[0005] The impact block 5 is fixed on the rubber conveyor belt 4 by riveting. The disadvantage of this structure is that the bottom surface of the impact block 5 is a plane with a width of 140 mm. When the rubber conveyor belt 4 at the impact block 5 passes through the rotating drum 3 , the arc of the rotating drum 3 does not coincide with the plane of the bottom surface of the impact block 5, and the impact block 5 is tilted on the rubber conveyor belt 4, so that the riveting of the rubber conveyor belt 4 and the fixed impact block 5 is easily damaged. 4. The service life is low, and the rubber conveyor belt is constantly replaced. 4. Waste of manpower and material resources

Embodiment Construction
[0021] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail: Figure 4 It is an improved structure diagram of the impact block structure of the children's stroller durability test machine. Figure 5 yes Figure 4 The A-A section diagram.
[0022] Depend on Figure 4 , 5 It can be seen in the figure that the impact block structure of the children's stroller durability testing machine is composed of a rubber conveyor belt 4, a clip 7, a hook 8, a hook nut 9, a screw shaft 10, and an A impact block 11;
[0023] Grab hook 8 is U-shaped, hooked on the rubber conveyor belt 4 from inside to outside, and clip strip 7 is in the shape of a narrow strip. The hook nut 9 at the U-shaped end of the hook 8 fixes the clamp strip 7 on the rubber conveyor belt 4 . Because the clip 7 is in the shape of a narrow strip, and the contact width with the rubber conveyor belt 4 is small, the U-shaped grab 8 is also installed in...

The invention provides an impact block structure for children trolley durability-testing machines, which consists of a rubber conveyor belt, a clamping strip, a clamping hook, a clamping hook nut, screw shafts and an impact block A, wherein the clamping hook is in a U shape and is hooked on the rubber conveyor belt; the clamping strip is in the shape of a narrow long strip; the clamping hook nut positioned at the end of the U shape of the clamping hook fixedly installs the clamping strip on the rubber conveyor belt; two ends of the clamping strip are provided with screw holes; two screw shaftsare arranged in the screw holes at two ends of the clamping strip; the lower part of the impact block A is provided with a long strip hole holding the clamping strip; two ends of the impact block A are provided with round holes; and the necks of the two screw shafts support the round holes at two ends of the impact block A in order to enable the impact block A to swing on the clamping strip. Theimpact block structure has the advantages of ensuring that the rubber conveyor belt and the connection fixing the impact block A are not easy to damage, ensuring the long lifespan of the rubber conveyor belt and reducing the waste of manpower and material resources.
Description
technical field [0001] The invention relates to the field of strollers for children. Background technique [0002] Strollers are vehicles for infants and young children to be promoted by adults, which are conducive to the growth and development of children and are very popular among people. Children's strollers must have good quality and safety performance. In order to ensure the quality and safe and effective use of children's strollers, the country has promulgated the national standard GB14748-2006 safety requirements for children's strollers. The standard stipulates that various children's strollers Vehicle performance and testing methods. [0003] In GB14748-2006 Safety Requirements 5.18 for strollers, manufacturers of strollers are required to conduct dynamic durability tests. figure 1 Schematic diagram of the dynamic durability test for the children's stroller dynamic durability test machine, the children's stroller dynamic durability test machine includes the child'...
