Disclosure of Invention
In order to achieve the effect, the invention adopts a combination mode of a spring, a gear, a rack and a connecting belt, one end of the connecting belt is connected with the strap, the other end of the connecting belt is connected with the rack, the rack is pulled by the connecting belt to be meshed with the gear, and the rack reciprocates up and down to drive the gear to rotate correspondingly under the interaction of the spring and the strap, so that the strap and the backpack body form up and down reciprocating motion, and the burden reduction effect is achieved, and the invention is characterized in that:
a gear suspension burden-reducing backpack comprises a spring, a gear, a rack and a connecting belt, wherein the spring, the gear and the rack are installed in a base and a shell, one end of the connecting belt is connected with a strap, the other end of the connecting belt is connected with the rack, the spring and the strap are matched with each other under the action of the heavy edge of the backpack by utilizing the connecting belt to pull the rack and an occlusion gear, the pulling rack reciprocates up and down to drive the gear to rotate correspondingly, so that the strap and a backpack body reciprocate up and down, and the burden-reducing effect is achieved.
The gear is provided with a blade to form a fan, and blows air towards the back to achieve the heat dissipation effect.
The base is fixed on the back panel of the backpack and is fixed by sewing threads, screws and the like.
The base is provided with a slide rail and is used for limiting the running direction of the teeth and preventing deflection.
The shell is provided with a ventilation opening.
The connecting belt is a nylon belt or a steel wire rope.
The technical scheme of the invention is as follows: the combined mode of the spring, the gear, the rack and the connecting belt is adopted, one end of the connecting belt is connected with the strap, the other end of the connecting belt is connected with the rack, the connecting belt is used for pulling the rack to be meshed with the gear, and under the interaction of the spring and the strap, the rack reciprocates up and down to drive the gear to rotate correspondingly, so that the strap and the backpack body reciprocate up and down, and the burden reduction effect is achieved.
The invention has the beneficial effects that: because of the adoption of the gear and rack structure, the roller has stable operation, strong durability and long service life, and because the roller is provided with the blades to form the fan, the fan blows air to the back to achieve the heat dissipation effect.
Drawings
The invention is further illustrated by the following figures and examples,
figure 1 is a rear view of the backpack,
figure 2 is a perspective view of the backpack,
figure 3 is a perspective view of one of the internal structures,
fig. 4 is a second perspective view of the internal structure.
The numbers in the figures are respectively: 1: shoulder pad; 2: carrying out back panel of the backpack; 3: a backpack spine protection strip; 4: a vent; 5: a harness; 6: a backpack body; 7: a connecting belt; 8: a housing; 9: the connecting belt and the braces are fixed; 10: a slide rail; 11: a rack; 12: a base; 13: a blade; 14: a rotating shaft; 15: a gear; 16: a spring.
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. 4, a gear suspension load-reducing backpack is composed of a spring, a gear, a rack and a connecting belt.
As shown in fig. 3, the spring, the gear and the rack are installed in the base and the shell, one end of the connecting belt is connected with the strap, the other end of the connecting belt is connected with the rack, the rack is pulled by the connecting belt and meshed with the gear, the spring and the strap are matched with each other under the action of the heavy edge of the backpack, the rack is pulled to reciprocate up and down to drive the gear to rotate correspondingly, and the strap and the backpack body form reciprocating motion up and down to achieve the effect of burden reduction.
As shown in fig. 4, the gear is provided with a blade forming fan to blow air against the back to achieve a heat dissipation effect.
As shown in fig. 3, the base is fixed on the back panel of the backpack and fixed by sewing or screws.
As shown in fig. 4, the base is provided with a slide rail for limiting the running direction of the teeth and preventing deflection.
As shown in fig. 3, the housing is provided with a vent.
The connecting belt is a nylon belt or a steel wire rope.
As shown in fig. 2, the shoulder straps are limited and fixed by the shoulder pads to prevent the shoulder straps from shaking left and right and separating from the back panel, the shoulder straps extend out of the shoulder strap extension openings, the shoulder straps are not fixedly connected with the back panel, and the shoulder straps can slide up and down along the back panel;
when the backpack body moves downwards, the rack moves upwards, the rack drives the gear to rotate in the forward direction, when the lower dead point is reached, the rack moves to the uppermost spring to be in a tightening state and animal potential to be sent, the rack is driven to move downwards under the action of the spring to move upwards, the rack drives the gear to rotate in the reverse direction, the next cycle is started, and the cycle is repeated to achieve the purpose of reducing the burden.
As shown in FIG. 4, when the fan is formed by arranging the blades on the gear, the fan blows air to the back, so that the effect of reducing the burden can be achieved and the heat dissipation effect can be achieved.
The common backpack can be divided into summer money and winter money, the backpack can be only used for summer money when a blade fan is adopted, if the backpack is used in winter, a tightening belt can be arranged on the shoulder straps to adjust the operation range of the shoulder straps until the shoulder straps cannot move, namely the shoulder straps are fixed with the back part and lose the burden reduction effect, and the backpack cannot drive the fan to rotate when used as a common backpack.
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.
