In the stroller laboratory of Ningbo Cixi Entry-Exit Inspection and Quarantine Bureau’s Integrated Technical Service Center, it is not uncommon to see several models of children's bicycles with different brakes of the same model. The distinctive features of this brake are: Adjustable".
The so-called "adjustable brake lever" has a brake lever that adjusts the brake width by adjusting the tightness of the screw at the end of the brake lever. There is only one reason for companies to choose such a so-called “universal brake lever†because this type of “adjustable brake lever†can basically meet the requirements of the standard for the brake lever size. However, according to the laboratory's inspection of multiple models, it can be confirmed: The optional brake levers should be matched with the models, not suitable for the whole system, mainly due to the following two points:
One, if the same type of adjustable brake handle is installed on two different types of baby carriages (such as 12-inch baby stroller and 20-inch baby stroller), there will be a contradiction. If a small model is installed on a 20-inch vehicle, In the case of the adjustable brake lever, there will be a phenomenon of “bigfoot wear shoesâ€, which seems to be incongruous, and the “face value†of the vehicle is greatly reduced.
Second, if a large-sized adjustable brake lever is mounted on a 12-inch baby carriage, the brake operation will be inconvenient, and the brake stroke will be greatly reduced, so that the braking performance will also be greatly reduced. Laboratory history-related test data show that: After a large-scale adjustable brake lever is used to adjust the width and brake stroke of the brake, the brake force will be more than 30% less than before the adjustment, resulting in a greatly increased rate of unqualified brake performance items. Users bring security risks.
The child bicycle standard ISO 8098-2014 stipulates the width dimension of the baby carriage brake lever: that is, the maximum size of the brake lever midpoint to the inside of the sleeve should not exceed 60mm, and the distance from the end of the brake lever to the inside of the sleeve 20mm away from the sleeve should not exceed 75mm. The stroller company should understand and master the standards on the size requirements of the brake handles, and must fully consider the applicability and matchability of the matching and verify the safety and conformity of other projects. Do not make an adjustable one. The brakes were randomly installed on different models and resolutely put an end to the idea of ​​“drilling flaw detectionâ€. At the same time, it is necessary to continuously strengthen the technical requirements for the safety inspection of baby carriages, and always establish a quality goal of authenticity and quality.
