounting frame 2, the lifting block 4 of sliding setting is provided on the sliding slot, the base 1 top still is provided with electric push rod 3, and the telescopic arm end of electric push rod 3 top is connected with the lifting block 4, at this time under the action of electric push rod 3, can drive the lifting block 4 and move up and down, and then the subsequent operation of using the device is convenient accordingly.

[0021] The sliding block 5 is slidably arranged inside the lifting block 4, and the threaded rod 7 is rotatably arranged inside the lifting block 4. The threaded rod 7 penetrates the sliding block 5 and is threadedly connected with the sliding block 5. At this time, rotating the threaded rod 7 can drive the sliding block 5 to move. The bottom of the sliding block 5 is further provided with a rack 6. The mounting shaft 8 is rotatably arranged on the lifting block 4. The gear 9 is arranged on the mounting shaft 8 inside the lifting block 4 through a key connection. The gear 9 and the rack 6 are intermeshed. At this time, rotating the threaded rod 7 can drive the rack 6 to move through the sliding block 5, so that the rack 6 drives the gear 9 to rotate, and then drives the mounting shaft 8 to rotate. The side wall of the lifting block 4 is further provided with a self-locking mechanism cooperating with the threaded rod 7. At this time, under the action of the self-locking mechanism, the threaded rod 7 can be fixed, so that the angle of the mounting shaft 8 after rotating can be limited, thereby ensuring the use efficiency of the subsequent mounting shaft 8. The outer end of the threaded rod 7 is provided with a first handle 701. Rotating the first handle 701 can drive the threaded rod 7 to rotate, thereby better adjusting the angle of the mounting shaft 8.

[0022] The outer end of the mounting shaft 8 is provided with a mounting shell 10, and the mounting shell 10 is provided with two sliding plates 11 slidingly arranged thereon. The side wall of the sliding plate 11 is provided with a clamping block 12. At this time, the bicycle frame can be clamped and fixed under the action of the clamping block 12, thereby facilitating the subsequent workers to set the related components such as the wheels on the frame. The inside of the mounting shell 10 is also provided with a bidirectional screw rod 13 rotatingly arranged therein. The bidirectional screw rod 13 penetrates through and is in threaded connection with the two sliding plates 11. At this time, rotating the bidirectional screw rod 13 can drive the two sliding plates 11 to move close to or away from each other. The mounting shell 10 is also provided with a worm 15 rotatingly arranged thereon. The bidirectional screw rod 13 is also provided with a worm wheel 14 connected thereto through a key. The worm wheel 14 is in meshing connection with the worm 15. At this time, rotating the worm 15 can drive the bidirectional screw rod 13 to rotate through the worm wheel 14, so that the clamping block 12 can clamp and fix the frame. In addition, the worm wheel 14 and the worm 15 have a self-locking function, so that the position of the clamping block 12 after adjustment can be limited, thereby ensuring the clamping and fixing quality of the clamping block 12 on the frame. The outer end of the worm 15 is provided with a second rotating handle 1501. Rotating the second rotating handle 1501 can drive the worm 15 to rotate.

[0023] In actual use, the up-down position of the lifting block 4 on the sliding groove can be adjusted through the telescopic function of the electric push rod 3 to adapt to the installation requirements of frames of different heights. When the lifting block 4 reaches the required height, the electric push rod 3 is used to keep it stable by using the self-locking function of the electric push rod 3. The threaded rod 7 is driven to rotate in the lifting block 4 by rotating the first rotating handle 701. Since the threaded rod 7 is in threaded connection with the sliding block 5, the rotation of the threaded rod 7 will push the sliding block 5 to slide in the lifting block 4. The rack 6 at the bottom of the sliding block 5 will mesh with the gear 9 as the sliding block 5 moves, thereby driving the mounting shaft 8 to rotate on the mounting block 4. This step realizes the accurate adjustment of the angle of the mounting shaft 8 to meet the specific angle requirements of frame installation. The mounting shell 10 at the outer end of the mounting shaft 8 is provided with two sliding plates 11. The two sliding plates 11 are adjusted to move close to or away from each other by rotating the bidirectional screw rod 13. When the second rotating handle 1501 is rotated, the worm 15 is rotated and drives the bidirectional screw rod 13 to rotate through the meshing with the worm wheel 14. Since the bidirectional screw rod 13 is in threaded connection with the two sliding plates 11, the rotation of the bidirectional screw rod 13 will push or pull the sliding plates 11 to move close to or away from each other, thereby adjusting the distance between the clamping blocks 12. This step realizes the clamping and fixing of the frame. During the clamping and fixing of the frame by the clamping blocks 12, the self-locking function of the worm wheel 14 and the worm 15 ensures the stability of the position of the clamping blocks 12 after adjustment, thereby avoiding the loosening of the clamping caused by vibration or external force interference.
