[0049] The metal parts include a first combined tube 101, a second combined tube 102, an anti-skid washer 103, a mounting seat 104, a mounting plate 105, a connecting sleeve 108 and a linkage shaft 109, and on one side of the first combined tube 101 and the second combined tube 102 Mounting bases 104 are installed, a mounting plate 105 is installed on one side of the mounting base 104, a connecting sleeve 108 is installed on the other end of the first combined pipe 101, and a connecting sleeve 108 is installed on the other end of the second combined pipe 102. The linkage shaft 109 , the inner side of the first combined pipe 101 and the second combined pipe 102 are provided with anti-slip washers 103 , and the bottoms of the mounting pla...
Embodiment 2
[0052] see Figure 1-3 Shown, a kind of production technology of the assembly device of high-strength bicycle net basket comprises the following steps:
[0053] Step 1: Add 100mL of concentrated sulfuric acid with a mass fraction of 98% and 16g of 1,5-naphthalenediol to a three-necked flask equipped with a stirrer and a constant pressure dropping funnel, at room temperature and at a stirring rate of 100r / min Stir until 1,5-naphthalenediol is completely dissolved, then add 15 mL of concentrated nitric acid with a mass fraction of 68% dropwise while stirring at a temperature of -5°C and a stirring rate of 50 r / min, and control the dropping rate at 1 drop / s, continue to stir for 20min after the dropwise addition, then raise the temperature to 25°C while stirring, control the heating rate to 1°C / min, then stir and react at constant temperature for 2h, after the reaction is completed, the reaction product is quenched with ice water, vacuum Suction filtration, washing the filter ca...
