Description

Bicycle backseat fastener device

Technical Field

The utility model relates to the technical field of buckles, in particular to a bicycle backseat buckle device.

Background

With the development of the times, the bicycle is not only used as a vehicle for working and commuting, but also can be changed into a vehicle for loading personal things by appropriately adding accessories such as a goods shelf, a storage bag and the like to the bicycle. If riding exercise is carried out at ordinary times, the bicycle can also become a transportation means for long-time and medium-distance travel, and the bicycle is a good partner choice for traveling nowadays, which is different from a general traveling mode.

In general, a conventional bicycle rack is used by tying articles to the rack by means of elastic ropes, for example, patent TWI480198B discloses a bicycle rack with changeable height, which comprises a rack and a bracket tube, wherein the front section tube part and the rear section tube part of the bracket tube keep an inclined angle, the rack can be quickly assembled or disassembled by means of a quick-dismantling piece, the front section tube part is downwards combined with a seat cushion vertical tube sleeve, and is positioned at a higher position from a rear wheel when the seat cushion vertical tube sleeve is fixed to a bicycle seat cushion vertical tube, and the front section tube part is upwards combined with the seat cushion vertical tube sleeve, and is positioned at a lower position from the rear wheel when the seat cushion vertical tube sleeve is fixed to the bicycle seat cushion vertical tube, so that the bicycle rack with changeable height can be achieved. But are limited in use by the size of the article and the length of the bungee cord. For the goods shelf tied by using the elastic rope, the winding mode not only causes inconvenience to the operation of a user, but also causes the elastic rope to be exposed outside, so that the appearance is not attractive, and everyone can not accept the mode. In addition, the weight of the goods shelf is limited only by being fixed on the bicycle seat tube. Accordingly, various types of cargo baskets and cargo bags have been developed later for consumer purchase installation. For example, the TWI495592B patent discloses a comfortable-to-carry bicycle storage bag that is positioned with a bottom rigid rail relative to the bicycle rack slide, and that can be removed from the rack when not in use at ordinary times. However, the manner of using the sliding rail and the sliding group on the goods shelf for the goods placing bag is inconvenient, and a mechanism for accurately aligning the rail with the goods shelf of the bicycle is needed, so that the state of placing the goods placing bag without the goods placing bag is quite easy, but a user has difficulty in operating the goods placing bag with the goods placing bag, and even the user feels quite heavy when the user removes the goods placing bag.

In view of the foregoing, the inventor of the present application has provided a shelf fastener device that allows a user to quickly and easily install and remove the shelf fastener device, and has developed and designed related products in a large number of ways, and finally obtained a bicycle backseat fastener device through multiple experiments and tests.
