Description

A kind of knapsack of extendible capacity

Technical field

The utility model relates to a kind of knapsack, in particular to a kind of knapsack of extendible capacity.

Background technique

With the rapid raising of people's living standard, people go on a journey in daily life and travel outdoors process in vacation In, can all need to carry some articles for daily use using knapsack, in order to go on a journey or tourism process in use.But it is actually using In, when knapsack need to place the biggish article of volume or user travel outdoors need to carry more object when, knapsack is then There is no enough space packages to use；And when knapsack does not need to place the biggish article of volume or daily trip, knapsack is again It can seem too fat to move ugly because volume is larger, influence the beauty of knapsack shape, do not meet the consumption demand that user follows the fashion.

Utility model content

Therefore, for above-mentioned problem, the utility model proposes a kind of structure is simple, can according to place article volume into The knapsack of the extendible capacity of row Space adjustment.

To realize above-mentioned technical problem, the solution that the utility model is taken are as follows: a kind of knapsack of extendible capacity, including packet Body, the backpack body are equipped with the accommodating chamber for placing article, and the accommodating chamber is equipped with taking mouth, and the accommodating chamber, which is equipped with, to expand Hold structure, the extendible capacity structure includes the blinds side being located in the accommodating chamber cavity wall, and the blinds side can be real Existing folding shrinking sprawls dilatation, be located in the accommodating chamber blinds side two sides be equipped with respectively fixed main ring and it is fixed from Ring, is formed with fixed interval (FI) between the fixed main ring and blinds side, the fixed main ring is located at the side wall in fixed interval (FI) On be embedded with falope ring, be convexly equipped with fixed lobe on the falope ring；The fixation is equipped with fixation hole from ring；When blinds side When folding shrinking, the fixation can be placed in the fixed interval (FI) from ring, and the fixed lobe of the falope ring can be embedded in solid Due to the fixation from the fixation hole of ring.

Further, the fixed lobe is hemispherical projections, the circumference of the fixed main ring in fixed lobe edge is successively Arranged distribution.

By using preceding solution, the beneficial effects of the utility model are: the back of the extendible capacity designed as described above Packet, placing, article volume is little, when accommodating chamber space requirement is small, fixed main ring and it is fixed from ring by fixed lobe, The cooperation of fixation hole achieves a fixed connection, then blinds side being capable of folding shrinking and fixation；And with place article increase or Person's bulky items are put into, and accommodating chamber is gradually softened, and blinds side two sides have separation force, and separation force makes It is actively separated from each other and dismantles between fixed lobe, fixation hole, fixed main ring and fixation are released from fixed function between ring, then blinds Side can be softened to sprawl dilatation, so that accommodating chamber volume expands to adapt to place the volume needs of article, when dilatation is not necessarily to The other operation processing of user；Therefore, the Knapsack structure of the extendible capacity is simple, can carry out space according to article volume is placed It adjusts, it is easy to operate, it is practical；And the embedded fixed disassembly separated structure that extendible capacity structure uses, it is entirely different It is adjusted in conventional zipper folding and bandage, structure is hidden, will not influence the design of knapsack exterior appearance, and have to be different from and take object The distinction of mouth opening-closing structure, can be avoided the maloperation taken between object and dilatation, practical.Further, on falope ring Fixed lobe be dispersed annular array, then each independent fixed lobe can respectively with corresponding fixation hole Separation or fixed occurs, therefore, when special-shaped article is put into, the shape that accommodating chamber can carry out adapting to special-shaped article volume expands Hold.

Structural schematic diagram when Fig. 1 is the utility model embodiment blinds side folding shrinking.

Fig. 2 is structural schematic diagram when dilatation is sprawled in the utility model embodiment blinds side.

Fig. 3 is the structural schematic diagram of the utility model embodiment extendible capacity structure.

Specific embodiment

Now in conjunction with the drawings and specific embodiments, the present invention will be further described.

Referring to figs. 1 to Fig. 2, the utility model embodiment is disclosed, a kind of knapsack of extendible capacity, including backpack body 1, described Backpack body 1 is equipped with the accommodating chamber for placing article, and the accommodating chamber is equipped with taking mouth 11, and the accommodating chamber is equipped with extendible capacity knot Structure, the extendible capacity structure include the blinds side 12 being located in the accommodating chamber cavity wall, and the blinds side 12 can be real Existing folding shrinking sprawls dilatation, and the two sides that blinds side is located in the accommodating chamber are equipped with fixed main ring 13 respectively and fix From ring 14, fixed interval (FI) is formed between the fixed main ring 13 and blinds side 12, the fixed main ring 13 is between fixing It is embedded with falope ring 15 on side wall in gap, fixed lobe is convexly equipped on the falope ring 15, the fixed lobe is hemispherical Protrusion, the fixed lobe are arranged successively distribution along the circumference of fixed main ring；The fixation is equipped with fixation hole from ring 14；When hundred When 12 folding shrinking of leaf side, the fixation can be placed in the fixed interval (FI) from ring 14, and the fixation of the falope ring 15 is convex It rises to be embedded in and is fixed on the fixation from the fixation hole of ring 14.

The knapsack of the extendible capacity designed in summary, structure is simple, can carry out Space adjustment according to article volume is placed, It operates conveniently, it is practical.

The foregoing descriptions are merely the embodiment using this origination techniques content, any those skilled in the art use this wound Make done modifications and changes, all belong to the scope of the patents of this creation opinion, and is not limited to those disclosed embodiments.
