[0027] This utility model provides a three-sided folding airbag jack.

[0028] like Figure 1-5As shown, the three-sided folding airbag jack provided in this embodiment of the utility model includes a base component 10, an airbag component 20, and a handle component 30. The base component 10 includes a bottom plate 12, a top plate 11, and a retractable structure 13 connecting the bottom plate 12 and the top plate 11. The base component 10 has a receiving cavity 14 for accommodating the airbag component 20. The bottom plate 12 and the top plate 11 are triangular, and a top block 50 is provided on the top plate 11.

[0029] In this embodiment, when the airbag component 20 is inflated and lifted, it can be lifted by the top plate 11 on the outside of the airbag component 20. Compared with the airbag lifting directly, it has a larger contact area and improves the stability during lifting. Thus, after the top block 50 and the top plate 11 are at the bottom of the car chassis and one side of the car is lifted, the staff can repair the car chassis or tires.

[0030] Please refer to the following: Figure 4-5 The retractable structure 13 includes two lower connecting rods 131 connected to the base plate 12, an upper connecting rod 132 connected to the top plate 11, and a rotating shaft 133. The ends of the lower connecting rods 131 and the upper connecting rod 132 are hinged to the rotating shaft 133, and the upper connecting rod 132 is located between the two lower connecting rods 131. In this embodiment, the upper connecting rod 132 and the lower connecting rod 131 are connected to the top plate 11 and the base plate 12 respectively via a hinge shaft 135. Therefore, when the airbag component 20 is lifted, the height of the receiving cavity 14 can be expanded by rotation through the action of the rotating shaft 133 and the hinge shaft 135 to accommodate the airbag component 20. At the same time, steel wire ropes or chains can be added between the airbag component 20 and the base component 10 for reinforcement, greatly improving the stability of the product.

[0031] The base plate 12 and top plate 11 of this application are formed by folding an equilateral triangle at a certain angle. A hinge seat is welded at the triangle. The lower connecting rod 131 and the upper connecting rod 132 are connected to the hinge seat by screws to form a hinge shaft 135.

[0032] In another embodiment, the contraction structure 13 can also be adjusted using a multi-link structure, which will not be described in detail here.

[0033] In addition, the retractable structure 13 also includes transfer wheels 134 installed at both ends of the rotating shaft 133. Therefore, the user can push the product through the handle structure, and the product can move under the action of the transfer wheels 134, improving the product's movement efficiency. At the same time, the adjusting plate 40 connecting the extension rod 31 and the base component 10 can be used to make the retaining rod on the extension rod 31 engage in different slots 41, so that the extension rod 31 and the base component 10 can have different tilt angles, which is convenient for the user to operate.

[0034] Please refer to Figure 2-3 The handle component 30 includes an extension rod 31, a grip handle 32, and a control component 33 mounted on the grip handle 32. One end of the extension rod 31 is connected to the base plate 12, and the control component 33 is located at the other end of the extension rod 31. The control component 33 is connected to the airbag component 20 via an air tube 34. The control component 33 includes an air inlet valve 331, a pressure relief valve 332, and an air outlet valve 333, all of which are connected to the air tube 34. The air inlet valve 331 is provided with a quick-connect connector 334, and the air outlet valve 333 is provided with a silencer 335.

[0035] The air source is connected to the quick-connect fitting 334, and the air inlet valve 331 is opened. Compressed air enters the airbag component 20 through the air pipe 34, causing the airbag component 20 to inflate and rise rapidly. The top block 50, located at the bottom of the car chassis, quickly lifts one side of the car, allowing workers to repair the chassis or tires. After the car repairs are completed, the air inlet valve 331 is closed, and the exhaust valve is opened, allowing the air in the airbag component 20 to be quickly released, causing the airbag component 20 to descend. When the air pressure exceeds a set value, the pressure relief valve 332 automatically opens to release pressure. When the pressure returns to a certain value, the pressure relief valve 332 closes, preventing excessive air pressure from damaging or even causing the airbag to explode.

[0036] This application adopts a three-sided folding design, with each part featuring a sheet metal and welded structure, facilitating processing and reducing manufacturing costs. The connecting rods utilize a strip-shaped structure, offering better bending and tensile strength, and a longer service life. It enables rapid lifting during vehicle chassis repairs or tire changes, and is easy to operate.

[0037] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
