[0019] Example 1: Please refer to Figure 1-4 In this embodiment, an air spring with a sunken air nozzle includes a second circular plate 3 and a curved plate 4. The rear end surface of the second circular plate 3 is connected with a mounting structure 2. The mounting structure 2 includes a first circular plate 201 and a first bolt 202. The front surface of the first circular plate 201 fits with the rear end surface of the second circular plate 3. The upper part of the front surface of the first circular plate 201 is threadedly connected with the outer wall of the first bolt 202. A straight cylinder 203 is slidably connected with the front notch of the first circular plate 201. The straight cylinder 203 is subjected to force to slide in the front notch of the first circular plate 201. The inner wall of the straight cylinder 203 is threadedly connected with the second bolt 204.

[0020] The position of the straight cylinder 203 is adjusted by sliding the straight cylinder 203 in the installation structure 2 in the groove on the front side of the first circular plate 201, and then the second circular plate 303 is fitted with the front side of the first circular plate 201, and then the first bolt 203 passes through the second circular plate 3 and is threadedly connected to the upper front side of the first circular plate 201, and then the second bolt 203 passes through the second circular plate 3 and is threadedly connected to the inner wall of the straight cylinder 203, completing the installation of the curved plate 4, ensuring the normal installation of the air spring and eliminating the limitations of the use of the air spring.

[0021] The outer walls of the first bolt 202 and the second bolt 204 are both threadedly connected to the outer wall of the second circular plate 3, and the first bolt 202 and the second bolt 204 fix the second circular plate 3 and the first circular plate 201. The front side of the second circular plate 3 is fixedly connected to the rear end face of the curved plate 4, and the rear end face of the first circular plate 201 is fixedly connected to the air spring 1. How to operate and use the air spring 1 is already the prior art, and no further elaboration will be given. The model is selected according to usage requirements. The top front of the air spring 1 is connected to an air nozzle 5, and the model of the air nozzle 5 is used according to usage requirements. The top of the inner wall of the air nozzle 5 is threadedly connected to a plug 6, and the plug 6 is made of rubber.

[0022] Working principle:

[0023] Air Spring Installation:

[0024] Place the air spring 1 vertically, and then according to the position of the circular mouth of the outer wall of the second circular plate 3, slide the straight cylinder 203 in the groove on the front side of the first circular plate 201 to adjust the position of the straight cylinder 203, and then fit the second circular plate 303 with the front side of the first circular plate 201, and then the first bolt 203 passes through the second circular plate 3 and is threadedly connected with the upper front side of the first circular plate 201, and then the second bolt 203 passes through the second circular plate 3 and is threadedly connected with the inner wall of the straight cylinder 203 to complete the installation of the curved plate 4, and then the inner wall of the curved plate 4 is connected through the external vehicle body rod.

[0025] Air spring use:

[0026] The plug 6 is screwed through the notch on the top with a screwdriver to gradually separate the plug 6 from the top of the air nozzle 5. Then, air is inflated into the air spring 1 through the air nozzle 5 to adjust the height of the air spring 1. Then, the plug 6 is screwed into the top of the air nozzle 5. The air nozzle 5 is set on the outer wall of the air spring 1 in a sunken type to avoid deformation and damage caused by the leakage of the air nozzle. The air spring 1 consists of a closed container and an elastomer filled with gas. When external pressure is applied or an object is loaded, the air spring will produce elastic deformation to provide corresponding elastic force.

[0027] Example 2: Please refer to Figure 1-4: In this embodiment, an air spring with a sunken air nozzle also includes round rods 7 and straight rods 8. The rear end faces of the multiple round rods 7 are fixedly connected to the rear of the circular groove on the outer wall of the air spring 1, the inner walls of the multiple round rods 7 are respectively fitted with the outer walls of the straight rods 8, and the front faces of the multiple straight rods 8 are all fixedly connected to the front of the circular groove of the air spring 1.

[0028] Working principle:

[0029] When the air spring 1 is squeezed, the whole will be compressed toward the center position, and the straight rod 8 will move toward the inner wall of the round rod 7. The straight rod 8 and the round rod 7 can prevent the center position of the air spring 1 from expanding outward.
