Description

Technical Field

[0001] This utility model relates to the field of bicycle storage technology, and in particular to a safety rack for storing folding bicycles. Background Technology

[0002] With the acceleration of urbanization and the improvement of people's environmental awareness, folding bicycles have become a popular choice for short-distance travel due to their portability and flexibility. However, the problem of storing folding bicycles when not in use is becoming increasingly prominent. Whether at home, in the office or in public spaces, there is a need for an efficient and safe storage method to save space and prevent damage to the bicycle.

[0003] Most existing folding bicycle storage racks on the market, especially the no-drill floor-standing type, have a fixed height, making them unsuitable for flexible adjustment based on the size of the folding bicycle and the height of the storage space. This results in poor applicability. For different bicycle models and folding levels, fixed-height racks may struggle to provide stable suspension, potentially causing the bicycle to wobble or fall due to unsuitable height, posing a safety hazard. Furthermore, the angle adjustment of the rack typically uses locking nuts, which is inconvenient and imprecise. During suspension, it's difficult to adjust the bicycle to the most space-saving or stable angle, affecting storage efficiency. Therefore, improvements are needed to address these issues.

[0007] Preferably, the fixed cylinder has multiple fixed through holes equidistantly opened along the T-shaped guide groove, and the T-shaped block has an installation groove on the opposite surface of the fixed through holes. A locking block is movably installed in the installation groove. The shape of the locking block corresponds to the fixed through holes. A spring is fixedly connected to one end of the locking block, and one end of the spring is fixedly connected to the inner wall of the installation groove.

[0008] Preferably, the top of the inner wall of the fixed cylinder is provided with an internal thread, and an external thread cylinder is screwed onto the internal thread. A limiting decorative cover is fixedly connected to the top of the external thread cylinder, the bottom surface of the limiting decorative cover abuts against the top of the fixed cylinder, and the limiting decorative cover is sleeved on the sleeve.

[0009] Preferably, the connecting rod and the connecting cylinder are coaxially provided with a threaded through hole in the middle, a fixing bolt is inserted in the threaded through hole, the bottom end of the connecting rod is provided with a hexagonal groove, and the bottom surface of the connecting cylinder is provided with a hexagonal protrusion corresponding to the shape of the hexagonal groove.

Furthermore, through the cooperation of a worm gear and a worm, rotating the knob drives the worm to rotate, and the worm drives the worm gear and rotating rod to rotate, realizing the angle adjustment of the hanging arm bracket. There is no need to tighten the locking nut, which facilitates precise angle adjustment and improves the convenience and accuracy of adjustment, thus enabling the bicycle to be adjusted to the most space-saving or most stable angle. Finally, it solves the problems of fixed height and inconvenient angle adjustment of existing drill-free floor-standing hanging brackets, improving the safety and efficiency of storage.
