Description

Backpack harness

Technical Field

The invention relates to a backpack, in particular to a backpack harness for carrying a built-in oxygen supply device of an oxygen cylinder.

Background

At present, according to the investigation of mine accidents in all countries in the world, miners who are injured and die instantly when accidents such as fire disasters and explosions occur only account for a small part of the total number of casualties of the accidents, and most miners are suffocated or poisoned and die because the miners cannot ascend the well or escape from the high-concentration toxic and harmful gas field in time after the fire disasters and the explosions. Therefore, how to provide clean oxygen for survivors after the occurrence of accidents such as fire and explosion, provide necessary survival conditions for the survivors, and prolong the survival time until rescuers arrive becomes an important issue for emergency rescue. The existing built-in oxygen supply device for the oxygen cylinder has small volume and light weight, can conveniently supply oxygen, but has the problems of more parts and difficult carrying.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provides a backpack harness which is simple in structure and convenient to use; the carrying is convenient, and the use is flexible; the volume is small, and no overlarge space is occupied; low production cost and convenient popularization and use.

In order to achieve the purpose, the invention adopts the technical scheme that: the utility model provides a knapsack harness, includes the main package that is used for placing built-in oxygen cylinder and the braces that is connected with the main package, its characterized in that: an upper cover is arranged on the upper portion of the main bag, a hole-shaped outlet used for penetrating through the oxygen pipe is formed in the upper cover, and a three-dimensional bag used for placing the oxygen mask and accessories of the oxygen mask is arranged on the braces.

The upper cover is connected with the main bag through a zipper.

And a heat insulation pad is arranged in the back interlayer of the main bag.

And woven belts are arranged between the lower ends of the straps and the main bag and between the two straps, and the two woven belts are connected through a hasp.

Compared with the prior art, the invention has the following advantages:

(1) simple structure and convenient use. The backpack harness has simple structure, and a user only needs to put the built-in oxygen supply device of the oxygen cylinder into the backpack harness, and then the back of the user is on the back of the user, so the backpack harness is very simple and convenient;

(2) convenient carrying and flexible use. The backpack harness has small volume and light weight, is carried on the back, and is very convenient to carry;

(3) small volume and no occupation of overlarge space. The backpack harness has the same size with a common backpack, has small volume and does not occupy too large space;

(4) low production cost and convenient popularization and use. The production material of the backpack harness is very convenient to produce and purchase, so that the production cost is very low, and the backpack harness is convenient to popularize and use.

The invention is described in further detail below with reference to the figures and examples.

Detailed Description

The backpack harness shown in fig. 1 and 2 comprises a main bag 1 for placing a built-in oxygen bottle and a strap 2 connected with the main bag 1, wherein an upper cover 3 is arranged at the upper part of the main bag 1, a hole-shaped outlet 4 for passing through an oxygen pipe is arranged on the upper cover 3, and a three-dimensional bag 5 for placing an oxygen mask and accessories thereof is arranged on the strap 2.

As shown in fig. 1 and 2, the upper cover 3 is connected to the main bag 1 by a zipper. The upper cover 3 can be opened or closed quickly and conveniently by using the zipper.

As shown in fig. 2, a heat insulation pad is arranged in the back interlayer of the main bag 1. The heat insulation pad can play a heat insulation role on one hand, and can improve the comfort degree of bearing on the other hand.

As shown in fig. 2, a webbing 6 is provided between the lower end of the shoulder strap 2 and the main bag 1 and between the two shoulder straps 2, and the two webbing 6 are connected by a buckle 7.

The working process of the backpack harness of the invention is as follows: when in use, the three-dimensional bag 5 on the harness 2 of the backpack harness is opened, the oxygen mask and the accessories thereof are taken out, the oxygen tube passes through the hole-shaped outlet 4 on the upper cover 3 to connect the oxygen mask with the built-in oxygen bottle arranged in the main bag 1, and the user can take the oxygen mask.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, changes and equivalent structural changes made to the above embodiment according to the technical spirit of the present invention still fall within the protection scope of the technical solution of the present invention.
