Abstract
The utility model relates to schoolbags. The school bag of adjustable content in the frame and lever structure adjusts the content according to how many books can be held within a certain range. Two frames (1) on both sides are provided with a small hole and a long slot and two crossed motion levers (2) are provided with a small hole respectively on both sides. The small hole and the long slot on the lateral frame are connected with the small hole on the lever through a pin (10), both ends of the lever respectively rotate in the small hole on the lateral frame and move to and fro in the long slot, in order to make the two frames horizontally move after the two crossed motion levers are connected through the pin. The inside of the frames is provided with a lever on both internal sides and a baffle on the bottom while the outside is connected with a foldable skin and a cloth (9). The front and the back faces of the frame are connected with a flexible cloth (3), thus forming a rectangular container of variable content. A hook (5) arranged on an elastic (6) is clamped on a hooked strip (4) so as to cover a schoolbag lid (8) and press a schoolbag belt (7). The school bag of adjustable content in the frame and lever structure can be applied to schoolbags in need of adjustable content. The utility model has the advantages of convenient use, book protection and pleasing appearance.
Description
The utility model relates to the bag class, particularly relates to school bag.Can come the framework lever construction variable capacity school bag of pondage according to the size of putting the books volume within the specific limits.Framework lever construction variable capacity school bag, can be applied to needs on the school bag of adjustable capacity.
The school bag of student's use now, the capacity of school bag can not be regulated according to the size of putting the books volume.When the student used school bag, what books were put very little can be chaotic.The inconvenience when student uses is damaged books easily, and profile is not attractive in appearance.
The purpose of this utility model is at the above shortcoming; provide a kind of within the specific limits can be according to the size of putting the books volume; come the framework lever construction variable capacity school bag of pondage, framework lever construction variable capacity school bag makes things convenient for when the student uses, can protect books, good looking appearance.
The purpose of this utility model is achieved in that designing pair of frames does parallel relative motion after two secondary crisscross motion levers connect with pin.Two of pair of frames both sides has aperture and elongated slot respectively, and two has aperture respectively on the lever of two secondary crisscross motion levers.The aperture on aperture on the frame, elongated slot and the lever and the size of pin will match, aperture on the frame and elongated slot are with after aperture on the lever is connected with pin, rotation is done respectively in lever two in the aperture on the frame, in elongated slot, do moving back and forth, make pair of frames after two secondary crisscross motion levers connect with pin, do parallel relative motion.The both sides of pair of frames has two secondary crisscross motion levers, bottom that baffle plate is arranged, and the outside is connected with folding skin, cloth.The front-back of framework becomes the variable-displacement cuboid container with the capping of elastic force cloth.With having contact with on the elastic cord, ride on the hook groove bar again, school bag is covered, by last school bag braces.How many framework lever construction variable capacity school bags can come pondage according to putting books within the specific limits, and can be applied to needs on the school bag of adjustable capacity.Thereby reach the purpose that framework lever construction variable capacity school bag can make things convenient for, can protect books, good looking appearance when the student uses.
How many utility model patents can come pondage according to putting books within the specific limits, is a kind of novel frame lever construction variable capacity school bag.
Describe in detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation.
Fig. 2 is the installation diagram of framework, lever, pin.
Fig. 3 is a secondary crisscross motion lever stereogram.
Fig. 4 is folding skin, cloth stereogram.
Fig. 5 is retracted to the schematic diagram of minimum volume for framework lever construction variable capacity school bag.
Design a kind of framework lever construction variable capacity bag, as Fig. 1 it comprise pair of frames (1), two secondary crisscross motion levers (2), elastic force cloth (3), hook groove bar (4), have contact with (5), elastic cord (6), school bag braces (7), school bag lid (8), folding skin, cloth (9), pin compositions such as (10).As each secondary crisscross motion lever of Fig. 3 two levers the length are arranged, connect with minor axis, make between two levers and do crisscross motion, aperture is arranged at two of lever at the central of two levers.Respectively there is deep trouth both sides as Fig. 2 pair of frames (1) framework, and the length of deep trouth, width equate that with length, the thickness of each auxiliary lever (2) lever can move in deep trouth.Two on the frame of the both sides of pair of frames has aperture and elongated slot respectively, and there is aperture respectively at two on the lever of each secondary crisscross motion lever.The aperture on aperture on the frame, elongated slot and the lever and the size of pin will match, aperture on the frame and elongated slot are with after aperture on the lever is connected with pin (10), rotation is done respectively in lever two in the aperture on the frame, in elongated slot, do moving back and forth, make pair of frames after two secondary crisscross motion levers connect with pin, do parallel relative motion.Elongated slot on the frame of pair of frames both sides, elongated slot length have determined the scope of crisscross motion lever motion.Because in the middle of each the secondary crisscross motion lever on the frame, do crisscross motion, make two aperture do parallel relative motion, one of lever is fixed in the aperture after connecting with pin and rotates, the other end connects the back with pin and do parallel motion back and forth in elongated slot, has also determined the size of the parallel relative motion amplitude of framework.The both sides of pair of frames has two secondary crisscross motion levers, bottom that baffle plate is arranged, and has formed adjustable within the specific limits cuboid container.Can shrink amplification as the folding skin of Fig. 4, cloth.And for example the both sides of Fig. 1 pair of frames is connected with folding skin, cloth (9) with the bottom, and folding skin, cloth can shrink amplification when pair of frames is done parallel relative motion.The framework front-back is connected with elastic force cloth (3), takes, makes things convenient for when putting books.Elastic cord (6) has deflation and regulating action.The length of hook groove bar (4), school bag lid (8) is decided by the size of the parallel amplitude of relative accommodation of pair of frames, the hook groove bar degree of tightness that groove has a row can regulate elastic cord of rising to the bait.With having contact with on the elastic cord (5), ride in the hook groove of hook groove bar, clad is covered, by last school bag braces (7), form the school bag of framework lever construction variable capacity.It is a kind of novel frame lever construction variable capacity school bag.Be retracted to the framework lever construction variable capacity school bag of minimum volume as Fig. 5.Framework lever construction variable capacity school bag can come pondage according to the size of putting the books volume within the specific limits.Thereby reach the purpose that framework lever construction variable capacity school bag can make things convenient for, can protect books, good looking appearance when the student uses.
The utility model patent can make and wrap in the capacity that can regulate school bag in the certain limit according to the size of putting the books volume, is a kind of novel frame lever construction variable capacity bag.Framework lever construction variable capacity school bag need on the school bag of adjustable capacity can be applied to.
