Description

Technical Field

[0001] This utility model relates to the field of bicycle repair technology, specifically to a lifting platform for repairing bicycles. Background Technology

[0002] Bicycles are one of the most commonly used means of transportation. After prolonged use, some parts will inevitably break down. To facilitate repairs, repair personnel need to suspend the bicycle to a suitable position for operation, thereby increasing repair efficiency. Currently, the common repair methods are to repair the bicycle upside down or to suspend it using a fixed repair rack. However, since the height of traditional repair racks is not easily adjustable and the position may be fixed, repair personnel of different heights will inevitably experience discomfort and inconvenience when using the same repair rack, which cannot meet the needs of users.

[0004] Preferably, the rotation drive assembly includes a rotating inner rod disposed within a fixed shaft. One end of the rotating inner rod is rotatably connected to the inner wall of the fixed shaft via a bearing, and the other end is connected to a rotating shaft. A worm gear is disposed at the connection between the rotating inner rod and the rotating shaft. A worm is meshed on the upper part of the worm gear. The worm is perpendicular to the rotating inner rod, extends to one side of the fixed shaft, and is connected to a drive gear assembly.

[0005] Preferably, the drive gear assembly includes a large gear disposed at the end of the worm, a small gear meshing with the bottom of the large gear, the large gear and the small gear being disposed inside a gear cover, and a rotating handle for rotating the small gear being disposed outside the gear cover.

[0006] Preferably, the worm gear is provided with a worm gear cover that communicates with the fixed shaft.

[0007] Preferably, the drive motor is provided with a motor cover and a power connection cable extending out of the motor cover.

[0008] The advantages of this utility model compared with the prior art are as follows: This utility model can realize the lifting and lowering from the moment the bicycle touches the ground by setting up a multi-stage lifting column, which makes it convenient to adjust the height; the clamp is rotated by rotating the handle to drive the worm gear to rotate the clamp, which is easy to operate and can be quickly mastered by operators, reducing labor costs and saving time, space and labor costs.

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0014] In the description of the embodiments of this utility model, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and "third" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0015] Furthermore, the use of terms such as "horizontal," "vertical," and "sag" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0016] In the description of the embodiments of this utility model, "a plurality of" means at least two.

[0017] In the description of the embodiments of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] Example:

[0019] Combined with appendix Figure 1-4 A lifting platform for repairing bicycles includes a base 1. A multi-stage lifting column 2 and a drive motor for driving the multi-stage lifting column 2 are arranged on the upper part of the base 1. The drive motor is provided with a motor cover 8 and a power connection cable 9 extending out of the motor cover 8. A bicycle bearing shaft 4 is connected to the multi-stage lifting column 2 through a fixing frame 3. The bicycle bearing shaft 4 includes a fixed shaft 401 connected to the fixing frame 3 and a rotating shaft 402 rotatably connected to the fixed shaft 401. A bicycle clamping claw 5 is provided at the end of the rotating shaft 402 away from the fixed shaft 401. A rotation drive assembly 6 is provided at the connection between the fixed shaft 401 and the rotating shaft 402.

[0020] The rotation drive assembly 6 includes a rotating inner rod 601 disposed within a fixed shaft 401. One end of the rotating inner rod 601 is rotatably connected to the inner wall of the fixed shaft 401 via a bearing 602, and the other end is connected to a rotating shaft 402. A worm gear 603 is disposed at the connection between the rotating inner rod 601 and the rotating shaft 402. A worm 604 is meshed on the upper part of the worm gear 603. The worm 604 is perpendicular to the rotating inner rod 601, extends to one side of the fixed shaft 401, and is connected to a drive gear assembly 7. The drive gear assembly 7 includes a large gear 701 disposed at the end of the worm 604. A small gear 702 is meshed at the bottom of the large gear 701. The large gear 701 and the small gear 702 are disposed within a gear cover 704. A rotating handle 703 for rotating the small gear 702 is disposed outside the gear cover 704. A worm cover 605 communicating with the fixed shaft 401 is disposed outside the worm 604.

[0021] In this embodiment, the multi-stage lifting column can be an electric lifting rod or a screw lifting rod, which has at least two lifting stages. During maintenance, the bicycle is fixed by the bicycle clamp, and then the rotating handle is turned, which drives the small gear to rotate. This, in turn, drives the worm gear through the large gear and worm, thereby rotating the rotating shaft connected to the bicycle, thus rotating the bicycle and facilitating maintenance. The small gear can also be connected to an external electric rotating device. For example, the small gear can be rotated electrically through an external rotating motor and reducer output shaft, making it more labor-saving.
