Abstract
The utility model discloses a novel lightening schoolbag, which comprises a schoolbag body. A gas bag chamber is molded on the schoolbag body, a soft gas bag is disposed in the gas bag chamber, the soft gas bag is filled with compressed inert helium gas, a gas filling valve is mounted on a gas filling hole of the soft gas bag, and a safety valve is mounted on the soft gas bag. As the soft gas bag is arranged in the schoolbag body, compressed inert helium gas is filled in the soft gas bag, and weight of the overall schoolbag can be greatly reduced by utilizing the principle that helium is lighter than air. When size of the soft gas bag is identical to that of the schoolbag, weight reduction can be determined according to volume of filled helium gas, weight reduction is increased along with increment of volume of the filled helium gas, and on the contrary, weight reduction is decreased along with decrement of volume of the filled helium gas. Additionally, the filled inert helium gas is nonflammable, non-explosive and fine in safety.
Description
Technical field:
The utility model relates to the school bag technical field.
Background technology:
School bag is the instrument that students is used for placing stationery.Be that each student who goes to school almost will use everyday, but along with present student's burden is more and more heavier, the weight of school bag is also in continuous increase, this does not also have complete supermature student for health, damages very big.Especially for the injury of backbone, cause the bending of backbone, distortion to produce even pathology because school bag is overweight easily.Therefore, just need a kind of school bag that can weight reduction.
The utility model content:
The purpose of this utility model is to provide a kind of novel loss of weight school bag at the deficiencies in the prior art part, it places a soft air bag in school bag, be filled with the inert gas helium of compression in this soft air bag, can utilize the buoyancy of air to alleviate the weight of whole school bag, easy to use, simple in structure.
Technology solution of the present utility model is as follows:
A kind of novel loss of weight school bag comprises the school bag body, and described school bag is body formed a gasbag chamber, is placed with a soft air bag in the described gasbag chamber, is filled with the inert gas helium of compression in the described soft air bag.
Described a kind of novel loss of weight school bag, one charge valve is installed on the air-filled pore of described soft air bag, described charge valve is made of inflation valve body, soft rubber valve inside, and described inflation valve body screw thread is fixed on the air-filled pore of soft air bag, and described soft rubber valve inside tight fit is installed on the inflation valve body.
Described a kind of novel loss of weight school bag is equipped with the sealing ring with described inflation valve seal on the air-filled pore of described soft air bag.
Described a kind of novel loss of weight school bag, on the described soft air bag safety valve is installed, described safety valve is made of valve seat, spool, spring, nut, described valve seat interference fit is installed in the valve opening of soft air bag, the spool matched in clearance is installed in the described valve seat, spring one end active force is on spool, and other end active force is on the nut that is installed on the soft air bag valve opening.
The utility model beneficial effect is:
1) the utility model is by placing soft air bag in the school bag body, be combined in the inert gas helium that is full of compression in the soft air bag, utilize the lighter-than-air principle of helium, can significantly alleviate the weight of whole school bag, under the situation of the equal size of soft air bag, the amount how many bases of weight reduction pour helium decides, and the more weight that alleviate of the helium that charges into many more more, otherwise then little.And the gas that charges into is the inert gas helium, and nonflammable, non-explosive, security is good, and is not dangerous.
2) charge valve that is made of inflation valve body, soft rubber valve inside also is installed on the soft air bag of the present utility model, can inflates soft air bag, the helium that makes soft air bag can replenish loss uses, and then can repeatedly use.
3) on the soft air bag of the present utility model a safety valve is installed also, when can surpass setting value at the gas pressure of the compressed helium in the soft air bag, open venting, soft air bag is carried out pressure release, when preventing that helium pressure that soft air bag charges into is too high or running into the huge external pressure in outside, soft air bag generation explosion, not entail dangers to user's safety.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the utility model structural representation;
The charge valve structural representation of Fig. 2 for installing on the soft air bag;

The specific embodiment:
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
See shown in the accompanying drawing 1～3: a kind of novel loss of weight school bag, comprise school bag body 1, described school bag body 1 forms a gasbag chamber 101, is placed with a soft air bag 2 in the described gasbag chamber 101, is filled with the inert gas helium 3 of compression in the described soft air bag 2.
One charge valve 4 is installed on the air-filled pore of described soft air bag 2, described charge valve 4 is made of inflation valve body 401, soft rubber valve inside 402, described inflation valve body 401 screw threads are fixed on the air-filled pore of soft air bag 2, and described soft rubber valve inside 402 tight fits are installed on the inflation valve body 401.
One safety valve 6 is installed on the described soft air bag 2, described safety valve 6 is made of valve seat 601, spool 602, spring 603, nut 604, described valve seat 601 interference fit are installed in the valve opening of soft air bag 2, spool 602 matched in clearance are installed in the described valve seat 601, spring 603 1 end active forces are on spool 602, and other end active force is on the nut 604 that is installed on soft air bag 2 valve openings.
Operation principle: utilize 3 light principles of air of helium, make the soft air bag 2 of compressed air suits-helium 3 have very big buoyancy, can alleviate the weight of whole school bag.Charge valve 4 is made of inflation valve body 401, soft rubber valve inside 402, utilize inflatable tool to give soft air bag 2 inflations by charge valve 4, soft rubber valve inside 402 opens in inflation, after inflation finishes in soft air bag 2 under the effect of gas pressure, it inwardly shrinks airtight, the discord external world communicates, and principle is similar to bicycle valve core.When the compressed helium in the soft air bag 2 surpassed setup pressure value, the spring force that its interior compressed helium overcomes spring 603 was pushed spool 602 open, makes the helium 3 of compression release a part, and the force value that guarantees the compressed helium in the soft air bag 2 is in safe range.
