Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

A draw-bar box with an internal buffer device is shown in figure 1 and comprises a box body 1 and a box cover 11 for closing an opening of the box body 1, wherein a buffer mechanism 2 is connected to the box body 1, and the buffer mechanism 2 comprises a first air bag 21 arranged in the box body 1, a second air bag 22 adhered to the box cover 11 and an inflator 23 for inflating. The first air bag 21 is adhered to five side walls of the box body 1, the first air bag and the second air bag 22 are connected with one-way valves 24 respectively, the one-way valves 24 are communicated towards inner cavities of the first air bag 21 and the second air bag 22 respectively, and an air outlet of the inflator 23 is connected with the one-way valves 24 respectively. After the articles are placed in the box body 1, the inflator 23 is used for inflating towards the first air bag 21 and the second air bag 22, the first air bag 21 and the second air bag 22 are expanded, then the box cover 11 is connected with the box body 1, the first air bag 21 and the second air bag 22 are abutted to the articles, the positions of the articles are fixed, collision among the articles in the box body 1 is reduced when the draw-bar box vibrates, and damage to the articles is reduced.

As shown in fig. 1, since contact between adjacent articles is still generated when the position of the article is defined using the buffer mechanism 2, collision between the adjacent articles is still generated. Therefore, a plurality of buffer strips 25 communicated with the inner cavity of the second air bag 22 are integrally formed on the side wall of the opening of the second air bag 22, after articles are placed in the box body 1, the buffer strips 25 positioned at the contact positions of the two articles are placed between the two articles, so that the buffer strips 25 and the second air bag 22 are tightly attached, and at the moment, when the second air bag 22 is inflated, air is filled in the buffer strips 25 to separate adjacent articles, so that collision cannot be generated between the adjacent articles.

As shown in FIG. 2, as the air within second bladder 22 compresses, the adjacent articles may exert pressure on cushioning strip 25 during movement of the luggage, and the air within cushioning strip 25 may be forced into second bladder 22, causing cushioning strip 25 to fail to prevent contact with the adjacent articles. Therefore, the buffer strips 25 are all connected with the limiting mechanisms 3 for limiting air flow, and the limiting mechanisms 3 comprise fixing rods 31 and limiting rods 32 connected with the buffer strips 25. One end of the fixing rod 31 is hinged with one end of the limiting rod 32, and the buffer strip 25 is arranged between the adjacent fixing rod 31 and the limiting rod 32. The position that the lateral wall that dead lever 31 is close to gag lever post 32 keeps away from its pin joint has run through and is the connecting hole 311 that is the rectangle, and the position integrated into one piece that the gag lever post 32 is close to the lateral wall of dead lever 31 and keeps away from its pin joint has the connecting rod 321 that is the rectangle, and connecting rod 321 can pass in the connecting hole 311. The connecting rod 321 is away from the end face of the hinge axis of the limiting rod 32 and is integrally formed with a limiting block 322, and when the limiting rod 32 and the fixing rod 31 are close to each other and abut against each other, the end face of the limiting block 322 close to the limiting rod 32 can abut against the end face of the fixing rod 31 away from the limiting rod 32. After the articles are placed in the box body 1, the inflator 23 is used for inflating the buffering strip 25, then the limiting mechanism 3 is used for closing a connecting channel between the buffering strip 25 and the second air bag 22, so that the air in the buffering strip 25 cannot flow, adjacent articles are divided, and the articles cannot collide with each other.

As shown in fig. 2, when the relative positions of the fixing rod 31 and the limiting rod 32 are limited by the limiting block 322, the limiting block 322 needs to pass through the connecting hole 311, and at this time, the position of the limiting block 322 needs to be manually moved, so that the steps of using the limiting mechanism 3 are increased. Therefore, the end surface of the limiting block 322, which is far away from the connecting rod 321, is provided with a wedge surface 323, and one end of the wedge surface 323, which is far away from the limiting rod 32, inclines towards the connecting rod 321, and can be abutted against the edge at the opening of the connecting hole 311. When the limiting block 322 passes through the connecting hole 311, the wedge-shaped surface 323 is used for guiding the movement of the limiting block 322, so that the position of the limiting block 322 does not need to be moved manually, and the using process of the limiting mechanism 3 is more convenient.

