Abstract
The utility model discloses a foldable draw-bar backpack. The foldable draw-bar backpack mainly comprises a backpack body and a draw bar piece, wherein the draw bar piece comprises a draw head, a draw bar and a base, which are sequentially connected with one another; the draw bar runs through a sandwich layer on the back surface of the backpack body, and the base is supported on the bottom of the backpack body; the base is provided with a slot with an opening facing up, the draw bar is movably hinged into the slot, and the side wall of the slot, facing the backpack body, is provided with a notch by which the draw bar can move and rotate. The draw bar is movably connected with the base, and the connection structure is simple and reasonable; the foldable draw-bar backpack is simple to fold and is compact in structure and occupies a small space after being folded; thus the draw bar is very convenient to transport and carry.
Description
Technical field
The utility model relates to a kind of pull bar knapsack, specifically refers to the folding pull bar knapsack of a kind of pull bar.
Background technology
At present on a lot of backpacks, all can be provided with idler arm, bear morely during compared with heavy articles, can use pull bar to tow to replace and bear, to alleviate walk load.Pull bar knapsack is upper outside except being applied in packsack, applies greatly at present on primary and secondary students' school bag.Existing pull bar Knapsack structure includes knapsack body and idler arm, and idler arm comprises the base, pull bar and the pull head that connect successively setting.Pull bar penetrates the interlayer at the knapsack body back side, and base is supported in knapsack body bottom, base and pull bar vertical setting mutually.The base of current most of pull bar knapsack and pull bar are vertical being fixedly installed mutually, thereby it is folding that pull bar knapsack can not be compressed, and structure is not compact, take up space, and the utmost point such as is unfavorable for transporting, carry at the running.
In view of this, the problem that the inventor exists for existing pull bar knapsack conducts in-depth research, and this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of folding draw-bar knapsack, and folding structure brings compact conformation, is beneficial to transport and carries texts.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of folding draw-bar knapsack, mainly comprises knapsack body and idler arm, and this idler arm comprises the pull head, pull bar and the base that connect successively setting; Described pull bar penetrates the interlayer at the described knapsack body back side, and described base is supported in described knapsack body bottom; Described base is provided with an opening up slot, and described pull bar is movably hinged in this slot, and the corresponding surface of this slot offers the breach for described pull bar moving rotary in the sidewall locations of described knapsack body.
Described slot and the described breach formation one on it are the draw-in groove of C type shape.
The pull bar of described idler arm is provided with side by side two, offers two corresponding described slots on described base.
Adopt after such scheme, this Novel photo is for the beneficial effect of prior art: between pull bar and base, be movable connection, and syndeton is very rationally succinct.In the time that pull bar coupling is inserted in slot, pull bar is mutually vertical with base, now pull bar knapsack in deployed condition for normally.Need to fold time, operation pull bar makes its relative base go out from moving rotary in breach, and base upwarps before knapsack body, it is folding that pressing pull bar and base are realized pull bar knapsack, folding operation is very simple, folds rear compact conformation, does not take up space, and has promoted thus the convenience in transporting and carrying.
Accompanying drawing explanation
Fig. 1 is the structural representation of this Novel pull rod knapsack deployed condition;
Fig. 2 is the schematic rear view of this Novel pull rod knapsack folded state;
Fig. 3 is the front schematic view of this Novel pull rod knapsack folded state.
Label declaration
Knapsack body 1 interlayer 11
Pull head 2 pull bars 3
Breach 411 pulleys 5
The specific embodiment
Below in conjunction with the drawings and specific embodiments, this case is described in further detail.
This is novel relates to a kind of folding draw-bar knapsack, as Figure 1-3, mainly comprises knapsack body 1 and idler arm, and idler arm comprises and connects successively the pull head 2, pull bar 3 and the base 4 that arrange.Pull bar 3 penetrates the interlayer 11 at knapsack body 1 back side, and base 4 is supported in the bottom of knapsack body 1.
Originally novel main innovate point is, pull bar 3 is mutually and is movably hinged with base 4, and particularly, base 4 is provided with an opening up slot 41, and pull bar 3 is movably hinged in slot 41 by jointed shaft (not shown).The corresponding surface of slot 41 is supported or opposed in the sidewall locations of inclusion 1 and is offered breach 411, and by this breach 411, pull bar 3 relatively base 4 carries out moving rotary.
As shown in Figure 1, when pull bar 3 is inserted in slot 41 when interior matchingly, pull bar 3 is mutually vertical with base 4, now pull bar knapsack in deployed condition for normally.When pull bar knapsack need to fold, as Figure 2-3, operation pull bar 3 makes its relative base 4 go out from breach 411 moving rotaries, and base 4 upwarps above toward knapsack body 1, and it is folding that pressing pull bar 3 and base 4 are realized pull bar knapsack, and folding operation is very simple.
Preferably, slot 41 and the breach 411 on it form a draw-in groove (referring to Fig. 2) that is C type shape.The draw-in groove of this C type shape is plastic material, and it has certain elastic force, when folding, exerts oneself a little, and pull bar 3 can go out from breach 411 moving rotaries.When pull bar 3 is inserted in slot 41 when interior matchingly, the draw-in groove of C type shape holds pull bar 3 and spins out from slot 41 to prevent it.
Preferably, the pull bar 2 of idler arm is provided with side by side two, offers two corresponding slots 41 on base 4.Certainly the slot 41 on pull bar 2 and base 4 can correspondence only arranges one and also can.
The foregoing is only this novel preferred embodiment, all equalizations of doing with this novel claim scope change and modify, and all should belong to the scope of this novel claim.
