Description

A new type of foldable shopping bicycle

technical field

The utility model relates to the field of bicycles, in particular to a novel foldable shopping bicycle.

Background technique

With the improvement of living standards, people's life is closely related to shopping, such as buying daily necessities in large shopping malls, and buying vegetables and fruits in vegetable markets. There are parking difficulties and road congestion when traveling by car and shopping. Bicycles have the advantages of economy, energy saving, no air pollution, and convenient use. They are suitable for short-distance travel or used in conjunction with other means of transportation. They are a "green" means of transportation that is beneficial to health and environmental protection. However, when traveling by bicycle for shopping, there is a problem that the amount of things carried is too small, and there is also a concern that the bicycle will be stolen when it is parked.

Contents of the invention

Aiming at the shortage of the existing bicycles carrying less things, the applicant hopes to design a new type of foldable shopping bicycle, which can not only be used for transportation like ordinary bicycles, but also can be folded into shopping carts in shopping malls and vegetable markets. car use.

In order to achieve the above object, the utility model adopts the following technical solutions: a novel foldable shopping bicycle, which mainly includes a faucet, a front wheel, a rear wheel, a storage box, an auxiliary small wheel, a saddle, a quick-release bolt device, a column, Cross beams, etc. The front wheel is connected with the cross beam through the faucet, the rear wheel is connected with the lower end of the column through the inclined beam, and the saddle is connected with the upper part of the column. The middle part of the column and one end of the cross beam are hinged and fixed together by a quick-release bolt device. It is characterized in that: the column first moves a short distance along the plane perpendicular to the cross-beam through the quick-release bolt device, and then it can rotate around the hinge point of the cross-beam, so that the rear wheels and front wheels are side by side. Thereby realize the conversion between bicycle and trolley.

The storage box is installed in the middle of the saddle and the rear wheel through the storage box connecting block, and two auxiliary small wheels are installed at the end of the storage box connecting block. When the bicycle is used as a normal bicycle, the two auxiliary small wheels do not work; when the bicycle is converted into a shopping cart, the front and rear wheels are side by side, and the two auxiliary small wheels touch the ground, and the front and rear wheels Form a three-wheeled shopping cart.

The utility model can be used as a tool for riding instead of walking, just like ordinary bicycles. Due to the large-capacity storage box design, the rider can carry more items. When the cyclist needs to do shopping, it can be folded into a shopping trolley, which is convenient for shopping, and at the same time, there is no need to worry about the bicycle being stolen when it is parked.

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings.

Fig. 1 is a schematic diagram of the overall structure of the bicycle in the riding state of the present invention. Riding as a regular bike is just like a regular bike. The storage box (6) is installed between the saddle (9) and the rear wheel (5) through the storage box connection block (8), which can facilitate the rider to carry more things. At this time, the auxiliary small wheel (7) is suspended behind the car and does not work.

Fig. 2 is a schematic front view of the overall structure of the folded hand-push shopping bicycle. The column (10) first moves a short distance along the plane perpendicular to the cross beam (12) through the quick release bolt device (11), and then it can rotate around the hinge point of the cross beam (12), so that the rear wheel (5) and the front wheel The wheels (2) are arranged side by side, and then the quick release bolt device (11) is adjusted to fix the positions of the column (10) and the cross beam (12). At this moment, the storage box (6) is changed from horizontal placement to vertical placement, and the length of the bicycle is greatly reduced. Two auxiliary small wheels (7) land on the ground, and front and rear wheels (2,5) form a three-wheeled shopping cart. Fig. 3 and Fig. 4 are two different perspective views after being folded into a shopping cart.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
