The specific embodiment
Squash type airbag apparatus described in the utility model can be applicable to the product that safety cap or the similar liner that needs the buffering that expands protect etc., and present embodiment is to be that example is described in detail with the safety cap.
As shown in Figure 1 and Figure 2, squash type airbag apparatus described in the utility model, comprise extruding air pump 1 and the air bag 40 that is connected with extruding air pump 1, described extruding air pump 1 comprises pedestal 10 and the flexible sheet 20 that places on the pedestal 10, and described pedestal 10 is with flexible sheet 20 corresponding pressings and form the extruding air pump 1 with sealed gas chamber.Described air bag 40 is provided with the passage 41 that is connected with the steam vent 13 of the pedestal 10 that pushes air pump 1, and the gas bleeder valve 42 that the gas in the air bag 40 can be released.
As Fig. 3～shown in Figure 5, described pedestal 10 is made of plastics, the periphery of these pedestal 10 end faces is provided with a circle bulge loop 11, the inboard of this bulge loop 11 is provided with an outstanding base 12, described steam vent 13 places the bottom position of base 12 inside, the periphery of pedestal 10 is provided with first a smooth sealing the margin 14, is embedded with air bleeding valve 30 in the base 12 of pedestal 10.These flexible sheet 20 curved designs, adaptive with the nose shape of human body, be lining in the safety cap in can be preferably.The one-body molded valve seat that is arranged with 21 that is provided with on the described flexible sheet 20, valve seat 21 bottoms are provided with air admission hole 22, be embedded with intake valve 30a on the valve seat 21, described flexible sheet 20 peripheries are provided with second sealing the margin 23, first sealing the margin, the 14 corresponding pressings of this second sealing the margin 23 and pedestal 10, with pedestal 10 and the flexible sheet 20 corresponding extruding air pumps 1 with ccontaining gas cavity that are combined into, this extruding air pump 1 forms an integral gasbag 2 in conjunction with air bag 40.
As Fig. 6, shown in Figure 7, in the utility model, the air bleeding valve 30 on the pedestal 10 is the identical in structure Non-return air valve with the intake valve 30a on the flexible sheet 20, and air bleeding valve 30 is provided with intake valve 30a is contiguous.Described air valve comprises valve gap 31 and the valve block 32 that places valve gap 31 inside, and wherein valve gap 31 center of top places are provided with a through hole 311, and the internal face of valve gap 31 is provided with three fins 312, and the outer ledge place of the opening part of valve gap 31 is provided with a flange 313.The bottom of described valve block 32 is provided with four soft cylinders 321, be provided with groove 322 between the adjacent soft cylinder 321, in addition, the end face of valve block 32 is provided with airtight edge 323, like this, just makes that valve block 32 can movable being arranged in the valve gap 31, contact is contacted with the basal surface position of valve gap 31 through holes 311 under the described valve block 32 end face normalities, in addition because the outer ledge place of the opening part of valve gap 31 is provided with a flange 313, so just make valve gap 31 correspondences be embedded in base 12 and valve seat 21 also can closely cooperate.
Below be described in detail with regard to the operation principle of squash type airbag apparatus described in the utility model:
When applying external force when pushing the flexible sheet 20 of air pump 1, valve block 31 in the air bleeding valve 30 on the pedestal 10 will be subjected to discharging the extruding of gas pressure, the airtight edge 323 of valve block 32 breaks away from the through hole 311 of valve gap 31, the effect that makes the soft cylinder 321 of valve block 31 bottoms be under pressure produces flexural deformation, like this, air in the air chamber of extruding air pump 1 cavity can be entered by the through hole 311 at air bleeding valve 30 valve gaps 31 tops, and the groove 322 through valve block 32 bottoms is communicated with steam vent 13 discharges.When stopping to apply external force in extruding air pump 1, flexible sheet 20 produces elastic-restoring force, the airtight edge 323 of the valve block 32 of intake valve 30a is subjected to suction function to break away from the through hole 311 of valve gap 31 at this moment, air outside then can be entered by the through hole 311 at intake valve 30a valve gap 31 tops of flexible sheet 20, and the groove 322 through valve block 32 bottoms is communicated with air admission holes 22 and enters in extruding air pump 1 air chamber, when flexible sheet 20 returns back to swelling state fully (shown in Fig. 4,5).More than can finish by the process of pushing described extruding air pump 1 and realize pushing inflation and exhaust process in the air pump 1, in addition, because air bleeding valve 30 is provided with intake valve 30a is contiguous, and reverse each other check valve, this kind structure not only reserve the more application of force of extruding air pump space, and extruding air pump 1, intake valve 31a is closed when exhaust condition, otherwise air bleeding valve 31 is closed when the air inlet state, when making continuously extruded this extruding air pump 1, can reach the purpose of exhaust in time after the air inlet.
As shown in Figure 1 and Figure 2, extruding air pump 1 combines with air bag 40, air bag 40 is provided with the passage 41 with the steam vent 13 corresponding connections of pushing air pump 1, like this, after the bottom sealing of first sealing the margin 14 of air bag 40 and extruding air pump 1 combine, this air bag 40 just with push air pump 1 formation one integral gasbag 2.In addition, owing to also be provided with gas bleeder valve 42 on the air bag 40, can freely lose heart by this gas bleeder valve 42 and regulate the size of aeration quantity in the air bag 40, thereby can the be real-time gas in the air bag 40 be discharged reaches disappointing purpose.During use, to be lining in the safety cap in the air bag 40, the user inflates 1 pair of air bag 40 of extruding air pump, when air bag 40 is inflated to swelling state by this extruding air pump 1 of continuous extruding, the air bag 40 that expands has cushioning effect preferably, when the external influence masterpiece was used for safety cap, because the cushioning effect of air bag 40, it can absorb bigger impact and decompose, make that the external force that directly affacts head is less, the better protect head; In addition, tolerance is adjustable in the air bag 40, and therefore, the size of air bag 40 can adapt to safety cap wearer's head size, makes the suitable coating wearer's of its energy head, comfortable wearing, and it is wide, practical to be suitable for the crowd.
Present embodiment is only illustrated with the interior squash type airbag apparatus that is lining in the safety cap; but it is not limited to safety cap; it can also be applicable to that any similar liner that needs the buffering that expands protects or use comfortable product; for example knee-pad, shoulder protector etc.; its principle is basic identical, and difference is that the profile of air bag 40 needs corresponding with protected position.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or modification are not broken away from spirit and scope of the present utility model, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then the utility model also comprises these changes and modification.
