[0003] The living standard in modern society is getting better and better. Many ordinary people form cycling teams. They need to prepare sufficient supplies for long-term cycling, and water is a necessity. The positions on bicycles in the prior art that can hold water bottles are all smaller water bottles below 1L, and large PC barrels above 5L cannot be loaded. Therefore, insufficient water reserves often occur. In areas without water in the wilderness, water shortage is very dangerous. In addition, people in some towns and rural areas are also accustomed to drinking purified water. Due to the narrowness of some roads, two-wheeled vehicles are still the best means of transportation.

[0004] There are several disadvantages to using baskets / baskets to transport buckets: 1) Iron baskets are generally made of welded steel bars, which are large in size and weight, increasing the burden on riders; 2) Buckets tend to shake in the basket, making the ride unbalanced; 3) The connection between the inner side of the basket and the rear frame is unstable and can easily fall off when the vehicle tilts.

[0021] The present invention is further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0022] See also Figures 1 to 4 The utility model provides a bicycle rear rack for loading barrel-shaped objects, including a support frame symmetrically arranged on both sides of a vehicle body, the support frame including a top beam 1 and a side beam 2, the front end of the top beam 1 is fixedly connected to the upper part of the frame, the front end of the side beam 2 is fixedly connected to the lower part of the frame, the top beams 1 on both sides of the vehicle body are fixed by connecting rods 3, and the rear ends of the top beam 1 and the side beams 2 are integrally fixedly connected; a loading frame body 4 is also provided, the loading frame body 4 is fixedly connected to the outer side of the support frame, both sides of the loading frame body 4 are fixedly connected to strap connecting rings 42, the middle part of the loading frame body 4 is fixedly connected to an arc-shaped clamping rib 43, and a base 44 is provided at the bottom of the loading frame body 4.

[0023] The rear frame of the bicycle is designed as a triangular support frame, two points of which are connected to the bicycle body, and the assembly is very convenient. The top beam 1 and the side beam 2 are fixed at a certain angle to form a stable triangular load-bearing frame. The object frame 4 and the support frame are integrated into a customized rear frame structure. The object frame 4 is particularly suitable for fixing barrel-shaped objects, which is convenient for users to carry bottled water.

[0024] Specifically, the object carrier body 4 includes two longitudinal support ribs 41, the upper ends of the longitudinal support ribs 41 are welded and fixed to the top beam 1, and the lower parts are welded and fixed to the side beams 2; the strap connection rings 42 are arranged on the outer sides of the two longitudinal support ribs 41 that are far away from each other; the two longitudinal support ribs 41 are connected to the arc-shaped clamping ribs 43 by welding points; the base 44 is an L-shaped bend at the lower end of the longitudinal support ribs 41, and the length of the base 44 is greater than the radius of the arc-shaped clamping ribs 43. The object carrier body 4 of this embodiment is also composed of light rods, which are light in weight and small in size, and are convenient for rear rack installation and water bucket installation. In this solution, the base 44 of the object carrier body 4 is a protruding structure that extends outward horizontally. Figure 2 In the embodiment shown, the length of the base 44 is set to be equal to the diameter of the arc rib. Usually, the base 44 should not exceed this limit too much, otherwise it will be unnecessary. The base 44 supports the bottom of the object. When there is no object loaded, it is a protruding structure. In order to avoid the structure accidentally hurting the user, on the basis of the above embodiment, the outer ends of the two longitudinal support ribs 41 are connected by a semi-arc rod, so that the outer end of the base 44 is smooth to avoid bruising the user or passers-by.

[0025] The arc-shaped clamping ribs 43 in this solution are used to constrain the barrel body from both sides. To facilitate the installation of barrel-shaped objects, the arch height of the arc-shaped clamping ribs 43 should be less than the radius of the barrel-shaped object; because this solution is also designed to fix the barrel-shaped object with a strap, the radius of the arc-shaped clamping ribs 43 is not required to completely match the radius of the barrel-shaped object carried, and the radius of the arc-shaped clamping is set to be slightly larger than the radius of the barrel-shaped object usually to be loaded. Furthermore, the material of at least the two ends of the arc-shaped clamping ribs 43 is not limited to steel bars, and a material with a certain elasticity can also be used, so that barrel-shaped objects of different diameters can contact the surface of the barrel body after being loaded, forming a better clamping.

[0026] As an option, the arc-shaped clamping ribs 43 and the strap connecting ring 42 are arranged in a staggered manner in height. This embodiment allows the water bucket to have more fixing points in height.

[0027] As an option, two arc-shaped clamping ribs 43 are arranged in the upper and lower parts, and two pairs of strap connection rings 42 are arranged in the upper and lower parts. The fixing stability of the bucket is better.

[0028] The strap connecting ring 42 in the present scheme can be made of C-shaped steel bars or U-shaped steel bars; the strap can be an elastic band with a width of 3-5 cm, or it can be a hemp rope or the like. The strap connecting ring 42 is not limited to connecting one strap. Preferably, a pair of strap connecting rings 42 located at the upper part are close to the upper end of the longitudinal support rib 41. The upper strap connecting ring 42 of this embodiment can be used not only to connect the binding straps of the side buckets, but also to connect the binding straps of the items on the top of the rear frame. At the same time, in order to make the top bucket be placed more stably, the connecting rod 3 connecting the top beams 1 on both sides can be designed as an arc-shaped connecting rod 3.

[0029] The beneficial effects of the utility model are: 1) the cargo racks on both sides of the scheme adopt semi-enclosed frames, with less steel materials and light overall weight, which effectively reduces the weight of the additional load; 2) the scheme adopts a guard frame matching the barrel structure to provide an adaptive constraint space to prevent the barrel from shaking; 3) the cargo rack body of the scheme is welded integrally with the rear rack body, which has good rigidity and strong stability.

[0030] The above description is only a preferred feasible embodiment of the present utility model, and does not limit the scope of rights of the present utility model. All equivalent changes made using the contents of the present utility model specification and its drawings are included in the scope of rights of the present utility model.
