According to data, the first baby stroller was born in England in 1733. At that time, it was just a stroller with a basket similar to a carriage. After the 20th century, baby strollers became popular, and their basic materials, platform structure, safety performance and other aspects are also constantly improving. Nowadays, baby strollers have basically become a must-have for families, and the inspection of baby strollers is particularly important.
Different countries have different inspection standards and methods for products such as baby strollers. The following are common inspection requirements for baby strollers.
Baby stroller inspection requirements
1. Color matching check
2. Product specification inspection
3. Appearance inspection (plastic appearance, hardware appearance, pipe fitting appearance)
4. Finished product structure testing requirements
5. Requirements for component and rivet combinations
6. Requirements for lathe function inspection
7. Parasol inspection requirements
8. Packaging inspection requirements
The color matching is correct and meets the requirements of the order information. There is no wrong color or style.
2. Product specification inspection
1). Product specifications must be consistent with engineering and technical data;

3. Appearance inspection (plastic appearance, hardware appearance, pipe fitting appearance)
1). No orange peel, yellowing, delamination, blistering or burning;
2). No thick or thin wall phenomenon;
3). No dents or distortions;
4). Cut off the mold closing line and make it smooth;
5). The surface is bright and the color is uniform without impurities and color difference;

7). No forming edges and sharp points;
8). No dents, distortions, deformations, etc.;
9). No desoldering, missing soldering, bubbles, uneven welding, etc.
4. Finished product structure testing requirements
1). The brakes and removable parts operate normally and there is no failure;
2). The width of the platform is consistent with the design width: ±1.0mm;
3). Walking in a straight line: Sliding 5 meters from a 10-degree slope, with no deviation of 0.3 meters from left to right (reference standard JIS0294);

6). Push up and down test on the stroller handle (reference standard GB 14748)
Handlebar strength test method: Place the corresponding number of test weights in the sleeping bag and secure it with a safety belt. In a controlled manner, alternately raise or lower the handlebars so that the front and rear wheels are lifted by 120mm±10mm in turn. (As shown in the figure), and tested 800 times at a frequency of 15 cycles/min±2 cycles/min. For reversible handlebars, the test shall be conducted 400 times in each direction. If the handlebar has an adjustable device, the test shall be carried out under the most adverse conditions.
7). Cart impact strength test (reference standard GB 14748)
Impact strength test method: Place the corresponding number of test weights in the sleeping bag, secure it with a seat belt, place the vehicle on a 10° ramp, release the vehicle 1000mm away from the stop and let it drive down the ramp freely, and impact to a rigid stop whose height should be at least half the diameter of the wheel. Repeat the test a total of 10 times.

6. Requirements for lathe function inspection
1). The front and rear wheels must rotate flexibly. If the front wheels can be oriented, they must be firmly engaged;
2). All lathes with two locks must be locked firmly and cannot be detached;
3). If there is a reversing handle, the reversing spirit must be locked in place and firmly;
4). The contact surface between the wheel and the brake teeth is at least 5mm, and they must be firmly engaged and not disengaged;
5). The backrest adjustment should withstand a force of 15 kilograms without automatically sliding down, and the backrest adjustment should be smooth and not sluggish;
6). The pedal adjustment must be smooth;
