[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This utility model provides a painting fixture for automotive airbag covers, such as... Figures 1 to 6 As shown.

[0035] Example 1:

[0036] A painting fixture for automotive airbag covers includes a main shaft 1, a flange 2 coaxially mounted on the side of the main shaft 1, the flange 2 being fixedly connected to the rotary drive mechanism of a painting equipment by bolts, and multiple branch rods 3 being movably engaged on the main shaft 1, the multiple branch rods 3 being evenly distributed along the circumference of the main shaft 1.

[0037] A snap-fit ​​block 4 is fixedly connected to one end of the branch rod 3 near the axis of the main shaft 1. The snap-fit ​​block 4 is T-shaped. The main shaft 1 is provided with a slot 5 that matches the snap-fit ​​block 4. The snap-fit ​​block 4 and the slot 5 engage with each other.

[0038] Two abutment parts 6 are fixedly installed on the side wall of the slot 5 away from the axis of the main shaft 1. The two abutment parts 6 are located on both sides of the vertical end side wall of the snap-fit ​​block 4, and are used to abut the horizontal end side wall of the snap-fit ​​block 4. The abutment parts 6 are made of elastic material (such as spring steel sheet) and are arched in shape. The top of the arch abuts the horizontal end side wall of the snap-fit ​​block 4. The snap-fit ​​block 4 is provided with a groove 7 that matches the abutment parts 6. When the snap-fit ​​block 4 is inserted into the slot 5, the abutment parts 6 will be embedded in the groove 7, so that the snap-fit ​​block 4 can be stably inserted into the slot 5.

[0039] A support is fixedly connected to the end of the branch rod 3 that is away from the axis of the main shaft 1. The support is used to support and fix the airbag cover.

[0040] Example 2:

[0041] The support includes a base plate 8, which is fixedly connected to one end face of the branch rod 3 away from the axis of the main shaft 1. A snap-fit ​​component is fixedly connected to the base plate 8. The snap-fit ​​component is made of an elastic material (such as spring steel) and is interference-fitted with the airbag cover to fix the airbag cover in a snap-fit ​​manner.

[0042] The locking mechanism includes two spring rods 9, which are fixedly connected to both sides of the base plate 8. The two ends of the spring rods 9 are folded towards each other to form locking angles. The spring rods 9 are press-fitted with the airbag cover through the locking angles formed at their two ends. The two spring rods 9 form a total of four locking angles, thereby stably supporting and fixing the airbag cover.

[0043] Example 3:

[0044] Based on Embodiment 2, in order to facilitate the disassembly and assembly of the airbag cover by the staff, a sliding frame 10 is provided on both sides of the branch rod 3. The sliding frame 10 is U-shaped, and its open end is inserted into the sliding groove 11 provided on the branch rod 3. The folding end of the spring rod 9 abuts against the side wall of the sliding frame 10. The closed end of the sliding frame 10 is threadedly connected to the bidirectional bolt 12 rotatably installed on the branch rod 3. The threads at both ends of the bidirectional bolt 12 are symmetrical to each other. By rotating the bidirectional bolt 12, the two sliding frames 10 located on the same branch rod 3 can move towards each other or away from each other.

[0045] When the two sliding frames 10 move toward each other, the side wall of the sliding frame 10 can be separated from the folding end of the spring rod 9. At this time, the sliding frame 10 no longer applies a supporting force to the folding end of the spring rod 9. At this time, the distance between the folding angles at both ends of the spring rod 9 will be reduced, and the pressing force of the spring rod 9 on the airbag cover will be reduced accordingly, which makes it easier for the staff to disassemble and install the airbag cover.

[0046] When the two sliding frames 10 move in opposite directions, the side wall of the sliding frame 10 can abut against the folding end of the spring rod 9, so that the folding angles at both ends of the spring rod 9 can stably support the airbag cover.

[0047] Furthermore, in order to enable the slide frame 10 to move more smoothly between the two folding ends of the spring rod 9, the closed end of the slide frame 10 is set to be arc-shaped.

[0048] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
