An upper cap 7 is provided at the upper airbag inlet, and a lower cap 8 is provided at the lower airbag inlet. Both the upper cap 7 and the lower cap 8 have three spaced-apart annular grooves on their outer sides. Correspondingly, three annular protrusions are located on the inner side of the rubber layer 5. When the rubber layer 5 is fitted onto the upper cap 7 or the lower cap 8, the protrusions of the rubber layer 5 are embedded in the grooves on the outer sides of the caps.

In this embodiment, a clamping fixture is placed on the outer side of the metal buckle 6, and the conical movable block 3 of the clamping fixture presses against the metal buckle 6, causing the metal buckle 6 to deform and further tighten the rubber layer 5, thereby further improving the sealing performance of the airbag inlet.

[0026] The clamping fixture includes an upper positioning sleeve 1, a lower positioning sleeve 4, a conical outer sleeve 2, and a conical movable block 3. A recessed positioning groove 41 is provided on the top of the lower positioning sleeve 4, and the conical movable block 3 is positioned within the positioning groove 41. An outer inclined surface 31 is provided on the outer side of the conical movable block 3, and the outer outer sleeve 2 is also provided around the outer inclined surface 31. An inner inclined surface 21, matching the outer inclined surface 31 of the conical movable block 3, is provided on the inner side of the outer outer sleeve 2, so that the conical movable block 3 and the outer outer sleeve 2 contact each other in a beveled engagement manner.

[0027] The upper positioning sleeve 1 is arranged above the conical sleeve 2. When the upper positioning sleeve 1 is pressed downward, the conical sleeve 2 is driven to move downward. The inner inclined surface 21 of the conical sleeve 2 can extrude the outer inclined surface 31 of the conical movable block 3, so that the conical movable blocks 3 in the positioning groove 41 can move together along the radial direction to the air bag sub-port, and all the conical movable blocks 3 can extrude the metal clasp 6 to generate deformation, the metal clasp 6 can extrude the air bag sub-port rubber layer 5, so that the rubber layer 5 can tightly hold the air bag upper sub-port or the air bag lower sub-port in the radial direction, and the air bag sub-port is sealed.

[0028] As shown in Figure 1 , Figure 3 and Figure 4 , the conical sleeve 2 is a hollow circular ring, the hole diameter of the upper end of the inner inclined surface 21 of the conical sleeve 2 is smaller than the hole diameter of the lower end of the inner inclined surface 21. The outer side of the top of the conical sleeve 2 is provided with an annular step, the bottom of the annular step is an upper end surface 22, the inner side of the annular step is an upper vertical surface 23, and the upper vertical surface 23 is perpendicular to the upper end surface 22. The upper positioning sleeve 1 is a circular tube, the lower end of the upper positioning sleeve 1 is in abutment with the upper end surface 22 of the annular step at the top of the conical sleeve 2, and the inner side wall of the upper positioning sleeve 1 is tightly sleeved on the upper vertical surface 23 at the top of the conical sleeve 2.

[0029] As shown in Figure 1 , Figure 5 and Figure 6 , a spacing is arranged between each conical movable block 3, and an arc-shaped step is arranged on the outer side of the bottom of the conical movable block 3. The side surface of the inner side of the arc-shaped step is a lower vertical surface 33, the top plane of the arc-shaped step is a lower end surface 32, and the lower vertical surface 33 is perpendicular to the lower end surface 32. The inner side of the conical movable block 3 is formed with an extrusion surface 34, the lower end of the extrusion surface 34 of the conical movable block 3 is provided with an arc-shaped protruding block 35 protruding inward, and the metal clasp 6 is placed at the arc-shaped protruding block 35. The self-gravity of the upper positioning sleeve 1 and the conical sleeve 2 acts on the inclined surface of the conical movable block 3, so that the conical movable blocks 3 in the positioning groove 41 move to the air bag sub-port, so that the extrusion surface 34 of each conical movable block 3 tightly abuts the outer side surface of the metal clasp 6, and the bottom of the metal clasp 6 is in abutment with the arc-shaped protruding block 35 of the conical movable block 3.

[0030] The lower end surface 32 of the arc-shaped step at the bottom of the conical movable block 3 is embedded in the positioning groove 41 at the top of the lower positioning sleeve 4, and the conical movable block 3 can slide in the positioning groove 41. The lower vertical surface 33 of the arc-shaped step at the bottom of the conical movable block 3 can be in abutment with the inner side of the lower positioning sleeve 4, so as to play a radial positioning role. Thus, after the clamping tool is installed, the inner side of the conical movable block 3 can be in abutment with the outer side of the metal clasp 6 to form a certain pre-pressing force, so as to prevent the air bag from falling.

Then the lower conical movable block 3 is respectively clamped into the corresponding positioning groove 41, and is in contact with the metal snap ring 6. Then the conical outer sleeve 2 is sleeved, and finally the upper positioning sleeve 1 is placed, and the equipment is used to apply vertical downward pressure to the upper positioning sleeve 1, so that the conical outer sleeve 2 can extrude the outer inclined surface 31 of the conical movable block 3 through the inner inclined surface 21 when moving downward, so that the conical movable blocks 3 in the positioning grooves 41 can move together along the radial direction to the air bag sub-port, and the conical movable blocks 3 extrude the metal snap ring 6 to produce deformation, so that the metal snap ring 6 extrudes the rubber layer 5 at the air bag sub-port, and the rubber layer 5 radially tightly holds the air bag sub-port to realize sealing. After the air bag sub-port at one end is sealed, the other end of the air bag sub-port is sealed by the same method.
