Purchase and daily care of padlocks.
For the purchase and protection of locks, we need to pay attention to the following points.
1. First of all, it is necessary to recognize whether the product has the factory name, address, trademark and whether there is an inspection qualification statement issued by the *** quality inspection organization recently.
2. When purchasing, the material should be moderate, and the hand should be firm and reliable. Don’t choose various locks made of low-cost and low-quality materials.
3. The equipment of the lock is also a key point: the equipment must be strictly carried out in accordance with the product manual, and the center distance of the equipment, the scope of application and the opening method of the lock must be recognized. Special attention must be paid to prevent the equipment from being corroded by harmful substances on the wooden door with high humidity.
4. The appearance of the lock should be clear, not rough in appearance, and comfortable. The lock is sensitive to rotation when it is open, and the locking device should be effective. It should not feel invalid when it is in the hand. The security function should be good.
5. The padlock usually keeps the lock body clean to prevent foreign matter from entering the pin groove of the lock cylinder, causing it to be rolled when opened, and even the lock cannot be opened.
