Description

Technical Field

[0001] The utility model relates to the technical field of backpacks, in particular to a backpack with a sweat-proof back collar. Background Art

[0002] In daily office, study and travel activities, in order to facilitate the carrying of office supplies, school tools, clothes and other items, a backpack is usually needed. The advantage is that when carrying heavier things, the burden on the shoulders is relatively small, so it is suitable for people to use. However, due to its own size, the backpack will cover the back of the human body most of the time, which can easily cause sweating on the back of people in hot weather or areas, affecting people's use effect.

[0003] According to the disclosed backpack back attachment with air diversion, anti-stuffiness, moisture-proof, sweat-proof, weight reduction and hunchback prevention (publication number: CN213587667U), in the above application, nine raised blocks are arranged on the back of the backpack and are distributed oppositely according to the shape of the bones of the human back. The contact surface between the two has a good air diversion effect, so as to achieve a good fit on the back of the user.

[0004] However, in actual use of the above-mentioned device, although there is a certain gap between the backpack and the back of the human body, which is conducive to air circulation, the weight of the backpack itself will still cause the backpack to fall during outdoor sports and long-distance travel, eventually causing the bottom of the backpack to constantly touch the waist and back of the human body, which not only affects people's walking, but the continuous contact will also affect the ventilation and perspiration effect of the human back. In view of this, we propose a backpack with a sweat-proof back collar. Utility Model Content

DETAILED DESCRIPTION

[0024] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a backpack with a sweat-proof back collar, comprising a backpack body 1, a shoulder strap 2 is movably installed on the outer wall of the backpack body 1, a support assembly 3 is arranged on the outer wall of the backpack body 1, and the support assembly 3 includes a vertical positioning belt 31, a horizontal positioning belt 32, a fixing button 1 33, an arc-shaped support block 34, a fixing button 2 35, a rotating rod 36, an arc-shaped pad 37, a magnetic strip 38, an adjusting bolt 39, a mounting plate 310 and a spiral spring 311.

[0025] In one embodiment of the utility model, a vertical positioning belt 31 is fixedly installed on the outer wall of the backpack body 1, a transverse positioning belt 32 is movably installed on the inner surface of the vertical positioning belt 31, a fixing button 1 33 is fixedly installed on the end side wall of the transverse positioning belt 32, an arc-shaped support block 34 is movably installed on the side wall of the transverse positioning belt 32, a fixing button 2 35 is fixedly installed on the side wall of the arc-shaped support block 34, a rotating rod 36 is rotatably installed on the inner wall of the arc-shaped support block 34, a curved pad 37 is passed through the rotating rod 36, and the curved pad 37 is fixedly connected to the rotating rod 36, a magnetic strip 38 is fixedly installed on the side wall of the curved pad 37, an adjusting bolt 39 is threadedly installed on the inner wall of the arc-shaped support block 34, the adjusting bolt 39 passes through the mounting plate 310, and the mounting plate 310 is fixedly connected to the adjusting bolt 39, and a volute spring 311 is fixedly connected to the side wall of the mounting plate 310.

[0026] Furthermore, the support assembly 3 is arranged at the bottom of the side of the backpack body 1, and the support assembly 3 and the shoulder strap 2 are arranged on the same side of the backpack body 1, so that the support assembly 3 can support the user's waist and back. At the same time, there are two groups of vertical positioning belts 31, and the two groups of vertical positioning belts 31 are symmetrically arranged with the vertical central axis of the backpack body 1 as the symmetry axis, so that the horizontal positioning belt 32 can be adjusted between the two groups of vertical positioning belts 31. In addition, a plurality of rectangular holes are opened on the inner walls of the vertical positioning belts 31 and the horizontal positioning belts 32, and the vertical positioning belts 31 and the horizontal positioning belts 32 are connected to the vertical positioning belts 31 and the horizontal positioning belts 32. The positioning belts 32 are all made of stretch-resistant textile fabrics, and the rectangular holes are matched with the fixing buttons 1 33 and 2 35, so that the user can adjust the position of the transverse positioning belt 32 and the arc-shaped support block 34 according to actual needs (such as body shape, height, etc.). Specifically, the outer wall of the arc-shaped support block 34 on the side close to the vertical central axis of the backpack body is set to an arc-shaped surface, and a sponge pad is provided on the arc-shaped surface, so that the arc-shaped support block 34 can better adapt to the user's waist curve. At the same time, the setting of the sponge pad can avoid causing discomfort to the user and improve the comfort of use of the device.

