Description
Technical field
It the utility model is related to a kind of back of knapsack, and the knapsack using the back.
Background technology
Children's knapsack is children's knapsack used in everyday, and still, some existing knapsacks are made of simple soft cloth, then
Knapsack does not have shape, and the article of the inside easily directly oppresses children back, and harm is produced to children's health.Other existing back ofs the body
Bag inherently can produce compressing using the high material of hardness, then knapsack back to the vertebra of children.
Present children's lessons weight is additionally, since, it is necessary to the weight of the back of the body is very heavy, thus knapsack need in itself high intensity so as to
Adapt to such case.
Therefore, the back with the knapsack of children's back contact is critically important for the structural strength of knapsack and the health of children
Structure.
In the prior art at present, improving technology has his own strong points, but effect is not fairly obvious.
The content of the invention
The utility model provides a kind of children's knapsack back of EVA one pressing mold shaping, and the purpose is to solve prior art
The shortcomings that existing, make product firm, adapt to the back of children and mitigate the compressing to vertebra, good permeability.
The utility model also provides the knapsack using above-mentioned back
Technical scheme is used by the utility model solves its technical problem：
A kind of children's knapsack back of EVA one pressing mold shaping, it is characterised in that：It is integrated the EVA materials of pressing mold shaping
The plates of matter, there is back region and chassis area.
Further, it can bend plates along the connecting portion between back region and chassis area.
Further, ventilative groove is easy in back region by pressing mold plastotype, formation.
The utility model also provides a kind of children's knapsack, it is characterised in that：It is integrated the piece of the EVA materials of pressing mold shaping
Shape body, its back have back region and chassis area, can bend plates along the connecting portion between back region and chassis area；Tool
There is inclusion of the sewing on back.
It is of the present utility model to be beneficial in that：
Back uses integrated Mould design, and back and bottom integration compacting are formed, and the later stage is sewn into by folding again
Above knapsack inclusion, effective supporting role can be played, allows inclusion to be unlikely to deform.EVA material is light and flexible and plasticity,
Back can more be protected by being combined with human body back.Ventilating groove plays permeation functions, and chassis slot plays waterproof and supporting role.
Brief description of the drawings
Fig. 1 is structure chart of the present utility model.
Embodiment
In order to illustrate more clearly of the technical solution of the utility model, the required accompanying drawing used in description will be made below
Simply introduce, it should be apparent that, drawings in the following description are only some embodiments of the utility model, for this area
For those of ordinary skill, on the premise of not paying creative work, other implement can also be obtained according to these accompanying drawings
Example.
As shown in Figure 1：
The utility model is a kind of children's knapsack back, and the back 1 is the shaping of whole piece EVA material one pressing mold, is
Plates, the outer surface of the plates are divided into two regions：
Superposed region is back region 20, has the back boss 2 of raised boss type, back boss 2 is in rectangular
Shape boss, at back, boss 2 is provided with some ventilating grooves 21, wherein four ventilating grooves 21, which surround one, is similar to rectangular envelope
Framework is closed, four angles for closing framework are located at four Angle Positions of back boss 2 respectively, have connection framework in the middle part of the boss of back
The horizontal ventilating groove 21 of the ventilating groove 21 of two sides.Back boss 2 can be set according to the S-type streamline pressing mold of spine shape
Meter, children back is more bonded when bearing, and weight effectively can be distributed into both sides muscle, improves middle vertebra power under pressure,
Overcome the even back pain of backside pressure caused by bearing school bag for a long time, do not oppress vertebra, protect vertebra healthy development.It is ventilative
Groove 21 can make air conducting, flowed between the part at contact back and the part for not contacting back, breathe freely and keep back
It is dry and comfortable, bear more comfortable.
It is chassis area 30 positioned at the region of bottom, the chassis boss 3 with raised boss type, chassis boss 3 is in rectangular
Shape boss, on chassis, boss 3 is provided with the chassis slot 31 for the arc that two both ends connect with a side of chassis boss 3.Bottom
Portion is protectiveness chassis design, formed one of chassis slot 31 effect be the bottom wrapped when floor is wet will not whole piece it is all wet
Fall, there is support role, another effect of chassis slot 31 is to turn into reinforcement and play integrally stiffened effect, prevents from becoming
Shape can be effectively protected article in knapsack and be not easy to break, antidetonation.
Because EVA is flexible and extensibility, so along between the back region 20 and chassis area 30 of integral compression molding
Connecting portion 4 can make plates be bent to rectangular shaped, and then sewing on inclusion 5 and shoulder belt just turns into knapsack.Integral type is compression molded into
Bending makes back and chassis be the EVA material with intensity after type, the intensity of back is ensure that, without again by back and chassis
Sewing combines.
Inclusion 5 uses the ultralight nylon facing material of import high density, and light and handy durable, safe material reaches European Supreme Procuratorate's mark
Standard, meet children's health, material safety, environment-friendly strict sale standard.
It is of the present utility model light and handy, the custom of bearing of child is taken into full account, use is abundant, has the EVA materials of supporting role
Matter makes back design, and antidetonation is depressurized while protecting lumbar vertebrae, alleviates back fatigue or discomfort caused by discontinuity.
Each embodiment is described by the way of progressive in this specification, what each embodiment stressed be and other
The difference of embodiment, between each embodiment identical similar portion mutually referring to.To the upper of the disclosed embodiments
State bright, professional and technical personnel in the field is realized or using the utility model.A variety of modifications pair to these embodiments
It will be apparent for those skilled in the art, generic principles defined herein can not depart from this reality
In the case of with new spirit or scope, realize in other embodiments.Therefore, the utility model is not intended to be limited to this
These embodiments shown in text, and it is to fit to the most wide scope consistent with principles disclosed herein and features of novelty.
