[0021] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-8 As shown, the embodiment of the utility model includes:

[0023] A bicycle mechanical mid-stop support comprises a front base 1, a rear base 2, a first pin shaft 3, a foot support 4, a second pin shaft 5, a guide pipe 6, a push rod 7, a third pin shaft 8, a rocker arm 9, a gear shaft 10, a rack 11 and an opening 12. The front base 1 and the rear base 2 are inverted on the same mounting base, the front base 1 is used to suspend the foot support 4 via the first pin shaft 3, the rear base 2 is connected to the middle section of the guide pipe 6 via the second pin shaft 5, a push rod 7 is coaxially inserted in the guide pipe 6, the head end of the push rod 7 is connected to the foot support 4 via the third pin shaft 8, a gear shaft 10 connected to the rocker arm 9 is mounted on the rear base 2, a rack 11 meshing with the gear shaft 10 is axially arranged on the outer wall of the push rod 7, and an opening 12 matching the meshing point of the rack 11 and the gear shaft 10 is arranged on the side wall of the guide pipe 6.

[0024] The gear shaft 10 is arranged in parallel on the upper side of the second pin shaft 5 .

[0025] Furthermore, the gear shaft 10 has integrally formed journals 13 extending from both ends, the rear base 2 is in an N-shape and has a pair of first mounting holes 14 matching the journals 13 , and the gear shaft 10 is mounted on the rear base 2 by connecting the journals 13 with the first mounting holes 14 .

[0026] Furthermore, a transmission slot 15 is coaxially arranged on the end face of the journal 13 , and a rocker arm 9 is coaxially inserted into the transmission slot 15 .

[0027] Furthermore, a pair of concentric grooves 16 are opened facing each other along the circumference of the outer wall of the guide tube 6, and the rear base 2 is in an N shape and has a pair of second mounting holes 17 matching the concentric grooves 16, and a second pin shaft 5 is fixed in the second mounting hole 17. The guide tube 6 is mounted on the rear base 2 by connecting the second pin shaft 5 with the second mounting hole 17.

[0028] Furthermore, the stroke length of the rack 11 is adapted to the opening and closing angle range of the foot support 4 .

[0029] Furthermore, the guide pipe 6 is divided into a guide section 18 and a control section 19. The inner tube wall of the guide section 18 is lubricated and fitted with the outer wall of the push rod 7. The inner tube wall of the control section 19 is radially divided into two halves, a guide wall 20 with a radius equal to the radius of the push rod 7 and a control wall 21 with a radius greater than the radius of the push rod 7. The lower half wall 701 of the push rod 7 is lubricated and fitted in the enclosed space formed by the guide wall 20. The other half wall 702 of the push rod 7 and the control wall 21 are mutually isolated to form a lubrication space 100. The gear shaft 10 is located in the lubrication space 100. After the guide section 18 is inserted into the telescopic push rod 7, the lubrication space 100 can be blocked, thereby preventing the grease from flowing out. The design of the lubrication space 100 can facilitate the user to perform daily maintenance on the telescopic push rod 7. The n-shaped rear base 2 covers the opening 12, which can prevent foreign matter from falling into the gear shaft 10, and plays a certain protective role.

[0030] The method of using the device is to rotate the rocker arm 9 clockwise to drive the gear shaft 10 to rotate, so that the telescopic push rod 7 in the guide pipe 6 engages and extends. As the rocker arm 9 rotates, the telescopic push rod 7 can rotate the foot support 4 in the folded state around the first pin 3 to unfold it until the foot support 4 replaces the wheel to lift the vehicle body. If parking is to be performed, the rocker arm 9 can be rotated counterclockwise to reversely drive the telescopic push rod 7 to retract. During the retraction process, the telescopic push rod 7 pulls the foot support 4 back to the folded state through the third pin 8.

[0031] In summary, the utility model provides a mechanical mid-stop support for a bicycle, which realizes manual telescopic control of the push rod 7 by hoisting the guide pipe 6 and the gear shaft 10 through the rocker arm 9 on the rear base 2. Compared with the parking method of moving the vehicle body and kicking the kickstand 4, the device utilizes the lever principle of the rocker arm 9 to achieve the goal of labor-saving parking and significantly reduce the difficulty and strength of the parking operation.

[0032] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