[0027] In addition, a swing groove is provided on the inner wall of one side of the arc surface of the arc support block 34, and the height of the swing groove is adapted to the arc pad 37, so that the arc pad 37 can rotate on the inner wall of the swing groove with the rotating rod 36 as the rotation center. At the same time, the edges of the arc pad 37 are rounded, and the arc pad 37 is made of rubber material, so as to improve the comfort of the arc pad 37 when it contacts the user's waist and back. Furthermore, the magnetic strip 38 is arranged on the side of the arc pad 37 close to the inner wall of the swing groove, and the inner wall of the swing groove is provided with a magnetic sheet with the same magnetic property as the magnetic strip 38, so that there is always a repulsive force between the magnetic strip 38 and the magnetic sheet, so as to force the arc pad 37 to always rotate with the rotating rod 36 as the rotation axis toward the side away from the inner wall of the swing groove, so as to better fit the user's waist and back.

[0028] Specifically, an expansion slot is provided at the end of the adjusting bolt 39, and the end of the rotating rod 36 is rotatably connected to the bottom inner wall of the expansion slot, and the threaded connection between the adjusting bolt 39 and the arc support block 34 makes the adjusting bolt 39 have a self-locking effect. When the adjusting mounting plate 310 is rotated and is not subject to external force, it can be ensured that the adjusting bolt 39, the mounting plate 310 and the arc support block 34 will remain in a relatively static state. At the same time, the volute spring 311 is sleeved on the arc outer wall of the rotating rod 36, so that the volute spring 311 always gives the rotating rod 36 a movement trend to drive the arc pad 37 to rotate in the opposite direction to achieve reset when the rotating rod 36 rotates. Furthermore, the number of adjusting bolts 39, mounting plate 310 and volute spring 311 is set in two groups, and the two groups of adjusting bolts 39, mounting plate 310 and volute spring 311 are mirror-imaged on the upper and lower sides of the horizontal central axis of the arc support block 34, so that the adjustment of the arc pad 37 is more stable and flexible.

[0029] In the embodiment of the utility model, the bottom of the arc-shaped support block 34 is provided with an attachment component 4, and the attachment component 4 includes an arc-shaped airbag 41. The arc-shaped airbag 41 is fixedly installed on the lower surface of the arc-shaped support block 34, and a plurality of arc-shaped grooves 42 are provided on the arc-shaped outer wall at the bottom of the arc-shaped airbag 41. Specifically, the arc-shaped airbag 41 is arranged at the bottom edge of the arc-shaped surface of the arc-shaped support block 34, so that the bottom of the arc-shaped support block 34 has a convex airbag, so that the position where the arc-shaped support block 34 contacts the user's waist and back has a buffer portion, and at the same time, the curvature of the arc-shaped airbag 41 is consistent with the curvature of the arc-shaped support block 34. The curvature of the arc surface is the same, and the interior of the arc airbag 41 is filled with inert gas, so as to avoid a large change in the volume of the arc airbag 41 itself when the temperature of the external use environment changes, so that the arc airbag 41 can always form a buffer protection between the arc support block 34 and the patient's waist and back. In addition, the arc groove 42 is arranged on the bottom surface of the arc airbag 41, so that when the arc airbag 41 is used in the backpack body 1, the arc support block 34 and the patient's body will not be greatly offset due to external bumps or shaking, affecting the stable support effect of the support component 3.

[0030] In the utility model, when in use, the user adjusts the specific positions of the fixing button 1 33 and the fixing button 2 35 on the vertical positioning belt 31 and the horizontal positioning belt 32 respectively, thereby adjusting the relative position of the arc-shaped support block 34 on the side of the backpack body 1 to meet the needs of users of different heights and body shapes. After that, the user wears the shoulder strap 2 and carries the backpack body 1 on the back. At this time, the arc-shaped support block 34 fits the user's waist and back. At the same time, the arc-shaped airbag 41 is arranged at the bottom of the arc-shaped support block 34 as an intermediate buffer to ensure that the position of the arc-shaped support block 34 will not be offset, thereby avoiding the backpack body 1 from causing damage to the user's waist and back during exercise.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
