Abstract

The utility model relates to a knapsack shoulder protecting belt which is provided with an inflatable air bag in the shoulder protecting belt. An air nozzle which is used for inflating the air bag is arranged on the shoulder protecting belt. Because of the arrangement of the inflatable air bag in the shoulder protecting belt of the utility model, the shoulder protecting belt has a soft buffer function only by filling air to the air bag during use. The shoulder protecting belt can not occupy excessive space after releasing the air when the knapsack is collected and not used.

Description

The knapsack shoulder shield

Technical field

The utility model relates to a kind of knapsack, refers in particular to a kind of knapsack shoulder shield.

Background technology

Existing knapsack; no matter be single shoulder knapsack or backpack; on backpack strip, be provided with shoulder shield more, be mostly in this shoulder shield to add thicker cavernous body, make it when contact people's shoulder; the effect of the soft shoulder protector of tool; making the user hold in the process not at the permanent back of the body can tired pain, and this shoulder shield is stronger to the protective effect of people's shoulder, and cavernous body is to be provided with thicklyer; therefore fold the not time spent at knapsack, it is its weak point that the knapsack shoulder shield occupies the space more.

The utility model content

The purpose of this utility model provides a kind of knapsack shoulder shield, and it in use has the better protect effect to people's shoulder, does not take up space again when folding simultaneously.

For achieving the above object, solution of the present utility model is:

The knapsack shoulder shield, it is to be provided with inflatable air bag in shoulder shield inside, shoulder shield is provided with the valve of inflating in the air bag.

Valve on this air bag is a check valve.

After adopting such scheme, because the setting of air bag in the shoulder shield of the present utility model, in use, only need air bag is full of, shoulder shield just has soft cushioning effect, and places the not time spent at knapsack, gas is emitted, and shoulder shield can not take too much space again.

The specific embodiment

As shown in Figure 1, 2; the utility model knapsack shoulder shield 1; be within it portion be provided with can inflatable air bag 2; the Yi Jiaochu of knapsack shoulder shield 1 is provided with the valve 3 that is connected with air bag 2; gas is by this valve 3 gas to be full of in the air bag 2 in the shoulder shield 1; valve 3 is sealed, shoulder shield 1 just becomes a pad with soft buffering again, and its shoulder to people has good protective effect.

As shown in Figure 3, air bag 2 in this shoulder shield 1 is to be made of highdensity cavernous body 21, and the valve that is provided with on the cavernous body 21 is a check valve 4 therewith, cooperate shown in Figure 4, this check valve 4 is by valve seat 41, spool 42 and spring 43 are formed, valve seat 41 middle parts are a through hole 411, in the through hole 411, the outside is respectively equipped with boss 412,413, and the top of spool 42 is the bigger bulb of a diameter 421, it can be blocked the inner of through hole 411, and the position of the boss 413 of the close through hole 411 of spool 42 is provided with catch 422, spring 43 is to be nested with on spool 42, the one end is to hold on boss 412, and the other end is to hold catch 422 and the outer end of through hole 411 is blocked, and the tail end of spool 42 is to convexedly stretch in outside the through hole 411 of valve seat 41.

As shown in Figure 5; when pushing the spool 42 that convexedly stretches in outside the valve seat 41; spool 42 relative valve seats 41 move down; then check valve 4 is to be in open mode; spring 43 is to be in compressive state simultaneously; if this moment, the highdensity cavernous body 21 of air bag 2 was to be in compressive state; gas just can entering in the air bag 2 under horizontal reset expands at cavernous body 21; treat in the air bag 2 behind the gassy; pine oil spool 42 is under the reset response of spring 43; recover normal condition, the shoulder shield 1 of this moment is to play the effect of using protection.When if protecting band band 1 desire will reduce volume, the same, when pushing the spool 42 that convexedly stretches in outside the valve seat 41, spool 42 relative valve seats 41 move down, and then check valve 4 is to be in open mode, simultaneously, the cavernous body 21 of extruding gasbag 2, after gas discharged from air bag 2, pine oil spool 42, check valve 4 recovers normal conditions.

As shown in Figure 6, when shoulder shield 1 was used for list shoulder knapsack, shoulder shield 1 was movable being placed on the backpack strip A, during use, only needs to pass through valve 3 air bag 2 gassies are got final product; And place the not time spent at knapsack, and only needing the gas in the air bag 2 to be emitted by valve 3, shoulder shield 1 just can not take too much space.

As shown in Figure 7, backpack is provided with shoulder shield 1 on this two backpack strip B, simultaneously in use, only needs by valve 3 air bag 2 gassies to be got final product; And place the not time spent at knapsack, and only need the gas in the air bag 2 to be emitted by valve 3, because its backpack strip B is provided with than big broad mostly, adopt structure of the present utility model, not only defencive function is good in the use, during collection, more can highlight its space-saving effect.

Claims
