An impact table 11 is provided on the right side of the impact testing machine 10. A fixing mechanism 20 is provided on the top of the impact table 11. The fixing mechanism 20 includes a support platform 201 fixedly connected to the top of the impact table 11. The top of the support platform 201 is placed on the airbag body 40.

[0021] refer to Figure 2 , 3 The support platform 201 is fixedly connected to the front, back, left and right sides of the support rod 202. The outer side of the support rod 202 is hinged to a flip-up rod 203. The top of the flip-up rod 203 is connected to a fitting clamp 204 through a connecting mechanism 30.

[0022] Specifically, the support table 201 is sequentially provided with a first through slot 205 and a second through slot 208 from top to bottom, the first through slot 205 horizontally penetrates the support table 201, and the second through slot 208 longitudinally penetrates the support table 201; the first through slot 205 is fixedly connected with a first double-acting cylinder 206, the left and right output ends of the first double-acting cylinder 206 are hingedly connected with a first connecting rod 207 through a hinge, and the other side of the first connecting rod 207 is hingedly connected with a turnover rod 203 through a hinge; the second through slot 208 is fixedly connected with a second double-acting cylinder 209, the front and rear output ends of the second double-acting cylinder 209 are hingedly connected with a second connecting rod 210 through a hinge, and the outer side of the second connecting rod 210 is hingedly connected with a corresponding turnover rod 203 through a hinge.

[0023] Before use, the airbag body 40 to be detected is placed on the top of the support table 201, and then the first double-acting cylinder 206 and the second double-acting cylinder 209 are started at the same time, the left and right output ends of the first double-acting cylinder 206 drive the turnover rod 203 to turn inward through the first connecting rod 207 until the left and right sides of the airbag body 40 are clamped and fixed by the clamping blocks 204, the front and rear output ends of the second double-acting cylinder 209 drive the corresponding turnover rod 203 to turn inward through the second connecting rod 210 until the front and rear sides of the airbag body 40 are clamped and fixed by the corresponding clamping blocks 204, and the four sides of the clamping blocks 204 clamp the top boundary of the airbag body 40 without covering too much of the surface of the airbag body 40, so as not to affect the impact test of the impact testing machine 10 on the airbag body 40.

[0024] In use, the airbag body 40 is detected by the impact testing machine 10, and different positions of the airbag body 40 are impacted by impact hammers of different forces to obtain test data; when the left and right sides of the airbag need to be impacted for testing, the output end of the first double-acting cylinder 206 needs to be retracted in advance, the left and right clamping blocks 204 are driven to turn outward by the first connecting rod 207, the airbag body 40 is fixed by the front and rear clamping blocks 204, and then the airbag body 40 is impacted for testing. Similarly, when the front and rear sides of the airbag body 40 are impacted for testing, the output end of the second double-acting cylinder 209 also needs to be retracted in advance.

[0025] Preferably, the inner side surface of the clamping block 204 is matched with the shape of the outer side surface of the airbag body 40, so that when the clamping block 204 clamps the surface of the airbag body 40, it can be in contact with the surface of the airbag body 40 in a large area, thereby enhancing the clamping and fixing effect of the airbag body 40.

[0026] Since different types of airbags have different shapes, a single fitting clamp 204 cannot meet the clamping and fixing effect of different shaped airbags. In order to replace the fitting clamp 204 that is suitable for different shaped airbags conveniently, a connecting mechanism 30 is provided.

[0027] Reference Figure 4 The connecting mechanism 30 comprises a connecting frame 301 fixedly connected to the bottom of the fitting clamp 204, and a positioning groove 302 is formed in the left and right sides of the inside of the connecting frame 301; the connecting mechanism 30 further comprises a sliding groove 303 formed in the top of the left and right sides of the turnover rod 203, a supporting spring 309 is fixedly connected to the inside of the sliding groove 303, and a movable positioning block 304 is fixedly connected to the outside of the supporting spring 309.

[0029] Preferably, the outside end of the positioning block 304 is in an arc shape that gradually lengthens from top to bottom; when replacing, the corresponding moving frame 308 is first slid downward, the moving frame 308 drives the connecting rod 307 and the Y-shaped rope 306 to move downward, thereby driving the two sides of the positioning block 304 to move inward and disengage from the positioning groove 302, then the fitting clamp 204 is pulled out upward, and then the connecting frame 301 of the new fitting clamp 204 is inserted into the top of the turnover rod 203, when the surface of the connecting frame 301 contacts the surface of the positioning block 304, the contact force causes the two positioning blocks 304 to slide inward and drive the supporting spring 309 to compress, until the positioning groove 302 corresponds to the position of the positioning block 304, and then the supporting spring 309 rebounds to drive the positioning block 304 to move outward and insert into the inside of the positioning groove 302, thereby completing the installation of the new fitting clamp 204.

[0030] The working principle of the utility model is: the safety air bag body 40 to be detected is placed on the top of the support table 201, then the first double -way air cylinder 206 and the second double -way air cylinder 209 are started simultaneously, the left and right sides output end of the first double -way air cylinder 206 is driven to the inside overturning of the turnover rod 203 through the first connecting rod 207, until the left and right sides of the safety air bag body 40 are clamped and fixed by the fitting clamp block 204, the front and rear sides output end of the second double -way air cylinder 209 is driven to the inside overturning of the corresponding turnover rod 203 through the second connecting rod 210, until the front and rear sides of the safety air bag body 40 are clamped and fixed by the corresponding fitting clamp block 204, and the top boundary of the safety air bag body 40 is clamped by the four sides fitting clamp block 204, too much surface of the safety air bag body 40 is not covered, so that the impact testing machine 10 will not affect the impact detection of the safety air bag body 40. The basic principle, main features and advantages of the utility model are shown and described above. The skilled in the art should understand that the utility model is not limited by the above examples, the above examples and the description in the specification are only to illustrate the principle of the utility model, under the premise of not departing from the spirit and scope of the utility model, the utility model will also have various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model.
