Description

Technical Field

[0001] The utility model relates to the technical field of burden-reducing schoolbags, in particular to a spinal cord protection and burden-reducing schoolbag. Background Art

[0002] A schoolbag refers to a bag made of cloth, leather, etc., which students use to carry textbooks and stationery. According to different materials, it can be divided into canvas bags, Oxford cloth bags, and nylon cloth bags. With the change of consumers' tastes and demands, the materials of schoolbags are more diversified. Existing backpacks lack a spinal cord protection mechanism.

[0003] After retrieval, a spinal cord protection schoolbag (authorization announcement number: CN 221382795 U) "comprises a schoolbag main body, a handbag is sewn on the upper surface of the schoolbag main body, a sub-bag is sewn on the back of the schoolbag main body, two shoulder straps are sewn on the front of the schoolbag main body, adjustment buckles are arranged on the shoulder straps, waist and abdomen straps are sewn on both sides of the back of the schoolbag main body, and one end of each of the two waist and abdomen straps extends to the front of the schoolbag main body. This spinal cord protection schoolbag can be connected by two elastic bands to limit books in the schoolbag main body, prevent the schoolbag from shaking when the student carries the schoolbag, and increase the pressure of the schoolbag shoulder straps on the student. By arranging a support plate inside the schoolbag main body, it is convenient for the whole front of the schoolbag main body to contact the student's back, improving the back stress area when the student carries the backpack. The front of the schoolbag main body contacts the student's back through a foam board, and the foam board has good elasticity to prevent the hard support plate from directly contacting the student's back and causing physical damage to the student."

[0004] According to the above related technologies, the applicant believes that there is no connection between the two backpack shoulder straps in the above technologies, and there is a lack of support on the back of the backpack, so the weight of the backpack cannot be evenly distributed, and thus a good spinal cord protection effect cannot be formed. In view of the above problems, we have introduced a spinal cord protection and burden-reducing schoolbag. Content of the Utility Model

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Usually, the components of the embodiments of the present application described and marked in the attached drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the attached drawings is not intended to limit the scope of the present application that is required to be protected, but only represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of the present application.

[0022] Referring to Figure 1 - Figure 4 , a spinal protection and load reduction schoolbag includes a main backpack 1. A secondary backpack 3 is fixedly connected to the outside of the main backpack 1. Backpack shoulder straps 10 are symmetrically and fixedly connected to the back of the main backpack 1. A spinal protection mechanism is provided on the outside of the main backpack 1. The spinal protection mechanism includes a spinal protection belt 41. The spinal protection belt 41 is fixedly connected to the back of the main backpack 1. The spinal protection belt 41 is fixedly connected to the two backpack shoulder straps 10. A first supporting block 42 is fixedly connected to the back of the main backpack 1. A second supporting block 43 is fixedly connected to the back of the main backpack 1 and is located below the first supporting block 42. A ventilation slot 44 is opened inside the second supporting block 43. A protection block 45 is fixedly connected to the bottom of the second supporting block 43. The top of the protection block 45 is fixedly connected to the bottom of the second supporting block 43.

[0023] In the above technical solution, considering the problem that there is a lack of connection between the two backpack shoulder straps, the back of the backpack lacks support, and the weight of the backpack cannot be evenly distributed, resulting in a poor spinal protection effect. To solve such problems, the specific operations are as follows:

[0024] Refer to Figure 1 - Figure 4 In a preferred embodiment, during actual use, the student carries the main backpack 1 on the back, and the weight of the main backpack 1 fits against the student's back. The first supporting block 42 and the second supporting block 43 support the student's back. Through the provided spinal protection mechanism, the spinal protection belt 41, the first supporting block 42, and the second supporting block 43 can evenly distribute the gravity of the backpack, and the protection block 45 can assist in supporting the weight of the main backpack 1. At the same time, a gap can be formed between the main backpack 1 and the student's back to ventilate and dissipate heat from the student's back.

[0025] Refer to Figure 1 - Figure 4 In a preferred embodiment, the outer side of the secondary backpack 3 is fixedly connected with first magic tapes 5 at equal intervals. The outer side of the first magic tapes 5 is provided with second magic tapes 6, and the outer side of the second magic tapes 6 is fixedly connected with a reflective strip 7. Both sides of the bottom of the main backpack 1 are symmetrically and fixedly connected with support columns 8. The bottom of the support columns 8 is fixedly connected with feet 9, and the feet 9 are made of rubber material. Heat dissipation holes 11 are equally spaced inside both backpack straps 10. The top of the main backpack 1 is fixedly connected with a lifting handle 2. The outer side of the lifting handle 2 is fixedly connected with a rubber pad for anti-slip. Through the provided reflective strip 7, after school at night, it can warn the vehicles behind to avoid collision accidents caused by dim light. At the same time, the cooperation between the first magic tape 5 and the second magic tape 6 can replace the old reflective strip 7. Through the provided feet 9, the main backpack 1 can be supported to prevent the main backpack 1 from being directly placed on the ground and being polluted by dust and sewage. Through the provided rubber pad, the friction force can be increased.

[0026] Working principle: During actual use, the student carries the main backpack 1 on the back, and the weight of the main backpack 1 fits against the student's back. The first supporting block 42 and the second supporting block 43 support the student's back. The spinal protection belt 41, the first supporting block 42, and the second supporting block 43 can evenly distribute the gravity of the backpack, and the protection block 45 can assist in supporting the weight of the main backpack 1. At the same time, a gap can be formed between the main backpack 1 and the student's back to ventilate and dissipate heat from the student's back. Through the provided reflective strip 7, after school at night, it can warn the vehicles behind to avoid collision accidents caused by dim light. At the same time, the cooperation between the first magic tape 5 and the second magic tape 6 can replace the old reflective strip 7. Through the provided feet 9, the main backpack 1 can be supported to prevent the main backpack 1 from being directly placed on the ground and being polluted by dust and sewage.
