Description

Bicycle goods shelf with barrel shaft Technical Field The utility model 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 utility model The object of the present utility model is to solve the above mentioned problems in the prior art and to provide a bicycle rack with a tub shaft. The utility model adopts the following technical scheme for realizing the purposes: The bicycle goods shelf with the barrel shaft comprises a carrying plate, two support brackets which are buckled below the carrying plate, two symmetrically arranged connecting mechanisms which are arranged at the head end and the tail end of the support brackets, wherein each connecting mechanism comprises a connecting plate, goods shelf fork feet are detachably arranged on the outer sides of the connecting plates through fixing shafts, connecting shafts are arranged at the lower ends of the goods shelf fork feet, and a protective frame is arranged on the outer sides of the support brackets. Further, the lower ends of both sides of the carrying plate are provided with buckling grooves, the upper ends of the supporting brackets are buckled in the buckling grooves, and the upper ends of the carrying plate are provided with four symmetrically arranged through grooves. Further, the goods shelf fork foot with the through-hole that the concentric circles set up has been seted up to the inside of connecting plate, just the inside through-hole of goods shelf fork foot is provided with a plurality ofly along the vertical direction is even, the fixed axle runs through the through-hole setting.
