Description
Technical field
The utility model relates to case field, specifically a kind of pull bar knapsack of rational in infrastructure, easy to use, more stable and stronger.
Background technology
As everyone knows, knapsack widely uses in people's daily life, wherein backpack due to have light, portable, capacity large, bear comfortable, two symmetrically arranged shoulder belts the feature such as active balance pressure can especially obtain the favor of user.Current backpack on the market still mainly relies on double-shoulder belt bearing pressure, and in order to improve knapsack capacity, create pull bar bag, pull bar bag is primarily of inclusion, pull bar composition, wherein be provided with roller bottom pull bar, Knapsack structure is simpler, be generally bag, be fixed on drag link mechanism by belt body or velcro, during use, the expansion link of drag link mechanism stretched out, by dilatory expansion link top handle, drive inclusion moves, because the inclusion weight of pull bar bag is carried by drag link mechanism, effectively can alleviate user and bear a heavy burden, be more suitable for Large Copacity case and bag.
Present stage is surrounded by a lot for the Dual-shoulder that children use, to bear a heavy burden the harmful effect that children's bone is produced to alleviate inclusion, researcher and manufacturer develop that multiple good permeability, braces are firm, the uniform children's backpack of load, but less effective, comfortableness and jumbo requirement cannot be taken into account simultaneously.
Summary of the invention
The utility model, for the shortcoming and defect existed in prior art, proposes a kind of pull bar knapsack of rational in infrastructure, easy to use, attractive in appearance, more stable and stronger.
The utility model can be reached by following measures:
A kind of pull bar knapsack, it is characterized in that comprising drag link mechanism and backpack, backpack and drag link mechanism are provided with the four-part button matched, backpack is fixedly connected with drag link mechanism through four-part button, the belt body for forming two shoulder belts and handle is simultaneously provided with inside the inclusion of described backpack, belt body is fixed on inclusion inside top, riveted by four-part button and inclusion, and four-part button is simultaneously for cylinder lever connecting rod mechanism and inclusion, belt body extends upward arc shaped handle, simultaneously to downward-extension two braces, inclusion Lower Half bilateral symmetry is provided with order type and buckles, two order type deduction of points are not connected with two braces of belt body to downward-extension, form double-shoulder belt, shoulder belt length can be changed by regulating order type to buckle
The utility model is in order to improve steadiness further, a liner belt for backpack inclusion and drag link mechanism being fixed is provided with in the inner side of backpack, the two ends of liner belt can be connected with backpack both sides, make to form hollow layer between liner belt belt body and inclusion, during use by drag link mechanism through liner belt belt body and inclusion, backpack and drag link mechanism can be made to fit, by the width of extension liner belt, stable connection can be improved further.
The utility model inclusion inside top is provided with plastic plate interlayer, for riveting four-part button, and improves the support fixed effect to inclusion.
In use, drag link mechanism can be separated with both shoulders bag the utility model, makes it, as independently both shoulders bag use, lint material all can be adopted to make, bear comfortable inside liner belt and both shoulders bag, easy to carry, and dismounting position flat appearance is attractive in appearance; When bearing a heavy burden larger, backpack can be fixed on drag link mechanism by the liner belt inside four-part button and inclusion, the expansion link had by drag link mechanism, roller etc., mobile inclusion, now by order type buckle double-shoulder belt is transferred to the longest after fill in liner belt, prevent double-shoulder belt from exposing and mop floor or other objects of hook, effectively alleviate the pressure of inclusion to children's torso.
The utility model compared with prior art, rational in infrastructure, easy to use, can take into account that both shoulders bag is light simultaneously, the function of the characteristic of portable and pull bar bag, effectively can alleviate user simultaneously when inclusion is overweight and bear a heavy burden, be specially adapted to children and use.
accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is structural representations of backpack in the utility model.
Reference numeral: drag link mechanism 1, backpack 2, liner belt 3, belt body 4, four-part button 5.
detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the utility model proposes a kind of pull bar knapsack, it is characterized in that comprising drag link mechanism 1 and backpack 2, backpack 2 and drag link mechanism 1 are provided with the four-part button 5 matched, backpack 2 is fixedly connected with drag link mechanism 1 through four-part button, the belt body 4 for forming two shoulder belts and handle is simultaneously provided with inside the inclusion of described backpack 2, belt body 4 is fixed on inclusion inside top, riveted by four-part button 5 and inclusion, and four-part button 5 is simultaneously for cylinder lever connecting rod mechanism and inclusion, belt body 4 extends upward arc shaped handle, simultaneously to downward-extension two braces, inclusion Lower Half bilateral symmetry is provided with order type and buckles, two order type deduction of points are not connected with two braces of belt body to downward-extension, form double-shoulder belt, shoulder belt length can be changed by regulating order type to buckle.
As shown in Figure 2, the utility model is in order to improve steadiness further, a liner belt 3 for backpack 2 inclusion and drag link mechanism 1 being fixed is provided with in the inner side of backpack 2, the two ends of liner belt 3 can be connected with backpack 2 both sides, make to form hollow layer between liner belt 3 belt body and inclusion, during use by drag link mechanism 1 through liner belt 3 belt body and inclusion, backpack 2 and drag link mechanism 1 can be made to fit, by the width of extension liner belt 3, stable connection can be improved further.
