Description

Technical Field

[0001] The utility model relates to the field of school bags, in particular to a suspended load-reducing school bag. Background Art

[0002] In order to reduce the weight that students have to carry, various types of weight-reducing backpacks have gradually been launched on the market, which effectively reduce the pressure on the spine when students carry heavy objects. From a mechanical point of view, the pressure generated by the backpack on the human body mainly comes from its gravity. Based on the principles of ergonomics, the weight-reducing effect is achieved by adjusting and optimizing the pressure distribution when the backpack is carried.

[0003] To this end, a load-reducing backpack with patent publication number CN205358650U includes a bag body and shoulder straps located on the back of the bag body, an air cushion is fixed on the inner side of the shoulder straps; a hydrogen bag is connected to the upper part of the bag body; two waist belts are connected to the middle part of the back of the bag body, and a support part is arranged at the lower middle position of the back of the bag body; the load-reducing backpack is simple in design, easy to use, and has a certain load-reducing effect when carried.

[0004] When the backpack is heavy, it fits closely to the user's back. When the user walks or runs quickly, the vibration force generated by the backpack puts pressure on the user's back, affecting the user's rapid movement. In addition, when the backpack is carried, a certain amount of pressure is exerted on the shoulders and waist. Only by improving the decompression of the waist can the effect of reducing the load when the backpack is carried be achieved more evenly. Utility Model Content

[0005] In response to the above problems, a suspended load-reducing backpack is provided. The contour of the back of the backpack is limited by a curved supporting steel frame and a suspended back net, so as to prevent the backpack from sticking too close to the user's back and generating a large pressure force. This solves the problems of the backpack sticking too close to the user's back when it is heavy, and the vibration force generated by the backpack during fast walking and running puts pressure on the user's back, affecting the user's fast movement.

[0006] In order to solve the problems of the prior art, the utility model provides a suspended load-reducing backpack, comprising a backpack body and two widened shoulder straps connected to the backpack, the suspended load-reducing backpack also includes a widened limiting belt fixedly connected to the back of the backpack body, a suspended back net connected to the widened limiting belt and the backpack body and fitted to the back of the user, an arc-surface supporting steel frame snap-fitted between the widened limiting belt, the suspended back net and the backpack body, and a limiting buckle belt adhesively connected to the backpack body to limit the lower end of the arc-surface supporting steel frame, the arc-surface supporting steel frame is bent and fitted to the back of the backpack body to shape the back of the backpack body so that the back of the backpack body is bent but not tightly attached to the back of the user, thereby reducing the pressure on the back when carrying the backpack and not affecting the user's rapid movement when carrying the backpack.

[0007] Preferably, the arc surface supporting steel frame is attached to the back side of the school bag body, and the arc surface supporting steel frame is bent in a direction close to the school bag body.

[0008] Preferably, the arc surface supporting steel frame includes a supporting tube and a limiting tube, and two supporting tubes are symmetrically arranged about the limiting tube, the upper supporting tube is clamped between the widened limiting belt and the backpack body, and the lower supporting tube is clamped between the limiting buckle belt and the backpack body.

[0009] Preferably, the outer part of the arc surface supporting steel frame is clamped and installed with a supporting buckle for expanding and shaping function.

[0010] Preferably, the support buckle is provided with a clamping groove and an arc groove for clamping and assembling with the limiting tube.

[0011] Preferably, the suspended back net is provided with human body protection waist wings for dispersing waist pressure, and the human body protection waist wings include a middle protection wing fixed directly below the suspended back net, and side protection wings are obliquely connected to the left and right sides of the middle protection wing.

[0012] Preferably, a pressure-dissipating adjustment belt for dispersing shoulder pressure is connected between the widened shoulder straps and the backpack body.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The utility model is provided with an arc-surface support steel frame, which is bent and fits on the back of the backpack body to shape the back of the backpack body so that the back of the backpack body is bent but not tightly attached to the back of the user, thereby reducing the pressure on the back when carrying the backpack and not affecting the user's rapid movement when carrying the backpack.

[0015] 2. The utility model is provided with a suspended back net, which fits the back of the user when the backpack is carried. The suspended back net has good air permeability and uniform pressure dispersion. When the user moves in width, the suspended back net can also play a certain buffering effect, thereby reducing the burden of carrying the backpack.

[0016] 3. The utility model is provided with human body protection waist wings, which include middle protection wings and side protection wings. The protection range of the waist is large, and the pressure of the backpack on the waist can be evenly dispersed, thereby improving the load-reducing effect of the backpack.

[0028] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] See also Figure 1-Figure 4 and Figure 8As shown, a suspended load-reducing backpack comprises a backpack body 1 and two widened shoulder straps 2 connected to the backpack, the suspended load-reducing backpack also comprises a widened limiting belt 3 fixedly connected to the back of the backpack body 1, a suspended back net 4 connected to the widened limiting belt 3 and the backpack body 1 and fitted to the back of the user, an arc-surface supporting steel frame 5 snap-fitted between the widened limiting belt 3, the suspended back net 4 and the backpack body 1, and a limiting buckle 6 adhesively connected to the backpack body 1 to limit the lower end of the arc-surface supporting steel frame 5. The suspended back net 4 adopts a suspended mesh surface, which can be deformed according to the back of the human body and can fit the back well in various body postures. The suspended back net 4 has built-in medium and high carbon alloy steel wires to completely arch the back of the backpack, and the back of the backpack is suspended in the air without contact with the body. Compared with the block sponge pad of the traditional backpack, the contact surface is larger and the pressure dispersion is more uniform.

