Description

Bicycle goods shelf with barrel shaft Technical Field The invention relates to the technical field of bicycle shelves, in particular to a bicycle shelf with a barrel shaft. Background In recent decades, the field of sports bicycles has experienced unprecedented rapid developments, and the design and construction of bicycles have undergone significant changes that present new challenges to the compatibility and functionality of bicycle accessories. Particularly in the field of bicycle shelves, the existing shelf products on the market are generally difficult to adapt to the current sports bicycles. First, from the standpoint of material application, early bicycle frames were made primarily of aluminum alloys, which benefited from good workability and relatively low cost, and manufacturers were able to easily open mounting holes in the frame to accommodate various types of racks. However, with the gradual decrease of the cost of carbon fiber materials and the remarkable light weight and high strength characteristics thereof, the modern sports bicycle frames have widely adopted carbon fiber materials. Although the carbon fiber frame has excellent performance, the unique material property makes it very difficult to reserve the shelf mounting hole site on the frame, and the slim structure of the carbon fiber tube is difficult to bear the weight pressure caused by the traditional shelf loading, thereby limiting the possibility of mounting the shelf on the carbon fiber frame. Second, the evolution of bicycle types also presents new problems. In recent years, soft-tailed mountain bikes have been popular due to their excellent shock absorbing performance and handleability. The frame of the bicycle adopts a soft connection design with a shock-absorbing structure, is fundamentally incompatible with the hard connection mode of the fixed rear wheel end and the frame end adopted by the traditional goods shelves on the market, and leads to the fact that the traditional goods shelves cannot be effectively arranged on the soft tail bicycle. Furthermore, the wheel diameter and the tire width of the mountain bike are also obviously increased, the traditional 26-inch wheel diameter is gradually changed into 27.5-inch wheel diameter or even the current 29-inch wheel diameter, and the situation that three wheel diameters coexist is formed on the market. This variation directly affects the mounting adaptability of the pallet, because the conventional pallet design does not take into account the variety of wheel diameters, and thus it is difficult to achieve a stable and proper mounting on bicycles of different wheel diameters. In summary, due to the combined actions of material innovation, frame design change and wheel diameter diversity, the conventional bicycle rack cannot meet the installation requirements of modern sport bicycles. In this context, it is important and urgent to develop a bicycle rack that overcomes the above-mentioned problems and is compatible with many modern sport bicycle types, and for this purpose, we propose a bicycle rack with a tub shaft. Disclosure of Invention The object of the present invention is to solve the above mentioned problems in the prior art and to provide a bicycle rack with a tub shaft. The invention adopts the following technical scheme for realizing the purposes: The bicycle rack with the barrel shaft comprises a rack main body, rack fork feet are detachably mounted at the lower ends of two sides of the rack main body, two rack arms which are symmetrically arranged are movably mounted on the right side of the rack main body, rack handles are detachably mounted on the right side of each rack arm, a barrel shaft lever is detachably mounted between the two rack fork feet, locking screws are mounted at two ends of the barrel shaft lever, and the locking screws are located on the outer sides of the rack fork feet. Further, the shelf main body is made of high-strength aluminum. Further, locating frames are arranged on the left side and the right side of the goods shelf main body, and limiting plates are arranged between the two locating frames. Further, the inside of goods shelves arm left side with the spacing groove has all been seted up to the inside of limiting plate, and the internally mounted in spacing groove has stop bolt. Further, a supporting bracket is arranged on the outer side of the positioning frame. Further, the connecting plates are arranged at the lower ends of the two sides of the goods shelf main body. Further, the inside of connecting plate with the screw hole that the internal diameter is unanimous is offered to the inside of goods shelves fork foot, and the inside of screw hole is through screw thread demountable installation has fixing bolt. Further, two symmetrically arranged rear upper fork grippers are arranged on the left side of the goods shelf main body. Further, screw holes which are arranged in concentric circles are formed in the goods shelf fork feet and the
