Abstract
The invention discloses a pull-rod schoolbag. The pull-rod schoolbag comprises a schoolbag body and a pull rod which is provided with idler wheels, wherein the bottom of the schoolbag body is detachably connected with a base; the bottom of the base is detachably connected with at least two foldable supporting columns; the idler wheels of the pull rod are triangular idler wheels. The four sides of the bottom of the schoolbag body are connected with the base by zippers or a plurality of buckles. The base is made from a deep-color rubber material. By adopting the structure, the base is connected with the schoolbag body by the zippers and the buckles; the base can be replaced by opening the zippers or the buckles; meanwhile, the foldable supporting columns are dismountable, so the replacement cost is saved. Besides, the idler wheels of the pull rod are designed in a triangular shape, so the idler wheels cannot roll downwards and can provide convenience for climbing a stair. Furthermore, the base is made from the deep-color rubber material and can be manufactured in batch, so the replacement cost is low; meanwhile, the base is resistant to dirt due to the deep color and is good in wear resistance due to the rubber material.
Description
Technical field
The application relates to a kind of student's school bag, particularly a kind of pull bar school bag.
Background technology
At present, for lightening the students' load, the use of pull bar school bag more and more receives an acclaim with universal.But, the bottom of pull bar school bag need often with ground or other object contact, be vulnerable to clash into or rub, after using a period of time, the bottom of pull bar school bag is easily the worst, if bottom occurs that school bag just can not re-use by that whole pull bar damaged, again can only buy a new pull bar school bag.Like this, larger waste will be caused.Therefore a kind of school bag changing bottom of design is badly in need of.
application content
The technical problem that the application will solve is for above-mentioned the deficiencies in the prior art, and provides a kind of bottom replacing convenience, cost low and the pull bar school bag of climbing stairs.
For solving the problems of the technologies described above, the technical scheme that the application adopts is:
A kind of pull bar school bag, comprise the pull bar of school bag body and band roller, described school bag body bottom portion is removably connected with base, and this base bottom is removably connected with at least two support columns that can fold, and the roller of described pull bar is triangle roller.Described base can rotate relative to pull bar.
Described school bag body bottom portion surrounding has been connected by zipper base.
Described school bag body bottom portion surrounding is connected with base by multiple buckle.
Described base is made up of the elastomeric material of dark color.
After the application adopts said structure, above-mentioned base is connected with school bag body by slide fastener or snap, opens slide fastener or buckle, can realize the replacing of base, and meanwhile, the support column that can fold is detachable, saves the cost of replacing.Base can rotate relative to pull bar, and support bar can fold, therefore when not using, base and pull bar can be folded, convenient for collecting.In addition, the roller design of pull bar is triangle, and roller can not roll downwards, can facilitate the needs of stair climbing.Further, base is made up of the elastomeric material of dark color, can batch making, and replacement cost is low, and meanwhile, dark color bears dirty, and rubber abrasive-resistance is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of pull bar school bag of the application.
Wherein have: 1. school bag body; 2. base; 3. pull bar; 4. the support column that can fold; 5. slide fastener; 6. roller.
Detailed description of the invention
Below in conjunction with accompanying drawing and concrete better embodiment, the application is described in further detail.
As shown in Figure 1, a kind of pull bar school bag, comprises the pull bar 3 of school bag body 1 and band roller 6, is removably connected with base 2 bottom described school bag body 1, be removably connected with at least two support columns 4 that can fold bottom this base 2, the roller 6 of described pull bar 3 is triangle roller.
Bottom described school bag body 1, surrounding is connected with base 2 preferably by the mode of slide fastener 5 or multiple buckle, also can adopt other mode.Slide fastener 5 or buckle are separated with base 2, and be also separated with school bag body 1 by pull bar 3, this school bag body 1 also uses as common knapsack, improves the service life of pull bar school bag.
Described base 2 is made up of the elastomeric material of dark color.Can make in batches, change, use cost is low; Meanwhile, dark color compares and bears dirty, and rubber abrasive-resistance is good.
When after the wearing and tearing of school bag body 1 base 2, only need open slide fastener 5 or buckle, the quick-replaceable of base 2 can be realized, meanwhile, because the support column 4 that can fold is detachable, save the cost of replacing.In addition, the roller 6 of pull bar 3 is designed to triangle, and during stair climbing, roller 6 can not roll downwards.
