Description

A decompression backpack

This creation is related to a backpack technical field, and specifically relates to a decompression backpack.

The backpack is a daily necessity. When people carry the backpack on their shoulders, the shoulder strap is the main load-bearing part of the backpack. Over time, it will easily cause fatigue on the shoulders of the person, which will affect the health of the user. A shoulder strap that is too stiff will cause a heavy load on the person's shoulders and may even be uncomfortable, while a shoulder strap that is too soft will not be strong enough to carry heavy objects.

In order to reduce the pressure on the shoulder of the backpack, the traditional method is generally to install a pair of belts on the lower end of the backpack, and fasten the belt to the waist when backpacking. The method of installing the waist belt can only reduce the shoulder load of the human body to a limited extent; and when the backpack is loaded with heavy objects, the waist belt and the hip bone will produce friction, giving people a sense of discomfort.

At present, there is a better solution: using anti-gravity to reduce pressure to improve the comfort of the user during the backpack process, such as the technical solution disclosed in the patent application file anti-gravity backpack (CN105747477A). The pressure plate, the first elastic band and the length fixing band, during the backpacking process of the user, the backpack generates up and down vibrations, which provides a cushioning effect for the user, which can alleviate the pressure caused by the load being transferred to the user's shoulders. The resilience generated by the belt reduces the effort required by the user and also reduces the weight on the shoulders, so that if the user is placed in an anti-gravity space, the user's comfort is improved, so that the user can walk briskly Effortless.

However, in order to ensure that the elastic belt, the decompression plate, and the fixing belt can work stably, reliably, and safely, such a technical solution must make the connection relationship between the decompression plate, the first elastic belt, the length fixing belt, and the backpack body fixed . However, due to the large difference in the load-bearing of the backpack in different usage environments, when the above components, especially the first elastic band cannot be replaced in different usage environments, it will also cause a bad user experience; When the load exceeds the rated load, the first elastic band will be severely deformed and elongated. At this time, the portion of the backpack body that originally contacts the (human body) back may be lowered. During the backpack process (human body), the back may be improperly applied. Will feel uncomfortable.

In order to solve the technical problem that the existing decompression backpack cannot adapt to a variety of different load usage requirements, the present invention provides a new type of decompression backpack, which can meet different load usage requirements by replacing the decompression element.

In order to achieve the above purpose, a decompression backpack provided by the author includes a backpack body, a decompression plate, a decompression assembly, and two shoulder straps; the decompression plate is provided on the back of the backpack body near the back .

The first end of the telescopic rod is detachably connected to the lower end of the decompression plate, the upper end of the decompression plate is connected to the upper end of the shoulder strap, and the lower end of the shoulder strap is connected to the back of the backpack body Lower connection.

In the above decompression backpack, the case includes two clamps, the inner wall of each clamp protrudes outward to form a slideway, the two slideways are oppositely arranged, and the telescopic rods are located on the two The cavity formed by the slideway can be telescopic up and down.

The two clamps are respectively denoted as a first clamp and a second clamp, the first clamp is fixedly installed at the rear of the backpack body, and the slide rail thereon faces away from the backpack body, and the second clamp is detachable Installed on the first jig.

In the above-mentioned decompression backpack, a base is provided at the bottom of the second end of the telescopic rod, and the base is limited to the chamber formed by the two slideways.

In the above decompression backpack, the top of the first end of the telescopic rod is provided with a groove in the up-down direction, the thickness of the lower end of the decompression plate matches the width of the groove, and the lower end of the decompression plate Removably installed in the groove.

In the above-mentioned decompression backpack, a connection hole for detachably connecting the lower end of the decompression plate and the first end of the telescopic rod is also provided horizontally on the upper part of the telescopic rod.

In the above-mentioned decompression backpack, the upper end of the rear side of the backpack body near the back is also provided with up-and-down through-limiting sleeves, and the elastic pressure band is arranged vertically on the side of the backpack body opposite to the backpack body , The upper end of the elastic band is connected to the upper end of the decompression plate, and the lower end of the elastic band is connected to the lower end of the decompression plate through the limit sleeve.

In the above decompression backpack, the rear part of the backpack body near the back is also provided with positioning parts for restricting the front-back, left-right movement of the decompression plate.

In the above-mentioned decompression backpack, the positioning portion is a pocket with the opening facing upward, and the decompression plate and the decompression assembly are both provided in the pocket and can perform telescopic movement up and down along the pocket.

In the above decompression backpack, the back of the backpack body is further provided with two pads on the side near the back, two pads are provided on both sides of the pocket, and both pads are both Relative to the protrusion of the pocket.

Compared with the prior art, this creation has the following beneficial effects: Since the spring mechanism of the decompression component is detachably provided in the housing, and the first end of the telescopic rod is detachably connected to the lower end of the decompression plate, then the present invention When the decompression backpack needs to be used in other load environments (such as heavy loads), the user can separate the first end of the telescopic rod from the lower end of the decompression plate and the spring mechanism from the shell, and then Then replace the original compression spring set on the telescopic rod with a new compression spring that can withstand the use of other load environments (such as heavy loads), and then reassemble The decompression element and the reassembled decompression element can be reinstalled on the backpack body, so the decompression backpack of the present invention can meet the requirements of different loads by replacing the compression spring in the decompression element.
