This standard specifies the basic technical requirements and test methods for the safety, structural strength and performance of clockwork toys. This standard applies to all kinds of toys with clockwork as the power source. Referenced Standards
The provisions contained in the following standards constitute the provisions of this standard through reference in this standard. When this standard is published, the versions shown are valid. All standards are subject to revision, and parties using this standard should explore the possibility of using the latest version of the following standards.
GB6675-86 Toy Safety
3 Technical Requirements
3.1 Safety Requirements
3.1.1 The safety requirements for clockwork toys shall comply with the relevant provisions of GB6675. 3.1.2 If there is a hole on the clockwork key, its diameter@ shall be less than 4.8mm, see Figure 1. Figure 1
3.2 Performance Requirements
3.2.1 After the clockwork toy is fully wound, it can perform the prescribed actions continuously without external assistance. 3.2.2 The distance traveled by the product, the time of action or the number of turns of the clockwork key shall comply with the provisions of Table 1 after the test is carried out according to 4.2.
Traveling category
1 For toys with a total length of not less than 10cm, the distance they travel should be more than 3m
2 For toys with a total length of less than 10cm or that travel in water, the distance they travel should be more than 2m
Approved by China Light Industry Federation on March 27, 1998Other categories
After the toy is fully wound, the continuous action time should be more than 30s or the number of rotations of the winding key should be no less than 8 (one rotation of the winding key is 180°)

QB/T 2360-98
3.2.3 Products with straight-line driving function shall be tested in accordance with 4.3, and the deviation P shall not be greater than 0.25.3.3 Structural strength
3.3.1 After the sample is subjected to 300 life tests in accordance with 4.4, it shall be able to maintain its original function. Failure, loose parts, falling off and other undesirable phenomena shall not occur.
3.3.2 After the spring over-tightening test is carried out on the sample according to 4.5, there shall be no damage and the functional requirements shall be met. 3.3.3 After the emergency stop strength test is carried out three times according to 4.6, the product shall not have any damage and can still meet its functional requirements.
Test method
4.1 Test environment
4.1.1 For ground-running toys, the test shall be carried out on a flat, level floor or cement terrazzo floor. 4.1.2 For water-running toys, the test shall be carried out in a container that is large and deep enough. 4.1.3 For aerial hanging and other toys, the test shall be carried out in a laboratory. 4.2 Travel distance, action time or number of turns of the winding key After the sample is fully wound, make a preparatory action first. After the action of the sample stops, the full winding test can be carried out and the following records are made:
a) Use a stopwatch to measure the time of continuous action of the sample; b) Use a tape measure to measure the travel distance of the sample; o) Number of turns of the winding key.
During the test, the sample shall not continue to move after stopping in any way. After the test, check whether the sample meets the requirements of 3.2.2.
4.3 Straight-line driving test
After the sample is fully wound, make it drive straight on a flat and horizontal floor or cement terrazzo floor as shown in Figure 2. After the sample stops, measure the driving distance and calculate the deviation according to the following formula. P=s
Deviation:
Where: p-
S----The vertical distance from the midpoint of the line connecting the contact points of the two driving wheels (or two driving components) of the sample with the ground to the midline of the sample test, m.
L——The distance from the midpoint of the line connecting the contact points of the two active wheels (or two active driving parts) of the sample with the ground to the starting line of the sample test, m:
Note: The two active driving parts refer to other driving mechanisms other than the above-mentioned active wheels, such as the two feet of a robot. The above test should be repeated three times and the average value is taken.
Check whether it meets the requirements of 3.2.3.

4.4 Life test
QB/T2360—98
Test midline
Test starting line of the sample
4.4.1 After the sample is fully wound up, it is operated in the test environment described in 4.1 until it stops, which is considered as a cycle. 4.4.2 After 300 consecutive cycles of testing according to the method in 4.4.1; check whether the sample meets the requirements of 3.3.1. 4.5 Spring over-tightening strength test
4.5.1 Test apparatus
4.5.1.1 A fixture that can hold the spring key and transmit torque, see Appendix A4.5.1.2 Use a torque meter with a range of 0 to 0.8 Nm and an accuracy of 0.01 Nm. 4.5.2 Test steps
4.5.2.1 After the sample is fully wound, clamp the fixture on the spring key. 4.5.2.2 Use the torque meter to uniformly apply a torque of 0.46 N·m in the direction of further winding of the spring within 5 seconds, or rotate the spring key another 360 degrees and hold for 10 seconds. Check whether the sample meets the requirements of 3.3.2. 4.6 Quick stop strength test
After the sample is fully wound, let it operate normally, and then apply force to force it to stop operating rapidly. This test is carried out three times in succession to check whether the sample meets the requirements of 3.3.3. QB/T2360-98
