Problems solved by technology

During the process of the airbag being inflated and abutted against the inner wall of the van body until the airbag is completely attached to the inner wall of the van body, due to the large volume of the airbag, and the operator can only observe When the airbag faces the operator's side, the operator cannot judge the degree of fit between the airbag and the inner wall of the van, which creates a problem: at the end of inflation, the airbag and the van The inner wall of the car body is not fully fitted, resulting in poor heat preservation and heat insulation effects of the airbag

Embodiment 1

[0036] Such as figure 1 with figure 2 As shown, the heat insulation airbag used on the van is composed of a body 1 with a closed air chamber 1a, and the body 1 is in the shape of a rectangular plate when inflated. Such as figure 2 As shown, the body 1 is provided with an air nozzle 2 communicating with the inflation cavity 1 a, and in actual use, the body 1 is inflated or deflated through the air nozzle 2 .

[0037] Specifically, as image 3 with Figure 4 As shown, between the front side 1e of the body 1 and the rear side 1e of the body 1, there is a strip-shaped flexible piece 3, that is, the flexible piece is located in the inflatable cavity 1a, there are multiple flexible pieces 3, and multiple flexible pieces 3 are arranged parallel to each other. The lengths of each flexible piece 3 are approximately equal, and the two ends of each flexible piece 3 are respectively fixed to the front side 1d of the main body 1 and the rear side 1e of the main body 1 . In this exa...

Embodiment 2

[0043] The structure and principle of this second embodiment are basically the same as that of the first embodiment, except that the flexible part 3 is a leather strip, and the two ends of the leather strip are fixedly connected with the two connecting pieces 1b respectively, and the leather strip is used as the flexible part 3, and the leather strip It also has the advantage of not being easily deformed, and can effectively ensure that the shape of each expansion of the airbag is a rectangular plate, which improves the heat insulation and heat preservation effects of the heat-insulating airbag.

Embodiment 3

[0045] The structure and principle of the third embodiment are basically the same as those of the first embodiment, the difference is that: Figure 4 with Figure 5 As shown, a Velcro 5 and a handle 6 are fixedly attached to the outer wall of the connecting piece 1b. The handle 6 is made of flexible material, and the flexible material can be leather, cowhide and the like. When the airbag is not in use, the entire airbag can be rolled up into a columnar shape, and the fluffy surface on the Velcro 5 and the hook-shaped surface are bonded together to keep the rolled up airbag in a columnar shape, which improves the convenience of carrying the airbag sex. By providing the handle 6, it is convenient for the user to exert force on the airbag, so as to facilitate the detachment of the airbag from the van compartment or to facilitate the carrying of the airbag.

Abstract

The invention provides a heat-insulating airbag for a van, which belongs to the technical field of machinery. It solves the problem of poor heat insulation effect of the existing heat insulation airbags. The heat-insulating airbag used on the van includes a body with a closed air chamber, and the body is provided with an air nozzle communicating with the air chamber. It is characterized in that the body is in the shape of a rectangular plate Shape, the said inflatable cavity is provided with a plurality of flexible parts of approximately equal length, and the plurality of flexible parts are parallel to each other, and the two ends of the flexible parts are connected with the front side of the body and the The rear side is fixed. The heat insulating air bag used on the van has the advantages of good heat insulation and heat preservation effects.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a heat-insulating air bag, in particular to a heat-insulating air bag used on a van. Background technique [0002] The refrigerated van is mainly used to transport goods that require temperature, such as items that need to be kept fresh, and the refrigerated van can adjust and set different temperatures to keep the goods fresh to achieve the purpose of short-term preservation of the transported goods. At present, the existing refrigerated vans are basically equipped with airbags in the compartment, and the airbags are inflated against the inner sidewall of the compartment of the refrigerated van to form a seal, so that a seal is formed between the airbag and the inner sidewall of the compartment. Insulation cavity, the goods that need to be kept fresh are placed in the insulation cavity, so as to reduce the heat exchange between the insulation cavity and the external environment ...
