Problems solved by technology

[0002] At present, the jacks equipped with small cars are almost all mechanical screw shaking or hydraulic lifting. Because of the small contact area of ​​these two types of jacks, the position required for the upper apex must be at the position specified by the automobile manufacturer. The apex is required to be accurate, and the bottom of the mechanical jack A floor with a relatively large area and a certain strength is required to prevent subsidence. The process of raising the roof is laborious, which is likely to cause damage to the bottom of the car, and has a single purpose

Abstract

The invention relates to the technical field of jacks for automobiles, in particular to an inflatable jack which comprises an air bag. An air nozzle assembly is arranged on the air bag and comprises an air nozzle, an air nozzle cover and an air guide structure, the air nozzle is fixedly arranged on the air bag, the air nozzle cover is used for covering the air nozzle, the air guide structure is used for being fixedly matched with the air nozzle cover, a through hole is formed in the middle of the air nozzle, the air guide structure penetrates the through hole, and the air nozzle can be opened or closed under the matching movement of the air guide structure and the air nozzle cover. The inflatable jack has the advantages that heavy objects can be hoisted in an air bag mode, the inflatable jack is large in contact area and is made of special raw materials, force can be diffused, accordingly, air can be easily pumped into the air bag in manual air filling procedures, the inflatable jack is particularly practical for automobiles in fields and can be tucked in load-bearing positions at the bottoms of the automobiles without requirements on hoisting points, plates for being cushioned at the bottom of the air bag can be omitted, the automobiles can be hoisted as long as the automobiles do not sink on large areas, and height requirements can be omitted.

Description

technical field [0001] The invention relates to the technical field of automobile jacks, and more specifically, relates to an inflatable jack. Background technique [0002] At present, the jacks equipped with small cars are almost all mechanical screw shaking or hydraulic lifting. Because of the small contact area of ​​these two types of jacks, the position required for the upper apex must be at the position specified by the automobile manufacturer. The apex is required to be accurate, and the bottom of the mechanical jack A floor with a relatively large area and a certain strength is required to prevent subsidence. The process of raising the roof is laborious, which is likely to cause damage to the bottom of the car, and has a single purpose. Contents of the invention [0003] The invention provides an inflatable jack which is convenient to inflate and deflate and is not easy to leak. [0004] In order to solve the problems of the technologies described above, the techni...
