Technical Field

the invention belongs to the technical field of sports bicycle production, and relates to a low-wind-resistance medium-distance and long-distance sports bicycle built-in feeding system.

Background

With the improvement of social economic level and living level, sports such as sports are rapidly developed, wherein bicycle sports also becomes one of choices of a plurality of sports enthusiasts and professional sporters. For bicycle competition, besides being related to physical quality and riding skill of competitors, whether the design of the bicycle per se can effectively reduce riding resistance is important, and in the field of highway and mountain bike competition which is in the must of minutes and seconds, 0.1s can also determine the champion of a bicycle racing hat with the riding time of several hours, so that the reduction of the riding resistance to the maximum degree becomes the unrelenting pursuit of designing, manufacturing and riders of the competitive bicycles. Because the distance of the medium-distance and long-distance competitions is long, the athletes need to supplement water in the riding process, and at present, the competitive bicycle for the purposes at home and abroad is additionally provided with a kettle rack at the front triangular position of a frame for placing a kettle. The kettle rack and the kettle are placed and protrude out of the frame pipe, the appearance of the kettle rack and the kettle is optimized, and the fluid resistance coefficient cannot reach zero due to the existence of the external volume of the kettle rack and the kettle, so that the riding wind resistance area is increased by the arrangement of the kettle rack and the kettle of the existing competitive bicycle, and the riding wind resistance is increased. And when the kettle falls into a bumpy road section, the kettle can fall off the kettle rack to cause the loss of the feeding, and the kettle falling off the ground can also prevent other athletes of the same team from riding and even threaten the safety of the following riders. If the participant gets off the car and picks up after the kettle drops, the athlete can delay the riding energy in the kettle taking process, and the middle-long distance riding score is influenced.

Disclosure of Invention

The invention provides a novel low-wind-resistance built-in feeding system for a medium and long distance competitive bicycle, aiming at the problems in the design of the traditional competitive bicycle.

In order to achieve the purpose, the invention is realized by adopting the following technical scheme:

a low-wind-resistance middle-distance sports bicycle built-in feeding system comprises a water bag arranged in a bicycle body tube and a guide tube communicated with the water bag to extend out, wherein a liquid discharging switch and a guide tube spring winder facilitating extension and retraction of the guide tube are arranged on the guide tube.

Preferably, a backflow-preventing quick liquid filling connector is arranged between the liquid discharging switch and the water bag.

Preferably, the connecting end of the conduit is provided with an open gravity ball.

Preferably, the water bag is formed by connecting water bag monomers in a plurality of hollow frame tubes in series or in parallel.

Preferably, the water sac, the conduit and the gravity ball are all made of food-grade materials. The water sac is formed by performing blow molding processing on woven reinforced fibers and food-grade silica gel, rubber or plastics, and the end part of the water sac is formed by a hemispherical or conical end cap protruding outwards.

The pressure intensity of the fluid in the water sac is higher than the pressure intensity of the external air pressure, and the fluid in the water sac can flow out along the catheter under the action of the pressure difference of the fluid and the external air pressure.

The method for installing the low-wind-resistance medium-distance sports bicycle built-in feeding system comprises the following steps

S1: placing the water bag into a hollow frame tube;

S2: the backflow-preventing quick liquid filling connector, the liquid discharging switch and the conduit spring winder which are connected with the conduit are fixed on the frame;

s4: and closing the liquid discharging switch, and pressing the liquid feed into the water bag through the backflow-preventing quick liquid charging connector to enable the pressure intensity of the liquid in the water bag to be greater than the pressure intensity of the external air pressure.

compared with the prior art, the invention has the advantages and positive effects that:

1. Compared with the traditional kettle rack and kettle structure, the built-in water bag structure has small exposed area and cannot damage the overall streamline of the frame. Can greatly reduce wind resistance, reduce the physical energy consumption during riding and improve the athletic performance of athletes.

2. The kettle with the built-in water bag fixed relative to the kettle rack has higher safety, and the kettle can not fall off due to the jolt of the road to cause the loss of the nutrition, and the timeliness of the supply is influenced to influence the sports score.

3. The rider can complete the operation with one hand in the riding process without screwing the cover with two hands, so that the liquid supply time of the athlete is shortened, the operation is convenient and fast, and the improvement of the athletic performance is facilitated.