[0030] The backpack body 1 is carried on the body by widening the shoulder straps 2, and the arc-surface supporting steel frame 5 is bent and fits on the back of the backpack body 1, so that a certain gap is generated between the back of the backpack body 1 and the suspended back net 4. The back of the backpack body 1 is not in direct contact with the user's back, and the user's back is in close contact with the suspended back net 4. The suspended back net 4 has good air permeability and produces less pressure on the user's back. At the same time, when the user walks or runs quickly, the vibration force generated by the backpack body 1 can be buffered by the mesh surface of the suspended back net 4 and the steel wire, thereby reducing the pressure on the back and making the backpack easier to carry.

[0031] See also Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, the arc surface support steel frame 5 is attached to the back of the school bag body 1 , and the arc surface support steel frame 5 is bent in a direction close to the school bag body 1 .

[0032] The curved support steel frame 5 bends and shapes the back side of the backpack body 1 to prevent the backpack body 1 from sticking to the user's back when the user carries the backpack, thereby reducing the burden and pressure on the user's back and making it easier for the user to exercise while carrying the backpack. In addition, due to the shaping effect of the curved support steel frame 5 on the back side of the backpack body 1, a certain distance is formed between the backpack body 1 and the suspended back net 4. This distance not only provides ventilation for the user's back during exercise, but also provides a certain space for the elastic deformation of the suspended back net 4, which can effectively buffer the vibration force generated by the user during exercise and improve the burden-reducing effect of the backpack.

[0033] See also Figure 6 As shown, the arc support steel frame 5 includes a support tube 51 and a limiting tube 52. Two support tubes 51 are symmetrically arranged about the limiting tube 52. The upper support tube 51 is clamped between the widened limiting belt 3 and the backpack body 1, and the lower support tube 51 is clamped between the limiting buckle belt 6 and the backpack body 1.

[0034] The upper and lower support tubes 51 in the arc surface support steel frame 5 are snap-fitted and installed at the upper and lower positions on the back of the school bag body 1 . The snap-fit ​​structure can limit the range of bending and shaping of the back of the school bag body 1 by the arc surface support steel frame 5 .

[0035] See also Figure 6 and Figure 7 As shown, the outer part of the arc surface support steel frame 5 is clamped and installed with a support buckle 7 for expanding and shaping.

[0036] When the arc surface support steel frame 5 is in its original state, the left and right limit tubes 52 are relatively close, and the support buckle 7 is snap-fitted and assembled on the arc surface support steel frame 5, and the left and right limit tubes 52 are stretched outward. The entire arc surface support steel frame 5 is tightened and supported on the back of the schoolbag body 1 under the influence of the stretching force, thereby improving its bending and shaping effect.

[0037] See also Figure 6 and Figure 7 As shown, the support buckle 7 is provided with a slot 71 and an arc slot 72 for engaging with the limiting tube 52 . The end of the support buckle 7 that fits the back of the backpack body 1 is in an arc-shaped structure, which is compatible with the curvature of the arc-surface support steel frame 5 .

[0038] The limiting tubes 52 in the arc surface supporting steel frame 5 are engaged in the clamping grooves 71 and the arc grooves 72 on the supporting buckle 7 to limit the positions where the two limiting tubes 52 are stretched apart.

[0039] See also Figure 2 and Figure 5 As shown, the suspended back net 4 is provided with a human body protection waist wing 41 for dispersing the waist pressure, and the human body protection waist wing 41 comprises a middle protection wing 411 fixed directly below the suspended back net 4, and the left and right sides of the middle protection wing 411 are obliquely connected with side protection wings 412; the middle protection wing 411 and the side protection wing 412 both adopt enlarged and thickened waist sponge pads to more evenly disperse the pressure of the backpack on the waist.

[0040] When the backpack body 1 is carried on the body, the middle protection wing 411 fits the user's waist, and the two side protection wings 412 fit the two sides of the user's waist respectively. The support and protection of the user's waist has a wider range and is more effective in sharing the waist pressure. The side protection wings 412 are arc-shaped, which is adapted to the curvature of the human waist and effectively protects the user's waist.

[0041] See also Figure 1 and Figure 2 As shown, a pressure-dispersing adjustment belt 21 for dispersing shoulder pressure is connected between the widened shoulder strap 2 and the backpack body 1 , and the pressure-dispersing adjustment belt 21 is connected by a cloth belt and a buckle to adjust the length.

[0042] When the user carries the widened shoulder strap 2 on his body, most of the pressure of an ordinary school bag is transmitted to the user's shoulder through the shoulder strap, which generates relatively large pressure on the shoulder. After carrying the school bag, the user adjusts the length of the pressure-releasing adjustment belt 21 connected between the widened shoulder strap 2 and the school bag body 1 to prevent the school bag from turning over and falling due to being too heavy, and disperses part of the pressure to the waist and back, so that the shoulders are less stressed and the pressure of the school bag on the user's shoulders is better shared.

[0043] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
