Description
Technical Field
The invention relates to an adjustable shoulder strap connecting device, belongs to the field of bags and bags, and is used for connecting a shoulder strap with a backpack.
Background
At present, straps of a common backpack are fixed on the back panel of the backpack, the width and the angle of the straps are not adjustable, but the backpack is uncomfortable if the straps are not adjusted due to different body shapes, for example, when a person with wide shoulders carries the backpack, the distance between the straps is too small, and the straps clamp the neck, so that the person is difficult to feel; for example, when a person carries a backpack with narrow shoulders, the distance between the straps is too large, and the straps are easy to slip off; to make people of different body shapes more comfortable, the corresponding angle and width adjustment needs to be made according to the height and shoulder width of the people.
Disclosure of Invention
The invention aims to provide an adjustable shoulder strap connecting device which is small, simple and convenient to operate. In order to solve the defects, the invention adopts the following technical scheme.
The backpack strap connecting device is composed of rotating wheels and a shell, the rotating wheels are symmetrically arranged, the shell is arranged outside the rotating wheels, a rotating shaft is arranged on the shell, the rotating wheels are installed on the rotating shaft and can rotate around the rotating shaft, a buckle for connecting straps is arranged on the rotating wheels, and the backpack straps can be connected to the buckle through a braid.
The rotating wheels are arranged in a gear shape, and the two rotating wheels are meshed with each other, so that the rotating wheels rotate synchronously when rotating, and the straps can be kept symmetrical all the time.
The technical scheme of the invention is as follows: the backpack straps are connected to the rotating wheel by adopting the rotatable gear type rotating wheel, and the width and the angle of the straps are adjusted by rotating the rotating wheel.
The invention has the beneficial effects that: simple structure, convenient to use, it is with low costs, adaptable different bodily forms's people use, because the runner is movable, can be rotatory round the pivot, the runner can automatic adjustment angle and width, need not the manual regulation of going.
Drawings
The invention is further illustrated by the following figures and examples:
FIG. 1 is a schematic view of an adjustable brace connector,
figure 2 is a front view of the adjustable harness connector,
FIG. 3 is a front view of the internal structure of the adjustable harness connector,
FIG. 4 is a perspective view of the internal structure of the adjustable harness connector.
The numbers in the figures are respectively: 1: a left wheel of the brace connecting device; 2: a buckle connected with the strap; 3: a harness connector housing; 4: a strap connecting device right wheel; 5: a rotating shaft; 6: a gear; 7: carrying out back panel of the backpack; 8: a spine protection cushion; 9: the backpack has straps.
Detailed Description
Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. These exemplary embodiments are provided so that those skilled in the art can clearly understand the present invention and can implement the present invention according to the description herein. The drawings and detailed description are not intended to limit the invention, which is defined by the appended claims.
As shown in fig. 1, the adjustable shoulder strap connecting device is fixed on the back panel of the backpack and can be fixed by sewing or riveting, and a spine protection cushion is additionally covered on the adjustable shoulder strap connecting device, so that the shoulder strap connecting device can protect the spine and is more comfortable to carry;
when people with different shapes carry the backpack, the rotating wheel of the backpack buckle can rotate around the rotating shaft under the action of gravity due to different shoulder widths, so that the width and the angle can be automatically adjusted;
as shown in fig. 3, when the rotating wheel rotates outwards, the width between the two straps will increase, which is suitable for people with wider body shape;
when the rotating wheel rotates inwards, the width between the two straps is reduced, and the shoulder strap is suitable for people with narrow body shapes;
meanwhile, due to the rotation of the rotating wheel, the included angle between the strap plane and the rotating shaft can be changed, and the angle can be adjusted while the width is adjusted, so that the strap can automatically adapt to different body shapes;
as shown in figure 3, the two wheels are arranged in such a way that the gears are meshed with each other, so that the two wheels can always rotate synchronously when rotating, and the straps can always keep symmetry.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention.