In order that the limiting mechanism 3 does not separate from the buffer strip 25 when the fixing rod 31 and the limiting rod 32 are separated from each other in the opposite direction, as shown in fig. 2, two connecting bands 251 are adhered to the side walls of the buffer strip 25, and the two connecting bands 251 are respectively located at two sides of the buffer strip 25 and are respectively adhered to the end surfaces of the fixing rod 31 and the limiting rod 32, which are close to each other. The position-limiting rod 32 and the fixing rod 31 are connected with the buffer strip 25 by the connecting band 251, so that the position of the position-limiting mechanism 3 is not changed when the position-limiting mechanism is not used, and the position-limiting mechanism can be directly used when the position-limiting mechanism is required to be used.

As shown in fig. 2, since the position-limiting mechanism 3 contacts with the surface of the article when in use, the article and the position-limiting mechanism 3 move relatively to each other, so that scratches are generated on the surface of the article. Therefore, the buffer strip 25 is sleeved with the protection ring 252, and the protection ring 252 is adhered to the side wall of the buffer strip 25 and is positioned on the side of the limiting mechanism 3 far away from the second air bag 22. The end face of the protection ring 252 close to the limiting mechanism 3 is adhered with a buffer layer 253, the buffer layer 253 can cover the limiting mechanism 3, and the buffer layer 253 is made of sponge. The guard ring 252 and the buffer layer 253 prevent the limiting mechanism 3 from directly contacting the article, so that the surface of the article is not scratched.

As shown in fig. 1, when the bag is separated from the cover 11, the bag is inflated into the first airbag 21 and the second airbag 22, and at this time, it is impossible to determine whether or not the pressure in the first airbag 21 and the second airbag 22 can determine the position of the article. Thus, the two check valves 24 are closed through the cover 11 and the tank 1, and the pump 23 is bolted to the outer side wall of the tank 1. After the article is placed in the luggage, the first air bag 21 and the second air bag 22 are inflated by the inflator 23, and whether the inflation needs to be continued is determined according to the degree of a pressure gauge connected to the inflator 23, so that the first air bag 21 and the second air bag 22 can limit the position of the article.

As shown in fig. 1, since the inflator 23 is disposed outside the box body 1, the air outlet pipe of the inflator 23 may shake continuously when the draw-bar box is moved, which affects the movement of the draw-bar box. Therefore, the side wall of the box body 1 connected with the inflator 23 is connected with the buckle 13 through the bolt, and the air outlet pipe of the inflator 23 is clamped with the buckle 13. Utilize buckle 13 to inject the position of inflater 23 air-out pipe to the position of inflater 23 air-out pipe can not change when the draw-bar box removes, thereby makes the removal process of draw-bar box more smooth.

The working principle is as follows:

The article is placed in the box body 1, then the buffer strips 25 are placed between adjacent articles, the limiting mechanism 3 is used for closing the passage of the buffer strips 25 attached to the second air bag 22, the inflator 23 is used for inflating the second air bag 22 and the buffer strips 25, then the limiting mechanism 3 is used for sealing the passage of the buffer strips 25 filled with air, then the air in the second air bag 22 is discharged through the one-way valve 24, the box body 1 is connected with the box cover 11, the inflator 23 is used for respectively filling air into the first air bag 21 and the second air bag 22, the inflation is stopped when the pressure gauge of the inflator 23 reaches 0.3 MPa, and at the moment, the fixation of the article in the pull rod box is completed.

The specific embodiments are only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiments without inventive contribution as required after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
